Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a resource configuration method, a channel measurement method, a device and equipment. Background Art

[0002] 5G networks provide differentiated service quality through end-to-end slicing, such as eMBB (Enhanced Mobile Broadband) slicing for large bandwidth services, and URLLC (Ultra-reliable and Low Latency Communications) slicing for low latency services. 5G base stations map the QoS Flow (Quality of Service QoS Flow) under the PDU Session (Protocol Data Unit Session) corresponding to the slice to the DRB (Data Radio Bearer) and logical channels, thereby achieving high-priority scheduling of services in specific slices.

[0003] However, after different scheduling is implemented for services in different slices, the same processing method is still used for the transmission of each service during physical layer transmission.

[0004] Although the existing technology can realize the priority scheduling of services for specific slices through layer-by-layer mapping of slices, the physical layer transmission method after scheduling cannot be differentiated according to the service type of the slice. For example, some RBs (resource blocks) for high-reliability service scheduling require highly robust physical layer transmission, and the physical layer needs to perform a low-order MCS (Modulation and Coding Scheme) and a physical layer transmission scheme with a low number of streams; the RBs for large-bandwidth service scheduling require a physical layer transmission scheme with a high-order MCS and a high number of streams. However, in the existing technology, the physical layer does not differentiate the channel measurement and other processes on all RBs according to service requirements, and therefore cannot perform differentiated channel quality evaluation according to service requirements.

[0064] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0065] like Figure 1 As shown, an embodiment of the present invention provides a resource configuration method, which is applied to a network device, and the method includes:

[0066] Step 11, obtaining service type information of at least one data packet; the network device may be a base station, and the base station may obtain the service type information of the data packet from the core network, and specifically may receive the service type information of the data packet from the core network through RRC (radio resource control) signaling;

[0067] Step 12: Map the service type information to a physical layer, and configure a channel state information reference signal CSI-RS sending resource configuration information corresponding to the service type information for the terminal, wherein the CSI-RS sending resource configuration information is used for channel measurement;

[0068] Step 13: Send the CSI-RS transmission resource configuration information to the terminal. Here, the information may be sent to the terminal via RRC signaling or via MAC (Media Access Medium) layer signaling.

[0069] In this embodiment, by informing the physical layer of the service type (or the type of slice) to which the current data packet belongs, the network device and the terminal physical layer can use CSI-RS sending resources and feedback results adapted to the service requirements to measure the channel quality, thereby affecting the subsequent transmission strategy for the service data packet.

[0070] In an optional embodiment of the present invention, the service type information includes: a slice identifier of the network slice and / or service quality information of the QoS flow of the network slice. The identifier of the network slice may indicate the type of the network slice, and the service quality information of the QoS flow of the network slice may also indicate the type of the network slice.

[0071] In an optional embodiment of the present invention, in the above step 12, mapping the service type information to the physical layer includes:

[0072] Step 121, mapping the service type to the data transmission resource of the physical layer. Specifically, the upper layer of the base station maps the service type to the data transmission bearer of the physical layer. Thus, the physical layer can use the MCS level and / or the number of data streams adapted to the service type to transmit data on the data transmission bearer. Specifically, the MCS level and / or the number of data streams can be scheduled by the MAC layer.

[0073] In the above embodiment of the present invention, the CSI-RS sending resource configuration information includes at least one of the following:

[0074] Time domain resources of CSI-RS transmission resources of the serving cell and neighboring cells;

[0075] Frequency domain resources of the serving cell and neighboring cells;

[0076] The airspace resources and port numbers of the serving cell and neighboring cells.

[0077] Optionally, the time domain resources include a period, frame and symbol for sending CSI-RS;

[0078] The frequency domain resources include bandwidth and resource blocks for sending CSI-RS;

[0079] The spatial resources include the beam direction for sending CSI-RS, the horizontal / vertical width of the beam, the beam gain, and the updating frequency of the beam direction.

[0080] In an optional embodiment of the present invention, the resource configuration method may further include:

[0081] Step 14, receiving a channel measurement result sent by the terminal, where the channel measurement result is obtained by performing channel measurement according to the CSI-RS sending resource configuration information;

[0082] In this step, after receiving the CSI-RS sending resource configuration information, the terminal measures CQI and / or RI, etc. based on the information indicated by the CSI-RS sending resource, and reports the measurement result to the base station, which may be reported through RRC signaling;

[0083] Step 15: Perform data transmission on data transmission resources corresponding to the service type according to the channel measurement result.

[0084] The physical layer may use the MCS level and / or the number of data streams adapted 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.

[0085] For the sake of simplicity, a user having services concurrently in two different slices is taken as an example to illustrate the specific implementation method of the above embodiment, where network slice 1 is a large bandwidth data service and network slice 2 is a high reliability service. The scheduling priority of network slice 2 is higher than that of slice 1.

