Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.
1. New Radio (NR) Physical Broadcast Channel (PBCH)
As shown in fig. 1 (where horizontal line filled boxes in fig. 1 indicate frequency domain positions where NR-PSS is transmitted, diagonal line filled boxes indicate frequency domain positions where NR-PBCH and PBCH-DMRS are transmitted, and lattice filled boxes indicate frequency domain positions where NR-SSS is transmitted), an NR Synchronization Signal Block (SSB) structure is as follows:
a11, Primary Synchronization Signal (PSS): m sequence of length 127, located at 1stOrthogonal Frequency Division Multiplexing (OFDM), occupies subcarriers 56-182.
A12, Secondary Synchronization Signal (SSS): m sequence of length 127, located at 3rdOFDM, occupies subcarriers 56-182.
A13, PBCH: bandwidth of 20RB, occupies 3 OFDM symbols, including 2ndSymbol, 4ndSymbol and 3rd4 RBs on either side of the symbol. Wherein PBCH Payload (Payload)32 bits, Cyclic Redundancy Check (CRC) 24 bits, transmitting 56 bits of information altogether, occupying 432 Resource Elements (RE) and adopting Quadrature Phase Shift Keying (QPSK)
A14, PBCH-DMRS: the PBCH demodulates the pilot and maps to the PBCH with a frequency domain density of 1/4 (i.e., each PBCH occupies 3 subcarriers).
A15, physical cellIdentity (Physical Cell Identifier, PCI): it is constituted as follows:
Figure BDA0002221669020000041
wherein the content of the first and second substances,
Figure BDA0002221669020000042
there are 1008 PCIs.
The SSB period may be configured as 5ms,10ms,20ms,40ms,80ms,160ms, and the PBCH Transmission Time Interval (TTI) is fixed to 80 ms.
Each cycle may contain 1 or more SSBs, and SSBs in the same cycle are transmitted within a 5ms window. These SS blocks constitute a set of synchronization signal collisions (SS burst sets). The maximum number of SS blocks contained in an SS burst set is related to the carrier frequency, as shown in fig. 2:
a21, when the frequency is less than 3GHz, one SS burst set can contain 4 SS blocks at most; at this time, the SSB index needs 2 bits and is carried in DMRS.
A22, when the carrier frequency range is 3GHz to 6GHz, one SS burst set can contain 8 SS blocks at most; at this time, the SSB index needs 3 bits and is carried in DMRS.
A23, when the carrier frequency range is 6GHz to 52.6GHz, one SS burst set can contain 64 SS blocks at most; at this time, the SSB index requires 6 bits, the 3 Least Significant Bits (LSBs) are carried in DMRS, and the 3 LSBs are carried in PBCH.
When the SSB period is unknown, the user assumes the period to be 20ms, and SSBs with the same index in different periods (20ms) are quasi co-located (QCL). For multiple SSBs of a QCL, users can combine to improve decoding success rate.
Wherein, describing two broadcast channels as QCL means that at least one of their Doppler spread (Doppler spread), Doppler shift (Doppler shift), average gain (average gain), average delay (average delay), delay spread (delay spread) and spatial Rx parameters (spatial Rx parameters) is the same, or quasi co-siting can be defined as: user Equipment (UE, also called terminal) may assume that two broadcast channels of the QCL are consistent with respect to doppler spread, doppler shift, average gain, average delay, and delay spread.
2. Part of the flow in the NR Uu PBCH generation method is as follows:
s11, generating 24 bits by the high layer;
s12, the physical layer generates 8 bit: mainly, timing related information that may change in one TTI80ms, for example, a System Frame Number (SFN) of 1-4LSB, a Most Significant Bit (MSB) of 3 bits of an SSB index (for low frequencies, the 3 bits corresponding to the MSB of 3 bits of the SSB index at high frequencies are not used to carry the SSB index, but are still generated by the physical layer), and a Half Frame Indicator (HFI);
s13, connecting the high-level and physical-level generated bits in series to form a 32-bit payload;
s131, performing first-layer scrambling: part of the physical layer generated bits (i.e. 3MSB SSB index (or 3bit corresponding to low frequency), HFI and 2/3LSB SFN of PBCH) are not scrambled, and the other bits of PBCH payload are partially scrambled;
a1, in the first layer scrambling, a scrambling code sequence is related to the 2/3LSB SFN carried in the PCI and PBCH;
a2, because 2/3LSB SFN is not scrambled for the first time, the 2/3LSB SFN can be determined after PBCH decoding so as to determine the scrambling code of the first layer, and the descrambling can be directly performed without a plurality of assumptions and attempts, so that the complexity is reduced;
s132, generating CRC, and carrying out channel coding on PBCH payload
a1, the basic idea of the first layer scrambling is as follows: the bit parts with different contents of the two SSBs which can be combined are not scrambled, and the parts with the same contents of the two SSBs which can be combined are scrambled; or not scrambling different bit parts of PBCH contents of different SSBs in one TTI, and scrambling the same bit parts of the contents
a2, since the time-dependent bits are not scrambled for the first time, the complexity of descrambling and the complexity of blind detection can be reduced.
S133, performing second-layer scrambling: collective scrambling of channel coded bits
a1, in the second-layer scrambling, the scrambling sequences corresponding to different SSBs are only related to SSB indexes and/or HFIs carried in the PCI and DMRS;
a2, therefore, when the user descrambles for the second time, the second-layer scrambling code sequence can be directly deduced according to the DMRS and the related information obtained in the synchronization signal detection process, and various assumptions and attempts are not needed, thereby reducing the complexity.
S14, QPSK modulation, resource mapping, and the like
The two-layer scrambling design thus ensures that the user can solve out the PBCH with less complexity in a short time.
3. Physical Sidelink Broadcast CHannel (PSBCH) in Long Term Evolution (LTE) Vehicle-to-Everything (V2X)
It should be noted that the direct communication link (Sidelink, SL) may also be referred to as a Sidelink/Sidelink.
