Technical field

The present invention relates to the field of wireless communications, and in particular to a scrambling method that can be used in a wireless communication system, a method for transmitting a Radio Network Temporary Identity (RNTI), and a corresponding apparatus.

Background technique

In the existing communication system, multiple RNTIs use the same scrambling method. For example, at the transmitting end, regardless of which RNTI is used for scrambling, a cyclic redundancy check (CRC) bit sequence is first added to the information bit sequence, and then the CRC bit sequence is scrambled using one RNTI to obtain the scrambled CRC bits. The sequence, which in turn encodes the information bit sequence and the scrambled CRC bit sequence to generate a codeword bit sequence, and finally transmits the codeword bit sequence. Correspondingly, after receiving the codeword bit sequence, the receiving end first decodes the codeword bit sequence to obtain an information bit sequence and a scrambled CRC bit sequence. Since the receiving end cannot determine which RNTI the transmitting end uses for scrambling, the receiving end uses multiple RNTIs to descramble the scrambled CRC bit sequence, and determines the information bit sequence and the CRC bit sequence obtained by descrambling. Whether the CRC check is satisfied. And, until the receiving end judges that the information bit sequence and the CRC bit sequence obtained by descrambling satisfy the CRC check, the RNTI adopted by the transmitting end can be determined.

Furthermore, the user terminals described herein may include various types of user terminals, such as mobile terminals (or mobile stations) or fixed terminals, however, for convenience, the UE and the mobile station are sometimes used interchangeably in the following. .

Hereinafter, a scrambling method according to an embodiment of the present invention will be described with reference to FIG. 1. FIG. 1 shows a flow chart of a scrambling method 100.

As shown in FIG. 1, in step S101, a target RNTI is selected from a plurality of candidate RNTIs. In this embodiment, the RNTI may be used as the identifier of the UE inside the signal information between the UE and the access network. According to an example of the embodiment, the target RNTI may be selected from a plurality of candidate RNTIs according to the type of information. For example, multiple candidate RNTIs may correspond to multiple types of information. When scrambling a certain type of information, an RNTI corresponding to the type of the information may be selected as the target RNTI.

For example, the plurality of candidate RNTIs may include C-RNTI, RA-RNTI, S-RNTI, P-RNTI, TPC-RNTI, Temp C-RNTI, and SPS C-RNTI. These candidate RNTIs may respectively correspond to information for dynamically scheduled PDSCH transmission, information for random access response, information for identifying transmission of SIB messages, information for identifying transmission of paging messages, for identifying a joint Information of a user group that encodes a TPC command transmission, information for transmission and collision resolution of Msg3, information for PDSCH transmission for semi-persistent scheduling, and the like. Specifically, for example, when scrambling information for PDSCH transmission for dynamic scheduling, the C-RNTI may be selected as the target RNTI.

Then, in step S102, the scrambling mode corresponding to the target RNTI is determined according to the target RNTI. In this embodiment, when the scrambling mode corresponding to the target RNTI is determined according to the target RNTI, the scrambling mode corresponding to the target RNTI may be selected from the plurality of candidate scrambling modes. For example, for an information bit sequence, some operations may be performed on the information bit sequence before the information bit sequence is transmitted, and a plurality of candidate scrambling modes may be determined according to the location at which the operations are performed.

Specifically, according to an example of the embodiment, the scrambling method 100 shown in FIG. 1 may further include: obtaining an information bit sequence; and performing adding a cyclic redundancy check (CRC) bit sequence, CRC interleaving on the information bit sequence One or more operations in polarization coding, rate matching interleaving. A variety of candidate scrambling modes can be obtained based on one or more operations performed on the sequence of information bits.

2 shows a schematic diagram of operations performed on an information bit sequence in accordance with one embodiment of the present invention. As shown in FIG. 2, first, a CRC bit sequence (for example, length (K ₁ -K)) is added to an information bit sequence (for example, length K) to obtain a bit sequence including redundant bits (for example, the length is K ₁ ). Then, the bit sequence containing the redundant bits is subjected to CRC interleaving to obtain an interleaved bit sequence (for example, the length is K ₁ ). The interleaved bit sequence is then subjected to basic Polar encoding to obtain a polarized code mother codeword bit sequence (e.g., length N). Then, after performing rate matching interleaving on the coded codeword bit sequence, a bit sequence after the rate matching interleaving (for example, length N) is obtained. The rate matched interleaved bit sequence is then cyclically buffered, such as punctured, shortened, repeated, etc., to obtain a rate matched bit sequence (eg, length M).

