Description
Technical Field

Background
A non-terrestrial communication network (non-terrestrial network, NTN) refers to a communication network between terminal devices and satellites (which may also be referred to as network devices).
In NTN systems, retransmissions may be performed by a hybrid automatic repeat request (hybrid automatic repeat request, HARQ) mechanism. In the HARQ mechanism, after receiving downlink data corresponding to one HARQ process sent by the network device, the terminal device decodes the downlink data, and sends HARQ feedback to the network device according to a decoding result. After the network device receives feedback of hybrid automatic repeat request acknowledgement (HARQ-ACK) sent by the terminal device, the network device sends other downlink data corresponding to the HARQ process to the terminal device. In the uplink process, if the network device schedules the terminal device to transmit uplink data through the HARQ process within a preset time period after the terminal device transmits the uplink data to the network device through the HARQ process, the terminal device ignores the scheduling of the HARQ process, that is, the terminal device does not transmit the uplink data through the HARQ process. However, due to the large transmission delay between the terminal device and the network device and the large number of interactions for data transmission via the HARQ mechanism, the efficiency of data transmission via the HARQ mechanism is low.

In order to better describe the principles and detailed implementation of the embodiments of the present application, the following describes the related technical content of the embodiments of the present application.
Downlink control information (downlink control information, DCI): for terminal devices with downlink traffic, the network device may schedule transmission of a physical downlink shared channel (physical downlink shared channel, PDSCH) for the terminal device through downlink grant DCI. The downlink grant DCI includes indication information of a physical uplink control channel (physical uplink control channel, PUCCH) resource, and after receiving the PDSCH, the terminal device may determine a decoding result (ACK or NACK information) of the PDSCH and feed back the decoding result to the network device through the PUCCH resource. In the NR system, DCI formats for PDSCH scheduling include DCI format 1_0, DCI format 1_1, and DCI format 1_2. Next, the information fields and bit sizes included in the DCI for each DCI format are described in conjunction with tables 1, 2 and 3, respectively.
TABLE 1
In table 1, a downlink allocation index, TPC commands of a predetermined PUCCH, PUCCH resource indication, PDSCH-to-HARQ feedback timing indication information field is used to feedback HARQ-ACK information corresponding to PDSCH transmission.
TABLE 2
In table 2, a downlink allocation index, TPC command of a predetermined PUCCH, PUCCH resource indication, PDSCH to HARQ feedback timing indication, single HARQ-ACK request, PDSCH group index, new feedback indication, requested PDSCH group number information field is used to feedback HARQ-ACK information corresponding to PDSCH transmission.
TABLE 3 Table 3
In table 3, a downlink allocation index, TPC commands of a predetermined PUCCH, PUCCH resource indication, PDSCH-to-harq_feedback timing indication information field is used to feedback HARQ-ACK information corresponding to PDSCH transmission.
In tables 2-3 above, for DCI format 1_1 and DCI format 1_2, the size of most information fields included in the DCI may be configured by the network device through higher layer parameters (e.g., radio resource control (radio resource control, RRC) signaling). For example, when the number of bits corresponding to the information field in the DCI format is 0, it indicates that the information field may not be included in the DCI format.
In the above tables 1 to 3, if the communication transmission between the network device and the terminal device occurs on the shared spectrum (for example, on the unlicensed spectrum), or the terminal device transmits the PUCCH through the resource on the unlicensed spectrum, the DCI may include a channel access indication (ChannelAccess-CPext) information field; if the communication transmission between the network device and the terminal device occurs on the licensed spectrum, the DCI does not include a channel access indication (channel access-CPext) information field.
For terminal devices with uplink traffic, the network device may schedule transmission of a physical uplink shared channel (physical uplink shared channel, PUSCH) for the terminal device through uplink grant DCI. The uplink grant DCI may include indication information for determining PUSCH resources, and the terminal device may transmit PUSCH on the determined PUSCH resources according to the uplink grant DCI. In an NR system, a DCI format for scheduling PUSCH transmission includes a DCI format 0_0, a DCI format 0_1, or a DCI format 0_2.
Hybrid automatic repeat request (hybrid automatic repeat request, HARQ) mechanism: the HARQ mechanism is a retransmission mechanism of a medium access control (medium access control, MAC) layer, through which data lost or transmitted in error can be retransmitted. The HARQ process comprises an uplink HARQ process and a downlink HARQ process, which are mutually independent.
In the related art (for example, in an NR system), HARQ retransmission is generally performed using stop-and-wait protocol (stop-and-wait protocol). When the equal stop protocol is adopted to perform HARQ retransmission, after the transmitting end transmits a Transport Block (TB) through one HARQ process, the transmitting end stops waiting for acknowledgement information (acknowledgement information is used to indicate whether the receiving end correctly receives the TB of the transport block), and in the waiting process, the transmitting end cannot transmit other TBs to the terminal device through the HARQ process. After the receiving end receives the TB corresponding to one HARQ process, the receiving end decodes the TB, if the decoding is successful, the receiving end sends Acknowledgement (ACK) to the transmitting end, and if the decoding is failed, the receiving end sends negative acknowledgement (negative acknowledgement, NACK) to the transmitting end. If the sending end receives the ACK information corresponding to the HARQ process, the sending end can send other TB to the receiving end through the HARQ process. If the sender receives NACK corresponding to the HARQ process or the sender does not receive any response for a long time, the sender can retransmit the TB through the HARQ process. In the above process, when the transmitting end is a network device, the receiving end may be a terminal device. When the transmitting end is a terminal device, the receiving end may be a network device or another terminal device.
In the related art, the network device may indicate the maximum number of HARQ processes for uplink and downlink to the terminal device by means of, for example, radio resource control (Radio Resource Control, RRC) signaling semi-static configuration. If the network device does not provide the corresponding configuration parameters, the number of downlink HARQ processes may be a default value, e.g. 8. The maximum number of HARQ processes supported per carrier uplink may be 16. Wherein each HARQ process corresponds to a HARQ process number (HARQ process number, HPN), also called HARQ ID (Identity).
Fig. 1 illustrates how the number of HARQ processes and Round Trip Time (RTT) affect the throughput of data transmission, taking downlink transmission as an example. As shown in fig. 1, the maximum number of HARQ processes configured by the terminal device is 16, and 16 HARQ processes including HARQ0 to HARQ15 may be continuously scheduled within 16 ms. For one HARQ process, for example, HARQ0, after it is scheduled, the HARQ process HARQ0 is in a stop state during a data round trip and cannot be used for transmitting other data, so in the scenario of the maximum HARQ process number of 16 of the terminal device shown in fig. 1, there may be the following cases:
If the RTT is less than 16ms, in the RTT range after HARQ0 is scheduled, when there is traffic data to be transmitted, the terminal device may always have parallel HARQ processes (one or more of HARQ1 to HARQ 15) for data transmission; when the time after HARQ0 is scheduled exceeds RTT, HARQ0 may be used again for transmitting data. Therefore, data can be continuously transmitted on the HARQ entity constituted by HARQ0 to HARQ15 without affecting the maximum throughput of the terminal device. In addition, if RTT is equal to 16ms and the maximum number of HARQ processes configured by the terminal device is 16, it is known that, in the same way, there is always a HARQ process capable of transmitting service data; however, if the maximum number of HARQ processes configured by the terminal device is less than 16, when there is traffic data to be transmitted, it is possible that all HARQ processes are in a state of waiting for feedback from the network device, and at this time, no HARQ process is available, which affects the throughput of data transmission by the terminal device.
If the RTT is much larger than 16ms, for example, the RTT in NTN systems can reach 600ms, which may be the case in practice: all HARQ processes of the terminal equipment are in a state of not receiving feedback of the network equipment, and when the terminal equipment has service data to be transmitted, the HARQ processes are not available for a long time, so that the throughput of data transmission of the terminal equipment is seriously affected.
That is, in an application scenario of the NTN system or other similar scenarios, due to the great increase of RTT, the number of HARQ processes configured by the terminal device is not matched with the system RTT, which ultimately results in a decrease in system performance.
