Description

Channel transmission method, device and readable storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a channel transmission method, a device, and a readable storage medium.

Background

In the fifth generation new wireless system (5G NR for short, in english: 5Generation New RAT), uplink channel transmission with different physical layer priorities is supported, and one Terminal (also called UE for short, in english: terminal/User Equipment for short, UE) may support different service types, such as enhanced mobile broadband (enhanced Mobile Broadband for short, eMBB) service, low latency high reliability communication (Ultra-Reliable and Low Latency Communication for short, URLLC) service, and the like.

Wherein different traffic types differ in their requirements for reliability and transmission delay. For example, URLLC traffic flows may occur sporadically, thus reserving different system resources independently for different traffic. Due to the relatively large overhead on system resources, resources reserved for URLLC may be unused for many times. In order to improve the utilization rate of system resources, different services can be supported to multiplex transmission on the same resources. However, there may be a resource conflict between uplink channels with different physical layer priorities of the same UE, such as overlapping between symbols occupied by uplink channels with different priorities on the same carrier. In order to avoid the problem that the peak-to-average power ratio (Peak to Average Power Ratio, abbreviated as PAPR) is increased and the power is limited due to the parallel transmission of a plurality of uplink channels at the same time on the same carrier, only a channel with high priority is selected according to the priority when a physical uplink control channel (Physical Uplink Control Channel, abbreviated as PUCCH) collides with a physical uplink shared channel (Physical Uplink Shared Channel, abbreviated as PUSCH) or when two PUCCH channels collide, and a channel with low priority is discarded.

However, in the prior art, when there is a collision between a Dynamic Grant (DG) PUSCH (i.e., DG PUSCH or PUSCH having a corresponding PDCCH) and a Configuration Grant (CG) PUSCH (i.e., CG PUSCH), and at least one of DG PUSCH or CG PUSCH collides with a PUCCH carrying Uplink Control Information (UCI) in english Uplink Control Information, UCI), channel transmission cannot be effectively ensured.

Detailed Description

The term "and/or" in this application describes an association relationship of an association object, which means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

For a clear understanding of the technical solutions of the present application, the prior art solutions will be described in detail first. In the prior art, there are at least the following cases: referring to fig. 1, in case 1, if CG PUSCH and DG PUSCH have the same physical layer priority, PUCCH and PUSCH have the same physical layer priority, and medium access control (english: medium Access Control, abbreviated: MAC) does not open a Logical CHannel (LCH) priority selection rule. According to the multiplexing rule of the PUCCH and the CG PUSCH, the UE does not see that a subsequent DG overlaps with the CG at the time t1 (because the UL grant is relatively late), the UE decides not to prepare UCI transmission on the PUCCH at the time t1 and transfers UCI to the CG PUSCH for transmission, and the result of MAC execution on the CG and the DG is to send protocol data units (English: protocol Data Unit, PDU) (not later than the time t 3) of the DG, but the UE can know whether the PDU of the CG exists at the time t2, because the time t2 is later than t1, when the UE knows that the CG cannot be transmitted, the UCI preparation on the PUCCH cannot be completed before the original PUCCH is sent (including original sequence generation, encoding, scrambling, modulation, mapping and the like), so that UCI cannot be transmitted along with the fact that the CG is not transmitted.

Case 2: if CG PUSCH and DG PUSCH have different physical layer priorities, e.g., DG is high priority, PUCCH has the same physical layer priority as CG PUSCH and is low priority, and MAC does not turn on LCH priority selection rules. The MAC may choose to send PDUs to the channel with a high physical layer priority, i.e. send PDUs to the DG at a time not later than t3, and similarly, the PUCCH with a low priority may determine UCI to be multiplexed onto the PUSCH with the CG with a low priority at a time t1, which also results in that transmission of the UCI with a low priority cannot be achieved when it is determined that the CG has no PDUs at a time t 2.

Case 3: if CG and DG PUSCH have the same physical layer priority, PUCCH and PUSCH also have the same physical layer priority, and MAC turns on LCH priority selection rule, MAC may select one downlink PDU in CG and DG according to their corresponding LCH priority, and DG may be selected. The above-described problems are also present.

Case 4: if CG PUSCH and DG PUSCH have different physical layer priorities, PUCCH and CG PUSCH have the same physical layer priority, and MAC turns on LCH priority selection rules, MAC may select one downlink PDU in CG and DG according to their corresponding LCH priorities, and DG may be selected. The above-described problems are also present.

In addition, when the CG is shifted from the DG, as shown in fig. 2, in cases 3 and 4, there is a problem that UCI cannot be transmitted when the MAC selects to transmit PDU to the CG, and UCI cannot be transmitted.

Therefore, when there is a conflict between DG PUSCH (i.e., first type PUSCH) and CG PUSCH (i.e., second type), and there is a conflict between DG PUSCH or CG PUSCH and PUCCH carrying UCI, no explicit solution is available yet, that is, channel transmission cannot be effectively guaranteed.

The inventor further studies and found that, to effectively guarantee channel transmission, a predetermined rule is required, and which rule or which combination of rules is used to implement channel transmission can be determined according to different judging conditions, namely, UCI is transferred to PUSCH or UCI is transmitted on PUCCH according to one or a combination of rules 1-3.

