    摘要: A first base station provides overlapping coverage area with second base stations and third base stations. Second base stations allow regular access to wireless devices and configure a second plurality of special subframes. Second base stations configure the same set of subframes as the second plurality of special subframes. Third base stations allow regular access to a restricted subset of wireless devices and configure a third plurality of special subframes. At least two base stations in the third base stations configure different set of subframes as the second plurality of special subframes.

    摘要: A wireless device receives messages comprising parameters of carriers and carrier groups. Downlink transmissions on a first carrier and at least one second carrier are substantially time aligned with each other. The wireless device receives time alignment commands comprising a time adjustment value and an index identifying a carrier group. Uplink transmissions on a first carrier group and a second carrier group employ different synchronization signals on different carriers as timing reference and are adjusted in response to different time alignment commands.

    摘要: Transmission timing of a random access preamble in an uplink carrier of a carrier group being determined employing a synchronization signal transmitted on a downlink carrier of the carrier group. The wireless device receives a time alignment command from the base station. The time alignment command comprises a time adjustment value and an index identifying the carrier group. The wireless device applies the time adjustment value to uplink signals transmitted on any activated uplink carriers in the carrier group.

    摘要: A base station transmits a message comprising configuration parameters of first radio resources of a control channel. The first radio resources comprise one or more sets of resource blocks in a subset of subframes in a plurality of subframes. The base station transmits scheduling information on the control channel for a packet transmitted on an uplink data channel. The base station transmits a positive or negative acknowledgement on second radio resources of a feedback channel for the received packet. The second radio resources start from the first OFDM symbol of a second subframe.

    摘要: A device transmits and/or receives voice packets on a first plurality of subcarriers. There is no guard band between any two subcarriers in the first plurality of subcarriers. The device transmits and/or receives a first subset of data packets on a second plurality of subcarriers and a second subset of the data packets on a third plurality of subcarriers. The following limitations may apply: a) there is no guard band between any two subcarriers in the second plurality of subcarriers, and b) there is at least a guard band between at least two subcarriers in the third plurality of subcarriers.
