    Abstract: An explicit indication is provided regarding whether information was subjected to interference during transmission. For example, a receiver can monitor received packets and determine whether any of data units in a given received packet were subjected to interference during transmission. If so, the receiver can send an indication to the transmitter to inform the transmitter of the interference. This indication enables the transmitter to distinguish between packet loss that occurred as a result of channel fade and packet loss that occurred as a result of interference. Consequently, the transmitter is able to invoke different actions depending on whether the packet loss is due to channel fade or interference.

    Abstract translation: 提供关于在传输期间信息是否受到干扰的明确指示。 例如，接收机可以监视所接收的分组，并且确定给定的接收分组中的任何一个数据单元是否在传输期间受到干扰。 如果是这样，接收机可以向发射机发送指示以通知发射机的干扰。 该指示使得发射机能够区分由于干扰而导致的由于信道衰落和分组丢失而导致的分组丢失。 因此，发射机能够根据信道衰落或干扰造成分组丢失来调用不同的动作。

    Abstract: Methods and apparatus related to selecting and/or using different coding methods for a broadcast channel are described. The coding method to be used is selected as a function of an estimated level of congestion. Various methods and apparatus are well suited for use in peer to peer wireless communications systems including broadcast peer discovery channels. A wireless communications device, e.g., a mobile terminal supporting peer to peer signaling, detects peer discovery signals from other devices and estimates a level of congestion. The wireless communications device selects one of a plurality of alternative coding methods as a function of the estimated level of congestion. Two different coding methods which may be used, in some embodiments, vary in at least one of: coding rate, convolution code used, and amount of resources used. The wireless device transmits information indicating the selected coding method and coded peer discovery data in accordance with the selected coding method.
