Description

Data indication method and equipment

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a data indication method and device.

Background

Currently in the discussion regarding the fifth Generation mobile communication system (5G), there may be three scenarios: enhanced Mobile BroadBand (eMBB), high-reliability Low Latency Communication (URLLC), and large-scale Internet of things Communication (mMTC). The data of the three different scenarios as above need to multiplex radio resources for transmission.

The punching multiplexing technology can realize multiplexing of time-frequency resources of eMBB and URLLC, so that the time-frequency resources are utilized more efficiently to transmit data. The puncturing multiplexing technique means that when URLLC data is to be transmitted and all time-frequency resources in the current transmission period have been scheduled, URLLC data can occupy the time-frequency resources already allocated to the eMBB data for transmission, and the eMBB data that would have been transmitted on the occupied time-frequency resources will not be transmitted any more. The method provides opportunities for URLLC data transmission, ensures low delay performance of the URLLC data, and influences eMBB data transmission. Because there are some resources in the time-frequency resources used for transmitting the eMBB data to carry URLLC data, reception of the eMBB data may be in error. Therefore, the base station needs to notify the receiving terminal of the eMBB data, where the received eMBB data includes URLLC data and is located at which time-frequency positions, so that the terminal receiving the eMBB data can remove the data to ensure that the eMBB data is not affected by the data. This process is called puncturing multiplexing indication.

In order to guarantee the high reliability requirement of URLLC data, a continuous transmission technique may be used for the transmission of URLLC data. As shown in fig. 1, the continuous transmission technique means that initial transmission and retransmission of URLLC data are performed continuously in a period of time, and a transmitting end does not need to trigger retransmission based on Negative Acknowledgement (NACK). The number of consecutive transmissions may be fixed or dynamically configurable. Under the puncturing multiplexing mechanism, when the URLLC data adopts a continuous transmission technology, a situation that the URLLC data continuously occupies time-frequency resources of the eMBB data may occur.

In the prior art, after puncturing multiplexing occurs, a base station notifies a terminal receiving the eMBB data of a time-frequency position of URLLC data included in the received eMBB data through a specific notification message, for example, Downlink Control Information (DCI). In the scenario of consecutive transmission of URLLC data, a special field needs to be used in DCI to indicate the time-frequency position of each transmission, which may cause higher bit overhead to the notification message, and the overhead may increase as the number of consecutive transmissions of URLLC data increases.

Disclosure of Invention

The application provides a data indication method and equipment, which are used for reducing bit overhead and saving resources.

The embodiment of the application provides a data indication method, which comprises the following steps:

The relationship between the initial frequency domain positions of each transmission can be in other forms, the method is not limited in the application, and the relationship between the frequency domain positions of each transmission only needs to be sent to the terminal, so that the problem of high cost caused by the fact that information indicating the frequency domain positions needs to be sent in each transmission is solved.

In the following embodiments, the base station is used to refer to the wireless access device in the above, which is not limited in this application.

Fig. 3 shows a schematic flowchart of a data indication method provided by an embodiment of the present application. The method is performed by a base station and a terminal, and the present invention is not limited thereto.

S301, a base station sends data to a terminal, wherein the data comprises eMBB data and URLLC data;

and the base station allocates resources for the eMMC data to be transmitted, and when the URLLC data to be transmitted reaches the base station and is ready to be transmitted and the time-frequency resources in the current transmission period (in the eMMC data transmission period) are scheduled, the base station can transmit the URLLC data by using part of the time-frequency resources allocated to the eMMC data.

S302, the base station sends information for indicating the initial transmission time-frequency position of the URLLC data and information for indicating the relationship between the frequency domain positions of each transmission of the URLLC data to the terminal.

Therefore, for the base station, the base station sends information for indicating the relationship between the initial transmission time-frequency position of the URLLC data and the time-frequency position of each time of URLLC data transmission to the terminal, so that the terminal can determine the time-frequency position of the URLLC data based on the indication information, thereby avoiding the problem of overlarge cost caused by the need of indicating the time-frequency position of each time of URLLC data transmission and achieving the effect of saving resources.

