Description

Information transmission method and network element thereof

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method and a network element thereof.

Background

For a Long Term Evolution (LTE) system, before performing Uplink transmission on data, user equipment needs to send a transmission scheduling request to a base station, and then the base station performs Uplink transmission resource allocation on the user equipment according to the request and sends an Uplink Grant (UL Grant) carrying Uplink transmission resources to the user equipment, so that the user equipment can use the Uplink transmission resources to perform Uplink data transmission. Therefore, in the conventional LTE uplink data transmission, a certain time overhead is generated when the eNB receives the uplink data transmission of the user equipment from the time when the user equipment has an uplink data transmission requirement.

With the continuous development of communication technology, the ultra-reliable low-latency communication technology of the fifth generation mobile communication technology (5G) is becoming the current mainstream trend, and on the other hand, data transmission using Unlicensed frequency band (Unlicensed spectrum) resources is also one of the future data transmission trends. The coexistence specifications corresponding to the 5GHz unlicensed band resource include Transmit Power Control (TPC), Dynamic Frequency Selection (DFS), channel occupied bandwidth and Listen Before Talk (LBT), etc. Taking LBT as an example, if uplink data transmission is performed on the unlicensed frequency band resource, both the ue and the base station need to contend for the unlicensed frequency spectrum resource through LBT, and when the number of required LBTs is more, the transmission difficulty is greater.

Uplink data transmission without an Uplink Grant free (UL Grant free) is one of the future data transmission trends. Before the user equipment transmits uplink data through the UL grant free, the user equipment does not need to wait for the dynamic scheduling indication information of the base station, so that the time overhead of uplink data transmission can be reduced, the uplink data can be transmitted on the license-free frequency band resource, and the LBT times can be reduced. On the other hand, in order to ensure uplink data transmission efficiency in the existing data transmission mode, the base station generally dynamically sends uplink control information corresponding to uplink data transmission to the user equipment, so as to implement link adaptation and further ensure uplink data transmission efficiency. However, for the UL grant free based uplink data transmission scheme, the uplink data transmission of the ue no longer depends on the dynamic notification of the base station. Therefore, how to ensure the transmission efficiency of the uplink data and ensure that the transmission of the uplink data can be adapted to the uplink transmission channel while realizing the UL grant free transmission becomes a problem to be solved at present.

Detailed Description

The embodiment of the invention can be applied to wireless communication systems, including an LTE system, a 4.5G wireless communication system or a 5G wireless communication system, can be applied to licensed frequency spectrums and can also be applied to unlicensed frequency spectrums. When applied to an unlicensed spectrum, the LTE system may be used for Licensed Assisted Access (LAA), i.e., an LAA-LTE system. The LTE system with auxiliary access to the licensed band refers to an LTE system in which the licensed band and the unlicensed band are used together in a Carrier Aggregation (CA) manner or a non-CA manner, which may be Dual Connectivity (DC), for example.

The LAA-LTE system corresponds to a scenario in which a licensed frequency band and an unlicensed frequency band are jointly used by carrier aggregation CA, that is, a carrier included in the licensed frequency band or a cell operating on the licensed frequency band is used as a main cell, and a carrier included in the unlicensed frequency band or a cell operating on the unlicensed frequency band is used as an auxiliary cell, where the main cell and the auxiliary cell may be deployed in a co-site manner or in a non-co-site manner, and an ideal backhaul path is provided between the two cells.

When the invention is applied to the unlicensed frequency band, the invention is not limited to the CA scenario and other deployment scenarios, and also includes a scenario where there is no ideal backhaul path between two cells (a main cell and an auxiliary cell), for example, backhaul delay is large, which results in that information cannot be quickly coordinated between the two cells, for example, a DC scenario. In addition, the method can also be applied to a cell operating on an unlicensed frequency band in an independent deployment, that is, a serving cell operating on the unlicensed frequency band at this time can directly provide an independent access function without assistance of a cell operating on the licensed frequency band, for example, a standby LTE over unlicensed spectrum (standby ULTE) system.

In the embodiment of the present invention, the network elements mainly refer to a base station and user equipment that can operate on an unlicensed frequency band. User Equipment (UE) may include a Relay in addition to a common User terminal such as a mobile phone and a tablet computer, that is, the UE may be used for data communication with a base station. Before describing the embodiments, some brief descriptions will be made on the concepts of base station, cell, spectrum, carrier, etc. involved in the present invention.

In the embodiment of the present invention, the licensed frequency band or the unlicensed frequency band may include one or more carriers, and the carrier aggregation may be performed on the licensed frequency band and the unlicensed frequency band, and may include carrier aggregation performed on one or more carriers included in the licensed frequency band and one or more carriers included in the unlicensed frequency band.

In the present invention, the cell mentioned may be a cell corresponding to a base station, and the cell may belong to a macro base station, and may also belong to a base station corresponding to a small cell (small cell), where the small cell may include: urban cells (Metro cells), Micro cells (Micro cells), Pico cells (Pico cells), Femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services.

The carrier in the LTE system may have multiple cells working at the same frequency, and under some special scenarios, the concept of the carrier in the LTE system and the concept of the cell may also be considered to be the same. For example, in a CA scenario, when configuring a secondary carrier for a UE, the secondary carrier may simultaneously carry a carrier index of the secondary carrier and a Cell identity (Cell ID) of a secondary Cell operating on the secondary carrier, and in this case, the concept of the carrier and the Cell may be considered to be equivalent, for example, it is equivalent that the UE accesses one carrier and one Cell. DC and standalone ULTE can also be based on this understanding. The present invention will be described by taking a cell as an example.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic flow chart of a UL grant free transmission according to an embodiment of the present invention. Generally, when the user equipment performs uplink data transmission, the user equipment needs to send a transmission scheduling request to the base station, then the base station performs uplink transmission resource allocation to the user equipment according to the request, and sends a UL grant carrying the uplink transmission resource to the user equipment, so that the user equipment can perform uplink data transmission by using the uplink transmission resource. In the embodiment of the present invention, as shown in fig. 1, the UL grant free is adopted for data transmission, so that the ue determines the uplink control information without waiting for the dynamic scheduling indication information of the base station, and after the uplink control information and the uplink data are preprocessed, the preprocessed uplink control information and the preprocessed uplink data are sent to the base station through the physical uplink channel, thereby improving the transmission efficiency of the uplink data and ensuring that the transmission of the uplink data can be adapted to the uplink transmission channel.

Referring to fig. 2, fig. 2 is a schematic flow chart of an information transmission method according to an embodiment of the present invention. As shown in fig. 2, the information transmission method includes steps S101 to S103.

S101, the user equipment determines uplink control information corresponding to uplink data transmitted in a first time unit.

Specifically, when the user equipment has a requirement for uplink data transmission, it may be determined that the uplink data is transmitted in the first time unit. In a possible embodiment, the Time unit may be represented by a Transmission Time Interval (TTI), and the TTI may be measured in milliseconds (ms) or Orthogonal Frequency Division Multiplexing (OFDM), and the Time unit in the embodiment of the present invention is represented by using the TTI as an example. For example, 1 TTI may be 0.5ms, or 1 TTI may be 2 OFDM symbols. The first time unit may be a time unit closest to the uplink transmission required time of the user equipment, or may be a time unit delayed by a certain time range from the uplink transmission required time of the user equipment. For example, when the user equipment needs to perform uplink data transmission, it needs a certain time to perform processing such as encoding and modulation on the uplink data, and therefore a certain delay time is needed before the first time unit to process the uplink data. As shown in fig. 2a, fig. 2a is a schematic diagram of uplink data transmission according to an embodiment of the present invention, where the ue has an uplink data transmission requirement in the first TTI shown in fig. 2a, then performs uplink data transmission processing in the period a, and performs uplink data transmission in the first period (the first time unit in fig. 2 a).