In LTE V2X, there are two Primary direct communication link Synchronization Signal (PSSS) symbols and two Secondary direct communication link Synchronization Signal (SSSS) symbols in a subframe, and a single slid (sdss) ID is determined by combining the ID of the PSSS and the ID of the SSSS sequence. In addition, three symbols carry Demodulation Reference signals (DMRSs), six symbols carry PSBCH, and only DMRS sequences on the symbols do not multiplex with PSBCH, and a specific format is shown in fig. 3.
4、Sidelink SSB
The design of the S-SSB (lateral-Synchronization Signal Block) in NR sidelink with Normal Cyclic Prefix (NCP) is tentatively as follows (possible modifications follow), the NR S-SSB period is 160ms, and the number of S-SSBs transmitted in each period is as follows. It can be seen that the S-SSB period, format, number of S-SSBs and NR SSBs are quite different.
The structure of NR S-SSB of A31 and NCP is as shown in FIG. 4. for the ECP, the structure is the same as that in FIG. 4 except that the number of PSBCH symbols after S-SSS is only 6.
A32, the S-SSB period of all SCS supports 160 ms;
a33, configuring the S-SSB transmission times in one S-SSB period (in advance);
for Frequency band 1(Frequency Range 1, FR 1):
when the subcarrier spacing is 15kHz, the transmission times may be {1, [2] };
when the subcarrier spacing is 30kHz, the transmission times may be {1,2, [4] };
the number of transmissions may be {1,2,4, [8] } at a subcarrier spacing of 60 kHz.
For Frequency band 2(Frequency Range 2, FR 2):
when the subcarrier interval is 60kHz, the transmission times can be {1,2,4,8,16,32 };
the number of transmissions may be 1,2,4,8,16,32,64 with a subcarrier spacing of 120 kHz.
Besides NR sidelink, other technologies related to sidelink, such as Network Control Interactive Service (NCIS), etc., may also need to design a sidelink broadcast channel, a sidelink primary synchronization signal, a sidelink secondary synchronization signal, and a sidelink DMRS, and the relative relationship of these signals may be different from or the same as the above NR S-SSB. In addition, other technologies, such as NR unlicensed (NRU) or internet of things (IOT), may also need to design the broadcast channel, and the transmission mode, period, TTI, and structure of the broadcast channel or its signal block may be different from that of NR SSB.
It should be noted that the LSB and the MSB are respectively defined as the least significant bit and the most significant bit. Taking SSB index as an example, assuming that SSB index is indicated by 6 bits, then the binary of the SSB index is 001000, and 3MSB is 3 bits from the left and is 001; the 3LSB is 3 bits from the right, which is 000. In addition, since different encoding habits and manners, the left and right order and the LSB and MSB may be reversed from the above example, or different definitions may exist in different programs, this is not excluded in the embodiments of the present invention.
The invention provides an information sending and receiving method, a control node and a terminal, aiming at the problems that in the communication technology except for an NR Uu interface, broadcast channels of other technologies cannot be generated, scrambled and transmitted along with NR SSB generation, scrambling and transmission flows, so that the network communication flow is incomplete and the communication reliability cannot be ensured.
As shown in fig. 5, an embodiment of the present invention provides an information sending method, applied to a sending end, including:
step 501, generating first information;
the generation method of the first information includes one of the following:
b11, generated by the physical layer;
in this case, it means that all bits in the first information are generated by the physical layer of the transmitting end.
B12, generated by a higher layer;
in this case, it means that all bits in the first information are generated by a higher layer of the transmitting end.
B13, generating partial information by the physical layer and generating partial information by the higher layer;
in this case, the partial bits in the first information are generated by the higher layer of the transmitting end, and the partial bits in the first information are generated by the physical layer of the transmitting end.
Step 502, sending the first information to a receiving end through a broadcast channel;
since the generated first information is information included in a broadcast channel, the transmitting end needs to transmit the broadcast channel carrying the first information to the receiving end.
The sending end in the embodiment of the present invention may be a terminal in direct communication, or may also be a network side device, for example, an access network node in NR unauthorized.
It should be noted that, because the physical layer may generate information of part or all bits in the first information, when the first target information (the first target information includes at least part of bits in the first information) in the first information is generated by the physical layer, at least part of bits in the first target information is determined according to at least one of the following parameters:
b21, quasi co-location parameter;
b22, repetition parameter indicating repetition relation between broadcast channels;
b23, Transmission Time Interval (TTI) of broadcast channel;
b24, period of broadcast channel;
b25, index of target parameter;
it should be noted that the target parameter includes at least one of the following:
b251, a broadcast channel;
b252, a signal block where a broadcast channel is located;
for example, the index of the signal block where the broadcast channel is located may be an S-SSB index, a DRS index, or the like.
B253, time domain resources where the broadcast channels are located;
for example, the index of the time domain resource where the broadcast channel is located may be a slot index, an HFI, and the like.
B26, a first parameter (in the embodiment of the present invention, K is used for the first parameter);
it should be noted that the first parameter is determined by the configuration of the control node, the pre-configuration, the protocol agreement, the indication of other terminals except the sending terminal, or the sending terminal; specifically, the control node may be a network side device, or may also be a direct communication device, for example, a terminal for direct communication, and the control node may also be a roadside terminal.
Further, the determination manner of the first parameter includes one of the following:
b261, determining the ratio of the period of the broadcast channel to the TTI of the broadcast channel as a first parameter;
b262, determining the ratio of the interval time of the broadcast channel to the TTI of the broadcast channel as a first parameter;
it should be noted here that the interval time of the broadcast channel may be the interval frame number of the broadcast channel, for example, 2 frames are interval between two broadcast channels.
And B263, determining the ratio of the interval time of the broadcast channel to the period of the broadcast channel as a first parameter.
B27, number of broadcast channels.
