摘要： A mobile device may establish a first wireless connection to a macro base station providing wide coverage in order to transmit control and/or broadcast channels, and may also establish a second wireless connection to a pico base station providing smaller coverage in order to transmit a high bandwidth data channel. These wireless connections may enable the mobile device to access a high speed channel within a picocell, while also maintaining continuous and reliable access to control and/or broadcast channels within a macrocell.

摘要： A wireless communication system and method schedules a beginning of an uplink transmission from a wireless device to a network transceiver with a first predetermined period of time after an end of a downlink transmission from the network transceiver device to the wireless device is scheduled. The uplink transmission and the downlink transmission comprise the same carrier frequency. The first predetermined period of time is related to a time required for the wireless device to switch from between receive and transmit modes. A beginning a downlink transmission from the network transceiver to the wireless device is scheduled with a second predetermined period of time after an end of an uplink transmission from the wireless device to the network transceiver is scheduled. The second predetermined period of time is related to a time required for the wireless device to switch between transmit and receive modes.

摘要： Techniques are disclosed that provide for femto base stations to become synchronized with other base stations in a wireless network. For instance, a macro base station may instruct a mobile station to engage in a synchronization operation that synchronizes one or more timings (e.g., OFDM timings) of a femto base station with one or more corresponding timings of the macro base station. This may involve the mobile station having timing references of the macro base station. Further, this may involve the mobile station performing scanning operations and/or handover ranging operations with the femto base station. The mobile device may determine timing offsets between the femto BS and the macro BS. These offsets may be sent to the macro base station or to the femto base station. Also, the femto base station may adopt timings employed by the mobile station. The macro base station or a femto base station may direct a femto base station to achieve synchronization either directly with timing adjustment offset, or with a list of already synchronized femto base station as synchronization reference.