Accordingly, according to the operations performed on the information bit sequence described above, various candidate scrambling modes obtainable include: scrambling the information bit sequence, scrambling the CRC bit sequence, and at least part of the bits in the interleaved bit sequence Perform scrambling to scramble the frozen bit sequence, the padding bit sequence, or the shortened bit sequence used in the basic polarization encoding of the interleaved bit sequence, and scramble the bit coded bit code sequence of the polarization code mother code at a rate Matching at least one of the interleaved bit sequences for scrambling. Therefore, the scrambling mode corresponding to the target RNTI can be selected from among the plurality of candidate scrambling modes.

According to an example of the embodiment, each of the plurality of candidate RNTIs corresponds to at least one scrambling mode. For example, at least one of the plurality of candidate scrambling modes described above may be selected as the scrambling mode corresponding to each RNTI.

According to another example of the present embodiment, not only each of the plurality of candidate RNTIs corresponds to at least one scrambling mode, but at least two of the plurality of candidate RNTIs respectively have different scrambling modes. For example, the multiple candidate RNTIs are C-RNTI, S-RNTI, and SPS-RNTI, where the C-RNTI may correspond to a scrambling manner in which the information bit sequence is scrambled, and the S-RNTI and the SPS-RNTI may both correspond to the CRC bits. The scrambling method in which the sequence is scrambled. For another example, the plurality of candidate RNTIs are C-RNTI, S-RNTI, and SPS-RNTI, where the C-RNTI may correspond to a scrambling method for scrambling the information bit sequence and a scrambling method for scrambling the CRC bit sequence. The S-RNTI may correspond to a scrambling method for scrambling the CRC bit sequence, and the SPS-RNTI may correspond to a scrambling method for scrambling the information bit sequence.

Then, in step S103, the first bit sequence is scrambled according to the determined scrambling manner to obtain a scrambled bit sequence. For example, in the above-described example as shown in FIG. 2, an operation of adding a cyclic redundancy check (CRC) bit sequence, CRC interleaving, polarization encoding, and rate matching interleaving may be sequentially performed on the information bit sequence. Therefore, when no operation is performed on the information bit sequence, the first bit sequence may be an information bit sequence; when an operation of adding a CRC bit sequence is performed on the information bit sequence, the first bit sequence may also be a CRC added to the information bit sequence. a bit sequence; when performing an operation of adding a CRC bit sequence and a CRC interleave to the information bit sequence, the first bit sequence may also be an interleaved bit sequence; when adding a CRC bit sequence, CRC interleaving, and polarization encoding to the information bit sequence In operation, the first bit sequence may also be a polarization code mother code codeword bit sequence; when performing an operation of adding a CRC bit sequence, CRC interleaving, polarization coding, and rate matching interleaving to the information bit sequence, the first bit sequence is further The interleaved bit sequence can be matched for rate.

Further, according to an example of the embodiment, when the scrambling mode determined in step S102 is one, the first bit sequence can be scrambled using the scrambling method in step S103. According to another example of the present embodiment, when the scrambling manner determined in step S102 is plural, the first bit sequence may be scrambled using only one of the plurality of scrambling modes in step S103.

Alternatively, when the scrambling manner determined in step S102 is multiple, the first bit sequence may be scrambled simultaneously using the multiple scrambling modes in step S103. For example, the intermediate bit sequence corresponding to the first bit sequence and the first bit sequence may be scrambled separately using the plurality of scrambling modes, wherein the intermediate bit sequence refers to an operation performed to generate the first bit sequence The generated bit sequence.

For example, when the scrambling mode determined in step S102 is two, scrambling the information bit sequence and scrambling the CRC bit sequence, respectively, and when the first bit sequence in step S103 is a CRC bit sequence, first The information bit sequence (i.e., the intermediate bit sequence corresponding to the CRC bit sequence) can be scrambled. In addition, the information bit sequence is scrambled to generate a scrambled information bit sequence, and when the CRC bit sequence is added to the scrambled information bit sequence, a CRC bit sequence can be obtained, and the CRC obtained at this time can be obtained. Perform scrambling.

