Abstract: Certain aspects of the present disclosure provide techniques for transmitting a random access channel (RACH) preamble. For example, certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes generating a message comprising a random access channel (RACH) preamble, determining an order of a plurality of beams for transmitting the message based on an indication of the order, and transmitting the message, to a network node, via the plurality of beams in accordance with the determined order of the beams.

Abstract: In wireless communication systems that support 5G or NR protocols, subframes used for communication may have different numerology options. Numerology options may refer to the characteristics of the subframe such as a tone spacing within each symbol of the subframe, a symbol duration for each symbol of the subframe, a number of symbols in the subframe, etc. A subframe may include a control channel (e.g., the PDCCH) and a data channel (e.g., the PDSCH). In an aspect, the control channel and the data channel within the subframe may have different numerologies. As such, a need exists to signal the numerology of the subframe to users and to determine whether and how to multiplex the control channel and the data channel into the subframe.

Abstract: Uplink transmission power levels may be adjusted in response to changes in a directional beam used for wireless communications. A beam change may be identified, wherein the beam change includes a transition from a first transmission configuration based on a first beam direction of a cell to a second transmission configuration based on a second beam direction of the cell. A downlink (DL) message associated with the beam change may be received, wherein the DL message comprises a transmission power indication. An uplink (UL) message may be transmitted at a power level based at least in part on the transmission power indication.

Abstract: Certain aspects of the present disclosure provide techniques for assisted power control for an uplink signal transmitted during a RACH procedure. A UE may determine a transmit power for transmitting a message during a RACH procedure with a secondary BS, based at least in part, on communication between the UE and a primary BS. The UE may transmit the message to the second BS during the RACH procedure based, at least in part, on the determined transmit power.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a beam failure condition. The UE may determine whether a reference signal beam satisfies a beam strength threshold. The UE may transmit, based at least in part on a result of the determining, a beam failure recovery (BFR) signal using resources associated with the reference signal beam.

Abstract: Methods, systems, and devices for wireless communications are described that provide for signaling and switching of beam pair links (BPLs) for directional transmission beams between a base station and a user equipment (UE). A threshold value may be determined, which corresponds to an amount of time for a UE to receive and decode control information, and apply a different BPL than a current BPL that that is in use. The UE may maintain a BPL for data, which is used during data transmission time intervals (TTIs) until an indication is received to change the BPL for data. The UE and the base station may determine to change between BPLs based at least in part on the threshold value and a scheduling offset between a control channel transmission that allocates resources for a data TTI and a start of the data TTI.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify a set of power configurations for a plurality of communications with at least one target device. The set of power configurations may be based at least in part on a type of signal, a type of channel, a parameter of the wireless device, a parameter of the target device, or a combination thereof. The wireless device may then determine a duplexing mode for the plurality of communications based at least in part on the set of power configurations. The duplexing mode may be, for example, a full duplex mode or a half-duplex mode. The wireless device may then transmit the plurality of communications to and/or receive the plurality of communications from the at least one target device according to the set of power configurations and the selected duplexing mode.

Abstract: Techniques are described for wireless communication. One method includes performing a first beam sweep procedure to determine a first beam pair that includes a transmit beam of a first wireless node and a receive beam of a second wireless node, identifying a level of correspondence at one or both of the first wireless node and the second wireless node, the level of correspondence being between a transmit beam and a receive beam of a respective wireless node and determining, based on the level of correspondence, a range of a second beam sweep procedure to be performed in determining a second beam pair that includes a transmit beam of the second wireless node and a receive beam of the first wireless node.

Abstract: Techniques for procedures using request to send/clear to send (RTS/CTS) procedures and multiple timers are described. A RTS/CTS procedure using multiple timers may use a first timer and a second timer. The first timer may be associated with a duration to transmit and receive a request to send (RTS) message and a clear to send (CTS) message. The second timer may be associated with a duration to transmit a data message. A network device may transmit a RTS message to request communication resources to transmit data. If the CTS message is not received prior to the expiration of the first timer, neighboring network devices may determine that the communication resources were not allocated and may attempt to request the newly available resources. If a CTS message is received, the network device may communicate the second timer data to the neighboring network devices in a variety of ways.
