Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to an information transmission method and apparatus.
Background
In a New Radio (NR) system, NR Physical Uplink Control CHannel (PUCCH) modes (formats) 0, 1, 2, 3, and 4 are defined, wherein PUCCH formats 0 and 1 may carry 1-2 bit Uplink Control Information (UCI) transmission, and PUCCH formats 2, 3, and 4 may carry more than 2 bit UCI transmission. Hybrid automatic repeat request acknowledgement (HARQ-ACK) may use any one of the 5 PUCCH formats. And the terminal selects one of a plurality of PUCCH resource sets which are configured to the terminal in advance according to the bit number of the HARQ-ACK, wherein each PUCCH resource set corresponds to a bit number range.
The periodic Channel State Information (CSI) may be configured to be transmitted using PUCCH format 2 or 3 or 4, and the used PUCCH resource is configured by higher layer signaling. Semi-persistent CSI (SP-CSI) transmission is also supported, which may be transmitted over PUCCH or Physical Uplink Shared Channel (PUSCH). Semi-persistent transmission on PUCCH is activated by a medium access control element (MAC CE).
In the NR version 15(R15) system, when there is an overlap in time domain resources between different UCI, UCI multiplexing transmission is performed according to a certain rule. When a PUCCH carrying Semi-Persistent Scheduling (SPS) HARQ-ACK (namely HARQ-ACK corresponding to SPS PDSCH) and/or a Scheduling Request (SR) is overlapped with a PUCCH carrying CSI, the SPS HARQ-ACK and/or the SR are transferred to PUCCH resources corresponding to the CSI for multiplexing transmission with the CSI. When a PUCCH carrying dynamic (dynamic) HARQ-ACK (namely the HARQ-ACK corresponding to a PDSCH with corresponding DCI scheduling or SPS PDSCH release) is overlapped with a PUCCH carrying CSI, one set is selected from a plurality of configured PUCCH resource sets according to the bit numbers of the HARQ-ACK and the CSI, and one PUCCH resource is determined from the selected PUCCH resource set according to a PUCCH resource indication domain in the DCI for scheduling Physical Downlink Shared Channel (PDSCH) or SPS PDSCH release (release) and is used for carrying the HARQ-ACK and the CSI simultaneously, wherein each PUCCH resource set corresponds to different UCI transmission bit number ranges, and one PUCCH resource set can contain a plurality of PUCCH resources. When the PUCCH carrying the CSI is overlapped with the PUSCH, the CSI is transferred to a PUSCH resource to be multiplexed and transmitted with uplink data (namely an uplink shared channel (UL-SCH)).
When PUSCH (without UL-SCH) carrying SP-CSI is overlapped with HARQ-ACK, the HARQ-ACK is transferred to the PUSCH carrying SP-CSI for transmission; when the PUSCH carrying the SP-CSI overlaps with the SR (or also includes HARQ-ACK), the SP-CSI is discarded. The NR Media Access Control (MAC) layer specifies that, when Discontinuous Reception (DRX) is configured, for power saving purposes, CSI is not transmitted if periodic or semi-persistent CSI transmission occurs in the DRX inactive state. The specific decision rule includes:
when the CSI mask (masking) is configured, for a symbol n, according to scheduling signaling or traffic received 4ms before the symbol n (including 4ms time), or a MAC CE corresponding to a DRX command, or a MAC CE corresponding to a long DRX command, when a condition of all DRX activation times is evaluated, it is determined that an onDurationTimer (onDurationTimer) does not run, and CSI is not transmitted on a PUCCH;
otherwise (namely, no CSI masking is configured), for the symbol n, according to the scheduling signaling or service received before 4ms (including 4ms time) of the symbol n, or the MAC CE corresponding to the DRX command or the MAC CE corresponding to the long DRX command, when the condition of all DRX activation time is evaluated, the MAC entity is judged not to be in the activation time, and CSI is not transmitted on the PUCCH, and SP-CSI is not transmitted on the PUSCH;
that is, for a symbol n, it is determined whether the symbol n is in an inactive state according to a scheduling signaling or traffic received 4ms before the symbol n (including a time of 4 ms), or a MAC CE corresponding to a DRX command, or a MAC CE corresponding to a long DRX command, and if the symbol n is in the inactive state, CSI (including static CSI (P-CSI) and SP-CSI) is not reported on a PUCCH when a CSI mask is not configured, and CSI (including P-CSI and SP-CSI) is not reported on the PUCCH when the CSI mask is configured, or SP-CSI is not reported on a PUSCH.
