Description

Communication method, apparatus and computer readable storage medium

[0001] The present application claims priority to the Chinese patent application No. 202410869269.7, filed on June 28, 2024, and entitled "A communication method, apparatus and computer readable storage medium", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of wireless communication, and in particular to a communication method, apparatus and computer readable storage medium. BACKGROUND

[0003] With the rapid development of mobile communication technology, more and more application scenarios have put forward higher communication requirements for wireless communication networks, such as vehicle networking services, intelligent body (such as artificial intelligence (AI) mobile phones, AI assistant devices, etc.) services, etc. In addition to the requirements of transmission rate and low latency, more reliable communication transmission and higher throughput are usually required.

[0004] At present, when transmitting services, the base station can usually configure time-frequency resources for the terminal in a dynamic scheduling manner or a semi-static scheduling manner. Although the dynamic scheduling manner can change flexibly according to the service requirements, each scheduling needs related control signaling, and the resource overhead and latency are large. Although the semi-static scheduling manner can effectively reduce the transmission latency, the time-frequency resources, modulation and coding scheme (MCS), transmission power control (TPC) and a series of transmission parameters configured for the terminal by using the semi-static scheduling manner may not be able to flexibly adapt to the channel changes and network characteristic changes of the terminal, so that the time-frequency resources allocated for the terminal cannot match the higher efficient transmission data of the channel, resulting in low spectrum efficiency.

[0005] In summary, the dynamic scheduling manner or the semi-static scheduling manner may not be able to well support future large bandwidth, low latency and high reliability services, and it is difficult to guarantee user experience. SUMMARY

[0006] The present application provides a communication method, apparatus and computer readable storage medium to reduce latency and improve spectrum efficiency.

[0007] To achieve the above technical purposes, the embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, a communication method is provided. The method can be performed by a communication apparatus. The communication apparatus can be an access network device (e.g., a radio access network (RAN) device), a component (e.g., a processor, a chip, or a chip system) in the access network device, or a logic module or software that can implement all or part of the functions of the access network device. Hereinafter, the method is described by taking the communication apparatus as an example. The method includes: obtaining first information, second information, and third information of a first terminal, the first information being used to describe configuration parameters, a location, a motion state, and / or a capability of the first terminal at a first time unit, the second information being used to reflect a channel characteristic of the first terminal under the first information, and the third information being used to reflect a first service requirement of the first terminal. According to the first information, the second information, and the third information, a first transmission resource and values of V1, V2, …, Vm of m transmission parameters of the first terminal at a second time unit are predicted, where V1, V2, …, Vm correspond to the first transmission resource, m is an integer greater than or equal to 1, and the second time unit is later than the first time unit. A first message including fourth information is sent to the first terminal, where the fourth information indicates the first transmission resource and the values of the m transmission parameters. m V1, V2, …, Vm are values of the m transmission parameters. m The first transmission resource is used to guarantee the first service requirement, the m transmission parameters correspond to the first transmission resource, and m is an integer greater than or equal to 1.

[0009] In the method, the first information, the second information, and the third information of the first terminal are obtained, and then according to the first information, the second information, and the third information, the first transmission resource and the values of the m transmission parameters corresponding to the first transmission resource of the first terminal at the second time unit are predicted. Since the first information is used to describe the configuration parameters, the location, the motion state, and / or the capability of the first terminal at the first time unit, the second information is used to reflect the channel characteristic of the first terminal under the first information, and the third information is used to reflect the first service requirement of the first terminal, the first transmission resource and the values of the transmission parameters corresponding to the first transmission resource of the first terminal at the second time unit can be predicted based on the above information of the first terminal at the first time unit, and then the first transmission resource and the values of the transmission parameters corresponding to the first transmission resource can be configured for the first terminal in advance. Since the first transmission resource is configured for the first terminal in advance, the scheduling delay can be reduced compared with the prior art. In addition, since the above information of the first terminal is used to predict the transmission resource and the values of the transmission parameters of the first terminal at the second time unit, the channel at the second time unit can be better adapted and matched, and thus the data can be transmitted more efficiently, and the spectrum efficiency can be improved.

[0010] In a possible implementation, the first time unit can be a current time unit or a historical time unit.

[0011] In a possible implementation, the first transmission resource and the values of the m transmission parameters of the first terminal in the second time unit are predicted according to the first information, the second information, and the third information, and V1, V2, …, V m comprising: predicting the first transmission resource and the values of the m transmission parameters of the first terminal in the second time unit according to the first information, the second information, and the third information, and fifth information of the access network device. The fifth information is used to determine the available transmission resource, and the available transmission resource includes the first transmission resource. In predicting the first transmission resource and the values of the m transmission parameters of the first terminal in the second time unit, the available transmission resource of the access network device is further combined, so that the first transmission resource allocated for the first terminal in the second time unit can avoid collision with transmission resources of other terminals.

[0012] In a possible implementation, the fifth information includes one or more of the following information: a scheduling strategy, a scheduling resource, and a spectrum efficiency of the access network device.

[0013] In a possible implementation, the first transmission resource and the values of the m transmission parameters (V1, V2, …, V m ) are obtained by the first information, the second information, and the third information through a first artificial intelligence (AI) model. The first transmission resource and the values of the m transmission parameters are predicted through the first AI model, so that the first transmission resource and the values of the m transmission parameters predicted for the first terminal are more reasonable.

[0014] In a possible implementation, the first message is a radio resource control (RRC) message. The first transmission resource and the value of any of the m transmission parameters are indicated through the RRC message, so that the latency can be reduced.

[0015] In a possible implementation, the fourth information includes information of the first transmission resource and information indicating the value of any of the m transmission parameters.

[0017] In a possible implementation, after the first message is sent, the method further includes: determining a second transmission resource corresponding to the second time unit and / or updated values of the m transmission parameters of the first terminal. The second transmission resource is an updated transmission resource of the first terminal in the second time unit. A second message is sent to the first terminal, and the second message includes ninth information, where the ninth information is used to indicate the second transmission resource and the updated values of the m transmission parameters. For example, the second message can be a DCI or an RRC message, and the embodiments of the present application do not limit this.

[0018] In a possible implementation, the determination of the second transmission resource corresponding to the second time unit and / or the updated values of the m transmission parameters of the first terminal includes: obtaining sixth information, seventh information, and eighth information of the first terminal, where the sixth information is used to describe configuration parameters, positions, motion states, and / or capabilities of the first terminal in a third time unit; the seventh information is used to reflect channel characteristics of the first terminal under the sixth information; and the eighth information is used to reflect a second service requirement of the first terminal, where the third time unit is later than the first time unit and earlier than the second time unit. According to the sixth information, the seventh information, and the eighth information, the second transmission resource and V1', V2',..., V m ' of the first terminal in the second time unit are predicted. m ' are updated values of the m transmission parameters, the second transmission resource is used to guarantee the second service requirement, and the updated values of the m transmission parameters correspond to the second transmission resource.

[0019] In a possible implementation, the values of the m transmission parameters are determined according to a channel state of the first terminal in the second time unit, and the channel state of the first terminal in the second time unit is predicted according to the second information and the third information. In this way, the values of the m transmission parameters corresponding to the first transmission resource and determined for the first terminal can be more adapted to the channel state of the first terminal in the second time unit.

[0020] In a possible implementation, the updated values of the m transmission parameters are determined according to a channel state of the first terminal in the second time unit, and the channel state of the first terminal in the second time unit is predicted according to the seventh information and the eighth information. In this way, the updated values of the m transmission parameters corresponding to the first transmission resource and determined for the first terminal can be more adapted to the channel state of the first terminal in the second time unit.

[0021] In a possible implementation, the fourth information further indicates that the first transmission resource corresponds to periodic service or aperiodic service.

