Abstract
A signal processing method includes receiving, by a terminal, first indication information and second indication information. The first indication information indicates at least one first resource block group. The second indication information indicates a second resource block group. The second resource block group belongs to the at least one first resource block group. The signal processing method also includes receiving, by the terminal, a downlink signal on the at least one first resource block group. The signal processing method further includes processing the downlink signal based on the second indication information.
Claims20
A signal processing method, comprising:
- receiving first indication information and second indication information, wherein the first indication information indicates at least one first resource block group, the second indication information indicates a second resource block group, and the second resource block group belongs to the at least one first resource block group;
- receiving a downlink signal on the at least one first resource block group;
- and
- processing the downlink signal based on the second indication information,
- wherein the processing the downlink signal based on the second indication information comprises:
- determining a third resource block group other than the second resource block group in the at least one first resource block group based on the second indication information;
- demodulating, based on a first demodulation reference signal (DMRS) port associated with the downlink signal and a second DMRS port associated with an interfering signal corresponding to the downlink signal, a downlink signal carried on the third resource block group;
- and
- demodulating, based on the first DMRS port associated with the downlink signal, a downlink signal carried on the second resource block group.

A signal processing method, comprising:
- sending first indication information and second indication information, wherein the first indication information indicates at least one first resource block group, the second indication information indicates a second resource block group, and the second resource block group belongs to the at least one first resource block group;
- and
- sending a downlink signal on the at least one first resource block group,
- wherein the sending the first indication information and the second indication information, comprises:
- sending the first indication information and the second indication information in response to a quantity of first code division multiplexing (CDM) groups being less than a quantity of second CDM groups,
- wherein
- the first CDM group is a CDM group comprising one or more first demodulation reference signal (DMRS) ports, and
- the second CDM group is a CDM group that does not carry data.
5 more elements
A communication apparatus, comprising:
- at least one processor;
- and
- a memory storing programming instructions that, when executed by the at least one processor, cause the communication apparatus to:
- receive first indication information and second indication information, wherein the first indication information indicates at least one first resource block group, the second indication information indicates a second resource block group, and the second resource block group belongs to the at least one first resource block group;
- receive a downlink signal on the at least one first resource block group;
- and
- process the downlink signal based on the second indication information,
- wherein the communication apparatus processes the downlink signal based on the second indication information by:
- determining a third resource block group other than the second resource block group in the at least one first resource block group based on the second indication information;
- demodulating, based on a first demodulation reference signal (DMRS) port associated with the downlink signal and a second DMRS port associated with an interfering signal corresponding to the downlink signal, a downlink signal carried on the third resource block group;
- and
- demodulating, based on the first DMRS port associated with the downlink signal, a downlink signal carried on the second resource block group.