In order to solve the above technical problems, an embodiment of the present application proposes a method for determining a state of an HARQ process, and in order to facilitate understanding of the method for determining a state of an HARQ process shown in the present application, first, an architecture of a communication system in the present application is described with reference to fig. 2A to fig. 2B.
Fig. 2A is a schematic architecture diagram of a communication system according to an embodiment of the present application. Referring to fig. 2A, the terminal device 201 and the satellite 202 are included, and wireless communication is possible between the terminal device 201 and the satellite 202. The network formed between the terminal device 201 and the satellite 202 may also be referred to as NTN. In the architecture of the communication system shown in fig. 2A, the satellite 202 has a function of a base station, and direct communication is possible between the terminal device 201 and the satellite 202. Under the system architecture, satellite 202 may be referred to as a network device.
Fig. 2B is a schematic diagram of another architecture of a communication system according to an embodiment of the present application. Referring to fig. 2B, the base station 303 includes a terminal device 301, a satellite 302, and a base station 303, where wireless communication is possible between the terminal device 301 and the satellite 302, and communication is possible between the satellite 302 and the base station 303. The network formed between terminal equipment 301, satellites 302 and base stations 303 may also be referred to as NTN. In the architecture of the communication system shown in fig. 2B, the satellite 302 does not have the function of a base station, and communication between the terminal device 301 and the base station 303 requires intermediation through the satellite 302. Under such a system architecture, the base station 303 may be referred to as a network device.
It should be noted that fig. 2A-2B are only exemplary systems to which the present application is applicable, and of course, the method shown in the embodiment of the present application may also be applicable to other systems, for example, a 5G communication system, an LTE communication system, etc., which is not limited in particular. Embodiments of the present application may include at least some of the following.
In the present application, in a scenario where RTT is large (for example, NTN), in order to improve data transmission efficiency between a terminal device and a network device, for a downlink HARQ process of the terminal device, the network device may configure or indicate, to the terminal device, a HARQ feedback function state corresponding to the downlink HARQ process. For example, the HARQ feedback function state corresponding to the downlink HARQ process is configured to be a non-enabled state. Correspondingly, if the terminal equipment determines that the HARQ feedback function state corresponding to the downlink HARQ process is in a non-enabled state, the terminal equipment is subjected to downlink grant scheduling, after receiving data on the downlink HARQ process, and does not feed back HARQ-ACK information to the HARQ process according to the downlink grant. The network equipment can continue to schedule other data to the terminal equipment through the HARQ process without waiting for HARQ-ACK information feedback corresponding to the HARQ process, so that the network equipment does not need to wait, and the data transmission efficiency between the terminal equipment and the network equipment is improved.
Or, for the uplink HARQ process of the terminal device, the network device may configure or indicate, to the terminal device, the HARQ feedback function state corresponding to the uplink HARQ process. For example, the HARQ feedback function state corresponding to the uplink HARQ process is configured to be a non-enabled state. Correspondingly, if the terminal equipment determines that the HARQ feedback function state corresponding to the uplink HARQ process is in a non-enabled state, after the terminal equipment is scheduled by the uplink grant to send a TB on the uplink HARQ process, the terminal equipment can transmit another TB again by using the uplink HARQ process according to the indication of the network equipment without waiting for the feedback of the network equipment for the TB, so that the data transmission efficiency between the terminal equipment and the network equipment is improved.
In the present application, the state of the HARQ feedback function corresponding to the downlink HARQ process or the uplink HARQ process of the terminal device may be a non-enabled state. For example, the network device may configure the HARQ feedback function state corresponding to part or all of the HARQ processes of the terminal device to an enabled state or a disabled state. Wherein the disabled state is also referred to as disabled state (disabled).
Optionally, for a downlink HARQ process, if the HARQ feedback function state corresponding to one HARQ process is an enabled state, after receiving a transport block TB through the HARQ process, the terminal device needs to send HARQ-ACK information corresponding to the TB to the network device; or the terminal equipment needs to receive the feedback of the network equipment to the TB so as to reuse the HARQ process; or, the terminal equipment needs to feed back corresponding HARQ-ACK information according to the DCI for dispatching the TB; or the terminal equipment sends the HARQ-ACK information corresponding to the first physical channel transmitted in the HARQ process to the network equipment according to the DCI of the first physical channel transmitted through the HARQ process.
Optionally, for a downlink HARQ process, if the HARQ feedback function state corresponding to one HARQ process is a non-enabled state, after the terminal device receives the TB through the HARQ process, it is not necessary to send HARQ-ACK information corresponding to the TB to the network device; or the terminal equipment can reuse the HARQ process without receiving the feedback of the network equipment to the TB; or, the terminal equipment does not need to feed back corresponding HARQ-ACK information according to the DCI for dispatching the TB; or the terminal equipment does not transmit the DCI of the first physical channel through the HARQ process according to the dispatching, and transmits the HARQ-ACK information corresponding to the first physical channel transmitted in the HARQ process to the network equipment.
Optionally, in the present application, the HARQ-ACK information includes ACK information or NACK information corresponding to a decoding result of the TB.
Optionally, for an uplink HARQ process, if the HARQ feedback function state corresponding to one HARQ process is an enabled state, after the terminal device sends a transport block TB through the HARQ process, the terminal device needs to receive feedback from the network device on the TB to reuse the HARQ process (e.g. send a new TB using the HARQ process or send the TB again); or, the terminal device waits for the feedback of the network device to the first physical channel transmitted in the HARQ process.
Optionally, for an uplink HARQ process, if the HARQ feedback function state corresponding to one HARQ process is a non-enabled state, it is indicated that after the terminal device sends a TB through the HARQ process, the HARQ process may be reused without receiving feedback from the network device on the TB (e.g., using the HARQ process to send a new TB or resending the TB); or, the terminal device does not wait for the feedback of the network device to the first physical channel transmitted in the HARQ process.
Optionally, the time interval between two uses of the same HARQ process is greater than or equal to the first time length, and/or the time interval between two uses of the same HARQ process may be less than the second time length. Wherein the first time length is determined according to the decoding time of the receiving device, and the second time length is determined according to RTT. Wherein the first time length is less than the second time length.
Optionally, for downlink transmission, the feedback includes the terminal device sending HARQ-ACK information to the network device.
Optionally, for uplink transmission, the feedback includes the network device sending HARQ-ACK information to the terminal device, or the network device sending uplink grant DCI to the terminal device.
Optionally, for the downlink procedure:
When the HARQ process feedback function status of the HARQ process is disabled, the terminal device does not feed back the HARQ process (which may also be understood as that the terminal device does not respond to the HARQ process). That is, after the network device sends the TB to the terminal device through the HARQ process, the terminal device does not need to send a feedback message (ACK, NACK or CSI) corresponding to the HARQ process to the network device, and the network device does not need to wait for the feedback message of the terminal device, and can send the TB again through the HARQ process, for example, transmit a new TB through the HARQ process. It should be noted that the above-mentioned disabled state may also be referred to as a disabled state.
Next, a description will be given of a non-enabled HARQ process with reference to fig. 3.
Fig. 3 is a schematic diagram of processing a non-enabled HARQ process according to an embodiment of the present application. Referring to fig. 3, it is assumed that a plurality of HARQ processes are included in the terminal device, and HARQ process 7 of the plurality of HARQ processes is a non-enabled HARQ process. The network device sends downlink data corresponding to PDSCH 0 to the terminal device through HARQ process 7, and NDI is 0. Since the HARQ process 7 is a non-enabled HARQ process, after receiving the downlink data corresponding to the HARQ process 7, the terminal device does not need to send a feedback message of the HARQ process 7 to the network device, and the network device does not need to wait for the feedback message of the HARQ process 7 sent by the terminal device, so that other data can be sent to the terminal device through the HARQ process 7. For example, the network device may send downlink data corresponding to PSDCH 1 to the terminal device through HARQ process 7, and flip NDI to 1, where the flip of NDI indicates that the downlink data transmitted through HARQ process 7 is a new downlink data packet. After the network device sends the downlink data corresponding to the PDSCH 1 to the terminal device, the network device may continue to send a new downlink data packet corresponding to the PDSCH 2 to the terminal device, and flip the NDI to 0.
