Abstract: Methods, systems, and devices for wireless communications are described that provide for resource allocation in an integrated access and backhaul (IAB) network. A relay node in an IAB network may be assigned a first resource partition that is different from a second resource partition for the child and parent nodes. Based on a resource configuration (e.g., for a slot) of the second resource partition, the relay node may opportunistically utilize the second resource partition for communications. For instance, the relay node may determine a direction table based on the resource configurations of the child and parent nodes, which may be used to perform uplink or downlink communications in one or more symbols of the second resource partition. The relay node may also identify flexible symbols as free or non-free when determining the direction table.

Abstract: Methods, systems, and devices for wireless communication are described. Some examples provide for identifying a primary synchronization signal (PSS) sequence of a synchronization subframe, determining, for the synchronization subframe, an extended synchronization signal (ESS) sequence based at least in part on the PSS sequence and transmitting the synchronization subframe. Other examples provide for generating an ESS sequence for a synchronization subframe to be communicated to a UE, scrambling the ESS sequence based at least in part on cell-specific information associated with the base station and transmitting, to the UE, the scrambled ESS sequence in the synchronization subframe.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. A wireless node may determine a connectivity state of the wireless node with respect to a wireless network, may determine a set of resources available for one or more synchronization communications based at least in part on the connectivity state, may select one or more resources from the set of resources, and may transmit the one or more synchronization communications using the one or more resources. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Examples may include receiving, at a user equipment (UE) a random access channel (RACH) configuration message from a base station, where the message indicates a channel metric (e.g., received signal strength indicator (RSSI), reference signal received power (RSRP), reference signal received quality (RSRQ), a signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), or the like) and a threshold associated with the channel metric. The, UE may measure a reference signal (e.g., synchronization signal block (SSB), channel state information reference signal (CSI-RS), or the like) and select a RACH procedure based on comparing the measured channel metric to the threshold. For example, the UE may select a two-step RACH procedure if the measured channel metric satisfies the threshold specified in the configuration. In some cases, the UE may select a RACH procedure or a listen-before-talk (LBT) procedure based on a QoS parameter.

Abstract: Methods, systems, and devices for wireless communications are described. A scheduled node may transmit, by a first node in the network and to a second node in the network, an indication of a first temporal pattern of communication states for communication by the first node on a first set of resources, the first node being configured for half-duplex communications. The scheduled node may receive, from the second node, a grant of resources for performing communications on a second set of resources that are multiplexed with the first set of resources in a frequency domain, a spatial domain, or a combination thereof.

Abstract: Aspects of the disclosure relate to improvements in random access procedures within a wireless communication network. To increase the likelihood that a user equipment (UE) will properly decode a random access response message from a base station, the base station may retransmit the random access response message one or more times. The number of retransmissions may be fixed or may be variable depending on whether the base station is able to receive or successfully decode a subsequently transmitted uplink message.

Abstract: Various aspects of the disclosure relate to communicating random access information and uplink control information. In some aspects, a user equipment (UE) or other suitable apparatus transmits physical uplink control channel (PUCCH) information concurrently with random access channel (RACH) information transmitted by another UE or other apparatus. For example, the RACH access information and the PUCCH information may be frequency division multiplexed orthogonal tones. The disclosure relates in some aspects to using downlink-uplink (DL-UL) channel reciprocity to determine symbol and/or tone locations. For example, a base station or other suitable apparatus may initially sweep across different directions in different time slots to transmit signals during a synchronization sub-frame. A UE or other suitable apparatus can then find an appropriate RACH symbol from its best synchronization beam index and transmit PUCCH information in those symbols.
