Abstract
A base station configures, for a terminal, a contention-free random access resource for a beam failure recovery request. After determining that a beam failure has occurred, the terminal performs random access, and retains the contention-free random access resource after the random access succeeds, so that a beam failure recovery latency and signaling overheads can be reduced.
Claims20
A communication method, comprising:
- receiving, by an apparatus, configuration information, wherein the configuration information comprises information indicating one or more contention-free random access resources, and wherein the one or more contention-free random access resources comprise a contention-free random access resource for a beam failure recovery request;
- sending, by the apparatus, a random access request based on the configuration information;
- and
- upon random access being completed, retaining, by the apparatus, the contention-free random access resource for a beam failure recovery request.
A communications apparatus, comprising:
- a transceiver, configured to:
- receive configuration information, wherein the configuration information comprises information indicating one or more contention-free random access resources, and wherein the one or more contention-free random access resources comprise a contention-free random access resource for a beam failure recovery request;
- and
- send a random access request based on the configuration information;
- and
- a processor, configured to:
- upon random access being completed, retain the contention-free random access resource for a beam failure recovery request.
A non-transitory computer-readable storage medium having processor-executable instructions stored thereon, wherein the instructions, when executed, facilitate:
- receiving, by an apparatus, configuration information, wherein the configuration information comprises information indicating one or more contention-free random access resources, and wherein the one or more contention-free random access resources comprise a contention-free random access resource for a beam failure recovery request;
- sending, by the apparatus, a random access request based on the configuration information;
- and
- upon random access being completed, retaining, by the apparatus, the contention-free random access resource for a beam failure recovery request.
