[0073] In order to make the above purposes, features and advantages of the present application more apparent, clear and easy to understand, the technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings and in conjunction with the specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of the present application.

[0074] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application, and are not used to limit the present application.

[0075] In order to better understand the technical solutions of the present application, the specific embodiments will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0076] Currently, in a wireless communication system, control information carries the scheduling function of the entire communication system. For example, in the LTE (Long Term Evolution) system and the NR (New Radio) system, the multiple downlink control information issued by the base station (management station) under the same subframe is respectively encoded and modulated. When the terminal station receives, it needs to try to demodulate and decode multiple control information under different aggregation levels to finally obtain the control information it needs to receive; in the EUHT (Enhanced Ultra High Throughput) system, the multiple downlink control information issued by the management station under the same radio frame is respectively encoded and modulated. When the terminal station receives, it needs to decode each control information to determine whether it is the control information it needs to receive; in the WIFI6 (sixth generation wireless network technology) system, the downlink scheduling information and the uplink scheduling information are in different trigger frames, and the device needs to receive and decode respectively to determine its uplink and downlink scheduling information. In the existing various wireless technologies, the control information from multiple users through multiple terminal stations, or the control information of uplink scheduling and downlink scheduling, is respectively encoded and modulated; the terminal station needs to decode and try multiple times when receiving, increasing the processing delay. At present, in the wireless system of the industrial scene with higher real-time requirement, there is an urgent need for a transmission scheme that can enable the device to receive its own control information faster.

[0077] In order to overcome the technical defects existing in the prior art, the embodiments of the present application provide a control information transmission method applied to a management station, referring to FIG. 1, which is a flowchart of the control information transmission method applied to the management station, in embodiment one, the control information transmission method comprises:

[0078] Step S10, generating a control information frame according to the control information combination of at least one terminal station;

[0079] The management station and the terminal station in the embodiments of the present application are applied to a high real-time and high reliable wireless communication system. The wireless communication system supports different wireless frame lengths, meets different service cycle scenarios, and FIG. 2 is a schematic diagram of a wireless frame structure with a frame length of 1 ms. Control information is carried through a control information frame (CIF), and the CIF occupies a configurable number of symbols. Downlink data is transmitted on a DTCH (Downlink Transport Channel) channel, and uplink data is transmitted on a UTCH (Uplink Transport Channel) channel. In addition, in FIG. 2, DSS (Downlink Synchronization Signal) refers to a downlink synchronization signal, DRS (Downlink Reference Signal) refers to a downlink demodulation reference signal, GP (Guard Period) refers to a guard period slot, USS (Uplink Synchronization Signal) refers to an uplink synchronization signal, and URS (Uplink Reference Signal) refers to an uplink demodulation reference signal.

[0080] Specifically, referring to FIG. 3, the wireless network device in the wireless communication system at least includes a wireless network center node and an edge node of the wireless network. In FIG. 3, MS (Management Station) is used to represent the wireless network center node, which is the convergence center of the wireless network and has the management capability of the wireless network, such as an LTE base station, an NR base station, an AP (Access point) of WiFi, etc. In FIG. 3, TS (Terminal Station) is used to represent the edge node of the wireless network, which is the terminal node of the wireless network and accepts the network configuration management of the MS and is connected with a driving device. It can be understood that the technical solution of the embodiments of the present application can be applied to wireless network scenarios of various topologies, such as that the TS can be a single node, the TS can be a node in a star network, the TS is a node in a ring network, or the TS is a node in a linear network, etc., which are not limited herein.

[0081] In step S10, the wireless station MS combines the control information from one or more terminal stations together to generate a control information frame for carrying the control information, wherein each terminal station can correspond to a user, and different control information from one or more users through the terminal stations is combined together to obtain one control information frame, which can be one or more. When the number of terminals is one, the control information of multiple time slots corresponding to the terminal can be combined, or the control information of multiple time slots can be uniformly scheduled to improve the scheduling efficiency. The control information of each terminal station is sequentially distributed in the combined control information frame, and the control information includes the terminal station identifier of the target device representing the transmission of the control information, and the terminal station identifier of each terminal station TS is different. In the control information frame, one or more terminal station identifiers are included, which can be used by the terminal station to determine which control information is sent to itself and which can be discarded after the control information frame is parsed.

[0082] In step S20, the wireless signal corresponding to the control information frame is transmitted to the terminal station, so that the terminal station transmits data according to the communication resource corresponding to the terminal station identifier and the control information in the control information frame.

[0083] The control information is used to indicate whether the terminal station needs to transmit data, and also carries detailed information of the time-frequency domain resource and the modulation and coding rate involved in the transmission data.

[0084] After the control information frame is determined, the CRC (Cyclic Redundancy Check, cyclic redundancy check) check code corresponding to each control information frame is generated, and then encoded, modulated and mapped to the channel to transmit the corresponding wireless signal. After the terminal station in the signal coverage range of the management station receives the wireless signal, the corresponding control information frame can be read after the wireless signal is demodulated and decoded and the CRC check code is successfully checked, and the terminal station identifier of each control information is compared to screen out the control information matching the terminal station identifier pre-buffered in the system of the terminal station and map it to the wireless resource (channel) of the terminal station, and transmit data to the management station. As for the control information that does not match the terminal station identifier, it is directly discarded and not processed.

[0085] The technical scheme of the embodiment of the present application can combine the control information of one or more terminal stations together to obtain a corresponding control information frame, and then perform wireless signal transmission. Compared with separately sending the control information of each terminal station in different control information frames in batches, the complexity of the control information is effectively reduced, and the time delay is reduced. The terminal station can identify and select the control information that needs to be received according to the terminal station identifier of each control information in the control information frame, and then transmit data to the management station based on the corresponding communication resource in the control information. In summary, the control information transmission method of the technical scheme of the embodiment of the present application can support the management station to schedule the control information of multiple terminal stations or the multiple control information of one terminal station at one time, thereby greatly improving the scheduling efficiency of the control information.

[0086] In an embodiment, the control information frame includes a first control information frame, and the step of generating the control information frame according to the control information of at least one terminal station includes:

[0087] In step S11, the control information of each terminal station is combined in sequence to obtain a first control information frame.

[0088] In the control information, at least the control information type, the terminal station identifier, the time domain allocation indication information, the frequency domain allocation indication information, and the communication configuration information are included.

[0089] In the embodiment of the present application, the control information is divided into five parts, including the control information type, the terminal station identifier, the time domain allocation indication information, the frequency domain allocation indication information, and the communication configuration information, for example, by combining the control information of multiple terminal stations. The control information type (Type) can be used to represent the type of the control information and the length of the control information. The terminal station identifier (TSID, Terminal Station Identity document) is used to uniquely identify the terminal station. The time domain allocation indication information can include the radio frame offset and the time slot number. The "frame offset" is used to represent the offset of the allocated time domain resource from the radio frame in which the CIF is located. Specifically, the value of the frame offset is related to the business cycle in the industrial scene, the radio frame length, the system software and hardware processing capability, the network deployment, and other factors. The "time slot number" represents the time slot number in a radio frame. Taking the time slot as the scheduling unit in the time domain can facilitate the support of the time domain repeated transmission of industrial scene level data and guarantee the reliability of the scene level industrial data. The frequency domain allocation indication information is used to allocate resources in the frequency domain in units of resource blocks. Increasing the allocation resource of high real-time and high-reliable industrial data can increase the utilization rate of the spectrum after the resource and the throughput rate of the system. The communication configuration information represents other information that needs to be obtained by the terminal station, such as the modulation level, the coding rate, the number of antenna streams, the precoding matrix, the transmission mode mechanism indication, the power control field, the channel state information reporting indication, and the like. One or more of the above information can be selected and recorded in the communication configuration information according to the specific needs of the control information.

[0090] For example, referring to FIG. 4, the first control information frame includes 0-n control information and a CRC check code, each of the control information includes five parts, i.e., A (corresponding to the control information type), B (corresponding to the terminal station identifier), C (corresponding to the time domain allocation indication information), D (corresponding to the frequency domain allocation indication information), and E (corresponding to the communication configuration information), and is distributed in a centralized manner.

[0091] Based on the first control information frame, the control information of multiple terminal stations or time slots can be scheduled at one time, the scheduling efficiency is effectively improved, the processing time delay after receiving by the terminal station is greatly reduced compared with the traditional batch scheduling mode, and the real-time performance and reliability of the wireless communication system are improved.

[0092] Further, in an embodiment, the step of combining the control information of each terminal station in sequence to obtain the first control information frame includes:

[0093] Step S111, combining the control information based on the scheduling priority order of each control information to obtain the first control information frame; or,

[0094] Step S112, combining the control information based on the order of the terminal station identifier in each control information to obtain the first control information frame.

[0095] The embodiments of the present application provide two different sorting methods for the combination process of the control information.

[0096] One is to sort the control information based on the scheduling priority order, so that the first control information frame obtained is parsed by the terminal station in the order of the scheduling priority, which meets the scheduling priority requirement of the control information.

[0097] The second is based on the order of the terminal station identifier, for example, the terminal station identifier is in the form of multiple digits or a combination of digits and letters, and can be arranged in the order from small to large. When the terminal station receiving the first control information frame compares the terminal station identifier, if the terminal station identifier pre-buffered by itself is smaller than the terminal station identifier of the first control information, it is indicated that the terminal station identifiers of the subsequent other terminal stations are all greater than the terminal station identifier of the terminal station itself, and the comparison can be stopped and the first control information frame can be directly discarded, thereby saving the calculation resources and improving the processing efficiency.

[0098] In another embodiment, the control information frame includes a second control information frame and a third control information frame, and the step of combining the control information of at least one terminal station to generate a control information frame includes:

[0099] Step S12, combining the terminal station identifier in the control information of each terminal station in sequence to obtain the second control information frame.

[0100] Step S13, combining other information of each control information to obtain a third control information frame, wherein the other information at least includes control information type, time domain allocation indication information, frequency domain allocation indication information and communication configuration information, and the other information of the same control information is centrally distributed.

[0101] The embodiment of the present application further provides a method for generating a control information frame, which specifically carries terminal station identification and other control information in control information through two control information frames, i.e., the control information frame is composed of a second control information frame and a third control information frame.

[0102] Exemplarily, referring to FIG. 5, the MS maps control information of multiple terminal stations into two parts: a second control information frame CIF-I is used to carry B (corresponding to terminal station identification) part of the control information of the multiple terminal stations, and a third control information frame CIF-II carries other information of the control information of the multiple terminal stations, wherein the other information includes A (corresponding to control information type), C (corresponding to time domain allocation indication information), D (corresponding to frequency domain allocation indication information) and E (corresponding to communication configuration information); the combination order of the control information of the multiple terminal stations in CIF-I and CIF-II is consistent, and CIF-I and CIF-II respectively generate corresponding CRC check codes, and are respectively encoded and modulated before being mapped. It should be noted that in the third control information frame, the other information (A, C, D, E) of each control information is centrally distributed, as shown in FIG. 5, A0, C0, D0 and E0 belong to the same control information.

[0103] Different from the first control information frame, the terminal station identification in the embodiment of the present application is separately generated into a second control information frame, so that the terminal station can first receive a wireless signal corresponding to the second control information frame to analyze, and then acquire corresponding control information in the third control information frame after matching a terminal station identification matching the terminal station identification of itself, and if a consistent terminal station identification cannot be matched, the terminal station can not perform the processes of demodulating, decoding and CRC checking on the wireless signal corresponding to the third control information frame, thereby saving computing resources and communication resources to a certain extent.

[0104] In addition, the control information ordering in the second control information frame and the third control information frame can follow the ordering method provided in step S111 or step S112, which will not be described herein.

[0105] In another embodiment, the control information frame includes a fourth control information frame and a fifth control information frame, and the step of generating the control information frame according to the combination of the control information of at least one terminal station includes:

[0106] Step S14, combining the control information type and the terminal station identifier in the control information of each terminal station in sequence to obtain a fourth control information frame, and the control information type and the terminal station identifier of the same control information are centrally distributed;

[0107] Step S15, combining other information in each control information to obtain a fifth control information frame, wherein the other information at least includes time domain allocation indication information, frequency domain allocation indication information and communication configuration information, and the other information of the same control information is centrally distributed.

[0108] Similar to the previous embodiment, the embodiment of the application also divides the control information of each terminal station into two different control information frames for mapping, the difference is that the fourth control information frame in the embodiment of the application includes the control information type and the terminal station identifier, and in addition, the control information type is also used to represent the length of the control information.

