Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

In order to better understand the embodiments of the present application, the following terms refer to the embodiments of the present application:

Semi-Persistent Scheduling (SPS): the radio resources are configured semi-statically, that is, the access network device may allocate downlink resources (SPS-PDSCH) to the terminal device in a time slot manner, so that the terminal device may receive downlink data sent by the access network device using the SPS-PDSCH every time slot. The SPS-PDSCH is specified by a Physical Downlink Control Channel (PDCCH) scrambled by a Configured Scheduling (CS) -Radio Network Temporary Identity (RNTI) sent by the access Network device. The SPS-PDSCH can be configured by the terminal equipment, but after the terminal equipment is successfully configured, the terminal equipment can use the SPS-PDSCH to receive downlink data after the terminal equipment needs to be activated through a PDCCH scrambled by a CS-RNTI. The CS-RNTI is used for the configuration of semi-persistent scheduling or uplink authorization of a downlink. The CS-RNTI scrambled PDCCH can be used for activation and release of the SPS-PDSCH. The access network device performs semi-persistent scheduling on the terminal device, then,

downlink Control Information (DCI): the downlink physical control channel carries the downlink control information, which is sent to the terminal device by the access network device, and the DCI may include uplink and downlink resource allocation, HARQ information, power control, and the like. When the DCI is used for semi-persistent scheduling for the terminal device, it may be referred to as SPS-DCI. The SPS-DCI is transmitted on the SPS-PDCCH.

Configuring a licensed Physical Uplink Shared Channel (CG-PUSCH): the resource is uplink resource which is allocated to the terminal device by the access network device in a time slot manner, and the terminal device can use the CG-PUSCH to send uplink data to the access network device every time slot. The CG-PUSCH is a resource which is assigned by a PDCCH scrambled by a CS-RNTI sent by the access network equipment or a higher layer signaling.

Uplink Control Information (UCI): the UCI information includes information related to the current terminal device status, such as whether the current terminal device needs to request uplink resources, the downlink quality detected by the current terminal device, the precoding matrix that the terminal device tells the access network device should use, the number of transmission layers that the terminal device can distinguish, and whether the terminal device successfully decodes the PDSCH block, and the like, which cannot be known by the access network device side and can only be reported by the UE. Unlike DCI which can only be transmitted in PDCCH, UCI may be transmitted in Physical Uplink Control Channel (PUCCH) or PUSCH. When UCI is transmitted in CG-PUSCH, it may be referred to as CG-UCI. The CG-UCI may include information such as a Hybrid Automatic Repeat reQuest (HARQ) Process Number (Process Number), a Redundancy Version (RV), a New Data Indicator (NDI), a Channel Occupancy Time (COT), and the like.

Modulation and Coding Scheme (MCS): the rate configuration in the communication network is realized by the MCS index value. The MCS forms a rate table with the MCS index as a row and the columns of the table as the factors that affect the communication rate concerned. Therefore, each MCS index actually corresponds to a physical transmission rate under a set of parameters.

In order to better understand the embodiments of the present application, a network architecture to which the embodiments of the present application are applicable is described below.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture for controlling information transmission according to an embodiment of the present disclosure. As shown in fig. 1, the network architecture for controlling information transmission includes an access network device and a terminal device, where the terminal device establishes a connection with the access network device through a serving cell. Wherein, two channels, namely SPS-PDSCH and CG-PUSCH, are configured in the serving cell. In practical applications, one serving cell may include more than two channels, and in the embodiment of the present application, the serving cell includes two channels as an example, which is not limited. The SPS-PDSCH is a channel for transmitting data information to the terminal equipment by the access network equipment in a time slot manner; CG-PUSCH is a channel in which a terminal device transmits data information to an access network device in a time-slotted manner. The access network equipment sends SPS-DCI to the terminal equipment through the SPS-PDCCH; the CG-UCI sent by the terminal device to the access network device may be sent through a CG-PUSCH or through a CG-PUCCH, and in the embodiment of the present application, the CG-UCI sent by the terminal device through a CG-PUSCH is taken as an example.

