Description

CSI processing method, processing device and UE

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a CSI processing method, a processing device and UE.

Background

In the related art, a User Equipment (UE) may measure a state of a channel and report a measurement result, that is, Channel State Information (CSI).

Generally, the UE needs to periodically send periodic CSI (periodic CSI, P-CSI) and semi-static CSI (SP-CSI), and once the network device configures or activates the UE to report CSI periodically, the UE needs to measure and report CSI in each reporting period. For example, in broadcast/multicast service transmission, the network device may configure the same CSI measurement information (e.g., CSI measurement reference signals and CSI measurement periods) for a plurality of UEs, and after the plurality of UEs report CSI in each reporting period, the network device may determine how to schedule the broadcast/multicast service according to the CSI reported by the plurality of UEs and then according to the CSI reported by the plurality of UEs (e.g., according to the UEs with poor channel quality).

However, in the above process, since a plurality of UEs all need to report CSI in each reporting period, and when the network device schedules the broadcast/multicast service, it only needs to schedule according to the UE with poor channel quality, which results in waste of UE uplink resources and UE transmission power.

Disclosure of Invention

The embodiment of the invention provides a CSI processing method, a processing device and UE, which can solve the problem that UE uplink resources and UE transmitting power are wasted in the process of reporting CSI by the UE.

In order to achieve the purpose, the embodiment of the invention adopts the following technical scheme:

in a first aspect of the embodiments of the present invention, a CSI processing method is provided, which is applied to a UE, and includes: acquiring first information, wherein the first information represents a decoding result of downlink transmission in a first time period or represents a measurement result of CSI in a first reporting period, and the end position of the first time period is at least no later than the initial position of a reporting resource of the CSI in the first reporting period; and determining the CSI processing mode in the first reporting period according to the first information.

In a second aspect of the embodiments of the present invention, there is provided a processing apparatus, which may include: the device comprises an acquisition module and a determination module; the obtaining module is configured to obtain first information, where the first information represents a decoding result of downlink transmission in a first time period or represents a measurement result of CSI in a first reporting period, and an end position of the first time period is at least no later than a start position of a reporting resource of the CSI in the first reporting period; the determining module is configured to determine, according to the first information acquired by the acquiring module, a CSI processing mode in a first reporting period.

In a third aspect of the embodiments of the present invention, a UE is provided, where the UE includes a processor, a memory, and a computer program stored in the memory and executable on the processor, and the computer program, when executed by the processor, implements the steps of the CSI processing method in the first aspect.

In a fourth aspect of the embodiments of the present invention, a computer-readable storage medium is provided, on which a computer program is stored, which when executed by a processor implements the steps of the CSI processing method according to the first aspect.

In the embodiment of the present invention, the UE may obtain the first information, and then determine, according to the first information, a CSI processing manner in the first reporting period. Since the first information may represent a decoding result of downlink transmission in the first time period or represent a measurement result of CSI in the first reporting period, an end position of the first time period is at least no later than a start position of a reporting resource of the CSI in the first reporting period. That is, before reporting the CSI in the first reporting period, the UE may determine, according to a decoding result of downlink transmission in the first time period, a CSI processing manner in the first reporting period, report the CSI in the first reporting period, or abandon reporting the CSI in the first reporting period; in the embodiment of the present invention, the UE may first determine whether the UE needs to report the CSI in one reporting period, abandon reporting the CSI, and abandon measurement according to the first information, and then the UE may process the CSI according to the processing method of the CSI in the reporting period determined by the first information, so that the consumption of the UE measurement and the uplink feedback power may be saved without reporting the CSI or abandoning measuring the CSI. Under the condition that the network equipment configures the same CSI feedback resources for a plurality of UEs, part of the UEs can be free from reporting the CSI, and under the condition that resource conflict is controllable, the expense of the network equipment for receiving the CSI feedback resources can be saved.

The following explains some concepts and/or terms involved in the CSI processing method and apparatus provided in the embodiments of the present invention.

