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.

摘要： Techniques for transmitting data in a communication system are described. A packet may be partitioned into multiple subpackets, and each subpacket may be encoded separately. The subpackets may be mapped to resources assigned for transmission of the packet, with at least one subpacket being mapped to a subset of the assigned resources. The assigned resources may include multiple tiles, with each tile corresponding to a block of time frequency resources. The subpackets may be mapped to the tiles such that (i) the subpackets are mapped to equal number of tiles to achieve similar decoding performance, (ii) each subpacket is mapped to at least NMIN tiles, if available, to achieve a certain minimum diversity order for the subpacket, and/or (iii) each subpacket is mapped to a subset of the multiple tiles, if possible, so that the subpacket can be decoded without having to demodulate all of the tiles.

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 send a first message to at least one interfering station to request reduction of interference on at least one resource. The first station may send the first message in anticipation of receiving data on the at least one resource. An interfering station may receive the first message from the first station and may reduce interference on the at least one resource by reducing its transmit power and/or by steering its power in a direction different from the first station. The first station may thereafter receive data from a second station on the at least one resource. The techniques may be used for data transmission on the forward and reverse links.

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.
摘要翻译：信标符号在OFDM系统中从基站周期性地发送。基站的整个功率或其大部分集中在这些符号中，因此它们被移动台非常容易地识别。发送这些符号的频率和它们被发送的时间将诸如基站/扇区标识和给定基站/扇区的优选载波的信息传送给移动站。为了避免不同基站和扇区的信标符号之间的冲突，来自不同基站/扇区的信标符号在不同的符号时间和不同子载波上发送。

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a serving base station may send a message to a terminal to trigger short-term interference mitigation. In response, the terminal may send a message to request at least one interfering base station to reduce interference on at least one resource. Each interfering base station may determine a transmit power level to be used for the at least one resource and may send a pilot at this transmit power level. The terminal may estimate the channel quality of the at least one resource based on at least one pilot received from the at least one interfering base station. The terminal may send information indicative of the estimated channel quality to the serving base station. The serving base station may send a data transmission on the at least one resource to the terminal.

摘要： Signaling-only access may be established with an access node (104) under certain circumstances such as, for example, upon determining that a node (102) is not authorized for data access at the access node (102). A node (104) that is not authorized for data access at an access node (104) may still be paged by the access node (104) through the use of signaling-only access. In this way, transmissions by the access node (104) may not interfere with the reception of pages at the node (302). A first node may be selected for providing paging (102) while a second node (106) is selected for access (304) under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

摘要： Techniques for managing interference in a wireless network are described. A base station may receive enhanced pilot measurement reports from user equipments (UEs) and may make an interference management decision based on the received reports. The base station may select a serving base station for a UE based on an enhanced pilot measurement report received from the UE. The base station may determine resources with a low target interference level at a neighbor base station and may avoid scheduling a UE for uplink transmission on the resources. The base station may also determine whether to reserve resources for a neighbor base station based on data performance of the neighbor base station, whether the neighbor base station observes high interference from UEs served by the base station, or whether UEs served by the neighbor base station observe high interference from the base station, which may be determined based on the enhanced pilot measurement reports.
