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： Techniques for transmitting information using beacon symbols in a wireless communication system are described. In one design, a transmitter may map information to multiple subcarriers among a plurality of subcarriers, with the information being conveyed by the position of the multiple subcarriers. The transmitter may map the information to at least one non-binary symbol. The transmitter may then determine each of the multiple subcarriers based on one non-binary symbol or may determine all of the multiple subcarriers based on one non-binary symbol. The transmitter may generate a beacon symbol having the information mapped to the multiple subcarriers. The transmitter may use higher transmit power for the multiple subcarriers to allow receivers with low geometry to reliably receive the information. The use of multiple subcarriers may allow more information to be sent in the beacon symbol and may also improve frequency diversity.
摘要翻译：描述了在无线通信系统中使用信标符号发送信息的技术。在一种设计中，发射机可以将信息映射到多个子载波中的多个子载波，信息由多个子载波的位置传送。发射机可以将信息映射到至少一个非二进制符号。然后，发射机可以基于一个非二进制符号来确定多个子载波中的每一个，或者可以基于一个非二进制符号来确定所有多个子载波。发射机可以生成具有映射到多个子载波的信息的信标符号。发射机可以为多个子载波使用更高的发射功率，以允许具有低几何形状的接收机可靠地接收信息。多个子载波的使用可以允许在信标符号中发送更多的信息，并且还可以提高频率分集。

摘要： Acknowledgments (ACKs/ NACKs) are suppressed when transmitting non-decodable packets in a communication system that utilizes HARQ. Non-decodable packets are transmitted to save system bandwidth and make the overall spectral efficiency higher. The transmitter and receiver know that in HARQ when the transmitter transmits a non-decodable packet to the receiver, this will cause the receiver to automatically transmit back a NACK. The transmitter and receiver exploit this fact by discarding and/or not transmitting the NACK (respectively).
摘要翻译：在使用HARQ的通信系统中发送不可解码分组时，确认（ACK / NACK）被抑制。传输不可解码数据包以节省系统带宽，使总体频谱效率更高。发射机和接收机知道，当发射机向接收机发送不可解码的分组时，在HARQ中，这将导致接收机自动发送NACK。发射机和接收机通过分别丢弃和/或不发送NACK来分别利用这一事实。

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 sending control messages are described. In an aspect, assignment messages may be acknowledged based on either linked or dedicated acknowledgement (ACK) resources. A terminal may receive an assignment message from a base station, determine whether to acknowledge the assignment message, and determine ACK resources to use to acknowledge the assignment message. The ACK resources may be linked to a control block on which the assignment message was received, linked to resources given by the assignment message, or assigned to the terminal. The terminal may send the acknowledgement on the ACK resources. In another aspect, a control message may be acknowledged based on ACK resources determined based on the control message or the control block. The ACK resources may be linked to resources assigned by the control message or linked to the control message. The terminal may send an acknowledgement for the control message on the ACK resources.

摘要： Pilots are transmitted on demand on a reverse link and used for channel estimation and data transmission on a forward link. A base station selects at least one terminal for on-demand pilot transmission on the reverse link. Each selected terminal is a candidate for receiving data transmission on the forward link. The base station assigns each selected terminal with a time-frequency allocation, which may be for a wideband pilot, a narrowband pilot, or some other type of pilot. The base station receives and processes on-demand pilot transmission from each selected terminal and derives a channel estimate for the terminal based on the received pilot transmission. The base station may schedule terminals for data transmission on the forward link based on the channel estimates for all selected terminals. The base station may also process data (e.g., perform beamforming or eigensteering) for transmission to each scheduled terminal based on its channel estimate.

摘要： Techniques are discussed herein identify transmission strategies and to communicate those identified transmission strategies in a transparent communication environment. In some examples, a user equipment (UE) may identify a new transmission strategy for a downlink channel different from a current transmission strategy for the down link channel. The UE may transmit a channel state information (CSI) message that includes an indication of the new transmission strategy identified by the UE. In some examples, a base station may identify the new transmission strategy for the downlink channel. The base station may transmit a codebook subset restriction (CSR) indicator that includes an indication of the new transmission strategy identified by the base station. In some examples, the UE may modify its feedback strategy based 0n the new transmission strategy.

摘要： Systems and methodologies are described that facilitate resource scaling for inter-access point fairness in a wireless communication system. As described herein, an offered load of an access point can be determined based on one or more loading metrics relating to associated terminals, throughput, data rate, quality of service (QoS), or the like. Based on the determined offered load of an access point, resources used by the access point and/or power utilized for communication over those resources can be scaled based on a comparison of the offered load of the access point to a nominal or default offered load. Centralized techniques for resource scaling are described herein, wherein one or more centralized controllers coordinate resource scaling with respective access points via backhaul messaging. In addition, distributed techniques for resource scaling are described herein, wherein neighboring access points communicate with each other via over-the-air messaging to determine a local optimal resource apportionment.
