Description

PUCCH resource indication and determination method, base station, terminal and readable medium

Technical Field

The embodiment of the invention relates to the field of communication, in particular to a PUCCH resource indication and determination method, a base station, a terminal and a readable medium.

Background

A Physical Uplink Control Channel (PUCCH) is one Physical Channel of an Uplink in a New Radio (NR) system, and is used for carrying Uplink Control information. The purpose of setting the PUCCH is: when a User Equipment (UE) is not scheduled, that is, not allocated with Uplink Shared Channel (ul sch) resources, the UE uses the PUCCH to transmit Uplink Control Information (UCI) of Layer1 or Layer 2(Layer1/Layer2, L1/L2), including Channel state reports such as Precoding Matrix Indicator (PMI), Channel Quality Indicator (CQI), etc., Hybrid Automatic Repeat reQuest (HARQ) acknowledgement and scheduling reQuest.

In the current NR system, 5 PUCCH formats are supported, each corresponding to a different UCI size. Different PUCCH resource sets may carry different UCI sizes, e.g., PUCCH resource set i (i ═ 0, …, K-1) may carry UCI sizes in the range of { N ═ N_i，…，N_i+1-1}bit. When there are multiple PUCCH resource sets, N0 ═ 1, N1 ═ 3, N_iThe value of (i-2, …, K-1) is transmitted by the base station to the UE through higher layer signaling.

After a Radio Resource Control (RRC) connection is established, the base station may configure a plurality of PUCCH Resource sets for the UE. The UE determines a usable PUCCH resource according to a size of a UCI to be fed back in a current slot (slot) and indication Information of Downlink Control Information (DCI).

However, before RRC establishment, the UE cannot determine usable PUCCH resources.

Detailed Description

In current NR systems, after RRC connection establishment, the base station may configure multiple PUCCH resource sets for the UE. And the UE determines the usable PUCCH resources according to the size of the UCI to be fed back in the current time slot and the indication information of the DCI. However, before RRC establishment, only the format and length of the PUCCH and related information of the PRB occupied by the PUCCH in the time domain are defined. For example, PUCCH format 0 and format 1 are supported, PUCCH employs a frequency hopping mechanism, where PUCCH format 0 has a length of 2 bits, and a starting symbol is symbol 12 of one slot; PUCCH format 1 may be 4/10/14 symbols in length, with the starting symbols being symbols 10/4/0 within one slot, respectively. There is no clear technical solution for how to indicate specific PUCCH resources for the UE, so the UE cannot determine usable PUCCH resources.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1, an embodiment of the present invention provides a method for indicating PUCCH resources, which may include the following steps:

step S101, determining first information related to PUCCH, wherein the first information related to PUCCH comprises: the method comprises the steps of determining the length of a PUCCH, the format of the PUCCH, the frequency domain boundary corresponding to the PRB occupied by the PUCCH in the first frequency domain hop, and the set information related to the PUCCH.

Step S102, indicating the first information related to the PUCCH through RMSI.

Step S103, generating PUCCH-related second information according to the PUCCH-related first information, wherein the PUCCH-related second information comprises: and x is related information of the initial cyclic shift value, wherein x is an index of a PRB occupied by the first hop of the PUCCH in the frequency domain relative to a boundary of the frequency domain.

Step S104, indicating the second information related to the PUCCH through the PDCCH.

It is understood that step S102 and step S103 only represent different execution actions, and do not represent execution order, and in a specific implementation, step S102 may be executed first, and then step S103 may be executed, that is, the method sequentially includes: step S101, step S102, step S103, step S104; step S103 may be executed first, and then step S102 may be executed, that is, the method sequentially includes: step S101, step S103, step S102, step S104.

In a specific implementation, since various PUCCH formats and lengths are currently defined, it is necessary to indicate the format of the PUCCH and the length of the PUCCH.

