[0044] It should be understood that the embodiments of the present application are only exemplarily described with respect to the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as a Long Term Evolution (LTE) system, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunication System (UMTS), an Internet of Things (IoT) system, a Narrow Band Internet of Things (NB-IoT) system, an enhanced Machine-Type Communications (eMTC) system, a 5G communication system (also referred to as a New Radio (NR) communication system), or a future communication system, etc.

[0045] In the communication system 100 shown in FIG. 1, the network device 120 can be a Radio Access Network (RAN) device that communicates with the terminal device 110. The network device 120 can provide communication coverage for a specific geographic area, and can communicate with the terminal device 110 (e.g., a UE) located in the coverage area.

[0046] The network device 120 can be an Evolutional Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0047] The terminal device 110 can be any terminal device, including but not limited to a terminal device that uses a wired or wireless connection with the network device 120 or other terminal devices.

[0049] FIG. 1 exemplarily shows one network device and two terminal devices. Optionally, the wireless communication system 100 can include multiple network devices, and each network device can include other numbers of terminal devices within its coverage range. The embodiments of the present application do not limit this.

[0050] To facilitate understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any manner, and all of them belong to the protection scope of the embodiments of the present application.

[0051] In a communication system, a terminal device receives downlink control signaling (DCI) transmitted by a network device (e.g., a base station). The signaling includes various transmission parameters required for transmitting uplink transmission or receiving downlink transmission. The terminal device transmits uplink transmission or receives downlink transmission after interpreting various parameters.

[0052] It should be understood that the design of DCI needs to comprehensively consider the scheduling performance and the DCI transmission performance. Specifically, the more fine-grained scheduling information carried in the DCI, the better the corresponding communication performance (efficiency, reliability, etc.), but the DCI overhead will increase accordingly. The increase of DCI overhead will lead to a series of problems such as DCI detection performance degradation, terminal device power consumption increase, terminal device processing delay increase, etc.

[0053] It should also be understood that the frequency domain resource indication is optimal in transmission efficiency if it can indicate any resource block (RB), but the DCI overhead is large at this time. For example, if 240 RBs are included in the bandwidth part (BWP), a bitmap method is used to indicate the frequency domain resource, 240 bits are required, and the DCI overhead is large.

[0054] Based on this, the frequency domain scheduling indication (FDRA) of the LTE and NR system design does not use the bitmap method, but uses an indication method that introduces certain scheduling restrictions. For example, the DCI usually uses a continuous resource indication method, such as a start and length indicator value (SLIV) based indication method or a resource block group (RBG) based indication method.

[0055] Table 1 gives the information field contained in the NR DCI format 1_1 and the corresponding bit number.

[0056] Table 1

[0057] As can be seen from the content in Table 1 above, the DCI carries a large amount of information. How to reduce the actual transmission information amount of the DCI and improve the scheduling performance of the DCI is a problem to be solved.

[0058] Based on this, the embodiment of the present application provides a transmission parameter determination method, wherein the network device can not transmit the actual transmission parameter of the first channel or signal, but send the first information obtained based on the second model processing. In this way, the terminal device can restore the actual transmission parameter of the first channel or signal based on the first information and the first model. It can be understood that the bit number of the first information transmitted between the network device and the terminal device is significantly smaller than the bit number of the original transmission, which reduces the actual transmission information amount to a certain extent. In addition, the network device can also process the more fine transmission parameter through the second model to obtain the first information, thereby realizing more fine scheduling. That is, the transmission parameter determination method provided by the embodiment of the present application can realize more fine scheduling and / or reduce the actual transmission information amount, thereby improving the system efficiency.

[0059] For the convenience of understanding the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined with the technical solutions of the embodiments of the present application in any way as optional solutions, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0060] It should be noted that the uplink channel or signal mentioned in the embodiments of the present application can be understood as uplink transmission, and the two are equivalent or replaceable. In addition, the downlink channel or signal mentioned in the embodiments of the present application can be understood as downlink transmission, and the two are equivalent or replaceable.