Here, only an example in which the scrambling mode determined in step S102 is two and the first bit sequence in step S103 is a CRC bit sequence is described, but the present invention is not limited thereto. It can be understood that when the scrambling mode determined in step S102 is three or more and the first bit sequence in step S103 is an interleaved bit sequence, a polarized code mother code code word bit sequence or a rate matching interleaved bit The same principle applies to sequences. I will not repeat them here.

Further, according to another example of the present embodiment, the number of bits included in the target RNTI may be the same as or different from the number of bits included in the first bit sequence. In this case, the scrambling method 100 shown in FIG. 1 may further include: processing, according to a function, a bit included in the target RNTI to generate a modified RNTI, where the number of bits included in the modified RNTI and the number of bits A bit sequence contains the same number of bits.

For example, the number of bits included in the target RNTI may be the same as the number of bits included in the first bit sequence. In this case, for example, the first bit sequence can be scrambled directly using the target RNTI. For another example, the bits included in the target RNTI may be randomized according to the randomization function to generate a randomized RNTI (ie, modified RNTI), and the number of bits included in the randomized RNTI is compared with the first bit sequence. The number of bits included is still the same, and then the first bit sequence is scrambled using a randomized RNTI.

For example, the number of bits included in the target RNTI may be less than the number of bits included in the first bit sequence. In this case, the target RNTI may be extended using an extension function to generate an extended RNTI (ie, modified RNTI), and the number of bits included in the extended RNTI is the same as the number of bits included in the first bit sequence. of. For example, the extension function may be to zero-pad the target RNTI, and by zero padding, the number of bits included in the extended RNTI is the same as the number of bits included in the first bit sequence. The first bit sequence is then scrambled using the extended RNTI.

For example, the number of bits included in the target RNTI may be greater than the number of bits included in the first bit sequence. In this case, the shortening function can be used to shorten the target RNTI to generate a shortened RNTI (ie, modified RNTI), and the shortened RNTI includes the same number of bits as the first bit sequence. of. For example, the shortening function may generate a shortened RNTI for selecting a partial bit in the target RNTI according to a predetermined rule, such that the shortened RNTI includes the same number of bits as the first bit sequence. The first bit sequence is then scrambled using the shortened RNTI.

Moreover, according to another example of the embodiment, the scrambling the first bit sequence according to the determined scrambling manner in step S103 may further include: scrambling the first bit sequence by using the target RNTI as a whole. For example, if the bit length of the target RNTI and the bit length of the first bit sequence are both 16 bits, the first to 16 bits included in the target RNTI may be simultaneously performed with the first to 16 bits included in the first bit sequence. Modular addition to achieve scrambling of the first bit sequence.

In addition, according to another example of the embodiment, the scrambling the first bit sequence according to the determined scrambling manner in step S103 may further include: dividing the target RNTI to generate multiple parts of the target RNTI; The first bit sequence is divided to generate a plurality of portions of the first bit sequence; and the plurality of portions of the first bit sequence are separately added according to a plurality of portions of the target RNTI and a scrambling manner corresponding to the target RNTI Disturb. For example, if the bit length of the target RNTI and the bit length of the first bit sequence are both 16 bits, the target RNTI may be divided to generate 16 parts of the target RNTI, and each part includes 1 bit; A bit sequence is divided to generate 16 parts of the first bit sequence, and each part includes 1 bit; then, using the first to the 16th parts of the target RNTI and the scrambling method corresponding to the target RNTI respectively The first to the 16th portions of a bit sequence are subjected to modulo two addition to achieve scrambling of the first bit sequence. With this example, the receiving end can be configured to descramble the received bit sequence as a whole, and to determine whether the partial bit is descrambled or not. It can be verified (such as CRC check), if not, the remaining bits of the received bit sequence can be terminated, thereby achieving early termination of decoding.

Steps S101 to S103 of the scrambling method 100 shown in Fig. 1 have been described above. According to another example of the embodiment, after step S103, the scrambling method 100 as shown in FIG. 1 may further include: encoding the scrambled bit sequence to obtain a codeword bit sequence; and transmitting the codeword bit sequence. In this example, the coding method used may be various coding methods in the prior art, such as a forward error correction code, a convolutional code, etc., which is not limited by the present invention.