It should be noted that, the first information may include bits related to a frame number (i.e., a system frame number), and/or bits related to an index (it should be noted that, in the embodiment of the present invention, the index refers to at least one of the above B25), and in a case where at least two broadcast channels are quasi co-located (QCL), repeated, or at least partially identical in specific content, the frame number and/or the index may affect the physical layer and the higher layer partitioning, and the following description specifically describes the structure of the first information from the perspective of the frame number and the index, and specifically describes the case where at least two broadcast channels are quasi co-located or the repeated may include before the description.
Assuming that the content of the broadcast channel is X bits (including no CRC), that is, the first information is X bits, when the broadcast channels on different resources (or broadcast channels in different Signal blocks including the broadcast channel, for example, broadcast channels in different synchronization Signal blocks or Discovery Reference Signals (DRSs)) are jointly detectable (for example, when different Signal blocks or broadcast channels satisfy at least one of QCL, repetition, and at least part of specific content is equal, it is considered that joint detection is possible), the receiving end side may combine or jointly detect the broadcast channels, thereby improving the decoding success rate of the content of the broadcast channels. There may be three situations:
case one, at least two broadcast channels in different periods are QCL, repeated or at least partially identical for a specific content
It is assumed that a period of a broadcast channel (or a signal block in which the broadcast channel is located) is P, a TTI of the broadcast channel is T, and at least two broadcast channels located in different periods in the same TTI are QCL, repeated or at least partially identical in specific content, as shown in fig. 6, where T is P × K.
In case two, at least two broadcast channels located in different frames in the same period or in the same TTI are QCLs, 1 repeated or at least partially identical specific content, and it is assumed that the period of a broadcast channel (or a signal block in which the broadcast channel is located) is T, the positions of m broadcast channels (or signal blocks in which the broadcast channel is located) are distributed in a plurality of frames (1 or more broadcast channels or signal blocks may exist in one frame) in the period, and it is assumed that a broadcast channel (or a signal block in which the broadcast channel is located) may exist every P frames, and at least two broadcast channels located in different frames are QCLs, repeated or at least partially identical specific content, specifically, T is P × K. For example, as shown in fig. 7, there are 1 broadcast channel per frame, and the broadcast channel is QCL, repeated, or at least partially identical for certain content between different frames; for example, as shown in fig. 8, there are multiple broadcast channels per frame, and the broadcast channel QCL, repetition, or at least some of the specific content is the same between different frames; specifically, T ═ P × K.
It should be noted that in this case, it may be further possible that broadcast channels exist in multiple periods within one TTI, broadcast channels with the same index during different periods are combinable, for example, the QCL of the broadcast channels with the same index is the same, repeated, or at least partially the specific content is the same, while broadcast channels with different indices during different periods are not combinable, for example, the QCL is different or not repeated or the specific content is different; or broadcast channels with any index in the period or broadcast channels with the same index after a specific calculation (e.g. modulo or division with a specific value) are combinable, e.g. when these broadcast channels QCL are identical, repeated or at least partly identical with a specific content, while broadcast channels during the period are not combinable, e.g. these broadcast channels QCL are different or not repeated or different with a specific content.
It should also be noted that in this case, it may further be the case that there are multiple frames in a period and multiple broadcast channels in a frame, and broadcast channels with the same index between different frames may be merged, for example, QCL is the same, repeated, or at least part of specific content is the same; broadcast channels of different indexes between different frames are not combinable, for example, broadcast channels of different QCLs are different, are not repeated, or have different specific contents, as shown in fig. 9, broadcast channels between different frames can be combinable; or any indexed broadcast channel or index within a frame may be merged after a certain calculation (e.g., modulo or division by a certain value) to result in the same broadcast channel, e.g., QCL is the same, repeated, or at least partially the same content, as shown in fig. 10, the same broadcast channel within the same frame may be merged; intra-frame indices are not combinable, e.g., QCL different, no repetition, or specific content different.
It should also be noted that in this case, it may further be the case that there are multiple periods within one TTI, there are multiple frames in each period, and there are multiple broadcast channels in one frame. The relationship of the broadcast channel at this time may be a combination of the above two cases. For example, broadcast channels in frames with the same position relative to the start of the respective periods in different periods of the same TTI may be merged if the indexes are the same, the index mod M1 is the same, or the index/M2 is the same, e.g., QCL is the same, repeated, or at least partially the specific content is the same. Specifically, for example, broadcast channels with the same index, the same index mod M1, or the same index/M2 in the first frame in period 1 and the first frame in period 2 are QCL; wherein M1 and M2 are one of a quasi co-located parameter, a repetition parameter and a quasi co-located parameter of a repetition relationship between broadcast channels, and a common multiple of a repetition parameter indicating a repetition relationship between broadcast channels, respectively.
In a third case, there are multiple broadcast channels (or signal blocks in which the broadcast channels are located) in the same frame, and at least two of the broadcast channels (or signal blocks in which the broadcast channels are located) are QCLs, 1 with repeated or at least partially identical specific content, the period of the broadcast channel is assumed to be P (or the period of the signal block including the broadcast channel is P), the TTI of the broadcast channel is T, m broadcast channels are distributed in a certain frame of each period, and at least two broadcast channels in the frame are QCLs, repeated or at least partially identical specific content, as shown in fig. 11.
2. Assuming that the period of the broadcast channel is T (or the period of the signal block containing the broadcast channel is T), m broadcast channels are distributed in a plurality of frames of each period, and the distance between the frames containing the broadcast channels is P frames, assuming that at least two broadcast channels in the same frame containing the broadcast channels are QCL, repeated or at least partially identical to specific content, as shown in fig. 12, three broadcast channels in the same frame are QCL, repeated or at least partially identical to specific content.
First, influence of frame number on physical layer and high layer division
1. In case that at least two broadcast channels located between different frames are QCL, repeated, or at least part of specific content is the same
It should be noted that this case mainly refers to the above-mentioned case one and case two, in which case, the broadcast channel is QCL, and the distance between two frames with repeated or at least partially identical specific content is P frames.
Specifically, second target information in the first information is generated by a physical layer, and the second target information includes at least part of bits in the first information.
That is, in this case, the physical layer may generate a part of bits in the first information or may generate all bits.