Optionally, in another possible embodiment, the first time unit may also be an Uplink duration (UL duration) on the unlicensed frequency band, and the UL duration may be preconfigured by the base station, for example, the base station performs the preconfigured operation by sending a Radio Resource Control (RRC) signaling indication or a dynamic notification to the ue. Optionally, the UL duration may also be determined by a Common Control information indication on the licensed band or the unlicensed band, where the Common Control information may be transmitted through a Common Physical Downlink Control Channel (C-PDCCH), or may be scrambled by using a Cell Common Radio Network Temporary Identity (CC-RNTI), and the Common Control information may also be used to indicate an end position of the Downlink burst data transmission. As shown in fig. 2b, fig. 2b is a schematic diagram of notifying the UL duration of the unlicensed band C-PDCCH according to an embodiment of the present invention, where the UL duration notified by the C-PDCCH may include a first time unit. Optionally, the UL duration and the downlink TTI in which the C-PDCCH is located belong to the same Transmission Opportunity (TxOP), and the TxOP may indicate a time that a device (e.g., a user equipment or a base station) continuously uses on an unlicensed frequency band without re-evaluating a Channel through a CCA after competing for a usage Opportunity of the unlicensed frequency band resource through a Clear Channel Assessment (CCA) (e.g., LBT). Therefore, the TxOP may include only the downlink time units, only the uplink time units, and both the downlink time units and the uplink time units. The downlink time unit refers to a time unit for transmitting downlink data, and the uplink time unit refers to a time unit for transmitting uplink data. A time unit may include a downlink data transmission and/or an uplink data transmission, and is not limited herein. Optionally, the TxOP may also be a Channel Occupancy period (Channel Occupancy) or a Maximum Channel Occupancy duration (MCOT). The downlink burst data transmission in fig. 2b represents the time for the eNB to perform downlink data transmission after contending to the unlicensed frequency band resource through CCA (e.g., LBT). The idle time unit may be used for the ue to perform CCA, but is not limited thereto.

In this embodiment of the present invention, optionally, the first time unit may include transmission of uplink control information, or may not include transmission of uplink control information; in other words, the uplink control information may be transmitted through a physical uplink channel included in the first time unit, or may be transmitted through a physical uplink channel included in another time unit different from the first time unit.

In this embodiment of the present invention, the uplink data may be new transmission data or retransmission data, where optionally, the new transmission data may be data transmission based on a UL grant free, or the first new transmission data transmitted by the user equipment to the base station is data transmission based on the UL grant free, and the retransmission data may be data transmission based on the UL grant free or the UL grant. For example, after the ue sends new transmission data to the base station based on the UL grant free, the base station receives the new transmission data but fails to process the new transmission data through demodulation or decoding, and the base station schedules the new transmission data for retransmission based on the UL grant. For another example, when the uplink transmission buffer is not zero, the ue transmits the first new transmission data to the base station based on the UL grant free, and then the transmitted uplink data (new transmission data or retransmission data) are transmitted based on the UL grant until the buffer of the ue is zero.

In the embodiment of the present invention, the uplink data may include uplink service data transmitted by the user equipment, or may also include uplink service data and an uplink reference signal transmitted by the user equipment, where the uplink reference signal may be used for demodulation of the uplink service data. The uplink control information may include Hybrid Automatic Repeat Request (HARQ) information corresponding to uplink data, where the HARQ information includes at least one of: HARQ Process Number (HPN), New Data Indication (NDI) information, and Redundancy Version (RV) information (for accurately completing HARQ combining of uplink Data). Optionally, the uplink control information only includes HARQ information. Optionally, the uplink control information may further include at least one of the following: modulation Coding Scheme (MCS), Resource Allocation (RA) information, Transport Block Size (TBS) corresponding to uplink data, Transmit Power Control (TPC), User Equipment identity Identification (UE ID), and the like. Optionally, more generally, the uplink Control Information based on the UL Grant free may also be referred to as a GCI (Grant-free Control Information), the GCI may include content included in Downlink Control Information used for scheduling uplink data transmission in an existing LTE system or a future 5G communication system, taking the LTE system as an example, the GCI may include at least one piece of uplink Control Information used in the UL Grant, and in the LTE system, the UL Grant may be represented by a Downlink Control Information Format 0(Downlink Control Information Format 0, DCI Format 0), DCI Format 4, DCI Format 0A, DCI Format 0B, DCI Format 4A, and DCI Format 4B, but is not limited thereto.

Optionally, the information may be preconfigured through RRC signaling sent by the base station, or may be predefined by the base station, but the uplink control information determined to be used by the ue is selected by the ue and reported to the base station.

In the embodiment of the invention, the HPN can be used for distinguishing different uplink data. When a user performs uplink data transmission, in order to ensure the transmission efficiency of uplink data, a base station may feed back an Acknowledgement (ACK) or a Non-Acknowledgement (NACK) to a user equipment (ue) after receiving uplink data transmitted by the ue. Since the base station needs a certain time for processing, such as demodulation or decoding, of the uplink data, in order to improve uplink transmission efficiency, the ue may continue to transmit the uplink data to the base station within a time range in which the base station processes the uplink data. In order to facilitate the base station to identify different uplink data or perform HARQ combining processing on the uplink data, an HPN may be introduced, and the user equipment reports the HPN to the base station, so that the base station can distinguish different uplink data transmitted by the user equipment according to the HPN. For example, the base station performs ACK or NACK feedback on all received uplink data or uplink data that is received and has no ACK or NACK feedback at a certain time. As shown in fig. 2c, fig. 2c is a schematic diagram that a base station feeds back multiple ACKs or NACKs at the same time according to an embodiment of the present invention, where the base station receives Uplink data transmitted through a PUSCH-1 and Uplink data transmitted through a PUSCH-2 in a first TTI and a second TTI, respectively, and feeds back the ACK or NACK in a fourth TTI, where the Uplink data is carried in a Physical Uplink Shared Channel (PUSCH) for transmission. When the base station receives the HPN, different uplink data can be distinguished according to the HPN.

As shown in fig. 2d, fig. 2d is a schematic diagram of data transmission without NDI according to an embodiment of the present invention. The user equipment sends uplink data A in a first TTI and assumes that the HPN corresponding to the uplink data A is 1; after receiving the uplink data A, the base station performs operations such as decoding and the like, determines that the uplink data A is correctly received, and performs ACK feedback to the user equipment at a specific time (for example, a third TTI); if the ue does not receive ACK or receives ACK but erroneously detects NACK, the ue may misunderstand that the base station does not receive the uplink data a or receives the uplink data a but fails in decoding, and at this time, the ue retransmits the uplink data a (assumed as a ') at a specific time (e.g. a fifth TTI), and at this time, the HPN corresponding to the uplink data a' is also 1. If the base station receives the uplink data a 'in the fifth TTI, since the base station has fed back ACK to the uplink data a before, the base station may misunderstand that the uplink data a' is new data, and perform operations such as decoding on the data, and perform unnecessary data processing.

