Abstract
Systems and methods for generating and configuring priority indication parameters associated with positioning measurements and calculations are provided herein. A priority indicator can be signaled to a wireless device and used for determining a priority associated with a positioning reference signal and an overlapping downlink channel transmission. The wireless device selects which overlapping transmission to measure/receive/process and which to drop.
Claims29
A method performed by a wireless device, the method comprising:
- transmitting an indication that the wireless device is configured to measure positioning reference signals (PRSs) without configuration of a measurement gap;
- receiving configuration information including a priority indicator, the priority indicator indicating a priority of reception of at least one channel with respect to reception of PRSs;
- determining a priority associated with a PRS transmission and an overlapping downlink (DL) channel transmission in accordance with the priority indicator;
- and
- responsive to determining that the PRS priority is higher than the DL channel, measuring at least one PRS outside of the measurement gap;
- responsive to determining that the PRS priority is lower than the DL channel, receiving the DL channel transmission.
A wireless device comprising a radio interface and processing circuitry configured to:
- transmit an indication that the wireless device is configured to measure positioning reference signals (PRSs) without configuration of a measurement gap;
- receive configuration information including a priority indicator, the priority indicator indicating a priority of reception of at least one channel with respect to reception of PRSs;
- determine a priority associated with a PRS transmission and an overlapping downlink (DL) channel transmission in accordance with the priority indicator;
- and
- responsive to determining that the PRS priority is higher than the DL channel, measure at least one PRS outside of the measurement gap;
- responsive to determining that the PRS priority is lower than the DL channel, receive the DL channel transmission.
A method performed by a network node, the method comprising:
- obtaining capability information indicating that a wireless device is configured to measure positioning reference signals (PRSs) without configuration of a measurement gap;
- generating configuration information including a priority indicator indicating a priority of reception of at least one channel with respect to reception of PRSs, wherein the priority indicator indicates that the PRS priority is lower than a first type of data on the DL channel, and the PRS priority is higher than a second type of data on the DL channel;
- and
- transmitting, to the wireless device, the configuration information including the priority indicator.
