Abstract
Disclosed are techniques for wireless signaling. In an aspect, a user equipment (UE) transmits, to a network component, an indication of a capability to estimate a carrier frequency offset (CFO) of the UE associated with radio frequency for sensing (RF-S) operations. In another aspect, the network component estimates the CFO of the UE (e.g., based on measurement information from the UE and/or wireless node(s)). In some designs, the network component further transmits, to the UE, the CFO of the UE (e.g., for CFO compensation associated with RF-S sensing operation(s)).
Claims48
A method of operating a user equipment (UE), comprising:
- determining that the UE is capable of estimating a carrier frequency offset (CFO) of the UE;
- transmitting an indication of the UE capability to estimate the CFO to a network component;
- and
- reporting radio frequency for sensing (RF-S) measurement information associated with a RF-S operation (i) that is compensated for the CFO of the UE or (ii) that is not compensated for the CFO of the UE along with an indication of the CFO of the UE.
A method of operating a network component, comprising:
- receiving, from a user equipment (UE), an indication of a user equipment (UE) capability to estimate a carrier frequency offset (CFO) of the UE;
- and
- performing one or more actions related to an RF-S operation based on the UE capability;
- and
- receiving, from the UE, radio frequency for sensing (RF-S) measurement information associated with the RF-S operation (i) that is compensated for the CFO of the UE or (ii) that is not compensated for the CFO of the UE along with an indication of the CFO of the UE.
A method of operating a network component, comprising:
- transmitting reference signal (RS) configuration information to a user equipment (UE) and one or more wireless nodes that configures a transmission of one or more RSs from the UE to the one or more wireless nodes;
- receiving measurement information associated with the one or more RSs from the one or more wireless nodes;
- and
- estimating a carrier frequency offset (CFO) of the UE based on the measurement information;
- and
- transmitting, to the UE, an indication of the CFO of the UE.
A user equipment (UE), comprising:
- one or more memories;
- one or more transceivers;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- determine that the UE is capable of estimating a carrier frequency offset (CFO) of the UE;
- transmit, via the one or more transceivers, an indication of the UE capability to estimate the CFO to a network component;
- and
- report radio frequency for sensing (RF-S) measurement information associated with a RF-S operation (i) that is compensated for the CFO of the UE or (ii) that is not compensated for the CFO of the UE along with an indication of the CFO of the UE.
A network component, comprising:
- one or more memories;
- one or more transceivers;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- receive, via the one or more transceivers, from a user equipment (UE), an indication of a user equipment (UE) capability to estimate a carrier frequency offset (CFO) of the UE;
- and
- perform one or more actions related to an RF-S operation based on the UE capability;
- and
- receive, from the UE, radio frequency for sensing (RF-S) measurement information associated with the RF-S operation (i) that is compensated for the CFO of the UE or (ii) that is not compensated for the CFO of the UE along with an indication of the CFO of the UE.
A network component, comprising:
- one or more memories;
- one or more transceivers;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- transmit, via the one or more transceivers, reference signal (RS) configuration information to a user equipment (UE) and one or more wireless nodes that configures a transmission of one or more RSs from the UE to the one or more wireless nodes;
- receive, via the one or more transceivers, measurement information associated with the one or more RSs from the one or more wireless nodes;
- and
- estimate a carrier frequency offset (CFO) of the UE based on the measurement information;
- and
- transmit, via the one or more transceivers, to the UE, an indication of the CFO of the UE.