As shown in fig. 2e, fig. 2e is a schematic diagram of another data transmission without NDI according to an embodiment of the present invention. The user equipment sends uplink data A in a first TTI and assumes that the HPN corresponding to the uplink data A is 1; after receiving the uplink data a and performing processing such as decoding, the base station determines that the uplink data a is received incorrectly, which is that the base station performs NACK feedback on the received uplink data a at a specific time (for example, a third TTI); if the ue erroneously detects NACK as ACK, the ue will continue to transmit the second uplink data B at a specific time (e.g. the fifth TTI), and the HPN of the uplink data B is also assumed to be 1. After the base station receives the uplink data B, because the HPNs corresponding to the uplink data a and the uplink data B are both 1 and the base station performs NACK feedback on the uplink data a, the base station may misunderstand the uplink data B as retransmission of the uplink data a, and thus HARQ combining is performed on the uplink data a and the uplink data B, which obviously is inaccurate.

In the embodiment of the present invention, when the base station performs HARQ combining processing on uplink data, in order to ensure the accuracy of HARQ combining and reduce unnecessary data processing, the base station needs to know whether new transmission data or retransmission data is transmitted when the uplink data is sent by the user equipment, so that NDI is introduced. In the embodiment of the present invention, whether the NDI is inverted may be used to indicate whether the data is newly transmitted or retransmitted. For example, the ue transmits new transmission data a to the base station, where the HPN corresponding to the new transmission data a is 1, and the ue may set the NDI to zero; if the user equipment determines that the base station does not correctly receive the uplink data A, the user equipment retransmits the uplink data to the base station, and the NDI is still 0 at this moment; if the ue determines that the base station correctly receives the uplink data a, the ue may transmit new uplink data through the HARQ process with HPN of 1, where NDI may be set to 1, i.e., whether to transmit new data or retransmit data may be distinguished by turning the NDI. Optionally, in the embodiment of the present invention, a fixed value may be set for the NDI to distinguish between new transmission data and retransmission data. For example, setting NDI to 0 indicates new transmission data, setting NDI to 1 indicates retransmission data, the ue transmits new transmission data a to the base station, and sets NDI to 0 to indicate that the current transmission data is the new transmission data, and if the ue determines that the base station does not correctly receive the uplink data a, the ue retransmits the uplink data a to the base station, and at this time, sets NDI to 0 to indicate that the current transmission data is the retransmission data.

In the embodiment of the present invention, when the base station performs HARQ combining of uplink data, in order to obtain HARQ combining gain, the user equipment may adopt different RVs when retransmitting the uplink data. In order to ensure the gain of HARQ combining, the ue may transmit the RV corresponding to the uplink data to the base station through a physical uplink channel.

S102, the user equipment preprocesses the uplink control information and the uplink data.

Specifically, the pre-processing, by the ue, the uplink control information and the uplink data may include two cases: the first is independent preprocessing, that is, resources occupied by the uplink control information and the uplink data can be determined according to respective performance target requirements, and the respective preprocessing is performed, for example, the uplink control information corresponds to the first preprocessing, and the uplink data corresponds to the second preprocessing; the second is joint preprocessing, that is, resources occupied by the uplink control information and the uplink data may be determined, and then joint preprocessing is performed. Optionally, the preprocessing (which may also be the first preprocessing or the second preprocessing) may include at least one of sequence modulation, channel coding, and rate matching. Further optionally, the preprocessing (which may also be the first preprocessing or the second preprocessing) may include other processing manners, such as channel interleaving, constellation modulation, resource mapping, precoding, and the like, besides sequence modulation, channel coding, and rate matching, for the base station to obtain corresponding information according to the received uplink data.

It should be noted that, in the embodiment of the present invention, when the preprocessing includes channel coding, a first preprocessing manner (i.e., an independent preprocessing manner) may be understood as that the ue performs channel coding on the uplink control information and the uplink data, respectively, that is, the uplink control information and the uplink data are independently coded; the second preprocessing mode (i.e. joint preprocessing mode) may be understood as that the ue jointly encodes the uplink control information and the uplink data, i.e. the uplink control information and the uplink data are jointly encoded.

And S103, the user equipment transmits the preprocessed uplink control information and uplink data to a base station through a physical uplink channel.

Specifically, the ue transmits the preprocessed uplink control information and uplink data to the base station through a physical uplink channel. The Physical Uplink Channel may be a Physical Uplink Shared Channel (PUSCH), or may be another Channel for carrying Uplink data and/or Uplink Control information, for example, a Physical Uplink Control Channel (PUCCH). After receiving the preprocessed uplink control information and the preprocessed uplink data, the base station may perform inverse processing (i.e., an inverse process of the preprocessing, which may include at least one of channel decoding, and rate matching) on the preprocessed uplink control information and the preprocessed uplink data, for example, when the preprocessing mode adopted by the user equipment is channel coding, the base station adopts the inverse processing mode to decode the channel, so as to recover the uplink control information and the uplink data.

It should be noted that, in the embodiment of the present invention, the ue may transmit the preprocessed uplink control information and the preprocessed uplink data to the base station through the same physical uplink channel, or may transmit the preprocessed uplink control information and the preprocessed uplink data to the base station through different physical uplink channels, that is, the physical uplink channel in S103 may be understood as the same physical uplink channel, and may also be understood as different physical uplink channels.

In the embodiment of the invention, the user equipment determines the uplink control information corresponding to the uplink data transmitted in the first time unit, then preprocesses the uplink control information and the uplink data, transmits the preprocessed uplink control information and the preprocessed uplink data to the base station through a physical uplink channel, and transmits the uplink data and the uplink control information to the base station through the user equipment, so that the transmission of UL grant free is realized, the transmission efficiency of the uplink data is ensured, and the uplink data transmission can be adapted to the uplink transmission channel.

Referring to fig. 3, fig. 3 is a schematic flow chart of another information transmission method according to an embodiment of the present invention. As shown in fig. 3, the other information transmission method includes steps S201 to S206.

S201, the ue determines uplink control information corresponding to uplink data transmitted in a first time unit.

Specifically, please refer to the detailed description of step S101 in fig. 2 for a partial explanation of step S201, which is not repeated herein.

Optionally, the first time unit is one time unit in a time set, and the time set includes at least two time units; and the user equipment determines uplink control information corresponding to other time units except the first time unit in the time set according to the uplink control information corresponding to the first time unit and a first preset rule. Optionally, the other time units in the time set except the first time unit may include all time units in the time set except the first time unit.

Specifically, in the embodiment of the present invention, the uplink control information may include, in addition to the control information corresponding to the uplink data transmitted in the first time unit, control information corresponding to the uplink data transmitted in other time units except the first time unit. The other time units and the first time unit may be continuous time units or discontinuous time units, and are not particularly limited in the embodiment of the present invention. Taking the first time unit and the other time units as consecutive time units as an example, as shown in fig. 3a, fig. 3a is a schematic diagram of a time set. The uplink control information corresponding to the first time unit may also indicate uplink control information corresponding to uplink data respectively transmitted by other time units, such as the second time unit, the third time unit, and the fourth time unit, and the specific indication manners may include two manners: in a first indication mode, uplink control information included in a first time unit directly includes uplink control information corresponding to uplink data respectively transmitted in other time units; in a second indication manner, the first time unit only includes uplink control information corresponding to uplink data transmitted in the first time unit, and then uplink control information corresponding to uplink data respectively transmitted in other time units is determined according to a first preset rule. For example, in the second indication manner, assuming that uplink control information (taking HARQ process number as an example) not included in the first time unit indicates that the HARQ process number corresponding to the uplink data transmitted in the first time unit is HPN1, the user equipment may determine, according to the HPN1 and a first preset rule, the HARQ process number corresponding to the uplink data transmitted in another time unit in the time set. If the HARQ process numbers corresponding to the uplink data transmitted in the second time unit, the third time unit, and the fourth time unit are HPN2, HPN3, and HPN3, respectively, then HPN2 ═ HPN1+1 or HPN2 ═ HPN1+1) mod N, HPN3 ═ HPN1+2 or HPN3 ═ HPN1+2) mod N, HPN4 ═ HPN1+3, or HPN4 ═ HPN1+3) mod N, where N represents the maximum number of HPNs, and mod is a remainder operator. By this embodiment, control information overhead can be saved. For another example, in the first indication manner, the uplink control information included in the first time unit directly includes the HPN1, the HPN2, the HPN3, and the HPN 4. The HPN1, the HPN2, the HPN3, and the HPN4 correspond to HARQ process numbers corresponding to uplink data transmitted in each of the first time unit, the second time unit, the third time unit, and the fourth time unit, respectively. It should be noted that, in the embodiment of the present invention, the first preset rule may be preconfigured or predefined.

