摘要： Techniques for sending acknowledgement (ACK) information for data transmission are described. In one design, a receiver receives a transmission of data, processes the received transmission to decode the data, and generates ACK information for the data prior to decoding all of the data. The receiver may generate the ACK information based on decoding results for a portion of the data and/or received signal quality of the received transmission. The receiver may send the ACK information at a designated ACK transmission time prior to completing decoding for all of the data. The receiver may receive a transmission of multiple (K) packets and may generate ACK information for these K packets after decoding L packets, where 1≤ L

摘要： A hierarchical cyclic redundancy check (CRC) is provided that enables CRC appending and detection. A message that includes a first message portion and a second message portion is transmitted to two or more receivers. The receivers are not aware of the first message portion. One of the receivers can be aware of the second message portion of the message. Each portion of the message can be encoded with a CRC in order to provide protection. The receiver that is aware of the second message portion is provided a higher level of cyclic redundancy check (CRC) protection than the receivers that are not aware of the second message portions.

摘要： An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.

摘要： Providing for base station (BS) acquisition in semi-planned or unplanned wireless access networks is described herein. By way of example, a signal preamble can be dynamically allocated to wireless signal resources, such that the preamble is scheduled to different resource(s) across different cycles of the signal. Dynamic allocation can be pseudo-random, based on collision feedback, or determined by a suitable algorithm to mitigate collisions from a dominant interferer. In addition, dynamic scheduling can be particular to a type of BS to significantly reduce collisions from BSs of disparate types. In at least one aspect, a preamble resource can be subdivided into multiple frequency sub-carrier tiles. Control channel information can be transmitted on 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：这里描述了在半计划或非计划无线接入网络中提供基站（BS）获取。举例来说，可以将信号前导码动态分配给无线信号资源，使得在信号的不同周期内将前导码调度到不同的资源。动态分配可以是伪随机的，基于碰撞反馈，或者由合适的算法确定以减轻来自主要干扰源的冲突。另外，动态调度对于一类BS来说是特定的，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成多个频率子载波瓦片。控制信道信息可以在一组这样的瓦片的每个瓦片上传输，进一步减轻主要干扰对瓦片组的子集的影响。

摘要： Techniques for transmitting data with persistent interference mitigation in a wireless communication system are described. A station (e.g., a base station or a terminal) may observe high interference and may send a request to reduce interference to interfering stations. The request may be 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 receive a response from each interfering station indicating grant or dismissal of the request by that interfering station in each response period. The station may estimate SINR based on the response received from each interfering station and may exchange data with another station based on the estimated SINR. Persistent interference mitigation may reduce signaling overhead and improve resource utilization and performance.
摘要翻译：描述了在无线通信系统中传输具有持续干扰减轻的数据的技术。站（例如，基站或终端）可以观察到高干扰，并且可以发送减少对干扰站的干扰的请求。该请求可以在覆盖多个响应周期的时间段内有效。每个干扰站可以在每个响应周期中授权或者解除请求，可以通过全功率发射来解除请求，并且可以以低于全功率的方式发送请求。站点可以从每个干扰站接收指示在每个响应周期中该干扰站的请求的授权或解除的响应。该站可以基于从每个干扰站接收到的响应估计SINR，并且可以基于估计的SINR与另一个站交换数据。持续的干扰减轻可以减少信令开销并提高资源利用率和性能。

摘要： Providing for management of wireless communications in a heterogeneous wireless access point (AP) environment is described herein. By way of example, system data of an over-the-air message can be configured to include information identifying a distinct type of transmitting base station. In some aspects, the information can include an access type of the base station and/or a sector ID for distinguishing the base station among large numbers of other base stations. According to other aspects, system data transmitted on the wireless signal can include wireless channel resources designated for a particular type of base station, or blanked by the transmitting base station, to facilitate interference reduction on such resources. By employing aspects of wireless communication management disclosed herein, efficient and reliable communication can be affected in large heterogeneous AP networks.

摘要： Systems and methodologies are described that facilitate blanking on portions of bandwidth utilized by communicating devices that are dominantly interfered by a disparate device in wireless communications networks. The portions of bandwidth can relate to critical data, such as control data, and one or more of the communicating devices can request that the dominantly interfering device blank on one or more of the portions. The communicating devices can subsequently transmit data over the blanked portions free of the dominant interference. Additionally, the dominantly interfering device can request reciprocal blanking from the one or more communicating devices.

摘要： Techniques for sending control information in a wireless communication system are described. A control segment may include tiles, and each tile may include a number of transmission units. A number of control resources may be defined and mapped to the transmission units for the control segment. For symmetric mapping, multiple sets of control resources may be formed, and each batch of L consecutive sets of S control resources may be mapped to S transmission units at the same location in the L tiles. For localized mapping, each set of S control resources may be mapped to a cluster of S adjacent transmission units in one tile. For distributed mapping, each control resource may be mapped to one transmission unit in one tile. For diversity, each control resource may be mapped to multiple (e.g., three) transmission units in at least one tile.