[0022] In a possible implementation, the fourth information further indicates a period corresponding to the first transmission resource.

[0027] In a possible implementation, after the first terminal receives the first message from the access network device, the method can further include: buffering, by the first terminal, the first transmission resource corresponding to the second time unit and the values of the m transmission parameters. In this way, when the first terminal determines that data transmission is needed subsequently, the first terminal can perform data transmission through the first transmission resource and the values of the m transmission parameters in the second time unit.

[0028] In a possible implementation, after the first terminal receives the first message from the access network device, the method can further include: receiving, by the first terminal, a second message from the access network device, the second message including ninth information. The ninth information is used to indicate a second transmission resource and updated values of the m transmission parameters. For example, the second message can be a DCI or an RRC message, which is not limited in the embodiments of the present application. The first terminal determines the second transmission resource as the transmission resource of the second time unit and / or the updated values of the m transmission parameters as the values of the transmission parameters corresponding to the second time unit according to the ninth information.

[0030] In a possible implementation, after receiving the first message from the access network device, the first terminal can perform data transmission on the first transmission resource according to the values of the m transmission parameters at the second time unit when there is a data transmission demand.

[0031] In a possible implementation, the method further includes: reporting, by the first terminal, the first information, the second information, and the third information of the first terminal to the access network device. The first information, the second information, and the third information correspond to the first time unit. The first information, the second information, and the third information are used for predicting the transmission resource corresponding to the second time unit and the parameter values of the m transmission parameters of the first terminal.

[0072] Before introducing the embodiments of the present application, the related terms involved in the present application are described as follows:

[0073] 1、Downlink Control Information (DCI): control information used for scheduling downlink data channels (such as physical downlink shared channels) or uplink data channels (such as physical uplink shared channels) or other control information sent through the downlink, etc.

[0074] 2、Modulation and coding scheme, including: quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (16QAM), 64 quadrature amplitude modulation (64QAM), and 256 quadrature amplitude modulation (256QAM).

[0075] Different modulation methods use different channel coding efficiencies. Among them: QPSK modulates 2 information bits into one modulation symbol. 16QAM modulates 4 information bits into one modulation symbol. 64QAM modulates 6 information bits into one modulation symbol. 256QAM modulates 8 information bits into one modulation symbol.

[0076] In order to make the embodiments of the present application clearer, the following briefly describes some of the contents involved in the embodiments of the present application:

[0077] In LTE and NR systems, shared channels are used to transmit data, and time-frequency resources are dynamically shared between one or more terminals. The base station of the LTE and NR systems decides to allocate time-frequency resources to each terminal to transmit data. The base station achieves the allocation of uplink and downlink time-frequency resources through scheduling. Scheduling refers to the base station complying with the frame structure configuration to allocate shared channel resources to the terminal in a certain scheduling basic unit in the time domain allowed by the frame for system message or user data transmission. In the scheduling process, the priority of the service is considered first, and the MCS is determined to allocate appropriate time-frequency resources to the terminal.

[0078] Scheduling unit: the basic scheduling unit in the time domain is a time slot. Referring to the PUSCH / PDSCH related configuration, the time domain resource allocation scheduling type is divided into Type A and Type B.

[0079] In frequency domain: the minimum resource allocation unit is resource block (RB), which contains 12 subcarriers in frequency domain. Frequency domain scheduling types are divided into Type 0 and Type 1. Type 0 is the allocation mode of RBG granularity, which supports non-continuous allocation and continuous allocation. Type 1 is the allocation mode of RB granularity, which supports continuous allocation.

[0080] The scheduling function is realized by the scheduler, which is located in the MAC layer of the NR system. The basic function is to allocate appropriate time-frequency resources for UEs in the cell for sending and receiving data every time slot. According to the scheduling direction, it is divided into downlink scheduler and uplink scheduler. The downlink scheduler is used for downlink scheduling. The uplink scheduler is used for uplink scheduling.

[0081] The downlink scheduler allocates resources on the physical downlink shared channel (PDSCH) for UEs and selects appropriate MCS for the transmission of system messages or user data. Its functions are:

[0082] Allocating time-frequency domain resources on PDSCH for UEs.

[0083] Allocating demodulation reference signal (DMRS) resources for UEs to demodulate PDSCH.

[0084] Selecting appropriate MCS for UEs for the transmission of system messages or user data.

[0085] The uplink scheduler allocates resources on the physical uplink shared channel (PUSCH) for UEs and selects appropriate MCS for the transmission of user data. Its functions are:

[0086] Allocating time-frequency domain resources on PUSCH for UEs.

[0087] Allocating DMRS resources for UEs to demodulate PUSCH.

[0088] Selecting appropriate MCS for UEs for the transmission of service data.

[0089] Scheduling process: taking scheduling of service data of a single UE as an example, the information that the scheduler needs to schedule in actual scheduling includes control plane information and data plane information.

[0090] In the communication process, a scheduling process needs to be used, which can transmit data between the base station and the terminal to realize the communication service of the terminal and the base station.

[0091] The scheduling between the terminal and the base station in the channel direction can be divided into uplink scheduling and downlink scheduling.

[0092] 1. Downlink scheduling refers to that the base station allocates downlink resources (such as downlink time-frequency resources) for the terminal to receive downlink data through scheduling.

[0093] Downlink scheduling can be divided into downlink dynamic scheduling and downlink semi-persistent scheduling (also known as downlink semi-static scheduling (SPS)). The processes of downlink dynamic scheduling and downlink semi-persistent scheduling will be described respectively.

[0094] (a) The basic process of downlink dynamic scheduling includes the following steps:

[0095] Step 1: The gNodeB obtains the channel state of the UE, and the UE capability and the like information.

[0096] For example, the channel state reported by the UE can be reflected by the reference signal strength, the channel gain matrix, and the like. The CSI can include a precoding matrix indicator (PMI), a rank indication (RI) of the matrix, or a channel quality indicator (CQI).

[0097] The CQI is a signal quality level value, which is used to reflect whether the current channel quality of the UE is good or poor.

[0098] The gNodeB determines the size of the transmitted data block, the encoding mode of the PDSCH channel, and the modulation mode according to the size of the CQI.

[0099] For example, the UE capability can include one or more of the following: the transmission bandwidth of the UE, the maximum transmission power, and the like, the number of ports, the number of antennas, and the like.

[0100] Step 2: The gNodeB allocates downlink time-frequency resources for the UE according to the channel state of the UE, in combination with the UE capability and the like.

[0101] The UE capability includes the transmission power of the UE, the number of antennas of the UE, the number of antenna ports of the UE, and the like.

[0102] The channel state of the UE can be represented by the channel gain matrix of the UE.

[0103] Step 3, the gNodeB sends a physical downlink control channel (PDCCH) to the UE. The PDCCH includes downlink control information (DCI). The DCI indicates scheduling information to the UE.

[0104] The scheduling information includes downlink time-frequency resources, a modulation order of the MCS, and a first transmission layer number scheduled by the gNodeB for the UE.

[0105] Specifically, the downlink time-frequency resources include downlink time domain resources and downlink frequency domain resources. The downlink time domain resources can be orthogonal frequency division multiplexing (OFDM) symbols. The downlink frequency domain resources can be resource blocks (RBs) or resource block groups (RBGs).

[0106] The downlink time-frequency resources are used to carry data transmitted between the gNodeB and the UE. The data can be downlink data. The MCS order of the MCS is used to determine the modulation order and channel coding rate of the data transmission of the PDSCH.

[0107] For example, the modulation order can be 2, 4, 6, or 8, corresponding to quadrature phase shift keying (QPSK), 16QAM, 64QAM, and 256QAM, respectively.

