Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and more particularly, to a transmission control method, a PDSCH receiving method, a transmission control device, a PDSCH receiving device, a communication device, and a computer-readable storage medium. Background Art

[0002] In the communication process between a base station and a terminal, the base station may send a PDSCH (Physical Downlink Shared Channel) to the terminal, and the terminal may send HARQ (Hybrid Automatic Repeat request) information to the base station to notify the base station whether the terminal has successfully decoded the PDSCH.

[0003] The HARQ information may be sent through PUCCH (Physical Uplink Control Channel) resources. The PUCCH resources used to send HARQ may be determined based on K1. When the PUCCH resources indicated by K1 for sending HARQ are unavailable, or this feedback operation is discarded, or a retransmission is triggered, or this feedback operation is delayed, these situations will all affect the delay and reliability of HARQ feedback.

[0004] In a CA (Carrier Aggregation) communication scenario, the terminal may send HARQ information on the PUCCH resources of the primary carrier. If the PUCCH resources on the primary carrier are temporarily unavailable due to the above-mentioned several situations, the terminal may be instructed to switch to the secondary carrier to send HAQR information, thereby reducing the HARQ information feedback delay and improving the reliability of HARQ information feedback.

[0017] According to a twelfth aspect of the embodiments of the present disclosure, a PDSCH receiving device is provided, including one or more processors configured to perform: receiving a first trigger message and a second trigger message sent by a base station; where the first trigger message is used to trigger the terminal to switch to a secondary carrier to send HARQ corresponding to a first PDSCH, and the second trigger message is used to trigger the terminal to switch to the secondary carrier to send HARQ corresponding to a second PDSCH; when the time domain resource for sending the first PDSCH is earlier than the time domain resource for sending the second PDSCH, the sending time of the first trigger message is earlier than the sending time of the second trigger message.

[0023] According to an embodiment of the present disclosure, when the sending time of the first trigger message is earlier than the sending time of the second trigger message, the base station can ensure that the terminal first sends the HARQ information corresponding to the first PDSCH to the base station and then sends the HARQ information corresponding to the second PDSCH to the base station by setting the first time-domain resource earlier than the second time-domain resource, for example, by configuring the first trigger message and the second trigger message, so that the base station can correctly determine the HARQ information corresponding to the first trigger message received first as the HARQ information corresponding to the first PDSCH.

[0040] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0041] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure. The singular forms "a" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms unless the context clearly dictates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0042] It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0043] For the purpose of simplicity and ease of understanding, the terms "greater than" or "less than", "higher than" or "lower than" are used herein to represent the size relationship. However, for those skilled in the art, it can be understood that the term "greater than" also covers the meaning of "greater than or equal to", and the term "less than" also covers the meaning of "less than or equal to"; the term "higher than" covers the meaning of "higher than or equal to", and the term "lower than" also covers the meaning of "lower than or equal to".

[0044] In one embodiment, the base station may send PDSCH to the terminal, and the terminal may send HARQ information to the base station to notify the base station whether the terminal has successfully decoded the PDSCH. For example, if the PDSCH is successfully decoded, the HARQ information sent to the base station is ACK; if the PDSCH is not successfully decoded, the HARQ information sent to the base station is NACK.

[0045] In one embodiment, the base station and the terminal may communicate in a carrier aggregation (CA) scenario, and the terminal may send HARQ information on the PUCCH resource of the primary carrier (the carrier of the primary cell).

[0046] However, in some cases, the PUCCH resource for sending HARQ information is temporarily unavailable. To avoid excessive delay in HARQ feedback, the base station may send a trigger message to the terminal to trigger the terminal to switch to the resource of the secondary carrier (the carrier of the secondary cell) to send HARQ information.

[0047] In the above process, the base station and the terminal need to perform multiple operations. The base station sends a Physical Downlink Shared Channel (PDSCH) to the terminal. When the resources for sending Hybrid Automatic Repeat reQuest (HARQ) information on the primary carrier are unavailable, it also needs to send a trigger message to the terminal. The terminal needs to receive the PDSCH. When the resources for sending HARQ information on the primary carrier are unavailable, it also needs to receive the trigger message and switch to a secondary carrier to send HARQ information according to the trigger message.

[0048] Since the base station can send the PDSCH to the terminal multiple times, each PDSCH will trigger the base station and the terminal to perform the above multiple operations, which may lead to a disorder in the execution order of the operations, thus causing some technical problems.

[0049] For example, for two PDSCHs sent by the base station to the terminal, the first PDSCH and the second PDSCH, if the base station first sends the first PDSCH to the terminal and then sends the second PDSCH to the terminal, but the trigger information sent to the terminal triggers the terminal to switch to the secondary carrier to feedback HARQ information, the HARQ information corresponding to the second PDSCH is first fed back by the terminal to the base station, and the HARQ information corresponding to the first PDSCH is then fed back by the terminal to the base station. This is not allowed on the base station side.

