Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: Methods and apparatuses for wireless communication are provided. A transmitting apparatus receives an indication to use multiple subframes to send uplink control information, codes the uplink control information over the multiple subframes based on the indication, and sends the coded uplink control information via the multiple subframes. Sending the coded uplink control information includes transmitting acknowledgement information (ACK) of a current downlink-centric self-contained subframe in an uplink acknowledgement portion of the current downlink-centric self-contained subframe, bundling ACK bits of multiple downlink-centric self-contained subframes and encoding the bundled ACK bits to generate parity acknowledgement bits associated with systematic acknowledgement bits, transmitting the systematic acknowledgement bits in each uplink acknowledgement portion of the multiple downlink-centric self-contained subframes, and transmitting the parity acknowledgement bits associated with the acknowledgement information bits of the multiple downlink-centric self-contained subframes in an uplink-centric self-contained subframe that is sequentially subsequent to the multiple downlink-centric self-contained subframes.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless systems, a user equipment (UE) may access a network or cell using a random access (RACH) procedure. A base station may allocate dedicated RACH resources and common RACH resources for the UE to transmit a RACH preamble message on and may convey a configuration for the UE. In some cases, the UE may perform multiple transmissions of the RACH preamble message in the dedicated RACH resources, and based on the configuration may determine whether to perform a single or multiple transmissions of the RACH preamble message in the common RACH resources. The UE may transmit the messages using the same or different uplink transmit beams, and the base station may receive the messages using the same or different uplink reception beams. These multiple transmissions may reduce latency and improve reliability of the RACH procedure.

Abstract: Techniques are described for wireless communication. In one method, a user equipment (UE) receives a timing synchronization signal (TSS) and a physical broadcast channel (PBCH), with the TSS based at least in part on a timing of the TSS within a broadcast channel transmission time interval (BCH TTI); determines the timing of the TSS within the BCH TTI; and demodulates the PBCH based at least in part on the TSS. In another method, a base station allocates resources for a TSS and a PBCH within a BCH TTI; determines the TSS based at least in part on a timing of the TSS within the BCH TTI; and transmits, on the resources allocated for the TSS and the PBCH, the TSS and the PBCH, with the TSS transmitted as a demodulation reference signal (DMRS) for the PBCH on at least one port used to transmit the TSS and the PBCH.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving a PDCCH order for a MSG 1 transmission having a first DMRS that is quasi co-located with a first reference signal, and receiving a corresponding RACH message having a second DMRS that is quasi co-located with a second reference signal, wherein the first reference signal and second reference signal are different.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may configure an operation mode associated with releasing soft resources associated with an integrated access backhaul (IAB) network that supports implicit release of soft resources and explicit release of soft resources. The node may provide information that identifies the operation mode. Numerous other aspects are provided.

Abstract: Backhaul resources may be allocated to different wireless communication links between different base stations, and local redistribution of resources among base stations may be utilized to account for variations in signal quality and/or variations in traffic experienced by different nodes of the backhaul network. A first access node function (ANF) may determine a need for additional backhaul resources, and may transmit a request message to one or more user equipment functions (UEFs) for additional backhaul resources. A UEF that receives the request message may forward the request to an associated second ANF. The second ANF, if it has backhaul resources available that the first ANF can use, may send a response to the first ANF, via the associated UEF, and the first ANF may use the additional resources that were originally allocated to the second ANF.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication regarding one or more signals associated with beam management, the indication indicating one or more future time periods for which the UE may not receive one or more transmissions of the one or more signals. The UE may configure a beam management configuration of the UE based at least in part on the indication. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods and apparatus for wireless communications that support fallback from a 2-step to a 4-step random access procedures. A user equipment (UE) may establish a connection with a base station using a random access procedure. The random access procedure may be a 2-step random access procedure and reduce a number of handover exchange messages. The 2-step random access procedure may include the UE transmitting, to the base station, a first random access message including a preamble and a payload. In some implementations, the base station may receive the preamble but fail to receive or decode the payload. The random access procedure may utilize the received preamble information instead of performing retransmission of the first random access message. The base station may transmit a second random access message to the UE indicating, explicitly or implicitly, a fallback to a 4-step random access procedure for connection establishment.
