Description
Technical Field
The present application relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for generating a user characteristic pattern.
Background
The 5 th Generation mobile communication technology (5G) is a new mobile communication technology proposed to meet the rapid development of smart terminals and mobile internet, and needs to have a capability of supporting mass connection. Since the conventional orthogonal multiple access technology requires orthogonal transmission of users on physical resources such as time domain, frequency domain, code domain, etc., this limits the access number of users. Therefore, non-orthogonal multiple access techniques have emerged.
Pattern Division Multiple Access (PDMA) technology is one of the emerging non-orthogonal Multiple Access technologies. The main processing ideas of the PDMA technology are as follows: the transmitting end superposes a plurality of user signals on the same physical resource according to different schemes, and the receiving end adopts an advanced demodulation algorithm to realize the separation of the user signals, thereby realizing the purposes of improving the frequency spectrum utilization rate of the system and increasing the number of access users. Specifically, at a transmitting end, non-orthogonal superposition transmission of multi-domain signals such as a time-frequency domain, a power domain and a space domain is realized by designing a multi-user unequal diversity characteristic pattern. At the receiving end, an advanced receiver is adopted for demodulation, and the separation of different user signals is realized.
The characteristic pattern of the user is a vector formed by '0' and '1', reflects the mapping relation between the user signal and the resource block, and is used for determining the resource blocks on which the user signal is transmitted. Where "1" indicates that the user signal is transmitted on the corresponding resource block, and "0" indicates that the user signal is not transmitted on the corresponding resource block. The number of "1" in the user's characteristic pattern indicates the transmission diversity degree of the user. The characteristic patterns of all users form a PDMA pattern matrix, and the PDMA pattern matrix reflects the superposition mode of the signals of the users on each resource block. The pattern matrix of the PDMA may be represented in the form of a matrix of N rows and M columns, where "row" represents a multiplexed resource block and "column" represents a characteristic pattern of a user.
Currently, the transmitting end generates a fixed characteristic pattern for each user. The disadvantage of this approach is that, when the total characteristic pattern resource pool is limited, the total number of users that can access the network simultaneously to use the resource block is limited, and there is a case where users compete to use the resource block (user collision). For example, when the total characteristic pattern resource pool is 10 bits, the number of users capable of simultaneously using resource blocks is at most 1024, and if the number of users needing to use resource blocks is greater than 1024, a user collision occurs.

A user characteristic pattern generation method provided in an embodiment of the present application is described below with reference to fig. 1 to 4.
As shown in fig. 1, a method for generating a user characteristic pattern provided in an embodiment of the present application may include:
The Identity (ID) of the user is an identifier for uniquely identifying and distinguishing the user Identity, and it is understood that the Identity of different users is different. In practical applications, different users represent different terminal devices.
In the embodiment of the application, the identity of the user is represented by a string of binary digits.
The target user can be understood as a user who needs to generate the user characteristic pattern currently.
Assuming that the total number of users in the system is K, each user has a unique ID, and the ID of the target user K can be recorded as ID (K), where K is greater than or equal to 1 and less than or equal to K.
And 102, copying the binary digit string according to a preset mode to generate a binary digit sequence.
The preset modes may include, but are not limited to: sequential replication and/or reverse order replication. Specifically, the binary digit string representing the identity of the target user may be copied in a preset manner to generate an infinitely long binary digit sequence. For example, assume that the ID of target user k is: 10110011, continuously copying n times according to a sequential copying mode to obtain a binary digit sequence repeatedly arranged by n '10110011'; by copying n times in succession in the reverse order, a binary digit sequence consisting of n repeated sequences of "11001101" is obtained.
And 103, reading a binary digit from the generated binary digit sequence in sequence according to a preset time interval and inputting the binary digit into a shift register with a preset digit.
The preset time interval may be set manually, and may also be adjusted according to actual needs, in this embodiment of the application, the preset time interval is not required to be fixed, and in general, the preset time interval is in the order of ms, for example, 10 ms.
The preset digit can also be set manually according to actual needs. However, in order to make the shift register have good pseudo-random characteristics, and thus ensure that the characteristic patterns generated at the same time for different users are different, the preset number of bits may be N, where N is the total number of physical resource blocks that the base station can allocate to the users. Of course, the preset digit may also be greater than N, and when the preset digit is greater than N, the probability that the feature patterns generated for different users are inconsistent is greater, which is more helpful to avoid user collision.
In general terms, the amount of the solvent to be used,
where, as mentioned above, K is the total number of users of the system,
meaning rounding up.
In step 103, "in-order read" may be either a sequential read or a reverse read.
In one embodiment, when the shift register for reading the binary number is the leftmost shift register (also called left shift register), the shift registers of the predetermined number of bits are all shifted to the right by one bit when reading the binary number.
Specifically, as shown in FIG. 2, for the inclusion D1-DN A shift register 2 for left shifting N storage bits, a binary digit D of one bit to be read0When input is input from the right end of the shift register 2, all the binary numbers currently stored in the storage bits in the shift register 2 are shifted to the left by one bit, so that Dn＝Dn-1，D1＝D0Wherein N is more than or equal to 1 and less than or equal to N.
