Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive a random access channel (RACH) message. The base station may determine, based at least in part on the RACH message, whether the RACH message was transmitted directly to the base station by a user equipment (UE) or whether the RACH message was relayed from the UE to the base station via a millimeter wave repeater. The base station may perform a beam management procedure based at least in part on the determination. Numerous other aspects are provided.
Claims30
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a configuration that indicates at least one of a first resource set or a second resource set for beam management, wherein the first resource set is configured for beam management for a direct link between the UE and a network node, and the second resource set is configured for beam management for an indirect link between the UE and the network node via a millimeter wave repeater;
- receive at least one of a first message in the first resource set or a second message in the second resource set;
- and
- transmit a random access channel (RACH) message in a RACH occasion corresponding to the at least one of the first resource set or the second resource set based at least in part on receiving the at least one of the first message in the first resource set or the second message in the second resource set.
A millimeter wave repeater for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a configuration indicating a first random access channel (RACH) occasion for transmitting a power report;
- receive an input signal in a second RACH occasion different from the first RACH occasion;
- and
- transmit a power report associated with the input signal in the first RACH occasion, wherein the power report indicates whether a RACH message was relayed by the millimeter wave repeater in the first RACH occasion.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving a configuration that indicates at least one of a first resource set or a second resource set for beam management, wherein the first resource set is configured for beam management for a direct link between the UE and a network node, and the second resource set is configured for beam management for an indirect link between the UE and the network node via a millimeter wave repeater;
- receiving at least one of a first message in the first resource set or a second message in the second resource set;
- and
- transmitting a random access channel (RACH) message in a RACH occasion corresponding to the at least one of the first resource set or the second resource set based at least in part on receiving the at least one of the first message in the first resource set or the second message in the second resource set.
A method of wireless communication performed by a millimeter wave repeater, comprising:
- receiving a configuration indicating a first random access channel (RACH) occasion for transmitting a power report;
- receiving an input signal in a second RACH occasion different from the first RACH occasion;
- and
- transmitting a power report associated with the input signal in the first RACH occasion, wherein the power report indicates whether a RACH message was relayed by the millimeter wave repeater in the first RACH occasion.
