The specific time length of each slot is determined by a set of parameters, which may include, for example, subcarrier spacing (SCS). For example, when SCS is 15kHz, one slot is 1ms long; with a subcarrier spacing of 30kHz, one slot is 0.5ms long.
The NR supports a time slot for uplink transmission, and the time slot is marked as U slot; NR supports one time slot for downlink transmission, and the time slot is marked as D slot; NR supports the configuration of one slot with both uplink and downlink, which is denoted as S slot. Typical Time Division Duplex (TDD) system time slot configuration formats include DDDSU, DDDSUDDSUU, dddddddddduu, and the like. It is understood that one timeslot may include downlink symbols (downlink symbols), uplink symbols (uplink symbols), and flexible symbols (flexible symbols), where the downlink symbols cannot be used for uplink transmission; the uplink symbols cannot be used for downlink transmission; and flexible symbols may be used for both downlink and uplink transmissions.
In the Long Term Evolution (LTE) standard, an uplink slot is composed of discrete Fourier transform-spread-orthogonal frequency-division multiplexing (DFT-S-OFDM) symbols.
2. Frequency domain structure
NR defines a Resource Element (RE) as a subcarrier on an OFDM symbol, and the RE is the smallest physical element in the NR standard. The 12 subcarriers consecutive in the frequency domain are referred to as a Resource Block (RB). Although one RB fixedly includes 12 subcarriers, actual bandwidths occupied by different RBs in the frequency domain are not necessarily the same due to different subcarrier spacings.
3. Uplink channel and signal
The uplink channel in NR includes: a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), and a Physical Random Access Channel (PRACH).
The uplink signal in NR includes: a Sounding Reference Signal (SRS), a demodulation reference signal (DMRS), and a phase-tracking reference signal (PTRS). The uplink DMRS is transmitted along with the PUCCH and the PUSCH, and the time-frequency resources occupy a part of the PUCCH or the PUSCH. The uplink PTRS is transmitted along with the PUSCH, and the time-frequency resource occupies a part of the PUSCH.
4. Three PUSCH transmissions
PUSCH transmission in NR is divided into three types: PUSCH transmission based on dynamic scheduling, PUSCH transmission of Configuration Grant (CG) type1 (type), and PUSCH transmission of CG type 2.
The PUSCH transmission based on dynamic scheduling, i.e., each PUSCH transmission, is scheduled by using Downlink Control Information (DCI) indicated by a physical layer. In such transmission, the terminal device performs PUSCH transmission once upon receiving uplink scheduling once.
Among them, the PUSCH transmission of CG type, i.e. the semi-persistent scheduled PUSCH transmission, receives a higher layer configuration (higher layer parameter configgradntconfig including rrc-configurable uplink grant), does not receive a physical layer indication DCI, and is called configured uplink grant in the protocol. In the transmission, a high layer configures some semi-persistent resources, and if there is uplink data to be sent, the terminal equipment can send the PUSCH by using the resources; and if no uplink data needs to be sent, not sending the data.
In the PUSCH transmission of CG Type2, a higher layer configuration (higher layer parameter config that does not include rrc-configurable uplink grant) is received first, and then the physical layer indicates DCI activation or deactivation, which is referred to as configured uplink grant based on L1 signaling in the protocol. In such transmission, the higher layer configures some semi-persistent resources, which are then activated/deactivated by physical layer signaling: the behavior is similar to configuring the Type1 PUSCH transmission when activated; without activation, these resources cannot be used.
General procedure for PUSCH processing
In NR, an encoding process of a PUSCH Transport Block (TB) in data (uplink shared channel) transmission of PUSCH can be seen in fig. 1. Fig. 1 is a schematic diagram of an encoding process, and referring to fig. 1, it can be seen that, for one TB, a terminal device may sequentially perform Cyclic Redundancy Check (CRC) attachment of a transport block, code Block (CB) segmentation, code block CRC attachment, channel coding, rate matching, code block concatenation, scrambling (scrambling), modulation (modulation), precoding, symbol mapping, and the like.
