    • A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network is obtained using an orthogonal covering sequence and a second sequence. Embodiments of the present invention mitigate interference by calculating a first orthogonal covering (OC) index and a second OC index from an indicator received from a serving base station (NodeB). A first index n1 is derived and a second index n2 is derived using the first index n1. A first orthogonal covering (OC) index and a first cyclic shift (CS) is determined using the derived index n1. A second OC and a second CS is derived using the derived index n2. A first slot of a subframe is generated using the OC indexed by the first OC index and the first CS and a second slot of the subframe is generated using the OC indexed by the second OC index and the second CS.
    • 信息从次级到主节点的传输发生在多个N个逻辑时间段内。 使用正交覆盖序列和第二序列获得在无线网络中从次级到主节点的传输。 本发明的实施例通过从从服务基站(NodeB)接收的指示符计算第一正交覆盖(OC)索引和第二OC索引来减轻干扰。 导出第一索引n1,并且使用第一索引n1导出第二索引n2。 使用导出的索引n1来确定第一正交覆盖(OC)索引和第一循环移位(CS)。 使用导出的索引n2导出第二个OC和第二个CS。 使用由第一OC索引索引的OC和第一CS生成子帧的第一时隙,并且使用由第二OC索引和第二CS索引的OC来生成子帧的第二时隙。

    • A method for multiplexing reference signal (RS) transmissions from user equipments (UEs), with the RS having a bandwidth larger than the data signal bandwidth (distributed RS) is provided. A transmission time interval (TTI) comprises of one or more sub-frames and each sub-frame comprises of at least two RS transmission periods and a plurality of data signal transmission periods. A distributed RS is transmitted during at least one of the at least two RS transmission periods in at least one of the sub-frames comprising the TTI. During the remaining RS transmission periods, for a UE having a data signal transmission, the RS bandwidth is substantially the same as the data signal bandwidth (localized RS). The total system bandwidth is divided into contiguous, non-overlapping sub-bandwidths, called reference signal multiplexing blocks (RSMBs). Transmission of distributed RS occurs within an RSMB and does not cross over different RSMBs. The size and number of RSMBs can be re-configurable in time and a re-configuration period is much larger than the TTI duration.

    • UE-initiated accesses within a cellular network are optimized to account for Doppler shift. A user equipment (UE) receives information that designates a particular access slot as high-speed and designates another access slot as low-speed within a given cell. The UE determines its relative speed to a serving base station (NodeB) within the cell. The UE selects either a baseline structure or an alternate structure if the relative speed is less than a threshold value or only an alternate structure if the relative speed exceeds the threshold value. The UE transmits a signal to the NodeB using the selected structure, such that the baseline structure is transmitted only in the designated low-speed access slot and that the alternate structure is transmitted only in the designated high-speed request slot.
    • UE发起的蜂窝网络中的接入被优化以考虑多普勒频移。 用户设备(UE)以特定小区的速度接收指定特定接入时隙的信息,并指定另一接入时隙为低速。 UE确定其与小区内的服务基站(NodeB)的相对速度。 如果相对速度小于阈值,则UE选择基线结构或替代结构,或者如果相对速度超过阈值,则UE选择替代结构。 UE使用所选择的结构向NodeB发送信号,使得仅在指定的低速接入时隙中发送基线结构,并且仅在指定的高速请求时隙中发送替代结构。