The SPS-PDSCH is activated by a PDCCH scrambled by a CS-RNTI sent by the access network equipment to the terminal equipment, and the CG-PUSCH is allocated by the PDCCH scrambled by the CS-RNTI sent by the access network equipment to the terminal equipment or a higher layer signaling.

The access network device in the embodiment of the present application is an entity for transmitting or receiving a signal on a network side, and may be configured to perform inter-conversion between a received air frame and an Internet Protocol (IP) packet, and serve as a router between a terminal device and the rest of the access network, where the rest of the access network may include an IP network and the like.

The terminal device referred to in the embodiments of the present application is an entity for receiving or transmitting signals at a user side. The terminal device may be a device providing voice and/or data connectivity to a user, e.g. a handheld device, a vehicle mounted device, etc. with wireless connection capability.

The terminal equipment may be mobile terminals such as mobile telephones (or so-called "cellular" telephones) and computers having mobile terminals, e.g. mobile devices which may be portable, pocket, hand-held, computer-included or vehicle-mounted, which exchange language and/or data with a radio access network. For example, the terminal device may 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), or the like. Common terminal devices include, for example: the Mobile terminal may be a Mobile phone, a tablet computer, a laptop computer, a palmtop computer, a Mobile Internet Device (MID), a vehicle, a roadside Device, an aircraft, a wearable Device, such as a smart watch, a smart bracelet, a pedometer, or the like, but the embodiment of the present application is not limited thereto. The communication method and the related device provided by the present application are described in detail below.

In order to improve the flexibility of the communication system, embodiments of the present application provide a transmission method and apparatus, and the transmission method and apparatus provided in the embodiments of the present application are further described in detail below.

Referring to fig. 2, fig. 2 is a schematic flow chart of a transmission method according to an embodiment of the present disclosure. The transmission method includes operations 210 to 220 as follows. The main body for executing the method shown in fig. 2 may be the terminal device, or the main body may be a chip in the terminal device. When the terminal device executes the flow shown in fig. 2, the following steps may be included:

210. the terminal equipment receives a first message sent by the access network equipment, wherein the first message is used for indicating parameters contained in uplink control information UCI carried on a configuration grant-physical uplink shared channel CG-PUSCH.

The first message may be a higher layer signaling sent by the access network device to the terminal device, and the first message may notify the terminal device of the type of UCI, and the UCI includes parameters. Wherein the UCI may be CG-UCI. The first message may be used to indicate a type of UCI carrying on the CG-PUSCH, where the type of UCI corresponds to a parameter included in the UCI. Wherein, the UCI may 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 for indicating an end time unit used for uplink data transmission, and the second resource indication is used for indicating a start time unit used for uplink data transmission. The first message may configure a UCI Type, the UCI may have multiple UCI types (types), and one of the UCI types may be HARQ Number, COT sharing, and RV included in an Unlicensed Band (Unlicensed Band).

The time unit may refer to a period of time in the time domain. In the embodiment of the present application, a time unit may 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. For example, the time unit may be a radio frame (radio frame), a subframe (subframe), a slot (slot), a micro-slot (micro-slot), a mini-slot (mini-slot), or a symbol. The first resource indication may indicate an offset value, and the offset value may be a value offset from a start time unit used for uplink data transmission by an end time unit used for uplink data transmission.

220. And the terminal equipment sends UCI to the access network equipment according to the first message, wherein the UCI comprises a parameter value corresponding to the parameter indicated by the first message.

Optionally, the terminal device may receive a higher layer signaling 1 sent by the access network device, where the higher layer signaling 1 may indicate a first adjustment range, and the first adjustment range refers to multiple adjustment values, which may be, for example, 9, 10, 12, and 13, and the multiple adjustment values may be used by the terminal device to adjust a parameter value of an end time unit (hereinafter, referred to as an uplink end time unit) used for uplink data transmission.

