    • Techniques are disclosed for signaling retransmission-related information in a multi-carrier wireless communication system supporting three or more carriers. In an example method, a wireless transceiver forms a first ACK/NACK group by jointly coding ACK bits and NACK bits for a first subset of the carriers, and transmits the first ACK/NACK group during a first transmission slot allocated for the first ACK/NACK group. If no carriers of a second subset of the carriers are activated for the wireless transceiver, then the first ACK/NACK group is also transmitted during a second transmission slot that is otherwise allocated to ACK/NACK information for a second subset of the carriers. In another method, first and second ACK/NACK groups corresponding to first and second subsets of carriers are each formed from a codebook comprising a DTX codeword indicating that no data transmission for the mobile station was detected for the corresponding subset of carriers.

    • The present invention relates to methods and devices for use in multi carrier communication systems in which secondary downlink and secondary uplink carriers may be dynamically activated/deactivated by means of transmitting an HS-SCCH order from a radio base station to a user equipment. The HS-SCCH order is encoded by the radio base station according to an order mapping. The order mapping maps a desired activation status of a set of carriers to a corresponding encoded HS-SCCH order. The user equipment interprets the encoded HS-SCCH order to derive the desired activation status of the set of carriers. By using an appropriate order mapping, operations in the radio base station and/or the user equipment may be simplified, e.g. by allowing the radio base station to calculate the encoded HS-SCCH order based on the desired activation status.

    • Although described herein in terms of UE out-of-sync detection, those of skill in the art will readily recognize that embodiments of the present invention improve in-sync detection for currently out-of-sync UEs 22. That is, if an out-of-sync UE 22 detects sufficiently good channel conditions, it may announce this fact to the network and re-acquire in-sync status. For example, if the UE 22 receives F-DPCH signal transmissions and determines that, e.g., the TPC command error rate is less than a threshold, which is preferably much lower than 30%, over a measurement interval of, e.g., 240 slots (or 160 ms), the UE 22 may conclude that it is in-sync and announce this fact to the network 10. The restrictions of only valid F-DPCH transmissions during the UL DTX gated period will obviously enhance the reliability of this determination, just as is the case in determining out-of-sync status. Furthermore, according to at least one embodiment, the UE 22 may disregard the DTX UL DPCCH state, and transmit a scheduling request during a UL DTX gated period to announce to the network 10 its in-sync status.
    • 在具有不连续UL DPCCH传输的连续分组连接模式中,通过要求从基站到用户设备的所有F-DPCH传输在用户设备的有效期间是有效的,UTRAN用户设备的不同步和同步检测和下行链路功率控制得到改善 UL DTX门控时段。 此外,用户设备在UL DTX门控周期期间接收并考虑所有F-DPCH传输,用于功率控制,不同步和同步检测。 如果用户设备检测到不同步状态,则可以立即发送调度请求以通知网络,暂时或永久地取消不连续的UL DPCCH传输。

    • Channel estimation accuracy is improved by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a corresponding physical data channel allocated to the same receiver. The physical control channel may be a DPCCH, E-DPCCH or other type of physical control channel allocated to a receiver for facilitating uplink or downlink communication. In one embodiment, control channel symbols are transmitted for use in channel estimation by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a physical data channel allocated to the receiver (200). Control channel symbols are transmitted to the receiver over the physical control channel at the adjusted power level (202). The receiver uses the control channel symbols to perform channel estimation (204).
