摘要： The present invention provides a method for mitigating outages in wireless communication systems using feedback for control channels formed by aggregating groups of resource blocks or resource elements, the method. One embodiment of the method includes generating control channel feedback at user equipment. The control channel feedback is generated using one or more measurements performed on signals received at the user equipment over a downlink control channel at a current aggregation level. The method also includes transmitting the control channel feedback over an uplink channel and using this information for the optimal implementation of Cell range expansion by the network.

摘要： Embodiments of the claimed subject matter provide a method and apparatus for virtual sectorization using an active antenna array. Embodiments of the apparatus include a transmitter for providing signals to an active antenna array. The signals cause the active antenna array to transmit a first reference signal to a first sector indicated to user equipment within the first sector by a sector identifier. The signals also cause the active antenna array to transmit a plurality of second reference signals into a corresponding plurality of second virtual sectors that overlap the first sector. The apparatus also includes a scheduler for scheduling transmission to user equipment based on feedback generated by the user equipment using the first reference signal or the second reference signals.

摘要： A method may include determining a metric for at least one physical resource block of a wireless cellular network in at least a one cell. Each physical resource block may include a set of frequencies, and/or the metric may be based on interference on the at least one physical resource block in the at least one cell. A determination of whether the metric violates a metric threshold may be made, and an overload indicator may be sent to at least one other cell if the metric violates the metric threshold.

摘要： In a wireless telecommunications network, a Code Division Multiple Access (CDMA) scheme is applied to data to encode it. The encoded data transmitted in the uplink using an Orthogonal Frequency Division Multiplexing (OFDM) frame structure including a cyclic prefix (CP). The CDMA encoded data may be time multiplexed with Single Carrier-Frequency Division Multiple Access (SC-FDMA) transmissions. The CDMA transmissions may be used for relatively small payloads, such as those associated with voice traffic and control signals, and the SC-FDMA transmissions 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 mode being indicated by the Hybrid Automatic Repeat Request (HARQ) ID. A first branch 1 carries SC-FDMA data 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.
摘要翻译： 在无线电信网络中，将码分多址（CDMA）方案应用于数据进行编码。 使用包括循环前缀（CP）的正交频分复用（OFDM）帧结构在上行链路中发送的编码数据。 CDMA编码数据可以与单载波频分多址（SC-FDMA）传输进行时间复用。 CDMA传输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，以及用于较高日期传输的SC-FDMA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，所需模式由混合自动重传请求（HARQ）ID指示。 第一分支1携带SC-FDMA数据，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。
