Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a transmission method and apparatus. Background Art

[0002] In New Radio (NR), an access network device may periodically allocate downlink resources (Semi-Persistent Scheduling (SPS)-Physical Downlink Shared Channel (PDSCH)) to a terminal device, so that the terminal device can receive downlink data on the SPS-PDSCH every other period. The terminal device can also send data to the access network device every other period through semi-statically configured resources, that is, Configured Grant (CG)-Physical Uplink Shared Channel (PUSCH), where the CG-PUSCH is uplink resources configured by the access network device.

[0003] After the SPS-PDSCH is configured or activated, the amount of downlink data sent by the access network device on the SPS-PDSCH and the modulation mode of the transmitted signal are both fixed; similarly, after the CG-PUSCH is configured or activated, the amount of uplink data sent by the terminal device on the CG-PUSCH and the modulation mode of the transmitted signal are also both fixed, which will reduce the flexibility of the communication system.

[0062] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0063] In order to better understand the embodiments of this application, the following introduces the professional terms related to the embodiments of this application:

[0064] Semi-Persistent Scheduling (SPS): It refers to semi-statically configuring radio resources, that is, the access network device can allocate downlink resources (SPS-PDSCH) to the terminal device in a time-slot manner, so that the terminal device can use the SPS-PDSCH to receive downlink data sent by the access network device every other time slot. Among them, the SPS-PDSCH is specified by a Physical Downlink Control Channel (PDCCH) scrambled by a Configured Scheduling (CS)-Radio Network Tempory Identity (RNTI). The SPS-PDSCH can be configured by the terminal device, but after the terminal device configures it successfully, it needs to be activated by the PDCCH scrambled by the CS-RNTI before the terminal device can use the SPS-PDSCH to receive downlink data. Among them, the CS-RNTI is used for semi-persistent scheduling of the downlink or uplink grant configuration. The PDCCH scrambled by the CS-RNTI can be used for the activation and release of the SPS-PDSCH. When the access network device performs semi-persistent scheduling on the terminal device,

[0065] Downlink Control Information (DCI): The downlink control information carried by the downlink physical control channel and sent by the access network device to the terminal device. The DCI may include uplink and downlink resource allocation, HARQ information, power control, etc. When the DCI is used for semi-persistent scheduling of the terminal device, it can be called SPS-DCI. The SPS-DCI is transmitted on the SPS-PDCCH.

[0066] Configured Grant Physical Uplink Shared Channel (CG-PUSCH): This resource is the uplink resource slotally allocated by the access network device to the terminal device. The terminal device can use the CG-PUSCH to send uplink data to the access network device every other time slot. Among them, the CG-PUSCH is the resource allocated by the PDCCH scrambled by the CS-RNTI sent by the access network device or specified by higher-layer signaling.

[0067] Uplink Control Information (UCI): The content included in the UCI information is all information related to the current state of the terminal device. For example, whether the current terminal device needs to request uplink resources, the downlink link quality detected by the current terminal device, the precoding matrix that the terminal device tells the access network device to use, the number of transport layers that the terminal device can distinguish, and whether the terminal device has successfully decoded the PDSCH block, etc. These information cannot be known on the access network device side and can only be reported by the UE. Different from the fact that DCI can only be transmitted in the PDCCH, UCI can be transmitted either in the Physical Uplink Control Channel (PUCCH) or in the PUSCH. When UCI is transmitted in the CG-PUSCH, it can be called CG-UCI. The CG-UCI may include information such as the Hybrid Automatic Repeat reQuest (HARQ) process number, redundancy version (RV), new data indicator (NDI), and channel occupancy time (COT).

[0068] Modulation and Coding Scheme (MCS): The rate configuration in a communication network is achieved through the MCS index value. MCS takes the factors affecting the communication rate of concern as the columns of a table and the MCS index as the rows, forming a rate table. Therefore, each MCS index actually corresponds to the physical transmission rate under a set of parameters.