[0065] It should be noted that the method provided by the embodiments of the present application can be implemented based on artificial intelligence (AI) / machine learning (ML) technology. The first model and the second model can be AI / ML models.

[0066] FIG. 3 shows a network architecture for obtaining transmission parameters based on AI / ML technology, which is applicable to the embodiments of the present application. Specifically, the network device and the terminal device are both deployed with AI / ML models, wherein the network device side is deployed with an encoding model (which is denoted as a second model in the embodiments of the present application), and the terminal device side can be deployed with a decoding model (which is denoted as a first model in the embodiments of the present application).

[0067] In the embodiments of the present application, the network device can process the transmission parameter of the first channel or signal into the first information by using the second model, and transmit the first information to the terminal device through the downlink. After receiving the first information, the terminal device can restore the actual transmission parameter of the first channel or signal by using the first model corresponding to the second model.

[0068] It should be understood that the first information obtained by the second model can be meaningless bit information.

[0069] It should also be understood that the number of bits of the first information is significantly smaller than the number of bits of the actual transmission parameter directly transmitted.

[0070] It should be noted that the first information can be transmitted through a physical downlink control channel (PDCCH).

[0071] In some embodiments, the first channel or signal can include an uplink channel or signal, and / or a downlink channel or signal. Exemplarily, the first channel or signal can include one or more of the following, but is not limited to:

In the embodiments of the present application, the transmission parameter can also be understood as the scheduling information, unless otherwise specified, the two are equivalent or replaceable.

[0078] It should be noted that the first model and / or the second model can be trained through the processes of construction, training, verification and testing of the data set.

[0079] It should also be noted that the first model and the second model are deployed in pairs on the terminal device and the network device side, and have a corresponding relationship, so the first model and the second model need to be trained together. The first model and the second model can be trained in advance through offline training and / or online training.

[0080] It should be understood that, by the method provided in the embodiments of the present application, the network device can not necessarily transmit the actual transmission parameters of the first channel or signal, but send the first information processed based on the second model, so that the terminal device can restore the actual transmission parameters of the first channel or signal based on the first information and the first model. It can be understood that the number of bits of the first information transmitted between the network device and the terminal device is significantly less than the number of bits of the original transmission, which reduces the amount of information actually transmitted to a certain extent. In addition, the network device can also process more refined transmission parameters through the second model to obtain the first information, so as to realize more refined scheduling. That is, the transmission parameter determination method provided in the embodiments of the present application can realize more refined scheduling and / or reduce the amount of information actually transmitted, thereby improving the system efficiency.

[0081] It should be noted that the manner in which the terminal device determines the first transmission parameters of the first channel or signal based on the first information and the first model can also include multiple manners.

[0119] It should also be noted that, on the basis of acquiring the first transmission parameter by using the method #A, the method provided by the embodiments of the present application can further include the following steps with reference to Fig. 4:

[0120] S240a, the network device sends or receives the first channel or signal according to the first transmission parameter, and correspondingly, the terminal device receives or sends the first channel or signal according to the first transmission parameter output by the first model.

[0121] In the downlink transmission scenario, the network device can transmit the first channel or signal according to the first transmission parameter, and correspondingly, the terminal device can receive the first channel or signal based on the first transmission parameter, for example, the terminal device can receive the first channel or signal on the time domain resource, frequency domain resource and space domain resource indicated by the first transmission parameter, and perform demodulation, decoding, content identification (such as HARQ process, redundancy version, retransmission, new data, etc.) processing on the received first channel or signal based on the first transmission parameter.

[0122] In the uplink transmission scenario, the terminal device can prepare the first channel or signal according to the first transmission parameter, for example, perform encoding, modulation and other processing on the data, and transmit the first channel or signal on the time domain resource, frequency domain resource and space domain resource indicated by the first transmission parameter. Correspondingly, the network device receives the first channel or signal based on the first transmission parameter.

[0123] It should be understood that in mode #A, the terminal device can obtain the complete transmission parameter of the first channel or signal based on the first model and the first information, and then perform uplink transmission or downlink reception based on the complete transmission parameter, which is simple in implementation and has short processing delay.