[0050] The following embodiments mainly exemplarily illustrate the technical solutions of the present disclosure for the case where the base station sends two PDSCHs to the terminal.

[0051] Figure 1 FIG. is a schematic flowchart of a transmission control method shown according to an embodiment of the present disclosure. The transmission control method shown in this embodiment can be executed by a base station, and the base station can communicate with a terminal. The terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The base station includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0052] As Figure 1 shown, the transmission control method may include the following steps:

[0053] In step S101, send a first Physical Downlink Shared Channel (PDSCH) to the terminal on the primary carrier, and determine a first process number of Hybrid Automatic Repeat reQuest (HARQ) corresponding to the first PDSCH;

[0054] In step S102, before receiving the HARQ information of the first process number sent by the terminal on the secondary carrier, do not send a second PDSCH to the terminal, where the process number of HARQ corresponding to the second PDSCH is the same process number as the first process number, and the secondary carrier is used for the terminal to send HARQ of the process number.

[0055] In one embodiment, when the base station sends a PDSCH to the terminal, it may determine the process number of the HARQ corresponding to the PDSCH, and the process number corresponding to the PDSCH may be configured by the base station. The HARQ information sent by the terminal to the base station for the PDSCH may have a corresponding process number.

[0056] In this embodiment, in order to distinguish the process numbers corresponding to different PDSCHs, the HARQ process number corresponding to the first PDSCH is called the first process number, and the HARQ process number corresponding to the second PDSCH is called the second process number. The first PDSCH and the second PDSCH are different PDSCHs (for example, the carried information is different).

[0057] Figure 2 It is a time-domain relationship diagram of a PDSCH and HARQ information shown according to an embodiment of the present disclosure.

[0058] As Figure 2 shown, after the base station sends the first PDSCH to the terminal on the primary carrier, if the base station has not received the HARQ information of the first process number sent by the terminal on the secondary carrier, and then sends the second PDSCH to the terminal on the primary carrier, that is, the moment t2 when the HARQ information corresponding to the first PDSCH is received is later than the moment t1 when the second PDSCH is sent to the terminal, and when the second process number of the HARQ corresponding to the second PDSCH is the same as the first process number, this is not allowed on the base station side.

[0059] According to an embodiment of the present disclosure, before the base station receives the HARQ information of the first process number sent by the terminal on the secondary carrier, it will not send a second PDSCH with the same HARQ process number as the first process number to the terminal, so as to ensure communication with the terminal according to the logic allowed by the base station.

[0060] Among them, before the base station receives the HARQ information of the first process number sent by the terminal on the secondary carrier, if it sends a second PDSCH to the terminal, the HARQ process number corresponding to the second PDSCH is different from the first process number; or, after the base station receives the HARQ information of the first process number sent by the terminal on the secondary carrier, it sends a second PDSCH with the same process number as the first process number to the terminal.

[0061] In one embodiment, the HARQ information includes at least one of the following: HARQ information for confirming successful decoding of the PDSCH, HARQ information for confirming successful non-reception of the PDSCH.

[0062] When the terminal confirms successful decoding of the PDSCH, the HARQ information sent to the terminal can be HARQ acknowledgement information, that is, HARQ-ACK; when the terminal confirms unsuccessful decoding of the PDSCH, the HARQ information sent to the terminal can be HARQ negative information, that is, HARQ-NACK.

[0063] Figure 3 It is a schematic flowchart of another transmission control method shown according to an embodiment of the present disclosure. As Figure 3 shown, the method further includes:

[0064] In step S301, a first trigger message and / or a second trigger message are sent to the terminal;

[0065] Wherein, the first trigger message is used to trigger the terminal to switch to a secondary carrier to send HARQ information corresponding to the first PDSCH at a first moment, and the second trigger message is used to trigger the terminal to switch to a secondary carrier to send HARQ information corresponding to the second PDSCH at a second moment.

[0066] In one embodiment, when the base station sends the first PDSCH and the second PDSCH to the terminal, the first trigger message and / or the second trigger message may also be sent to the terminal as needed.

[0067] For example, when the PUCCH resource for sending HARQ information corresponding to the first PDSCH on the primary carrier is temporarily unavailable, a first trigger message can be sent to the terminal to trigger the terminal to switch to a secondary carrier to send HARQ information corresponding to the first PDSCH. For example, it can be switched at the first moment, and this moment can be configured by the base station as needed.