Based on the inventive study of the above inventor, a channel transmission method proposed in the present application is proposed, in the present application, when there is a collision between DG PUSCH (i.e. first type PUSCH) and CG PUSCH (i.e. second type PUSCH), and at least one of DG PUSCH and CG PUSCH collides with PUCCH carrying UCI, according to rule 1: determining a first target PUSCH carrying the UCI in PUSCHs which conflict with the PUCCH in the first type of PUSCHs and the second type of PUSCHs, and transmitting the UCI on the first target PUSCH, wherein the first target PUSCH is assumed to always have TB transmission; or according to rule 2: determining a first target PUSCH carrying UCI in PUSCHs which have conflict with the PUCCH in the first type of PUSCH and the second type of PUSCH, and determining whether the UCI is transferred to the PUSCH for transmission or the UCI is transmitted on the PUCCH according to the type of the first target PUSCH; or according to rule 3: determining whether the UCI is transferred to the PUSCH to be transmitted or the UCI is transmitted on the PUCCH according to whether the PUSCHs in the first type of PUSCH and the second type of PUSCH acquire the TB; or according to the combination in the rules 1-3, determining that the UCI is transferred to the PUSCH for transmission or the UCI is transmitted on the PUCCH, so that the channel transmission can be effectively ensured under the scene of conflict.

Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 3 is a flow chart of a channel transmission method provided in an embodiment of the present application, and as shown in fig. 3, an execution body of the channel transmission method provided in the embodiment of the present application is a terminal device, where the channel transmission method provided in the embodiment of the present application includes the following steps:

step 101, judging whether a conflict exists between a first type PUSCH and a second type PUSCH, and whether a conflict exists between at least one of the first type PUSCH and the second type PUSCH and a PUCCH carrying UCI;

step 102, when there is a collision between the first type PUSCH and the second type PUSCH and at least one of the first type PUSCH and the second type PUSCH collides with the PUCCH carrying UCI, determining that the UCI is transferred to PUSCH or the UCI is transmitted on PUCCH according to one or a combination of rules 1-3.

Wherein, the first type of PUSCH is PUSCH with a corresponding PDCCH, and the second type of PUSCH is CG PUSCH.

In this embodiment, for the time domain overlap in the presence of a collision (i.e., a collision between PUSCH, which is a collision between PUSCH of the first type and PUSCH of the second type, at least one of PUSCH of the first type and PUSCH of the second type, and PUCCH of the UCI bearing PUCCH, which is a collision between PUCCH and PUSCH, may include at least two cases, case 10: there is an overlap in the time domain on the same carrier, case 20: the time interval between two channels (i.e., between the end symbol of the first channel and the start symbol of the second channel) is less than a predetermined threshold (this is to cover the case of high frequency transmission, where one of the two channels is high frequency and one is low frequency, a certain time interval is required to be maintained in the time domain for adjusting the radio frequency device even if there is no overlap in the time domain, so this process is equivalent to the time domain overlap).

Specifically, rule 1: and determining a first target PUSCH carrying the UCI in the PUSCHs which conflict with the PUCCH in the first type of PUSCHs and the second type of PUSCHs, and transmitting the UCI on the first target PUSCH, wherein the first target PUSCH is assumed to always have TB transmission.

That is, when there is a collision between the first type PUSCH and the second type PUSCH and at least one of the first type PUSCH and the second type PUSCH collides with the PUCCH carrying UCI, a first target PUSCH carrying UCI is determined among PUSCHs of the first type PUSCH and the second type PUSCH that collide with the PUCCH, the UCI is transmitted on the first target PUSCH, wherein it is assumed that the first target PUSCH always has TB transmission.

In this embodiment, when the first target PUSCH in rule 1 is a DG PUSCH, it is assumed that the first target PUSCH always has a TB (i.e., transport Block, english: transport Block) or an uplink shared channel (abbreviated as UL-SCH) transmission, that is, when the UCI is transmitted on the first target PUSCH, a TB or UL-SCH corresponding to the first target PUSCH is also transmitted, which specifically includes:

the MAC always sends PDU to the first target PUSCH;

when the first target PUSCH is configured with UL skip (i.e., UL skip), if the first target PUSCH does not have corresponding data transmission, the MAC will always send a PDU (e.g., a placeholder PDU) to the first target PUSCH;

the PUSCHs other than the first target PUSCH in DG and CG are not transmitted, i.e. the terminal (i.e. the terminal device) does not expect to receive PDUs corresponding to the PUSCHs other than the first target PUSCH in DG and CG.

Rule 2: and in the PUSCHs which have conflict with the PUCCH in the first type of PUSCH and the second type of PUSCH, determining a first target PUSCH carrying UCI, and determining whether the UCI is transferred to the PUSCH to be transmitted or the UCI is transmitted on the PUCCH according to the type of the first target PUSCH.

Namely, when the first type of PUSCH and the second type of PUSCH have conflict, and at least one of the first type of PUSCH and the second type of PUSCH has conflict with the PUCCH carrying UCI, determining a first target PUSCH carrying UCI in the PUSCH which has conflict with the PUCCH in the first type of PUSCH and the second type of PUSCH, and determining whether the UCI is transferred to the PUSCH to be transmitted or the UCI is transmitted on the PUCCH according to the type of the first target PUSCH.

