摘要： PROBLEM TO BE SOLVED: To allow a receiving entity to derive a longer channel estimate while limiting overhead.
SOLUTION: A transmitting entity transmits a pilot on different groups of subbands at different time intervals. N subbands in a system are arranged into M non-overlapping groups. The transmitting entity transmits the pilot on a different subband group in each time interval, and selects all M subband groups at M time intervals based on a pilot staggering pattern. A receiving entity derives an initial impulse response estimate with P channel taps based on the pilot received on one subband group and two longer impulse response estimates with different lengths used for data detection and time tracking.

摘要： PROBLEM TO BE SOLVED: To allow a receiving entity to derive a longer channel estimate while limiting overhead in an OFDM system.
SOLUTION: A pilot is transmitted on different groups of subbands at different time intervals. N subbands transmit pilots uniformly in M non-overlapping groups and on a different subband group in each time interval, and select all M subband groups at M time intervals. A receiving entity derives an initial impulse response estimate with P channel taps on the basis of the pilot received on one subband group and two longer impulse response estimates with different lengths used for data detection and time tracking. Each longer impulse response estimate may be derived by filtering initial impulse response estimates for a sufficient number of subband groups using a time-domain filter.

摘要： In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The method may be performed by a scheduling entity. The scheduling entity transmits control information in a control portion of the subframe, the control information corresponding to data information within the subframe, transmits the data information in a data portion of the subframe, receives a pilot signal from the set of subordinate entities in a pilot portion of the subframe, and receives an ACK/NACK signal from the set of subordinate entities in an ACK portion of the subframe. The ACK portion is subsequent to the pilot portion of the subframe. The ACK/NACK signal includes acknowledgment information corresponding to the data information. The control portion, the data portion, the pilot portion, and the ACK portion are contained in the same subframe.

摘要： Shared spectrum operation is disclosed for sharing spectrum among multiple wireless deployments. Coordination procedures between and among 2nd and 3rd Tier deployments include the use of beacons transmitted by the 2nd Tier for clearing access to spectrum occupied by 3rd Tier users and multiple 3rd Tier deployments sharing resources using a group-listen before talk (LBT) protocol, rather than a per-node LBT protocol. The 2nd Tier beacon signals are transmitted to alert 3rd Tier users of their presence, which, upon detection, will leave the particular spectrum within a predetermined time. For the shared LBT protocol, the 3rd Tier deployments share the channel with each other through an LBT with random backoff, in which the start time of clear channel assessment (CCA) procedure and the random backoff values are synchronized among nodes of the same deployment.
摘要翻译：披露了共享频谱操作以在多个无线部署之间共享频谱。第二层和第三层部署之间以及之间的协调程序包括使用由第二层传输的信标来清除对第三层用户占用的频谱的访问，以及使用分组先听（LBT）协议共享资源的多个第三层部署。而不是每个节点的LBT协议。发射第二层信标信号以提醒第三层用户他们的存在，这些用户在检测到时将在特定时间内离开特定频谱。对于共享LBT协议，第三层部署通过具有随机退避的LBT相互共享信道，其中清除信道评估（CCA）过程的开始时间和随机退避值在同一部署的节点之间同步。

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support two different modes of operation (e.g., a normal transmission efficiency mode, a high transmission efficiency mode, etc.) either controlled by a network or the UE. The UE may transmit an indication of a capability of supporting the different modes of operation, where the network or the UE determine to use which mode of operation to use based on the transmitted capability. For example, the network may transmit an explicit indication of which mode of operation for the UE to use and/or may transmit an indication of the modes of operation, where the UE determines which mode of operation to use after receiving the indication. Additionally, the UE may determine which mode of operation to use based on being scheduled within or outside of a restricted bandwidth allocated to a mode of operation.