Optionally, the uplink data may be transmitted through at least two uplink codewords, and the uplink control information refers to control information corresponding to a first uplink codeword in the uplink data; and the user equipment determines uplink control information corresponding to other uplink code words except the first uplink code word in the uplink data according to the first uplink code word and a second preset rule. Specifically, the uplink data may be transmitted through at least two uplink codewords, the uplink control information may be control information corresponding to a first uplink codeword in the uplink data, and the user equipment may determine, according to the first uplink codeword and a second preset rule, uplink control information corresponding to all uplink codewords except the first uplink codeword in the uplink data. Still taking the uplink control information as the HPN as an example, assuming that the uplink data may include four uplink codewords (uplink space division data transmission), i.e., the first uplink codeword to the fourth uplink codeword, the uplink control information HPN1 may be for the first uplink codeword, and the second uplink codeword to the fourth uplink codeword correspond to the HPN2, the HPN3, and the HPN4, respectively. The user equipment may determine, according to the HPN1 corresponding to the first uplink codeword and a second preset rule, that HPN2 ═ HPN1+1 or (HPN2 ═ HPN1+1) mod N, HPN3 ═ HPN1+2 or (HPN3 ═ HPN1+2) mod N, and HPN4 ═ HPN1+3 or (HPN4 ═ HPN1+3) mod N. Where N represents the maximum number of HPNs and mod is the remainder operator.

S202, the user equipment obtains a first resource occupied by the uplink control information and a second resource occupied by the uplink data.

Specifically, in this embodiment of the present invention, the first resource may be a modulation symbol number, a coding bit number, or a sequence, such as a Demodulation Reference Signal (DMRS) sequence, or a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence, or an m sequence, or a pseudo-random sequence, or another type of sequence; the second resource may be the number of modulation symbols, the number of coding bits, or a sequence such as a DMRS sequence, or an amplitude-constant zero correlation CAZAC sequence, or an m-sequence, or a pseudo-random sequence, or another type of sequence. The user equipment obtains the first resource occupied by the uplink control information, namely the user equipment calculates the number of modulation symbols and the number of coding bits occupied by the uplink control information or the sequence used by the user equipment for transmitting the uplink control information; the user equipment obtains the second resource occupied by the uplink data, namely the coding bit number and the modulation symbol number occupied by the uplink data on the user equipment or the sequence used by the user equipment for transmitting the uplink control information. The number of modulation symbols, the number of coding bits, or the sequence used for transmitting the uplink control information may be the same as or different from the number of modulation symbols, the number of coding bits, or the sequence used for transmitting the uplink data.

Optionally, the first resource is obtained by calculating according to the effective information bit number corresponding to the uplink control information, the target information bit number corresponding to the uplink data, and the target resource corresponding to the uplink data; the target information bit number corresponding to the uplink data is an effective information bit number corresponding to the uplink data or a preset information bit number corresponding to the uplink data, and the target resource corresponding to the uplink data is the capacity of the second physical uplink channel or a preset resource corresponding to the uplink data.

Optionally, the first resource may also be a preset resource corresponding to the uplink control information.

Optionally, the first resource may also be obtained by calculation according to the effective information bit number and the modulation and coding scheme MCS corresponding to the uplink control information. In this way, the MCS may be pre-configured or predefined, the MCS may be the same as or different from an MCS corresponding to uplink data, and the number of valid information bits corresponding to the uplink control information is pre-configured or predefined. For example, for the uplink control information, a QPSK modulation scheme is preconfigured, the coding rate is fixed, and the preconfigured effective information bit number is Xbit, then the user equipment may obtain the first resource represented by the coding bit number by X/(fixed coding rate)/2 calculation, where 2 is a modulation order corresponding to QPSK.

Specifically, the determining manner of the first resource may specifically include the following:

first, the user equipment determines a first resource according to the effective information bit number corresponding to the uplink control information, the effective information bit number corresponding to the uplink data, and the capacity of a second physical uplink channel.

In the embodiment of the present invention, a physical uplink channel (a first physical uplink channel) for transmitting the uplink control information after the first preprocessing may be the same as or different from a physical uplink channel (a second physical uplink channel) for transmitting the uplink data after the second preprocessing. It should be noted that, in the embodiment of the present invention, when the first physical uplink channel is the same as the second physical uplink channel, that is, when the uplink control information and the uplink data are transmitted through the same physical uplink channel, the same physical uplink channel may be represented by the second physical uplink channel or may be represented by the first physical uplink channel, and accordingly, the capacity of the second physical uplink channel is equal to the capacity of the physical uplink channel including the transmission of the uplink control information and the uplink data; when the first physical uplink channel is different from the second physical uplink channel, the second physical uplink channel is a channel including uplink data transmission, and accordingly, the capacity of the second physical uplink channel is equal to the capacity of the physical uplink channel including uplink data transmission. In the embodiment of the present invention, the capacity of the physical uplink channel may be represented by the number of modulation symbols or the number of coding bits.

It should be noted that, in this embodiment of the present invention, the ue may further determine the first resource according to the number of effective information bits corresponding to the uplink control information, the number of effective information bits corresponding to the uplink data, and the second resource. In this manner, the second resource may be pre-configured or predefined. When the first physical uplink channel is the same as the second physical uplink channel, the capacity of the second physical uplink channel includes a second resource, and in this case, the capacity of the second physical uplink channel may be equal to or greater than the second resource, and when the capacity of the second physical uplink channel is greater than the second resource, the second resource is that part of the second physical uplink channel used for transmitting uplink data, that is, the second resource is a difference between the capacity of the second physical uplink channel and the first resource. When the first physical uplink channel is different from the second physical uplink channel, the capacity of the second physical uplink channel is equal to the second resource. For example, when the second resource is represented by the modulation symbol number, the modulation symbol number occupied by the second resource is Q'_UL-SCHQ ', or Q'_UL-SCH＝Q′-Q′_CI. Wherein Q 'is the capacity (expressed by the number of modulation symbols) of a second physical uplink channel comprising the transmission of uplink data (corresponding to the case where the first physical uplink channel is different from the second physical uplink channel) or comprising the transmission of uplink data and uplink control information (corresponding to the case where the first physical uplink channel is the same as the second physical uplink channel), Q'_CIThe number of modulation symbols occupied by the first resource.