In another embodiment, when the shift register for reading the binary data is the rightmost shift register (also called right shift register), the shift registers of the predetermined number of bits are all shifted by one bit to the left when reading the binary data.
Specifically, as shown in FIG. 3, for the inclusion D1-DNA right shift register 3 of N storage bits, a one-bit binary number D to be read0When input is made from the left end of the right shift register 3, all the binary numbers currently stored in the storage bits in the right shift register 3 are shifted to the right by one bit, so that Dn＝Dn-1，D1＝D0Wherein N is more than or equal to 1 and less than or equal to N.
In this embodiment of the present application, besides the left shift register and the right shift register, the shift register with the preset number of bits may also be another shift register with good pseudo-random characteristics, which is not limited in this embodiment of the present application.
And 104, after the binary number is read, generating the characteristic pattern of the target user according to the binary number sequence stored in the shift register with the preset digit.
The method comprises the steps of reading a binary digit sequence generated in the step 102 from the binary digit sequence at preset time intervals, inputting a shift register with preset digits, and generating the characteristics of the target user according to the binary digit sequence stored in the shift register with preset digits after reading is finished each timeTherefore, the characteristic pattern corresponding to the target user k changes along with the time t, and the characteristic pattern generated for the target user k can be recorded as Pk(t), wherein t represents time, and K is greater than or equal to 1 and less than or equal to K.
Characteristic pattern P of target user kkAnd (t) is a vector consisting of '0' and '1', reflects the mapping relation between the target user k signal and the resource blocks, and is used for determining the resource blocks on which the target user k signal is transmitted. Where "1" indicates that the signal of the target user k is transmitted on the corresponding resource block, and "0" indicates that the signal of the target user k is not transmitted on the corresponding resource block.
In one embodiment, step 104 may comprise: and determining the binary digit sequence stored in the shift register with the preset digit number as the characteristic pattern of the target user. For example, the binary digit sequence stored in the N-bit shift register shown in fig. 2 or fig. 3 is determined as the characteristic pattern of the target user.
In addition, a partial sequence in the binary digit sequence stored in the shift register with the preset number of bits may be determined as the characteristic pattern of the target user.
In step 104, generally, when a binary digit is stored in each storage bit of the shift register with the preset number of bits, the feature pattern of the target user is generated based on the binary digit sequence stored in the shift register with the preset number of bits. Of course, when a partial sequence in the binary digit sequence stored in the shift register with the preset number of bits is determined as the feature pattern of the target user, it may not be required that each storage bit of the shift register with the preset number of bits stores a binary digit.
According to the user characteristic pattern generation method provided by the embodiment of the application, a one-bit binary number is read from a binary number sequence obtained by copying a binary number string representing the user identity, a shift register with preset bits is input to obtain the characteristic pattern of a target user, and the binary number strings representing different user identities are different, so that different characteristic patterns can be generated for different users, and the problem of user collision is not easy to occur.
In addition, because the binary number is read from the generated binary number sequence and the shift register with the preset number of bits is input continuously according to the preset time interval, the characteristic pattern of the target user can be ensured to change along with the change of time instead of being kept unchanged all the time, and the target user can better resist the selective fading of the channel, thereby improving the performance of the system.
Optionally, in another embodiment of the present application, after the step 103 and before the step 104, the method for generating a user characteristic pattern provided in the embodiment of the present application may further include:
and taking the logic operation result of the binary number shifted out from the first storage bit and the binary number shifted out from the second storage bit as the value of the third storage bit.
The first storage bit and the third storage bit are two adjacent storage bits in the shift register with the preset number of bits, and the second storage bit is a storage bit behind the third storage bit in the shift register with the preset number of bits.
The above logical operations may include, but are not limited to: and operation, or operation and exclusive or operation. In general, the "sum operation" may be represented by the symbol "&" and the "or operation" may be represented by the symbol "/". The xor operation may be denoted by [ ] with the symbol.
For example, as shown in fig. 4, assuming that the shift register with the preset number of bits is a shift register 4 with 19 bits (N ═ 19) to the right, the first storage bit and the third storage bit may be D2And D3The second stored bit may be D17When a one-bit binary number D is read from the binary number sequence generated in step 102 above0After being input into the shift register 4, D can be shifted to the right2Shifted out value and D17Exclusive OR operation of shifted-out values with the result D3A value; likewise, the first and third memory bits may also be D3And D4The second stored bit may be D16When a one-bit binary number D is read from the binary number sequence generated in step 102 above0After being input into the shift register 4, D can be shifted to the right3Shifted out value and D16Exclusive OR operation of shifted-out values with the result D4Value, and so on.
As shown in fig. 4, in the embodiment of the present application, the first storage bit and the third storage bit may be one or multiple, and the number of the first storage bit and the third storage bit is not limited in the embodiment of the present application.