1. Broadcast/multicast service

Compared with the previous mobile communication systems, future mobile communication systems need to adapt to more diversified scenes and service requirements. The main scenarios of NR include enhanced mobile broadband (eMBB), massive machine type communications (mtc), and ultra-reliable and low latency communications (URLLC), which impose different requirements on the system in terms of high reliability, low latency, large bandwidth, wide coverage, and the like.

Currently, New Radio (NR) technology has undergone evolution through two versions, Rel-15 and Rel-16, in which broadcast/multicast (broadcast/multicast) features are not supported, but in many important usage scenarios, system efficiency and user experience can be substantially improved if the broadcast/multicast features are supported. For example, in the scenarios of public safety and mission critical (public safety and mission critical), V2X applications (V2X applications), transparent IPv4/IPv6 multicast delivery (transparent IPv4/IPv6 multicast delivery), interactive network television IPTV, wireless software delivery (software delivery over wireless), group communication and internet of things applications (group communications and IoT applications), and so on.

2. Broadcast/multicast traffic in Long Term Evolution (LTE)

In LTE broadcast multicast transmission, Multimedia Broadcast Multicast Service (MBMS) service transmission and single-cell-to-multipoint (sc-ptm) multicast service transmission are supported in a multimedia broadcast multicast service single frequency network (MBSFN) manner. In the MBSFN scheme, cells in the same MBSFN area may synchronously transmit the same broadcast service, so that the UE can receive the broadcast service conveniently. The network equipment sends the control information (control channel parameter and service channel parameter, scheduling information, etc.) and data information of the MBMS service in a broadcast mode, so that idle state (idle state) UE and connected state UE can both receive the MBMS service. The data information of the MBMS is only transmitted in the MBSFN subframe. The sc-ptm scheme is a multicast transmission scheme standardized after the MBMS service, and the sc-ptm scheme is the biggest difference from the MBSFN scheme in that the transmission is scheduled only in a single cell, and the service scheduling is performed by g-rnti (group rnti). And broadcasting control channel parameters, service identifiers, period information and the like in the broadcast message, wherein the scheduling information is notified by the PDCCH scrambled by the g-RNTI, and the data part is transmitted in a multicast mode, which is equivalent to that interested UE monitors the g-RNTI to obtain data scheduling and then receives the data scheduling.

3. CSI in NR

To meet different requirements, the NR system designs different types of CSI reports in 4: an aperiodic CSI report (a-CSI), a semi-static CSI report on PUSCH (SP-CSI on PUSCH) carried on a Physical Uplink Shared Channel (PUSCH), a semi-static CSI report on PUCCH (SP-CSI on PUCCH) carried on a Physical Uplink Control Channel (PUCCH), a periodic CSI report (P-CSI).

The a-CSI and the SP-CSI on PUSCH are both Downlink Control Information (DCI) scheduled/triggered for transmission on the PUSCH, and the SP-CSI on PUCCH and the P-CSI are Media Access Control (MAC) triggered or Radio Resource Control (RRC) configured for transmission on the PUCCH. In addition to a-CSI, other CSI reporting types are RRC configured with its period (and slot offset within the period), and once configured or activated, the UE will report in a specific slot of each period.

The embodiment of the invention provides a CSI processing method, a processing device and UE (user equipment). the UE can acquire first information and then determine a CSI processing mode in a first reporting period according to the first information. Since the first information may represent a decoding result of downlink transmission in the first time period or represent a measurement result of CSI in the first reporting period, an end position of the first time period is at least no later than a start position of a reporting resource of the CSI in the first reporting period. That is, before reporting the CSI in the first reporting period, the UE may determine, according to a decoding result of downlink transmission in the first time period, a CSI processing manner in the first reporting period, report the CSI in the first reporting period, or abandon reporting the CSI in the first reporting period; in the embodiment of the present invention, the UE may first determine whether the UE needs to report the CSI in one reporting period, abandon reporting the CSI, and abandon measurement according to the first information, and then the UE may process the CSI according to the processing method of the CSI in the reporting period determined by the first information, so that the consumption of the UE measurement and the uplink feedback power may be saved without reporting the CSI or abandoning measuring the CSI. Under the condition that the network equipment configures the same CSI feedback resources for a plurality of UEs, part of the UEs can be free from reporting the CSI, and under the condition that resource conflict is controllable, the expense of the network equipment for receiving the CSI feedback resources can be saved.

