Abstract

Claims (55)

1 . A signal processing method, comprising:

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.

2 . The signal processing method according to claim 1 , wherein the second resource block group is a resource block group on which no strong interfering signal exists, or a resource block group on which no signal corresponding to a jointly scheduled potential terminal exists.

3 . The signal processing method according to claim 1 , wherein the second resource block group is a resource block group on which a strong interfering signal exists, or a resource block group on which a signal corresponding to a jointly scheduled potential terminal exists.

4 . The signal processing method according to claim 3 , wherein the processing the downlink signal based on the second indication information comprises:

determining, based on the second resource block group indicated by the second indication information, a third demodulation reference signal (DMRS) port associated with an interfering signal corresponding to the downlink signal; and

demodulating, based on a first DMRS port associated with the downlink signal and the third DMRS port, the downlink signal carried on the first resource block group.

5 . 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.

6 . The signal processing method according to claim 5 , wherein the second resource block group is a resource block group on which no strong interfering signal exists, or a resource block group on which no signal corresponding to a jointly scheduled potential terminal exists.

7 . The signal processing method according to claim 5 , wherein the second resource block group is a resource block group on which a strong interfering signal exists, or a resource block group on which a signal corresponding to a jointly scheduled potential terminal exists.

8 . The signal processing method according to claim 5 , wherein the first indication information and the second indication information are sent by using the same downlink control information.

9 . 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.

10 . The communication apparatus according to claim 9 , wherein the second resource block group is a resource block group on which no strong interfering signal exists, or a resource block group on which no signal corresponding to a jointly scheduled potential terminal exists.

11 . The communication apparatus according to claim 9 , wherein the second resource block group is a resource block group on which a strong interfering signal exists, or a resource block group on which a signal corresponding to a jointly scheduled potential terminal exists.

12 . The communication apparatus according to claim 11 , wherein the communication apparatus processes the downlink signal based on the second indication information by:

determining, based on the second resource block group indicated by the second indication information, a third demodulation reference signal (DMRS) port associated with an interfering signal corresponding to the downlink signal; and

demodulating, based on a first DMRS port associated with the downlink signal and the third DMRS port, the downlink signal carried on the first resource block group.

13 . A communication apparatus, comprising:
