Abstract
Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) configured to operate in discontinuous reception (DRX) mode switches to DRX active time of a DRX cycle of the DRX mode, and transmits one or more uplink positioning reference signal (UL-PRS) resources of an UL-PRS occasion based on the UL-PRS occasion at least partially overlapping DRX OFF time of the DRX cycle after the DRX active time.

A method of wireless communication performed by a user equipment (UE) configured to operate in discontinuous reception (DRX) mode, comprising:
- switching to DRX active time of a DRX cycle of the DRX mode;
- and
- transmitting one or more uplink positioning reference signal (UL-PRS) resources of an UL-PRS occasion based on the UL-PRS occasion at least partially overlapping DRX OFF time of the DRX cycle after the DRX active time,
- wherein transmitting the one or more UL-PRS resources of the UL-PRS occasion comprises transmitting a subset of UL-PRS resources of the UL-PRS occasion based on the UL-PRS occasion partially overlapping the DRX active time and the DRX OFF time.
A method of wireless communication performed by a user equipment (UE) configured to operate in discontinuous reception (DRX) mode, comprising:
- switching to DRX active time of a DRX cycle of the DRX mode;
- and
- transmitting one or more uplink positioning reference signal (UL-PRS) resources of an UL-PRS occasion based on the UL-PRS occasion at least partially overlapping DRX OFF time of the DRX cycle after the DRX active time;
- and
- receiving a wakeup signal (WUS) indicating whether the UE is expected to monitor a physical downlink control channel (PDCCH) during a next DRX cycle or to skip the next DRX cycle,
- wherein, based on the WUS indicating that the UE is expected to monitor the PDCCH during the next DRX cycle:
- transmitting the one or more UL-PRS resources of the UL-PRS occasion comprises transmitting all UL-PRS resources of the UL-PRS occasion based on the UL-PRS occasion partially overlapping the DRX active time and the DRX OFF time or fully overlapping the DRX OFF time, or
- transmitting the one or more UL-PRS resources of the UL-PRS occasion comprises transmitting a subset of UL-PRS resources of the UL-PRS occasion based on the UL-PRS occasion partially overlapping the DRX active time and the DRX OFF time.
A user equipment (UE) configured to operate in discontinuous reception (DRX) mode, comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- switch to DRX active time of a DRX cycle of the DRX mode;
- and
- transmit, via the at least one transceiver, one or more uplink positioning reference signal (UL-PRS) resources of an UL-PRS occasion based on the UL-PRS occasion at least partially overlapping DRX OFF time of the DRX cycle after the DRX active timer,
- wherein the at least one processor configured to transmit the one or more UL-PRS resources of the UL-PRS occasion comprises the at least one processor configured to transmit a subset of UL-PRS resources of the UL-PRS occasion based on the UL-PRS occasion partially overlapping the DRX active time and the DRX OFF time.
A user equipment (UE) configured to operate in discontinuous reception (DRX) mode, comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- switch to DRX active time of a DRX cycle of the DRX mode;
- and
- transmit, via the at least one transceiver, one or more uplink positioning reference signal (UL-PRS) resources of an UL-PRS occasion based on the UL-PRS occasion at least partially overlapping DRX OFF time of the DRX cycle after the DRX active time;
- and
- receive, via the at least one transceiver, a wakeup signal (WUS) indicating whether the UE is expected to monitor a physical downlink control channel (PDCCH) during a next DRX cycle or to skip the next DRX cycle,
- wherein, based on the WUS indicating that the UE is expected to monitor the PDCCH during the next DRX cycle:
- the at least one processor configured to transmit, via the at least one transceiver, the one or more UL-PRS resources of the UL-PRS occasion comprises the at least one processor configured to transmit, via the at least one transceiver, all UL-PRS resources of the UL-PRS occasion based on the UL-PRS occasion partially overlapping the DRX active time and the DRX OFF time or fully overlapping the DRX OFF time, or
- the at least one processor configured to transmit, via the at least one transceiver, the one or more UL-PRS resources of the UL-PRS occasion comprises the at least one processor configured to transmit, via the at least one transceiver, a subset of UL-PRS resources of the UL-PRS occasion based on the UL-PRS occasion partially overlapping the DRX active time and the DRX OFF time.
A user equipment (UE) configured to operate in discontinuous reception (DRX) mode, comprising:
- means for switching to DRX active time of a DRX cycle of the DRX mode;
- and
- means for transmitting one or more uplink positioning reference signal (UL-PRS) resources of an UL-PRS occasion based on the UL-PRS occasion at least partially overlapping DRX OFF time of the DRX cycle after the DRX active time,
- wherein the means for transmitting the one or more UL-PRS resources of the UL-PRS occasion comprises means for transmitting a subset of UL-PRS resources of the UL-PRS occasion based on the UL-PRS occasion partially overlapping the DRX active time and the DRX OFF time.
A non-transitory computer-readable medium storing computer-executable instructions that, when executed by a user equipment (UE) configured to operate in discontinuous reception (DRX) mode, cause the UE to:
- switch to DRX active time of a DRX cycle of the DRX mode;
- and
- transmit one or more uplink positioning reference signal (UL-PRS) resources of an UL-PRS occasion based on the UL-PRS occasion at least partially overlapping DRX OFF time of the DRX cycle after the DRX active time,
- wherein, to transmit the one or more UL-PRS resources of the UL-PRS occasion, the computer-executable instructions, when executed by the UE, cause the UE to transmit a subset of UL-PRS resources of the UL-PRS occasion based on the UL-PRS occasion partially overlapping the DRX active time and the DRX OFF time.