S303, the terminal determines the time-frequency position of each transmission of the URLLC data based on the information which is sent by the base station and used for indicating the initial transmission time-frequency position of the URLLC data and the information which is used for indicating the relationship between the frequency-domain positions of each transmission of the URLLC data.

It should be noted that S303 is optional compared to the previous step.

Further, the following embodiments are specific descriptions of related steps of the embodiment shown in fig. 3, and specific contents of the related steps between the embodiments in the present application may be referred to one another, which is not described herein again.

Fig. 4 shows a schematic flow chart of a data indication method.

S401, the base station distributes time frequency resources for eMBB data to be sent.

The time frequency resource is used for sending eMBB data.

S402, the base station maps URLLC data to be sent to partial time-frequency resources which are distributed for sending eMBB data.

The URLLC data to be transmitted reaches the base station to be ready for transmission, and the time-frequency resources in the current transmission period (in the eMBB data transmission period) are already scheduled, at this time, the base station may use part of the time-frequency resources already allocated to the eMBB data to transmit the URLLC data, as shown in fig. 5.

As shown in fig. 5, the base station transmits URLLC data using a part of time-frequency resources already allocated to the eMBB data 1, where the URLLC data includes initial transmission data and retransmission data, including initial transmission data, retransmission data 1, retransmission data 2, and retransmission data 3 in fig. 5.

The URLLC data to be sent may arrive in the process of transmitting the eMBB data, or may arrive before the eMBB data is transmitted, which is not limited in the present application.

Optionally, the URLLC data to be sent may include URLLC initial transmission data and retransmission data.

And S403, the base station sends the eMBB data to be sent to the terminal.

Because the time-frequency resource part of the eMB data is occupied by the URLLC data, the eMB data received by the eMB terminal contains the URLLC data.

And S404, the base station sends the relation between the initial transmission time frequency position of the URLLC data and the frequency domain position of each time of URLLC data transmission to the terminal through the DCI.

The URLLC data is the above URLLC data to be transmitted.

The DCI may be sent in the next eMBB transmission period, or may be sent in the subsequent eMBB transmission period, for example, the DCI may be sent when the eMBB data is retransmitted, which is not limited in this application.

Specifically, one field may be used in the DCI to indicate the time-frequency location of initial transmission of URLLC data, and another field may be used to indicate the relationship between the frequency-domain locations of respective URLLC data transmissions. The relationship between the frequency domain positions of the URLLC data transmissions may also be indicated by other information, which is not limited in this application.

It should be noted that, the continuously transmitted URLLC data occupies time domain resources of continuous and same size in time domain, and the terminal can determine the time-frequency position of each URLLC data transmission by combining the relation between the frequency domain positions of the above-mentioned transmitted indications of each URLLC data transmission. Of course, the time domain resource occupied by the continuously transmitted URLLC data may be in other forms and sizes, which is not limited in this application.

S405, the terminal determines the time-frequency position of each transmission of the URLLC data based on the relation between the initial transmission time-frequency position of the URLLC data in the DCI and the frequency-domain position of each transmission of the URLLC data.

And the terminal removes the URLLC data from the eMBB data, so that the influence on the eMBB data is avoided.

Optionally, the base station may need to retransmit the eMBB data subsequently to supplement the part of the eMBB data replaced by the URLLC data.

Based on the method provided by the embodiment of the invention, the base station sends the information for indicating the relationship between the initial transmission time-frequency position of the URLLC data and the frequency-domain position of each time of URLLC data transmission to the terminal, and the terminal can determine the time-frequency position of each time of URLLC data transmission based on the indication information, thereby avoiding the problem of overlarge cost caused by the need of indicating the time-frequency position of each time of URLLC data transmission and achieving the effect of saving resources.

Fig. 6 shows a schematic flow chart of a data indication method.

S601, the base station informs all terminals receiving eMMC data in the cell through a system message, and the relation of frequency domain positions of the URLLC data transmission is carried out for each time.

The System message may be a Master Information Block (MIB) or a System Information Block (SIB), and may also send the relationship of the frequency domain position of each URLLC data transmission through other messages, which is not limited in this application.

