Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies for performing adjustments for interference management and delta-based power control in a wireless communication system.SOLUTION: A terminal can utilize one or more delta-based power control techniques upon engaging in a reverse link transmission after a predetermined period of silence or after receiving indications of interference from neighboring access points. A delta value can be computed (506) through open-loop projection, on the basis of which transmission resources such as bandwidth and/or transmit power can be increased or decreased (508) to manage interference caused by the terminal. A delta value can also be communicated as feedback to a serving access point to allow the access point to assign transmission resources for the terminal.

Abstract: PROBLEM TO BE SOLVED: To provide a method of dynamically managed operation of network resources in a wireless communication system by utilizing reserved de-assignment resources.SOLUTION: An access point determines whether to de-assign one or more resources assigned to an access terminal for at least two frames. If de-assignment is determined, the access point generates a message indicative of a request to de-assign the resources, and transmits the message on a reserved de-assignment channel. Among four states, namely, an off state indicative of NACK and no de-assignment, an acknowledge state indicative of ACK and no de-assignment, an acknowledge and de-assign state indicative of ACK and de-assignment, and a de-assign state indicative of NACK and de-assignment, the message indicative of the request to de-assign the resources has the acknowledge and de-assign state or the de-assign state.

Abstract: PROBLEM TO BE SOLVED: To perform electric power control over a plurality of channels transmitted using a plurality of radio techniques.SOLUTION: Transmission electric power of a reference channel transmitted using a first radio technique (for example, CDMA) is adjusted so as to attain a target level (for example, a target rate of disappearance) of performance of the reference channel. Transmission electric power of a data channel transmitted using a second radio technique (for example, OFDMA) is adjusted based upon the transmission electric power of the reference channel. One electric power control mechanism determines a reference electric power spectrum density (PSD) level on the basis of the transmission electric power of the reference channel. Transmission PSD delta of the data channel is adjusted through interference estimation. Transmission PSD of the data channel is determined based upon the reference PSD level and the transmission PSD delta. Then the transmission electric power of the data channel is set so as to attain the transmission PSD of the data channel.

Abstract: PROBLEM TO BE SOLVED: To facilitate management of interference and communication resources.SOLUTION: A differential approach is provided in which other-sector interference (OSI) and communication resources are managed by adjusting an offset (delta) value associated with the resources in response to receiving an indication of other-sector interference. An OSI indication is issued based on a short time scale and a long time scale, and effective interference metrics over time-frequency resources. The adjusted delta value is communicated to a serving access point, which reassigns communication resources in order to mitigate other-sector interference.

Abstract: PROBLEM TO BE SOLVED: To facilitate establishing a forward link acknowledgement channel and transmitting acknowledgment signals thereupon.SOLUTION: The signals are spread within contiguous channel clusters in a tile where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassign value, which provides diversity for devices to utilize persistent channels in communicating data to one another.

Abstract: PROBLEM TO BE SOLVED: To facilitate communication of reverse link control information with OFDMA control channels and CDMA control channels.SOLUTION: Dedicated OFDMA control channel resources can be assigned to a mobile device. Control information related to one or more logical control channels can be generated by the mobile device.

Abstract: PROBLEM TO BE SOLVED: To provide techniques for efficiently sending control information.SOLUTION: A plurality of control resources are defined and mapped to transmission units for a control segment. For symmetric mapping, multiple sets of control resources are formed, and each batch of L consecutive sets of S control resources is mapped to S transmission units at the same location in the L tiles. For localized mapping, each set of S control resources is mapped to a cluster of S adjacent transmission units in one tile. For distributed mapping, each control resource is mapped to one transmission unit in one tile. For diversity, each control resource is mapped to multiple (e.g., three) transmission units in at least one tile.