[0068] For example, when the PUCCH resource for sending HARQ information corresponding to the second PDSCH on the primary carrier is temporarily unavailable, a second trigger message can be sent to the terminal to trigger the terminal to switch to a secondary carrier to send HARQ information corresponding to the second PDSCH. For example, it can be switched at the second moment, and this moment can be configured by the base station as needed.

[0069] It should be noted that the secondary carriers indicated by the first trigger message and the second trigger message for the terminal to switch to can be the same or different, and are specifically configured by the base station as needed.

[0070] In one embodiment, the resource being temporarily unavailable may include one of the following situations: the resource is unavailable, this feedback operation is discarded, retransmission is triggered, or this feedback operation is delayed.

[0071] Figure 4It is a schematic flowchart of a transmission control method shown according to an embodiment of the present disclosure. The transmission control method shown in this embodiment can be executed by a base station, and the base station can communicate with a terminal. The terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The base station includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0072] As Figure 4 shown, the transmission control method may include the following steps:

[0073] In step S401, a first PDSCH, a second PDSCH, a first trigger message, and a second trigger message are sent to the terminal on the primary carrier, where the first trigger message is used to trigger the terminal to switch to the secondary carrier to send HARQ information corresponding to the first PDSCH, and the second trigger message is used to trigger the terminal to switch to the secondary carrier to send HARQ information corresponding to the second PDSCH;

[0074] In step S402, the HARQ information corresponding to the first PDSCH sent by the terminal is received on the first time-domain resource of the secondary carrier, and the HARQ information corresponding to the second PDSCH sent by the terminal is received on the second time-domain resource of the secondary carrier, where in the case where the sending time of the first trigger message is earlier than the sending time of the second trigger message, the first time-domain resource is earlier than the second time-domain resource.

[0075] In one embodiment, the base station may send a first PDSCH and a second PDSCH to the terminal, and may also send a first trigger message and a second trigger message to the terminal.

[0076] For example, when the PUCCH resource for sending HARQ information corresponding to the first PDSCH on the primary carrier is temporarily unavailable, a first trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to send HARQ information corresponding to the first PDSCH.

[0077] For example, when the PUCCH resource for sending HARQ information corresponding to the second PDSCH on the primary carrier is temporarily unavailable, a second trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to send HARQ information corresponding to the second PDSCH.

[0078] In one embodiment, the terminal may switch to the secondary carrier to send HARQ information corresponding to the first PDSCH and HARQ information corresponding to the second PDSCH to the terminal. The base station may receive the HARQ information corresponding to the first PDSCH sent by the terminal on the first time-domain resource of the secondary carrier, and receive the HARQ information corresponding to the second PDSCH sent by the terminal on the second time-domain resource of the secondary carrier.

[0079] Figure 5 It is a time-domain relationship diagram of a trigger message and HARQ information shown according to an embodiment of the present disclosure.

[0080] As Figure 5 shown, when the transmission time t1' of the first trigger message sent by the base station is earlier than the transmission time t2' of the second trigger message sent by the base station, that is, the base station first sends the first trigger message and then sends the second trigger message. Generally, the base station will default that the HARQ information corresponding to the first trigger message is received first, and the HARQ information corresponding to the second trigger message is received later.

[0081] If the first time-domain resource t4' is later than the second time-domain resource t3', that is, the terminal first sends the HARQ information corresponding to the second PDSCH to the base station and then sends the HARQ information corresponding to the first PDSCH to the base station, which is not allowed on the base station side.

[0082] According to an embodiment of the present disclosure, when the transmission time of the first trigger message is earlier than the transmission time of the second trigger message, the base station can ensure that the terminal first sends the HARQ information corresponding to the first PDSCH to the base station and then sends the HARQ information corresponding to the second PDSCH to the base station by setting the first time-domain resource earlier than the second time-domain resource, for example, by configuring the first trigger message and the second trigger message. Thus, the base station can correctly determine the HARQ information corresponding to the first trigger message received first as the HARQ information corresponding to the first PDSCH.

[0083] In one embodiment, the base station can also set the transmission time of the second trigger message to be later than the first time-domain resource as needed. That is, the base station can send the second trigger message to the terminal only after receiving the HARQ information corresponding to the first PDSCH in the first time-domain resource. Then the terminal can send the HARQ information corresponding to the first PDSCH to the base station, thereby ensuring that the second time-domain resource for the base station to receive the HARQ information corresponding to the second PDSCH is necessarily later than the first time-domain resource, and further ensuring that the base station can correctly determine the HARQ information corresponding to the first PDSCH received first as the HARQ information corresponding to the first trigger message, that is, the HARQ information corresponding to the first PDSCH.

