In a multiuser (MU) multiple antenna system (MAS), a central processing unit is communicatively coupled to multiple distributed wireless terminals (WTs) via a network. The central processing unit processes channel measurements indicative of channel conditions between the multiple distributed WTs and a plurality of user devices and selects a plurality of WTs from the multiple distributed WTs to enhance channel space diversity within the MU-MAS. The central processing unit calculates (Multiple Input, Multiple Output) MIMO weights from the channel measurements for precoding a plurality of data streams that are transmitted concurrently from the plurality of WTs to the plurality of users, wherein the MIMO weights provide for a plurality of independent MIMO channels.

Wireless communication devices (UEs) may include multiple receive (RX) chains and associated antennas, and at least one transmit (TX) chain co-located with one of the RX chains. The UE may track instant fading of the antenna gain(s) during reception of packets from an associated access point (AP) device to which the UE intends to transmit packets. The UE may also track long term antenna gain(s), using any packets received at the multiple RX chains within the UE. At a switching occasion, a decision is made by the UE whether to switch antennas. If the instant fading detection is based on packets received no later than a specified time period prior to the switching occasion, then the UE may make the switching decision based on the results of the instant fading tracking. Otherwise, the UE may make the switching decision based on the results of the long term antenna gain tracking.

A switching device is adapted for a true diversity receiver and contains: a control switch defined between two microcontrollers of two antennas and configured to switch RF wireless microphone signals so that the two microcontrollers execute a single-receiving dual true diversity program or a dual-receiving single true diversity program. The RF wireless microphone signals are received by the two antennas and are decoded to sound signals by two digital decoders respectively, and the sound signals are sent to two audio signal processors by a multiplexer which corresponds to the two microcontrollers to switch the sound signals of a single-receiving dual true diversity or a dual-receiving single true diversity. Thereafter, the sound signals are output by a sound signal mixer.

A wireless communication device may receive with one of N antennas a signal processing message indicating a number up to N signals to process. Each of the N antennas may used to receive a communication. The indicated number of up to N signals may be processed and data from the indicated number of up to N signals recovered.

An apparatus may operate in a dual connectivity mode in which the apparatus is simultaneously connected to carriers of different radio access technologies. The apparatus may operate via a first antenna set of a plurality of antenna sets, the first antenna set including a first communication path. The apparatus may determine to operate via a second antenna set of the plurality of antenna sets based on whether one or more criteria is satisfied. The apparatus may select at least one second communication path for the second antenna set based on the one or more criteria. The apparatus may operate via the second antenna set over the at least one second communication path when the criteria is satisfied.

In one embodiment, a system for allocating clients between radios of an access point is disclosed.

A base station is disclosed that includes two separated antenna arrays. In a TDD mode of operation, both arrays are used for either transmit or receive. In a sub-band full-duplex mode of operation, one array is used to transmit downlink symbols while the remaining array is used to receive uplink symbols.

This disclosure provides methods, devices and systems for channel sounding for wireless communications. Some implementations more specifically relate to scheduling sounding reference signal (SRS) resource sets for wireless devices having more than 4 receive (RX) antenna ports. In some implementations, a base station may determine an antenna switching capability of a user equipment (UE). The antenna switching capability indicates a number of RX antenna ports of the UE. The base station schedules a number of SRS resource sets for the UE based at least in part on the number of RX antenna ports in excess of four. For example, the number of RX antenna ports may be equal to 8. As another example, the number of RX antenna ports may be equal to 6. The base station further receives, from the UE, uplink transmissions of one or more SRS resources for each of the scheduled SRS resource sets.
