Description

Information transmission method and device

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, 5 PUCCH formats, that is, NR Physical Uplink Control CHannel (PUCCH) modes (formats) 0, 1, 2, 3, and 4, are defined, where PUCCH formats 0 and 1 may carry 1-2-bit Uplink Control Information (UCI) transmission, and PUCCH formats 2, 3, and 4 may carry UCI transmission with more than 2 bits. 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 SPSHARQ-ACK and/or the SR is 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 of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits 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 comprises the following steps: when an uplink channel carrying CSI is overlapped with other uplink channels in a time domain, determining channel resources for multiplexing transmission, wherein the channel resources for multiplexing transmission are used for transmitting the CSI and information on the other uplink channels; and determining whether to report CSI on the channel resources for multiplexing transmission according to whether the channel resources for multiplexing transmission are in DRX inactive time.

Wherein the content of the first and second substances,

the CSI comprises at least one of periodic CSI and SP-CSI;

the uplink channel comprises at least one of PUCCH and PUSCH.

Determining channel resources for multiplexed transmission according to a multiplexing transmission rule as follows:

for example, when the PUCCH carrying CSI overlaps with the 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 the CSI resource, that is, the channel used for multiplexing transmission 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 for multiplexing transmission of CSI and HARQ _ ACK (i.e., a channel for multiplexing transmission), that is, the channel for multiplexing transmission is a PUCCH newly determined according to the total number of bits of CSI and HARQ-ACK;

for example, 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, a channel for multiplexed transmission is the PUSCH;

for example, the PUSCH carrying the SP-CSI is overlapped 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 channel for multiplexing transmission is the PUSCH carrying the SP-CSI.

Determining whether to report CSI on the channel resources for multiplexing transmission according to whether the channel resources for multiplexing transmission are in DRX inactivity time, specifically including: determining whether to report CSI on the channel resources for multiplex transmission according to whether the specific symbols of the channel resources for multiplex transmission are in DRX inactive time or not; the specific symbol is a starting symbol or a cut-off symbol or any symbol of an uplink channel carrying 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 CSI masking is configured, for a specific symbol n, when a condition of DRX active time is evaluated, for example, according to scheduling signaling or traffic received 4ms before the specific symbol n (including 4ms time), or a MAC CE corresponding to a DRX command, or a MAC CE corresponding to a long DRX command, it is determined that an on duration timer (onDurationTimer) does not run (i.e., is in DRX inactive time), and CSI is not reported on a PUCCH;

when no CSI masking is configured, for a specific symbol n, when all DRX activation time conditions are evaluated, according to scheduling signaling or service received before 4ms (including 4ms time) of the specific symbol n, or MAC CE corresponding to a DRX command or MAC CE corresponding to a long DRX command, judging that an MAC entity is not in activation time (namely in DRX non-activation time), and reporting neither CSI on a PUCCH nor SP-CSI on a PUSCH;

when determining that the CSI is not reported, not transmitting the CSI on the channel resource for multiplexing transmission, and only transmitting information on other uplink channels; or when determining that the CSI is not reported, simultaneously transmitting the CSI and information on the other uplink channels on the channel for multiplexing transmission, 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;

when the CSI is determined to be reported, the CSI and the information on the other uplink channels are simultaneously transmitted on the channel resource for multiplexing transmission;

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 UCI have at least one symbol overlapping in the time domain;

the other PUCCH carrying the UCI may be a PUCCH carrying any one UCI, or a PUCCH resource determined by performing UCI multiplexing transmission by overlapping the other PUCCH carrying the UCI;

the terminal side and the base station side perform judgment according to the process, and for the transmission of information, the sending action at the terminal side corresponds to the receiving action at the base station side.

An illustration of several specific embodiments is given below.

Example 1:

assuming that there is an overlap in the time domain between the PUCCH resource for CSI and one PUCCH resource carrying SPS HARQ-ACK (i.e., HARQ-ACK for SPS PDSCH), then: according to a multiplexing transmission rule (namely that SPS HARQ-ACK and CSI are determined to be multiplexed and transmitted on the PUCCH resource of CSI), the SPSHARQ-ACK and the CSI can be multiplexed and transmitted on the PUCCH resource of the CSI, namely that the channel resource for multiplexing transmission is determined to be the PUCCH resource of the CSI;

judging whether the PUCCH resource is in DRX inactive time according to a starting symbol n of a channel resource (namely the PUCCH resource of the CSI) for multiplexing transmission, thereby determining whether the CSI needs to be reported on the channel resource for multiplexing transmission; that is, according to the information such as scheduling signaling (e.g. DCI), traffic transmission (e.g. PDSCH), MAC CE corresponding to DRX command, MAC CE corresponding to long (long) DRX command, etc. received in the time before 4ms (including 4ms position) of the starting symbol n, the evaluation is performed according to the condition of DRX activation time, for example: judging whether the starting symbol n is in DRX activation time, and when the starting symbol n is judged not to belong to the DRX activation time (if CSI masking is configured, the onDurationTimer cannot run at the moment of determining the starting symbol n, if CSI masking is not configured, the MAC entity cannot be in activation time at the moment of determining the starting symbol n), determining that CSI does not need to be reported, wherein the behavior of not reporting the CSI comprises not measuring the CSI corresponding to the resource and not transmitting the CSI on the resource; for example, in this embodiment, assuming that it is determined that CSI does not need to be reported according to the above-mentioned manner, SPS HARQ-ACK is directly transmitted on the channel resource for multiplexing transmission without transmitting CSI, as shown in fig. 3;

