Abstract
Description
[0001] This application is a divisional application of the patent application with the application date of February 15, 2019, application number 201910117676.1, and invention title of "A Method and Device for Transmitting Information". Technical Field
[0002] Embodiments of the present invention relate to, but are not limited to, communication technologies, and in particular to a method for determining information, a device for determining information, and a storage medium. Background Art
[0003] In the relevant New Radio Access Technology (NR) protocol, dynamic switching of Transmission Reception Points (TRPs) is supported, enabling multiple TRPs to serve a terminal in a time-division manner to improve spectral efficiency or link robustness. However, it does not support multiple TRPs serving a terminal simultaneously on the same time-domain resource. To increase the flexibility of base station deployment and reduce link latency, it is necessary to consider the mechanism of multiple TRPs serving a terminal simultaneously on the same time-domain resource, or support the scenario where multiple TRPs can schedule the same user relatively independently without an ideal backhaul between them. Multiple TRPs serving the same user can improve spectral efficiency while increasing link robustness. However, how to enable the system of multiple TRPs serving the same user to work effectively is the main issue considered in this article.
[0004] Specifically, in the relevant NR protocol, up to 8 logical channels and 8 Logical Channel Groups (LCGs) are configured for a terminal. Among them, one logical channel corresponds to one Scheduling Request (SR) configuration, that is, one SR Identify (SRID). One SRID can correspond to multiple Physical Uplink Control Channel (PUCCH) resources in multiple Bandwidth Parts (BWPs) / Component Carriers (CCs), but one SRID can only correspond to one PUCCH resource in one BWP. One LCG can only correspond to one Buffer state at a time, that is, one LCG can only correspond to one Buffer size at a time to feedback the amount of new data to be transmitted corresponding to the LCG.
[0005] When a UE is served by two TRPs, for example, a terminal can send a Physical Uplink Shared Channel (PUSCH) to two TRPs in a time unit or on the same time-domain resource. Especially when there is no ideal backhaul between these two TRPs, the relevant SR request mechanism and the method of sending buffer state need to be enhanced so that a terminal can communicate with two TRPs through two uplink links in a BWP.
[0006] On the other hand, when multiple TRPs independently schedule a user respectively, how to reduce signaling overhead and increase the flexibility of parameters is also an issue considered in this paper.
[0007] Secondly, when two TRPs send PDSCH to a terminal and send the same data information on the two TRPs, how to enhance the feedback of Channel State Information (CSI) to improve the link robustness of serving the terminal by the two TRPs and improve the system spectrum efficiency at the same time is also a problem to be solved in this paper.
[0008] Thirdly, when there are two relatively independent TRPs in a cell, there is no ideal backhaul between the two TRPs, the two TRPs share a physical cell ID, but can schedule users relatively independently. At this time, how to reduce the signal interference between the two TRPs is also an issue considered in this paper. Summary of the Invention

[0335] Embodiments of the present invention implement the transmission of SR information or cache status information based on the first type of information, thereby enabling communication to be maintained with at least one uplink and at least one TRP.
[0336] Embodiment 1
[0337] In this embodiment, there are two Transmission Receive Points (TRPs) serving a terminal 1. In particular, when there is no ideal backhaul between the two TRPs, as Figure 3 shown, both TRP0 and TRP1 can schedule the uplink and downlink resources of terminal 1. TRP0 sends downlink control information (DCI) 0 on downlink (DL) 0, and this DCI0 is used to schedule terminal 1 to send a Physical Uplink Shared Channel (PUSCH) 0 on uplink (UL) 0 through panel 1; TRP1 sends DCI1 on DL1, and this DCI1 is used to schedule terminal 1 to send PUSCH1 on UL1 through panel 2; where PUSCH0 and PUSCH1 belong to the same Component Carrier (CC), even the same Bandwidth Part (BWP), and even the intersection of the time-domain resources occupied by PUSCH0 and PUSCH1 is non-empty, but the intersection of the frequency-domain resources occupied is empty, that is, frequency-division, or the intersection of the time-domain resources occupied by PUSCH0 and PUSCH1 is non-empty and the intersection of the frequency-domain resources occupied is also non-empty, that is, space-division.
[0338] To reduce the complexity of the terminal, the two TRPs share a Media Access Control (MAC) entity of the UE, that is, multiple TRPs correspond to one Serving Cell Group (SCG). Under this assumption, the main problem to be solved in this embodiment is to enable the terminal to communicate with the two TRPs on the two ULs relatively independently at the same time. One or more of the following enhanced solutions can be adopted to reduce the communication between TRPs while improving resource utilization or link robustness.
[0339] In the following description, as Figure 4As shown, the Hybrid Automatic Repeat Request Acknowledge (HARQ-ACK) 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 the respective TRP in different PUCCH resources, and the Channel State Information (CSI) of the PDCCH scheduled in different downlink control channel resources is fed back to the respective TRP in different PUCCH resources. The periodic CSI / SR corresponding to different TRPs is also fed back to the respective TRP in different PUCCH resources. In short, the HARQ-ACK, CSI, and SR corresponding to different TRPs cannot be combined and sent in one PUCCH resource, unless there is an ideal backhaul between these two TRPs. Specifically, for example, the CSIi, HARQ-ACKi, and SRi sent to TRPi can be combined and sent in one PUCCH resource. When i is not equal to j, {CSIi, HARQ-ACKi, SRi} and {CSIj, HARQ-ACKj, SRj} cannot be combined and sent in one PUCCH resource, where i, j = 0, 1. At most C PUCCH resources in a PUCCH resource group include HARQ-ACK in one time unit, where the value of C is equal to 1 or 2. When the value of C is equal to 1, the different PUCCH resources corresponding to the HARQ-ACK included in one time unit belong to different PUCCH resource groups. The PUCCH resources in a PUCCH resource group can only be time-division multiplexed, and the PUCCH resources in different PUCCH resource groups can be frequency-division multiplexed or space-division multiplexed. 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, it is equivalent to having an ideal backhaul between the TRPs. When i is not equal to j, {CSIi, HARQ-ACKi, SRi} and {CSIj, HARQ-ACKj, SRj} can be combined and sent in one PUCCH resource.
[0340] Enhanced Solution 1: One Scheduling Request configuration corresponds to N PUCCH resources (i.e., N scheduling request resources) in one BWP. As Figure 5As shown, one SR configuration corresponds to one SR identification number (SRID). One SRID configures two PUCCH resources in one BWP: {PUCCH0, PUCCH1}; among them, different PUCCH resources correspond to different TRPs. PUCCH0 comes from PUCCH resource group 0, and PUCCH0 corresponds to TRP0. PUCCH1 comes from PUCCH resource group 1, and PUCCH1 corresponds to TRP1. That is to say, one SRID corresponding to one logical channel or one logical channel group corresponds to N PUCCH resources in one BWP, where N is a positive integer greater than or equal to 1. For example, when there is only one TRP, N = 1 can be configured. When there are 2 TRPs, N can be configured to be greater than 1;
[0341] Preferably, the reference signal port group of the N PUCCH resources corresponding to one SR configuration (where the reference signal port group includes the reference signal port of PUCCH format 0 and / or the demodulation reference signal port group under other PUCCH formats) is not code-division. Further, the intersection of the time-domain resources and / or frequency-domain resources occupied by the N PUCCH resources is empty.
[0342] Alternatively, one SR configuration corresponds to one PUCCH resource in one BWP. Among the N reference signal port groups corresponding to the one PUCCH resource (i.e., the N scheduling request resources), each reference signal port group corresponds to one spatial transmission filter, that is, corresponds to one spatial relationship indication information. The reference signal ports in the same reference signal port group correspond to the same spatial relationship indication information. For example, different reference signal ports in the same reference signal port group use the same radio frequency beam and different digital beams, and the reference signal ports in different reference signal port groups use different spatial transmission filters. Preferably, the different reference signal port groups are not code-division, that is, they are frequency-division or time-division.
