    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support marking symbols and validation of non-cell-defining-synchronization signal block (NCD-SSB) and random access channel (RACH) occasions within 5G new radio (NR) networks. In a first aspect, a method of wireless communication includes the UE obtaining an uplink-downlink configuration for one or more slots, an NCD-SSB configuration identifying NCD-SSB transmissions, and a bandwidth configuration identifying a bandwidth part (BWP) allocated to the UE and a configuration for cell-defining-synchronization signal block (CD-SSB) transmissions. The UE can mark a configured flexible symbol as a downlink symbol in response to either an NCD-SSB symbol or a CD-SSB symbol overlapping with the flexible symbol. Other aspects and features are also claimed and described.

    Abstract: Methods, systems, and devices for wireless communications are described. The network may configure a user equipment (UE) with measurement objects indicating the synchronization signal blocks (SSB)s to be measured for neighbor cells. A UE may receive control signaling from the network indicating a switch from a first bandwidth part (BWP) to a second BWP. The first BWP may be associated with a first cell measurement type for neighbor cells (e.g., inter-frequency or intra-frequency) and a first reference SSB. The second BWP may be associated with a second, different, cell measurement type for neighbor cells and a second, different, reference SSB. After the BWP switch, the UE may perform measurements on SSBs associated with neighbor cells based on the second cell measurement type.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central entity may determine a set of schedulable resources for a plurality of links associated with a plurality of nodes of a multi-link network; and may provide scheduling information to the plurality of nodes to schedule communication on the plurality of links based at least in part on determining the set of schedulable resources. In some aspects, a node of a network may determine an extended slot format indicator for the node based at least in part on a received extended slot format indicator of a parent node of the node and a received null adjust request from a child node of the node; may provide the determined extended slot format indicator to the child node; and may provide the received null adjust request to the parent node. Numerous other aspects are provided.

    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.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for system information (SI) for access and backhaul. An access node (AN) may provide SI to devices within its cell indicating communication procedure configurations. The AN may provide SI to devices that is specific to whether the communication procedure is an access procedure or a backhaul procedure. The AN may transmit a common master information block (MIB) directing the devices within its cell to a search space in order to receive the remaining SI. The search space may be shared between access devices and backhaul devices or alternatively may be separate between access and backhaul devices. The remaining SI may not be shared between access and backhaul devices. The devices may determine different configurations as defined by the SI from the AN for communications procedures based on whether the procedure is an access procedure or a backhaul procedure.
