    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 directional primary synchronization signals (DPSSs). A UE or other suitable apparatus can then find an appropriate RACH symbol from its best DPSS beam index and transmit PUCCH information in those symbols.

    Abstract: A UE may receive a directional synchronization subframe from a base station and transmit a scheduling request to the base station during a time period based on the directional synchronization subframe. The scheduling request may enable a base station to grant the UE resources to send a buffer status report (BSR). The time period may be associated with a random access channel (RACH) time period. The UE may also transmit a scheduling request within a frequency region of the RACH time period. The scheduling request may be transmitted based on a received indication of a set of subcarrier, a cyclic shift, or a sequence index. In some examples, the resources used by the UE to send the BSR may include physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) resources.

    Abstract: Methods, systems, and devices for wireless communication are described that provide for establishment of communication links between nodes in a wireless network, in which an access node (e.g., a node that provides access to a core network) may provide a communication link configuration and resources for communications between multiple nodes. In some cases, an access node may receive a request from a first node to establish a communication link with a second node. The communication link may be, for example, a directional transmission beam that carries data or control information, or a combination thereof, between the first node and the second node. The access node may determine the communication link configuration based on one or more link measurements provided by the first node or second node, and provide the configuration information to one or both of the first node or the second node.

    Abstract: A wireless node (e.g., a slave relay node) may receive scheduling commands over multiple wireless links and identify a scheduling conflict. For example, the wireless node my identify a conflict of wireless resources indicated by the received scheduling commands. The wireless node may select a non-conflicting subset of the scheduling commands based on a conflict policy, and transmit data over the wireless links according to the non-conflicting subset of the scheduling commands. Additionally or alternatively, the wireless node may transmit a conflict report indicating the identified scheduling conflict. The conflict report may be sent to other wireless nodes (e.g., master relay nodes associated with the conflicting scheduling commands). The other wireless nodes may engage in negotiation signaling to resolve the scheduling conflict, and may transmit an updated scheduling command to the slave relay node. The slave relay node may transmit data over wireless links based on the updated scheduling command.

    Abstract: Methods, systems, and devices for wireless communication are described. A first wireless node may establish a wireless connection between the first wireless node and a second wireless node in a wireless backhaul communications network. The first wireless node may identify, at the first wireless node, a need for additional resources for wireless communications with a third wireless node. The first wireless node may transmit a request message to the second wireless node indicating that resources are requested at the first wireless node. The first wireless node may receive an indication of one or more available resources from the second wireless node. The first wireless node may select one or more of the available resources for wireless communications with the third wireless node.