[0108] The channel coding rate can be 490 / 1024, 948 / 1024, etc. The first transmission layer number is the number of data streams of the downlink data sent by the gNodeB to the UE or the number of data streams of the uplink data sent by the UE, which can also be referred to as the first transmission layer number or the first transmission order or the first transmission rank.

[0109] For the downlink time-frequency resources in the scheduling information, the frequency domain resource indication field and the time domain resource indication field in the DCI can be used to jointly indicate. For the modulation order of the MCS in the scheduling information, the MCS field in the DCI can be used to indicate.

[0110] It should be noted that the name of the scheduling information is only exemplary, and other names such as initial scheduling information, initial scheduling information, pre-scheduling information, etc. can also be used, which are not limited in the present application.

[0111] Step 4, the gNodeB sends downlink data on the physical downlink shared channel (PDSCH) allocated to the UE.

[0112] Optionally, the information in the PDCCH control channel also indicates how the UE parses the data in the PDSCH.

[0113] (b) Downlink Semi-static Scheduling (also known as Semi-Persistent Scheduling, SPS).

[0114] As shown in FIG. 1, the process of downlink semi-static scheduling can be summarized as follows:

[0115] 1. The base station sends RRC (RRC Setup or RRC Reconfiguration) signaling, which includes the transmission resources of PDSCH data. A series of parameters such as MCS, resource period, etc. are configured in the RRC signaling.

[0116] 2. The UE monitors the PDCCH.

[0117] 3. When the base station wants to start PDSCH transmission, the base station sends DCI based on Configured Scheduling (CS) - Radio Network Temporary Identifier (RNTI) to activate the CG configuration.

[0118] Then the UE can receive PDSCH on the corresponding time-frequency resources according to the RRC configuration, according to the MCS and other parameters set by the base station.

[0119] II. Uplink Scheduling

[0120] Uplink scheduling is divided into uplink dynamic scheduling and uplink grant-free scheduling. The basic process of dynamic scheduling is as follows, which can be flexibly changed according to the business needs, but each scheduling needs related control signaling, resource overhead is large.

[0121] 1. The UE sends a scheduling request (SR) to the gNodeB through the uplink channel. For example, the SR is used to request the resources for uplink data transmission. For example, the uplink channel can be a physical uplink control channel (PUCCH) or a physical random access channel (PRACH).

[0122] 2. The gNodeB responds to the SR and sends DCI to the UE through the PDCCH.

[0123] The uplink time-frequency resources allocated by the gNodeB to the UE are indicated in the DCI. For example, the DCI indicates the slot in which the scheduled uplink time-frequency resources are located, and the start and end positions of the scheduled OFDM symbols within the slot.

[0124] 3. After receiving the DCI, the UE uploads the buffer status report (BSR) according to the allocated resources. The BSR is used to indicate the size of the data to be sent by the UE.

[0125] 4. The gNodeB continues to schedule and send DCI according to the BSR to find out if the UE has remaining data to be uploaded.

[0126] 5. The UE uploads data according to the instructions.

[0127] In addition to dynamic allocation of time-frequency domain resources by PDCCH DCI for uplink and downlink scheduling, transmission can also be performed by pre-configured grant (CG). For PUSCH, the corresponding transmission is configured grant type 1 and configured grant type 2.

[0128] Uplink grant-free scheduling: After the gNodeB issues an uplink grant to the UE, the UE can use the resources indicated by the uplink grant for uplink transmission at all times, unless the UE receives an instruction to deactivate the uplink grant.

[0129] The allocation of CG resources is semi-static scheduling. After the base station allocates GC resources to the terminal, the terminal can use the allocated resources in the future period. Specifically, the base station can configure a periodical time-domain resource for the terminal. The CG resources can include configured grant type 1 (CG1) and configured grant type 2 (CG2). CG1 is a transmission resource directly configured by the base station to the terminal through RRC message. The terminal can directly use the transmission resource. CG2 is a transmission resource configured by the base station through RRC signaling, and the transmission resource is activated through DCI in PDCCH.

[0130] Configured grant Type 1: all parameters are configured by the ConfiguredGrantConfig information element in RRC signaling.

[0131] Configured grant Type 2: Common parameters are configured by the ConfiguredGrantConfig information element in RRC signaling, and scheduling parameters are configured by a DCI message to indicate activation and deactivation. When the UE's grant-free scheduling configuration needs to be modified, the UE needs to be deactivated and then reactivated through the DCI.

[0132] The time-frequency resource location of the configured grant Type 1, the period of the CG resource, the MCS, and other parameters are provided by the network device to the terminal through radio resource control (RRC) signaling and stored by the terminal as a configured uplink grant. After the RRC signaling configures the configured grant Type 1, the terminal can use the configured grant for uplink data transmission.

[0133] The period of the CG resource, the number of HARQ processes using the CG resource, and which MCS table to use for the configured grant Type 2 are provided by the network device to the terminal through RRC signaling, but the time-frequency resource location, the MCS index value, and other parameters are provided by the network device to the terminal through DCI and stored by the terminal as a configured uplink grant. That is, the configured grant Type 2 is activated or deactivated by physical layer or layer 1 (L1) signaling.

[0134] The configured grant Type 1 and the configured grant Type 2 are distinguished according to the field rrc-ConfiguredUplinkGrant in the ConfiguredGrantConfig information element. If the field is included in the field domain in the ConfiguredGrantConfig information element, it indicates that the configured grant is the configured grant Type 1. If the field is not configured in the field domain in the ConfiguredGrantConfig information element, it is the configured grant Type 2.

[0135] For the configured grant Type 1, as shown in (a) of FIG. 2:

[0136] 1. The base station configures the PUSCH data transmission resource through the parameter SPS-Config in the RRC signaling, which configures a series of parameters such as MCS, resource period, RI, time-frequency resource location, and the like.

[0137] 2. After the UE processes the RRC, the UE can directly use the resource configured by the RRC without the need for physical layer signaling activation.

[0138] For the configured grant Type 2, as shown in (b) of FIG. 2:

[0139] 1. The base station configures the PUSCH data transmission resource through the parameter SPS-Config in the RRC signaling, which configures a series of parameters such as MCS, resource period, RI, time-frequency resource location, etc.

[0140] 2. When the base station authorizes the PUSCH resource, the base station sends the DCI signaling based on the CS_RNTI to activate the CG resource configured by the RRC.

[0141] 3. After the UE processes the above-mentioned DCI, the UE can send the PUSCH on the resource indicated by the RRC.

[0142] As shown above, the semi-static scheduling mode currently adopted by the cellular network is very inflexible. For example, the MCS used for transmission, the TPC used for transmission, the time-frequency resource, etc. configured by the network device for the terminal through the RRC message / signaling usually cannot adapt to the channel change of the terminal. As shown in FIG. 3, it is assumed that the base station allocates periodic time-frequency resource A for the terminal based on the channel state information reported by the terminal, and the MCS corresponding to the time-frequency resource A is 5, and the Rank Indication (RI) is 1. For example, the period is 100 ms, and the time-frequency resource A occupies 10 physical resource blocks (PRBs) in the frequency domain. After the base station configures the time-frequency resource A for the terminal, the MCS corresponding to the time-frequency resource A is 5, and the RI is 1. If the terminal does not receive the RRC message for updating the MCS or the RI or the time-frequency resource from the base station in the subsequent period, the terminal will use the MCS corresponding to the time-frequency resource A, i.e. 5, and the RI, i.e. 1, to perform data transmission on the configured time-frequency resource A.