[0069] To better understand the embodiments of the present application, the network architecture applicable to the embodiments of the present application will be described below.

[0070] Please refer to Figure 1 , Figure 1 which is a schematic diagram of a network architecture for controlling information transmission provided by the embodiments of the present application. As Figure 1 shown, the network architecture for controlling information transmission includes an access network device and a terminal device, and the terminal device establishes a connection with the access network device through a serving cell. Among them, two channels are configured in the serving cell, namely SPS-PDSCH and CG-PUSCH. In practical applications, a serving cell may include more than two channels. The embodiments of the present application take a serving cell including two channels as an example, without limitation. Among them, SPS-PDSCH is a channel through which the access network device intermittently sends data information to the terminal device; CG-PUSCH is a channel through which the terminal device intermittently sends data information to the access network device. The access network device sends SPS-DCI through SPS-PDCCH; and the terminal device sends CG-UCI to the access network device either through CG-PUSCH or through CG-PUCCH. The embodiments of the present application take the terminal device sending CG-UCI through CG-PUSCH as an example.

[0071] It should be noted that SPS-PDSCH is activated by a CS-RNTI scrambled PDCCH sent by the access network device to the terminal device, and CG-PUSCH is allocated by a CS-RNTI scrambled PDCCH or high-layer signaling sent by the access network device to the terminal device.

[0072] The access network device involved in the embodiments of this application is an entity on the network side for transmitting or receiving signals, which can be used to mutually convert received air frames and Internet Protocol (IP) packets, and act as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network, etc. The access network device can also coordinate the attribute management of the air interface. For example, the access network device can be an eNB in LTE, can also be a New Radio Controller (NR controller), can be a gNB in a 5G system, can be a Centralized Unit, can be a new radio base station, can be a remote radio head, can be a micro base station, can be a Relay, can be a Distributed Unit, can be a Transmission Reception Point (TRP) or a Transmission Point (TP), or any other radio access device, but the embodiments of this application are not limited thereto.

[0073] The terminal device involved in the embodiments of this application is an entity on the user side for receiving or transmitting signals. The terminal device can be a device that provides voice and / or data connectivity to users. For example, it can be a handheld device, a vehicle-mounted device, etc. with wireless connection capabilities. The terminal device can also be other processing devices connected to a wireless modem. The terminal device can communicate with a Radio Access Network (RAN). The terminal device can also be referred to as a wireless terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE), etc. The terminal device can be a mobile terminal, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges voice and / or data with the wireless access network. For example, the terminal device can also be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), etc. Common terminal devices include, for example: mobile phones, tablet computers, laptop computers, palm computers, Mobile Internet Devices (MIDs), vehicles, roadside devices, aircraft, wearable devices, such as smart watches, smart bracelets, pedometers, etc., but the embodiments of this application are not limited thereto. The following provides a detailed introduction to the communication method and related devices provided by this application.

[0074] In order to improve the flexibility of the communication system, the embodiments of this application provide a transmission method and device. The following further provides a detailed introduction to the transmission method and device provided by the embodiments of this application.

[0075] Please refer to Figure 2 , Figure 2This application provides a schematic flowchart of a transmission method. The transmission method includes the following operations 210 to 220. Figure 2 The execution subject of the method shown can be a terminal device, or the subject can be a chip in the terminal device. When the terminal device executes the Figure 2 process shown, the following steps can be included:

[0076] 210. The terminal device receives a first message sent by an access network device, and this first message is used to indicate the parameters included in the uplink control information UCI carried on the configured grant - physical uplink shared channel CG - PUSCH.