It should be noted that, in this case, the value of the number of bits of the second target information satisfies: greater than or equal to N and is a multiple of 8;
wherein the content of the first and second substances,
Figure BDA0002221669020000121
i.e. N is log2(P) rounding up to obtain an integer; or
Figure BDA0002221669020000122
Figure BDA0002221669020000123
I.e. N is log2(P) rounding down the resulting integer; p is at least two broadcast channels (it should be noted here that at least two broadcast channels are QCL, repeated or at least partially identical for specific contentBroadcast channel) and, optionally, the number of gap frames.
Further, the second target information at least includes information of X bits of the frame number, that is, the information generated by the physical layer at least includes information of X bits of the frame number.
Specifically, the determination of X includes one of the following:
b31, X bits are the N +1 th to the N + Y th bits of the frame number;
in particular, the amount of the solvent to be used,
Figure BDA0002221669020000124
or
Figure BDA0002221669020000125
P is the interval time between frames where at least two broadcast channels are located,
Figure BDA0002221669020000126
i.e. Y is log2(K) Rounding up to obtain an integer; or
Figure BDA0002221669020000127
I.e. Y is log2(K) Rounding down to obtain an integer; k is a first parameter.
Here, since Y and N are both positive integers, X is also a positive integer.
B32, X bits are N + Y bits of the frame number;
it should be noted that, in this case, X bits shall be at least N + Y bits of the frame number, and X is a positive integer; that is, when N + Y is 3, X should be an integer greater than or equal to 3.
It should be noted that, in this case, the transmitting end scrambles the second target information before performing channel coding on the second target information, and at this time, the scrambling performed on the second target information may be regarded as first-layer scrambling.
In particular, X takes on the value 4, 6 or 10.
Specifically, the implementation manner of scrambling the second target information is as follows:
at least some bits of the information of the X bits in the second target information are not scrambled, or a scrambling sequence or scrambling bits used when at least some bits of the information of the X bits are scrambled is 0.
The above case is exemplified as follows:
for example 1, if the broadcast channel TTI is 640ms and the broadcast channel period P is 160ms, let K be T/P be 4. It is assumed that at least two broadcast channels in different periods are QCL, repeated, or at least partially identical for a specific content. Then Y is equal to log2(K)=2,N=log2(P/10) ═ 4, N + Y ═ 6; the broadcast channel content generation scheme at this time includes:
the bits generated by the physical layer need to contain at least X bits of the frame number.
Optionally, the X bits correspond to bits 5 and 6 of the frame number;
optionally, the bits generated by the physical layer may also include the lowest six bits of the frame number; alternatively, the first and second electrodes may be,
the lowest seven positions; alternatively, the first and second electrodes may be,
a minimum of eight bits; alternatively, the first and second electrodes may be,
the number of bits generated by the physical layer may contain all ten bits of the frame number if it is greater than 8.
It should be noted that the information generated by the physical layer may further include other information, such as HFI, in addition to the frame number information.
Optionally, when the X bits correspond to the 5 th and 6 th bits of the frame number, the transmitting end does not scramble the 5 th and 6 th least significant bit frame numbers when performing the first layer scrambling.
For example 2, if the broadcast channel TTI is 160ms or the broadcast channel period T is 160ms, and it is assumed that at least two broadcast channels located in different frames within one TTI or period of 160ms are QCL, repeated or at least partially identical in specific content, and the time interval between the frames where these broadcast channels are located is P. Let P be 40ms and K be T/P4. Then Y is equal to log2(K)=2,N=log2(P/10) ═ 2, N + Y ═ 4; the broadcast channel content generation scheme at this time includes:
the bits generated by the physical layer need to contain at least X bits of the frame number.
Optionally, the X bits correspond to bits 3 and 4 of the frame number;
optionally, the bits generated by the physical layer include the lowest four bits of the frame number; alternatively, the first and second electrodes may be,
the lowest five bits; alternatively, the first and second electrodes may be,
a minimum of eight bits; alternatively, the first and second electrodes may be,
all ten positions.
It should be noted that the information generated by the physical layer may further include other information, such as HFI, in addition to the frame number information.
Optionally, when the X bits correspond to the 3 rd and 4 th bits of the frame number, the transmitting end does not scramble the 3 rd and 4 th least significant bit frame numbers when performing the first layer scrambling.
For example 3, if the broadcast channel TTI is 160ms and the broadcast channel period T is 160ms, the positions of 8 broadcast channels are distributed in 2 frames in a TTI or period with the length of 160ms, and there may be 2 broadcast channels in one frame every P80 ms, assuming that K is T/P is 2. It is assumed that at least two broadcast channels located in different above frames are QCL, repeated or at least partially identical for a specific content. Then Y is equal to log2(K)=1,N=log2(P/10) ═ 3, N + Y ═ 4; the broadcast channel content generation scheme at this time includes:
the bits generated by the physical layer need to contain at least X bits of the frame number.
Optionally, X bits correspond to the 4 th bit of the frame number;
optionally, the bits generated by the physical layer include the lowest four bits of the frame number; alternatively, the first and second electrodes may be,
the lowest five bits; alternatively, the first and second electrodes may be,
a minimum of eight bits; alternatively, the first and second electrodes may be,
all ten positions.
It should be noted that the information generated by the physical layer may further include other information, such as HFI, in addition to the frame number information.
Optionally, when the X bits correspond to a 4 th bit of the frame number, the transmitting end does not scramble a 4 th least significant bit frame number when performing the first layer scrambling.
2. In case that at least two broadcast channels within the same frame are QCL, repeated or at least partially identical for specific content
This case is mainly the case three described above.
In this case, the first information satisfies one of the following conditions:
b41, third target information in the first information is generated by a physical layer, and bits corresponding to a frame number are not contained in bits of the third target information;
specifically, the third target information includes at least a part of bits in the first information.
In this case, when the first information includes information generated by the physical layer, no bit corresponding to the frame number exists in the information generated by the physical layer.