Optionally, the rule 2 includes:

In this embodiment, when the first target PUSCH in rule 2 is a DG PUSCH, it is assumed that the first target PUSCH always has TB or uplink shared channel (UL-SCH) transmission, that is, when the UCI is transmitted on the first target PUSCH, the TB or UL-SCH corresponding to the first target PUSCH is also transmitted, which specifically includes: the MAC always sends PDU to the first target PUSCH; when the first target PUSCH is configured with UL skip (i.e., UL skip), if the first target PUSCH does not have corresponding data transmission, the MAC will always send a PDU (e.g., a placeholder PDU) to the first target PUSCH; the PUSCHs other than the first target PUSCH in DG and CG are not transmitted, i.e. the terminal (i.e. the terminal device) does not expect to receive PDUs corresponding to the PUSCHs other than the first target PUSCH in DG and CG. That is, when the first target PUSCH in rule 1 is DG PUSCH, it is assumed that the first target PUSCH always has TB transmission, and the specific content is the same.

For the case where the first target PUSCH in rule 2 is the CG PUSCH, whether or not to transmit a PUSCH other than the first target PUSCH (i.e., the first type PUSCH) depends on whether or not the MAC has transmitted a PDU to the first type PUSCH, and if so, transmits, and if not, does not transmit; the MAC should not send PDUs to the second PUSCH at this time, and the terminal does not expect to receive PDUs (to the physical layer, or TB) corresponding to the first target PUSCH (i.e., the second PUSCH) at this time because the PDUs are sent and not transmitted.

Optionally, the rule 2 includes:

The PDCCH and the DCI are equivalent, but the PDCCH is a specific channel, and the DCI is a format definition on the transmission content of the PDCCH.

In this embodiment, in rule 2, to ensure that the overlap condition (including the overlap between DG and cG and the overlap with UCI) is determined before PUCCH preparation, before MAC makes a decision to reasonably send PDUs for DG PUSCH and cG PUSCH, the overlap condition can be determined in one way: assuming that the DG PUSCH, CG PUSCH and PUCCH satisfy a time condition of multiplexing transmission as a set of overlapping channels (timer, including T1mux and T2 mux), on one hand, the presence of PUSCH overlapping with UCI is obtained before UCI starts preparation on PUCCH, so that UCI preparation on PUCCH is avoided, and on the other hand, preparation can be completed before PUSCH transmission is satisfied for UCI, i.e., timer 1 is satisfied between a first symbol of a channel having an earliest starting symbol among the DG PUSCH, CG PUSCH and PUCCH and PDSCH or SPS PDSCH release corresponding to PUCCH, and timer 2 is satisfied between a first symbol and DCI (or PDCCH) corresponding to PUCCH and PUSCH; alternatively, another way is: providing that the end symbol of the DCI corresponding to the channel with the latest start symbol in the DG PUSCH, CG PUSCH and PUCCH is not later than T time before the channel with the earliest start symbol, where T is a time length (e.g. a specific time, such as ms, or a specific number of symbols) calculated according to a predetermined rule, e.g. T is a value determined in a manner similar to the value of time 2 assuming that there is an overlap between the channel with the latest start symbol and the channel with the earliest start symbol in the DG PUSCH, CG PUSCH and PUCCH, a specific T value may be different from the value of time 2 described above for time 2, depending on parameters of the specific channel, e.g. T may be calculated according to a specific formula based on SCS of the DCI corresponding to the earliest channel and the latest channel, SCS of PDSCH, SPS PDSCH release corresponding to the PUCCH, SCS of the earliest and/or latest channel itself, and processing time capability (processing capability or 2) of the PUSCH corresponding to the carrier where the earliest and/or latest channel is located.

For a set of overlapped PUCCHs and/or PUSCHs, when one of the PUCCHs or PUSCHs has corresponding downlink control information (in english: downlink Control Information, abbreviated as DCI), for example, a hybrid automatic repeat request acknowledgement (in english: hybrid Automatic Repeat request-acklegend, abbreviated as HARQ-ACK) carried by the PUCCH is a HARQ-ACK of a physical downlink shared channel (in english: physical Downlink Shared Channel, abbreviated as PDSCH) having DCI scheduling, or is a DCI indicating release of downlink Semi-persistent scheduling (Semi-Persistent Scheduling, abbreviated as SPS) resources, the DCI of the scheduled PDSCH or the DCI indicating release of the downlink SPS resources is the DCI corresponding to the PUCCH, for example, the DCI scheduling the PUSCH is the DCI corresponding to the PUSCH), based on the first symbol of the initially earliest channel (if the initial is the same, then optionally one channel) in the set of channels, the following timeline needs to be satisfied:

timeline1: the first symbol is not earlier than a symbol including CP starting after T1 time after the last symbol of any PDSCH or SPS PDSCH release requiring HARQ-ACK feedback on PUCCH, i.e. the time interval between the first symbol and the last symbol of any PDSCH or SPS PDSCH release is not less than T1 time, and T1 is related to the processing delay of PDSCH or SPS PDSCH release, and can be calculated according to the formula and related parameters; the purpose of this timeline is to ensure that the acquisition and preparation of the HARQ-ACK can be completed before the transmission of the finally determined channel for transmitting the HARQ-ACK begins.