[0084] In one embodiment, the first time-domain resource includes the end position of the HARQ information corresponding to the first PDSCH in the time domain, and the second time-domain resource includes the end position of the HARQ information corresponding to the first PDSCH in the time domain.

[0085] It should be noted that the meanings expressed by the first time-domain resource and the second time-domain resource can be determined as needed. For example, it can be asFigure 5 As shown, the first time-domain resource is the start position of the HARQ information corresponding to the first PDSCH in the time domain, and the second time-domain resource is the start position of the HARQ information corresponding to the second PDSCH in the time domain. It is also possible to set the first time-domain resource as the end position of the HARQ information corresponding to the first PDSCH in the time domain, and the second time-domain resource as the start position of the HARQ information corresponding to the second PDSCH in the time domain.

[0086] In one embodiment, when the time-domain resource for transmitting the first PDSCH is earlier than the time-domain resource for transmitting the second PDSCH, the transmission time of the first trigger message is earlier than the transmission time of the second trigger message.

[0087] In one embodiment, when the time-domain resource for the base station to transmit the first PDSCH is earlier than the time-domain resource for transmitting the second PDSCH, it is possible to set the transmission time of the first trigger message to be earlier than the transmission time of the second trigger message, so that when the terminal first receives the first PDSCH and then receives the second PDSCH, it can first receive the first trigger message and then receive the second trigger message, and then accurately trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH according to the first trigger message.

[0088] Figure 6 It is a schematic flowchart of a transmission control method shown according to an embodiment of the present disclosure. The transmission control method shown in this embodiment can be executed by a base station, and the base station can communicate with a terminal. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and Internet of Things devices. The base station includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0089] As Figure 6 shown, the transmission control method may include the following steps:

[0090] In step S601, send a first trigger message and a second trigger message to the terminal; wherein, the first trigger message is used to trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH, and the second trigger message is used to trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the second PDSCH; when the time-domain resource for transmitting the first PDSCH is earlier than the time-domain resource for transmitting the second PDSCH, the transmission time of the first trigger message is earlier than the transmission time of the second trigger message.

[0091] In one embodiment, the base station may send a first PDSCH and a second PDSCH to the terminal, and may also send a first trigger message and a second trigger message to the terminal. Among them, the first trigger message and the second trigger message may be sent on PDCCH (Physical Downlink Control Channel) resources.

[0092] For example, when the PUCCH resource for sending the HARQ information corresponding to the first PDSCH on the primary carrier is temporarily unavailable, a first trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to send the HARQ information corresponding to the first PDSCH.

[0093] For example, when the PUCCH resource for sending the HARQ information corresponding to the second PDSCH on the primary carrier is temporarily unavailable, a second trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to send the HARQ information corresponding to the second PDSCH.

[0094] Figure 7 It is a time-domain relationship diagram of a PDSCH and a trigger message shown according to an embodiment of the present disclosure.

[0095] As Figure 7 shown, in the case where the time-domain resource t1” for sending the first PDSCH is earlier than the time-domain resource t2” for sending the second PDSCH, if the first moment t3” is later than the second moment t4”, that is, the base station first sends the first PDSCH to the terminal and then sends the second PDSCH to the terminal, if the sending moment of the first trigger message is later than the sending moment of the second trigger message, it will cause the terminal to receive the first PDSCH first and then the second PDSCH, but receive the second trigger message first and then the first trigger message. This is not allowed on the base station side.

[0096] According to an embodiment of the present disclosure, in the case where the time-domain resource for the base station to send the first PDSCH is earlier than the time-domain resource for sending the second PDSCH, the sending moment of the first trigger message may be set earlier than the sending moment of the second trigger message to ensure that when the terminal receives the first PDSCH first and then the second PDSCH, it can receive the first trigger message first and then the second trigger message, and then accurately trigger the terminal to switch to the secondary carrier to send the HARQ corresponding to the first PDSCH according to the first trigger message.

[0097] In one embodiment, the first trigger message triggers the terminal to switch to the secondary carrier to send the HARQ corresponding to the first PDSCH at a first moment, and the second trigger message triggers the terminal to switch to the secondary carrier to send the HARQ corresponding to the second PDSCH at a second moment;

[0098] In the case where the time domain resource for sending the first trigger message is earlier than the time domain resource for sending the second trigger message, the first moment is earlier than the second moment.

[0099] In one embodiment, the first trigger message may trigger the terminal to switch to a secondary carrier to send the HARQ corresponding to the first PDSCH at a first moment, and the second trigger message may trigger the terminal to switch to a secondary carrier to send the HARQ corresponding to the second PDSCH at a second moment. The first moment and the second moment may be set by the base station as needed.

