Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The method for determining the mapping type provided by the embodiment of the present invention can be applied to a terminal. The terminal may also be called user equipment (User Equipment, UE). In practical applications, the terminal may be a mobile phone, a tablet computer (Tablet PersonalComputer), a laptop computer (Laptop Computer), a personal digital assistant (Personal DigitalAssistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable Equipment (WearableDevice) or in-vehicle equipment, etc.

For the convenience of understanding, some contents involved in the embodiments of the present invention are described below:

For the URLLC service, in order to meet the requirements of low-latency and high-reliability service indicators, the Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (Physical Uplink Shared Channel) at the symbol level or Mini-Slot (Mini-Slot) level is used. Uplink Shared Channel, PUSCH) transmission, while using time domain repeat transmission.

For each transmission in the PUSCH repeated transmission, when encountering conflicting symbols (eg, DL symbols), time slot boundaries or uplink and downlink switching points, a complete repeated transmission may not be performed. At this time a transfer may need to be divided into multiple parts.

The transmission block size (Transmission Block Size, TBS) of a single transmission is determined according to a physical resource block (Physical Resource Block, PRB) within the time domain duration of one transmission.

For URLLC services, due to the influence of delay and reliability requirements, it is necessary to support repetition within or across slots. This will cause a transmission to be divided into several parts when it encounters a time slot boundary or an uplink and downlink switching point. The time domain length of each divided PUSCH transmission may be different, and the time domain length of the undivided transmission may be different. Are not the same.

The method for determining the mapping type provided in the embodiment of the present invention can be used in scenarios of repeated transmission of service channels, such as scenarios of repeated transmission of physical channels in a New Radio (New Radio, NR), scenarios of repeated transmission of URLLC services, and the like.

The following describes a method for determining a mapping type according to an embodiment of the present invention.

Referring to FIG. 1, FIG. 1 is a flowchart of a method for determining a mapping type provided by an embodiment of the present invention. As shown in Figure 1, the method for determining the mapping type may include the following steps:

Step 101: Receive indication information, where the indication information is used to indicate the mapping type of the traffic channel.

In this embodiment, the mapping type of the traffic channel may include at least a first mapping type and a second mapping type.

In specific implementation, the traffic channel may be represented as a Physical Shared Channel (Physical Shared Channel, PSCH). In this scenario, the mapping types of the traffic channels may include PSCH mapping type A (PSCH mapping type A) and PSCH mapping type B (PSCH mapping type B). Optionally, the first mapping type may be PSCH mapping type A, and the second mapping type may be PSCH mapping type B.

For PSCH mapping type A and PSCH mapping type B, the reference points of the corresponding demodulation reference signals (Demodulation Reference Signal, DMRS) in the time domain position are different.

Specifically, for PSCH mapping type A, the reference point of the time domain position of the DMRS is the start symbol of the time slot (Slot), and the start position of the time domain position of the first DMRS can be configured by the network side as the third or The fourth symbol is Orthogonal Frequency Division Multiplex (OFDM) symbol 2 or OFDM symbol 3 .

For PSCH mapping type B, the reference point of the time domain position of the DMRS is the start symbol of the scheduled PSCH resource, and the start position of the first DMRS time domain position may be the start symbol of the scheduled PSCH resource.

Further, the PSCH may be: PDSCH or PUSCH. Optionally, in the case where the PSCH is PDSCH, the first mapping type may be PDSCH mapping type A, and the second mapping type may be PDSCH mapping type B; in the case where PSCH is PUSCH, the first mapping type may be PUSCH mapping type A, the second mapping type may be PUSCH mapping type B.

In addition, in this embodiment of the present invention, the traffic channel may also be other channels, such as a physical broadcast channel (Physical Broadcast Channel, PBCH). The present invention does not limit the specific expression form of the traffic channel.

Step 102: In the case where the mapping type indicated by the indication information is the first mapping type, if the first transmission is performed through the traffic channel, determine the first transmission according to the time domain position of the first transmission The type of mapping to use.

