    摘要: Techniques for sending and receiving signaling in a wireless communication system are described. Multiple (e.g., eight) vectors of modulation symbols may be defined and may be orthogonal to one another. Multiple subscriber stations may share transmission resources and may simultaneously send different vectors of modulation symbols in the same tile. Each subscriber station may be assigned multiple sets of at least one vector of modulation symbols usable by that subscriber station to convey signaling, e.g., one set of three vectors for acknowledgement (ACK) and another set of three vectors for negative acknowledgement (NAK). Each subscriber station may send one set of at least one vector in at least one tile to convey a signaling value. Different subscriber stations may simultaneously send different sets of at least one vector in the at least one tile to convey their signaling values.

    摘要: A method and apparatus are for communication in a wireless network in which a User Equipment (UE) associated with a first evolved Node B (eNB) experiences interference from a second eNB. The method includes negotiating by the first eNB of the wireless network with a second eNB of the wireless network for a partitioning of subband resources on an uplink. A first subset of subband resources is assigned to the first eNB, and a second subset of subband resources is assigned to the second eNB. A method and apparatus are for communication in a wireless network. The method includes decoding a downlink control channel received during a protected downlink subframe to determine an uplink subframe n containing a protected subband for uplink transmission. The method also includes transmitting data during the uplink subframe n on the protected subband.

    摘要: A method for power control in a long term evolution (LTE) network is disclosed and includes configuring a user equipment (UE) with a plurality of transmit power levels where each transmit power level corresponds to a subframe type. A first power level is used in subframes protected by cooperative coordination between base stations. A second power level corresponds to unprotected subframes. The method also includes scheduling the UE to transmit in accordance with the configured transmit power levels.

    摘要: To avoid or reduce intra-cell interference, each sector of a cell is associated with a sector-specific set of system resources (e.g., subbands) and at least one non-overlapping common set of system resources. Each common set for each sector includes system resources observing little or no interference from at least one other sector in the cell. The channel condition for a terminal in a given sector x is ascertained based on forward and/or reverse link measurements for the terminal. The terminal is assigned system resources from a common set or a sector-specific set for sector x based on the terminal's channel condition. For example, if the terminal observes high interference from another sector y, then the terminal is assigned system resources from a common set that observes little or no interference from sector y. The techniques may be used for an OFDMA system that uses frequency hopping.

    摘要: Techniques for sending control information are described. In an aspect, information to send in a control message may be fragmented into multiple parts, with each part including information of a particular type. The multiple parts may be segregated into multiple categories such as dynamic, semi-static, and static. A full message containing all parts may be generated and sent at a first rate. A first partial message containing parts in the dynamic category may be generated and sent at a highest rate. A second partial message containing parts in the semi-static category may be generated and sent at a second rate that is slower than the highest rate. A third partial message containing parts in the static category may be generated and sent at a third rate that is slower than the second rate.

    摘要: For range expansion, a determination to enter range expansion may be made based on a signal strength differential for user equipment (UE) communications between a first class of base stations and a second class of base stations. If the signal strength differential is beyond a certain threshold, range expansion may be implemented. In range expansion, a signal is transmitted, on a resource coordinated with at least one of the first class of base stations, from one of the second class of base stations to the UE which could experience dominant interference from one of the first class of base stations if coordination were not performed. Transmission power may be reduced from one of the first class of base stations on that resource. The second signal may be transmitted within the region of the Physical Downlink Shared Channel.

    摘要: Information is transmitted over selected, Orthogonal Frequency Division Multiplexed (OFDM) sub-channels to avoid frequencies with unacceptable congestion, noise or interference levels. Using frequency hopping, selected non-contiguous OFDM sub-channels used for transmission may vary with time. Once a group of OFDM sub-channels is selected, a power level and modulation technique may also be selected based on channel quality.
