Description

Communication method and related device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communications method and a related device.

Background

With the development of the fifth generation (the 5th generation,5G) communication technology, in the current communication system, reliability of service can be achieved by the following mechanisms, including: hybrid automatic repeat request (hybrid automatic repeat request, HARQ) or automatic repeat request (automatic repeat request, ARQ).

In a network device, only one type of data can be scheduled when a certain terminal device is scheduled at the same scheduling time. For example: with respect to the terminal device 1, only the primary transmission data or the retransmission data can be scheduled at the time of scheduling of the transmission time interval (transmission time interval, TTI) 1. The primary transmission data refers to data which is not modulated; the retransmission data refers to the scheduled data, but the HARQ feedback state of the data is non-acknowledgement (NACK).

Therefore, when the network device needs to schedule the primary transmission data and the retransmission data at a certain scheduling time, the retransmission data is scheduled at the current scheduling time, and the primary transmission data is scheduled at the next scheduling time. Causing an increase in the transmission delay of the primary data.

Disclosure of Invention

In a first aspect, an embodiment of the present application provides a communication method, which is characterized in that:

the network equipment determines first data and second data which are scheduled on a first time domain resource, wherein the first data are data which are transmitted for the first time, and the second data are data which are retransmitted;

the network device sends first indication information and second indication information to the terminal device,

wherein the first indication information indicates a first process to schedule the first data,

The second indication information indicates that a second process schedules the second data,

the first process is a hybrid automatic repeat request (HARQ) process, the second process is a HARQ process, the time domain resource used by the first process is the first time domain resource, and the time domain resource used by the second process is the first time domain resource.

Specifically, the first data and the second data may be uplink data (i.e., data sent by the terminal device to the network device); the first data and the second data may also be downlink data (i.e. data sent by the network device to the terminal device). It should be noted that, in the embodiment of the present application, the resource granularity of the first time domain resource may be a slot (slot), a sub-slot (sub-slot), or other resource granularities such as a symbol, which is not limited in the embodiment of the present application.

In the embodiment of the application, network equipment determines first data and second data which are scheduled on a first time domain resource, wherein the first data are data which are transmitted for the first time, and the second data are data which are retransmitted; the network device sends first indication information and second indication information to the terminal device, wherein the first indication information indicates a first process to schedule first data, the second indication information indicates a second process to schedule second data, the first process is a hybrid automatic repeat request (HARQ) process, the second process is a HARQ process, time domain resources used by the first process are first time domain resources, and time domain resources used by the second process are first time domain resources. By the method, the data transmitted for the first time and the data retransmitted can be scheduled in the same time domain resource, so that the waiting time delay of the data transmitted for the first time is reduced.

In a possible implementation manner of the first aspect, the network device obtains first data, and the first data is from the core network. For example: the first data is downlink data which is transmitted to the terminal equipment and is issued by the core network. After the network device acquires the first data, the network device stores the first data in a memory, where the memory is used to store data of the radio link control RLC layer. The first data is first transmitted data, or data that is first transmitted by the network device to the terminal device, and may also be referred to as new transmitted data (or newly transmitted data).

Before the network device sends the first data to the terminal device, i.e. when the first data is still stored in the memory. The network device receives first feedback information from the terminal device, the first feedback information being a non-acknowledgement (NACK) feedback or a discontinuous transmission (discontinuous transmission, DTX) feedback of the third data.

The network device determines, according to the first feedback information, that the third data sent by the network device to the terminal device needs to be retransmitted (retransmission may be abbreviated as retransmission in the embodiment of the present application). For convenience of explanation, in the embodiment of the present application, the data to be retransmitted corresponding to the third data is referred to as second data. The time domain resource allocated by the network device for the second data is a first time domain resource (i.e. the time domain resource to be scheduled for the second data is the first time domain resource).

When the first data is stored in the memory and the network device receives the first feedback information from the terminal device, the network device determines to schedule the first data and the second data on the first time domain resource in order to reduce the latency of the first data.

In a possible implementation manner of the first aspect, the network device sends a first transport block to the terminal device using the first time domain resource, the first transport block being associated with the first process, the first transport block carrying the first data;

and the network equipment uses the first time domain resource to send a second transmission block to the terminal equipment, wherein the second transmission block is associated with the second process, and the second transmission block carries the second data.

