Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a resource allocation method, a channel measurement method, a device, and an apparatus.
Background
The 5G network provides differentiated service quality through end-to-end slices, such as eMBB (Enhanced Mobile Broadband) slices providing large bandwidth services, URLLC (Ultra-reliable and Low Latency Communications) slices providing Low Latency services, and so on. 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 a logical channel, thereby implementing high priority scheduling of a service of a specific slice.
However, after the services of different slices are differently scheduled, the same processing method is still used for the transmission of each service during the physical layer transmission.
Although prior art can implement the priority scheduling of the service of a specific slice by mapping the slices layer by layer, the physical layer transmission method after scheduling cannot perform differentiation processing according to the service type to which the slice belongs, for example, a high-robustness physical layer transmission is required on a part of high-reliability service scheduling RB (resource block), a low-order MCS (Modulation and Coding Scheme) and a physical layer transmission Scheme with a low flow number are required on the physical layer; the RB scheduled by the large bandwidth service requires the physical layer to perform a physical layer transmission scheme with a high-order MCS and a high stream number. 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 requirement, so that differentiated channel quality assessment cannot be performed according to the service requirement assessment.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a resource configuration method, applied to a network device, where the method includes:
In this embodiment, by informing the service type (which may also be a slice type) to which the current data packet belongs to the physical layer, the network device and the terminal 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 affecting the subsequent transmission strategy for the service data packet.
In an optional embodiment of the present invention, the service type information includes: slice identification of a network slice and/or quality of service information of a traffic of a QoS flow of the network slice. The identification of the network slice may indicate a type of the network slice, and the traffic quality of service information of the QoS flow of the network slice may also indicate a type of the network slice.
In an optional embodiment of the present invention, in step 12, mapping the service type information to a physical layer includes:
step 121, mapping the service type to a data transmission resource of a physical layer. Specifically, the higher layer of the base station maps the service type to the data transmission bearer of the physical layer. Therefore, the physical layer can adopt the MCS level and/or the number of the data streams which are adaptive to the service type to transmit data on the data transmission bearer. Specifically, the MCS level and/or the number of data streams may be scheduled by the MAC layer.
In the above embodiments of the present invention, the CSI-RS sending resource configuration information includes at least one of:
time domain resources of CSI-RS sending resources of a serving cell and a neighboring cell;
frequency domain resources of a serving cell and a neighboring cell;
the airspace resources and the port number of the service cell and the adjacent cell.
Optionally, the time domain resource includes a period, a frame, and a symbol for transmitting CSI-RS;
the frequency domain resource comprises a bandwidth and a resource block for transmitting CSI-RS;
the spatial domain resources include a beam direction for transmitting the CSI-RS, a beam horizontal/vertical width, a beam gain, and an update frequency of the beam direction.
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 performing channel measurement according to the CSI-RS sending resource configuration information;
in the step, after receiving the resource configuration information sent by the CSI-RS, the terminal measures CQI and/or RI and the like on the information indicated by the resource sent by the CSI-RS, reports the measurement result to the base station and can report the measurement result through RRC signaling;
and step 15, performing data transmission on the data transmission resource corresponding to the service type according to the channel measurement result.
The physical layer may transmit data on the data transmission bearer using the MCS level and/or the number of data streams adapted to the service type. Specifically, the MCS level and/or the number of data streams may be scheduled by the MAC layer.
For the sake of convenience of description, a service concurrency of 2 different slices for one user is taken as an example to illustrate the specific implementation method of the above embodiment, where the network slice 1 is a large bandwidth data service, and the network slice 2 is a high reliability service. The scheduling priority of network slice 2 is higher than slice 1.
One implementation of the foregoing embodiment includes:
step 1: a gNodeB RRC (radio resource control) layer receives and identifies slice identifiers of two network slices and service quality information of QoS (quality of service) flows of each slice, maps the service QoS flows to a DRB (data radio bearer) and a logic channel, and realizes that the scheduling priority of a network slice 2 is higher than that of a network slice 1 through an MAC (media access control) layer of a base station;
step 2: the base station maintains configuration information of 2 sets of CSI-RS (channel state information-reference signal) transmission resources, wherein the first set of configuration information is suitable for channel measurement of large-bandwidth services, and adopts configurations such as low-density transmission period, transmission beams with narrow horizontal and vertical beam widths, transmission direction refreshing according to SRS measurement and the like; the second set of configuration information is suitable for channel measurement of high-reliability services, and is configured by adopting a high-density transmission period, a transmission beam with a wider horizontal and vertical beam width, a fixed limited number of transmission directions and the like.
And step 3: and the base station issues the two sets of configuration information to the terminal, configures two sets of CSI-RS resources and simultaneously configures the associated service type information for each set of CSI-RS resources. 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 a plurality of sets of CSI-RS resources for the terminal, the service type identifier is adopted to identify the service type information adapted to the CSI-RS resources.
The specific message content of the service type message is as follows:
wherein, the servicetypeidentifier and servicetypeidentifier ID may include, but is not limited to, a slice ID or a 5QI identifier describing service quality of a service;
and 4, step 4: and the terminal maps the service type information in the CSI-RS configuration into a corresponding service requirement, and correspondingly feeds back and reports measurement results such as CQI (channel quality information), RI (rank) and the like. The measurement result of CQI may include, but is not limited to, mapping the service requirement to indexes such as spectrum efficiency, isbler, and time delay, and selecting a matched CQI-Table (measurement result of CQI) for feedback; the measurement result of RI may include, but is not limited to, mapping the service requirement to the indexes of spectral efficiency, isbler, time delay, etc., and selecting the matched RI for feedback.
And 5: and the network side performs data transmission on the RB (resource block) scheduled by the network slice 1 according to the CQI _1 and the RI _1 reported by the terminal to the network slice 1, and performs data transmission on the CQI _2 and the RI _1 reported by the network slice 2 and the RB scheduled by the network slice 2. 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 embodiment of the present invention, 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 is notified, so that the physical layer can use the CSI-RS transmission resource adapted to the service requirement and the feedback result to perform the measurement of the channel quality, thereby realizing the transmission of the differentiated physical layer service data packet matching the service requirement.
As shown in fig. 2, an embodiment of the present invention further provides a channel measurement method, applied to a terminal, where the method includes:
and step 23, reporting the channel measurement result to the network equipment.
In the embodiment, the terminal receives the CSI-RS transmission resource adapted to the service requirement, performs channel quality measurement, and reports the measurement result to the base station, so that the physical layer of the base station can call the corresponding MCS level and/or the corresponding number of data streams according to the service type, and perform transmission of the corresponding service data packet.

and performing channel measurement according to the service requirement to obtain a channel measurement result.
