- the terminal will also detect the PDCCH in the CORESET or CORESET group numbered 0, and thus receive the PDSCH0, then the PUCCH resource determined by the terminal for the HARQ-ACK corresponding to the PDSCH0 will come from PUCCH resource set group 0 (this is because the terminal is in The PDCCH corresponding to the PDSCH0 is detected in the CORESET or CORESET group numbered 0, and it is determined based on the principle that the agreed PUCCH resource set group number is the same as the CORESET (group) number).

- the terminal determines the corresponding PUCCH resource set from the determined PUCCH resource set group according to the number of bits of the UCI (including the HARQ-ACK information) to be transmitted.
- the corresponding PUCCH resource is determined from the determined PUCCH resource set according to the PRI value. Since the PUCCH resource set group, timing indication information, and PRI are all sent by the base station to the terminal, the base station can also determine the PUCCH resource used by the terminal in each uplink subslot according to the same process, and the terminal and the base station target the same UL subslot The determined PUCCH resources will be the same, so the base station can receive the information sent by the terminal on the determined PUCCH resources. Each UL subslot may not be grouped.
- the PUCCH resource set group corresponding to the UL subslot of the same feature is determined according to the characteristics of the UL subslot. For example, it is determined that the terminal determines that the UL subslot of the same length corresponds to a same UL subslot according to the length of the UL subslot used. PUCCH resource collection group.
- the terminal determines the PUCCH resource corresponding to the PUCCH resource set corresponding to the PUCCH resource set corresponding to the HARQ-ACK corresponding to the PDSCH transmitted in the TRP according to the number of the CORESET corresponding to the PDCCH corresponding to the PDSCH transmitted by the TRP or the number of the CORESET group.
- Resource collection group For example, it is assumed here that there are two TRPs serving the terminal, and two PUCCH resource collection groups are configured for the terminal, numbered 0 and 1. Two CORESET or CORESET groups are configured for the terminal, numbered 0 and 1.
- TRP0 means that the terminal transmits PDSCH0 through CORESET numbered 0 or CORESET group numbered 0, then the terminal determines that the PUCCH resource of HARQ-ACK corresponding to PDSCH0 will eventually come from PUCCH resource set group 0; TRP1 means that the terminal passes number 1 If the CORESET or CORESET group numbered 1 transmits PDSCH1, the terminal determines that the PUCCH resource of the HARQ-ACK corresponding to PDSCH1 will eventually come from PUCCH resource set group 1.
- the TRP chooses which CORESET or CORESET group to transmit a PDSCH, which is configured or agreed, or not restricted, and is independently selected by the TRP, and when the same TRP transmits different PDSCHs, different CORESET or CORESET groups can be selected.
- the same manner as the processing method of the base station when the aforementioned multiple TRPs are serving the terminal can also be used for corresponding processing.
- the length of the PUCCH resource may be longer in the time domain. After the introduction of UL subslot, the length of a UL subslot is less than the length of UL slot, which may cause The length of the PUCCH resource in the PUCCH resource set group allocated to the UL subslot group exceeds the length of one UL subslot.
- the base station is not expected to instruct the terminal to transmit the first PUCCH resource on the first uplink subslot, or delete the first PUCCH resource that exceeds the first uplink subslot when the terminal transmits the first PUCCH resource on the first uplink subslot
- the symbol of the end symbol include truncation or knockout, which are different processing methods.
- the terminal shall proceed as follows: the terminal does not expect it, the base station indicates one
- the PUCCH resource corresponding to the HARQ-ACK corresponding to the PDSCH is the 4-symbol PUCCH resource, because the end symbol of the PUCCH resource will exceed the end symbol of the UL subslot; or, if the PUCCH resource is indicated to be transmitted in the UL subslot, the Symbols in the PUCCH resource beyond the end symbol of the UL subslot are truncated/broken.
- the terminal does not expect, the base station indicates that the PUCCH resource corresponding to the HARQ-ACK corresponding to a PDSCH is the first PUCCH resource of the 4 symbols, because the end symbol of the first PUCCH resource will exceed The end symbol of the first UL subslot; or the base station and the terminal agree that if the base station indicates a first PUCCH resource, and the first PUCCH resource end symbol exceeds the end symbol of the first UL subslot, then the first PUCCH resource exceeds the first PUCCH resource.