Optionally, the access network device may send a higher layer signaling 2 indicating a parameter value of the initial uplink end time unit to the terminal device, where the higher layer signaling 2 may indicate the parameter value of the initial uplink end time unit. Wherein, the parameter value of the initial uplink end time unit is configured by the access network equipment. The initial uplink end time unit refers to an uplink end time unit in uplink resources which are allocated to the terminal device by the access network device for the first time recently. The uplink resource allocated to the terminal device by the access network device is in a certain time unit in CG-PUSCH. The uplink end time unit that the access network device has most recently allocated to the terminal device for the first time may be referred to as an 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.

Optionally, the access network device may send a higher layer signaling 3 to the terminal device, where the higher layer signaling 3 may indicate a second adjustment range, and the second adjustment range refers to multiple adjustment values that an index of an uplink MCS in the terminal device may adjust, and may be, for example, 8, 9, 11, 12, and the like. The modulation method or the transmission rate adopted when the terminal equipment transmits the uplink data through the CG-PUSCH is determined according to the index of the uplink MCS. The corresponding relationship between the uplink MCS index and the modulation scheme or the transmission rate may form a table, and the terminal device may determine a specific modulation scheme or transmission rate according to the table, where the table may be specified by a communication protocol.

Optionally, the access network device may send, to the terminal device, a higher layer signaling 4 indicating an index of the initial uplink MCS, where the higher layer signaling 4 may indicate the index of the initial uplink MCS. Wherein, the index of the initial uplink MCS is the access network equipment configuration. The initial uplink MCS refers to an MCS that the access network device should adopt when transmitting an uplink transport block, and the MCS is newly configured for the terminal device by the access network device for the first time. 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.

Optionally, the access network device may further send a higher layer signaling 5 indicating a parameter value of a time unit for sending the UCI to the terminal device, that is, the higher layer signaling 5 indicating the parameter value of the uplink control information sending time unit. For example, the higher layer signaling 5 may determine that the uplink control information transmission time unit is fixed at a configured or activated relatively fixed position, such as after a Demodulation Reference Signal (DMRS) symbol. For example, as shown in fig. 3, a schematic diagram of a situation where information is transmitted in each time unit in a time slot, where a time slot may be a cycle, and refers to that a terminal device or an access network device periodically transmits data. The terminal device may determine that the uplink control information transmission time element is after the DMRS symbol according to the first message.

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 sending time unit for sending the uplink transport block; and determining the parameter value 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. The number of the at least one uplink data transmission time unit for transmitting the uplink transport block, which is determined by the terminal device, may be based on dimensions such as channel state information, and a data 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 the uplink data transmission time units is 3, the parameter values of each uplink data transmission time unit in at least one uplink data transmission time unit are 10, 11, and 12, respectively. The uplink control information transmission time unit is a time unit for transmitting UCI, and at least one uplink data transmission time unit is located after and adjacent to the uplink control information transmission time unit. And the terminal device may further use a parameter value of an uplink data transmission time unit with a largest parameter value in each uplink data transmission time unit of the at least one uplink data transmission time unit as the parameter value of the uplink end time unit.

Optionally, the uplink content information combination may include an 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 decide the index of the uplink MCS according to the channel state information.

In a possible implementation manner, the parameter value of the uplink end time unit determined by the terminal device may be used to indicate the uplink end time unit, and the index of the uplink MCS determined by the terminal device may be used to indicate the uplink MCS. That is, after determining the parameter value of the uplink end time unit and the index of the uplink MCS, the terminal device may select 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 the CG-UCI.

Optionally, the parameter value of the uplink end time unit determined by the terminal device is used to indicate an offset value between the index of the uplink end time unit determined by the terminal device and the parameter value of the initial uplink end time unit; the index of the uplink MCS determined by the terminal equipment is used for indicating the offset value of the index of the uplink MCS determined by the terminal equipment and the index of the initial uplink MCS. The parameter value of the initial uplink end time unit and the initial uplink MCS may 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 may be a Code Point (Code Point). A code point corresponding to a different uplink end time unit (hereinafter, referred to as a first code point) may indicate an offset value of a parameter value of the uplink end time unit from a parameter value of the initial uplink end time unit, and a code point corresponding to a different uplink MCS (hereinafter, referred to as a second code point) may indicate an offset value of an index of the uplink MCS from an index of the initial uplink MCS.