[0077] Among them, this first message can be a high - layer signaling sent by the access network device to the terminal device. This first message can notify the terminal device of the type of UCI and the parameters included in this UCI. Among them, this UCI can be CG - UCI. This first message can be used to indicate the type of UCI carried on the above - mentioned CG - PUSCH. Among them, the type of UCI corresponds to the parameters included in this UCI. Among them, the UCI can include at least one of the following parameters: the type of UCI, the index of MCS, the first resource indication, and the second resource indication. The first resource indication is used to indicate the ending time unit used for uplink data transmission, and the second resource indication is used to indicate the starting time unit used for uplink data transmission. Among them, the first message can configure the UCI type. There can be multiple UCI Types, and one of them can be the HARQ Number, COT sharing, and RV included in the unlicensed band.

[0078] The above - mentioned time unit can refer to a period of time in the time domain. Among them, in an embodiment of this application, a time unit can include one or more basic time units. Specifically, the communication (such as uplink communication or downlink communication) in an embodiment of this application is in units of time units. Exemplarily, the time unit can be a radio frame, a subframe, a slot, a micro - slot, a mini - slot, or a symbol, etc. The above - mentioned first resource indication can indicate a bias value, and this bias value can be the value by which the ending time unit used for uplink data transmission is offset relative to the starting time unit used for uplink data transmission.

[0079] 220. The terminal device sends UCI to the access network device according to the first message, and this UCI includes parameter values corresponding to the parameters indicated by the first message.

[0080] Optionally, the terminal device may receive high-layer signaling 1 sent by the access network device. The high-layer signaling 1 may indicate a first adjustment range, which refers to multiple adjustment values that the terminal device can adjust for the parameter value of the end time unit used for uplink data transmission (hereinafter referred to as the uplink end time unit), such as 9, 10, 12, 13, etc.

[0081] Optionally, the access network device may send high-layer signaling 2 to the terminal device to indicate the parameter value of the initial uplink end time unit. The high-layer signaling 2 may indicate the parameter value of the initial uplink end time unit. Among them, the parameter value of the initial uplink end time unit is configured by the access network device. The initial uplink end time unit refers to the uplink end time unit in the uplink resources that the access network device recently first allocated to the terminal device. The uplink resources allocated by the access network device to the terminal device are in certain time units in the CG-PUSCH. The uplink end time unit that the access network device recently first allocated to the terminal device may be referred to as the initial uplink end time unit. It should be noted that the parameter value of the initial uplink end time unit may also be indicated by a DCI message sent by the access network device to the terminal device.

[0082] Optionally, the access network device may send high-layer signaling 3 to the terminal device. The high-layer signaling 3 may indicate a second adjustment range, which refers to multiple adjustment values that the index of the uplink MCS in the terminal device can be adjusted, such as 8, 9, 11, 12, etc. Among them, the modulation method or transmission rate used by the terminal device to send uplink data through the CG-PUSCH is determined according to the index of the uplink MCS. The correspondence between the uplink MCS index and the modulation method or transmission rate may form a table, and the terminal device may determine the specific modulation method or transmission rate according to this table. This table may be specified by the communication protocol.

[0083] Optionally, the access network device may send high-layer signaling 4 to the terminal device to indicate the index of the initial uplink MCS. The high-layer signaling 4 may indicate the index of the initial uplink MCS. Among them, the index of the initial uplink MCS is configured by the access network device. The initial uplink MCS refers to the MCS that the access network device recently first configured for the terminal device and that the terminal device should use when sending an uplink transport block. It should be noted that the index of the initial uplink MCS may also be indicated by a DCI message sent by the access network device to the terminal device.

[0084] Optionally, the access network device may also send to the terminal device a high-layer signaling 5 indicating the parameter value of the time unit for sending UCI, that is, the high-layer signaling 5 of the parameter value of the uplink control information transmission time unit. For example, the high-layer signaling 5 may determine that the uplink control information transmission time unit is fixed at a relatively fixed position configured or activated, such as behind a Demodulation Reference Signal (DMRS) symbol. For example, as Figure 3 shown in a schematic diagram of the information transmission situation of each time unit within a time slot, where a time slot may be a period, which means that the terminal device or the access network device periodically transmits data. The terminal device may determine that the uplink control information transmission time unit is after the DMRS symbol according to the first message.