In this embodiment, when the indication information indicates the first mapping type, when the terminal performs the first transmission through the traffic channel, the terminal may use the first mapping type for transmission, or may use the second mapping type for transmission , the specifically adopted mapping type needs to be further determined in combination with the time domain position of the first transmission.

In this embodiment, optionally, the first transmission may be: partial transmission or complete transmission of a repeated transmission.

Each repeated transmission may be referred to as a nominal transmission (Nominal Transmission).

During specific implementation, when the first transmission is a complete transmission of a repeated transmission, the first transmission is a complete, undivided repeated transmission.

When the first transmission is a partial transmission of a repeated transmission, the repeated transmission to which the first transmission belongs is divided, and specifically, the repeated transmission may be divided into at least two partial transmissions. It should be understood that the first transmission is any one of the divided transmissions.

In practical applications, when the time domain position of the repeated transmission encounters a slot boundary (Slot Boundary), an uplink and downlink switching point or a downlink time domain resource, the repeated transmission may be divided into at least two partial transmissions. For example, if the channel type of the traffic channel is an uplink channel, and the time domain position of a certain repeated transmission encounters downlink time domain resources, the repeated transmission may be divided into at least two partial transmissions.

In addition, the total number of time domain resources included in the at least two partial transmissions obtained by dividing the repeated transmission may be the same as or different from the number of time domain resources included before the repeated transmission is divided; the at least two partial transmissions obtained by dividing the repeated transmission The number of time domain resources included in each part of the transmission may be the same or different. For example, the repeated transmission includes 4 symbols before being divided, and the repeated transmission is divided into two partial transmissions. In one implementation, the two partial transmissions may each include 2 symbols; in another implementation, the two partial transmissions Transmissions can include different numbers of symbols.

For ease of understanding, an example is described below:

It is assumed that the terminal is configured on the network side to perform 3 repeated transmissions on the PUSCH, the starting position of the first repeated transmission is the first symbol of Slot1, that is, symbol 0, and each repeated transmission occupies 4 symbols. In addition, the symbol types of symbol 0 to symbol 13 of Slot1 are UUUF FFFF FUDD UU in sequence.

Based on the configuration on the network side, the time domain position of the first repeated transmission includes symbols 0 to 3 of Slot1, the second repeated transmission includes symbols 4 to 7 of Slot1, and the third repeated transmission includes symbols 8 to symbols of Slot1 11.

However, the terminal also needs to further judge whether each repeated transmission needs to be divided according to the time domain position of each repeated transmission determined based on the network side configuration.

It can be seen from the above content that the symbol types of symbols 0 to 3 of Slot1 are UUUF in sequence, and the time domain position of the first repeated transmission does not encounter the time slot boundary, uplink and downlink switching points and downlink symbols. Therefore, the first repeated transmission does not need to be divided, and the time domain position of the first repeated transmission includes symbol 0 to symbol 3 of Slot1.

The symbol types of symbols 4 to 7 of Slot1 are FFFF in sequence, and the time domain position of the second repeated transmission does not encounter the time slot boundary, uplink and downlink switching points, and downlink symbols. Therefore, the second repeated transmission does not need to be divided, and the second repeated transmission includes symbols 4 to 7 of Slot1.

The symbol types of symbol 8 to symbol 11 of Slot1 are FUDD in sequence, including the first time domain resource, and the time domain position of the third repeated transmission encounters a downlink symbol. Therefore, the third repeat transmission needs to be divided. Specifically, it can be divided into two partial transmissions, the time domain position of the first partial transmission may include symbol 8 and symbol 9 of Slot1, and the time domain position of the second partial transmission may include symbol 12 and symbol 13 of Slot1.

In the method for determining the mapping type in this embodiment, when the mapping type indicated by the indication information is the first mapping type, if the first transmission is performed through the traffic channel, the mapping type used for the first transmission needs to be further Combined with the time domain location determination of the first transmission, the mapping type used by the first transmission may be the first mapping type or may not be the first mapping type, so that the flexibility of determining the mapping type of the traffic channel can be improved. Spend.

