Description

[Technical field]

[0001] This application claims priority to Chinese Patent Application No. 201910117676.1, filed with the China Intellectual Property Office (CNIPA) on February 15, 2019, the disclosure of which is incorporated herein by reference in its entirety.

[0002] (Technical field) This application relates to, but is not limited to, communications technologies, such as methods and apparatus for transmitting information. [Background technology]

[0003] Related new radio access technology protocols support dynamic switching of transmission reception points (TRPs), thereby enabling multiple TRPs to serve one terminal in a time-division manner, thus improving spectrum efficiency or link robustness. However, the NR protocol does not allow multiple TRPs to serve one terminal simultaneously in the same time domain resource. In order to increase the flexibility of base station deployment and reduce link delay, it is necessary to consider a mechanism in which multiple TRPs can serve one terminal simultaneously in the same time domain resource, or a scenario in which multiple TRPs can schedule the same user independently of each other in the absence of ideal backhaul. The manner in which multiple TRPs serve the same user not only increases link robustness but also improves spectrum efficiency. However, how to enable a system in which multiple TRPs serve the same user and operate effectively is the main issue considered in this specification.

[0004] For example, in the related NR protocol, up to eight logical channels and eight logical channel groups (LCGs) are configured for one terminal. One logical channel corresponds to one scheduling request (SR) configuration, i.e., one SR identifier (SRID). One SRID may correspond to multiple physical uplink control channel (PUCCH) resources in multiple bandwidth parts (BWPs) / component carriers (CCs), but only one PUCCH resource in one BWP. One LCG may correspond to only one buffer state at a given moment. That is, one LCG can only accommodate one buffer size at a given moment to feed back the amount of new data corresponding to the LCG and to be transmitted.

[0005] When one user equipment (UE) is served by two TRPs, for example, when one terminal can transmit a physical uplink shared channel (PUSCH) to two TRPs in one time unit or the same time domain resource, especially when there is no ideal backhaul between the two TRPs, the related SR mechanism and buffer status transmission method need to be extended so that the terminal communicates with two TRPs through two uplinks in one BWP.

[0006] On the other hand, the problem of how to reduce signaling overhead and increase parameter flexibility when multiple TRPs schedule one user independently of each other is also considered in this specification.

[0007] In a second aspect, the problem of how to enhance the feedback of channel state information (CSI) when two TRPs serve one terminal, or more precisely, when two TRPs transmit PDSCH to the terminal and transmit the same data information, is also considered in this specification, such that both the link robustness and the spectral efficiency of the system are improved.

[0008] In a third aspect, the problem of how to reduce signal interference between two TRPs operating independently of each other in one cell is also considered in this specification when there is no ideal backhaul between the two TRPs and the two TRPs share one physical cell ID but can schedule users independently of each other.

[0055] The embodiments of the present application are described in detail hereinafter with reference to the drawings. It should be noted that, if not contradictory, the embodiments and features thereof described herein can be combined with each other.

[0056] The steps illustrated in the flowcharts in the figures may be performed, for example, by a computer system capable of executing a set of computer-executable instructions. Furthermore, although a logical sequence is illustrated in the flowcharts, the steps illustrated or described may, in some cases, be performed in a different sequence than those described herein.

[0057] In the following embodiment, the spatial relationship information of the uplink reference signal 1 indicates one reference signal 2. When the reference signal 2 is an uplink reference signal, the spatial transmission filter of the uplink reference signal 1 is obtained according to the spatial transmission filter of the reference signal 2. Alternatively, when the reference signal 2 is a downlink reference signal, the spatial transmission filter of the uplink reference signal 1 is obtained according to the spatial reception filter of the reference signal 2. The spatial filter 1 is obtained according to the spatial filter 2 in the following manner: the two are the same, or the difference between the central angle of the spatial filter 1 and the central angle of the spatial filter 2 is within a certain range.

[0058] In the following embodiments, the downlink control channel includes a physical downlink control channel (PDCCH) and the downlink data channel includes a physical downlink shared channel (PDSCH).

One search space set includes one or more search spaces. Each search space corresponds to one cohesion. One quasi-co-location reference signal set corresponds to one transmission configuration indicator (TCI) state. The demodulation reference signals in one control channel demodulation reference signal port group satisfy the quasi-co-location relationship. The demodulation reference signals in different control channel demodulation reference signal port groups do not satisfy the quasi-co-location relationship. Different quasi-co-location reference signal sets represent different control channel spatial domain resources.

That is, the SR information is used to indicate whether the LCG or buffer corresponding to the SRID has new data to be transmitted. That is, the SR information is used to request PUSCH resources for transmitting new data. For example, a positive SR indicates that the LCG or buffer corresponding to the SRID has new data to be transmitted, and a negative SR indicates that the LCG or buffer corresponding to the SRID does not have new data to be transmitted.

[0063] In the following embodiment, the buffer status report includes the buffer size of the LCG, which is the packet size of the data to be transmitted corresponding to the LCG.

[0170] The N scheduling request resources are triggered simultaneously or separately, where "triggered" means "transmitted". "Transmitted simultaneously" means "transmitted at the same time" but does not mean that the N scheduling request resources occupy the same time domain resource. "Transmitted separately" means that the N scheduling request resources are determined to be triggered / transmitted without following their respective buffer states.

[0171] In the above embodiment, N is 2 or greater.

[0172] In this embodiment of the present application, the method satisfies at least one of the following features: different control channel resources of the N uplink control channel resources belong to different uplink control channel resource groups; a reference signal port in one reference signal port group of the N reference signal port groups corresponds to one spatial relationship information; or N is equal to L.

[0173] In this embodiment of the present application, the scheduling request resource includes at least one of an uplink control channel resource, a reference signal port of one uplink control channel resource, a time domain resource group of one uplink control channel resource, a frequency domain resource group of one uplink control channel resource, or a time-frequency resource group of one uplink control channel resource.

[0175] In this embodiment of the present application, the uplink control channel includes a PUCCH and the uplink data channel includes a PUSCH.

[0176] In this embodiment of the present application, the uplink control channel resource group satisfies at least one of the following characteristics:

[0177] At most C uplink control channel resources in one uplink control channel resource group in one time unit include HARQ-ACK information, where the value of C belongs to {1, 2, 3, 4}.

[0178] Different uplink control channel resources containing HARQ-ACK information in one time unit belong to different uplink control channel resource groups.

[0179] The intersection between the time units in which different uplink control channel resources in one uplink control channel resource group are located is empty.

[0180] The intersection between the time units in which different uplink control channel resources in different uplink control channel resource groups are located is non-empty.

[0181] The intersection between the time domain resources occupied by the uplink control channel resources in one uplink control channel resource group is empty.

[0182] The intersection between the time domain resources occupied by the uplink control channel resources in different uplink control channel resource groups is non-empty.

[0183] One uplink control channel resource group corresponds to at least one fifth type parameter. The at least one fifth type parameter includes at least one of a downlink control channel resource group, a process number set, a TCI state group, or a spatial relationship information group. Different uplink control channel resource groups are scheduled by different downlink control channel resource groups. Alternatively, uplink control information (UCI) in different uplink control channel resource groups corresponds to HARQ-ACK information corresponding to a PDSCH scheduled by different downlink control channel resource groups and / or aperiodic channel state information (APCSI) scheduled by different downlink control channel resource groups.

[0184] Two or more uplink control channel resource groups are located within one BWP.

[0185] In this embodiment of the present application, SR information or buffer status information is transmitted based on the first type of information such that communication with at least one TRP through at least one uplink is achieved.

[0186] (Embodiment 1) In this embodiment, when two transmission reception points (TRPs) serve one terminal 1, especially when there is no ideal backhaul between the two TRPs as shown in Fig. 3, both TRP0 and TRP1 can schedule uplink and downlink resources of terminal 1. TRP0 transmits downlink control information (DCI) 0 on downlink (DL) 0. DCI 0 is used to schedule terminal 1 and transmit physical uplink shared channel (PUSCH) 0 through panel 1 on uplink (UL) 0. TRP1 transmits DCI 1 on DL 1. DCI 1 is used to schedule terminal 1 and transmit PUSCH 1 through panel 2 on UL 1. PUSCH0 and PUSCH1 also belong to the same component carrier (CC) or the same bandwidth portion (BWP); or the time domain resource intersection between PUSCH0 and PUSCH1 is non-empty, but the frequency domain resource intersection between PUSCH0 and PUSCH1 is empty (i.e., frequency partitioned); or the time domain resource intersection between PUSCH0 and PUSCH1 is non-empty, and the frequency domain resource intersection between PUSCH0 and PUSCH1 is also non-empty (i.e., space partitioned).

[0187] In order to reduce the complexity of the terminal, the two TRPs share one medium access control (MAC) entity of the UE. That is, the TRPs correspond to one serving cell group (SCG). Under this assumption, the main problem to be solved in this embodiment is how to enable the terminal to communicate with the two TRPs separately on two ULs. One or more of the following enhancement schemes may be used to reduce the communication between the TRPs and improve resource utilization or link robustness.