If the bit sequence of TB is a 0 ，a 1 ，a 2 ，a 3 ，…，a A-1 And a is the payload size. The performing, by the terminal device, transport block CRC attachment on the TB may include: the terminal equipment determines a generating polynomial of CRC and a check bit number L according to the effective load size A of the TB; the terminal equipment generates a check bit sequence p according to the bit sequence of the TB and the generating polynomial of the CRC 0 ，p 1 ，p 2 ，p 3 ，…，p L-1 And will check the bit sequence p 0 ，p 1 ，p 2 ，p 3 ，…，p L-1 Attaching to the TB bit sequence to obtain a CRC-attached bit sequence b 0 ，b 1 ，b 2 ，b 3 ，...，b B-1 . Wherein B = a + L. Then, if B is larger than the maximum code block size K cb The terminal equipment divides the code block of the bit sequence of the TB to obtain C code blocks, and the bit stream of each code block in the C code blocks is C r0 ，c r1 ，c r2 ，c r3 ，…，c r(K′-L-1) R is an integer of 0 or more and less than C, r is a code block number, and K' is K r Or K, K r K is the number of bits of the r-th code block. Then, the terminal device determines a CRC check bit sequence for each code block from the bit stream for each code block
And the CRC check bit sequence of each code block is->
Attached to the corresponding codeblocks, resulting in an attached bit sequence ∑ of each codeblock>
Where the number of parity bits L =24 per code block. Next, in NR, for the data channel, the terminal device may perform LDPC channel coding on each code block using a Low Density Parity Check (LDPC) code, where an input of the channel coding may be c, for example 0 ，c 1 c 2 ，c 3 …，c K-1 The output of the channel coding may be d 0 ，d 1 ，d 2 ，d 3 ...，d N-1 And N is the length of the sequence after the channel coding of the channel coding input. Of course, the terminal device may also perform rate matching on each code block, where the rate matching may include bit selection (bit selection) and bit interleaving (bit interleaving), which is not described herein in detail. Wherein the input of the rate matching can be d 0 ，d 1 ，d 2 ，d 3 ，...，d N-1 The output of the rate matching may be f 0 ，f 1 ，f 2 ，f 3 ，…，f E-1 And E is the length of the sequence subjected to rate matching by the rate matching input. Then, the terminal device may further match the bit f of the rate-matched C code blocks rk Sequentially cascading to obtain a bit sequence g t . Wherein k is greater than or equal to 0 and less than or equal to E r-1 An integer of (E) r Is the bit number of the r code block after rate matching, t is an integer greater than or equal to 0 and less than or equal to G-1, G is a bit sequence G t Length of (d).
In addition, the terminal equipment can also process the bit sequence g t And (4) scrambling. E.g. for a single codeword q =0, the bit sequence before scrambling is
The scrambled bit sequence is->
Is the number of bits corresponding to one constellation point. It will be appreciated that scrambling is analogous to £ being @>
For the scrambled bit sequence, b (q) (i) For bit sequences before scrambling, c (q) (i) Is a scrambling sequence, i is greater than or equal to 0 and less than or equal to->
Is an integer of (1). Then, the terminal device can also perform constellation modulation on the scrambled bit sequence to obtain a complex modulation symbol sequence->
Then, the terminal device may multiply the complex modulation symbol sequence and the precoding matrix to obtain a precoded complex modulation symbol sequence
ap (antenna port) is the number of antenna ports. Finally, for each antenna port, the terminal device may map the precoded complex modulation symbol sequence to a time-frequency resource. The reserved resources (such as DMRS, PTRS, etc.) preset by the protocol may be skipped during mapping, and the mapping may be performed according to the sequence of the frequency domain first and the time domain later, for example, starting from the lowest-sequence subcarrier of the first OFDM symbol, mapping in ascending order according to the subcarrier number, after mapping all subcarriers of the first OFDM symbol, mapping from the lowest-sequence subcarrier of the second OFDM symbol. And so on until the allocated time-frequency resources are mapped.
