(EN) 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.

无线通信设备支持恒定发射功率操作模式以及随时间变化的发射功率操作模式以发送数据，例如对等点发现数据。该设备确定网络拥塞的量，并根据所确定的网络拥塞量在两种操作模式之间切换。所描述的各个方法和装置都很好地适用于对等自组织无线通信系统，在该系统中有限量的空中链路资源可用于对等点发现信令，并且相同的对等点发现资源有时会被多个设备同时使用。当网络拥塞较低时，设备操作在恒定发射功率模式下。当网络拥塞较高时，该设备操作在随时间变化的功率模式下。在本地区域内共享公共对等点发现资源的设备有意选择不同的随时间变化的传输模式。
