Abstract
When configured, a channel state information reference signal (CSI-RS) can be used to identify new beams. If CSI-RS based monitoring fails to identify new beams, and no other reference signals (RS) are used for beam management, the user equipment cannot identify a new beam. However, instead of using a 4-step random access channel (RACH) procedure for beam recovery request transmission, a modified 2-step contention-based RACH procedure can saves overhead and reduce latency associated with the 4-step procedure.
Claims20
A method, comprising:
- in response to a determination of a first failure of a reference signal configured to manage a first beam, the first failure indicating that the reference signal was not received, determining, by a mobile device that is part of a wireless network and that comprises a processor, a second failure associated with the first beam, wherein the reference signal and the first beam are to be received by the mobile device from a network device of the wireless network;
- in response to a condition associated with the reference signal being determined to have been satisfied, identifying, by the mobile device, a second beam that is not the first beam;
- and
- facilitating, by the mobile device, a transmission of the second beam via a transmission channel for a recovery request related to a recovery associated with the first beam to mitigate the second failure.
A mobile device, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- in response to a first determination of a first failure associated with a reference signal configured to manage a first beam, determining a second failure associated with the first beam, wherein the reference signal and the first beam have been directed to the mobile device from a network device of a wireless network;
- in response to a condition associated with the reference signal being determined to have been satisfied, identifying a second beam that is not the first beam, wherein the condition is further associated with a second determination that the reference signal does not identify the second beam;
- in response to the second determination that the reference signal does not identify the second beam, utilizing a synchronization signal block associated with a synchronization signal to identify the second beam;
- and
- transmitting the second beam via a random access channel for a recovery request related to a recovery of the first beam to rectify the second failure.
A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- in response to a first determination of a first failure associated with a blocked reference signal of a wireless network, facilitating determining a second failure associated with a first beam associated with the blocked reference signal;
- in response to a condition associated with the blocked reference signal being determined to have been satisfied, facilitating identifying a second beam, wherein the condition is further associated with a second determination that the blocked reference signal does not identify the second beam;
- in response to the second determination that the blocked reference signal does not identify the second beam, facilitating utilizing a synchronization signal block associated with a synchronization signal to identify the second beam;
- and
- facilitating transmitting data associated with the second beam via a random access channel for a recovery request related to a recovery of the first beam to rectify the second failure.
