[0057] The following discussion Figures 1 to 5 The various embodiments used to describe the principles of the present disclosure in this patent document are for illustration only and should not be interpreted in any way as limiting the scope of the present disclosure. Those skilled in the art will appreciate that the principles of the present disclosure can be implemented in any appropriately arranged system or device.

[0058] Figure 1 It is an exemplary system architecture 200 according to various embodiments of the present disclosure. Other embodiments of the system architecture 200 can be used without departing from the scope of the present disclosure. User equipment (UE) 201 is a terminal device used to receive data. The next generation radio access network (NG-RAN) 202 is a radio access network, which includes a base station (gNB or eNB connected to the 5G core network 5GC, and the eNB connected to the 5GC is also called ng-gNB) that provides a wireless network interface for the UE to access. The access control and mobility management function entity (AMF) 203 is responsible for managing the mobility context and security information of the UE. The user plane function entity (UPF) 204 mainly provides user plane functions. The session management function entity SMF205 is responsible for session management. The data network (DN) 206 includes services such as operators, access to the Internet, and third-party services.

[0059] In the NR system, in order to support network function virtualization, more efficient resource management and scheduling, the base station (gNB / ng-eNB) that provides a wireless network interface for the terminal (UE) can be further divided into a centralized unit gNB-CU / ng-eNB-CU (gNBcentral unit / ng-eNB central unit) and a distributed unit gNB-DU / ng-eNB-DU (gNB distributedunit / ng-eNB distributed unit) (referred to as CU and DU in this disclosure), such as Figure 2 As shown in (a), gNB-CU has radio resource control (RRC), service data adaptation protocol (SDAP: Service Data Adaptation Protocol) and packet data convergence protocol (PDCP) protocol layers, and ng-eNB-CU has RRC and PDCP layers.

[0060] gNB-DU / ng-eNB-DU has radio link control protocol (RLC), medium access control (MAC) and physical layer, etc. There is a standardized public interface F1 between gNB-CU and gNB-DU, and a standardized public interface W1 between ng-eNB-CU and ng-eNB-DU. The F1 interface is divided into control plane F1-C and user plane F1-U. The transmission network layer of F1-C is based on IP transmission. In order to transmit signaling more reliably, the SCTP protocol is added on top of IP. The application layer protocol is F1AP (F1 interface application protocol), see 3GPP TS38.473. SCTP can provide reliable application layer message transmission. The transport layer of F1-U is UDP / IP, and GTP-U is used to carry user plane protocol data unit PDU on top of UDP / IP. Furthermore, for gNB-CU, such as Figure 2 As shown in (b), the gNB-CU may include gNB-CU-CP (control plane part of the centralized unit of the base station) and gNB-CU-UP (user plane part of the centralized unit of the base station). The gNB-CU-CP includes the control plane function of the base station, with RRC and PDCP protocol layers, and the gNB-CU-UP includes the user plane function of the base station, with SDAP and PDCP protocol layers. The standardized public interface E1 is used between the gNB-CU-CP and the gNB-CU-UP, and the protocol is E1AP, see 3GPP TS38.463. The interface between the control plane part of the centralized unit of the base station and the distributed unit of the base station is the F1-C interface, i.e., the control plane interface of F1, and the interface between the user plane part of the centralized unit of the base station and the distributed unit of the base station is the F1-U interface, i.e., the user plane interface of F1. In addition, in the NR system, the base station that provides the E-UTRA user plane and control plane accessing the 5G core network is called ng-eNB. In order to support virtualization, this base station (ng-eNB) can also be further divided into a centralized unit ng-eNB-CU (gNB central unit / ng-eNB central unit) and a distributed unit ng-eNB-DU (gNB distributed unit / ng-eNB distributed unit) (referred to as CU and DU in this disclosure), such as Figure 2As shown in (c). ng-eNB-CU has RRC and PDCP layers. gNB-DU / ng-eNB-DU has radio link control protocol (RLC), medium access control (MAC) and physical layer, etc. There is a standardized public interface W1 between ng-eNB-CU and ng-eNB-DU. The W1 interface is divided into control plane W1-C and user plane W1-U. The transport network layer of W1-C is based on IP transmission. In order to transmit signaling more reliably, the SCTP protocol is added on top of IP. The protocol of the application layer is W1AP, see 3GPP TS37.473. The transport layer of W1-U is UDP / IP, and GTP-U is used to carry user plane protocol data unit PDU on top of UDP / IP.

[0061] At present, regarding the quality of experience (QoE), the configuration and reporting of the quality of experience (QoE) measurement of the air interface (radio interface, or Uu interface, i.e., the interface between the terminal and the access network) are mainly studied, and the measurement configuration and / or reporting of the sidelink are not studied. The present disclosure mainly relates to the measurement configuration and / or reporting of the sidelink. In various embodiments of the present disclosure, various methods and devices for configuring and / or reporting QoE measurements related to the sidelink are provided.
