Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first communication having a first frequency offset correction applied. The UE may receive an indication of a frequency offset of the first communication. The UE may transmit a second communication having a second frequency offset correction applied, the second frequency offset correction based at least in part on the first frequency offset correction and the frequency offset of the first communication. Numerous other aspects are described.
Claims29
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- transmit a first uplink communication having a first frequency offset correction applied;
- receive an indication of a frequency offset of the first uplink communication, wherein the indication is based at least in part on an average frequency offset of communications transmitted by the UE during a period of time;
- and
- transmit a second uplink communication having a second frequency offset correction applied, the second frequency offset correction based at least in part on the first frequency offset correction and the frequency offset of the first uplink communication.
A UE for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a downlink communication using a downlink frequency offset correction based at least in part on the downlink communication being a received communication;
- transmit a first uplink communication having a first frequency offset correction applied;
- receive an indication of a frequency offset of the first uplink communication, wherein the indication is based at least in part on an average frequency offset of communications transmitted by the UE during a period of time;
- and
- transmit a second uplink communication using a second frequency offset correction that is different from the downlink frequency offset correction based at least in part on the first frequency offset correction and the frequency offset of the first uplink communication.
A network node for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive, from a user equipment (UE), a first uplink communication having a first frequency offset correction applied;
- transmit an indication of a frequency offset of the first uplink communication, wherein the indication is based at least in part on an average frequency offset of communications transmitted by the UE during a period of time;
- and
- receive a second uplink communication having a second frequency offset correction applied, the second frequency offset correction based at least in part on the first frequency offset correction and the frequency offset of the first uplink communication.
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting a first uplink communication having a first frequency offset correction applied;
- receiving an indication of a frequency offset of the first uplink communication, wherein the indication is based at least in part on an average frequency offset of communications transmitted by the UE during a period of time;
- and
- transmitting a second uplink communication having a second frequency offset correction applied, the second frequency offset correction based at least in part on the first frequency offset correction and the frequency offset of the first uplink communication.
