Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first device and a second device may communicate over a communication link using a set of antenna elements. The first device may identify one or more antenna array reconfiguration trigger conditions and may correspondingly select a first subset of antenna elements for operation. The first device may transmit a message to the second device including an indication of the antenna array reconfiguration at the first device, a request for the second device to modify the second device's antenna array configuration, or both. The second device may receive the message and, based on the indication or the request, may modify its antenna array configuration. For example, the second device may select a second subset of antenna elements based on the selected first subset of antenna elements. The devices may communicate using their modified antenna array configurations.

Abstract: Methods, systems, and apparatuses are described for wireless communication using the mmW spectrum. In particular, antenna structures may include arrays of antenna elements to deal with line-of-sight issues. Further, antenna structures may be configured to produce a beam (e.g., signal) that is relatively narrow and has a relatively high gain to deal with losses, such as mentioned above. Still further, antenna structures may be configured to provide beam steering (e.g., beamforming) capability. Such antenna structures may be designed to be relatively compact to deal with the limited real estate available on modern wireless communication devices (e.g., cellular telephones).

Abstract: Methods, systems, and devices for wireless communications are described. A codebook adaptation may be performed for a flexible user equipment (UEs) to determine a codebook for a physical configuration of the UE. For example, if the UE determines that the physical configuration does not correspond to a pre-loaded codebook in its memory, the UE may provide information about the physical configuration to a base station to determine a corresponding codebook. Additionally, the UE may request that the base station provide channel information to assist with the codebook determination. In some cases, this request may indicate for the base station to allocate a specific number of channel state information reference signal symbols that the UE can use for the codebook determination. Additionally or alternatively, the UE may generate the codebook internally and then signal to the base station a request for a beam refinement procedure with the generated codebook.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support radio frequency (RF) component preferences in hybrid beamforming operations at millimeter Wave (mmWave) bands. In a first aspect, a method of wireless communication includes transmitting a capability message to a network entity including an identification of a constrained RF architecture of the UE, communicating an indication of a communication performance loss attributable to use of a non-preferred set of transmission states, and performing a communication with the network entity at the mmWave frequencies according to a transmission state selected by the network entity. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may communicate, using a first set of active antenna elements of an antenna array, during a first time period. The network node may activate a second set of active antenna elements based on a dynamic antenna set switching scheme, wherein the second set of active antenna elements includes at least one active antenna element not included in the first set, wherein a difference between a first main lobe property and a second main lobe property satisfies a main lobe threshold, and wherein a difference between a first side lobe property and a second side lobe property satisfies a side lobe threshold. The network node may communicate, using the second set of active antenna elements, during a second time period. Numerous other aspects are described.
