Described techniques provide for increased occasions at which a SRS may be transmitted, enhance likelihood of a successful listen-before-talk (LBT) procedure, or any combinations thereof.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement improved RAR decoding performance and resource utilization efficiency in a RACH procedure. A PDCCH with common search space encodes a DCI with configuration information that schedules separate PDSCHs for different UEs/UE groups. When sending a RAR message, the PDCCH includes a DCI with a configuration field to signal multiple DMRS resources with corresponding PDSCH. Each sub-field of the configuration field may include one or multiple bits. When one bit per sub-field, the bit is a flag that when asserted leads the UE to blind decode the PDSCH associated with that DMRS resource. When multiple bits, it includes a flag field as well as one or more bits that include least significant bits of a UE identifier (or group identifier). The UE locates its identifier (or group identifier), and limits decoding to that PDSCH with corresponding DMRS resource.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for selecting a beam to be allocated for transmitting downlink (DL) data to user equipment (UE). In some implementations, a UE receives a reference signal on each of a number of beams associated with a base station, and determines a delay spread value for each beam. The UE identifies each beam for which the determined channel delay spread value is less than a threshold value, and determines a reference signal received power (RSRP) level for each identified beam. The UE transmits an indication of the determined RSRP levels of the identified beams to the base station, and receives, in response to the transmitted indication, a selection of the beam to be allocated for DL transmissions to the UE.
