The present disclosure relates to the field of communication, in particular to a transport block (TB) scheduling method and device, a storage medium and an electronic device.
Compared with the condition of using one physical downlink control channel (PDCCH for short) for scheduling one transport block (TB for short), using one PDCCH for multi-TB scheduling may reduce the control signaling overhead and improve the transmission efficiency. During multi-TB scheduling, a corresponding process index, new transmission, retransmission and non-transmission indicators need to be embodied in the design of downlink control information (DCI for short). At the same time, during the sub-package of the upper layer, multi-TB scheduling may result in different transport block sizes (TBS) due to limited transmission resources and uncertain packet sizes.

The embodiment of the present disclosure provides a design completing the DCI with relatively low overhead when one PDCCH schedules multiple TBs with possibly different sizes, which improves transmission efficiency. When the TBS is different, resource scheduling information of different TBs needs to be indicated. When the multiple TBs are scheduled, overlarge overhead is directly and separately indicated, and through a method of classifying the multiple TBs, small-range offset on each type or direct TBS binding on the multiple types may guarantee that the signaling overhead is reduced as much as possible under the condition of scheduling multiple types of different TBs, which includes:
It is set that ISF2=ISF−β, that is, a resource allocation value of indicator 2. Transverse left-right offset is possible without constraints, and principles indicated during offset include:
The methods are mainly as follows:
The transverse position offset refers to an offset of RU index or an offset allocated by RU. The longitudinal position offset refers to an offset to ITBS. In the case that indicator 1 represents a retransmitted TB signaling indicator and indicator 2 is a newly transmitted signaling indicator, the following table is exemplified:
The indicator needs 3 bits, and single-direction offset may be carried out transversely and longitudinally. Indicator 1 may also represent a newly transmitted TB indicator, and then an offset direction of indicator 2 is opposite the direction described above.
Determined forms mainly include coefficients offset values.
The β and α values are optional. Indicator 2 in the table represents that a code rate is greater than or equal to a code rate of indicator 1, and the number of RU is greater than or equal to the number of indicated RU.
1. Classification of the multiple TBs may be indicated with 1 bit-2 bits when 4-TB scheduling is supported. There are mainly three solutions for classification as follows:
Solution 1-1+Solution 1-3 may be selected when 1 bit is used. When the overhead uses 2 bits, the three solutions may all be indicated.
2. Classification of the multiple TBs may be indicated with 1-3 bits when 8-TB scheduling is supported. There are mainly five solutions for classification as follows:
Averaging and non-classification solutions may be selected when 1 bit is used. Other solutions are added on the basis of the averaging solution and the non-classification solution when 2 bits or more are used, making the difference between the numbers of the two types of TBs small as much as possible. It is agreed that the previous type of TBs is indicated by indicator 1, and the second type of TBs is indicated by indicator 2.
Embodiments of the present disclosure are described in detail below by way of specific examples.
The embodiment is mainly used for completing DCI content design under low overhead in different scenes of TBS during multi-TB scheduling enhancement. It mainly elaborates a method that assuming that the channel conditions are identical, the MCS fields ITBS in the DCI are identical and the sampling signaling performs direct indicator in a scene of two newly transmitted or retransmitted TBs, 2-TB scheduling is achieved by using one DCI and a method for multi-TB scheduling is provided.
Situations where sizes of the multiple TBs are different may also occur during multi-TB scheduling. The embodiment mainly describes an indicator method of two newly transmitted or retransmitted TBs or an indicator method of two types of newly transmitted or retransmitted TBs (each type of newly transmitted TBS is identical, and the DCI configuration is consistent). Obviously, the DCI configuration directly indicating 2 TBs is too high in overhead, and some information may be reused. When 2 TBs are indicated to be transmitted by one DCI, the channel conditions may be considered to be identical, the modulation encoding modes are consistent, and ITBS may be kept identical and reused. The scheduling method for directly indicating with signaling is given as follows:
When the offset direction is not fixed, there are examples as follows:
The number of the states is four, and 2 bits are needed to a maximum degree for indicator.
