Description

Uplink information transmission method and device

[ technical field ] A method for producing a semiconductor device

The present invention relates to the field of communications technologies, and in particular, to the field of uplink information transmission technologies.

[ background of the invention ]

Unlicensed spectrum is a nationally and regionally divided spectrum that may be used for communication by radio devices, and is generally considered a shared spectrum, i.e., a spectrum that may be used by communication devices in different communication systems as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum license to be applied to the government. With the development of wireless communication technology, LTE (Long Term Evolution) systems and NR (New Radio) systems consider network deployment on unlicensed spectrum, so as to transmit data services by using the unlicensed spectrum.

In order for various communication systems using unlicensed spectrum to be able to coexist friendly on the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, the communication device follows the principle of "Listen Before Talk (LBT)", that is, before the communication device performs signal transmission on the channel of the unlicensed spectrum, it needs to perform channel sensing first, and only when the channel sensing result is that the channel is idle, the communication device can perform signal transmission; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot transmit signals.

In the above process, if the UE fails to perform HARQ-ACK feedback due to LBT failure, the UE can only wait for the next scheduling of the network device to perform HARQ-ACK feedback, and the waiting time delay is large. Similarly, if periodic or aperiodic CSI is reported, the UE cannot report because of LBT failure, and can only wait for the next reporting opportunity, and the time delay for reporting waiting is large.

[ summary of the invention ]

The invention provides an uplink information transmission method and device capable of reducing the reporting waiting time delay of user equipment.

The invention provides the following technical scheme:

an uplink information transmission method is applied to user equipment and comprises the following steps: an uplink transmission method applied to a User Equipment (UE), the method comprising: mapping target uplink control information to a Physical Uplink Shared Channel (PUSCH), wherein the target uplink control information comprises first uplink control information, and first indication information in the first uplink control information is used for determining whether the PUSCH comprises second uplink control information; and sending the PUSCH through a pre-configured authorized uplink resource.

An uplink transmission method is applied to a network device, and comprises the following steps: receiving a Physical Uplink Shared Channel (PUSCH) sent by user equipment through a pre-configured authorized uplink resource; the PUSCH comprises target uplink control information mapped by the user equipment; the target uplink control information comprises first uplink control information, and first indication information in the first uplink control information is used for determining whether the PUSCH comprises second uplink control information.

An uplink transmission device, comprising: a mapping unit, configured to map target uplink control information onto a physical uplink shared channel PUSCH, where the target uplink control information includes first uplink control information, and first indication information in the first uplink control information is used to determine whether the PUSCH includes second uplink control information; and the transmission unit sends the PUSCH by pre-configuring the authorized uplink resource.

An uplink transmission device comprises a receiving unit, a transmitting unit and a receiving unit, wherein the receiving unit is used for receiving a Physical Uplink Shared Channel (PUSCH) sent by user equipment through a pre-configured authorized uplink resource; the PUSCH comprises target uplink control information mapped by the user equipment; the target uplink control information comprises first uplink control information, and first indication information in the first uplink control information is used for determining whether the PUSCH comprises second uplink control information.

An uplink information transmission apparatus, comprising: a processor, a memory, and a network interface; the processor calls the program in the memory, executes the implementation mode of any uplink transmission method, and sends out the execution result through the network interface.

A computer-readable storage medium, wherein the computer-readable storage medium has stored thereon a program for uplink information transmission, which when executed by a processor implements an embodiment of executing any one of the uplink transmission methods.

The invention has the beneficial effects that: in an embodiment of the application, a user equipment maps target uplink control information to a PUSCH, and then grants an uplink resource to send the PUSCH through pre-configuration, wherein the target uplink control information includes first uplink control information, and the network equipment is notified whether the PUSCH includes second uplink control information or not through first indication information in the first uplink control information. Therefore, the uplink control information for downlink transmission is actively reported to the network equipment by the user equipment without being fed back based on the scheduling of the network equipment, so that the waiting time delay for reporting the UCI of the user equipment is reduced or shortened.

The following embodiments of the present application will explain in detail how the user equipment uses CG-PUSCH to report UCI information to the network equipment.

Implementation mode one

Please refer to fig. 2, which is a method for transmitting uplink information according to an embodiment of the present application, the method includes:

step S210, a user equipment maps target uplink control information to a Physical Uplink Shared Channel (PUSCH), the PUSCH authorizes uplink resource transmission through pre-configuration, the target uplink control information comprises first uplink control information, and first indication information in the first uplink control information is used for determining whether the PUSCH comprises second uplink control information;

step S220, the user equipment sends the PUSCH to the network equipment through the preconfigured authorized uplink resource.

