摘要： Systems and methods for the generation of sensing signals and sensing signal configurations for a wireless communication network are provided. In an embodiment, a sensing node identifier (ID) associated with a network entity is determined. This sensing node ID is used to determine a sensing signal configuration, which includes a resource configuration and a symbol sequence. The resource configuration is selected from a set of physical resources associated with a wireless communication network. The symbol sequence is based on the sensing node ID and is specific to the network entity in the wireless communication network. A sensing signal can be transmitted according to the sensing signal configuration.

摘要： Aspects of the present disclosure provide signalling that enables adaptively selecting a transmission scheme for different scenarios. Examples of the transmission schemes that may be selected from include beamforming, a channel modulation transmission scheme, (such as media-based modulation (MBM) or spatial modulation (SM)) or a hybrid of those two transmission schemes. The methods provided herein may apply to uplink, downlink, sidelink or backhaul scenarios.

摘要： Systems and methods are provided for transmit signalling to configure a UE with a UE specific root to use in generating a Zhadoff Chu (ZC) sequence for reference signal transmission. With conventional LTE, a cell specific root is used within each cell. There is a need for a more flexible association between roots and UEs that, for example, allows for multiple roots to be associated with a cell. The provided approach may help with maintaining re-use distance as networks become denser. The method provided in this embodiment improves the capabilities of automatic driving and ADAS of electric vehicles. The method can be applied to vehicle networking, such as V2X, LTE-V, V2X, etc.

摘要： Methods and devices for configurable sequence usage for user equipment (UE) uplink reference signaling are provided. In one provided method, a transmission reception point (TRP) in a wireless communication network receives a first UL reference signal (RS) associated with a first UL RS sequence from a first UE and receives a second UL RS associated with a second UL RS sequence from a second UE, the first and second UL RS sequences being non-orthogonal. In another provided method, A UE determines an UL RS sequence based on a UL RS sequence root, the UL RS sequence root being a UE-specific root and being independent of a cell identifier of a cell serving the UE. The UE sends an UL RS associated with the UL RS sequence, the UL RS sequence being a Zadoff-Chu sequence.

摘要： Systems and methods are disclosed for partitioning resources into resource partitions, and informing user equipments (UEs) of the resource partitions. Knowledge of the resource partitions may assist the UEs in performing joint decoding. In one embodiment, a method performed by a UE includes receiving at least one message from each base station. The at least one message provides information indicating how resources are partitioned by the base station into a respective plurality of resource partitions. The information is used to identify respective resources for each of at least two downlink transmissions. Respective data that was transmitted on each of the at least two downlink transmissions using the respective resources is jointly decoded.

摘要： Various devices and methods are disclosed to support clustering optimization in a communication system. For example, multiple nodes of the communication system can be segmented into multiple clustering plans. Each clustering plan can include multiple clusters that do not overlap with one another within that clustering plan. At least one of the clusters of one clustering plan can overlap at least one of the clusters of at least one other clustering plan. Each node could be a non-boundary node in at least one cluster of at least one clustering plan. Multiple nodes of the communication system can alternatively be segmented into clusters having expanding and contracting borders.

摘要： A method of resource allocation for use in a wireless network is disclosed. A network coloring decision to assign a plurality of resource blocks to a plurality of cells within the wireless network is triggered upon occurrence of a network event. A network coloring is performed by assigning each cell of the plurality of cells a resource block from the plurality of resource blocks. An effect of interference among adjacent cells with a same resource block assignment is reduced as measured by a network performance metric related to a number of resource block assignment conflicts over the plurality of cells.
