    Abstract: PROBLEM TO BE SOLVED: To provide a rate prediction in a fractional reuse system. SOLUTION: The apparatus and method intended to provide rate prediction is an apparatus and method for rate prediction in a wireless communication system involving fractional frequency reuse. A wireless communication system implementing Orthogonal Frequency Division Multiple Access (OFDMA) implements a fractional frequency reuse plan, in which a fraction of a carrier is allocated to a terminal having no possibility of handoff and another fraction of the carrier is reserved for a terminal having a higher possibility of handoff. The fractions respectively define a reuse set. The terminal is constrained to frequency hop within a reuse set. The terminal is also configured to determine a reuse set based on a present assignment in a subset of the carrier. The terminal determines a channel estimate and a channel quality indicator partially based on at least the present reuse set. The terminal reports the channel quality indicator to a source, which determines a rate based on the index value. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To receive control information while mitigating interference from other transmitters.SOLUTION: The interference is mitigated by wireless network transmitters blanking or reducing power on a portion of bandwidth reserved for control information transmission. The control information portion is divided into a plurality of OFDM tiles that are reusable by the transmitters for transmitting the control information. The transmitters multiplex the control information over the plurality of tiles to increase the probability that at least a portion of the tiles are not interfered, thereby further mitigating the interference between the transmitters. Receivers decode the control information from the portion of tiles with a low probability of the interference.

    Abstract: PROBLEM TO BE SOLVED: To assign resources corresponding to discontinuous portions of bandwidth.SOLUTION: A single assignment may be used to assign multiple disjoint portions of bandwidth to be used by a wireless terminal at the same time as an uplink or downlink band. Different portions of bandwidth allocated to a terminal may have different numbers and/or locations of guard subcarriers with relevant guard subcarrier information being communicated to the wireless terminal in a broadcast signal or being determined from stored information. The disjoint portions of bandwidth allocated for use to a terminal may be separated by a carrier band, e.g., 1.25 MHz or more, which is not available for use because it is owned by another service provider. Some embodiments are implemented using OFDM signals where a wireless terminal may generate or receive a symbol including subcarriers (tones) corresponding to the different discontinuous portions but not the bandwidth separating the discontinuous portions.

    Abstract: PROBLEM TO BE SOLVED: To support efficient operation by a terminal in an idle state.SOLUTION: A base station transmits a preamble periodically in each superframe. The preamble includes at least one first OFDM symbol for control information and subsequent at least one second OFDM symbol for paging information. A terminal receives the first and second OFDM symbols and determines a receiver gain on the basis of the received power of the first OFDM symbol, e.g., with an AGC loop having a shorter time constant than the duration of the first OFDM symbol. The terminal processes the second OFDM symbol on the basis of the receiver gain to obtain the paging information. The terminal may operate in an idle state, determine superframes assigned to the terminal, sleep between the assigned superframes, and process the first and second OFDM symbols in each assigned superframe to obtain the paging information.

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate serving sector directed transmit power control in a wireless communication environment.SOLUTION: Under certain conditions, an access point can have better data for determining more appropriate power levels than an individual terminal. Accordingly, an access point can transmit power control information to one or more terminals supported by the access point overriding normal power determination procedures. In particular, power control information can be included within an assignment message that designates resources (e.g., frequency, time) assigned to a terminal. Power control information can be based upon SNR, quality of service requirements, interference information, any other relevant information or any combination thereof.
