    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: User equipment (UE)-specific information may be transmitted within a control resource set configured to carry resources common to UEs within a system. The UE-specific information may be associated with a search space having an aggregation level different from aggregation levels used with the common control resources and may occupy different modulation symbols within the common control resource set (e.g., to support flexible scheduling for multiple UEs). A base station and UE may operate in a system using one or more control resource sets within a system bandwidth. The UE may detect common control resources by monitoring decoding candidates in the control resource set according to a first set of aggregation levels. The UE may detect UE-specific control resources by monitoring decoding candidates in the control resource set according to other aggregation levels. The UE and base station may communicate based on control information obtained from the monitoring.

    Abstract: A RACH preamble is transmitted from a UE using multiple antenna ports. A UE splits a data stream containing a RACH preamble into multiple streams corresponding to a same number of antenna ports of the UE. The UE multiplexes the copies of the RACH preamble according to a multiplexing scheme that enables a receiving eNB to discern the different channels used to transmit the signal from the different antenna ports. A RACH procedure is further accomplished in two steps instead of four by the UE then splitting a RACH payload to the same number of streams and multiplexing the RACH payload for transmission to the eNB. The eNB receives both transmissions, and may use the RACH preamble as a reference signal, and responds with a combined message with control information, random access response, and contention resolution information.
