Description

Information transmission method, device and storage medium based on unequal diversity

Technical Field

Background

As mobile communications evolve, new wireless communication systems (6G) have entered a research phase.

The increase in the number of connected devices is one of the important driving forces for 6G. Over time, the number of connected devices will increase exponentially in the near future. The connection device is mainly a machine type terminal device, and on a specific key technical index, the density of the connection device can reach tens of millions of terminals per square kilometer.

The initial access and data transmission of a huge number of terminals will be limited by the coordinated signaling resources of the network, and cannot accommodate that such number of connected devices adopts the common contention access technology. Access by a huge number of devices will also be limited by the data transmission resources of the network, even if each device occupies 1 PRB (physical resource block ) resources, several tens of thousands of PRBs or more are required, which is far greater than the total number of PRBs that can be provided in a cell, and thus a new multiple access technology needs to be adopted. Initial access and data transmission of a huge number of terminals requires a huge number of terminals to share resources, and thus collision between terminals will be unavoidable. How to obtain reliable transmission performance in case of collision still needs to be solved by means of unequal diversity transmission techniques.

All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The terminal device according to the embodiments of the present application may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing device connected to a wireless modem, etc. The names of the terminal devices may also be different in different systems, for example in a 5G system, the terminal devices may be referred to as User Equipment (UE). The wireless terminal device may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN), which may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network. Such as personal communication services (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, PDAs), and the like. The wireless terminal device may also be referred to as a system, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile), remote station (remote station), access point (access point), remote terminal device (remote terminal), access terminal device (access terminal), user terminal device (user terminal), user agent (user agent), user equipment (user device), and the embodiments of the present application are not limited.

The network device according to the embodiment of the present application may be a base station, where the base station may include a plurality of cells for providing services for a terminal. A base station may also be called an access point or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or other names, depending on the particular application. The network device may be operable to exchange received air frames with internet protocol (Internet Protocol, IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a network device (NodeB) in a wideband code division multiple access (Wide-band Code Division Multiple Access, WCDMA), an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved base station (Home evolved Node B, heNB), a relay node (relay node), a home base station (femto), a pico base station (pico), and the like. In some network structures, the network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

Multiple-input Multiple-output (Multi Input Multi Output, MIMO) transmissions may each be made between a network device and a terminal device using one or more antennas, and the MIMO transmissions may be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of the root antenna combinations.

As described in the background art, in the initial access and data transmission process of a huge number of terminal devices, since the resources of the initial access and data transmission need to be shared by a huge number of terminal devices, collision between the terminal devices is unavoidable, and thus the impact caused by collision needs to be reduced by adopting the unequal diversity transmission technique between the terminal devices.

The ALOHA algorithm is a random access method. The basic idea is that the user wants to send, does not monitor the channel, and does not send on a slot basis. As long as the user has data to send, although it is. Of course, this may cause collisions and frame corruption. On the shared broadcast channel, the sender (i.e. the terminal device) can perform collision detection during or after the data transmission, and when detecting the data transmitted by other users, it can know that the data frame is damaged. The same reason is that other users also work according to this flow. If the sender knows that the data frame is corrupted and detects a collision, it can wait for a random period of time before retransmitting the frame. The principle of ALOHA algorithm is shown in fig. 1: in fig. 1, 3 senders are sender 1, sender 2 and sender 3, respectively; the ALOHA protocol is very random, each sender can send data frames at any time, and the sent data frames are irregular; let T0 be a length specifying each data frame, i.e., a time period from just starting transmission to successful transmission of one frame; assuming that the data frame T0 transmitted by each sender is the same, the sender 1 in fig. 1 transmits the data frame at the first time, and the sender 2 begins to transmit the data frame without transmitting the data frame, so that both the sender 1 and the sender 2 fail to transmit the respective data frames; the sender 1 and the sender 2 start to randomly wait for a period of time and then retransmit the respective data frames; as shown in fig. 1, it is assumed that the data frame does not collide after the retransmission of the data frame by the sender 1, and the data frame is successfully transmitted, and the sender 2 collides with the data frame of the sender 3 when retransmitting the data frame for the first time, so that the sender 2 retransmits the data frame again.