In summary, in the prior art, when there is time domain resource overlap between CSI and other channels and DRX is configured, it cannot be ensured that CSI transmission understanding is consistent when the CSI is transmitted by the terminal and the network side under the condition of time domain resource overlap, so that correct transmission of information carried in the other uplink channels is affected.

Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence in the embodiments of the present application only represents the sequence of the embodiments, and does not represent the advantages and disadvantages of the technical solutions provided by the embodiments.
In 5G NR, according to the MAC layer specification, for the purpose of power saving, when DRX is configured, if periodic or semi-persistent CSI transmission occurs in a DRX inactive state, CSI is not transmitted. When there is an overlap of CSI with PUCCH and/or PUSCH, there is no clear solution on how to perform UCI multiplexing transmission in conjunction with DRX configuration. The following problems may exist:
problem 1: when a PUCCH transmission resource carrying CSI and a PUCCH carrying other UCI have time domain resource overlap in the time domain, a PUCCH resource is determined to be used for multiplexing transmission of CSI and other UCI, and the determined PUCCH resource may be a resource of CSI itself, may also be a resource of other UCI, and may also be a newly determined PUCCH resource. As shown in fig. 1, the result of determining whether to transmit CSI may be different according to the CSI original resource and the new PUCCH resource for UCI transmission, and at this time, there is no explicit method for how to perform UCI multiplexing transmission. Another case, as shown in fig. 2, even if it is determined that HARQ-ACK is multiplexed for transmission on the resources of CSI, since the original resources of HARQ-ACK may be CSI-advanced, if the terminal has operated on the assumption that HARQ-ACK is transferred to CSI resources for multiplexed transmission before the time when it is determined whether there is CSI according to the DRX configuration, when the terminal determines that there is actually no CSI transmission (i.e., the CSI resources are in the DRX inactive region), the time when HARQ-ACK transmission is prepared on the original resources of HARQ-ACK has been missed, and thus the terminal may not have reached to transmit only HARQ-ACK on the original resources of HARQ-ACK, and there is no explicit method for how UCI multiplexed transmission is performed.
Problem 2: when a PUCCH transmission resource carrying CSI and a PUSCH overlap in a time domain, the CSI is transferred to the PUSCH for transmission, similar to the case of fig. 1, the result of determining whether to transmit CSI according to the CSI original resource and the PUSCH resource may be different, and at this time, there is no clear method for how to perform UCI multiplexing transmission.
Problem 3: when a PUSCH transmission resource bearing SP-CSI and a PUCCH bearing HARQ-ACK are overlapped on a time domain, the HARQ-ACK is transferred to the PUSCH for transmission, similar to the situation of figure 2, if the time when judging whether the CSI exists on the PUSCH is later than the time when the HARQ-ACK is prepared on the HARQ-ACK channel, no clear method exists for UCI multiplexing transmission at the moment.
The core idea of the technical scheme provided by the embodiment of the application is as follows: when the uplink channel carrying the CSI is overlapped with other uplink channels in the time domain, whether CSI reporting exists is determined according to whether the uplink channel carrying the CSI is in the DRX non-activation time.
