US 11,638,176 B2 · Techniques for controlling admission for sidelink communications

Abstract

Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

Claims20

Dependent claims

A method for wireless communication, comprising:

receiving an indication that a first data flow is to be initiated in a device-to-device sidelink connection between a first UE and at least a second UE;
identifying a quality of service associated with the first data flow;
determining that a first link between the first UE and at least the second UE can support the first data flow based at least in part on the quality of service associated with the first data flow, available resources associated with the first link, a channel quality of the first link, and an available throughput of the first link, wherein the available throughput of the first link is based at least in part on time-division multiplexing the first link with one or more other links between the first UE and one or more of a network entity or one or more other UEs;
and
establishing the first data flow with at least the second UE based at least in part on the determination.

2 more elements

An apparatus for wireless communication, comprising:

a processor,
memory coupled with the processor;
and
instructions stored in the memory and executable by the processor to cause the apparatus to:
receive an indication that a first data flow is to be initiated in a device-to-device sidelink connection between a first UE and at least a second UE;
identify a quality of service associated with the first data flow;
determine that a first link between the first UE and at least the second UE can support the first data flow based at least in part on the quality of service associated with the first data flow, available resources associated with the first link, a channel quality of the first link, and an available throughput of the first link, wherein the available throughput of the first link is based at least in part on time-division multiplexing the first link with one or more other links between the first UE and one or more of a network entity or one or more other UEs;
and
establish the first data flow with at least the second UE based at least in part on the determination.