[0143] Since the MCS defines how many useful bits can be transmitted per resource element (RE). The MCS depends on the signal quality in the wireless link, and a high-quality MCS can transmit more useful bits in a symbol, and a low-quality MCS transmits fewer bits in a symbol. It is assumed that the data amount or the requirement for delay reliability, etc. of the terminal when performing data transmission on the time-frequency resource A at T2 is different from that at T1, and the channel quality of the terminal at T2 may have changed compared with that at T1. For example, the channel quality at T1 is relatively poor, and the MCS configured by the base station for the terminal is relatively low, and the channel quality of the terminal changes at T2. At this time, a higher MCS can be used for data transmission. If the terminal continues to use MCS=5 and RI=1 to perform uplink data transmission on the time-frequency resource A at T2, it will not be able to better adapt to the current channel condition of the terminal.

[0144] If a dynamic scheduling mode is used, although it can be flexible according to the rapid change of service demand, but each time scheduling needs related control signaling, resource overhead is large, in addition, the uplink scheduling trigger of the base station side depends on the terminal reporting SR and BSR to the base station, if the uplink weak coverage, SR and BSR reporting may fail, so the uplink scheduling duration will be larger, the terminal uplink back packet speed will be affected, which is very unfriendly to low latency and large uplink service.

[0145] Therefore, a communication method is provided, which obtains first information, second information and third information of a first terminal, and then predicts a first transmission resource and corresponding one or more transmission parameters of the first terminal in a second time unit based on the first information, the second information and the third information of the first terminal. Then the first transmission resource and the value of the corresponding one or more transmission parameters are pre-configured to the first terminal through a first message, so that the first terminal can perform data transmission on the first transmission resource according to the transmission mode corresponding to the value of the one or more transmission parameters in the second time unit. Since the first transmission resource is pre-configured to the first terminal, the scheduling can be avoided and the latency can be reduced compared with the prior art. In addition, since the above information of the first terminal is used to predict the transmission resource and the value of the transmission parameter of the first terminal in the second time unit, the channel of the first terminal in the second time unit can be better adapted and matched, so that the data can be transmitted more efficiently, and the spectrum efficiency can be improved.

[0162] As shown in FIG. 6, FIG. 6 shows a flowchart of a communication method provided by the present application, which includes the following steps:

[0163] Step 601, obtaining first information, second information and third information of the first terminal.

[0164] For example, the first information is used to describe the configuration parameters, position, motion state and / or capability of the first terminal. The first information can be referred to as: the behavior state information of the first terminal.

[0165] The first information in the embodiments of the present application may, as an example, correspond to a first time unit, due to different motion states, positions, and configuration parameters and / or capabilities of the first terminal at different times. The first information is used to describe the configuration parameters, position, motion state and / or capability of the first terminal at the first time unit. By determining the configuration parameters, position, motion state and / or capability of the first terminal at the first time unit, the channel characteristics of the first terminal at a second time unit can be accurately predicted subsequently.

[0166] The first time unit may, for example, refer to a current time unit or a time unit before the current time unit, and the embodiments of the present application do not limit this.

[0167] For example, the position of the first terminal may, for example, include coordinates of the first terminal.

[0168] Optionally, the position of the first terminal may, for example, also indicate whether the first terminal is stationary or mobile.

[0169] For example, the motion state of the first terminal may, for example, include one or more of the following: a moving speed of the first terminal, a moving direction of the first terminal.

[0170] For example, the configuration parameters of the first terminal may, for example, include a number of antennas of the first terminal, a number of antenna ports, and a direction of the antenna.

[0171] For example, the first terminal may, for example, be an intelligent agent, and the position of the first terminal may, for example, refer to a position of an antenna of the first terminal.

[0172] For example, the capability of the first terminal may, for example, refer to a sending capability of the first terminal. For example, the sending capability may, for example, include a maximum transmission power of the first terminal.

[0173] For example, the second information may, for example, be used to reflect the channel characteristics of the first terminal. The second information may, for example, also be referred to as channel state information. The channel state information may, for example, include any one or more of the following: a user channel type (cdl etc), channel correlation, reference signal receiving power (RSRP), power delay profile (PDP), Doppler spectrum, angle delay spectrum, etc. The power delay profile may, for example, refer to a relationship between power and time delay of arrival of a signal received at a receiving end in a wireless channel.

[0174] Since the behavior state information of the first terminal at different times can be different, and the channel characteristics are usually related to the behavior state information of the first terminal such as the position and / or the moving speed of the first terminal, the channel characteristics of the first terminal can also change when the behavior state information of the first terminal such as the position and / or the moving speed of the first terminal changes. For example, the corresponding channel characteristics of the first terminal when the first terminal is moving can be different from the corresponding channel characteristics of the first terminal when the first terminal is stationary, and the corresponding channel characteristics of the first terminal can also be different when the first terminal is at different positions. Therefore, the access network device can obtain the second information of the first terminal under the first information, so as to fully reflect the channel characteristics of the first terminal at a certain position or at a certain moving speed, so that the channel characteristics of the first terminal corresponding to the second time unit predicted by combining the second information is closer to the actual channel characteristics of the first terminal at the second time unit, and the first transmission resource and the corresponding m transmission parameters predicted for the first terminal are more suitable for the channel characteristics of the first terminal at the second time unit.

[0175] The communication device is the access network device, which can obtain the second information corresponding to the first terminal at the first time unit to reflect the channel characteristics of the first terminal at the first time unit. In other words, the second information corresponds to the first time unit, and is used to reflect the channel characteristics of the first terminal under the first information at the first time unit. For example, the channel characteristics in the embodiments of the present application are used to reflect the channel quality of the first terminal.

[0176] The second information of the first terminal can be predicted based on the behavior state information of the first terminal (i.e., the behavior state information of the first terminal before the first time unit) and a channel characteristic prediction model, can be measured, or can be obtained from the first terminal, i.e., the first terminal reports the second information of the first terminal at the first time unit to the communication device. The embodiments of the present application do not limit this.

[0177] The above-mentioned channel characteristic prediction model can be an AI model or a neural network model. The input of the channel characteristic prediction model is the behavior state information of the first terminal before the first time unit, and the output is the second information corresponding to the first terminal at the first time unit.

[0178] The channel characteristic prediction model can be a model specific to the first terminal or a general model. The model specific to the first terminal can be a model trained based on historical behavior state information of the first terminal at different times and corresponding channel state information of the first terminal at any historical behavior state information. The channel characteristic prediction model can be configured in the communication device or the first terminal, or stored in a server, which is not limited in the embodiments of the present application. The second information of the first terminal at the first time unit can also be predicted by other devices (such as the first terminal or a server) and then sent to the communication device, which is not limited in the embodiments of the present application.

[0179] For example, the third information is used to reflect the first service requirement of the first terminal. For example, the first service requirement can refer to the service requirement of the first terminal at the second time unit. For example, the requirement of the amount of data to be transmitted, the time required for transmission, the start time of data transmission, the transmission rate requirement (such as 20 Mbps), the delay requirement (such as 15 ms), the reliability requirement (such as 99%), the current network jitter, and the remaining PDB determine the service requirement level.

[0180] The third information can be referred to as service characteristic information. For example, the service characteristic information can include periodic / aperiodic service characteristics, network load, jitter, historical service ID, and historical service characteristics.

[0181] Optionally, the first service requirement is also used to reflect the size of the data to be transmitted by the first terminal at the second time unit.

[0182] For example, the communication device can be an access network device of the first terminal. The first terminal can be one or more terminals accessed, which is not limited in the embodiments of the present application.

[0183] In step 602, the first transmission resource and m transmission parameters of the first terminal at the second time unit are predicted according to the first information, the second information, and the third information.

[0184] Wherein, m is an integer greater than or equal to 1. For example, m is 1, or 2, or 3. For example, the m transmission parameters can include any one or more of the following: MCS, TPC, precoding mode, and RI.

[0185] Wherein, the values of the m transmission parameters can be V1, V2, …, V m The m transmission parameters correspond to the first transmission resource, or it can also be considered that the m transmission parameters correspond to the second time unit. The second time unit is later than the first time unit.

