Description

Information transmission method, terminal and base station
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a terminal, and a base station.
Background
With the development of mobile communication service demand, many organizations such as ITU have started to research New wireless communication systems (5 Generation New RAT, 5G NR) for future mobile communication systems. In the 5G NR system, Semi-Persistent Scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission is supported. When an SPS PDSCH is configured for a terminal, a transmission interval and a scheduling (CS) Cell Radio Network Temporary Identifier (C-RNTI) need to be configured for the SPS PDSCH, and the CS C-RNTI is used to identify a Physical Downlink Control Channel (PDCCH) corresponding to an SPS service, for example, a PDCCH indicating Downlink SPS resource activation, a PDCCH updating SPS PDSCH transmission configuration, a PDCCH scheduling SPS PDSCH retransmission, and the like. When receiving a PDCCH indicating activation of downlink SPS resources, triggering transmission of a corresponding SPS PDSCH, that is, determining a transmission position of a subsequent SPS PDSCH according to a pre-configured transmission interval, a transmission position of the PDCCH indicating activation of downlink SPS resources, and a scheduling timing between the PDCCH and the PDSCH, where information of transmission configuration of the SPS PDSCH, such as Modulation and Coding Scheme (MCS), frequency domain resources, and the like, is notified in the PDCCH indicating activation of downlink SPS resources, a base station transmits the SPS PDSCH on a corresponding time domain position and frequency domain resources, and a terminal receives the SPS PDSCH on the corresponding time domain position and frequency domain resources.
When the terminal receives the SPS PDSCH, the terminal sends hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback information of the SPS PDSCH through a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH) at a corresponding uplink transmission position according to the definition of the HARQ-ACK feedback time sequence so as to inform a base station whether the SPS PDSCH transmission is correctly received. The HARQ-ACK feedback timing may be defined as an interval from a reference slot corresponding to the PDSCH (considering that uplink transmission carrying HARQ-ACK and baseband parameters (numerology) of the PDSCH may be different, for example, subcarrier spacing is different, the reference slot needs to be defined to find one slot boundary corresponding to numerology of uplink transmission carrying HARQ-ACK as a reference point for determining a HARQ-ACK transmission slot) to a slot of PUCCH/PUSCH carrying its HARQ-ACK, and is determined by one HARQ-ACK timing value, which may be indicated by a HARQ-ACK timing indication field in PDCCH activated by downlink SPS resources or pre-configured by higher layer signaling; thus, the SPS PDSCH is transmitted at a specific location according to a specific configuration, and HARQ-ACK feedback is performed at the specific location. And the PUCCH resource for transmitting the HARQ-ACK of the SPS PDSCH is PUCCH format (format)0 or 1 resource pre-configured by high-layer signaling.
The NR system may also be configured with Channel State Information (CSI) transmission, and may determine a time domain transmission position of the CSI according to a pre-configured transmission period and an offset position, and transmit at a fixed position. The CSI transmitted on the PUCCH may be Periodic CSI (P-CSI) or Semi-Persistent CSI (SP-CSI), where the SP-CSI needs to be activated by the PDCCH to start Periodic transmission according to the configured transmission location.
When the transmission time domain position of the HARQ-ACK feedback of the SPS PDSCH is overlapped with the time domain position of CSI transmission, the PUCCH resource for transmitting the HARQ-ACK of the SPS PDSCH is PUCCH format (format)0 or 1 resource pre-configured by high-level signaling, and cannot be used for carrying transmission of more than 2-bit information, so that the HARQ-ACK of the CSI PDSCH and the HARQ-ACK of the SPS PDSCH cannot be simultaneously placed on the PUCCH resource for transmitting the HARQ-ACK of the SPS PDSCH for transmission. There is currently no clear way of how this is transmitted.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings.
The information transmission method of the embodiment of the invention is applied to a terminal, and as shown in fig. 1, the method comprises the following steps:
step 101: when hybrid automatic repeat request acknowledgement (HARQ-ACK) and Channel State Information (CSI) of a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) need to be transmitted simultaneously, one PUCCH resource set is selected from a plurality of pre-configured PUCCH resource sets according to the sum of the number of bits of the HARQ-ACK and the CSI of the SPS PDSCH.