When the HARQ process feedback function status of the HARQ process is enabled, the terminal device feeds back the HARQ process (which may also be understood as that the terminal device responds to the HARQ process). That is, after the network device sends a TB to the terminal device through the HARQ process, the terminal device needs to send an HARQ feedback message (ACK, NACK, or CSI) to the network device, and after the network device receives the feedback message, the network device may send the TB through the HARQ process, if the TB is retransmitted through the HARQ process, the TB is a retransmitted TB, and if the TB is new TB through the HARQ process, the TB is new.
Optionally, for the uplink procedure:
when the HARQ feedback function state of the HARQ process is in a non-enabled state, the terminal equipment does not wait for the feedback of the network equipment to the first physical channel transmitted in the HARQ process. The feedback by the network device to the first physical channel in the first HARQ process comprises at least one of: the network equipment sends HARQ-ACK information corresponding to a first physical channel; the network device sends an uplink grant that schedules the first HARQ process for transmission. In this case, within a preset period after the terminal device sends uplink data to the network device through the HARQ process, if the network device schedules the terminal device to perform uplink data transmission again through the HARQ process, the terminal device may perform uplink data transmission through the HARQ process.
When the HARQ feedback function state of the HARQ process is in an enabling state, the terminal equipment waits for the feedback of the network equipment to the first physical channel transmitted in the HARQ process. In this case, within a preset time period after the terminal device sends uplink data to the network device through the HARQ process, if the network device schedules the terminal device to perform uplink data transmission through the HARQ process again, the terminal device ignores scheduling of the HARQ process. Or, the terminal device does not expect the network device to schedule the HARQ process again within the preset time period.
In the present application, the network device may configure some or all HARQ processes in the terminal device to a non-enabled state, or the network device may also indicate the HARQ feedback function state of the HARQ processes in the terminal device through DCI. Correspondingly, the terminal device can determine the HARQ feedback function state of the HARQ process according to the indication information sent by the network device. In the downlink process, when the HARQ process is in a non-enabled state, the terminal equipment does not need to feed back the HARQ process to the network equipment, and the network equipment can continuously transmit other data to the terminal equipment through the HARQ process, so that the network equipment does not need to wait, and the data transmission efficiency between the terminal equipment and the network equipment is improved. In the uplink process, when the HARQ process is in a non-enabled state, after the terminal equipment transmits uplink data through the HARQ process, the terminal equipment can transmit the uplink data through the HARQ process without waiting for a preset time length, so that the data transmission efficiency between the terminal equipment and the network equipment is improved.
The technical scheme shown in the application is described in detail by specific examples. It should be noted that the following embodiments may exist independently or may be combined with each other, and for the same or similar content, the description will not be repeated in different embodiments.
Fig. 4 is a flowchart of a method for determining a state of an HARQ process according to an embodiment of the present application. Referring to fig. 4, the method may include:
s401, the network equipment generates indication information.
Optionally, before the network device receives the downlink physical channel or sends the uplink physical channel through the first HARQ process scheduling terminal device, the network device may generate indication information corresponding to the first HARQ process, where the indication information is used to determine an HARQ feedback function state of the first HARQ process, where the HARQ feedback function state includes a non-enabled state or an enabled state.
The indication information may include at least one of the following information: the first indication information, the second indication information and the third indication information.
Optionally, the first indication information is used to configure a HARQ feedback function state of the first HARQ process. For example, the first indication information may be used to configure the HARQ feedback function state of the first HARQ process to an enabled state or a disabled state.
Optionally, the second indication information is used to activate or deactivate a non-enabled state of the first HARQ process. The first HARQ process may be configured to be in a disabled state, for example, by the first indication information, or the terminal device may predefine the first HARQ process to be in a disabled state, or the second indication information indicates that the first HARQ process is in a disabled state. Optionally, for downlink, after the non-enabled state of the first HARQ process is activated, the terminal device does not feed back the first HARQ process; and when the non-enabled state of the first HARQ process is not activated, the terminal equipment feeds back the first HARQ process. Optionally, for uplink, after the non-enabled state of the first HARQ process is activated, the terminal device does not wait for the feedback of the network device to the first physical channel transmitted in the first HARQ process; after the enabled state of the first HARQ process is activated, the terminal device waits for the feedback of the network device to the first physical channel transmitted in the first HARQ process. Alternatively, the second indication information may be DCI or a medium access control (medium access control, MAC) Control Element (CE) or RRC signaling.
Optionally, the third indication information is used to dynamically indicate the HARQ feedback function status of the first HARQ process of the terminal device. For example, assuming that the first HARQ process is a downlink process, if the downlink grant DCI received by the terminal device for scheduling the first HARQ process to transmit the first physical channel includes third indication information, where the third indication information is used to indicate that the first HARQ process is in a non-enabled state, the terminal device determines that HARQ-ACK feedback is not performed on the first physical channel transmitted in the first HARQ process according to the downlink grant DCI; or if the downlink grant DCI received by the terminal device for scheduling the first HARQ process to transmit the first physical channel includes third indication information, where the third indication information is used to indicate that the first HARQ process is in an enabled state, the terminal device determines to perform HARQ-ACK feedback on the first physical channel transmitted in the first HARQ process according to the downlink grant DCI. Alternatively, the third indication information may be DCI or information included in DCI.
S402, the network equipment sends indication information to the terminal equipment.
Optionally, if the indication information includes two or three of the first indication information, the second indication information, and the third indication information, the order in which the network device sends the indication information to the terminal device is sequentially: the first indication information, the second indication information and the third indication information.
For example, if the indication information includes the first indication information and the second indication information, the network device sends the first indication information to the terminal device and then sends the second indication information to the terminal device.
Of course, the application is not limited in this regard. For example, the network device may also send at least two of the first indication information, the second indication information, and the third indication information to the terminal device through the same time unit. Or, the network device may also send at least two of the first indication information, the second indication information and the third indication information to the terminal device at the same time.
S403, the terminal equipment determines the HARQ feedback function state of the first HARQ process according to the indication information.
When the first HARQ process is a downlink HARQ process:
optionally, if the HARQ feedback function state of the first HARQ process is a non-enabled state, the terminal device does not send HARQ-ACK information corresponding to the first physical channel transmitted in the first HARQ process to the network device, and correspondingly, the network device does not receive HARQ-ACK information corresponding to the first physical channel transmitted in the first HARQ process.
Optionally, if the HARQ feedback function state of the first HARQ process is an enabled state, the terminal device sends HARQ-ACK information corresponding to the first physical channel transmitted in the first HARQ process to the network device, and correspondingly, the network device receives HARQ-ACK information corresponding to the first physical channel transmitted in the first HARQ process.
Optionally, when the first HARQ process is a downlink HARQ process, and when it is determined that the HARQ feedback function state of the first HARQ process is a non-enabled state, the terminal device does not send HARQ-ACK information of a first physical channel to the network device, where the first physical channel includes at least one of the following cases:
the first physical channel is a physical downlink shared channel PDSCH scheduled by a first DCI, the first DCI is a downlink grant, and the first physical channel is transmitted through a first HARQ process.
The first physical channel is a semi-persistent scheduling (SPS) PDSCH scheduled by a second DCI, which is SPS configuration activation signaling, the first physical channel being transmitted by the first HARQ process.
The first physical channel is SPS PDSCH without DCI scheduling, and is transmitted through the first HARQ process.
The first physical channel is a PDCCH for indicating SPS PDSCH release, and corresponds to the first HARQ process.
When the first HARQ process is an uplink HARQ process:
optionally, if the HARQ feedback function status of the first HARQ process is in a disabled state, the terminal device does not wait for feedback of the network device to the first physical channel transmitted in the first HARQ process, and accordingly, after the network device transmits the first physical channel using the first HARQ process by using the first time domain resource, the network device may also transmit the second physical channel using the first HARQ process by using the second time domain resource. Wherein the interval between the first time domain resource and the second time domain resource is less than the first time length. The first time length may be determined according to RTT, or the first time length is RTT length, or the first time length is a preset value.