Several specific ways of calculating the first resource are described below by taking "the user equipment determines the first resource according to the effective information bit number corresponding to the uplink control information, the effective information bit number corresponding to the uplink data, and the capacity of the second physical uplink channel" as an example. It should be noted that, when the "user equipment determines the first resource according to the number of effective information bits corresponding to the uplink control information, the number of effective information bits corresponding to the uplink data, and the second resource", the "capacity of the second physical uplink channel" in the following formula may be replaced with the "second resource".

First resource (taking number of modulation symbols as an example) Q 'occupied by uplink control information'_CIThe calculation formula of (c) may be any one of:

in the above-mentioned formula,

denotes the rounding of the pair, Q' denotes the capacity of the second physical uplink channel expressed by the number of modulation symbols, O_CIIndicating the number of valid information bits, O, corresponding to the uplink control information_UL-SCHAnd the effective information bit number corresponding to the uplink data is shown. In the formula (2) and the formula (4), β_offsetA semi-statically configured value or a predefined value for higher layer signaling, wherein the higher layer signaling may be Radio Resource Control (RRC) signaling or Medium Access Control (MAC) signaling. Beta is a_offsetThe method can be used for adjusting the channel coding code rate of the uplink control information, and effectively utilizes transmission resources while ensuring the performance of the uplink control information.

Optionally, the capacity of the second Physical Uplink Channel (PUCH) may be calculated by formula (5).

Wherein the content of the first and second substances,

indicates the number of sub-carriers allocated to the physical uplink channel,

the number of time domain symbols occupied by the second physical uplink channel is represented, or the number of time domain symbols used for transmitting uplink control information and uplink data in the second physical uplink channel is represented (where the uplink control information and the uplink data are carried in the same physical uplink channel), or the number of time domain symbols used for transmitting uplink data in the second physical uplink channel is represented. Taking Long Term Evolution (LTE) system as an example, assuming that one time unit is one Subframe (Subframe), the Subframe is a time unit

The calculation formula (6) is as follows:

wherein the content of the first and second substances,

and the number of time domain symbols occupied by one time Slot (Slot) of the second physical uplink channel is represented. Under a normal Cyclic Prefix (CP),

under extended CP

N_DMRSIndicating the number of symbols used for transmitting the DMRS in a subframe of the second Physical Uplink Channel, e.g., N when the second Physical Uplink Channel is a Physical Uplink Shared Channel (PUSCH)_DMRS＝2。N_SRSIndicating a current subframe for transmitting sounding parametersThe number of symbols of the Reference Signal (SRS), N, if there is SRS transmission in the current subframe_SRSFor the number of time domain symbols used for transmitting SRS, if no SRS is currently transmitted, N_SRS＝0。

Optionally, the second physical uplink channel may implement transmission of multiple uplink data or uplink data of multiple user equipments in an orthogonal multiplexing manner, where multiplexing refers to that multiple uplink data may be transmitted using the same time resource and frequency resource, and the base station can distinguish the multiple uplink data; or, multiplexing means that uplink data transmission of multiple user equipments can use the same time resource and frequency resource for transmission, and the base station can distinguish the uplink data transmission of the multiple user equipments. Multiplexing may be implemented by space division orthogonal, for example, using different space division codes for multiple uplink data to implement space division multiplexing, or may also be implemented by non-orthogonal multiplexing, which is not specifically limited in the embodiment of the present invention. The capacity of the PUCH in this case can also be calculated by equation (7):

wherein, V_SFIs the value of the spreading factor. For example, taking LTE as an example, assuming that a physical uplink channel occupies 1 subframe in time, and one subframe includes 2 slots, each slot includes 7 OFDM symbols, the physical uplink channel occupies 12 subcarriers in frequency, and two symbols in one subframe are used for transmission of DMRS, and the subframe does not include SRS, the physical uplink channel can be calculated to include 12 × 7-2 — 144 Resource Elements (REs) according to equation (6). If each RE can carry one modulation symbol, the physical uplink capacity is 144 modulation symbols.

It is assumed that through some orthogonal method, the simultaneous transmission of 4 different uplink data, i.e. V, can be realized on the physical uplink channel_SFWhen the physical number is 4, the capacity of the PUCH is 36(144/4) modulation symbols according to equation (7), that is, when the physical number is equal toWhen the uplink channel carries 4 different uplink data, the capacity of the physical uplink channel corresponding to each uplink data transmission is 36 modulation symbols. The four different uplink data may be transmitted by one UE or multiple UEs.

Optionally, when the first resource occupied by the uplink control information is calculated, the result calculated by the formulas (1) to (4) may be compared with a preconfigured resource amount (which may be represented by the number of modulation symbols or the number of coding bits, with a/B/C/D as the preconfigured resource amount). The concrete formulas are as shown in (8) to (11).

It should be noted that, in the embodiment of the present invention, the rounding-up operator in any one of the above formulas

Can be replaced by a round-down operator

The operator min (-) taking a smaller value as the output result may be replaced with the operator max (-) taking a larger value as the output result. Alternatively, the a/B/C/D may be related to the maximum number of OFDM symbols occupied by the uplink control information in the physical uplink channel. For example, when uplink control information and uplink data are transmitted through the same physical uplink channel, it is assumed that the uplink control information and the uplink data are transmitted through the same physical uplink channelThe row control information occupies at most 2 OFDM symbols in the second physical uplink channel, and the A/B/C/D can be expressed as

Wherein

In the embodiment of the invention, the effective information bit number O corresponding to the uplink control information_CIThe ue may be preconfigured by the base station, or predefined, or determined by the hardware condition of the ue, which is not specifically limited in the embodiment of the present invention. For example, if the number of uplink HARQ buffers supported by the ue is 8, the HPN may be represented by 3 bits, i.e. O_CI3. For another example, the uplink control information includes HPNs for a plurality of time units, each time unit corresponds to an HPN, the HPNs can be represented by 3 bits, when there are N time units (N ≧ 1, and is a natural number) whose HPNs need to be indicated, in one possible manner, O_CI＝3N。

In the embodiment of the present invention, the number of valid information bits corresponding to the uplink data may be pre-configured or predefined, for example, pre-configured to 32 Bytes (Bytes). The number of effective information bits corresponding to the uplink data may also be changed within a set of preconfigured information bits, for example, the set of effective information bits corresponding to the uplink data configured by the base station includes K number of bits, specifically { bit number 1, bit number 2, … …, bit number K }, and the user equipment may select the number of effective information bits corresponding to the uplink data in the set, and calculate the first resource according to the selected number of effective information bits corresponding to the uplink data. In this way, the base station may determine the effective information bit number corresponding to the uplink data and/or determine the first resource in a blind detection manner. Optionally, the number of effective information bits corresponding to the uplink data may be obtained by calculating or looking up a table through a second resource occupied by the uplink data and an MCS corresponding to the uplink data, where the second resource and/or the MCS may be preconfigured or predefined. Further optionally, a Resource Allocation (RA) corresponding to the second Resource is preconfigured, where the RA includes an indication of a location in time and frequency of a physical uplink channel for transmitting uplink data. The user equipment can calculate the second resource through the RA, and then can determine the effective information bit number corresponding to the uplink data according to the second resource and the MCS. Optionally, in this embodiment of the present invention, the number of effective information bits corresponding to uplink data may correspond to a Transport Block Size (TBS). It should be noted that, when the user equipment determines the effective information bit number corresponding to the uplink data through the second resource and the MCS, the second resource may also be represented by the number of RBs occupied by the physical uplink channel under the condition that the time resource of the physical uplink channel is fixed. Here, the term "fixed time resource" means that, taking LTE system as an example, the physical uplink channel may occupy 1 subframe in time. Therefore, the user equipment may determine the number of effective information bits corresponding to the uplink data according to the number of RBs and the MCS corresponding to the uplink data, for example, by looking up a table according to the number of RBs and the MCS corresponding to the uplink data (for example, by using an MCS index, which is in one-to-one correspondence with the MCS).