[0188] In the following description, as shown in Figure 4, the hybrid automatic repeat request acknowledgement (HARQ-ACK) information of the physical downlink shared channel (PDSCH) scheduled by the physical downlink control channel (PDCCH) in different downlink control channel resources is fed back to their respective TRPs in different PUCCH resources, and the channel state information (CSI) scheduled by the PDCCH in different downlink control channel resources is fed back to their respective TRPs in different PUCCH resources. Periodic CSI / SR information corresponding to different TRPs is also fed back to their respective TRPs in different PUCCH resources. In short, HARQ-ACK / CSI / SR information corresponding to different TRPs cannot be combined and transmitted in one PUCCH resource unless there is an ideal backhaul between the two TRPs. For example, HARQ-ACKi / CSIi / SRi information transmitted to TRPi can be combined and transmitted in one PUCCH resource, and {CSIi, HARQ-ACKi, SRi} and {CSIj, HARQ-ACKj, SRj} cannot be combined and transmitted in one PUCCH resource when i is not equal to j. i, j=0, 1. At most C PUCCH resources in one PUCCH resource group contain HARQ-ACK information in one time unit. C is equal to 1 or 2. When C is equal to 1, different PUCCH resources corresponding to HARQ-ACK information in one time unit belong to different PUCCH resource groups. PUCCH resources in one PUCCH resource group can only be in time division multiplexing mode. PUCCH resources in different PUCCH resource groups can be in frequency division multiplexing mode or space division multiplexing mode. The PUCCH resources in different PUCCH resource groups are scheduled by the downlink control channel resources in different downlink control channel resource groups.If two downlink control channel resources correspond to the same PUCCH resource group, i.e., there is an ideal backhaul between the TRPs and i is not equal to j, {CSIi, HARQ-ACKi, SRi} and {CSIj, HARQ-ACKj, SRj} may be combined and transmitted in one PUCCH resource.

[0189] Extension scheme 1: One scheduling request (SR) configuration corresponds to N PUCCH resources (i.e., N scheduling request resources) in one BWP. As shown in FIG. 5, one SR configuration corresponds to one SR identifier (SRID). For one SRID, two PUCCH resources {PUCCH0, PUCCH1} are configured in one BWP. Different PUCCH resources correspond to different TRPs. PUCCH0 is from PUCCH resource group 0. PUCCH0 corresponds to TRP0. PUCCH1 is from PUCCH resource group 1. PUCCH1 corresponds to TRP1. That is, one SRID corresponding to one logical channel or one logical channel group corresponds to N PUCCH resources in one BWP. N is a positive integer equal to or greater than 1. For example, N may be set to 1 when only one TRP is available, and N may be set to 2 or greater when two TRPs are available.

[0190] In one embodiment, a reference signal port group (wherein the reference signal port group includes a reference signal port in PUCCH format 0 and / or a demodulation reference signal port group in other PUCCH formats) of N PUCCH resources corresponding to one SR configuration is not code divided. Furthermore, the time domain resource intersection and / or the frequency domain resource intersection among the N PUCCH resources is empty.

[0191] Alternatively, one SR configuration corresponds to one PUCCH resource in one BWP. One PUCCH resource corresponds to N reference signal port groups (i.e., N scheduling request resources). Each reference signal port group corresponds to one spatial transmission filter, i.e., one spatial relationship information. Reference signal ports in the same reference signal port group correspond to the same spatial relationship information. For example, reference signal ports in different same reference signal port groups use the same radio frequency beam and different digital beams, and reference signal ports in different reference signal port groups use different spatial transmission filters. In one embodiment, different reference signal port groups are not code-multiplexed, i.e., frequency-multiplexed or time-multiplexed.

[0192] Alternatively, one SR configuration corresponds to one PUCCH resource in one BWP. One PUCCH resource corresponds to one reference channel port group. One reference signal port group corresponds to N pieces of spatial relationship information. That is, one DMRS port corresponds to N spatial filters (i.e., N scheduling request resources).

[0193] Alternatively, one SR configuration corresponds to one PUCCH resource in one BWP. One PUCCH resource corresponds to N frequency domain resource groups and / or time domain resource groups (i.e., N scheduling request resources). One frequency domain resource group and / or time domain resource group corresponds to one spatial relationship information.

[0194] In the above description, one SRID corresponds to N scheduling request resources. The scheduling request resources include at least one of a PUCCH resource, a reference signal port group of one PUCCH resource, a time domain resource group of one PUCCH resource, a frequency domain resource group of one PUCCH resource, or a time frequency resource group of one PUCCH resource. The N scheduling request resources may correspond to different buffers. For example, as shown in FIG. 5, each of two scheduling request resources (e.g., the PUCCH resource shown in FIG. 5) corresponds to one buffer, and data in one logical channel or data in one logical channel group is divided into two parts. The two parts of data are stored in buffer 1 and buffer 0, respectively. The difference set and / or intersection between the data in buffer 1 and the data in buffer 0 is non-empty. The different buffers are transmitted to different TRPs. The two buffers may have the same data status. For example, both of the two buffers store positive SR information, or both store negative SR information. The two buffers may have different data states, for example, only one buffer stores positive SR information, i.e. only one buffer has new data to be transmitted, the data in one LCG is allocated to the two buffers according to the signaling information transmitted by the base station and / or the data in one LCG is allocated to the two buffers as the implementation behavior of the terminal.

[0195] Alternatively, as shown in FIG. 6, two scheduling request resources (e.g., PUCCH resources in FIG. 6) correspond to the same buffer. Both of the N scheduling request resources store positive SR information or both store negative SR information. In short, the SR information corresponding to this buffer is transmitted to multiple TRPs, thereby improving the success rate and robustness of SR transmission. Alternatively, the terminal selects one or more of the N scheduling request resources and transmits the SR information corresponding to this buffer on the selected scheduling request resource. For example, the terminal selects a PUCCH resource with low transmission power and transmits the SR information on the selected PUCCH resource. After the SR information is transmitted, the two TRPs may communicate and determine the TRP from which the terminal transmits the PUSCH resource (i.e., whether data is transmitted using PUSCH0, PUSCH1, or both PUSCH0 and PUSCH1).

[0196] Extension Scheme 2: As shown in Figure 7-8, one logical channel corresponds to L SRIDs, where L is a positive integer equal to or greater than 1. One SRID corresponds to one PUCCH resource in one BWP, enabling one logical channel to be associated with two or more PUCCH resources in one BWP.

[0197] As in the extended scheme 1, the L SRIDs may correspond to the same or different SR information. As shown in FIG. 7, the L SRIDs correspond to L buffers. In FIG. 7, L is 2 as an example. The two buffers may correspond to the same or different SR information. For example, both of the two buffers have data to be transmitted, or both do not have data to be transmitted. The L SRIDs may be triggered simultaneously or separately. For example, only a part of the buffer has data to be transmitted. Alternatively, as shown in FIG. 8, the L SRIDs correspond to the same buffer. In this case, the L scheduling request resources corresponding to the L SRIDs correspond to the same SR information. The SR resources corresponding to the L SRIDs may be triggered simultaneously. The terminal transmits one SR information to different TRPs through multiple links to increase the transmission robustness of the SR. Alternatively, the positive SR information is transmitted on the scheduling request resources corresponding to some of the L SRIDs.

[0198] Extension scheme 3: one LCG corresponds to M buffer states. As shown in FIG. 9, different buffer states correspond to different TRPs and different buffers, and different buffer status reports are included in different MAC-CE commands and transmitted in different PUSCHs. For example, when a terminal has data to be transmitted in one LCG, the data in one LCG is divided into two parts and transmitted to different TRPs. That is, in the buffer status reports included in different PUSCHs, one LCG may correspond to different buffer sizes. For example, the buffer size of LCG1 in the buffer status report in PUSCH0 is 1,200 bits, and the buffer size of LCG1 in the buffer status report in PUSCH1 is 800 bits. Alternatively, both the buffer size of LCG1 in PUSCH0 and the buffer size of LCG1 in PUSCH1 are 1,000, but the different 1,000-bit information of LCG1 transmitted to different TRPs after the buffer status report is transmitted is independent of each other and corresponds to buffer 0 and buffer 1, respectively. Alternatively, the difference set between different 1,000-bit information of LCG1 transmitted to different TRPs is empty. That is, the same data is transmitted to different TRPs on two uplinks to increase link robustness. It can also be applied to separate scheduling by multiple TRPs. In one embodiment, PUSCH0 and PUSCH1 correspond to two types of PUSCHs, correspond to two uplink data channel process number pairs, and are scheduled by control channel resources in different downlink control channel resource groups. Different downlink control channel resource groups correspond to different TRPs.

[0199] Alternatively, as shown in FIG. 10, one LCG corresponds to M buffer statuses, where different buffer statuses correspond to different TRPs and the same buffer, and different buffer status reports are transmitted on PUSCHs in different MAC-CE commands.

[0200] Extension Scheme 4: As shown in Figure 11, the SRIDs under one serving cell group (SCG) are divided into two groups (i.e., X SRID groups). Each SRID group corresponds to one TRP, and different SRID groups correspond to different TRPs.

[0201] The intersection between corresponding SRIDs in different SRID groups may be non-empty or empty.

