Abstract: The present disclosure describes a method, an apparatus, and a computer-readable medium for a random access channel (RACH) procedure at a user equipment. For example, the method may select a two-step RACH procedure or a four-step RACH procedure at the UE based at least on RACH configuration information received from a base station or the RACH configuration information at the UE. The example method may further include transmitting, from the UE, one or more messages associated with the two-step RACH procedure or the four-step RACH procedure based on the selection.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. A communication system may include a user equipment (UE) that receives a configuration for contention-free random access (CFRA) and a configuration for contention-based random access (CBRA). The UE determines a first random access resource. The first random access resource maps to one or more beams from a target base station. The UE determines a beam quality associated with the first random access resource. The UE initiates a random access request using the CFRA when the first random access resource is a contention-free resource, and the beam quality of the first random access resource is above a threshold beam quality. The UE initiates the random access request using the CBRA when the first random access resource is the contention-free resource, and the beam quality of the first random access resource is below the threshold beam quality.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, multi-link PDCCH monitoring. A UE may receive signaling configuring it to operate in at least one of a set of different modes of monitoring beam-pair links, wherein each beam-pair link comprises a transmit beam configured to be used by a base station (BS) for beamformed transmissions and a corresponding receive beam used by the UE. The UE may monitor at least two or more beam-pair links for downlink control channel transmissions based, at least in part, on the received signaling, and may transmit feedback to the BS based, at least in part, on the monitored beam-pair links.

Abstract: Techniques for performing reference signal measurement filtering in systems that support multi-beam operation are provided. A method for wireless communication by a base station (BS) includes determining at least one beam configuration for measuring reference signals transmitted from the apparatus, and signaling the beam configuration(s) to at least one user equipment (UE). A method for wireless communication by a UE includes receiving, from a BS, at least one beam configuration for measuring reference signals from the BS, and performing a measurement procedure for reference signals received from the BS based at least in part on the beam configuration(s).

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a UE. The apparatus switches from a first, active BWP to a second, active BWP. Then, the apparatus measures a first radio link quality of a configured CORESET TCI or a beam failure detection RS upon switching to the second, active BWP. For example, the apparatus may switch the active BWP based on detecting an expiration of a BWP inactivity timer. The apparatus may then determine based on a threshold radio link quality whether to perform a measurement of a second radio link quality of a beam failure recovery candidate resource set or to continue to monitor the configured CORESET TCI in the second, active BWP.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a first apparatus may detect a beam failure of a first link between the first apparatus and a second apparatus; transmit a beam failure recovery request indicating the beam failure of the first link, wherein the beam failure recovery request is transmitted via a second link of the first apparatus; and perform a beam failure recovery procedure, to select one or more beams for communication between the first apparatus and the second apparatus, based at least in part on transmitting the beam failure recovery request via the second link. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide information identifying a first time offset between a first time associated with a measurement performed by the user equipment and a second time associated with a measurement gap or a time value of a serving cell of the user equipment, receive information identifying a second time offset between the second time and a third time, wherein the second time offset is based at least in part on the first time offset, and/or transmit a random access message at the third time based at least in part on the second time offset. A scheduling entity may coordinate a random access procedure associated with the random access message based at least in part on the second time offset. Numerous other aspects are provided.

Abstract: In an aspect, a scheduled entity obtains a first set of indications associated with a beam failure recovery procedure, starts at least one of a first timer or a second timer based on the obtained first set of indications, and detects a radio link failure when the first timer expires or when the second timer expires. In some aspects, the scheduled entity starts at least one of the first timer or the second timer when N out-of-sync indications are obtained over a network configured time window, the N out-of-sync indications including aperiodic out-of-sync indications from the first set of indications and out-of-sync indications associated with a radio link monitoring procedure. In some aspects, the scheduled entity starts at least the second timer when the first set of indications includes a single aperiodic out-of-sync indication.

Abstract: Certain aspects of the present disclosure provide techniques for identifying a mismatch between a user's common search space (CSS) and user-specific search space (USS). A base station (BS) may receive an indication that a user equipment (UE) decoded at least one beamformed signal transmitted by the BS in a USS and did not decode at least one beamformed signal transmitted by the BS in a CSS. The BS may take one or more actions based, at least in part, on the indication. Similarly, a UE may decode at least one beamformed signal transmitted by a BS in a USS, transmit to the BS an indication that the UE decoded the at least one beamformed signal transmitted in the USS and did not decode at least one beamformed signal transmitted by the BS in a CSS, and take one or more actions based, at least in part, on the indication.
