Abstract: A user equipment (UE) may transmit a random access request message to a base station in a random access procedure to access a wireless network. In response, the base station may transmit a random access response message to the UE including an uplink grant for a first set of uplink resources for the UE to transmit a radio resource control (RRC) message. The UE may determine a second set of uplink resources for transmitting the RRC message, for example, based on additional uplink grants received in the random access response message. Additionally or alternatively, the UE may derive additional grants implicitly from the first uplink grant received from the base station. The UE may transmit the RRC message to the base station using the first and/or second sets of uplink resources and establish a connection based on the RRC message for subsequent uplink and downlink communications.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit downlink control information (DCI) messages to a user equipment (UE). A DCI message may be transmitted using a particular DCI format based on the type of control information included in the DCI message. In some cases, different types of control information may be transmitted using the same DCI format. In such cases, one or more bit fields in a DCI format may be useful to a UE for one type of control information but may not be useful to a UE for another type of control information. As described herein, in order to limit the overhead associated with control information transmissions, a base station may support techniques for utilizing these bit fields in a DCI format to transmit information corresponding to the type of control information being transmitted.

Abstract: Improved signaling of default and scheduled beams in a Channel Occupancy Time (COT) are provided through a base station that indicates a default or scheduled reception (Rx) or transmission (Tx) beam to a UE for use in the COT. As a result, the base station allows the UE to identify its default or scheduled Rx or Tx beam for its scheduled data at earliest at the beginning of the COT, without having to derive the beam from the QCL of the lowest CORESET ID in a dynamically indicated DCI of the latest monitored slot. The UE can thus more rapidly realize the default or scheduled Rx and/or Tx beam in high unlicensed bands (e.g. 60 GHz) and subsequently communicate with the base station in one or more COTs or a portion of a COT using the default or scheduled Rx or Tx beam.

Abstract: A configurable new radio (NR) resource scheduling and indication transmission procedure that may be executed by a base station and a user equipment (UE) is disclosed. For example, a base station may determine a number of synchronization signal blocks available for transmission of non-scheduling data, and transmit an indication signifying at least one of the number of synchronization signal blocks or a location of each of the number of synchronization signal blocks. Further, a UE may receiving an indication signifying at least one of a number of synchronization signal blocks or a location of each of the number of synchronization signal blocks. The UE may further determine one or more resource elements forming the number of synchronization signal blocks where non-scheduling data has been scheduled for transmission. The UE may receive the non-scheduling data within the one or more resource elements forming the number of synchronization signal blocks.

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: Certain aspects of the present disclosure provide techniques for user equipment (UE) antenna grouping for uplink transmission, such as dynamic antenna grouping for uplink transmission using multiple transmission configurations. A method that may be performed by a UE includes grouping one or more UE antennas into one or more groups and sending an indication of the one or more groups to a base station (BS). Another method that may be performed by a UE includes receiving an indication from a BS to group one or more UE antennas and grouping the one or more UE antennas based on the indication.

Abstract: Aspects described herein relate to configuring active spatial relations in wireless communications. A capability indicating a number of active spatial relations supported for detecting downlink reference signals or generating uplink beams can be indicated to an access point. A configuration of spatial relations indicating a transmit filter of reference signals for use in transmitting uplink communications can be received from the access point and based on the capability. One or more of the reference signals received from the access point can be detected based on the configuration.

Abstract: Networks that support 5G communication may support different numerologies across and even within a symbol, slot, or subframe. Sequences, such as reference signals or data scrambled with a scrambling code, may be transmitted on resources with such mixed numerologies. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment. The UE may be configured to receive an indication of assigned resources for communicating with a base station. The UE may also be configured to determine a numerology associated with the assigned resources, and to determine one or more indices based on the numerology. The UE may also generate a sequence based on the one or more indices and communicate with the base station based on the sequence.