Here, when it is required to simultaneously transmit HARQ-ACK and CSI for HARQ-ACK of PDSCH, the SPS PDSCH is semi-persistently scheduled, the PUCCH carrying the HARQ-ACK of the SPS PDSCH overlaps with the PUCCH carrying the CSI in the time domain, and the higher layer signaling configuration supports simultaneous transmission of HARQ-ACK and CSI.
The PUCCH carrying the HARQ-ACK of the SPS PDSCH and the PUCCH carrying the CSI may overlap in the time domain, completely, for example, the starting symbols are the same, the transmission length is the same, or partially, for example, the starting symbols are different, or the starting symbols are the same, but the transmission length is different.
Here, the HARQ-ACK included in the PUCCH carrying the HARQ-ACK for the SPS PDSCH is only the HARQ-ACK for the SPS PDSCH, that is, the HARQ-ACK for the PDSCH not including the corresponding PDCCH or the PDCCH indicating the release of the downlink SPS resources.
The plurality of PUCCH resource sets are preconfigured for high-level signaling. The CSI may include periodic CSI, semi-persistent CSI, or aperiodic CSI. The SPS PDSCH is an activated SPS PDSCH, i.e., a PDSCH without a corresponding PDCCH.
Step 102: and determining at least one PUCCH resource in the selected PUCCH resource set according to the PUCCH resource finger time domain in the physical downlink control channel PDCCH for indicating the activation of the downlink SPS resources.
In the NR system, for a PDSCH with corresponding PDCCH scheduling, a higher layer signaling may pre-configure multiple PUCCH resource sets, each PUCCH resource set includes 1 or multiple PUCCH resources, different PCUCH resource sets correspond to different Uplink Control Information (UCI) transmission bit number ranges, for example, assuming that 4 PUCCH resource sets are configured, a first PUCCH resource set corresponds to 1 to 2-bit UCI transmission, a second PUCCH resource set corresponds to 3 to N2-bit UCI transmission, a third PUCCH resource set corresponds to N2+1 to N3-bit UCI transmission, and a fourth PUCCH resource set corresponds to N3+1 to N4-bit UCI transmission, where N2, N3, and N4 are predefined or configured values.
Step 103: transmitting HARQ-ACK of the SPS PDSCH and the CSI simultaneously on the determined at least one PUCCH resource.
According to the information transmission method, when the HARQ-ACK and the CSI of the SPS PDSCH are required to be performed simultaneously, one PUCCH resource set is selected from a plurality of pre-configured PUCCH resource sets according to the sum of the number of bits of the HARQ-ACK and the CSI of the SPS PDSCH; determining at least one PUCCH resource in the selected PUCCH resource set according to a PUCCH resource finger time domain in a PDCCH for indicating downlink SPS resource activation; and the information transmission method can ensure that when a plurality of PUCCHs conflict, any UCI is not discarded, a base station is ensured to obtain a plurality of UCIs in time, the UCI transmission efficiency is improved, and the system performance is improved.
Further, when there is a scheduling request SR that needs to be transmitted simultaneously with the HARQ-ACK of the SPS PDSCH and the CSI, the information transmission method further includes:
and selecting one PUCCH resource set from a plurality of pre-configured PUCCH resource sets according to the sum of the number of bits of the HARQ-ACK, the CSI and the SR of the SPS PDSCH.
Here, the SR needs to be transmitted simultaneously with the HARQ-ACK of the SPS PDSCH and the CSI, which means that a PUCCH carrying the SR overlaps with a PUCCH carrying the HARQ-ACK of the SPS PDSCH in a time domain, or the PUCCH carrying the SR overlaps with a PUCCH carrying the CSI in the time domain, or the PUCCH carrying the SR overlaps with the PUCCH carrying the HARQ-ACK of the SPS PDSCH and the PUCCH carrying the CSI in the time domain, respectively; the SR may be SR information configured only for one SR, or SR information configured for multiple SRs, and the specific SR bit number may be

And K is the number of SR configurations which are overlapped with the HARQ-ACK/CSI.