timeline2: the first symbol is not earlier than the last symbol of any one of the physical downlink control channels (Physical Downlink Control Channel, abbreviated as PDCCH) of the scheduled PDSCH (if any) and PUSCH (if any), and the symbol including CP is started after the T2 time after the last symbol including PDCCH of indication SPS PDSCH release, i.e. the time interval between the first symbol and the last symbol of any one of the above PDCCHs is not less than the T2 time, and T2 is related to the processing delay of PUSCH and can be calculated according to the formula and related parameters. The purpose of the timeline is to ensure that when multiple UCI multiplexing transmissions exist, the multiple UCI can complete acquisition and multiplexing processing of the various UCI before transmission of the target channel for transmitting UCI starts.

That is, when there is a collision between the first type PUSCH and the second type PUSCH and at least one of the first type PUSCH and the second type PUSCH collides with the PUCCH carrying UCI, determining whether the UCI is transferred to PUSCH or the UCI is transmitted on PUCCH according to whether the PUSCH in the first type PUSCH and the second type PUSCH obtains TB.

In this embodiment, it is determined that PUSCH without obtaining a TB is not transmitted, PUSCH with obtaining a TB is transmitted (MAC transmits PDU to only one PUSCH of DG and CG, i.e. the terminal does not expect to receive PDU to both DG and CG, i.e. the terminal does not expect MAC to transmit PDU to both CG and DG).

Optionally, the rule 3 includes:

In this embodiment, in rule 3, the MAC may select according to LCH priorities corresponding to different PUSCHs, and may select to send a PDU to any one of the first and second PUSCHs, but the MAC only sends a PDU to one of the first and second PUSCHs, i.e., the terminal does not expect to receive a PDU for both the first and second PUSCHs, i.e., the terminal does not expect that the MAC will send a PDU for both the first and second PUSCHs.

Specifically, if it is determined that there is no transmission of PUSCH in collision with the PUCCH (i.e., no TB, if there are multiple PUSCHs overlapping the PUCCH, each overlapping PUSCH is determined to be not transmitted), UCI is transmitted on the PUCCH; if it is determined that at least one PUSCH (TB) determined to be transmitted exists among PUSCHs overlapping with the PUCCH in the time domain, one PUSCH (not selected or considered to be selected if only one PUSCH determined to be transmitted) is selected among the PUSCHs determined to be transmitted, and UCI is transferred to the selected one PUSCH for transmission.

In this embodiment, other PUSCHs that do not collide with the PUCCH may determine whether to transmit according to whether to obtain the TB, if the TB is obtained, the TB may be transmitted, and if the TB is not obtained, the TB is not transmitted.

Determining that the UCI is transferred to PUSCH or UCI is transmitted on PUCCH according to any one or combination of rules 1-3.

In this embodiment, on the one hand, channel transmission may be implemented based on any one of the rules 1, 2, and 3; on the other hand, it is also possible to determine which combination of 1-3 is used to realize channel transmission according to different judgment conditions. That is, when there is a collision between the first type PUSCH and the second type PUSCH and at least one of the first type PUSCH and the second type PUSCH collides with the PUCCH carrying UCI, it is determined that the UCI is transferred to PUSCH or the UCI is transmitted on PUCCH according to any one or combination of rules 1-3.

Optionally, determining which of the usage rules 1-3 is used according to a relation between a starting symbol of the PUCCH and a starting symbol of a second target PUSCH, where the second target PUSCH is a PUSCH having a collision with the PUCCH in the first type PUSCH and the second type PUSCH; or alternatively, the process may be performed,

For the description of rule 1, rule 2 and rule 3, reference may be made to the above embodiments, and the description thereof will be omitted.

Wherein the time determined according to the predetermined rule is determined according to one of the following ways: i.e. the moment determined according to the predetermined rule, can be achieved in several ways:

In this embodiment, the time determined according to the predetermined rule is specifically defined as:

when the processing time of the PUCCH (or may also be referred to as a preparation time, related to the PDSCH processing capability of the UE and the parameter configuration of the PUCCH-related transmission) is smaller than the processing time of the second target PUSCH (related to the PUSCH processing capability of the UE and the parameter configuration of the PUSCH-related transmission), the time determined according to the predetermined rule is a time or symbol corresponding to a Ts time before the start symbol of the second target PUSCH (in particular, a symbol closest to the start symbol of the PUSCH satisfies an interval Ts between the start symbol of the PUSCH), where Ts is a difference between the processing time of the second target PUSCH and the processing time of the PUCCH; or alternatively, the process may be performed,

When the processing time of the PUCCH is greater than the processing time of the second target PUSCH, the time determined according to the predetermined rule is a Ts time (or a symbol corresponding to the Ts time) after the start symbol of the second target PUSCH, where Ts is a difference between the processing time of the PUCCH and the processing time of the second target PUSCH.

