In one example, a method includes generating a near-optimal power pattern for PC and scheduling in accordance with long term channel statistics. The near-optimal PC solution may be generated by first generating a set of possible power patterns in accordance with likely scheduling scenarios, then statistically narrowing the set of possible power patterns to identify the most commonly used power patterns, and finally selecting one of the most commonly used power patterns as the near-optimal power pattern. In another example, a table of optimal PC solutions are provided for performing distributed PC and scheduling in an adaptive and/or dynamic manner.

Abstract: Backhaul resource utilization efficiency can be improved by performing lower-layer decoding of uplink transmissions at access points to obtain transport blocks carried by the uplink transmissions, and then strategically scheduling the transport blocks over backhaul links extending between the access points and network nodes. Upon reception, the network nodes may perform radio link control (RLC) decoding of the transport blocks to obtain the uplink data. Transport blocks may be scheduled a manner that prioritizes time-sensitive data (e.g., voice traffic), or in a manner that strategically routes transport blocks over backhaul paths to increase the overall utilization of backhaul resources.

Abstract: Increased resource utilization efficiency can be improved by modeling path costs during admission and path-selection. Specifically, path costs for candidate paths are modeled based on load characteristics (e.g., current load, load variation, etc.) of links in the candidate paths. Path costs can represent any quantifiable cost or liability associated with transporting a service flow over the corresponding path. For example, path costs can correspond to a probability that at least one link in the path will experience an outage when transporting the service flow, a price charged by a network operator (NTO) for transporting the traffic flow over the candidate path, or a total network cost for transporting the flow over a candidate path. The candidate path having the lowest path cost is selected to transport a service flow.

Abstract: Interference costs on virtual radio interfaces can be modeled as a function of loading in a wireless network to estimate changes in spectral efficiency and/or resource availability that would result from a provisioning decision. In one example, this modeling is achieved through cost functions that are developed from historical and/or simulated resource cost data corresponding to the wireless network. The cost data may include interference data, spectral efficiency data, and/or loading data for various links over a common period of time (e.g., a month, a year, etc.), and may be analyzed and/or consolidated to obtain correlations between interference costs and loading on the various links in the network. As an example, a cost function may specify an interference cost on one virtual link as a function of loading on one or more neighboring virtual links.

Abstract: A controller having access to channel information associated with a neighboring access point (AP) may communicate a mask to a served user equipment (UE). The mask may specify transmission parameters for an uplink transmission between the served UE and a serving AP such that a successful decoding probability of the uplink transmission at the neighboring AP exceeds a threshold. The mask may specify a maximum MCS level for the uplink transmission, a minimum transmit power level for the uplink transmission, and/or a precoder constraint for the uplink transmission that produces constructive interference at a spatial location of the neighboring AP. This may enable the neighboring AP to isolate the uplink transmission from uplink wireless signals using an interference cancellation technique, e.g., successive interference cancellation (SIC) techniques.

Abstract translation: 具有访问与相邻接入点（AP）相关联的信道信息的控制器可以向服务用户设备（UE）传送掩码。 该掩码可以指定所服务的UE与服务AP之间的上行链路传输的传输参数，使得相邻AP上的上行链路传输的成功解码概率超过阈值。 掩模可以指定用于上行链路传输的最大MCS级别，用于上行链路传输的最小发射功率级别和/或用于在相邻AP的空间位置处产生建设性干扰的上行链路传输的预编码器约束。 这可以使相邻AP使用干扰消除技术（例如连续干扰消除（SIC））技术来将上行链路传输与上行链路无线信号隔离开。