In a possible implementation manner of the first aspect, the network device receives a buffer status report (Buffer Status Report, BSR) from the terminal device, the buffer status report indicating that the first time domain resource has the first data to be scheduled. In other words, the BSR from the terminal device indicates that the network device needs to schedule the first data from the terminal device at the first time domain resource.

Optionally, the network device determines, by means of prediction, that there is first data to be scheduled on the first time domain resource. For example: the sending of data by the terminal device to the network device may have a periodic law. Therefore, the network device can predict that the first data to be scheduled exists on the first time domain resource according to the statistical result of the data received by the terminal device within a period of time. That is, on the first time domain resource, the terminal device may send the first data to the network device. The network device needs to reserve a first delay resource for the first data.

The network device receives third data from the terminal device, and then the network device demodulates and decodes the third data.

When the check result of the third data is an error, for example, a cyclic redundancy check (cyclic redundancy check, CRC) error. The network device considers that the third data has a transmission error. The network device needs the terminal device to retransmit the third data. In the embodiment of the present application, the third data that needs to be retransmitted by the terminal device is referred to as second data.

Since the network device has not scheduled the first data from the terminal device (the time domain resource to be scheduled of the first data is the first time domain resource), and the network device determines that the third data needs to be retransmitted, i.e. the network device needs to schedule the second data to the terminal device. In order to reduce the latency of the first data, the network device determines that the first time domain resource has the first data and the second data that need to be scheduled.

In a possible implementation manner of the first aspect, the network device uses the first time domain resource to schedule a first transport block from the terminal device, the first transport block carrying the first data, the first transport block being associated with the first process;

the network device uses the first time domain resource to schedule a second transport block from the terminal device, the second transport block carrying the second data, the second transport block being associated with the second process.

In a possible implementation manner of the first aspect, the first indication information and the second indication information are downlink control information DCI.

In a second aspect, an embodiment of the present application provides a communication method, which is characterized in that the method includes:

the network device sends third indication information to the terminal device, the third indication information indicates a third process to schedule fourth data, the fourth data is recombined data of the first data and the second data, and time domain resources used by the third process are the first time domain resources.

In the embodiment of the application, network equipment determines first data and second data which are scheduled on a first time domain resource, wherein the first data are data which are transmitted for the first time, and the second data are data which are retransmitted; the network device sends third indication information to the terminal device, the third indication information indicates a third process to schedule fourth data, time domain resources used by the third process are the first time domain resources, and the fourth data are recombined data of the first data and the second data. According to the method, the reorganized data is obtained according to the data transmitted for the first time and the data retransmitted, and the data transmitted for the first time and the data retransmitted for the second time can be scheduled in the same time domain resource by transmitting the reorganized data, so that the waiting time delay of the data transmitted for the first time is reduced.

In a possible implementation manner of the second aspect, the network device determines, according to the first data, a radio link control service data unit RLC SDU corresponding to the first data;

the network equipment determines the RLC SDU corresponding to the second data according to the second data;

and the network equipment is used for recombining the RLC SDU corresponding to the first data and the RLC SDU corresponding to the second data to obtain fourth data, wherein the fourth data is a radio link control protocol data unit (RLC PDU).

Specifically, the network device allocates related resources for the fourth data so that the fourth data can be transmitted at the same time in the medium access control (medium access control, MAC) layer. Since the fourth data has a larger data amount than the first data or the second data. Thus, the associated resources allocated by the network device for the fourth data are also larger than the associated resources allocated by the network device for the first data or the second data. For example: the bandwidth allocated for the fourth data is greater than the bandwidth allocated for the first data or the second data.

In a possible implementation manner of the second aspect, the network device obtains first data, and the first data is from the core network. For example: the first data is downlink data which is transmitted to the terminal equipment and is issued by the core network. After the network device acquires the first data, the network device stores the first data in a memory, where the memory is used to store data of the radio link control RLC layer. The first data is first transmitted data, or data that is first transmitted by the network device to the terminal device, and may also be referred to as new transmitted data (or newly transmitted data).

