Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may transmit configuration information indicating a first precoding matrix indicator (PMI) parameter and a second PMI parameter, wherein the first PMI parameter is associated with non-simultaneous activity of a distributed unit (DU) and a mobile termination (MT), and wherein the second PMI parameter is associated with simultaneous activity of the DU and the MT. The wireless node may perform a communication in accordance with a selected PMI parameter of the first PMI parameter and the second PMI parameter based at least in part on whether the DU and the MT are simultaneously active. Numerous other aspects are described.

A method, performed by a user equipment (UE), in a wireless communication system is provided. The method includes transmitting, to a base station (BS), UE capability for physical downlink shared channel (PDSCH) reception, receiving, from the BS, configuration information related to control information, receiving, from the BS, the control information based on the configuration information, identifying that information related to transmission configuration indication (TCI) state is not included in the received control information, determining whether PDSCH transmission scheduled by the control information is based on single-transmission and reception point (TRP) or multi-TRP, and receiving, from the BS, the scheduled PDSCH based on the determination.

When a plurality of apparatuses each having a role of establishing a wireless network performs, in parallel, communication with a first apparatus having a role of joining a wireless network via a plurality of transmission channels, a communication apparatus controls, based on acquired information about a communication quality in communication between a second apparatus included in the plurality of apparatuses and the first apparatus, a transmission output of at least the second apparatus such that a difference between a communication quality in communication between an apparatus included in the plurality of apparatuses and different from the second apparatus and the first apparatus and a communication quality in communication between the second apparatus and the first apparatus becomes smaller. Alternatively, the communication apparatus determines at least one of a coding rate and a modulation scheme for use in communication between the second apparatus and the first apparatus based on the information.

A method of controlling communications within a wireless communications network is provided. The method comprises receiving, at a first infrastructure equipment acting as a donor node connected to a core network part of a wireless communications network, signals representing data from one or more others of infrastructure equipment, the data having been received at the one or more others of the infrastructure equipment from one or more communications devices or from other infrastructure equipment, and transmitting, by the first infrastructure equipment, the data from the one or more others of the infrastructure equipment to the core network part of the wireless communications network. At least one of the infrastructure equipment uses at least one spectral efficiency enhancing technique to receive the signals, the at least one spectral efficiency enhancing technique allowing the at least one infrastructure equipment to receive the signals in the backhaul communications link.

This disclosure provides systems, methods, apparatus, and computer programs encoded on computer storage media, for relative timing drift correction for distributed multi-user transmissions. In one aspect, a first access point (AP) may receive a first signal from a second AP. The first signal may be associated with a channel sounding procedure to be performed substantially simultaneously by the second AP and the first AP. The first AP may then receive a second signal from the second AP, and prior to a substantially simultaneous transmission by the second AP and the first AP. The second signal may include timing information relative to the first signal. The first AP may determine a start time of the substantially simultaneous transmission at the first AP based on the timing information, and may initiate the substantially simultaneous transmission according to the determined start time.

Systems, methods, and computer-readable media herein dynamically adjust the number of elements active within a neighboring base station in order to reduce the back lobe overlap and thus reduce the interference caused by such an overlap. User devices assigned to communicate with an antenna array are monitored to determine if they are experiencing a decreased level of performance which may be caused by an overlapping back lobe from a neighboring cell site. If the user device's performance falls below a threshold value, the gain associated with the neighboring cell site is dynamically reduced in order to reduce the back lobe overlap.

A method, apparatus, and a computer-readable storage medium for a virtual multi-transmission reception point (TRP) or multi-panel transmission for ultra reliable low-latency communications (URLLC) are provided. In one example implementation, the method may include receiving, by a network node, at least two channel state information (CSI) reports from a user equipment (UE), the at least two CSI reports are received based at least on transmission and/or reception configuration transmitted to the UE and determining, by the network node, at least two beams for downlink transmission based on the at least two CSI reports. The method may further include transmitting, by the network node, a physical downlink control channel (PDCCH) to the UE, the PDCCH carrying scheduling information based on the at least two CSI reports and transmitting, by the network node, a physical downlink shared channel (PDSCH) to the UE, the PDSCH carrying at least two duplicate downlink data transmissions, each of the at least two duplicate downlink data transmissions is associated with one beam of the at least two beams.
