Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for configuring resources, a method for measuring a channel, a device and equipment.
Background
The 5G network provides differentiated quality of service through end-to-end slices, such as eMBB (Enhanced Mobile Broadband ) slices provide large bandwidth services, while URLLC (Ultra-reliable and Low Latency Communications, high reliability and low latency communications) slices provide low latency services, etc. The 5G base station maps QoS Flow (quality of service QoS Flow) under PDU Session (protocol data unit Session) corresponding to a slice to DRB (data radio bearer) and logical channel, thereby realizing high priority scheduling of traffic of a specific slice.
However, after different scheduling is implemented for the services of different slices, the same processing method is still adopted for the transmission of each service during the transmission of the physical layer.
Although the prior art can implement preferential scheduling of services of a specific slice through layer-by-layer mapping of the slice, the physical layer transmission method after scheduling cannot perform differentiated processing according to the service type to which the slice belongs, for example, physical layer transmission with high robustness is required on part of RBs (resource blocks) of high-reliability service scheduling, a physical layer is required to perform a low-order MCS (Modulation and Coding Scheme, modulation and coding strategy) and a physical layer transmission scheme with lower flow number, and a physical layer is required to perform a physical layer transmission scheme with high-order MCS and higher flow number on RBs of high-bandwidth service scheduling. However, in the prior art, the physical layer does not distinguish the processes of channel measurement and the like on all RBs according to the service requirements, so that differentiated channel quality evaluation cannot be performed according to the service requirement evaluation.

The identification of the network slice may represent the type of network slice, and the quality of service information of the QoS flow of the network slice may also represent the type of network slice.
In an optional embodiment of the present invention, in step 12, mapping the service type information to a physical layer includes:
And step 121, mapping the service type to the data transmission resource of the physical layer. Specifically, the higher layer of the base station maps the service type to the data transmission bearer of the physical layer. So that the physical layer can transmit data on the data transmission bearer by adopting the MCS level and/or the number of data streams which are adapted to the service type. In particular, the MCS level and/or the number of data streams may be scheduled by the MAC layer.
In the above embodiment of the present invention, the CSI-RS transmission resource allocation information includes at least one of the following:

In an optional embodiment of the present invention, the method for configuring resources may further include:
Step 14, receiving a channel measurement result sent by a terminal, wherein the channel measurement result is obtained by carrying out channel measurement according to the CSI-RS sending resource allocation information;
in the step, after receiving the configuration information of the CSI-RS transmission resource, the terminal measures CQI and/or RI and the like in the information indicated by the CSI-RS transmission resource, and reports the measurement result to the base station, and the measurement result can be reported through RRC signaling;

The physical layer may transmit data on the data transmission bearer using an MCS level and/or the number of data streams adapted to the service type. In particular, the MCS level and/or the number of data streams may be scheduled by the MAC layer.
For simplicity of description, the specific implementation method of the above embodiment is described by taking the concurrency of services in which one user has 2 different slices as an example, where the network slice 1 is a large bandwidth data service, and the network slice 2 is a high reliability service.

Wherein the traffic type message may include, but is not limited to, an identification of a network slice or a 5QI identification describing the quality of service of the traffic. One implementation method of step 3 is that when the base station configures multiple sets of CSI-RS resources for the terminal, a service type identifier is used to identify a service type message adapted to the CSI-RS resources.
The specific message content of the service type message is as follows:
Wherein servicetypeindicator and servicetypeindicatorID, which may include, but are not limited to, slice ID or 5QI identification describing the quality of service of the traffic;

Although the channel from the base station to the user is unchanged for a short time, cqi_1 is generally different from cqi_2, ri_1 and ri_2 depending on the channel quality measurement methods corresponding to slice 1 and slice 2.
In the above embodiment of the present invention, by informing the physical layer of the service type message (such as the slice ID, the 5QI service requirement corresponding to the service type, etc.) to which the current scheduling data packet belongs, the physical layer can use the CSI-RS transmission resource and the feedback result adapted to the service requirement to perform the measurement of the channel quality, thereby implementing the transmission of the differentiated physical layer service data packet matching the service requirement.