According to the scrambling method of the above aspect of the present invention, by scrambling, each of the plurality of RNTIs has a scrambling mode corresponding thereto, and the first bit sequence is performed using the scrambling method corresponding thereto The scrambling is performed to determine the RNTI and the corresponding descrambling mode according to the received bit sequence, and it is no longer necessary to use multiple RNTIs to try to descramble, thereby avoiding waste of time resources and frequency resources and saving power consumption. .

Hereinafter, a descrambling method corresponding to the scrambling method 100 shown in FIG. 1 according to an embodiment of the present invention will be described with reference to FIG. FIG. 3 shows a flow chart of the disturbance aware method 300.

As shown in FIG. 3, in step S301, a codeword bit sequence is received. In this embodiment, the received codeword bit sequence may be a bit sequence generated by encoding the scrambled bit sequence obtained by the scrambling method 100 shown in FIG.

Then, in step S302, the target RNTI and the descrambling mode corresponding to the target RNTI are determined according to the codeword bit sequence. In this embodiment, the target RNTI and the descrambling mode corresponding to the target RNTI may be determined according to the format of the codeword bit sequence. For example, in the scrambling method 100 shown in FIG. 1, each of the plurality of RNTIs has a scrambling mode corresponding thereto, and therefore, the first is performed according to each RNTI and a corresponding scrambling method thereof. The scrambling bit sequence obtained by scrambling the bit sequence has a predetermined format. In this case, the encoded bits received in step S301 also have a predetermined format. Then, in step S302, the target RNTI employed in the scrambling method 100 shown in FIG. 1 and the corresponding descrambling manner may be determined according to the format of the codeword bit sequence.

Then, after step S302, the descrambling method 300 shown in FIG. 3 may further include: before decoding at least part of the bits of the codeword bit sequence, the codeword bit sequence may be solved according to the determined descrambling manner. Disturb. For example, when a partial bit in a codeword bit sequence is decoded to obtain a partially decoded bit sequence, the partially decoded bit sequence is descrambled according to the determined descrambling manner. In this way, it can be determined whether the partially decoded bit sequence passes the check (such as CRC check), and if not, the decoding of the remaining bits in the codeword bit sequence can be terminated, and the early termination of the decoding is achieved.

As another example, the codeword bit sequence can be descrambled prior to decoding the codeword bit sequence. In this way, it can be determined whether the codeword bit sequence passes the check, and if not, the decoding of the codeword bit sequence can be terminated, and the early termination of the decoding is achieved.

In this embodiment, when descrambling, determining the RNTI and the corresponding descrambling manner according to the received codeword bit sequence, and decoding the codeword bit sequence or before decoding the codeword bit sequence, Perform descrambling and determine whether the codeword bit sequence passes the check, instead of descrambling after decoding the codeword bit sequence and determining whether the received bit sequence passes the check, so that the judgment may be advanced when the check is not passed. Terminate decoding.

According to the descrambling method of the above aspect of the present invention, since each RNTI of the plurality of RNTIs has a scrambling mode corresponding thereto at the time of scrambling, and the first bit sequence is performed using the scrambling method corresponding thereto The scrambling is performed to determine the RNTI and the corresponding descrambling mode according to the received bit sequence, and it is no longer necessary to use multiple RNTIs to try to descramble, thereby avoiding waste of time resources and frequency resources and saving power consumption. .

It has been described above that multiple scrambling methods can be used for scrambling for multiple candidate RNTIs. However, for multiple candidate RNTIs having the same bit value on a particular bit, the same scrambling method can be used for scrambling.

Hereinafter, another scrambling method according to an embodiment of the present invention will be described with reference to FIG. FIG. 4 shows a flow chart of the scrambling method 400.

As shown in FIG. 4, in step S401, a target RNTI is selected from a plurality of candidate RNTIs, wherein each of the plurality of candidate RNTIs has the same bit value on a specific bit. For example, the position and value of the partial bits included in each of the plurality of candidate RNTIs are the same. For example, if each of the plurality of candidate RNTIs includes 32 bits, the values of the first to the 16th bits included in each RNTI are the same.