[0124] Mode #B: The first information is related to the first resource, the network device obtains the first information based on the information related to the first resource and the second model, and the terminal device can determine the first resource based on the first information and the first model. The first resource can further transmit the first transmission parameter of the first channel or signal.

[0125] Referring to FIG. 5, in mode #B, step S210 can be implemented in the following manner:

[0130] It should be noted that the network device determines the first information according to the information about the first resource and the second model in S2101, which can be understood as that the network device can input the information about the first resource into the second model, and output the first information through the second model. In addition, the terminal device determines the first resource based on the first information and the first model in S2301, which can be understood as that the terminal device inputs the first information into the first model, and inputs the information about the first resource through the first model, so as to obtain the first resource.

[0138] It should be noted that the content related to the first frequency domain unit can refer to the related description in way #A, and will not be repeated here for brevity.

[0139] In some embodiments, the space domain information contained in the information about the first resource can indicate one or more of the following:

[0146] It should be noted that the network device can transmit the first transmission parameter of the first channel or signal on all or part of the first resource, and correspondingly, the terminal device can obtain the first transmission parameter of the first channel or signal on all or part of the first resource.

[0147] In some embodiments, the network device can send the first transmission parameter of the first channel or signal on the first resource part of the first resource, and the terminal device receives the first transmission parameter of the first channel or signal on the first resource part of the first resource.

[0148] It should be noted that the first resource part of the first resource can be determined based on one or more of the following:

[0150] In an example, the first resource part of the first resource can be determined according to the predefined information, for example, the protocol can stipulate that the first transmission parameter is transmitted in the first N RE of the first resource, N is an integer greater than or equal to 1.

[0151] In an example, the first resource part of the first resource can be determined based on a preset rule, for example, the first resource part of the first resource can be related to the size of the first resource, such as the first resource part can be one third of the first resource.

[0153] It should be noted that the network device can send the PDSCH on all or part of the resources of the first resource (for example, the first resource part described above), and carry the first transmission parameter through the PDSCH. In this way, the terminal device receives the PDSCH on the first resource to obtain the first transmission parameter. In mode #B, the first transmission parameter can be carried through the PDSCH, and the terminal device does not need to perform blind detection to obtain the first transmission parameter, and the transmission of the PDSCH is related to the system bandwidth, and the capacity is large, which can carry a large amount of information.

[0154] It should also be noted that, on the basis of obtaining the first transmission parameter by using mode #B (i.e., the mode shown in FIG. 5), in a possible implementation, the first channel or signal can be transmitted through the first resource.

[0155] It should be understood that, when the network device and the terminal device transmit the first transmission parameter on the first resource part of the first resource, the network device and the terminal device can transmit the first channel or signal on the remaining resource part of the first resource.

[0156] Specifically, in the case that the network device and the terminal device transmit the first transmission parameter on the first resource part of the first resource in step S2302, with reference to FIG. 6A, the method provided by the embodiments of the present application can further include the following steps:

[0158] It should be noted that the second resource part of the first resource can be determined based on one or more of the following:

[0159] Predefined information; preset rule; configuration information sent by the network device; first transmission parameter.

[0160] In an example, the second resource part of the first resource can be determined according to the predefined information, for example, a protocol can stipulate that the first transmission parameter is transmitted in the last M REs of the first resource, and M is an integer greater than or equal to 1.

[0161] In an example, the second resource part of the first resource can be determined based on the preset rule, for example, the second resource part of the first resource can be related to the size of the first resource, such as the second resource part can be the last half of the resources in the first resource. For another example, the second resource part of the first resource can be other resources in the first resource except the first resource part.

[0162] In an example, the second resource part of the first resource can be configured by the network device, for example, the network device can configure the second resource part through broadcast signaling or dedicated configuration signaling.

Specifically, after the terminal device acquires the first transmission parameter of the first channel or signal in the first resource part of the first resource, the terminal device can send or receive the first channel or signal based on the second resource part indicated by the first transmission parameter.