The capacity of the second physical uplink channel is a capacity of a physical uplink channel for transmitting the uplink control information and the uplink data, or a capacity of a physical uplink channel for transmitting the uplink data. The capacity of the second physical uplink channel may be represented by the number of modulation symbols or the number of coded bits. The capacity of the second physical uplink channel may be preconfigured or predefined by the base station, or may be calculated according to the target information bit number and the MCS corresponding to the uplink data, and the target information bit number and/or the MCS corresponding to the uplink data may be preconfigured or predefined, which is not specifically limited in the embodiment of the present invention.

It should be noted that, in the embodiment of the present invention, the effective information bit number of the uplink control information may be understood as an original information bit number of the uplink control information, or an information bit number after Cyclic Redundancy Check (CRC) is introduced into the original information bit number of the uplink control information; accordingly, the effective information bit number of the uplink data can be understood as the original information bit number of the uplink data, or the information bit number after the original information bit number of the uplink data introduces the CRC.

Taking the first resource occupied by the uplink control information as an example of the number of coded bits, there are two determination methods for the first resource: first, the modulation symbol number Q 'calculated by any one of the above calculation formulas (1) to (4) or formulas (8) to (11)'_CIMultiplying by modulation order Q corresponding to uplink control information_mObtaining a first resource (expressed by the number of coded bits); secondly, the modulation symbol number Q 'in the above calculation formulas (1) to (4) or formulas (8) to (11)'_CIBy the number of coded bits Q_CIInstead, Q_CIThe capacity of the second physical uplink channel is also expressed by the number of coded bits, i.e. Q' is expressed by Q, and Q is also the capacity of the second physical uplink channel (calculated by the number of coded bits). Modulation order Q_mThe correspondence between different modulation schemes is shown in table 1. Where BPSK denotes Binary Phase Shift Keying (BPSK), QPSK denotes Quadrature Phase Shift Keying (QPSK), 16QAM denotes Quadrature Amplitude Modulation (QAM) of 16 symbols, 64QAM denotes Quadrature Amplitude Modulation (QAM) of 64 symbols, and 256QAM denotes QAM of 256 symbols.

And secondly, the user equipment determines the first resource according to the effective information bit number corresponding to the uplink control information, the preset information bit number corresponding to the uplink data and the physical uplink channel capacity.

In the embodiment of the present invention, when the user transmits uplink data, the number of information bits corresponding to the uplink data may be multiple, and one of the number of information bits corresponding to the multiple uplink data may be selected as the preset information bit number O according to the uplink service transmission requirement or other factors_ini. And the base station indicates the preset information bit of the uplink data of the user equipment through the downlink control information.

The second method is mainly different from the first method in that one of the parameters used in calculating the first resource is replaced by "the number of valid information bits corresponding to uplink data" to "the number of preset information bits corresponding to uplink data", that is, O_UL-SCHReplacement by O_iniOther parameters may remain unchanged. Based on the transmission mode of the UL grant free, when the user equipment transmits the uplink data, the effective information ratio corresponding to the uplink dataThe number of bits may be varied to achieve link adaptation and/or traffic adaptation. When the user equipment actually performs uplink data transmission, one of the effective information bit numbers corresponding to the uplink data may be selected according to an uplink service transmission requirement or according to other factors to perform uplink data transmission, unlike the prior art (UL grant-based transmission mode), which requires that the base station indicates the effective information bit number corresponding to the uplink data of the user equipment, for example, the TBS, through downlink control information. Therefore, when the ue selects the number of effective information bits corresponding to the uplink data by itself (i.e., one of the transmission schemes based on the UL grant free), the base station cannot know the number of effective information bits corresponding to the uplink data selected by the ue. Although the base station may determine the number of effective information bits corresponding to the uplink data selected by the ue in a blind detection manner, the complexity of the base station in determining the first resource is relatively high due to uncertainty of the number of effective information bits corresponding to the uplink data. By adopting the second mode, the base station can calculate the first resource through the preset information bit number corresponding to the uplink data, and then can decode the uplink control information according to the first resource, thereby reducing the processing complexity of the base station for acquiring the first resource.

Optionally, the uplink control information may include indication information, where the indication information is used to indicate a target information bit number of the uplink data. Therefore, the base station calculates the first resource through the preset information bit number corresponding to the row data to obtain the first resource, then decodes the uplink control information according to the first resource, and can determine the effective information bit number corresponding to the uplink data according to the indication information included in the uplink control information, so that the decoding process of the uplink data of the base station can be simplified, and the complexity of the base station processing is reduced.

The following illustrates a relationship between a preset information bit number corresponding to uplink data and an effective information bit number corresponding to the uplink data. The preset information bit number corresponding to the uplink data is only used for calculating the first resource, and when the user equipment actually performs uplink data transmission, the transmitted effective information bit number may be equal to the preset information bit number or may not be equal to the preset information bit number. For example, the set of valid information bits corresponding to the uplink data is: {1000 bits, 2000 bits, 3000 bits, 4000 bits }, that is, when the ue performs uplink data transmission, at least one effective information bit number corresponding to the uplink data may be selected from the set (when the uplink data is transmitted through at least 2 uplink codewords, the ue may select 1 or more effective information bit numbers corresponding to the uplink data from the set). In a second way, the preset information bit number may be configured to be 500 bits, or may be one of the above sets but preconfigured or predefined for the base station, such as 500 bits (the bit number does not change in a period of time). And the user equipment calculates to obtain the first resource according to the preset information bit number, the effective information bit number corresponding to the uplink control information and the capacity of the second physical uplink channel. Further optionally, assuming that the preset information corresponding to the uplink data is 500 bits, and the number of the effective information bits selected when the user equipment performs uplink data transmission is 2000 bits, the indication information included in the uplink control information may indicate that the number of the effective information corresponding to the uplink data is 2000 bits.

Thirdly, the user equipment determines the first resource according to the effective information bit number corresponding to the uplink control information, the effective information bit number corresponding to the uplink data and the preset resource corresponding to the uplink data.

The main difference between the third method and the first method is that one of the parameters used in calculating the first resource is replaced by "the capacity of the second physical uplink channel" to "the preset resource corresponding to the uplink data", and the description of the other parameters may refer to the description of the first method, which is not described herein again. In the embodiment of the present invention, if the first resource is represented by the number of modulation symbols, Q 'is replaced by Q'_symbIf the coded bit number is adopted for representation, Q is replaced by Q_bitWherein, Q'_symbAnd Q_bitAnd respectively representing preset resources corresponding to the uplink data represented by the number of modulation symbols and the number of coding bits. When the ue transmits uplink data, the effective resource (which can be understood as the second resource) corresponding to the uplink dataResources) may be different depending on the number of information bits of uplink data and different MCS, thereby achieving link adaptation. Therefore, in order to implement link adaptation for data transmission, the user equipment may select an effective resource corresponding to uplink data, that is, a second resource, by itself, but the first resource may be different according to the different selected second resource corresponding to the uplink data, in this case, the base station may only determine the effective resource corresponding to uplink data transmission by performing blind detection on the selected effective resource and determine the first resource, which may increase complexity of operation of the base station. In order to solve the above problem, in the embodiment of the present invention, the user equipment calculates the first resource according to the preset resource corresponding to the uplink data, and sends the uplink control information to the base station through the physical uplink channel according to the first resource, so that the base station can calculate the first resource according to the preset resource corresponding to the uplink data and obtain the uplink control information, which is convenient for the operation of the base station. Optionally, the uplink control information may include indication information, where the indication information is used to indicate a physical uplink channel capacity used by the user equipment for transmitting uplink data and/or uplink control information. Optionally, the uplink control information may include indication information, where the indication information is used to indicate the second resource corresponding to the uplink data.