In this embodiment, the target RNTI may be selected from multiple RNTIs having the same bit value on the specific bit, and the target RNTI is used for scrambling, so that the descrambling may be used to perform descrambling and determining Whether a part of the received bit sequence passes a check (such as a CRC check), and the received bit sequence can be decoded early in advance when the decision is not passed.

In this embodiment, the multiple candidate RNTIs may be C-RNTI, RA-RNTI, S-RNTI, P-RNTI, TPC-RNTI, Temp as shown in the above description of the scrambling method 100 shown in FIG. C-RNTI and SPS C-RNTI, etc. Alternatively, the multiple candidate RNTIs may also be RNTIs formed by combining parts in C-RNTI, RA-RNTI, S-RNTI, P-RNTI, TPC-RNTI, Temp C-RNTI, and SPS C-RNTI. .

According to an example of the present embodiment, when a plurality of candidate RNTIs belong to a plurality of users, the location of the specific bit may be different from the location of the specific bit when the candidate RNTI belongs to each user. For example, it is assumed that each of the plurality of candidate RNTIs includes 32 bits, and when the plurality of candidate RNTIs are used for a common serach space of a plurality of users, the location of the specific bits may be The first to 16 bits included in the RNTI, and when a plurality of candidate RNTIs are used for each user's dedicated search space (UE specific serach space), the position of the specific bit may be the 17th to the RNTI 32 bits.

According to another example of the present embodiment, when a plurality of candidate RNTIs belong to a plurality of users, the bit value of the specific bit may be different from the bit value of the specific bit when the candidate RNTI belongs to each user. For example, it is assumed that each of the plurality of candidate RNTIs includes 32 bits, and when a plurality of candidate RNTIs are used for a common search space of a plurality of users, the bit value of the specific bit may be 16 with the S-RNTI. The bit values are the same, and when a plurality of candidate RNTIs are used for each user's dedicated search space, the bit value of the specific bit may be the same as the 16 bit values of the C-RNTI.

According to another example of the present embodiment, when a plurality of candidate RNTIs belong to a plurality of users, the position and bit value of the specific bit and the position and bit value of the specific bit may be different when the candidate RNTI belongs to each user. For example, assuming that each of the plurality of candidate RNTIs includes 32 bits, and when the plurality of candidate RNTIs are used in a common search space of a plurality of users, the location of the specific bits may be included in each RNTI. The 1st to 16th bits and the bit value may be the same as the 16 bit values of the S-RNTI, and when a plurality of candidate RNTIs are used for each user's dedicated search space, the location of the specific bit may be included in each RNTI The 17th to 32th bits and the bit value may be the same as the 16 bit values of the C-RNTI.

Then, in step S402, the first bit sequence is scrambled according to the target RNTI to obtain a scrambled bit sequence. According to an example of the embodiment, the scrambling manners corresponding to the plurality of candidate RNTIs may be the same. The scrambling method described herein may be one of scrambling modes selected from a plurality of candidate scrambling modes. The plurality of candidate scrambling modes are the same as the plurality of candidate scrambling methods involved in describing the scrambling method 100 shown in FIG. 1 above. I will not repeat them here.

Further, in the above-described example as shown in FIG. 2, an operation of adding a CRC bit sequence, CRC interleaving, polarization encoding, rate matching interleaving may be sequentially performed on the information bit sequence. Therefore, when no operation is performed on the information bit sequence, the first bit sequence may be an information bit sequence; when an operation of adding a CRC bit sequence is performed on the information bit sequence, the first bit sequence may also be a CRC added to the information bit sequence. a bit sequence; when performing an operation of adding a CRC bit sequence and a CRC interleave to the information bit sequence, the first bit sequence may also be an interleaved bit sequence; when adding a CRC bit sequence, CRC interleaving, and polarization encoding to the information bit sequence In operation, the first bit sequence may also be a polarization code mother code codeword bit sequence; when performing an operation of adding a CRC bit sequence, CRC interleaving, polarization coding, and rate matching interleaving to the information bit sequence, the first bit sequence is further The interleaved bit sequence can be matched for rate.

