All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means at least one of the connected objects, e.g., a and/or B, meaning that it includes a single a, a single B, and that there are three cases of a and B.

In embodiments of the invention, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts 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 (Evolved Long Term Evolution, elet) system, or a subsequent evolved communication system.

Fig. 1 is a block 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: it should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present invention, and may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop), a personal digital assistant (personal digital assistant, PDA for short), a mobile internet Device (Mobile Internet Device, MID) or a Wearable Device (Wearable Device). 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 evolution communication system, etc., which should be noted that the specific type of the network side device 12 is not limited in the embodiment of the present invention.

Before the technical scheme of the embodiment of the invention is described in detail, a Multi-PUSCH scheduling mechanism is briefly described.

In future communication systems, unlicensed bands (Unlicensed bands) may be used to expand services in addition to Licensed bands (Licensed bands). Since unlicensed bands are shared by multiple technologies (Radio Access Technology, RATs), e.g., wi-Fi, radar, LTE (Long Term Evolution ) based Licensed spectrum Assisted Access to unlicensed spectrum (LTE-LAA), etc. Thus, unlicensed bands must follow certain rules when used to ensure that all devices can share the resource fairly, such as listen-before-transmit channels (Listen Before Talk, LBT), maximum channel occupancy time (Maximum Channel Occupancy Time, MCOT), etc. When the transmission node needs to send information, it is required to execute LBT on the designated wireless channel, perform Energy Detection (ED) on the surrounding wireless transmission environment, and when the Energy is lower than a certain threshold, the channel is judged to be idle, and then the transmission can be started, and the occupied channel time after the transmission node starts to transmit cannot exceed MCOT. The transmission node may be a network-side device, a terminal, a Wi-Fi AP, etc.

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

The concept of Multiple PUSCH Subframe scheduling similar to that in LTE-LAA was also introduced in the standard push procedure of NR-U. Subframes may also be replaced by slots or Mini-slots based on the flexibility of NR in time domain resource allocation. 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 can be used, and the downlink aperiodic CSI reporting mechanism is introduced, namely, the network side equipment can use uplink scheduling DCI to trigger the downlink aperiodic CSI to be transmitted on a scheduled PUSCH according to the requirement, and the terminal can use the scheduled PUSCH to bear the triggered aperiodic CSI. If the corresponding scheme in Multiple PUSCH Subframe scheduling in the LTE-LAA is adopted in NR-U, the following problems will exist:

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

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

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

In summary, in NR-U, when multiple slots or Mini-slots are scheduled by a single DCI, that is, when multiple PUSCHs are scheduled, how to determine which PUSCH or PUSCHs is/are used by a terminal to carry triggered aperiodic CSI, no specific solution is currently given, which results in an unsecured success rate and reliability of reporting the aperiodic CSI, thereby affecting 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 bearing aperiodic CSI.

The terminal may select a target PUSCH from M PUSCHs based on the bearer requirement of the aperiodic CSI, may select a target PUSCH from M PUSCHs according to the indication of the network side device, and may also select a target PUSCH from M PUSCHs based on the terminal LBT condition. Through the comprehensive consideration of the above aspects, the target PUSCH selected by the terminal can meet the load bearing requirement of the aperiodic CSI as far as possible, and the success rate and the reliability of reporting the aperiodic CSI are improved.

Step 204: and the terminal transmits 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 network side equipment, 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 a continuous time domain resource, and a single time domain resource may include one or more PUSCHs. Assuming that the network side device starts from a certain symbol in Slot n+k by using a single DCI scheduling terminal in Slot n, transmitting multiple PUSCHs, each PUSCH corresponding to all or part of the symbols of a single Slot, and there may be 1 or more PUSCHs in a single Slot.

Step 302: and selecting a target PUSCH from the M PUSCHs, wherein the target PUSCH is used for bearing aperiodic CSI.

The target PUSCH may be one PUSCH of the M PUSCHs, may be a plurality of PUSCHs of the M PUSCHs, or may be all PUSCHs of 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 indication of the network side device, and may select from M PUSCHs based on the terminal LBT condition. Regardless of the selection mode, the target PUSCH selected by the terminal can meet the load requirement of the aperiodic CSI as far as possible, so that the success rate and the reliability of reporting the aperiodic CSI are improved, and the performance of the communication system is improved.

The above-mentioned carrying requirement of aperiodic CSI may include at least one of a data amount requirement of aperiodic CSI and a processing time requirement of aperiodic CSI, and thus the above-mentioned target PUSCH may satisfy at least one of a data amount requirement of aperiodic CSI and a processing time requirement of aperiodic CSI. It should be noted that, the target PUSCH selected by the terminal from the M PUSCHs may not meet the data size requirement of the aperiodic CSI, nor meet 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 one or some or all of the PUSCHs are simultaneously used to carry aperiodic CSI; it may not be used to carry transport blocks, i.e. the above-mentioned M PUSCHs are only used to carry aperiodic CSI. Therefore, the data volume of the aperiodic CSI may be required to comprehensively consider the factors such as the data volume carried by the PUSCH, the data volume of the aperiodic CSI, the code rate reduction factor of the aperiodic CSI information, and the like.

The following describes, in detail, various ways of selecting the target PUSCH by the terminal in the embodiment of the present invention, from two aspects that the data amount carried by the M PUSCHs is used to carry the transport block and the aperiodic CSI, and the M PUSCHs are only used to carry the aperiodic CSI, respectively.

First aspect: the M PUSCHs are used to carry transport blocks and aperiodic CSI, i.e., the M PUSCHs are used to carry both aperiodic CSI and transport blocks.

Mode one: and the terminal selects N PUSCHs with the last time from the M PUSCHs as the target PUSCHs, wherein N is an integer greater than or equal to 1.

In this manner, the terminal may fixedly select one or more PUSCHs with the last time position as the target PUSCH for carrying aperiodic CSI.

Since the CSI calculation time or CSI preparation time specified in NR is generally longer than the PUSCH preparation time, one or more PUSCHs, which are positioned earlier in time, among the M PUSCHs described above may not necessarily satisfy the requirement of the CSI calculation time or CSI preparation time. In view of this, in this manner, by fixedly selecting one or more PUSCHs with the rearmost time positions as the target PUSCHs, the target PUSCHs selected by the terminal can be made to meet the processing time requirement of the aperiodic CSI as much as possible, thereby improving the success rate and reliability of the aperiodic CSI reporting. On the data volume requirement of the aperiodic CSI, the network side device can be realized only by ensuring that one or more PUSCHs with the last time position in the scheduled M PUSCHs meet the data volume requirement of the aperiodic CSI during uplink scheduling.

Mode two: and the terminal selects N PUSCHs with the last time from P PUSCHs as the target PUSCHs, wherein the P PUSCHs are PUSCHs meeting at least one of the data volume requirement of the aperiodic CSI and the processing time requirement of the aperiodic CSI, and N is an integer greater than or equal to 1.

In this manner, the terminal may first screen out P PUSCHs satisfying 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 last time from the screened P PUSCHs as the target PUSCH. In this way, 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.

Optionally, the P PUSCHs are PUSCHs meeting the data amount requirement of the aperiodic CSI among the M PUSCHs. That is, the terminal first screens out P PUSCHs satisfying the data amount requirement of the aperiodic CSI from the M PUSCHs, and then selects N PUSCHs with the last time from the screened P PUSCHs as the 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 last 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, thereby further improving the success rate and reliability of reporting the aperiodic CSI.

Mode three: and the terminal selects a target PUSCH from the M PUSCHs according to the indication of the network side equipment.

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

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 triggering state. Each CSI triggering state corresponds to each aperiodic CSI-triggered state and can be configured to the terminal in advance by the network-side device through a CSI triggering state list using higher layer signaling. And when uplink scheduling is performed for a certain time, the network side equipment indicates the specific triggered aperiodic CSI trigger state in the 'CSI request' domain of the DCI.

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

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

If the time domain resource offset is a Slot offset, the reference starting position of the Slot offset may be the Slot where the PDCCH carrying 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 when the time slot corresponding to the time slot offset indicated by the network side equipment only includes a single PUSCH, the terminal directly takes the single PUSCH as a target 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 PUSCH from the plurality of PUSCHs included in the slot as the target PUSCH.

Further, in the case that the time slot corresponding to the time slot offset indicated by the network side device includes a plurality of PUSCHs, the terminal may select, as the target PUSCH, the PUSCH having the largest bearing data amount from the plurality of PUSCHs; alternatively, the terminal may select, as the target PUSCH, a PUSCH which satisfies the data amount requirement of the aperiodic CSI and is the last time from among the plurality of PUSCHs.

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

Mode four: and the terminal selects T PUSCHs from the 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 manner, the terminal selects the target PUSCH according to the LBT condition. And under the condition that the LBT is successful, the terminal selects T PUSCHs from L PUSCHs after the successful access time as target PUSCHs.

In this way, the network side device may determine, by detecting, 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 consistency of the understanding of whether the terminal and the network side device bear the aperiodic CSI on the remaining PUSCH. PUSCH decoding failure may result when the two are inconsistent with the understanding.

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

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

In this scheme, for the former, the terminal selects T PUSCHs as target PUSCHs directly from L PUSCHs actually transmitted after the successful access time. For the latter, the terminal first screens out L PUSCHs which satisfy at least one of the data amount requirement of the aperiodic CSI and the processing time requirement of the aperiodic CSI and are actually transmitted 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 above screening, so that the success rate and reliability of aperiodic CSI reporting can be effectively improved.

Mode five: and the terminal selects all the PUSCHs from the L PUSCHs after the successful access time as the target PUSCHs.

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

In this scheme, for the former, the terminal selects all PUSCHs as target PUSCHs directly from L PUSCHs actually transmitted after the successful access time. For the latter, the terminal firstly screens out L PUSCHs which satisfy at least one of the data amount requirement of the aperiodic CSI and the processing time requirement of the aperiodic CSI and are actually transmitted 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 screened by the above method can better meet the load-bearing requirement of the aperiodic CSI, thereby effectively improving the success rate and reliability of reporting the aperiodic CSI.

In this way, the terminal selects all PUSCHs from the L PUSCHs after the successful access time as the target PUSCH, so that the transmission reliability of the aperiodic CSI can be ensured, and the problem that the resource mapping understanding of the terminal and the network side equipment on the PUSCHs is inconsistent can be avoided.

Second aspect: the M PUSCHs are only used to carry aperiodic CSI, i.e., the M PUSCHs are used to carry aperiodic CSI and are not used to carry transport blocks. The network side device can indicate M PUSCHs capable of meeting the aperiodic CSI data quantity requirement and the aperiodic CSI processing time requirement through DCI.

Mode one: and the terminal selects Y PUSCHs from the K PUSCHs actually transmitted after the successful access time as the target PUSCHs.

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

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

In this way, the network side device may determine K PUSCHs actually transmitted after the terminal successfully accesses the moment through detection, then select Y PUSCHs from the K PUSCHs, and receive the carried aperiodic CSI 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 consistency of the understanding of whether the terminal and the network side device bear the aperiodic CSI on the remaining PUSCH. PUSCH decoding failure may result when the two are inconsistent with the understanding.

The Y PUSCHs (i.e., target PUSCHs) may be the first Y PUSCHs among the K PUSCHs. For example, the target PUSCH may be the first PUSCH of the K PUSCHs, or may be the first plurality of PUSCHs of the K PUSCHs. Where Y is the minimum of the number of protocol specifications (or higher layer configurations) and the number of PUSCHs that are successfully accessed and meet the above requirements.

Mode two: and the terminal selects all the PUSCHs from the K PUSCHs actually transmitted after the successful access time as the target PUSCHs.

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

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

In summary, in the above embodiments, in selecting the target PUSCH, the terminal may comprehensively consider the aspect of the load requirement of the aperiodic CSI, the indication of the network side device, the LBT condition of the terminal, etc., so that the target PUSCH selected by the terminal may meet the load requirement of the aperiodic CSI as much as possible, thereby improving the success rate and reliability of reporting the aperiodic CSI, and further improving the performance of the communication system.

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: transmitting 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: and receiving aperiodic Channel State Information (CSI) on a target PUSCH, wherein the M PUSCHs comprise the target PUSCH.

Optionally, the target PUSCH satisfies at least one of a data amount requirement of the aperiodic CSI and a processing time requirement of the aperiodic CSI.