It can be seen from fig. 1 that a collision occurs between data of different senders, but it is not known to the sender that a collision occurs by itself, because it is not listening at the time of sending the data. After the data frames of the sender are sent, the receiver receives an error data frame, and the receiver returns a NACK negative acknowledgement frame or directly does not return an acknowledgement frame; the sender receives a NACK returned by the receiver (or does not receive an acknowledgement frame beyond a given time), knows that the frame has collided on the channel and therefore will randomly wait for a time before retransmitting. The ALOHA protocol is therefore highly random, which results in a low transmission success rate.

The time slot ALOHA (slotted Aloha) algorithm divides time into a number of discrete time slots, each of equal to or slightly greater than one frame in length, all users access the network channel synchronously at the beginning of the time slot, and users can only transmit data at the beginning of each time slot. If a collision occurs, the user must wait until a subsequent time slot begins to retransmit the data. The method avoids the randomness of the user to send the data, namely, the method requires the user to send the data only at the beginning of a certain time slot, and compared with the method which can send the data at any time in fig. 1, the method has the requirement on the sending time of the data frame, so that the randomness of the user to send the data can be avoided. Thus, the data is successfully transmitted or completely collided, partial collision and collision in the ALOHA algorithm are avoided, the channel utilization rate is improved, and the throughput of the data can be doubled. The principle of operation of slotted ALOHA is shown in figure 2. As can be seen from fig. 2, the sender 1 can send a data frame at its frame arrival time, and the sender 2 can send a data frame at its frame arrival time. The sender 2 in fig. 2 sends the data frame 1 at the beginning of a time slot, and no other sender sends data in the corresponding time slot, i.e. no collision occurs, and the data will be sent successfully. The sender 1 sends the data frame 2 after a period of time, the page is successfully sent, the sender sends the data frame 3 after a certain frame arrives time, then the sender 2 sends the data frame 4, the data frame 3 and the data frame 4 generate conflict, and the sender 1 and the sender 2 randomly wait for a plurality of time slots and then carry out conflict retransmission. The slotted ALOHA protocol has higher throughput and higher efficiency than the ALOHA protocol.

The coded slotted ALOHA technique (CSA, coded slotted Aloha) is an implementation of a typical inter-terminal unequal diversity transmission technique. The CSA can obviously improve the throughput of the common slotted Aloha. A schematic diagram of the CSA scheme is shown in fig. 3. On the sender side, the sender firstly divides a burst to be sent into k segments, the length of each segment is the same, the k segments generate nh segments through channel coding, and the segment lengths before and after coding are the same; a MAC frame is uniformly divided into kM slices, each slice carrying a corresponding encoded segment. The terminal randomly selects nh slices, and transmits nh coded segments, wherein each segment contains the position information of other segments.

For example, the original data shown in fig. 3 includes a data segment1 and a data segment2, and 4-segment data including segment1, segment2, segment3, and segment4 is obtained after encoding. Wherein, segment1 and segment3 data content are the same, and segment2 and segment4 data content are the same. When 4 slices as shown in fig. 3 are used to transmit segments 1, 2, 3 and 4, successful data transmission can be transmitted only by two pieces of data with different contents.

Therefore, in the CSA scheme, different nh values can be taken among the senders, and the nh slice positions among the senders can not be completely the same, so that the transmission of unequal diversity can be realized.

On the network device side, k segments are decoded by using received segments without interference or with smaller interference, coded segments on other slices are obtained, and the segments of each terminal are finally obtained by using SIC technology.

The CSA mainly realizes different numbers of encoded segments and different data transmission positions between the senders, and can obtain improved performance compared with the technology of the same diversity factor of complete collision. However, CSA has not been standardized due to its high implementation complexity. As such, how to transmit information based on unequal diversity order remains to be solved.

In view of this, embodiments of the present application provide an information transmission method, apparatus, and storage medium based on unequal diversity order.

In an embodiment of the present application, an information transmission method based on unequal diversity order of a puncturing operation is provided. The punching operation refers to punching the data to be punched to be transmitted, and the data at the punching position in the data to be punched is not transmitted or is replaced by other specified data to be transmitted. Different terminal devices adopt different punching schemes, so that data transmission schemes with different punching positions and/or punching numbers can be realized, and unequal diversity is realized. In short, the implementation of unequal diversity order in the embodiments of the present application is implemented based on a puncturing operation, where the puncturing operation is used to make the puncturing positions and/or the number of punctures of data of a plurality of terminal devices sharing the same transmission resource identical.

