Abstract: The present invention provides methods for selecting a target cell for a blind handover. The methods may include selecting at least one target cell for a blind handover of a first mobile unit based on at least one measurement performed by the first mobile unit or at least one second mobile unit for at least one measurement-based handover.

Abstract: In a wireless telecommunications network, a Code Division Multiple Access scheme is applied to data to encode it. The CDMA encoded data may be time multiplexed with other data symbols. The time multiplexed data are then applied to Single Carrier-Frequency Division Multiple Access, SC-FDMA, transmissions. The CDMA scheme may be used for relatively small payloads, such as those associated with voice traffic and control signals, and the other data symbols are used for higher date rate transmissions. This enables autonomous transmission, without scheduling, for smaller payloads. A transmitter includes a selector (3) for performing time multiplexing in the uplink, the required transmission scheme being indicated by the Hybrid Automatic Repeat Request,HARQ, ID. A first branch (1) carries the other data symbols and a second branch (2) carries data to be transmitted as a CDMA scheme. A CAZAC code may be used in encoding the CDMA data.

Abstract translation: 在无线电信网络中，将码分多址方案应用于数据进行编码。 CDMA编码数据可以与其他数据符号进行时间复用。 然后将时间复用数据应用于单载波频分多址，SC-FDMA传输。 CDMA方案可以用于相对小的有效载荷，例如与语音业务和控制信号相关联的那些，并且其他数据符号用于较高的日期速率传输。 这使得能够进行自主传输，而无需调度，可以实现更小的有效载荷。 发射机包括用于在上行链路中执行时间复用的选择器（3），所需的传输方案由混合自动重传请求HARQ，ID指示。 第一分支（1）携带其他数据符号，第二分支（2）携带要作为CDMA方案发送的数据。 可以在编码CDMA数据时使用CAZAC码。