Optionally, if the HARQ feedback function status of the first HARQ process is an enabled status, the terminal device waits for feedback of the network device to the first physical channel transmitted in the first HARQ process. Accordingly, the network device cannot transmit the second physical channel using the first HARQ process at the second time domain resource after the first physical channel is transmitted using the first HARQ process at the first time domain resource. Wherein the interval between the first time domain resource and the second time domain resource is less than the first time length. The first time length may be determined according to RTT, or the first time length is RTT length, or the first time length is a preset value.
According to the HARQ feedback function state determining method for the HARQ process, provided by the embodiment of the application, the network equipment can indicate the HARQ feedback function state of the first HARQ process through the indication information. The terminal device may determine, according to the indication information, a HARQ feedback function state of the first HARQ process. In the downlink process, when the first HARQ process is in a non-enabled state, the terminal equipment does not need to feed back the first HARQ process to the network equipment, and the network equipment can continuously transmit other data to the terminal equipment through the first HARQ process, so that the network equipment does not need to wait, and the data transmission efficiency between the terminal equipment and the network equipment is improved. In the uplink process, when the first HARQ process is in a non-enabled state, after the terminal equipment transmits uplink data through the first HARQ process, the terminal equipment can transmit the uplink data through the first HARQ process without waiting for a preset time length, so that the data transmission efficiency between the terminal equipment and the network equipment is improved.
The indication information may include one or more of the first indication information, the second indication information, and the third indication information. When the indication information is different, the method for determining the HARQ feedback function state of the HARQ process by the terminal equipment is also different. Next, a method for determining the HARQ feedback function status of the HARQ process when the indication information is different will be described.
Fig. 5 is a flowchart of another method for determining a state of an HARQ process according to an embodiment of the present application. In the embodiment shown in fig. 5, the indication information includes first indication information. Referring to fig. 5, the method may include:
s501, the network equipment generates first indication information.
The first indication information is used for configuring HARQ processes which are not fed back by the terminal equipment and/or HARQ processes which are fed back. Or, the first indication information is used for configuring the HARQ feedback function state of the HARQ process of the terminal device.
Optionally, the first indication information is RRC signaling.
Optionally, the first indication information includes at least one of the following information:
information 1, first configuration information, where the first configuration information is used to configure a set of HARQ processes in the terminal device.
Information 2, second configuration information, where the second configuration information is used to configure the HARQ feedback function status of the HARQ process of the terminal device.
Information 3, third configuration information, where the third configuration information is used to configure the HARQ feedback function state of the HARQ process set of the terminal device.
Information 4, identification of the first HARQ process.
Information 5, identification of the HARQ process set where the first HARQ process is located.
Information 6, first parameter information, where the first parameter information is used to indicate a feedback function status of at least one HARQ process, and the at least one HARQ process includes a first HARQ process.
Information 7, first time information, where the first time information is used to indicate a configuration effective time of at least one HARQ process, and the at least one HARQ process includes a first HARQ process.
For information 1 in the first indication information, the first configuration information may configure HARQ processes in the terminal device as one or more sets of HARQ processes.
Optionally, the first configuration information may include one or more of the following information: the number of HARQ processes in the set of HARQ processes, the identity of the HARQ processes comprised in the set of HARQ processes, the number of HARQ processes comprised in the set of HARQ processes.
For example, assuming that 16 HARQ processes are included in the terminal device, the number of HARQ process sets included in the first configuration information is 2, 8 HARQ processes are included in the HARQ process set 1, and 8 HARQ processes are included in the HARQ process set 2. The two HARQ process sets configured according to the first configuration information may be: HARQ process set 1 includes HARQ process 1-HARQ process 8, and HARQ process set 2 includes HARQ process 9-HARQ process 16.
For example, assuming that 16 HARQ processes are included in the terminal device, the number of HARQ process sets included in the first configuration information is 2, and HARQ process 1-HARQ process 5 are included in HARQ process set 1. The two HARQ process sets configured according to the first configuration information may be: HARQ process set 1 includes HARQ process 1-HARQ process 5, and HARQ process set 2 includes HARQ process 6-HARQ process 16.
For information 2 in the first indication information, the second configuration information may be used to configure the HARQ process in the non-enabled state, and/or the second configuration information may be used to configure the HARQ process in the enabled state.
Optionally, if the second configuration information is used for configuring the non-enabled HARQ process, the second configuration information may include an identifier of the non-enabled HARQ process. Accordingly, HARQ processes except for the enabled HARQ process in the terminal device are enabled HARQ processes.
For example, assuming that the terminal device includes 16 HARQ processes, the second configuration information is used for configuring the HARQ processes in the disabled state, and the second configuration information includes the identifiers of the HARQ processes 1 to 5, the HARQ processes 1 to 5 in the terminal device are the HARQ processes in the disabled state, and the HARQ processes 6 to 16 in the terminal device are the HARQ processes in the disabled state.
Optionally, if the second configuration information is used for configuring the enabled HARQ process, the second configuration information may include an identifier of the enabled HARQ process. Accordingly, the HARQ processes except the enabled HARQ process in the terminal device are all non-enabled HARQ processes.
For example, assuming that the terminal device includes 16 HARQ processes, the second configuration information is used for configuring the enabled HARQ process, and the second configuration information includes the identifiers of HARQ process 1-HARQ process 8, HARQ process 1-HARQ process 8 in the terminal device is the enabled HARQ process, and HARQ process 9-HARQ process 16 in the terminal device is the disabled HARQ process.
Optionally, if the second configuration information is used for configuring the non-enabled HARQ process and configuring the enabled HARQ process, the second configuration information may include an identifier of the non-enabled HARQ process and an identifier of the enabled HARQ process.
For example, assuming that the terminal device includes 16 HARQ processes, the second configuration information is used to configure the non-enabled HARQ process and configure the enabled HARQ process, where the second configuration information may indicate that HARQ process 1-HARQ process 8 in the terminal device is the non-enabled HARQ process and HARQ process 9-HARQ process 16 in the terminal device is the enabled HARQ process.
Alternatively, if the first indication information includes information 2, the terminal device may determine the HARQ feedback function status of the first HARQ process according to information 2, where the first indication information may not include information 4, information 5, or information 7.
For example, the second configuration information may be as shown in table 4:
TABLE 4 Table 4
Referring to table 4, assuming that the terminal device includes 8 HARQ processes, the process numbers of the 8 HARQ processes are sequentially 0 to 7, as can be seen from the second configuration information shown in table 4, the non-enabled HARQ process includes: HARQ process 0, HARQ process 1, HARQ process 4 and HARQ process 5. The enabled HARQ process includes: HARQ process 2, HARQ process 3, HARQ process 6 and HARQ process 7.
For information 3 in the first indication information, the third configuration information may be used to configure the set of HARQ processes in the non-enabled state, and/or the second configuration information may be used to configure the set of HARQ processes in the enabled state.
Optionally, the HARQ processes in the set of non-enabled HARQ processes are all in a non-enabled state, and the HARQ processes in the set of enabled HARQ processes are all in an enabled state.
Optionally, if the third configuration information is used for configuring the non-enabled HARQ process set, the third configuration information may include an identifier of the non-enabled HARQ process set. Accordingly, HARQ processes except the set of enabled HARQ processes in the terminal device are enabled HARQ processes.
For example, assuming that the terminal device includes two process sets, which are respectively denoted as HARQ process set 1 and HARQ process set 2, the third configuration information is used for configuring the non-enabled HARQ process set, and the third configuration information includes the identifier of the HARQ process set 1, the HARQ process in the HARQ process set 1 in the terminal device is the non-enabled HARQ process, and the HARQ process in the HARQ process set 2 in the terminal device is the enabled HARQ process.
