Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication with a network. In some aspects, the scheduled entity transmits a message that requests a scheduling entity to transmit at least one reference signal. The scheduled entity obtains channel state information based on the at least one reference signal. The scheduled entity transmits a report that includes the channel state information. In other aspects, the scheduled entity transmits a message that requests a scheduling entity to schedule a reference signal transmission for the scheduled entity. The scheduled entity obtains an assignment of resources for transmission of the reference signal in response to the message. The scheduled entity transmits the reference signal based on the assignment of resources. Other aspects, embodiments, and features are also claimed and described.

Abstract: One apparatus may determine a first set of parameters associated with a first RACH procedure, the first set of parameters being associated with beam failure recovery for a first UE in a cell. The apparatus may send the first set of parameters to the first UE. Another apparatus may receive the first set of parameters associated with a first RACH procedure. The other apparatus may receive, from the first apparatus, a second set of parameters associated with a second RACH procedure. The other apparatus may generate a RACH preamble based on the first set of parameters or based on the second set of parameters. The other apparatus may send, to the first apparatus, the generated RACH preamble.

Abstract: An apparatus may determine whether to indicate a beam failure recovery request to a base station using a contention-free RACH procedure with a dedicated preamble when the UE is timing unsynchronized with the base station. The apparatus may perform, when the apparatus is timing unsynchronized with the base station, the contention-free RACH procedure with the dedicated preamble to indicate the beam failure recovery request when the beam failure recovery request is determined to be indicated to the base station using the contention-free RACH procedure with the dedicated preamble. The apparatus may perform, when the apparatus is timing unsynchronized with the base station, a contention-based RACH procedure to indicate the beam failure recovery request when the beam failure recovery request is undetermined to be sent to the base station using the contention-free RACH procedure with the dedicated preamble.

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: 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.
