Abstract: A user equipment may receive a configuration that indicates a density of demodulation reference signal (DMRS) resource elements and a set of locations of the DMRS resource elements in one or more resource element groups associated with a physical downlink control channel (PDCCH); receive an indication of a change to at least one of the density of the DMRS resource elements or the set of locations of the DMRS resource elements, resulting in at least one of a modified density of the DMRS resource elements or a modified set of locations of the DMRS resource elements; and monitor for downlink control information in a search space associated with the PDCCH based at least in part on the at least one of the modified density of the DMRS resource elements or the modified set of locations of the DMRS resource elements.

Abstract: Generating, by a user equipment (UE) of a wireless access network, for a set of contention-based random access occasions of a base station of the network, a random number over an interval. For the generated random number meeting a threshold value within the interval, transmitting, by the UE and to the base station, a random access preamble within one of the random access occasions of the set. For the generated random number not meeting the threshold value, attempting, by the UE, contention-based access to the network within a subsequent set of random access occasions of the base station, the subsequent set of random access occasions occurring after the set of contention-based random access occasions of the base station.

Abstract: Wireless communications systems and methods related to a downlink search space with or without PDCCH monitoring aggregation in a wireless communication network are provided. A UE receives a monitoring configuration from a BS including a repetition of DCI over a plurality of PDCCH monitoring occasions of a search space. The monitoring configuration indicates one or more forms of diversity between PDCCH monitoring occasions. Diversity may be achieved, for example, by a CORESET frequency allocation difference, a PDCCH monitoring occasion frequency resource allocation difference, and/or different hashing functions for the CCE index of PDCCH monitoring occasions within a CORESET. Additional diversity is possible by using different beams and other methods. When activated either explicitly or implicitly, UE monitors for PDCCH transmissions from the first device utilizing the configured PDCCH monitoring aggregation.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes monitoring for a physical downlink control channel (PDCCH) in each of a plurality of monitoring occasions in a search space, wherein the PDCCHs are associated with the same downlink control information (DCI), and wherein the plurality of monitoring occasions are monitored using different beams; and decoding the PDCCHs after the monitoring.

Abstract: Various aspects pertain to a method for a UE to unilaterally initiate a request to a serving base station to change or enhance beam coverage at the UE. The UE may measure one or more characteristics of a directional beam transmitted by the base station and determines whether channel reliability for the beam should be improved. If channel reliability is below a threshold, then the UE may transmit a request to the base station seeking to adjust coverage of the beam (such as coverage enhancements). Such request may seek to adjust one or more transmit or receive parameters associated with the beam or channels transmitted therein. The UE may switch to using a pre-defined set of coverage enhancement parameters or procedures either automatically after transmitting the request or upon receipt of a grant by the base station.

Abstract: A UE may be configured to receive, from a base station, a downlink transmission on a downlink data channel including data and an indication of a beam switch; transmit first ACK feedback to the base station in response to receiving the data; and transmit second ACK feedback to the base station in response to receiving the indication of the beam switch, the second ACK feedback being separate from the first ACK feedback. A base station may be configured to transmit, to a UE, a downlink transmission on a downlink data channel including data and an indication of a beam switch; receive first ACK feedback from the UE in response to transmitting the data; and receive second ACK feedback from the UE in response to transmitting the indication of the beam switch, the second ACK feedback being separate from the first ACK feedback.

Abstract: A RAN node can indicate to a UE that a compact measurement report is to be used for beam measurements in a measurement report. A compact measurement report uses beam index numbers to indicate a position in a reference set. The reference set has a listing of resource indicators for beam measurements. As such, a reported beam measurement associated with a beam index number is also associated with the resource indicator positioned in the reference set indicated by the beam index number. The beam index numbers can be transmitted using fewer bits than are used for a resource indicator. The payload for a measurement report such as a L-SINR or L-RSP L1 measurement report is thereby reduced when the measurement report is transmitted as a compact measurement report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, via a physical broadcast channel message, an indication to attempt to decode, based at least in part on an assumption of an alternative size that is different from a default size, a downlink control information (DCI) message that schedules a remaining minimum system information (RMSI) transmission; and receive the RMSI transmission based at least in part on the DCI message. Numerous other aspects are provided.