The CSI processing method, the processing device and the UE provided by the embodiment of the invention can be applied to a communication system. The method can be particularly applied to the process of reporting the CSI by the UE based on the communication system.

The embodiment of the invention can be applied to various communication systems, such as a 5G communication system, a future evolution system or other communication systems. A variety of application scenarios may be included, such as machine-to-machine (M2M), D2M, enhanced mobile internet (eMBB), and ultra-high reliability and ultra-low latency communications (urrllc). The specific method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Fig. 1 illustrates an architecture diagram of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system may include a UE 01 and a network device 02. Wherein, the UE 01 and the network device 02 can establish connection and communicate.

A UE is a device that provides voice and/or data connectivity to a user, a handheld device with wired/wireless connectivity, or other processing device connected to a wireless modem. A UE may communicate with one or more core network devices via a Radio Access Network (RAN). The UE may be a mobile terminal such as a mobile phone (or "cellular" phone) and a computer having a mobile terminal, or a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges speech and/or data with the RAN, such as a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and so on. A UE may also be referred to as a User Agent (User Agent) or a terminal device, etc. As an example, in the embodiment of the present invention, fig. 1 illustrates that the UE is a mobile phone.

The network device may be a base station. A base station is a device deployed in a RAN for providing wireless communication functions for UEs. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example, in third generation mobile communication (3G) networks, referred to as base stations (NodeB); in a Long Term Evolution (LTE) system, referred to as an evolved NodeB (eNB) or eNodeB; in fifth generation mobile communication (5G) networks, referred to as a gNB, and so on. As communication technology evolves, the name "base station" may change.

A CSI processing method and device provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Based on the communication system shown in fig. 1, an embodiment of the present invention provides a CSI processing method applied to a UE, and as shown in fig. 2, the CSI processing method may include

steps

201 and 202 described below.

Step 201, the UE acquires first information.

The first information represents a decoding result of downlink transmission in a first time period or represents a measurement result of the CSI in a first reporting period, and the end position of the first time period is at least no later than the start position of the reporting resource of the CSI in the first reporting period.

In an example, one downlink transmission decoding success corresponds to one positive Acknowledgement (ACK), one downlink transmission decoding failure corresponds to one Negative Acknowledgement (NACK), and the "decoding result of downlink transmission" may be a ratio of the number of NACKs to the number of ACKs in the first time period, or may be a sum of the number of NACKs and the number of ACKs to the number of NACKs in the first time period, i.e., a ratio of the total number of downlink transmissions.

In an example, a successful decoding of one Transport Block (TB) or Code Block Group (CBG) of one downlink transmission corresponds to one ACK, a failed decoding of one transport block or code block group of one downlink transmission corresponds to one NACK, and a decoding result of the downlink transmission may be a ratio of the number of NACKs to the number of ACKs in the first time period, or a sum of the number of NACKs and the number of ACKs in the first time period, that is, a ratio of the total number of transport blocks or code block groups of the downlink transmission.

In the embodiment of the present invention, the CSI measurement result includes: reference Signal Received Power (RSRP), Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), Rank Indicator (RI), and the like.

Step 202, the UE determines a CSI processing mode in the first reporting period according to the first information.

It should be noted that, the CSI may be reported in a reporting period or discarded in the reporting period, where the discarding of the report in the reporting period may be measuring the CSI in the reporting period, but canceling the reporting of the CSI; abandoning reporting in the reporting period may also be to cancel measuring CSI and cancel CSI reporting in the reporting period.

It can be understood that, after the UE determines the CSI processing mode in the first reporting period, the UE processes the CSI according to the CSI processing mode in the first reporting period determined according to the first information, for example, reporting the CSI, abandoning reporting the CSI, or abandoning measuring the CSI.

It can be understood that, if the UE determines to abandon measuring the CSI, the UE also abandons reporting the CSI in the corresponding reporting period.

