Description
Technical Field
Embodiments of the present invention relate to the field of communications, and in particular, to a transmission processing method, apparatus, terminal, and medium.
Background
Compared with the prior Mobile Communication system, the fifth Generation Mobile Communication technology (5-Generation, 5G) needs to adapt to more diversified scenes and service requirements, the 5G scenes include enhanced Mobile Broadband (eMBB), Ultra-Reliable and low-latency Communication (UR-Reliable and L ow L activity Communications, UR LL C) and massive Machine Type Communication (mtc), and the scenes put forward requirements on the system such as high reliability, low latency, large bandwidth and wide coverage.
For some terminals, services with different numerical configurations (numerology) may be supported, and for UR LL C services, in order to meet low-latency and high-reliability service indicator requirements, Physical Downlink Shared Channel (PDSCH)/Physical Uplink Shared Channel (PUSCH) transmission at a symbol level or a mini-slot (mini-slot) level is used.
In the current transmission scheme, if a time slot does not satisfy the transmission condition, the transmission is ignored. For example, as shown in fig. 1, D in the semi-static slot format represents a downlink symbol, U represents an uplink symbol, and F represents a flexible (flexible) symbol, where the F symbol can be used for PUSCH transmission. Assuming that three PUSCH transmissions are required, only symbols 3 to 6 of slot n and symbols 3 to 6 of slot n +2 are actually used for transmission. Since symbol 3 to symbol 6 of slot n +1 are not consecutive 4 symbols available for PUSCH transmission, slot n +1 is not used for transmission. Therefore, the transmission delay of the current scheme is large, and the reliability is low.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a transmission processing method, which comprises the following steps:
if the nominal transmission meets a predetermined condition, the nominal transmission is divided (split) into at least one part to be transmitted, and the at least one part to be transmitted is used for transmission.
The nominal transmission may refer to a nominal transmission of a PUSCH or a PDSCH, the nominal transmission may be an initial transmission or a retransmission, and each nominal transmission may also be referred to as a repeat transmission for simplicity, for example: each nominal transmission occupies the same size of time domain resources (e.g., consisting of multiple consecutive symbols) that are used for PUSCH transmission or PDSCH transmission, which may be referred to as a time domain duration (duration).
As an embodiment, as shown in fig. 2, a transmission processing method includes:
and S101, if the nominal transmission meets a preset condition, dividing (split) the nominal transmission into at least one part to be transmitted.
And S102, transmitting according to the divided at least one part to be transmitted. I.e. the at least one portion to be transmitted is derived from a nominal transmission division.
It should be noted that the predetermined condition includes a combination of one or more of the following: encounter a slot boundary, encounter a collision symbol, encounter an uplink and downlink switching point.
The slot (slot) boundary is explained below, and for two adjacent slots n and n +1, the slot boundary is between the last symbol of slot n and the first symbol of slot n + 1.
Describing the collision symbols, if the uplink transmission encounters the symbols which can only carry out downlink transmission, the collision symbols are encountered; if the downlink transmission encounters a symbol that can only be transmitted in the uplink, a collision symbol is encountered.
The following describes an uplink/downlink switching point, which is a switching point between uplink and downlink. The symbol where the uplink and downlink switching point is located may be used for uplink transmission only; or, the symbol where the uplink and downlink switching point is located may be used for downlink transmission only; or, the symbol where the uplink and downlink switching point is located may be used for uplink transmission or downlink transmission.
The nominal transmission may be a PDSCH transmission or a PUSCH transmission.
In S102, for each part to be transmitted obtained by division, if the number of symbols of the part to be transmitted is greater than or equal to the minimum transmission length, the symbols of the part to be transmitted are available transmission symbols, that is, the symbols of the part to be transmitted can be used for transmission; and if the number of the symbols of the part to be transmitted is less than the minimum transmission length, the symbols of the part to be transmitted are unavailable transmission symbols, and the part to be transmitted is discarded.