[0164] It should be noted that, on the basis of acquiring the first transmission parameter in mode #B (i.e., the mode shown in FIG. 5), in another possible implementation, the first channel or signal can be transmitted through the second resource indicated by the first transmission parameter.

[0165] Specifically, in the case that the first transmission parameter of the first channel or signal acquired by the terminal device based on the first resource in step S2302 shown in FIG. 5 further includes information about the second resource (which can also be referred to as second resource information), with reference to FIG. 6B, the method provided by the embodiments of the present application can further include the following steps:

[0177] It should be noted that the spatial domain information of the second resource can refer to the related description in mode #A, and for the sake of brevity, it will not be repeated here.

[0178] It should be understood that in mode #B, since the output of the first model and the input of the second model are only part of the transmission parameters (i.e. the first resource), the model constraint conditions of the first model and the second model are less when designing the model, and the less the model constraint conditions are, the higher the model implementation is, and the better the performance is.

[0205] Predefined information; preset rule; configuration information sent by the network device; first transmission parameter.

[0206] In an example, the first resource part of the third resource can be determined according to the predefined information, for example, the protocol can stipulate that the second transmission parameter is transmitted in the first N RE of the third resource, N is an integer greater than or equal to 1.

[0207] In an example, the first resource part of the third resource can be determined based on a preset rule, for example, the first resource part of the third resource can be related to the size of the third resource, such as the first resource part can be one-third of the resources in the third resource.

[0211] In a possible implementation, the terminal device can send the first channel or signal to the network device on the third resource.

[0212] With reference to FIG. 8A, the method provided by the embodiments of the present application can further include the following steps.

[0213] In S260a, the terminal device can send the first channel or signal in the second resource part of the third resource, and correspondingly, the network device receives the first channel or signal in the second resource part of the third resource.

[0214] It should be understood that when the terminal device sends the second transmission parameter to the network device in the first resource part of the third resource, the terminal device can also send the first channel or signal to the network device in the second resource part of the third resource.

[0215] It should be noted that the second resource part of the third resource can be determined based on one or more of the following:

[0216] Predefined information; preset rule; configuration information sent by the network device; first transmission parameter; second transmission parameter.

[0217] In an example, the second resource part of the third resource can be determined according to the predefined information. For example, a protocol can stipulate that the first transmission parameter is transmitted in the last M REs of the third resource, and M is an integer greater than or equal to 1.

[0218] In an example, the second resource part of the third resource can be determined based on the preset rule. For example, the second resource part of the third resource can be related to the size of the third resource, such as the second resource part can be the last half of the resources in the third resource. For another example, the second resource part of the third resource can be the resources in the third resource other than the first resource part.

[0219] In an example, the second resource part of the third resource can be configured by the network device. For example, the network device can configure the second resource part through broadcast signaling or dedicated configuration signaling.

[0220] In an example, the second resource part of the third resource can also be indicated by the first transmission parameter.

[0221] In an example, the second resource part of the third resource can also be indicated by the second transmission parameter. Specifically, after the network device acquires the second transmission parameter in the first resource part of the third resource, the network device can receive the first channel or signal based on the second resource part indicated by the second transmission parameter.

[0222] In a possible implementation, the terminal device can send the first channel or signal to the network device on a new resource (denoted as a fourth resource in the embodiments of the present application) indicated by the second transmission parameter.

[0223] It should be understood that in FIG. 7, the second transmission parameter of the first channel or signal sent by the terminal device based on the third resource in step S250 can also include information about the fourth resource.

[0224] It should be noted that the information about the fourth resource can include one or more of the following:

[0226] In some embodiments, the time domain resource information included in the information about the fourth resource can indicate one or more of the following:

[0227] The first time unit; the remaining time domain resources in the first time unit except for the reserved time domain resources; the partial time domain resources included in the first time unit.

[0236] S260b, the terminal device sends the first channel or signal on the fourth resource, and correspondingly, the network device receives the first channel or signal on the fourth resource.