Wherein,
the CSI comprises at least one of periodic CSI and SP-CSI;
the uplink channel is at least one of PUCCH and PUSCH;
determining whether to report the CSI according to whether an uplink channel carrying the CSI is in DRX (discontinuous reception) inactive time, specifically comprising the following steps: determining whether to report CSI or not according to whether a specific symbol of an uplink channel carrying the CSI is in DRX (discontinuous reception) inactive time or not; the specific symbol is a starting symbol or a cut-off symbol or any symbol of the uplink channel carrying the CSI;
and for the specific symbol, judging that the specific symbol is in DRX non-activation time according to scheduling signaling or service received before the first 4ms time or 4ms time of the specific symbol or media access control unit (MAC CE) corresponding to a DRX command or MAC CE corresponding to a long DRX command, and determining that CSI is not reported on an uplink channel carrying the CSI. Specifically, for example:
when the CSI masking is configured, for the specific symbol n, when a DRX activation time condition is evaluated, determining that the onDurationTimer does not run (that is, a time domain resource of an uplink channel carrying the CSI is in DRX inactivity time) according to a scheduling signaling or service received 4ms before the symbol n (including 4 ms), or a MAC CE corresponding to a DRX command, or a MAC CE corresponding to a long DRX command, and then not reporting the CSI on the PUCCH;
when no CSI masking is configured, for the specific symbol n, when all DRX activation time conditions are evaluated, according to a scheduling signaling or service received before 4ms (including 4ms time) of the symbol n, or an MAC CE corresponding to a DRX command or an MAC CE corresponding to a long DRX command, judging that an MAC entity is not in an activation time (namely, a time domain resource of an uplink channel carrying CSI is in a DRX non-activation time), and not reporting the CSI on a PUCCH, or reporting an SP-CSI on a PUSCH;
when determining not to report the CSI, further executing the following method:
the method comprises the following steps: not transmitting the uplink channel carrying the CSI, and only transmitting the other uplink channels;
method 2A: determining a first uplink channel for simultaneously transmitting the CSI and information carried in other uplink channels according to a multiplexing transmission rule when the uplink channel carrying the CSI is overlapped with other uplink channels in a time domain, wherein the CSI is not transmitted on the first uplink channel, and only the information carried in the other uplink channels is transmitted; specifically, the multiplexing transmission rule for different overlapping situations is as follows:
for example, when a PUCCH carrying CSI overlaps with a PUCCH carrying SR and/or SPS HARQ-ACK, it is determined that both SR and/or SPS HARQ-ACK and CSI perform multiplexing transmission on CSI resources, that is, the first uplink channel is the PUCCH carrying CSI;
for example, when there is an overlap between a PUCCH carrying CSI and a PUCCH carrying HARQ-ACK having corresponding DCI, determining a PUCCH resource set based on the total number of bits of CSI and HARQ _ ACK, and then determining one PUCCH resource in the PUCCH resource set according to a PUCCH resource indication field in the DCI corresponding to HARQ-ACK, as a PUCCH resource (i.e., a first uplink channel) multiplexing transmission of CSI and HARQ _ ACK, where the first uplink channel is a PUCCH newly determined according to the total number of bits of CSI and HARQ-ACK;
for example, if a PUCCH carrying CSI is overlapped with a PUSCH and the PUSCH does not carry a-CSI, it is determined that the CSI is transferred to the PUSCH and multiplexed with data carried on the PUSCH, that is, the first uplink channel is the PUSCH;
for example, when the PUSCH carrying the SP-CSI overlaps with the PUCCH carrying the CSI and/or HARQ-ACK, the UCI carried on the PUCCH is transferred to the PUSCH for transmission, that is, the first uplink channel is the PUSCH carrying the SP-CSI;
method 2B: determining a first uplink channel for simultaneously transmitting the CSI and information carried in other uplink channels according to a multiplexing transmission rule when the uplink channel carrying the CSI is overlapped with other uplink channels in a time domain, and simultaneously transmitting the CSI and the information carried in other uplink channels on the first uplink channel, wherein the CSI is placeholder bit information or CSI obtained by last measurement; that is, the current transmission does not carry out CSI measurement to save power;
the method 3 comprises the following steps: when the other uplink channels are PUCCHs for bearing scheduling request SR and/or hybrid automatic repeat request acknowledgement HARQ-ACK corresponding to semi-persistent scheduling SPS physical downlink shared channel PDSCH, the method 1 is adopted;
the method 4 comprises the following steps: when the starting symbol of the other uplink channel is earlier than the starting symbol of the uplink channel carrying the CSI, adopting the method 2A or the method 2B;
the method 5 comprises the following steps: when the other uplink channel is a PUCCH carrying a Scheduling Request (SR) and/or a HARQ-ACK corresponding to an SPS PDSCH, the method 1 is adopted when the starting symbol of the other uplink channel is not earlier than the starting symbol of the uplink channel carrying CSI, and the method 2A or the method 2B is adopted when the starting symbol of the other uplink channel is earlier than the uplink channel carrying CSI;