[0202] Each SRID group corresponds to one TRP, and different SRID groups correspond to different TRPs includes each SRID group corresponds to one set of first type parameters, and different SRID groups correspond to different first type parameters. The first type parameters include at least one of PUCCH resource group, type of PUCCH (e.g., different types of PUSCH are scheduled by downlink control channels in different downlink control channel resource groups), downlink control channel resource group, SR information, TCI status group, or spatial relationship information group. One SRID corresponds to one or more logical channels. For example, a total of eight SRIDs are available. The eight SRIDs are divided into two groups. SRID group 1 includes {SRID0-SRID3}. SRID group 2 includes {SRID4-SRID7}. SR information corresponding to logical channels corresponding to SRIDs in SRID group 1 can be combined and fed back in one PUCCH resource / PUSCH. SR information corresponding to logical channels corresponding to SRIDs in different SRID groups cannot be combined and fed back in one PUCCH resource / PUSCH. Here, "combined" means that one positive SR information is selected from one SRID group and then transmitted. For example, when feedback in PUCCH is implemented on SR information corresponding to logical channels corresponding to SRIDs in the same SRID group, when three SRIDs are in a positive SR state, one of the three SRIDs in the positive SR state is fed back on one PUCCH resource in the PUCCH resource group corresponding to the SRID group; when two SRIDs in a positive SR state belong to different SRID groups, the two SRIDs can be fed back on only two PUCCH resources, and the two PUCCH resources belong to different PUCCH resource groups.

[0203] Extension Scheme 5: The LCG under one SCG is divided into Y LCGs. As shown in FIG. 12, the LCG under one SCG is divided into two groups. Each LCG corresponds to one TRP. The intersection between corresponding LCGs in different LCGs can be non-empty or empty. Each LCG corresponds to one TRP, and different LCGs correspond to different TRPs, which includes each LCG corresponds to one set of second type parameters, and different LCGs correspond to different second type parameters. Furthermore, the Y LCGs correspond to Y SRID groups, and the LCGs are in one-to-one correspondence with the SRIDs.

[0204] The second type of parameters includes at least one of a type of PUSCH (e.g., different types of PUSCH channels are scheduled by the downlink control channel in different downlink control channel resource groups), a downlink control channel resource group, a MAC-CE including buffer status reporting, a buffer size, a TCI status group, or a spatial relationship information group.

[0205] One LCG includes one or more logical channels. For example, a total of eight LCGs are available. The eight LCGs are divided into two groups: LCG1 includes {LCG0-LCG3}; LCG2 includes {LCG4-LCG7}; PUSCH0 (first type PUSCH) includes transmission information of buffer size corresponding to LCG in LCG1; PUSCH1 (second type PUSCH) includes transmission information of buffer size corresponding to LCG in LCG2; Buffer status information in one LCG can be combined and fed back in one PUSCH belonging to a type of PUSCH corresponding to one LCG; Buffer status information in different LCGs cannot be combined and fed back in one PUSCH, but can only be fed back in PUSCHs of different types. PUSCHs of different types correspond to different TRPs and are scheduled by different control channel resources.

[0206] Two TRPs are used as an example in the above description, and it is not excluded that in this embodiment, the transmission is performed based on three or more TRPs.

[0207] On the other hand, at least one of N, L, M, X, or Y is associated with the number of uplink control channel resource groups, and / or at least one of N, L, M, X, or Y is associated with the number of downlink control channel resource groups, and / or at least one of N, L, M, X, or Y is associated with the number of transmission configuration indicator (TCI) states, and / or at least one of N, L, M, X, or Y is associated with the number of spatial relationship information groups, and / or the sum of at least two of N, L, M, X, and Y is greater than two. One TCI state includes indication information of one quasi-co-location reference signal set. Different TCI state groups correspond to downlink signals transmitted by different TRPs. Different spatial relationship information groups correspond to downlink signals transmitted by different TRPs.

[0208] In the above description, there is an association between different PUCCH resource groups and different downlink control channel resource groups. In another implementation of this embodiment, there may be a correspondence between different PUCCH resource groups and different TCI state groups. For example, TCI state group 0 corresponds to TRP0, and TCI state group 1 corresponds to TRP1. According to the TCI state group to which the TCI state of the PDSCH belongs, the PUCCH resource group to which the PUCCH resource in which the HARQ-ACK corresponding to the PDSCH is located is determined. For example, when the TCI state of the PDSCH belongs to TCI state group 0, the PUCCH resource in which the HARQ-ACK corresponding to the PDSCH is located belongs to PUCCH resource group 0. For example, when the TCI state of the PDSCH belongs to TCI state group 1, the PUCCH resource in which the HARQ-ACK corresponding to the PDSCH is located belongs to PUCCH resource group 1.

[0209] Similarly, there may be an association between different PUCCH resource groups and different spatial relationship information groups.

[0210] Similarly, there may be an association between different types of PUSCH and different TCI state groups and / or there may be a correspondence between different types of PUSCH and different spatial relationship information groups.

[0211] Two or more LCGs may all be dedicated traffic channels.

[0212] (Embodiment 2) In this embodiment, the PUCCH resource where at least one of the HARQ-ACK of the SR or SPS PDSCH is located is determined. For example, according to a predetermined rule, it is determined that the HARQ-ACK of the SR and / or the SPS PDSCH is in the PUCCH resource in the PUCCH resource group corresponding to the lowest index (or the highest index); and / or according to a predetermined rule, it is determined that the HARQ-ACK of the SR and / or the SPS PDSCH is in the HARQ-ACK codebook in the HARQ-ACK codebook group corresponding to the lowest index (or the highest index); and / or according to the PUCCH resource group where the PUCCH resource for the SR configuration is located, the PUCCH resource where the SR is located is determined.

[0213] The PUCCH resource and / or the HARQ-ACK codebook on which the HARQ-ACK of the SPS PDSCH is located is determined according to at least one of the following pieces of information:

[0214] Scheme 1: A downlink control channel resource group including a control channel for scheduling a semi-persistently scheduled downlink data channel, for example, one HARQ-ACK codebook corresponding to a downlink control channel resource group including a DCI for scheduling an SPS PDSCH, and / or one uplink control channel resource in an uplink control channel resource group including a DCI for scheduling an SPS PDSCH, is a PUCCH resource and / or a HARQ-ACK codebook where the HARQ-ACK of the SPS PDSCH is located.

[0215] Scheme 2: An uplink control channel resource group including an uplink control channel indicated by a control channel for scheduling a semi-persistently scheduled downlink data channel, i.e., an uplink control channel resource indicated in a DCI.

[0216] Scheme 3: An uplink control channel resource group including an uplink control channel corresponding to a semi-persistently scheduled downlink data channel configured by a higher layer.

[0217] Scheme 4: HARQ-ACK codebook corresponding to a given index.

[0218] Scheme 5: A HARQ-ACK codebook corresponding to a fourth type of parameter corresponding to an SPS PDSCH. The fourth type of parameter includes at least one of an uplink control channel resource group, an uplink data channel type, a downlink control channel resource group, a TCI state group, a spatial relationship information group, a process number set, or an antenna group.

[0219] Scheme 1 and / or Scheme 2 may be used when a PDCCH corresponding to an SPS PDSCH exists (i.e., the first SPS PDSCH transmission after DCI activates the SPS PDSCH), and one of Scheme 3, Scheme 4, or Scheme 5 may be used when a PDCCH corresponding to an SPS PDSCH does not exist. Alternatively, Scheme 3 is used when a PDCCH corresponding to an SPS PDSCH does not exist and when only an SPS PDSCH and no other PDSCHs are currently available, otherwise one of Scheme 3, Scheme 4, or Scheme 5 is used when a PDCCH corresponding to an SPS PDSCH does not exist.

[0220] Furthermore, the HARQ-ACK / CSI information to be multiplexed with the HARQ-ACK of the SR and / or SPS PDSCH and fed back in the same PUCCH resource or the same type of PUSCH resource is determined according to the PUCCH resource group to which the PUCCH resource where the HARQ-ACK of the SR and / or SPS PDSCH is located belongs. At least two of the HARQ-ACK / CSI / SR / HARQ-ACK of the SPS PDSCH corresponding to the same PUCCH resource group can be combined and fed back in one PUCCH resource / one PUSCH. At least two of the HARQ-ACK / CSI / SR / HARQ-ACK of the SPS PDSCH corresponding to different uplink control channel resource groups need to be fed back in different PUCCH resources / different PUSCHs.

[0221] Referring to Figure 13, another embodiment of the present application provides an information transmission device. The device includes a first determining module 1301 and an information transmitting module 1302. The first determining module 1301 is configured to determine a first type of information. The information transmitting module 1302 is configured to transmit at least one of scheduling request (SR) information or buffer status information according to the first type of information. The first type of information includes N scheduling request resources of at least one of one logical channel or one LCG in one BWP, L SR configurations corresponding to at least one of one logical channel or one LCG, M buffer statuses corresponding to at least one of one logical channel or one LCG, X SR configuration groups corresponding to one serving cell group, or at least one of Y LCGs corresponding to one serving cell group. Each of N, L, X, Y, and M is a positive integer greater than or equal to 1.