Optionally, the first uplink control information and the second uplink control information are different. Optionally, the first uplink control information includes control information for demodulating the PUSCH, and the second uplink control information includes uplink control information for downlink transmission, for example: feedback information of a downlink channel, channel quality information of a downlink channel, and the like. Optionally, the difference means that the first uplink control information and the second uplink control information are independently channel-coded. Specifically, the first uplink control information may be CG-UCI, and is used to demodulate the PUSCH. However, the first uplink control information is not limited to demodulation of the PUSCH, and may be used for demodulation of other control information. For example, if the PUSCH includes uplink data, the CG-UCI includes control information for demodulating the uplink data; and/or, if other UCIs except the CG-UCI are included in the PUSCH, the CG-UCI includes control information for demodulating the other UCIs.

Specifically, the second uplink control information is UCI other than CG-UCI. The CG-UCI is used to indicate whether other UCI than CG-UCI is included in the PUSCH, i.e., the user equipment notifies the network equipment through the CG-UCI whether it has transmitted other UCI than CG-UCI to the network equipment.

Optionally, the second uplink control information is other uplink control information different from the first uplink control information, for example: and when the first uplink control information is CG-UCI, the second uplink control information is other UCI except the CG-UCI. Another example is: the first indication information comprises 1 bit, wherein the 1 bit is used for indicating that no other type of UCI except CG-UCI is carried on the pre-configured authorized uplink resource CG-PUSCH, or the 1 bit is used for indicating that the other type of UCI except CG-UCI is carried on the CG-PUSCH.

Optionally, the second uplink control information includes at least one of HARQ information and CSI. Optionally, the CSI includes at least one of a first partial channel state information CSI Part 1 and a second partial channel state information CSI Part 2.

Alternatively, the user equipment may decide to need to feed back information to the network equipment. The first indication information is specifically used to indicate whether the PUSCH includes the second uplink control information that the UE determines to transmit. As an example, the first indication information may indicate one of the following states: the PUSCH comprises the HARQ information, and the PUSCH does not comprise the HARQ information.

It should be understood that when the user equipment determines to transmit the PUSCH through the preconfigured authorized uplink resource, if the preconfigured authorized uplink resource and the uplink resource used by the user equipment for transmitting the physical uplink control channel PUCCH at least partially overlap in the time domain, the user equipment may carry Part or all of the uplink control information (e.g., HARQ information, CSI Part 1, CSI Part 2, and the like) to be transmitted in the PUCCH on the PUSCH for transmission. Since the HARQ information reflects the downlink scheduling condition of the network device (e.g., decoding corresponding to the PDSCH), HARQ information feedback is only required when downlink scheduling occurs. In addition, on the unlicensed spectrum, the network device may also use the trigger information to trigger the ue to perform HARQ information feedback, for example, to trigger the ue to perform HARQ feedback based on the PDSCH channel group or feedback based on the full codebook. When the network device sends a PDCCH for scheduling a PDSCH to the user equipment, or when the network device sends a trigger signaling to the user equipment to trigger the user equipment to perform HARQ feedback, if the user equipment does not correctly receive the PDCCH or the trigger signaling, the user equipment does not feed back HARQ information, but the network device expects the user equipment to feed back HARQ information. The user equipment and the network equipment have inconsistent understanding on whether the HARQ information needs to be transmitted, which may cause inconsistent understanding of rate matching, thereby affecting the demodulation performance of the network equipment. Therefore, optionally, the first indication information is used to indicate whether HARQ information is included in the PUSCH. The first indication information may indicate one of the following states: the PUSCH comprises the HARQ information, and the PUSCH does not comprise the HARQ information. In this embodiment, the ue indicates whether the ue itself transmits HARQ-ACK information in the first indication information in the first control information, so that the network device can perform correct rate matching according to the first indication information.

Optionally, the first embodiment of the present application may include at least one of the following cases:

situation one

The target uplink control information comprises the HARQ information, and the first indication information indicates that the PUSCH comprises the HARQ information. Optionally, the first indication information is used to indicate one of the following states: the PUSCH comprises the HARQ information, and the PUSCH does not comprise the HARQ information.

