Abstract
Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE), may identify a default modulation and coding scheme table and a preconfigured modulation and coding scheme table associated with a resource pool. The UE may receive, from a transmitting communication device, an indication of the preconfigured modulation and coding scheme table to use for upcoming sidelink communications. The UE may then communicate based on the preconfigured modulation and coding scheme table.
Claims30
A method for wireless communication at a receiving user equipment, comprising:
- identifying a default modulation and coding scheme table associated with a resource pool and a preconfigured modulation and coding scheme table associated with the resource pool, wherein the preconfigured modulation and coding scheme table overrides the default modulation and coding scheme table;
- receiving, from a transmitting user equipment and prior to selecting either of the default modulation and coding scheme table or the preconfigured modulation and coding scheme table that overrides the default modulation and coding scheme table, an indication of the preconfigured modulation and coding scheme table to use for upcoming sidelink communications;
- selecting the preconfigured modulation and coding scheme table instead of the default modulation and coding scheme table based at least in part on the preconfigured modulation and coding scheme table overriding the default modulation and coding scheme table in accordance with the received indication;
- and
- receiving data from the transmitting user equipment using the preconfigured modulation and coding scheme table.
A method for wireless communication at a transmitting user equipment, comprising:
- identifying a default modulation and coding scheme table and a preconfigured modulation and coding scheme table associated with a resource pool, wherein the preconfigured modulation and coding scheme table overrides the default modulation and coding scheme table;
- transmitting, to a receiving user equipment and prior to the receiving user equipment selecting either of the default modulation and coding scheme table or the preconfigured modulation and coding scheme table that overrides the default modulation and coding scheme table, an indication of the preconfigured modulation and coding scheme table to use for upcoming sidelink communications;
- and
- transmitting data to the receiving user equipment using the preconfigured modulation and coding scheme table.
An apparatus for wireless communication at a receiving user equipment, comprising:
- a processor,
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- identify a default modulation and coding scheme table associated with a resource pool and a preconfigured modulation and coding scheme table associated with the resource pool, wherein the preconfigured modulation and coding scheme table overrides the default modulation and coding scheme table;
- receive, from a transmitting user equipment and prior to selecting either of the default modulation and coding scheme table or the preconfigured modulation and coding scheme table that overrides the default modulation and coding scheme table, an indication of the preconfigured modulation and coding scheme table to use for upcoming sidelink communications;
- select the preconfigured modulation and coding scheme table instead of the default modulation and coding scheme table based at least in part on the preconfigured modulation and coding scheme table overriding the default modulation and coding scheme table in accordance with the received indication;
- and
- receive data from the transmitting user equipment using the preconfigured modulation and coding scheme table.