[0343] Alternatively, one SR configuration corresponds to one PUCCH resource in one BWP. The one PUCCH resource corresponds to one reference channel port group, and the one reference signal port group corresponds to N spatial relationship indication information, that is, one DMRS port corresponds to N spatial filters (i.e., the N scheduling request resources).
[0344] Alternatively, an SR configuration corresponds to a PUCCH resource in a BWP, and the PUCCH resource corresponds to N frequency-domain resource groups and / or time-domain resource groups (i.e., the N scheduling request resources), and the frequency-domain resource group and / or time-domain resource group corresponds to a spatial relation indication information.
[0345] The above is that one SR ID corresponds to N scheduling request resources, where the scheduling request resources include at least one of the following: a PUCCH resource, a reference signal port group of a PUCCH resource, a time-domain resource group of a PUCCH resource, a frequency-domain resource group of a PUCCH resource, a time-frequency resource group of a PUCCH resource. The buffers corresponding to the N scheduling request resources can be different. Specifically, as Figure 5 shown, two scheduling request resources (such as the PUCCH resource in Figure 5 ) respectively correspond to a buffer. The data in a logical channel or a logical channel group is divided into two parts and stored in Buffer1 and Buffer0 respectively. The difference set and / or intersection of the data information included in Buffer1 and Buffer0 is non-empty. Different buffers are sent to different TRPs. The states of whether there is data in these two buffers can be the same, such as either both being positive SR or both being negative SR, or they can be different, such as only one being positive SR, that is, there is only one buffer with new data to be sent. The data of an LCG is divided into two buffers according to the signaling information sent by the base station and / or as a terminal implementation behavior.
[0346] Or as Figure 6 shown, two scheduling request resources (such as the PUCCH resource in Figure 6 ) correspond to the same buffer. For these N scheduling request resources, either all are positive SR or all are negative SR. In short, the SR information corresponding to this buffer is sent to multiple TRPs to improve the success rate and robustness of SR transmission. Or the terminal selects one or more of these N scheduling request resources to send the SR information corresponding to this buffer. For example, it selects a PUCCH resource with low transmission power to send this SR information to reduce the terminal's transmission power consumption. After sending this SR information, communication can be carried out between two TRPs to determine which TRP the terminal should send PUSCH to, that is, whether to send data using PUSCH0, or using PUSCH1, or using PUSCH0 and PUSCH1 simultaneously.
[0347] Enhanced Solution 2: As Figures 7 - 8 shown, one logical channel corresponds to L SRIDs, where L is a positive integer greater than or equal to 1. One SRID corresponds to one PUCCH resource in one BWP, which also makes one logical channel associated with more than one PUCCH resource in one BWP.
[0348] Similar to Enhanced Solution 1, the SR information corresponding to these L SRIDs can be the same or different. As Figure 7 shown, the L SRIDs correspond to L Buffers. Figure 7 Taking L as 2 as an example, the SR information corresponding to the two Buffers can be the same. For example, either both Buffers have data to be sent or neither of them has data to be sent. The L SRIDs can be triggered simultaneously or independently. For example, only some of the Buffers have data to be sent. Or, as Figure 8 shown, the L SRIDs correspond to the same Buffer. At this time, the SR information corresponding to the L scheduling request resources corresponding to the L SRIDs is consistent. The SR resources corresponding to the L SRIDs can be triggered simultaneously. The terminal sends one SR information to different TRPs through multiple links to increase the transmission robustness of the SR. Or, a positive SR information can be sent on the scheduling request resources corresponding to some of the L SRIDs.
[0349] Enhanced Solution 3: One LCG corresponds to M buffer states. As Figure 9As shown in the figure, different buffer states correspond to different TRPs and different Buffers. Different buffer state reports are included in different MAC-CE commands and sent in different PUSCHs. For example, when there is data to be transmitted at the terminal side in an LCG, the data in the LCG is divided into two parts and transmitted to different TRPs respectively. That is, in the buffer state reports included in different PUSCHs, the buffer size corresponding to an LCG can be different. For example, in the buffer state report in PUSCH0, the buffer size of LCG1 is 1200 bit, and in the buffer state report in PUSCH1, the buffer size of LCG1 is 800 bit. It can also be that the buffer size of LCG1 in both PUSCH0 and PUSCH1 is 1000, but after the buffer state report is sent, the 1000-bit information of LCG1 transmitted to different TRPs is independent and corresponds to Buffer0 and Buffer1 respectively. It can also be that the difference set of the 1000-bit information of LCG1 transmitted to different TRPs is empty, that is, the same data is sent to different TRPs on two uplink channels, which increases the robustness of the link and is also suitable for relatively independent scheduling of multiple TRPs. Preferably, PUSCH0 and PUSCH1 respectively correspond to two types of PUSCHs, corresponding to two sets of uplink data channel process numbers, and are respectively scheduled by the control channel resources in different downlink control channel resource groups. Different downlink control channel resource groups correspond to different TRPs.
[0350] Or as Figure 10 shown in the figure, an LCG corresponds to M buffer states. Different buffer states correspond to different TRPs and the same Buffer. Different buffer state reports are included in the PUSCHs in different MAC-CE commands and sent.
[0351] Enhanced solution 4: As Figure 11 shown in the figure, the SRIDs under a serving cell group (SCG) are divided into two groups (i.e., the X SRID groups), and each SRID group corresponds to a TRP. Different SRID groups correspond to different TRPs.
[0352] Among them, the intersection between the SRIDs corresponding to different SRID groups can be non-empty or empty.
[0353] Among them, each SRID group corresponds to a TRP, and different SRID groups corresponding to different TRPs include: each SRID group corresponds to a set of first - type parameters, and different SRID groups correspond to different first - type parameters; among them, the first - type parameters include at least one of the following: PUCCH resource group, one type of PUSCH (for example, 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 state group, spatial relationship indication information group; one SRID corresponds to one or more of the said logical channels. For example, there are a total of 8 SRIDs, which are divided into two groups. SRID group 1 includes {SRID0 - SRID3}, and SRID group 2 includes {SRID4 - SRID7}. The SR information corresponding to the logical channels corresponding to the SRIDs in SRID group 1 can be combined and fed back in one PUCCH resource / PUSCH, and the SR information corresponding to the logical channels corresponding to the SRIDs in different SRID groups cannot be combined and fed back in one PUCCH resource / PUSCH. Here, "combination" means selecting one from the SR information in the positive state (i.e., positive SR information) in one SRID group for transmission. For example, when feeding back on PUCCH, when there are 3 SRIDs in the positive SR state among the SR information corresponding to the logical channels corresponding to the SRIDs in the same SRID group, one of the 3 SRIDs in the positive SR state is fed back on one PUCCH resource in the PUCCH resource group corresponding to this SRID group. When two SRIDs in the positive SR state belong to different SRID groups, they can only be fed back on two PUCCH resources, and the two PUCCH resources belong to different PUCCH resource groups respectively.
[0354] Enhanced solution 5: Divide the LCG under one SCG into Y LCG groups. As Figure 12 shown, divide the LCG under one SCG into two groups. Each LCG group corresponds to a TRP, and the intersection between the LCGs corresponding to different LCG groups can be non - empty or empty. Each LCG group corresponds to a TRP, and different LCG groups corresponding to different TRPs include that each LCG group corresponds to a set of second - type parameters, and different LCG groups correspond to different second - type parameters. Of course, at this time, it can be further that Y LCG groups correspond to Y SRID groups, and the LCG groups and an SRID group are in one - to - one correspondence.
[0355] Among them, the second type of parameters includes at least one of the following: a type of PUSCH (for example, different types of PUSCH channels are scheduled by downlink control channels in different downlink control channel resource groups), downlink control channel resource groups, MAC CE including Buffer state report, Buffer size, TCI state group, spatial relation indication information group.