For convenience of description, in the embodiment of the present invention, it is assumed that a Demodulation reference signal (DMRS) symbol does not transmit data, so that at least two symbols are required for one transmission, where one symbol is used for the DMRS and the other symbols are used for the data. Therefore, the minimum transmission length is 2, i.e. at least 2 characters are needed to achieve transmission. Of course, the minimum transmission length may be other values, for example, the minimum transmission length is an integer such as 3 or 4. The embodiment of the invention is also applicable to the case that the DMRS symbols transmit data.
In the embodiment of the invention, if the nominal transmission meets a time slot boundary, a collision symbol and an uplink and downlink switching point, the nominal transmission is divided into at least one part to be transmitted for transmission instead of neglecting the transmission, thereby improving the reliability of the transmission and shortening the time delay. Especially in the scenario of repeated transmission, the reliability of transmission can be effectively enhanced.
Fig. 3 is a flowchart illustrating a transmission processing method according to a second embodiment of the present invention. As shown in fig. 3, the transmission processing method includes:
s201, if the nominal transmission meets the preset condition, dividing the nominal transmission according to the total number of the symbols of the nominal transmission, and dividing the nominal transmission into at least one part to be transmitted. I.e., the nominal transmission is divided according to the total number of symbols of the nominal transmission.
Wherein the total number of symbols of the at least one portion to be transmitted is equal to the total number of symbols of the nominal transmission.
S202, judging each part to be transmitted obtained by dividing as follows: if the symbol of the part to be transmitted is an available transmission symbol, the symbol of the part to be transmitted can be used for transmission, and if the symbol of the part to be transmitted is an unavailable transmission symbol, the transmission part is discarded.
An embodiment of the present invention will be described in detail below with reference to the example of fig. 4.
As shown in fig. 4, three repetitions are required, nominal transmission 1 using symbols 3 to 6 of slot n and nominal transmission 2 using symbols 9 to 12 of slot n. The total number of symbols of the nominal transmission 1 and the total number of symbols of the nominal transmission 2 are both 4, and among the 4 symbols, there is one symbol for DMRS and three symbols for data. And nominal transmission 1 is actual transmission 1 and nominal transmission 2 is actual transmission 2.
When nominal transmission 3 is made, nominal transmission 3 encounters slot boundaries for slot n and slot n +1, determining that the total number of symbols for nominal transmission 3 is the same as the total number of symbols for nominal transmission 1, and the total number of symbols is 4.
The nominal transmission 3 is divided according to the total number of symbols of the nominal transmission 3. And if the total number of the divided at least one part to be transmitted is equal to the total number of the symbols of the nominal transmission 3, stopping dividing, namely dividing to obtain 3 parts to be transmitted, namely a part 1, a part 2 and a part 3.
For the part 1 and the part 3 obtained by division, since the number of symbols of the part 1 is smaller than the minimum transmission length (the minimum transmission length is 2 in this embodiment), the symbols of the part 1 are unavailable transmission symbols, and the part 1 is discarded; similarly, part 3 is discarded. For the divided part 2, since the number of symbols of the part 2 is equal to the minimum transmission length, the symbols of the part 2 are available transmission symbols, and the part 2 is used for actual transmission.
From the above, it can be seen that nominal transmission 3 actually uses symbols 5 and 6 of slot n +1 for transmission, i.e. actual transmission 3.
Fig. 5 is a flowchart illustrating a transmission processing method according to a third embodiment of the present invention. As shown in fig. 5, the transmission processing method includes:
and S301, if the nominal transmission meets the preset condition, dividing the nominal transmission.
S302, each division is carried out to obtain a part to be transmitted, and whether the symbol of the part to be transmitted is an available transmission symbol is determined.
S303, determining whether the division is finished according to the total number of available transmission symbols in the divided parts to be transmitted so as to obtain at least one part to be transmitted; wherein a total number of available transmission symbols in the at least one portion to be transmitted is less than or equal to a total number of symbols for a nominal transmission.
And S304, transmitting based on the available transmission symbols in the at least one part to be transmitted.