[0109] Exemplarily, referring to FIG. 6, the MS maps the control information of multiple terminal stations into two parts: the fourth control information frame CIF-I is used to carry the A (corresponding to the control information type) part and the B (corresponding to the terminal station identifier) part of the control information of multiple terminal stations, and the fifth control information frame CIF-II carries other information of the control information of multiple terminals, and the other information includes C (corresponding to the time domain allocation indication information), D (corresponding to the frequency domain allocation indication information) and E (corresponding to the communication configuration information); the combination order of the control information of multiple terminal stations in CIF-I and CIF-II is consistent, and CIF-I and CIF-II respectively generate corresponding CRC check codes, and are respectively encoded and modulated before being mapped. It should be noted that in the fifth control information frame, the other information (C, D, E) of the same control information is centrally distributed, as shown in FIG. 5, C0, D0 and E0 belong to the same control information.

[0110] After receiving and analyzing the fourth control information frame at the terminal station, the position of the corresponding other control information in the fifth control information frame can be directly calculated and determined according to the control information type in the fourth control information frame after comparing to the consistent terminal station identifier. Specifically, since the control information type is used to represent the length of the control information, the starting point of the corresponding control information position in the fifth control information frame can be calculated according to the sum of the lengths corresponding to the control information types before the current control information type in the fourth control information frame, and the terminal point of the corresponding control information position can be calculated based on the length corresponding to the current control information type, so as to obtain the other part (including C, D and E) of the control information sent to the terminal station, which can also achieve certain calculation resource and communication resource saving effect.

[0111] In addition, the control information in the fourth control information frame and the fifth control information frame can be sorted according to the sorting method provided in step S111 or step S112, which will not be described herein.

[0112] In an embodiment, the control information transmission method applied to the management station can support scheduling one time slot (corresponding to one control information) for one or more terminal stations. For example, referring to FIG. 7, when one time slot is scheduled for one terminal station, any one of the above steps S11, steps S12 to S13, or steps S14 to S15 can be adopted to generate the corresponding control information frame.

[0113] In an embodiment, based on any one of the above steps S11, steps S12 to S13, or steps S14 to S15, the control information transmission method applied to the management station can support scheduling multiple continuous time slots at one time. The control information type is used to represent the number of continuous time slots scheduled, and the time domain allocation indication information includes the time slot number corresponding to the first time slot. In this embodiment, the control information type corresponds to the number of continuous time slots, and each number of continuous time slots belongs to one control information type. For example, the number of continuous time slots of one control information type is 2, and the number of continuous time slots of another control information type is 3.

[0114] In another embodiment, the control information type can also represent the number of non-continuous time slots scheduled, and the time domain allocation indication information includes the time slot number of each non-continuous time slot. For example, the time slot number includes 1, 3, 4, 6, and 7, and the number of non-continuous time slots corresponding to the time slot number is 5.

[0115] The technical solution of the embodiment of the present application can be applied to a scenario in which a terminal station has a large amount of data to be transmitted and has wireless resources, or the terminal station needs to perform multiple repeated transmissions in a short time. Referring to FIG. 8, when the number of terminal stations of the control information frame is 1, the control information type (i.e., the control information type in the embodiment) and the number of continuous time slots scheduled are indicated by part A of the control information frame in this case, and the time slot number in part C is used to represent the first time slot in the continuous multiple time slots scheduled.

[0116] Compared with the conventional method of transmitting multiple control information in batches, the embodiment of the present application maps multiple continuous time slots in the form of one control information frame, which effectively improves the scheduling efficiency of the wireless communication system and improves the real-time performance of information transmission.

[0117] In an embodiment, based on any one of the packet assembly manners in the above step S11, step S12 to step S13, or step S14 to step S15, the control information transmission method applied to the management station can support one or more terminal stations to schedule one downlink time slot and one uplink time slot in a radio frame at one time. The control information frame includes control information corresponding to the uplink time slot and the downlink time slot in a single radio frame, and the time domain allocation indication information includes time slot numbers (for example, time slot #1, time slot #2) corresponding to the uplink time slot and the downlink time slot respectively.

