[0072] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0073] The random access procedure refers to the procedure from the start of sending a random access preamble by a user to the establishment of a basic signaling connection with a network before the network is accessed. The random access procedure can include, as an example, a contention-based random access procedure (i.e., a four-step random access channel (RACH)) or a non-contention-based random access procedure (i.e., a two-step RACH), which are implemented as follows:

[0074] First, the contention-based random access procedure (i.e., the four-step RACH) can include:

[0075] (1) The terminal sends a message one, i.e., a random access preamble, to the base station.

[0076] Specifically, the terminal sends a preamble on the RACH, the main role of the preamble is to tell the base station that there is a random access request, and to let the base station estimate the time advance (TA).

[0077] There are 64 preambles in each cell, and the preambles used for competing for random access can be divided into two groups. The base station informs all terminals through the system information block (SIB) 2 about information such as which time-frequency resources are allowed to transmit preambles, two preamble groups of the terminal, a size threshold of message 3, power configuration, etc. The terminal selects a suitable preamble (or preamble ID) according to the possible size of message 3 and path loss, etc., and sends it out in a suitable random access opportunity (RACH Occasion, RO). When sending, the random access-radio network temporary identifier (RA-RNTI) is calculated according to the RO.

[0078] The terminal selects one of the two preamble groups, which actually carries 1-bit information, indicating the size of message 3 to the base station, or other transmission format information.

[0079] The communication between the base station and the terminal enables the preamble identifier (ID) and the RA-RNTI as the identity information of the terminal.

[0080] (2) The base station sends message 2, i.e. the random access response (RAR), to the terminal.

[0081] Specifically, after the terminal sends the preamble, it will listen to the physical downlink control channel (PDCCH) and the physical downlink shared channel (PDSCH) within the RAR time window. The PDCCH and the PDSCH contain RA-RNTI information, and the information carried by the RAR includes preamble ID, TA, temporary cell-radio network temporary identifier (TC-RNTI) used by message 3, and resources, etc. If no RAR from the base station is received within the RAR time window, the terminal considers that this random access process has failed, and will retransmit message 1.

[0082] The communication between the base station and the terminal uses the preamble ID and the RA-RNTI as the identity information of the terminal, while enabling the temporary cell-radio network temporary identifier (TC-RNTI) as the identity information of the terminal.

[0083] (3) The terminal sends message three, i.e., scheduled transmission, to the base station.

[0084] Specifically, the terminal sends message three on the scheduled resource using the TC-RNTI, and message three is mainly high-layer configuration information, including the international mobile subscriber identity (IMSI) of the terminal, a radio resource control (RRC) connection request, tracking information update, etc. Message three is transmitted on a physical uplink shared channel (PUSCH) and uses hybrid automatic repeat request (HARQ). When the terminal message three conflicts and the base station cannot send message four, the terminal restarts random access after reaching the maximum HARQ retransmission number.

[0085] The communication between the base station and the terminal uses the TC-RNTI as the identity information of the terminal, while obtaining the international mobile subscriber identity (IMSI) of the terminal as the unique identity information of the terminal.

[0086] (4) The base station sends message four, i.e., contention resolution, to the terminal.

[0087] Specifically, the terminal starts a timer after sending message three, and always uses the TC-RNTI to monitor the PDCCH and the PDSCH before the timer expires. The PDSCH contains the terminal message three, and the terminal finds that the message three is consistent with the locally cached message three after correctly decoding the PDSCH, and then sends ACK information and upgrades the TC-RNTI to the C-RNTI. If the timer expires, the terminal discards the TC-RNTI and considers that the random access fails.

[0088] The communication between the base station and the terminal uses the TC-RNTI as the identity information of the terminal, confirms the IMSI of the terminal, and then upgrades the TC-RNTI to the C-RNTI as the unique identity information of the terminal.

[0089] When the above four-step process between the terminal and the base station is completed, the uplink synchronization information TA and the unique identity information C-RNTI of the terminal are obtained, and the random access is successful. Next, the C-RNTI can be used for data transmission.

[0090] Second, the non-contention-based random access process (i.e., two-step RACH) can include:

[0091] (1) The terminal sends a message A (MSG-A) to the base station, that is.