Further, according to another example of the present embodiment, the number of bits included in the target RNTI may be the same as or different from the number of bits included in the first bit sequence. In this case, the scrambling method 400 shown in FIG. 4 may further include: processing, according to a function, a bit included in the target RNTI to generate a modified RNTI, where the modified RNTI includes the number of bits and the number of bits. A bit sequence contains the same number of bits.

Moreover, according to another example of the embodiment, the scrambling the first bit sequence according to the target RNTI in step S402 may further include: scrambling the first bit sequence by using the target RNTI as a whole. For example, if the bit length of the target RNTI and the bit length of the first bit sequence are both 16 bits, the first to 16 bits included in the target RNTI may be simultaneously performed with the first to 16 bits included in the first bit sequence. Modular addition to achieve scrambling of the first bit sequence.

In addition, according to another example of the embodiment, the scrambling the first bit sequence according to the target RNTI in step S402 may further include: dividing the target RNTI to generate multiple parts of the target RNTI; Dividing to generate a plurality of portions of the first bit sequence; and scrambling a plurality of portions of the first bit sequence according to a plurality of portions of the target RNTI and a scrambling manner corresponding to the target RNTI. For example, if the bit length of the target RNTI and the bit length of the first bit sequence are both 16 bits, the target RNTI may be divided to generate 16 parts of the target RNTI, and each part includes 1 bit; A bit sequence is divided to generate 16 parts of the first bit sequence, and each part includes 1 bit; then, the first to the 16th parts of the target RNTI and the scrambling modes corresponding to the target RNTI are respectively used The first to the 16th portions of a bit sequence are subjected to modulo two addition to achieve scrambling of the first bit sequence. With this example, the receiving end can be configured to descramble the received bit sequence as a whole, and to determine whether the partial bit is descrambled or not. It can be verified (such as CRC check), if not, the remaining bits of the received bit sequence can be terminated, thereby achieving early termination of decoding.

Steps S401 to S402 of the scrambling method 400 shown in Fig. 4 have been described above. According to another example of the present embodiment, after step S402, the scrambling method 400 as shown in FIG. 4 may further include: encoding the scrambled bit sequence to obtain a codeword bit sequence; and transmitting the codeword bit sequence. In this example, the coding method used may be various coding methods in the prior art, such as a forward error correction code, a convolutional code, etc., which is not limited by the present invention.

According to the scrambling method of the above aspect of the present invention, the target RNTI may be selected from a plurality of RNTIs having the same bit value on a specific bit, and scrambled using the target RNTI, so that the specific bit may be used first in descrambling The descrambling avoids the waste of time resources and frequency resources and saves power consumption.

Hereinafter, a descrambling method corresponding to the scrambling method 400 shown in FIG. 4 according to an embodiment of the present invention will be described with reference to FIG. FIG. 5 shows a flow chart of the disturbance aware method 500.

As shown in FIG. 5, in step S501, a codeword bit sequence is received. In this embodiment, the received codeword bit sequence may be a bit sequence generated by encoding the scrambled bit sequence obtained by the scrambling method 400 shown in FIG.

Then, in step S502, a partial bit in a codeword bit sequence with a specific bit pair of one RNTI is used, wherein the RNTI is one of a plurality of candidate RNTIs, and each of the plurality of candidate RNTIs Have the same bit value on a particular bit. In this embodiment, since each of the plurality of candidate RNTIs has the same bit value on a specific bit, after receiving the scrambled bit sequence, before decoding at least part of the bits of the codeword bit sequence, The partial bit of the codeword bit sequence may be descrambled first by using a specific bit, and then whether part of the bit of the codeword bit sequence passes the check (such as CRC check), and if not, the code bit sequence may be terminated. Decoding of the remaining bits. In this way, it can be determined whether the codeword bit sequence passes the check, and if not, the decoding of the codeword bit sequence can be terminated, and the early termination of the decoding is achieved.

In this implementation, the target RNTI may be selected from multiple RNTIs having the same bit value on a specific bit, and the target RNTI is used for scrambling, so that the descrambling may be used to descramble the first bit and determine the reception. Whether a part of the bits in the received bit sequence passes a check (such as a CRC check), and the received bit sequence can be decoded early in advance when the decision is not passed.