In a possible implementation manner of the second aspect, the network device sends a third transport block to the terminal device, where the third transport block is associated with the third process, a scheduling time of the third transport block is the first time domain resource, and the third transport block carries the fourth data.

In one possible implementation manner of the second aspect, the network device receives a buffer status report (Buffer Status Report, BSR) from the terminal device, the buffer status report indicating that the first data that needs to be scheduled exists for the first time domain resource. In other words, the BSR from the terminal device indicates that the network device needs to schedule the first data from the terminal device at the first time domain resource.

In a possible implementation manner of the second aspect, the network device schedules a third transport block from the terminal device, where a scheduling time of the third transport block is the first time domain resource, and the third transport block carries the fourth data.

Currently, when the network device needs to schedule the primary transmission data and the retransmission data at a certain scheduling time, the network device schedules the retransmission data at the current scheduling time and schedules the primary transmission data at the next scheduling time. For example, downlink data is taken as an example. Referring to fig. 5, fig. 5 is a schematic diagram of scheduling of primary transmission data and retransmission data. When the memory of the network device stores the primary data (i.e. the data that is not scheduled), the network device determines that there is retransmission data (e.g. the network device receives NACK feedback from the terminal device for a certain downlink data). The network device schedules retransmission data (transport block (TB) 0) on slot (slot) 0 and the network device schedules primary transmission data (TB 2) on the next scheduling instant (e.g., slot 2). The network device causes an increase in the transmission delay of the primary data. When there are no available time domain resources in the transmission time interval (transmission time interval, TTI) of the scheduled retransmission data, the network device needs to find available time domain resources in the next TTI for scheduling the primary transmission data. The transmission delay of the primary data is further deteriorated.

Based on this, the embodiment of the application provides a communication method, in which a network device determines first data and second data scheduled on a first time domain resource, where the first data is first transmitted data, and the second data is retransmitted data; the network device sends first indication information and second indication information to the terminal device, wherein the first indication information indicates a first process to schedule first data, the second indication information indicates a second process to schedule second data, the first process is a hybrid automatic repeat request (HARQ) process, the second process is a HARQ process, time domain resources used by the first process are first time domain resources, and time domain resources used by the second process are first time domain resources. By the method, the data transmitted for the first time and the data retransmitted can be scheduled in the same time domain resource, so that the waiting time delay of the data transmitted for the first time is reduced.

Next, referring to fig. 3, fig. 3 is a schematic diagram of an embodiment of a communication method according to an embodiment of the present application. The communication method provided by the embodiment of the application comprises the following steps:

301. the network device determines to schedule the first data and the second data on the first time domain resource.

In step 301, the network device determines first data and second data that need to be scheduled on a first time domain resource. The first data and the second data may be uplink data (i.e. data sent by the terminal device to the network device); the first data and the second data may be downlink data (i.e., data transmitted from the network device to the terminal device), which will be described below.

(A) When the first data and the second data are downlink data, the network device determines that the first data and the second data need to be scheduled on the first time domain resource by the following method:

the network device obtains first data, the first data coming from the core network. For example: the first data is downlink data which is transmitted to the terminal equipment and is issued by the core network. After the network device acquires the first data, the network device stores the first data in a memory, where the memory is used to store data of the radio link control RLC layer. The first data is first transmitted data, or data that is first transmitted by the network device to the terminal device, and may also be referred to as new transmitted data (or newly transmitted data).

(B) When the first data and the second data are uplink data, the network device determines that the first data and the second data need to be scheduled on the first time domain resource by:

optionally, the network device receives a buffer status report (Buffer Status Report, BSR) from the terminal device, the buffer status report indicating that the first time domain resource has the first data to be scheduled. In other words, the BSR from the terminal device indicates that the network device needs to schedule the first data from the terminal device at the first time domain resource.

It should be noted that, in the embodiment of the present application, the resource granularity of the first time domain resource may be a slot (slot), a sub-slot (sub-slot), or other resource granularities such as a symbol, which is not limited in the embodiment of the present application.

302. The network device sends first indication information and second indication information to the terminal device, wherein the first indication information indicates the first process to schedule first data, the second indication information indicates the second process to schedule second data, and time domain resources used by the first process and the second process are first time domain resources.