[0085] In a possible implementation manner, the terminal device may determine the parameter value of the uplink end time unit within the first adjustment range. Specifically, before sending UCI to the access network device, the terminal device may determine the number of at least one uplink data transmission time unit for sending the uplink transport block; and determine the parameter values of each uplink data transmission time unit in the at least one uplink data transmission time unit according to the uplink control information transmission time unit. Among them, the number of at least one uplink data transmission time unit determined by the terminal device for sending the uplink transport block may be based on dimensions such as channel state information and the data volume size of the uplink transport block. For example, if the parameter value of the uplink control information transmission time unit is 9 and the number of uplink data transmission time units is 3, then the parameter values of each uplink data transmission time unit in the at least one uplink data transmission time unit are 10, 11, and 12 respectively. Among them, the uplink control information transmission time unit is the time unit for sending UCI, and at least one uplink data transmission time unit is located after and adjacent to the uplink control information transmission time unit. Furthermore, the terminal device may use the parameter value of the uplink data transmission time unit with the largest parameter value among each uplink data transmission time unit in the at least one uplink data transmission time unit as the parameter value of the uplink end time unit.

[0086] Optionally, the uplink content information combination may include the index of the uplink MCS. The terminal device may determine the index of the uplink MCS within the second adjustment range. Specifically, the terminal device may determine the index of the uplink MCS according to the current channel state information. The terminal device may determine the index of the uplink MCS by itself according to the channel state information.

[0087] In a possible implementation, the parameter value of the uplink end time unit determined by the terminal device can be used to indicate the uplink end time unit, and the index of the uplink MCS determined by the terminal device can be used to indicate the uplink MCS. That is to say, after the terminal device determines the parameter value of the uplink end time unit and the index of the uplink MCS, it can choose to directly send the determined parameter value of the uplink end time unit and the index of the uplink MCS to the access network device through CG-UCI.

[0088] Optionally, the parameter value of the uplink end time unit determined by the terminal device is used to indicate the offset value of the index of the uplink end time unit determined by the terminal device from the parameter value of the initial uplink end time unit; the index of the uplink MCS determined by the terminal device is used to indicate the offset value of the index of the uplink MCS determined by the terminal device from the index of the initial uplink MCS. Among them, the parameter value of the initial uplink end time unit and the initial uplink MCS can both be determined by the access network device. In this case, both the parameter value of the uplink end time unit and the index of the uplink MCS can be code points. The code points corresponding to different uplink end time units (hereinafter referred to as the first code points) can indicate the offset value of the parameter value of the uplink end time unit from the parameter value of the initial uplink end time unit, and the code points corresponding to different uplink MCSs (hereinafter referred to as the second code points) can indicate the offset value of the index of the uplink MCS from the index of the initial uplink MCS.

[0089] As Figure 4a shown is a schematic diagram showing the relationship between code points and the index of the end time unit. Among them, the end time unit here can be an uplink end time unit or a downlink end time unit. The downlink end time unit is a time unit that the access network device needs to use when sending downlink data to the terminal device. When the Code point is 00, it can indicate that the end time unit is the initial end time unit; when the Code point is 01, it can indicate that the end time unit is the initial end time unit +1; when the Code point is 10, it can indicate that the end time unit is the initial end time unit -1; when the Code point is 11, it can indicate that the end time unit is the initial end time unit -2. Of course, the value range of the Code point is not limited to these four values. If other values need to be added, corresponding bits can be added for representation.

