Repeat transmission method and apparatus, chip and computer program

A method for indicating transmission repetition, comprising:

• acquiring, by a terminal device, in case of a time domain resource assignment indication field of downlink control information being reused to indicate repetition information, the repetition information from a repetition field in Physical Downlink Shared Channel-time domain resource allocation (PDSCH-TimeDomainResourceAllocation) and/or Physical Uplink Shared Channel-time domain resource allocation (PUSCH-TimeDomainResourceAllocation);
• wherein the repetition information comprises information about a number of repetitions that indicates the terminal device to perform transmission;
• wherein the repetition field is added to the PDSCH-TimeDomainResourceAllocation and/or PUSCH-TimeDomainResourceAllocation for indicating the repetition information;
• and performing, by the terminal device, transmission according to the repetition information;
• wherein PDSCH-TimeDomainResourceAllocation is an element of PUSCH-TimeDomainResourceAllocationList, which is an information element (IE) of PUSCH-Config. and PUSCH-TimeDomainResourceAllocation is an element of PDSCH-TimeDomainResourceAllocationList, which is an IE of PUSCH-Config.

An apparatus for indicating transmission repetition, comprising a processor and a transceiver;

• wherein the transceiver is configured to reuse a time domain resource assignment indication field of downlink control information to indicate repetition information to a terminal device by transmitting the repetition information to the terminal device through a repetition field in Physical Downlink Shared Channel-time domain resource allocation (PDSCH-TimeDomainResourceAllocation) and/or Physical Uplink Shared Channel-time domain resource allocation (PUSCH-TimeDomainResourceAllocation);
• wherein the repetition field is added to the PDSCH-TimeDomainResourceAllocation and/or PUSCH-TimeDomainResourceAllocation for indicating the repetition information;
• wherein the repetition information comprises information about a number of repetitions that indicates the terminal device to perform transmission;
• wherein PDSCH-TimeDomainResourceAllocation is an element of PUSCH-TimeDomainResourceAllocationList, which is an information element (IE) of PUSCH-Config. and PUSCH-TimeDomainResourceAllocation is an element of PDSCH-TimeDomainResourceAllocationList, which is an IE of PUSCH-Config.