And each URLLC data transmission refers to URLLC data which is continuously transmitted in the puncturing multiplexing.

The relationship between the frequency domain positions of the URLLC data transmissions may be statically configured, or configured periodically semi-statically, or triggered by the base station based on certain conditions.

Specifically, a field is used in the system message MIB or SIB to indicate the relationship between the time-frequency positions of each transmission of URLLC data.

S602, the base station allocates time frequency resources for eMBB data to be sent.

S603, the base station maps the URLLC data to be sent to a part of time-frequency resources which are already allocated for sending the eMBB data.

Reference may be made specifically to fig. 5 and the related description of S402.

And S604, the base station sends the eMBB data to be sent to the terminal.

And S605, the base station sends the initial transmission time-frequency position of the URLLC data to the terminal through the DCI.

Specifically, a field is used in DCI to indicate the time-frequency position of initial transmission of URLLC data.

And S606, the terminal determines the time-frequency position of each transmission of the URLLC data based on the obtained relation of the frequency-domain positions of the URLLC data of each transmission and the time-frequency position of the initial transmission of the URLLC data.

Specifically, based on the above embodiment, how to indicate the relationship of the frequency domain position of URLLC data transmission, there may be the following form. It should be noted that each transmission of URLLC data may occupy time domain resources of continuous and same size in the time domain, which is not described in detail below. Certainly, each transmission of URLLC data may occupy time-frequency resources of other forms and sizes in the time domain, and the indication of the time-domain position of each URLLC data transmission may be configured in the terminal in advance or sent to the terminal by the base station, which is not limited in this application.

Optionally, as shown in fig. 7, the information indicating the relationship between the frequency domain positions of the URLLC data transmissions, specifically, the information indicating that the start positions of the URLLC data transmissions on the frequency domain are the same. Therefore, the frequency domain starting position of the subsequent transmission can be known only by knowing the starting frequency domain position of the initial transmission of the URLLC data. In the present application, the time-frequency resource occupied by each transmission may be different in size, and therefore, in this embodiment, only the start positions of the limited frequency domains are the same, but the end positions of the limited frequency domains are also the same.

Optionally, as shown in fig. 8, the information for indicating the relationship between the frequency domain positions of the URLLC data transmissions of each time, specifically, the information for indicating that the URLLC data transmissions of each time are based on a unidirectional fixed frequency shift in the frequency domain, that is, the start frequency domain positions of two adjacent transmissions differ by a fixed frequency interval in a single direction.

Optionally, as shown in fig. 9, the information used for indicating the relationship between the frequency domain positions of the respective URLLC data transmissions is specifically used for indicating that the difference between the start frequency domain positions of two adjacent URLLC data transmissions in the respective URLLC data transmissions is a fixed frequency interval or a negative interval, that is, the start frequency domain positions of two adjacent URLLC data transmissions may be a frequency domain interval in which the start frequency domain position of the previous transmission is more fixed than the start frequency domain position of the next transmission, or a frequency domain interval in which the start frequency domain positions of two adjacent URLLC data transmissions are less fixed, and the frequency domain start positions of the two transmissions separated by one transmission are the same.

In the embodiments provided in fig. 10, 11, and 12 below, the information that is sent by the base station to the terminal and used for indicating the initial transmission time-frequency position of the URLLC data may be the number of the initial transmission time-frequency position of the URLLC data, and the information that is used for indicating the relationship between the frequency-domain positions (or time-frequency positions) of the URLLC data for each transmission includes the relationship between the numbers of the frequency-domain positions (or time-frequency positions) of the URLLC data for each transmission, where these numbers have a mapping relationship with pre-configured time-frequency resources or pre-configured frequency-frequency resources, the base station may first inform the relationship between the terminal numbers and resources, and after receiving the corresponding numbers and the relationship between the numbers of the frequency-domain positions of the URLLC data for each transmission, the terminal may determine the time-frequency resources occupied by each URLLC data transmission.