B42, the first information is generated by a high layer;
it should be noted that, this case means that when any two broadcast channels in the same frame are QCL, duplicate, or at least some specific contents are the same, all contents in the broadcast channels are generated by a higher layer; for example, the indexes are all carried by DMRSs or synchronization sequences, and when any two broadcast channels in the same frame are QCLs, repeated, or at least partially identical to a particular content, all the content in the broadcast channels is generated by higher layers.
It should be noted that, in the embodiment of the present invention, when the first information is generated by a higher layer (that is, all content in a broadcast channel is generated by a higher layer), the first information is scrambled only after the first information is channel-coded.
The above case is exemplified as follows:
for example 1, if the broadcast channel TTI is 160ms or the broadcast channel period is 160ms, and it is assumed that at least two broadcast channels located in the same frame in one TTI or period with a length of 160ms are QCL, repeated or at least partially the specific content is the same, the broadcast channel content generation scheme includes:
at least part of information in the broadcast channel content is generated by a physical layer, and the bits generated by the physical layer do not contain the bits related to the frame number; alternatively, the first and second electrodes may be,
all content in the broadcast channel is high-level generated;
optionally, in this case, when any two broadcast channels within the frame are QCL, duplicate, or at least partially identical to a particular content, all of the content in the broadcast channels is higher layer generated.
For example, if the broadcast channel TTI is 160ms or the broadcast channel period is 160ms, and the locations of 64 broadcast channels are assumed to be distributed in multiple frames within a TTI or period of 160ms, and there may be 16 broadcast channels in a frame every P-40 ms, assuming K-T/P-4. Assuming that at least two broadcast channels located within the same above-mentioned frame are QCL, repetitive or at least partially identical for specific content, the broadcast channel content generation scheme comprises:
at least part of information in the broadcast channel is generated by a physical layer, and the bits generated by the physical layer do not contain the bits related to the frame number; alternatively, the first and second electrodes may be,
all content in the broadcast channel is high-level generated;
optionally, in this case, when any two broadcast channels within the frame are QCL, duplicate, or at least some of the specific content is the same, all of the content in the broadcast channels is higher layer generated.
Second, the impact of indexing on physical layer and higher layer partitioning
1. In case two broadcast channels of arbitrary index are quasi co-located or repeated or at least part of specific content is identical
In this case, the first information satisfies one of the following conditions:
b51, fourth target information in the first information does not contain at least partial bits corresponding to an indication index, and the fifth target information is generated by a physical layer;
that is, in this case, if the first information includes bits generated by the physical layer, the bits generated by the physical layer do not include a part of or all of the bits corresponding to the index. Further, the indexes are all carried by the DMRS or the synchronization sequence, and if there is a physical layer generated bit, the bits do not include a bit corresponding to the index.
Further, the fourth target information needs to be scrambled before channel coding.
B52, the first information is generated by a high layer, and the first information does not contain at least partial bits corresponding to an indication index;
in this case, the content of the broadcast channel is generated by the upper layer of the transmitting end; optionally, the indexes are all carried by DMRS or synchronization sequences, and all content in the broadcast channel is generated by higher layers.
The above case is exemplified as follows:
assuming that the broadcast channel at different periods or different frames or arbitrary indices of the same frame are QCL, repeated or at least partially specific content identical, the physical layer generated part does not contain index related bits if at least part of the broadcast channel content is physical layer generated, or alternatively the broadcast channel content is generated by higher layers.
For example 1, if the broadcast channel TTI is 640ms and the broadcast channel period P is 160ms, let K be T/P be 4. It is assumed that two broadcast channels of arbitrary index in different periods are QCL, repeated, or at least partially identical for a specific content. Then Y is equal to log2(K)=2,N=log2Examples of the value of (P/10) ═ 4, N + Y ═ 6, and not less than N and a multiple of 8 include 8,16 …, and the like. The broadcast channel content generation scheme at this time includes:
at least a portion of the broadcast channel content is physical layer generated;
optionally, the indexes are all carried by the DMRS or the synchronization sequence, and if there is a physical layer generated bit, the physical layer generated bit does not include an index-related bit; further optionally, the physical layer generated bits contain frame number related bits, e.g., the physical layer generated bits need to contain at least the six lowest bits of the frame number, and these bits are not scrambled while the first layer is scrambling code.
Or, if there is a physical layer generated bit, the physical layer generated bit contains at least part of the bits of the index; further optionally, the bits are not scrambled while the first layer scrambling code is scrambled.
Alternatively, all content in the broadcast channel is higher-level generated;
optionally, the indexes are all carried by DMRS or synchronization sequences, and all content in the broadcast channel is generated by higher layers.
For example 2, if the broadcast channel TTI is 160ms or the broadcast channel period T is 160ms, and it is assumed that two broadcast channels with a length of 160ms or any index located in different frames in the period are QCL, repeated or at least partially identical in specific content, and the time interval between the frames where these broadcast channels are located is P. Let P be 40ms and K be T/P4. Then Y is equal to log2(K)=2,N=log2Examples of the value of (P/10) ═ 2 and N + Y ═ 4 include 8 which is not less than N and is a multiple of 8,16 …, and the like. The broadcast channel content generation scheme at this time includes:
at least part of the broadcast channel content is physical layer generated, wherein optionally the index is carried entirely by DMRS or synchronization sequence, and if there is physical layer generated bit, it does not contain index related bit; further optionally, the physical layer generated bits include frame number related bits, for example, the physical layer generated bits need to include at least the lowest four bits of the frame number, and the bits are not scrambled while the first layer is scrambling.
Or, if there are physical layer generated bits, the physical layer generated bits contain at least part of the bits of the index, further optionally, the bits are not scrambled while the first layer scrambling code is scrambled.
Or all content in the broadcast channel is generated by a higher layer, optionally, the indexes are all carried by DMRSs or synchronization sequences, and all content in the broadcast channel is generated by a higher layer.
