    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.

    Abstract: Dynamic antenna switching based on weighted signal to noise ratio (SNR). A wireless device may include multiple antennas. SNR at each active antenna may be calculated. An antenna-specific weight may be applied to each antenna's SNR. The antenna-specific weights may further be radio specific and/or transmit or receive specific in some cases. Antenna selection (possibly just for a specific radio and/or for transmit or receive operations, depending on the specificity of the antenna weights), including potentially switching which antenna is used, may be based on the resulting weighted SNR values for each antenna. If the antenna-specific weights are radio specific and/or transmit or receive operation specific, the method may be performed multiple times with different antenna-specific weights to select antenna(s) for different radios and/or for other operations.