[0092] Specifically, in the sending of the message A (MSG-A), the terminal directly sends the preamble and the uplink load (i.e., the PUSCH load). The content of MSG-A includes a preamble on a physical random access channel (PRACH) and a load on a PUSCH, and the load is the message three in the above-mentioned contention-based random access process, which is mainly high-layer configuration information, including terminal IMSI, RRC connection request, tracking information update, etc.

[0093] In the sending of the message A (MSG-A), one sending occupies two time slots, corresponding to the preamble and the data respectively, and a guard interval is reserved in between to reduce the influence of the preambles of other terminals on the data of the target terminal.

[0094] (2) The base station sends a message B to the terminal, i.e., contention resolution.

[0095] Specifically, after the sending of MSG-A, the terminal waits for PDCCH and PDSCH in a time window, and the PDSCH carries RAR and TA information, and the RAR includes preamble ID, C-RNTI, etc.

[0096] The above-mentioned contention-based random access process uses preamble access, if there is no collision, the terminal identity information is determined through the interaction between the network device and the terminal, and then the data transmission is started, and the process of data transmission needs to be scheduled or pre-configured resources, which limits the number of terminals.

[0097] Similarly, the above non-contention-based random access process uses a preamble to access and sends terminal identity information at the same time, which can reduce the time of preamble occupation, theoretically improve the utilization efficiency of the preamble, but still needs interaction between the network device and the terminal to determine the terminal identity information, and then data transmission can be started. The process of data transmission also needs to be scheduled or pre-configured resources, which also limits the number of terminals.

[0098] It can be seen that the above-mentioned contention-based random access process and non-contention-based random access process both need the network device to send coordination signaling to determine the terminal identity information, and then start data transmission, which limits the number of terminals that the network device can support and also has a large delay.

[0099] Therefore, the present application provides a feedback confirmation method, device, apparatus and storage medium to improve the efficiency of data transmission, especially for a large number of terminals for small packet transmission, which can accommodate a large number of terminals for random access and support a large number of terminals for data transmission, improve transmission efficiency, and also reduce coordination signaling overhead to improve the ability of the network device to support a large number of terminals.

[0100] Among them, the large number of terminals for small packet transmission can be divided into three categories:

[0101] The first category is the scene of traditional terminals, including mobile phones and the like. In this scenario, the network device needs to accurately confirm the complete identity information of the terminal, at which time the existing four-step RACH or two-step RACH scheme can be used;

[0102] The second category is a low-power wide-area network (Low Power Wide Area, LPWA) terminal, including temperature sensors and the like. In this scenario, the network device does not need to feed back to the terminal, and the temperature sensor reports KV={geographic location, temperature} to the network device, and the network device does not feed back any information to reduce the cost of the terminal;

[0103] The third category is between the first two categories, including monitoring cameras and the like. After the network device receives the data, if an error is detected, it can schedule retransmission or not schedule retransmission according to the network resource status. At this time, in order to reduce the feedback overhead, the network device does not need to accurately confirm the complete identity information of the terminal.

[0104] Among them, the method and the device are based on the same application concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be repeated.

[0105] The technical solutions provided by the embodiments of the present application can be applied to various systems, especially 5G systems. For example, the applicable systems can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, and the like. The various systems all include terminal devices and network devices. The system can also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), and the like.

[0106] The network device related to the embodiments of the present application can be a base station, which can include multiple cells serving terminals. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names. The network device can be used to exchange received air frames and Internet Protocol (IP) packets as a router between wireless terminal devices and the rest of the access network, which can include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the properties of the air interface. For example, the network device related to the embodiments of the present application can be a network device (Base Transceiver Station, BTS) in the Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (LTE) system, or a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which are not limited in the embodiments of the present application. In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be geographically separated.

[0107] The terminal device referred to in the embodiments of the present application can be a device providing voice and / or data connectivity for a user in a device having a wireless connection function, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device can also be different, for example, in a 5G system, the terminal device can be called a user equipment (User Equipment, UE). The wireless terminal device can communicate with one or more core networks (Core Network, CN) through a radio access network (Radio Access Network, RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (also known as a "cellular" phone) and a computer with a mobile terminal device, for example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDA) and the like. The wireless terminal device can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, which is not limited in the embodiments of the present application.