According to the CSI processing method provided by the embodiment of the invention, the UE can acquire the first information and then determine the CSI processing mode in the first reporting period according to the first information. Since the first information may represent a decoding result of downlink transmission in the first time period or represent a measurement result of CSI in the first reporting period, an end position of the first time period is at least no later than a start position of a reporting resource of the CSI in the first reporting period. That is, before reporting the CSI in the first reporting period, the UE may determine, according to a decoding result of downlink transmission in the first time period, a CSI processing manner in the first reporting period, report the CSI in the first reporting period, or abandon reporting the CSI in the first reporting period; in the embodiment of the present invention, the UE may first determine whether the UE needs to report the CSI in one reporting period, abandon reporting the CSI, and abandon measurement according to the first information, and then the UE may process the CSI according to the processing method of the CSI in the reporting period determined by the first information, so that the consumption of the UE measurement and the uplink feedback power may be saved without reporting the CSI or abandoning measuring the CSI. Under the condition that the network equipment configures the same CSI feedback resources for a plurality of UEs, part of the UEs can be free from reporting the CSI, and under the condition that resource conflict is controllable, the expense of the network equipment for receiving the CSI feedback resources can be saved.

Optionally, in an embodiment of the present invention, the CSI is semi-static CSI, periodic CSI, or aperiodic CSI.

It should be noted that the semi-static CSI requires the network device to trigger activation, and after the semi-static CSI is configured by the UE, if the semi-static CSI is not activated, the UE does not need to report the CSI; after the UE configures and activates the semi-static CSI, the UE periodically reports the CSI according to the configured periodicity. The aperiodic CSI requires the network device to configure and trigger, and the UE reports the CSI on the scheduled resource after the aperiodic CSI is triggered.

It can be understood that, when the UE reports the semi-static CSI or the periodic CSI periodically, the UE may determine, according to the first information, a CSI processing method provided in the embodiment of the present invention before reporting the semi-static CSI or the periodic CSI in the first reporting period, and may save consumption of UE measurement and uplink feedback power and cost of CSI feedback resources when the CSI is not reported or measurement of the CSI is abandoned.

It can be understood that, when reporting the aperiodic CSI, the UE may also determine, based on the CSI processing method provided in the embodiment of the present invention, a CSI processing manner according to a CSI measurement result or a decoding result of uplink transmission in a first time period before reporting the CSI. After receiving the trigger signaling of the a-CSI, the UE may perform measurement of the a-CSI, and determine whether to report the CSI according to a measurement result of the a-CSI, or determine whether to report the CSI according to a decoding result of downlink transmission in a first time period after receiving the trigger signaling of the a-CSI, where the first time period may be a predefined time period before the DCI corresponding to the a-CSI is triggered. Under the condition of not reporting the CSI or abandoning the measurement of the CSI, the consumption of UE measurement and uplink feedback power can be saved, and the expenditure of CSI feedback resources can also be saved.

Optionally, in this embodiment of the present invention, the first time period is: the second period of time or a period of time after the second period of time is shifted forward by the first shift amount.

Optionally, the first offset is predefined or network device configured.

Specifically, the first offset is a predefined specific value, or is obtained according to a certain rule, for example, determined according to the processing capability of the UE.

For example, the first offset may be determined according to a UE calculation CSI time determination (i.e., CSI calculation time) defined in the protocol. Or may be determined according to the PUSCH preparation time under different UE capabilities (e.g., UE capability 1 and UE capability 2) or PDSCH processing time under different UE capabilities (e.g., UE capability 1 and UE capability 2) defined in the protocol.

Alternatively, the second period of time may be any one of the following (1) to (5):

(1) and the time period corresponding to the second reporting period.

And the second reporting period is a previous reporting period of the first reporting period.

(2) And the time period from the initial position of the reporting time unit in the second reporting period to the initial position of the reporting time unit in the first reporting period.

(3) And the time period from the end position of the reporting time unit in the second reporting period to the end position of the reporting time unit in the first reporting period.

(4) And the time period from the initial position of the reporting resource in the reporting time unit in the second reporting period to the initial position of the reporting resource in the reporting time unit in the first reporting period.

