Abstract
Disclosed are techniques for sensing. In an aspect, a wireless node receives or determines a time-division duplex (TDD) configuration that configures a set of contiguous downlink symbols, a set of contiguous uplink symbols and a set of contiguous cell-specific flexible symbols that follows the set of contiguous downlink symbols and precedes the set of contiguous uplink symbols. The wireless node further performs a radio frequency for sensing (RF-S) operation during one or more flexible symbols of the set of contiguous cell-specific flexible symbols.
Claims30
A method of operating a wireless node, comprising:
- receiving or determining a time-division duplex (TDD) configuration that configures a set of contiguous downlink symbols, a set of contiguous uplink symbols and a set of contiguous cell-specific flexible symbols that follows the set of contiguous downlink symbols and precedes the set of contiguous uplink symbols;
- and
- performing a radio frequency for sensing (RF-S) operation during one or more flexible symbols of the set of contiguous cell-specific flexible symbols,
- wherein the RF-S operation comprises a wireless network component-centric RF-S operation, the wireless node corresponds to a wireless network component that serves at least one user equipment (UE), and a request is received from a sensing server to configure the one or more flexible symbols for the RF-S operation, or
- wherein the RF-S operation comprises a UE-centric RF-S operation and a transmission power associated with the RF-S operation is lower than a predetermined or configured maximum transmission power threshold.

- and
- perform a radio frequency for sensing (RF-S) operation during one or more flexible symbols of the set of contiguous cell-specific flexible symbols,
- wherein the RF-S operation comprises a wireless network component-centric RF-S operation, the wireless node corresponds to a wireless network component that serves at least one user equipment (UE), and a request is received from a sensing server to configure the one or more flexible symbols for the RF-S operation, or
- wherein the RF-S operation comprises a UE-centric RF-S operation and a transmission power associated with the RF-S operation is lower than a predetermined or configured maximum transmission power threshold.