[0356] Among them, one LCG includes one or more of the above logical channels. For example, there are a total of 8 LCGs, which are divided into two groups. LCG group 1 includes {LCG0 - LCG3}, and LCG group 2 includes {LCG4 - LCG7}. PUSCH0 (the first type of PUSCH) includes the transmission information of the Buffer size corresponding to the LCGs in LCG group 1, and PUSCH1 (the second type of PUSCH) includes the transmission information of the Buffer size corresponding to the LCGs in LCG group 2. The Buffer state information in one LCG group can be merged and fed back in one PUSCH of the type of PUSCH corresponding to the LCG group. The Buffer state information in different LCG groups cannot be merged and fed back in one PUSCH, but can only be fed back in different types of PUSCH. Different types of PUSCH correspond to different TRPs and are scheduled by different control channel resources.
[0357] The above is described by taking two TRPs as an example, and this embodiment does not exclude the case of more than 2 TRP transmissions.
[0358] On the other hand, at least one of N, L, M, X, Y is related to the number of uplink control channel resource groups, and / or at least one of N, L, M, X, Y is related to the number of downlink control channel resource groups, and / or at least one of N, L, M, X, Y is related to the number of Transmission Configuration Indication (TCI) state groups, and / or at least one of N, L, M, X, Y is related to the number of spatial relation indication information groups, and / or the sum of at least two of N, L, M, X, Y is greater than 2. Among them, one TCI state includes the indication information of a set of quasi - co - located reference signals. Different TCI state groups correspond to downlink signals sent by different TRPs, and different spatial relation indication information groups correspond to downlink signals sent by different TRPs.
[0359] There is an association relationship between the above different PUCCH resource groups and different downlink control channel resource groups. In another implementation manner of this embodiment, there may also be a corresponding relationship 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. Determine the PUCCH resource group where the PUCCH resource where the HARQ-ACK corresponding to the PDSCH is located according to the TCI state group to which the TCI state of the PDSCH belongs. For example, if the TCI state of the PDSCH belongs to TCI state group 0, then the PUCCH resource group where the PUCCH resource where the HARQ-ACK corresponding to the PDSCH is located is PUCCH resource group 0. For example, if the TCI state of the PDSCH belongs to TCI state group 1, then the PUCCH resource group where the PUCCH resource where the HARQ-ACK corresponding to the PDSCH is located is PUCCH resource group 1.
[0360] Similarly, there may also be an association relationship between different PUCCH resource groups and different spatial relation indication information groups.
[0361] Similarly, there is an association relationship between different types of PUSCH and different TCI state groups, and / or there is a corresponding relationship between different types of PUSCH and different spatial relation indication information groups.
[0362] The above more than one LCG can all be dedicated traffic channels.
[0363] Embodiment 2
[0364] In this embodiment, determine the PUCCH resource where the HARQ-ACK of the SR and / or SPS-PDSCH is located. For example, according to a predetermined rule, determine that the HARQ-ACK of the SR and / or SPS-PDSCH is in the PUCCH resource of the PUCCH resource group with the lowest index (or the highest index); and / or according to a predetermined rule, determine that the HARQ-ACK of the SR and / or SPS-PDSCH is in the HARQ-ACK codebook of the HARQ-ACK code group with the lowest index (or the highest index); or determine the PUCCH resource where the SR is located according to the PUCCH resource group where the PUCCH resource configuring the SR is located.
[0365] Determine the PUCCH resource where the HARQ-ACK of the semi-persistent scheduled PDSCH is located and / or the HARQ-ACK codebook according to at least one of the following:
[0366] Solution 1: The downlink control channel resource group where the control channel for scheduling the semi-persistent downlink data channel is located, such as one uplink control channel resource in the uplink control channel resource group corresponding to the downlink control channel resource group where the DCI for scheduling the SPS-PDSCH is located and / or the PUCCH resource and / or HARQ-ACK codebook where the HARQ-ACK for the SPS-PDSCH is located;

[0371] When there is an SPS-PDSCH corresponding to a PDCCH (i.e., the first SPS-PDSCH transmission after the DCI activating the SPS-PDSCH), Solution 1 and / or Solution 2 can be adopted. When there is no SPS-PDSCH corresponding to a PDCCH, one of Solutions 3, 4, and 5 can be adopted, or when there is no SPS-PDSCH corresponding to a PDCCH and currently there is only SPS-PDSCH without other PDSCHs, Solution 3 is adopted. Otherwise, when there is no SPS-PDSCH corresponding to a PDCCH, one of Solutions 3, 4, and 5 can be adopted.
[0372] Further, according to the PUCCH resource group to which the PUCCH resource where the HARQ-ACK of SR and / or SPS-PDSCH is located belongs, determine the HARQ-ACK / CSI information that is merged with the HARQ-ACK of SR and / or SPS-PDSCH into one PUCCH resource or one type of PUSCH resource for feedback. At least two of the HARQ-ACK / CSI / SR / HARQ-ACK of SPS-PDSCH corresponding to the same PUCCH resource group can be merged into one PUCCH resource / one PUSCH for feedback; at least two of the HARQ-ACK / CSI / SR / HARQ-ACK of SPS-PDSCH corresponding to different uplink control channel resource groups need to be feedback in different PUCCH resources / different PUSCHs.

[0610] Activation or deactivation information of the half-period signal.
[0611] Further, obtaining another type of information according to one of the second type of information and the third type of information includes: determining the third type of information according to the number of the second type of information. Specifically, taking the number of the second type of information as the third type of information, or calculating the number of the second type of information according to a predetermined function relationship to obtain the third type of information. When the second type of information includes multiple pieces of information, the number of the second type of information may be the maximum value, minimum value, sum of all the numbers of the second type of information, or calculated according to other function relationships. The specific function relationship is not used to limit the protection scope of the embodiments of the present invention.
[0612] Further, determining the HARQ-ACK feedback codebook according to the second type of information includes at least one of the following:
[0613] Determining the number of HARQ-ACK feedback codebooks fed back in a time unit according to the second type of information; determining the number of HARQ-ACK feedback bits corresponding to a type of PDSCH divided by the end of the PDSCH in a HARQ-ACK feedback codebook; introducing a loop of the second type of information in the acquisition process of a HARQ-ACK feedback codebook.
[0614] Further, each piece of the second type of information corresponds to one piece of the third type of information; the signaling information includes a MAC-CE command; the signaling information is used to notify one of the second type of information and the third type of information; wherein, the signaling information includes the index information of the other type of information corresponding to the notified one of the information; the predetermined bit field in the DCI includes at least one of the following: a TCI field, a CSI request field, a sounding reference signal (SRS) request field, a PUCCH resource indication field;
[0615] Further, determining whether at least two of HARQ-ACK / SR / CSI can be combined and fed back in one PUCCH according to the second type of information includes at least one of the following:
[0616] At least two of (HARQ-ACK, SR, CSI) corresponding to the same second type of information can be combined and fed back in one PUCCH;
[0617] At least two of (HARQ-ACK, SR, CSI) corresponding to different second types of information cannot be combined and fed back in one PUCCH;
[0618] At least two of (HARQ-ACK, SR, CSI) corresponding to different second types of information are fed back in different PUCCHs;
[0619] Determine whether at least two of (HARQ-ACK, SR, CSI) corresponding to different second types of information can be combined and fed back in one PUCCH resource according to signaling information.
[0620] Specifically, as Figure 16 shown, for the TRPs corresponding to different second types of information, at least two of (HARQ-ACK, SR, CSI) corresponding to the same second type of information can be combined and fed back in one PUCCH resource / PUSCH, and at least two of (HARQ-ACK, SR, CSI) corresponding to different second types of information cannot be combined and fed back in one PUCCH resource / PUSCH; determine whether at least two of (HARQ-ACK, SR, CSI) corresponding to different second types of information can be combined and fed back in one PUCCH resource / PUSCH according to signaling information.
