The invention discloses a live broadcast interaction method and device and a storage medium, and belongs to the technical field of Internet. The method comprises the following steps: the first anchorend sends a live broadcast interaction request to the server, the server determines identifiers of N second anchors to be in live broadcast interaction with the first anchor based on a live broadcastinteraction request sent by a first anchor end., sends a live broadcast interaction response message to the first anchor end, and then, the first anchor end obtains the live broadcast score of the first anchor and the live broadcast score of each second anchor in the N second anchors, and displays the live broadcast score of the first anchor and the live broadcast scores of the N second anchors ina live broadcast interface of the first anchor to realize live broadcast interaction. The first anchor and other anchors can perform live broadcast interaction based on the respective live broadcastscores, and the server does not need to transmit the audio and video data packet between the anchor ends in the live broadcast interaction period, so that the load of the server can be greatly reduced, and the cost requirement on the server is reduced.

Methods and apparatus of channel feedback are disclosed. In OFDM systems, the channel is acquired in the frequency domain. A generic multipath model for wireless channels, however, reveals that the time-domain parameters of the channel require much smaller data than the frequency-domain representation of the channel. Means to extracting the time-domain parameters from the frequency-domain channel samples are described for both the continuous time domain and the discrete time domain. Refinements of the time-domain parameters via minimizing a frequency-domain matching error are also described, which further improve the quality of the channel feedback and reduce the feedback overhead. Channel feedback with the time-domain parameters requires only a small fraction of the feedback overhead that is needed by existing channel feedback schemes, and maintains consistently superior performances over wireless channels of various delay spreads, short or long.