In this embodiment, optionally, the determining of the mapping type used by the first transmission according to the time domain position of the first transmission includes at least one of the following:

In the case that the time domain position of the first transmission does not include the target position, determining that the mapping type adopted by the first transmission is the second mapping type;

In the case that the time domain position of the first transmission includes the target position, it is determined that the mapping type adopted by the first transmission is the first mapping type.

During specific implementation, in the case where it is determined that the mapping type used by the first transmission is the second mapping type, the first transmission may use the second mapping type for transmission.

In a case where it is determined that the mapping type used by the first transmission is the first mapping type, the first transmission may use the first mapping type for transmission.

In this way, not only the flexibility of selecting the mapping type of the service channel can be improved, but also the multiplexing capability of DMRSs of different terminals during repeated transmission can be improved, the orthogonality of the terminals can be ensured, and the network multiplexing capacity can be improved.

During specific implementation, the target position can be flexibly determined, which is not limited in the present invention.

Optionally, the target position is: all symbol positions of the first demodulation reference signal corresponding to the first mapping type in the first time slot, where the first time slot is where the first transmission is located. time slot.

In this way, when the time domain position of the first transmission does not include all the symbol positions of the first DMRS corresponding to the first mapping type, the second mapping type is used for transmission, and the position of the DMRS is re-determined, such as for For PUSCH, when the second mapping type is used for transmission, the DMRS is in the first symbol of the first transmission, so that the reliability of transmission can be improved.

In this embodiment, optionally, after the receiving the indication information, the method further includes:

In the case that the indication information indicates that the mapping type is the second mapping type, the first transmission uses the second mapping type for transmission.

That is, when the indication information indicates that the mapping type is the second mapping type, the terminal uses the second mapping type for transmission.

It should be noted that the various optional implementation manners introduced in the embodiments of the present invention may be implemented in combination with each other or independently if they do not conflict with each other, which are not limited in the embodiments of the present invention.

For ease of understanding, an example is described below:

The network side indicates (or notifies) the number of PSCH nominal transmissions (Nominal Transmission). Each repeated transmission can be called a nominal transmission. If a nominal transmission encounters conflicting symbols (for example, for PUSCH, the conflicting symbols are DL symbols), time slot boundaries, and uplink and downlink switching points, a nominal transmission needs to be divided into multiple parts. transmission.

The embodiment of the present invention provides a PSCH division scheme. For each actual transmission after division, the PSCH mapping type thereof is determined according to the position of the actual transmission.

For ease of understanding, the following description takes the PSCH transmission as the PUSCH transmission as an example:

Case 1. If the repeated transmission indicated by the network side is PUSCH mapping type A, then if a certain repeated transmission in a slot contains all the symbols of the first DMRS symbol, then the transmission uses PUSCH mapping type A, otherwise the PUSCH mapping type is used. B.

Case 2: If the repeated transmission indicated by the network side is PUSCH mapping type B, all transmissions use PUSCH mapping type B.

In view of the above situation one, the following description is given in conjunction with the accompanying drawings:

Embodiment 1

The network side instructs the terminal to use PUSCH mapping type A; the high-level parameter dmrs-TypeA-Position=pos2 (that is, OFDM symbol 2), and indicates a single-symbol DMRS, that is, the high-level parameter indicates that the starting position of the DMRS of Type A is symbol OFDM 2, And one DMRS occupies 1 column of symbols.

As shown in Figure 2, URLLC repeated transmissions indicate 3 nominal transmissions.

For nominal transmission 1, its time domain position includes symbol 10 to symbol 13 of Slot n, and based on dmrs-TypeA-Position, the symbol occupied by the first DMRS of Type A in Slot n is symbol 2. It can be seen that the nominal transmission 1 does not overlap all symbols of the first DMRS of Type A in its slot. Therefore, nominal transmission 1 uses PUSCH mapping type B, ie the first symbol of the DMRS in the first transmission, ie symbol 10 of Slot n.