[0237] Through the method provided in the embodiments of the present application, the terminal device can report the transmission parameters of the first channel or signal determined by itself, so that the output parameters of the first model and the input parameters of the second model can not necessarily include all the transmission parameters of the first channel or signal, that is, the model constraint conditions of the first model and the second model in the model design are less, and the higher the model realizability is, the better the performance is.

[0238] The configuration manner of the first model is introduced below.

[0239] In an embodiment of the present application, with reference to FIG. 9, the method provided in the embodiments of the present application can further include the following steps:

[0240] S201, the terminal device sends or receives second information, and correspondingly, the network device receives or sends the second information, and the second information is used to determine the first model.

[0241] It should be noted that the second information is carried by one or more of the following:

[0243] In an example, the terminal device can determine the first model used by itself and send the second information to the network device to determine the first model through the second information. At this time, the second information can be carried by one or more of the uplink control information, the UE capability information, the RRC signaling and the MAC CE, and the embodiments of the present application do not limit this.

[0244] In an example, the first model used by the terminal device can be determined by the network device. That is, the network device can determine the first model used and determine the first model through the second information. At this time, the second information can be carried by one or more of the broadcast signaling (such as a system message or synchronization information), the RRC signaling, the UE dedicated signaling, the MAC CE and the first information, and the embodiments of the present application do not limit this.

[0245] In some embodiments, the second information can include one or more of the following:

[0246] identification information of the first model; index information of the first model; function information of the first model; service characteristics (including data volume, reliability, delay, etc.); channel transmission characteristics (including antenna configuration, spatial channel characteristics, interference level, mobile speed, channel fading characteristics, etc.); service cell characteristics (including cell coverage, base station capability / version, single-carrier operation mode or carrier aggregation operation mode, etc.); and capability of the terminal device.

[0247] In a possible implementation, the second information can directly indicate the first model.

[0248] Exemplarily, the second information can indicate one or more of the following: identification information of the first model; index information; and functionality.

[0249] It should be noted that the functionality can be understood as information capable of defining or describing the functionality of the first model, expressing or indicating the model, and / or the functionality, usage mode, condition, etc. of the model.

[0250] In some embodiments, the functionality information can include one or more of the following:

[0251] characteristics of input and / or output information; performance requirements; data sets; data set identification; usage scenario information; usage condition information.

[0252] In another possible implementation, the second information can implicitly indicate the first model.

[0253] Exemplarily, the second information can indicate one or more of the following: service characteristics; channel transmission characteristics; serving cell characteristics; and capability of the terminal device.

[0254] It should be understood that different models are applicable to different application scenarios, and the application scenarios can be affected by multiple factors, for example, service characteristics (data volume, reliability, latency, etc.), uplink and / or downlink channel transmission characteristics (antenna configuration, spatial channel characteristics, interference level, mobile speed, channel fading characteristics, etc.), serving cell characteristics (cell coverage, base station capability / version, single-carrier working mode or carrier aggregation working mode), and capability of the terminal device. Based on this, the first model can be characterized by one or more of the following: service characteristics; channel transmission characteristics; serving cell characteristics; and capability of the terminal device.

[0255] In some embodiments, the first model can be any one of a plurality of third models, and the plurality of third models are determined based on one or more of the following:

[0256] predefined information; and configuration information sent by the network device.

[0257] In some embodiments, any one of the plurality of third models can be related to one or more of the following:

[0258] service characteristics (including data volume, reliability, latency, etc.); channel transmission characteristics (including antenna configuration, spatial channel characteristics, interference level, mobile speed, channel fading characteristics, etc.); serving cell characteristics (including cell coverage, base station capability / version, single-carrier working mode or carrier aggregation working mode, etc.); and capability of the terminal device.

[0259] It should be understood that the network device or the terminal device can select one of the plurality of third models as the first model. Specifically, the second information can activate one of the plurality of third models.

[0260] In some embodiments, the resource for sending or receiving the second information can be a periodic resource.

[0261] It should be understood that the sending resource of the second information has a periodicity, and the terminal device or the network device can send the second information on the periodic resource. It should be noted that the terminal device or the network device does not necessarily send the second information every period.

[0262] In some embodiments, the second information can act on one or more first information.

