摘要： Systems and methodologies are described that facilitate mitigation of interference through uplink scheduling in a wireless communication environment. Access points can assign multiple terminals to a single tile or segment of shared resource (e.g., a time frequency region) to maximize the number of terminals supported. However, combinations of certain types of terminals can cause a significant increase in interference. In particular, allocating multiple terminals having a relatively high velocity (e.g., terminals located in moving vehicles) to a single tile can cause an unacceptable increase in interference. To mitigate interference, high velocity terminals can be identified. Once identified, terminals can be allocated to the available tiles based at least in part upon avoiding combinations that result in a significant increase in interference.

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： Techniques for transmitting signaling with localized spreading are described. In one design, a transmitter (e.g., a base station) spreads multiple signaling symbols to obtain multiple sets of output symbols and further maps the multiple sets of output symbols to multiple time frequency blocks. The spreading may be localized to each time frequency block. Prior to the spreading, the transmitter may scale the multiple signaling symbols with multiple gains determined based on the transmit power for these signaling symbols. The transmitter may scramble the scaled signaling symbols to obtain scrambled symbols and may spread the scrambled symbols to obtain the multiple sets of output symbols. The transmitter may map each set of output symbols to a respective time frequency block.

摘要： Interference management is provided through use of a user-based interference control and/or a network-based interference control. For user-based interference control, the terminals are informed of the inter-sector interference observed by the neighbor sectors and can adjust their transmit powers accordingly so that the inter-sector interference is maintained within acceptable levels. For network-based interference control, each sector is informed of the inter-sector interference observed by the neighbor sectors and regulates data transmissions for its terminals such that the inter-sector interference is maintained within acceptable levels. Each system may utilize only user-based interference control, or only network-based interference control, or both.

摘要： Systems and methodologies are described that facilitate effectuating inter-technology handoffs utilizing pilots. A sector can utilize a first technology to communicate on a first bandwidth. Further, to indicate presence of the first technology, the sector can transmit a pilot on a second bandwidth (e.g., where the second bandwidth can be utilized with a second technology). While a mobile device is communicating data utilizing the second technology upon the second bandwidth, the pilot related to the first technology can be obtained. Based upon the pilot, communication of data (e.g., received and/or transmitted by the mobile device) can be switched to using the first technology on the first bandwidth. Accordingly, the mobile device need not discontinue communicating data with the second technology prior to identifying availability of the first technology and/or initiating handoff to the first technology.

摘要： Beacon symbols are sent periodically from the base stations in an OFDM system. The entire power of the base station, or a large portion of it is concentrated in these symbols, thus they are very easily recognized by the mobile stations. The frequencies upon which these symbols are transmitted and the time at which they are transmitted communicates information such as the base station/sector identity and the preferred carrier of the given base station/sector to the mobile station. In order to avoid collision between the beacon symbols of different base stations and sectors, the beacon symbols from different base stations/sectors are transmitted at different symbols times and on different subcarriers.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may receive a message sent by a second station to request reduction of interference on at least one resource. In response to receiving the message, the first station may determine a first transmit power level to use for the at least one resource based on one or more factors such as a priority metric sent in the message, the buffer size at the first station, etc. The first station may send a power decision pilot on the at least one resource at a second transmit power level determined based on the first transmit power level.

摘要： Techniques for encoding and decoding data are described. In an aspect, multiple code rates for a forward error correction (FEC) code may be supported, and a suitable code rate may be selected based on packet size. A transmitter may obtain at least one threshold to use for code rate selection, determine a packet size to use for data transmission, and select a code rate from among the multiple code rates based on the packet size and the at least one threshold. In another aspect, multiple FEC codes of different types (e.g., Turbo, LDPC, and convolutional codes) may be supported, and a suitable FEC code may be selected based on packet size. The transmitter may obtain at least one threshold to use for FEC code selection and may select an FEC code from among the multiple FEC codes based on the packet size and the at least one threshold.