Optionally, as shown in fig. 10, the base station pre-configures a part of transmission time-frequency resources for each URLLC transmission period, so as to transmit URLLC data. If there is URLLC data transmission in a certain URLLC transmission period, it will occupy the pre-configured time frequency resource, and will not occupy other time frequency resources. The preconfigured resources within each URLLC transmission period are numbered (#1, #2, …) to refer to the respective preconfigured resources. The base station sends the relation between the serial number and the preconfigured resource to the terminal, and further, the base station sends the serial number of the initial transmission time-frequency position of the URLLC data and the relation between the resource serial numbers of the URLLC data transmission for each time, for example, in this embodiment, the frequency domain resource serial number of the initial transmission data of the URLLC sent by the base station to the terminal is #1, and the serial number of the frequency domain position of the URLLC data transmission for each time is the same as the initial transmission serial number, then the terminal can determine the time-frequency resource occupied by each transmission of the URLLC data, that is, each transmission of the URLLC data uses the preconfigured resource with the serial number of #1, based on the indication that #1 and the serial number of the frequency domain position of each URLLC data transmission for each time are the same.

Optionally, as shown in fig. 11, the base station pre-configures a part of transmission time-frequency resources for each URLLC transmission period, so as to transmit URLLC data. The relationship between the pre-configured resource numbers used by the base station for each transmission of URLLC data is sequentially increasing (e.g., #1, #2, #3, #1) or sequentially decreasing (e.g., #3, #2, #1, # 3). And after the maximum mark number is reached by sequential increment, the system returns to the initial number #1, and the process is circulated. Similarly, when the number is sequentially decreased to the minimum number #1, the number is returned to the maximum number. The base station firstly sends the relation between the pre-configured resources corresponding to each number to the terminal, the subsequent base station sends information for indicating that the number of the time-frequency position of the initial transmission and the number of the frequency-domain resource of each time of data transmission of the URLLC are ascending or descending to the terminal, and the terminal can deduce the resource number used by the subsequent transmission through the defined resource number relation used by each transmission. As shown in fig. 11, the initial transmission data occupies the time-frequency resource corresponding to #1, the retransmission data 1 occupies the time-frequency resource corresponding to #2, the retransmission data 2 occupies the time-frequency resource corresponding to #3, the retransmission data 3 occupies the time-frequency resource corresponding to #1, the #1, #2 and #3 correspond to time-frequency resources of different frequency domains, the base station sends information indicating that the frequency domain position number of the initial transmission data of the URLLC data is #1 and the frequency domain position number of each transmission data of the URLLC data is incremented to the terminal, and the terminal determines the time-frequency resource corresponding to each transmission of the URLLC data based on the relationship between the number and the time-frequency position number of each transmission data.

Optionally, as shown in fig. 12, the base station pre-configures a part of transmission time-frequency resources for each URLLC transmission period, where the transmission time-frequency resources are used for transmitting URLLC data, numbers the pre-configured time-frequency resources, and sends a relationship between the numbers and the frequency-domain resources to the terminal. As shown in fig. 12, the preconfigured resource numbers of two adjacent transmissions in each transmission of URLLC data by the base station differ by 1, while the preconfigured resource numbers used for two transmissions that are separated by one transmission are the same. As shown in fig. 12, the pre-configured resource numbers (#1, #2, #1, #2) used for each transmission of URLLC data alternate between #1 and # 2. Also, (#2, #1, #2, #1) is possible. The difference between the two is that the number of the pre-configured resource used by retransmission 1 is 1 more or 1 less than that of initial transmission, the base station further sends the number of the initial transmission data frequency domain position of the URLLC data and the relation between the numbers of the frequency domain positions of the data transmitted for each time to the terminal, and the terminal determines the time-frequency resource corresponding to each transmission of the URLLC data based on the number.

Therefore, the base station only needs to send the number used for indicating the initial transmission time-frequency position of the URLLC data and the relation between the numbers of the frequency-domain positions of the URLLC data in each transmission to the terminal, the terminal can determine the time-frequency resources occupied by each transmission of the URLLC data based on the relation between the numbers, and the terminal further removes the URLLC data from the eMBB data, so that the influence on the eMBB data is avoided.

Based on the same technical concept in the above embodiments, the embodiments of the present application further provide a base station.