[0621] When determining the HARQ-ACK feedback codebook, a cycle of the second type of information can be introduced in the process of obtaining a HARQ-ACK feedback codebook. For example, the cycle for the second type of information can be placed at the end to obtain a HARQ-ACK feedback codebook. For example, the arrangement order of the feedback bits included in a HARQ-ACK feedback codebook is (the HARQ-ACK feedback bits corresponding to the PDSCH of the second type of information with T associated indexes 0 time-division multiplexed in the slot, the HARQ-ACK feedback bits corresponding to the PDSCH of the second type of information with T associated indexes 0 time-division multiplexed in the slot,..., the HARQ-ACK feedback bits corresponding to the PDSCH of the second type of information with T associated indexes 0 time-division multiplexed in the slot, the HARQ-ACK feedback bits corresponding to the PDSCH of the second type of information with T associated indexes 1 time-division multiplexed in the slot, the HARQ-ACK feedback bits corresponding to the PDSCH of the second type of information with T associated indexes 1 time-division multiplexed in the slot,..., the HARQ-ACK feedback bits corresponding to the PDSCH of the second type of information with T associated indexes 1 time-division multiplexed in the slot), or in a HARQ-ACK feedback codebook, the cycle of the second type of information is before the time-domain PDSCH cycle. For example, the arrangement order of the HARQ-ACK bits for the PDSCH in the first time-domain resource group in the slot is: (the HARQ-ACK feedback bits corresponding to the PDSCH of the second type of information with the associated index 0 in the first time-domain resource group in the slot, the HARQ-ACK feedback bits corresponding to the PDSCH of the second type of information with the associated index 1 in the first time-domain resource group in the slot), then the cycle of the time-domain resource groups in the slot, and then the cycle of the slot. Among them, \(n_1,n_2,\cdots\) represent the slot indexes where the PDSCH corresponding to the HARQ-ACK to be fed back in slot \(n\) is located, and \(n_1,n_2,\cdots\) can be positive integers or fractions, such as when the subcarrier spacing of the PDSCH and the PUCCH is different).
[0622] Alternatively, obtain a HARQ-ACK code book for each different type of second-class information respectively, that is, determine the number of HARQ-ACK feedback code books according to the number of types of second-class information configured for the terminal. When one type of second-class information is configured for the terminal, it indicates that there is only one TRP, or the two TRPs have an ideal backhaul. In this case, only one HARQ-ACK feedback code book needs to be fed back in one time unit. When more than one type of second-class information is configured for the terminal, it indicates that there are multiple TRPs. In particular, it is possible that there is no ideal backhaul between the TRPs, or the TRPs can schedule users independently. Therefore, a HARQ-ACK feedback code book needs to be sent to each different TRP respectively. The HARQ-ACK feedback code book is for the HARQ-ACK information of the PDSCH from the TRP (i.e., associated with the second-class information).
[0623] Further, it is possible to determine whether the HARQ-ACK code books corresponding to different indexes of the second-class information can be merged and fed back in one PUCCH resource / PUSCH according to the signaling information. When merging, the HARQ-ACK code books can be linked according to the indexes of the second-class information. For example, the HARQ-ACK code book corresponding to the second-class information with index 0 is followed by the HARQ-ACK code book corresponding to the second-class information with index 1. These two merged HARQ-ACK code books are input into the channel encoder for encoding. After encoding, they are fed back in one PUCCH resource.
[0624] Further, as Figure 15 shown, in one TRP, a HARQ-ACK code book is obtained respectively for ultra-reliable low-latency (URLLC, UltraReliable Low Latency Communication) services and enhanced mobile broadband (eMBB, Enhanced Mobile Broadband) services. A HARQ-ACK code book needs to be obtained respectively for different types of second-class information and different service types. As Figure 16As shown, the second type of information with index 0 corresponds to TRP0, and the second type of information with index 1 corresponds to TRP1. Under each TRP, two HARQ-ACK codebooks are obtained for different service types. If there are two pieces of the second type of information with different service types, there may be 4 HARQ-ACK codebooks in one slot. Among them, HARQ-ACK codebook 1 and HARQ-ACK codebook 2 are fed back to TRP0, and 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 according to the number of the second type of information, where the one slot is the slot where the resource (PUCCH / PUSCH) for feeding back HARQ-ACK is located.
[0625] Or when there is an ideal Backhaul between two TRPs, these 4 HARQ-ACK feedback codebooks can also be merged and fed back on one PUCCH resource. At this time, the merging order of these 4 HARQ-ACK codebooks needs to be determined. For example, the merging order is (HARQ-ACK codebook 1, HARQ-ACK codebook 3, HARQ-ACK codebook 2, HARQ-ACK codebook 4), that is, the HARQ-ACK feedback codebook for URLLC service is placed in the front because when channel coding, the reliability of the front bits is higher than that of the back bits in terms of channel reliability.
[0626] On the other hand, as Figure 16 shown, it is necessary to determine the maximum number of PDSCH / codewords (CW, Code Word) whose intersection of time-domain resources occupied in a BWP / CC is non-empty according to the second type of information. When one piece of the second type of information is configured, the maximum number of PDSCH / CWs whose intersection of time-domain resources occupied in a BWP / CC is non-empty belongs to {1, 2}. When 2 pieces of the second type of information are configured, the maximum number of PDSCH / CWs whose intersection of time-domain resources occupied in a BWP / CC is non-empty belongs to {1, 2, 3, 4}. Similarly, the number of uplink PUSCH / CWs that can be simultaneously transmitted on the same time-domain symbol can also be obtained according to the second type of information. The number of uplink PUSCH / CWs whose occupied time-domain resources have an intersection can also be obtained according to the second type of information.
[0627] In an embodiment of the present embodiment, determining the number of beam switches according to the TCI state group and / or antenna group includes that when the beams of two signals on different time domain symbols are different, that is, for example, the two signals do not satisfy the quasi-co-location relationship with respect to the spatial reception parameters, it is further necessary to determine whether a beam switch has occurred between the two signals according to the TCI state group and / or antenna group corresponding to the two signals. Specifically, when the TCI state group and / or antenna group corresponding to the two signals are different, no beam switch has occurred between the two signals, that is, the number of beam switches does not increase. Otherwise, a beam switch has occurred between the two signals, that is, the number of beam switches is incremented by 1. Because although the reception beams of the two signals are different, the two reception beams corresponding to the two signals correspond to two reception antennas, and these two reception antenna terminals are always in the on state. Therefore, even though the reception beams of the two signals are different, due to the different reception antennas, it is not counted as a beam switch. In short, the reception antenna groups corresponding to the two signals of the beam switch need to be the same. The above solution can be used in scenarios where the number of beam switches of a terminal in a limited time unit cannot exceed a predetermined threshold. Similarly, the number of beam switches can also be determined according to other second-type information.
[0628] The above is to determine the third-type information according to the second-type information, or it can also be to determine the second-type information according to the third-type information.
[0629] In another implementation manner of the present embodiment, a signaling message is transmitted, and the signaling message includes the second-type information and the third-type information. For example, the signaling message 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 the index information of the second-type information.
[0630] Specifically, as Figure 17 shown, in the MAC-CE command for notifying the mapping relationship between the TCI indication field and the TCI content in the DCI, it includes the second-type information index, such as the control channel resource group index, indicating that the MAC-CE command notifies the mapping relationship between the TCI indication field value in the DCI corresponding to the second-type information index and the TCI content indicated by the TCI indication field value. Figure 17 The Ti (i = 0, 1,..., 87) in it corresponds to a TCI state in the TCI state list notified by the RRC signaling. Ti = 1 indicates activating the TCI state, and Ti = 0 indicates deactivating the TCI state. The 8 values of the TCI indication field (bit 3-bit) in the DCI correspond one-to-one with the TCI states with Ti value of 1. For example, Figure 17Among them, the index of the control channel resource group is 0, and the Ti with a value of 1 is {T1, T9, T18, T20, T30, T32, T34, T87}. Then, the mapping table between the TCI bit field in the DCI in control channel resource group 0 and the indicated TCI content is shown in Table 1. The index of the control channel resource group is 1, and the Ti with a value of 1 is {T2, T11, T21, T24, T35, T37, T44, T80}. Then, the mapping table between the TCI bit field in the DCI in control channel resource group 1 and the indicated TCI content is shown in Table 2.
