Abstract
Aspects relate to sidelink positioning using second stage sidelink control information (SCI-2). A first wireless communication device (e.g., first UE) may transmit SCI-2 including a sidelink positioning establishment message to establish a sidelink positioning session with at least a second wireless communication device (e.g., a second UE). Each of the first UE and second UE may then transmit positioning reference signals (PRSs) and generate and transmit sidelink positioning information based on the PRSs during the sidelink positioning session. The sidelink positioning information may further be transmitted via SCI-2.
Claims30
A first wireless communication device in a wireless communication network, comprising:
- a transceiver,
- a memory;
- and
- a processor coupled to the transceiver and the memory, wherein the processor and the memory are configured to:
- transmit second stage sidelink control information (SCI-2) comprising a sidelink positioning session establishment message via the transceiver to establish a sidelink positioning session with at least a second wireless communication device;
- communicate one or more sidelink positioning reference signals with at least the second wireless communication device during the sidelink positioning session via the transceiver, and
- receive sidelink positioning information based on the one or more sidelink positioning reference signals from at least the second wireless communication device via the transceiver.
A method for sidelink positioning at a first wireless communication device in a wireless communication network, the method comprising:
- transmitting second stage sidelink control information (SCI-2) comprising a sidelink positioning session establishment message to establish a sidelink positioning session with at least a second wireless communication device;
- communicating one or more sidelink positioning reference signals with at least the second wireless communication device during the sidelink positioning session;
- and
- receiving sidelink positioning information based on the one or more sidelink positioning reference signals from at least the second wireless communication device.
