摘要： PROBLEM TO BE SOLVED: To perform base station (BS) acquisition in semi-planned or unplanned wireless access networks.SOLUTION: A signal preamble is dynamically allocated to wireless signal resources, such that the preamble is scheduled in different resources across different cycles of the signal. The dynamic allocation is pseudo-random, on the basis of collision feedback, or determined by a suitable algorithm to mitigate collisions from a dominant interference. In addition, the dynamic scheduling can be specific to a type of BS to significantly reduce collisions from BSs of disparate types. In at least one aspect, a preamble resource can be sub-divided into multiple frequency sub-carrier tiles. Control channel information is transmitted to each tile of a group of such tiles, further mitigating effects of a dominant interferer on a subset of the tile group.
摘要翻译：要解决的问题：在半计划或非计划无线接入网络中执行基站（BS）采集。解决方案：信号前导码被动态地分配给无线信号资源，使得前导码在不同的资源中被调度在不同的周期信号。动态分配是基于碰撞反馈的伪随机，或由适当的算法确定的，以减轻来自主导干扰的冲突。此外，动态调度可以特定于BS的类型，以显着减少来自不同类型的BS的冲突。在至少一个方面，前导码资源可以被细分为多个频率子载波瓦片。控制信道信息被发送到一组这样的瓦片的每个瓦片，进一步减轻显着干扰源对瓦片组的子集的影响。

摘要： PROBLEM TO BE SOLVED: To provide a wireless communication apparatus which properly adjusts transmit timing of base stations and UEs.SOLUTION: Techniques for adjusting transmit timing of base stations and user equipment (UE) in a wireless network are described. In one operating scenario, a femto base station communicates with a femto UE, and a macro base station communicates with a macro UE located within the coverage of the femto base station. In an aspect, the transmit timing of the femto base station may be delayed relative to the transmit timing of the macro base station, e.g., to time align downlink signals from the femto and macro base stations at the femto UE and the macro UE. In another aspect, the transmit timing of the femto UE may be advanced relative to the transmit timing of the femto base station by an amount larger than twice the propagation delay between the femto UE and the femto base station, e.g., to time align uplink signals from the femto UE and the macro UE at the femto base station.

摘要： PROBLEM TO BE SOLVED: To provide a method for sending information in a wireless network.SOLUTION: The wireless network may support (i) regular subframes used to send unicast information and (ii) MBSFN subframes used to send broadcast information. MBSFN subframes may be used to mitigate interference. A first base station may cause high interference to stations (e.g., UEs) served by a second base station. The first base station may reserve a subframe for the second base station, send system information conveying the reserved subframe as an MBSFN subframe to its stations, and transmit in a first part of the reserved subframe in accordance with an MBSFN subframe format. The second base station may skip the first part and may send unicast information to its stations in the remaining part of the reserved subframe.

摘要： PROBLEM TO BE SOLVED: To provide techniques for supporting operation of relay stations.SOLUTION: A bitmap may be sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. The bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. UE may use the bitmap to control operation thereof. UE may perform channel estimation or measurement for the subframes of the first type and may skip channel estimation and measurement for the subframes of the second type. A base station may transmit data and/or control information on resources not used by a relay station to transmit a reference signal. This may avoid interference to the reference signal from the relay station, which may improve performance for UE communicating with the relay station.
摘要翻译：要解决的问题：提供支持中继站操作的技术。解决方案：基站和/或中继站可以发送位图以识别多个无线电帧中的至少两种类型的子帧。位图可以指示位图所覆盖的每个子帧是否是第一类型或第二类型。 UE可以使用位图来控制其操作。 UE可以对第一类型的子帧执行信道估计或测量，并且可以跳过第二类型的子帧的信道估计和测量。基站可以发送关于中继站未使用的资源的数据和/或控制信息以发送参考信号。这可以避免对来自中继站的参考信号的干扰，这可以提高UE与中继站通信的性能。

摘要： PROBLEM TO BE SOLVED: To provide techniques for transmitting data with persistent interference mitigation in a wireless communication system.SOLUTION: A station (e.g., a base station or a terminal) sends a request to reduce interference to interfering stations. The request is valid for a time period covering multiple response periods. Each interfering station may grant or dismiss the request in each response period, may dismiss the request by transmitting at full power, and may grant the request by transmitting at lower than full power. The station may estimate SINR on the basis of the response received from each interfering station and exchanges data with another station on the basis of the estimated SINR. Persistent interference mitigation may reduce signaling overhead and improve resource utilization and performance.

摘要： PROBLEM TO BE SOLVED: To blank control resources in heterogeneous network deployments.SOLUTION: An eNB, such as a macrocell, femtocell or picocell eNB, transmits a downlink control blanking message to a UE directing the UE to perform blanking or request the blanking from the interfering eNBs or devices. The downlink control blanking message can specify the desired control resources and/or information to determine the control resources. Dynamic control blanking is provided to mitigate interference over control resources for the small scale eNB. The small scale eNB can communicate control data to the UE over the control resources. The control data can include a resource blanking message that similarly directs the UE to request blanking of data resources from the interfering eNBs or devices.

摘要： PROBLEM TO BE SOLVED: To provide a technique for short-term interference reduction in an asynchronous wireless communication network.SOLUTION: Frequency resources (control resource and pilot resource) are prepared to transmit an interference reduction request and a pilot between asynchronous wireless communication networks. A first station (for example, a terminal) transmits a request to reduce interference to at least one interference station, on the prepared control resource. The first station receives a pilot transmitted from each interference station on the prepared pilot resource. The prepared resources are combined with a data resource. Based on the pilot, the first station estimates reception signal quality of the data resource. After the interference station reduces interference, the first station receives data transmitted by a second station (for example, a service provision base station) on the data resource.

摘要： PROBLEM TO BE SOLVED: To provide improvements for employing supplemental base stations or access points.SOLUTION: Prior signaling is employed between a macro base station and a set of associated supplemental nodes to support pending wireless communication with a user terminal. The prior signaling includes control or data traffic transmitted to/received from the user terminal. The supplemental nodes can synchronize transmission or reception of the control or data traffic transmissions with similar transmission or reception of the macro base station. The supplemental nodes can replicate pilot signal transmissions on OFDM symbols employed by the macro base station for pilot signals, to give consistent downlink channel for both traffic and pilot signals. The user terminal can observe consistent pilot transmissions over various time slots, as well as concurrent traffic transmissions that can generally be decoded with a common reference signal.