- the symbol of a UL subslot end symbol is truncated or knocked out, and no transmission is performed, and only symbols that do not exceed the first UL subslot end symbol in the first PUCCH resource are used for transmission.
- This method is the simplest way to configure the PUCCH resource set group, and the signaling overhead is the smallest.
- the terminal transmits the third PUCCH resource in the third uplink sub-slot, it is not expected that the base station will instruct the terminal to transmit the third PUCCH resource in the third uplink sub-slot, or delete the third PUCCH resource in the third uplink sub-slot.
- the symbol of the end symbol of the uplink sub-slot group include truncation or knockout, which are different processing methods.
- the UL subslot pattern configured by the base station for the terminal (hereinafter referred to as UE) is "4343" (here, "4343" is used as an example, the principle is the same for other UL subslot patterns), this can be a higher layer
- the signaling configuration, when all the high-level signaling is not updated, the UL subslot pattern in all UL slots is like this.
- the meaning of "4343” is explained as follows: UL subslot included in UL slot are: first UL subslot with 4 symbols, then UL subslot with 3 symbols, then UL subslot with 4 symbols, and then 3 symbols The UL subslot. For other patterns, the principle is the same.
- the rule for the UE to determine a PUCCH resource is: the UE receives the PDCCH that schedules the PDSCH, and obtains the PDSCH to HARQ-ACK timing indication information from the PDCCH (denoted as k1, based on the timing indication information determined by the UL slot/UL subslot, According to the actual configuration, select whether the UL slot or UL subslot represented by k1 at this time is selected.
- k1 represents UL subslot and PUCCH resource indication information (PRI). Determine the position of the UL subslot for future transmission of the PDSCH HARQ-ACK according to k1.
- a group of UL subslots is also called a UL subslot group.
- the number of UL subslot groups may be equal to the number of TRPs configured/served for the UE, for example, currently there are generally two TRPs.
- Each TRP corresponds to a UL subslot group (UL subslot group may include one or more UL subslots).
- the corresponding PUCCH resource set group number is determined according to the number of the CORESET corresponding to the TRP or the number of the CORESET group.
- the PUCCH resource set group number corresponding to the TRP is equal to the number of the CORESET or CORESET group corresponding to the TRP.
- One TRP When multiple TRPs serve the UE, configure one TRP to correspond to one UL subslot group.
- One UL subslot group corresponds to one or more PUCCH resource set groups.
- the time domains of UL subslot groups corresponding to different TRPs do not overlap (Note: the UL subslot group here can also be changed to UL subslot.
- This method is also applicable.
- the simplest one is that one UL subslot contains only one UL subslot, that is, One TRP corresponds to one UL subslot).
- the UE can obtain k1 and PRI from the PDCCH, determine the UL slot/UL subslot to which the HARQ-ACK will be transmitted through k1, and determine the number of bits of UCI to be transmitted (including the HARQ-ACK, and other UCI information)
- the corresponding PUCCH resource set is selected from the determined PUCCH resource set group, and the PUCCH resource to be used is determined from the determined PUCCH resource set according to the PRI.
- the CORESET or CORESET group which establishes a binding relationship with the PUCCH resource collection group, for example, it is always the same number by default.
- the respective HARQ-ACK corresponding to each PDSCH transmitted by the base station for multiple TRPs are in the same UL subslot, then: 1) If these PUCCH resources overlap in time domain, After the HARQ-ACKs corresponding to different PDSCHs are concatenated, they are transmitted in the PUCCH resource indicated by the last PDCCH in the PDCCH corresponding to the PDSCH; or, 2) if the time domains of these PUCCH resources do not overlap, then different PDSCHs correspond to each The HARQ-ACK is transmitted in the respective PUCCH resources.
- the base station When configuring a PUCCH resource set group for the UE, the base station configures a PUCCH resource set group for all UL subslots (including subslots of different lengths). The base station and the UE agree to correspond to a UL subslot of a specific length. If the start symbol index of a PUCCH resource in the PUCCH resource set group exceeds the start symbol index allowed by the UL subslot, the UE or the base station handles it in the following manner: The UE does not expect to be indicated that the PUCCH resource is transmitted on the UL subslot; or the base station is prohibited from instructing the UE to transmit the PUCCH resource on the UL subslot.
