    摘要： TDD devices may transmit using multiple antennas. First and second antennas having first and second receive conditions may receive a communication. In an aspect, first and second transmit conditions for the first and second antennas may be determined based on the first and second receive conditions. In an aspect, the first and second transmit conditions may be compared to select the first or second antenna for transmissions. In an aspect, the first and second receive conditions may be compared to select the first or second antenna for transmissions. In an aspect, first and second transmission conditioning values, which may determine transmission powers, may be determined based on the first and second receive conditions. A first transmission chain, associated with an active RAT or carrier, and a second transmission chain, associated with an inactive RAT or carrier, may be activated to send transmissions from the first and second antennas.

    摘要： A wireless device includes: a first radio and first transceiver configured to transmit and receive according to a first radio access technology; a second radio and second transceiver configured to transmit and receive according to a second radio access technology; a first antenna and a second antenna connected to the first radio and the second radio; a switch; and a control unit configured to control the switch to configure connections of the first and second antennas to the first and second radios. The control unit is configured to control the switch to disconnect the second radio from the second antenna in response to a receiving, by the second radio through the second antenna, a signal that is below a predetermined threshold, and to connect the second radio to the first antenna during a wakeup period of the second radio.

    摘要： This disclosure provides systems, methods, and apparatus for an initial network acquisition process via multiple antennas. In one aspect a method of establishing communications via a wireless network at a wireless communications apparatus is provided. The method includes attempting an initial acquisition process, over one or more frequencies, for establishing communications over the wireless network via a transmit circuit and a receive circuit transmitting and receiving via a first antenna. The method further includes switching the transmit circuit and the receive circuit from transmitting and receiving via the first antenna to a second antenna in response to detecting failure of the initial acquisition process. The switching is independent of a performance metric of the first or the second antenna. The method further includes re-attempting the initial acquisition process based on the switching to the second antenna over the one or more frequencies.

    摘要： This disclosure provides techniques for managing antenna sharing on a multi-mode wireless device between coexisting cellular and WLAN modems operating on the same band. One of the modems can communicate a WLAN scanning parameter to another one of the modems, and the distribution of shared antennas between the cellular modem and the WLAN modem may be modified based at least in part on the communicated scanning parameter to accommodate a WLAN scan on channels in the shared band. The distribution of the shared antennas between the modems for the WLAN scan may additionally or alternatively be selected based at least in part on the source of a detected WLAN scanning trigger (e.g., whether the scan is triggered by an application of the wireless device or the WLAN modem of the wireless device).