As shown in fig. 4, a flow chart of a method for transmitting information with unequal diversity order provided in an embodiment of the present application is shown, and the method is applicable to a terminal device, and includes the following steps:

in step 401, a puncturing operation is performed on the data to be punctured, so as to obtain target data.

The transmission of the data needs to be encoded to generate multiple data for the original transmission (for example, the encoding in the CSA scheme is implemented to transmit the original data), so long as one data is completely transmitted successfully, the successful transmission of the one complete data is ensured as much as possible based on the punching operation. The embodiment of the application mainly focuses on how to realize unequal diversity order.

In the embodiment of the present application, the puncturing operation makes the puncturing positions and/or the number of punctures of the data of a plurality of terminal devices sharing the same transmission resource different, thereby implementing unequal diversity.

How the data corresponding to the punching position of the punching operation is processed during implementation can be adjusted according to actual conditions, so that the punching operation is simple and convenient to implement, and the unequal diversity order provided by the application does not need to consume excessive processing resources.

In step 402, target data is transmitted.

In summary, in the embodiment of the present application, unequal diversity of data is achieved through a punching operation. The puncturing operation ensures that at least one data is transmitted in its entirety. The core of the embodiment of the present application is to propose to implement unequal diversity order based on the punching operation, which is described in detail below.

In some possible embodiments, the data granularity of the data to be punctured is any one of a data block, bit, or symbol. Thus, in a puncturing operation, the granularity of data may be punctured based on blocks, bits, or symbols of data. Therefore, unequal diversity is achieved based on punching operation in the embodiment of the application, data granularity can be flexibly adjusted, and more efficient data transmission is achieved. For example, while intelligence in the CSA scheme may transmit data at segment granularity, embodiments of the present application may transmit data at data block, bit, or symbol granularity. The smaller the granularity, the higher the gain, the more terminal devices share the same resource to transmit data. For example, when the segment granularity is adopted, the number of terminal devices on each diversity order is higher, depending on the number of segments, the granularity of the segment is obviously higher than the bit granularity, the segment division mode is less than the bit granularity division mode, the number of terminal devices on the same diversity order is obviously higher than the number of terminal devices divided according to the bit granularity, the more the number of terminal devices on the same diversity order is, the higher the collision possibility is, the number of terminal devices on the same diversity order is reduced, and the same diversity performance is improved. Therefore, in the embodiment of the application, different granularities can be flexibly adopted based on the punching operation mode, compared with a CSA scheme, the method is more flexible, and transmission performance can be improved and promoted by adopting small granularities.

In some possible embodiments, each binary sequence in the set of binary sequences comprises a first mark and a second mark, and the number and/or positions of the first marks in different binary sequences are different, the second mark positions corresponding to the punch positions.

In some possible implementations, the puncturing operation may be implemented using a set of binary sequences, including determining a puncturing sequence for the puncturing operation based on the set of binary sequences. The binary sequence set includes a plurality of binary sequences, and the binary sequences include a first mark and a second mark. For example, a first flag is 1 and a corresponding second flag is 0. Or the first flag is 0 and the second flag is 1. In some embodiments, the data and/or positions of the first mark in the different binary sequences are different, the first mark may correspond to 0, the second mark may correspond to 1, for example, the first mark position corresponds to a position where no puncturing is required, and the second mark position corresponds to a puncturing position, thereby realizing that the data of different terminals are different in puncturing position and/or number of puncturing, and thus realizing unequal diversity. For example, the binary sequence a is 010101, and the binary sequence B is 101010, so that 1 corresponds to the puncturing positions to be punctured, and although the number of the puncturing positions in the binary sequence is the same, the positions are different, if the data is punctured according to the sequence a, the puncturing positions are data which do not need to be transmitted, and the 2 nd, 4 th and 6 th block data do not need to be transmitted based on the sequence a. If the punching operation is performed based on the sequence B, the 1 st, 3 rd and 5 th data do not need to be transmitted; the different locations of the data blocks transmitted thereby achieve unequal diversity of the data. The mode of binary sequence set can simply and conveniently realize punching operation. And the different punching positions and/or the different punching numbers of different punching operations are realized based on different binary sequences, the binary sequence has small data size, convenient operation and less occupation of resources.

In practice, the set of binary sequences may be determined based on an indication message sent by the network device; and/or determining a set of binary sequences based on the protocol conventions; the indication message may include a set of binary sequences available to the respective terminal devices, etc., or the indication message may include parameter information generating a set of binary sequences available to the respective terminal devices, etc. For example, the network device may indicate the set of binary sequences that each terminal device may employ via broadcast signaling.