[0186] It is worth mentioning that the m transmission parameters in the embodiments of the present application can include any one or more of the following: MCS, TPC, precoding method, and RI, and the m transmission parameters can also include other transmission parameters, which are not limited in the embodiments of the present application. The value of any transmission parameter is used to indicate a transmission mode. For example, taking the transmission parameter as MCS, the value of MCS can be an index value of MCS, so that the first terminal can query the modulation mode and target code rate indicated by the index value of MCS through the MCS index table to perform data transmission on the first transmission resource.

[0187] As an example, the content of the MCS table can be as shown in Table 1:

[0188] Table 1

[0189] For example, the first terminal has an MCS index table, which can be pre-defined by a protocol or configured for the first terminal by the access network device through signaling. As an example, the content of the MCS index table is shown in Table 4. In the table, each row has an index value, each index value corresponds to a set of modulation order and code rate, different modulation orders correspond to different modulation modes. For example, modulation order Q m = 2 corresponds to the QPSK modulation mode. Modulation order Q m = 4 corresponds to the 16QAM modulation mode. Modulation order Q m = 6 corresponds to the 64QAM modulation mode. Modulation order Q m = 8 corresponds to the 256QAM modulation mode.

[0190] For example, the first terminal can be predicted to use modulation order Q m = 2 and code rate 120 / 1024, i.e., the adopted modulation mode is QPSK, in the second time unit. Therefore, the fourth information can be used to indicate the index value of MCS as 2 to the first terminal.

[0191] The first transmission resource is used to guarantee the first service requirement.

[0192] For example, the first transmission resource used to guarantee the first service requirement can mean that the actual resource can be allocated to the first terminal for data transmission, but the allocated transmission resource can be completely consistent with the requirement of the first terminal, or there can be a difference between the requirement of the first terminal and the allocated transmission resource, but the allocated transmission resource can guarantee the service transmission.

[0193] It can be understood that the second time unit refers to a future time unit. The time unit involved in the embodiments of the present application can refer to any one or more of a time slot, a symbol, and a subframe, which is not limited in the embodiments of the present application.

[0194] In step 603, the first message is sent. Correspondingly, the first terminal receives the first message.

[0195] For example, the first message includes fourth information. The fourth information indicates the first transmission resource and the values of the m transmission parameters. The value of any one of the transmission parameters is used to indicate the strategy of the first terminal when performing data processing. For example, the value of MCS indicates the modulation mode adopted by the first terminal. For example, the values corresponding to TPC, RI, or precoding mode are used to indicate the TPC, RI, or precoding mode adopted by the first terminal when performing data transmission in the second time unit.

[0196] For example, the fourth information indicates the location of the first transmission resource. For example, the location of the first transmission resource can include the time domain location and the frequency domain location of the first transmission resource. The time domain location can be, for example, the time slot, the symbol, or the subframe corresponding to the first transmission resource in the time domain. The frequency domain location can be, for example, the subcarrier corresponding to the first transmission resource in the frequency domain.

[0197] Optionally, the fourth information is also used to indicate whether the first transmission resource allocated for the first terminal is used for uplink transmission or downlink transmission. For example, for uplink transmission, the fourth information is also used to indicate PUSCH.

[0198] For example, the fourth information includes the information of the first transmission resource and the information indicating the value of any one of the m transmission parameters. For example, the information of the first transmission resource can be the location of the first transmission resource. The information indicating the value of any one of the transmission parameters can be the index of the any one of the transmission parameters. For example, taking MCS as an example of a transmission parameter, the first terminal can generally be configured with an MCS index table, so that by indicating the index value of MCS to the first terminal, the first terminal can determine the indicated modulation mode by querying the MCS index table according to the index value of MCS.

[0199] As an example, the fourth information can comprise bunding information of the first transmission resource and values of the m transmission parameters. For example, the content of the fourth information can be: {{PUSCH t1 resource indication, f1 resource indication, MCS1, TPC1, Precoding1…}, {PUSCH t2 resource indication, f2 resource indication, MCS2, TPC2, Precoding2…}}. Wherein, t1 resource indication is used to indicate the time domain position of the transmission resource. f1 resource indication is used to indicate the frequency domain position of the transmission resource. MCS1 is used to represent the index value of the MCS determined by the communication device for the first terminal. TPC1 is used to represent the determined TPC. Precoding1 is used to represent the determined precoding mode, or the index of the precoding mode based on the codebook.

[0200] As an example, for the MCS, the modulation mode can be indicated to the first terminal by the index value. For the TPC or the RI or the precoding mode, the TPC or the RI or the precoding mode can be indicated to the first terminal by the bit, such as “00” representing the first precoding mode, “01” representing the second precoding mode, and the like. The embodiments of the present application are not limited thereto.

[0201] The fourth information further indicates that the first transmission resource corresponds to the periodic service or the aperiodic service.

[0202] As an example, the first message can further comprise: an MCS index table.

[0203] Optionally, in the embodiments of the present application, the first transmission resource and the values of the m transmission parameters are carried in the same message to indicate the association between the first transmission resource and the values of the m transmission parameters. Of course, the first transmission resource and the values of the m transmission parameters can also be located in different messages. At this time, the first transmission resource and the values of the m transmission parameters can correspond to the same parameter so as to facilitate the first terminal to determine that the first transmission resource and the values of the m transmission parameters are associated with each other.

[0204] The specific time-frequency resource indication mode is not limited, such as {StartOffset1, Slot length1, startRB1, NumRB1, period1} or {Startset1, Endset1, StartRB1, EndRB1, period1}. Wherein, period is optional, representing the periodic or aperiodic service. Wherein, StartOffset represents the start offset. Slot length represents the slot length. NumRB represents the number of RBs. StartRB represents the start RB. Startset represents the time domain start position. Endset represents the time domain end position. StartRB represents the start RB. EndRB represents the end RB.

[0205] As an example, the communication apparatus can send the first message before the second time unit. In this way, the first terminal can know the transmission resource and the corresponding transmission parameters allocated by the communication apparatus for the terminal in the second time unit in advance.

[0206] The RRC indication can be based on a bunding relationship, such as a chain relationship based on timeDomainAllocation or mcs, etc. The resource indication information can be as follows: rrc-ConfiguredUplinkGrant SEQUENCE{

[0207] {timeDomainAllocation, frequencyDomainAllocation, mcsAndTBS, Precoding, …}

[0208] The specific content can be as shown in Table 2, for example:

[0209] Table 2

[0210] Optionally, after the first terminal receives the first message, the first terminal can determine the first transmission resource allocated by the communication apparatus for the first terminal in the second time unit and the values of the m transmission parameters corresponding to the first transmission resource. Then, when the first terminal has a data transmission demand in the second time unit, the first terminal can perform data transmission on the first transmission resource according to the values of the m transmission parameters.

[0211] For example, taking the access network device of the communication apparatus as the first terminal as an example, if the first transmission resource allocated by the communication apparatus for the first terminal is used for uplink transmission, the first terminal can send uplink data to the communication apparatus on the first transmission resource according to the values of the m transmission parameters.

[0212] For example, taking the access network device of the communication apparatus as the first terminal as an example, if the first transmission resource allocated by the communication apparatus for the first terminal is used for downlink transmission, the first terminal can receive downlink data from the access network device on the first transmission resource according to the values of the m transmission parameters.

[0213] For example, taking the access network device of the communication apparatus as the first terminal as an example, if the first transmission resource allocated by the communication apparatus for the first terminal is used for sidelink transmission, the first terminal can transmit sidelink services on the first transmission resource according to the values of the m transmission parameters. For example, the first terminal can send sidelink services to the second terminal on the first transmission resource according to the values of the m transmission parameters.

