Transmission by a first node may be controlled based on a status of a second node. The status of the second node may indicate, for example, whether the second node will be communicating with the first node. Thus, if it is determined based on the status of the second node that the second node may not be communicating with the first node, transmissions by the first node may be temporarily disabled until there is a change in status, and vice versa.

Methods and apparatus are described for transmitting information units over a plurality of constant bit rate communication channel. The techniques include encoding the information units, thereby creating a plurality of data packets. The encoding is constrained such that the data packet sizes match physical layer packet sizes of the communication channel. The information units may include a variable bit rate data stream, multimedia data, video data, and audio data. The communication channels include CMDA channels, WCDMA, GSM channels, GPRS channels, and EDGE channels.

Delivery of information over a communication channel

Various aspects of the invention provide for determining data rate for a reverse link communication by determining packets of data for transmission for a number of communication services, determining a data rate for transmission of the packets of data based on an arrangement of the packets of data in a queue allowing for meeting the transmission deadline for each of the packets of data. The base station determines whether available resources allow for allocation at the base station for transmission from the mobile station at the determined data rate and duration. The mobile station drops at least a packet of data of the packets of data in the queue to determine a new queue of packets of data. The new queue of the packets of data is used to determine a new data rate for communication on the reverse link.

Embodiments for bandwidth allocation methods, detecting interference with other systems, and/or redeploying in alternate bandwidth are described. Higher bandwidth channels may be deployed at channel boundaries (), which are a subset of those for lower bandwidth channels (), and may be restricted from overlapping. Interference may be detected () on primary, secondary, or a combination of channels, and may be detected in response to energy measurements () of the various channels. When interference is detected, a higher bandwidth Basic Service Set (BSS)() may be relocated to an alternate channel, or may have its bandwidth reduced to avoid interference. Interference may be detected based on energy measured on the primary or secondary channel, and/or a difference between the two. An FFT () may be used in energy measurement in either or both of the primary and secondary channels. Stations may also monitor messages from alternate systems to make channel allocation decisions. Various other aspects are also presented.

Techniques for controlling transmissions in wireless communication networks are described. In one aspect, transmission control for a mesh network may be achieved by ranking mesh points or stations in the mesh network. In one design, the rank of a first station in the mesh network may be determined. At least one station of lower rank than the first station in the mesh network may be identified. At least one transmission parameter for the at least one station of lower rank may be set by the first station. At least one transmission parameter value may be selected for each station based on the rank, QoS requirements, amount of traffic, and/or achievable data rate for that station and may be sent (e.g., via a probe response message) to the station.

Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.
