Abstract: Methods, systems, and devices for wireless communications are described in which a paging configuration may be provided by a base station that indicates one or more occasions during which a user equipment (UE) is to monitor for pages. A location of the paging occasion may be based at least in part on at least one synchronization signal block (SSB) transmitted by the base station. A mapping between a paging occasion index and the location of the paging occasion is indicated in the paging configuration. Paging windows may be configured during downlink slots that contain an SSB transmission. Paging transmissions may use beamforming parameters that are the same as SSB transmission beamforming parameters.

Abstract: An apparatus are provided for wireless communication at a base station with improved PBCH construction and decoding. The base station apparatus constructs a PBCH payload, wherein a bit location is selected for encoding a plurality of bits of the PBCH based on an estimated reliability for the corresponding bits location wherein the plurality of bits comprises frozen bits, unknown bits that are unknown to a user equipment, and potentially known bits that are potentially known by the user equipment. The apparatus transmits the PBCH payload in at least one of a plurality of SS blocks. A UE receiving the PBCH decodes the PBCH based on a successive decoding order. The successive decoding order may be based on an estimated reliability for the corresponding bits, e.g., in which potentially known bits are decoded prior to unknown bits.

Abstract: An intermediary base station supporting mobile terminal (MT) functionality and/or a user equipment (UE) may receive a time alignment (TA) command and associated timer value from one or more distributed units (DUs) and/or a central unit (CU) of a parent base station. The TA command and timer value may be based on an experienced or potential timer expiration associated with a TA of a communication link. The TA command may specify an updated TA value and a timer reset for scheduling communications on the communication link. In some examples, the TA command may be in response to a TA command request provided by the MT or UE on allocated resources or configurations indicated by the parent base station. In other cases, the TA command may be in response to a random access procedure on allocated resources or configurations indicated by the parent base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a first type of timing advance indicator, wherein the first type of timing advance indicator is associated with a first type of connection associated with a first group of wireless nodes, of a network, that includes the first wireless node and the second wireless node and is different from a second type of timing advance indicator used for a second type of connection associated with a second group of wireless nodes of the network. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node based at least in part on the first type of timing advance indicator. Numerous other aspects are provided.

Abstract: A relay node supporting mobile terminal (MT) functionality and distributed unit (DU) functionality may receive a timing advance (TA) value for uplink synchronization associated with a timing alignment timer from a parent node. In some cases, the timing alignment timer may expire prior to the relay node receiving a next TA value. Upon expiration of the timing alignment timer, the relay node may initiate a second timer (e.g., a transition timer) associated with the transitioning of a DU entity of the relay node to a DU transition state. The DU transition state is associated with certain DU behavior for serving child nodes while the transition timer is active. Configuration of the DU transition state may be identified by the relay node, or received from a parent node. In cases where the transition timer expires prior to receiving a next TA value, the DU may declare a loss of uplink synchronization.

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: A base station central unit (CU) may receive a measurement report from one or more user equipments (UEs). The CU may identify a scheduling plan indication (SPI) for one or more scheduling nodes in a network, based at least in part on the received measurement reports. The SPI may specify a pattern of scheduling states, over a period of time, to be used by the one or more scheduling nodes to schedule communication resources for one or more UEs in the network. The scheduling states may (e.g., based on an interference profile determined from the received measurement reports) specify UEs or other communication resources for transmission scheduling decisions made by the scheduling nodes, or may specify beam patterns for beamforming procedures performed by the scheduling nodes. In some cases, the scheduling nodes may identify tentative SPIs, which the CU may pass amongst other scheduling nodes for distributed scheduling coordination schemes.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. A wireless node may determine a pattern for transmitting multiple synchronization communications in one or more synchronization communication sets. The wireless node may determine a set of resources, in the one or more synchronization communication sets, to be used to transmit the multiple synchronization communications based at least in part on the pattern. The wireless node may transmit the multiple synchronization communications using the set of resources. A first synchronization communication, of the multiple synchronization communications, may be frequency division multiplexed with a second synchronization communication. Numerous other aspects are provided.
