According to RAN #80 conference, Study Item (SI) project of Low-latency and Low latency communications (URLLC), version (Release)16, URLLC enhancement needs to pay attention to the following aspects: between different users, there is uplink transmission multiplexing (RAN1) between services with different delay and reliability requirements.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

Referring to fig. 2, fig. 2 is a flowchart illustrating an uplink transmission method according to a first embodiment of the present invention, where the method is applied to a terminal, and includes the following steps:

step S21: receiving first physical layer downlink control information sent by a base station;

step S22: determining a first physical resource set and a second physical resource set according to the first physical layer downlink control information;

step S23: and performing no data transmission on the first set of physical resources, and performing data transmission on the second set of physical resources.

According to the uplink transmission method provided by the embodiment of the invention, the first physical resource set and the second physical resource set are determined according to the received first physical layer downlink control information, data transmission is not carried out on the first physical resource set, and data transmission is carried out on the second physical resource set, so that the reliability of a service with high priority can be effectively ensured, and the resource allocation is more flexible and efficient.

For example, when the uplink eMBB service of the terminal 1 conflicts with the uplink URLLC service of the terminal 2, the base station may send the first physical layer downlink control information to the terminal 1 for eMBB service transmission to support the uplink URLLC service to seize part or all of the resources used by the eMBB service, and the eMBB service does not perform data transmission on the seized resources and performs transmission on other resources according to the indication of the first physical layer downlink control information. Therefore, the reliability of the URLLC service is effectively ensured, and the resource allocation is more flexible and efficient.

More specifically, referring to fig. 3, the base station sends physical layer downlink control information 31 to the UE1 in slot 1, where UL grant information in the physical layer downlink control information 31 is used to indicate that eMBB traffic of the UE1 performs uplink transmission on symbols 2 to 13 of slot 4. The UE1 receives the physical layer downlink control information 31 in slot 1, and determines that the uplink resource of the eMBB service of the UE1 is symbols 2 to 13 of slot 4. The base station sends physical layer downlink control information 32 to the UE2 in slot 2, where UL grant information in the physical layer downlink control information 32 is used to indicate that the URLLC service of the UE2 performs uplink transmission on symbols 4 to 7 of slot4, that is, uplink resources of the URLLC service of the UE2 are symbols 4 to 7 of slot 4. At this time, the eMBB traffic of the UE1 collides with the URLLC traffic of the UE 2. The base station sends first physical layer downlink control information 33 to the UE1 in slot3, and the UE1 receives the first physical layer downlink control information 33 and determines a first physical resource set for not sending eMBB data and a second physical resource set for sending eMBB data.

In some preferred embodiments of the present invention, step S22 includes:

Preferably, the second physical layer downlink control information is previous physical layer downlink control information with a same HARQ process number as that of the first physical layer downlink control information.

Also taking fig. 3 as an example, if the process number of the HARQ information of the first physical layer downlink control information 33 received by the UE1 in slot3 is the same as the process number of the HARQ information of the physical layer downlink control information 31 received in slot 1, the uplink resources (i.e., symbols 2 to 13 of slot 4) indicated in the second physical layer downlink control information 31 received in slot 1 are used as the third physical resource set 34 by the UE1 in the physical layer downlink control information 31 received in slot 1, the first physical layer downlink control information 33 received in slot3, and the process number of the HARQ information of the first physical layer downlink control information 33 received in slot 1.

Specifically, when the process number of the HARQ information of the first physical layer downlink control information is the same as the process number of the HARQ information of the previous physical layer downlink control information, and a New Data Indicator (NDI) field in the HARQ information of the first physical layer downlink control information is not inverted, it is determined that uplink transmission corresponding to the first physical layer downlink control information is retransmission, and the previous physical layer downlink control information is determined as the second physical layer downlink control information.

The NDI field is briefly described below.

For the transmission of dynamically scheduled Uplink Hybrid Automatic Repeat reQuest (HARQ) Information, if a User Equipment (User Equipment, UE, also called a terminal) receives Downlink Control Information (Downlink Control Information, abbreviated as PDCCH) scrambled by a Cell Radio Network Temporary Identifier (C-RNTI) and carried by a Physical Downlink Control Channel (PDCCH), and an ndi (new data indicator) field carried by the DCI is flipped over compared with a previous transmission of a corresponding HARQ process (process), the corresponding transmission of the Physical Uplink Shared Channel (PUSCH) is a new transmission; if the UE receives DCI which is scrambled by using the C-RNTI and is carried by the PDCCH, and an NDI field carried by the DCI is not inverted compared with the previous transmission of the corresponding HARQ process, the corresponding PUSCH transmission is self-adaptive retransmission; if the UE receives DCI carried by PDCCH scrambled using C-RNTI and the HARQ buffer (buffer) of the corresponding HARQ process is empty (i.e. transmitted for the first time using that HARQ process), the corresponding PUSCH transmission is a new transmission.

In this embodiment of the present invention, the dimensions of the first physical resource set, the second physical resource set, and/or the third physical resource set include all or one of the following: the time slot of the resource set, the number of occupied symbols, the position information of the start symbol, the number of occupied physical resource blocks (PRB for short), and the position information of the start PRB.

