Abstract

A resource determining method, a resource determining apparatus, and a communications device. The resource determining method is applied to a terminal and includes: determining, based on an offset, the number of resources occupied by joint coding of configured grant uplink control information (CG-UCI) and hybrid automatic repeat request acknowledgment (HARQ-ACK) when the HARQ-ACK is multiplexed on a configured grant physical uplink shared channel (CG-PUSCH) for transmission, where the offset is determined by a first offset and/or a second offset, the first offset is an offset corresponding to the HARQ-ACK, and the second offset is an offset corresponding to the CG-UCI.

First claim

What is claimed is:

1 . A resource determining method, applied to a terminal and comprising:
determining, based on an offset β offset PUSCH , the number of resources occupied by joint coding of configured grant uplink control information (CG-UCI) and hybrid automatic repeat request acknowledgment (HARQ-ACK) when the HARQ-ACK is multiplexed on a configured grant physical uplink shared channel (CG-PUSCH) for transmission, wherein the CG-UCI comprises an HARQ identity (ID), a new data indicator (NDI) and/or a redundancy version (RV); the offset β offset PUSCH is determined by a first offset, the first offset is an offset β offset HARQ-ACK of the HARQ-ACK; wherein the offset β offset PUSCH corresponding to joint coding of the CG-UCI and the HARQ-ACK is determined according to the following equation:
β offset PUSCH =β offset HARQ-ACK , wherein

the β offset HARQ-ACK is determined based on a sum of the number of HARQ-ACK bits and the number of CG-UCI bits.

2 . The resource determining method according to claim 1 , wherein
the first offset is configured by radio resource control (RRC) signaling; or the first offset is indicated by downlink control information (DCI).

3 . The resource determining method according to claim 1 , wherein for transmission of the CG-UCI and the HARQ-ACK, the number of coded modulation symbols per layer Q′ ACK+CG-UCI is determined according to the following equation:

wherein
O ACK+CG-UCI is a sum of the number of HARQ-ACK bits and the number of CG-UCI bits, L ACK+CG-UCI is the number of cyclic redundancy check (CRC) bits for the HARQ-ACK and the CG-UCI, β offset PUSCH is the offset corresponding to joint coding of the CG-UCI and the HARQ-ACK, C UL-SCH is the number of code blocks for an uplink shared channel (UL-SCH) of a PUSCH transmission, Kr is the r-th code block size for UL-SCH of the PUSCH transmission, M sc PUSCH is a scheduled bandwidth of the PUSCH transmission, l is an index of an OFDM symbol in the PUSCH transmission, M sc UCI (l) is the number of resource elements that are usable for transmission of UCI in the OFDM symbol l, and l=0, 1, 2, . . . , N symb, all PUSCH −1.