It should be noted that, in this embodiment of the present invention, the preset resource corresponding to the uplink data is only used to calculate the first resource, and when the user equipment actually performs uplink data transmission, an effective resource (for example, the second resource) corresponding to the uplink data or a capacity of a second physical uplink channel including uplink data transmission or a capacity of a physical uplink channel including uplink data and uplink control information transmission (which may be represented by the first physical uplink channel or may be represented by the second physical uplink channel) may be equal to the preset resource corresponding to the uplink data, or may not be equal to the preset resource corresponding to the uplink data.

Fourthly, the user equipment determines the first resource according to the effective information bit number corresponding to the uplink control information, the preset information bit number corresponding to the uplink data and the preset resource corresponding to the uplink data.

For this embodiment, please refer to the detailed description of the second and third embodiments, which is not repeated herein.

Fifthly, the first resource is a pre-configured resource corresponding to the uplink control information or a pre-defined resource corresponding to the uplink control information.

Specifically, the first resource may be directly preconfigured by the base station or the pre-defining may be implemented by higher layer signaling, such as RRC signaling or MAC signaling, and the pre-defining includes setting a fixed resource value.

Sixthly, the first resource may be further determined according to a preset information bit number of the uplink control information and an MCS corresponding to the uplink control information, where the preset information bit number of the uplink control information may be preconfigured or predefined, and the MCS corresponding to the uplink control information may be preconfigured or predefined.

In the embodiment of the present invention, when the physical uplink channel for transmitting the uplink control information is the same as the physical uplink channel for transmitting the uplink data, the second resource may be a capacity corresponding to the physical uplink channel, or may be a capacity remaining after the capacity of the physical uplink channel is removed from the capacity of the first resource; or, when the physical uplink channel for transmitting the uplink control information is the same as the physical uplink channel for transmitting the uplink data, the second resource may be the capacity of the second physical uplink channel, or the capacity of the second physical uplink channel remaining after the first resource is removed from the capacity of the second physical uplink channel. When the physical uplink channel for transmitting the uplink control information is different from the physical uplink channel for transmitting the uplink data, the second resource may be a capacity of the physical uplink channel for transmitting the uplink data, or the second resource is a capacity of the second physical uplink channel.

It should be noted that, in this embodiment of the present invention, the physical uplink channel capacity (including the capacity of the first physical uplink channel or the capacity of the second physical uplink channel) may refer to a remaining capacity after the number of modulation symbols or the number of coding bits or the number of Resource Elements (REs) occupied by the uplink reference signal, for example, the DMRS or the sounding reference signal, for example, the SRS, is removed from the physical uplink channel capacity. Or more generally, may refer to a remaining capacity after removing a capacity occupied by an important signal (e.g., a reference signal) and an important uplink transport channel from the physical uplink channel capacity. Optionally, if the uplink data includes uplink service data and an uplink reference signal, the physical uplink channel capacity (including the capacity of the first physical uplink channel or the capacity of the second physical uplink channel) may not exclude the number of modulation symbols occupied by the uplink reference signal, for example, the DMRS or the SRS, or the number of occupied REs.

In the embodiment of the present invention, no matter the number of bits of the effective information corresponding to the uplink data or the number of bits of the effective information corresponding to the uplink control information, the number of preconfigured values may be 1 or multiple, which is not specifically limited in the embodiment of the present invention.

Optionally, the second resource is obtained by calculating according to a target information bit number and an MCS corresponding to the uplink data; or, the second resource is a pre-configured resource corresponding to the uplink data or a pre-defined resource corresponding to the uplink data. Optionally, the uplink control information includes second indication information, and the second indication information indicates the second resource.

Optionally, the second resource may be determined in three ways: the first resource is obtained by calculating according to a target information bit number corresponding to uplink data and an MCS (modulation and coding scheme), wherein the target information bit number corresponding to the uplink data comprises an effective information bit number corresponding to the uplink data or a preset information bit number corresponding to the uplink data, and the preset information bit number corresponding to the uplink data and the MCS can be preconfigured; second, the second resource may be determined pre-configured or pre-defined; third, the second resource is determined by second indication information in the uplink control information.

In the embodiment of the present invention, the control information included in the uplink control information refers to information indicated by a bit combination or information indicated by a single bit included in the uplink control information.

S203, the user equipment performs first preprocessing on the uplink control information according to the first resource.

Specifically, the ue performs a first pre-processing on the uplink control information according to the first resource. The first preprocessing may include at least one of sequence modulation, channel coding, and rate matching, and may also include other processing manners, such as channel interleaving, constellation modulation, resource mapping, and precoding, that are used for the base station to obtain corresponding information according to the received uplink data, except for sequence modulation, channel coding, and rate matching.

For the first preprocessing, taking channel coding as an example, the first resource is assumed to be the number of modulation symbols Q'_CIAnd the user equipment is according to Q'_CIModulation order Q corresponding to uplink control information_mThe number of encoding bits Q of the uplink control information can be calculated_CISpecifically, Q_CI＝Q′_CI*Q_m. The user equipment carries out channel coding on the uplink control information according to the calculated coding bit number and the effective information bit number corresponding to the uplink control information to obtain an uplink control information coding bit stream

For the first preprocessing, taking sequence modulation as an example, the ue may load the number of effective information bits corresponding to the uplink control information on the reference sequence or the reference signal according to the reference sequence or the reference signal. Optionally, the user equipment may select a sequence corresponding to the combination of the uplink control information according to different combinations of the effective information bit numbers of the uplink control information, for example, if the target information bit number of the uplink control information is 3, the effective information bits have 8 different combination modes, and may respectively correspond to 8 different sequences, as shown in table 2. Table 2 is a mapping table of valid information bit combinations and sequences of uplink control information,

in this way, the ue obtains the first resource occupied by the uplink control information, and one understanding is that the ue obtains a sequence corresponding to a valid information bit combination of the uplink control information, and obtains sequences corresponding to all possible combinations of valid information bits of the uplink control information, i.e. sequence 1 to sequence 8, taking table 2 as an example. Further, the ue performs a first pre-processing on the uplink control information according to the first resource, which may be understood as that the ue determines a sequence according to an effective information bit combination of the uplink control information to be transmitted. For example, still taking table 2 as an example, assuming that the valid information bit combination transmitted by the ue in a certain time unit is 011, the ue obtains a sequence 4 corresponding to the valid information bit combination of the uplink control information. At this time, the ue transmits the preprocessed uplink control information through the first physical uplink channel, which can be understood as that the ue transmits the sequence 4 through the first physical uplink channel. Optionally, the first physical uplink channel may be represented by a physical uplink resource, such as an RE or an RB, carrying sequence 4 transmission. In addition, in this manner, the ue obtains the first resource occupied by the uplink control information, and another understanding is that the ue obtains a sequence corresponding to the valid information bit combination of the uplink control information to be transmitted, for example, still taking table 2 as an example, assuming that the valid information bit combination transmitted by the ue in a certain time unit is 011, the ue obtains a sequence 4 corresponding to the valid information bit combination of the uplink control information. Further, the ue performs a first pre-processing on the uplink control information according to the first resource, which may be understood that the ue determines that a sequence to be sent is sequence 4. At this time, the ue transmits the preprocessed uplink control information through the first physical uplink channel, which may be understood as that the ue transmits the sequence 4 through the first physical uplink channel, and it should be noted that, optionally, the first physical uplink channel may be represented by physical uplink resources, such as REs or RBs, transmitted by the bearer sequence 4.