In the embodiment of the present invention, there are various ways to determine the first physical resource set and the second physical resource set, and the following examples are described below.

(1) Determination mode of first physical resource set

11) Is directly indicated by the first physical layer downlink control information.

In other preferred embodiments of the present invention, the first physical layer downlink control information includes: indication information of the first set of physical resources;

step S22 includes:

That is, the first set of physical resources may be indicated by the base station. The indication information of the first set of physical resources may be UL grant information.

Still taking fig. 3 as an example, the UE1 receives the physical layer downlink control information 31 at slot 1, and receives the first physical layer downlink control information 33 at slot3, where the first physical layer downlink control information 33 includes indication information of the first physical resource set, and the indication information indicates that the first physical resource set is symbols 4 to 7 of slot 4. The UE1 may determine the symbols 4-7 of slot4 as the first set of physical resources 36 according to the indication information of the first set of physical resources.

12) And directly determining the first physical resource set according to the third physical resource set.

The third physical resource set can be directly used as the first physical resource set, so that data transmission is not performed on the whole third physical resource set, and data transmission of a service with high priority is better ensured (for example, in a scenario of multiplexing of a URLLC service and an eMBB service, the eMBB service does not perform data transmission on the whole third physical resource set, so that reliability of the URLLC service is effectively ensured).

A subset of the third set of physical resources may also be determined as the first set of physical resources.

That is, the terminal does not perform data transmission on part or all of the resources in the third set of physical resources to determine the transmission of the traffic with high priority.

13) The first set of physical resources is implicitly determined from the second set of physical resources.

A subset of the third set of physical resources may be determined as the first set of physical resources based on offset information of the first set of physical resources relative to the second set of physical resources.

That is, the terminal may determine the second physical resource set first according to the received first physical layer downlink control information, and then implicitly determine the first physical resource set by the second physical resource set.

Wherein the offset information of the first set of physical resources relative to the second set of physical resources comprises at least one of:

Also for example, as shown in FIG. 3, the third set of physical resources 34 are symbols 2-13 of slot4, and the second set of physical resources 35 are symbols 4-7 of slot 5.

If the offset information of the first physical resource set relative to the second physical resource set is: the number of symbols contained in the first physical resource set is equal to the number of symbols contained in the second physical resource set; the offset value of the starting symbol of the first physical resource set in the time domain relative to the starting symbol of the second physical resource set in the time domain is one slot ahead (for example, one slot includes 14 symbols, i.e., 14 symbols ahead), and it can be determined that the symbols 4-7 of slot4 are the first physical resource set 36.

If the offset information of the first physical resource set relative to the second physical resource set is: the number of symbols contained in the first physical resource set is equal to the number of symbols contained in the second physical resource set; the offset value of the start symbol of the first physical resource set in the time domain relative to the start symbol of the second physical resource set in the time domain is 13 symbols ahead (in fig. 3, one slot includes 14 symbols), and it can be determined that the symbols 3-6 of the slot4 are the first physical resource set (not shown).

(2) Determining mode of second physical resource set

21) Is directly indicated by the first physical layer downlink control information.

Specifically, the first physical layer downlink control information may include: indication information of the second set of physical resources;

step S22 includes:

Wherein the indication information of the second set of physical resources may be UL grant information.

Still taking fig. 3 as an example, the indication information of the second physical resource set (i.e. the time-frequency domain allocation information of the second physical resource set) specifies symbols 4 to 7 of slot 5 as the second physical resource set 35, so that the symbols 4 to 7 of slot 5 can be directly determined as the second physical resource set 35 according to the indication information of the second physical resource set.

22) The second set of physical resources is implicitly determined from the first set of physical resources.

In some preferred embodiments of the present invention, step S22 includes:

Wherein the offset information of the second set of physical resources relative to the first set of physical resources comprises at least one of:

That is, the first set of physical resources may be determined first, and then the second set of physical resources may be determined according to the offset information of the second set of physical resources with respect to the first set of physical resources.

Still taking fig. 3 as an example, the first set of physical resources is symbols 4 to 7 of slot4, and the offset information of the second set of physical resources relative to the first set of physical resources is: the number of symbols contained in the second physical resource set is equal to the number of symbols contained in the first physical resource set; the offset value of the starting symbol of the second physical resource set in the time domain relative to the starting symbol of the first physical resource set in the time domain is delayed by one slot (for example, one slot includes 14 symbols, that is, 14 symbols are delayed); the frequency domain resources of the first set of physical resources are the same as the frequency domain resources of the second set of physical resources.

From the offset information of the second set of physical resources relative to the first set of physical resources and the first set of physical resources 36 (i.e., symbols 4-7 of slot 4), it may be determined that the second set of physical resources 35 are symbols 4-7 of slot 5.

If the offset value of the start symbol of the second set of physical resources in the time domain relative to the start symbol of the first set of physical resources in the time domain is 2 slots later, it can be determined that the second set of physical resources 35 is symbols 4-7 of slot 6.

23) And implicitly determining the second physical resource set according to the third physical resource set.

Step S22 includes:

and determining the third physical resource set according to the offset information of the second physical resource set relative to the third physical resource set.
