Abstract

A system and method for providing receiving shared channels during multi TRP transmission are disclosed herein. In one embodiment, an example wireless communication method comprises: determining, by a wireless communication node, a plurality of sets of rate matching configurations. The method further comprises: associating, by the wireless communication node, the plurality of sets of rate matching configurations with respective group identifiers, and transmitting, by the wireless communication node to a wireless communication device, a signal indicating the plurality of sets of rate matching configurations and the group identifiers.

Claims (26)

1. A wireless communication method, comprising:

configuring, by a wireless communication node, a plurality of state fields indicative of a plurality of configured states into two medium access control (MAC) control elements (CEs), each of the two MAC CEs including a respective set of state fields of the plurality of state fields;

associating, by the wireless communication node, the two MAC CEs with respective control resource set (CORESET) group identifiers and with respective cell identifiers of a plurality of configured states corresponding to the set of state fields of a respective MAC CE of the two MAC CEs, wherein each cell identifier of the respective cell identifiers is configured for a corresponding configured state of the plurality of configured states; and

transmitting, by the wireless communication node to a wireless communication device, a MAC CE of the two MAC CEs and a respective CORESET group identifier associated with the MAC CE.

2. The wireless communication method of claim 1 , wherein the plurality of state fields includes at least one of a transmission configuration indication (TCI) state field or a channel state information (CSI) trigger state field.

3. The wireless communication method of claim 1 , wherein associating each MAC CE with a respective CORESET group identifier includes associating the MAC CE with a CORESET group identifier associated with a downlink control information (DCI) that schedules a communication channel configured to carry the MAC CE.

4. A wireless communication method, comprising:

receiving, by a wireless communication device from a wireless communication node, a medium access control (MAC) control element (CE) from two configured MAC CEs, the MAC CE including a set of state fields of a plurality of state fields,

wherein the MAC CE is associated with a respective control resource set (CORESET) group identifier and with a respective cell identifier of a plurality of configured states corresponding to the set of state fields of the MAC CE, wherein the respective cell identifier is configured for a corresponding configured state of the plurality of configured states.

5. The wireless communication method of claim 4 , wherein the plurality of state fields includes at least one of a transmission configuration indication (TCI) state field or a channel state information (CSI) trigger state field.

6. The wireless communication method of claim 4 , wherein for each MAC CEs of the two MAC CEs, the respective CORESET group identifier is a CORESET group identifier associated with a downlink control information (DCI) that schedules a communication channel configured to carry the MAC CEs.

7. A wireless communication apparatus comprising:

at least one processor; and

a memory storing executable instructions, which when executed by the at least one processor, cause the at least one processor to:

configure a plurality of state fields indicative of a plurality of configured states into two medium access control (MAC) control elements (CEs), each of the two MAC CEs including a respective set of state fields of the plurality of state fields;

associate the two MAC CEs with respective control resource set (CORESET) group identifiers and with respective cell identifiers of a plurality of configured states corresponding to the set of state fields of a respective MAC CE of the two MAC CEs, wherein each cell identifier of the respective cell identifiers is configured for a corresponding configured state of the plurality of configured states; and

transmit, via a transmitter, to a wireless communication device, a MAC CE of the two MAC CEs and a respective CORESET group identifier associated with the MAC CE.

8. The wireless communication apparatus of claim 7 , wherein the plurality of state fields includes at least one of a transmission configuration indication (TCI) state field or a channel state information (CSI) trigger state field.

9. The wireless communication apparatus of claim 8 , wherein in associating each MAC CE with a respective CORESET group identifier, the processor is configured to associate the MAC CE with a CORESET group identifier associated with a downlink control information (DCI) that schedules a communication channel configured to carry the MAC CE.

10. A wireless communication apparatus comprising:

at least one processor; and

a memory storing executable instructions, which when executed by the at least one processor, cause the at least one processor to:

receive, via a receiver, from a wireless communication node, a medium access control (MAC) control element (CE) from two configured MAC CEs entities, the MAC CE including a set of state fields of a plurality of state fields,

wherein the MAC CE is associated with a respective control resource set (CORESET) group identifier and with respective cell identifier of a plurality of configured states corresponding to the set of state fields of the MAC CE, wherein the respective a cell identifier is configured for a corresponding configured state of the plurality of configured states.

11. The wireless communication apparatus of claim 10 , wherein the plurality of state fields includes at least one of a transmission configuration indication (TCI) state field or a channel state information (CSI) trigger state field.

12. The wireless communication apparatus of claim 10 , wherein for each MAC CE of the two MAC CEs, the respective CORESET group identifier is a CORESET group identifier associated with a downlink control information (DCI) that schedules a communication channel configured to carry the MAC CE.