[0263] It should be noted that the second information acting on one or more first information can be understood as the second information being valid for one or more first information, or in other words, the first model indicated by the second information being used to process one or more first information.

[0264] In an example, the second information is valid once, that is, the second information is valid for one first information. In this example, the second information can be carried by the first information, and the second information can indicate the first model corresponding to the first information of the current transmission.

[0265] In another example, the second information can be valid for a plurality of first information.

[0266] It should be noted that the plurality of first information can include the first information sent or received within a first time length after the second information is sent or received. That is, the second information can be valid within the first time length.

[0267] It should be noted that the first time length is determined based on one or more of the following:

[0268] Predefined information; configuration information sent by the network device; the second information; time information of the first second information sent or received after the second information.

[0269] It should be understood that the first time length can be agreed upon by the protocol or configured by the network device. Alternatively, the first time length can be indicated in the second information. Alternatively, the first time length is the length of time between the second information and the first second information received after the second information, that is, the second information is valid until the first second information is received after the second information.

[0270] In some embodiments, with reference to FIG. 9, the method provided by the embodiments of the present application can further include the following:

[0271] S202, the terminal device receives or transmits third information, and correspondingly, the network device transmits or receives the third information. The third information is used to indicate whether the second information is received successfully.

[0272] It should be noted that step S202 is an optional step, which is shown by a dashed line in FIG. 9.

[0273] It should be understood that the network device and the terminal device can perform confirmation for the reception of the second information.

[0274] It should be noted that the third information can be confirmation information of the second information, or interactive information, or feedback response information. The third information can confirm the content transmitted by the second information, so as to ensure that the network device and the terminal device have consistent understanding of the first model used subsequently.

[0275] It should be noted that for the case that the second information is valid for a long time, the confirmation step is very important, and the terminal device and the network device need to confirm the second information. For the case that the second information is valid for a single time, the network device and the terminal device can not perform confirmation.

[0276] In summary, in the method provided by the embodiments of the present application, the network device can not transmit the actual transmission parameters of the first channel or signal, but transmit the first information processed based on the second model. In this way, the terminal device can restore the actual transmission parameters of the first channel or signal based on the first information and the first model. It can be understood that the number of bits of the first information transmitted between the network device and the terminal device is significantly smaller than the number of bits of the original transmission, which reduces the amount of information actually transmitted to a certain extent. In addition, the network device can also process more fine transmission parameters through the second model to obtain the first information, so as to realize more fine scheduling. That is, the transmission parameter determination method provided by the embodiments of the present application can realize more fine scheduling and / or reduce the amount of information actually transmitted, thereby improving the system efficiency.

[0277] The method provided by the embodiments of the present application will be described in detail in combination with specific application scenarios.

[0278] The embodiments of the present application provide a model-based scheduling information transmission method, which aims to realize more fine scheduling and / or reduce the amount of information actually transmitted, thereby improving the system efficiency.

[0279] Referring to the network architecture of a new AI-based scheduling information obtaining method shown in FIG. 10, in this kind of method, the sending end can use an encoding model to process the obtained original scheduling information into transmission information (the number of bits of the transmission information is significantly smaller than the number of bits of the original scheduling information directly transmitted). After receiving the transmission information, the receiving end can use a corresponding decoding model to restore the scheduling information from the transmission information.

[0280] In the embodiments of the present application, the terminal device can perform downlink reception and / or uplink transmission according to the scheduling information, wherein the scheduling information is obtained based on the transmission information and the processing model.

[0281] The role of the processing model is described below.

[0282] The transmission information is used as input information of the processing model, and after processing, parameters used by the transmission data or the physical channel are obtained. It can be understood that the model input is a set of parameters without specific physical meaning, and the output parameter is the scheduling information, including one or more of the following information:

[0283] 1) Time domain resource information.

[0284] In an implementation manner, the time domain resource information can include a first time unit (such as a frame, a subframe, a time slot, a sub-time slot, N symbols) occupied.