[0631] TCI bit field value Indicated TCI content 000 TCI state 1 001 TCI state 9 010 TCI state 18 011 TCI state 20 100 TCI state 30 101 TCI state 32 110 TCI state 34 111 TCI state 87
[0632] Table 1
[0633] TCI bit field value Indicated TCI content 000 TCI state 2 001 TCI state 11 010 TCI state 21 011 TCI state 24 100 TCI state 35 101 TCI state 37 110 TCI state 44 111 TCI state 80
[0634] Table 2
[0635] Figure 17 The MAC-CE command in it carries the downlink control channel resource group index. Of course, it can also be other second-type information mentioned above. For example, it is the TCI state group index, indicating which TCI state in the TCI state group the Ti corresponds to. The number of TCI states included in different TCI state groups can be different, so the number of Ti required can be different. For example, when it is TCI state group 0, Figure 17 there are 88 Ti bits. For example, when it is TCI state group 1, Figure 17 there are 48 Ti bits.
[0636] Similarly, Figure 17 the Ti in it can also correspond one-to-one with the aperiodic CSI trigger state, so that the mapping tables between the CSI request fields and the CSI indication contents in different DCIs corresponding to different second-type information are different.
[0637] Similarly, the configuration information of the request field of the aperiodic SRS (i.e., the sounding reference signal SRS request field) can carry the downlink control channel resource group index, which is used to determine the mapping relationship between the bit indication value of the aperiodic SRS request field in the DCI in the downlink control channel resource group and the indicated content of the aperiodic SRS. The DCIs in different downlink control channel resource groups can correspond to different mapping relationships between the bit indication value of the aperiodic SRS request field and the indicated content of the aperiodic SRS.
[0638] Similarly, the downlink control channel resource group index may also be carried in the configuration information of the SRS resource indication information of the DCI, which is used to determine the mapping relationship between the bit indication value of the SRS resource indication field of the DCI in the downlink control channel resource group and the indicated SRS resource. The DCI in different downlink control channel resource groups may correspond to different mapping relationships between the bit indication value of the SRS resource indication field and the indicated SRS resource. The SRS resource indication field includes those for indicating the spatial filter and / or precoding information and / or antenna port of the PUSCH. For example, it is used to indicate one or more SRS resources in the SRS set for which the purpose is codebook / non codebook. The spatial filter and / or precoding information and / or antenna port of the PUSCH are obtained according to the indicated SRS resource.
[0639] Similarly, the second type of information index may also be carried in the MAC-CE command for activating or deactivating the semi-periodic CSI-RS / CSI-IM, indicating which semi-periodic CSI-RS / CSI-IM corresponding to the second type of information the activation or deactivation of the semi-periodic CSI-RS / CSI-IM is.
[0640] Similarly, in the MAC-CE command for activating the spatial relationship of the PUCCH resource, a spatial relationship group index is carried as Figure 18 shown, which is used to indicate which spatial relationship in which spatial relationship group the si, i = 0, 1,..., 7 corresponds to. The number of spatial relationship indication information included in different spatial relationship groups may be different.
[0641] Embodiment 4
[0642] In this embodiment, a correspondence relationship between the downlink control channel resource group and the set of uplink data channel process numbers is established. For example, there are two downlink control channel resource groups, and different downlink control channel resource groups correspond to different TRPs. The sets of PUSCH process numbers corresponding to different downlink control channel resource groups are different. For example, the set of PUSCH process numbers corresponding to downlink control channel resource group 0 is {0 to 15}, and the set of PUSCH process numbers corresponding to downlink control channel resource group 1 is {16 to 31}. When the downlink control information (DCI, Downlink Control Information) scheduling the PUSCH in downlink control channel resource group 0 indicates a process number of 0, it corresponds to the absolute process number 0. When the DCI scheduling the PUSCH in downlink control channel resource group 1 indicates a process number of 0, it corresponds to the absolute process number 16.
[0643] Alternatively, different downlink control channel resources in two downlink control channel resource groups correspond to different sets of PDSCH process numbers, but correspond to the same set of PUSCH process numbers. For example, the set of PUSCH process numbers corresponding to downlink control channel resource group 0 is {0 to 15}, and the set of PDSCH process numbers is {0 to 15}; the set of PUSCH process numbers corresponding to downlink control channel resource group 1 is {0 to 15}, and the set of PDSCH process numbers is {16, 31}. When the process number indicated in the DCI for scheduling PUSCH in downlink control channel resource group 0 is 0, it corresponds to the absolute process number 0; when the process number indicated in the DCI for scheduling PDSCH in downlink control channel resource group 0 is 0, it corresponds to the absolute process number 0; when the process number indicated in the DCI for scheduling PUSCH in downlink control channel resource group 1 is 0, it also corresponds to the absolute process number 0; when the process number indicated in the DCI for scheduling PDSCH in downlink control channel resource group 1 is 0, it corresponds to the absolute process number 16.
[0644] In short, it is necessary to establish an association relationship between the downlink control channel resource group and at least one of the following information: the set of PUSCH process numbers, the set of PDSCH process numbers.
[0645] Alternatively, an association relationship exists between the TCI group / space relationship indication information group and at least one of the following information: the set of PUSCH process numbers, the set of PDSCH process numbers.

Specifically, use the number of the second - type information as the third - type information, or calculate the third - type information according to a predetermined function relationship for the number of the second - type information. When the second - type information includes multiple pieces of information, the number of the second - type information can be the maximum value, minimum value, sum of all the second - type information, or calculated according to other function relationships. The specific function relationship is not used to limit the protection scope of the embodiments of the present invention.
[0664] In an embodiment of the present invention, the second determination module 1801 is specifically configured to implement the determination of the HARQ - ACK feedback codebook according to the second - type information by using at least one of the following methods:
[0665] Determine the number of HARQ - ACK feedback codebooks in one time unit where the feedback resource falls according to the second - type information; wherein, the time unit can be one or more time slots;

[0668] In an embodiment of the present invention, the second determination module 1801 is specifically configured to implement determining whether at least two of HARQ-ACK, SR, and CSI can be included in one uplink channel for feedback according to the second type of information by using at least one of the following methods:

[0680] In the embodiment of the present invention, in a multi-TRP transmission scenario, an association is established between the second type of information and the third type of information, and one of the second type of information and the third type of information is used to obtain the other type of information, so that different second type of information corresponds to different third type of information. Since different second type of information corresponds to different TRPs, that is, different TRPs correspond to different third type of information. The second type of information and the third type of information are included in one signaling message, reducing the signaling overhead, thereby improving the parameter flexibility and the system performance.
[0681] Another embodiment of the present invention provides an information determination device, including a processor and a computer-readable storage medium. Instructions are stored in the computer-readable storage medium, and when the instructions are executed by the processor, any of the above information determination methods is implemented.
[0682] Another embodiment of the present invention provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of any of the above information determination methods are implemented.
[0683] See Figure 19 , another embodiment of the present invention provides a method for sending feedback information, including:
[0684] Step 1900, obtain Channel Quality Indicator (CQI) information according to at least one of the following information: repetition transmission factor R, repetition transmission mode.
[0685] In the embodiment of the present invention, the repetition transmission mode includes one of the following:
[0686] R layer groups correspond to R spatial domain resources;
[0687] R layer groups correspond to R frequency domain resource groups, and the intersection between different frequency domain resource groups is empty;
[0688] R layer groups correspond to R time domain resource groups, and the intersection between different time domain resource groups is empty;
[0689] Redundancy Version (RV) sequences corresponding to R repeated transmissions;
[0690] Wherein, the repeated transmissions of the same information are included in the data channels corresponding to the R layer groups, and R is a positive integer greater than 1.
