摘要： Systems and methodologies are described that facilitate transmitting control information in wireless networks. Portions of bandwidth can be blanked for transmitting control information, and the control information transmitters can utilize beacon symbols to convey the control information. In this regard, interference is mitigated with respect to data transmissions over the control information bandwidth. Selected frequencies of the beacon symbols in a codeword can be used to indicate the control information. The codewords can be encoded with an error control code to provide redundancy for decoding in the presence of some interference.

摘要： Systems and methodologies are described that facilitate transmitting access point types and/or restricted association parameters using broadcast signals, such as beacons, pilot signals, etc. The type or restricted association information can be indicated by one or more intrinsic aspects of the signal, such as specified parameters. In addition, the type or information can be indicated by one or more extrinsic signal aspects, such as frequency, interval, periodicity, etc. Using this information, a mobile device can determine whether an access point implements restricted association. If so, the mobile device can request an access point or related group identifier before determining whether to establish connection therewith. The identifier can be verified against a list of accessible access points and/or groups to make the determination.

摘要： Systems and methodologies are described that generate pilots for signal acquisition in a wireless communication system based on time domain sequences. The pilots may be generated by a base station and transmitted in a pilot field to one or more access terminals to aid in signal acquisition at each of the access terminals. One of the pilots may be common to all access points in the wireless communication system, thereby allowing an access terminal to obtain a timing estimate for the system while minimizing the effects of interference variations between base stations. Further, one or more generated pilots may be unique to each access point in order to allow each respective access point to be identified by its generated pilots.

摘要： Techniques for allocating and mapping resources in a wireless communication system are described. The system may use hop-ports to facilitate allocation and use of subcarriers. In one aspect, the hop-ports may be partitioned into multiple subzones, with each subzone including a configurable number of hop-ports. The hop-ports within each subzone may be permuted or shuffled based on a permutation function. After permutation, the hop-ports in all subzones may be mapped to the subcarriers based on local or global hopping. In another aspect, a set of hop-ports may be mapped to a set of subcarriers. A hop-port may be mapped to an unavailable subcarrier and may then be remapped to another available subcarrier. In yet another aspect, a set of hop-ports may be mapped to a set of subcarriers distributed (e.g., evenly) across all subcarriers but avoiding subcarriers in a reserved zone.

摘要： Systems and methodologies are described that provide support for signal acquisition in wireless communication systems that utilize half-duplex communication in the presence of asynchronous sectors. Forward link and reverse link superframes can be structured such that a given frame position in a superframe alternates between forward link communication and reverse link communication for a particular half-duplex interlace. More particularly, an odd number of frames can be grouped into respective forward link and reverse link superframes, from which frames can be assigned to a first half-duplex interlace and a second half-duplex interlace in an alternating fashion. By varying the communication link used by a half-duplex interlace at a given frame location, terminals operating on a single half-duplex interlace can detect asynchronously operating sectors irrespective of the transmission timeline of such sectors.
摘要翻译：描述了在存在异步扇区的情况下利用半双工通信的无线通信系统中的信号获取的支持的系统和方法。可以构造前向链路和反向链路超帧，使得超帧中的给定帧位置在特定半双工交错的前向链路通信和反向链路通信之间交替。更具体地，奇数帧可以被分组成相应的前向链路和反向链路超帧，从该帧可以以交替的方式将帧分配给第一半双工交错和第二半双工交错。通过改变在给定帧位置处的半双工交错使用的通信链路，在单个半双工交错上操作的终端可以检测异步操作扇区，而与这些扇区的传输时间线无关。

摘要： Systems and methodologies are described that facilitate silence interval specification and utilization in wireless communications. In particular, a silence interval can be defined such that communications cease during the interval, defined by an interval period, offset within the interval period, and duration; the communication can be that of mobile devices to base stations in a wireless communication network. In this regard, base stations can measure thermal noise during the silence to set a interference over thermal (IoT) level in one example. Additionally, other systems and networks can use the silence intervals to transmit, such as public safety devices and/or peer-to-peer communication. The wireless mobile devices can receive the silence interval information and appropriately blank out communications during the defined period.

摘要： Systems and methods that facilitate management of interference and communication resources are provided. A differential approach is devised in which other-sector interference (OSI) and communication resources are managed by adjusting an offset (delta) value associated with the resources in response to receiving an indication of other-sector interference. An OSI indication can be issued based on a short and a long time scale, and effective interference metrics over time-frequency resources. The adjusted delta value is communicated to a serving access point, which reassigns communication resources in order to mitigate other-sector interference.

摘要： Systems and methodologies are described that facilitate multiplexing control data values over a single physical control channel at least in part by dividing the control channel into one or more logical channels. The physical control channel can have a corresponding Walsh space for transmitting a number of bits, or representations thereof, and the Walsh space can be divided among the logical control channels. Additionally, the logical control channels and/or physical channel can be scrambled according to an identifier of a mobile device (such as MAC ID) to differentiate the data on the channel. Furthermore, a sector identifier can be used to scramble the data where the sector is ascertainable.