In step 302, the network device selects two processes from idle (or available) HARQ processes of the terminal device as a first process and a second process, respectively. The first process is used for scheduling first data, and the second process is used for scheduling second data. The time domain resource used by the first process is a first time domain resource, and the time domain resource used by the second process is a first time domain resource.

Specifically, the first indication information carries a sequence number of the first process, for example: HARQ sequence number of the first process. The first process includes indication information of the first transport block such that the first data may be carried at the first transport block. Similarly, the second instruction information carries a sequence number of the second process, for example: HARQ sequence number of the second process. The second process includes indication information of the second transport block such that the second data may be carried in the second transport block.

Illustratively, the first indication information and the second indication information are downlink control information (downlink control information, DCI).

In a possible implementation manner, the first indication information and the second indication information sent by the network device to the terminal device are carried in the same signaling.

In another possible implementation manner, the network device sends the first indication information and the second indication information to the terminal device through different signaling respectively.

303. The first transport block carries first data and the second transport block carries second data.

In step 303, description is made with respect to uplink data and downlink data, respectively.

(A) When the first data and the second data are downlink data:

specifically, the network device uses the first time domain resource to schedule a transport block to the terminal device, where the first transport block is associated with the first process, and the first transport block carries the first data; the network device uses the first time domain resource to schedule a second transport block to the terminal device, the second transport block is associated with the second process, and the second transport block carries the second data.

(B) When the first data and the second data are uplink data:

Specifically, the network device uses the first time domain resource to schedule a first transport block from the terminal device, where the first transport block carries the first data, and the first transport block is associated with the first process; the network device uses the first time domain resource to schedule a second transport block from the terminal device, the second transport block carrying the second data, the second transport block being associated with the second process.

Fig. 6 is a schematic diagram of data transmission according to an embodiment of the present application, as shown in fig. 6. The network device is taken as an example to process the primary transmission data 1 and the retransmission data 1. When the network device determines that the data is Slot0, the primary transmission data 1 is stored in the memory, and the network device receives NACK feedback of TB01 corresponding to the retransmission data 1. Thus, in this TTI, there is a need for simultaneous transmission of primary data 1 and retransmission data 1. The network device selects two HARQ processes from the idle HARQ processes of the terminal device, and the two HARQ processes are respectively used for scheduling the primary transmission data 1 and the retransmission data 1. So that primary transmission data 1 is transmitted on TB00 and retransmission data 1 is transmitted on TB 01. Since the transmission time of the TB00 and the TB01 is Slot0, the simultaneous transmission of the primary transmission data 1 and the retransmission data 1 is realized.

At Slot5, primary transmission data 2 is transmitted on TB50, and retransmission data 2 is transmitted on TB51, so that simultaneous transmission of primary transmission data 2 and retransmission data 2 is realized.

At Slot6, since there is only retransmission data 3, retransmission data 3 is transmitted on TB52 along the original communication method.

Referring to fig. 4, fig. 4 is a schematic diagram of another embodiment of a communication method according to an embodiment of the present application. The communication method provided by the embodiment of the application comprises the following steps:

401. The network device determines to schedule the first data and the second data on the first time domain resource.

Step 401 is similar to step 301 described above and will not be described in detail herein.

After step 401, a scheme in which the first data and the second data are downlink data or uplink data is described. Wherein, steps 402-404 correspond to a processing scheme in which the first data and the second data are downlink data; steps 405-407 correspond to a processing scheme in which the first data and the second data are uplink data.

402. The network device generates fourth data based on the first data and the second data.

After step 401, in step 402, after the network device determines the primary data (first data) and the retransmission data (second data), the network device reassembles new data (or data packet) according to the primary data and the retransmission data, where the new data is referred to as fourth data in the embodiment of the present application. The network device transmits the fourth data at the same scheduling time.

The method comprises the following steps: the network equipment determines a radio link control service data unit (Radio link Control service Data Unit, RLC SDU) corresponding to the first data according to the first data; the network equipment determines the RLC SDU corresponding to the second data according to the second data; and the network equipment is used for recombining the RLC SDU corresponding to the first data and the RLC SDU corresponding to the second data to obtain fourth data, wherein the fourth data is a radio link control protocol data unit (Radio link Control Protocol Data Unit, RLC PDU).