(5) And the time period from the end position of the reporting resource in the reporting time unit in the second reporting period to the end position of the reporting resource in the reporting time unit in the first reporting period.

In the embodiment of the present invention, the reporting time unit is a time unit in which the UE reports the CSI in one reporting period. The reporting resource in the reporting time unit refers to a PUCCH or PUSCH resource for the UE to carry the reported CSI in one reporting period. The PUCCH resource or PUSCH resource carrying CSI in one reporting period may be a PUCCH resource or PUSCH resource initially configured by RRC or activated by DCI scheduling, or may be a PUCCH resource or PUSCH resource multiplexed by CSI reporting and other uplink transmissions, for example, when a PUCCH time domain resource carrying CSI and a PUCCH time domain resource carrying hybrid automatic repeat request acknowledgement (HARQ-ACK) are overlapped, the UE multiplexes CSI and HARQ-ACK on one PUCCH resource for transmission.

In one example, a time unit may be a slot (slot) or a sub-slot (sub-slot). Under the condition that the reporting time unit is a reporting time slot, the starting position of the reporting time unit refers to the starting position of the reporting time slot in a reporting period, and the ending position of the reporting time unit refers to the ending position of the reporting time slot in the reporting period. Under the condition that the reporting time unit is a reporting sub-time slot, the starting position of the reporting time unit refers to the starting position of the reporting sub-time slot in one reporting period, and the ending position of the reporting time unit refers to the ending position of the reporting sub-time slot in one reporting period.

In an example, the starting position of the reporting resource in the reporting time unit refers to a starting Orthogonal Frequency Division Multiplexing (OFDM) symbol position of a PUCCH or PUSCH resource carrying the reported CSI in one reporting period, and the starting position of the reporting resource in the reporting time unit refers to a last OFDM symbol position of the PUCCH or PUSCH resource carrying the reported CSI in one reporting period.

Specifically, the first time period may be a time period in which the second time period is entirely shifted forward by the target time.

In combination with the second time period, the first time period in the embodiment of the present invention may be any one of the following:

(a) the first time period is a time period of forward translation of the target time by a time period corresponding to the second reporting period. That is, the first time period is a time period from the target time before the start position of the second reporting period to the target time before the end position of the second reporting period.

(b) The first time period is a time period of shifting the target time forward from the time period from the starting position of the reporting time unit in the second reporting period to the starting position of the reporting time unit in the first reporting period. That is, the first time period is a time period from the target time before the starting position of the reporting time unit in the second reporting period to the target time before the starting position of the reporting time unit in the first reporting period.

(c) The first time period is a time period of shifting the target time forward from the time period from the end position of the reporting time unit in the second reporting period to the end position of the reporting time unit in the first reporting period. That is, the first time period is a time period from the target time before the end position of the reporting time unit in the second reporting period to the target time before the end position of the reporting time unit in the first reporting period.

(d) The first time period is a time period of shifting the target time forward from a time period from the starting position of the reporting resource in the reporting time unit in the second reporting period to the starting position of the reporting resource in the reporting time unit in the first reporting period. That is, the first time period is a time period from the target time before the starting position of the reporting resource in the reporting time unit in the second reporting period to the target time before the starting position of the reporting resource in the reporting time unit in the first reporting period.

(e) The first time period is a time period of shifting the target time forward from a time period from the end position of the reporting resource in the reporting time unit in the second reporting period to the end position of the reporting resource in the reporting time unit in the first reporting period. That is, the first time period is a time period from the target time before the ending position of the reporting resource in the reporting time unit in the second reporting period to the target time before the starting position of the reporting resource in the reporting time unit in the first reporting period.

Alternatively, the target time may be determined according to the UE capability, or determined according to the CSI computation time, or predefined or configured by the network device.

In the embodiment of the invention, the P-CSI can be carried on PUCCH for transmission, the SP-CSI can be carried on PUCCH for transmission (namely SP-CSI on PUCCH), and can also be carried on PUSCH for transmission (namely SP-CSI on PUSCH). Wherein, the SP-CSI and the P-CSI can be transmitted on the PUCCH by the UE triggered by the network equipment through MAC or configured by RRC. The starting symbol of the PUCCH for transmitting CSI is determined by RRC configuration of the PUCCH for transmitting CSI, and the starting symbol of the PUSCH for transmitting CSI is indicated by the activation DCI.