[0100] According to an embodiment of the present disclosure, in the case where the time domain resource for sending the first trigger message is earlier than the time domain resource for sending the second trigger message, the first moment may be set earlier than the second moment. Accordingly, it can be ensured that when the terminal first receives the first trigger message and then receives the second trigger message, the first moment at which the first trigger message triggers the terminal to send HARQ is also earlier than the second moment at which the second trigger message triggers the terminal to send HARQ, so as to accurately switch to the secondary carrier according to the first moment to send the HARQ corresponding to the first trigger message, that is, the HARQ corresponding to the first PDSCH.

[0101] Figure 8 It is a time domain relationship diagram of a trigger message and HARQ information shown according to an embodiment of the present disclosure.

[0102] As Figure 8 shown, the base station may set the transmission time T3 of the second trigger message to be later than the first time domain resource T2 as needed. That is, when the base station first sends the first trigger message at T1 and then discovers the second trigger message at T2, it may send the second trigger message to the terminal only after receiving the HARQ information corresponding to the first PDSCH in the first time domain resource. Then the terminal can send the HARQ information corresponding to the first PDSCH to the base station, so as to ensure that the first moment T2 at which the first trigger message triggers the terminal to send HARQ is necessarily earlier than the second moment T4 at which the second trigger message triggers the terminal to send HARQ, and further ensure that the terminal can accurately switch to the secondary carrier according to the first moment to send the HARQ corresponding to the first trigger message, that is, the HARQ corresponding to the first PDSCH.

[0103] In one embodiment, in the case where the transmission time of the first trigger message is earlier than the transmission time of the second trigger message, the first time domain resource is earlier than the second time domain resource.

[0104] In one embodiment, when the transmission time of the first trigger message is earlier than that of the second trigger message, the base station can ensure that the terminal first sends the HARQ information corresponding to the first PDSCH to the base station and then sends the HARQ information corresponding to the second PDSCH to the base station by setting the first time-domain resource earlier than the second time-domain resource, for example, by configuring the first trigger message and the second trigger message, so that the base station can correctly determine the HARQ information corresponding to the first trigger message received first as the HARQ information corresponding to the first PDSCH.

[0105] Figure 9 FIG. 4 is a schematic flowchart of a method for receiving a PDSCH according to an embodiment of the present disclosure. The transmission control method shown in this embodiment may be executed by a terminal, and the terminal may communicate with a base station. The terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The base station includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0106] As Figure 9 shown, the transmission control method may include the following steps:

[0107] In step S901, receive a first PDSCH sent by a base station on a primary carrier, where the first process number of the HARQ corresponding to the first PDSCH;

[0108] In step S902, before sending HARQ information of the first process number to the base station on a secondary carrier, do not receive a second PDSCH sent by the base station, where the process number of the HARQ corresponding to the second PDSCH is the same as the first process number, and the secondary carrier is used by the terminal to send HARQ of the process number.

[0109] In one embodiment, when the base station sends a PDSCH to the terminal, it may determine the process number of the HARQ corresponding to the PDSCH, and the process number corresponding to the PDSCH may be configured by the base station. The HARQ information sent by the terminal to the base station for the PDSCH may have a corresponding process number.

[0110] In this embodiment, to distinguish the process numbers corresponding to different PDSCHs, the HARQ process number corresponding to the first PDSCH is called the first process number, and the HARQ process number corresponding to the second PDSCH is called the second process number. The first PDSCH and the second PDSCH are different PDSCHs (for example, the carried information is different).

[0111] As Figure 2As shown, after the base station sends the first PDSCH to the terminal on the primary carrier, if the base station has not received the HARQ information of the first process number sent by the terminal on the secondary carrier, it sends the second PDSCH to the terminal on the primary carrier. That is, the time t2 when the HARQ information corresponding to the first PDSCH is received is later than the time t1 when the second PDSCH is sent to the terminal, and when the second process number of the HARQ corresponding to the second PDSCH is the same as the first process number, it will cause the terminal to mistakenly think that the second PDSCH is a retransmission of the first PDSCH.

[0112] According to an embodiment of the present disclosure, after the base station sends the first PDSCH to the terminal on the primary carrier, it will send the second PDSCH to the terminal on the primary carrier only if it receives the HARQ information of the first process number sent by the terminal on the secondary carrier. Among them, the second process number of the HARQ corresponding to the second PDSCH can be the same as the first process number. Since the base station has received the HARQ information of the first process number, that is, the action of the terminal side to feedback HARQ for the first PDSCH has been completed, when sending the second PDSCH to the terminal again, even if the same process number as the first process number is used, it will not be mistaken by the terminal as a retransmission of the first PDSCH.