[0285] If one first time unit is occupied, it means that all time domain resources (or all resources except the conventionally reserved resources) of the first time unit are occupied, and the time domain resource information only includes the occupied first time unit. For example, if one time slot or subframe is occupied, it means that all symbols in the time slot or subframe are used, or all symbols in the time slot or subframe except the conventionally reserved resources are used. The conventionally reserved resources include pre-configured resources, or resources for transmitting downlink control signaling, a downlink control channel, uplink control signaling, a downlink reference signal, an uplink reference signal, a synchronization signal, a broadcast signal, a broadcast channel, and one or more of a random access signal.

[0286] In another implementation manner, if the first time unit includes a plurality of second time units (such as symbols), the time domain resource information further includes the occupied second time units. The second time unit can be K symbols (if the first time unit is L symbols, K is less than or equal to L), and K is a positive integer.

[0287] It should be noted that the occupied first time unit / second time unit can be identified by the position and / or quantity of the first time unit / second time unit. The receiving end and the transmitting end understand the position and / or quantity of the occupied first time unit / second time unit consistently. When the occupied first time unit / second time unit includes a plurality of time units, the plurality of time units can be continuous time units or discontinuous time units.

[0288] 2) Frequency domain resource information.

[0289] In an implementation, the frequency domain resource information can include an occupied first frequency domain unit (e.g., a cell, a carrier, a frequency band, a frequency band, a partial bandwidth (e.g., a sub-band, a BWP) in one carrier / cell / frequency band, a sub-carrier, a resource block (RB), a sub-band).

[0290] If one first frequency domain unit is occupied, it means that all frequency domain resources (or all resources except for an agreed reserved resource) of the first frequency domain unit are occupied, and the frequency domain resource information only includes the occupied first frequency domain unit. For example, if one sub-band is occupied, it means that all frequency domain resources (sub-carriers or RBs) in the sub-band are used, or all frequency domain resources in the sub-band except for an agreed resource are used, and the agreed resource includes a pre-configured resource or a resource used for transmitting one or more of the following: downlink control signaling, a downlink control channel, uplink control signaling, a downlink reference signal, an uplink reference signal, a synchronization signal, a broadcast signal, a broadcast channel, and a random access signal.

[0291] In an implementation, if the first frequency domain unit includes a plurality of second frequency domain units (e.g., sub-carriers, resource blocks (RBs), or sub-bands), the frequency domain resource information further includes the occupied second frequency domain units. The second time unit can be K sub-carriers or resource blocks (if the first time unit is a sub-carrier or a resource block, K is less than or equal to L), and K is a positive integer.

[0292] It should be noted that the occupied first / second frequency domain unit can be identified by the position and / or quantity of the first / second frequency domain unit. The receiving end and the sending end should have a consistent understanding of the position and / or quantity of the occupied first / second frequency domain unit. When the occupied first / second frequency domain unit includes a plurality of frequency domain units, the plurality of frequency domain units can be continuous frequency domain units or discontinuous frequency domain units.

[0293] 3) Spatial domain information.

[0294] For example, the spatial domain information can include antenna (port) information, transmission mode information (transmit diversity or spatial multiplexing, etc.), precoding information, transmission layer information, etc., and the embodiments of the present application do not limit this.

[0295] 4) Modulation and / or coding information.

[0296] For example, the modulation and / or coding information includes a modulation method, a modulation order, a channel coding method, a coding rate, etc., and the embodiments of the present application do not limit this.

[0297] 5) Resource mapping method information.

[0298] Exemplarily, the resource mapping manner information can include non-interleaving mapping, interleaving scheme (implying post-interleaving mapping), resource mapping rule (such as time first and frequency second, frequency first and time second), non-frequency hopping, frequency hopping, or frequency hopping parameter, etc., which are not limited by embodiments of the present application.

[0299] 6) data amount information.

[0300] Exemplarily, the data amount information can be bit quantity, TBS, payload, etc.

[0301] It should be noted that the data amount can be a determined value or a value range.