[0108] Figure 1 is one of the flow diagrams of a feedback confirmation method provided by the embodiments of the present application, Figure 2 is a schematic diagram of an application scenario of a feedback confirmation method provided by the embodiments of the present application; the feedback confirmation method can be used for a network device, such as: Figure 2 a base station in FIG. 1. As shown in Figure 1 , the feedback confirmation method can include the following steps:

[0109] Step 101, determining a first event, the first event including the network device detecting that the terminal accesses successfully, determining that the data sent by the terminal to the network device is successfully received.

[0110] Specifically, the first event can be detecting access success of one terminal and detecting data transmission success between the terminal and the network device; or the first event can be detecting access success of multiple terminals and detecting data transmission success between the terminals and the network device.

[0111] For example, as shown in FIG. 1, the network device detects access success of terminal 1 and determines data transmission success between terminal 1 and the network device based on the detected access information of terminal 1. At this time, the first event can be access success of terminal 1 and data transmission success between terminal 1 and the network device. Figure 2 Figure 2 For example, as shown in FIG. 1, the network device detects access success of terminal 1 and determines data transmission success between terminal 1 and the network device based on the detected access information of terminal 1. At this time, the first event can be access success of terminal 1 and data transmission success between terminal 1 and the network device.

[0112] For example, as shown in FIG. 1, the network device detects access success of terminal 1 and determines data transmission success between terminal 1 and the network device based on the detected access information of terminal 1. At this time, the first event can be access success of terminal 1 and data transmission success between terminal 1 and the network device. Figure 2 Figure 2 For example, as shown in FIG. 1, the network device detects access success of terminal 1 and determines data transmission success between terminal 1 and the network device based on the detected access information of terminal 1. At this time, the first event can be access success of terminal 1 and data transmission success between terminal 1 and the network device.

[0113] In step 102, the network device generates confirmation information according to the first event, and the confirmation information includes identification information for indicating the first event.

[0114] Specifically, if the first event is access success of one terminal and data transmission success between the terminal and the network device, the identification information can include only identification information corresponding to the terminal; if the first event is access success of multiple terminals and data transmission success between the terminals and the network device, the identification information can include identification information corresponding to each of the terminals.

[0115] In step 103, the network device sends the confirmation information to the terminal.

[0116] As can be seen from the above embodiments, after detecting access success of a terminal and determining data transmission success between the terminal and the network device, the network device can feed back confirmation information to the terminal, so that the terminal can learn access success and data transmission success through the confirmation information, improve data transmission efficiency, and combine access and transmission together, without the need for a coordination process between the network device and the terminal, thereby reducing time delay.

[0117] Optionally, the network device detecting access success of the terminal includes: the network device detecting that the first wireless signal sent by the terminal includes a preconfigured random access preamble.

[0118] ​​Specifically, the terminal sends a first wireless signal to the network device, and the first wireless signal includes a pre-configured random access preamble. When the network device detects the random access preamble, it can determine that the terminal has successfully accessed.

[0119] Optionally, the network device obtains the transmission format of the data sent by the terminal to the network device through the detected random access preamble.

[0120] Specifically, if the random access preamble indicates the transmission format of the data sent by the terminal to the network device, the data sent by the terminal to the network device can be demodulated according to the transmission format indicated by the random access preamble.

[0121] The pre-configured random access preamble can be divided into several groups, each group including at least one random access preamble, and each group of random access codes corresponds to the transmission format of the transmitted data. The transmission format includes necessary information for decoding data.

[0122] The implementation process of determining the first event is described below:

[0123] The terminal sends a first wireless signal to the network device, and the first wireless signal includes a pre-configured random access preamble and first data (i.e., data sent by the terminal to the network device), and the random access preamble indicates the transmission format information of the first data.

[0124] The network device receives the first wireless signal sent by the terminal, and the first wireless signal includes a random access preamble and first data, and the random access preamble indicates the transmission format information of the first data. In another embodiment, the random access preamble and the first data can be sent on different time-frequency resources.

[0125] The network device detects the random access preamble in the first wireless signal to obtain a detection result.

[0126] The network device obtains the transmission format information of the first data based on the detection result; if there is only one group of pre-configured random access preambles, it is considered that the first data is demodulated according to the default transmission format.

[0127] The network device detects the first data in the first wireless signal based on the transmission format information of the first data, and if the first data is successfully checked, it is determined that the first event has occurred. Specifically, the CRC check can be performed according to the CRC check bit part and the service data part in the first data, and if the check is successful, it is determined that the first event has occurred.