[0222] In this embodiment of the application, SR configurations are in one-to-one correspondence with SR identifiers (SRIDs).

[0223] In this embodiment of the present application, the first determination module 1301 is configured to determine the first type of information in at least one of the following manners:

[0224] Configuration information is received, and a first type of information is determined according to the configuration information, where the configuration information may include the first type of information or may include other information to indicate the first type of information.

[0225] The first type of information is determined according to predefined rules, for example in a pre-agreed manner.

[0226] In this embodiment of the present application, the N scheduling request resources satisfy at least one of the following characteristics:

[0227] The N scheduling request resources correspond to one SR configuration, or the N scheduling request resources correspond to L SR configurations.

[0228] The N scheduling request resources include N reference signal port groups of one uplink control channel resource.

[0229] The N scheduling request resources include N time domain resource groups of one uplink control channel resource.

[0230] The N scheduling request resources include N frequency domain resource groups of one uplink control channel resource.

[0231] The N scheduling request resources include N time-frequency resource groups of one uplink control channel resource.

[0232] The N scheduling request resources correspond to the N spatial relationship information of one reference signal port group of one uplink control channel resource.

[0233] The N scheduling request resources include N uplink control channel resources.

[0234] The N scheduling request resources correspond to the N pieces of spatial relationship information.

[0235] The intersection between the time domain resources and / or the intersection between the frequency domain resources occupied by the N scheduling request resources is empty.

[0236] The N scheduling request resources are included in one time unit. When the N scheduling request resources are periodic resources, the N scheduling request resources are included in one time unit, which means that the N scheduling request resources are included in one time unit in one period.

[0237] The N scheduling request resources correspond to the N periodicity information. The N scheduling request resources include the same or different scheduling request information. The scheduling request information includes a positive SR and a negative SR.

[0238] The N scheduling request resources correspond to one or more buffers, i.e. data in one logical channel or one LCG is allocated to one or more buffers and then transmitted to different TRPs. The buffers are used to buffer new data to be transmitted.

[0239] The N scheduling request resources are triggered simultaneously or separately, where "triggered" means "transmitted". "Transmitted simultaneously" means "transmitted at the same time" but does not mean that the N scheduling request resources occupy the same time domain resource. "Transmitted separately" means that the N scheduling request resources are determined to be triggered / transmitted without following their respective buffer states.

[0240] In the above embodiment, N is 2 or greater.

[0241] In this embodiment of the present application, at least one of the following features is met: different control channel resources of the N uplink control channel resources belong to different uplink control channel resource groups; a reference signal port in one reference signal port group of the N reference signal port groups corresponds to one spatial relationship information; or N is equal to L.

[0242] In this embodiment of the present application, the scheduling request resource includes at least one of an uplink control channel resource, a reference signal port of one uplink control channel resource, a time domain resource group of one uplink control channel resource, a frequency domain resource group of one uplink control channel resource, or a time-frequency resource group of one uplink control channel resource.

[0243] In this embodiment of the application, the method satisfies at least one of the following features: N is greater than or equal to L; N is greater than or equal to M; L is greater than or equal to M; X is equal to Y; at least one of N, L, M, X, or Y is associated with the number of uplink control channel resource groups; at least one of N, L, M, X, or Y is associated with the number of downlink control channel resource groups; at least one of N, L, M, X, or Y is associated with the number of TCI state groups; at least one of N, L, M, X, or Y is associated with the number of spatial relationship information groups; or the sum of at least two of N, L, M, X, and Y is greater than or equal to 3.

[0244] In this embodiment of the present application, the uplink control channel includes a PUCCH and the uplink data channel includes a PUSCH.

For example, the feedback bits included in the HARQ-ACK feedback codebook are arranged in the following order: HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k0)th slot with index 0, HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k1)th slot with index 0, . . . , HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k2)th slot with index 0, . . . , HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k3)th slot with index 0, . . . , HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k4)th slot with index 0, . . . , HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k5)th slot with index 0, . . . , HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k6)th slot with index 0, . . . , HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k7)th slot with index 0, . . . , HARQ-ACK feedback bits corresponding to T time division PDSCHs associated with the second type of information in the (n-k8)th slot with index 0, . . . , HARQ-ACK feedback bits corresponding to T time D HARQ-ACK feedback bits corresponding to the T time division PDSCHs associated with the second type information in the (n-k0)th slot, with index 1, HARQ-ACK feedback bits corresponding to the T time division PDSCHs associated with the second type information in the (n-k1)th slot, with index 1, ..., associated with index 1, (nk DHARQ-ACK feedback bits corresponding to the T time division PDSCHs associated with the second type of information in the (n-k0)th slot. Alternatively, in one HARQ-ACK feedback codebook, the loop of the second type of information is before the time domain PDSCH loop. For example, the HARQ-ACK bits included in the HARQ-ACK feedback codebook and corresponding to the PDSCH in the first time domain resource group in the (n-k0)th slot are arranged in the following order: HARQ-ACK feedback bits corresponding to the PDSCH associated with the second type of information with index 0 of the first time domain resource group in the (n-k0)th slot, HARQ-ACK feedback bits corresponding to the PDSCH associated with the second type of information with index 1 of the first time domain resource group in the (n-k0)th slot, then a loop of the time domain resource group in the (n-k0)th slot, then a loop of slots. D ) denotes the slot index of the PDSCH corresponding to the HARQ-ACK that needs to be fed back in slot n. k0, k1, . . . and k D may be a positive integer or may be a fraction, for example when the subcarrier spacing of the PDSCH is different from the subcarrier spacing of the PUCCH.

[0346] Alternatively, one HARQ-ACK codebook is obtained for each different second type information. That is, the number of HARQ-ACK feedback codebooks is determined according to the number of second type information configured for the terminal. When one second type information is configured for the terminal, it indicates that only one TRP exists or ideal backhaul exists between the TRPs. In this case, only one HARQ-ACK feedback codebook needs to be fed back in one time unit. When two or more second type information are configured for the terminal, multiple TRPs are needed, and there may be no ideal backhaul between the TRPs, or the TRPs can schedule users independently of each other. Therefore, one HARQ-ACK feedback codebook needs to be transmitted to each different TRP. The HARQ-ACK feedback codebook is HARQ-ACK information corresponding to the PDSCH from each different TRP (i.e., associated with the second type information).

[0347] Further, it is operable to determine whether HARQ-ACK codebooks corresponding to the second type of information with different indexes can be combined and fed back in one PUCCH resource / PUSCH according to the signaling information. During the combination, it is operable to link the HARQ-ACK codebooks according to the indexes of the second type of information. For example, the HARQ-ACK codebook corresponding to the second type of information with index 0 is followed by the HARQ-ACK codebook corresponding to the second type of information with index 1. The two combined HARQ-ACK codebooks are input to a channel encoder and encoded. The encoded HARQ-ACK codebook is fed back in one PUCCH resource.

[0348] Furthermore, as shown in FIG. 16, in one TRP, one HARQ-ACK codebook is obtained separately for ultra-reliable low latency communication (URLLC) traffic and high speed large capacity communication (eMBB) traffic. One HARQ-ACK codebook is obtained separately for each different second type information and each different traffic type. As shown in FIG. 17, the second type information with index 0 corresponds to TRP0, and the second type information with index 1 corresponds to TRP1. In each TRP, two HARQ-ACK codebooks are obtained for different traffic types. When there are two second type information and different traffic types, four HARQ-ACK codebooks may exist in one slot. HARQ-ACK codebook 1 and HARQ-ACK codebook 2 are fed back to TRP0. HARQ-ACK codebook 3 and HARQ-ACK codebook 4 are fed back to TRP0. In short, the number of HARQ-ACKs in one slot is determined based on the number of second type information, and one slot is the slot where the resource (PUCCH / PUSCH) for feedback of HARQ-ACK is located.

[0349] Alternatively, when there is an ideal backhaul between two TRPs, four HARQ-ACK feedback codebooks can be combined and then fed back in one PUCCH resource. In this case, the combination order of the four HARQ-ACK codebooks needs to be determined. For example, the combination order is HARQ-ACK codebook 1, HARQ-ACK codebook 3, HARQ-ACK codebook 2, and then HARQ-ACK codebook 4. That is, the HARQ-ACK feedback codebook for URLLC traffic is placed before other HARQ-ACK feedback codebooks. This is because the reliability of bits in the forward direction is higher than the channel reliability of bits in the backward direction during channel coding.

[0350] On the other hand, as shown in Fig. 17, it is required to determine the maximum number of PDSCH / CWs whose intersection of the occupied time domain resources in one BWP / CC is non-empty according to the second type information. When one second type information is configured, the maximum number of PDSCH / CWs whose intersection of the occupied time domain resources in one BWP / CC is non-empty belongs to {1, 2}. When two second type information are configured, the maximum number of PDSCH / CWs whose intersection of the occupied time domain resources in one BWP / CC is non-empty belongs to {1, 2, 3, 4}. Similarly, the number of uplink PUSCH / CWs that can be transmitted simultaneously in the same time domain symbol can also be obtained according to the second type information. The number of uplink PUSCH / CWs whose occupied time domain resources have intersection can also be obtained according to the second type information.

