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: Methods, systems, and devices for wireless communication are described. In some wireless systems, a user equipment (UE) may access a network or cell using a random access (RACH) procedure. A base station may allocate dedicated RACH resources and common RACH resources for the UE to transmit a RACH preamble message on and may convey a configuration for the UE. In some cases, the UE may perform multiple transmissions of the RACH preamble message in the dedicated RACH resources, and based on the configuration may determine whether to perform a single or multiple transmissions of the RACH preamble message in the common RACH resources. The UE may transmit the messages using the same or different uplink transmit beams, and the base station may receive the messages using the same or different uplink reception beams. These multiple transmissions may reduce latency and improve reliability of the RACH procedure.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to semi-persistent configuration of reference signals (RSs), such as measurement reference signals (MRSs) for beam refinement. An example method generally includes transmitting, to a user equipment (UE), a reference symbol (RS) configuration, wherein transmitting the RS configuration is independent of activating RS training for the UE, transmitting, to the UE, a message indicating an activation of RS training subsequent to transmitting the RS configuration, transmitting RSs to the UE periodically based on the RS configuration, and receiving, from the UE, measurement reports based on the transmitted RS.

Abstract: Certain aspects of the present disclosure provide techniques for assisting a UE in measuring reference signals in a wireless communication system using beams. A BS may transmit, to a UE, information regarding one or more measurement gaps for measuring one or more reference signals. The BS may transmit, to the UE, additional information regarding at least one of direction information associated with the one or more reference signals or rank indication to be used by the UE to measure the one or more reference signals during the one or more measurement gaps. A UE may perform corresponding operations.

Abstract: Aspects of the present disclosure relate to techniques for multibeam PDCCH monitoring during CDRX operations. A BS may determine a configuration of one or more beams for a UE to monitor for receiving a downlink control channel from the BS, wherein the configuration is based, at least in part, on a monitoring window since the subframe in which the downlink control channel (e.g., PDCCH), indicates an initial UL, DL, or SL use data transmission for the UE. The BS may transmit, to the UE, an indication of the configuration. A UE may perform corresponding operations and may monitor one or more beams based on the received configuration.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for beam sweeping for control and data transmissions. In certain aspects, the method for use by a first wireless communications device includes determining one or more beams in a sequence of beams for use in sending or receiving directional transmissions to a second wireless communications device and sweeping through the one or more beams in the sequence of beams for transmissions to or from the second wireless communications device between beamforming training procedures performed with the second wireless communications device.

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: The present disclosure describes a method, an apparatus, and a computer-readable medium for wireless communications at a user equipment. For example, the method may receive a numerology of a signal received from a base station, wherein the numerology indicates one or more parameters of a waveform associated with the signal. The example method may further perform a rate matching based at least on the numerology, wherein the rate matching is performed for decoding the signal received from the base station. Additionally, in another example, a method for wireless communications at a base station is provided. The method includes performing a rate matching at the base station based at least on a numerology which is known at the base station. The rate matching is performed for decoding the signal received from a user equipment.