[0090] As Figure 4bThe figure shows a schematic diagram of the relationship between code points and the indexes of MCS. Herein, the MCS here can be an uplink MCS or a downlink MCS. The downlink MCS is the MCS information that needs to be used when the access network device sends downlink data to the terminal device. When the Code point is 00, it can indicate that the MCS is the index of the initial MCS; when the Code point is 01, it can indicate that the MCS is the index of the initial MCS + 1; when the Code point is 10, it can indicate that the MCS is the index of the initial MCS - 1; when the Code point is 11, it can indicate that the MCS is the index of the initial MCS - 2.

[0091] The following combines Figure 3 to make a detailed description of determining the parameter values of each parameter in UCI. Assume that the parameter value of the uplink end time unit determined by the terminal device in time slot 1 is the same as the parameter value of the initial uplink end time unit, and the index of the uplink MCS determined in time slot 1 is the same as the index of the initial uplink MCS, then there is no need to change these two indexes. Among them, the data transmission symbol refers to the time unit for transmitting uplink data, and the time unit can be a symbol. For example, the parameter value of the initial uplink end time unit is 11, the index of the initial uplink MCS is 10, the parameter value of the uplink end time unit determined by the terminal device in time slot 1 is 11, and the index of the uplink MCS determined by the terminal device in time slot 1 is 10. The terminal device can send these two indexes to the access network device through CG-UCI, or send the first code point corresponding to the uplink end time unit (which should be 00 at this time) and the second code point corresponding to the uplink MCS (which should be 00 at this time) to the access network device. In this way, the access network device can determine according to the tables such as Figure 4a and Figure 4b that neither the parameter value of the received uplink end time unit relative to the parameter value of the initial uplink end time unit nor the index of the uplink MCS relative to the index of the initial uplink MCS has changed. Furthermore, the terminal device can receive the uplink data sent by the terminal device on the time-frequency resource indicated by this CG-UCI.

[0092] If the current time slot is Figure 3 the time slot 2 in, assume that the parameter value of the uplink end time unit determined by the terminal device in time slot 2 is 10, and the index of the uplink MCS is 9. Then the terminal device can directly send the parameter values of the two to the access network device through CG-UCI, or set the first code point to 10, set the second code point to 10, and send the two code points to the access network device through CG-UCI, and so on. For time slot 3 or time slot 4, the principle is the same as above, and no further details are given here.

[0093] After the terminal device determines the parameter value of the uplink end time unit and the index of the uplink MCS in the current time slot, it can send the UCI including the parameter value of the uplink end time unit and the index of the uplink MCS to the access network device, so that the access network device can receive the uplink data (i.e., the uplink transport block) sent by the terminal device according to the time-frequency resources indicated by the UCI.

[0094] Through the embodiments of the present application, the terminal device can determine the parameters that should be included in the UCI after receiving the first message. Among them, the UCI is carried on the CG-PUSCH, and the terminal device can send the UCI to the access network device according to the first message, and the UCI includes the parameter values corresponding to the parameters indicated by the first message. Among them, the terminal device can configure the parameter values corresponding to the parameters indicated by the first message. For example, it can determine the parameter values of the combination unit used for uplink data transmission indicated by the first resource indication in the parameters indicated by the first message, and determine the index of the uplink MCS, and then notify the access network device through the UCI. Through this method, the flexibility of the communication network is improved.

[0095] Please refer to Figure 5 , Figure 5 which is a schematic flowchart of another transmission method provided by the embodiments of the present application. The transmission method includes the following operations 510 to 520. Figure 5 The execution subject of the method shown can be the access network device, or the subject can be a chip in the access network. When the access network device executes the process as Figure 5 shown, the following steps can be included:

[0096] 510. The access network device obtains a first message, which is used to indicate the parameters included in the uplink control information UCI carried on the configured grant-physical uplink shared channel CG-PUSCH.

