摘要： Paging congestion control in a wireless communications system is described. Various described methods and apparatus are well suited for use in a peer to peer wireless communications system, e.g., an ad hoc peer to peer wireless network in which decisions are made in a decentralized manner. Wireless terminals, e.g., mobile nodes, monitor other paging activities going on and make back-off, e.g., yielding, decisions with regard to paging based on the results of the monitoring. During a first time interval paging indicator signals are transmitted on paging indicator resources by devices intending to transmit paging signals. During a second time interval paging signals are transmitted on paging signaling resources. Monitored and processed detected paging indicator signals are used by a wireless terminal in deciding whether or not to transmit a paging indicator signal and/or a paging signal.

摘要： A method, a computer program product, and an apparatus are provided. In one configuration, the apparatus transmits a first broadcast signal including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus transmits a second broadcast signal in the unicast resource. In another configuration, the apparatus, which is a first wireless device, receives a first broadcast signal from a second wireless device including information indicating an intention to use a unicast resource for a broadcast. 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.

摘要： Techniques for transmitting signals on shared resources in a manner to detect and/or combat collision are described. In an aspect, a terminal may transmit a signal on a subset of resource elements in a resource block, and at least one null resource element with no signal may be used to detect for collision of the signal. In another aspect, different terminals may simultaneously transmit their signals on different subsets of resource elements in a resource block. These different subsets of resource elements may be pseudo-randomly selected to randomize interference. In one design, a terminal may determine a resource block to use for transmission of a signal, select a subset of the resource elements in the resource block, and transmit the signal on the selected resource elements, e.g., to at least one other terminal for peer-to-peer communication. The signal may be a peer discovery signal, a paging signal, etc.

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 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：传输启动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启动间隔之外。在一些实施例中，分组传输长度被有意地限制为可以在物理层允许单个设备连续发送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感测技术的情况下，多个设备将能够以短时间间隔成功地发送小分组的概率。