[0118] The technical solution of the embodiment of the present application can be applied to a scenario in which the MS issues to the terminal station and the terminal station needs to report data at the same time, for example, downlink data of a certain TS, and the TS1 needs to report channel state information, for example, downlink and uplink scheduling, and a certain TS is polled at the same time. Specifically, referring to FIG. 9, when the number of terminal stations in the control information frame is 1, the embodiment of the present application can support transmission of uplink and downlink data scheduling information in one control information frame. Wherein, the same field parameters of the uplink and downlink data scheduling information can be represented by one field, for example, terminal station identifier B; for the fields that are contained but have different parameters, two fields are used to represent them respectively, for example, time slot numbers in part C; the terminal station identifies the type of control information (that is, the control information type of the embodiment) through the control information format in part A.

[0119] The embodiment of the present application can also transmit the uplink and downlink scheduling information in two control information, without merging the same content, that is, the uplink and downlink scheduling information is regarded as control information A0-E0 and A1-E1 of different terminal stations, and only the same terminal station identifier B0 is used, and the packet assembly manner of the control information frame is shown in FIG. 10, and there are three different control information frame generation manners, which correspond to step S11, step S12 to step S13, or step S14 to step S15 respectively.

[0120] Compared with the traditional transmission manner of batch control information of uplink and downlink, the embodiment of the present application maps the uplink and downlink control information in the form of one control information frame, effectively improves the scheduling efficiency of the wireless communication system, and improves the real-time performance of information transmission.

[0121] In an embodiment, based on any one of the packet assembly manners in the above step S11, step S12 to step S13, or step S14 to step S15, the control information transmission method applied to the management station can support one or more terminal stations to schedule different downlink time slots and uplink time slots of different wireless frames at one time. The control information frame includes control information corresponding to the uplink time slots and the downlink time slots in different wireless frames, and the time domain allocation indication information includes time slot numbers (for example, time slot #1, time slot #2) and wireless frame offsets (for example, wireless frame offset #1, wireless frame offset #2) corresponding to the uplink time slots and the downlink time slots respectively.

[0122] The technical solution of the embodiment of the present application can also be applied in a scenario where uplink data is associated with downlink data, and the MS can determine that the terminal has uplink data to be sent after a period of time after the terminal is sent a message, for example, wireless link configuration information sent by the MS to the terminal and a response message reported by the terminal after receiving the configuration message; for example, an industrial control command and a response returned by a driver. The embodiment of the present application supports one or more terminal stations to schedule different downlink time slots and uplink time slots of different wireless frames at one time, so as to reduce the number of interactions of scheduling information and improve the scheduling efficiency of the management station. Specifically, referring to FIG. 11, when the number of terminal stations of the control information frame is 1, the uplink and downlink data scheduling information is transmitted in one control information frame, the same information in the uplink and downlink data scheduling information is represented by one field, for example, terminal station identifier B; for the fields that are contained but have different information, two fields are used to represent them respectively, for example, wireless frame offset and time slot number in part C; the terminal station identifies the type of the control information of this type (that is, the control information type of the embodiment) through the A part control information format.

[0123] The embodiment of the present application can also divide the uplink and downlink scheduling information of different wireless frames into two control information for transmission, and the same content is not merged, that is, the uplink and downlink scheduling information is regarded as control information A0-E0 and A1-E1 of different terminal stations, and only the same terminal station identifier B0 is used, and the packet assembly manner of the control information frame is as shown in FIG. 12, and there are three different control information frame generation manners, which correspond to step S11, step S12 to step S13, or step S14 to step S15 respectively.

[0124] The embodiment of the present application maps the uplink and downlink control information of different wireless frames through one control information frame, which effectively improves the scheduling efficiency of the wireless communication system and improves the real-time performance of information transmission.

[0125] In an embodiment, on the basis of any one of the packet assembling manners in the above step S11, step S12 to step S13, or step S14 to step S15, the control information transmission method applied to the management station can support the terminal station to schedule multiple downlink and / or uplink time slots in one radio frame at one time, wherein the technical solution of the embodiment of the present application can be applied in a scenario in which the data of the downlink and / or uplink time slots needs to be repeatedly transmitted to improve the reliability of the data, and one terminal can schedule multiple downlink and / or uplink time slots in one radio frame at one time.

[0126] For example, in order to improve the reliability of data transmission when the channel time domain is unstable, with reference to FIG. 13, when the number of terminal stations of the control information frame is 1, the scheduling information of the uplink / downlink time domain repeated data transmission is supported to be transmitted in one control information frame, the same information is represented by one field, for example, terminal station identifier B, time domain resource C; the fields are all contained, but the information of the fields is different, and two fields are used to represent, for example, the time slot number (for example, time slot #1, time slot #2, etc.) in the C part; the terminal station identifies the type of the control information (that is, the control information type of the embodiment) through the A part control information format.