Further, in the embodiment of the present invention, before performing step 101, the method further includes:
firstly, judging whether the high-level signaling is configured to support HARQ-ACK and CSI simultaneous transmission, and executing the steps 101 to 103 when the high-level signaling is configured to support the HARQ-ACK and CSI simultaneous transmission, otherwise, discarding the CSI and only transmitting the HARQ-ACK;
firstly, judging whether a PUCCH carrying the HARQ-ACK of the SPS (physical downlink shared channel) PDSCH is overlapped with a PUCCH carrying CSI in a time domain, if so, executing the step 101 to the step 103, otherwise, not executing the step 101 to the step 103;
the above procedure applies to the case where only HARQ-ACK for SPS PDSCH collides with CSI.
According to the information transmission method, when the HARQ-ACK and the CSI of the SPS PDSCH are required to be performed simultaneously, one PUCCH resource set is selected from a plurality of pre-configured PUCCH resource sets according to the sum of the number of bits of the HARQ-ACK and the CSI of the SPS PDSCH; determining at least one PUCCH resource in the selected PUCCH resource set according to a PUCCH resource finger time domain in a PDCCH for indicating downlink SPS resource activation; and the information transmission method can ensure that when a plurality of PUCCHs conflict, any UCI is not discarded, a base station is ensured to obtain a plurality of UCIs in time, the UCI transmission efficiency is improved, and the system performance is improved.
As shown in fig. 2, an embodiment of the present invention further provides an information transmission method applied to a base station, where the information transmission method includes:
step 201: when hybrid automatic repeat request acknowledgement (HARQ-ACK) and Channel State Information (CSI) of a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) need to be transmitted simultaneously, one PUCCH resource set is selected from a plurality of pre-configured PUCCH resource sets according to the sum of the number of bits of the HARQ-ACK and the CSI of the SPS PDSCH.
Here, when it is required to simultaneously transmit HARQ-ACK and CSI for HARQ-ACK of PDSCH, the SPS PDSCH is semi-persistently scheduled, the PUCCH carrying the HARQ-ACK of the SPS PDSCH overlaps with the PUCCH carrying the CSI in the time domain, and the higher layer signaling configuration supports simultaneous transmission of HARQ-ACK and CSI.
The PUCCH carrying the HARQ-ACK of the SPS PDSCH and the PUCCH carrying the CSI may overlap in the time domain, completely, for example, the starting symbols are the same, the transmission length is the same, or partially, for example, the starting symbols are different, or the starting symbols are the same, but the transmission length is different.
Here, the HARQ-ACK included in the PUCCH carrying the HARQ-ACK of the SPS PDSCH is only the HARQ _ ACK of the SPS PDSCH, that is, the HARQ-ACK of the PDSCH not including the corresponding PDCCH.
The plurality of PUCCH resource sets are preconfigured for high-level signaling. The CSI may include periodic CSI, semi-persistent CSI, or aperiodic CSI. The SPS PDSCH is an activated SPS PDSCH, i.e., a PDSCH without a corresponding PDCCH.
Step 202: and determining at least one PUCCH resource in the selected PUCCH resource set according to the PUCCH resource finger time domain in the physical downlink control channel PDCCH for indicating the activation of the downlink SPS resources.
In the NR system, for a PDSCH with corresponding PDCCH scheduling, a higher layer signaling may pre-configure multiple PUCCH resource sets, each PUCCH resource set includes 1 or multiple PUCCH resources, different PCUCH resource sets correspond to different Uplink Control Information (UCI) transmission bit number ranges, for example, assuming that 4 PUCCH resource sets are configured, a first PUCCH resource set corresponds to 1 to 2-bit UCI transmission, a second PUCCH resource set corresponds to 3 to N2-bit UCI transmission, a third PUCCH resource set corresponds to N2+1 to N3-bit UCI transmission, and a fourth PUCCH resource set corresponds to N3+1 to N4-bit UCI transmission, where N2, N3, and N4 are predefined or configured values.
Step 203: receiving HARQ-ACK of the SPS PDSCH and the CSI simultaneously on the determined at least one PUCCH resource.
And receiving the HARQ-ACK and the CSI of the SPS PDSCH on the determined at least one PUCCH resource simultaneously, so that when a plurality of PUCCHs conflict, any UCI is not discarded, a base station is ensured to obtain a plurality of UCIs in time, the transmission efficiency of the UCI is improved, and the system performance is improved.
