Detailed ways

In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the various embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in this application can be realized.

In the URLLC scenario shown in Figure 1, the base station sends downlink control information (Downlink Control Information, DCI) to the terminal through the Physical Downlink Control Channel (PDCCH), and through the Physical Downlink Shared Channel (PDSCH) ) Send a downlink data service to the terminal. The PDSCH demodulation information is carried in the DCI. For each packet of downlink data services, a corresponding DCI is required to instruct the terminal how to parse it.

In the URLLC scenario, in order to pursue low latency requirements, scheduling is usually small and frequent. In general, data services occupy the same slot in the time domain and can be scheduled multiple times. As shown in Figure 2, there are 14 symbols in a slot, and each packet of data services occupies 2 symbols, which can be scheduled 7 times in a slot. As shown in Figure 3, the base station sends 7 downlink data services to the terminal in the same slot. Correspondingly, 7 downlink control information needs to be sent. However, receiving and processing multiple downlink control information in a slot requires high chip processing capabilities of the terminal device. Currently, there are few terminals that support URLLC services, and there are currently no commercially available terminals that fully support URLLC services.

To solve the above problems, the first embodiment of the present application relates to a data service analysis method, which is applied to a terminal and includes: receiving control information, the control information carries demodulation information of the first data service, and the demodulation information To analyze the information required by the data service; according to the demodulation information of the first data service, the demodulation information of other data services in the same time slot as the first data service is determined, and the other data services are in the same time slot. It is arranged after the first data service in the time domain; and the other data service is analyzed according to the demodulation information of the other data service. This embodiment reduces the requirement for the chip processing capability of the terminal to implement the URLLC service, and the terminal device with limited chip processing capability can also implement the URLLC service.

The following specifically describes the implementation details of the data service analysis method of this embodiment. The following content is only provided for ease of understanding and is not necessary for implementing this solution.

The data service analysis method in this embodiment is shown in Figure 4:

Step 101: Receive control information, where the control information carries demodulation information of a first data service, and the demodulation information of the first data service is information required for analyzing the data service.

Specifically, the terminal receives control information through the physical downlink control channel, the control information carries demodulation information of the first data service, and the demodulation information is used to instruct the terminal to analyze the first data service in the physical downlink shared channel. Wherein, the demodulation information may include time domain information and frequency domain information of the first data service.

In this embodiment, the terminal can configure the control resource set (ControlResourceSet) and the search space resource (SearchSpace) resource set according to the pre-received radio resource control (Radio Resource Control, RRC) message, and specify according to the RRC message ControlResourceSet ID and SearchSpace ID used for URLLC services (the terminal can find the corresponding ControlResourceSet and SearchSpace resources in the resource set through this ID), or the ControlResourceSet ID and SearchSpace ID (for example, agreed upon with the base station) for the URLLC service. The resource with a good ID of 65535 is the resource used for the URLLC service), and the control information is parsed in the physical downlink control channel.

In addition, after receiving the control information in this step, it may further include: analyzing the first data service according to the demodulation information of the first data service.

Step 102: Determine the demodulation information of other data services in the same slot as the first data service according to the demodulation information of the first data service, and the other data services are arranged in the first data service in the time domain. After a data service.

Specifically, the terminal determines the demodulation information of other data services in the same slot as the first data service according to the demodulation information of the first data service carried in the control information. In this embodiment, the terminal can specifically use the preset relationship between the demodulation information of the first data service and the demodulation information of other data services, and infer other data services based on the demodulation relationship of the first data service. Demodulate information.

It is worth mentioning that for those control information that is parsed in the physical downlink control channel based on the ControlResourceSet ID and SearchSpace ID that are not used for URLLC services, the terminal does not need to determine the demodulation information of other data services, but only needs to carry it according to the control information. The demodulation information analyzes the corresponding data service.

Step 103: Analyze the other data services according to the demodulation information of the other data services.

Specifically, the terminal analyzes other data services in the physical downlink shared channel according to the demodulation information of other data services obtained in the previous step.

