Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a block error rate (BLER) target for communications associated with the user equipment; determine a resource allocation pattern for transmission of channel state information reference signals (CSI-RS) based at least in part on the BLER target; and monitor one or more resources, indicated by the resource allocation pattern, for the CSI-RS. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- determining, by the UE, a block error rate (BLER) target for communications associated with the UE;
- determining, by the UE, a resource allocation pattern for transmission of channel state information reference signals (CSI-RS) based at least in part on the BLER target, wherein the resource allocation pattern indicates a number of the CSI-RS to be transmitted;
- and
- monitoring, by the UE, one or more resources, indicated by the resource allocation pattern, for the CSI-RS.
A method of wireless communication performed by a user equipment (UE), comprising:
- determining, by the UE, a block error rate (BLER) target for communications associated with the UE;
- determining, by the UE, a resource allocation pattern for transmission of channel state information reference signals (CSI-RS) based at least in part on the BLER target, wherein the resource allocation pattern indicates a number of the CSI-RS to be transmitted;
- determining, by the UE, at least one of a number of bits to be used to indicate a channel quality indicator (CQI) index or a reporting timeline associated with reporting the CQI index based at least in part on the BLER target;
- and
- transmitting, by the UE, the CQI index using at least one of the number of bits or the reporting timeline.
A user equipment (UE) for wireless communication, comprising:
- memory;
- a transmitter;
- and
- one or more processors coupled to the memory, the memory and the one or more processors configured to:
- determine, by the UE, a block error rate (BLER) target for communications associated with the UE;
- determine, by the UE, a resource allocation pattern for transmission of channel state information reference signals (CSI-RS) based at least in part on the BLER target, wherein the resource allocation pattern indicates a number of the CSI-RS to be transmitted;
- and
- monitor, by the UE, one or more resources, indicated by the resource allocation pattern, for the CSI-RS.
A user equipment (UE) for wireless communication, comprising:
- memory;
- and
- one or more processors coupled to the memory, the memory and the one or more processors configured to:

- determine, by the UE, a resource allocation pattern for transmission of channel state information reference signals (CSI-RS) based at least in part on the BLER target, wherein the resource allocation pattern indicates a number of the CSI-RS to be transmitted;
- determine, by the UE, at least one of a number of bits to be used to indicate a channel quality indicator (CQI) index or a reporting timeline associated with reporting the CQI index based at least in part on the BLER target;
- and
- transmit, by the UE, the CQI index using at least one of the number of bits or the reporting timeline.