the method 6 comprises the following steps: when the starting symbol of the first uplink channel is not earlier than the starting symbol of the uplink channel carrying the CSI, the method 2A is adopted; when the starting symbol of the first uplink channel is earlier than the starting symbol of the uplink channel carrying CSI (at this time, the time when the first uplink channel starts to be prepared may not determine whether there is CSI, and only can be performed as present, and if there is no subsequent determination, CSI bits also need to be occupied), the method 2B is adopted;
when determining to report CSI (i.e. symbol n is not in DRX inactive time, i.e. symbol n is in DRX active time), further adopting one of the following manners to transmit:
mode 1: multiplexing transmission is carried out according to the multiplexing transmission rule of the channel with the overlapped time domain resources;
mode 2: determining a first uplink channel for simultaneously transmitting the CSI and information carried in other uplink channels according to a multiplexing transmission rule when the uplink channel carrying the CSI is overlapped with other uplink channels in a time domain; determining whether to report the CSI on the first uplink channel according to whether the first uplink channel is in the DRX inactive time, wherein the specific determination method is the same as above and is not repeated herein;
when determining that no CSI is reported on the first uplink channel, the method further comprises transmitting using one of the following methods:
method 2-1, not transmitting the CSI on the first uplink channel, and only transmitting information carried in the other uplink channels;
and 2-2, simultaneously transmitting the CSI and information carried in the other uplink channels on the first uplink channel, wherein the CSI is space bit information or CSI obtained through last measurement. The uplink channel carrying the CSI overlaps with other uplink channels in the time domain, and specifically includes one or more of the following cases:
the PUCCH carrying the CSI and the other PUCCH carrying the uplink control information UCI are overlapped by at least one symbol on the time domain;
the PUCCH and PUSCH carrying the CSI are overlapped by at least one symbol in the time domain;
the PUSCH carrying the SP-CSI and other PUCCHs carrying the UCI are overlapped by at least one symbol in the time domain;
the other PUCCH carrying the UCI is a PUCCH carrying one UCI, or a PUCCH determined by UCI multiplexing transmission due to overlapping of time domain resources between the other PUCCH carrying the UCI.
In the embodiment of the present application, both the terminal side and the network side execute the above processes, and the transmission behavior of the terminal side corresponds to the reception behavior on the network side. On a network side, for example, a base station side, an information transmission method provided in an embodiment of the present application includes:
determining that time domain resource overlapping exists between an uplink channel carrying Channel State Information (CSI) and other uplink channels;
and determining whether to receive the CSI by judging whether an uplink channel carrying the CSI is in the discontinuous reception DRX (discontinuous reception) inactive time.
Other aspects of the network side are the same as those of the terminal side, and are not described herein again.
An illustration of several specific embodiments is given below.
Example 1:
assuming that the PUCCH resources carrying the CSI and the PUCCH resources carrying the SPS HARQ-ACK are overlapped on a time domain, and the starting position of the PUCCH resources carrying the SPS HARQ-ACK is later than the starting position of the PUCCH resources carrying the CSI, then:
judging whether the PUCCH resource bearing the CSI is in DRX (discontinuous reception) inactive time or not according to an initial symbol n of the PUCCH resource bearing the CSI, so as to determine whether the CSI needs to be reported on the PUCCH resource bearing the CSI; according to information such as scheduling signaling (such as DCI), service transmission (such as PDSCH), MAC CE corresponding to DRX commands, MAC CE corresponding to long DRX commands and the like received in time before 4ms (including 4ms position) of starting symbols of PUCCH resources bearing CSI, evaluation is carried out according to the condition of DRX activation time, namely whether the starting symbols n are in the DRX activation time is determined, when the starting symbols n do not belong to the DRX activation time is judged (for example, CSI masking is configured, the onDurationTimer can not run at the moment of the starting symbols n, if the CSI masking is not configured, the MAC entity can not be in the activation time at the moment of the starting symbols n, the CSI is determined not to be required to be reported, wherein the behavior of the CSI not required to be reported comprises the steps of not carrying out CSI measurement corresponding to the resources and not transmitting the CSI on the resources; for example, in the present embodiment, it is assumed that CSI is determined to be absent in the above manner:
when method 1 or method 3 is adopted (no matter whether the PUCCH resource of SPS HARQ-ACK is earlier than the PUCCH resource of CSI): it may be directly determined that only SPS HARQ-ACK is prepared for transmission on PUCCH resources carrying SPS HARQ-ACK only, and no CSI is transmitted, as shown in fig. 3; at this time, since the starting time of the SPS HARQ-ACK resource is delayed, when it is determined that there is no CSI report on the CSI-carrying PUCCH according to the starting symbol n, the terminal has enough time to prepare transmission of the SPS HARQ-ACK-carrying PUCCH.