it should be noted that, in the foregoing embodiment, if SPS HARQ-ACK is replaced by SR, or SPS HARQ-ACK and SR exist at the same time, there is overlap with CSI, or when SP-CSI transmitted on PUSCH overlaps with time domain resources of PUCCH carrying HARQ-ACK (at this time, HARQ-ACK may be dynamic HARQ-ACK or SPS HARQ-ACK), the determined resources for multiplexing transmission are all resources of CSI, and the foregoing method is also applicable.

Example 2:

assuming that both the PUCCH resource carrying CSI and a PDSCH carrying dynamic HARQ-ACK (i.e. the PDSCH corresponding to HARQ-ACK transmitted in PUCCH is scheduled by corresponding DCI, where the DCI includes PUCCH resource indication field PRI field, which may indicate PUCCH resource), overlap in time domain, and the starting position of the PUCCH resource carrying dynamic HARQ-ACK is earlier than the PUCCH resource carrying CSI, then:

according to the multiplexing transmission rule, a corresponding PUCCH resource set is determined according to the total bit number of the HARQ-ACK and the CSI, one PUCCH resource in the set is determined according to PUCCH Resource Indication (PRI) in Downlink Control Information (DCI), and the PUCCH resource is used for multiplexing transmission of the HARQ-ACK and the CSI and can be the same as the PUCCH resource of the original dynamic HARQ-ACK or different from the PUCCH resource of the original dynamic HARQ-ACK.

Judging whether the PUCCH resource is in DRX inactive time according to the initial symbol n of the PUCCH resource subjected to multiplexing transmission, thereby determining whether CSI needs to be reported on the PUCCH resource; the specific method is the same as embodiment 1, and is not described again; when it is determined that there is no CSI, transmitting only dynamic HARQ-ACK on the PUCCH resource for multiplexed transmission (since, although it is determined that there is no CSI, there is no need to use the multiplexed transmission resource in principle, but since the PUCCH resource for the original HARQ-ACK may be more advanced, there may not be enough time to prepare for transmitting HARQ-ACK on the original HARQ-ACK resource after determining whether there is CSI), not transmitting CSI, as shown in fig. 4, when it is determined that there is, simultaneously transmitting dynamic HARQ-ACK and CSI on the PUCCH resource for multiplexed transmission;

it should be noted that, in the above embodiment, if there is an overlap between the SR and the CSI, the method for determining the multiplexing transmission resource is the same as the above, but the total number of bits of the CSI, the SR, and the HARQ-ACK needs to be considered at the same time, and the above method is also applicable.

Example 3:

assuming that there is an overlap in the time domain of PUCCH resources for CSI and resources for one PUSCH (without Aperiodic CSI, a-CSI) carrying Aperiodic CSI: transferring the CSI to a PUSCH according to a multiplexing transmission rule to perform multiplexing transmission with data (UL-SCH) on the PUSCH, namely, the channel resource for multiplexing transmission is a PUSCH resource;

judging whether the PUSCH resource is in DRX inactive time according to a starting symbol n of the channel resource (namely the PUSCH resource) of multiplexing transmission, thereby determining whether CSI needs to be reported on the resource; according to the scheduling signaling (such as DCI), service transmission (such as PDSCH), MAC CE corresponding to DRX command, MAC CE corresponding to long DRX command and the like received in the time before 4ms (including 4ms position) of the initial symbol n, evaluating according to the condition of DRX activation time, determining whether the symbol n is in DRX activation time, and when the symbol n is determined not to belong to the DRX activation time (for example, CSI masking is configured, the onduration timer does not run at the moment of determining the symbol n; for example, in this embodiment, assuming that it is determined that CSI does not need to be reported in the above manner, an uplink shared channel (UL-SCH) is directly transmitted on a channel resource for multiplexing transmission, without transmitting CSI, as shown in fig. 5.

It should be noted that, in the above embodiment, if there are HARQ-ACK and SR at the same time and there is time domain resource overlap with PUSCH, the determined resources for multiplexing transmission are all PUSCH resources, and the above method is also applied.

In summary, referring to fig. 6, an information transmission method provided in the embodiment of the present application on a terminal side includes:

s101, when an uplink channel carrying Channel State Information (CSI) is overlapped with other uplink channels in time domain resources, determining channel resources for multiplexing transmission, wherein the channel resources for multiplexing transmission are used for transmitting the CSI and information on the other uplink channels;