When the terminal device performs the puncturing operation, the puncturing sequence may be determined based on the binary sequence set, and then the puncturing operation may be performed using the puncturing sequence. In a possible implementation, the terminal device may select one binary sequence from the set of binary sequences as the puncturing sequence. A puncturing operation is then performed based on the puncturing positions in the puncturing sequence. For example, the position marked 1 in the puncture sequence is reserved for transmission, and the data of the position marked 0 is not transmitted or is replaced with other specified data for transmission.

In implementation, as different binary sequences exist in the binary sequence set, different terminal devices can realize unequal diversity factor by performing punching operation by adopting different binary sequences as far as possible.

In another embodiment, in order to increase performance of unequal diversity, in this embodiment of the present application, the terminal device may not only select one binary sequence from the binary sequence set as the puncturing sequence, but also select a plurality of binary sequences and generate one binary sequence using the plurality of binary sequences as the puncturing sequence.

In some possible implementations, the embodiments of the present application may provide three exemplary methods for generating a puncturing sequence:

method 1), sequentially performing OR operation on each bit of the plurality of binary sequences to obtain a punching sequence.

For example, 3 binary sequences, namely binary sequence 1, binary sequence 2 and binary sequence 3, are selected, the binary sequences 1 and 3 can be bitwise or operated, for example, the 1 st bit in the binary sequence 1 and the 1 st bit in the binary sequence 2 are or operated, so as to obtain the 1 st bit of the new binary sequence 4, and the like, so as to obtain the new binary sequence 4, then the binary sequences 4 and 3 are bitwise or operated, so as to obtain the new binary sequence 5, and the binary sequence 5 is the punching sequence.

Method 2), performing AND operation on each bit of the plurality of binary sequences in sequence to obtain a punching sequence.

For example, 3 binary sequences, namely binary sequence 1, binary sequence 2 and binary sequence 3, are selected, and the binary sequences 1 and 3 can be bitwise and operated, for example, the 1 st bit in the binary sequence 1 and the 1 st bit in the binary sequence 2 are operated to obtain the 1 st bit of the new binary sequence 4, and the like, so as to obtain the new binary sequence 4, then the binary sequences 4 and 3 are operated to obtain the new binary sequence 5, and the binary sequence 5 is the punching sequence.

Method 3), performing exclusive OR operation on each bit of the plurality of binary sequences in sequence to obtain a punching sequence.

For example, 3 binary sequences, namely binary sequence 1, binary sequence 2 and binary sequence 3, are selected, the binary sequence 1 and binary sequence 3 can be subjected to exclusive or operation bit by bit, for example, the 1 st bit in the binary sequence 1 and the 1 st bit in the binary sequence 2 are subjected to exclusive or operation to obtain the 1 st bit of a new binary sequence 4, and the like, so as to obtain the new binary sequence 4, then the binary sequence 4 and the binary sequence 3 are subjected to exclusive or operation bit by bit to obtain a new binary sequence 5, and the binary sequence 5 is a punching sequence.

Thus, as long as the operation is performed at the bit granularity, different binary sequences can be generated, and the specific manner of the bit operation in the embodiments of the present application is not limited.

In another embodiment, the terminal device may be signaled which puncturing sequence to employ based on the network side. The network side signaling is, for example, broadcast signaling, which binary sequence is adopted by the terminal device as a puncturing sequence, or a puncturing sequence is generated based on a plurality of binary sequences.

In addition, the terminal device may also determine the puncturing sequence according to the data characteristics of the data to be punctured to be transmitted.

For example: in the embodiment of the present application, the manner of determining the puncturing sequence based on the data features may be implemented as follows:

determining the puncturing sequence pattern 1):

if the data granularity of the data to be punched is the data block, acquiring first appointed number of data information of a first appointed position of the data to be punched; wherein each location corresponds to data of a single data granularity; for example, the first designated location is the last data block of the data to be punctured, or the first data block, or any data block in the middle. Of course, the number of data blocks may be unlimited, and may be the last n data blocks, for example.

A binary sequence required for the data to be punctured is determined based on the data information. Taking the last data block as an example, the last m bits may be taken to determine which or which binary sequence to select. E.g., bit 01, identifying the first binary sequence to be selected, bit 10 indicating the first two binary sequences to be selected.