[0097] Among them, the access network device can be configured to obtain a first message, and acquire this first message. The first message can notify the type of the UCI of the terminal device and the parameters included in the UCI. The first message can be a high-layer signaling. Among them, the UCI can be a CG-UCI. The first message can be used to indicate the type of the UCI carried on the above-mentioned CG-PUSCH, where the type of the UCI corresponds to the parameters included in the UCI. Among them, the UCI can include at least one of the following parameters: the type of the UCI, the index of the MCS, the first resource indication, and the second resource indication. The first resource indication is used to indicate the ending time unit used for uplink data transmission, and the second resource indication is used to indicate the starting time unit used for uplink data transmission. Among them, the first message can configure the UCI type. The UCI can have multiple UCI Types, and one of them can be the HARQ Number, COT sharing, and RV included in the unlicensed band.

[0098] The above time unit can refer to a period of time in the time domain. Among them, in an embodiment of the present application, a time unit can include one or more basic time units. Specifically, the communication (such as uplink communication or downlink communication) in the embodiment of the present application is in units of time units. Exemplarily, the time unit can be a radio frame, a subframe, a slot, a micro-slot, a mini-slot, or a symbol, etc. The above first resource indication can indicate a bias value, and the bias value can refer to the value by which the ending time unit used for uplink data transmission is biased relative to the starting time unit used for uplink data transmission.

[0099] 520. The access network device sends a first message to the terminal device.

[0100] After the access network device sends the first message to the terminal device, the terminal device can determine the parameters included in the UCI according to the first message, and send the UCI to the access network device according to the first message.

[0101] Through this method, the access network device can send a first message to the terminal device, and indicate the parameters included in the uplink control information UCI carried on the CG-PUSCH through this first message. In this way, the terminal device can send a UCI including the parameter values corresponding to the parameters indicated by the first message to the access network device according to the first message, and send the corresponding uplink data through the CG-PUSCH. Through this method, the flexibility of the communication system can be improved.

[0102] Please refer to Figure 6 , Figure 6This is a flowchart showing another transmission method provided by an embodiment of the present application. The transmission method includes the following operations 610 to 620. Figure 6 The execution subject of the method shown can be an access network device, or the subject can be a chip in the access network. When the access network device executes the process as Figure 5 shown, the following steps can be included:

[0103] 610. The access network device obtains a second message, which is used to indicate parameters included in downlink control information (DCI) carried on a semi-persistent scheduling - physical downlink shared channel (SPS-PDSCH).

[0104] Among them, the second message can be a high-layer signaling, which is sent by the access network device to the terminal device. The second message can notify the terminal device of the type of DCI carried on the SPS-PDSCH. The type of DCI corresponds to the parameters included in the DCI. The DCI can be SPS-DCI. The second message can indicate at least one of the following parameters of the DCI: the type of DCI, MCS information, a third resource indication, a fourth resource indication, and uplink HARQ-acknowledgment (ACK). Among them, the third resource indication is used to indicate the end time unit used for downlink data transmission, and the fourth resource indication is used to indicate the start time unit used for downlink data transmission. The second message can also be used to configure the type of DCI.

[0105] 620. The access network device sends a first message to the terminal device.

[0106] Optionally, the access network device can send a high-layer signaling to the terminal device to indicate the initial downlink end time unit, and the high-layer signaling can indicate the parameter value of the initial downlink end time unit. Among them, the initial downlink end time unit can be configured by the access network device. The initial downlink end time unit refers to the downlink end time unit in the downlink resources to be used when the access network device first sends downlink data to the terminal device recently. The downlink resources can be several time units in each time slot of the SPS-PDSCH. It should be noted that the parameter value of the initial uplink end time unit can also be indicated by a DCI message sent by the access network device to the terminal device.

[0107] Optionally, the access network device can send a high-layer signaling to the terminal device to indicate the initial downlink MCS, and the high-layer signaling can indicate the index of the initial MCS. Among them, the initial downlink MCS can be configured by the access network device. The initial downlink MCS refers to the MCS that should be adopted when the access network device first sends a downlink transport block to the terminal device recently. It should be noted that the index of the initial downlink MCS can also be indicated by a DCI message sent by the access network device to the terminal device.