For example 3, if the broadcast channel TTI is 160ms and the broadcast channel period T is 160ms, the positions of 8 broadcast channels are distributed in 2 frames in a TTI or period with the length of 160ms, and there may be 2 broadcast channels in one frame every P80 ms, assuming that K is T/P is 2. It is assumed that two broadcast channels at different arbitrary indices of the above frames are QCL, repeated, or at least partially identical for a specific content. Then Y is equal to log2(K)=1,N=log2When (P/10) ═ 3, N + Y ═ 4, and the value is not less than N and is a multiple of 8, such as 8,16 …, the broadcast channel content generation scheme includes:
at least part of the broadcast channel content is physical layer generated, wherein optionally the index is carried entirely by DMRS or synchronization sequence, and if there is physical layer generated bit, it does not contain index related bit; further optionally, the physical layer generated bits include frame number related bits, for example, the physical layer generated bits need to include at least the lowest four bits of the frame number, and the bits are not scrambled while the first layer is scrambling.
Or, if there are physical layer generated bits, the physical layer generated bits contain at least part of the bits of the index, further optionally, the bits are not scrambled while the first layer scrambling code is scrambled.
Or all content in the broadcast channel is generated by a higher layer, optionally, the indexes are all carried by DMRSs or synchronization sequences, and all content in the broadcast channel is generated by a higher layer.
For example 4, if the broadcast channel TTI is 160ms or the broadcast channel period is 160ms, and it is assumed that two broadcast channels of one TTI of length 160ms or any index within the same frame within the period are QCL, repeated or at least partially content specific. The broadcast channel content generation scheme at this time includes:
at least part of the broadcast channel content is physical layer generated, optionally the indices are all carried by DMRS or synchronization sequences, and if there are physical layer generated bits, no index related bits are included.
Or, if there are physical layer generated bits, the physical layer generated bits contain at least part of the bits of the index, further optionally, the bits are not scrambled while the first layer scrambling code is scrambled.
Or all content in the broadcast channel is generated by a higher layer, optionally, the indexes are all carried by DMRSs or synchronization sequences, and all content in the broadcast channel is generated by a higher layer.
For example 5, if the broadcast channel TTI is 160ms or the broadcast channel period is 160ms, and it is assumed that 64 broadcast channels are located in multiple frames within one TTI or period with the length of 160ms, and there may be 16 broadcast channels in one frame every P-40 ms, and it is assumed that K-T/P-4. Assuming that two broadcast channels of arbitrary index located in the same above-mentioned frame are QCL, duplicate or at least partially identical to a specific content, the broadcast channel content generation scheme includes:
at least a portion of the broadcast channel content is physical layer generated;
specifically, the indexes are all carried by DMRS or synchronization sequences, and if there are physical layer generated bits, index-related bits are not included.
Or, all contents in the broadcast channel are generated by a higher layer, the indexes are all carried by the DMRS or the synchronization sequence, and all contents in the broadcast channel are generated by the higher layer.
2. In case at least two broadcast channels of the same index are quasi co-located or repeated or at least part of the specific content is the same
In this case, the fifth target information in the first information is generated by the physical layer;
wherein, the fifth target information at least comprises at least part of bits corresponding to the index.
That is, in this case, the physical layer may generate some or all bits in the first information, and the bits generated by the physical layer include some or all bits corresponding to the index.
It should be noted that if FR2 contains Y bits in the corresponding bits of the index, FR1 also contains the Y bits, regardless of whether the Y bits actually carry content or not.
It should be further noted that, before performing channel coding on the fifth target information, the sending end scrambles the fifth target information, and optionally, when the sending end scrambles the fifth target information, the following method may be adopted:
and not scrambling the bits related to the index in the fifth target information, or scrambling the bits related to the index in the fifth target information with a scrambling sequence or scrambling bits of 0.
That is, when scrambling bits generated by the physical layer, the terminal does not scramble bits related to the index among the bits, or a scrambling sequence or a scrambling bit adopted when scrambling bits related to the index among the bits is 0; specifically, when receiving a broadcast channel, a receiving end performs channel decoding on the fifth target information, and then descrambles the fifth target information, specifically, bits related to an index in the fifth target information are not descrambled, or a descrambling sequence or a descrambling bit used when descrambling the bits related to the index is 0.
3. In case that at least two broadcast channels satisfying a first preset condition are quasi co-located or repeated or at least part of specific contents are identical
It should be noted that, in this case, the first preset condition includes at least one of the following conditions:
b61, the index is the same;
b62 and the result obtained by the index mod M1 are the same;
it should be noted that M1 represents one of the following parameters: the quasi co-location parameter, the repetition parameter and the quasi co-location parameter of the repetition relationship between the broadcast channels, and a common multiple of the repetition parameter indicating the repetition relationship between the broadcast channels.
B63 and the result obtained by the index/M2 are the same;
it should be noted that M2 represents one of the following parameters: the quasi co-location parameter, the repetition parameter and the quasi co-location parameter of the repetition relationship between the broadcast channels, and a common multiple of the repetition parameter indicating the repetition relationship between the broadcast channels.
In this case, fifth target information in the first information is generated by a physical layer;
wherein, the fifth target information at least comprises at least part of bits corresponding to the index.
That is, in this case, the physical layer may generate some or all bits in the first information, and the bits generated by the physical layer include some or all bits corresponding to the index.
Further, in the case that at least two broadcast channels with the same result obtained by the index mod M1 are quasi co-located, repeated, or at least partially identical in specific content, the fifth target information at least includes an index

Or

wherein Z is the total number of bits occupied by the index.
It should be noted that the fifth target information at least includes the most significant bit of the index

Or
Figure BDA00022216690200002010
Bits are carried in DMRS.
It should be further noted that, before performing channel coding on the fifth target information, the transmitting end scrambles the fifth target information, and optionally, when the transmitting end scrambles the fifth target information, the following method may be adopted:
and not scrambling the bits related to the index in the fifth target information, or scrambling the bits related to the index in the fifth target information with a scrambling sequence or scrambling bits of 0.
