摘要： An improved mechanism is provided that facilitates transmission of small packets within an ad hoc peer-to-peer network. A small packet is identified to a receiver within a control channel so that its lower power can be considered in an interference management protocol implemented among local peer devices. In a traffic slot, a transmitter voluntarily backs down on the transmitter power as a smaller packet will require much lower signal-to-noise ratio. This will improve the signal energy per bit per noise power density for the transmission as well as minimize the interference caused to other wireless communications happening in the same spectrum.
摘要翻译：提供了一种改进的机制，其有助于传送自组织对等网络内的小分组。对于控制信道内的接收机识别出小分组，使得在本地对等设备之间实现的干扰管理协议中可以考虑其较低的功率。在业务时隙中，发射机主动地对发射机功率进行备份，因为较小的分组将需要较低的信噪比。这将改善传输中每比特每信噪比功率密度的信号能量，并最大限度地减少对同一频谱中发生的其他无线通信的干扰。

摘要： Apparatus and method are provided for generating transmission connection identifiers (CIDs) in a non-orthogonal or pseudo-random manner identifying peer-to-peer connections in a wireless communication network. When a transmitter terminal intends to transmit to its peer receiver terminal, it just picks a transmission CID in a pseudo-random manner, without trying to avoid a similar transmission CID in a neighborhood. The method of generating this pseudo-random transmission CID may be agreed to between the transmitter and its intended receiver beforehand, for example, during the paging cycle. Also, the mapping between the transmission CID and a set of tone/symbols may not necessarily be orthogonal. In one embodiment, the transmission CID may also change over time in a pseudo-random fashion which is different between different transmitter/receiver pairs. With this property, two transmitter/receiver (Tx/Rx) pairs are not likely to use the same transmission CID for consecutive time intervals.

摘要： A first device is configured to select and utilize a connection identifier (CID) for a peer-to-peer communication connection between the first device and a second device in a wireless communications network. The CID is selected from a predetermined set of a plurality of CIDs. Prior to selecting the connection identifier, the first device monitors a CID broadcast channel to determine whether the CID is being utilized by other nearby connections. If it is determined that the CID is being utilized by another connection in the proximity, a different (unused) CID is selected. A transmission request is transmitted to the second device using a first transmission resource unit within a traffic management channel slot, the first transmission resource unit being determined as a function of the selected CID. The first device transmits traffic data to the second device in a traffic channel slot corresponding to the traffic management channel slot.

摘要： Wireless terminals in a peer to peer system, which desire to communicate traffic signals, acquire a connection identifier associated with traffic transmission request air link resources. The air link resources in the system, in some embodiments, are structured so that each connection identifier has a one to one mapping to a request transmission unit, the request transmission units are arranged into a plurality of groups, and each group occurs in a different symbol time interval for the same traffic slot. A wireless terminal identifies locally available connection identifiers from a set of connection identifiers based on power received on individual connection identification transmission units in a set of connection identification transmission units; determines, for each group having an identified locally available connection identifier, an interference estimate; and selects a connection identifier from the identified locally available connection identifiers belonging to a group having an acceptable determined interference estimate.

摘要： Methods and apparatus related to broadcasting data and interference management in a peer to peer wireless communications network are described. Scheduling of traffic air link resources is performed on a slot by slot basis in a decentralized manner. Wireless devices intending to broadcast traffic signals transmit broadcast request signals, sometimes alternatively referred to as broadcast indicator signals. A priority level is associated with each of the broadcast request signals. A receiver device intending to receive broadcast signals detects the broadcast request signals and makes an interference determination as to whether the higher priority broadcast traffic signal can be successfully recovered in the presence of lower priority broadcast traffic signals. If the determination is that the expected interference from the lower priority broadcast traffic is unacceptable, the receiver device generates and transmits an interference control signal communicating to the lower priority device a command or request not to broadcast.

摘要： Methods and apparatus related to the communication of traffic in peer to peer communications are described. A peer to peer communications system includes traffic slots, and for a pair of devices (first and second) having a connection a first transmission request resource and a second transmission request resource are associated with a traffic transmission interval of the traffic slot, the first request resource preceding the second request resource. The first device can utilize the first resource to transmit a request to transmit traffic to the second device, and when it does, it also uses the second resource to transmit additional information corresponding to the request and/or traffic. If the second device doesn't detect a request on the first resource, then it can use the second resource to transmit a request to first device to transmit traffic to the first device.

摘要： Methods and apparatus related to scheduling and/or utilization of air link traffic resources are described. A connection identifier is associated with priority with regard to use of an air link resource, e.g., a peer to peer traffic segment which is in contention. A particular connection may acquire and hold one or multiple connection identifiers. In some embodiments, the priority associated with a particular connection identifier is intentionally varied in a set of traffic slots. In some such embodiments, there is priority randomization from slot to slot. In one such implementation there is a statistically uniform average priority between the different connection identifiers over the recurring structure. Such an implementation facilitates access to traffic segments to a wide range of users, yet allows for differentiation with regard to the amount of access as a function of the number of connection identifiers being held by a particular connection.
摘要翻译：描述与空中链路业务资源的调度和/或利用相关的方法和装置。关于使用空中链路资源（例如，竞争中的对等业务段），连接标识符与优先级相关联。特定连接可以获取和保存一个或多个连接标识符。在一些实施例中，与特定连接标识符相关联的优先级有意在一组业务时隙中变化。在一些这样的实施例中，存在从时隙到时隙的优先随机化。在一个这样的实现中，在重复结构上，在不同的连接标识符之间具有统计上均匀的平均优先级。这样的实现便于对广泛的用户访问业务段，但是允许根据由特定连接持有的连接标识符的数量的访问量的差异。

摘要： Methods and apparatus well suited for supporting communications over different ranges in, for example, a peer to peer wireless communications system, are described. In the peer to peer network at least some of the types of signals, e.g., peer discovery signals and/or paging signals, are transmitted with no closed loop power control. An exemplary peer to peer timing structure includes air link resources allocated for a particular type of signaling in which the resources are segmented into multiple blocks which do not overlap in time, different ones of the multiple blocks being associated with different ranges. The characteristics of the basic transmission units of the multiple blocks based on range are different, e.g., tone size and symbol width are different. A wireless communications device implements the peer to peer timing structure and uses resources from different range based blocks at different times. Data traffic transmission units may be the same regardless of the range.

摘要： Methods and apparatus well suited to decentralized traffic scheduling in wireless peer to peer network are described. An individual wireless terminal corresponding to a peer to peer connection makes a transmitter yielding or receiver yielding decision for a traffic slot. Quality of service information is disseminated as part of the scheduling control signaling. A scheduling control signal, e.g., a traffic transmission request signal or a traffic transmission request response signal, includes a pilot portion and a quality of service information portion. The pilot facilitates the recovery of the quality of service information by a plurality of different devices which may have different channel conditions with respect to the transmitter of the scheduling control signal. The different devices may benefit from utilizing the recovered quality of service information in making a yielding decision regarding traffic signaling in a traffic segment.
