Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of transmission instances which are logical time durations. A secondary node receives an allocation of periodic transmission instances for a scheduling request indicator (SRI) and an allocation if periodic transmission instances for a sounding reference signal (SRS). In a particular transmission instance allocated for the transmission of both SRS and SRI, the secondary node transmits the SRI without transmitting the SRS if the SRI indicates a pending scheduling request; otherwise, the secondary node transmits the SRS without transmitting the SRI.

Abstract: User equipment (UE)—initiated accesses within a cellular network are optimized to account for cell size and to reduce signaling overhead. A fixed set of preamble parameter configurations for use across a complete range of cell sizes within the cellular network is established and stored within each UE. A UE located in a given cell receives a configuration number transmitted from a nodeB serving the cell, the configuration number being indicative of a size of the cell. The UE selects a preamble parameter configuration from the fixed set of preamble parameter configurations in response to the received configuration number and then transmits a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.

Abstract: Wireless communication between a base station and at least one user equipment comprises the following. Each user equipment periodically measures channel quality of communication with the base station and transmits a channel quality indicator to the base station. The base station schedules communication with the at least one user equipment based upon the periodically transmitted channel quality indicators.

Abstract: A wireless device includes a preamble detector configured to identify a plurality of preambles transmitted via a random access channel of a wireless network. The preamble detector includes a noise floor estimator. The noise floor estimator is configured to: estimate, for a given preamble root sequence identified by the preamble detector, a noise floor value as mean energy of received signal samples, excluding detected preamble samples on the give preamble root sequence, below a noise floor threshold assigned to the given preamble root sequence. The noise floor estimator is configured to compute the noise floor threshold as a product of: average energy of the received signal samples less total signal energy contained in each cyclic prefix window in which a preamble is detected using the given preamble root sequence; and a predetermined normalized relative noise floor threshold based on a target false preamble detection rate.

Abstract: A detailed design of an LTE Link Adaptation function for LTE uplink is disclosed. A new approach for adapting SINR backoff in OLLA is used when serving non-time-sensitive radio bearers without target BLER constraint. A sub-optimal scheduler is also disclosed wherein the SINR measurements at the ILLA input are updated on each TTI for the UEs scheduled in that sub-frame for future UL transmission with a fresher interference measurement from the sub-frame preceding by 8 ms the actual transmission sub-frame. This allows for exploitation of a correlation peak of the interference resulting from HARQ retransmissions. A schedule incorporating these features improves upon, with a minor complexity increase, the spectral efficiency performance of a low-complexity baseline scheduler only based on SINR updates at SRS rate.
Abstract translation: 公开了用于LTE上行链路的LTE链路适配功能的详细设计。 在不使用目标BLER约束的情况下服务非时间敏感的无线电承载时，将使用适用于OLLA中SINR退避的新方法。 还公开了一种次优调度器，其中在ILLAN输入处的SINR测量在针对在该子帧中调度的UE的每个TTI上被更新以用于未来的UL传输，其中来自前一个子帧的更新的干扰测量在8ms之前，实际 传输子帧。 这允许利用由HARQ重传产生的干扰的相关峰值。 仅基于SRS速率下的SINR更新，结合了这些特征的调度改进了低复杂度基线调度器的频谱效率性能，同时增加了较小的复杂度。

Abstract: User equipment (UE)-initiated accesses within a cellular network are optimized to account for cell size and to reduce signaling overhead. A fixed set of preamble parameter configurations for use across a complete range of cell sizes within the cellular network is established and stored within each UE. A UE located in a given cell receives a configuration number transmitted from a nodeB serving the cell, the configuration number being indicative of a size of the cell. The UE selects a preamble parameter configuration from the fixed set of preamble parameter configurations in response to the received configuration number and then transmits a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.
