摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a base station may transmit data to a relay station in a portion of a subframe instead of the entire subframe. The relay station may transmit control information during part of the subframe. The base station may transmit data to the relay station during the remaining part of the subframe. In another aspect, a target termination for a packet may be selected based on data and/or ACK transmission opportunities available for the packet. One or more transmissions of the packet may be sent with HARQ, and ACK information may be sent for the packet. The packet may be transmitted such that it can be terminated prior to the first subframe (i) not available for sending the packet or (ii) available for sending ACK information.

摘要： Techniques for sending information in a wireless network are described. The network may support (i) regular subframes used to send unicast information and (ii) multicast/broadcast single frequency network (MBSFN) subframes used to send broadcast information and having lower overhead than the regular subframes. In an aspect, MBSFN subframes may be used to mitigate interference. A first base station may cause high interference to stations (e.g., UEs) served by a second base station. The first base station may reserve a subframe for the second base station, send system information conveying the reserved subframe as an MBSFN subframe to its stations, and transmit in a first part of the reserved subframe in accordance with an MBSFN subframe format. The second base station may skip the first part and may send unicast information to its stations in the remaining part of the reserved subframe. In another aspect, MBSFN subframes may be used to support additional base station capabilities.

摘要： Methods, apparatuses, and computer program products are disclosed for encoding/decoding a wireless control signal. For encoding, control bits are received and encoded with a first error control code so as to create a first set of encoded bits. The encoded bits are then encoded with a second error control code so as to create a second set of encoded bits, which are modulated as beacon tones and subsequently transmitted. For decoding, beacon tones corresponding to a set of control bits are received and subsequently demodulated so as to ascertain a set of demodulated bits. The demodulated bits are then decoded with a decoder so as to ascertain a set of decoded bits. The decoded bits are then decoded with a second decoder so as to ascertain a second set of decoded bits, which includes the set of control bits.

摘要： Systems and methodologies are described that facilitate transmitting positioning reference signals (PRS) differently for passive distributed elements. PRSs for passive distributed elements can be transmitted over disparate resources than those utilized for PRSs at a related access point, using different symbol sequences, and/or the like. In this regard, wireless devices can differentiate between PRSs from access points and those from passive distributed elements, which can mitigate confusion for processes involving such RSs, such as position determining. Alternatively, passive distributed elements can refrain from transmitting PRSs, and a corresponding access point can indicate to wireless devices to only determine positioning based on PRSs. Thus, the wireless devices can utilize the PRSs transmitted from the access point (and not other reference signals transmitted from the passive distributed element) to determine a position.
摘要翻译：描述了有助于以无源分布式元件不同地传送定位参考信号（PRS）的系统和方法。用于被动分布式元件的PRS可以在不同资源上传输，而不是使用不同的符号序列等在相关接入点用于PRS的资源。在这方面，无线设备可以区分来自接入点的PRS和来自被动分布元件的PRS，其可以减轻涉及这种RS的过程的混淆，诸如位置确定。或者，被动分布式元件可以避免传输PRS，相应的接入点可以向无线设备指示仅基于PRS确定定位。因此，无线设备可以利用从接入点发送的PRS（而不是从被动分布式元件发送的其他参考信号）来确定位置。

摘要： First technique (fig. 5) : a signalling message, e.g., a reduce interference request is sent by mapping it to at least one specific subcarrier (m) among a set of subcarriers reserved for sending the signalling message (0, 1, 2,..., m,..., M-1). The at least one subcarrier is selected based on the message value. A signal is then sent on the at least one subcarrier (m) in multiple symbol periods to convey the signalling message. Second technique (fig. 6) : a reduce interference request is sent by mapping it into an orthogonal sequence {u?, ul,..., uM-1} of length M, among a set of M orthogonal sequences. The sequence is selected based on the message value. The sequence is sent on a resource segment, formed by T symbol periods and N subcarriers, wherein T*N=M. Third technique (fig. 7) : a reduce interference request is processed to obtain modulation symbols, and each modulation symbol is then spread, by means of a known reference signal sequence r(n), across multiple subcarriers in one symbol period.

摘要： In a wireless communication system, short-term interference mitigation may be used to mitigate (e.g., to avoid or reduce) interference on a given link in order to improve performance of data transmission. The interference mitigation reduces transmit power of interfering transmissions so that a higher signal-to-noise-and-interference ratio (SINR) can be achieved for a desired data transmission. A node may observe high interference from an interfering node that degrades performance of data transmission sent on that link. By taking advantage of an communication path with the interfering node (e.g., wireless data/control channel, backhaul network connection, or analog broadcast signal), the transmitting node can successfully complete time critical communications while allowing the interfering node to also simultaneously communicate without reducing overall resources nor burdening any managing nodes.
摘要翻译：在无线通信系统中，可以使用短期干扰减轻来减轻（例如，以避免或减少）给定链路上的干扰，以便提高数据传输的性能。干扰减轻降低干扰传输的发射功率，从而可以实现更高的信噪比干扰比（SINR），用于所需的数据传输。节点可能会观察到来自干扰节点的高干扰，从而降低在该链路上发送的数据传输的性能。通过利用与干扰节点（例如，无线数据/控制信道，回程网络连接或模拟广播信号）的通信路径，发送节点可以成功地完成时间关键通信，同时允许干扰节点同时通信而不减少整体资源也不负责管理节点。

摘要： Techniques for transmitting overload indicators over the air to UEs in neighbor cells are described. In one design, an overload indicator may be transmitted as a phase difference between at least one synchronization signal and a reference signal for a cell. In another design, an overload indicator may be transmitted as a phase difference between consecutive transmissions of at least one synchronization signal for a cell. In yet another design, an overload indicator may be transmitted by a cell on resources reserved for transmitting the overload indicator. In yet another design, an overload indicator may be transmitted by a cell on a low reuse channel or a broadcast channel. For all designs, a UE may receive overload indicators from neighbor cells, determine the loading of each neighbor cell based on the overload indicator for that cell, and control its operation based on the loading of the neighbor cells.

摘要： Systems and methodologies are described herein that facilitate generation and processing of control signaling to support uplink network multiple-in-multiple-out (N-MIMO) communication in a wireless communication system. As described herein, respective network nodes associated with an uplink N-MIMO framework can generate channel state information (CSI) corresponding to an uplink channel from a designated network user to the respective nodes. Generated CSI can subsequently be communicated to an uplink anchor node for the network user in order to facilitate rate assignment, scheduling, and/or other operations with respect to the network user. As described herein, CSI generated and reported by respective cells can include channel profiles, carrier/interference profiles, estimated supported uplink rates, or the like. As additionally described herein, supplemental information such as observed interference levels, demodulation indicators, or the like can be communicated to an anchor node and utilized in rate assignment and/or scheduling.
