摘要： Methods and apparatus for determining, e.g., selecting, communications resources, e.g., tones, to use in a communications system are described. The methods are well suited for use in Orthogonal Frequency Division Multiplexing (OFDM) systems. Devices seeking to transmit information select tones in pairs for use in transmitting the information. Each tone pair includes a tone and the corresponding image tone. By restricting a communications device to select communications frequencies in pairs, the problem of interference and reduced dynamic range at a receiver due to IQ imbalance is reduced, as compared to the case where devices may use a tone independent of the corresponding image tone for transmission purposes, since the path loss from the transmitter to the receiver is likely to be the same for both tones and the transmission power level is controlled by an individual device using both of the tones.
摘要翻译：描述了用于确定例如选择在通信系统中使用的通信资源，例如音调的方法和装置。该方法非常适用于正交频分复用（OFDM）系统。寻求发送信息的设备成对选择音调以用于发送信息。每个音色对包括一个音调和相应的图像色调。通过限制通信设备成对地选择通信频率，与设备可以使用独立于对应的图像色调的音调以用于传输目的的情况相比，由于IQ不平衡而导致的接收机的干扰和减小的动态范围的问题减少了，因为从发射机到接收机的路径损耗对于两个音调可能是相同的，并且发射功率电平由使用两个音调的单个设备控制。

摘要： A transmission initiation interval timing structure is used in combination with a lower layer timing structure, e.g., physical layer timing structure. A device selects a subset of packet transmission initiation intervals and then limits initiation of packet transmission to those intervals thereby reducing the potential for collisions. Packet transmission may occur outside the initiation interval in which the transmission is initiated. In some embodiments, packet transmission length is intentionally limited to sizes which can be transmitted in a fraction of the amount of time the physical layer allows a single device to continuously transmit, e.g., in an amount of time which is equal to or less than the duration of a packet transmission initiation interval. This increases the probability that multiple devices will be able to successfully transmit small packets at short intervals on a regular basis even when carrier sensing techniques are used.
摘要翻译：传输起始间隔定时结构与较低层定时结构结合使用，例如物理层定时结构。设备选择分组传输启动间隔的子集，然后限制分组传输的开始到那些间隔，从而减少冲突的可能性。分组传输可能发生在传输启动的发起间隔之外。在一些实施例中，分组传输长度被有意地限于可以在物理层允许单个设备连续传输的时间量的一小部分中传输的大小，例如，等于或小于分组传输启动间隔的持续时间。这增加了即使在使用载波侦听技术的情况下，多个设备也能够以短时间间隔成功传输小数据包的概率。

摘要： A method, a computer program product, and an apparatus for wireless communication are provided. The apparatus transmits a first peer discovery signal with a first periodicity/temporal frequency in a first set of peer discovery resources. The apparatus determines an energy on an allocated peer discovery resource of a second set of peer discovery resources. The apparatus refrains from transmitting a second peer discovery signal in the second set of peer discovery resources when the energy is greater than a threshold. The apparatus transmits the second peer discovery signal in the second set of peer discovery resources with a second periodicity/temporal frequency less than the first periodicity/temporal frequency when the energy is less than the threshold. The apparatus may utilize the first set of peer discovery resources every period and the second set of peer discovery resources once every N periods in which once every N periods is the second periodicity.

摘要： A wireless communications device supports a constant transmission power mode of operation and a time varying transmission power mode of operation for transmitting data, e.g., peer discovery data. The device determines an amount of network congestion and switches between the two modes of operation as a function of the determined amount of network congestion. Various described methods and apparatus are well suited for use in a peer to peer ad hoc wireless communications system in which a limited amount of air link resources are available for peer discovery signaling and the same peer discovery resources are, at times, used concurrently by multiple devices. When network congestion is low, the device operates in the constant transmission power mode. When network congestion is high, the device operates in the time varying power mode. Devices sharing a common peer discovery resource in a local area intentionally select different time varying transmission patterns.

摘要： Methods and apparatus for allocating traffic contention resource units in a wireless communications system in which decisions are made in a distributed manner are described. A wireless communications device, corresponding to a link, self allocates resource units for traffic contention. Decisions regarding initially acquiring resources, relinquishing acquired resources, and/or acquiring additional resources for traffic contention are based on detected levels of network congestion and/or detected changes in network congestion. A wireless communications device detects a level of network congestion and determines a number of resource units to acquire for traffic contention based on the detected level of network congestion.

摘要： Methods and apparatus for use in a wireless system are described where initiation of packet transmission is constrained in accordance to control actual packet transmission in a manner that reduces contention and possible collisions beyond that provided by lower layer resource contention mechanisms, e.g., 802.11 carrier sensing and/or transmission back-off timing mechanisms. Through higher level, e.g., MAC constraints, on packet transmission initiation, an air interface which employs carrier sensing can be used and controlled in a manner which reduces collisions and interference in applications where small packets, e.g., packets which can be transmitted in a fraction of the maximum permitted transmission time. The methods allow small packets in such systems to be transmitted on a periodic or semi-periodic basis in many cases.

In addition, the apparatus receives a first scheduling signal from the second wireless device in a scheduling resource. The first scheduling signal is for indicating a second intention to use the unicast resource for transmitting a second broadcast signal. Furthermore, the apparatus refrains from transmitting a second scheduling signal in the scheduling resource in response to the first scheduling signal.
