Abstract
In an aspect, a UE may transmit a first indication that the UE supports a capability to reduce power consumption associated with a constellation and code rate of at least a demodulator of the UE. The UE may receive, based on the first indication, a second indication to utilize a modulation and coding set (MCS) table from a plurality of MCS tables. The UE may receive data from a network node based on the MCS table.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to:
- transmit a first indication that the UE supports a capability to reduce power consumption based on a constellation and a code rate of a demodulator of the UE;
- receive, based on the first indication, a second indication to utilize a first modulation and coding set (MCS) table from a plurality of MCS tables, wherein a second MCS table from the plurality of MCS tables comprises a higher order constellation and a lower code rate than the first MCS table;
- and
- receive data from a network node based on the demodulator and the first MCStable.
An apparatus for wireless communication at a network node, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to:
- receive a first indication that a user equipment (UE) supports a capability to reduce power consumption based on a constellation and a code rate of a demodulator of the UE;
- select, from a plurality of MCS tables, a first MCS table based on the first indication, wherein a second MCS table from the plurality of MCS tables comprises a higher order constellation and a lower code rate than the first MCS table;
- transmit, based on the first indication, a second indication to utilize the selected first MCS table from the plurality of MCS tables;
- and
- transmit data, for the UE, based on a modulator and the first MCS table.
