The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.
The following describes a method, an apparatus, and a communication device for determining a transport block size according to the present disclosure in detail with reference to the accompanying drawings.
The execution subject in this embodiment may be a user equipment side or a base station, and is not limited in this embodiment.
Fig. 1 is a flowchart illustrating a method for determining a size of a transport block according to an embodiment of the present disclosure.
As shown in fig. 1, the method comprises the following steps:
in step 101, the actual number of resources for which logical transport may map REs is determined.
Wherein, Resource Element (RE) with minimum granularity of physical layer
In this embodiment, the logical transmission is opposite to the actual transmission, for example, in a transmission process of a Physical Uplink Shared Channel (PUSCH) based on a retransmission Type b (retransmission Type b), a time slot crossing may occur. For such cases where the transmission spans a slot or where an unavailable symbol is encountered during transmission, Repetition Type B introduces the concept of actual retransmission for the actual transmission. A transmission in Repetition Type B is called a nominal transmission timing, and when the nominal transmission timing meets the situation, the transmission is divided into two actual transmissions. When the time slot is divided, the two divided actual transmissions may belong to the same logical transmission.
As shown in fig. 2, to reduce latency and improve reliability, Rel-16 supports a PUSCH repetition transmission scheme in units of Mini-slots, and allowing PUSCH transmissions to span slots may further reduce latency. In the PUSCH transmission process, the S slot and the U slot respectively include 14 symbols, if a symbol continuously occupied by one transmission is 8, and the starting position is the 12 th symbol of the S slot, when the S slot and the U slot are crossed, the S slot and the U slot are split into two actual transmissions with symbol lengths of 2 and 6, that is, the actual transmissions 1 and 2 in fig. 2 are respectively corresponding, and the actual transmissions 1 and 2 belong to one logical transmission and are denoted as logical transmission 1. In another scenario, within a slot, a transmission occupies 4 consecutive symbols, for example, in an S slot, and the transmission is re-split into two actual transmissions, such as actual transmission 3 and actual transmission 4 in fig. 2, because of the existence of the unavailable symbol, and actual transmission 3 and actual transmission 4 belong to one logical transmission, which is denoted as logical transmission 2.
Furthermore, in this embodiment, the actual number of resources of the logical transmission mappable REs is determined, instead of determining the number of resources 1 corresponding to the actual transmission 1 and the number of resources 2 corresponding to the actual transmission 2, respectively. Furthermore, the corresponding size of the transmission block is determined according to the number of resources 1 and the corresponding size of the transmission block is determined according to the number of resources 2, so that the determined size of the transmission block reduces the code rate, and meanwhile, the combining gain is lower than the coding gain, and the coverage cannot be improved. In this embodiment, the determined actual resource number of the RE is mapped according to the actual transmission 1 and the actual transmission 2 belonging to one logical transmission, so that the actual resource number of the RE corresponding to the two actual transmissions belonging to one logical transmission is increased.
In this embodiment, the number of bits of the intermediate information is determined according to the actual number of resources and the MCS (Modulation and Coding Scheme) level, and the size of the transport block is determined according to the number of bits of the intermediate information. As one implementation mode, the number N of the intermediate information bits is calculated according to the determined actual resource numberinfo. Wherein, the number of intermediate information bits NinfoCalculated according to the following formula:
Ninfo＝NRE×R×Qm×v
wherein R and QmIs the code rate and modulation order determined according to the MCS level. For Type1 uplink scheduling-free transmission, the MCS level is configured by Radio Resource Control (RRC) signaling; otherwise, the indication is dynamically indicated by a Downlink physical Control channel (DCI).v is the number of layers, and for the data channels scheduled by DCI format 0_0 and DCI format 1_0, single-layer transmission is defaulted. And determining the layer number according to the indication of the DCI for the data channels scheduled by the DCI format 0_1 and the DCI format 1_ 1. And for Type1 uplink scheduling-free transmission, determining v according to RRC signaling configuration. N is a radical ofREThe actual number of resources that the RE can be mapped to for logical transmission.