[0691] Wherein, the R layer groups or one CQI information correspond to at least one of the following:
[0692] A channel state information-reference signal (CSI-RS) resource;
[0693] A rank indicator (RI) information;
[0694] A precoder matrix indicator (PMI) information;
[0695] A set of quasi co-located reference signals; wherein, the set of A quasi co-located reference signals may also be referred to as A TCI states, and a set of quasi co-located reference signals is included in one TCI state;
[0696] A column groups of a PMI, where one column of a PMI matrix corresponds to one layer;
[0697] Wherein A is equal to 1, or A is equal to R.
[0698] In an embodiment of the present invention, the repetition transmission factor R satisfies at least one of the following:
[0699] When R is greater than 1, a transmission information is repetitively transmitted on R resources;
[0700] When R is equal to 1, a transmission information is not repetitively transmitted;
[0701] Wherein, the R resources correspond to at least one of the following R: time domain resources, spatial domain resources, frequency domain resources, reference signal resources, quasi co-located reference signal sets, RV versions, scrambling sequences, layer groups.
[0702] In an embodiment of the present invention, determining CQI information includes:
[0703] Establishing a mapping relationship between the SINR and BLER corresponding to each repetition transmission factor and / or repetition transmission mode corresponding to each CQI information;
[0704] Obtaining the SINR based on the measurement reference signal;
[0705] Obtaining the mapping relationship between the SINR and BLER of each modulation and coding scheme (MCS) corresponding to the current repetition transmission factor and / or repetition transmission mode;
[0706] Obtaining the BLER corresponding to the SINR obtained based on the measurement reference signal in the obtained mapping relationship between the SINR and BLER;
[0707] Obtain the minimum value of the CQI information with a BLER less than a preset threshold.
[0708] Step 1901: Transmit the CQI information.
[0709] In the embodiments of the present invention, the CQI is obtained according to the repetition transmission factor and / or the repetition transmission mode, which is closer to the transmission scheme of the actually transmitted PDSCH, making the feedback CQI more accurate, thereby improving the spectral efficiency and reducing interference. On the other hand, it also reduces the implementation complexity of the base station because the base station does not need to convert the CQI actually used during PDSCH transmission based on the CQI feedback from the terminal, and inaccurate conversion may occur due to different implementation algorithms of the base station and the terminal during this conversion process.
[0710] Embodiment 5
[0711] In this embodiment, two TRPs simultaneously send the same PDSCH data to a terminal. For example, one DMRS port corresponds to two TCI states; or the same transmission information is transmitted on two DMRS ports, and the modulation order and / or channel coding rate corresponding to the two DMRSs can be the same or different. That is, data is repeatedly transmitted in a space division manner.
[0712] In order to enable the terminal to feedback accurate Channel Quality Indication (CQI), when the terminal feeds back, it is necessary to assume whether the intersection between the data from the two TRPs is empty or non-empty, and feedback the CQI information based on this assumption. As Figure 20 shown, 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 a (PMI1, RI1) for each CSI-RS resource. As Figure 20 shown, (PMI1, RI1) is fed back based on CRI1, (PMI2, RI2) is fed back based on CRI2, and then a CQI, such as CQI0, is fed back by combining these two (PMI, RI). Further, the terminal needs to assume the transmission schemes of the PDSCH corresponding to the two layers corresponding to these two (PMI, RI). For example, (PMI1, RI1) is fed back for CRI1, and (PMI2, RI2) is fed back for CRI2. For example, when both RI1 and RI2 are 1 (or RI1 = 2, RI2 = 1, and of course other combinations are not excluded), the CQI fed back when different data is transmitted on the RI1 layer and the RI2 layer may be different from the CQI fed back when the same data is transmitted on the RI1 layer and the RI2 layer.
[0713] For example, when the transmission information transmitted by layer RI1 and layer RI2 (where the transmission information is the information bits before channel coding) is the same (or when the intersection of the transmission information included in layer RI1 and layer RI2 is non-empty), feedback CQI1 indicates that a transport block (TB) adopts the modulation order, target code rate, and transport block size indicated by the CQI1, and when the channel coding bit sequences corresponding to one RV version of the TB are respectively included in layer RI1 and layer RI2 and are transmitted on the CSI reference resource, the probability of error of the one TB does not exceed 0.1 (or 0.00001), that is, both layer RI1 and layer RI2 include a redundant version (RV, Redundancy Version) of one TB, as Figure 22 shown. Or it is the repeated transmission of the same RV in layer RI1 and layer RI2, as Figure 21 shown. For example, the RV = 0 of a TB includes 1000 bits after channel coding, and these 1000 bits are transmitted in both layer RI1 and layer RI2.
[0714] When the transmission information transmitted by layer RI1 and layer RI2 is different, feedback CQI2 indicates that a TB adopts the modulation order, target code rate, and transport block size indicated by the CQI2, and when the different channel coding bits corresponding to one RV of a TB in layer RI1 and layer RI2 are transmitted on the CSI reference resource (that is, the intersection of the transmission information included in layer RI1 and layer RI2 is empty), the probability of error of the TB does not exceed 0.1 (or 0.00001), that is, at this time, one RV of a TB is first layer-mapped, then frequency-domain resource-mapped, and then time-domain resource-mapped in layer RI1 and layer RI2. As Figure 23 shown. For example, the RV = 0 of a TB includes 1000 bits after channel coding. These 1000 bits are modulated into 500 modulation symbols. The 250 modulation symbols corresponding to the odd positions of the 500 modulation symbols are transmitted in layer RI1, and the 250 modulation symbols corresponding to the even positions of the 500 modulation symbols are transmitted in layer RI2.
[0715] Furthermore, it is also necessary to make assumptions on whether the RI1 layer and the RI2 layer transmit the same data in a space-division manner (i.e., the intersection of the time-frequency resources occupied by the RI1 layer and the RI2 layer is non-empty and / or the difference set is empty), or in a frequency-division manner (i.e., the difference set of the time-frequency resources occupied by the RI1 layer and the RI2 layer is empty, and the intersection of the frequency-domain resources is empty, that is, at this time, PMI1 and PMI2 correspond to different CSI-RS resources and frequency-domain resources, or at this time, different frequency-domain resources and the corresponding PMI and RI on different frequency-domain resources form a CQI), or in a time-division manner (i.e., the intersection of the time-frequency resources occupied by the RI1 layer and the RI2 layer is empty). Based on the above assumptions, the CQI is obtained and fed back to the base station. Different assumptions may result in different CQIs being fed back. Furthermore, when performing space-division repeated transmission, the CQIs obtained when the channel scrambling sequences corresponding to the RI1 layer and the RI2 layer are the same may also be different.
[0716] The above is to obtain the CQI based on the assumptions of the transmission schemes between different layer groups corresponding to two sets of (PMI, RI). Of course, it does not rule out making assumptions on whether the transmission scheme between different layer groups sent with the same RI based on the same CSI-RS resource is repetition, so as to obtain the corresponding CQI information. Here, one layer corresponds to a column of the precoder matrix indicator (PMI, Precoder Matrix Indicator), and PMI is a matrix of the number of CSI-RS ports * RI layers.
[0717] Similarly, when obtaining the CQI for a CSI-RS resource, assumptions need to be made on the aggregation, that is, the time-domain repeated transmission factor. That is, when the PDSCH is transmitted, different time-domain repetition times may result in different CQIs being fed back. For the same layer group, different time-domain repetition factors result in different CQIs being fed back.
[0718] Similarly, when repeated transmission is performed, different redundancy versions used may result in different CQI information being fed back.
[0719] Similarly, when repeated transmission is performed, the CQI obtained based on the same modulation order corresponding to different repeated transmissions may be different from the CQI obtained based on different modulation orders corresponding to different repeated transmissions. It is necessary to obtain the CQI based on whether the modulation orders corresponding to different repeated transmissions are the same.