Optionally, the first uplink control information further includes second indication information, where the second indication information is used to indicate at least one of the following information: the feedback type of the HARQ information comprises at least one of dynamic codebook feedback, single trigger codebook feedback and semi-static codebook feedback; the number of information bits of the HARQ information; the number of resources occupied by the HARQ information; a channel group identifier corresponding to the HARQ information; the total number of downlink allocation indicators (T-DAI) corresponding to the channel group; new feedback group indication information NFI corresponding to the channel group; a carrier identifier corresponding to the HARQ information; a process number or a process number group corresponding to the HARQ information; the new data indication NDI corresponding to the process number; and the HARQ feedback window corresponds to the HARQ information.

Optionally, the feedback type of the HARQ information is dynamic codebook feedback, and a codebook corresponding to the HARQ information is determined according to at least one of the following: a channel group identifier to be fed back, a downlink allocation indication count (C-DAI) corresponding to the channel group, a T-DAI corresponding to the channel group, an NFI corresponding to the channel group, and a carrier identifier corresponding to the HARQ information.

Optionally, the codebooks corresponding to the HARQ information are sequentially arranged according to the C-DAI in the channel group to be fed back.

For example, referring to fig. 3, in a first transmission opportunity, the ue receives a PDSCH transmitted by the network device, and is expected to feed back three HARQ information corresponding to channel group 0 on PUCCH 0, but due to LBT failure, the ue fails to feed back three HARQ information corresponding to channel group 0 on PUCCH 0. In the second transmission opportunity, the ue receives the PDSCH transmitted by the network device again, and is expected to feed back three HARQ information corresponding to channel group 0 and two HARQ information corresponding to channel group 1 on PUCCH 1, however, due to LBT failure, the ue cannot feed back HARQ information corresponding to channel group 0 and channel group 1 on PUCCH 1. There is a CG-PUSCH resource after the PUCCH 1, and if the user equipment obtains the channel usage right of the CG-PUSCH resource, the user equipment can feed back HARQ information corresponding to channel group 0 and channel group 1 to the network equipment through the CG-PUSCH resource. The first indication information includes indication information that the feedback group 0, the total number of DAIs in the feedback group 0 is 3, the NFI value of the feedback group 0 is 1, the feedback group 1, the total number of DAIs in the feedback group 1 is 2, and the NFI value of the feedback group 1 is 0. Accordingly, the codebook based on the C-DAI ordering fed back by the user equipment on the CG-PUSCH is shown in the following table 1. The codebook order shown in Table 1 is arranged in order of first-to-first left and last-to-last:

TABLE 1

Optionally, the feedback type of the HARQ information is dynamic codebook feedback, the channel group to be fed back includes all channel groups corresponding to the PDSCH received by the user equipment, and the codebook corresponding to the HARQ information is determined according to at least one of the following: a process number or a process number group corresponding to the HARQ information, NFI corresponding to the channel group, and a carrier identifier corresponding to the HARQ information.

Optionally, the codebooks corresponding to the HARQ information are arranged in sequence according to all HARQ process numbers.

For example, continuing to refer to fig. 3, the user equipment fails to feed back HARQ information on PUCCH 0 in both the first transmission opportunity and the second transmission opportunity. But after obtaining the channel use weight of a CG-PUSCH resource, HARQ information to the network equipment through the CG-PUSCH resource. The first indication information includes indication information for feeding back all groups, indication information for which the NFI value of group 0 is 1 and indication information for which the NFI value of group 1 is 0. Accordingly, the codebook based on the HARQ process number order fed back by the user equipment on the CG-PUSCH is shown in table 2 below. The codebook order shown in table 2 is first and last from the left of each row; then, the first row on the top is the first, and the last row is arranged in the last order:

TABLE 2

Optionally, the feedback type of the HARQ information is single-trigger codebook feedback, and a codebook corresponding to the HARQ information is determined according to at least one of the following: the carrier identifier corresponding to the HARQ information, the process number or the process number group corresponding to the HARQ information, and the NDI corresponding to the process number.

Optionally, the codebooks corresponding to the HARQ information are arranged in sequence according to all HARQ process numbers. Optionally, the second uplink control information includes, in addition to the HARQ information corresponding to all HARQ process numbers, also the NDI corresponding to all HARQ process numbers.

For example, please continue to refer to fig. 3, similarly, when the ue fails to feed back HARQ information on PUCCH 0 in both the first transmission opportunity and the second transmission opportunity. And then obtaining the channel use weight of a CG-PUSCH resource, and HARQ information to the network equipment through the CG-PUSCH resource. The third indication information comprises indication information fed back by the full codebook HARQ-ACK and indication information of corresponding carrier identification information. Accordingly, the codebook based on the HARQ process number order fed back by the user equipment on the CG-PUSCH is as shown in table 3 or 4 below. In table 3, the NDI information of all HARQ processes is fed back first, and then the HARQ information of all HARQ processes is fed back. In table 4, the NDI information and HARQ information of each HARQ process are cascade-fed. The codebook order shown in tables 3 and 4 is first and last from the left of each row, and last; then, the first row on the top is the first, and the last row is arranged in the last order:

TABLE 3

TABLE 4

Optionally, the feedback type of the HARQ information is semi-static codebook feedback, and a codebook corresponding to the HARQ information is determined according to at least one of the following: and the carrier identifier corresponding to the HARQ information and the HARQ feedback window corresponding to the HARQ information.

