摘要： Embodiments described provide for resource allocation for a transmission to a wireless device. The frequency band is partitioned into at least two contiguous subbands. A determination is made whether it is desirable to transmit in a single subband or in more than one subband. The transmission is assigned to occur in either the single subband or to operate in more than one subband. If the transmission is restricted to one subband, the hop pattern is also restricted to subcarriers within the particular subband.

摘要： Apparatus and methods for rate prediction in a wireless communication system having fractional frequency reuse are disclosed. A wireless communication system implementing Orthogonal Frequency Division Multiple Access (OFDMA) can implement a fractional frequency reuse plan where a portion of carriers is allocated for terminals not anticipating handoff and another portion of the carriers is reserved for terminals having a higher probability of handoff. Each of the portions can define a reuse set. The terminals can be constrained to frequency hop within a reuse set. The terminal can also be configured to determine a reuse set based on a present assignment of a subset of carriers. The terminal can determine a channel estimate and a channel quality indicator based in part on at least the present reuse set. The terminal can report the channel quality indicator to a source, which can determine a rate based on the index value.

摘要： For an iterative channel and interference estimation and decoding scheme, prior information for channel gain and interference is initially obtained based on received pilot symbols. Forward information for code bits corresponding to received data symbols is derived based on the received data symbols and the prior information and then decoded to obtain feedback information for the code bits corresponding to the received data symbols. A posteriori information for channel gain and interference for each received data symbol is derived based on the feedback information for that received data symbol. The a posteriori information for the received data symbols and the prior information are combined to obtain updated information for channel gain and interference for each received data symbol. The process can be repeated for any number of iterations. The prior, a posteriori , and updated information may be represented by joint probability distributions on channel gain and interference. The forward and feedback information may be represented by log-likelihood ratios.

摘要： Techniques for transmitting null pilots to support interference estimation in a wireless network are described. A null pilot is non-transmission on designated time-frequency resources by a cell or a cluster of cells supporting cooperative transmission to a UE. The received power of the null pilot from the cell or cluster of cells may be indicative of interference from other cells. In one design, a cell in the cluster may determine resources for sending a null pilot by the cell. The cell may transmit the null pilot (i.e., send no transmissions) on the resources to allow UEs to estimate out-of-cluster interference. Some or all cells in the cluster may transmit null pilots on the same resources. The cell may receive interference and channel information from the UE and may send data transmission to the UE based on the interference and/or channel information. Remaining cells in the cluster may reduce interference to the UE.
摘要翻译：描述了用于发送空导频以支持无线网络中的干扰估计的技术。空导频是通过支持向UE的协作传输的小区或小区集群在指定的时间 - 频率资源上进行非传输。来自小区或小区簇的空导频的接收功率可以指示来自其他小区的干扰。在一种设计中，集群中的小区可以确定用于由小区发送空导频的资源。小区可以在资源上发送空导频（即，不发送传输），以允许UE估计簇外干扰。集群中的一些或所有单元可以在相同的资源上传输空导频。小区可以从UE接收干扰和信道信息，并且可以基于干扰和/或信道信息向UE发送数据传输。群集中的剩余小区可以减少对UE的干扰。

摘要： Systems and methodologies are described that facilitate defining new control channels in legacy wireless networks. Control data resources for new systems can be defined over resources reserved for general data communications in the legacy wireless network specification. In this regard, legacy devices can still be supported by devices implementing new control data resources, and the new control data resources can avoid substantial interference that is typically exhibited over legacy control and/or reference signal resources by instead using the general data resources. In addition, new system devices can avoid scheduling data communication resources over the new control resources to create a substantially non-interfered global control segment. Control data can be transmitted over the segment using beacon-based technologies, reuse schemes, and/or the like.

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.

摘要： Systems and methodologies are described that facilitate selecting and/or reselecting one or more access points, related cells, or carriers based at least in part on calculating an energy efficiency related to the access points. In particular, the energy efficiency can be based at least in part on an estimated pathloss and/or a level of interference related to communicating with the access points. Moreover, load parameters related to the access point can be received and evaluated in selecting and/or reselecting the access point. Thus, access points can be selected or reselected based on parameters other than forward link transmit power. In addition, pathloss and/or interference levels can be weighed based on access point type to prevent macrocell overloading.

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.
