摘要： Techniques for transmitting data in a relay communication network are described. In an aspect, stations in the relay network may be grouped into multiple depths, and stations at each depth may send the same transmission in each time interval. Packets may be transmitted in a pipelined manner in the relay network. Transmissions of a packet may be sent by stations at progressively higher depth in successive time intervals. A station may perform auto-configuration, attempt to decode transmissions from stations at different depths, and determine its depth based on decoding results. In another aspect, stations at each depth may transmit the same synchronization signal, and stations at different depths may transmit different synchronization signals. In one design, the synchronization signals for different depths may be different pilots, which may be generated with different scrambling codes or different orthogonal codes or may be multiplexed in frequency and/or time.

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： 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 supporting peer-to-peer (P2P) communication are disclosed. In an aspect, a device performs peer discovery based on trigger events. In one design, the device detects an event triggering peer discovery, which may be an application becoming active on the device, a change in the position of the device, the device being turned on, etc. The device performs peer discovery based on detection of the event triggering peer discovery. In one design, the device starts peer discovery in response to detecting the trigger event. In another design, the device changes at least one characteristic (e.g., the periodicity) of peer discovery in response to detecting the trigger event. In another design, a device determines an application becoming active on the device. The device transmits a query (e.g., in a proximity detection signal) to request for a service from a peer device to support the application.

摘要： Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

摘要： Systems and methodologies are described herein that facilitate interference measurement and reporting in a network multiple-in-multiple-out (N-MIMO) communication system. As described herein, a network device can measure and report interference corresponding to network nodes outside a designated set of nodes that can cooperatively serve the device. Respective interference reports can additionally identify dominant interfering nodes, correlation between transmit antennas of respective nodes, or the like. Subsequently, respective interference reports can be combined with per-node channel information to manage coordination and scheduling across respective network nodes. As further described herein, interference from a network node can be measured by observing reference and/or synchronization signals from the network node. To aid such observation, respective non-interfering network nodes can define null pilot intervals in which transmission is silenced or otherwise reduced. As additionally described herein, loading information broadcasted by respective interfering network nodes can be identified and utilized in connection with interference calculation.

摘要： Techniques for sending control information in a wireless network are described. In an aspect, a hierarchical control channel structure may be used, a first group of control channels may be sent in a low reuse segment, and a second group of control channels may be sent in a non-reuse segment. In another aspect, a first control channel is sent in the low reuse segment and is used to configure a second control channel sent in the non-reuse segment so that the second control channel can be reliably received in dominant interference scenarios. In one design, a first base station sends a first message on a first control channel to a user equipment (UE). The UE sends a second message to an interfering base station to request it to reduce interference to a second control channel. The first base station sends control information on the second control channel to the UE.

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.