The network device allocates related resources for the fourth data so that the fourth data can be transmitted at the same time as the medium access control (medium access control, MAC) layer. Since the fourth data has a larger data amount than the first data or the second data. Thus, the associated resources allocated by the network device for the fourth data are also larger than the associated resources allocated by the network device for the first data or the second data. For example: the bandwidth allocated for the fourth data is greater than the bandwidth allocated for the first data or the second data.

403. The network device sends third indication information to the terminal device, the third indication information indicates a third process to schedule fourth data, and time domain resources used by the third process are first time domain resources.

In step 403, the network device selects an idle process from idle (or available) HARQ processes of the terminal device as a third process. Wherein the third process is for scheduling fourth data. The time domain resource used by the third process is the first time domain resource. Specifically, the third indication information carries a sequence number of the third process, for example: HARQ sequence number of the third process. The third process includes indication information of the third transport block such that fourth data may be carried in the third transport block.

Then, the network device transmits third indication information to the terminal device. The third indication information is, for example, downlink control information (downlink control information, DCI).

404. The network device sends a third transport block to the terminal device, the third transport block carrying fourth data.

In step 404, the network device schedules a third transport block from the terminal device, where a scheduling time of the third transport block is the first time domain resource, and the third transport block carries the fourth data.

405. The network device sends third indication information to the terminal device, the third indication information indicates a third process to schedule fourth data, and time domain resources used by the third process are first time domain resources.

After step 401, in step 405, after the network device determines the primary data (first data) and the retransmission data (second data), the terminal device needs to reconstruct new data (or data packet) according to the primary data and the retransmission data, where the new data is referred to as fourth data in this embodiment of the present application. And the terminal equipment sends the fourth data to the network equipment at the same scheduling time.

Accordingly, the network device needs to allocate corresponding time domain resources (i.e., first time domain resources) for the fourth data and other resources (e.g., bandwidth, etc.) needed to transmit the fourth data. Specifically, the network device sends third indication information to the terminal device, where the third indication information indicates that the third process schedules fourth data, and the time domain resource used by the third process is the first time domain resource.

406. The terminal equipment generates fourth data according to the first data and the second data.

In step 406, the terminal device determines, according to the first data, a radio link control service data unit RLC SDU corresponding to the first data; the terminal equipment determines the RLC SDU corresponding to the second data according to the second data; and the terminal equipment is recombined to obtain fourth data according to the RLC SDU corresponding to the first data and the RLC SDU corresponding to the second data, wherein the fourth data is a radio link control protocol data unit (RLC PDU).

407. The terminal device sends a third transport block to the network device, the third transport block carrying fourth data.

In step 407, the terminal device determines a third process corresponding to the fourth data and the first time domain resource scheduled by the third process according to the third indication information. And the terminal equipment sends a third transmission block to the network equipment, wherein the scheduling time of the third transmission block is the first time domain resource, the third transmission block carries the fourth data, and the third transmission block is associated with the third process.

Fig. 7 is a schematic diagram of data transmission according to an embodiment of the present application, as shown in fig. 7. The network device is taken as an example to process the primary transmission data 1 and the retransmission data 1. When the network device determines that the data is Slot0, the primary transmission data 1 is stored in the memory, and the network device receives NACK feedback of TB01 corresponding to the retransmission data 1. Thus, in this TTI, there is a need for simultaneous transmission of primary data 1 and retransmission data 1. The network device selects 1 HARQ process from idle HARQ processes of the terminal device, and is used for scheduling primary transmission data 1 and retransmission data 1. And the network equipment reorganizes and generates reorganized data 1 according to the initial transmission data 1 and the retransmission data 1. The reorganized data 1 is sent on the TB00', so that the primary transmission data 1 and the retransmission data 1 are sent simultaneously.

At Slot5, the reorganized data 2 is generated according to the initial transmission data 2 and the retransmission data 2. The reorganized data 2 is then sent on TB 51'. The simultaneous transmission of the primary transmission data 2 and the retransmission data 2 is realized.