[0128] Specifically, the first data can be service data.

[0129] After the terminal determines the random access preamble and completes the encoding and modulation resource mapping of the service data bits, the terminal can send the random access preamble and the service data on the resource configured by the network, respectively. That is, the preamble and the data are transmitted simultaneously, and the terminal does not need to wait for the access to be successful before transmitting the data. After the network device successfully detects the data, the network device sends the confirmation information to the terminal.

[0130] The above access process can be referred to as a fusion access process, and the fusion access process has an explicit access signal (i.e., a random access preamble).

[0131] The access information of the terminal can include high-layer configuration information, including terminal IMSI, RRC connection request, tracking information update, and the like.

[0132] As can be seen from the above embodiment, the terminal does not need to wait for the access to be successful before transmitting the data, but transmits the random access preamble and the service data simultaneously, which helps to improve the efficiency of the network device feedback confirmation.

[0133] Optionally, the identification information for indicating the first event in the step 102 can include a cyclic redundancy check (CRC) bit for determining the success of data transmission between the terminal and the network device.

[0134] Specifically, the network device can use the CRC bit of the terminal data to confirm the success of the access and the data transmission to the terminal. The terminal data here can be the first data or the second data in the fusion access process.

[0135] It is worth noting that the process of CRC check processing of the data by the sending end, the length of the CRC bit, and how the receiving end obtains the CRC. The fundamental idea of CRC is to append X bits (which is the check code used for checking) to the data to be sent, generate a data packet, and send it to the receiving end. The X bits appended are not random, but make the generated data packet divisible by (modulo 2 division) a certain specific number (eigenpolynomial) selected by the sending end and the receiving end. After arriving at the receiving end, the received data packet is divided by (modulo 2 division) the selected divisor (eigenpolynomial). The result should be no remainder. If there is a remainder, it indicates that an error has occurred in the transmission process of the frame. The length of the CRC bit is usually 16 bits, but it can also be any bit, which is determined by the eigenpolynomial.

[0136] As can be seen from the above embodiments, the network device can indicate the success of the terminal's access and data transmission through the CRC used to determine the success of data transmission between the terminal and the network device. In this way, the access and transmission are combined together, and there is no need for the coordination process of the network device between the access and transmission, thereby reducing the delay.

[0137] Optionally, the identification information used to indicate the first event in the above step 102 may also include one or more of the following: random access preamble code identifier; RA-RNTI; IMSI; temporary identifier of the mobile user (Temporary Mobile Subscriber Identity, TMSI); Internet Protocol (IP) address.

[0138] Specifically, the representation method for indicating the identification information of the first event in step 102 (all representation methods are listed here, the most important method is A4, and its variants are A5 and A6. At the same time, this application does not exclude methods A1, A2, and A3) can specifically include the following six methods:

[0139] (A1) The unique terminal identity identifier, such as IMSI, TMSI, or IP address, may be 64 bits or more, which can fully guarantee the uniqueness of the terminal identity but has a large payload;

[0140] (A2) RA-RNTI, which may be 16 bits, has a small payload but can only partially guarantee the uniqueness of the terminal identity;

[0141] (A3) preamble ID, which may be 6 bits or more, has a small payload but can largely guarantee the uniqueness of the terminal identity;

[0142] (A4) Data CRC, which may be 16 bits, has a small payload but can largely guarantee the uniqueness of the terminal identity;

[0143] (A5) RA-RNTI + data CRC, which may be 16 bits, 32 bits or more, has a small payload but can basically guarantee the uniqueness of the terminal identity;

[0144] (A6) Preamble ID + data CRC, which may be 16 bits, 32 bits or more, has a small payload but can basically guarantee the uniqueness of the terminal identity.

[0145] The above-mentioned modes are optional. It should be noted that the network obtains the terminal identity information in the following modes: the RA-RNTI is calculated after the network detects the sending time position of the terminal signal; the preamble ID is directly obtained by the network after signal correlation detection; the data CRC is directly obtained by the network after decoding the terminal data; and the IMSI or TMSI or IP address or other terminal unique identity is directly read from the data part by the network after CRC check success.

