Abstract
This application discloses a method for indicating PDSCH receiving information, a data receiving method, and an apparatus. According to this application, a network device generates first indication information, where the first indication information is used to indicate physical downlink shared channel PDSCH receiving information, and the PDSCH receiving information includes information identical to physical downlink control channel PDCCH receiving information; and the network device transmits the first indication information over a PDCCH. This application can be used to improve efficiency of indicating PDSCH receiving information, thereby improving PDSCH receiving performance.
Claims13
A method, comprising:
- receiving, by a terminal, first indication information transmitted by a network device over a first physical downlink control channel (PDCCH), wherein the first indication information indicates a piece of physical downlink shared channel (PDSCH) receiving information, and the piece of PDSCH receiving information is identical to a piece of N pieces of PDCCH receiving information configured for the terminal, and N is an integer greater than 1;
- receiving, by the terminal, second indication information transmitted by the network device over a second PDCCH, wherein the second indication information indicates the piece of PDSCH receiving information that is identical to the piece of PDCCH receiving information, and the first PDCCH is the same PDCCH or a different PDCCH than the second PDCCH;
- and
- receiving, by the terminal, based on the piece of PDSCH receiving information, data transmitted over a PDSCH.
An apparatus, comprising:
- at least one processor;
- and a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct to:
- generate first indication information, wherein the first indication information indicates a piece of physical downlink shared channel (PDSCH) receiving information, and the piece of PDSCH receiving information is identical to a piece of N pieces of physical downlink control channel (PDCCH) receiving information configured for a terminal, and N is an integer greater than 1;
- generate second indication information, wherein the second indication information indicates the piece of PDSCH receiving information that is identical to the piece of PDCCH receiving information;
- and
- cause a transceiver to transmit the first indication information over a first PDCCH and the second indication information over a second PDCCH, wherein the first PDCCH is the same PDCCH or a different PDCCH than the second PDCCH.
An apparatus, comprising:
- at least one processor;
- and a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct to:
- cause a transceiver to receive first indication information transmitted by a network device over a first physical downlink control channel (PDCCH), wherein the first indication information indicates physical downlink shared channel (PDSCH) receiving information, and the PDSCH receiving information is identical to PDCCH receiving information, wherein the first indication information comprises information indicating that the PDSCH receiving information is associated with the PDCCH receiving information, and wherein the PDSCH receiving information being associated with the PDCCH receiving information comprises:
- a quasi co-location (QCL) assumption relation existing between a PDSCH and a third PDCCH, wherein the first PDCCH and the third PDCCH are a same PDCCH or are different PDCCHs;
- and
- cause the transceiver to receive, based on the PDSCH receiving information indicated by the first indication information, data transmitted over the PDSCH.
