摘要： Techniques for controlling transmit power and the amount of overlapping in a quasi-orthogonal system are described. A base station for a sector receives transmissions from terminals in that sector and neighbor sectors and determines performance metrics (e.g., overall throughput) and/or QoS metrics (e.g., minimum data rate) for the terminals in the sector. The base station updates an overlapping factor based on the performance metrics and updates a QoS power control parameter based on the QoS metrics. The overlapping factor indicates the average number of overlapping transmissions sent simultaneously on each time-frequency block usable for data transmission. The QoS power control parameter ensures that the terminals in the sector can achieve minimum QoS requirements. A power control mechanism with multiple loops is used to adjust the transmit power of each terminal. The overlapping factor and QoS power control parameter are updated by two of the loops.

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 γ, 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： For soft handoff on the reverse link with restrictive reuse, a wireless terminal searches for pilots transmitted by sectors in a wireless system, measures the detected pilots, selects a serving sector (e.g., the strongest received sector), and identifies non-serving sectors that may receive high interference from the terminal. The serving sector assigns the terminal with subband(s) that are usable by the serving sector and unusable by the non-serving sectors. The terminal transmits data symbols on the assigned subbands to the serving and non-serving sectors. These sectors process the reverse link transmission from the terminal and obtain soft-decision symbols, which are estimates of the transmitted data symbols. The soft-decision symbols from co-located sectors may be combined and then decoded to obtain decoded packets. The sectors may also independently decode the soft-decision symbols, and the decoded packets from these sectors may be combined to obtain final decoded packets for the terminal.

摘要： Methods, systems, and devices for wireless communications are described. In some wireless communications system, a base station may schedule multiple user equipment (UEs) for unicast transmissions using a single downlink control information (DCI) format. For example, a first UE may receive, from a base station, DCI that includes unicast scheduling information for multiple UEs including the first UE. The first UE may determine, from the unicast scheduling information, a set of resources on which to communicate data with the base station. In such cases, the UE may transmit or receive data transmissions using the determined set of resources. In some examples, each UE of the multiple UEs may determine respective sets of resources based on one or more UE-specific transformation rules applied to common scheduling parameters of the DCI.

摘要： Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support interference mitigation for remote devices. A first wireless device (e. g., a base station) may detect remote interference with its communications caused by a second wireless device (e. g., a second, remote base station) based on, for example, a measured interference over thermal noise level exceeding a threshold. The first wireless device may identify a set of time-frequency resources for remote interference reference signals and a data transmission for a user equipment (UE) that is in communication with the first wireless device. The first wireless device may transmit a remote interference signal to a second wireless device (e. g., a second base station) via the set of time-frequency resources. The first wireless device may further signal a resource allocation to the UE for the UE to use for transmitting uplink transmissions to the first wireless device.

摘要： Certain aspects of the present disclosure provide techniques for performing interference mitigation. An exemplary method generally includes determining a first configuration for a first victim-aggressor pair including a first victim base station (BS) and a first aggressor base station (BS) to use to mitigate interference, wherein the first configuration indicates time and frequency resources for transmission of victim reference signals (RSs) by the first victim BS to indicate the presence of interference and for transmission of aggressor reference signals (RSs) by the first aggressor BS to indicate detection of victim RSs, wherein the first configuration is based at least in part on feedback from the first victim-aggressor pair and transmitting the first configuration to the first victim-aggressor pair.

摘要： A method for wireless communications may selectively allocate sequences for Non-Orthogonal Multiple Access (NOMA). In the method, a user equipment may send a transmission request to a base station for assignment of uplink sequences. The user equipment may receive an assignment of a first sequence and a second sequence from the base station. The first sequence has a first cross-correlation value with the second sequence and a second cross-correlation value with a third sequence assigned to a second user equipment, and the second sequence has a third cross-correlation value with the third sequence. The first cross-correlation value may be greater than the second cross-correlation value, and the first cross-correlation value may be greater than the third cross-correlation value. The user equipment may send uplink data to the base station using the first sequence and using the second sequence.