[0113] Furthermore, after the base station sends the first PDSCH to the terminal on the primary carrier, if the base station has not received the HARQ information of the first process number sent by the terminal on the secondary carrier and sends the second PDSCH to the terminal on the primary carrier, then the second process number of the HARQ corresponding to the second PDSCH can be set to a different process number from the first process number, so that when the terminal has not completed the action of feedback HARQ for the first PDSCH, it can distinguish different PDSCHs according to the process number.

[0114] In one embodiment, the HARQ information includes at least one of the following: HARQ information for confirming successful decoding of the PDSCH, HARQ information for confirming successful non-reception of the PDSCH.

[0115] When the terminal confirms successful decoding of the PDSCH, the HARQ information sent to the terminal can be HARQ confirmation information, that is, HARQ-ACK; when the terminal confirms unsuccessful decoding of the PDSCH, the HARQ information sent to the terminal can be HARQ negative information, that is, HARQ-NACK.

[0116] Figure 10 It is a schematic flowchart of another PDSCH receiving method shown according to an embodiment of the present disclosure. As Figure 10 shown, the method further includes:

[0117] In step S1001, receive the first trigger message and / or the second trigger message sent by the base station;

[0118] Wherein, the first trigger message is used to trigger the terminal to switch to a secondary carrier at a first moment to send HARQ information corresponding to the first PDSCH, and the second trigger message is used to trigger the terminal to switch to a secondary carrier at a second moment to send HARQ information corresponding to the second PDSCH.

[0119] In one embodiment, when the base station sends the first PDSCH and the second PDSCH to the terminal, it may also send the first trigger message and / or the second trigger message to the terminal as needed.

[0120] For example, when the PUCCH resource for sending HARQ information corresponding to the first PDSCH on the primary carrier is temporarily unavailable, the first trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to send HARQ information corresponding to the first PDSCH. For example, it may switch at the first moment, and this moment can be configured by the base station as needed.

[0121] For example, when the PUCCH resource for sending HARQ information corresponding to the second PDSCH on the primary carrier is temporarily unavailable, the second trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to send HARQ information corresponding to the second PDSCH. For example, it may switch at the second moment, and this moment can be configured by the base station as needed.

[0122] It should be noted that the secondary carriers indicated by the first trigger message and the second trigger message for the terminal to switch to may be the same or different, which is specifically configured by the base station as needed.

[0123] In one embodiment, the resource being temporarily unavailable may include one of the following situations: the resource is unavailable, discard this feedback operation, trigger retransmission, and delay this feedback operation.

[0124] Figure 11 It is a schematic flowchart of a PDSCH receiving method shown according to an embodiment of the present disclosure. The transmission control method shown in this embodiment can be executed by a terminal, and the terminal can communicate with a base station. The terminal includes but is not limited to communication devices such as mobile phones, tablets, wearable devices, sensors, and Internet of Things devices. The base station includes but is not limited to base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0125] As Figure 11 shown, the transmission control method may include the following steps:

[0126] In step S1101, the first PDSCH, the second PDSCH, the first trigger message, and the second trigger message sent by the base station are received on the primary carrier, where the first trigger message is used to trigger the terminal to switch to the secondary carrier to send the HARQ information corresponding to the first PDSCH, and the second trigger message is used to trigger the terminal to switch to the secondary carrier to send the HARQ information corresponding to the second PDSCH;

[0127] In step S1102, the HARQ information corresponding to the first PDSCH is sent to the base station on the first time-domain resource of the secondary carrier, and the HARQ information corresponding to the second PDSCH is sent to the base station on the second time-domain resource of the secondary carrier. Wherein, when the sending time of the first trigger message is earlier than the sending time of the second trigger message, the first time-domain resource is earlier than the second time-domain resource.

[0128] In one embodiment, the base station may send the first PDSCH and the second PDSCH to the terminal, and may also send the first trigger message and the second trigger message to the terminal.

[0129] For example, when the PUCCH resource for sending the HARQ information corresponding to the first PDSCH on the primary carrier is temporarily unavailable, the first trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to send the HARQ information corresponding to the first PDSCH.

[0130] For example, when the PUCCH resource for sending the HARQ information corresponding to the second PDSCH on the primary carrier is temporarily unavailable, the second trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to send the HARQ information corresponding to the second PDSCH.

[0131] In one embodiment, the terminal may switch to the secondary carrier to send the HARQ information corresponding to the first PDSCH and the HARQ information corresponding to the second PDSCH to the terminal. The base station may receive the HARQ information corresponding to the first PDSCH sent by the terminal on the first time-domain resource of the secondary carrier, and receive the HARQ information corresponding to the second PDSCH sent by the terminal on the second time-domain resource of the secondary carrier.