[0302] In an implementation manner of the present application, the terminal device can perform data or physical channel receiving (for downlink, specifically including demodulation, decoding, content identification (identifying HARQ process, redundancy version, retransmission, new data, etc.) processing, etc.) or data preparation (for uplink) according to the parameter output by the processing model.

[0303] It can be understood that the parameter output by the processing model is complete scheduling information, that is, in addition to the above-mentioned information, it can further include HARQ process related parameters, redundancy version information, feedback information transmission parameter (that is, the related parameter of transmitting ACK / NACK information corresponding to downlink data), etc. After obtaining all the scheduling information based on the model, the data receiving or sending can be performed, the implementation is simplified, and the processing delay is shorter.

[0304] In another implementation manner of the present application, the terminal device can determine the physical resource (time, frequency, and spatial domain) used for transmission according to the parameter output by the processing model. For downlink transmission, the terminal device can complete complete reception of the downlink transmission including demodulation, decoding, content identification, etc. processing only after further obtaining other indication information in the determined physical resource (at this time, the transmission capacity is basically not limited, and blind detection is not needed).

[0305] For uplink transmission, the terminal device can determine the actual data content transmitted in the physical resource by itself, and send first information in the physical resource, the first information being used for indicating the parameter of the data transmitted in the physical resource, such as HARQ process information, data amount, redundancy version information, new data indication information, used physical resource (part of the resource in the physical resource, that is, the base station configures a larger resource, and the terminal can only use part of the resource), etc. In this method, the model needs to consider only a small amount of information during design, and the less the model constraint condition is, the higher the model implementability is, and the better the performance is.

[0306] The configuration of the processing model is introduced below.

[0307] In particular, the processing model can be obtained according to network configuration information or terminal reporting information. The processing model includes an encoding end model and / or a decoding end model.

[0308] In an implementation, a network device or a terminal device sends information indicating the processing model. The information can be broadcast signaling, UE-specific signaling, RRC signaling, MAC CE, uplink control information, UE capability information, etc. The information can directly indicate the processing model, i.e., indicating identification information that can distinguish the model, such as a model ID or index, etc. The information can also be used to define and / or indicate the functionality of the model, such as by defining and / or indicating one or more of the following: characteristics of input and / or output information, performance requirements, a data set, a data set identifier, usage scenario information, usage condition information, etc., to express or indicate the model, and / or the functionality, usage mode, condition, etc. of the model.

[0309] In another implementation, a network device or a terminal device sends configuration information indicating multiple processing models (characteristics of the processing models are as described above). Different processing models are applicable to different application scenarios. The application scenarios can be affected by multiple factors, such as service characteristics (data volume, reliability, latency, etc.), uplink and / or downlink channel transmission characteristics (antenna configuration, spatial channel characteristics, interference level, mobile speed, channel fading characteristics, etc.), serving cell characteristics (cell coverage, base station capability / version, single-carrier operation mode or carrier aggregation operation mode), terminal capability, etc. The network device or the terminal device sends second information indicating or activating one of the multiple models. The second information can be MAC CE, downlink control signaling, uplink control information, etc. The second information has one of the following characteristics:

[0310] 1) The sending position of the second information has periodic characteristics (it can be sent on a periodic resource, but it is not necessary to be sent every period).

[0311] 2) The effective time of the second information is T, the length of T is agreed by a protocol, indicated by a base station, or indicated by the second information, or the end position of the effective time T is the first piece of the second information received after the second information (or described as: the second information is valid until the first piece of the second information received after the second information).

[0312] 3) The second information is valid for a single time. For example, the second information is included in the transmission information, and the second information is used to indicate the processing model corresponding to the current transmission information.

[0313] 4) According to the receiving situation of the second information, the network device and the terminal device can perform confirmation. That is, after A sends the second information to B, B needs to send confirmation information or interaction information or feedback response information to A for the receiving situation of the second information, so as to ensure that the two ends understand the model for subsequent use. This step is particularly important in the case of long validity of the second information. In the case of single validity, confirmation can not be performed.

[0314] In summary, the method provided by the embodiments of the present application can realize more fine scheduling and / or reduce the amount of information actually transmitted, thereby improving system efficiency.