[0127] In another embodiment, when the channel frequency domain needs to be repeatedly transmitted, as shown in FIG. 14, the scheduling information of the uplink / downlink frequency domain repeated data transmission is supported to be transmitted in one control information frame, the same information in the uplink / downlink frequency domain repeated data transmission is represented by one field, for example, terminal station identifier B, frequency domain resource D; the fields are all contained, but the information of the fields is different, and two fields are used to represent, for example, the frequency domain resource number (for example, frequency domain #1, frequency domain #2, etc.) in the D part; the terminal station identifies the type of the control information through the A part control information format.

[0128] The embodiment of the present application maps the control information of multiple uplink and / or downlink time slots of the same radio frame through one control information frame, effectively improves the scheduling efficiency of the wireless communication system, and improves the real-time performance of the information transmission.

[0129] In an embodiment, on the basis of any one of the packet assembling manners in the above step S11, step S12 to step S13, or step S14 to step S15, the control information transmission method applied to the management station can support the terminal station to schedule multiple downlink and / or uplink time slots in different radio frames at one time, wherein the technical solution of the embodiment of the present application can be applied in a scenario in which the data needs to be repeatedly transmitted in a time domain within a certain time interval to improve the reliability of the data, and one or more terminals are supported to transmit the uplink / downlink data scheduling information in one control information frame.

[0130] For example, referring to Fig. 15, when the number of terminal stations of the control information frame is 1, the same information in each downlink and / or uplink time slot is represented by one field, such as terminal station identification; the fields containing different information are represented by multiple fields, such as radio frame offset (e.g., radio frame offset #1, radio frame offset #2, etc.) and time slot number (e.g., time slot #1, time slot #2, etc.) in the C section; and the terminal station identifies the type of control information through the A section control information format.

[0131] The embodiment of the present application maps the control information of multiple uplink and / or downlink time slots corresponding to different radio frames in the form of one control information frame, effectively improves the scheduling efficiency of the wireless communication system, saves control information resources, and improves the real-time performance of information transmission.

[0132] In addition, in order to overcome the technical defects in the prior art, the embodiment of the present application also provides a control information transmission method applied to a terminal station. Referring to Fig. 16, Fig. 16 is a flowchart of an embodiment of a control information transmission method applied to a terminal station. In the second embodiment, the control information transmission method comprises the following steps:

[0133] Step A10, after receiving the wireless signal transmitted by the management station, determining the control information frame corresponding to the wireless signal;

[0134] It should be noted that the terminal station in the embodiment of the present application is located within the wireless signal coverage range of the management station. After the management station transmits the wireless signal, the terminal station can receive the wireless signal and perform the steps of conventional demodulation, decoding, and CRC check, etc., so as to obtain the corresponding control information frame.

[0135] Step A20, comparing each terminal station identification in the control information frame with a preset terminal station identification to determine matching control information;

[0136] Further, after the TS receives, demodulates, decodes, and CRC checks successfully, the terminal station identification corresponding to the B section of the control information frame carrying the control information is compared with the preset terminal station identification stored in the system buffer of the terminal station. If they are consistent, it can be determined that the control information corresponding to the terminal station identification is the control information required to be received by the terminal station. Then, the control information (C, D, E, etc.) corresponding to the preset terminal station identification can be determined according to the position of the terminal station identification in the control information frame and the length of the control information included in the control information type A. If the compared terminal station identification is inconsistent with the preset terminal station identification, the control information corresponding to the terminal station identification is discarded. In particular, if no consistent terminal station identification can be matched in the control information frame after the comparison of each terminal station identification, the control information in the control information frame is discarded.

[0137] Step A30, mapping the matching control information to corresponding communication resources to transmit data to the management station.

[0138] In which, the data to be transmitted by the terminal station indicated by the control information can be transmitted to the management station through the wireless resources indicated by the allocated time domain and frequency domain according to the information of the coding rate, modulation order and the like included in the currently determined matching control information.