The above case is exemplified as follows:
assuming that broadcast channels of the same index located in different periods or different frames are QCL, repeated or at least partially identical in specific content, the physical layer generates bits of the partial broadcast channels and the physical layer generating part contains at least index related bits:
for example, the physical layer generation part contains at least the upper 3 bits of the index, or contains the lower 3 bits of the index, or contains all the bits of the index.
Example 1, assuming that the broadcast channel with the same value of the index mod M1 located in different periods or in different frames or in the same frame is QCL, repeated or at least partially identical in specific content, indicating that the index requires Z bits in total, the physical layer generates a part of bits of the broadcast channel and the physical layer generated part at least contains bits related to the index, and the part of bits is related to M1:
when the physical layer generating part at least contains the index height

At least a portion of a bit;
further, when the physical layer generation part at least contains the index high

Bit bits, and DMRS carries index low
Figure BDA00022216690200002013
A bit.
Or, the physical layer generates all bits of which part contains the index;
more specifically, assuming that the odd indexed broadcast channel is QCL, repeated or at least partially identical for specific content, and the even indexed broadcast channel is QCL, repeated or at least partially identical for specific content, i.e., M1 ═ 2, if Z ═ 6, then there is a physical layer generation part containing the high 6-1 ═ 5 bits of the index, and the DMRS carries the lowest 1 bit; or the physical layer generation part contains all 6 bits of the index.
More specifically, assuming that M is 4, if Z is 6, there is a physical layer generation part containing high 6-2-4 bits of the index at this time, and the DMRS carries low 2 bits; or the physical layer generation part contains all 6 bits of the index.
Example 2, assuming that the broadcast channel with the same value of index/M2 located in different periods, different frames or the same frame is QCL, repeated or at least partially the same specific content, it indicates that the index requires Z bits in total, when the physical layer generates part of the bits of the broadcast channel and the physical layer generated part at least contains bits related to the index, and the part of the bits is related to M2:
when the physical layer generating part at least contains the index
Figure BDA0002221669020000211
At least a portion of a bit;
further, when the physical layer generation part at least contains the index low
Figure BDA0002221669020000212
Bit bits, and DMRS carries index high
Figure BDA0002221669020000213
A bit.
The physical layer generates part or all of the bits containing the index.
More specifically, assuming that M is 4, if Z is 6, there is a physical layer generating part that at least contains the lower 2 bits of the index, and the DMRS carries the upper 6-2-4 bits of the index; or the physical layer generation part contains all 6 bits of the index.
At this time, optionally, the first scrambling is performed without scrambling the bit portion related to the index generated by the physical layer.
It should be noted that, the first information is generated in a manner that: when the physical layer generates the partial information and the high layer generates the partial information, the bit occupied by the first information satisfies one of the following items:
the number of bits occupied by the partial information generated by the high layer is 24, and the number of bits occupied by the partial information generated by the physical layer is 8;
it should be noted that, assuming that the bit number of the information related to time in the physical layer generation information is 4, the bit number of the physical layer needs to be complemented to 8 to align the bit number, at this time, since the physical layer carries the information related to time, the receiving end can simplify the descrambling flow, which is beneficial to reducing the detection complexity and improving the detection accuracy.
The number of bits occupied by the partial information generated by the high layer and the partial information generated by the physical layer is 16 respectively;
it should be noted that, if the number of bits of the time-related information in the physical layer generation information is 9 (greater than 8), the number of bits of the physical layer needs to be compensated to 16 to align the number of bits, which is beneficial to reducing the detection complexity and improving the detection accuracy.
The division of the upper and physical layers is exemplified as follows.
For example 1, if the broadcast channel TTI is 640ms and the broadcast channel period P is 160ms, let K be T/P be 4. Assuming that the payload of the broadcast channel (i.e., the bits occupied by the content of the broadcast channel) is 32 bits, the broadcast channel content generation scheme comprises:
the high layer generates 24 bits, and the physical layer generates 8 bits;
alternatively, the upper layer generates 16 bits and the physical layer generates 16 bits.
More specifically, for example, in combination with the above-mentioned case that the broadcast channel with the same index is QCL, repeated or at least partially has the same specific content, the physical layer generated bits need to include at least 6 bits of frame number and partial index related bits, and in this case, a possible way is that the physical layer generates 16 bits, 8 bits are respectively 6 bits of frame number LSB and 2 bits of index MSB, and may include other bits, such as at least one of HFI, other timing related information and reserved bits. Another possible way is that the physical layer generates 16 bits, containing the 6bit frame number LSB and partial index, and possibly other bits, such as at least one of HFI, other timing related information, reserved bits. Another possible way is that the physical layer generates 16 bits, containing 8bit frame number LSB and partial index, and possibly other bits, such as at least one of HFI, other timing related information, reserved bits. Another possible way is that the physical layer generates 16 bits, containing the 10 bit frame number LSB and partial index, and possibly other bits, such as at least one of HFI, other timing related information, reserved bits.
More specifically, for example, in combination with the above-mentioned case that the broadcast channel with the index mod M1 taking the same value is QCL, repeated or at least partially the same specific content, if M1 is 2, the physical layer generated bits need to at least include the 6-bit frame number LSB and the 5-bit index MSB, and in this case, a possible way is to generate 16 bits by the physical layer, including the 6-bit frame number LSB and the 5-bit index MSB, and possibly other bits, such as at least one of HFI, other timing related information, and reserved bits. Similarly, the physical layer generated bits may also contain 8-bit or 10-bit frame number and index related bits.
More specifically, for example, in combination with the above case that the broadcast channel with the same index/M2 value is QCL, repeated or at least partially has the same specific content, if M2 is 2, the physical layer generated bits need to at least include 6-bit frame number LSB and 2-bit index LSB, and in this case, a possible way is that the physical layer generates 8 bits, where the 8 bits are 6-bit frame number LSB and 2-bit index LSB respectively; another possible way is that the physical layer generates 16 bits, containing the 6bit frame number LSB and the 2bit index LSB, and possibly other bits, such as at least one of HFI, other timing related information, reserved bits. Similarly, the physical layer generated bits may also contain 8-bit or 10-bit frame number and index related bits.