[0146] As can be seen from the above embodiments, the identification information for indicating the first event can include not only the CRC bit but also the identification information for representing the terminal identity, and the representation of the identification information for representing the terminal identity can be various, so that the accuracy of the indication of the confirmation information is improved, and the diversity of the indication of the confirmation information is enriched.

[0147] Optionally, the sending of the confirmation information to the terminal comprises:

[0148] determining a sending channel for sending the confirmation information;

[0149] sending the confirmation information to the terminal through the sending channel.

[0150] As can be seen from the above embodiments, when sending the confirmation information, the sending channel can be determined, and the sending is performed through the determined sending channel, so that the accuracy of the feedback confirmation is improved.

[0151] Optionally, the sending of the confirmation information to the terminal through the sending channel comprises:

[0152] scrambling the confirmation information through a random access radio network temporary identifier (RA-RNTI) to obtain scrambled confirmation information, the RA-RNTI being determined by a sending resource position of the first wireless signal sent by the terminal;

[0153] sending the scrambled confirmation information to the terminal through the sending channel.

[0154] Specifically, after the network device receives the wireless signal sent by the terminal, the RA-RNTI can be determined according to the sending resource position of the wireless signal, so that when sending the confirmation information, the confirmation information can be scrambled by using the RA-RNTI first, and then the scrambled confirmation information is sent on the sending channel.

[0155] As can be seen from the above embodiments, when sending the confirmation information, the scrambled confirmation information can be sent through the sending channel, so that the security of the feedback confirmation is improved.

[0156] Optionally, the sending channel comprises one or more of the following: a unicast control channel; a unicast data channel; a multicast control channel; a multicast data channel.

[0157] In particular, the channel for sending the confirmation information can comprise:

[0158] (B1) a unicast control channel, a PDCCH scrambled with the confirmation information;

[0159] (B2) a unicast data channel, a PDCCH scrambled with a RA-RNTI and a PDSCH carrying the confirmation information;

[0160] (B3) a multicast control channel, similar to a physical hybrid automatic repeat request Indicator channel (PHICH), multiple confirmation information multiplexed in the control channel;

[0161] (B4) a multicast data channel, a PDCCH scrambled with a RA-RNTI and a PDSCH carrying multiple terminal confirmation information.

[0162] The above-mentioned channels can be optional.

[0163] It should be noted that any one of the above (A1) to (A6) and any one of (B1) to (B4) can be combined to form a feedback confirmation method, and embodiments of these methods can refer to the implementation process of the following embodiment one and embodiment two.

[0164] As can be seen from the above embodiments, when sending the confirmation information, the sending channel can be various, which can improve the flexibility of the feedback confirmation.

[0165] Optionally, the sending channel is a unicast data channel or a multicast data channel, and the confirmation information is located in a medium access control-control element (MAC-CE).

[0166] In particular, the MAC-CE is used for efficient communication between the terminal device and the base station at the MAC layer.

[0167] As can be seen from the above embodiments, when the sending channel is a unicast data channel or a multicast data channel, the confirmation information can be added to the MAC-CE, which improves the efficiency of the feedback confirmation.

[0168] Figure 3 Figure two is a flow diagram of a feedback confirmation method provided by an embodiment of the present application, which can be used for a terminal device, such as: Figure 2Terminal 1, terminal 2, …, terminal n in the figure.

[0169] As shown in the figure, the feedback confirmation method can include the following steps: Figure 3

[0170] Step 301, receiving the confirmation information sent by the network device, the confirmation information including the first identification information indicating the first event, the first event including the network device detecting the terminal access success and determining the successful reception of the data sent by the terminal to the network device.

[0171] Specifically, the first event can be detecting the access success and data transmission success of one terminal; it can also be detecting the access success and data transmission success of multiple terminals. Wherein, detecting the access success and data transmission success of multiple terminals is also carried out one by one, and the feedback information can be transmitted on one channel, but it is still independent.

