Abstract: The present disclosure proposes a method of a first node which is capable of using multiple wireless channels, wherein one or more of the channels are occupied by the first node for its current transmission to a second node, the method comprising: sending an indication to the second node, to indicate the second node to transmit towards the first node on the one or more occupied channels in the period between the current transmission and the continuing transmission of the first node; and listening on each of one or more other channels in the multiple wireless channels in the period for the continuing transmission. With this method, the power leakage from the occupied channel(s) will not impact the judgement of the listening of the first node on the other channel(s) in that period.

Abstract: A wireless media distribution system is provided comprising an access point (6) for broadcasting media and a plurality of stations (2) for reception and playback of media. Each station is configured for receiving and decoding a timestamp in a beacon frame transmitted repeatedly from the access point. This is used to control the output signal of a station physical layer clock (12) which is then used as a clock source for an application layer time synchronisation protocol. This application layer time synchronisation protocol can then be used in the station to control an operating system clock (8) for regulating playback of media.

Abstract: Embodiments of this application provide a data transmission method and apparatus. The data transmission method is applied to a network based on a CSMA/CA mechanism and the network includes a plurality of nodes that share one channel. According to the data transmission method, a sending node determines, in the plurality of nodes through a first clear channel assessment, that the channel is idle. The sending node then waits for a delay duration, and performs a second clear channel assessment on the channel after the delay duration. The sending node sends a data frame to a receiving node in the plurality of nodes through the channel in response to determining, through the second clear channel assessment, that the channel is idle. The sending node performs a clear channel assessment twice before sending a data frame, which reflects priorities of different types of data frames and shortens a network latency.

Abstract: A transmitting device (e.g., a base station, a user equipment (UE)) may pre-generate waveform components, for a transmission to be sent subsequent to a listen before talk (LBT) procedure, based on a waveform generation capability of the transmitting device (e.g., based on their memory storage capability, their ability to combine waveform components in the time domain following a per subband LBT procedure, etc.). Further, certain behavior or rules (e.g., which waveform components are generated, how many subbands are included in a waveform component, etc.) may be expected by both a base station and a UE depending on the waveform generation capability of the transmitting device and the resource allocation. Additionally, resource block group (RBG) configurations (e.g., RBG definitions) for improved resource allocation are also described. A bases station may indicate one or more guard band boundaries to a UE to indicate such RBG configurations that account for guard bands.
