Description

UCI transmission method, UCI transmission device, UCI transmission terminal and UCI transmission base station

Technical Field

The present invention relates to the field of wireless technologies, and in particular, to a UCI transmission method, apparatus, terminal, and base station.

Background

In a 5G NR system, a carrier may contain up to 4 BandWidth parts (BWP), and a terminal will currently only operate on one BWP at a time, which is called active BWP.

The activation of BWP may be triggered by a timer, or may dynamically indicate BWP switching by scheduling a physical downlink shared CHannel (Physical Downlink Shared Channel, PDSCH) or a physical downlink control CHannel (Physical Downlink Control CHannel, PDCCH) of a physical uplink shared CHannel (Physical Uplink Shared Channel, PUSCH), i.e. a DCI used by the PDCCH includes a BWP indication field, which BWP on a scheduled carrier the terminal receives the PDSCH or transmits the PUSCH, the indicated BWP is the activated BWP, when the indicated BWP number is different from the BWP number of the previously received PDSCH or transmitted PUSCH, indicating that the terminal needs to perform BWP switching, i.e. the terminal needs to receive the PDSCH or transmit the PUSCH on the new BWP indicated by the DCI, and starts to operate on the new BWP after the PDSCH or PUSCH.

The time between the end position of the PDCCH indicating the BWP handover and the start position of the PDSCH or PUSCH scheduled by the PDCCH is referred to as a handover time (transmission time), and is used for a time including PDCCH processing, radio frequency adjustment, preparation of uplink data (for PUSCH transmission), and the like. During the transmission time, the UE does not perform any data reception and transmission on the carrier on which BWP handover is performed.

In the prior art, when BWP switching occurs, if the transmission time of the physical uplink control channel (Physical Uplink Control Channel, PUCCH) carrying uplink control information (Uplink Control Information, UCI) is within the BWP switching time, and there is a PUSCH overlapping with the PUCCH in the time domain on other carriers where no BWP switching occurs, there is no clear method how to perform UCI transmission.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

The UCI transmission method, the terminal and the base station in the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, or an evolved long term evolution (Evolved Long Term Evolution, elet) system, or a subsequent evolved communication system. Referring to fig. 1, a schematic architecture diagram of a wireless communication system to which the transmission method is applied is provided in an embodiment of the present invention. As shown in fig. 1, the wireless communication system may include: base station 10 and terminal 11, terminal 11 may be connected to base station 10. In practical application, the connection between the devices may be wireless connection, and for convenience and intuitionistic representation of the connection relationship between the devices, a solid line is used for illustration in fig. 1.

It should be noted that the communication system may include a plurality of terminals, and the base station may communicate (transmit signaling or transmit data) with the plurality of terminals.

In the embodiment of the present invention, the base station 10 may be an evolved node b (evolved node base station, eNB), or may be a network side device in a 5G system (for example, a next generation base station (next generation node base station, gNB) or a transmitting and receiving point (transmission and reception point, TRP)) or a cell or other device.

The terminal provided by the embodiment of the invention can be a mobile phone, a tablet personal computer, a notebook computer, an Ultra-Mobile Personal Computer (UMPC), a netbook or a personal digital assistant (Personal Digital Assistant, PDA) and the like.

Aiming at the problem that when BWP switching occurs, if the transmission time of the PUCCH carrying UCI is within the BWP switching time and there is a PUSCH overlapping with the PUCCH, the transmission manner of UCI is uncertain in the conventional technology in the scene, the embodiment of the present invention provides a UCI transmission method, which is used for providing the UCI transmission method in the above scene, so as to ensure that the terminal and the base station have transmission behaviors consistent with understanding.

As shown in fig. 2, a method for transmitting uplink control information UCI according to an embodiment of the present invention is applied to a terminal, and includes:

S210, when the transmission time of the physical uplink control channel PUCCH carrying UCI is located in the BWP switching time of the bandwidth portion of the carrier where the PUCCH is transmitted and there is a physical uplink shared channel PUSCH overlapping the PUCCH, one of the following transmission modes is adopted:

discarding the UCI;

discarding the PUCCH, and transmitting the UCI on the PUSCH.

