摘要： A method and system for identifying cell clusters within a coordinated multiple point wireless transmission network in order to reduce scheduling complexity while optimizing throughout and performance. The network includes a total number of cells served by corresponding base stations. The BSC divides the entire network of cells into clusters of cells and forwards this clustering information to all mobile devices. A cluster of cell candidates is a subset of the total number of cells within the network. The mobile device then provides to a base station controller the identity of a cluster of preferred cells selected from the cluster of cell candidates. The base station controller selects at least one base station located within the cluster of preferred cells to establish communication with the mobile device. A wireless connection is then established between the selected at least one base station and the mobile device.

摘要： Carrier aggregation and dual connectivity leverage multiple component carriers to increase the effective bandwidth available to a given UE. Embodiments of this disclosure extend the concept of carrier aggregation and dual connectivity by using a physical component carrier and one or more virtual component carriers from one physical component carrier group and/or one virtual component carrier group, which have the same carrier frequency and carrier bandwidth as the physical component carrier, to transmit data streams to a user equipment. Data streams communicated over the physical component carrier and the virtual component carrier (s) may be orthogonal in the time domain or code domain. Alternatively, data streams communicated over the physical component carrier and the virtual component carrier (s) may be non-orthogonal, in which case the UE may need to decode the respective data streams using non-orthogonal signal processing techniques.

摘要： The computational complexity of MCS adaptation for linear and non-linear MU-MIMO can be reduced by avoiding QR decomposition during subsequent stages of MCS adaptation. For instance, QR decomposition can be avoided in later stages of MCS adaptation by computing an instant upper right triangular matrix (R 1 ) directly from an earlier upper right triangular matrix (R) and an earlier unitary matrix (U), which were obtained during a previous stage of MCS adaptation. As such, the instant upper right triangular matrix (R 1 ) is obtained without performing QR decomposition on an instant Hermitian matrix ( H 1 H ), thereby allowing MCS adaptation to be performed for the new user group with less complexity. Additionally, computational complexity of MCS adaptation for linear MU-MIMO can be further reduced by avoiding matrix inversion during subsequent stages of MCS adaptation.
摘要翻译：通过在MCS适应的后续阶段避免QR分解，可以减少线性和非线性MU-MIMO的MCS适应的计算复杂度。例如，可以通过直接从较早的右上角三角矩阵（R）和较早的单位矩阵（U）计算即时右上角三角矩阵（R）和较早的单位矩阵（U）来在MCS适应的后期阶段避免QR分解，这是在 MCS适应的前期阶段。这样，即时的右上角三角矩阵（R1）在瞬时赫敏矩阵（H 1 H）下不执行QR分解，从而允许以较不复杂的方式为新的用户组执行MCS适配。此外，通过在MCS适应的后续阶段避免矩阵反演，可以进一步减少用于线性MU-MIMO的MCS适应的计算复杂度。

摘要： A computing system and a method is provided for determining a network traffic routing path from a source node to a destination node through a service function chain (SFC). A joint network slicing and traffic engineering problem is provided that may be solved to identify network slicing configuration and traffic engineering parameters to provide a set of function nodes, the SFC, and the network traffic routing path from the source node to the destination node. The joint network slicing and traffic engineering problem P may be solved by minimizing a resource objective associated with the joint network slicing and traffic engineering problem, in accordance with a set of one or more constraints. Instructions may be transmitted to a network orchestrator to create the service function chain in a network slice on the set of network nodes in accordance with the identified network slicing configuration and traffic engineering parameters, to provide the network traffic routing path.
