Abstract
Certain aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for using information related to a sidelink to optimize operation on a cellular link. According to certain aspects, using a vehicle to everything (V2X) ID of a UE (or a device associated with the UE, such as a vehicle), a base station (e.g., a gNB) may obtain information about the UE from a roadside unit (RSU). The base station may use this information (e.g., UE location, speed, or path information) to help optimize cellular communications with the UE.
Claims26
A method for wireless communications by a user equipment (UE), comprising:
- providing, to a network entity via a second link, an indication of a first identifier (ID) of the UE used for sidelink communications with a wireless node on a first link, wherein the sidelink communications convey at least one of:
- position information, speed information, path information, or a combination thereof, of the UE to the wireless node;
- receiving information from the network entity;
- adjusting one or more parameters based on the information, wherein the one or more parameters comprise one or more parameters related to beams used for communication between the UE and the network entity;
- and
- communicating with the network entity via the second link based on the one or more adjusted parameters.
A method for wireless communications by a wireless node, comprising:
- receiving one or more sidelink messages from a user equipment (UE) via a first link using a first identifier (ID) for the UE, wherein the one or more sidelink messages convey at least one of:
- position information, speed information, path information, or a combination thereof, for the UE;
- receiving, via a second link, a request from a network entity for information associated with at least the first ID;
- and
- transmitting, via the second link, a message to the network entity including the requested information associated with the first ID, wherein the requested information comprises at least one of:
- the position information, the speed information, the path information, or a combination thereof.
A method for wireless communications by a network entity, comprising:
- obtaining, from a user equipment (UE), a message indicating a first identifier (ID) for a sidelink communication;
- outputting a request, including the first ID, to a wireless node for information associated with at least one of the first ID;
- obtaining, from the wireless node, a message including the requested information associated with the first ID, wherein the requested information comprises at least one of:
- position information, speed information, path information, or a combination thereof, for the UE;
- and
- adjusting one or more parameters for communications between the UE and the network entity based on the requested information, wherein the one or more parameters comprise one or more parameters related to beams used for communication between the UE and network entity.
