Abstract
Aspects of the present disclosure relate to prioritized random access procedures in wireless systems. An exemplary method generally includes receiving, from a user equipment, a random access request including information identifying a type of a random access event being invoked, identifying one or more parameters associated with a backoff interval to be observed at the user equipment based, at least in part, on a priority associated with the type of the random access event, and transmitting, to the user equipment, a random access response including the identified one or more parameters.
Claims30
A method for wireless communications by a base station, comprising:
- configuring a user equipment with backoff adjustment parameters for one or more priority levels for random access requests;
- receiving, from the user equipment, a random access request;
- and
- transmitting, to the user equipment, a random access response including a base backoff interval to modify a backoff interval at the user equipment based on the priority of the random access request.
A method for wireless communications by a user equipment, comprising:
- receiving, from a base station, configuration information including backoff adjustment parameters for one or more priority levels for random access requests;
- transmitting, to the base station, a random access request;
- receiving, from the base station, a random access response including a base backoff interval;
- and
- based on a backoff adjustment parameter associated with a priority of the random access request and the base backoff interval, determining a backoff interval defining an amount of time to wait until retransmitting the random access request.
An apparatus for wireless communications, comprising:
- a processor configured to:
- configure a user equipment with backoff adjustment parameters for one or more priority levels for random access requests,
- receive, from the user equipment, a random access request, and
- transmit, to the user equipment, a random access response including a base backoff interval to modify a backoff interval at the user equipment based on the priority of the random access request, and
- a memory.