[0720] Similarly, when repeated transmission is performed, the CQI obtained based on the same channel coding rate corresponding to different repeated transmissions may be different from the CQI obtained based on different channel coding rates corresponding to different repeated transmissions. It is necessary to obtain the CQI based on whether the channel coding rates corresponding to different repeated transmissions are the same.
[0721] Specifically, for the terminal to obtain the CQI according to the repetition transmission factor and the repetition transmission mode, the terminal side stores the mapping curve from the signal-to-noise ratio (SINR, Signal Interference Ratio) to the block error ratio (BLER, Block Error Ratio) corresponding to each CQI index based on its own reception algorithm for each repetition transmission factor and / or each repetition transmission mode. Under a fixed CQI index, if the repetition transmission factor and / or each repetition transmission mode are different, the mapping curve of SINR to BLER is different. As Figure 24 shown, with the abscissa being the SINR and the ordinate being the BLER, under one CQI, if the repetition transmission factor is different, the mapping curve of SINR to BLER is different. When the terminal obtains a SINR based on the measurement reference signal, it finds the mapping curves of SINR to BLER for each MCS corresponding to the currently assumed repetition transmission factor and / or each repetition transmission mode, and then finds the CQI index with a BLER less than 0.1 (or 0.00001) under the SINR obtained based on the measurement reference signal, and then takes the minimum value among these CQI indexes as the current CQI value.
[0722] See Figure 25 , another embodiment of the present invention proposes a device for sending feedback information, including:
[0723] An acquisition module 2501, configured to acquire channel quality indicator (CQI) information according to at least one of the following information: repetition transmission factor R, repetition transmission mode;
[0724] A CQI information sending module 2502, configured to send the CQI information.
[0725] In the embodiment of the present invention, the repetition transmission mode includes one of the following:
[0726] R layer groups correspond to R spatial domain resources;
[0727] R layer groups correspond to R frequency domain resource groups, and the intersection between different frequency domain resource groups is empty;
[0728] R layer groups correspond to R time domain resource groups, and the intersection between different time domain resource groups is empty;
[0729] Redundancy Version (RV) sequences corresponding to R repeated transmissions;
[0730] Wherein, the repeated transmissions of the same information are included in the data channels corresponding to the R layer groups, and R is a positive integer greater than 1.
[0731] Wherein, the R layer groups or one CQI information correspond to at least one of the following:
[0732] A channel state information-reference signal (CSI-RS) resource;
[0733] A RI information;
[0734] A precoder matrix indicator (PMI) information;
[0735] A set of quasi co-located reference signals; wherein, the set of A quasi co-located reference signals can also be referred to as A TCI states, and a TCI state includes a set of quasi co-located reference signals;
[0736] A column groups of a PMI, where one column of a PMI matrix corresponds to one layer;
[0737] Wherein A is equal to 1, or A is equal to R.
[0738] In an embodiment of the present invention, the repetition transmission factor R satisfies at least one of the following:
[0739] When R is greater than 1, a transmission information is repetitively transmitted on R resources;
[0740] When R is equal to 1, a transmission information is not repetitively transmitted;
[0741] Wherein, the R resources correspond to at least one of the following: time domain resources, spatial domain resources, frequency domain resources, reference signal resources, quasi co-located reference signal sets, RV versions, scrambling sequences, layer groups.
[0742] The embodiment of the present invention obtains the CQI according to the repetition transmission factor and / or the repetition transmission manner, which is closer to the transmission scheme of the actually transmitted PDSCH, so that the fed-back CQI is more accurate, thereby improving the spectrum efficiency and reducing interference. On the other hand, the implementation complexity of the base station is also reduced because the base station does not need to convert the CQI actually used during PDSCH transmission based on the CQI fed back by the terminal, and during this conversion process, due to different implementation algorithms of the base station and the terminal, the conversion may not be accurate.
[0743] Another embodiment of the present invention provides a device for sending feedback information, including a processor and a computer-readable storage medium. Instructions are stored in the computer-readable storage medium, and when the instructions are executed by the processor, the above-mentioned method for sending feedback information is implemented.
[0744] Another embodiment of the present invention provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of any of the above methods for sending feedback information are implemented.
[0745] In the existing NR protocol, when dedicated PUCCH resources are not configured, PUCCH resources are calculated according to control channel elements (CCEs). Since the system information block (SIB) messages notified by each SSB are the same, the CORESET0, search space (SS) 0, and common PUCCH resources corresponding to two TRPs are the same. Especially when there is no ideal backhaul between two TRPs, if the two TRPs independently send PDCCHs on CORESET0, there will be a collision of PUCCH resources for HARQ-ACK of PDSCH scheduled by PDCCHs from different TRPs.
[0746] Another embodiment of the present invention provides an information determination method, including at least one of the following:
[0747] Dividing a synchronization signal block (SSB) corresponding to a physical cell identifier (ID) into E SSB groups; where the value of E is a positive integer;
[0748] Obtaining at least one of the following information according to the SSB group index: hybrid automatic repeat request - acknowledgement (HARQ-ACK) uplink control channel resources, physical random access channel (PRACH) resources, time advance (TA) information.
[0749] In the embodiment of the present invention, obtaining the uplink control channel resources according to the SSB group index of the synchronization signal block (SSB) includes:
[0750] Selecting one of the uplink control channel resources from the uplink control channel resource group corresponding to the SSB group; where different SSB group indexes correspond to different uplink control channel resource groups.
[0751] In the embodiment of the present invention, different SSB group indexes corresponding to different uplink control channel resource groups includes:
[0752] The intersection of the frequency domain resources and / or time domain resources between the uplink control channel resource groups corresponding to different SSB groups is empty.
[0753] The embodiment of the present invention realizes independent scheduling of users based on the SSB group index.
[0754] Embodiment 6
[0755] In this embodiment, the synchronization signal block (SSB) of a physical cell is divided into multiple groups. Further, at least one of the following enhancements can be made:
[0756] Enhancement 1: The SSB group index is introduced in the acquisition of PUCCH resources. In the existing NR protocol, when dedicated PUCCH resources are not configured, the PUCCH resources are calculated based on CCE. Since the system information block (SIB) messages notified by each SSB are the same, the CORESET0, search space (SS) 0, and common PUCCH resources corresponding to two TRPs are the same. Especially when there is no ideal backhaul between two TRPs, if the two TRPs independently send PDCCHs on CORESET0, there will be a collision of PUCCH resources for HARQ-ACK of PDSCH scheduled by PDCCHs from different TRPs. To enable the two TRPs to schedule users relatively independently, the SSB can be divided into multiple groups, and the SSB group index is introduced in the acquisition of PUCCH resources, so that two SSB group indexes correspond to different PUCCH resources. For example, the intersection of the frequency-domain resources and / or time-domain resources between the PUCCH resource groups corresponding to different SSB groups is empty. That is, there are two common PUCCH resource groups, corresponding to two TRPs respectively. As Figure 26 shown, different SSB groups of a physical cell correspond to different PUCCH resources, and the HARQ-ACK of PDSCH scheduled by the PDCCH in CORESET0 / SS0 in different SSB groups selects a PUCCH resource from its respective PUCCH resource group for feedback. Preferably, the SIB messages notified in different SSB groups are the same, and only the time-domain resources and / or frequency-domain resources occupied by different PUCCH resource groups are obtained according to the SSB group index, or the SIB messages notified in different SSB groups can also be different.
[0757] Enhancement 2: The SSB group index is included in the acquisition parameters of the physical random access channel (PRACH) resources, so that different TRPs correspond to different PRACH resource information.
[0758] Enhancement 3: When the terminal selects an SSB, it can select one from each of the two groups of SSBs. When sending the Preamble, it only feeds back that the Preamble is sent on the PRACH resource corresponding to one SSB, and further includes the SSB index selected from the other SSB in msg3.
[0759] Enhancement 4: One group of SSBs corresponds to one TA information, and different SSB groups correspond to different TA information.