[0214] The method for resource configuration provided in the embodiments of the present application comprises the following steps: obtaining first information, second information and third information of a first terminal; and predicting a first transmission resource and parameter values of m transmission parameters corresponding to the first transmission resource of the first terminal in a second time unit according to the first information, the second information and the third information. The first information is used to describe configuration parameters, positions, motion states and / or capabilities of the first terminal in a first time unit; the second information is used to reflect channel characteristics of the first terminal under the first information; and the third information is used to reflect first service requirements of the first terminal. Since the channel characteristics corresponding to the first terminal under different first information are different, the first transmission resource and the parameter values of the corresponding transmission parameters required by the first terminal in the second time unit can be predicted based on the above information corresponding to the first terminal in the first time unit, and the first transmission resource and the parameter values of the corresponding transmission parameters are configured for the first terminal in advance. In this way, the first transmission resource and the parameter values of the corresponding transmission parameters configured for the first terminal are more suitable for the channel characteristics of the first terminal in the second time unit, so that data can be transmitted efficiently. Compared with the scheduling mode in the prior art, the method can realize resource configuration through a scheduling-free mode.

[0215] In the embodiments of the present application, one or more of the first information, the second information and the third information of the first terminal can be obtained. In the case where the first information and the second information are obtained, the first transmission resource and V1, V2, …, Vm of the first terminal in the second time unit can be predicted based on the first information and the second information. m In the case where the first information and the third information are obtained, the first transmission resource and V1, V2, …, Vm of the first terminal in the second time unit can be predicted based on the first information and the third information. m In the case where the second information and the third information are obtained, the first transmission resource and V1, V2, …, Vm of the first terminal in the second time unit can be predicted based on the second information and the third information. m In the case where any one of the first information, the second information and the third information is obtained, the first transmission resource and V1, V2, …, Vm of the first terminal in the second time unit can be predicted based on the obtained any one of the information. m .

[0216] As an example, the channel state information of the first terminal can be obtained in the following ways:

[0217] Method 1: The first terminal reports one or more of the channel state information, the behavior state information and the service characteristic information of the first terminal.

[0218] Method 2: The channel state information of the first terminal is obtained through sensing.

[0219] Some statistical information can be obtained by sensing or ray chasing, so that the long-time information of the large-dimensional channel can be obtained. For example, the statistical channel information of each position can be estimated and predicted by using spatial correlation, and the spatial correlation of the channel information of different positions can be analyzed; the statistical channel information of different paths at different times or the same path at different times can be estimated and predicted by using time correlation, and the time correlation of the statistical channel information at different times can be analyzed; for the dynamic environment change characteristics in the service cell range, the corresponding channel change characteristics can also be obtained by using spatial correlation and time correlation.

[0220] Option 3: predicting one or more of the channel state information, the behavior state information and the first service demand of the first terminal at the first time unit based on the historical information of the first terminal, including the historical channel state information, the historical behavior state information and the service characteristic information.

[0221] For example, the service demand can be obtained according to the service characteristics, network characteristics and other parameter information of the first terminal. For example, the uplink service demand of the intelligent agent has regularity, such as the pick-and-drop robot, which has similar service characteristic regularity and service demand at a fixed time.

[0222] As a possible embodiment, the method can further include: the communication device obtaining fifth information. The fifth information is used to determine the available transmission resources, and the available transmission resources include the first transmission resources. In other words, the fifth information is used to indicate the current remaining transmission resources, i.e., the transmission resources allocated to other terminals.

[0223] Correspondingly, the above step 602 can be implemented in the following manner: predicting the values of the first transmission resources and the m transmission parameters of the first terminal at the second time unit, i.e., V1, V2, …, Vm, according to the first information, the second information and the third information, and the fifth information.

[0224] For example, the fifth information includes the scheduling strategy, the scheduling resources and the spectrum efficiency of the communication device.

[0225] For example, the scheduling resources can include the resources that can be scheduled in the time domain and the frequency domain. The spectrum efficiency can guide to adopt a scheduling mode with higher spectrum efficiency when predicting the transmission resources corresponding to the second transmission unit for the first terminal.

[0226] For example, the scheduling strategy can be a PF algorithm or a Round Robin algorithm.

[0227] In a possible embodiment of the present application, the first transmission resource and the values of the m transmission parameters are obtained by the first artificial intelligence (AI) model from the first information, the second information, and the third information. In other words, as shown in (a) of FIG. 8, the communication device can input the first information, the second information, and the third information into the first artificial intelligence (AI) model as input of the first artificial intelligence (AI) model, so as to obtain the first transmission resource and the values of the m transmission parameters by the first artificial intelligence (AI) model.

[0228] It can be understood that the first artificial intelligence (AI) model can be stored in the communication device, or can be obtained by the communication device from a network element in the core network or from a server, which is not limited in the present application. The first artificial intelligence (AI) model can be a general artificial intelligence (AI) model for predicting transmission resources and values of transmission parameters, or can be a first terminal-specific artificial intelligence (AI) model, which is not limited in the embodiments of the present application.

[0229] For example, the first artificial intelligence (AI) model can be trained by a base station or a terminal, or can be trained by other devices such as a network element in the core network or a server, which is not limited in the embodiments of the present application.

[0230] For example, the first artificial intelligence (AI) model includes two parts, i.e., a first AI sub-model and a second AI sub-model. The first AI sub-model is used to predict channel characteristics of the terminal at a future time unit. For example, the terminal / base station trains the first AI model based on input of the channel characteristics into the channel atlas. The input characteristics include channel characteristics of the terminal at a certain position and a moving speed, including RSRP, Doppler spectrum, channel between different antennas, and other information. The second AI sub-model is used to predict time-frequency resources of the terminal at a future time unit. For example, the terminal / base station can train the AI model based on identification of the service, i.e., service ID, service law characteristics (packet size, delay requirement, reliability requirement), server position, weather and network load, network jitter, and other parameters to obtain the second AI sub-model.

[0231] As an example, the first AI model can be obtained in the following manner.

[0232] For example, the terminal or the base station obtains the channel atlas. The terminal or the base station obtains the demand atlas.

[0233] As an example, the channel atlas is only an example, and other names can also be used, which is not limited in the embodiments of the present application. The purpose is to obtain information of the channel. The demand atlas is only a statement, and the purpose is to obtain information of the service characteristics.

[0234] As an example, the terminal or base station acquires the channel map by constructing the channel map according to the geographical position G(x, y), the channel environment characteristics, the moving speed of the terminal, and other parameter information, to represent the channel H.

[0235] For example, the base station can obtain the following large-scale information of the user according to the channel measured by the UE at different positions: RSRP, channel type (K factor, whether LoS path), PDP spectrum (delay spread), channel correlation, and other channel characteristics. Different channels can be mapped to different CQI and RI values. It should be understood that the base station serves as a unified scheduling center and service center, and can acquire the channel characteristics of the UE at different positions.

[0236] For the semi-static environmental change characteristics in the service cell range, the base station can acquire some statistical information by sensing or ray chasing, so as to acquire the long-time information of the large-dimensional channel.

[0237] Some possible methods are given in the present application:

[0238] Utilize spatial correlation: 1. Select multiple test paths in the coverage range of the base station 2. Measure the channel at a certain distance on each test path 3. Offline estimate the statistical channel information at each position, and analyze the spatial correlation of the channel information at different positions.

[0239] Time correlation analysis: 1. Select multiple test paths in the coverage range of the base station 2. Measure the channel data at different seasons on each test path 3. Offline estimate the statistical channel information at different times on different paths, and analyze the time correlation of the statistical channel information at different times.

[0240] For the dynamic environmental change characteristics in the service cell range, the base station can also utilize spatial correlation and time correlation to obtain the corresponding channel change characteristics.