[0351] In the implementation of this embodiment, the number of beam switching is determined according to the TCI state group and / or antenna group in the following manner: when the beams of two signals in different time domain symbols are different, for example, when the signals do not satisfy the quasi-collocation relationship for the spatial reception parameters, it is required to determine whether beam switching occurs between the two signals according to the TCI state group and / or antenna group. For example, when the two signals correspond to different TCI state groups and / or antenna groups, beam switching does not occur between the two signals, i.e., the number of beam switching does not increase; otherwise, beam switching occurs between the two signals, i.e., the number of beam switching increases by one. Although the received beams of the two signals are different, the two received beams corresponding to the two signals correspond to two receiving antennas, and the two receiving antennas are always in the on state on the terminal. Thus, although the received beams of the two signals are different, this cannot be regarded as one beam switching because the receiving antennas are different. In short, the two signals that experience beam switching need to correspond to the same receiving antenna group. The above scheme may be used in a scenario where the number of beam switches of a terminal within one defined time unit cannot exceed a predetermined threshold. Similarly, the number of beam switches may be determined according to other second type information.

[0352] In the above description, the third type of information is determined according to the second type of information. It is also possible to determine the second type of information according to the third type of information.

[0353] In another implementation of this embodiment, one signaling information is transmitted. The one signaling information includes the second type information and the third type information. For example, the signaling information is a MAC-CE command. For example, the MAC-CE control signaling is a MAC-CE control signaling for notifying the third type information, and the MAC-CE control signaling includes index information of the second type information.

[0354] For example, as shown in Figure 18, a MAC-CE command for notifying a mapping between a TCI indication field value in a DCI and an indicated TCI content includes an index of a second type of information, such as a control channel resource group index, and indicates that the content notified by the MAC-CE command is a mapping between a TCI indication field value in a DCI and a TCI content indicated by a TCI indication field value in a DCI corresponding to the index of the second type of information. Ti (i=0, 1, ..., 87) in Figure 18 corresponds to one TCI state in a TCI state list notified by RRC signaling. Ti=1 indicates that the TCI state is activated. Ti=0 indicates that the TCI state is deactivated. The eight values ​​of the TCI indication field (3 bits) in the DCI are in one-to-one correspondence with the TCI states having a Ti value of 1. 18, the index of the control channel resource group is 0 and Ti with a value of 1 includes {T1, T9, T18, T20, T30, T32, T34, T87}. In this case, the table of mapping between TCI bit field values ​​in the DCI of control channel resource group 0 and the indicated TCI content is as shown by Table 1. If the index of the control channel resource group is 1 and Ti with a value of 1 includes {T2, T11, T21, T24, T35, T37, T44, T80}, the table of mapping between TCI bit field values ​​in the DCI of control channel resource group 1 and the indicated TCI content is as shown by Table 2.

[0355] [Table 1]

[0356] [Table 2]

[0357] The MAC-CE command in FIG. 18 carries a downlink control channel resource group index. Of course, the MAC-CE command in FIG. 18 may carry other second type information as mentioned above, for example, a TCI state group index indicating a TCI state group including a TCI state corresponding to Ti. Different TCI state groups may include different numbers of TCI states, so that the number of Ti required may differ. For example, TCI state group 0 corresponds to 88 Ti bits in FIG. 18. For example, TCI state group 1 corresponds to 48 Ti bits in FIG. 18.

[0358] Similarly, Ti in FIG. 18 may be in one-to-one correspondence with the aperiodic CSI trigger states, such that for different DCIs corresponding to different second types of information, the tables of mapping between CSI request fields and CSI indication contents are different.

[0359] Similarly, the configuration information of the aperiodic SRS request field may carry a downlink control channel resource group index for determining a mapping between the bit indication values ​​of the aperiodic SRS request field of the DCI in the downlink control channel resource group and the indicated aperiodic SRS content. Different DCI in different downlink control channel resource groups may correspond to different mappings between the bit indication values ​​of the aperiodic SRS request field and the indicated aperiodic SRS content.

[0360] Similarly, the configuration information of the SRS resource indication field of the DCI may carry a downlink control channel resource group index for determining a mapping between the bit indication value of the SRS resource indication field of the DCI and the indicated SRS resource in the downlink control channel resource group. Different DCI in different downlink control channel resource groups may correspond to different mapping between the bit indication value of the SRS resource indication field and the indicated SRS resource. The SRS resource indication field is used to indicate the spatial filter and / or precoding information and / or antenna port of the PUSCH. For example, the SRS resource indication field is used to indicate one or more RS resources in the SRS set used for codebook / non-codebook. The PUSCH spatial filter and / or precoding information and / or antenna port are obtained according to the indicated SRS resource.

[0361] Similarly, a MAC-CE command for activating or deactivating a semi-periodic CSI-RS / CSI-IM may also carry an index of the second type of information indicating which second type of information corresponds to the semi-periodic CSI-RS / CSI-IM.

[0362] Similarly, the MAC-CE command for activating the PUCCH-resource spatial relationship carries a spatial relationship group index to indicate the spatial relationship group that contains the spatial relationship corresponding to si, where i=0, 1, ..., 7, as shown in Figure 19. Different spatial relationship groups may contain different numbers of spatial relationship information.

[0363] (Embodiment 4) In this embodiment, a correspondence is established between the downlink control channel resource group and the uplink data channel process number set. For example, two downlink control channel resource groups are available, and different downlink control channel resource groups correspond to different TRPs. Different downlink control channel resource groups correspond to different PUSCH process number sets. For example, downlink control channel resource group 0 corresponds to PUSCH process number set {0-15}, and downlink control channel resource group 1 corresponds to PUSCH process number set {16-31}. When the downlink control information (DCI) for scheduling PUSCH in downlink control channel resource group 0 indicates a process number of 0, downlink control channel resource group 0 corresponds to absolute process number 0. When the DCI for scheduling PUSCH in downlink control channel resource group 1 indicates a process number of 0, downlink control channel resource group 1 corresponds to absolute process number 16.

[0364] Alternatively, different downlink control channel resources in two downlink control channel resource groups correspond to different PDSCH process number sets but the same PUSCH process number set. For example, downlink control channel resource group 0 corresponds to PUSCH process number set {0-15} and PDSCH process number set {0-15}, and downlink control channel resource group 1 corresponds to PUSCH process number set {0-15} and PDSCH process number set {16-31}. When the DCI for scheduling PUSCH in downlink control channel resource group 0 indicates a process number of 0, downlink control channel resource group 0 corresponds to absolute process number 0. When the DCI for scheduling PDSCH in downlink control channel resource group 0 indicates a process number of 0, downlink control channel resource group 0 corresponds to absolute process number 0. When the DCI for scheduling PUSCH in downlink control channel resource group 1 indicates a process number of 0, downlink control channel resource group 1 corresponds to absolute process number 0. When the DCI for scheduling the PDSCH in downlink control channel resource group 1 indicates a process number of 0, downlink control channel resource group 1 corresponds to an absolute process number of 16.

[0365] In short, it is required to establish an association between a downlink control channel resource group and at least one of a PUSCH process number set or a PDSCH process number set.

[0366] Alternatively, there is an association between a TCI group / spatial relationship information group and at least one of a PUSCH process number set or a PDSCH process number set.

[0367] Another embodiment of the present application provides an information determining device. The device includes a second determining module configured to perform at least one of obtaining the other of the second type information or the third type information according to one of the second type information or the third type information, or transmitting one first signaling information including the second type information and the third type information. The second type information includes at least one of the following: a downlink control channel resource group, an uplink control channel resource group, a process number set, a transmission configuration indicator (TCI) state group, a spatial relationship information group, or an antenna group. The third type of information includes at least one of the following: a maximum number of data channels or codewords (CWs) transmitted in one time domain symbol of one bandwidth portion (BWP) or component carrier (CC); a maximum number of data channels or CWs with intersecting time domain resources in one BWP or CC; a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) feedback codebook; whether at least two of HARQ-ACK, a Scheduling Request (SR), and Channel State Information (CSI) are fed back in one uplink channel; a number of Semi-Persistent Scheduling Physical Downlink Shared Channel (SPS) signals received in one time domain symbol of one BWP or CC. the maximum number of grant-free physical uplink shared channels (PDSCHs) or CWs transmitted in one time domain symbol of one BWP or CC; a table for mapping between predetermined bit field values ​​in downlink control information (DCI) and the content indicated by the predetermined bit field values; spatial relationship information; quasi-co-location reference signal information; the number of beam switching times; or semi-persistent signal activation or deactivation information.

[0368] In this embodiment of the present application, the second determination module 1801 is configured to determine the third type of information according to the number of the second type of information. For example, the number of the second type of information is used as the third type of information, or the number of the second type of information is calculated according to a predetermined functional relationship, so that the third type of information is obtained. When the second type of information includes a plurality of pieces of information, the number of the second type of information may be the maximum number of the second type of information, may be the minimum number of the second type of information, and / or may be the number of the second type of information calculated according to another functional relationship. The specific functional relationship is not used to limit the protection scope of the embodiment of the present application.