And on the base station side, if a judgment result consistent with that of the terminal side is obtained, only receiving the SPS HARQ-ACK on the PUCCH resource bearing the SPS HARQ-ACK.
When the method 5 is adopted: determining to use the method 1 according to the starting symbol lag of SPS HARQ-ACK, and the specific process is the same as above;
it should be noted that, in the above embodiment, the above method is also applicable if SPS HARQ-ACK is replaced by SR, or SPS HARQ-ACK and SR exist simultaneously, there is time domain resource overlap with CSI, or SPS HARQ-ACK is replaced by PUSCH, or initial symbol alignment of channels of CSI and SPS HARQ-ACK is assumed, or CSI transmitted on PUCCH is replaced by SP-CSI transmitted on PUSCH in all the above combination cases (except the case of replacing SPS HARQ-ACK by PUSCH or SR).
Example 2:
assuming that the PUCCH resources carrying CSI and the PUCCH resources carrying SPS HARQ-ACK are overlapped on a time domain, and the starting time position of the PUCCH resources carrying SPS HARQ-ACK is earlier than that of the PUCCH resources carrying CSI, then:
judging whether the PUCCH resource is in DRX non-activation time or not according to an initial symbol n of the PUCCH resource carrying CSI, so as to determine whether the CSI needs to be reported on the PUCCH resource or not; the concrete method is the same as that of the example 1;
when method 1 or method 3 is adopted (no matter whether the PUCCH resource of SPS HARQ-ACK is earlier than the PUCCH resource of CSI): when determining not to transmit the CSI, only preparing SPS HARQ-ACK only for transmission on PUCCH resources carrying SPS HARQ-ACK, as shown in fig. 4; at this time, although the starting time of the SPS HARQ-ACK resource is relatively early, the preparation time is relatively short because the SPS HARQ-ACK resource is only 1 bit, and it can be assumed that there is enough time for the transmission preparation of the SPS HARQ-ACK always after determining whether there is CSI.
And on the base station side, if a judgment result consistent with that of the terminal side is obtained, only receiving the SPS HARQ-ACK on the PUCCH resource bearing the SPS HARQ-ACK. When the CSI is determined to be transmitted, the CSI and the SPS HARQ-ACK are multiplexed on the PUCCH resource of the CSI for transmission, and the base station receives the CSI in the same way.
When method 2A or method 2B is employed: firstly, according to a multiplexing transmission rule, SPS HARQ-ACK is determined to be multiplexed on a PUCCH resource of CSI for transmission, because the starting point time of the SPS HARQ-ACK resource is before the starting point time of the CSI resource, the situation that the latest HARQ-ACK preparation time is earlier than the moment of determining whether the CSI exists or not when the SPS HARQ-ACK resource is transmitted on the PUCCH bearing the SPS HARQ-ACK can be possible, then before determining whether the CSI exists or not, the SPS HARQ-ACK and the CSI are multiplexed according to the assumption that the CSI exists (the SPS-ACK and the CSI adopt the same PUCCH resource for transmission), if the moment of determining whether the CSI exists or not is reached, the determination result is that the CSI does not exist, and the terminal cannot return to the PUCCH resource of the SPS-ACK for transmission, because the preparation time is insufficient; at this time, it may be determined directly to use one of the methods 2A or 2B; if the method 2A is adopted, because the SPS and the HARQ-ACK are both transmitted on the CSI resource, and the latest preparation time of the information transmitted on the resource is definitely not earlier than the time for determining whether to transmit the CSI if calculated according to the preparation time of the CSI, the information transmitted on the CSI transmission resource can always be prepared according to the determination result of whether to transmit the CSI, that is, if it is determined that there is no CSI, only the SPS HARQ-ACK is transmitted on the CSI time domain resource, as shown in fig. 5, if it is determined that there is CSI, the SPS and the HARQ-ACK are transmitted on the CSI resource at the same time; and the base station receives the X-bit CSI and the 1-bit SPS HARQ-ACK on the PUCCH resource of the CSI according to the same principle of the terminal side when the CSI is determined to exist, and only receives the 1-bit SPS HARQ-ACK on the PUCCH resource of the CSI when the CSI is determined to not exist. If the method 2B is adopted, that is, since it is determined that multiplexing transmission is performed on the CSI resource according to the multiplexing transmission rule, CSI and spharq-ACK are always transmitted, at this time, if it is determined that there is no CSI, placeholder bits (for example, 0 bit) corresponding to the CSI bit number X are generated, as shown in fig. 6, if it is determined that there is CSI, true CSI is generated, and the placeholder bits or the true CSI are transmitted on the CSI PUCCH resource together with SPS HARQ-ACK; and the base station determines to receive the X-bit CSI and the 1-bit SPS HARQ-ACK on the PUCCH resource of the CSI according to the same principle of the terminal side.