[0241] In principle, for a moving terminal, especially a vehicle, the moving distance is limited in a short time, and the vehicle speed is relatively constant, and the channel also has certain channel correlation in time. In addition, the mobility of the vehicle will cause the channel to have a Doppler frequency offset, so if the moving speed of the vehicle can be known, the Doppler frequency offset of the channel can be compensated, so as to obtain a more accurate channel. As shown in (a) of FIG. 7, UE1 moves from position 1 to position 2, and the channel between the two positions has correlation.

[0242] In principle, for mobile terminals, especially vehicles, the driving track of the vehicles is predictable in space, and the channels of different vehicles driving to the same location are correlated, so for different vehicles in the same lane, the channel of the preceding vehicle can be used as a reference for the channel quality information of the current vehicle at future time. As shown in (b) of FIG. 7, UE2 and UE1 move to the same location at time t-1 and t respectively, and then for different terminals at the location, the channel between them is also correlated.

[0243] As an example, the terminal or the base station can obtain a demand map according to parameter information such as service characteristics, network characteristics, and the like.

[0244] For example, the base station can determine the demand level of the service according to service characteristics such as 4MB, 100ms@99%, current network jitter, and remaining PDB.

[0245] It should be understood that the experience of the end user is mainly reflected in the continuity of the service, for example, when the channel state is good, but if the service is a high-reliability, low-latency large packet service, if not enough resources are given, the continuity and integrity of the service cannot be guaranteed, resulting in poor experience of the terminal; in addition, when the network is congested or the jitter is large, if the scheduling strategy such as round robin is still used, it may result in insufficient retransmission opportunities, and therefore the base station may need to adopt a conservative strategy such as low MCS, low RANK, etc. when transmitting, in order to avoid retransmission and to prevent the packet transmission delay from exceeding the PDB.

[0246] For parameters such as network jitter, the base station can make a prediction through long-term statistics or according to the arrival of packets.

[0247] Combining the above two schemes, as shown in (b) of FIG. 8, the base station can use the first AI model to predict the subsequent transmission behavior of the first terminal in advance according to the channel characteristics and the demand characteristics, and determine the adaptive time-frequency domain resources and transmission mode, etc.

[0248] In a possible embodiment of the present application, in the case where the communication apparatus acquires the fifth information, the communication apparatus can take the first information, the second information, the third information, and the fifth information as inputs of the first artificial intelligence (AI) model, to obtain the first transmission resource and the values of the m transmission parameters, i.e., V1, V2, …, Vm, through the first artificial intelligence (AI) model. m .

[0249] Suppose the service demand of the first terminal in the second time unit is a transmission rate of 20Mbps, a latency of 15ms, and a reliability of 99%, then for the first terminal, the appropriate MCS, TPC, RI, and other transmission parameters can be selected according to the service demand of the first terminal in the second time unit and the predicted channel characteristics of the first terminal in the second time unit.

[0250] In a possible implementation, the first message can be an RRC message. It can be understood that the RRC message can include other parameters in the existing RRC message in addition to the information of the first transmission resource, the MCS, the TPC, the RI, and other transmission parameters, and the embodiments of the present application do not limit this.

[0251] When the first condition is met, the first message is sent to the first terminal. For example, the first condition includes any one or more of the following: a preset sending period is reached, the first terminal is about to access the access network device, or the service of the first terminal changes.

[0252] As an example, the first information can be periodically issued or triggered by an RRC message. Triggered issuance can refer to determining that the first terminal is about to access or the service of the first terminal changes (which can be based on historical rules, UE reporting requests, etc.), UE switching, etc.

[0253] For example, taking the first terminal as an intelligent agent, due to the regularity of the intelligent agent service, the access network device can predict in advance that the first terminal is about to access and the data transmission time point after access based on the service characteristics of the intelligent agent.

[0254] After the first transmission resource and / or the values of the m transmission parameters are allocated to the first terminal, if it is determined that a second terminal is about to access, the corresponding time-frequency resource is usually allocated to the second terminal based on the service demand of the second terminal to ensure data transmission of the second terminal. At this time, in order to avoid conflicts between the time-frequency resource of the first terminal and the time-frequency resource of the second terminal, etc., the communication device will re-allocate the time-frequency resource to the first terminal in the remaining time-frequency resource, or according to the re-reported channel state information and / or demand information of the first terminal, it is determined that the channel state or service demand of the first terminal in the second time unit changes, then the communication device can re-allocate the time-frequency resource to the first terminal in the remaining time-frequency resource. Therefore, in a possible embodiment of the present application, after step 603, as shown in FIG. 9, the method can further include:

[0255] Step 604, re-determining the second transmission resource corresponding to the first terminal in the second time unit and the updated values of the m transmission parameters.

[0256] Step 605, sending a second message to the first terminal, the second message including ninth information. The ninth information is used to indicate the updated values of the second transmission resource and / or the m transmission parameters.

[0257] For example, the second message can be a DCI, or an RRC reconfiguration message or an RRC message. In other words, the updated transport resource and / or the updated values of the m transport parameters corresponding to the second time unit can be dynamically indicated by the DCI.

[0258] It is worth noting that the first terminal can or can not change the transport resource corresponding to the second time unit, and the values of the m transport parameters can or can not change. In the case where the first terminal does not change the transport resource corresponding to the second time unit, i.e., the second transport resource is considered to be the first transport resource, only the values of the m transport parameters change, the ninth information can be used to indicate the updated values of the m transport parameters, so that the first terminal can associate the updated values of the m transport parameters with the first transport resource, i.e., determine to use the updated values of the m transport parameters for data transmission on the first transport resource. Or the ninth information can be used to indicate the updated values of the m transport parameters and the second transport resource. Similarly, in the case where the first terminal updates the transport resource corresponding to the second time unit from the first transport resource to the second transport resource, but the values of the m transport parameters do not change, since the first terminal already has the values of the m transport parameters corresponding to the second time unit, the ninth information can indicate the second transport resource, so that the first terminal can determine the values of the m transport parameters corresponding to the second transport resource.

[0259] As an example, the re-determination of the second transport resource corresponding to the second time unit for the first terminal and the updated values of the m transport parameters can be implemented in the following way:

[0260] Obtain the sixth information, the seventh information and the eighth information of the first terminal, the sixth information is used to describe the configuration parameters, the position, the motion state and / or the capability of the first terminal in the third time unit; the seventh information is used to reflect the channel characteristics of the first terminal under the sixth information, and the eighth information is used to reflect the second service requirement of the first terminal, the third time unit is later than the first time unit and earlier than the second time unit.

[0261] According to the sixth information, the seventh information and the eighth information, predict the second transport resource and V1', V2', …, V m ’ of the first terminal in the second time unit. m V1', V2', …, V

[0262] For example, the channel state of a same terminal is different at different locations and / or different moving speeds. Assuming that the first terminal is located at location A at T1 time and moving at speed X1, the first information obtained can include the coordinates of the first terminal at location A and the moving speed X1. Optionally, channel feature 1 of the first terminal at location A and moving at speed X1 can be obtained. Then, time-frequency resource 1 and the index value 1 of the MCS of the first terminal at T2 time can be predicted based on the channel feature 1 and the first service requirement. For example, the time-frequency resource 1 is located at time slot 1 and corresponds to subcarrier 1. With the movement of the first terminal, the location and / or the moving speed of the first terminal changes, for example, the location of the first terminal changes to location B, even if the moving speed does not change, then the channel feature of the first terminal at this time can change, and therefore the channel feature 2 of the first terminal at location B and moving at speed X1 can be re-obtained. Then, time-frequency resource 2 and the index value 2 of the MCS of the first terminal at T2 time can be predicted based on the channel feature 2 and the first service requirement. It can be understood that the time-frequency resource 2 and the time-frequency resource 1 can be a same time-frequency resource, but the index value 1 of the MCS and the index value 2 of the MCS are different. Or the time-frequency resource 2 and the time-frequency resource 1 can be different, and the index value 1 of the MCS and the index value 2 of the MCS are the same or different.