Two repetition types of PUSCH (repetition Type)
The PUSCH repetition types in NR are divided into two types: the PUSCH repetition Type A is adopted in the Rel-15 version, and the PUSCH repetition Type B is newly introduced in the Rel-16 version.
The PUSCH repetition Type A is repeated for K times by taking a time slot as a unit, and a starting symbol S is a starting position of a relative time slot; l is the number of consecutive symbols from S allocated to PUSCH; s and L are determined by start and length indication SLIV. When K > 1, the same symbol allocation is applied over K consecutive slots. The design of the effective 5 and L combination is specified in the protocol so that PUSCH repetition type a does not cross slot boundaries. And if a symbol in a certain group of allocated symbols cannot be used for transmitting the PUSCH repetition, canceling the PUSCH repetition transmission.
For example, referring to fig. 2, fig. 2 is a schematic diagram of a mapping pattern of a PUSCH repetition Type a. It is understood that, in fig. 2, S =0, l =10, k =4. In each slot, L (L = 10) consecutive symbols are used for transmitting PUSCH starting from the starting symbol S (S = 0). For example, in slot 1, 10 consecutive symbols starting from the 0 th symbol from left to right are used for transmitting PUSCH, i.e., rep # 1; in slot 2, starting from the 0 th symbol from the left to the right, 10 consecutive symbols are used for transmitting PUSCH, i.e. Rep # 2; in slot 3, 10 consecutive symbols starting from the 0 th symbol from left to right are used for transmitting PUSCH, i.e., rep # 3; in slot 4, 10 consecutive symbols starting from the 0 th symbol from left to right are used for transmitting PUSCH, i.e., rep # 4. Therefore, it can be seen that the PUSCH is repeated 4 times in units of slots, i.e., rep # 1 to Rep # 4.
The PUSCH repetition Type B is repeated for K times by taking the length L indicated by the network side as a unit, and the starting symbol S is the starting position of a relative time slot; l is the number of consecutive symbols from S allocated to PUSCH. PUSCH repetition type B is more flexible than PUSCH repetition type a, and there may be a case where a repetition crosses a slot boundary or a repetition includes invalid symbols(s), and at this time, the repetition may be split. In the protocol, the repetition before splitting is called nominal repetition (nominal repetition), the repetition after splitting is called actual repetition (actual repetition), and the repetition number K indicated by the network side refers to the total number of nominal repetition.
For example, referring to fig. 3, fig. 3 is a schematic diagram of a mapping pattern of PUSCH repetition Type B. It can be understood that, in fig. 3, S =11, l =7, k =4. As can be seen from fig. 3, the 4 nominal reptitions are split into 6 actual reptitions due to the existence of the slot boundary.
When the repetition of PUSCH repetition type B encounters invalid symbols, such as downlink symbols, the nominal repetition will first strip these invalid symbols. If the number of potential valid symbols in a nominal repetition is greater than 0, then the nominal repetition will include one or more actual repetitions, each of which is transmitted with consecutive valid symbols (a single-symbol actual repetition is ignored unless L = 1).
Exemplarily, referring to fig. 4, fig. 4 is a schematic diagram of a mapping pattern of another PUSCH repetition Type B. It can be understood that, in fig. 4, S =0, l =7, k =2. In fig. 4, 2 times nominal repetition is split into 3 times actual repetition due to the existence of invalid symbols (i.e., downlink symbols), and the number of valid symbols for PUSCH transmission is also reduced.
