Abstract: Techniques for sending resource requests in a wireless communication system are described. Multiple types of quality of service (QoS) information may be supported for resource requests and may include QoS class and latency deadline. A terminal may have data to send on the reverse link and may determine QoS information for the data. The QoS information may include at least one QoS type, which may be dependent on a configuration selected for use to send resource requests. The terminal may also determine backlog level information indicative of the amount of data to send. The terminal may generate a resource request with the backlog level and QoS information. The resource request may include the backlog level information and QoS class information, the backlog level information and either QoS class information or latency deadline information, the backlog level information and latency deadline information, or some other combination of information.

Abstract: Methods and apparatus for communicating packets from a remote access node assembly by way of a serving access node assembly are described. An inter-route tunneling protocol module which interfaces with a radio link protocol module is used to recover a tunneled route protocol packet. Information to be communicated to the access terminal from the remote access node assembly by way of the serving access node assembly is subject to two levels of radio link protocol (RLP) processing operations. The first level of RLP processing being performed by the remote access node assembly. The second level of RLP processing being performed by the serving access node assembly. The access terminal, in recovering information performs the inverse of the two levels of RLP processing.

Abstract: Systems and methods are provided for processing wireless signal components for a mobile wireless access broadband service. This can include processes for measuring signal strength of an alternative frequency by tuning away from an existing frequency associated with an existing communications path. Such processes allow determining if the alternative frequency supports a subsequent communications path in a mobile broadband wireless application. Upon the determination, the process can automatically select the subsequent communications path based in part on the measured signal strength.

Abstract: Techniques to transmit pilot on a CDMA segment on the reverse link in a wireless communication system are described. A terminal generates a scrambling sequence based on its pilot information. The pilot information may be used for the entire duration of a call by the terminal and for all sectors with which the terminal communicates during the call. The terminal generates pilot symbols based on the scrambling sequence, maps the pilot symbols to the CDMA segment, generates OFDM symbols with the mapped pilot symbols, and sends the OFDM symbols to one or more sectors. A base station processes received OFDM symbols to obtain received symbols for the CDMA segment. The base station generates the scrambling sequence based on the pilot information for the terminal and processes the received symbols with the scrambling sequence to obtain at least one parameter (e.g., received signal strength) for the terminal.

Abstract: Methods and apparatus for communicating between an access terminal (AT) and remote device via an access point (AP) are described. For communications over the air link, between an AP and an AT a short address corresponding to the remote device is used for routing packets to/from the remote device. This conserves air link resources. However, for communicating between the AP and the remote device a longer address, e.g., a full IP address corresponding to the remote device is used. The AT converts between the long and short addresses as information, e.g., packets are communicated between the remote device and the AT. The long address may be, for example, an IP address corresponding to the remote device used to route packets through a Layer 2 tunnel between the remote device and the AP. In some embodiments the remote device is a remote access point.

Abstract: Methods and apparatus for tunneling packets between remote and serving Access points for delivery to an access terminal (AT) are described. Methods and apparatus for communicating control values and/or information in addition to information to be delivered to an AT over an airlink are also described. An AT uses the received control information to recover communicated packets. Some features support the use of various headers and/or indicators in the headers, e.g., RLP and/or Packet Correlation Protocol (PCP) headers, which may be used to control routing of communicated payloads to an RLP processing module corresponding to an AP which was the source of the communicated payload.

Abstract: Systems and methods are described that facilitate data communication in a wireless communication environment. According to various aspects, a node, such as an access point or an access terminal, may determine a number of channels over which it will transmit a communication signal. The node may then select channels based on whether the channels are available or unavailable, wherein available channels are preferentially selected over unavailable channels. The node may then transmit a signal over the at least one of the selected channels.