Wherein, each part to be transmitted obtained by division is judged as follows: if the symbol of the part to be transmitted is an available transmission symbol, the symbol of the part to be transmitted can be used for transmission, and if the symbol of the part to be transmitted is an unavailable transmission symbol, the transmission part is discarded.
In S303 of the embodiment of the present invention, there are two ways to determine whether the division is completed.
In a first mode
And if the total number of the available transmission symbols in the divided part to be transmitted is equal to the total number of the symbols in the nominal transmission, the division is finished.
The following describes the transmission processing scheme corresponding to equation one in detail by way of an example.
As shown in fig. 6, three repeated transmissions are required, nominal transmission 1 using symbols 3 to 6 of slot n (nominal transmission 1 is actual transmission 1), and nominal transmission 2 using symbols 9 to 12 of slot n (nominal transmission 2 is actual transmission 2). The total number of symbols of the nominal transmission 1 and the total number of symbols of the nominal transmission 2 are both 4, and among the 4 symbols, there is one symbol for DMRS and three symbols for data.
When making nominal transmission 3, nominal transmission 3 encounters the slot boundary for slot n and slot n +1 and the uplink and downlink switching point for slot n + 1. And dividing the nominal transmission 3, dividing a part to be transmitted each time, and determining whether the symbol of the part to be transmitted is an available transmission symbol.
When the division is performed for the first time, the part 1 is divided, and since the number of symbols of the part 1 is smaller than the minimum transmission length (the minimum transmission length is 2 in this embodiment), the symbols of the part 1 are unusable transmission symbols, and the part 1 is discarded.
The subsequent symbols are divided a second time to form part 2. Since the number of symbols of the part 2 is equal to the minimum transmission length, the symbols of the part 2 are available transmission symbols. And since the total number of available transmission symbols that have been divided is not equal to the total number of symbols for nominal transmission 3, the following symbols are divided, i.e., the third division is performed.
The third division into parts 3, the symbols of part 3 are available transmission symbols since the number of symbols of part 3 is equal to the minimum transmission length. And the total number of available transmission symbols divided is the sum of the symbols of part 2 and the symbols of part 3, and the total number of available transmission symbols divided is equal to the total number of symbols of nominal transmission 3, and thus, the division is completed.
Thus, for the nominal transmission 3, the symbols 5, 6, 12 and 13 of the slot n +1 are actually used for transmission, i.e. the actual transmission 3 and the actual transmission 4, so that the total number of available transmission symbols is divided to be equal to the total number of symbols for the nominal transmission.
Mode two
The division is determined to be complete if the absolute value of the difference between the total number of symbols for the nominal transmission and the total number of available transmission symbols in the divided portion to be transmitted is less than the minimum transmission length. I.e. in case the absolute value of the difference between the total number of symbols for the nominal transmission and the total number of available transmission symbols in the divided part to be transmitted is smaller than the minimum transmission length, the nominal transmission is divided.
For example, the division is determined to be completed if the difference obtained by subtracting the total number of available transmission symbols obtained by the division from the total number of symbols for the nominal transmission is smaller than the minimum transmission length.
The transmission processing scheme corresponding to the second scheme will be described in detail below by way of an example.
As shown in fig. 7, three repeated transmissions are required, and nominal transmission 1 is performed using symbols 3 to 6 of slot n (nominal transmission 1 is actual transmission 1). The total number of symbols for nominal transmission 1 is 4, and among the 4 symbols, there is one symbol for DMRS and three symbols for data. The total number of symbols for nominal transmission 2 and nominal transmission 3 is also 4.
When nominal transmission 2 is carried out, if the nominal transmission 2 meets the time slot boundary of the time slot n and the time slot n +1 and the uplink and downlink switching point of the time slot n +1, the nominal transmission 2 is divided, a part to be transmitted is divided each time, and whether the symbol of the part to be transmitted is an available transmission symbol is determined.
When the division is performed for the first time, the part 1 is divided, and since the number of symbols of the part 1 is smaller than the minimum transmission length (the minimum transmission length is 2 in this embodiment), the symbols of the part 1 are unusable transmission symbols, and the part 1 is discarded.
