摘要： Techniques for supporting data transmission via a relay station are described. In an aspect, data transmission may be supported using ACK-and-suspend. A transmitter station sends a first transmission of a packet to a receiver station. The transmitter station receives no ACK information for the first transmission of the packet and suspends transmission of the packet. The transmitter station thereafter receives an indication to resume transmission of the packet and, in response, sends a second transmission of the packet. In another aspect, different ACK timeline may be used when applicable. The receiver station may send ACK information in a designated subframe if available for use or in a different subframe. In yet another aspect, ACK repetition may be used. The receiver may send ACK information in multiple subframes to facilitate reception of the ACK information when the transmitter station is unable to receive one or more of the multiple subframes.
摘要翻译：描述了通过中继站支持数据传输的技术。在一方面，可以使用ACK和挂起来支持数据传输。发送站发送分组的第一次发送到接收站。发送台不接收用于分组的第一次发送的ACK信息，并且暂停分组的发送。然后，发送站接收到恢复分组的发送的指示，并且作为响应，发送分组的第二发送。在另一方面，当适用时可以使用不同的ACK时间线。如果可以使用或在不同的子帧中，则接收站可以在指定的子帧中发送ACK信息。在另一方面，可以使用ACK重复。接收机可以在多个子帧中发送ACK信息，以便当发射机站不能接收多个子帧中的一个或多个时，接收ACK信息。

摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a bitmap may be sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. For example, the bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. UEs may use the bitmap to control their operation. For example, a UE may perform channel estimation or measurement for the subframes of the first type and may skip channel estimation and measurement for the subframes of the second type. In another aspect, a base station may transmit data and/or control information on resources not used by a relay station to transmit a reference signal. This may avoid interference to the reference signal from the relay station, which may improve performance for UEs communicating with the relay station.
摘要翻译：描述了用于支持无线通信系统中的中继站操作的技术。在一个方面，可以由基站和/或中继站发送位图以识别多个无线电帧中的至少两种类型的子帧。例如，位图可以指示位图覆盖的每个子帧是第一类型还是第二类型。 UE可以使用该位图来控制其操作。例如，UE可以针对第一类型的子帧执行信道估计或测量，并且可以跳过针对第二类型的子帧的信道估计和测量。另一方面，基站可以在没有被中继站用来传输参考信号的资源上传输数据和/或控制信息。这可以避免对来自中继站的参考信号的干扰，这可以提高与中继站通信的UE的性能。

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.
摘要翻译：描述了用于支持无线通信系统中的中继站的操作的技术。在一方面，基站可以在子帧的一部分而不是整个子帧中向中继站发送数据。中继站可以在子帧的一部分期间发送控制信息。基站可以在子帧的剩余部分期间向中继站发送数据。在另一方面，可以基于可用于分组的数据和/或ACK传输机会来选择分组的目标终止。可以用HARQ发送分组的一个或多个传输，并且可以为分组发送ACK信息。可以发送分组，使得其可以在第一子帧（i）不可用于发送分组之前终止，或者（ii）可用于发送ACK信息。

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.
摘要翻译：描述了在无线网络中发送信息的技术。网络可以支持（i）用于发送单播信息的常规子帧和（ii）用于发送广播信息并且具有比常规子帧低的开销的多播/广播单频网络（MBSFN）子帧。在一方面，MBSFN子帧可以用于减轻干扰。第一基站可能对由第二基站服务的站（例如，UE）造成高干扰。第一基站可以为第二基站预留子帧，向其站发送传送保留子帧作为MBSFN子帧的系统信息，并根据MBSFN子帧格式在保留子帧的第一部分中进行发送。第二基站可以跳过第一部分，并且可以在保留的子帧的剩余部分中向其站发送单播信息。在另一方面，可以使用MBSFN子帧来支持附加的基站能力。

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, apparatuses, and methods are disclosed for a relay station (120) for use in a communication system with a base station (eNB) and user equipment (UE). The relay station may decode and forward a data packet between the base station and the UE that the relay station services in which the relay station does not establish a direct link with the UE. Further, the relay station indicates successful decoding of the data packet to the base station such that if the base station receives information indicating successful decoding of the data packet from the relay station, the base station terminates a HARQ transmission on a direct link between the base station and the UE such that HARQ retransmission time is extended compared to direct communications between the base station and the UE.

摘要： Techniques for using virtual noise figure for various functions in a wireless communication network are described. A virtual noise figure is an indication of a virtual noise level at a receiver, which may be higher than an actual noise level at the receiver. In an aspect, virtual noise figure may be used for serving base station selection. A terminal may receive information indicative of a virtual noise figure for each of at least one base station. The terminal may select a serving base station based on the virtual noise figure for each base station. The terminal may send data to the serving base station at a rate selected based on an actual noise figure for the serving base station. In other aspects, virtual noise figure may be used for interference management and/or power control.

摘要： Systems and methodologies are described that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell- specific reference signals (CRS), to improve hearability thereof for applications such as trilateration and/or the like. In particular, PRSs can be transmitted in designated or selected positioning sub frames. Resource elements within the positioning sub frame can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, potions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.

摘要： Systems and methodologies are described that facilitate indicating a dominant interferer to a target serving base station in a wireless communication environment. A mobile device can detect presence or absence of a dominant interferer. Further, an access probe that includes information related to the presence or absence of the dominant interferer can be generated. For example, the information can be included in a payload of the access probe as an explicit flag, an explicit indication of an interference level, a Channel Quality Indicator (CQI) value (e.g., reserved versus non-reserved,...), etc. Moreover, the access probe can be transmitted to the target serving base station to initiate an access procedure. The target serving base station can select a time-frequency resource to be utilized for a responsive downlink transmission (e.g., access grant signal, subsequent access related message,...) as a function of the information included in the access probe.

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.