Optionally, if the third configuration information is used for configuring the enabled HARQ process set, the third configuration information may include an identifier of the enabled HARQ process set. Accordingly, the HARQ processes except the enabled HARQ process set in the terminal device are all non-enabled HARQ processes.
For example, assuming that the terminal device includes two process sets, which are respectively denoted as HARQ process set 1 and HARQ process set 2, the third configuration information is used for configuring the enabled HARQ process set, and the third configuration information includes the identifier of the HARQ process set 1, the HARQ process in the HARQ process set 1 in the terminal device is the enabled HARQ process, and the HARQ process in the HARQ process set 2 in the terminal device is the disabled HARQ process.
Optionally, if the third configuration information is used for configuring the non-enabled HARQ process and configuring the enabled HARQ process, the third configuration information may include an identifier of the non-enabled HARQ process and an identifier of the enabled HARQ process.
For example, assuming that the terminal device includes two process sets, which are respectively denoted as HARQ process set 1 and HARQ process set 2, the second configuration information is used to configure the non-enabled HARQ process set and configure the enabled HARQ process set, and the second configuration information may indicate that the HARQ process in the HARQ process set 1 in the terminal device is an enabled HARQ process, and/or indicate that the HARQ process in the HARQ process set 2 in the terminal device is a non-enabled HARQ process.
Alternatively, if the first indication information includes information 3, the terminal device may determine the HARQ feedback function status of the first HARQ according to information 3, in which case the first indication information may not include information 4, information 5, or information 7.
For example, the third configuration information may be as shown in table 5:
TABLE 5
Referring to table 5, the terminal device includes two HARQ process sets, namely, HARQ process set 0 and HARQ process set 1, where HARQ process set 0 includes HARQ process 0 to HARQ process 3, and HARQ process set 1 includes HARQ process 4 to HARQ process 7. As can be seen from the third configuration information shown in table 5, the HARQ process in the HARQ process set 0 is in the inactive state, and the HARQ process in the HARQ process set 1 is in the active state.
Alternatively, for information 4 in the first indication information, the identification of the first HARQ process may be a sequence number of the first HARQ process. For example, assuming that 16 HARQ processes are included in the terminal device, the identity of the first HARQ process may be any integer between 1 and 16.
Optionally, for information 5 in the first indication information, the identifier of the HARQ process set where the first HARQ process is located may be a sequence number of the HARQ process set. For example, assuming that two HARQ process sets are included in the terminal device, the identity of the HARQ process set in which the first HARQ process is located may be HARQ process set 1 or HARQ process set 2.
Optionally, for information 6 in the first indication information, optionally, when the value of the first parameter is a first preset value, for example, 1, the first parameter information is used to determine that the first HARQ process is in a non-enabled state; or when the value of the first parameter is a second preset value, for example, 0, the first parameter information is used for determining that the first HARQ process is in an enabled state. Optionally, if the first parameter is configured, it may be determined that the first HARQ process is in a non-enabled state; or, if the first parameter is not configured, the first HARQ process may be determined to be enabled.
Optionally, the first parameter includes an uplink HARQ feedback disable parameter for determining whether uplink feedback of the downlink HARQ process is disabled. For example, if the terminal device is configured with the first parameter, at least one HARQ process of the terminal device may be a non-enabled state, e.g. an uplink HARQ feedback de-enabled HARQ process; or, if the terminal device receives the first parameter and the first parameter is a preset value, for example TRUE, at least one HARQ process of the terminal device may be a non-enabled HARQ process.
For the information 7 in the first indication information, the content included in the first time information may include three cases as follows:
the case 1, the first time information includes a period, where the period may be a configuration effective time of the HARQ process in the terminal device. The period may include a start time and an end time, for example, the period included in the first time information may be 2019 1 month 1 st to 2019 1 month 3 st, and the configuration of the HARQ process in the terminal device by the first indication information is validated in 2019 1 month 1 st to 2019 1 month 3 st, and at other times, the configuration of the HARQ process in the terminal device by the first indication information is not validated.
The case 2, the first time information includes a starting time and/or a duration, where the starting time is a starting time when the configuration of the HARQ process in the terminal device takes effect. The time length is the time length for which the HARQ process configuration in the terminal equipment takes effect. If the first time information does not include the starting time, the time when the terminal device receives the first indication information may be determined as the starting time.
The case 3, the first time information may include a start time and an end time, where the start time is a start effective time of HARQ process configuration in the terminal device, and the end time is an end effective time of HARQ process configuration in the terminal device.
In any of the above three cases, the first time information may further include an effective period.
S502, the network equipment sends first indication information to the terminal equipment.
S503, the terminal equipment determines the HARQ feedback function state of the first HARQ process according to the first indication information.
When the first HARQ process is a downlink HARQ process, if the first HARQ process is in a non-enabled state, the terminal equipment determines that feedback is not carried out on the first HARQ process. If the first HARQ process is in an enabling state, the terminal equipment determines to feed back the first HARQ process.
When the first HARQ process is an uplink HARQ process, if the HARQ feedback function state of the first HARQ process is a non-enabled state, the terminal equipment does not wait for the feedback of the network equipment to the first physical channel transmitted in the first HARQ process; or if the HARQ feedback function state of the first HARQ process is an enabled state, the terminal device waits for the feedback of the network device to the first physical channel transmitted in the first HARQ process.
In the embodiment shown in fig. 5, in the downlink process, the network device may indicate to the terminal device whether to feed back the first HARQ process through the first indication information; when the terminal equipment determines that the first HARQ process is not fed back according to the first indication information, the terminal equipment does not need to feed back the HARQ process, and the network equipment can transmit other data through the HARQ process without waiting for the feedback of the terminal equipment, so that the data transmission efficiency is improved. In the uplink process, the network device can indicate whether to wait for the feedback of the network device to the first physical channel transmitted in the first HARQ process or not to the terminal device through the first indication information; when the terminal equipment determines not to wait for the feedback of the network equipment to the first physical channel transmitted in the first HARQ process according to the first indication information, after the terminal equipment transmits uplink data through the first HARQ process, the terminal equipment can transmit the uplink data through the first HARQ process without waiting for a preset time length, and the data transmission efficiency between the terminal equipment and the network equipment is improved.
The method shown in the embodiment of fig. 5 will be described below by way of specific examples.
Example 1, assuming that 8 HARQ processes are included in the terminal device, the network device transmits RRC signaling (first indication information) to the terminal device including the second configuration information shown in table 4. If the 8 HARQ processes are downlink HARQ processes, after receiving the RRC signaling, the terminal device determines that the HARQ processes that do not perform feedback include: HARQ process 0, HARQ process 1, HARQ process 4, and HARQ process 5, where the HARQ process fed back by the terminal device includes: HARQ process 2, HARQ process 3, HARQ process 6 and HARQ process 7. For example, after the terminal device receives the downlink data corresponding to the HARQ process 0, the terminal device does not feed back the HARQ process 0. After the terminal equipment receives the downlink data corresponding to the HARQ process 2, the terminal equipment does not feed back the HARQ process 2. If the 8 HARQ processes are uplink HARQ processes, after receiving the RRC signaling, the terminal device determines that the HARQ process that does not wait for feedback includes: HARQ process 0, HARQ process 1, HARQ process 4, and HARQ process 5, where the HARQ process for which the terminal device waits for feedback includes: HARQ process 2, HARQ process 3, HARQ process 6 and HARQ process 7. For example, after the terminal device sends the uplink data through the HARQ process 0, the terminal device may perform uplink data transmission through the HARQ process 0 without waiting for the network device to feed back the physical channel transmitted in the HARQ process 0.