When the offset direction is unidirectional there are examples as follows:
When 2-bit overhead is used:
Different value ranges correspond to different offset interval values; and in an actual high-layer subpackage rule, when the difference between TBS is large, TBS is made to be equal in a padding mode, or TBS is directly consistent or almost identical during subpackage. Therefore, in the case that the method is improved, the indicator may be achieved only with 2 bits or 1 bit. There is method 3 as follows (Imcs, NRU)
Assuming that the TB in indicator 1 is larger at this time, and the TB in indicator 2 is smaller, ITBS is identical, and ISF is offset unidirectionally, that is, ISF is reduced. An offset mode is rounded up (or down) on the basis of ISF of indicator 1 multiplied by the offset, from actual conditions, when the offset is large, the coefficient may be ½ or ⅓ or other values.
In this embodiment, three methods for describing resource allocation and modulation encoding indicator during 2-TB new transmission are given. While multi-TB scheduling is achieved, the indicator method is simplified by using the sub-package rule, and the resource transmission efficiency is improved.
The embodiment is mainly used for completing DCI content design under low overhead in different scenes of TBS during multi-TB scheduling enhancement. It mainly elaborates a method that the signaling performs direct indicator in a scene of one newly transmitted and one retransmitted TBs, 2-TB scheduling is achieved by using one DCI and a method for multi-TB scheduling is provided.
During multi-TB scheduling, a scene of hybrid transmission of a newly transmitted TB and a retransmitted TB, which is set as TB1 and TB2, may occur, and retransmitted TB, that is, TB2 and the corresponding newly transmitted TB, that is, TB1 may or may not be identical in size. The target BLER of the TB2 and the target BLER of the TB1 are inconsistent when the TB2 and the TB1 are identical or different. Two methods are proposed here to address this situation, and a basic solution comparison is as follows:
The principle of the signaling indication method is as follows:
The methods are mainly as follows:
The transverse position offset refers to an offset of RU index or an offset allocated by RU. The longitudinal position offset refers to an offset to ITBS. In the case that indicator 1 represents a retransmitted TB signaling indicator and indicator 2 is a newly transmitted signaling indicator, the following table is exemplified:
The indicator 2 is (ITBS+α, ISF+β), wherein α and β may be valued as the following table:
or:
The indicator needs 3 bits, and single-direction offset may be carried out transversely and longitudinally. Indicator 1 may also represent a newly transmitted TB indicator, and then an offset direction of indicator 2 is opposite the direction described above.
In method 1, indicator 2 may be directly indicated by directly using signaling with a limiting condition that the resource assignment field needs to be kept identical, and 4 bits are needed. Method 2 is to perform search indicator on the indicator 2 on the basis of retransmitted indicator 1. Compared with method 1, the method has the advantages that the resource assignment field may be changed with a limiting condition that search may only be in a limited range. The larger the needed resource overhead is, the more accurate the result is.
In this embodiment, two methods for describing how to indicate DCI resource allocation and modulation encoding during multi-TB transmission of new transmission and retransmission are given. The signaling overhead is effectively saved through different limiting modes and a DCI scheduling solution during hybrid new transmission and retransmission under different TBS is achieved.
The embodiment is mainly used for completing DCI content design under low overhead in different scenes of TBS during multi-TB scheduling enhancement. It mainly elaborates a method using an implicit indicator in a scene of two newly transmitted or two retransmitted TBs, 2-TB scheduling is achieved by using one DCI and a method for multi-TB scheduling is provided.
During 2-TB scheduling, the implicit indicator method has the advantage of not needing extra overhead, and main principles of which include:
Determined forms mainly include coefficients offset values.
Corresponding to the condition of embodiment 1, assuming that the channel conditions may be considered to be identical, the modulation encoding modes are consistent, and ITBS are kept identical by default, which is mainly used for scenes where the two TBs are both newly transmitted or retransmitted. The resource assignment field needs to be designed, and according to main principles of the implicit indicator, the method mainly includes:
The implicit indicator method has large limitation on the value of indicator 2 which may only correspond to indicator 1 one to one. But no extra overhead is need. Meanwhile, the 3 value is optional according to the content in indicator 1.
