Abstract: In an audio network system constructed from a main node and a plurality of satellite nodes each having a plurality of ports, the main node generates and transmits a main packet including audio signals of a plurality of channels. Each satellite node selects one of the plurality of ports in turn, and confirms whether the main packet arrives at the selected port every predetermined period or not. When the main packet arrives at the selected port every predetermined period, the main packet is received via the port by continuing selection of the port. In the case where reception of the main packet is lost, one is selected from the plurality of ports in turn, the operation to confirm arrival of the main packet is restarted, and another port at which the main packet arrives at the present stage is automatically found.

Abstract: When using a multi-receiver aggregation protocol in a wireless communications network, a sub-header may be used to identify groups of data units that share common parameters, such as destination addresses, acknowledgement modes, modulation/coding rates, lengths, etc. The layout of this sub-header may permit each receiving device to identify the portion of the aggregated payload that is addressed to that receiving device, where that portion is located, how long that portion is, and how to demodulate it. In addition, by controlling the selection and timing of various acknowledgement modes used by the mobile stations, a base station may improve overall network efficiency and throughput.

Abstract: Technologies are generally described for quiet period management in secondary opportunistic networks. Access Points (APs) in close proximity may form an ad hoc network (e.g., IEEE 802.11af) and instead of sensing and detecting idle channels in TV white spaces, listen to the broadcast messages from a co-existence manager, which broadcasts periodic intraframe sensing (IRFS) and interframe sensing (IFS) information in Medium Access Control (MAC) packets. The APs may extract information regarding the operating channels of the active cognitive base stations and their scheduled IRFS and IFSs on these channels. According to one scheme, short IRFS intervals over active channels may be allocated in a dedicated manner using a unique access request packet (ARP) by emergency network APs. According to another scheme, contention-based access may be provided to longer IFS intervals on multiple channels.