Limitation of PUSCH Transmission data Rate
J =0,1,2, \ 8230;, J-1, if slot s, of the jth serving cell in a cell group j At any time point above, the following condition is not satisfied, and the terminal device does not need to time slot s in the jth serving cell j Medium processing PUSCH transmission:
Wherein the content of the first and second substances,
is the duration of a time slot, mu (j) is the time slot s in the jth cell j The sub-carrier spacing configuration of the PUSCH in (2). The relationship between the subcarrier spacing configuration μ and the subcarrier spacing Δ f in NR is shown in the following table:
| μ | Δf＝2 μ ×15[kHz] | cyclic Prefix (CP) |
| 0 | 15 | |
| 1 | 30 | |
| 2 | 60 | Normal，Extended |
| 3 | 120 | |
| 4 | 240 | Normal |
Wherein, for the mth TB, there are
A is the number of bits of the transport block, such as the payload size in 5 above. C is the total code block number of the transport block, such as the total code block number in the above 5. C' is the scheduled number of code blocks for the transport block. Specifically, if there is no Code Block Group Transmission Information (CBGTI) field in the DCI scheduling the TB, C' = C; if there is a CBGTI field in the DCI scheduling the TB, C' is the number of scheduled code blocks of the transport block.
The DataRate is the maximum data rate in megabits per second (Mbps) after summing all carriers. The calculation formula is in the form of summing up a plurality of Component Carriers (CCs), and the parameters are all parameters that are given by a higher layer and that the terminal device can support the maximum, thereby calculating the maximum data rate supported by the terminal device.
Illustratively, referring to fig. 5, fig. 5 is a diagram of data rates of TBs transmitted on different carriers. As shown in fig. 5, there are 3 serving cells, the subcarrier intervals corresponding to 3 CCs are 60kHz, 30kHz, and 15khz, respectively, and tb0, TB1, and TB2 are transmitted on CC0, CC1, and CC2, respectively. At time 1, the data rates of the TBs transmitted on the different carriers satisfy the following equation:
wherein, TB0, TB1 and TB2 respectively represent the number of bits transmitted by each TB.
In addition to the above limitation of the data rate of the terminal device in a whole cell group, there is also a limitation of the data rate of the terminal device for the jth serving cell. The method specifically comprises any one of the following conditions:
it can be appreciated that under the limitation of any one of the above conditions, the terminal device does not need to process the transmission of the PUSCH when the following conditions are not satisfied:
wherein, L is the number of symbols allocated to PUSCH; m is the TB number in the PUSCH; />
Is the symbol number in a time slot, mu is the subcarrier interval configuration of PUSCH; v j，m Reference may be made to the above description, which is not repeated herein. DataRateCC is the maximum data rate for one carrier in Mbps.
8. Transport block processing for multi-slot PUSCH
In the NR R-15/R-16 protocol version, in most cases, one transport block is transmitted on only one slot (unless for PUSCH repetition Type B, the same transport block is transmitted on at most two slots when the nominal repetition is divided into actual repetitions by slot boundaries). That is, in the current NR protocol, the base station does not actively schedule one transport block to be transmitted on multiple slots.
In the discussion of R-17 Coverage Enhancement (CE), a multi-slot PUSCH transport block processing (TBoMS) Work Item Description (WID) is approved, and TBoMS refers to a base station side scheduling a TB to correspond to a PUSCH on multiple slots for transmission.
The advantages of TBoMS can be summarized as follows: in a scene with limited uplink coverage, by aggregating smaller packets (packets) in a plurality of time slots, the TBoMS can increase channel coding gain; by transmitting a single TB on a plurality of time slots, only one TB cyclic redundancy check code is attached, and the bit number occupied by the TB CRC is reduced; the single TB of the TBoMS is elongated in the time domain, so that the number of RBs occupied by the frequency domain is reduced, and the power spectral density is improved.
Time domain resource allocation for TBoMS
In the recent discussion of RAN1#105-e conference, the Time Domain Resource Allocation (TDRA) scheme of TBoMS is determined as the TDRA scheme of PUSCH repetition Type a, and this conclusion is written into the protocol. In addition, for the unpaired spectrum (i.e. TDD) scenario, the resource used for transmitting TBoMS is allocated in S slot, and whether the TDRA of S slot needs to be optimized or not is still to be discussed.
