Abstract
A base station (BS)/user equipment (UE) for performing radio frequency beam management and recovery in communication with a UE/BS. The BS/UE includes a processor and a memory that stores first and second thresholds. The processor evaluates a beam quality metric against the first and second thresholds, performs beam switching and/or beam broadening in response to determining the beam quality metric falls below the first threshold, and performs a beam failure recovery procedure in response to determining the beam quality metric falls below the second threshold.
Claims19
A method for performing radio frequency beam management and recovery in communication between a base station (BS) and a user equipment (UE), the method comprising:
- configuring first and second thresholds;
- wherein the second threshold indicates a lower beam quality than the first threshold;
- configuring first and second periods respectively associated with the first and second thresholds;
- evaluating a beam quality metric of a current beam against the first and second thresholds and the associated first and second periods;
- performing beam switching and/or beam broadening in response to determining the beam quality metric of the current beam falls below the first threshold for at least the first period;
- performing a beam failure recovery procedure in response to determining the beam quality metric of the current beam falls below the second threshold for at least the second period;
- and
- wherein said evaluating a beam quality metric of the current beam against the first and second thresholds and the first and second periods is performed in parallel such that when the beam quality falls below the second threshold for at least the second period, said performing the beam failure recovery procedure is directly triggered without said performing beam switching and/or beam broadening being intermediately triggered, and when the beam quality falls below the first threshold for at least the first period without falling below the second threshold for at least the second period said performing beam switching and/or beam broadening is triggered.
A base station (BS) or user equipment (UE) for performing radio frequency beam management and recovery in communication with another UE/BS, wherein if the BS or UE is a BS, the other UE/BS is a UE and if the BS or UE is a UE, the other UE/BS is a BS, comprising:
- a memory, configured to store first and second thresholds and first and second periods respectively associated with the first and second thresholds;
- wherein the second threshold indicates a lower beam quality than the first threshold;
- a processor, configured to:
- evaluate a beam quality metric of a current beam against the first and second thresholds and the associated first and second periods;
- perform beam switching and/or beam broadening in response to determining the beam quality metric of the current beam falls below the first threshold for at least the first period;
- perform a beam failure recovery procedure in response to determining the beam quality metric of the current beam falls below the second threshold for at least the second period;
- and
- wherein said evaluating a beam quality metric of the current beam against the first and second thresholds and the first and second periods is performed in parallel such that when the beam quality falls below the second threshold for at least the second period, said performing the beam failure recovery procedure is directly triggered without said performing beam switching and/or beam broadening being intermediately triggered, and when the beam quality falls below the first threshold for at least the first period without falling below the second threshold for at least the second period said performing beam switching and/or beam broadening is triggered.
A non-transitory computer-readable medium having instructions stored thereon that are capable of causing or configuring a computing system to perform operations for performing radio frequency beam management and recovery in communication between a base station and a user equipment (UE), the operations comprising:
- configuring first and second thresholds,
- wherein the second threshold indicates a lower beam quality than the first threshold;
- configuring first and second periods respectively associated with the first and second thresholds;
- evaluating a beam quality metric of a current beam against the first and second thresholds and the associated first and second periods;
- performing beam switching and/or beam broadening in response to determining the beam quality metric of the current beam falls below the first threshold for at least the first period;
- performing a beam failure recovery procedure in response to determining the beam quality metric of the current beam falls below the second threshold for at least the second period;
- and
- wherein said evaluating a beam quality metric of the current beam against the first and second thresholds and the first and second periods is performed in parallel such that when the beam quality falls below the second threshold for at least the second period, said performing the beam failure recovery procedure is directly triggered without said performing beam switching and/or beam broadening being intermediately triggered, and when the beam quality falls below the first threshold for at least the first period without falling below the second threshold for at least the second period said performing beam switching and/or beam broadening is triggered.