[0139] The technical scheme of the embodiment of the present application can receive the control information frame containing the identification of multiple terminal stations by the terminal station, and can process the control information of multiple terminals or multiple time slots at a time, which effectively reduces the time delay, improves the scheduling efficiency of the control information, and improves the real-time performance of the information transmission compared with the batch transmission mode in the traditional control information transmission scheme.

[0140] Further, in an embodiment, the step of mapping the matching control information to corresponding communication resources comprises:

[0141] Step A31, obtaining the communication configuration information, time domain allocation indication information and frequency domain allocation indication information in the matching control information;

[0142] Step A32, mapping the matching control information to the communication resources corresponding to the time domain allocation indication information and the frequency domain allocation indication information based on the coding rate and the modulation order in the communication configuration information.

[0143] The control information frame includes A, B, C, D, E and the like, in which, E corresponds to the communication configuration information, which includes one or more of the modulation level, the coding rate, the number of antenna streams, the precoding matrix, the transmission mode mechanism indication, the power control field, the channel state information reporting indication and the like, while the time domain allocation indication information corresponds to C, which is used to indicate the time domain resources allocated to the matching control information, and the frequency domain allocation indication information corresponds to D, which is used to allocate the frequency domain resources to the matching control information, after obtaining the above parameters, the matching control information can be mapped to the wireless resources indicated by C and D.

[0144] In an embodiment, the control information frame includes a first control information frame;

[0145] The step of comparing the identification of each terminal station in the control information frame with the preset terminal station identification to determine the matching control information comprises:

[0146] Step A21, sequentially comparing the identification of each terminal station in the first control information frame with the preset terminal station identification to obtain the matching terminal station identification;

[0147] Step A22, according to the control information type of each control information, determine the corresponding matching control information of the matching terminal station identifier in the first control information frame, wherein the control information type is used to represent the length of control information.

[0148] The embodiment of the present application provides a method for comparing terminal station identifiers in the case of only one control information frame. Specifically, referring to FIG. 4, the control information of a plurality of terminal stations is carried in the first control information frame, and the A, B, C, D, E parts of the same control information are distributed in a centralized manner. The terminal station can compare the preset terminal station identifier stored in the terminal station with the terminal station identifiers B0, B1 and the like in turn, determine the terminal station identifier consistent with the preset terminal station identifier as the matching terminal station identifier, and then calculate the matching control information corresponding to the matching terminal station identifier according to the control information length in the A part corresponding to the matching terminal station identifier.

[0149] Exemplarily, if the matching terminal station identifier is B0 and the corresponding position number is 1, the corresponding control information type is A0, the first bit in the first control information frame is taken as the starting point in the calculation of the matching control information, and the matching control information (i.e., the first control information) is screened out from the first control information frame according to the control information length corresponding to A0. In addition, if the matching terminal station identifier is B3 and the corresponding position number is 4, the corresponding control information type is A3, the position corresponding to B3 is taken as the starting point, and the matching control information (i.e., the fourth control information) is screened out from the first control information frame according to the control information length corresponding to A3.

[0150] In another embodiment, the control information frame includes a second control information frame and a third control information frame, the second control information frame includes the terminal station identifiers of each control information, and the third control information frame includes at least the control information types of each control information.

[0151] The step of comparing the terminal station identifiers in the control information frame with the preset terminal station identifier and determining the matching control information includes:

[0152] Step A23, compare the terminal station identifiers in the second control information frame with the preset terminal station identifier in turn to obtain the matching terminal station identifier corresponding to the preset terminal station identifier.

[0153] Step A24, according to the position of the matching terminal station identifier in the second control information frame and the control information types of each control information in the third control information frame, determine the corresponding matching control information of the matching terminal station identifier in the third control information frame, wherein the control information type is used to represent the length of control information.

[0154] The embodiment of the present application provides a method for terminal station identification comparison in the case of two control information frames. Specifically, referring to Figure 5, the B (terminal station identification) part of the control information of the plurality of terminal stations is carried in the second control information frame, and the A, C, D and E parts of each control information is carried in the third control information frame. The terminal station can compare the preset terminal station identification stored by the terminal station with the terminal station identifications B0, B1 and the like in the second control information frame in sequence, determine the terminal station identification consistent with the preset terminal station identification as the matching terminal station identification, and then calculate the matching control information corresponding to the matching terminal station identification according to the control information length in the A part corresponding to the matching terminal station identification in the third control information frame.

