Abstract: Certain aspects of the present disclosure provide techniques for performing, by a user equipment (UE), radio link monitoring based on discontinuous reception mode operation of the UE. Certain aspects provide a method for wireless communication. The method generally includes operating, at a user equipment (UE), in a discontinuous reception (DRX) mode of operation. The method further includes evaluating, by the UE, link quality between the UE and a base station (BS) at least once every time period, wherein the time period is based on a length of a DRX cycle of the UE operating in the DRX mode of operation and a reference signal (RS) period, wherein the BS is configured to transmit RS periodically every RS period.

Abstract: Certain aspects of the disclosure provide techniques for a user equipment (UE) to determine a receive beam of a plurality of receive beams for receiving an upcoming transmission from a base station, wherein the determining is based on whether an indication is received from the base station indicating if the upcoming transmission includes a reference signal (RS) multiplexed with additional data. The techniques further provide for the UE to receive the upcoming transmission using the determined receive beam.

Abstract: A UE may receive a beam modification command that indicates a set of transmit beam indexes corresponding to a set of transmit beams of a base station, and each transmit beam index of the set of transmit beam indexes may indicate at least a transmit direction for transmitting a transmit beam by the base station. The UE may determine a set of receive beam indexes corresponding to receive beams of the UE based on the set of transmit beam indexes, and each receive beam index of the set of receive beam indexes may indicate at least a receive direction for receiving a receive beam by the UE. The UE may receive, from the base station, a signal through at least one receive beam corresponding to at least one receive beam index included in the set of receive beam indexes.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for determining a maximum transport block size. In certain aspects, a method comprises receiving, from a user equipment (UE), information indicative of a size of a buffer at the UE for storing data received from the BS. The method further includes determining a maximum transport block size based on the size of the buffer at the UE and a number of hybrid automatic repeat request (HARQ) processes used by the BS to send data to the UE. The method further comprises transmitting a transport block with a size not exceeding the maximum transport block size to the UE.

Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Abstract: Aspects of the present disclosure relate to receiver beamforming for serving and neighbor cell measurements. An exemplary method generally includes communicating with one or more base stations using a first beam type, initiating a transition to communicating with at least one of the one or more base stations using a second beam type in response to an indication of a trigger event, and communicating with the at least one of the one or more base stations using the second beam type.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a UE. The apparatus may receive a message from a base station. The message may indicate a first dedicated resource for downlink transmission, and the first dedicated resource may be associated with a scheduled downlink transmission from the base station. The apparatus may determine a second dedicated resource for uplink transmission based on the first dedicated resource for downlink transmission indicated in the message. The second dedicated resource for uplink transmission may be associated with the scheduled downlink transmission. The apparatus may determine whether to transmit an information message, to be used by the base station for transmitting the scheduled downlink transmission, on the second dedicated resource.

Abstract: Various features related to using a multi-port synchronization signal as reference for demodulating a multi-port broadcast channel are described. In an aspect, a synchronization signal, e.g., SSS, may be repurposed to serve as a demodulation reference for a downlink channel, e.g., PBCH, thereby obviating the need for a base station to send an additional reference signal for PBCH demodulation. A base station may select two or more logical antenna ports to transmit a synchronization signal, transmit the synchronization signal from the selected two or more logical antenna ports, and transmit information on the PBCH, from at least the selected two or more logical antenna ports. A UE may receive the synchronization signal from the two or more logical antenna ports at the base station, receive information on the PBCH from the at least the two or more logical antenna ports, and demodulate the information based on the received synchronization signal.
