Abstract: An apparatus in a wireless communication system is configured to perform a method for directional beam nulling of SRS-based data beams. A base station (BS) includes a transceiver and a processor. The processor is configured to transmit a data beam to at least one user equipment (UE). The processor is also configured to configure the data beam to have a null area in a direction of a satellite earth station (ES), the null area defining a space within a coverage area of the data beam in which a signal from the data beam is suppressed. The data beam is configured by: generating one or more steering vectors to the ES; obtaining a UE channel matrix via a sounding reference signal (SRS) and determining a rank value; and generating a beamforming precoder configured to directional null the data beam in the direction of the ES.

Abstract: Methods and apparatuses for enabling reuse, by a node in a basic service set (BSS), of a channel medium that is in use by devices of an overlapping BSS (OBSS) in a wireless local area network. A method of wireless communication performed by a first node includes the steps of obtaining, based on transmissions from other nodes in at least one of a BSS or an OBSS, network context information for a network environment around the first node, updating an OBSS packet detection (PD) threshold for spatial reuse (SR) based on the network context information, and performing, for a transmission to one of the other nodes in the BSS, an SR clear channel assessment (CCA) using the updated OBSS PD threshold for detection of packets transmitted by the nodes in the OBSS.

Abstract: Methods and apparatuses in a wireless communication system. A base station (BS) includes a transceiver and a processor. The processor is configured to transmit a common beam to at least one user equipment (UE). The processor is also configured to configure the common beam to have a null area in a direction of a satellite earth station, the null area defining a space within a coverage area of the common beam in which a signal from the common beam is suppressed.

Abstract: A system and method for user selection in distributed multiple-input, multiple-output (MIMO). The system performs a method that includes configuring a first channel state information-reference signal (CSI-RS) resource set for a serving transmission point (TRP) and a second CSI-RS resource for a concatenated channel, wherein the concatenated channel is between a virtual panel and the apparatus, the virtual panel comprising distributed panels from a serving TRP and a helping TRP. The method also includes computing a metric as a function of one or more quantities included in one or more measurement reports, received from a user equipment (UE), for the concatenated channel and at least one of the serving TRP channel or the helping TRP channel. The method also includes configuring, based on the metric, the UE for one of: a legacy transmission or a distributed MIMO transmission.

Abstract: A method for performing mobility load balancing includes receiving, at a server, current load data for a plurality of cells of a wireless communication network, selecting, from the plurality of cells, a target cell (s), wherein a value of the current load data for the target cell exceeds a first predefined threshold, and selecting, from a neighbor cell list corresponding to the target cell, a set of neighboring cells for the target cell. The method further includes calculating, a value of at least one utilization parameter for the target cell, determining, a CIO value and an E-tilt value for the target cell based on the value of the at least one utilization parameter for the target cell and configuring one or more physical layer parameters of the target cell based on the determined CIO and E-tilt values for the target cell.
