Abstract: Certain aspects of the present disclosure provide techniques for application of a repetition factor to uplink (UL) control channels. A method that may be performed by a user equipment (UE) includes receiving, on a downlink (DL) control channel, an indication of a configuration for repetition of a UL control channel scheduled by the DL control channel and another UL control channel, wherein the configuration is applied for repetition of the other UL control channel after a configured time period starting from reception of the DL control channel; and transmitting the repetition of the UL control channel and the repetition of the other UL control channel in accordance with the configuration.

Abstract: Method and apparatus to provide an indication of a PUCCH repetition factor within DCI. The apparatus allocates downlink resources for at least one UE. The downlink resources comprising an indication of a PUCCH repetition factor within a DCI. The apparatus transmits the downlink resources to the at least one UE. The indication of the PUCCH repetition factor may comprises a dynamic indication or an implicit indication of the PUCCH repetition factor. The dynamic indication of the PUCCH repetition factor may be indicated in a separate bitfield within the DCI. The implicit indication of the PUCCH repetition factor may be based on a time domain resource allocation of an associated PDSCH.

Abstract: A base station determines a temporal filter configuration for a user equipment (UE) and transmits the temporal filter configuration to the UE. The temporal filter configuration indicates whether the UE should apply a temporal filter to channel state information (CSI) measurements to generate CSI values, or identifies which temporal filter to apply. The UE generates CSI values based on the temporal filter configuration and reports the generated CSI values to the base station.

Abstract: A random access procedure between a user equipment (UE) and a base station may include repetition of a random access message 3 based on an indication provided by a random access response (RAR) message including a physical downlink control channel (PDCCH) portion and a physical downlink shared channel (PDSCH) portion. The base station may transmit the RAR message to indicate at least one random access message 3 repetition parameter. The UE may determine at least one random access message 3 repetition parameter based on the RAR message. The UE may transmit the random access message 3 with repetition based on the message 3 repetition parameter, and the base station may receive the random access message 3 based on the repetition parameter, thereby improving coverage of the random access message 3.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting sounding reference signals (SRS) with (e.g., before or after) a random access channel (RACH) acknowledgement (ACK) (e.g., after Msg4). An example method by a user equipment (UE) includes receiving a first downlink RACH message, receiving a second downlink RACH message after the first downlink RACH message, receiving signaling that indicates the UE is to transmit SRS after the second downlink RACH message, and transmitting the SRS after the second downlink RACH message, in accordance with the indication.

Abstract: Aspects relate to random access messaging. A base station may transmit a first random access message (e.g., a random access channel (RACH) Msg2) to a user equipment. The first random access message may include an indication of at least one beam that the user equipment may use to transmit a second random access message (e.g., a RACH Msg3). The user equipment may then transmit the second random access message using a beam selected from the indicated at least one beam.

Abstract: Aspects of the present disclosure provide techniques for adjusting the density and/or number of random access channel (RACH) occasion for one or subset of synchronization signal block (SSB) beams from the plurality of available SSB beams. To this end, features of the present disclosure utilize a beam-specific bit-field that is transmitted by the base station to the user equipment (UE) that may indicate RACH occasion density for a SSB beam or a subset of SSB beams. In some aspects, the time and frequency resources for RACH occasion with beam-specific alternative density may be identified via the resources for general RACH occasions. Based on the adjusted RACH occasion density, the UE may select one or time and frequency resources to initiate access with the base station.

Abstract: In embodiments of systems and methods for managing communication between a wireless device and a base station, a base station may transmit Remaining Minimum System Information (RMSI) Downlink Control Information (DCI) indicating time and frequency resources for RMSI. A wireless device may receive a Channel State Indicator-Reference Signal (CSI-RS) based on the time and frequency resources for RMSI and may select a sub-beam of a beam associated with a synchronization signal block (SSB). The wireless device may send to the base station an indication of the selected sub-beam associated with the SSB in a Physical Random Access Channel (PRACH) message. The base station and the wireless device each may then perform an initial access procedure using the selected sub-beam to enable the wireless device to establish a communication link with the base station.

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: selecting a subset of a plurality of decoding candidates of a search space in a control channel based on a property of each of the subset of the plurality of decoding candidates; monitoring the subset of the plurality of decoding candidates; and decoding control information in the control channel based on the monitoring of the subset of the plurality of decoding candidates.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a set of aggregation levels for a set of physical downlink control channel (PDCCH) candidates within a search space. The UE may decode a first subset of PDCCH candidates, of the set of PDCCH candidates, that are each aggregated within a single PDCCH monitoring occasion, and a second subset of PDCCH candidates, of the set of PDCCH candidates, that are each aggregated across multiple PDCCH monitoring occasions. Numerous other aspects are described.