Fig. 4a shows an intention of expressing a relationship between a code point and an index of an end time unit. Here, the end time unit may be an uplink end time unit or a downlink end time unit. The downlink end time unit is a time unit that needs to be used when the access network device sends downlink data to the terminal device. When Code point is 00, the end time unit can be indicated as an initial end time unit; when Code point is 01, the end time unit can be indicated as initial end time unit + 1; when Code point is 10, it can indicate that the end time unit is initial end time unit-1; when Code point is 11, the end time unit may be indicated as initial end time unit-2. Certainly, the value of the Code point may not be limited to the four values, and if other values need to be added, bits may be added correspondingly to represent the Code point.

Fig. 4b shows an intention of a relationship between code points and MCS indexes. Here, the MCS may be an uplink MCS or a downlink MCS. The downlink MCS is MCS information that needs to be used when the access network device sends downlink data to the terminal device. When Code point is 00, MCS may be indicated as an index of the initial MCS; when Code point is 01, MCS may be indicated as index +1 of initial MCS; when Code point is 10, MCS can be indicated as index-1 of the initial MCS; when Code point is 11, it may indicate that the MCS is index-2 of the initial MCS.

The determination of the parameter values for each parameter in the UCI is described in detail below in conjunction with fig. 3. If the parameter value of the uplink ending time unit determined by the terminal device in the time slot 1 is consistent with the parameter value of the initial uplink ending time unit, and the index of the uplink MCS determined in the time slot 1 is consistent with the index of the initial uplink MCS, the two indexes do not need to be changed. The data transmission symbol refers to a time unit for transmitting uplink data, and the time unit may 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 the slot 1 is 11, and the index of the uplink MCS determined by the terminal device in the slot 1 is 10. The terminal device may send the two indexes to the access network device through CG-UCI, or send a first code point (which should be 00) corresponding to the uplink end time unit and a second code point (which should be 00) corresponding to the uplink MCS to the access network device. In this way, the access network device may determine, according to the tables shown in fig. 4a and fig. 4b, that neither the received parameter value of the 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. And the terminal equipment can receive the uplink data sent by the terminal equipment on the time-frequency resource indicated by the CG-UCI.

If the current time slot is time slot 2 in fig. 3, it is assumed 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, the terminal device may directly send the parameter values of the two to the access network device through the CG-UCI, or may set the first code point to 10, set the second code point to 10, send the two code points to the access network device through the CG-UCI, and so on. The same principle as described above is applied to the time slot 3 or the time slot 4, and the description thereof is omitted here.

After the terminal equipment determines the parameter value of the uplink end time unit and the index of the uplink MCS in the current time slot, the terminal equipment may send UCI including the parameter value of the uplink end time unit and the index of the uplink MCS to the access network equipment, so that the access network equipment may receive uplink data (i.e., an uplink transport block) sent by the terminal equipment according to the time-frequency resource indicated by the UCI.

Through the embodiment of the application, the terminal equipment can determine the parameters which should be included in the UCI after receiving the first message. The UCI is borne on the CG-PUSCH, and the terminal device may send the UCI to the access network device according to the first message, where the UCI includes a parameter value corresponding to the parameter indicated by the first message. The terminal device may configure a parameter value corresponding to the parameter indicated by the first message, for example, may determine a parameter value of a combination unit used for uplink data transmission and indicated by the first resource indication in the parameter indicated by the first message, and determine an index of the uplink MCS, and further notify the access network device through the UCI. By the method, the flexibility of the communication network is improved.

Referring to fig. 5, fig. 5 is a schematic flow chart of another transmission method according to the embodiment of the present application. The transmission method includes operations 510 to 520 as follows. The method execution body shown in fig. 5 may be an access network device, or the body may be a chip in an access network. When the access network device performs the procedure shown in fig. 5, the following steps may be included:

510. the access network equipment acquires a first message, wherein the first message is used for indicating parameters contained in uplink control information UCI carried on a configuration authorization-physical uplink shared channel CG-PUSCH.

