摘要： Systems and methodologies are described that facilitate communicating reverse link control information over OFDMA control channel(s) and CDMA control channel(s). Dedicated OFDMA control channel resources can be assigned to mobile device(s). Control information related to one or more logical control channels can be generated by a mobile device. Further, a physical control channel type (e.g., OFDMA control channel or a CDMA control channel) can be selected for sending the control information via the reverse link. For example, control information associated with periodic, logical control channels can be multiplexed and sent over the OFDMA control channel (e.g., utilizing the dedicated OFDMA control channel resources) while control information related to non-periodic, logical control channels can be transmitted over the CDMA control channel.

摘要： An uplink dedicated control channel reporting structure includes a plurality of different bit size reports, e.g. 1 bit, 3 bit and 4 bit reports, for reporting a wireless terminal's backlog information of uplink traffic request group queues. Smaller bit size reports are transmitted more frequently than larger reports. A 1 bit request report indicates whether or not there are any MAC frames of information to be communicated in a set of two request group queues. A 3 bit request report indicates an amount of backlog information corresponding to a first set of request group queues and a second set of request group queues. A 4 bit request report indicates an amount of backlog information corresponding to a set of request group queues. The 4 bit request report is capable of reporting information on any of a plurality of uplink traffic channel request group queues being maintained by the wireless terminal.

摘要： Wireless terminals and base stations support multiple modes of dedicated control channel operation wherein wireless terminals are allocated different amounts of dedicated uplink resources for reporting control information. A set of dedicated control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of dedicated control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the dedicated control channel segments associated with a single logical tone. In split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the dedicated control channel segments. Logical dedicated control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.

摘要： A wireless terminal measures the received power of a tone corresponding to an intention base station null output, measures the received power of pilot signals, and determines a signal to noise ratio of the received pilot signal. The wireless terminal calculates a downlink signal to noise ratio saturation level representative of the SNR of a received downlink signal that the wireless terminal would measure on a received signal transmitted by the base station at infinite power. The calculated downlink signal to noise ratio saturation level is a function of the determined interference power, the measured received pilot signal power, and the determined pilot signal SNR. A report is generated corresponding to one of a plurality of quantized levels, the selected quantized level being the closest representation to the calculated downlink signal to noise ratio saturation level. The generated report is communicated using a dedicated control channel segment in a predetermined uplink timing structure.

摘要： Methods and apparatus related to control information reporting over wireless communication channels are described. Various embodiments include communicating control information format definition information over a wireless link. For example, in some embodiments, a base station downloads control information reporting format definition information, e.g., corresponding to a new release or a custom reporting format, into a wireless terminal. As another example, a wireless terminal generates a custom control information reporting format, that it intends to use, and communicates definition information corresponding to the generated custom control reporting format to a base station.

摘要： Systems and methodologies are described that facilitate generating and/or analyzing downlink transmission units in OFDM TDD environments. Beacon signals may be selectively inserted within downlink transmission units; for example, the position of Beacon signals may vary from cell to cell. Further, the position may be a function of a characteristic of a cell (e.g., cell identifier) and/or an expected drift. Moreover, a Beacon signal may be interjected at a location in a downlink transmission unit so as to mitigate alignment with disparate Beacon signals in downlink transmission units associated with differing cells. Additionally, an identity of a cell providing downlink transmission units may be determined by analyzing a position of the Beacon signal within the downlink transmission units.

摘要： Systems and methodologies are described that facilitate scheduling uplink transmissions. For instance, a time sharing scheme can be utilized such that differing mobile devices can be scheduled to transmit during differing time slots; however, it is also contemplated that a static scheme can be employed. Pursuant to an illustration, an interference budget can be combined with a time varying weighting factor associated with a base station; the weighting factor can be predefined and/or adaptively adjusted (e.g., based upon a load balancing mechanism). Moreover, the weighted interference budget can be leveraged for selecting mobile devices for uplink transmission (e.g., based at least in part upon path loss ratios of the mobile devices). Further, disparate interference budgets can be utilized by differing channels of a sector at a particular time. Also, for example, a base station can assign a loading factor to be utilized by wireless terminal(s) for generating channel quality report(s).