Further, when there is a scheduling request SR that needs to be transmitted simultaneously with the HARQ-ACK of the SPS PDSCH and the CSI, the information transmission method further includes:
and selecting one PUCCH resource set from a plurality of pre-configured PUCCH resource sets according to the sum of the number of bits of the HARQ-ACK, the CSI and the SR of the SPS PDSCH.
Here, the SR needs to be transmitted simultaneously with the HARQ-ACK of the SPS PDSCH and the CSI, which means that the PUCCH carrying the SR overlaps the PUCCH carrying the HARQ-ACK of the SPS PDSCH in the time domain, or the PUCCH carrying the SR overlaps the PUCCH carrying the CSI in the time domain, or the PUCCH carrying the SR overlaps the PUCCH carrying the HARQ-ACK of the SPS PDSCH and the PUCCH carrying the CSI in the time domain, respectively.
Further, in the embodiment of the present invention, before performing step 201, the method further includes:
firstly, judging whether the high-level signaling is configured to support the HARQ-ACK and CSI simultaneous transmission, and executing the steps 201 to 203 when the high-level signaling is configured to support the HARQ-ACK and CSI simultaneous transmission, otherwise, discarding the CSI and only transmitting the HARQ-ACK;
firstly, judging whether a PUCCH carrying the HARQ-ACK of the SPS (physical downlink shared channel) PDSCH is overlapped with a PUCCH carrying CSI in a time domain, if so, executing the step 201 to the step 203, otherwise, not executing the step 201 to the step 203;
the above procedure applies to the case where only HARQ-ACK for SPS PDSCH collides with CSI.
According to the information transmission method, when the HARQ-ACK and the CSI of the SPS PDSCH are required to be performed simultaneously, one PUCCH resource set is selected from a plurality of pre-configured PUCCH resource sets according to the sum of the number of bits of the HARQ-ACK and the CSI of the SPS PDSCH; determining at least one PUCCH resource in the selected PUCCH resource set according to a PUCCH resource finger time domain in a PDCCH for indicating downlink SPS resource activation; and receiving the HARQ-ACK and the CSI of the SPS PDSCH on the determined at least one PUCCH resource simultaneously, so that when a plurality of PUCCHs conflict, any UCI is not discarded, a base station is ensured to obtain a plurality of UCIs in time, the transmission efficiency of the UCI is improved, and the system performance is improved.
The information transmission method according to the embodiment of the present invention is described below with reference to specific embodiments.
Assuming that a terminal receives a PDCCH scrambled by using a CS-RNTI in a time slot n +1 of a wireless frame i, determining that the PDCCH is used for indicating the activation of downlink SPS resources, determining that a PDSCH scheduled by the PDCCH is transmitted in the time slot n +2 according to scheduling timing in the PDCCH, and assuming that a transmission period of a pre-configured SPS PDSCH is once 10ms, determining that the time slot n +2 is a transmission opportunity of the SPS PDSCH in each wireless frame starting from the wireless frame i; assuming that the HARQ-ACK timing value of the SPS PDSCH is 6 (which may be notified in a PDCCH indicating activation of the SPS PDSCH or preconfigured by higher layer signaling), assuming that the numerology corresponding to PUCCH and SPS PDSCH transmission is the same, it may be determined that the SPS PDSCH in slot n +2 performs HARQ-ACK feedback in slot n + 8; according to PUCCH resources pre-configured for the SPS PDSCH, time domain and frequency domain resources of a PUCCH for transmitting HARQ-ACK of the SPS PDSCH in a time slot n +8 can be determined; assuming that periodic CSI is also configured in the system, and according to the configuration period and offset of the periodic CSI, CSI feedback is determined to be performed in a time slot n +8 in each wireless frame, and according to the pre-configuration of a high-level signaling, the time domain and frequency domain resources of a PUCCH carrying the CSI in the time slot n +8 can be determined; as shown in fig. 3, the PUCCH carrying the HARQ-ACK of the SPS PDSCH and the PUCCH carrying the CSI overlap in the time domain in slot n +8 in each radio frame, and since the terminal does not support simultaneous transmission of multiple PUCCHs at the same time in the same carrier group, in slot n +8 in radio frames i and i +1, the following operations are performed:
the terminal selects one of a plurality of PUCCH resource sets pre-configured by a high-level signaling according to the sum of the HARQ-ACK feedback bit number and the CSI feedback bit number of the SPS PDSCH, the HARQ-ACK feedback bit number of the SPS PDSCH is assumed to be 1 bit, the CSI bit number is 20 bits, the PUCCH resource set 1 is assumed to correspond to 1-2 bit transmission, the PUCCH resource set 2 corresponds to 3-20 bit transmission, the PUCCH resource set 3 corresponds to 21-50 bit transmission, and the PUCCH resource set 4 corresponds to 51-100 bit transmission, so that the terminal selects the PUCCH resource set 3.