The access network device may configure to obtain a first message, and acquire the first message, where the first message may notify a terminal device of a type of UCI, and the UCI includes a parameter, and the first message may be a higher layer signaling.

Referring to fig. 6, fig. 6 is a schematic flow chart of another transmission method according to the embodiment of the present application. The transmission method includes operations 610 through 620 as follows. The method execution body shown in fig. 6 may be an access network device, or the body may be a chip in the access network. When the access network device performs the procedure shown in fig. 5, the following steps may be included:

610. the access network equipment acquires a second message, wherein the second message is used for indicating parameters included in downlink control information DCI carried on a semi-persistent scheduling-physical downlink shared channel (SPS-PDSCH).

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

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

Optionally, the access network device may send, to the terminal device, a higher layer signaling for indicating the initial downlink end time unit, where the higher layer signaling may indicate a parameter value of the initial downlink end time unit. Wherein, the initial downlink end time unit may be configured by the access network device. The initial downlink end time unit refers to a downlink end time unit in downlink resources to be used when the access network device sends downlink data to the terminal device for the first time recently. The downlink resource may be some number of time units of each slot in the SPS-PDSCH. 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.

Optionally, the access network device may send, to the terminal device, a higher layer signaling for indicating the initial downlink MCS, where the higher layer signaling may indicate an index of the initial MCS. Wherein the initial downlink MCS may be configured by the access network device. The initial downlink MCS refers to an MCS that the access network device should adopt when transmitting a downlink transport block to the terminal device for the first time recently. It should be noted that the index of the initial downlink MCS may also be indicated by a DCI message sent by the access network device to the terminal device.

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

Optionally, the access network device may send, to the terminal device, a higher layer signaling for indicating a parameter value of a time unit for sending the SPS-DCI, that is, a higher layer signaling for indicating a parameter value of a downlink control information sending time unit. For example, the access network device may determine that the uplink control information transmission time unit is fixed at a configured or activated relatively fixed position, such as after a Demodulation Reference Signal (DMRS) symbol. For example, as in fig. 3, the access network device determines that the downlink control information transmission time element is after the DMRS symbol.

In a possible implementation manner, the access network device may determine the parameter value of the downlink end time unit within the third adjustment range. The third adjustment range may include a plurality of adjustment values, such as 9, 10, 11, and 13, of the parameter value of the downlink end time unit. 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 that transmits the downlink transport block. The access network device determines the number of at least one downlink data transmission time unit for transmitting the downlink transport block based on the channel state information, the data size of the uplink transport block, and other dimensions. The access network equipment determines the parameter value of each downlink data sending time unit in at least one downlink data sending time unit according to the downlink control information sending time unit. The downlink control information sending time unit is a time unit for sending DCI, and at least one downlink data sending time unit is located after the downlink control information sending time unit and adjacent to the downlink control information sending time unit. In this way, the access network device may use the maximum parameter value among the parameter values of the downlink data transmission time units as the parameter value of the downlink end time unit.

Optionally, the access network device may determine the index of the downlink MCS within the fourth adjustment range. Specifically, the access network device may determine an index of the downlink MCS according to the channel state information. Wherein, the fourth adjustment range may include a plurality of adjustment values, such as 8, 9, 11, 12, etc., of the index of the downlink MCS. The modulation mode or the transmission rate adopted when the access network equipment transmits the 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 scheme or the transmission rate may form a table, and the terminal device may determine a specific modulation scheme or transmission rate according to the table, where the table may be specified by a communication protocol.

In a possible implementation manner, a parameter value of the downlink ending time unit determined by the access network device may be used to indicate the downlink ending time unit, and an index of the downlink MCS determined by the access network device may be used to indicate the downlink MCS in the current time slot. That is to say, after determining the parameter value of the downlink ending time unit and the index of the downlink MCS, the terminal device may select to directly transmit the determined parameter value of the downlink ending time unit and the index of the downlink MCS to the terminal device through the SPS-DCI.

