摘要： A method, in a network in which a handover of a wireless device occurs, the User Equipment (UE) moving from a source cell to a target cell, is provided. The method comprises at least: (at the source cell) determining a sequence number (SN) related to a data packet; forwarding at the RLC layer data packets to the target cell, the data packets being previously sent to the UE but unacknowledged by the UE and having SNs inferior to the determined sequence number; and sending the determined SN to the target cell. The method further comprises (at the target cell) sending a first data packet with the determined SN to the wireless device; the determined SN being a demarcation line for using different encryption keys. The UE will decrypt the received data packets having SNs inferior to the determined SN using an encryption key from the source cell; and decrypt received packets having SNs superior to the determined SN using an encryption key from the target cell.

摘要： The invention provides for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.
摘要翻译：本发明提供了无线资源的管理，其可以在合适的条件下使用分配给低优先级业务的资源来允许高优先级业务来减少呼叫阻塞。因此，高优先级服务可以通过低优先级业务来预先利用无线资源。这具有减少高优先级呼叫的呼叫阻塞的优点，同时允许低优先级呼叫比具有相同呼叫阻塞率的传统系统更多地接入无线电资源。因此，基站可以实现抢占机制，其将从活动的补充信道（SCH）突发收回沃尔什码和转发功率资源，以便适应输入的基本信道（FCH）请求。

摘要： A method and apparatus is provided for assigning resources for an acknowledgement channel, such as the PHICH in LTE systems. Acknowledgement channels for the mobile terminals are assigned to channel groups based on a predetermined assignment criteria. All acknowledgment channels in the same channel group receive acknowledgements on the same downlink resources (e.g., resource elements in OFDM system). A required transmit energy for each channel is determined. If the total required transmit energy for all channels exceeds an available transmit power, the allocated transmit energy for each channel is either scaled down so that the total actual transmit power for all acknowledgment channels is equal to the available transmit power, or some acknowledgment channels are not transmitted.

摘要： A method and apparatus is provided for assigning resources for an acknowledgement channel, such as the PHICH in LTE systems. A list of acknowledgement channels for a group of scheduled mobile terminals is generated. The list is sorted in descended order of the required transmit energies for the corresponding mobile terminals. The acknowledgement channels are then assigned to channel groups one at a time in sorted order to an available channel group with the lowest cumulative transmit energy. By sorting the channel list before assigning resources, the variance in the transmit energies for different channel groups is reduced. Given enough number of acknowledgement channel groups, the small variance in the transmit energies for different channel groups implies improved error rate performance.

摘要： Methods and apparatus for performing finger de-spreading and MRC combining are provided. A large antenna buffer is used to buffer all the finger signals of the same user so that the receiver can do both de-spreading and MRC at the same time without buffering the de-spreading finger symbols. For each user, a reference time is introduced to align all the finger signals of the same user in the Antenna Buffer. The reference time delay is used to generate the PN codes for de-spreading, as well as to count the number of symbols in a PCG or a frame. Methods for antenna buffer arrangement, interpolating filter implementation, channel estimation and MRC for traffic data channels, timing for the user's finger signal de-spreading and MRC, long code and short code generation for de-spreading, new finger allocation and finger timing adjustment.

摘要： A cellular wireless communication system includes base transceiver stations and mobile stations that operate with a closed loop power control. The mobile tracking is performed based on the lock in and lock out thresholds by the base transceiver stations. A forward link power control bit is decoded from the reverse channel. An additional threshold is introduced for determining at the base transceiver station whether the decoded forward link power control bit is valid or invalid. The finger energies obtained from a finger processor formed by a RAKE receiver of the base transceiver station are compared to the additional validation threshold. The additional validation threshold is independent of the tracking thresholds and usually greater than them. The validation performance may not be affected by low signal/noise. The forward link traffic channel gain of the base transceiver station is controlled in response to the invalidity of the decoded forward power control bit. The decoding of the reverse link power control bit and the validity determination of the decoded reverse link power control bit are performed by similar methods to those of the forward link power control bit. With improved validation methods, the forward link and reverse link transmission power is more accurately controlled.