Then, for N againinfoQuantization is performed to determine the final transport block size, where NinfoQuantization is performed to determine the size of the final transport block, which needs to satisfy byte alignment and is an integer multiple of the number of code blocks. N is a radical ofinfoThe quantization also takes into account both scheduling flexibility, measured by the MC for a particular transport block, and overhead.
In the method for determining the size of the transport block according to the embodiment, the actual resource number of the logical transmission mappable RE is determined, the size of the transport block is determined according to the actual resource number of the logical transmission mappable RE, and the size of the transport block is determined based on the logical transmission, that is, the actual transmission across time slots, so that the code rate reduction is avoided.
Fig. 3 is a flowchart of another method for determining a transport block size according to an embodiment of the present disclosure, which illustrates how to determine an actual number of resources of mappable REs across logical transports of an actual transport. As shown in fig. 3, the method comprises the following steps:
The execution subject in this embodiment may be a user equipment side or a base station, and is not limited in this embodiment. In this embodiment, an execution subject is taken as an example of a user equipment, and description is given.
In an implementation manner of this embodiment, a Physical Resource Block (PRB) is a PRB that can be allocated by the network side device for the UE to perform logical transmission.
In this embodiment, the total number of resources of the corresponding RE is determined according to the number of PRBs and the number of time domain symbols allocated to the logical transmission, and then the number of unusable RE resources is deducted from the determined total number of resources.
In this embodiment, the unusable REs include at least one of:
RE occupied by DeModulation Reference Signal (DM-RS) in logically transmitted PRB;
REs occupied by unavailable symbols in logically transmitted PRBs;
and repeatedly transmitting occupied REs in the logically transmitted PRB, wherein the repeated transmission is repeated transmission in two adjacent symbols belonging to different time slots.
Of course, the unavailable RE may also include other parameters; the embodiments of the present disclosure are not limited thereto.
It should be noted that the deducted number of unavailable RE resources is related to the scenario of logical transmission to increase the actual number of resources of the obtained logical transmission mappable REs, and two scenarios are respectively adopted for description below.
In one scenario of this embodiment, the transmission is re-partitioned inside the slot due to the invalid symbols encountered, forming the actual retransmission. As shown in fig. 2, a logical transmission 2, where symbols 4 and 5 are preset unusable symbols, is re-divided into two actual transmissions 3 and 4 when the transmission encounters unusable symbols 4 and 5, where the actual transmissions 3 and 4 belong to one logical transmission 2 and the unusable symbols 4 and 5 are included in the logical transmission 2. The unusable symbols may be symbols reserved for other purposes, for example, dynamic DL symbols or dynamic UL symbols corresponding to the semi-static Flexible. Unusable symbols may be identified by an invalid pattern.
Therefore, in order to improve the accuracy of determining the size of the transport block corresponding to the logical transmission, in this embodiment, the actual number of resources of the logical transmission mappable RE may be determined by the following formula, and then the size of the transport block is accurately determined according to the determined actual number of resources, where the method for determining the size of the transport block may refer to the explanation in the foregoing embodiment, and is not described in detail in this embodiment.
NRE＝12·nPRBNumber of symbols-NDMRS-NInvalidationFormula (1)
Wherein n isPRBThe number of PRBs that can be used for logical transmission allocated to the UE by the network side device is equal to the total number of symbols corresponding to the logical transmission, for example, logical transmission 2 shown in fig. 2, where the number of symbols is 6, and the symbols are carried by DCI or RRC signaling; n is a radical ofDMRSThe resource number occupied by the DM-RS in all the available PRBs is a value determined according to the mapping types of the time domain and the frequency domain of the DMRS; n is a radical ofInvalidationThe number of RE resources corresponding to the unavailable symbol, e.g. as shown in FIG. 2, the number of the unavailable symbols is 4 and 5, i.e. the number of the unavailable symbols is 2, the number of the corresponding RE resources is NInvalidation＝12*nPRB*2. In the above formula (1) in the embodiment of the present disclosure, only the parameter N may be includedDMRSAnd parameter NInvalidationEither one of the two parameters and the other parameter, or both of the two parameters and the other parameter; the disclosed embodiments are not limited thereto.
It should be noted that the scenario shown in fig. 2 is only an example, and does not constitute a limitation to the present disclosure.
