Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

Fig. 1 is one of the flow diagrams of the layer 2 measurement method provided by the embodiment of the present disclosure. As shown in Fig. 1, the embodiment of the present disclosure provides a layer 2 measurement method, and the execution subject may be a terminal (relay terminal or remote terminal) terminal), such as a mobile phone, etc. In this method, a direct communication link has been established between the remote terminal and the relay terminal, including:

Step 101: Determine the measurement information associated with the layer 2 measurement by performing layer 2 measurement on the first terminal that uses the direct communication link for data transmission, the measurement information associated with the layer 2 measurement includes an average throughput One or more of measurement information of data packet delay, measurement information of data packet delay, and measurement information of data packet loss rate, wherein the first terminal is a remote terminal or a relay terminal.

Specifically, FIG. 2 is a schematic diagram of a scenario in which a relay terminal serves a remote terminal. As shown in FIG. 2 , the remote UE communicates with the relay UE using a direct communication interface. The direct communication interface may be a PC5 interface. The link between the remote UE and the relay UE is a direct communication link (Sidelink). The Uu interface is used for communication between the relay UE and the network device, and the link between the relay UE and the network device is a backhaul link (BH). A remote UE is connected to the network through a relay UE.

Figure 3 is a schematic diagram of a scene where multiple relay terminals serve a remote terminal. As shown in Figure 3, the remote UE and the relay UE 1 use the PC5 interface for communication, and the communication between the remote UE and the relay UE The link is Sidelink, the relay UE 1 and the relay UE N use the PC5 interface for communication, the link between the relay UE1 and the relay UE N is also Sidelink, and the relay UE N and the network equipment use Uu The interface communicates, and the link between the relay UE N and the network device is a Backhaul link. A remote UE is connected to the network through multiple relay UEs.

For example, the remote terminal performs layer 2 measurement on itself, and acquires measurement information associated with the layer 2 measurement.

Or for example, the relay terminal performs layer 2 measurement on itself, and acquires measurement information associated with the layer 2 measurement. What needs to be explained here is that, according to the starting point (or end point) of the transmitted data, the relay terminal can divide the transmitted data into the data to be transmitted by itself and the data to be forwarded by the remote terminal. According to the aforementioned data classification, the layer 2 measurement here can be divided into: performing layer 2 measurement for the data to be transmitted by itself and performing layer 2 measurement for the data forwarded by the remote terminal.

The measurement information associated with the layer 2 measurement may include one or more of measurement information of average throughput, measurement information of packet delay, and measurement information of packet loss rate.

Specifically, the average throughput measurement is aimed at the measurement of a single relay terminal or remote terminal, which is convenient for network equipment to observe the throughput of each relay terminal or remote terminal, and assists the network in performing remote terminal and relay terminal configuration optimization.

The average throughput measurement is divided into uplink (UpLink, UL) and downlink (Downlink, DL). The UL or DL average throughput measurement of the remote terminal can be carried by each direct communication link data radio bearer of each remote terminal (per remote User Equipment per Sidelink Data Radio Bearer, per remote UE per SL-DRB) Or each remote terminal (per remote User Equipment, per remote UE) or each data radio bearer of each remote terminal (per remote User Equipment per Data Radio Bearer, per remote UE per DRB) is measured as a unit.

Uplink data transmission is a process in which the remote terminal sends data to the relay terminal, and the relay terminal forwards the data to the network device.

In the case of uplink data transmission and the relay terminal measures the average throughput, the average throughput can be understood as the UL average throughput value calculated by the relay terminal based on the transmitted uplink data; the measurement associated with the average throughput The information can be understood as the associated measurement information obtained by performing UL throughput measurement by the relay terminal to calculate the UL average throughput value; the average throughput can also be understood as the UL data transmitted by the relay terminal as determined by the remote terminal, Calculate the UL average throughput value when transmitting UL data for the remote terminal; the measurement information associated with the average throughput can be understood as the UL average throughput value calculated by the relay terminal when transmitting UL data for the remote terminal Perform UL throughput measurement to obtain associated measurement information; the identification information of the remote terminal refers to the identification information of the remote terminal whose average throughput is measured by the relay terminal, that is, adding a physical cell ID (PCI ), or Cell Global ID (CGI) or L2 ID.

If the transmitted data is downlink data, the way to understand the average throughput and the measurement information associated with the average throughput is similar to that described above, the difference is: whether the data is uplink data or downlink data, which will not be repeated here.

If the relay terminal provides services for multiple remote terminals, the relay terminal can simultaneously obtain one or more of the average throughput, measurement information and identification information associated with the average throughput of the multiple remote terminals. The relay terminal can simultaneously report the average throughput-related measurement information of multiple remote terminals.

Specifically, the total time delay of the uplink data packet may be the time delay when the data packet is sent from the remote terminal to the network side device. The total delay of the downlink data packet may be the delay of sending the data packet from the network side device to the remote terminal.

The uplink data packet delay can be the delay when the data packet is sent from the relay terminal or the remote terminal to the next-hop relay terminal, and the downlink data packet delay can be the time delay when the data packet is sent from the relay terminal to the next-hop relay terminal or the next-hop relay terminal. One-hop delay of the remote terminal.

In order to calculate the data packet delay of the remote terminal, the delay of each segment may be calculated firstly, and then the segmental delays are summed to obtain the uplink or downlink data packet delay of the remote terminal.