Optionally, the codebooks corresponding to the HARQ information are sequentially arranged according to the HARQ feedback windows. The network equipment configures a K1set (K1set) and a time domain resource allocation table for the terminal equipment through protocol predefinition or high-level signaling, the terminal equipment determines the candidate time domain position of the PDSCH according to the time domain resource allocation table, and determines the time slot in which the feedback information of the PDSCH is possible according to the candidate time domain position of the PDSCH and the K1 set. The time slot in which the feedback information of the PDSCH may be located is referred to as a HARQ feedback window. In each uplink time slot, the terminal equipment determines a PDSCH opportunity set associated with the uplink time slot according to the candidate time domain position of the PDSCH and the K1set, namely the associated downlink time slot and the PDSCH opportunity set in the downlink time slot, and then generates a feedback codebook according to the associated PDSCH opportunity set.

The UCI type for transmission on the pre-configured granted uplink resource (e.g., CG-PUSCH) may include at least one of: CG-UCI, HARQ-ACK, CSI Part 1 and CSI Part 2. In order to ensure the reliability of UCI transmitted on CG-PUSCH, a rate compensation factor may be defined for UCI information, that is, more REs (resource elements) may be allocated to UCI with the same bit.

Optionally, in order to ensure the reliability of transmitting the UCI on the CG-PUSCH, a rate compensation factor may be defined for the UCI information, that is, more RE resources may be allocated to the UCI with the same bit, which improves the transmission reliability of the UCI by reducing the UCI rate.

Optionally, if the downlink control signaling DCI activating the CG-PUSCH includes a code rate compensation factor indicator field, the code rate compensation factor may configure a set for the user equipment through a high-level signaling semi-statically, and then dynamically indicate to the user equipment through the DCI.

Optionally, if the DCI signaling activating the CG-PUSCH does not include the code rate compensation factor indicator field, or the CG-PUSCH does not require DCI activation, the code rate compensation factor is a parameter β of a higher layer configuration, the UCI.

For the case that CG-PUSCH carries uplink data, a parameter (alpha) configured by a high-level signaling can be introduced for the transmission of the UCI information^{First UCI}) This parameter is used to limit the upper limit of the number of occupied REs of the UCI information.

For the case that no uplink data is carried on CG-PUSCH, the number of RE resources occupied by UCI may be calculated by at least one of the total bit number of UCI information, a reference code rate, a modulation order, and a code rate compensation factor β the UCI, and the like. The reference code rate and the modulation order may be configured by high layer signaling semi-statically or may be indicated by DCI signaling activating CG-PUSCH.

Optionally, if the UCI is not CG-UCI, the rate compensation factor β first UCI and/or the resource restriction parameter α first UCI of the UCI may be further obtained by: taking the code rate compensation factor as an example, the network device configures a code rate compensation factor set for the terminal device through a high-level signaling semi-static state, the terminal device selects the code rate compensation factor from the code rate compensation factor set, and reports the selected code rate compensation factor to the network device, for example, the terminal device reports the selected code rate compensation factor to the network device through CG-UCI.

Optionally, if the UCI is not CG-UCI, the terminal device may report the total bit number of the UCI, the number of occupied resources, and/or the location of occupied resources (e.g., symbol location or RB/RE location) to the network device. For example, the terminal device reports the total bit number of the UCI (total bit number after coding), the number of occupied resources, and/or the position of occupied resources to the network device through the CG-UCI.

In an embodiment of the present application, a user equipment maps target uplink control information to a PUSCH, and then grants an uplink resource to send the PUSCH through pre-configuration, where the target uplink control information includes first uplink control information, and notifies, through first indication information in the first uplink control information, to a network device whether the PUSCH includes second uplink control information, so that the user equipment actively reports uplink control information for downlink transmission to the network device, for example: for example, feedback information of a downlink channel or channel quality information of the downlink channel, etc., and uplink control information of the network device does not need to be fed back based on scheduling of the network device, thereby reducing or shortening waiting time delay reported by the UCI of the user equipment.