[0369] In this embodiment of the present application, the second determining module 1801 is configured to determine a HARQ-ACK feedback codebook according to the second type of information in at least one of the following manners:

[0370] The number of HARQ-ACK feedback codebooks included in one time unit, whose feedback resource may be one or more slots, is determined according to the second type of information.

[0371] The number of HARQ-ACK feedback bits included in one HARQ-ACK feedback codebook and corresponding to the type of downlink data channel whose classification criterion is the end of the downlink data channel is determined according to the second type information.

[0372] A second type of information loop is introduced in the process of obtaining one HARQ-ACK feedback codebook.

[0373] In this embodiment of the present application, the second determination module 1801 is configured to determine whether at least two of the HARQ-ACK, SR, and CSI are fed back in one uplink channel according to the second type of information in at least one of the following manners: it is determined that at least two of the HARQ-ACK, SR, and CSI corresponding to the same second type of information are fed back in one uplink channel; it is determined that at least two of the HARQ-ACK, SR, and CSI corresponding to different second type information cannot be fed back in one uplink channel; it is determined that at least two of the HARQ-ACK, SR, and CSI corresponding to different second type information are fed back in different uplink channels; or it is determined that, according to the third signaling information, at least two of the HARQ-ACK, SR, and CSI corresponding to different second type information are fed back in one uplink channel. The uplink channel includes an uplink data channel or an uplink control channel corresponding to one uplink control channel resource.

[0374] The device meets at least one of the following characteristics:

[0375] Each piece of second type of information corresponds to one piece of third type of information.

[0376] The one first signaling information includes a medium access control-control element (MAC-CE) command.

[0377] A piece of first signaling information is used to notify one of the second type of information or the third type of information, and includes index information of the one type of information corresponding to the other type of information being notified.

[0378] The predetermined bit field in the DCI includes at least one of a TCI field, a CSI request field, a sounding reference signal (SRS) request field, an uplink control channel resource indication field, or an SRS resource indication field. The SRS request field is used to indicate a non-periodic SRS transmission. In response to a receive beam switch between two signals in different time resources, the two signals correspond to the same second type of information.

[0379] In this embodiment of the present application, in a multi-TRP transmission scenario, an association is established between the second type of information and the third type of information. In this embodiment of the present application, one type of information of the second type of information and the third type of information is used in obtaining the other type of information, such that different second type of information corresponds to different third type of information. Furthermore, different second type of information corresponds to different TRPs, i.e., different TRPs correspond to different third type of information. One signaling information includes the second type of information and the third type of information. In this way, the signaling overhead is reduced, and thus the parameter flexibility and system performance are improved.

[0380] Another embodiment of the present application provides an information determination apparatus, the apparatus including a processor and a computer-readable storage medium, the computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform any of the above-mentioned information determination methods.

[0381] Another embodiment of the present application provides a computer readable storage medium storing a computer program which, when executed by a processor, causes the processor to perform the steps of any of the above-mentioned information determining methods.

[0382] 20, another embodiment of the present application provides a feedback information sending method. The method includes the following steps:

[0383] At step 1900, channel quality indicator (CQI) information is obtained according to at least one of a repetition transmission rate R or a repetition transmission mode.

[0384] In this embodiment of the present application, the repeat transmission mode includes one of the following modes:

[0385] The R layer groups correspond to the R spatial domain resources.

[0386] The R tier groups correspond to R frequency domain resource groups, and the intersections between different frequency domain resource groups are empty.

[0387] The R tier groups correspond to R time domain resource groups, and the intersections between different time domain resource groups are empty.

[0388] The R repeated transmissions correspond to a redundancy version (RV) sequence.

[0389] The data channels corresponding to the R tier groups include repeated transmissions of the same information, where R is a positive integer greater than or equal to 2.

[0390] The R tier groups or one CQI information corresponds to at least one of A channel state information reference signal (CSI-RS) resources, A ranking indicator (RI) information, A precoder matrix indicator (PMI) information, A quasi-co-located reference signal sets (the A quasi-co-located reference signal sets may also be referred to as TCI states, and one TCI state includes one quasi-co-located reference signal set), or A column groups of one PMI (one column of one PMI matrix corresponds to one tier).

[0391] A is equal to 1 or A is equal to R.

[0392] In this embodiment of the present application, the repetition rate R satisfies at least one of the following characteristics:

[0393] When R is 2 or more, one piece of transmission information is repeatedly transmitted on R resources.

[0394] When R is equal to 1, one transmission is not transmitted repeatedly.

[0395] The R resources correspond to at least one of R time domain resources, R spatial domain resources, R frequency domain resources, R reference signal (RS) resources, R quasi-co-located reference signal (RS) sets, R RVs, R scrambling sequences, or R tier groups.

[0396] In this embodiment of the present application, the CQI information is determined in the following manner.

[0397] A SINR-BLER mapping corresponding to each repetition transmission rate and / or repetition transmission mode corresponding to each CQI information is established.

[0398] The SINR is obtained based on the measurement reference signal.

[0399] A SINR-to-BLER mapping corresponding to each modulation and coding scheme (MCS) corresponding to the current repetition rate and / or repetition transmission mode is established.

[0400] A block error rate (BLER) corresponding to the obtained SINR based on the measurement reference signal is obtained according to the obtained SINR-BLER mapping.

[0401] The minimum value of the CQI information, whose BLER is below a pre-set threshold, is obtained.

[0402] In step 1901, CQI information is transmitted.

[0403] In this embodiment of the present application, the CQI information is obtained according to at least one of a repetition transmission rate or a repetition transmission mode. This transmission scheme is closer to the actual PDSCH transmission scheme, thereby enabling the CQI to be fed back more accurately, improving the spectrum efficiency and reducing the interference. Furthermore, the implementation complexity of the base station is reduced, because the base station does not need to calculate the CQI actually used in the PDSCH transmission based on the CQI fed back by the terminal. In this calculation process, the different implementation algorithms between the base station and the terminal will lead to inaccurate calculation.

[0404] (Embodiment 5) In this embodiment, two TRPs transmit the same PDSCH data to one terminal simultaneously. For example, one DMRS port corresponds to two TCI states, or the same transmission information is transmitted in two DMRS ports, and the two DMRSs may correspond to the same or different modulation orders and / or channel code rates. That is, the data is repeatedly transmitted in a space division manner.

[0405] In order for the terminal to feedback an accurate channel quality indicator (CQI), it is required to assume whether the intersection between data from two TRPs is empty when the terminal feeds back the CQI. Based on this assumption, the terminal feeds back the CQI information. As shown in FIG. 21, the base station allocates two CSI-RS resources (CRI1 and CRI2) to the terminal. Each CSI-RS resource includes 32 CSI-RS ports. That is, one CSI-RS resource corresponds to one TRP. The terminal feeds back one (PMI1, RI1) for each CSI-RS resource. As shown in FIG. 21, (PMI1, RI1) is fed back based on CRI1, and (PMI2, RI2) is fed back based on CRI2; then one CQI, for example, CQI0, is fed back based on the two combinations (PMI, RI). Furthermore, the terminal needs to assume a transmission scheme of PDSCH corresponding to two layers corresponding to two combinations (PMI, RI). For example, (PMI1, RI1) is fed back for CRI1, and (PMI2, RI2) is fed back for CRI2. For example, both RI1 and RI2 are 1 (or RI1=2, and RI2=1, but of course other combinations are not excluded). The CQI fed back when different data is transmitted on layers RI1 and RI2 may be different from the CQI fed back when the same data is transmitted on layers RI1 and RI2.

[0406] For example, when the transmission information (i.e., information bits before channel coding) transmitted in layer RI1 and the transmission information (i.e., information bits before channel coding) transmitted in layer RI2 are the same (or when the intersection between the transmission information included in layer RI1 and the transmission information included in layer RI2 is non-empty), CQI1 is fed back to indicate that one TB uses the modulation order, target code rate, and transport block size indicated by CQI1. Furthermore, when each of layer RI1 and layer RI2 includes a channel-coded bit sequence corresponding to one RV of one TB, and the channel-coded bit sequence is transmitted on the CSI reference resource, the probability of occurrence of an error in one TB does not exceed 0.1 (or 0.00001), i.e., each of layer RI1 and layer RI2 includes one RV of one TB, as shown in FIG. 23. Alternatively, layer RI1 and layer RI2 include repeated transmission of the same RV. As shown in FIG. 22, for example, 1,000 channel coded bits corresponding to one RV of one TB are transmitted in each of layers RI1 and RI2.

[0407] When the transmission information transmitted in layer RI1 and the transmission information transmitted in layer RI2 are different, CQI2 is fed back to indicate that one TB uses the modulation order, target code rate and transport block size indicated by CQI2. Furthermore, when layer RI1 and layer RI2 correspond to different channel-coded bits of one RV of one TB, and the channel-coded bits are transmitted on the CSI reference resource (i.e., the intersection between the transmission information included in layer RI1 and the transmission information included in layer RI2 is empty), the probability of occurrence of an error in one TB does not exceed 0.1 (or 0.00001), i.e., one RV of one TB experiences layer mapping across layer RI1 and layer RI2, followed by frequency domain resource mapping, followed by time domain resource mapping. As shown in Figure 24, for example, RV=0 of one TB includes 1,000 channel-coded bits, and the 1,000 bits are modulated into 500 modulation symbols. The 250 modulation symbols corresponding to the odd indices of the 500 modulation symbols are transmitted in layer RI1. The 250 modulation symbols corresponding to the even indices of the 500 modulation symbols are transmitted in layer RI2.