It is understood that if the logical operation result of the binary number shifted from the first storage bit and the binary number shifted from the second storage bit is used as the value of the third storage bit, the pseudo-random characteristic of the binary number sequence stored in the shift register with the preset number of bits can be further improved, the different characteristic patterns generated by different users can be further ensured, and the user collision problem can be further avoided.
Optionally, in another embodiment of the present application, after the step 103 and before the step 104, the method for generating a user characteristic pattern provided in the embodiment of the present application may further include:
and taking the logic operation result of the read one-bit binary number and the shifted binary number of the fourth storage bit as the value of the first storage bit of the shift register with the preset bit number.
And the fourth storage bit is a storage bit except the first storage bit in the shift register with the preset bit number.
Also, in this embodiment, the logical operations may also include, but are not limited to: and operation, or operation and exclusive or operation.
Also as shown in fig. 4, it is assumed that the shift register with the predetermined number of bits is a 19-bit (N-19) right shift register 4, and the first storage bit is D1Then the fourth stored bit may be D2To D19Any one of which stores a bit. Specifically, in FIG. 4, D is19As a fourth storage bit, when the binary number generated from the above step 102 is usedReading a binary digit D in a sequence of words0After being input into the shift register 4, D can be shifted to the right0And D19Exclusive OR operation of shifted-out values with the result D1The value is obtained.
It is understood that if the logical operation result of the read one-bit binary number and the binary number shifted out from the fourth storage bit is used as the value of the first storage bit of the shift register with the preset bit number, the pseudo-random characteristic of the binary number sequence stored in the shift register with the preset bit number can be further improved, the characteristic patterns generated by different users can be better ensured to be different from each other, and the user collision problem can be better avoided.
It should be noted that the logic operation manner shown in fig. 4 is only an example, and those skilled in the art may expand more forms of logic operation manners according to the inventive concept of the embodiment of the present application, and the manner shown in fig. 4 does not limit the protection scope of the user feature pattern generation method provided by the embodiment of the present application.
Corresponding to the above method embodiment, the present application further provides a user characteristic pattern generating device, and the following description is made with reference to the accompanying drawings.
As shown in fig. 5, a user characteristic pattern generating apparatus 500 provided in an embodiment of the present application may include: an acquisition module 501, a copy module 502, an input module 503, and a generation module 504.
The obtaining module 501 is configured to obtain an identity of a target user, where the identity is a binary string.
The copying module 502 is configured to copy the binary digit string according to a preset manner, so as to generate a binary digit sequence.
An input module 503, configured to read a binary digit of one bit from the generated binary digit sequence in sequence at a preset time interval and input the binary digit into a shift register with a preset number of bits.
In one embodiment, when the shift register of the binary number read by the input module 503 is the leftmost shift register, all the shift registers of the predetermined number of bits are shifted to the right by one bit when the binary number is read.
In another embodiment, when the input module 503 reads the binary data from the shift register of the last bit, the shift registers of the predetermined number of bits are all shifted by one bit to the left when reading the binary data.
A generating module 504, configured to generate the feature pattern of the target user according to the binary digit sequence stored in the shift register with the preset number after the binary digit is read.
Specifically, the generating module 504 may be configured to determine a binary digit sequence stored in the shift register with the preset number of bits as the characteristic pattern of the target user.
The specific generating module 504 may be configured to generate the feature pattern of the target user according to the binary digit sequence stored in the shift register with the preset number when each storage bit of the shift register with the preset number of bits stores a binary digit.
According to the user characteristic pattern generation device provided by the embodiment of the application, because a binary number is read from a binary number sequence obtained by copying a binary number string representing the user identity, a shift register with preset digits is input to obtain the characteristic pattern of a target user, and the binary number strings representing different user identities are different, different characteristic patterns can be generated aiming at different users, so that the problem of user collision is not easy to occur.
In addition, because the binary number is read from the generated binary number sequence and the shift register with the preset number of bits is input continuously according to the preset time interval, the characteristic pattern of the target user can be ensured to change along with the change of time instead of being kept unchanged all the time, and the target user can better resist the selective fading of the channel, thereby improving the performance of the system.

The first storage bit and the third storage bit are two adjacent storage bits in the shift register with the preset number of bits, and the second storage bit is a storage bit behind the third storage bit in the shift register with the preset number of bits.
It is easy to understand that if the logical operation result of the binary number shifted from the first storage bit and the binary number shifted from the second storage bit is used as the value of the third storage bit, the pseudo-random characteristic of the binary number sequence stored in the shift register with the preset number of bits can be further improved, the characteristic patterns generated by different users can be ensured to be different from each other, and the user collision problem can be better avoided.

And the fourth storage bit is a storage bit except the first storage bit in the shift register with the preset bit number.
It is understood that if the logical operation result of the read one-bit binary number and the binary number shifted out from the fourth storage bit is used as the value of the first storage bit of the shift register with the preset bit number, the pseudo-random characteristic of the binary number sequence stored in the shift register with the preset bit number can be further improved, the characteristic patterns generated by different users can be better ensured to be different from each other, and the user collision problem can be better avoided.