When the method 4 or 5 is adopted, the method 2A or the method 2B is determined to be used according to the advance of the PUCCH resources of the SPS HARQ-ACK, so that the specific process is the same as the above;
when the method 6 is adopted, the method 2A is determined to be adopted according to the condition that the multiplexing channel resource (which is the PUCCH resource of the CSI) does not exceed the former CSI resource, so that the specific process is the same as the above;
it should be noted that, in the above embodiment, the above method is also applicable if SPS HARQ-ACK is replaced by SR, or SPS HARQ-ACK and SR exist simultaneously, there is an overlap with CSI, or SPS HARQ-ACK is replaced by PUSCH, or initial symbol alignment of channels of CSI and SPS HARQ-ACK is assumed, or CSI transmitted on PUCCH is replaced by SP-CSI transmitted on PUSCH in all the combination cases (except the case of replacing SPS HARQ-ACK by PUSCH or SR).
Example 3:
assuming that both the PUCCH resource carrying CSI and a PDSCH carrying dynamic HARQ-ACK (i.e. HARQ-ACK transmitted in PUCCH corresponding to PDSCH are scheduled by corresponding DCI, where the DCI includes PUCCH Resource Indication (PRI) field, which may indicate PUCCH resource), overlap in time domain, and the starting position of PUCCH resource carrying dynamic HARQ-ACK is earlier than PUCCH resource carrying CSI, then:
judging whether the PUCCH resource is in DRX non-activation time or not according to an initial symbol n of the PUCCH resource carrying CSI, so as to determine whether the CSI needs to be reported or not on the resource; the concrete method is the same as that of the example 1;
when method 2A or method 2B is employed: according to the multiplexing transmission rule of dynamic HARQ-ACK and CSI, determining a PUCCH resource for multiplexing transmission of CSI and dynamic HARQ-ACK, namely multiplexing transmission is performed according to the assumption that CSI exists, because when the terminal is transmitted on the PUCCH of HARQ-ACK, the latest HARQ-ACK preparation time is earlier than the moment of determining whether CSI exists, before the terminal is determined whether CSI exists, SPS HARQ-ACK and CSI multiplexing transmission is performed according to the assumption that CSI exists, so as to avoid that when the terminal is determined to have no CSI, the terminal cannot return to the PUCCH resource of HARQ-ACK because there is not enough time to perform HARQ-ACK preparation and cannot transmit on the PUCCH resource of HARQ-ACK, specifically, determining a corresponding PUCCH resource set according to the total bit number of HARQ-ACK and CSI, determining one PUCCH resource in the set according to the PRI in the DCI, for multiplexing the PUCCH resource for transmission of HARQ-ACK and CSI, the resource may be the same as the PUCCH resource of the original dynamic HARQ-ACK or may be a different PUCCH resource from the original dynamic HARQ-ACK. If it can be assumed that the multiplexed transmission resource is later than the starting position of the CSI, or the latest time for performing transmission preparation on the multiplexed transmission resource is later than the time for determining whether the CSI is transmitted, actual transmission on the multiplexed transmission resource can be performed always according to the determination result (i.e., whether the CSI is to be transmitted or not can be determined according to the determination result of the CSI in the actual transmission), because there is enough time to start transmission preparation after the determination result of the CSI, that is, the method 2A can be adopted, if it is determined that there is no CSI report, only HARQ-ACK is transmitted on the multiplexed transmission resource, as shown in fig. 7, if it is determined that there is CSI, CSI and HARQ-ACK are transmitted on the multiplexed transmission resource at the same time; and at the base station side, judging whether CSI exists or not in the same way as the terminal, and performing corresponding receiving behavior according to the judgment result. Since the multiplexing transmission resource itself may lead or lag the starting symbol of the PUCCH resource of CSI, if it cannot always be assumed that the multiplexing transmission resource