[0172] For example: as shown in the figure, the network device detects the access success of terminal 1 and determines the data transmission success between terminal 1 and the base station based on the detected access information of terminal 1, at this time, the first event can be the access success and data transmission success of terminal 1 in the figure. Figure 2 Figure 2

[0173] For another example: as shown in the figure, the network device detects the access success of terminal 1 and determines the data transmission success between terminal 1 and the base station based on the detected access information of terminal 1; the network device detects the access success of terminal 2 and determines the data transmission success between terminal 2 and the base station based on the detected access information of terminal 2; in this way, the network device detects the access success of terminal n and determines the data transmission success between terminal n and the base station based on the detected access information of terminal n; at this time, the first event can be the access success and data transmission success of terminal 1, terminal 2, …, terminal n in the figure. Figure 2 Figure 2

[0174] Step 302, if the first identification information is the same as the second identification information, and the second identification information is the identification information used by the terminal to send data to the network device, it is determined that the terminal accesses successfully and the data transmission between the terminal and the network device is successful.

[0175] Specifically, if the first identification information is the same as the second identification information, it can be determined that the terminal accesses successfully and the data transmission between the terminal and the network device is successful; if the first identification information is different from the second identification information, retransmission can be initiated to the network device.

[0176] ​​​​​From the above embodiments, it can be seen that whether the terminal is successfully accessed and whether the data transmission between the terminal and the network device is successful can be determined by receiving the confirmation information sent by the network device, thereby improving the data transmission efficiency, and combining the access and the transmission together, without the coordination process between the access and the transmission, and reducing the time delay.

[0177] Optionally, the feedback confirmation method further comprises:

[0178] performing a cyclic redundancy check (CRC) on the first identification information and the data sent by the terminal to the network device to obtain a check result;

[0179] if the check result is a check success, determining that the first identification information is the same as the second identification information.

[0180] From the above embodiments, it can be seen that whether the first identification information is the same as the second identification information can be determined by performing a CRC check on the first identification information and the original data sent by the terminal to the network device, thereby improving the accuracy of determining whether the first identification information is the same as the second identification information.

[0181] Optionally, the feedback confirmation method further comprises:

[0182] sending a first wireless signal to the network device, the first wireless signal comprising a pre-configured random access preamble and data sent by the terminal to the network device, the random access preamble indicating transmission format information of the data sent by the terminal to the network device.

[0183] Specifically, the pre-configured random access preamble can be divided into a plurality of groups, each group comprising at least one random access preamble, and each group of random access codes corresponding to the transmission format of the transmitted data. The transmission format comprises necessary information for decoding the data.

[0184] The data sent by the terminal to the network device can be service data. After determining the random access preamble and completing the encoding and modulation resource mapping of the service data bits, the terminal can send the random access preamble and the service data on the resources configured by the network, that is, the preamble and the data are transmitted simultaneously, and the terminal does not need to wait for the access to be successful before transmitting the data. After the network device successfully detects the data, the network device sends confirmation information to the terminal.

[0185] The above access process can be referred to as a fusion access process, and the fusion access process has an explicit access signal (i.e., a random access preamble).

[0186] From the above embodiments, the terminal does not need to wait for access success to transmit data again, but transmits the random access preamble and the service data at the same time, which helps to improve the efficiency of the network device feedback confirmation.

[0187] Optionally, the first identification information includes a cyclic redundancy check (CRC) bit used to determine the success of data transmission between the terminal and the network device.

[0188] Specifically, the terminal can compare the CRC bit carried in the confirmation information with the CRC bit used when the terminal transmits data to the network device previously, if the two are the same, the first identification information and the second identification information are the same; if the two are different, the first identification information and the second identification information are different.

[0189] From the above embodiments, the success of the terminal access and data transmission can be determined through the CRC bit carried in the confirmation information, which combines the access and transmission together, and there is no need for the network device to coordinate between the access and the transmission, thereby reducing the time delay.

[0190] Optionally, the first identification information can also include one or more of the following: random access preamble identification; RA-RNTI; IMSI; TMSI; IP address.

[0191] Specifically, the representation of the first identification information (here, all the representations are listed, the most important representation is A4, the transformed representations are A5 and A6, and the application does not exclude representations A1, A2, and A3):

[0192] (A1) IMSI or TMSI or IP address or other unique identity of the terminal, which can be 64 bits or more, can completely guarantee the uniqueness of the terminal identity but has a large load;

[0193] (A2) RA-RNTI, which can be 16 bits, has a small load but can only guarantee the uniqueness of the terminal identity to a small extent;

[0194] (A3) preamble ID, which can be 6 bits or more, has a small load but can guarantee the uniqueness of the terminal identity to a large extent;

[0195] (A4) data CRC, which can be 16 bits, has a small load but can guarantee the uniqueness of the terminal identity to a large extent;

[0196] (A5) RA-RNTI + data CRC, which can be 16 bits, 32 bits or more, has a small load but can basically guarantee the uniqueness of the terminal identity;

[0197] (A6) preamble ID + data CRC, possibly 16 bits, 32 bits or more, less load but can guarantee the uniqueness of the terminal identity basically.

