Abstract: Systems and methods for dynamically selecting and adjusting energy detection thresholds (EDTs) in uncoordinated radio nodes deploying Listen Before Talk to improve throughput on shared spectrum are disclosed. The uncoordinated radio nodes dynamically adjust an EDT to avoid harmful collisions with neighboring radio nodes or otherwise improve throughput over shared spectrum. A radio node can detect a collision or radio frequency (RF) interference from a neighboring radio node. Once the collision or RF interference is detected, the EDT of the radio node is dynamically adjusted. In some cases, the collision or RF interference can be avoided by calculating a throughput of the radio node while operating on each of a plurality of EDTs and selecting the EDT predicted to result in a higher throughput. In other cases, the EDT may be dynamically adjusted based on an iterative approach which incorporates measurements of the neighboring radio node.

Abstract: A method for assessing an impact of a design choice on a system level performance metric of a radio access network (RAN) deployed in an environment includes receiving messages from a plurality of UEs over time by a plurality of RNs in the RAN. A design choice is selected for a set of operating parameters of the RAN. One or more of measurement values in each of the received messages and the selected design choice are processed to compute a set of derivatives. A system level performance metric is determined as a function of the computed set of derivatives.

Abstract: Systems and methods for dynamically selecting energy detection thresholds (EDTs) in radio nodes deploying listen before talk within a coordinated network to improve throughput on shared spectrum are disclosed. The radio nodes are configured to coordinate to deploy mechanisms to avoid or reduce interference issues, including collisions, with use of shared spectrum (e.g., unlicensed spectrum). One such mechanism is Listen Before Talk (LBT), and a radio node deploying LBT sets an EDT at which the radio node hears traffic from neighboring radio nodes on the shared spectrum. In an exemplary aspect, the EDT of radio nodes in the coordinated network of radio nodes can be dynamically selected and/or adjusted to improve throughput of the individual radio nodes and/or of the network of radio nodes as a whole.

Abstract: A method is shown for allocating a plurality of channels to a plurality of radio nodes (RNs) in a radio access network (RAN). In accordance with the method, an initial RN is selected from among the plurality of RNs. A first of the plurality of channels is assigned to the initial RN. The first channel is selected such that external interference experienced by the initial RN from sources other than the RAN on the first channel is minimized. A second RN is selected from among the plurality of RNs. A second of the plurality of channels is assigned to the second RN. The second channel is selected such that a metric reflective of an information carrying capacity of the RNs that have already been assigned one of the plurality of channels is maximized. The assigned channels are allocated to the respective RNs to which they have been assigned.
Abstract translation: 示出了用于将无线电接入网（RAN）中的多个无线电节点（RN）分配给多个信道的方法。 根据该方法，从多个RN中选择初始RN。 多个信道中的第一个被分配给初始RN。 选择第一信道，使得初始RN从第一信道上除RAN之外的源经历的外部干扰最小化。 从多个RN中选择第二RN。 多个信道中的第二个被分配给第二RN。 第二信道被选择为使得反映已经被分配多个信道中的一个的RN的信息承载容量的度量被最大化。 分配的信道被分配给它们被分配的相应的RN。