[0132] As Figure 5 shown, when the sending time t1' of the first trigger message sent by the base station is earlier than the sending time t2' of the second trigger message sent by the base station, that is, the base station sends the first trigger message first and then the second trigger message. Generally, the base station will default that the HARQ information corresponding to the first trigger message is received first, and the HARQ information corresponding to the second trigger message is received later.

[0133] If the first time-domain resource t4' is later than the second time-domain resource t3', that is, the terminal first sends the HARQ information corresponding to the second PDSCH to the base station and then sends the HARQ information corresponding to the first PDSCH to the base station, it will cause the base station to misidentify the HARQ information corresponding to the second PDSCH as the HARQ information corresponding to the first trigger message, that is, the HARQ information corresponding to the first PDSCH.

[0134] According to an embodiment of the present disclosure, when the sending time of the first trigger message is earlier than the sending time of the second trigger message, the base station can ensure that the terminal first sends the HARQ information corresponding to the first PDSCH to the base station and then sends the HARQ information corresponding to the second PDSCH to the base station by setting the first time-domain resource earlier than the second time-domain resource, for example, by configuring the first trigger message and the second trigger message. Thereby, the base station can correctly determine the HARQ information corresponding to the first PDSCH received first as the HARQ information corresponding to the first trigger message, that is, the HARQ information corresponding to the first PDSCH.

[0135] In one embodiment, the base station can also set the sending time of the second trigger message to be later than the first time-domain resource as needed. That is, the base station can send the second trigger message to the terminal only after receiving the HARQ information corresponding to the first PDSCH in the first time-domain resource. Then the terminal can send the HARQ information corresponding to the first PDSCH to the base station, thereby ensuring that the second time-domain resource for the base station to receive the HARQ information corresponding to the second PDSCH is necessarily later than the first time-domain resource. Furthermore, it is ensured that the base station can correctly determine the HARQ information corresponding to the first PDSCH received first as the HARQ information corresponding to the first trigger message, that is, the HARQ information corresponding to the first PDSCH.

[0136] In one embodiment, the first time-domain resource includes the end position of the HARQ information corresponding to the first PDSCH in the time domain, and the second time-domain resource includes the end position of the HARQ information corresponding to the first PDSCH in the time domain.

[0137] It should be noted that the meanings respectively expressed by the first time-domain resource and the second time-domain resource can be determined as needed. For example, as Figure 5 shown, the first time-domain resource is the start position of the HARQ information corresponding to the first PDSCH in the time domain, and the second time-domain resource is the start position of the HARQ information corresponding to the second PDSCH in the time domain. It is also possible to set the first time-domain resource as the end position of the HARQ information corresponding to the first PDSCH in the time domain and the second time-domain resource as the start position of the HARQ information corresponding to the second PDSCH in the time domain.

[0138] In one embodiment, when the time-domain resource for transmitting the first PDSCH is earlier than the time-domain resource for transmitting the second PDSCH, the transmission time of the first trigger message is earlier than the transmission time of the second trigger message.

[0139] In one embodiment, when the time-domain resource for the base station to transmit the first PDSCH is earlier than the time-domain resource for transmitting the second PDSCH, the transmission time of the first trigger message can be set earlier than the transmission time of the second trigger message, ensuring that when the terminal first receives the first PDSCH and then receives the second PDSCH, it can first receive the first trigger message and then receive the second trigger message, and then accurately trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH according to the first trigger message.

[0140] Figure 12 FIG. is a schematic flowchart of a PDSCH receiving method shown according to an embodiment of the present disclosure. The transmission control method shown in this embodiment can be executed by a terminal, and the terminal can communicate with a base station. The terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The base station includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.

[0141] As Figure 12 shown, the transmission control method may include the following steps:

[0142] In step S1201, receive a first trigger message and a second trigger message sent by the base station;

[0143] wherein, the first trigger message is used to trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH, and the second trigger message is used to trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the second PDSCH; when the time-domain resource for transmitting the first PDSCH is earlier than the time-domain resource for transmitting the second PDSCH, the transmission time of the first trigger message is earlier than the transmission time of the second trigger message.

[0144] In one embodiment, the base station can send a first PDSCH and a second PDSCH to the terminal, and can also send a first trigger message and a second trigger message to the terminal. Among them, the first trigger message and the second trigger message can be sent on PDCCH resources.

[0145] For example, when the PUCCH resource for transmitting the HARQ information corresponding to the first PDSCH on the primary carrier is temporarily unavailable, a first trigger message can be sent to the terminal to trigger the terminal to switch to the secondary carrier to transmit the HARQ information corresponding to the first PDSCH.

