摘要:
A wireless device at least demodulates, descrambles and decodes a first control signal to generate a first signal. The wireless device processes the first signal by at least encoding, scrambling, modulating and scaling the first signal. The wireless device subtracts the processed first signal from received signals to generate a second signal. The wireless device at least demodulates, descrambles and decodes the second signal to generate a second control message.

A base station configured to communicate over a plurality of carriers. The plurality of carriers comprise at least one backward compatible carrier and at least one non-backward compatible carrier. The base station transmits a control message to a wireless device. The control message comprises an identifier for a carrier and information identifying a carrier type. The carrier type is either a backward compatible type or a non-backward compatible type. The base station configured to transmit a plurality of packets to a wireless device on non-backward compatible carrier(s) and backward compatible carrier(s).

A wireless device receives a message assigning each second carrier to one of a first carrier group and second carrier group(s). The message comprises parameters for each second carrier. If the parameters comprise a carrier group index for a second carrier, the second carrier is assigned to one of the second carrier group(s) identified by the carrier group index. Otherwise, the second carrier is assigned to the first carrier group. The wireless device receives a time alignment command comprising the carrier group index and a time adjustment value.
摘要:
A base station transmits first scheduling information on a first control channel for a first packet communicated with a first wireless device. First radio resources of the first control channel start from the first OFDM symbol of each subframe. The base station transmits a radio resource control (RRC) message causing configuration of second radio resources of a second control channel in a second wireless device. The second radio resources comprise resource blocks in a subset of subframes. The base station transmits second scheduling information on the second control channel for a second packet communicated with the second wireless device.
摘要:
A base station transmits a first message comprising a field describing content over a first plurality of subcarriers. The base station receives a second message requesting for the content. The base station transmits a first plurality of content packets to the wireless device over a second plurality of subcarriers of a first carrier. The first plurality of packets comprises a first portion of the content. The base station transmits a second plurality of packets to the wireless device over the first carrier and at least one additional carrier over a third plurality of subcarriers.
摘要:
A base station configures a first carrier group and a second carrier group in a wireless device. The wireless device transmits first uplink signals in the second carrier group employing a first secondary carrier in the second carrier group as a timing reference carrier. The wireless device autonomously changes the timing reference carrier to a second secondary carrier in the second carrier group. The second secondary carrier is an active carrier different from the first secondary carrier. The wireless device transmits second uplink signals in the second carrier group employing the second secondary carrier as the timing reference carrier.
摘要:
A base station transmits on a first control channel first scheduling information for a control message. First radio resources of the first control channel start from the first symbol of each subframe in a plurality of subframes. The base station transmits the control message configuring second radio resources of a second control channel. The second radio resources comprise resource blocks in a subset of subframes in the plurality of subframes. The control message indicates the subset of subframes and a starting symbol of the second control channel. The base station transmits second scheduling information on the second control channel.
摘要:
A base station transmits a message assigning each secondary cell to a cell group. The message comprises dedicated parameters for a secondary cell. If the dedicated parameters comprise a cell group index for the secondary cell, the secondary cell is assigned to a secondary cell group. Otherwise, the secondary cell is assigned to the primary cell group. The message comprises MAC dedicated parameters comprising a sequence of at least one information element. Each information element comprises a first cell group index of a first secondary cell group and a corresponding time alignment timer value.

摘要:
A base station receives first uplink data packets on a first uplink data channel of a first uplink carrier. A first portion of bandwidth of the first uplink carrier is employed for the first uplink data channel and a second portion is employed for a first uplink control channel. The base station receives second uplink data packets on a second uplink data channel of a second uplink carrier. The entire active bandwidth of the second uplink carrier is employed for the second uplink data channel. The base station transmits positive/negative acknowledgements for the first and second uplink data packets.
