Methods, systems, and devices for wireless communications are described. A transmitting device, which may be an example of a user equipment and/or a base station, may receive a signal from a receiving device indicating an antenna topology supported by the receiving device. The transmitting device may select, based at least in part on the antenna topology, a diversity scheme for performing a wireless transmission to the receiving device, the diversity scheme including one or more diversity types from a plurality of diversity types. The transmitting device may transmit the wireless transmission to the receiving device employing the selected diversity scheme.

A technique for improving wireless communication characteristics involving matching transmitter antenna patterns to receiver antenna patterns. In a specific implementation, the transmitter antenna pattern adapts to changing parameters, such as when a smartphone is initially held in a first orientation and is later held in a second orientation. Because the transmitter antenna pattern matches receiver antenna patterns, signal quality between stations improves. In some implementations, antennas are organized and mounted to maximize spatial diversity to cause peak gains in different directions.

A vehicle communications system includes a pair of antennas, a radio, and a controller. The controller is configured to enable and disable antenna diversity between communication over a safety channel and communication over a service channel.

A system for managing control of signal penetration into a building includes an exterior RF transmission unit located on an outside of the building, for transceiving signals at a first frequency that experiences losses when penetrating a structure of the building on a first RF communications link from an exterior base station and converting between the received signals at the first frequency and second signals in a first format that overcome losses caused by penetrating the structure of the building over a wireless communications link. An interior RF transmission unit located on the interior of the building and communicatively linked with the exterior RF transmission unit via the wireless communications link, receives and transmits the converted second signals in the first format that counteracts the losses caused by penetrating the structure of the building. A management control system configures operating parameters of the exterior RF transmission unit and the interior RF transmission unit within a system configuration controller. At least one interface enables user access to the management control system.

This disclosure provides systems, methods, and apparatuses for wireless communication. In some aspects, a user equipment (UE) may enable adaptive receive diversity (RxD) by receiving an indicator for a channel occupancy time (COT), outside of the COT and in a non-RxD mode, and may transfer to the RxD mode for reception during the COT. After an end to the COT, the UE may return to the non-RxD mode. In this way, the UE enables improved power gain, diversity gain, or spatial nulling gain during a COT, and enables reduced power utilization outside of the COT.

A communication apparatus capable of wireless communication with another communication apparatus via a first communication path and a second communication path sets a directivity of an antenna to a first directivity capable of wireless communication via the first communication path and receives data from the another communication apparatus via the first communication path. When the communication apparatus sends an acknowledgement signal to the another communication apparatus via the first communication path in response to reception of the data, the communication apparatus sets the directivity of the antenna to a second directivity capable of wireless communication via the first communication path and wireless communication via the second communication path for a set period thereafter.