[0146] For example, when the PUCCH resource for transmitting the HARQ information corresponding to the second PDSCH on the primary carrier is temporarily unavailable, a second trigger message may be sent to the terminal to trigger the terminal to switch to the secondary carrier to transmit the HARQ information corresponding to the second PDSCH.

[0147] In one embodiment, when the time domain resource for the base station to transmit the first PDSCH is earlier than the time domain resource for transmitting the second PDSCH, that is, the base station first sends the first PDSCH to the terminal and then sends the second PDSCH to the terminal. If the sending time of the first trigger message is later than the sending time of the second trigger message, it will cause the terminal to receive the first PDSCH first and then the second PDSCH, but receive the second trigger message first and then the first trigger message.

[0148] Since when the terminal receives the first PDSCH first and then the second PDSCH online, it generally defaults that the first received trigger message is used to trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH. When the terminal receives the second trigger message first, it will mistakenly think that the second trigger message is used to trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH, which may lead to problems such as switching to the wrong secondary carrier and switching at the wrong time.

[0149] According to an embodiment of the present disclosure, when the time domain resource for the base station to transmit the first PDSCH is earlier than the time domain resource for transmitting the second PDSCH, the sending time of the first trigger message can be set earlier than the sending time of the second trigger message, so as to ensure that when the terminal receives the first PDSCH first and then the second PDSCH, it can receive the first trigger message first and then the second trigger message, and then accurately trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH according to the first trigger message.

[0150] In one embodiment, the first trigger message triggers the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH at a first time, and the second trigger message triggers the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the second PDSCH at a second time;

[0151] When the time domain resource for sending the first trigger message is earlier than the time domain resource for the second trigger message, the first time is earlier than the second time.

[0152] In one embodiment, the first trigger message can trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the first PDSCH at a first time, and the second trigger message can trigger the terminal to switch to the secondary carrier to transmit the HARQ corresponding to the second PDSCH at a second time. The first time and the second time can be set by the base station according to needs.

[0153] As Figure 7 shown, when the time domain resource t1” for sending the first trigger message is earlier than the time domain resource t2” for the second trigger message, if the first moment is later than the second moment, that is, the base station first sends the first trigger message to the terminal and then sends the second trigger message to the terminal, but the first moment t4” when the first trigger message triggers the terminal to send HARQ is later than the second moment t3” when the second trigger message triggers the terminal to send HARQ.

[0154] Since the terminal generally defaults to switching to the secondary carrier first and sending the HARQ corresponding to the first trigger message when it receives the first trigger message first and then the second trigger message, but when the first moment is later than the second moment, the terminal will wrongly switch to the secondary carrier according to the second moment and send the HARQ corresponding to the first trigger message, that is, the HARQ corresponding to the first PDSCH.

[0155] According to an embodiment of the present disclosure, when the time domain resource for sending the first trigger message is earlier than the time domain resource for the second trigger message, the first moment can be set earlier than the second moment. Accordingly, it can be ensured that when the terminal receives the first trigger message first and then the second trigger message, the first moment when the first trigger message triggers the terminal to send HARQ is also earlier than the second moment when the second trigger message triggers the terminal to send HARQ, so that the terminal can accurately switch to the secondary carrier according to the first moment and send the HARQ corresponding to the first trigger message, that is, the HARQ corresponding to the first PDSCH.

[0156] In one embodiment, the base station can also set the sending moment of the second trigger message to be later than the first time domain resource as needed. That is, the base station can send the second trigger message to the terminal only after receiving the HARQ information corresponding to the first PDSCH in the first time domain resource, and then the terminal can send the HARQ information corresponding to the first PDSCH to the base station, so as to ensure that the first moment when the first trigger message triggers the terminal to send HARQ is necessarily earlier than the second moment when the second trigger message triggers the terminal to send HARQ, and further ensure that the terminal can accurately switch to the secondary carrier according to the first moment and send the HARQ corresponding to the first trigger message, that is, the HARQ corresponding to the first PDSCH.

[0157] In one embodiment, when the sending moment of the first trigger message is earlier than the sending moment of the second trigger message, the first time domain resource is earlier than the second time domain resource.

[0158] In one embodiment, when the transmission time of the first trigger message is earlier than that of the second trigger message, the base station can ensure that the terminal first sends the HARQ information corresponding to the first PDSCH to the base station and then sends the HARQ information corresponding to the second PDSCH to the base station by setting the first time-domain resource earlier than the second time-domain resource, for example, by configuring the first trigger message and the second trigger message. As a result, the base station can correctly determine the HARQ information corresponding to the first trigger message received first as the HARQ information corresponding to the first PDSCH.

[0159] Corresponding to the foregoing embodiments of the transmission control method and the PDSCH receiving method, the present disclosure also provides embodiments of a transmission control device and a PDSCH receiving device.