It should be noted that, in the following description,in units of time slots, period T_CSIAnd a slot offset of T_offsetConfigured by the RRC parameter reportSlotConfig, unless special case, the UE will be n at System Frame Number (SFN)_fAnd time slots in the frame are numbered as

And mu represents the subcarrier spacing (SCS) of the uplink BWP where the CSI report is transmitted. Wherein, for P-CSI and SP-CSI on PUCCH, the frame number n_fAnd intra slot numbering

For SP-CSI on PUSCH, frame number n_fAnd intra slot numbering

Indicates the frame number where the initial SP-CSI on PUSCH transmission obtained according to the activated DCI is located,

and the time slot number in the frame where the initial SP-CSI on PUSCH transmission obtained according to the activated DCI is located is shown.

Fig. 3 is a schematic diagram of a CSI reporting period according to an embodiment of the present invention. Suppose that the reporting period of the CSI is 4 slots, and the slot offset in the period is 1 slot, that is, the 2 nd slot in each period is the reporting slot of the CSI. The UE may report CSI at the 2 nd slot in cycle 1 and at the 2 nd slot in cycle 2 as shown in fig. 3. More specifically, assume that the reporting resource of CSI in each reporting slot occupies 4 OFDM symbols, and the reporting resource is from the 7 th symbol to the 10 th symbol in one slot, and in combination with fig. 3, that is, the OFDM symbols for transmitting CSI are from the 7 th OFDM symbol to the 10 th OFDM symbol. The CSI may be carried on PUCCH for transmission at the 7 th OFDM symbol to the 10 th OFDM symbol, and may also be carried on PUSCH for transmission at the 7 th OFDM symbol to the 10 th OFDM symbol.

For convenience of description, a location of the first time period in the embodiment of the present invention is described with reference to fig. 3, where a first reporting period is period 2, and a second reporting period is period 1.

Example 1: as shown in fig. 4 (a), the first time period may be a time period of the second reporting period, that is, the first time period is a time period T from the starting position to the ending position of the period 1.

Example 2: as shown in (b) of fig. 4, the first period may be a period after the second reporting period is shifted forward by the first offset amount, that is, the first period is a period after moving forward by a time T1 for the whole period T shown in (a) of fig. 4.

Example 3: as shown in fig. 5 (a), the first time period may be from the starting position of the reporting time unit in the second reporting period to the starting position of the reporting time unit in the first reporting period (i.e., reporting time slot 2), that is, the first time period is from the starting position of time slot 2 in period 1 to the starting position of time slot 2 in period 2.

Example 4: as shown in fig. 5 (b), the first time period may be a time period from the starting position in the reporting time unit in the second reporting period to the starting position in the reporting time unit in the first reporting period shifted forward by the first offset amount, that is, the first time period is a time period from the position T1 before the starting position of slot 2 in cycle 1 to the position T1 before the starting position of slot 2 in cycle 2.

Example 5: as shown in fig. 5 (c), the first time period may be from the end position in the reporting time unit in the second reporting period to the end position in the reporting time unit in the first reporting period, that is, the first time period is from the start position of the time slot 2 in the period 1 to the start position of the time slot 2 in the period 2.

Example 6: as shown in (d) of fig. 5, the first time period may be a time period from the end position in the reporting time unit in the second reporting period to the end position in the reporting time unit in the first reporting period, which is shifted forward by the first offset amount, that is, the first time period is a time period from the end position of slot 2 in cycle 1 to the position T1 before the end position of slot 2 in cycle 2 to the position T1 before the end position of slot 2 in cycle 2.

Example 7: as shown in fig. 6 (a), the first time period may be a time period from a starting position of the reporting resource (i.e., symbol 7 to symbol 10) in the reporting time unit (i.e., slot 2 of cycle 1) in the second reporting period to a starting position of the reporting resource (i.e., symbol 7 to symbol 10) in the reporting time unit (i.e., slot 2 of cycle 2) in the first reporting period, i.e., the first time period is a time period from symbol 7 of slot 2 in cycle 1 to symbol 7 of slot 2 in cycle 2.