For example 2, if the broadcast channel TTI is 160ms or the broadcast channel period T is 160ms, and it is assumed that two broadcast channels with a length of 160ms or any index located in different frames in the period are QCL, repeated or at least partially identical in specific content, and the time interval between the frames where these broadcast channels are located is P. Let P be 40 ms. Assuming that the broadcast channel payload is 32 bits, the broadcast channel content generation scheme may be:
the high layer generates 24 bits, and the physical layer generates 8 bits;
alternatively, the upper layer generates 16 bits and the physical layer generates 16 bits.
More specifically, for example, in combination with the above-mentioned case that the broadcast channel with the same index is QCL, repeated or at least partially has the same specific content, the physical layer generated bits need to include at least 4 bits of frame number and partial index related bits, and in this case, a possible way is that the physical layer generates 8 bits, where the 8 bits are respectively 4 bits of frame number LSB and 3 bits of index MSB, and may include other bits, such as at least one of HFI, other timing related information, and reserved bits. Another possible way is that the physical layer generates 16 bits, containing the 4-bit frame number LSB and the 3-bit index MSB, and possibly other bits, such as at least one of HFI, other timing related information, reserved bits. Similarly, the physical layer generated bits may also contain 8-bit or 10-bit frame number and index related bits.
More specifically, for example, in combination with the above-mentioned case that the broadcast channel with the same index mod M1 value is QCL, repeated or at least partially identical in specific content, if M1 is 2, the physical layer generated bits need to include at least a 4-bit frame number and a 5-bit index MSB, and in this case, a possible way is to generate 16 bits by the physical layer, including a 4-bit frame number LSB and a 5-bit index MSB, and possibly other bits, such as at least one of HFI, other timing related information and reserved bits. Similarly, the physical layer generated bits may also contain 8-bit or 10-bit frame number and index related bits.
More specifically, for example, in combination with the above-mentioned case that the broadcast channel with the same index/M2 value is QCL, repeated or at least partially the same specific content, if M2 is 2, the physical layer generated bits need to at least contain 4-bit frame number LSB and 2-bit index LSB, and in this case, a possible way is that the physical layer generates 8 bits, which are 4-bit frame number LSB and 2-bit index LSB respectively; another possible way is that the physical layer generates 16 bits, containing a 4bit frame number LSB and a 2bit index LSB, possibly also containing other bits, e.g. at least one of HFI, other timing related information, reserved bits. Similarly, the physical layer generated bits may also contain 8-bit or 10-bit frame number and index related bits.
For example 3, if the broadcast channel TTI is 160ms or the broadcast channel period T is 160ms, assuming that a TTI of length 160ms or any broadcast channel located in the same frame in the period is QCL, repeated or at least partially identical to a specific content, assuming that the broadcast channel payload is 32 bits, the broadcast channel content generation scheme may be: the 32 bits of broadcast channel content are all generated by the higher layer.
If the broadcast channel TTI is 160ms or the broadcast channel period T is 160ms, assuming that a TTI of length 160ms or any broadcast channel located in different frames within a period is QCL, repeated or at least partly of the specific content is the same, and the time interval between these frames is 40ms, assuming that K is 2:
the bits generated by the physical layer at least need to contain the lowest 3 bits of the frame number, and assuming that the size of the broadcast channel is 32 bits, the generation method may include:
the high layer generates 24 bits, and the physical layer generates 8 bits;

It should be further noted that, in the embodiment of the present invention, when all the first information is generated by the higher layer, the sending end performs channel coding on the content of the broadcast channel (that is, the first information), and then performs scrambling on the first information, and correspondingly, after the receiving end performs channel content reception, it is necessary to perform descrambling on the content of the broadcast channel first, and then perform channel decoding.
In this embodiment of the present invention, when all the first information is generated by the physical layer, the implementation manner of sending includes one of the following:
the first method is that the sending end performs channel coding on the content of the broadcast channel (i.e. the first information), and then scrambles the first information, and correspondingly, the receiving end needs to perform descrambling on the content of the broadcast channel after performing channel content reception, and then performs channel decoding;
the second way, the sending end scrambles the first information before channel coding the content of the broadcast channel (i.e. the first information), then carries out channel coding, correspondingly, the receiving end needs to decode the content of the broadcast channel first after receiving the channel content, and then descrambles the first information;
the third mode is that the first layer scrambling is carried out on the first information, then the channel coding is carried out, and the second layer scrambling is carried out after the channel coding; correspondingly, after receiving the channel content, the receiving end performs the second layer descrambling, then performs the channel decoding, and finally performs the first layer descrambling.
In the embodiment of the present invention, when the first information is generated by the physical layer and the high layer, the transmission is implemented as follows:
first layer scrambling is carried out on partial information generated by a physical layer, then channel coding is carried out on information blocks generated by the physical layer and a high layer, and finally second layer scrambling is carried out on the information after the channel coding; correspondingly, after receiving the channel content, the receiving end performs the second layer descrambling, then performs the channel decoding, and finally performs the first layer descrambling.
It should be further noted that, if the resource location of the broadcast channel does not overlap with the first resource, the sending end may send the first information to the receiving end through the broadcast channel.
If the resource position of the broadcast channel is overlapped with the first resource, the sending end can transmit the broadcast channel on the overlapped resource; or when the transmitting end determines that the transmission resource of the broadcast channel overlaps with the first resource, the broadcast channel is not transmitted on the overlapped resource.
When the transmitting end determines that the transmission resource of the broadcast channel is overlapped with the first resource at the transmitting end, the transmitting end can transmit the first broadcast channel on the resource which is not overlapped and is closest to the overlapped resource after the overlapped resource position when the transmitting end does not transmit the broadcast channel on the overlapped resource;
wherein the first broadcast channel is a broadcast channel that is not transmitted on overlapping resources.
It should be noted that this case refers to delayed transmission to the broadcast channel.