The embodiment is mainly used for completing DCI content design under low overhead in different scenes of TBS during multi-TB scheduling enhancement. It mainly elaborates a method using an implicit indicator in a scene of one newly transmitted and one retransmitted TBs, 2-TB scheduling is achieved by using one DCI and a method for multi-TB scheduling is provided.
During 2-TB scheduling, under the scene of hybrid new transmission and retransmission, the target BLER may not be consistent, ITBS may be different, and RU may also be different. A principle of the implicit indicator method is consistent with embodiment 3, and assuming that indicator 2 has a fixed magnitude relationship with indicator 1 in the resource allocation amount and the modulation encoding amount, the indicator method is as follows:
The values of β and α are optional. Indicator 2 in the table of method 1 represents that a code rate is greater than or equal to a code rate of indicator 1, and the number of RU is greater than or equal to the number of indicated RU.
The β and α values are optional. Indicator 2 in the table of method 2 represents that a code rate is greater than or equal to a code rate of indicator 1, and the number of RU is greater than or equal to the number of indicated RU.
The example is mainly used for completing DCI content design under low overhead in different scenes of TBS during multi-TB scheduling enhancement. It mainly elaborates a method for achieving multi-TB classification and scheduling by using one DCI in a scene of multiple TBs.
During multi-TB scheduling, a situation may occur in which the multiple TBs all need to be retransmitted, while some TBs need to be newly transmitted, resulting in inconsistencies of multiple TBS. The size of the retransmitted TB may be different from that of the originally transmitted TB, and each newly transmitted TB may also be different. In the case that the multiple TBS with different sizes is transmitted in a mixed manner, great signaling overhead may be caused. The TBs are classified according to the TBS on the basis of 2-TB transmission. The TBs of the same type are consistent in TBS size and reuse the same signaling indicator. Different types of TBs need to be indicated differently. If the types of TB are relatively large, not only the overhead of how to indicate classification is high, but also the overhead of the modulation encoding and the voluntary assignment field of each type are higher. It is limited that only two types of TBs are transmitted in one DCI. The solution for DCI design is:
The method of class-based offset is consistent with the 2-TB transmission indicator method. The TB classification and indicator methods are mainly discussed below. TBs are classified into two types at most, and two transmission solution exist, namely, transmission of two types of TBs and transmission of only one type of TBs. The situations in which the two occur are discussed separately.
Transmission of one type of TBs: when the multiple TBs is transmitted, the sizes of all the TBs transmitted by the DCI content are consistent at the moment, and no extra indicator is needed. At this time, the multiple TBs may be newly transmitted, or all TBs may be retransmitted, and there is a small possibility of hybrid new transmission and retransmission.
Transmission of two types of TBs: when the multiple TBs is transmitted, one DCI content needs to represent two pieces of different TBS information at the moment. At the moment, new transmission and retransmission may be carried out together, and there is a small possibility of all new transmission or all retransmission.
When multiple TBs are scheduled, how many of TBs per type need to be known by a user in order to facilitate decoding.
1). Classification of the multiple TBs may be indicated with 1 bit-2 bits when 4-TB scheduling is supported. There are mainly three solutions for classification as follows:
2). Classification of the multiple TBs may be indicated with 1-3 bits when 8-TB scheduling is supported. There are mainly five solutions for classification as follows:
3) 1 to N/2+1 solutions may be used for describing the classification of the N (N is an even number) TBs when N-TB scheduling is supported, a needed overhead range is 1 to and the solutions are mainly as follows:
Averaging and non-classification solutions may be selected when 1 bit is used. Other solutions are added on the basis of the averaging solution and the non-classification solution when 2 bits or more are used, making the difference between the numbers of the two types of TBs small as much as possible. It is agreed that the previous type of TBs is indicated by indicator 1, and the second type of TBs is indicated by indicator 2.
The above classification solutions must match multi-TB transmission, for example, when 8-TB scheduling supports mixed transmission and the 3+5 solution is adopted, the first three are in one type, and the last five are in one type. When the second DCI performs transmission, 12 processes are retransmitted, the last five processes may be retransmitted or newly transmitted, and all of these states must be supported during mixed transmission. During multi-TB scheduling, the indicator 1 is not guaranteed to be a retransmission indicator.