[0263] It can be understood that the time-frequency resource 2 and the time-frequency resource 1 can be different can mean that the time domain positions of the time-frequency resource 2 and the time-frequency resource 1 are the same, but the frequency domain positions are different. For example, the time-frequency resource 2 and the time-frequency resource 1 both correspond to time slot 1, but the time-frequency resource 2 corresponds to subcarrier 1, and the time-frequency resource 1 corresponds to subcarrier 2.

[0264] The time-frequency resource 2 and the time-frequency resource 1 can be different can mean that the time domain positions of the time-frequency resource 2 and the time-frequency resource 1 are different, but the frequency domain positions are the same. For example, the time-frequency resource 2 and the time-frequency resource 1 both correspond to subcarrier 1, but the time-frequency resource 2 corresponds to time slot 1, and the time-frequency resource 1 corresponds to time slot 2.

[0265] Or the time domain positions of the time-frequency resource 2 and the time-frequency resource 1 are not the same, and the frequency domain positions are different.

[0266] In a possible embodiment of the present application, the updated values of the m transmission parameters are determined according to the updated channel state of the first terminal at a second time unit, and the updated channel state of the second time unit is predicted according to the seventh information and the eighth information.

[0267] In a possible implementation of the present application, after the first terminal acquires the first message, the first terminal can cache the first transmission resource corresponding to the second time unit and the values of the m transmission parameters, as shown in FIG. 9. When the first terminal needs to perform data transmission in the second time unit later, the first terminal can perform data transmission on the first transmission resource according to the values of the m transmission parameters.

[0268] In a possible implementation of the present application, after the first terminal acquires the first message, if the first terminal is allocated the updated values of the m transmission parameters corresponding to the second time unit and the second transmission resource, the second message can be sent to the first terminal, as shown in FIG. 9. The second message includes ninth information, and the ninth information is used to indicate the updated values of the m transmission parameters corresponding to the second time unit and the second transmission resource. Accordingly, the first terminal updates the values of the m transmission parameters corresponding to the second time unit and the transmission resource to the updated values of the m transmission parameters and the second transmission resource according to the second message.

[0269] In a possible implementation of the present application, after the first terminal acquires the first message or the second message, if the first terminal has no data transmission requirement temporarily, the first terminal can maintain the allocated values of the m transmission parameters and the first transmission resource, or maintain the updated values of the m transmission parameters and the second transmission resource, as shown in FIG. 9.

[0270] In the scheme provided by the embodiments of the present application, the first transmission resource and the corresponding m transmission parameters in the second time unit are predicted for the first terminal in advance according to the third information of the first terminal and the first information and the second information of the first terminal corresponding to the first time unit, so that the first terminal can directly use the m transmission parameters to perform uplink transmission in the second time unit, without the need to acquire time-frequency resources through scheduling. Compared with the dynamic scheduling mode, the scheme can reduce the delay. In addition, compared with the semi-static scheduling mode in the prior art, the time-frequency resources and the m transmission parameters allocated to the first terminal by the scheme can better adapt to the channel characteristics of the first terminal in the second time unit.

[0271] As shown in FIG. 10, for the existing resource scheduling method, there is no prediction function, and the base station allocates corresponding time-frequency resources based on the service demand of the terminal of the existing cell. For example, as shown in (a) of FIG. 10, the base station allocates periodic time-frequency resource 1 to terminal 1, periodic time-frequency resource 2 to terminal 2, and periodic time-frequency resource 3 to terminal 3. Assuming that after a new terminal 4 accesses in time slot 2, the base station will allocate resources based on the remaining available resources, but after terminal 4 accesses, the time domain resource allocated by the base station to terminal 4 may overlap with the time-frequency resource 3 allocated by the base station to terminal 3 in the time domain, which may cause low overall resource utilization efficiency. In the present application, the base station allocates periodic time-frequency resource 1 to terminal 1, periodic time-frequency resource 2 to terminal 2, and periodic time-frequency resource 3 to terminal 3 by prediction, as shown in (b) of FIG. 10. Assuming that the base station predicts that a new terminal 4 will access in time slot 2 and terminal 4 has data transmission demand in time slot 1, taking terminal 4 as an agent, if the service of the agent has regularity, such as periodically sending uplink data, the base station can predict in advance that terminal 4 will access in a certain time slot and perform data transmission. Then the base station can allocate time-frequency resource 4 to terminal 4 in time slot 1 based on the service demand and channel state information of terminal 4. The time-frequency resource 4 corresponds to time slot 1 in the time domain. Then after terminal 4 accesses, data transmission can be performed on time-frequency resource 4 to avoid the base station allocating time-frequency resource to terminal 4 through scheduling, that is, time-frequency resource 4 can be regarded as a scheduling-free resource, thereby reducing the time delay. It can be understood that, compared with (a) of FIG. 10, in (b) of FIG. 10, the base station considers terminal 4 when allocating time-frequency resources to terminals 1-3, so that the base station can allocate time-frequency resources to terminals 1-4 more reasonably and flexibly to avoid the time-frequency resources of terminals 1-4 colliding or colliding in the time domain, thereby enabling more efficient system resource allocation.

[0272] As shown in FIG. 11, FIG. 11 shows a resource allocation diagram in which the base station configures time-frequency resources and transmission parameters for terminals in a semi-static manner. As shown in (a) of FIG. 11, the base station can configure one or more time-frequency resources for the terminal through RRC. The multiple time-frequency resources can be periodic time-frequency resources. As shown in (a) of FIG. 11, in the case of configuring resources for terminals in a semi-static manner, the time-frequency resources correspond to the same MCS and TPC in each period, such as a time-frequency resource corresponding to MCS=6 and TPC1 in each period, and another time-frequency resource corresponding to MCS=10 and TPC2 in each period.

[0273] As shown in (b) of FIG. 11, the base station can dynamically configure one or more time-frequency resources for the terminal through DCI, and the time-frequency resources can be periodic time-frequency resources. Compared with the semi-static manner shown in (a) of FIG. 11, the base station can dynamically indicate the MCS and TPC corresponding to each time-frequency resource, for example, the base station can indicate, through DCI, that a time-frequency resource corresponds to MCS=6 and TPC1 in time unit 1, and indicate, through DCI, that the time-frequency resource corresponds to MCS=8 and TPC2 in the next time unit 3, and further indicate, through DCI, that the time-frequency resource corresponds to MCS=5 and TPC3 in the next time unit 3.

[0274] As shown in (c) of FIG. 11, the base station can predict, for the terminal, a time-frequency resource in a certain time unit and the MCS, TPC and precoding manner corresponding to the time-frequency resource by using the method provided in the embodiments of the present application. The time-frequency resource can be a periodic resource. Through the prediction method, the terminal can have different time-frequency resources, MCS, TPC and precoding manners in different channels, for example, the base station can determine, through the prediction method, that terminal 1 corresponds to time-frequency resource A in time unit 1, and that the channel state of terminal 1 in time unit 1 is adapted to MCS=6, TPC1 and precoding manner 1. Assuming that the service requirement of the first terminal at this time is 10 Mbps, 10 ms and 99%, the base station can indicate, through RRC message / signaling, that time-frequency resource A corresponds to MCS=6, TPC1 and precoding manner 1 in time unit 1. Assuming that the service requirement of terminal 1 changes subsequently, for example, 20 Mbps, 15 ms and 99%, and the channel state of terminal 1 in time unit 3 changes, in order to better adapt to the channel state and service requirement corresponding to time unit 3, the base station can update, through RRC message, time-frequency resource A for terminal 1, and set the MCS corresponding to time unit 3 to 8, update TPC to TPC3 and update the precoding manner to precoding manner 3.