According to the descrambling method of the above aspect of the present invention, since the target RNTI is selected from a plurality of RNTIs having the same bit value on a specific bit at the time of scrambling, and the target RNTI is used for scrambling, the descrambling may be performed first. The specific bit is used for descrambling, which avoids waste of time resources and frequency resources, and saves power consumption.

It has been described above that for a plurality of candidate RNTIs, different scrambling methods can be used for scrambling, and for a plurality of candidate RNTIs having the same bit value on a specific bit, the same scrambling method can be used for scrambling. The method can be seen as implicitly transmitting the RNTI and additionally transmitting the RNTI explicitly.

As shown in FIG. 6, in step S601, a corrected information bit sequence is generated based on the RNTI and the initial information bit sequence. In this embodiment, the initial information bit sequence may be the information bit sequence as shown in FIG. 2 described above.

According to an example of the embodiment, in the modified information bit sequence, the position of the bit included in the RNTI precedes the position of at least a portion of the bit in the information bit sequence. For example, in the modified information bit sequence, the position of the bits included in the RNTI may precede the position of all bits included in the information bit sequence. For example, if the bit length of the RNTI is 16 bits and the bit length of the information bit sequence is 32 bits, the bit length of the modified information bit sequence is 48 bits, and the first to 16 bits of the modified information bit sequence can be It is 16 bits of the RNTI, and the 17th to 48th bits of the modified information bit sequence may be 32 bits of the information bit sequence.

For another example, in the modified information bit sequence, the position of the bit included in the RNTI may precede the position of the partial bit included in the information bit sequence.

Hereinafter, a scrambling apparatus that performs the method 100 shown in FIG. 1 according to an embodiment of the present invention will be described with reference to FIG. FIG. 8 shows a block diagram of a scrambling device 800 that performs the method 100 of FIG.

As shown in FIG. 8, the scrambling device 800 includes a selection unit 810 configured to select a target RNTI from a plurality of candidate RNTIs. The scrambling device 800 further includes a determining unit 820 configured to determine a scrambling mode corresponding to the target RNTI according to the target RNTI. The scrambling device 800 further includes a scrambling unit 830 configured to scramble the first bit sequence according to the determined scrambling manner to obtain a scrambling bit sequence. The scrambling device 800 may include other components in addition to the three units, however, since these components are not related to the content of the embodiment of the present invention, the illustration and description thereof are omitted herein. Further, since the specific details of the operations described below performed by the scrambling device 800 according to the embodiment of the present invention are the same as those described above with reference to FIG. 2, repeated description of the same details is omitted herein to avoid redundancy.

In this embodiment, the RNTI may be used as the identifier of the UE inside the signal information between the UE and the access network. According to an example of the embodiment, the target RNTI may be selected from a plurality of candidate RNTIs according to the type of information. For example, multiple candidate RNTIs may correspond to multiple types of information. When scrambling a certain type of information, an RNTI corresponding to the type of the information may be selected as the target RNTI.

Specifically, according to an example of the embodiment, the scrambling method 100 shown in FIG. 1 may further include: obtaining an information bit sequence; and performing adding a cyclic redundancy check (CRC) bit sequence, CRC interleaving on the information bit sequence One or more operations in polarization coding, rate matching interleaving. A variety of candidate scrambling modes can be obtained based on one or more operations performed on the sequence of information bits. For example, a plurality of candidate scrambling modes obtainable include: scrambling an information bit sequence, scrambling a CRC bit sequence, scrambling at least a portion of the interleaved bit sequence, and performing a basis on the interleaved bit sequence The frozen bit sequence, the padding bit sequence or the shortened bit sequence used in the polarization coding is scrambled, the coded bit code bit sequence of the coded code code is scrambled, and the bit sequence after rate matching is scrambled At least one. Therefore, the scrambling mode corresponding to the target RNTI can be selected from among the plurality of candidate scrambling modes.