[0198] It should be noted that the network obtains the terminal identity information in the following ways: the RA-RNTI is calculated after the network detects the sending time position of the terminal signal; the preamble ID is directly obtained by the network through signal correlation detection; the data CRC is directly obtained by the network after detecting and decoding the terminal data; and the IMSI or TMSI or IP address or other terminal unique identity is directly read from the data part by the network after CRC check.

[0199] As can be seen from the above embodiments, the first identification information for indicating the first event can include not only the CRC bit but also the identification information for representing the terminal identity, and the representation of the identification information for representing the terminal identity can be various, which not only improves the accuracy of the indication of the confirmation information but also enriches the diversity of the indication of the confirmation information.

[0200] Optionally, the receiving the confirmation information sent by the network device comprises:

[0201] determining a receiving channel for receiving the confirmation information;

[0202] receiving the confirmation information through the receiving channel.

[0203] As can be seen from the above embodiments, when receiving the confirmation information, the receiving channel can be determined, and the confirmation information can be received through the determined receiving channel, thereby improving the accuracy of the feedback confirmation.

[0204] Optionally, the receiving the confirmation information through the receiving channel comprises:

[0205] receiving the confirmation information scrambled by the RA-RNTI, the RA-RNTI being determined by the sending resource position of the first wireless signal sent by the terminal;

[0206] descrambling the scrambled confirmation information by using the RA-RNTI to obtain descrambled confirmation information.

[0207] Specifically, when receiving the confirmation information, the terminal can obtain the RA-RNTI according to the sending resource position of the wireless signal sent by the terminal, and descramble the scrambled confirmation information by using the RA-RNTI.

[0208] As can be seen from the above embodiments, when receiving the confirmation information, the scrambled confirmation information can be received through the receiving channel, and the scrambled confirmation information is descrambled through the RA-RNTI to obtain the descrambled confirmation information, thereby improving the security of the feedback confirmation.

[0209] Optionally, the receiving channel comprises one or more of the following: a unicast control channel; a unicast data channel; a multicast control channel; and a multicast data channel.

[0210] Specifically, the channel for sending the confirmation information can comprise:

[0211] (B1) a unicast control channel, a PDCCH scrambled by the confirmation information;

[0212] (B2) a unicast data channel, a PDCCH scrambled by the RA-RNTI and a PDSCH carrying the confirmation information;

[0213] (B3) a multicast control channel, similar to a physical hybrid automatic repeat request indicator channel (PHICH), and multiple confirmation information are multiplexed in the control channel;

[0214] (B4) a multicast data channel, a PDCCH scrambled by the RA-RNTI and a PDSCH carrying multiple terminal confirmation information.

[0215] The above channels can be optional.

[0216] It should be noted that any one of (A1) to (A6) and any one of (B1) to (B4) can be combined to form a feedback confirmation method, and the embodiments of these methods can refer to the implementation process of the following embodiment one and embodiment two.

[0217] As can be seen from the above embodiments, when receiving the confirmation information, the receiving channel can be various, which can improve the flexibility of the feedback confirmation.

[0218] Optionally, the receiving channel is a unicast data channel or a multicast data channel, and the confirmation information is located in a MAC-CE.

[0219] Specifically, the MAC-CE is used for efficient communication between the terminal device and the base station at the MAC layer.

[0220] As can be seen from the above embodiments, when the receiving channel is a unicast data channel or a multicast data channel, the confirmation information can be obtained from the MAC-CE, which improves the efficiency of the feedback confirmation.

[0221] The implementation process of the feedback confirmation method is described below by two embodiments.

[0222] Embodiment one, implementation process of one terminal:

[0223] The size of the preamble group is 64, the length is 139, and the generation formula of the ZC sequence is directly used to generate. The terminal randomly selects a preamble. The ZC sequence is a commonly used sequence for generating a preamble in random access.