Determining the puncturing sequence pattern 2):

if the data granularity of the data to be punched is bit, determining a binary sequence required by the data to be punched based on the number of the designated bits contained in the data to be punched.

For example, the designated bit is 1, the data to be punctured is 10001, and since there are two 1 in the data to be punctured, two binary sequences corresponding to 1 are selected, and the binary sequences corresponding to 1 may be 1 or more, for example, when two bits 1 correspond to one binary sequence, the terminal device may use the binary sequence as a puncturing sequence, and if two bits 1 correspond to multiple binary sequences, the terminal device may use the multiple binary sequences to generate one puncturing sequence. The corresponding relation between the number of the bits 1 and the binary sequence in the specific implementation can be determined according to the actual requirement. The corresponding relation can be configured according to actual needs, so long as the punching operation can be realized, and different terminal equipment can be screened and used for different punching sequences as far as possible.

Determining the puncturing sequence pattern 3):

if the granularity of the data to be punctured is a digital modulation symbol, determining a binary sequence required by the data to be punctured based on a second designated number of digital modulation symbols at a second designated position in the digital modulation symbols.

Similarly, when determining the binary sequence based on the digital modulation symbol, the specific rule is not limited, as long as different terminal devices can use different puncturing sequences to perform puncturing operation.

After the puncturing sequence is obtained, the terminal device may perform a puncturing operation on the data to be punctured based on the puncturing position in the puncturing sequence, and may delete (i.e. not perform data transmission) or replace the data corresponding to the puncturing position with the specified data. When the data is replaced by the specified data, the data of the punching position in the data to be punched can be replaced by the specified data for transmission.

In this embodiment of the present application, in order to facilitate the network device to analyze the data to be punctured, the terminal device may send relevant control information of the puncturing operation to the network device, so that the network device obtains the data to be punctured based on the control information. For example, the related control information may include a sequence number or a puncturing sequence of a binary sequence employed by the terminal device. Therefore, the network equipment can carry out data detection on the target data based on the related control information and the binary sequence set to obtain the data to be punctured.

Based on the same inventive concept, the embodiment of the present application further provides an information transmission method implemented by a network device and based on unequal diversity order, as shown in fig. 5, including the following steps:

in step 501, a set of binary sequences for a puncturing operation is generated.

As described above, the binary sequence set is used to instruct the terminal device to perform a puncturing operation on the data to be punctured, where the puncturing operation is used to make the puncturing positions and/or the number of punctures of the data of the plurality of terminal devices sharing the same transmission resource different.

In step 502, the binary sequence set or parameter information generating the binary sequence set is transmitted to the terminal device.

Thus, the terminal device can realize the punching operation based on the binary sequence set, so that the data transmission positions or the number of different terminal devices are different as much as possible.

For example, as shown in fig. 6, a flow chart for implementing unequal diversity transmission for interaction between a terminal device and a network device includes:

in step 601, the network device signals the set of binary sequences to the terminal device.

In step 602, the terminal device generates a puncture sequence using a set of binary sequences.

In step 603, the terminal device performs a puncturing operation on the coded data to be punctured by using a puncturing sequence, obtains target data, performs data transmission, and sends relevant control information of the puncturing operation to the network device.

In step 604, the network device receives relevant control information sent by the terminal device for the data to be punctured;

in step 605, the network device determines a puncturing sequence for the puncturing operation by the terminal device based on the set of binary sequences and the associated control information.

The manner of generating the puncturing sequence may be the same as the terminal device side method, except that the network device determines the puncturing sequence employed by the terminal device based on the relevant control information of the terminal device.

For example, the related control information may be a sequence number of at least one binary sequence selected by the terminal device, and if the terminal device selects one binary sequence from the binary sequence set, the network device selects the binary sequence selected by the terminal device from the binary sequence set as a puncturing sequence;

if the terminal device selects a plurality of binary sequences from the binary sequences, the network device generates one binary sequence as a puncture sequence based on the plurality of binary sequences in the binary sequence set.

In step 606, the network device performs a detection operation on the target data based on the puncturing sequence, to obtain data to be punctured.

For ease of understanding, several embodiments are given below to illustrate the information transmission method based on unequal diversity provided in the embodiments of the present application.

Embodiment 1 is implemented for unequal diversity order of data block granularity.