[0408] Furthermore, it is required to assume whether the same data is transmitted in layers RI1 and RI2 in a space division manner (i.e., the time-frequency resource intersection between layers RI1 and RI2 is non-empty and / or the time-frequency resource difference set between layers RI1 and RI2 is empty), in a frequency division manner (i.e., the time-frequency resource difference set between layers RI1 and RI2 is empty and the frequency domain resource intersection between layers RI1 and RI2 is empty, i.e., PMI1 and PMI2 correspond to different CSI-RS resources and frequency domain resources, or, i.e., one CQI is formed by corresponding PMI and RI on different frequency domain resources), or in a time division manner (i.e., the time-frequency resource intersection between layers RI1 and RI2 is empty). The CQI is obtained based on the assumption and fed back to the base station, and if the assumption is different, the feedback CQI may be different. Furthermore, in the case of repetitive transmission in the spatial division manner, the CQI corresponding to the case where layer RI1 and layer RI2 correspond to the same channel scrambling sequence is different from the CQI corresponding to the case where layer RI1 and layer RI2 correspond to different channel scrambling sequences.

[0409] In the above description, the CQI is obtained based on the assumption of the scheme of transmission between different layer groups corresponding to the two combinations (PMI, RI). It is also possible to obtain the corresponding CQI based on the assumption of whether the scheme of transmission between different layer groups transmitted by the same RI of the same CSI-RS resource is repetitive. Here, one layer corresponds to one column of the precoder matrix indicator (PMI). The PMI is a matrix of the number of CSI-RS ports by RI, where RI indicates the number of layers.

[0410] Similarly, in the process of obtaining CQI for one CSI-RS resource, it is necessary to assume aggregation, i.e., time-domain repetition transmission rate, i.e., different CQIs may be fed back in response to different numbers of repetitions in the time domain when the PDSCH is transmitted. For the same tier group, different CQIs may be fed back in response to different time-domain repetition rates.

[0411] Similarly, different CQIs may be fed back in response to different redundancy versions used in the repeat transmissions.

[0412] Similarly, during repeated transmissions, the CQI obtained based on the same modulation order over different repeated transmissions may be different from the CQI obtained based on different modulation orders over different repeated transmissions. It is required to obtain the CQI based on whether the modulation order over different repeated transmissions is the same.

[0413] Similarly, during a repeated transmission, a CQI obtained based on the same channel code rate across different repeated transmissions may be different from a CQI obtained based on a different channel code rate across different repeated transmissions. It is required to obtain a CQI based on whether the channel code rate across different repeated transmissions is the same.

[0414] For example, the terminal obtains the CQI according to at least one of the repetition transmission rate or the repetition transmission mode in the following manner: the terminal stores a SINR-BLER mapping curve corresponding to each CQI index for each of at least one of the repetition transmission rate or the repetition transmission mode based on the receiving algorithm of the terminal. For a fixed CQI index, the SINR-BLER mapping curve varies with at least one of the repetition transmission rate or the repetition transmission mode. As shown in Figure 25, each horizontal coordinate indicates a SINR, each vertical coordinate indicates a BLER, and based on one CQI, the SINR-BLER mapping curve varies with the repetition transmission rate. When the terminal obtains a SINR based on the measurement reference signal, the terminal searches for a SINR-BLER mapping curve of each MCS corresponding to at least one of the currently assumed repetition transmission rates or repetition transmission modes, searches for a CQI index with a BLER less than 0.1 (or 0.00001) along with the currently obtained SINR based on the measurement reference signal, and then uses the smallest one of these CQI indices as the current CQI.

[0415] 26, another embodiment of the present application provides a feedback information sending device. The device includes: an obtaining module 2501 and a CQI information sending module 2502.

[0416] The obtaining module 2501 is configured to obtain channel quality indicator (CQI) information according to at least one of a repetition transmission rate R or a repetition transmission mode.

[0417] The CQI information transmitting module is configured to transmit the CQI information.

[0418] In this embodiment of the present application, the repeat transmission mode includes one of the following modes:

[0419] The R layer groups correspond to the R spatial domain resources.

[0420] The R tier groups correspond to R frequency domain resource groups, and the intersections between different frequency domain resource groups are empty.

[0421] The R tier groups correspond to R time domain resource groups, and the intersections between different time domain resource groups are empty.

[0422] The R repeated transmissions correspond to a redundancy version (RV) sequence.

[0423] The data channels corresponding to the R tier groups include repeated transmissions of the same information, where R is a positive integer greater than or equal to 2.

[0424] The R tier groups or one CQI information corresponds to at least one of A channel state information reference signal (CSI-RS) resources, A ranking indicator (RI) information, A precoder matrix indicator (PMI) information, A quasi-co-located reference signal sets (the A quasi-co-located reference signal sets may also be referred to as A TCI states, and one TCI state includes one quasi-co-located reference signal set), or A column groups of one PMI (one column of one PMI matrix corresponds to one tier).

[0425] A is equal to 1 or A is equal to R.

[0426] In this embodiment of the present application, the repetition rate R satisfies at least one of the following characteristics:

[0427] When R is 2 or more, one piece of transmission information is repeatedly transmitted on R resources.

[0428] When R is equal to 1, one transmission is not transmitted repeatedly.

[0429] The R resources correspond to at least one of R time domain resources, R spatial domain resources, R frequency domain resources, R reference signal (RS) resources, R quasi-co-located reference signal (RS) sets, R RVs, R scrambling sequences, or R tier groups.

[0430] In this embodiment of the present application, the CQI information is obtained according to at least one of a repetition transmission rate or a repetition transmission mode. This transmission scheme is closer to the actual PDSCH transmission scheme, thereby enabling the CQI to be fed back more accurately, improving the spectrum efficiency and reducing the interference. Furthermore, the implementation complexity of the base station is reduced, because the base station does not need to calculate the CQI actually used in the PDSCH transmission based on the CQI fed back by the terminal. In this calculation process, the different implementation algorithms between the base station and the terminal will lead to inaccurate calculation.

[0431] Another embodiment of the present application provides a feedback information transmission apparatus, the apparatus including a processor and a computer-readable storage medium, the computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform any of the aforementioned feedback information transmission methods.

[0432] Another embodiment of the present application provides a computer-readable storage medium storing a computer program which, when executed by a processor, causes the processor to perform the steps of any of the above-mentioned feedback information transmission methods.

[0433] In the NR protocol of the related art, when a dedicated PUCCH resource is not configured, the PUCCH resource is calculated according to CCE. Since the system information block (SIB) message notified by the SSB is consistent, the CORESET0, search space (SS)0, and common PUCCH resource corresponding to the two TRPs are the same. In particular, when there is no ideal backhaul between the two TRPs, if the two TRPs transmit PDCCHs independently of each other on CORESET0, the PUCCH resources of the HARQ-ACK of the PDSCHs scheduled by the PDCCHs of different TRPs may collide.

[0434] Another embodiment of the present application provides an information determining method, the method including at least one of the following steps:

[0435] A synchronization signal block (SSB) corresponding to one physical cell identifier (ID) is divided into E SSB groups, where E is a positive integer.

[0436] At least one of the following information is obtained according to the SSB group index: an uplink control channel resource where Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information is located, a Physical Random Access Channel (PRACH) resource, or Timing Advance (TA) information.

[0437] In this embodiment of the present application, the uplink control channel resource is obtained according to the SSB group index in the following manner.

[0438] One uplink control channel resource is selected from the uplink control channel resource group corresponding to the SSB group, and different SSB group indexes correspond to different uplink control channel resource groups.

[0439] In this embodiment of the present application, different SSB group indexes correspond to different uplink control channel resource groups in the following manner.

[0440] The frequency domain resource and / or time domain resource intersection between different uplink control channel resource groups corresponding to different SSB groups is empty.

[0441] The present embodiment enables independent scheduling of users based on the SSB group index.

[0442] (Embodiment 6) In this embodiment, a synchronization signal block (SSB) / physical broadcast channel (PBCH) in one physical cell is divided into multiple groups. Furthermore, at least one of the following enhancements may be implemented:

[0443] Enhancement 1: An SSB group index is introduced in the acquisition of PUCCH resources. In the NR protocol of the related art, when a dedicated PUCCH resource is not configured, the PUCCH resource is calculated according to CCE. Since the system information block (SIB) message notified by the SSB is consistent, the CORESET0, search space (SS)0, and common PUCCH resources corresponding to the two TRPs are the same. In particular, when there is no ideal backhaul between the two TRPs, if the two TRPs transmit PDCCH independently of each other on CORESET0, the PUCCH resources of the HARQ-ACK of the PDSCH scheduled by the PDCCH of different TRPs may collide. To enable the two TRPs to schedule users independently of each other, it is feasible to classify the SSBs into multiple groups and introduce the SSB group index in the acquisition of PUCCH resources, so that the two SSB group indexes correspond to different PUCCH resources. For example, the frequency domain resource and / or time domain resource intersection between different PUCCH resource groups corresponding to different SSB groups is empty. That is, two common PUCCH resource groups are available and correspond to two TRPs. As shown in Figure 27, different SSB groups of one physical cell correspond to different PUCCH resources, and HARQ-ACK of PDSCH scheduled by PDCCH in CORESET0 / SS0 in different SSB groups is fed back in one PUCCH resource selected from their respective PUCCH resource groups. In one embodiment, SIB messages signaled in different SSB groups are the same, but time domain resources and / or frequency domain resources occupied by different PUCCH resource groups are obtained according to SSB group index, or SIB messages signaled in different SSB groups may be different.

