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： 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).

摘要： Systems and methodologies are described that facilitate utilizing power-based rate signaling for uplink scheduling in a wireless communications system. A maximum nominal power (e.g., relative maximum transmit power that may be employed on an uplink) may be known to both a base station and a mobile device. For example, the base station and the mobile device may agree upon a maximum nominal power. According to another example, signaling related to a maximum nominal power for utilization on the uplink may be provided over a downlink. Further, selection of a code rate, modulation scheme, and the like for the uplink may be effectuated by a mobile device as a function of the maximum nominal power. Moreover, such selection may be based at least in part upon an interference cost, which may be evaluated by the mobile device.

摘要： Wireless terminal for use with a multi-mode base station that supports a transmit standby mode and an active mode is described. Transmit standby mode of base station operation is a low power/low interference level of operation as compared to active mode. In transmit standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. In transmit standby mode, the base station has no active state registered wireless terminals being serviced but may have some sleep state registered wireless terminals being serviced. Mode transitions from active to transmit standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmit standby to active may be in response to: scheduling information, access signals, wake-up signals from the wireless terminal, hand-off signals, etc.

摘要： Techniques for sending control messages are described. In an aspect, assignment messages may be acknowledged based on either linked or dedicated acknowledgement (ACK) resources. A terminal may receive an assignment message from a base station, determine whether to acknowledge the assignment message, and determine ACK resources to use to acknowledge the assignment message. The ACK resources may be linked to a control block on which the assignment message was received, linked to resources given by the assignment message, or assigned to the terminal. The terminal may send the acknowledgement on the ACK resources. In another aspect, a control message may be acknowledged based on ACK resources determined based on the control message or the control block. The ACK resources may be linked to resources assigned by the control message or linked to the control message. The terminal may send an acknowledgement for the control message on the ACK resources.