In specific implementation, since the PUCCHs with different lengths correspond to unique positions in the time domain, the PRBs occupied by the PUCCHs in the time domain do not need to be considered, and only the related information how to indicate the PRBs occupied by the PUCCHs in the frequency domain needs to be considered. For the PRB occupied by the PUCCH in the frequency domain, first, a frequency domain boundary corresponding to the PRB occupied by the PUCCH in the first frequency domain hop needs to be indicated, and then, based on the indicated frequency domain boundary corresponding to the PRB occupied by the PUCCH in the first frequency domain hop, a value of x is indicated.

In a specific implementation, a frequency domain boundary corresponding to a PRB occupied by the first hop of the PUCCH in the frequency domain may be a highest boundary of an initial uplink Bandwidth Part (BWP), or a lowest boundary of the BWP. That is, x may be counted from the highest boundary of the upstream BWP or from the lowest boundary of the upstream BWP.

Before RRC connection is established, since the UE needs to monitor a broadcast channel to obtain Remaining Minimum System Information (RMSI), format Information of the PUCCH, length Information of the PUCCH, a frequency domain boundary corresponding to a PRB occupied by the PUCCH in a first hop of a frequency domain, and set Information related to the PUCCH may be indicated by the RMSI.

In an embodiment of the present invention, the RMSI corresponds to 4 bits, where 2 bits are used to indicate a format of a PUCCH and a length of the PUCCH, 1 bit is used to indicate a frequency domain boundary corresponding to a PRB occupied by the PUCCH in a first hop in a frequency domain, and 1 bit is used to indicate set information related to the PUCCH.

In a specific implementation, the frequency domain boundary corresponding to the PRB occupied by the 1 bit for indicating the PUCCH in the first frequency domain hop may be: when the index value of the bit (i.e. the corresponding value of the bit) is 0, indicating that the frequency domain boundary corresponding to the PRB occupied by the PUCCH in the first frequency domain hop is the highest boundary of the uplink BWP; and when the index value of the bit is 1, indicating that the frequency domain boundary corresponding to the PRB occupied by the PUCCH in the first frequency domain hop is the lowest boundary of the uplink BWP.

It can be understood that, since the PUCCH employs the frequency hopping mechanism, the frequency domain boundary corresponding to the PRB occupied by the PUCCH in the second frequency domain hop and the frequency domain boundary corresponding to the PRB occupied by the PUCCH in the first frequency domain hop are in a relative mirror relationship. For example, the frequency domain boundary corresponding to the PRB occupied by the PUCCH in the first frequency domain hop is the lowest boundary of the initial uplink BWP, and the frequency domain boundary corresponding to the PRB occupied by the PUCCH in the second frequency domain hop is the highest boundary of the initial uplink BWP. Therefore, the frequency domain boundary corresponding to the PRB occupied by the PUCCH in the second frequency domain hop does not need to be indicated again.

In an embodiment of the present invention, the PUCCH-related set information includes: a set of selectable values for x.

In a specific implementation, the set of selectable values of x may be two, respectively: {0,1}, {2,3}, i.e., the set of selectable values of x may be {0,1}, or {2,3}, and it may be indicated by 1 bit of RMSI which one the set of selectable values of x is specifically used. For example, when 1 bit of the RMSI is 0, {0,1} is selected; when 1 bit of the RMSI is 1, {2,3} is selected.

In embodiment 1, the RMSI corresponds to 4 bits, and the correspondence between the index value of the RMSI and the first information on the PUCCH is shown in table 1.

TABLE 1

It is understood that other mapping tables may be used for the correspondence between the index value of the RMSI bit and the first information related to the PUCCH, and table 1 does not limit the scope of the present invention.

In implementations, since there are multiple values for the selectable set of x, it is desirable to further indicate the particular value of x within the set of selectable values of x.

In an embodiment of the present invention, the Physical Downlink Control Channel (PDCCH) includes: an implicit indication bit based on a CCE-index-based (CCE-index-based), that is, an indication bit implicitly obtained from a starting Control Channel Element (CCE) index of a received PDCCH, indicates a specific value of x within the set of selectable values of x through the implicit indication bit.

In a specific implementation, for the PUCCH, in addition to the related information indicating the PRBs occupied by the PUCCH in the frequency domain, the related information indicating the initial cyclic shift value is also needed, and the UE can normally transmit the PUCCH.