In this embodiment, after a transmission in the same timeslot encounters one or a plurality of consecutive unavailable symbols, the transmission may be split into two actual transmissions again, in order to improve the accuracy of determining a transmission block, the logical transmissions corresponding to the two actual transmissions are determined, the total number of RE resources is determined according to the PRB allocated for the logical transmission, and then the number of RE resources occupied by the DM-RS and the number of RE resources occupied by the invalid symbols are deducted from the total number of resources to determine the total number of RE resources required for the logical transmission, and then the size of the transmission block is determined according to the number of RE resources, thereby improving the accuracy of determining the size of the transmission block and avoiding a reduction in code rate.
In another scenario of this embodiment, where a transmission opportunity occurs across slot boundaries, the transmission is re-split, corresponding to two actual transmissions.
In this embodiment, there is a problem of phase distortion when transmitting across time slots, and in order to avoid phase distortion, as one implementation, repeated transmission is set in two adjacent symbols belonging to different time slots. The repeated transmission is all or part of each adjacent symbol, that is, partially or completely the same content is mapped in each adjacent symbol.
In an implementation manner of this embodiment, the same content or all the same content may be mapped in each adjacent symbol by performing time-frequency domain transformation on the repeated transmission and the remaining partial transmission in the same adjacent symbol, respectively.
In this embodiment, the repeated transmission includes repeated data or repeated DM-RS.
Therefore, because the adjacent symbols across the time slot are mapped with the same or all the same content, when determining the actual resource number of two actually-transmitted mappable REs belonging to the same logic transmission across the time slot, the resource number of the REs corresponding to the repeated transmission needs to be removed, so as to improve the accuracy of the actual resource number corresponding to the logic transmission.
In an implementation manner of this embodiment, the total number of REs determined by the logical transmission further includes an RE symbol corresponding to the invalid symbol, and the actual number of resources of the mapped REs in the logical transmission can be determined by the following formula.
NRE＝12·nPRBNumber of symbols-NDMRS-NRepetition of-NInvalidation； (2)
Wherein n isPRBThe number of PRBs that can be used for logical transmission allocated to the UE by the network side device is equal to the total number of symbols corresponding to the logical transmission, for example, the number of symbols is 8 for the logical transmission shown in fig. 2, and the symbols are carried by DCI or RRC signaling; n is a radical ofDMRSThe resource number occupied by the DM-RS in all the available PRBs is a value determined according to the mapping types of the time domain and the frequency domain of the DMRS; n is a radical ofRepetition ofThe number of RE resources occupied for data repeat transmission; n is a radical ofInvalidationThe number of RE resources corresponding to the unavailable symbol.
In the above formula (2) in the embodiment of the present disclosure, only the parameter N may be includedDMRS、NRepetition ofAnd parameter NInvalidationOr any one of these three parameters and other parameters; the disclosed embodiments are not limited thereto.
In an implementation manner of this embodiment, the total number of REs determined by the logical transmission does not include an RE symbol corresponding to an invalid symbol, and the actual number of resources of the mapped REs in the logical transmission can be determined by the following formula.
NRE＝12·nPRBNumber of symbols-NDMRS-NRepetition ofFormula (3)
In this embodiment, when performing cross-slot transmission, the accuracy of determining the actual number of resources of the logical transmission mappable RE is improved by deducting the number of RE resources occupied by the DM-RS and further deducting the number of resources corresponding to the existence of the repeated transmission and/or invalid symbols.
In the above formula (3) in the embodiment of the present disclosure, only the parameter N may be includedDMRSAnd NRepetition ofAny one of the parameters, or including any one of the two parameters and other parameters; the disclosed embodiments are not limited thereto.
Specifically, in this step, reference may be made to the method for determining the size of the transport block in the foregoing embodiment, and the principle is the same, which is not described herein again.
In the method for determining the size of the transmission block in this embodiment, the total number of RE resources is determined according to the PRB allocated for logical transmission, and then the number of unavailable RE resources is deducted from the total number of resources, so that the accuracy of determining the actual number of resources is improved, and then the size of the transmission block is determined according to the number of RE resources, so that the accuracy of determining the size of the transmission block is improved, and the reduction of the code rate is avoided.