Assuming that the number of data blocks is generally not more than 8, the length of 4 binary sequences transmitted using base station broadcast signaling is 8, a1= [ 00 00 00 00 ], a2= [ 01 00 10 00 ], a3= [ 10 10 00 00 ], a4= [ 00 00 10 10 ], respectively. It should be noted that the number and length of binary sequences are not limited, but are merely illustrative.

The original data to be transmitted by the terminal device is information bits. The whole processing flow is that each terminal device sequentially carries out operations such as CRC, coding, interleaving, code rate matching, scrambling, digital modulation, resource mapping, unequal diversity punching, OFDM modulation, antenna mapping and the like on information bits and then sends the information bits.

Wherein the unequal diversity punching operation is as follows. The terminal device may use the last two bits of the information bits to determine which binary sequences to select. Assuming that the last 2 bits adopted by the terminal device 1 are 00, the terminal device 1 will perform a puncturing operation on the data blocks according to a1, i.e. the terminal device 1 normally transmits 8 data blocks, with a diversity order of 8. Assuming that the last 2 bits of the information bits to be transmitted by the terminal device 2 are 01, the terminal device 2 performs a puncturing operation on the data blocks according to the binary sequence [ 01 00 10 00 ] obtained by the or operation of a1 and a2, that is, the terminal device 2 normally transmits the 1 st, 3 rd, 4 th, 6 th, 7 th and 8 th data blocks, and does not transmit the 2 nd and 5 th data blocks, and the diversity degree is 6. Assuming that the last 2 bits of the information bits to be transmitted by the terminal device 3 are 10, the terminal device 3 performs a puncturing operation on the data blocks according to the binary sequence [ 11 10 10 00 ] obtained by the or operation of a1, a2, a3, i.e., the terminal device 3 normally transmits the 4 th, 6 th, 7 th, 8 th data blocks, and does not transmit the 1 st, 2 nd, 3 th, 5 th data blocks, with a diversity order of 4. Assuming that the last 2 bits of the information bits to be transmitted by the terminal device 4 are 11, the terminal device 3 performs a puncturing operation on the data blocks according to the binary sequence [ 11 10 10 10 ] obtained by the or operation of a1, a2, a3, a4, i.e., the terminal device 3 normally transmits the 4 th, 6 th, 8 th data blocks, and does not transmit the 1 st, 2 nd, 3 rd, 5 th, 7 th data blocks, with a diversity order of 3. Thus realizing unequal diversity among the terminal devices.

Example 2: unequal diversity implementation for bit granularity

In the embodiment of the present application, n=16 binary sequences specified by the protocol standard, for example a1= [0 0 0 0 0 0 0 0 … ], a2= [0 1 0 0 1 0 0 0 … ], a3= [1 0 1 0 1 0 1 0 … ], …, an= [0 0 0 11 0 1 0 … ], where each sequence length is 1192, only the values of the first 8 bits in the binary sequence are given. The 16 sequences can be obtained through computer searching, and the positions of 1 are as different as possible, and the number of 1 is as different as possible.

In this embodiment, the original data to be sent by the terminal device is information bits, and each terminal device performs operations such as CRC, coding, interleaving, rate matching, scrambling, unequal diversity punching, digital modulation, resource mapping, OFDM modulation, antenna mapping, and the like on the information bits, and sends the information bits, where the unequal diversity punching is as follows. According to a predetermined convention, the number of elements 1 contained in the CRC bits of the information bits corresponds one-to-one to the binary sequence. Assuming that the CRC bits of the information bits to be transmitted by the terminal device 1 contain 6 1 s, the terminal device 1 corresponds to the selection sequence a1, and the terminal device 1 performs a puncturing operation on the data block according to a1, that is, the terminal device 1 normally transmits 1192 bits, and the diversity order is 1192. Assuming that 8 CRC bits of the information bits to be transmitted by the terminal device 2 contain 1, the terminal device 2 corresponds to the selection sequence a2, and then the terminal device 2 performs a puncturing operation on the data block according to a2, that is, after interleaving and rate matching of the coded bits of the terminal device 2, the 2 nd bit, the 5 th bit, …, and so on are punctured, that is, the bits 0 are transmitted at the positions of the bits. Assuming that the CRC bits of the information bits to be transmitted by the terminal device 3 contain 9 1 s, the terminal device 3 corresponds to the selection sequence a3, and then the terminal device 3 performs a puncturing operation on the data block according to a3, that is, after interleaving and rate matching of the coded bits of the terminal device 3, punctures the 1 st bit, the 3 rd bit, the 5 th bit, the 7 th bit, …, and so on, that is, transmits bit 0 at the positions of the bits. Assuming that the CRC bits of the information bits to be transmitted by the terminal device k contain 16 1 s, the terminal device k corresponds to the selection sequence an, and then the terminal device k performs a puncturing operation on the data block according to an, that is, after interleaving and rate matching of the coded bits of the terminal device k, punctures the 4 th bit, the 5 th bit, the 7 th bit, …, and so on, that is, transmits the bit 0 at the position of the bits. Thus realizing bit-level unequal diversity among terminal devices.

