Abstract: A device and method selects an antenna configuration. The method performed at a user equipment includes determining at least one communication functionality that is being used, each communication functionality configured to utilize at least one antenna in a multi-antenna arrangement of the user equipment. The method includes receiving a first indication of whether a cellular communication functionality is being used, the cellular communication functionality configured to utilize at least one antenna in the multi-antenna arrangement. The method includes receiving a second indication of whether a coexistence condition is present. The method includes determining an antenna configuration for the multi-antenna arrangement to be used by the determined communication functionality based upon the determined communication functionality, the first indication, and the second indication. The method includes configuring the multi-antenna arrangement for the determined communication functionality based upon the antenna configuration.

Abstract: Apparatus and methods for performing simultaneous time division duplex (TDD) communications are disclosed. A wireless communication device can be configured to establish both a first TDD communication link and a second TDD communication link with a network, such as a telecommunication network. Thereafter, the wireless communication device can send TDD uplink data to the network via the first TDD communication link, and receive TDD downlink data from the network via the second TDD communication link, such that a portion of the TDD uplink data is sent to the network at the same time a portion of the TDD downlink data is received from the network. In this manner, the transmissions of TDD uplink data and the TDD downlink data can occur simultaneously, via multiple communication links. Further, the TDD downlink data can be received in multiple, coordinated data transmissions using Long Term Evolution (LTE) multiple-input and multiple-output (MIMO) antenna diversity.