Example 2, assuming that 8 HARQ processes are included in the terminal device, the network device sends RRC signaling (first indication information) to the terminal device, including third configuration information shown in table 5, and assuming that RRC signaling further includes first time information, including period 1. If the 8 HARQ processes are downlink HARQ processes, after the terminal device receives the RRC signaling, in period 1, the terminal device does not perform feedback on the HARQ processes in the HARQ process set 0, and the terminal device performs feedback on the HARQ processes in the HARQ process set 1. And in other time periods, the terminal equipment feeds back all HARQ processes. If the 8 HARQ processes are uplink HARQ processes, after the terminal device receives the RRC signaling, in period 1, the terminal device does not wait for the network device to feed back to the HARQ process in the HARQ process set 0, and the terminal device waits for the network device to feed back to the HARQ process in the HARQ process set 1. In other periods, the terminal device waits for feedback from the network device for all HARQ processes.
Fig. 6 is a flowchart of another method for determining a state of an HARQ process according to an embodiment of the present application. In the embodiment shown in fig. 6, the indication information includes second indication information. Referring to fig. 6, the method may include:
S601, the network equipment generates second indication information.
The second indication information is used to activate or deactivate a non-enabled state of the first HARQ process, which is the non-enabled state. The first HARQ process being inactive may be indicated in the second indication information, or the network device is preconfigured to the terminal device, or the terminal device is preconfigured, or a protocol is agreed, etc.
Optionally, the second indication information is DCI or MAC CE or RRC. Alternatively, the DCI may be DCI of CS-RNTI scrambling code.
The second indication information includes at least one of the following information: the method comprises the steps of identifying a first HARQ process, identifying a HARQ process set where the first HARQ process is located, second parameter information and second time information. The second parameter information is used for indicating to activate or deactivate the HARQ feedback function state of at least one HARQ process, and the at least one HARQ process comprises a first HARQ process; the second time information is used to indicate an activation effective time of at least one HARQ process, including the first HARQ process.
Alternatively, the content included in the second time information may include three cases as follows:
the case 1, the second time information includes a period, and the period may be an active time of activation of a non-enabled state of the first HARQ process. The period of time may include a start time and an end time. During this period, the non-enabled state of the first HARQ process is activated, and during other periods, the non-enabled state of the first HARQ process is not activated.
The case 2, the second time information includes a start time and/or a duration, where the start time is a start time of activating a non-enabled state of the first HARQ process. The duration is a duration in which the non-enabled state of the first HARQ process is activated. If the second time information does not include the starting time, the time when the terminal device receives the second instruction information may be determined as the starting time.
The case 3 and the second time information may include a start time and an end time, where the start time is a time when the non-enabled state of the first HARQ process is activated, and the end time is a time when the non-enabled state of the first HARQ process is deactivated.
In any of the above three cases, the second time information may further include an effective period.
Alternatively, the second parameter information may include at least one of the following two cases:
in case 1, the second parameter information is information in the first information domain in the second instruction information.
If the information in the first information field is first preset information, the first HARQ process is an activated non-enabled HARQ process; or if the information in the first information field is the second preset information, the first HARQ process is a deactivated non-enabled HARQ process. For example, when the second indication information is DCI, the first information field is a redundancy version information field in the DCI.
The first HARQ process being an active non-enabled HARQ process means that the first HARQ process that has been configured to be non-enabled is activated.
The first HARQ process being a deactivated non-enabled HARQ process means that the first HARQ process that has been configured to be non-enabled is deactivated.
For example, when the first information field is "1", the first indication information indicates that the non-enabled state of the first HARQ process is activated, and when the first information field is "0", the first indication information indicates that the non-enabled state of the first HARQ process is deactivated. Alternatively, the first indication information indicates that the non-enabled state of the first HARQ process is activated when the first information field is "0", and indicates that the non-enabled state of the first HARQ process is deactivated when the first information field is "1".
Optionally, when the second indication information includes an identifier of an HARQ process set where the first HARQ process is located, if the information in the first information field is first preset information, a non-enabled state of all HARQ processes in the first HARQ process set is activated; if the information in the first information field is the second preset information, the non-enabled states of all HARQ processes in the first HARQ process set are deactivated. The first HARQ process set is the HARQ process set where the first HARQ process is located.
For example, when the second indication information includes an identifier of a HARQ process set where the first HARQ process is located (hereinafter referred to as a first HARQ process set), the first indication information indicates that all non-enabled states of HARQ processes in the first HARQ process set are activated when the first information field is "1", and the first indication information indicates that all non-enabled states of HARQ processes in the first HARQ process set are deactivated when the first information field is "0". Or when the first information field is "0", the first indication information indicates that the non-enabled states of the HARQ processes in the first HARQ process set are activated, and when the first information field is "1", the first indication information indicates that the non-enabled states of the HARQ processes in the first HARQ process set are all deactivated.
Next, the second parameter information will be described with reference to table 6.
TABLE 6
| Information domain | DCI Format 1_0 or DCI Format 1_2 | DCI Format 1_1 |
| Redundancy version | All set to 0 | For enabled transport blocks: all set to 0 |
For example, assuming that the second indication information is DCI, the first information field is a redundancy version information field in the DCI. When the format of the DCI is DCI format 1_0 or DCI format 1_2, when the information in the redundancy version information field is all set to 0, the inactive state of the first HARQ process (or the HARQ process where the first HARQ process is active) is activated. When the format of the DCI is DCI format 1_1, for an enabled transport block, the non-enabled state of the first HARQ process (or the set of HARQ processes where the first HARQ process is located) is activated when the information in the redundancy version information field is all set to 0. The first HARQ process or the set of HARQ processes where the first HARQ process is located may also be indicated by a HARQ process number information field in the DCI. Optionally, the DCI is a CS-RNTI scrambling code DCI. Optionally, an NDI field corresponding to the enabled transport block TB in the DCI is set to "1".
Next, the second parameter information will be described with reference to table 7.
TABLE 7
For example, assuming that the second indication information is DCI, the first information field is a redundancy version information field in the DCI. When the format of the DCI is DCI format 1_0 or DCI format 1_2, when the information in the redundancy version information field is all set to 1, the inactive state of the first HARQ process (or the HARQ process in which the first HARQ process is active) is activated. When the format of the DCI is DCI format 1_1, for an enabled transport block, the non-enabled state of the first HARQ process (or the set of HARQ processes where the first HARQ process is located) is activated when the information in the redundancy version information field is all set to 0. The first HARQ process or the set of HARQ processes where the first HARQ process is located may also be indicated by a HARQ process number information field in the DCI.
Case 2, the second parameter information is a combination of information in at least two information domains in the second indication information.
If the combination of the information in at least two information domains is a first information combination, the first HARQ process is an activated non-enabled HARQ process; alternatively, if the combination of information in at least two information fields is a second combination of information, the first HARQ process is a deactivated non-enabled HARQ process. For example, when the second indication information is DCI, the at least two information fields include: redundancy version information field, modulation and coding scheme information field, and frequency domain resource allocation information field in DCI.
Optionally, when the second indication information includes an identifier of an HARQ process set where the first HARQ process is located, if a combination of information in at least two information domains is the first information combination, a non-enabled state of all HARQ processes in the first HARQ process set is activated; if the combination of information in the at least two information fields is a second combination of information, the non-enabled states of all HARQ processes in the first set of HARQ processes are deactivated. The first HARQ process set is the HARQ process set where the first HARQ process is located.
Next, the second parameter information will be described with reference to table 8.
TABLE 8
For example, assuming that the second indication information is DCI, the at least two information fields include: redundancy version information field, modulation and coding scheme information field and frequency domain resource allocation information field, then for DCI of three formats (DCI format 1_0, DCI format 1_1, DCI format 1_2), when the values in the redundancy version information field are all set to 0, the modulation and coding scheme information field are all set to 1, for allocation type 1, the frequency domain resource allocation information field is all set to 0, and for allocation type 2, the non-enabled state of the first HARQ process (or the HARQ process where the first HARQ process is located is activated) is activated. The first HARQ process or the set of HARQ processes where the first HARQ process is located may also be indicated by a HARQ process number information field in the DCI. Optionally, the DCI is a CS-RNTI scrambling code DCI. Optionally, an NDI field corresponding to the enabled transport block TB in the DCI is set to "1".
Next, the second parameter information will be described with reference to table 9.