[0155] For example, if the matching terminal station identification in the second control information frame is B0, and the corresponding position number is 1, then the control information type corresponding to the position in the third control information frame is A0, the first bit of the third control information frame is taken as the starting point in the calculation of the matching control information, and the matching control information (i.e. the first control information) is filtered out from the third control information frame according to the control information length corresponding to A0. In addition, if the matching terminal station identification in the second control information frame is B3, and the corresponding position number is 4, then the control information type corresponding to the position in the third control information frame is A3, the control information length sum of A0-A2 before A3 in the third control information frame is calculated first in the calculation of the matching control information, the starting point corresponding to the matching control information of B3 is obtained by adding the control information length sum to the first bit of the third control information frame, and the matching control information (i.e. the fourth control information) is filtered out from the third control information frame according to the control information length corresponding to A3.

[0156] Different from the method for terminal station identification comparison of the first control information frame in the foregoing embodiment, the terminal station identification in the embodiment of the present application is separately generated into a separate second control information frame, so that the terminal station can first analyze and compare the wireless signal corresponding to the received second control information frame, and then obtain the corresponding control information in the third control information frame after the terminal station identification consistent with the terminal station identification of the terminal station is matched. If the consistent terminal station identification cannot be matched, the process of demodulation, decoding and CRC check of the wireless signal corresponding to the third control information frame can not be performed, thereby saving the calculation resource and the communication resource to a certain extent.

[0157] In another embodiment, the control information frame comprises a fourth control information frame and a fifth control information frame, and the fourth control information frame comprises the control information type and the terminal station identification of each control information.

[0158] The step of comparing the terminal station identification in the control information frame with the preset terminal station identification and determining the matching control information comprises:

[0159] Step A25, comparing each terminal station identifier in the fourth control information frame with a preset terminal station identifier in sequence to obtain a matching terminal station identifier corresponding to the preset terminal station identifier;

[0160] Step A26, determining matching control information corresponding to the matching terminal station identifier in the fifth control information frame according to a control information type of each control information, wherein the control information type is used to represent the length of control information.

[0161] Embodiments of the present application provide a method for terminal station identifier comparison in the case of two control information frames. Specifically, referring to FIG. 6, A (control information type) and B (terminal station identifier) parts of control information of a plurality of terminal stations are carried in a fourth control information frame, and C, D, E, etc. parts of each control information are carried in the fourth control information frame. A terminal station can compare a preset terminal station identifier stored by itself with B0, B1, etc. terminal station identifiers in the fourth control information frame in sequence, determine a terminal station identifier identical to the preset terminal station identifier as a matching terminal station identifier, and then calculate and obtain matching control information corresponding to the matching terminal station identifier in a fifth control information frame according to the length of control information in the A part corresponding to the matching terminal station identifier in the fourth control information frame.

[0162] Exemplarily, if the matching terminal station identifier in the fourth control information frame is B0, and the corresponding position number is 1, then the corresponding control information type is A0, and the first bit of the fifth control information frame is taken as a starting point in calculating the matching control information, and the matching control information (i.e. the first control information) is selected from the fifth control information frame in combination with the length of control information corresponding to A0. In addition, if the matching terminal station identifier in the fourth control information frame is B3, and the corresponding position number is 4, then the control information type corresponding to this position is A3, and the length of control information of A0-A2 before A3 in the fifth control information frame is calculated according to the control type of each control information in calculating the matching control information, and the starting point corresponding to the matching control information of B3 is obtained by adding the length of control information to the first bit of the fifth control information frame, and then the matching control information (i.e. the fourth control information) is selected from the fifth control information frame in combination with the length of control information corresponding to A3.

[0163] Different from the method of terminal station identification comparison to the first control information frame in the foregoing embodiment, the terminal station identification and the control information type are separately generated into a separate fourth control information frame in the embodiment of the application, so that the terminal station can first parse and compare the received wireless signal corresponding to the fourth control information frame, determine the corresponding control information length after matching the terminal station identification matching with the terminal station identification of itself, and finally calculate and obtain the corresponding other control information in the fifth control information frame. If the consistent terminal station identification cannot be matched, the process of demodulation, decoding and CRC check of the wireless signal corresponding to the fifth control information frame can not be performed, thereby saving the calculation resource and the communication resource to a certain extent.