Optionally, the parameter value of the downlink ending time unit determined by the access network device is used to indicate an offset value between the parameter value of the downlink ending time unit determined by the access network device and the parameter value of the initial downlink ending time unit; the index of the downlink MCS determined by the access network equipment is used for indicating an offset value between the index of the downlink MCS determined by the access network equipment in the current time slot and the index of the initial downlink MCS. Wherein, both the parameter value of the initial downlink end time unit and the initial downlink MCS may be determined by the access network device. If the index indicates an offset value, the index may be a Code Point (Code Point). A code point (hereinafter, referred to as a third code point) corresponding to a different downlink end time unit may indicate an offset value of a parameter value of the downlink end time unit from a parameter value of the initial downlink end time unit, and a code point (hereinafter, referred to as a fourth code point) corresponding to a different downlink MCS may indicate an offset value of an index of the downlink MCS from an index of the initial downlink MCS. The relationship between the third code point and the parameter value of the downlink ending time unit is shown in fig. 4a, and the relationship between the fourth code point and the index of the downlink MCS is shown in fig. 4b, which are already described above, and therefore, the description thereof is omitted here.

The following describes the determination of the parameter in the DCI by the access network device in detail with reference to fig. 3. It is assumed that the access network device determines that the parameter value of the initial downlink ending time unit is 11, the index of the initial downlink MCS is 10, and the terminal device has been notified through corresponding higher layer information. Assuming that the current time slot is time slot 3 in fig. 3, the access network device may determine that the parameter value of the downlink end time unit is 12, and assume that the index of the downlink MCS determined by the access network device in the current time slot is 10. The access network device can directly inform the terminal device of the parameter value of the downlink ending time unit and the index of the downlink MCS through the SPS-DCI. Or the access network device may set the third code point to 01 (i.e., initial downlink end time unit +1) and the fourth code point to 00 (i.e., initial downlink MCS), and send the third code point and the fourth code point to the terminal device through SPS-DCI.

For another example, when the current time slot is time slot 4 in fig. 3, the access network device may 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. The access network device can directly inform the terminal device of the parameter value of the downlink ending time unit and the index of the downlink MCS through the SPS-DCI. Or the access network device may set the third code point to be 11 (i.e. initial downlink end time unit +2) and the fourth code point to be 10 (i.e. initial downlink MCS-1), and send the third code point and the fourth code point to the terminal device through SPS-DCI.

After determining the parameter value of the downlink ending time unit and the index of the downlink MCS at the current time slot, the access network device may send SPS-DCI including the parameter value of the downlink ending time unit and the index of the downlink MCS to the terminal device, so that the terminal device may receive downlink data (i.e., a downlink transport block) sent by the access network device according to the time-frequency resource indicated by the SPS-DCI at the current time slot.

Through the embodiment of the application, the access network device may notify the terminal device of the parameter included in the DCI through the second message. When the access network device needs to send downlink data to the terminal device, the parameter values of the parameters in the DCI can be determined, and the DCI is notified to the terminal device. Therefore, the terminal equipment can determine the parameter values of each parameter determined by the access network equipment according to the DCI, and receive the downlink data sent by the access network equipment according to the parameter values. The flexibility of the communication network can be improved by the method.

Referring to fig. 7, fig. 7 is a flowchart illustrating another transmission method according to an embodiment of the present application. The transmission method includes operations 710 through 720 as follows. The main body for executing the method shown in fig. 7 may be a terminal device, or the main body may be a chip in the terminal device. When the terminal device executes the flow shown in fig. 5, the following steps may be included:

710. the terminal equipment receives a second message sent by the access network equipment, wherein the second message is used for indicating parameters contained in Downlink Control Information (DCI) borne on a semi-persistent scheduling-physical downlink shared channel (SPS-PDSCH);

720. And the terminal equipment determines that the DCI comprises parameter values corresponding to the parameters indicated by the second message according to the second message.

By the method, the terminal equipment can determine the parameters included in the DCI according to the second message sent by the access network equipment, and after the terminal equipment receives the DCI sent by the access network equipment, the parameter values corresponding to the parameters indicated by the second message and included in the DCI can be determined. In this way, the terminal device may receive the downlink data sent by the access network device according to the DCI. By the method, the flexibility of the communication system can be improved.
