摘要： A cell within cellular network includes user equipments (UEs) that transmit data to a base station (eNB). Over a period of time, not all of the UEs will have data to transmit. The UEs are tracked as a scheduled portion and an unscheduled portion, wherein a UE is included in the scheduled portion in response to receiving a scheduling request from the UE. Synchronization is maintained between the eNB and each UE in the scheduled portion by sending a timing adjustment (TA) command if needed. Synchronization is maintained between the eNB and each UE in the unscheduled portion by allocating a periodic reference signal (sync-RS) to each UE in the unscheduled portion and by sending a respective timing adjustment (TA) command if needed to each respective UE in the unscheduled portion in response to a respective sync-RS received from each UE in the unscheduled portion.

摘要： A cell within cellular network includes user equipments (UEs) that transmit data to a base station (eNB). UEs are synchronized to the eNB upon entry to the cell. If a particular UE has data to transmit, it will be placed in a connected state and scheduled for transmission. Over a period of time, not all of the UEs will have data to transmit. The UEs are tracked as a scheduled portion and an unscheduled portion, wherein a UE is included in the scheduled portion in response to receiving a scheduling request from the UE. Synchronization is maintained between the eNB and each UE in the scheduled portion by sending a timing adjustment (TA) command if needed in response to receiving a scheduled transmission from each respective UE in the scheduled portion; Synchronization is maintained between the eNB and each UE in the unscheduled portion by allocating a periodic reference signal (sync-RS) to each UE in the unscheduled portion and by sending a respective timing adjustment (TA) command if needed to each respective UE in the unscheduled portion in response to a respective sync-RS received from each UE in the unscheduled portion.

摘要： 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.
摘要翻译： 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。

摘要： 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 a first and a second sequence. Embodiments of the present invention mitigate interference by restricting the choice of the first sequence. Thus, in an embodiment of the invention, the first sequence is selected from a set of M sequences wherein M is strictly less than N. In order to accommodate high-velocity users, the restricted set contains a pair of sequences whose element-wise product is mirror symmetric. In other embodiments of the invention, the choices of the first sequence and second sequence in a time-frequency resource is arranged such that interference is mitigated. A transmission component for K-th logical time duration is obtained from the entire second sequence and K-th element of the first sequence.

摘要： A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell. The specific SRI subframe offset and the index value enable the UE to determine a unique combination of cyclic shift, RS orthogonal cover, data orthogonal cover, and resource block number for the UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH).