[0108] It should be noted that the access network device sends the SPS-DCI to the terminal device through the SPS-PDCCH. And the access network device sends downlink data (downlink transport block) through the SPS-PDSCH.

[0109] Optionally, the access network device may send to the terminal device a high-layer signaling for indicating the parameter value of the time unit for sending the SPS-DCI, that is, the high-layer signaling of the parameter value of the downlink control information transmission time unit. For example, the access network device may determine that the time unit for sending the uplink control information is fixed at a relatively fixed position in the configuration or activation, such as behind the Demodulation Reference Signal (DMRS) symbol. For example, as Figure 3 shown, the access network device determines that the downlink control information transmission time unit is after the DMRS symbol.

[0110] In a possible implementation manner, the access network device may determine the parameter value of the downlink end time unit within a third adjustment range. Wherein, the third adjustment range may include multiple adjustment values of the parameter value of the downlink end time unit, such as 9, 10, 11, 13, etc. The third adjustment range is determined by the access network device. Specifically, the access network device may determine at least one downlink data transmission unit for sending the downlink transport block. Wherein, the number of at least one downlink data transmission time unit determined by the access network device for sending the downlink transport block may be based on dimensions such as channel state information and the data volume size of the uplink transport block. The access network device determines the parameter value of each downlink data transmission time unit in the at least one downlink data transmission time unit according to the downlink control information transmission time unit. Wherein, the downlink control information transmission time unit is the time unit for sending the DCI, and the at least one downlink data transmission time unit is located after and adjacent to the downlink control information transmission time unit. In this way, the access network device may use the maximum parameter value among the parameter values of the above-mentioned each downlink data transmission time unit as the parameter value of the downlink end time unit.

[0111] Optionally, the access network device may determine the index of the downlink MCS within a fourth adjustment range. Specifically, the access network device may determine the index of the downlink MCS according to the channel state information. Wherein, the fourth adjustment range may include multiple adjustment values of the index of the downlink MCS, such as 8, 9, 11, 12, etc. Wherein, the modulation method or transmission rate used by the access network device to send downlink data through the SPS-PDSCH is determined according to the index of the downlink MCS. The corresponding relationship between the downlink MCS index and the modulation method or transmission rate may form a table, and the terminal device may determine the specific modulation method or transmission rate according to this table, and this table may be specified by the communication protocol.

[0112] In a possible implementation, the parameter value of the downlink end time unit determined by the access network device can be used to indicate the downlink end time unit, and the index of the downlink MCS determined by the access network device can be used to indicate the downlink MCS in the current time slot. That is to say, after the terminal device determines the parameter value of the downlink end time unit and the index of the downlink MCS, it can directly send the determined parameter value of the downlink end time unit and the index of the downlink MCS to the terminal device through the SPS-DCI.

[0113] Optionally, the parameter value of the downlink end time unit determined by the access network device is used to indicate the offset value of the parameter value of the downlink end time unit determined by the access network device from the parameter value of the initial downlink end time unit; the index of the downlink MCS determined by the access network device is used to indicate the offset value of the index of the downlink MCS determined by the access network device in the current time slot from the index of the initial downlink MCS. Among them, the parameter value of the initial downlink end time unit and the initial downlink MCS can both be determined by the access network device. If the index indicates an offset value, the index can be a code point. Different code points corresponding to different downlink end time units (hereinafter referred to as the third code point) can indicate the offset value of the parameter value of the downlink end time unit from the parameter value of the initial downlink end time unit, and different code points corresponding to different downlink MCSs (hereinafter referred to as the fourth code point) can indicate the offset value of the index of the downlink MCS from the index of the initial downlink MCS. The relationship between the third code point and the parameter value of the downlink end time unit is as Figure 4a shown, and the relationship between the fourth code point and the index of the downlink MCS is as Figure 4b shown. Since both have been described above, they will not be elaborated here.