The scrambling unit 830 can then scramble the first bit sequence according to the determined scrambling manner to obtain a scrambled bit sequence. For example, in the above-described example as shown in FIG. 2, an operation of adding a cyclic redundancy check (CRC) bit sequence, CRC interleaving, polarization encoding, and rate matching interleaving may be sequentially performed on the information bit sequence. Therefore, when no operation is performed on the information bit sequence, the first bit sequence may be an information bit sequence; when an operation of adding a CRC bit sequence is performed on the information bit sequence, the first bit sequence may also be a CRC added to the information bit sequence. a bit sequence; when performing an operation of adding a CRC bit sequence and a CRC interleave to the information bit sequence, the first bit sequence may also be an interleaved bit sequence; when adding a CRC bit sequence, CRC interleaving, and polarization encoding to the information bit sequence In operation, the first bit sequence may also be a polarization code mother code codeword bit sequence; when performing an operation of adding a CRC bit sequence, CRC interleaving, polarization coding, and rate matching interleaving to the information bit sequence, the first bit sequence is further The interleaved bit sequence can be matched for rate.

Moreover, according to an example of the embodiment, when the scrambling mode determined by the determining unit 820 is one, the scrambling unit 830 can scramble the first bit sequence using the one scrambling method. According to another example of the embodiment, when the scrambling mode determined by the determining unit 820 is plural, the scrambling unit 830 may scramble the first bit sequence using only one of the plurality of scrambling modes.

Alternatively, when the scrambling mode determined by the determining unit 820 is multiple, the scrambling unit 830 may simultaneously scramble the first bit sequence using the multiple scrambling modes. For example, the intermediate bit sequence corresponding to the first bit sequence and the first bit sequence may be scrambled separately using the plurality of scrambling modes, wherein the intermediate bit sequence refers to an operation performed to generate the first bit sequence The generated bit sequence.

For example, when the determining unit 820 determines two scrambling modes, the information bit sequence is scrambled and the CRC bit sequence is scrambled, and when the first bit sequence is a CRC bit sequence, the information bits can be firstly used. The sequence (i.e., the intermediate bit sequence corresponding to the CRC bit sequence) is scrambled. In addition, the information bit sequence is scrambled to generate a scrambled information bit sequence, and when the CRC bit sequence is added to the scrambled information bit sequence, a CRC bit sequence can be obtained, and the CRC obtained at this time can be obtained. Perform scrambling.

Only an example in which the scrambling mode determined by the determining unit 820 is two and the first bit sequence is a CRC bit sequence is described herein, but the present invention is not limited thereto. It can be understood that when the determining unit 820 determines that the scrambling mode is greater than or equal to three, and when the first bit sequence is an interleaved bit sequence, a polarized code mother code code word bit sequence, or a rate matching interleaved bit sequence, The same principle. I will not repeat them here.

Further, according to another example of the present embodiment, the number of bits included in the target RNTI may be the same as or different from the number of bits included in the first bit sequence. In this case, the scrambling unit 830 may be further configured to process the bits included in the target RNTI according to the function to generate a modified RNTI, wherein the modified RNTI includes the number of bits and the first bit sequence The number of bits is the same.

Moreover, according to another example of the present embodiment, the scrambling unit 830 may be further configured to scramble the first bit sequence as a whole with the target RNTI. For example, if the bit length of the target RNTI and the bit length of the first bit sequence are both 16 bits, the first to 16 bits included in the target RNTI may be simultaneously performed with the first to 16 bits included in the first bit sequence. Modular addition to achieve scrambling of the first bit sequence.

Moreover, according to another example of the present embodiment, the scrambling unit 830 may be further configured to divide the target RNTI to generate a plurality of portions of the target RNTI; divide the first bit sequence to generate the first bit sequence a plurality of portions; and scrambling a plurality of portions of the first bit sequence according to a plurality of portions of the target RNTI and a scrambling manner corresponding to the target RNTI. For example, if the bit length of the target RNTI and the bit length of the first bit sequence are both 16 bits, the target RNTI may be divided to generate 16 parts of the target RNTI, and each part includes 1 bit; A bit sequence is divided to generate 16 parts of the first bit sequence, and each part includes 1 bit; then, the first to the 16th parts of the target RNTI and the scrambling modes corresponding to the target RNTI are respectively used The first to the 16th portions of a bit sequence are subjected to modulo two addition to achieve scrambling of the first bit sequence. With this example, the receiving end can be configured to descramble the received bit sequence as a whole, and to determine whether the partial bit is descrambled or not. It can be verified (such as CRC check), if not, the remaining bits of the received bit sequence can be terminated, thereby achieving early termination of decoding.