[0224] The terminal sends the preamble in the time slot T, the RA-RNTI corresponding to the time slot T is X (the length is 16 bits), the ID of the preamble used is Y, and the terminal sends data in the time slot T+t, the CRC bit of the data is Z (the length is 16 bits).

[0225] The network device uses a coherent detection algorithm to detect the ID of the preamble as Y in the time slot T, and then detects the data in the time slot T+t according to the prior agreement or network configuration information, and the CRC bit Z is used for successful verification.

[0226] The network device sends confirmation information, adopts mode A6+B1, that is, a new DCI format PDCCH (which can also be called a new control channel), which includes type information, indicating that the PDCCH is confirmation information for confirming that the terminal access is successful and the data sending is successful, the PDCCH is scrambled using RA-RNTI=X, and the main fields of the PDCCH are the feedback preamble ID field and the feedback CRC field, and the values of the two fields are Y and Z respectively.

[0227] The terminal receives and detects the PDCCH in the window of the time slot T+k or the m time slots before and after it, first uses RA-RNTI=X for descrambling, and then detects the PDCCH type information according to the new DCI format, if it is the PDCCH for confirming that the terminal access is successful and the data sending is successful, continue to detect the feedback preamble ID field and the feedback CRC field, if they are equal to Y and Z respectively, the terminal considers that the access is successful and the data sending is successful, otherwise (including no PDCCH is received) re-performs access and data sending.

[0228] Embodiment two, implementation process of multiple terminals:

[0229] The size of the preamble group is 64K, the length is 139, and the generation formula of the ZC sequence is directly used to generate. The terminal randomly selects a preamble.

[0230] Terminal 1 sends preamble in time slot T, the RA-RNTI corresponding to time slot T is X (length of 16 bits), the ID of the preamble used is Y1, the terminal sends data in time slot T+t, the CRC bits of the data are Z1 (length of 24 bits).

[0231] Terminal 2 sends preamble in time slot T, the RA-RNTI corresponding to time slot T is X (length of 16 bits), the ID of the preamble used is Y2, the terminal sends data in time slot T+t, the CRC bits of the data are Z2 (length of 24 bits).

[0232] Terminal n sends preamble in time slot T, the RA-RNTI corresponding to time slot T is X (length of 16 bits), the ID of the preamble used is Yn, the terminal sends data in time slot T+t, the CRC bits of the data are Zn (length of 24 bits).

[0233] The network device uses a coherent detection algorithm to detect the IDs of the preambles as Y1, Y2 and Yn in time slot T, then, according to prior agreement or network configuration information, the data in time slot T+t is detected, and the CRC bits Z1, Z2 and Zn are used for successful verification.

[0234] The network device sends confirmation information, using mode A6+B4, PDCCH (may also be referred to as a new control channel) and PDSCH, wherein the PDCCH uses RA-RNTI=X for scrambling, i.e. only the multiple terminals in time slot T are sent the confirmation information of terminal access success and data sending success, the PDCCH indicates the resource and format of the PDSCH, and in the PDSCH, the feedback preamble ID information and the feedback CRC information of the multiple terminals are multiplexed together, the multiplexing resource position can be realized by agreement or randomly, the feedback preamble ID information and the feedback CRC information of the same terminal can be arranged in sequence, i.e. Y1, Z1, Y2, Z2, Yn, Zn, or can be arranged by modulo-2 addition, i.e. Y1+Z1, Y2+Z2, Yn+Zn.

[0235] Terminal 1 receives and detects the PDCCH in the window of time slot T+k or m time slots before and after it, first uses RA-RNTI=X for descrambling, obtains the resource and format of the PDSCH according to the DCI information, continues to receive and detect the PDSCH, if the CRC bits of the PDSCH pass the verification, the terminal looks for Y1, Z1 or Y1+Z1 in the data bits, if it can be found, the terminal considers that the access and data sending are successful, otherwise (including no PDCCH is received) re-performs the access and data sending.

[0236] Terminal 2 and terminal n also perform similar operations of terminal 1.

[0237] As can be seen from the above embodiments, by merging access and transmission together, network coordination is not needed, coordination signaling of network equipment is saved, so that a large number of terminals can be supported; and the coordination process of the base station between access and transmission is also not needed, and the time delay is also reduced.