Example 8: as shown in fig. 6 (b), the first time period may be from the end position of the reporting resource in the reporting time unit in the second reporting period to the end position of the reporting resource in the reporting time unit in the first reporting period, that is, the first time period is a time period from the symbol 10 of the slot 2 in the period 1 to the symbol 10 of the slot 2 in the period 2.

Example 9: as shown in fig. 6 (c), the first time period may be a time period from the starting position of the reporting resource in the reporting time unit in the second reporting period to a position shifted forward by a first offset from the starting position of the reporting resource in the reporting time unit in the first reporting period, that is, the first time period is a time period from symbol 6 of slot 2 in period 1 to symbol 6 of slot 2 in period 2 (assuming that the first offset is equal to one OFDM symbol).

It should be noted that, in the embodiment of the present invention, the first offset may be offset in units of cycles, offset in units of slots, offset in units of OFDM symbols, or offset in units of absolute time (e.g., ms), which is not specifically limited in the embodiment of the present invention.

Optionally, in this embodiment of the present invention, the downlink transmission in the first time period may include at least one of the following: downlink transmission corresponding to the specific service; downlink transmission scrambled by a Radio Network Temporary Identifier (RNTI); downlink transmission scheduled by Downlink Control Information (DCI) of a specific format; downlink transmission scheduled by DCI of a specific control resource set (CORESET); downlink transmission scheduled by DCI of a specific search space (search space).

Specifically, in the case that the downlink transmission is a Physical Downlink Shared Channel (PDSCH), the downlink transmission in the first time period may include at least one of the following: PDSCH of specific traffic, PDSCH scrambled with specific RNTI, PDSCH scheduled by DCI of specific format, PDSCH scheduled by DCI of specific CORESET, PDSCH scheduled by DCI of specific search space.

For example, the PDSCH of a specific service may be MBMS PDSCH, i.e., PDSCH related to transmitting MBMS service.

Optionally, in this embodiment of the present invention, at least one of the start time domain position of the downlink transmission, the end time domain position of the downlink transmission, the start time domain position of the DCI of the downlink transmission, and the end time domain position of the DCI of the downlink transmission is located in the first time period.

It is to be understood that at least one of the transmission start position and the transmission end position of the downlink transmission is located in the first time period, that is, the downlink transmission is transmitted in the first time period in its entirety, and a part of the downlink transmission is transmitted in the first time period. For example, the downlink transmission starts at a time before the first time period, and ends at a time in the first time period or at a time after the first time period; the downlink transmission starts at a time between the first time periods and ends at another time between the first time periods or at a time after the first time periods.

Optionally, the downlink transmission in the first time period may be continuous downlink transmission or discontinuous downlink transmission, which is not specifically limited in this embodiment of the present invention.

In the embodiment of the present invention, based on the first information, the UE determines the CSI processing mode in the first reporting period, which may be implemented by the following first possible implementation manner or second possible implementation manner.

First possible implementation

In the case that the first information is used to indicate the decoding result of the downlink transmission in the first time period, the step 202 in the above embodiment may be specifically executed by the following step 202a1 or step 202a 2:

step 202a1, if the decoding result indicates that the decoding success ratio is within the first range, the UE determines to report the CSI in the first reporting period.

The decoding success ratio is the ratio of the downlink transmission in the first time period occupied by the successfully decoded downlink transmission in the first time period.

Specifically, if the decoding success ratio indicates that there are more downlink transmissions failed in decoding in the first time period, indicating that the downlink transmission decoding fails, the UE may report the CSI, if the UE has measured the CSI, the UE reports the CSI, and if the UE does not measure the CSI, the UE performs CSI measurement and reports.

It is understood that, in the embodiment of the present invention, the decoding success ratio in the first range may be used to indicate that the decoding fails in the first time period.

Optionally, in this embodiment of the present invention, the first range is configured or predefined for the network device.