is later than the starting position of CSI, or the latest time for transmission preparation on the multiplexing transmission resource is later than the time for determining whether CSI is transmitted, the terminal may have started preparation for multiplexing transmission of CSI and HARQ-ACK before the determination result, at this time, CSI cannot be removed according to the determination result of whether CSI exists subsequently, at this time, method 2B may be adopted, which always assumes that CSI and HARQ-ACK are multiplexed on the determined multiplexing transmission resource, but if CSI is determined to be absent, CSI information is an occupied bit, as shown in fig. 8, if CSI is determined, CSI information is an actual bit; and the base station judges whether CSI exists in the same way as the terminal and carries out corresponding receiving behavior according to the judgment result.
When the method 4 is adopted, the PUCCH initial position of dynamic HARQ-ACK is earlier than the PUCCH initial position of CSI, and the method 2A or the method 2B is determined to be used, specifically the same as the above;
when the method 6 is adopted, the multiplexing transmission resource may be determined according to the above-mentioned manner, and whether the method 2A or the method 2B is used is determined according to whether the multiplexing transmission resource leads the CSI, for example, if the start symbol of the multiplexing transmission resource does not lead (align or lag) the start symbol of the CSI, the method 2A may be selected to be used, if the start symbol of the multiplexing transmission resource leads the start symbol of the CSI, the method 2B may be selected to be used, and the execution process after the specific method is selected is the same as above;
it should be noted that, in the above process, the above method is also applicable if there is an SR or an overlap of the PUSCH and the CSI at the same time, or the dynamic HARQ-ACK is replaced by the PUSCH, or the initial symbols of the channels of the CSI and the dynamic HARQ-ACK are assumed to be aligned, or in all the combination cases (except the case of replacing the HARQ-ACK by the PUSCH or the SR), the CSI transmitted on the PUCCH is replaced by the SP-CSI transmitted on the PUSCH.
In particular, in the above embodiment 3, if it is determined that there is CSI transmission according to the CSI resource, it is further able to reuse the above-mentioned determination manner of determining whether the symbol is in the DRX inactivity time according to the first symbol of the multiplexed transmission resource determined according to the multiplexing rule to determine whether there is CSI transmission on the symbol, and if it is determined that there is no CSI transmission, only HARQ-ACK is transmitted on the multiplexed transmission resource.
On the terminal side, referring to fig. 9, an information transmission method provided in an embodiment of the present application includes:
s101, determining that time domain resources of an uplink channel carrying CSI are overlapped with other uplink channels;
s102, determining whether to report the CSI by judging whether an uplink channel carrying the CSI is in discontinuous reception DRX inactive time.
By the method, the time domain resource overlapping of an uplink channel carrying Channel State Information (CSI) and other uplink channels is determined; whether the CSI is reported is determined by judging whether the uplink channel carrying the CSI is in discontinuous reception DRX (discontinuous reception) inactive time, so that the terminal and the network side can ensure that the CSI transmission understanding of the uplink channel carrying the CSI is consistent under the condition that time domain resources of the uplink channel carrying the CSI are overlapped with other uplink channels, and the correct transmission of information carried in the other uplink channels is ensured.
Optionally, the CSI is at least one of periodic CSI, semi-persistent CSI (SP-CSI);
the uplink channel is at least one of a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH).
Optionally, determining whether to report the CSI by determining whether an uplink channel carrying the CSI is in the discontinuous reception DRX inactive time includes:
