Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present invention are described below with reference to the accompanying drawings. The embodiment provided by the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, or an Evolved Long term evolution (lte) system, or a subsequent Evolved communication system.

Fig. 1 is a structural diagram of a network system according to an embodiment of the present invention, as shown in fig. 1, including a terminal 11 and a network-side device 12, where the terminal 11 may be a mobile communication device, for example: the terminal may be a Mobile phone, a tablet personal Computer (tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and the specific type of the terminal 11 is not limited in the embodiments of the present invention. The network side device 12 may be a 5G network side device (e.g., a gNB, a 5G NR NB), or may be a 4G network side device (e.g., an eNB), or may be a 3G network side device (e.g., an NB), or a network side device in a subsequent evolved communication system, and so on, it should be noted that a specific type of the network side device 12 is not limited in the embodiment of the present invention.

Before the technical solution of the embodiment of the present invention is explained in detail, a simple introduction is made to a Multi-PUSCH scheduling mechanism.

In future communication systems, an Unlicensed Band (Unlicensed Band) may be used as a supplement to a licensed Band (licensed Band) to expand the capacity of a service. Since the unlicensed frequency band is shared by multiple technologies (RATs), for example, Wi-Fi, radar, LTE (Long Term Evolution) based Licensed spectrum Assisted Access to unlicensed spectrum (LTE-based Licensed-Assisted Access), and the like. Therefore, the unlicensed band must follow certain rules when it is used to ensure that all devices can fairly share the resource, such as Listen Before Talk (LBT), Maximum Channel Occupancy Time (MCOT), and so on. When a transmission node needs to send information, it is required to perform LBT on a specified wireless channel first, and perform Energy Detection (ED) on the surrounding wireless transmission environment, when the Energy is lower than a certain threshold, the channel is judged to be idle, at this time, transmission can be started, and after the transmission node starts transmission, the occupied channel time cannot exceed the MCOT. The transmission node can be a network side device, a terminal, a Wi-Fi AP and the like.

In LTE-LAA, a concept of Multiple PUSCH Subframe scheduling is introduced, and a single DCI (e.g. DCIFormat 0B, DCI Format 4B) may schedule 1 to Multiple subframes (subframes) consecutive in time for transmitting PUSCH, so as to save overhead of sending DCI by a network side device, reduce the requirement of a terminal to perform LBT, and reduce the requirement of introducing Multiple uplink and downlink switching points in a COT initiated by the network side device.

The standard advancement of NR-U also introduces a concept similar to Multiple PUSCH Subframe scheduling in LTE-LAA. Based on the flexibility of NR in time domain resource allocation, Subframe can also be replaced by Slot or Mini-Slot. That is, a single DCI may schedule 1 to multiple slots or Mini-slots for transmission of PUSCH. In the NR-U, an NR downlink aperiodic CSI reporting mechanism may be used, and a downlink aperiodic CSI reporting mechanism is introduced, that is, the network side device may use the uplink scheduling DCI to trigger the downlink aperiodic CSI to be transmitted on the scheduled PUSCH as required, and the terminal may use the scheduled PUSCH to carry the triggered aperiodic CSI. If the NR-U follows the corresponding scheme in the multiple pusch Subframe scheduling in LTE-LAA, there will be the following problems:

first, when the number of slots scheduled by a single DCI is less than or equal to 2, the terminal selects a PUSCH corresponding to the last Slot, and when only a small number of time domain symbols are occupied in the last Slot, the data size corresponding to CSI information may not be accommodated.

Secondly, when the number of the slots scheduled by the single DCI is larger than 2, the terminal selects the PUSCH corresponding to the second last Slot, the LBT failure probability of the second last Slot is higher than that of the last Slot at the moment, the best selection is not always achieved, and meanwhile the second last Slot may not meet the CSI preparation time requirement.

Thirdly, when the Slot granularity is based on the Mini-Slot granularity, one to multiple PUSCHs can be configured in one Slot, and when multiple PUSCHs exist in the Slot selected by the terminal, the terminal and the network side equipment do not know how to determine or select a certain PUSCH to carry the aperiodic CSI.

In the NR-U, it can be known that, when a single DCI schedules multiple slots or Mini-slots, that is, schedules multiple PUSCHs, how to determine which PUSCH or PUSCHs the terminal uses to carry the triggered aperiodic CSI is not provided at present, which may cause the success rate and reliability of aperiodic CSI reporting to be not guaranteed, thereby affecting the performance of the communication system.

In view of this, an embodiment of the present invention provides a network system as shown in fig. 1, and provides an uplink transmission method applied to the network system. As shown in fig. 2, the method comprises the steps of:

step 201: the network side equipment transmits DCI, wherein the DCI is used for indicating M PUSCHs, and M is an integer greater than or equal to 1.

Step 202: and the terminal receives the DCI sent by the network side equipment.

Step 203: and the terminal selects a target PUSCH from the M PUSCHs, wherein the target PUSCH is used for carrying the aperiodic CSI.

The terminal can select a target PUSCH from M PUSCHs based on the bearer requirement of the aperiodic CSI, can also select the target PUSCH from the M PUSCHs according to the indication of the network side equipment, and can also select the target PUSCH from the M PUSCHs based on the LBT condition of the terminal. By comprehensively considering the above aspects, the target PUSCH selected by the terminal can meet the bearing requirement of the aperiodic CSI as much as possible, and the success rate and reliability of the aperiodic CSI reporting are improved.

Step 204: and the terminal sends the aperiodic CSI on the target PUSCH.

Step 205: and the network side equipment receives the aperiodic CSI on the target PUSCH.

Fig. 3 is a flowchart of an uplink transmission method according to an embodiment of the present invention. As shown in fig. 3, the uplink transmission method is applied to a terminal, and the method includes the following steps:

step 301: receiving DCI sent by a network side device, wherein the DCI is used for indicating M PUSCHs, and M is an integer greater than or equal to 1.

The M PUSCHs may be understood as M PUSCHs in consecutive time domain resources, and a single time domain resource may include one or more PUSCHs. Assuming that the network side device schedules the terminal to transmit a plurality of PUSCHs starting from a certain symbol in the Slot n + k in the Slot n by using a single DCI, each PUSCH corresponds to all or part of the symbols of a single Slot, and there may be 1 or more PUSCHs in the single Slot.

Step 302: selecting a target PUSCH from the M PUSCHs, the target PUSCH being used to carry aperiodic CSI.

The target PUSCH may be one PUSCH among the M PUSCHs, may be a plurality of PUSCHs among the M PUSCHs, or may be all PUSCHs among the M PUSCHs.

In the selection of the target PUSCH, the terminal may select from M PUSCHs based on the bearer requirement of the aperiodic CSI, may select from M PUSCHs according to the instruction of the network side device, or may select from M PUSCHs based on the LBT condition of the terminal. No matter what selection mode is adopted, the target PUSCH selected by the terminal can meet the bearing requirement of the aperiodic CSI as much as possible, so that the success rate and the reliability of reporting the aperiodic CSI are improved, and the performance of a communication system is improved.

The loading requirement of the aperiodic CSI may include at least one of a data volume requirement of the aperiodic CSI and a processing time requirement of the aperiodic CSI, and thus, the target PUSCH may satisfy at least one of the data volume requirement of the aperiodic CSI and the processing time requirement of the aperiodic CSI. It should be noted that the target PUSCH selected by the terminal from the M PUSCHs may not meet the data amount requirement of the aperiodic CSI nor the processing time requirement of the aperiodic CSI.

The M PUSCHs indicated by the DCI may be used to carry transport blocks, that is, the M PUSCHs are used to carry transport blocks, and some or all of the M PUSCHs are simultaneously used to carry aperiodic CSI; or, the M PUSCHs may not be used to carry the transport block, that is, the M PUSCHs are only used to carry the aperiodic CSI. Therefore, the data amount of the aperiodic CSI may be required to comprehensively consider factors such as the data amount carried by the PUSCH, the data amount of the aperiodic CSI, and the code rate reduction factor of the aperiodic CSI information.

In the following, various manners of selecting a target PUSCH by a terminal in the embodiment of the present invention are specifically described in terms of data amount carried by the M PUSCHs, and in terms of two aspects that the M PUSCHs are used for carrying a transport block and aperiodic CSI, and the M PUSCHs are used for carrying only aperiodic CSI.

In a first aspect: the M PUSCHs are used for carrying a transport block and aperiodic CSI, that is, the M PUSCHs are used for carrying both aperiodic CSI and transport block.

The first method is as follows: and the terminal selects N PUSCHs with the most late time from the M PUSCHs as the target PUSCHs, wherein N is an integer greater than or equal to 1.

In this way, the terminal may fixedly select one or more PUSCHs with the most posterior time positions as target PUSCHs for carrying aperiodic CSI.

Since the CSI calculation time or the CSI preparation time specified in the NR is generally longer than the PUSCH preparation time, one or more PUSCHs with earlier time positions in the M PUSCHs may not necessarily satisfy the requirements of the CSI calculation time or the CSI preparation time. In view of this, in the method, one or more PUSCHs with the most posterior time positions are selected as the target PUSCHs in a fixed manner, so that the target PUSCHs selected by the terminal can meet the processing time requirement of the aperiodic CSI as much as possible, and the success rate and reliability of the aperiodic CSI reporting are improved. On the basis of the data volume requirement of the aperiodic CSI, the network side device can implement the scheduling only by ensuring that one or more PUSCHs with the most backward time positions in the M PUSCHs meet the data volume requirement of the aperiodic CSI during uplink scheduling.

The second method comprises the following steps: and the terminal selects N PUSCHs with the most rear time from P PUSCHs as the target PUSCHs, the P PUSCHs are the PUSCHs which meet at least one of the data volume requirement of the aperiodic CSI and the processing time requirement of the aperiodic CSI in the M PUSCHs, and N is an integer which is greater than or equal to 1.

In this manner, the terminal may first screen P PUSCHs that satisfy at least one of the data amount requirement of the aperiodic CSI and the processing time requirement of the aperiodic CSI from the M PUSCHs, and then select N PUSCHs with the most recent time as target PUSCHs from the screened P PUSCHs. Therefore, the target PUSCH is selected after the screening, and the success rate and the reliability of the aperiodic CSI reporting can be effectively improved.

Optionally, the P PUSCHs are PUSCHs that satisfy the data volume requirement of the aperiodic CSI among the M PUSCHs. That is to say, the terminal firstly screens P PUSCHs meeting the data volume requirement of the aperiodic CSI from the M PUSCHs, and then selects N PUSCHs with the most late time from the screened P PUSCHs as target PUSCHs. In this way, since the P PUSCHs screened all meet the data volume requirement of the aperiodic CSI, then the N PUSCHs with the most late time are selected from the P PUSCHs as the target PUSCHs, and the processing time requirement of the aperiodic CSI is further considered on the basis of meeting the data volume requirement of the aperiodic CSI, so that the target PUSCHs selected by the terminal can meet the data volume requirement of the aperiodic CSI and the processing time requirement of the aperiodic CSI, and the success rate and the reliability of reporting the aperiodic CSI are further improved.

The third method comprises the following steps: and the terminal selects a target PUSCH from the M PUSCHs according to the indication of the network side equipment.

In this way, the network side device may indicate a PUSCH actually carrying aperiodic CSI (i.e. a target PUSCH), for example, the network side device may indicate the target PUSCH in DCI, the network side device may extend the indication content of the existing "CSI request" field in DCI, or introduce a new field in DCI to independently indicate.

The network side device may indicate the target PUSCH in the following manner:

first, the network side device may indicate an index corresponding to the target PUSCH.

Secondly, the network side device may indicate a time domain resource offset corresponding to the target PUSCH, and the network side device may indicate the time domain resource offset in each CSI triggerring state. Each CSI triggering state corresponds to each aperiodic CSI triggering state, and the CSI triggering states can be configured to the terminal in advance by the network side equipment in a mode of high-level signaling through a CSItringing state list. When uplink scheduling is carried out at a certain time, the network side equipment indicates a specifically triggered aperiodic CSI trigger state in a CSI request field of DCI.

The time domain resource offset may be a Symbol (Symbol) offset or a Slot (Slot) offset.

If the time domain resource offset is a symbol offset, the PUSCH including the symbol indicated by the symbol offset may be the target PUSCH. The reference starting position of the symbol offset may be a symbol next to a last symbol occupied by a PDCCH (physical downlink control channel) carrying DCI.

If the time domain resource offset is a Slot offset, the reference starting position of the Slot offset may be a Slot where the PDCCH carrying the DCI is located.

The time slot corresponding to the time slot offset indicated by the network side equipment may include one or more PUSCHs, and the terminal directly takes a single PUSCH as a target PUSCH under the condition that the time slot corresponding to the time slot offset indicated by the network side equipment only contains the single PUSCH; when the slot corresponding to the slot offset indicated by the network side device includes a plurality of PUSCHs, the terminal may select one of the PUSCHs as the target PUSCH from the plurality of PUSCHs included in the slot.

Further, when the time slot corresponding to the time slot offset indicated by the network side device includes a plurality of PUSCHs, the terminal may select the PUSCH carrying the largest data amount from the plurality of PUSCHs as the target PUSCH; alternatively, the terminal may select, as the target PUSCH, the PUSCH that satisfies the data amount requirement of the aperiodic CSI and is most delayed from among the plurality of PUSCHs.

Further, when the slot corresponding to the slot offset instructed by the network side device includes a plurality of PUSCHs and S (S is an integer greater than 1) PUSCHs with the largest bearer data amount exist in the plurality of PUSCHs, the terminal may select a PUSCH with the most late time from the S PUSCHs with the largest bearer data amount as the target PUSCH.

The method is as follows: and the terminal selects T PUSCHs from L PUSCHs after the successful access time as the target PUSCHs.

Wherein the M PUSCHs include the L PUSCHs, and L and T are integers greater than or equal to 1.

In this way, the terminal selects the target PUSCH according to the LBT condition. And the terminal selects T PUSCHs as target PUSCHs from L PUSCHs after the successful access time under the condition that the LBT is successful.

In this way, the network side device may determine, through detection, L PUSCHs transmitted after the terminal successfully accesses the time, then select T PUSCHs from the L PUSCHs, and receive the multiplexed aperiodic CSI on the T PUSCHs, and the network side device may consider that the aperiodic CSI is no longer carried on the remaining PUSCHs. Here, the detection manner of the network side device may be blind detection, and the reliability of the blind detection of the network side device may affect the understanding consistency of the terminal and the network side device on whether the aperiodic CSI is carried on the remaining PUSCH. When the two are not consistent with the above understanding, PUSCH decoding may fail.

The T PUSCHs (i.e., target PUSCHs) may be T PUSCHs that are most advanced in time among the L PUSCHs, or may be T PUSCHs that are most advanced in time among the L PUSCHs. For example, the target PUSCH may be the first PUSCH among the L PUSCHs, the last PUSCH, the first PUSCHs among the L PUSCHs, or the last PUSCHs among the L PUSCHs. Where T is the minimum of the number of protocol specifications (or higher layer configurations) and the number of PUSCHs successfully accessed and satisfying the above requirements.

Optionally, the L PUSCHs are actually transmitted PUSCHs, or the L PUSCHs are actually transmitted PUSCHs that satisfy at least one of a data amount requirement of the aperiodic CSI and a processing time requirement of the aperiodic CSI.

In this scheme, in the former scheme, the terminal directly selects T PUSCHs as target PUSCHs from L PUSCHs actually transmitted after the successful access time. For the latter, the terminal firstly screens L actually transmitted PUSCHs which meet at least one of the data volume requirement and the processing time requirement of the aperiodic CSI from the PUSCHs after the successful access time, and then selects T PUSCHs from the L PUSCHs as target PUSCHs. In the latter case, the target PUSCH is selected after the screening, so that the success rate and the reliability of the aperiodic CSI reporting can be effectively improved.

The fifth mode is as follows: and the terminal selects all PUSCHs from L PUSCHs after the successful access time as the target PUSCHs.

Wherein the M PUSCHs include the L PUSCHs, and L is an integer greater than or equal to 1.

In this scheme, in the former scheme, the terminal directly selects all PUSCHs as target PUSCHs from L PUSCHs actually transmitted after the successful access time. For the latter, the terminal firstly screens L actually transmitted PUSCHs which meet at least one of the data volume requirement and the processing time requirement of the aperiodic CSI from the PUSCHs after the successful access time, and then selects all PUSCHs in the L PUSCHs as target PUSCHs. In the latter case, the L PUSCHs subjected to the screening can better meet the bearing requirements of the aperiodic CSI, so that the success rate and reliability of the aperiodic CSI reporting can be effectively improved.

In this way, the terminal selects all PUSCHs as target PUSCHs from L PUSCHs after the successful access time, so that the transmission reliability of the aperiodic CSI can be ensured, and the problem of inconsistent understanding of resource mapping of the PUSCHs on both sides of the terminal and the network side device does not exist.

In a second aspect: the M PUSCHs are only used for carrying aperiodic CSI, that is, the M PUSCHs are used for carrying aperiodic CSI and are not used for carrying transport blocks. The network side equipment can indicate M PUSCHs capable of meeting the aperiodic CSI data volume requirement and the aperiodic CSI processing time requirement through the DCI.

The first method is as follows: and the terminal selects Y PUSCHs as the target PUSCHs from K PUSCHs actually transmitted after the successful access moment.

Wherein the M PUSCHs include the K PUSCHs, and K and Y are integers greater than or equal to 1.

In this way, the terminal selects the target PUSCH according to the LBT condition. And the terminal selects Y PUSCHs as target PUSCHs from K PUSCHs actually transmitted after the successful access moment under the condition that the LBT is successful.

In this way, the network side device may determine, through detection, K PUSCHs actually transmitted after the terminal successfully accesses the time, then select Y PUSCHs from the K PUSCHs, and receive the aperiodic CSI carried on the Y PUSCHs, and the network side device may consider that the aperiodic CSI is no longer carried on the remaining PUSCHs. Here, the detection manner of the network side device may be blind detection, and the reliability of the blind detection of the network side device may affect the understanding consistency of the terminal and the network side device on whether the aperiodic CSI is carried on the remaining PUSCH. When the two are not consistent with the above understanding, PUSCH decoding may fail.

The Y PUSCHs (i.e., target PUSCHs) may be Y PUSCHs that are most advanced in time among the K PUSCHs. For example, the target PUSCH may be the first PUSCH among the K PUSCHs, or may be the first plurality of PUSCHs among the K PUSCHs. Wherein Y is the minimum of the number of protocol specifications (or higher layer configuration) and the number of PUSCHs successfully accessed and satisfying the above requirements.

The second method comprises the following steps: and the terminal selects all PUSCHs as the target PUSCHs from K PUSCHs actually transmitted after the successful access moment.

Wherein the M PUSCHs include the K PUSCHs, and K is an integer greater than or equal to 1.

In this way, the terminal takes all PUSCHs actually transmitted after the successful access time as target PUSCHs, so that the transmission reliability of the aperiodic CSI can be ensured, and the problem of inconsistent understanding of resource mapping of the PUSCHs on both sides of the terminal and the network side device can be avoided.

By combining the above embodiments, in the selection of the target PUSCH, the terminal may take comprehensive consideration from the aspects of the bearer requirement of the aperiodic CSI, the indication of the network side device, the terminal LBT condition, and the like, so that the target PUSCH selected by the terminal can meet the bearer requirement of the aperiodic CSI as much as possible, the success rate and reliability of the aperiodic CSI report are improved, and the performance of the communication system is improved.

Fig. 4 is a flowchart of an uplink transmission method according to an embodiment of the present invention. As shown in fig. 4, the uplink transmission method is applied to a network side device, and the method includes the following steps:

step 401: sending Downlink Control Information (DCI) to a terminal, wherein the DCI is used for indicating M Physical Uplink Shared Channels (PUSCHs), and M is an integer greater than or equal to 1;

step 402: receiving aperiodic Channel State Information (CSI) on a target PUSCH, the M PUSCHs including the target PUSCH.