[0114] The following will describe in detail the situation of the access network device determining the parameters in the DCI in combination with Figure 3 Suppose the parameter value of the initial downlink end time unit determined by the access network device is 11, and the index of the initial downlink MCS is 10, and they have been notified to the terminal device through the corresponding higher-layer information. It is also assumed that the current time slot is Figure 3 slot 3 in, then the access network device can determine that the parameter value of the downlink end time unit is 12, and it is assumed that the index of the downlink MCS determined by the access network device in the current time slot is 10. Then the access network device can directly tell the terminal device the parameter value of the downlink end time unit and the index of the downlink MCS through the SPS-DCI. Or the access network device can also set the third code point to 01 (i.e., the initial downlink end time unit + 1) and the fourth code point to 00 (i.e., the initial downlink MCS), and send the third code point and the fourth code point to the terminal device through the SPS-DCI.

[0115] For another example, the current time slot isFigure 3 When in time slot 4, the access network device can determine that the parameter value of the downlink end time unit is 13, and assume that the index of the downlink MCS determined by the access network device in the current time slot is 9. Then the access network device can directly tell the terminal device the parameter value of the downlink end time unit and the index of the downlink MCS through the SPS-DCI. Or the access network device can also set the third code point to 11 (i.e., the initial downlink end time unit + 2) and the fourth code point to 10 (i.e., the initial downlink MCS - 1), and send the third code point and the fourth code point to the terminal device through the SPS-DCI.

[0116] After the access network device determines the parameter value of the downlink end time unit and the index of the downlink MCS in the current time slot, it can send the SPS-DCI including the parameter value of the downlink end time unit and the index of the downlink MCS to the terminal device, so that the terminal device can receive the downlink data (i.e., the downlink transport block) sent by the access network device according to the time-frequency resources indicated by the SPS-DCI in the current time slot.

[0117] Through the embodiments of the present application, the access network device can notify the terminal device of the parameters included in the DCI through the second message. When the access network device needs to send downlink data to the terminal device, it can determine the parameter values of each parameter in the DCI and notify the terminal device through the DCI. In this way, the terminal device can determine the parameter values of each parameter determined by the access network device according to the DCI, and receive the downlink data sent by the access network device according to these parameter values. Through this method, the flexibility of the communication network can be improved.

[0118] Please refer to Figure 7 , Figure 7 which is a schematic flowchart of another transmission method provided by the embodiments of the present application. The transmission method includes the following operations 710 to 720.

[0119] 710. The terminal device receives a second message sent by the access network device, and the second message is used to indicate the parameters included in the downlink control information DCI carried on the semi-static scheduling - physical downlink shared channel SPS-PDSCH;

[0120] Among them, the second message may be a high-layer signaling sent by an access network device to a terminal device. The second message may notify the terminal device of the type of DCI carried on the SPS-PDSCH. The type of the DCI corresponds to the parameters included in the DCI. The DCI may be an SPS-DCI. The second message may indicate at least one of the following parameters included in the DCI: the type of the DCI, MCS information, a third resource indication, a fourth resource indication, and uplink HARQ-acknowledgment (ACK). Among them, the third resource indication is used to indicate the end time unit used for downlink data transmission, and the fourth resource indication is used to indicate the start time unit used for downlink data transmission. The second message may also be used to configure the type of the DCI.

[0121] 720. The terminal device determines, according to the second message, that the DCI includes parameter values corresponding to the parameters indicated by the second message.

[0122] Through this method, the terminal device can determine the parameters included in the DCI according to the second message sent by the access network device. When the terminal device receives the DCI sent by the access network device, it can determine the parameter values included in the DCI that correspond to the parameters indicated by the second message. In this way, the terminal device can receive the downlink data sent by the access network device according to the DCI. Through this method, the flexibility of the communication system can be improved.