The subsequent symbols are divided a second time to form part 2. Since the number of symbols of the part 2 is greater than the minimum transmission length, the symbols of the part 2 are available transmission symbols. And the division is completed because the difference (4-3 ═ 1, i.e. the difference is 1) obtained by subtracting the total number of available transmission symbols obtained by division from the total number of symbols of the nominal transmission 2.
In the transmission processing scheme corresponding to the second mode, the absolute value of the difference between the total number of the symbols in the nominal transmission and the total number of the available transmission symbols in the divided part to be transmitted is smaller than the minimum transmission length, and the division is finished, so that the number of the divided unavailable transmission symbols can be reduced, and the influence on the subsequent transmission is avoided. In fig. 7, it is assumed that the division is continued after the division of the part 2, the part 3 is divided, the symbol of the part 3 is the symbol 2 of the slot n +2, but the symbol of the part 3 is an unavailable transmission symbol, the part 3 needs to be discarded, and the transmission of the nominal transmission 3 is affected. Thus in fig. 7, dividing after dividing part 2 can avoid dividing part 3 for nominal transmission 2 from affecting the transmission of nominal transmission 3.
In addition, in S301, the unavailable transmission symbols may be skipped before the nominal transmission is divided.
As shown in fig. 8, nominal transmission 2 encounters a slot boundary, skips an unavailable transmission symbol, i.e., skips symbol 13 of slot n, and then divides into portion 1, the number of symbols of portion 1 being greater than the minimum transmission length, so the symbols of portion 1 are available transmission symbols. And the division is completed because the difference obtained by subtracting the total number of available transmission symbols obtained by division from the total number of symbols of the nominal transmission 2 (4-3 is 1, i.e. the difference is 1), is smaller than the minimum transmission length (in this embodiment, the minimum transmission length is 2). Thus, the nominal transmission 2 is divided into a portion, portion 1, and the symbols of portion 1 are used for transmission, and portion 1 is the actual transmission.
Fig. 9 is a flowchart illustrating a transmission processing method according to a fourth embodiment of the present invention. As shown in fig. 9, the transmission processing method includes:
s401, if the nominal transmission meets the preset conditions, dividing the nominal transmission according to the total number of the symbols used for data of the nominal transmission, and dividing the nominal transmission into at least one part to be transmitted. I.e., the nominal transmission is divided according to the total number of symbols used for data in the nominal transmission.
Wherein a total number of symbols for data in the available transmission symbols in the at least one portion to be transmitted is equal to a total number of symbols for data in the nominal transmission.
It should be noted that, in one transmission including symbols for DMRS and symbols for data, in an embodiment of the present invention, the total number of symbols for data in the available transmission symbols obtained by dividing is equal to the total number of symbols for data in the nominal transmission.
S402, judging each part to be transmitted obtained by dividing as follows: if the symbol of the part to be transmitted is an available transmission symbol, the symbol of the part to be transmitted can be used for transmission, and if the symbol of the part to be transmitted is an unavailable transmission symbol, the transmission part is discarded.
The following describes an embodiment of the present invention in detail by way of an example of fig. 10.
As shown in fig. 10, when the nominal transmission 2 is performed, the nominal transmission 2 encounters slot boundaries of the slot n and the slot n +1, determines that the total number of symbols for data of the nominal transmission 2 is the same as the total number of symbols for data of the nominal transmission 1, and the total number of symbols for data is all 3.
For the divided part 1, since the number of symbols of the part 1 is smaller than the minimum transmission length (the minimum transmission length is 2 in this embodiment), the symbols of the part 1 are unusable transmission symbols, and the part 1 is discarded. For the divided parts 2 and 3, since the number of symbols of the part 2 is greater than the minimum transmission length and the number of symbols of the part 3 is equal to the minimum transmission length, the symbols of the parts 2 and 3 are available transmission symbols, and the actual transmission is performed using the parts 2 and 3.