TABLE 9
For example, assuming that the second indication information is DCI, the at least two information fields include: redundancy version information field, modulation and coding scheme information field and frequency domain resource allocation information field, then for DCI of three formats (DCI format 1_0, DCI format 1_1, DCI format 1_2), when the values in the redundancy version information field are all set to 1, the modulation and coding scheme information field are all set to 0, for allocation type 1, the frequency domain resource allocation information field is all set to 1, and for allocation type 2, the non-enabled state of the first HARQ process (or the HARQ process where the first HARQ process is located is activated) is activated. The first HARQ process or the set of HARQ processes where the first HARQ process is located may also be indicated by a HARQ process number information field in the DCI. Optionally, the DCI is a CS-RNTI scrambling code DCI.
S602, the network equipment sends second indication information to the terminal equipment.
S603, the network equipment determines the HARQ feedback function state of the first HARQ process according to the second indication information.
When the first HARQ process is a downlink HARQ process, if the first HARQ process is in a non-enabled state, the terminal equipment determines that feedback is not carried out on the first HARQ process. If the first HARQ process is in an enabling state, the terminal equipment determines to feed back the first HARQ process.
When the first HARQ process is an uplink HARQ process, if the HARQ feedback function state of the first HARQ process is a non-enabled state, the terminal equipment does not wait for the feedback of the network equipment to the first physical channel transmitted in the first HARQ process; or if the HARQ feedback function state of the first HARQ process is an enabled state, the terminal device waits for the feedback of the network device to the first physical channel transmitted in the first HARQ process.
In the embodiment shown in fig. 6, in the downlink process, the network device may indicate to the terminal device whether to feed back the first HARQ process through the second indication information; when the terminal equipment determines that the first HARQ process is not fed back according to the second indication information, the terminal equipment does not need to feed back the HARQ process, and the network equipment can transmit other data through the HARQ process without waiting for the feedback of the terminal equipment, so that the data transmission efficiency is improved. In the uplink process, the network device can indicate whether to wait for the feedback of the network device to the first physical channel transmitted in the first HARQ process or not to the terminal device through the second indication information; when the terminal equipment determines not to wait for the feedback of the network equipment to the first physical channel transmitted in the first HARQ process according to the second indication information, after the terminal equipment transmits uplink data through the first HARQ process, the terminal equipment can transmit the uplink data through the first HARQ process without waiting for preset time length, and the data transmission efficiency between the terminal equipment and the network equipment is improved.
Fig. 7 is a flowchart of another method for determining a state of an HARQ process according to an embodiment of the present application. In the embodiment shown in fig. 7, the indication information includes third indication information. Referring to fig. 7, the method may include:
s701, the network device generates third indication information.
The third indication information is used for dynamically indicating the HARQ feedback function state of the first HARQ process.
Optionally, the third indication information is DCI.
The third indication information includes at least one of the following information: the method comprises the steps of identifying a first HARQ process and third parameter information, wherein the third parameter information is used for indicating the HARQ feedback function state of the first HARQ process.
Optionally, the third parameter information is information in a second information domain in the third indication information.
If the information in the second information domain is third preset information, the HARQ feedback function state of the first HARQ process is an enabling state; or if the information in the second information field is fourth preset information, the HARQ feedback function state of the first HARQ process is a non-enabled state. Optionally, the second information field is a feedback time indication field from PDSCH to HARQ.
For example, the second information field is a PDSCH-to-HARQ feedback time indication field (PDSCH-to-harq_ feedback timing indicator). When the network device configures the time sequence from downlink data to uplink HARQ feedback for the terminal device (for example, configures a parameter dl-dataToUL-ACK), configuring a special value (or an invalid value or a non-numeric value), and if the feedback time from PDSCH to HARQ is indicated by the second information field to be the special value, the currently scheduled HARQ process is a non-enabled HARQ process; or if the second information field indicates that the feedback time from the PDSCH to the HARQ is a normal value, the current scheduled HARQ process is an enabled HARQ process.
S702, the network equipment sends third indication information to the terminal equipment.
S703, the network equipment determines the HARQ feedback function state of the first HARQ process according to the third indication information.
When the first HARQ process is a downlink HARQ process, if the first HARQ process is in a non-enabled state, the terminal equipment determines that feedback is not carried out on the first HARQ process. If the first HARQ process is in an enabling state, the terminal equipment determines to feed back the first HARQ process.
When the first HARQ process is an uplink HARQ process, if the HARQ feedback function state of the first HARQ process is a non-enabled state, the terminal equipment does not wait for the feedback of the network equipment to the first physical channel transmitted in the first HARQ process; or if the HARQ feedback function state of the first HARQ process is an enabled state, the terminal device waits for the feedback of the network device to the first physical channel transmitted in the first HARQ process.
In the embodiment shown in fig. 7, in the downlink process, the network device may indicate to the terminal device whether to feed back the first HARQ process through the third indication information; when the terminal equipment determines that the first HARQ process is not fed back according to the third indication information, the terminal equipment does not need to feed back the HARQ process, and the network equipment can transmit other data through the HARQ process without waiting for the feedback of the terminal equipment, so that the data transmission efficiency is improved. In the uplink process, the network device can indicate whether to wait for the feedback of the network device to the first physical channel transmitted in the first HARQ process or not to the terminal device through the third indication information; when the terminal equipment determines not to wait for the feedback of the network equipment to the first physical channel transmitted in the first HARQ process according to the third indication information, after the terminal equipment transmits uplink data through the first HARQ process, the terminal equipment can transmit the uplink data through the first HARQ process without waiting for a preset time length, and the data transmission efficiency between the terminal equipment and the network equipment is improved.
The indication information may further include two or more of the first indication information, the second indication information, or the third indication information. Next, a method for determining the state of the HARQ process between the network device and the terminal device will be described, when the indication information may further include two or more of the first indication information, the second indication information, or the third indication information. The following various ways may be included:
mode 1, the instruction information includes first instruction information and second instruction information.
In this manner, the network device may first send first indication information to the terminal device, where the first indication information may configure a non-enabled HARQ process and/or an enabled HARQ process in the terminal device. After the terminal device receives the first indication information, the non-enabled HARQ process in the terminal device is not activated. The network device also transmits second indication information to the terminal device, where the second indication information is used to activate or deactivate the non-enabled HARQ process configured by the first indication information. Of course, the network device may also send the first indication information and the second indication information to the terminal device at the same time, which is not limited in the present application.
This will be described below with reference to fig. 8 by way of a specific example.
Fig. 8 is a schematic diagram of an HARQ feedback state of an HARQ process according to an embodiment of the present application. It is assumed that 16 HARQ processes are included in the terminal device. Referring to fig. 8, at time t1, the network device may first send first indication information to the terminal device, where the first indication information is used to configure 16 HARQ processes in the terminal device into two HARQ process sets, where the two HARQ process sets are HARQ process set 1 and HARQ process set 2, HARQ process set 1 includes HARQ process 0 to HARQ process 11, and HARQ process set 2 includes HARQ process 12 to HARQ process 15. The first indication information is also used to configure HARQ process set 2 as a non-enabled HARQ process.
At time t2, the network device also transmits second indication information to the terminal device, where the second indication information is used to activate the HARQ process set 2 during the first period (from time t3 to time t 4) or to activate a non-enabled state in the HARQ process set 2. For example, the first period may be determined according to an activation or deactivation signaling (or second indication information), or may be determined according to a preset or configured duration parameter and the second indication information. If the HARQ process in the HARQ process set 2 is a downlink HARQ process, after the terminal device receives the second indication information, the terminal device does not feed back the HARQ process in the HARQ process set 2 in the first period, and feeds back the HARQ process in the HARQ process set 2 in other periods. For example, it is assumed that, in the first period, if the terminal device receives downlink data corresponding to PDSCH 0 (corresponding to HARQ process 13) sent by the network device, the terminal device does not feedback HARQ-ACK information corresponding to the TB in HARQ process 13, and if the terminal device receives downlink data corresponding to PDSCH 1 (corresponding to HARQ process 5) sent by the network device, the terminal device feeds back HARQ-ACK information corresponding to the TB in HARQ process 5.
Mode 2, the indication information includes first indication information and third indication information.
In this manner, the network device may first send first indication information to the terminal device, where the first indication information may configure a non-enabled HARQ process and/or an enabled HARQ process in the terminal device. After the terminal device receives the first indication information, the non-enabled HARQ process in the terminal device is not activated. The network device also transmits third indication information to the terminal device, where the third indication information is used to dynamically indicate that the first HARQ process is in a non-enabled state or an enabled state. Wherein the non-enabled HARQ process dynamically indicated by the third indication information belongs to the non-enabled HARQ process configured by the first indication information. Of course, the network device may also send the first indication information and the third indication information to the terminal device at the same time, which is not limited in the present application.
This will be described below with reference to fig. 9 by way of a specific example.
Fig. 9 is a schematic diagram of an HARQ feedback state of another HARQ process according to an embodiment of the present application. It is assumed that 16 HARQ processes are included in the terminal device. Referring to fig. 9, at time t1, the network device may first send first indication information to the terminal device, where the first indication information is used to configure 16 HARQ processes in the terminal device into two HARQ process sets, where the two HARQ process sets are HARQ process set 1 and HARQ process set 2, HARQ process set 1 includes HARQ process 0 to HARQ process 11, and HARQ process set 2 includes HARQ process 12 to HARQ process 15. The first indication information is also used to configure HARQ process set 2 as a non-enabled HARQ process.
At time t2, it is assumed that the terminal device receives third indication information, for example, the third indication information is DCI, the DCI is used for scheduling PDSCH, and the HARQ process corresponding to the PDSCH belongs to HARQ process set 2. Assuming that the HARQ process in the HARQ process set 2 is a downlink HARQ process, for example, when the PDSCH scheduled by the DCI is PDSCH 0, the PDSCH 0 corresponds to the HARQ process 12, and the feedback time indication field (hereinafter abbreviated as K1 indication or K1) from the PDSCH to the HARQ in the DCI is an invalid value (the invalid value indicates that the terminal device does not feed back the corresponding HARQ process), the terminal device does not need to feed back the HARQ-ACK information corresponding to the TB in the HARQ process 12. For another example, when the PDSCH scheduled by the DCI is PDSCH 0, the PDSCH corresponds to HARQ process 13, and the K1 indication in the DCI is a valid value, the terminal device feeds back HARQ-ACK information corresponding to the TB in this HARQ process 13.
Mode 3, the indication information includes first indication information, second indication information, and third indication information.
In this manner, the network device may first send first indication information to the terminal device, where the first indication information may configure a non-enabled HARQ process and/or an enabled HARQ process in the terminal device. After the terminal device receives the first indication information, the non-enabled HARQ process in the terminal device is not activated. The network device also transmits second indication information to the terminal device, where the second indication information is used to activate or deactivate the non-enabled HARQ process configured by the first indication information. The network device also transmits third indication information to the terminal device, where the third indication information is used to dynamically indicate that the first HARQ process is in a non-enabled state or an enabled state. The non-enabled HARQ process dynamically indicated by the third indication information belongs to the non-enabled HARQ process configured by the first indication information and the non-enabled HARQ process activated by the second indication information. Of course, the network device may also send the first indication information, the second indication information and the third indication information to the terminal device at the same time, which is not limited in the present application.
This will be described below with reference to fig. 10 by way of a specific example.
Fig. 10 is a schematic diagram of an HARQ feedback state of another HARQ process according to an embodiment of the present application. It is assumed that 16 HARQ processes are included in the terminal device. Referring to fig. 10, at time t1, the network device may first send first indication information to the terminal device, where the first indication information is used to configure 16 HARQ processes in the terminal device into two HARQ process sets, where the two HARQ process sets are respectively HARQ process set 1 and HARQ process set 2, HARQ process set 1 includes HARQ process 0 to HARQ process 11, and HARQ process set 2 includes HARQ process 12 to HARQ process 15. The first indication information is also used to configure HARQ process set 2 as a non-enabled HARQ process.
At time t2, the network device further transmits second indication information to the terminal device, where the second indication information is used to activate the non-enabled state of the HARQ process set 2 in the first period (from time t3 to time t 4). The first period may be determined according to an activation or deactivation signaling (or second indication information), or may be determined according to a preset or configured duration parameter and the second indication information.
In the first period, it is assumed that the terminal device receives third indication information, for example, the third indication information is DCI, the DCI is used for scheduling PDSCH, and the HARQ process corresponding to the PDSCH belongs to HARQ process set 2. Assuming that the HARQ process in the HARQ process set 2 is a downlink HARQ process, for example, when the PDSCH scheduled by the DCI is PDSCH0, the pdsch0 corresponds to the HARQ process 12, and the feedback time indication field (hereinafter abbreviated as K1 indication or K1) from the PDSCH to the HARQ in the DCI is an invalid value (the invalid value indicates that the terminal device does not feed back the corresponding HARQ process), the terminal device does not need to feed back the HARQ-ACK information corresponding to the TB in the HARQ process 12. For example, when the PDSCH scheduled by the DCI is PDSCH0, the PDSCH corresponds to HARQ process 13, and the K1 indication in the DCI is a valid value, the terminal device feeds back HARQ-ACK information corresponding to the TB in the HARQ process 13.
Mode 4, the instruction information includes second instruction information and third instruction information.
In this manner, the network device may first send second indication information to the terminal device, where the second indication information may activate a non-enabled HARQ process in the terminal device, where the non-enabled HARQ process in the terminal device may be configured in advance for the terminal device by the network device, or configured in advance by the terminal device, or agreed by a protocol, or indicated by the second indication information. The network device may also send third indication information to the terminal device, where the third indication information is used to dynamically indicate that the first HARQ process is in a non-enabled state or an enabled state. Wherein the non-enabled HARQ process dynamically indicated by the third indication information belongs to the non-enabled HARQ process activated by the second indication information. Of course, the network device may also send the second indication information and the third indication information to the terminal device at the same time, which is not limited in the present application.
This will be described below with reference to fig. 11 by way of a specific example.
Fig. 11 is a schematic diagram of an HARQ feedback state of another HARQ process according to an embodiment of the present application. It is assumed that 16 HARQ processes are included in the terminal device. At time t1, the network device sends second indication information to the terminal device, where the second indication information indicates that HARQ process 0 to HARQ process 11 are feedback enabled HARQ processes, HARQ process 12 to HARQ process 15 are disabled HARQ processes, and the second indication information further indicates that HARQ process 12 to HARQ process 15 are enabled for a first period of time (time t2 to time t 3). The first period may be determined according to an activation or deactivation signaling (or second indication information), or may be determined according to a preset or configured duration parameter and the second indication information.
In the first period, it is assumed that the terminal device receives third indication information, for example, the third indication information is DCI, the DCI is used for scheduling PDSCH, and the HARQ process corresponding to the PDSCH belongs to HARQ process set 2. Assuming that the HARQ process in the HARQ process set 2 is a downlink HARQ process, for example, when the PDSCH scheduled by the DCI is PDSCH0, the pdsch0 corresponds to the HARQ process 12, and the feedback time indication field (hereinafter abbreviated as K1 indication or K1) from the PDSCH to the HARQ in the DCI is an invalid value (the invalid value indicates that the terminal device does not feed back the corresponding HARQ process), the terminal device does not need to feed back the HARQ-ACK information corresponding to the TB in the HARQ process 12. For example, when the PDSCH scheduled by the DCI is PDSCH0, the PDSCH corresponds to HARQ process 13, and the K1 indication in the DCI is a valid value, the terminal device feeds back HARQ-ACK information corresponding to the TB in the HARQ process 13.
Fig. 12 is a schematic structural diagram of a device for determining a state of an HARQ process according to an embodiment of the present application. The state determining apparatus 10 of the HARQ process may be applied to a terminal device. Referring to fig. 12, the state determining apparatus 10 of the HARQ process may include a receiving module 11 and a processing module 12, wherein,
