Abstract: A circuit includes a first wireless interface circuit that transceives packetized data between a host module and a first external device in accordance with a first wireless communication protocol, wherein the first wireless protocol carries wireless telephony data for communication with a wireless telephony network. A second wireless interface circuit transceives packetized data between the host module and a second external device in accordance with a second wireless communication protocol. The second wireless interface circuit includes at least one module that is shared with first wireless interface circuit. The first wireless interface circuit and the second wireless interface circuit operate in accordance with a wireless interface schedule that includes a first time interval where the first wireless interface device and the second wireless interface device contemporaneously use the at least one module.

Abstract: Aspects of a method and system for wireless local area network (WLAN) phase shifter training are presented. Aspect of the system may enable a receiving station, at which is located a plurality of receiving antennas, to estimate the relative phase at which each of the receiving antennas receives signals from a transmitting station. This process may be referred to as phase shifter training. After determining the relative phase for each of the receiving antennas, the receiving station may process received signals by phase shifting the signals received via each of the receiving antennas in accordance with the relative phase shifts determined during the phase shifter training process. Signals received via a selected one of the receiving antennas may be unshifted. The processed signals may be combined to generate a diversity reception signal.

Abstract translation: 提出了无线局域网（WLAN）移相器训练方法和系统的方面。 系统的方面可以使位于多个接收天线的接收站估计每个接收天线从发射台接收信号的相对相位。 该过程可以被称为移相器训练。 在确定每个接收天线的相对相位之后，接收站可以通过根据在移相器训练过程中确定的相对相位移位通过每个接收天线接收的信号来处理接收信号。 经由选择的一个接收天线接收到的信号可以是非移相的。 经处理的信号可以被组合以产生分集接收信号。

Abstract: Various methods and systems are provided for time domain coexistence of RF signals. In one example, among others, a method includes obtaining access to a WLAN channel during a free period of a coexisting cellular connection, providing a RDG to allow another device to transmit for a duration corresponding to at least a portion of a TXOP, and receiving a transmission during the duration. In another example, a method includes obtaining access to a WLAN channel during a transmission period of a coexisting cellular connection and providing a protection frame to defer transmissions from another device for a duration corresponding to at least a portion of a TXOP. In another example, a method includes determining a shift of a BT transaction based at least in part upon a schedule of cellular communications and shifting at least a portion of the BT transaction based upon the determined shift.