As can be seen from the above, nominal transmission 2 actually uses symbols 11 through 13 of slot n +1, symbols 2 and 3 of slot n +2 for transmission, i.e., actual transmission 2 and actual transmission 3.
For the transmission processing method of any one of the above embodiments of the present invention, the transmission processing method may further include:
the first designated transmission is discarded if the initial symbol of the first designated transmission is after the end time of the predetermined transmission time interval. Wherein the first designated transmission comprises: nominal transmission and/or division of the resulting portion to be transmitted. The predetermined transmission time interval is a maximum transmission time interval from a last symbol of the control resource set in which the uplink grant is received.
For example, as shown in fig. 11, a nominal transmission 2 is divided into a part 1, a part 2 and a part 3, a symbol of the part 1 and a symbol of the part 3 are both unavailable transmission symbols, the part 1 and the part 3 are discarded, and the part 2 is actually transmitted. The network can be configured: maximum allowed transmission time interval t from the last symbol of Control resource set (CORESET) receiving uplink grant1Discard t 13 after the last symbol. Let t1The last symbol is followed by the available transmission symbols that are divided and discarded as well. I.e. discard t1The last symbol of the set of symbols and dividing the available transmission symbols.
As an embodiment of the present invention, the transmission processing method may further include:
discarding a portion of the second designated transmission that is not within the predetermined transmission time interval if another portion of the second designated transmission is not within the predetermined transmission time interval; wherein the second designated transmission comprises: nominal transmission and/or division of the resulting portion to be transmitted. The predetermined transmission time interval is a maximum transmission time interval from a last symbol of the control resource set in which the uplink grant is received.
For a certain part to be transmitted obtained by division, if the symbols of the part to be transmitted are available transmission symbols, and at least 2 symbols of the part to be transmitted are in the maximum transmission time interval, and other symbols of the part to be transmitted are after the last symbol of the maximum transmission time interval, then the symbols after the last symbol of the maximum transmission time interval are discarded.
As shown in fig. 12, the first two symbols of nominal transmission 3 are at a maximum transmission time interval t1Within the last two symbols of nominal transmission 3 in the maximum transmission time interval t1Otherwise, the last two symbols of the nominal transmission 3 (or punctured) are discarded and only the first two symbols of the nominal transmission 3 are used for transmission. .
The transmission processing method according to any one of the embodiments of the present invention is applied to a terminal, and the terminal may be enabled to execute the transmission processing method in a network configuration manner. Moreover, for convenience of description, in the above-mentioned figures, the flexible symbol F where the uplink and downlink switching point is located may be used for uplink transmission, and in practical application, the flexible symbol F where the uplink and downlink switching point is located may not be used for uplink transmission, that is, may be used for downlink transmission only.
With respect to the transmission processing methods shown in fig. 3, 5, and 6, the transmission processing method shown in fig. 3 achieves the shortest total transmission time, the transmission processing method shown in fig. 5 achieves the next lowest total transmission time, and the transmission processing method shown in fig. 6 achieves the next lowest total transmission time.
The transmission processing method shown in fig. 6 preferably implements the code rate, the transmission processing method shown in fig. 5 implements the code rate again, and the transmission processing method shown in fig. 3 implements the code rate again.
The nominal transmission and the actual transmission in the above-described embodiments of the invention are further described below.
The number of times the network indicates or informs the nominal transmission (nominal transmission) may not be equal to the number of actual transmissions. As shown in fig. 13, two repeated transmissions, namely nominal transmission 1 and nominal transmission 2, are performed, each nominal transmission lasts for 4 symbols, the nominal transmission number is 2, all nominal transmissions do not cross the boundary or the uplink and downlink switching point, and therefore the actual transmission number is 2.
As shown in fig. 14, 4 repeated transmissions are made, each lasting 4 symbols, with a nominal number of transmissions of 4. When there is a nominal transmission crossing a slot boundary or an uplink and downlink switching point, one nominal transmission is divided into 2 actual transmissions, i.e., nominal transmission 3 is divided into 2 actual transmissions. Thus, the actual number of transmissions is 5.