[0444] Extension 2: The physical random access channel (PRACH) resource acquisition parameters include an SSB group index, so that different TRPs correspond to different PRACH resource information.

[0445] Extension 3: When the terminal selects an SSB, the terminal may select one SSB from each of the two SSB groups. When the preamble is transmitted, the preamble is transmitted on the PRACH resource corresponding to only one SSB. msg3 further includes the SSB index selected from another SSB.

[0446] Extension 4: One SSB group corresponds to one TA information. Different SSB groups correspond to different TA information.

[0447] In the above scheme, the SSB group index information may be carried in the DMRS sequence information of the PBCH, or the SSB group information may be signaled in the PBCH / SIB.

[0448] Another embodiment of the present application provides an information determining apparatus, the apparatus including at least one of a grouping module or an information obtaining module.

[0449] The grouping module is configured to divide synchronization signal blocks (SSBs) corresponding to one physical cell ID into E SSB groups, where E is a positive integer.

[0450] The information obtaining module is configured to obtain at least one of an uplink control channel resource, a physical random access channel (PRACH) resource, or timing advance (TA) information where a hybrid automatic repeat request-acknowledgement (HARQ-ACK) is located according to the SSB group index.

[0451] In this embodiment of the present application, the uplink control channel resource is obtained according to the SSB group index in the following manner.

[0452] One uplink control channel resource is selected from the uplink control channel resource group corresponding to the SSB group, and different SSB group indexes correspond to different uplink control channel resource groups.

[0453] In this embodiment of the present application, different SSB group indexes correspond to different uplink control channel resource groups in the following manner.

[0454] The frequency domain resource and / or time domain resource intersection between different uplink control channel resource groups corresponding to different SSB groups is empty.

[0455] Another embodiment of the present application provides an information determination apparatus, the apparatus including a processor and a computer-readable storage medium, the computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform any of the above-mentioned information determination methods.

[0456] Another embodiment of the present application provides a computer readable storage medium storing a computer program which, when executed by a processor, causes the processor to perform the steps of any of the above-mentioned information determining methods.

[0457] Another embodiment of the present application provides a monitoring opportunity determination method, the method including: determining a monitoring opportunity of a downlink control channel scrambled by a Cell Radio Network Temporary Identifier (C-RNTI) in CORESET0 according to a synchronization signal block (SSB) index corresponding to at least one quasi-co-located reference signal set configured or activated for a control resource set CORESET0.

[0458] (Embodiment 7) In this embodiment, two or more quasi-co-located reference signal sets, such as two or more TCI states, are configured or activated for CORESET0. Each TCI state includes one quasi-co-located reference signal set. A monitoring opportunity of a PDCCH scrambled by a cell radio network temporary identifier (C-RNTI) in CORESET0 is determined according to an SSB index corresponding to the two or more quasi-co-located reference signal sets. For example, the monitoring opportunities of CORESET0 corresponding to SSBi are ii=0, 1, . . . , 63. When two SSBs {SSB1, SSB4} are configured or activated for CORESET0, the terminal monitors the PDCCH scrambled by the C-RNTI only in monitoring opportunity 1 and monitoring opportunity 4. When one SSB {SSB52} is configured or activated for CORESET0, the terminal monitors the PDCCH scrambled by the C-RNTI only in monitoring opportunity 52.

[0459] Furthermore, the SSB indices having a QCL relationship with the CSI-RS / SSB associated with Type-D included in two or more TCI states are different. Quasi-colocated reference signals associated with different quasi-colocation parameters in one TCI state and the same SSB index satisfy the QCL relationship for the corresponding quasi-colocation parameter.

[0460] Furthermore, the SSB index corresponding to the TCI state / quasi-collocated reference signal pair is an SSB index that satisfies a QCL relationship with the quasi-collocated reference signal in the TCI state / quasi-collocated reference signal pair.

[0461] Two or more quasi-co-located reference signal sets are configured for CORESET0 for a terminal, thereby enabling the terminal to detect control channels in CORESET0 corresponding to more SSBs, thereby improving resource utilization of CORESET0 (e.g., an idle CORESET0 can be used for transmission of a dedicated control channel) and improving performance of the dedicated control channel and / or common control channel.

[0462] An embodiment of the present application provides a monitoring opportunity determination device, which includes a monitoring opportunity determination module configured to determine a monitoring opportunity of a downlink control channel scrambled by a Cell Radio Network Temporary Identifier (C-RNTI) in CORESET0 according to a synchronization signal block (SSB) index corresponding to at least one quasi-co-located reference signal set configured or activated for a control resource set CORESET0.

[0463] Another embodiment of the present application provides a monitoring opportunity determination apparatus, the apparatus including a processor and a computer-readable storage medium, the computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform any of the above-mentioned monitoring opportunity determination methods.

[0464] Another embodiment of the present application provides a computer readable storage medium storing a computer program which, when executed by a processor, causes the processor to perform the steps of any of the above-mentioned monitoring opportunity determination methods.

[0465] (Embodiment 8) In this embodiment, the transmission information contained in one transport block (TB) as a whole does not correspond to one cyclic redundancy check (CRC) but is divided into multiple code blocks (CBs). Each CB has a CRC. The CBs are channel coded, cascaded, modulated, and then transmitted. In this way, when ultra-reliable low latency communication (URLLC) information occurs during the transmission of high speed large capacity communication (eMBB) traffic, some of the code block groups (CBGs) in the eMBB can be replaced by the CBGs of the new URLLC traffic. In this case, if all CBGs are transmitted correctly, there is no need for repeated transmission. If one TB as a whole has one CRC in addition to one CRC in each CB of the TB, the CRC of the TB as a whole fails after the CBGs of the new URLLC traffic replace some of the eMBB traffic, and the terminal feeds back a NACK, leading to repeated transmission of all data.

[0466] Further, it is executable to determine whether the transmission information contained in one TB as a whole has one CRC or does not comply with the signaling information and / or the predetermined rules.

[0467] According to the above scheme, one TB can contain both URLLC traffic data and eMBB traffic data, and not only can the DCI load be reduced, but also the suddenly occurring URLLC traffic data can be allowed to be inserted into one CBG of eMBB traffic.

[0468] (Embodiment 9) In this embodiment, the power difference between the DMRS and the PDSCH is determined according to the antenna group information and / or the TCI group information. Whether the power difference between the DMRS and the PDSCH is determined according to the CSI-RS information is determined according to the antenna group information and / or the TCI group information.

[0469] Furthermore, when the group information including CSI-RS and DMRS / PDSCH satisfies a predetermined condition, the power difference between DMRS and PDSCH may be determined according to the number of REs occupied by CSI-RS in one OFDM symbol. In one OFDM symbol, the more the number of REs occupied by CSI-RS that meet the condition, the larger the power difference between DMRS and PDSCH.

[0470] Furthermore, the time domain symbol in which the CSI-RS is located does not include the DMRS.

[0471] Further, the CSI-RS includes at least one of a non-zero power CSI-RS (NZP-CSI-RS), a zero power CSI-RS (ZP-CSI-RS), or an interference measurement CSI-IM resource.

[0472] Furthermore, the group information is group information including a reference signal and included in a TCI state corresponding to CSI-RS and DMRS / PDSCH; or the group information is information about a transmitting antenna group or a receiving antenna group corresponding to CSI-RS and DMRS / PDSCH.

[0473] The group information including the CSI-RS and the DMRS / PDSCH satisfies a predetermined condition in one of the following manners: the CSI-RS and the DMRS / PDSCH are in the same group; or the CSI-RS and the DMRS / PDSCH are in different groups.

[0474] When the transmitting antennas of CSI-RS and DMRS / PDSCH are different, DMRS / PDSCH cannot be transmitted on the REs occupied by CSI-RS on the transmitting antennas of DMRS / PDSCH, and the power transmitted on these REs can be used for power expansion of DMRS / PDSCH, so that not only is the transmitted power substantially equal in different time domain symbols, but the receiving performance of DMRS / PDSCH is also improved.

[0475] (Embodiment 10) In this embodiment, the terminal reports the maximum supported number of TCI state groups including TCI states activated for PDSCH in one BWP, and the TCI state groups are configured through MAC-CE signaling from the base station. For example, if different TCI state groups correspond to different TRPs or different receiving antennas of the terminal, the more TCI state groups are activated, the more receiving antennas the terminal needs to activate, and the more power the terminal consumes. The terminal reports this capability information to the base station.