[0086] An implementation of the above embodiment includes:

[0087] Step 1: The gNodeB RRC (RRC of the base station) layer receives and identifies the slice identifiers of the two network slices and the service quality information of the QoS flow of each slice, and maps the service QoS flow to the DRB (data radio bearer) and logical channel, and implements the scheduling priority of network slice 2 over network slice 1 through the MAC layer of the base station;

[0088] Step 2: The base station maintains two sets of CSI-RS transmission resource configuration information. The first set of configuration information is applicable to channel measurement of large bandwidth services, and adopts low-density transmission period, transmission beams with narrow horizontal and vertical beam widths, and refreshing the transmission direction according to SRS measurement. The second set of configuration information is applicable to channel measurement of high-reliability services, and adopts high-density transmission period, transmission beams with wide horizontal and vertical beam widths, and a fixed limited number of transmission directions.

[0089] Step 3: The base station sends two sets of configuration information to the terminal, configures two sets of CSI-RS resources, and configures the associated service type message for each set of CSI-RS resources. The service type message may include but is not limited to the identifier of the network slice or the 5QI identifier that describes the service quality of the service. One implementation method of step 3 is to use the service type message adapted to the CSI-RS resource using the service type identifier when the base station configures multiple sets of CSI-RS resources for the terminal.

[0090] The specific message content of the business type message is as follows:

[0091]

[0092]

[0093] Among them, servicetypeindicator and servicetypeindicatorID may include but are not limited to a slice ID or a 5QI identifier describing the service quality of the service;

[0094] Step 4: The terminal maps the service type message in the CSI-RS configuration to the corresponding service requirements, and reports the corresponding measurement results such as CQI (channel quality information) and RI (rank). The measurement results of CQI may include, but are not limited to, mapping the service requirements to indicators such as spectrum efficiency, iBLER, and delay, and selecting a matching CQI-Table (CQI measurement results) for feedback; the measurement results of RI may include, but are not limited to, mapping the service requirements to indicators such as spectrum efficiency, iBLER, and delay, and selecting a matching RI for feedback.

[0095] Step 5: The network side transmits data in the RB (resource block) scheduled by network slice 1 according to CQI_1 and RI_1 reported by the terminal for network slice 1, and transmits data in the RB (resource block) scheduled by network slice 2 according to CQI_2 and RI_1 reported by network slice 2. Although the channel from the base station to the user does not change in a short time, CQI_1 and CQI_2, RI_1 and RI_2 are generally different due to the different channel quality measurement methods corresponding to slice 1 and slice 2.

[0096] In the above-mentioned embodiments of the present invention, by informing the physical layer of the service type message to which the currently scheduled data packet belongs (such as slice ID, 5QI service requirements corresponding to the service type, etc.), the physical layer can use CSI-RS sending resources and feedback results adapted to the service requirements to carry out channel quality measurement, thereby realizing the transmission of differentiated physical layer service data packets that match the service requirements.

[0097] like Figure 2 As shown, an embodiment of the present invention further provides a channel measurement method, which is applied to a terminal, and the method includes:

[0098] Step 21, receiving CSI-RS transmission resource configuration information sent by a network device, where the CSI-RS transmission resource configuration information is associated with service type information of at least one data packet;

[0099] Step 22, sending resource configuration information according to the CSI-RS, performing channel measurement, and obtaining a channel measurement result;

[0100] Step 23: Report the channel measurement result to the network device.

[0101] In this embodiment, the terminal receives CSI-RS transmission resources adapted to the service requirements, performs channel quality measurements, and then reports the measurement results 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 transmit the corresponding service data packets.

[0102] In an optional embodiment of the present invention, the service type information includes: a slice identifier of the network slice and service quality information of the QoS flow of the network slice. The identifier of the network slice can indicate the type of the network slice, and the service quality information of the QoS flow of the network slice can also indicate the type of the network slice.

[0103] In an optional embodiment of the present invention, the CSI-RS sending resource configuration information includes at least one of the following:

[0104] Time domain resources of CSI-RS transmission resources of the serving cell and neighboring cells;

[0105] Frequency domain resources of the serving cell and neighboring cells;

[0115] Specifically, the terminal maps the service type message in the CSI-RS configuration to the corresponding service requirements, and reports the corresponding measurement results such as CQI (channel quality information) and RI (rank). Among them, the measurement results of CQI may include but are not limited to mapping the service requirements to indicators such as spectrum efficiency, iBLER, and delay, and selecting a matching CQI-Table (CQI measurement results) for feedback; the measurement results of RI may include but are not limited to mapping the service requirements to indicators such as spectrum efficiency, iBLER, and delay, and selecting a matching RI for feedback.