Step 202a2, if the decoding result indicates that the decoding success ratio is outside the first range, the UE determines to abandon reporting of the CSI in the first reporting period.

Based on the scheme, before reporting the CSI in the first reporting period, the UE may determine, according to a decoding result of downlink transmission in the first time period, a CSI processing manner in the first reporting period, report the CSI in the first reporting period, or abandon reporting the CSI in the first reporting period; compared with the mode that the UE needs to report the CSI in each reporting period in the related technology, the UE can firstly judge whether the UE needs to report the CSI, abandon to report the CSI and abandon to measure in one reporting period according to the decoding result, then the UE can process the CSI according to the processing mode of the CSI in the reporting period determined by the first information, and the consumption of UE measurement and uplink feedback power can be saved under the condition that the CSI is not reported or the CSI is abandoned. Under the condition that the network equipment configures the same CSI feedback resources for a plurality of UEs, part of the UEs can be free from reporting the CSI, and under the condition that resource conflict is controllable, the expense of the network equipment for receiving the CSI feedback resources can be saved.

Second possible implementation

In the case that the first information is used to indicate a measurement result of CSI in the first reporting period, the step 202 may be specifically executed in step 202b1 or step 202b 2:

step 202b1, if the first parameter value in the measurement result of the CSI in the first reporting period is a preset value or within a preset range, the UE determines to report the CSI in the first reporting period.

Wherein the first parameter value is at least one of: reference signal received power, channel quality indication, precoding matrix indication, rank indication.

Optionally, in this embodiment of the present invention, the preset value is configured or predefined by the network device.

Optionally, in this embodiment of the present invention, the preset range is configured or predefined by the network device.

Step 202b2, if the first parameter value in the measurement result of the CSI in the first reporting period is not a preset value or is not within a preset range, the UE determines to abandon reporting the CSI in the first reporting period.

Illustratively, the UE determines whether to feed back the CSI according to whether the measured RSRP is within a preset range. For example, the UE may determine whether to feed back the CSI according to whether the measured RSRP value is between [ threshold 1 and threshold 2], indicate that the distance between the UE and the base station is long or that the channel state corresponding to the UE is poor if the RSRP value is too small, e.g., smaller than threshold 1, and indicate that the distance between the UE and the base station is short or that the channel state corresponding to the UE is good if the RSRP value is large, e.g., larger than threshold 2. The UE does not feed back the CSI, and if the RSRP is between the value of [ threshold 1 and threshold 2], the UE feeds back the CSI.

It should be noted that, in the broadcast/multicast service system, the base station cannot only consider the reception situation of the cell center or the UE with good channel condition, but also needs to consider the UE far away from the cell or the UE with poor channel condition, but if some UEs are too far away or the channel condition is too poor, the base station cannot be used as a determining factor for the scheduling decision of the base station, otherwise the throughput of the whole system is affected. Therefore, the UE determines how to process the CSI according to the processing method, so that the CSI feedback received by the base station is neither feedback by the UE with a good channel state (or in the center of the cell) nor feedback by the UE with a poor channel state (or in the edge of the cell), thereby saving resources and power overhead of the CSI feedback.

In the embodiment of the invention, in the broadcast/multicast service system, if the UE processes the CSI according to the decoding result of the PDSCH or the measurement result of the CSI, when the PDSCH is successfully decoded, the channel condition is better, or the UE is closer to the center of the cell, the UE may not feed back the CSI, so the base station may configure the same CSI feedback resource for a plurality of UEs, but only a few UEs or one UE may feed back the CSI on the resource, so that the base station does not need to configure different feedback resources for each UE, thereby saving more costs of CSI feedback resources.

Based on the scheme, before the UE reports the CSI in the first reporting period, the UE may obtain a measurement result of the CSI in the first reporting period, and determine a CSI processing mode in the first reporting period according to the measurement result. Under the condition that the network equipment configures the same CSI feedback resources for a plurality of UEs, part of the UEs can be free from reporting the CSI, and under the condition that resource conflict is controllable, the expense of the network equipment for receiving the CSI feedback resources can be saved.