For nominal transmission 2, its time domain position includes symbol 0 to symbol 3 of Slot n+1. Based on dmrs-TypeA-Position, the symbol occupied by the first DMRS of Type A in Slot n+1 is symbol 2, which shows that , the nominal transmission 2 overlaps with all symbols of the first DMRS of Type A in its slot. Therefore, nominal transmission 2 uses PUSCH mapping type A, that is, the third symbol of the DMRS in Slot n+1, that is, symbol 2.

For nominal transmission 3, it is divided into 2 actual transmissions, namely actual transmission 1 and actual transmission 2.

For actual transmission 1, its time domain position includes symbol 4 and symbol 5 of Slot n+1. Based on dmrs-TypeA-Position, the symbol occupied by the first DMRS of Type A in Slot n+1 is symbol 2, which shows that , the actual transmission 1 does not overlap all symbols of the first DMRS of Type A in its slot. Therefore, the actual transmission 1 uses the PUSCH mapping type B, that is, the first symbol of the DMRS in the actual transmission 1, that is, the symbol 4 of Slot n+1.

For actual transmission 2, its time domain position includes symbol 2 and symbol 3 of Slot n+2. Based on dmrs-TypeA-Position, the symbol occupied by the first DMRS of Type A in Slot n+2 is symbol 2, which shows that , the actual transmission 2 overlaps with all symbols of the first DMRS of Type A in its slot. Therefore, the actual transmission 2 uses PUSCH mapping type A, that is, the third symbol of the DMRS in Slot n+2, that is, symbol 2.

Embodiment 2

The network side instructs the terminal to use PUSCH mapping type A; the high-level parameter dmrs-TypeA-Position=pos2, the high-level parameter maxLength indicates len2, that is, the high-level parameter indicates that the starting position of the DMRS of Type A is symbol OFDM 2, and one DMRS can occupy at most 2-column symbols; Downlink Control Information (Downlink Control Information, DCI) or the configuration indication of the PUSCH configuration grant is a 2-symbol DMRS, which means that the DMRS symbols are 2-column symbols.

As shown in Figure 3, for nominal transmission 1, its time domain positions include symbols 11 to 13 of Slot n, and based on dmrs-TypeA-Position, the symbols occupied by the first DMRS of Type A in Slot n are symbols 2 and 13. Symbol 3, it can be seen that nominal transmission 1 does not overlap all symbols of the first DMRS of Type A in its slot. Therefore, nominal transmission 1 uses PUSCH mapping type B.

For nominal transmission 2, its time domain position includes symbol 0 to symbol 2 of Slot n+1, based on dmrs-TypeA-Position, the symbols occupied by the first DMRS of Type A in Slot n+1 are symbol 2 and symbol 3, It can be seen that the nominal transmission 2 does not overlap all symbols of the first DMRS of Type A in its slot, but only partially overlaps all symbols of the first DMRS of Type A in its slot. Therefore, nominal transmission 2 uses PUSCH mapping type B.

For nominal transmission 3, its time domain position includes symbol 3 to symbol 5 of Slot n+1, based on dmrs-TypeA-Position, the symbols occupied by the first DMRS of Type A in Slot n+1 are symbol 2 and symbol 3, It can be seen that the nominal transmission 3 does not overlap all symbols of the first DMRS of Type A in its slot, but only partially overlaps with all symbols of the first DMRS of Type A in its slot. Therefore, nominal transmission 3 uses PUSCH mapping type B.

In Figures 2 and 3, Symbol Index; Semi-Static SlotFormat.

The embodiments of the present invention can solve the requirement of UE supporting multiple services to ensure highly reliable service transmission, and can ensure DMRS multiplexing with other users in the network during repeated transmission, ensure the orthogonality of users, and improve network multiplexing capacity.
