摘要： A method, system and device are provided for avoiding in-device coexistence interference between different radio technologies deployed in adjacent bands on the same device by controlling and separating the LTE signaling and the non-LTE signaling using dedicated time intervals to separate LTE signaling from non-LTE signaling. In addition, coexistence mode handover procedures are provided which use threshold-based triggering events to avoid coexistence interference and to prevent ping-pong effects by establishing a “keeping time” parameter so that a non-interfering network node does not switch back to an interfering network node after handoff. Coexistence interference is also avoided by providing a hybrid automatic repeat request (HARQ) mechanism which accounts for coexistence interference by providing a fixed or variable on-interval parameter and an activity parameter indicating whether non-LTE activity is present to maximize a time interval for non-LTE devices without interference from LTE activity on the same device.

摘要： A base station transmits control information to a mobile station. A first control channel is transmitted to the mobile station. The first control channel contains an indication of the number of control channel occurrences in a frame. A second control channel is transmitted to the mobile station in a control subframe. The second control channel contains information for communicating a packet between the base station and the mobile station. The control subframe is determined from the number of control channel occurrences in the frame. The packet can then be communicated between the base station and the mobile station in a subframe based on the control channels transmitted.

摘要： A system and method for synchronous spectrum sharing for a dedicated network in a wireless communication system based on orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) signaling is disclosed. The system and method includes detecting a frame of a broadcast waveform and extracting idle spectrum information from a subframe associated with the dedicated subchannel to the secondary user node. The system allows transmitting data from the secondary user node in unused symbol slots identified in the idle spectrum information thereby making efficient use of unused or idle spectrum. Accordingly, secondary users of the wireless communication system can dynamically form ad-hoc mesh network communications in fixed or mobile scenarios.

摘要： For use in a wireless network, a controller for relay stations. The relay station increases cell coverage and user data rates while employing power consumption saving techniques. The relay station compares a threshold power setting with a current power setting. If the threshold power setting is greater than the current power setting, the relay station increments the threshold power setting and decreases the cell coverage. If the threshold power setting is less than or equal to the current power setting, the relay station decreases the threshold power setting until the threshold power setting is equal to a total power setting of the relay station. The relay station also employs load balancing techniques by comparing a threshold power setting with a current load setting. If the threshold power setting is greater than the current load setting, the relay station increases the cell coverage based on the available bandwidth.