Optionally, assuming that the number of effective information bits of the uplink control information is M, the total number of the effective information bits is 2^MDifferent combination modes can respectively correspond to 2^MA different sequence.

Optionally, when the first preprocessing is sequence modulation, the first preprocessing may also be that the user equipment modulates the number of effective information bits corresponding to the uplink control information to obtain a modulation symbol, and then loads the modulation symbol on a sequence, where the sequence may be preconfigured or predefined. In this way, the ue obtains the first resource occupied by the uplink control information, which may be understood as a sequence used by the ue to obtain and transmit the uplink control information. Further optionally, the user equipment performs first preprocessing on the uplink control information according to the first resource, which may be understood as that the user equipment modulates effective information bits corresponding to the uplink control information to obtain a modulation symbol, and then processes the modulation symbol according to the determined sequence, for example, multiplies the modulation symbol by the determined sequence, or uses another method. The user equipment transmits the first preprocessed uplink control information to the base station through the first physical uplink channel, which can be understood as that the user equipment transmits the sequence carrying the modulation symbol information through the first physical uplink channel.

Table 2 mapping relationship between effective information bit combination and sequence of uplink control information

Optionally, after channel coding is performed on the effective information bit number corresponding to the uplink control information to be transmitted, if the coding bit number obtained after the channel coding is not matched with the first resource, rate matching needs to be performed on the coding bit number after the channel coding, so that the coding bit number after the channel coding is matched with the first resource. The mismatch here means that the number of coded bits obtained after channel coding is not equal to the number of coded bits represented by the first resource. When the first resource is the number of modulation symbols, the number of coded bits represented by the first resource may be understood as the number of modulation orders multiplied by the first resource. For example, assuming that the number of information bits to be transmitted is 10, using channel coding with 1/3 coding rate, the number of coding bits obtained after channel coding is 30, and meanwhile, assuming that the number of first resources is 20 and the number of modulation symbols is 20, the corresponding modulation scheme is QPSK, that is, the corresponding modulation order is 2, the number of coding bits corresponding to the first resource is 40, and obviously, the number of coding bits (30) after channel coding does not match the number of coding bits (40) represented by the first resource, at this time, it is necessary to perform rate matching on the number of coding bits after channel coding so that the number of coding bits matches the number of coding bits represented by the first resource. The description is also applicable to the description of the effective information bit number corresponding to the uplink data.

It should be noted that, in this embodiment of the present invention, optionally, the rate matching further indicates that, when the uplink control information is transmitted through the first physical uplink channel, the uplink control information is transmitted by using only a part of resources in the first physical uplink channel, and other resources in the first physical uplink channel are used for transmitting reference signals, such as DMRS and SRS.

Optionally, the first preprocessing includes a process of adapting the effective information bit number corresponding to the uplink control information to the first resource, where the adaptation may indicate that the effective information bit number corresponding to the uplink control information is subjected to the first preprocessing, and the obtained bit number after the first preprocessing is equal to the coding bit number indicated by the first resource.

In this embodiment of the present invention, no matter whether the first preprocessing, the second preprocessing, or the third preprocessing is performed, when the preprocessing includes channel coding, a specific channel coding manner may use Reed-Muller RM (32, O) (O represents an input encoder bit length), or a dual Reed-Muller RM (32, O) code or a tail-biting convolutional code tbcc (tail-biting convolution code), or a Polar code (Polar code), or a Turbo code, or other channel coding, which is not specifically limited in this embodiment of the present invention.

And S204, the user equipment transmits the first preprocessed uplink control information to the base station through a first physical uplink channel.

Specifically, the uplink control information after the first preprocessing may be further processed by at least one of following processes (e.g., scrambling, modulation, Discrete Fourier Transform (DFT), resource mapping, Inverse DFT (IDFT), etc.), and then transmitted to the base station through the first physical uplink channel. For a detailed explanation of the first physical uplink channel and the uplink control information after the first preprocessing, please refer to the detailed descriptions of S202 to S203, which are not described herein again. After receiving the first preprocessed uplink control information, the base station may perform inverse processing on the preprocessed uplink control information (that is, an inverse process of the preprocessing may include at least one of channel decoding, and rate matching), for example, when the preprocessing mode adopted by the user equipment is channel coding, the base station adopts the inverse processing mode to decode the channel, so as to recover the uplink control information.

Optionally, the user equipment performs channel coding and/or rate matching on the uplink control information according to the first resource to obtain a coded bit stream of the uplink control information, and transmits the coded bit stream of the uplink control information to the base station through a first physical uplink channel.

Optionally, steps S203 and S204 may also be replaced by:

the user equipment performs channel coding and/or rate matching on the uplink control information according to the first resource to obtain a coded bit stream of the uplink control information, and transmits the coded bit stream of the uplink control information to a base station through a first physical uplink channel. "

S205, the user equipment performs second preprocessing on the uplink data according to the second resource.

Specifically, the ue performs a second preprocessing on the uplink control information according to the second resource. The second preprocessing may include at least one of sequence modulation, channel coding, and rate matching, and may also include other processing manners, such as channel interleaving, constellation modulation, resource mapping, and precoding, that are used for the base station to obtain corresponding information according to the received uplink data, except for sequence modulation, channel coding, and rate matching.

For the second preprocessing, taking channel coding as an example, the second resource is assumed to be the number of modulation symbols Q'_UL-SCHAnd the user equipment is according to Q'_UL-SCHModulation order Q 'corresponding to uplink control information'_mThe number of encoding bits Q of the uplink control information can be calculated_UL-SCHSpecifically, Q_UL-SCH＝Q′_UL-SCH*Q′_m. The user equipment carries out channel coding on the uplink control information according to the calculated coding bit number and the information bit number of the uplink control information to obtain an uplink control information coding bit stream

When the second preprocessing corresponds to sequence modulation or rate matching, please refer to the detailed explanation of the first preprocessing in step S203 for partial description and explanation of the second preprocessing, which only needs to replace the first preprocessing with the second preprocessing and replace the uplink control information with the uplink data, which is not described herein again.

And S206, the user equipment transmits the second preprocessed uplink data to the base station through a second physical uplink channel.

Specifically, the uplink control information after the second preprocessing may be further processed by at least one of the following processes (e.g., scrambling, modulation, Discrete Fourier Transform (DFT), resource mapping, Inverse DFT (IDFT), etc.), and then transmitted to the base station through the second physical uplink channel. For a detailed explanation of the second physical uplink channel and the uplink control information after the second preprocessing, please refer to the detailed descriptions of S202 to S203, which are not described herein again. After receiving the second preprocessed uplink data, the base station may perform inverse processing on the second preprocessed uplink data (that is, an inverse process of the preprocessing may include at least one of channel decoding, and rate matching), for example, when the preprocessing mode adopted by the user equipment is channel coding, the base station adopts the inverse processing mode to perform channel decoding, so as to recover the uplink data.

Optionally, the user equipment performs channel coding and/or rate matching on the uplink data according to the second resource to obtain a coded bit stream of the uplink data, and transmits the coded bit stream of the uplink data to the base station through a second physical uplink channel.