Example 3: unequal diversity order implementation for digital modulation symbol granularity

10 sequences transmitted by using base station broadcast signaling, including a1= [ 0000 0000 … ], a2= [ 010 010 00 … ], a3= [ 1010 1010 … ], …, a10= [ 0001 1010 … ], each of which has a length of 144, only the values of the first 8 bits in the binary sequence are given here, the 10 sequences can be obtained by searching by a computer, the positions satisfying 1 are as different as possible, and the number of 1 is as different as possible. In addition, the length of the sequence can be adjusted according to practical situations, and the length is generally greater than or equal to the length of the digital modulation symbol.

In this embodiment, the original data to be sent by the terminal device is information bits, and each terminal device performs operations such as CRC, coding, interleaving, code rate matching, scrambling, digital modulation, unequal diversity punching, resource mapping, OFDM modulation, antenna mapping, and the like on the information bits, and sends the information bits, where the unequal diversity punching is as follows. Assuming that the information bits to be transmitted by the terminal device 1 are encoded by a given encoding scheme to obtain 0000, and this encoding is only used to determine the or operation between a1-a10, then the terminal device 1 determines a1 (not performing or operating with other sequences) according to 0000, and then performs the puncturing operation on the digital modulation symbols according to a1, that is, the terminal device 1 normally transmits all the digital modulation symbols with a diversity order of 144. Assuming that the information bits to be transmitted by the terminal device 2 are encoded by a given encoding mode to obtain 0001, and the encoding is only used for determining the or operation between a1 and a10, the terminal device 2 determines the or operation between a1 and a2 according to 0001 to obtain a binary sequence [ 010 010 00 … ], and then performs the puncturing operation on the digital modulation symbols, that is, the terminal device 2 normally transmits the 1 st, 3 rd, 4 th, 6 th, 7 th and 8 th … th digital modulation symbols, and does not transmit the 2 nd and 5 th … th digital modulation symbols, and the diversity degree is less than 144. Assuming that the information bit to be transmitted by the terminal device 3 is encoded by a given encoding mode to obtain 0010, the terminal device 3 determines a1, a2, a3 or operation according to 0010 to obtain a binary sequence [1 1 1010 00 … ], and then performs a puncturing operation on the digital modulation symbol, that is, the terminal device 3 normally transmits the 4 th, 6 th, 7 th and 8 … th digital modulation symbols, and does not transmit the 1 st, 2 nd, 3 rd and 5 th … th digital modulation symbols, where diversity degree is less than 144. Assuming that the information bits to be transmitted by the terminal device 10 are encoded by a given encoding mode to obtain 1010, the terminal device 10 determines that a1, a2, a3, a4 or operation is performed according to 1010 to obtain a binary sequence [1 1 1010 10 … ], and then performs a puncturing operation on the data block, that is, the terminal device 10 normally transmits the 4 th, 6 th and 8 th … digital modulation symbols, and does not transmit the 1 st, 2 nd, 3 rd, 5 th and 7 th … digital modulation symbols, where the diversity degree is less than 144. Thus realizing unequal diversity among the terminal devices.

Example 4 data detection based on unequal diversity order

Whether it is a set of binary sequences specified by the standard or a set of binary sequences transmitted by the base station via broadcast signaling, the base station receiver can learn all binary sequence information.

By receiving and detecting the metadata signal, the base station receiver can know the information bits of the terminal device, or the CRC bits of the information bits, or the code bits of the information bits, thereby knowing the data puncturing position of the terminal device.

For example, for embodiment 1 or 3, the base station receiver knows that the terminal device at the puncturing position does not transmit any data signal, and for embodiment 2, the base station receiver knows that the bit transmitted by the terminal device at the puncturing position is 0.
