In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives N.sub.r1 RF signals at N.sub.r1 antennas on a first time-frequency resource. The N.sub.r1 RF signals carrying L layers of data generated at a base station. N.sub.r1 and L are positive integers. L is greater than N.sub.r1. The UE receives N.sub.r2 RF signals at the N.sub.r2 antennas on a second time-frequency resource. The N.sub.r2 RF signals carries the L layers of data. N.sub.r2 is a positive integer. The UE obtains N.sub.r1 baseband signals from the N.sub.r1 RF signals. The UE obtains N.sub.r2 baseband signals from the N.sub.r2 RF signals. The UE determines the L layers of data based on the N.sub.r1 baseband signals and the N.sub.r2 baseband signals.

Provided are a resource allocation method, a measurement method, a frequency domain resource determination method, a transmission method, and corresponding apparatuses and devices and a storage medium. The resource allocation method includes: sending by a first communication node, resource request information to a second communication node, where the resource request information includes first information; and/or receiving, by the first communication node, first resource allocation information sent by the second communication node, where the first resource allocation information includes second information, the first information and/or the second information includes information of a resource occupiable by a channel or signal between the first communication node and the second communication node and/or includes information of a resource occupiable by a channel or signal between the first communication node and one or more third communication nodes.

Prioritizing air interface resource allocation for relay nodes serving end-user wireless devices with higher bandwidth capabilities, such as 5G and beyond, versus relay nodes serving end-user wireless devices that do not have such capabilities. The bandwidth capability can be based on an average or threshold bandwidth capability of end-user wireless devices. Systems and methods disclosed are implemented in 5G EN-DC heterogeneous networks.

Embodiments include methods, performed by first node in an integrated access backhaul (IAB) network, for scheduling uplink (UL) transmissions in the IAB network. Such methods include receiving, from a first downstream node in the IAB network, a first buffer status report (BSR) indicating a first amount of UL data, with the first amount including UL data buffered at the first downstream node, and/or UL data expected to be received by the first downstream node. Such methods also include sending, to the first downstream node, a first UL resource grant indicating a time schedule of resources available for the first downstream node to transmit at least a portion of the first amount of UL data. In some embodiments, the first UL resource grant is sent after receiving the first BSR and without receiving a second UL resource grant from an upstream node in response to a second BSR.

A terminal according to the present invention includes an array antenna including an aperture, and an antenna pattern calculation unit. The antenna pattern calculation unit calculates antenna patterns of the array antenna that divide the aperture to correspondingly orient each of the aperture divisions toward a plurality of relay stations when control frames are received, and orient the aperture toward one of the plurality of relay stations when a data frame is received.

Aspects described herein relate to determining, by a node, to establish a first backhaul connection with a first upstream node for access link communications with a first downstream node, determining, by the node, to establish a second backhaul connection with a second upstream node for access link communications with a second downstream node, establishing the first backhaul connection with the first upstream node based on a first transmit/receive beam pair, and establishing the second backhaul connection with the second upstream node based on a second transmit/receive beam pair and while the first backhaul connection is established with the first upstream node.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for communicating, by a relay node, in a time division multiplexing (TDM) mode, with a parent node via a parent link configured between the relay node and the parent node and with a child node via a child link configured between the relay node and the child node, identifying a TDM alignment conflict between a first transmission scheduled for the parent link and a second transmission scheduled for the child link, and transmitting a conflict indication (e.g., a cancellation message or an interruption message) to the parent node or the child node.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may determine a forwarding direction for a set of resources based at least in part on time division duplexing (TDD) information associated with the set of resources. The forwarding direction may indicate a direction associated with forwarding signals carried in the set of resources. The repeater may receive a signal in the set of resources, the signal being provided by a first wireless communication device. The repeater may selectively forward the signal to a second wireless communication device based at least in part on the determined forwarding direction. Numerous other aspects are provided.

An ultrawideband radio transceiver/repeater provides a low cost infrastructure solution that merges wireless and wired network devices while providing connection to the plant, flexible repeater capabilities, network security, traffic monitoring and provisioning, and traffic flow control for wired and wireless connectivity of devices or networks. The ultrawideband radio transceiver/repeater can be implemented in discrete, integrated, distributed or embedded forms.
