Abstract: Various embodiments are described for a trained data transmission for communication systems. A training phase may include a first wireless station exchanging medium reservation messages with a second wireless station to reserve a medium and to select a data transmission parameter. The data transmission parameter may include a modulation scheme and a forward error correction (FEC) coding rate. At least one of the medium reservation messages may include a duration field indicating a duration for which the medium is reserved. A first data phase may include sending data from the first wireless station to the second wireless station according to the selected data transmission parameter. A second data phase may then be performed without first repeating the training phase. The second data phase may include transmitting data from the first wireless station to a second wireless station according to the data transmission parameter.

Abstract: A point coordinator in a wireless network, such as a wireless local area network (WLAN), may have the authority to control access to a channel by nodes in the network. The point coordinator may delegate the authority to a node in the network which requests access. The point coordinator may limit the extent of the delegation to a certain transaction or a predetermined amount of time.

Abstract: A method, apparatus and system for transmitting a data link descriptor or MAP signal describing sub-burst transmissions having a common number of resource units allocated thereto. The MAP signal may include the length of the common number of resource units allocated thereto and the modulation and coding schemes to be used thereby. A method, apparatus and system for transmitting an ordered MAP signal sequence describing a series of transmissions each having a number of resource units allocated thereto. A first plurality of locations in the ordered sequence may describe lengths of resource units. A second plurality of locations in the ordered sequence may describe numbers of transmissions having the lengths described in one of the first plurality of locations. A third plurality of locations in the ordered sequence may describe a number of transmissions using one of a plurality of modulation and coding schemes. Other embodiments are described and claimed.

Abstract: Briefly, a method of transmitting over a first wireless network a message not addressed to mobile units of the first wireless network, wherein receiving said message causes transmitting stations of the first wireless station to cease transmissions for a predetermined time interval and to enable the access point to be in communication with mobile units or access points of a second wireless network.

Abstract: Briefly, in accordance with one embodiment of the invention, an access point may preemptively broadcast an alternate channel to switch to, along with an indication of the beacon timing for the alternate channel, prior to any catastrophic interference. The access point may switch to the alternate channel in the event of interference on the original channel without attempting to broadcast the alternate channel during the interference event. A mobile user may then know in advance of the interference event which alternate channel the access point switched to and may switch to the alternate channel.

Abstract: Two separate radio frequency networks may be operated within interference distance from one another in a way which mitigates the possibility of interference. Using received signal strength indicator data, the nature of the interference may be determined without actually demodulating the interfering signal. The timing of the interfering signal and its characteristic features may be determined. Using that information, together with the probability that any given slot will actually be occupied by an interfering transmission, a statistics package may be developed which gives an indication of the probability of a transmission from the interferer at any given time. That package may be transmitted to other nodes in the same network. When a first node wishes to transmit information to a second node, the first node may analyze the statistics package received from the second node. The first node may thereby make a determination about when to actually initiate the transmission to the second node.

Abstract: A way of managing bandwidth in a network supporting variable bit rate is provided. An apparatus is provided that comprises an interface to transmit data to a receiving device. The apparatus comprises a controller that is communicatively coupled to the interface, the controller to detect a bit rate change event and transmit a first portion of the data using reserved bandwidth and a second portion of the data using unreserved bandwidth in response to detecting the bit rate change event.
