Abstract
Aspects relate to group-based positioning reference signal (PRS) broadcast in a wireless communication network. Wireless communication devices communicating over a sidelink channel in the wireless communication network may be grouped into one or more positioning groups. Within each positioning group, a respective order of the wireless communication devices in the positioning group may be identified. The wireless communication devices in a positioning group may then communicate PRSs therebetween over the sidelink channel based on the order of wireless communication devices in the positioning group.
Claims30
A first wireless communication device in a wireless communication network, comprising:
- a wireless transceiver;
- a memory;
- and
- a processor communicatively coupled to the wireless transceiver and the memory, wherein the processor and the memory are configured to:
- broadcast a first group formation message over a sidelink channel via the wireless transceiver to form a positioning group comprising a plurality of wireless communication devices including the first wireless communication device;
- and
- communicate positioning reference signals (PRSs) between the plurality of wireless communication devices in the positioning group over the sidelink channel via the wireless transceiver based on an order of the plurality of wireless communication devices in the positioning group.
A method of wireless communication, the method comprising, at a first wireless communication device:
- broadcasting a first group formation message over a sidelink channel to form a positioning group comprising a plurality of wireless communication devices including the first wireless communication device;
- and
- communicating positioning reference signals (PRSs) between the plurality of wireless communication devices in the positioning group over the sidelink channel based on an order of the plurality of wireless communication devices in the positioning group.
A first wireless communication device in a wireless communication network, comprising:
- means for broadcasting a first group formation message over a sidelink channel to form a positioning group comprising a plurality of wireless communication devices including the first wireless communication device;
- and
- means for communicating positioning reference signals (PRSs) between the plurality of wireless communication devices in the positioning group over the sidelink channel based on an order of the plurality of wireless communication devices in the positioning group.