Scheme 3: the determining which of the usage rules 1-3 is based on the relation between the ending symbol of the PDCCH corresponding to the PUCCH and the starting symbol of the third target PUSCH includes:

In this embodiment, determining how to transmit according to the relation between the end symbol of the DCI corresponding to the PUCCH and the start symbol of the third target PUSCH specifically includes:

when the time interval between the end symbol of the DCI and the start symbol of the third target PUSCH is not shorter than T time (where T time is a predetermined time, which may be referred to as a predetermined time hereinafter), where the predetermined time may be calculated in a similar manner to the above T time, but specific parameters used may be different, resulting in that the calculated value of T may be different. Reusing rule 1 above; otherwise, (i.e., the case where the above condition is not satisfied, i.e., when the time interval between the end symbol of the DCI and the start symbol of the third target PUSCH is shorter than a predetermined time, or when the end symbol of the DCI is later than the first symbol of a predetermined time before the start symbol of the third target PUSCH): the rule 2 or 3 described above is repeated.

Wherein the DCI is DCI of scheduling PDSCH and the PDSCH transmits HARQ-ACK in the PUCCH, or is DCI indicating downlink SPS resource release and the DCI transmits HARQ-ACK in the PUCCH.

Scheme 4: the determining which of the usage rules 1-3 is used according to the time sequence of the PUCCH and the fourth target PUSCH includes:

In this embodiment, determining how to transmit according to the time sequence between the PUCCH and the third target PUSCH specifically includes:

when the PUCCH is earlier than the third target PUSCH (may be a starting symbol or an ending symbol of the PUCCH is earlier than a starting symbol of the third target PUSCH because the two do not overlap), rule 1 or rule 2 is employed; and when the PUCCH is later than the third target PUSCH, adopting rule 3.

Optionally, when there are a plurality of PUSCHs that collide with the PUCCH in the first type PUSCH and the second type PUSCH, one of the PUSCHs is selected as the second target PUSCH in the following manner: selecting the earliest or latest one of the start symbols, wherein if the start symbols of the plurality of PUSCHs are aligned, any one of the start symbols is selected; alternatively, one of the PUSCHs of a certain class of the first class PUSCH and the second class PUSCH is predetermined to be selected in advance.

When there are a plurality of PUSCHs of the first and second types of PUSCHs that do not collide with the PUCCH, one of the PUSCHs is selected as the third target PUSCH in one of the following manners: selecting the earliest or latest one of the start symbols, wherein if the start symbols of the plurality of PUSCHs are aligned, any one of the start symbols is selected; alternatively, one of the PUSCHs of a certain class of the first class PUSCH and the second class PUSCH is predetermined to be selected in advance.

In this embodiment, the second target PUSCH is a PUSCH in the DG PUSCH and the CG PUSCH, where there is a conflict with the PUCCH carrying UCI (for example, there is an overlap in the time domain, where the time domain overlap may refer to the two cases described in the foregoing embodiment, which are not described herein in detail), and specifically includes: and when the number of the PUSCHs which have conflict with the PUCCH carrying UCI in the DG PUSCH and the CG PUSCH is multiple, selecting one of the PUSCHs as a second target PUSCH. I.e. one of the earliest or latest starting symbols can be selected; if the plurality of start symbols are aligned, selecting any one of them; one PUSCH of DG and CG may be selected, for example, DG or CG.

When there are a plurality of PUSCHs in the first type PUSCH and the second type PUSCH that do not collide with the PUCCH, selecting one of them as the third target PUSCH: one of the earliest or latest start symbols may be selected, and if the start symbols of the plurality of PUSCHs are aligned, any one of them is selected; one of the PUSCHs of a certain category of the first category and the second category may also be selected.

Optionally, at least one of the following is further included:

the second type of PUSCH is not a PUSCH carrying only a-CSI or SP-CSI;

LCH priority is configured or not configured.

Wherein, the PUCCH and the PUSCH are in the same or different carriers; DG PUSCH and CG PUSCH have the same or different physical layer priorities; the DG PUSCH is a PUSCH for UL grant indicating that there is a TB or UL-SCH transmission (i.e., the DG PUSCH is not a PUSCH transmitting only a-CSI or SP-CSI). PUCCH has the same (R16) or different (R17) physical layer priority as PUSCH present in the PUCCH-present time domain; determining the PUSCH carrying UCI without considering which PUSCHs are skip, namely taking the PUSCHs which are overlapped with the PUCCH as a group in the transmission resources corresponding to the PUSCHs, and determining the PUSCHs carrying UCI; the UCI is at least one of HARQ-ACK, scheduling request (english: scheduling Request, abbreviated: SR), and channel state information (english: channel State Information, abbreviated: CSI).

In this embodiment, the DG PUSCH is a PUSCH in which UL grant indicates that there is a TB or UL-SCH transmission, i.e. a PUSCH in which there is a TB transmission when scheduled, but does not represent that MAC will necessarily send a PDU to it, because there may be a skip (i.e. a skip), and PUSCH carrying only a-CSI and SP-CSI, there is no TB transmission per se for this PUSCH, and MAC will certainly not send a PDU to it, and there is no PDU in this embodiment.

