Abstract
Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a sounding reference signal (SRS) configuration, the SRS configuration including one or more parameters defining an SRS resource, receives a cyclic shift hopping parameter for SRS transmissions, and transmits an SRS on the SRS resource, the SRS configured according to at least the cyclic shift hopping parameter.
Claims26
A user equipment (UE), comprising:
- at least one memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the at least one memory and the at least one transceiver, the at least one processor configured to:
- receive, via the at least one transceiver, a sounding reference signal (SRS) configuration, the SRS configuration including one or more parameters defining an SRS resource;
- receive, via the at least one transceiver, a cyclic shift hopping parameter for SRS transmissions,
- wherein the SRS transmissions are repetitions that span multiple symbols of at least one slot, and
- wherein the cyclic shift hopping parameter indicates that a same cyclic shift is used for the SRS transmissions across the multiple symbols, or that a different cyclic shift is used for different SRS symbols of the multiple symbols;
- and
- transmit, via the at least one transceiver, an SRS on the SRS resource, the SRS configured according to at least the cyclic shift hopping parameter.
