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 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.

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).

摘要： This invention is a method for extending the coverage and/or improving the capacity of wireless communication networks comprising inserting a Relay Node (RN) in the Radio Access Network (RAN). The relay node relays the signal between the Base Station node (eNB) and the User Equipment (UE). The relay node is wirelessly connected to the base station. The base station uses the same radio access technology (RAT) for the base station to user equipment link and the base station to relay node link. The relay node uses the same radio access technology for the base station to relay node link and the relay node to user equipment link. The relay node is non-transparent and seen as base station by the user equipment.

摘要： User equipment (UE)-initiated accesses within a cellular network include non-synchronized random access requests when the UE is not synchronized with a base station that is serving a cell occupied by the UE. The random access request is formed by generating a set of samples at a selected sample rate, such that the set of samples spans a specified duration period, wherein the sample rate is one of a plurality of different sample rates enabling different implementations of the random access transmission. The specified duration period is integrally divisible by each of the plurality of different sample periods.

摘要： A transport block size (TBS) of a first uplink message (RACH Msg3) transmitted on a Physical Uplink Shared Channel (PUSCH) during a random access procedure in a User Equipment (UE) accessing a radio access network may be determined by receiving a pathloss threshold parameter. A downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE is then determined. A smaller value of TBS is selected from a set of TBS values if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter. A larger value of TBS is selected if the pathloss value is less than the operating power level of the UE minus the pathloss threshold parameter and the TBS required to transmit the RACH Msg3 exceeds the smaller TBS value.
摘要翻译：在访问无线电接入网络的用户设备（UE）中的随机接入过程期间在物理上行链路共享信道（PUSCH）上发送的第一上行链路消息（RACH Msg3）的传输块大小（TBS）可以通过接收路径损耗来确定阈值参数。然后确定表示UE和服务于UE的基站（eNB）之间的无线电链路状况的下行链路路径损耗值。如果确定的路径损耗值大于UE的工作功率级别减去路径损耗阈值参数，则从一组TBS值中选择较小的TBS值。如果路径损耗值小于UE的工作功率级别减去路径损耗阈值参数，并且发送RACH Msg3所需的TBS超过较小的TBS值，则选择较大的TBS值。

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。