Transport block size for TBoMS
In the discussion of RAN1#105-e conference, the Transport Block Size (TBS) of TBoMS is determined by: the number of REs is first determined based on the first L symbols of the TBoMS transmission allocation, and then multiplied by K ≧ 1. Here, L is L in SLIV of TDRA of PUSCH, and represents the number of symbols; the definition of K is still to be discussed.
In addition, in the RAN1#104-e conference discussion, the maximum TBS of TBoMS is written unchanged into the protocol. That is, although a single TB of a TBoMS is spread to be transmitted over multiple slots, the maximum size of the single TB of the TBoMS still coincides with the maximum size of a TB transmitted on one slot in R-15/R-16.
Transmission timing of TBoMS
In the NR R-15/R-16 protocol version, the Transmission Occasion (TO) of the PUSCH is specified for a non-repeated PUSCH, and a PUSCH repetition Type a, the TO being one repetition of the PUSCH in one slot. TO is a basic unit of a power control (power control) and Redundancy Version (RV) cycle (cycling).
In the conference discussion of RAN1#104-bis-e, a working assumption (working assumption) is proposed to define the transmission timing for TBoMS, i.e., TOT (transmission opportunity for TBoMS). In the RAN1#105-e conference discussion, the TOT is determined to be made up of at least one or more consecutive physical time slots for uplink transmission. Meanwhile, the design level of the TOT related to signal generation, such as the relationship between Rate Matching (RM), RV cycling, power control, collision handling (collision handling), etc., still needs to be discussed.
Rate matching with RV for TBoMS
In the discussion of the RAN1#105-e conference, the following three rate matching modes are determined, and only one RM mode is finally selected in consideration of screening in the next conference, namely, the RAN1#106-e conference:
(1) Rate matching is performed slot by slot;
(2) Rate matching is performed TOT-by-TOT, i.e., RMs are performed consecutively on all timeslots allocated by one TOT;
(3) Rate matching is performed continuously on all slots/all TOTs allocated by TBoMS.
In the NR protocol flow, the determination of redundancy version belongs to the part of bit selection. For RV cycling of TBoMS, a single RV may be used or multiple RVs may be used on the entire TBoMS, and still be discussed in a subsequent conference.
At present, when calculating a data rate corresponding to a physical uplink shared channel, a scenario that a transport block is not transmitted across a time slot is targeted. However, if the data rate is calculated for a scenario where one TB is transmitted across a plurality of slots (i.e., for TBoMS to be introduced by R-17), and still according to a scenario where one TB is not transmitted across slots, there is a problem that the calculated data rate error is large. In other words, if a TB is transmitted across multiple slots, the data rate calculation formula referred to in 7 above (numerator is still the number of bits that the TB is scheduled to transmit, and denominator is the duration of one slot (multi-CC formula) or the duration of L symbols in one slot (single-CC formula)) is still used, resulting in a calculated data rate much greater than the data rate actually transmitted by TBoMS, which also limits the TBs transmitted by TBoMS or limits the scheduling of TBoMS. In addition, the data rate referred to in the above 7Formula for calculation
The TBSs on a plurality of serving cells are summed, the data rate calculated for the TBoMS is greater than the true value, and the data rate for PUSCH transmission on other CCs is also limited to be less than the maximum data rate that can be supported by the terminal device, thereby limiting the scheduling of TBs on other CCs or limiting the TBSs of other TBs. Therefore, how to accurately determine the data rate becomes an urgent technical problem to be solved in the current stage for a scenario where one TB is transmitted across multiple timeslots.
Based on this, the present application provides a data rate determining method to solve the above technical problem, and the following detailed description is provided for embodiments of the present application.