The terminal further determines a specific resource in the PUCCH resource set 3 according to the indication of the PUCCH resource indication field in the PDCCH indicating SPS resource activation received in slot n +1 of the radio frame i, for example, assuming that the PUCCH resource indication field is 3 bits, each different bit state of the 3-bit indication field indicates one of 8 PUCCH resources included in the PUCCH resource set 3, thereby determining one PUCCH resource in the PUCCH resource set 3.
The terminal transmits HARQ-ACK and CSI of the SPS PDSCH on the determined PUCCH resource at the same time; specifically, the number of bits of the HARQ-ACK and CSI for the SPS PDSCH may be determined based on the total number of bits, and the configured coding rate, determining whether the time-frequency domain resources (such as the number of RBs and the number of symbols) contained in the determined PUCCH resources are enough to transmit the total bit number of the HARQ-ACK and the CSI on the premise of not exceeding the configured coding rate, if not enough, the CSI can be considered to be discarded to some extent until HARQ-ACK for transmitting the SPS PDSCH according to the coding rate on the time-frequency domain resource contained in the PUCCH resource and the residual CSI are met, if sufficient, the actual number of RBs within the frequency domain resources (number of RBs) contained in the PUCCH resource can be further determined, the actual number of RBs is less than the number of RBs contained in the PUCCH resource, and the coding rate satisfying HARQ-ACK and CSI transmission does not exceed the configured number of RBs of the coding rate, so that resources are saved.
The base station side determines the PUCCH resources which are actually transmitted according to the same processing mode as the terminal, and receives the HARQ-ACK and CSI of the SPS PDSCH on the determined PUCCH resources, so that two UCIs are obtained simultaneously, the system influence caused by discarding a certain UCI because the terminal does not support the simultaneous transmission of a plurality of PUCCHs is avoided, and the transmission efficiency of the system is improved.
It should be noted that, in the above embodiment, only the PUCCH carrying the HARQ-ACK of the SPS PDSCH and the PUCCH carrying the CSI partially overlap and the starting symbol of the PUCCH carrying the CSI leads the PUCCH carrying the HARQ-ACK of the SPS PDSCH, and the above method is applied to overlap in other cases, for example, complete overlap, that is, the PUCCH carrying the HARQ-ACK of the SPS PDSCH and the PUCCH carrying the CSI have the same time domain symbol position (that is, the starting position and the length are the same) in the same slot, or the PUCCH carrying the HARQ-ACK of the SPS PDSCH and the PUCCH carrying the CSI partially overlap and the starting symbol of the PUCCH carrying the HARQ-ACK of the SPS PDSCH leads the PUCCH carrying the CSI;
the above embodiment only takes the SPS PDSCH and PUCCH having the same numerology as an example, and if having different numerologies only affects the determination of the corresponding HARQ-ACK transmission slot according to the reference slot corresponding to the SPS PDSCH and the HARQ-ACK timing, the end position of the reference slot may not be the end position of the slot where the SPS PDSCH is located, this also applies to the above method;
the above embodiment only takes the overlapping of HARQ-ACK and CSI of SPS PDSCH as an example, and the above manner is also applicable if there is an overlapping of SR and both, and the only difference is that when determining the PUCCH resource set in the first step, the total number of bits of HARQ-ACK, CSI and SR of SPS PDSCH is considered;
the HARQ-ACK timing, scheduling timing, and periodic transmission position in the above embodiments are all examples, and other values or configuration situations are also applicable to the embodiments of the present invention.
The information transmission method of the embodiment of the invention ensures that when a plurality of PUCCHs conflict, any UCI is not discarded, ensures that a base station can obtain a plurality of UCIs, improves the transmission efficiency of the UCI and improves the system performance.
