    Abstract: Methods, systems, and devices for multiple random access channel (RACH) message 1 (Msg1) transmission for physical downlink control channel (PDCCH) ordered RACH are described. A user equipment (UE) may perform the multiple Msg1 transmission as part of a CFRA or CBRA procedure for access. The UE may perform the multiple Msg1 transmissions in a cyclic consecutive manner during configured RACH occasions or according to explicit time and frequency indications of a random access response (RAR) window. Based on the multiple Msg1 transmission procedure, the UE may reduce latency for random access procedure on the RACH and improve signaling throughput. In some cases, the UE may support beam correspondence and may perform multiple Msg1 transmissions to enhance multi-beam diversity during RACH transmission by performing transmission corresponding to RACH occasions mapped to different synchronization signal blocks (SSBs).

    Abstract: Methods, systems, and devices for wireless communications are described that provide for identification of beamforming parameters for a downlink transmission beam based at least in part on a set of rules that define a priority order for control transmission and data transmissions. Downlink resources may be allocated to a user equipment (UE) for a downlink transmission via a first set of downlink beamforming parameters, and the UE may also be configured to monitor a control resource set using a different set of downlink beamforming parameters within a same transmission time interval (TTI) as the downlink transmission. A UE and a base station may identify which beamforming parameters to use for the downlink transmission based on the priority order. The set of rules may define which set of downlink beamforming parameters are to be used, whether the downlink transmission is rate-matched around the control resource set, or combinations thereof.

    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: Certain aspects of the present disclosure relate to communication systems, and more particularly, to sending and monitoring for a decoding candidate. Certain aspects provide a method for decoding information sent via a wireless transmission. The method generally includes receiving an indication of an association between a first decoding candidate and a second decoding candidate, monitoring the first decoding candidate in a search space of a first set of resources, the first decoding candidate received from a wireless node, and monitoring the second decoding candidate in a search space of a second set of resources, the second decoding candidate received from the wireless node, wherein the monitoring of the second decoding candidate is based on the association between the first and second decoding candidates.

    Abstract: Methods, systems, and devices for wireless communications are described that provide staggered synchronization signal blocks (SSBs) in frequency sub-bands for beamformed wireless communications. Transmissions of SSBs and control channel transmissions (e.g., remaining minimum system information (RMSI) physical downlink control channel (PDCCH) transmissions) may use multiple transmission beams in a beam sweeping procedure. The SSB transmissions may be transmitted using transmission beams that span one frequency sub-band of a number of available frequency sub-bands, and the control channel transmissions may use transmission beams that span two or more of the frequency sub-bands. The SSB beam sweeping procedure may be performed separately during staggered, non-overlapping time periods for each frequency sub-band of the number of frequency sub-bands. Each of the of SSBs may indicate a reference timing of the base station used to identify a set of resources (e.g., a control resource set (CORESET)) that carries control channel transmissions.