In at least one of the downstream cases, the above scheme is performed:

CG PUSCH, DG PUSCH and PUCCH have the same physical layer priority, and MAC does not turn on LCH priority selection rules;

CG and DG PUSCH have different physical layer priorities, PUSCH and PUCCH overlapping the PUCCH in the time domain have the same physical layer priorities, and MAC does not turn on LCH priority selection rules;

CG PUSCH, DG PUSCH and PUCCH have the same physical layer priority, and MAC turns on LCH priority selection rules;

CG and DG PUSCH have different physical layer priorities, PUSCH and PUCCH overlapping the PUCCH in the time domain have the same physical layer priority, and MAC turns on LCH priority selection rules.

In the present application, when there is a collision between DG PUSCH and CG PUSCH and at least one of DG PUSCH and CG PUSCH collides with a PUCCH carrying UCI, transmission is performed according to a predetermined rule (scheme 1), or according to a relationship between a start symbol of the PUCCH carrying UCI and a start symbol of a second target PUSCH (scheme 2), or according to a relationship between an end symbol of DCI corresponding to the PUCCH and a start symbol of a third target PUSCH (scheme 3), or according to a front-back order between the PUCCH and the third target PUSCH (scheme 4). The second target PUSCH is a PUSCH of the DG PUSCH and the CG PUSCH, which overlaps the PUCCH in the time domain, and the third target PUSCH is a PUSCH of the earliest one of the DG PUSCH and the CG PUSCH, which does not overlap the PUCCH in the time domain.

By way of example, embodiments of the present application are described below in conjunction with the accompanying drawings:

embodiment one (rule 1, including direct use or case employed in scheme 2; inability to determine whether there are PDUs in the CG will result in UCI discard, so such case (i.e., case) specifies that there are PDUs in the CG always, UCI is transmitted on CG PUSCH, DG PUSCH is not transmitted.)

Referring to fig. 4, fig. 4 is a schematic view of a scenario of a channel transmission method according to an embodiment of the present application. When rule 1 is directly used, or when scheme 2 is used, according to the Ts time before the start time of the PUCCH is earlier than the start time of the CG PUSCH (assuming that the processing time of the PUCCH is smaller than the processing time of the PUSCH at this time, when the processing time of the PUCCH is greater than the processing time of the PUSCH, here earlier than the Ts time after the start time of the CG PUSCH), rule 1 is determined to be used, that is, UCI is transmitted on the CG PUSCH, PUCCH is not transmitted nor DG PUSCH, MAC needs to always send PDU to the CG PUSCH (even if there is no data to be transmitted in the logical channel to which the CG PUSCH corresponds, PDU of the placeholder needs to be generated), where Ts is the difference between the processing time of the CG PUSCH and the processing time of the PUCCH.

The same applies when CG PUSCH and DG PUSCH are exchanged, and when rule 1 is directly used, or when scheme 2 is used, rule 1 is determined according to that the starting time of PUCCH is earlier than the Ts time before the starting time of DG PUSCH, i.e. UCI is transmitted on DG PUSCH, PUCCH is not transmitted, CG PUSCH is not transmitted, MAC needs to always send PDU to DG PUSCH (even if DG PUSCH is configured with UL skip, and no data is to be transmitted in the corresponding logical channel, PDU of occupying bits needs to be generated), where Ts is the difference between the processing time of PUCCH and the processing time of DG PUSCH.

Example two (rule 2 and rule 3)

Referring to fig. 5 and 6, when 2 is directly used, or when scheme 2 is used, according to the fact that the starting time of PUCCH is aligned with the starting time of CG PUSCH, or according to the fact that the starting time of PUCCH is not earlier than Ts time before the starting time of CG PUSCH (assuming that the processing time of PUCCH is less than the processing time of PUSCH at this time, when the processing time of PUCCH is greater than the processing time of PUSCH, here is later than Ts time after the starting time of CG PUSCH), as shown in fig. 7 and 8, where Ts is the difference between the processing time of CG PUSCH and the processing time of PUCCH, when rule 2 or rule 3 is determined to be used:

when rule 2 is used: assuming that CG PUSCH is not transmitted always according to a predetermined rule, it can be judged at time t1 that CG is not transmitted because there is a collision of DG and CG, thereby determining UCI is transmitted on PUCCH, and whether DG is transmitted depends on whether MAC has transmitted PDU to DG, transmitted, not transmitted, as shown in fig. 5 or fig. 7.

Using rule 3: determining how to transmit according to the selection result of the MAC in CG and DG, for example, if the MAC selects DG (PDU is transmitted for DG but not for CG), determining UCI is transmitted on PUCCH, CG PUSCH is not transmitted, DG PUSCH is transmitted, as shown in fig. 4 or fig. 6; for another example, assuming that the MAC selects CG (PDUs are transmitted for CG and not for DG), CG PDUs and UCI are transmitted on CG PUSCH, PUCCH is not transmitted, and DG PUSCH is not transmitted, as shown in fig. 6 or 8.

The CG PUSCH and the DG PUSCH are exchanged, and the same applies, and in a specific scheme, the PUSCH carrying UCI is replaced by DG, which is not described again.

Example three (scheme 3, timeline met)

The DL grant in the figure is the DCI corresponding to the PUCCH, and the overlapping situation is shown in fig. 9. When rule 1 is directly used, or scheme 3 is used, determining that UCI is transmitted on CG PUSCH according to the end symbol of DL grant is not later than T2 time before the start time of DG PUSCH, and always assuming that CG PUSCH has TB transmission, that is, MAC will be sent to CG PUSCH (even if there is no data to be transmitted in the corresponding logical channel, PDU of the placeholder needs to be generated), PUCCH is not transmitted, DG PUSCH is not transmitted, where T2 is a predetermined time length, related parameters (such as SCS, processing capability, transmission symbol length, etc.) related to DL transmission corresponding to PUCCH and PUCCH, etc., and related parameters related to DG PUSCH; because DL grant is early enough, before MAC decides to generate PDU for DG and sends it, it can be determined that CG and UCI overlap, and it is necessary to ensure that CG has PDU, so MAC can decide not to generate PDU for DG and generate PDU for CG, so as to ensure UCI transmission on CG.

The same applies to exchanging CG PUSCH and DG PUSCH, and as a result, UCI is transmitted on DG PUSCH, PUCCH is not transmitted, and CG PUSCH is not transmitted, so that MAC needs to always send PDU to DG PUSCH (even if DG PUSCH is configured with UL skip and no data is to be transmitted in the corresponding logical channel, PDU with occupying bit is required to be generated). If the PUCCH has no corresponding DCI, it is known that SPS HARQ-ACK is always overlapped with CG before DG PDU preparation is performed, and thus the PUCCH can always be processed according to rule 1.

Example four (scheme 3, not satisfying timeline)

The DL grant in the figure is the DCI corresponding to the PUCCH, and the overlapping is as described in fig. 10 or 11. When rule 2 is directly used or scheme 2 is used, determining to use rule 2 or rule 3 according to the fact that the ending symbol of the DL grant is later than the T2 time before the starting moment of the DGPUSCH; the specific processing procedure is similar to the above embodiment, and will not be repeated; for example, for scheme 2-2 (i.e., rule 3), when it is determined that DG has no TB and CG has TB, it may be determined that UCI is transferred to CG for transmission if it is already known which PUSCH has TB before deciding whether to prepare PUCCH, and the transmission result is shown in fig. 10; for example, when it is determined that CG has no TB and DG has TB, it is known which PUSCH has TB before deciding whether to prepare PUCCH, UCI may be determined to be transmitted on PUCCH, TDM transmission between DG PUSCH and PUCCH, and the transmission result is shown in fig. 11.

The same applies to the CG PUSCH and DG PUSCH being exchanged.

Example five (for scheme 4)

Assuming that DG and CG overlap and only CG therein overlaps PUCCH, if rule 1 or rule 2 is directly adopted or when PUCCH is earlier than PUSCH according to scheme 4, rule 1 or rule 2 is determined to be used, and the specific processing procedure is similar to the result of using rule 1 and rule 2 in the above embodiment, for example, as shown in fig. 4 in embodiment one or fig. 5 and fig. 7 in embodiment two, and will not be repeated; if the usage rule 3 is determined when the PUCCH is later than the PUSCH according to scheme 4, the specific processing procedure is similar to the result of using scheme 2-2 in the above embodiment, for example, as in fig. 10 and 11 in embodiment four, and will not be repeated. Whether there is a sufficient interval between the PUCCH and the CG PUSCH has no influence on the processing result of scheme 4, that is, the difference between the PUCCH and the CG PUSCH in fig. 5, 7, 10, and 11 is not paid attention to, and only the PUCCH is paid attention to earlier than the DG PUSCH.

According to the method and the device, when the conflict exists between the DG PUSCH and the CG PUSCH and the conflict exists between at least one of the DG PUSCH and the CG PUSCH and the PUCCH carrying the UCI, according to a preset rule or according to the relation between the starting symbol of the PUCCH and the starting symbol of the second target PUSCH or according to the relation between the ending symbol of the DCI corresponding to the PUCCH and the starting symbol of the third target PUSCH or according to the front-back sequence between the PUCCH and the third target PUSCH, the problem that when the UCI is firstly determined to be transmitted on a certain PUSCH and then the UCI is known to be incapable of being transmitted, the transmission performance and the efficiency of the UCI are improved, and even if the UCI is obtained by a base station is ensured.

Fig. 12 is a flow chart of a channel transmission method according to another embodiment of the present application, and as shown in fig. 12, an execution body of the channel transmission method according to the present embodiment is a base station, and the channel transmission method according to the embodiment of the present application includes the following steps:

step 201, judging whether a conflict exists between a first type PUSCH and a second type PUSCH, and whether a conflict exists between at least one of the first type PUSCH and the second type PUSCH and a PUCCH carrying UCI;

step 202, when there is a collision between the first PUSCH and the second PUSCH and at least one of the first PUSCH and the second PUSCH collides with the PUCCH carrying UCI, determining, according to one or a combination of rules 1-3, to receive the UCI on one of the first PUSCH and the second PUSCH or to receive the UCI on the PUCCH, where the first PUSCH is a PUSCH having a corresponding PDCCH and the second PUSCH is a CG PUSCH.

Specifically, rule 1: and determining a first target PUSCH carrying the UCI in the PUSCHs in the first category and the PUSCHs in the second category, and receiving the UCI on the first target PUSCH, wherein the first target PUSCH is assumed to always have a TB.

That is, when there is a collision between the first type PUSCH and the second type PUSCH and at least one of the first type PUSCH and the second type PUSCH collides with the PUCCH carrying UCI, a first target PUSCH carrying UCI is determined among PUSCHs of the first type PUSCH and the second type PUSCH that collide with the PUCCH, and the UCI is received on the first target PUSCH, wherein it is assumed that the first target PUSCH always has TB.

Rule 2: and in the PUSCHs which have conflict with the PUCCH in the first type of PUSCH and the second type of PUSCH, determining a first target PUSCH carrying UCI, and determining whether the UCI is transferred to the PUSCH to be received or the UCI is received on the PUCCH according to the type of the first target PUSCH.

Namely, when the first type of PUSCH and the second type of PUSCH have conflict, and at least one of the first type of PUSCH and the second type of PUSCH has conflict with the PUCCH carrying UCI, determining a first target PUSCH carrying UCI in the PUSCH which has conflict with the PUCCH in the first type of PUSCH and the second type of PUSCH, and determining that the UCI is transferred to the PUSCH to be received or the UCI is received on the PUCCH according to the type of the first target PUSCH.

Optionally, the rule 2 includes:

The PDCCH and the DCI are equivalent, and the PDCCH is a specific channel, and the DCI is a format definition on the PDCCH reception content.

That is, when there is a collision between the first type PUSCH and the second type PUSCH and at least one of the first type PUSCH and the second type PUSCH collides with the PUCCH carrying UCI, determining whether the UCI is transferred to PUSCH for reception or the UCI is received on PUCCH according to whether the PUSCH in the first type PUSCH and the second type PUSCH obtains TB.

Optionally, the rule 3 includes:

According to the combination of rules 1-3, it is determined to receive the UCI on one PUSCH of the first type PUSCH and the second type PUSCH or to receive the UCI on the PUCCH.

Wherein the PDCCH is a PDCCH scheduling PDSCH and the PDSCH receives HARQ-ACK in the PUCCH, or a PDCCH indicating downlink SPS resource release and the PDCCH receives HARQ-ACK in the PUCCH.

In this embodiment, how to determine which of the usage rules 1-3 can be specified by the following schemes:

It should be noted that, for the base station side, the above-mentioned transmission behavior corresponding to the terminal device side is changed into the receiving behavior, and the specific scheme design is not repeated.

In this embodiment, when rule 1 is adopted (may be that rule 1 is directly adopted in embodiment one, three or five or rule 1 is used in embodiment one, three or five according to the judgment of the positional relationship in scheme 2, 3 or 4, and rule 1 is used is determined), data and UCI are determined to be received on PUSCH overlapping PUCCH, PUCCH is not received, and other PUSCH overlapping PUSCH carrying UCI is not received in a manner consistent with the terminal.

When rule 2 is adopted (may be that rule 2 is directly adopted in embodiment 2 or 4 or 5 or that rule 2 is directly adopted in embodiment 2 or 4 or 5, or that rule 2 is used is determined according to judgment of a position relation in scheme 2 or 3 or 4), which channel is not transmitted in CG and DG is determined according to a predetermined rule consistent with a terminal, so as to determine a receiving behavior consistent with terminal transmission, wherein if PUSCH overlapped with PUCCH is determined not to be transmitted, UCI is received on PUCCH, how to receive is determined on another PUSCH according to whether UL skip function is available, no UL skip (such as DG is not configured), PUSCH is directly received on DG resource, UL skip (such as CG is determined to be available or DG is configured with this function), and detection is required on corresponding resource to determine whether data transmission is available (such as judging whether data transmission is available by detecting DMRS);

when rule 3 is adopted (e.g., rule 3 is used according to the judgment of the positional relationship in schemes 2 or 3 or 4 in examples 2 or 4 or 5), since which of DG and CG is selected for MAC is transmitted, the base station does not know what is the transmission situation to the base station, and can only determine which channel of DG and CG is actually selected by the terminal MAC according to which hypothesis data is received, respectively, as a result of assuming DG is selected or CG is tried to be received, respectively, and if so, the base station can try to detect UCI on PUCCH resources, and if so, determine that the UE does not transmit CG, thereby further receiving on DG resources (whether or not data is detected directly or first according to whether DG is configured).

According to the channel transmission method, when the conflict exists between the DG PUSCH and the CG PUSCH and the conflict exists between at least one of the DG PUSCH and the CG PUSCH and the PUCCH carrying the UCI, according to a preset rule or according to the relation between the starting symbol of the PUCCH and the starting symbol of the second target PUSCH or according to the relation between the ending symbol of the DCI corresponding to the PUCCH and the starting symbol of the third target PUSCH or according to the front-back sequence between the PUCCH and the third target PUSCH, the situation that the UCI is received on a certain PUSCH is avoided, and then the UCI cannot be received when the PUSCH does not have the PDU is known, so that the receiving performance and the efficiency of the UCI are improved, and the base station is ensured to obtain the UCI.