In this embodiment, two methods for describing classifying the multiple TBs during multi-TB scheduling are given. By adding the limiting conditions, the TBs are classified into two types, specific allocation solutions are elaborated in detail, main solutions are expressed, and DCI overhead thereof is reduced. The DCI indicator during multi-TB scheduling is achieved.
The embodiment is mainly used for completing DCI content design under low overhead in different scenes of TBS during multi-TB scheduling enhancement. It mainly elaborates an indicator method for the multiple TBs in the same DCI during common transmission. The sizes of the multiple TB may differ from one another.
Assuming that N TBs need to be scheduled in the DCI, the N TBs are classified into M types, M<=N, and each type of TBs is identical in size. Compared with the multi-TB scheduling with identical TBS, the newly added content of the DCI is the classification overhead of the TB and the extra indicator overhead when the TBS is different. The indicator mode is similar to Example 3 and is TB classification+class-based offset. To reduce overhead, more limitations on TB classification and class-based offset need to be made.
1) Classification Method
It may only be classified into two types by using 1 bit, which is identical to Example 3. So the classification overhead is a minimum of 2 bits in this embodiment, based on the minimum overhead of 2, the classification method is as follows:
In this embodiment, a classification method and a DCI indicator method are mainly discussed when N>=8. At the moment, the TBs are classified into M types, and one TB is allocated one process at least in each type.
When N=8, M=1, 2, 4, 8, and when there is one type, all TBS are consistent. When M=8, each TB size is different. When M=2, the classification method is consistent with Example 3, and when M=4, one type of TBs contains 2 TBs, corresponding to the process numbers in order. All states of the classification indicator are as shown in the following table:
When M=4, there are other classification methods, for example, 3+3+1+1 represent three TBs of each of the first type of TBs and the second type of TBs and one TB of each of the third type of TBs and the fourth type of TBs. When M=4, all the solution are as follows: 5+1+1+1; 4+2+1+1; 3+3+1+1; 3+2+2+1; 2+2+2+2; and there are 5 solutions in total, so if all solution need to be represented, 1 bit extra overhead is needed. From the aspects of overhead and complexity, the 2+2+2+2 solution is suggested to be directly used.
When N is other values, M still is 20, 21, 22, 23, . . . 2m, 2m<=N. It is set that
For example, N=16; when M=24=16, X4=1; X0=X1=X2=X3=0;
When N=10, N=X020+X121+X222+X323.
When M=8, X3=1; X1=1; X0=X2=0, which represents that the first type of TBs contains two, the second type of TBs contains two, and the third to eighth types of TBs each contain one TB.
When N=12, M=8, X3=1, X2=1, and the rest coefficients are 0, wherein X3=1 represents that each type has one TB when the TBs are classified into M=8 types, and X2=1 represents that each type is added with one TB when the TBs are classified into the first four types in the 8 types.
When N=16, taking 5 values for M needs 3 bits for representation, obviously some states are wasted, such that M<=8 is defined here. The above classification rule is unchanged, for example, when N=16, N=X020+X121+X222+X323, obviously X3=2, representing that the TBs are classified into 8 types of 2 identical TBs each. In summary, the method of classification is as follows:
With no constraint, the offset between the types may be large, and when the number of the TBs is large and the types are large, the needed signaling overhead is large. Under the condition of one type or two types, the method of embodiment 3 is suitable, and obviously excessive overhead is not suitable for signaling transmission when the TBs are classified into four types or eight types. Strong constraint conditions are added to achieve the effect of indicating various types of TBS.
Constraint conditions: binding is carried out on the basis of DCI modulation encoding and resource assignment field configuration of a certain type. One type corresponds to one TBS value. The binding method is as follows:
In this embodiment, a method for classifying multiple TBs during multi-TB scheduling is given. A DCI design method is provided for scheduling of multiple types of TBs. The total extra overhead includes 2-bit direction information and 2-bit classification information. Scheduling of the multiple types of TBs may be achieved by adding 4 bits in total.
