Systems and methods for resource-specific reference signal configuration

#The present disclosure relates generally to wireless communications, and in particular embodiments, to systems and methods for resource-specific reference signal configuration.

#In some wireless communication systems, user equipments (UEs) wirelessly communicate with one or more transmit/receive points (TRPs) to send data to the TRPs and/or receive data from the TRPs. A wireless communication from a UE to a TRP is referred to as an uplink communication. A wireless communication from a TRP to a UE is referred to as a downlink communication.

#A UE may be served by a serving cell that includes one or more TRPs. The UE may communicate with the one or more TRPs to send uplink communications and receive downlink communications.

#For a more complete understanding of the present embodiments, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:

#FIG. 1 illustrates an example of a telecommunications network according to one embodiment;

#FIG. 2 illustrates the presence of three TRPs cooperating to serve a cell, according to one embodiment;

#Signaling designs relate to the design of uplink or downlink transmissions that convey information about the network. Signaling designs include the design of transmissions that inform a UE of reference signal resource configurations, and the design of transmissions that inform the network of measurement results. According to some signaling designs, CSI-RS resource configurations are signaled to a UE in a cell-specific manner. These signaling designs identify a set of cells by their respective physical identities, and then identify the CSI-RS resource configurations for each cell. Measurement reporting is also performed in a cell-specific manner. Each measurement result in a measurement report is associated with a cell identity. An issue with these signaling designs is that they explicitly tie a set of reference signal resources to a given cell, and provide the UEs with knowledge of the cells within the network. In the event of a handover from one serving cell to another, a UE may need to be reconfigured with new CSI-RS resource configurations. In addition, some parameters of the CSI-RS resource configurations may be fixed for each cell.

#Different embodiments are presented herein that may facilitate increasing the flexibility and/or efficiency of signaling designs for CSI-RS resource configurations and measurement reports. In some embodiments, configured CSI-RS resources are signaled to a UE in a cell-transparent manner. Although the CSI-RSs may be associated with specific cells, the signaling design does not provide a UE with knowledge of the cells the CSI-RSs are associated with. Instead, the UE identifies the CSI-RSs by their respective resources. The CSI-RS resources may be configured independent from cell identifiers. An identifier of a cell may be any parameter that may be used to determine the identity of a cell. An identifier of a cell may include, for example, a cell identity. A cell identity may also be referred to as a physical cell identity. An identifier of a cell may also be stored in a CSI-RS index. The UE monitors the configured CSI-RS resources and generates measurement results for the successfully received CSI-RSs. These measurement results are reported by the UE in the form of a measurement report, e.g. to a serving cell, based on the CSI-RS resources that were used to generate them. Each measurement result in the measurement report is identified by its configured CSI-RS resources. The measurement reports do not necessarily contain the identifier of the cell. Moreover, the measurement reports do not necessarily contain any indication of a cell identity. Further embodiments relate to a UE reporting acknowledgements for the successful detection of SSBs associated with the CSI-RSs in the measurement report.
