摘要： In a method for resolving PCT conflicts in a new radio (NR) network, synchronization signal and PBCH (Physical Broadcast Channel) blocks (SSB) and corresponding physical cell identifiers (PCIs) are utilized. In the method, a first PCI corresponds to a first SSB and a second PCI corresponds to a second SSB. An access network device determines, based on the first PCI and the second PCT, that the first PCI conflicts with the second PCI. In this way, PCI conflicts in an NR system can be detected to improve the success rate and to reduce the call drop rate in a terminal handover.

摘要： Aspects described herein relate to a network for providing air-to-ground wireless communication in various cells. The network includes a first base station array, each base station of which includes a respective first antenna array defining a directional radiation pattern that is oriented in a first direction, wherein each base station of the first base station array is disposed spaced apart from another base station of the first base station array along the first direction by a first distance. The network also includes a similar second base station array where the second base station array extends substantially parallel to the first base station array and is spaced apart from the first base station array by a second distance to form continuous and at least partially overlapping cell coverage areas between respective base stations of the first and second base station arrays.

摘要： Systems and methods for determining an assignment of radio resources to antennas are provided. In some embodiments, a method includes obtaining an antenna deployment including antennas and corresponding locations for the antennas; determining a cell assignment for the antennas such that each antenna is assigned to one cell out of one or more cells; and, based on the cell assignment, determining a resource assignment for the antennas such that each antenna is assigned to one radio resource out of one or more radio resources. In this way, some embodiments disclosed herein provide a lightweight and efficient method to design a distributed antenna deployment. In some embodiments, the resulting network is optimized in terms of the total area where a high rank is achieved.

摘要： A process receives performance parameter measurements associated with multiple cell sectors of a group of multiple Remote Radio Units (RRUs) and determines a first set of cell sectors of the multiple cell sectors to include in a first cell sector cluster based on the measured performance parameters. The process configures connections, between the first set of cell sectors included in the first cell sector cluster and a first Baseband Unit (BBU) of multiple BBUs of a Centralized Radio Access Network (CRAN) hub, such that the first BBU processes traffic to and from the first set of cell sectors included in the first cell sector cluster.

摘要： A set of different pilot structures are designed for use in different environments and/or different user behaviours that are expected to occur in a cell. The radio conditions for a user are estimated. Each user is then assigned an area (108A-E) in resource space for its communication, which has a suitable pilot configuration. In one embodiment, the entire resource space is provided with different pilot structures in different parts (110A-D) In advance and allocation of resources to the users are then performed in order to match estimated radio conditions to the provided pilot structure. In another embodiment, allocation is performed first, and then the actual pilot structure is adapted within the allocated resource space area to suit the environmental conditions.

摘要： A system for allocating resources in a communications network includes a plurality of access points, where each access point in the plurality of access points is in communication with one or more user devices. The system also includes a central controller in communication with the plurality of access points. The central controller is configured to receive traffic information and channel information for access point—user device links in the communications network. The central controller is also configured to receive an intensity of independent homogeneous Poisson traffic intended for the one or more user devices. The central controller is further configured to determine a joint resource allocation based at least in part on the received traffic and channel information and the intensity of independent homogeneous Poisson traffic, where the joint resource allocation is determined with an algorithm.

摘要： Provided are a method for a UE to transmit and receive data in a wireless communication system and an apparatus therefor. The UE receives downlink control information from a base station. The downlink control information includes an indicator for configuring the bundling size of a downlink shared channel. The UE receives downlink data from the base station through a downlink shared channel configured based on the downlink control information. The bundling size may be configured based on a value of the indicator.

摘要： A forwarding entry generation method includes sending, by a controller, a plurality of resource allocation request messages to a plurality of network devices in a network slice, to trigger the plurality of network devices to allocate resources, where the resource allocation request message includes an identifier of the network slice and a resource that needs to be allocated by a corresponding network device to the network slice; receiving, by the controller, a plurality of resource allocation response messages including the identifier of the network slice and a segment identifier of a corresponding network device, and a resource allocated by each device belongs to the network slice; and generating, by the controller, a forwarding table corresponding to the network slice, where the forwarding table includes a forwarding entry for arriving at a network device in the network slice.
