Abstract: Aspects of the present disclosure describe configuring a number of antennas in an antenna array to use in communicating in a wireless network. The number of antennas of the antenna array, less than all available antennas for transmission or reception in the antenna array, can be determined such to achieve a radio frequency (RF) power that results in a certain effective data rate for communicating in the wireless network. The number of antennas can be indicated, over a backhaul, to one or more other access points of the wireless network to coordinate using of the number of antennas at a determined time. One or more devices in the wireless network can be communicated with using the number of antennas.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a user equipment (UE) communicates with a base station on different uplink (UL) and downlink (DL) beam paths. In the example, the UE may indicate to the base station a preferred beam path to use. The UE may indicate the preferred beam path in response to an explicit request from the base station or without an explicit request. The use of different UL/DL beam paths allow beam paths which avoid interference from a user of the UE to be used.

Abstract: A beam selection method and apparatus suitable for millimeter wave (mmW) communication systems is disclosed. In one aspect, a user equipment (UE) may perform a beam sweep procedure to identify suitable downlink beams candidates from one or more gNBs. The UE may generate a beam list by selecting some of the downlink beams for active tracking. When beams on the beam list become unavailable, the UE may compare the number of available beams on the beam list with a threshold value. If the number of available beams falls below the threshold, the UE may perform another beam sweep procedure.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine at least one phase estimate for at least one beam received by the user equipment during a beam training or channel estimation procedure; and/or provide the at least one phase estimate to a base station from which the at least one beam is received for the base station to reconstruct an estimated channel matrix of the user equipment. In some aspects, a base station may receive feedback information from a UE identifying phase estimates for a plurality of beams transmitted to the UE, wherein the feedback information relates to a selected beam for the UE and one or more other beams of the plurality of beams; and/or determine an estimated channel matrix for the UE based at least in part on the feedback information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may determine, when in communication with a plurality of other wireless nodes via a plurality of links of a network, a plurality of transmit powers for the plurality of links, wherein the plurality of transmit powers are selected to control inter-link interference or to satisfy a maximum transmit power criterion. The wireless node may transmit, using the plurality of transmit powers for the plurality of links, information, to the plurality of other wireless nodes, concurrently, based at least in part on determining the plurality of transmit powers for the plurality of links. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated transmissions in certain systems, such as millimeter wave (mmW) systems. A method of wireless communication by a user equipment (UE) generally includes providing an indication to a plurality of base stations (BSs) of one or more selected beams for transmission by each of the plurality of BSs. The method includes determining one or more co-phase factors. The method includes receiving a coordinated transmission from the plurality of BSs based on the one or more selected beams and the one or more co-phase factors. A method by a BS generally includes receiving the indication from the UE of the one or more selected beam, determining one or more co-phase correction factors, and sending a coordinated transmission to the UE based, at least in part, on the one or more selected beam and the one or more co-phase correction factors.