[0760] In the above solution, the SSB group index information can be carried by the DMRS sequence information of the PBCH, or the SSB group information can be notified in the PBCH / SIB (System Information Block).
[0761] Another embodiment of the present invention proposes an information determination device, including at least one of the following modules:
[0762] Grouping module, configured to divide the synchronization signal block SSB corresponding to a physical cell identifier ID into E SSB groups; where the value of E is a positive integer;
[0763] Information acquisition module, configured to acquire at least one of the following information according to the SSB group index: the uplink control channel resource where the hybrid automatic repeat request - acknowledgement character HARQ-ACK is located, the physical random access channel PRACH resource, and the time advance TA information.
[0764] In the embodiment of the present invention, the acquiring the uplink control channel resource according to the synchronization signal block SSB group index includes:
[0765] Selecting one of the uplink control channel resources from the uplink control channel resource group corresponding to the SSB group; where different SSB group indexes correspond to different uplink control channel resource groups.
[0766] In the embodiment of the present invention, the different SSB group indexes corresponding to different uplink control channel resource groups includes:
[0767] The intersection of the frequency domain resources and / or time domain resources between the uplink control channel resource groups corresponding to different SSB groups is empty.
[0768] Another embodiment of the present invention proposes an information determination device, including a processor and a computer-readable storage medium, where instructions are stored in the computer-readable storage medium, and when the instructions are executed by the processor, any of the above information determination methods is implemented.
[0769] Another embodiment of the present invention proposes a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of any of the above information determination methods are implemented.
[0770] Another embodiment of the present invention proposes a method for determining a detection opportunity, including:
[0771] Determine the detection opportunity of the downlink control channel scrambled by the cell radio network temporary identifier (C-RNTI) in CORESET0 according to the synchronization signal block (SSB) index corresponding to at least one quasi-co-location reference signal set configured or activated for the control channel resource set CORESET0.

[0773] In this embodiment, more than one quasi-co-location reference signal set is configured or activated for CORESET0, such as more than one transmission configuration indicator (TCI) state, and each TCI state includes a quasi-co-location reference signal set. Determine the detection opportunity of the physical downlink control channel (PDCCH) scrambled by the cell radio network temporary identifier (C-RNTI) in CORESET0 according to the SSB indexes corresponding to the more than one quasi-co-location reference signal set. For example, the detection opportunity of CORESET0 corresponding to SSBi is detection opportunity i, i = 0, 1,... 63. When two SSBs {SSB1, SSB4} are configured or activated for CORESET0, the terminal only detects the PDCCH scrambled by C-RNTI at detection opportunities 1 and 4. When one SSB {SSB52} is configured or activated for CORESET0, the terminal only detects the PDCCH scrambled by C-RNTI at detection opportunity 52.
[0774] Further, the SSB indexes of the CSI-RS / SSB associated with type-D included in the more than one TCI state have a quasi-co-location (QCL) relationship. The quasi-co-location reference signals associated with different quasi-co-location parameters in one TCI state and the same SSB index satisfy the quasi-co-location relationship with respect to the corresponding quasi-co-location parameters.
[0775] Further, the SSB index corresponding to the TCI state / quasi-co-location reference signal set, that is, the SSB index that satisfies the QCL relationship with the quasi-co-location reference signal in the TCI state / quasi-co-location reference signal set.
[0776] By configuring multiple quasi-co-location reference signal sets corresponding to CORESET0 for the terminal, the terminal can detect the control channel on CORESET0 corresponding to more SSBs, improving the resource utilization rate of CORESET0 (for example, the idle CORESET0 can be used for the transmission of dedicated control channels) and improving the performance of the dedicated control channel and / or the common control channel.
[0777] Another embodiment of the present invention provides an apparatus for determining a detection opportunity, including:
[0778] A detection opportunity determination module, configured to determine a detection opportunity of a downlink control channel scrambled by a cell radio network temporary identifier (C-RNTI) in a control channel resource set (CORESET0) according to a synchronization signal block (SSB) index corresponding to at least one quasi co-location reference signal set configured or activated for the CORESET0.
[0779] Another embodiment of the present invention provides an apparatus for determining a detection opportunity, including a processor and a computer-readable storage medium. Instructions are stored in the computer-readable storage medium, and when the instructions are executed by the processor, any of the above methods for determining a detection opportunity is implemented.
[0780] Another embodiment of the present invention provides a computer-readable storage medium, on which a computer program is stored. The computer program is characterized in that when the computer program is executed by a processor, the steps of any of the above methods for determining a detection opportunity are implemented.
[0781] Embodiment 8
[0782] In this embodiment, the entire transmission information included in a transmission block (TB) does not correspond to a cyclic redundancy check (CRC). Instead, the transmission information included in a TB is divided into multiple code blocks (CBs), and each CB has a CRC. Then, after channel coding of each CB, they are concatenated together, modulated, and transmitted. This allows for the situation where during the transmission of an enhanced mobile broadband (eMBB) service, information of an ultra-reliable low-latency communication (URLLC) service arrives. Some code block groups (CBGs) in the eMBB can be replaced by the CBGs of the newly arrived URLLC service. At this time, if all CBGs are transmitted correctly, there is no need for retransmission. If a TB has a CRC not only for each CB but also as a whole, when the CBGs of the newly arrived URLLC service replace some of the eMBB service, the CRC check of the entire TB will fail, and the terminal will feedback a NACK, resulting in the need for retransmission of the entire data.
[0783] Furthermore, it can be determined whether the entire transmission information included in a TB has a CRC through signaling information and / or a predetermined rule.
[0784] Through the above solution, a TB can include URLLC service data and eMBB service data simultaneously. While reducing the DCI load, it can allow the suddenly emerging URLLC service data to be urgently inserted into a CBG of the eMBB service.
[0785] Embodiment 9
[0786] 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. It is determined whether to determine the power difference between the DMRS and the PDSCH according to the CSI-RS information according to the antenna group information and / or the TCI group information.
[0787] Furthermore, if the group information where the CSI-RS and the DMRS / PDSCH are located meets a predetermined condition, the power difference between the DMRS and the PDSCH can be determined according to the number of REs occupied by the CSI-RS in an OFDM symbol. In an OFDM symbol, the more the number of REs occupied by the CSI-RS that meets the condition, the greater the power difference between the DMRS and the PDSCH.
[0788] Furthermore, the DMRS is not included in the time domain symbol where the CSI-RS is located.
[0789] Furthermore, the CSI-RS includes at least one of the following: non-zero power NZP-CSI-RS, zero power ZP-CSI-RS, interference measurement CSI-IM resource;
[0790] Furthermore, the group information is the group information where the reference signal is located in the TCI state corresponding to the CSI-RS and the DMRS / PDSCH, or the transmission antenna group or the reception antenna group corresponding to the CSI-RS and the DMRS / PDSCH.
[0791] The group information where the CSI-RS and the DMRS / PDSCH are located meeting the predetermined condition includes one of the following: the CSI-RS and the DMRS / PDSCH are in the same group, the CSI-RS and the DMRS / PDSCH are in different groups.
[0792] Because when the transmission antennas of the CSI-RS and the DMRS / PDSCH are different, the DMRS / PDSCH cannot be transmitted on the REs occupied by the CSI-RS on the transmission antenna for transmitting the DMRS / PDSCH, and the transmission power on these REs can be used for power enhancement of the DMRS / PDSCH, so that while the transmission power on different time domain symbols is basically equivalent, the reception performance of the DMRS / PDSCH is improved.
[0793] Embodiment 10
[0794] In this embodiment, the terminal reports the maximum number of TCI state groups to which the TCI states activated for the PDSCH under a BWP by the base station through the MAC-CE command belong. For example, different TCI state groups correspond to different TRPs or different receiving antennas of the terminal. Then, the more TCI state groups are activated, the more receiving antennas the terminal needs to activate, and the greater the power consumption of the terminal. The terminal needs to report this capability information to the base station.