In an example, as shown in Figure 5, the base station sends 7 downlink data services to the terminal in the same slot, and the terminal determines the data services 2 to 2 according to the demodulation information of the data service 1 carried in the received control information 1. Demodulation information of data service 7.

Compared with the prior art, in this embodiment, the terminal receives the control information carrying the demodulation information of the first data service, and determines other data in the same slot as the first data service according to the demodulation information of the first data service. The demodulation information of the service is used to analyze other data services based on the demodulation information of other data services. The demodulation information of other data services in the same slot is determined by the demodulation information of the first data service, so that the terminal can analyze the multi-packet data services in the same slot after receiving the control information once, so that the chip processing capability is not high and does not support the A terminal that receives control information multiple times in a slot can implement the URLLC service, which reduces the requirement of the URLLC service on the chip processing capability of the terminal.

The second embodiment of the present application relates to a data service analysis method. The second embodiment is roughly the same as the first embodiment, but the difference is that in this embodiment, the demodulation information is specifically the start symbol of the data service, the number of symbols occupied, the start frequency domain position, and the frequency domain resource block. This embodiment provides a specific method for determining demodulation information of other data services based on the demodulation information of the first embodiment.

The starting frequency domain position and the number of frequency domain resource blocks.

Step 202: According to the start symbol and the number of symbols occupied by the first data service, determine the start symbol and the number of symbols occupied by other data services in the same slot as the first data service.

Specifically, the terminal determines the time domain information of other data services in the same slot as the first data service according to the time domain information (including the start symbol and the number of symbols occupied) of the first data service carried in the control information. In this embodiment, the number of symbols occupied by the first data service is equal to the number of symbols occupied by each data service in other data services, and the data services in the slot are continuously arranged in the time domain. Therefore, based on the start symbol and the number of symbols occupied by the first data service, the terminal can infer the start of other data services that are in the same slot as the first data service and are arranged after the first data service in the time domain. The starting symbol and the number of symbols occupied.

For example, as shown in Figure 7, data service 2 is next to data service 1 (that is, the first data service) in the time domain, and it can be determined that the start symbol of data service 2 is located at the first symbol after the end symbol of data service 1. At the same time, the number of symbols occupied by data service 2 is the same as the number of symbols occupied by data service 1. In FIG. 7, the end symbol of data service 1 is symbol 1, and the start symbol of data service 2 is symbol 2. The number of symbols occupied by data service 2 is the same as the number of symbols occupied by data service 1, and both are 2. By analogy, the start symbols and the number of symbols occupied by the remaining packets of data services in the same slot can be inferred.

Step 203: Determine the starting frequency domain positions and frequency domain resources of other data services in the same slot as the first data service according to the starting frequency domain position and the number of frequency domain resource blocks of the first data service The number of blocks.

Specifically, according to the frequency domain information of the first data service (including the starting frequency domain position and the number of frequency domain resource blocks) carried in the control information, the terminal determines the data service of other data services in the same slot as the first data service. Frequency domain information. In this embodiment, the positions of the first data service and other data services in the frequency domain are the same, that is, the starting frequency domain positions and the number of frequency domain resource blocks of the first data service and other data services are the same.

It should be noted that in this embodiment, step 202 is the step of determining the start symbol and the number of symbols occupied by other data services, and step 203 is the step of determining the start frequency domain position and the number of frequency domain resource blocks of other data services. The sequence of steps is not limited. In practical applications, step 203 can be performed first, and then step 202 can be performed, or step 202 and step 203 can be performed at the same time.

Step 204: Analyze the other data services according to the demodulation information of the other data services.

Specifically, according to the start symbol, the number of symbols occupied, the start frequency domain position, and the number of frequency domain resource blocks of each other data service determined in the above steps, other data services are analyzed in the physical downlink shared channel.

Compared with the prior art, in this embodiment, the terminal receives control information, which carries the time domain information and frequency domain information of the first data service, where the time domain information includes the start symbol and the number of symbols occupied, The frequency domain information includes the starting frequency domain position and the number of frequency domain resource blocks.