The physical uplink shared channel PUSCH overlapping with the PUCCH is present, that is, there is a PUSCH overlapping with the PUCCH in the time domain, for example, there is a symbol overlapping with the PUCCH in the transmission symbols of the PUSCH, or there is an overlap between the transmission time of the PUSCH and the transmission time of the PUCCH, which is the case where the PUCCH overlaps with the PUSCH in the time domain.

In step S210, a transmission manner of discarding the UCI is adopted, that is, a rule that no transmission and no reception are performed in the BWP switching time is executed first, so that it is determined that the PUCCH is not transmitted, so that no further processing of overlapping of the PUCCH and PUSCH is required;

in step S210, the transmission mode of discarding the PUCCH and transmitting the UCI on the PUSCH is adopted, that is, the overlap of the PUCCH and the PUSCH is processed first, the UCI carried on the PUCCH is transferred to the PUSCH, and then the PUCCH is discarded, so that UCI caused by directly discarding the PUCCH is prevented from being discarded.

In step S210, the carrier on which the PUSCH is transmitted is different from the carrier on which the PUCCH is transmitted, that is, the PUSCH overlapping the PUCCH carrying UCI is transmitted on a carrier different from the carrier on which the PUCCH is transmitted.

For example, the carrier where the PUCCH transmission is located is a primary carrier, and the carrier where the PUSCH transmission is located is a secondary carrier; or, the carrier on which the PUCCH is transmitted is one of the designated secondary carriers, and the carrier on which the PUSCH is transmitted is another carrier (which may be the primary carrier or a secondary carrier different from the designated secondary carrier).

In addition, it should be noted that in the embodiment of the present invention, BWP switching does not exist on the carrier wave where the PUSCH transmission is located; or the transmission time of the PUSCH on the carrier is not positioned in BWP switching time on the carrier where the PUSCH is positioned, so that UCI can be effectively ensured to be transmitted on the PUSCH; i.e. the PUSCH overlapping the PUCCH cannot be transmitted because it is in BWP switching time on the carrier on which the PUSCH transmission is located.

In the embodiment of the present invention, the mentioned BWP handover includes at least one of an uplink BWP handover and a downlink BWP handover; for FDD (paired spectrum), uplink BWP handover and downlink BWP handover are indicated by different DCIs, respectively, e.g., downlink BWP handover is indicated by PDCCH scheduling PDSCH, uplink BWP handover is indicated by PDCCH scheduling PUSCH; for TDD (unpaired spectrum), uplink BWP switching and downlink BWP switching occur simultaneously, which may be indicated by the PDCCH scheduling PDSCH or the PDCCH scheduling PUSCH; of course, BWP switching may also be triggered by a timer, i.e. the timer expires automatically switching to the default BWP; the UCI includes at least one of a hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) -acknowledgement ACK, channel state information (Channel State Information, CSI), and a scheduling request (Scheduling Request, SR).

Further optionally, the start point and the end point of the BWP switch time are determined by at least one of the following:

Specifically, the transmission time between the start point and the end point determined by one of the above modes is the BWP switching time. It should be noted that the above-mentioned determination method of the BWP switching time is merely illustrative, and the present invention is not limited thereto.

In one implementation manner of the UCI transmission method according to the embodiment of the present invention, in step S210, the PUCCH is discarded, and the UCI is transmitted on the PUSCH, including:

wherein the setting conditions include:

when the UCI comprises HARQ-ACK and/or the PUSCH has a corresponding physical downlink control channel PDCCH, the PUCCH and the PUSCH accord with a preset time condition.

Based on the above embodiment, when the UCI includes HARQ-ACK and/or the PUSCH has a corresponding physical downlink control channel PDCCH, a preset time condition judgment needs to be performed first, to determine whether the PUCCH and the PUSCH meet a preset time condition; when the preset time condition is met, a transmission mode of discarding the PUCCH and transmitting the UCI on the PUSCH can be further adopted; when the preset time condition is not met, the specific behavior is considered to be error scheduling, and can be realized based on the terminal, namely, the terminal can arbitrarily select how to transmit.

Further, when the UCI includes HARQ-ACK and the PUSCH has a corresponding PDCCH, and neither condition is satisfied, that is, the UCI does not include HARQ-ACK and the PUSCH does not have a corresponding PDCCH, the transmission mode of discarding the PUCCH and transmitting the UCI on the PUSCH may be directly executed without performing a preset time condition determination.

Specifically, the preset time condition includes:

time condition 1-1: the time interval between the start symbol of the earliest one of the overlapping channels (i.e. PUCCH and PUSCH overlapped therewith, wherein PUSCH may be one or more) and the end symbol of any one of the PDSCHs corresponding to HARQ-ACK is not shorter than T _1-1 Time; i.e. the start symbol of the earliest one of the overlapping channels is not earlier than the end symbol of any one of the PDSCHs corresponding to the HARQ-ACK by T _1-1 Time; the PDSCH corresponding to the HARQ-ACK, namely the PDSCH which needs to transmit the HARQ-ACK on the PUCCH; wherein T is _1-1 Can be defined in TS38.213 protocol

Time conditions 1-2: the time interval between the starting symbol of the earliest channel of the overlapped channels and the ending symbol of any one SPS PDSCH release of Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) PDSCH release (release) (i.e. PDCCH indicating downlink SPS release) corresponding to HARQ-ACK is not shorter than T _1-2 Time; i.e. the start symbol of the earliest one of the overlapping channels is not earlier than the end symbol of any one SPS PDSCH release of SPS PDSCH release corresponding to the HARQ-ACK by T _1-2 Time; SPS PDSCH release where HARQ-ACK corresponds, SPS PDSCH release where HARQ-ACK is required to be transmitted on PUCCH, where T _1-2 Can be defined in TS38.213 protocol

Time condition 2-1: if the HARQ-ACK has corresponding PDCCHs (including PDCCH for scheduling PDSCH and PDCCH for indicating downlink SPS release), the PDSCH and the PDCCH for indicating downlink SPS release transmit the HARQ-ACK on the PUCCH, the time interval between the start symbol of the earliest channel in the overlapped channels and the end symbol of any PDCCH in the PDCCH corresponding to the HARQ-ACK is not shorter than T ₂ Time, i.e. the start symbol of the earliest one of the overlapping channels is not earlier than the end symbol of any one of the PDCCHs corresponding to the HARQ-ACK by T ₂ Time; wherein T is ₂ Can be defined in TS38.213 protocol

Time condition 2-2: if there is PUSCH in the overlapped channelThe corresponding PDCCH (i.e. the PUSCHs are scheduled by the PDCCH), the time interval between the start symbol of the earliest one of the overlapping channels and the end symbol of the PDCCH corresponding to any one of the PUSCHs in the overlapping channels being not shorter than T ₂ Time, i.e. T after the start symbol of the earliest channel in the overlapped channels is not earlier than the end symbol of PDCCH corresponding to any PUSCH ₂ Time; wherein T is ₂ Can be defined in TS38.213 protocol

Specifically, when the HARQ-ACK is included in the UCI, a preset time condition decision needs to be made based on at least one of time condition 1-1, time condition 1-2, time condition 2-1, and time condition 2-2, and for which time condition is performed, or several time conditions are specifically performed, depending on whether the usage conditions of the corresponding time conditions can be satisfied.

For example, whether to perform time condition 1-1 or time condition 1-2 or to perform time condition 1-1 and time condition 1-2 is determined according to whether the terminal receives the corresponding PDSCH and SPS PDSCH release. When the corresponding PDSCH is received, time condition 1-1 may be performed; when the corresponding SPS PDSCH release is received, time condition 1-2 may be performed, and if both the corresponding PDSCH and the corresponding SPS PDSCH release are received, time condition 1-1 and time condition 1-2 are performed, respectively.

Specifically, in the case that the UCI includes the HARQ-ACK and the HARQ-ACK has the corresponding PDCCH, the time condition 2-1 may be executed, and if the HARQ-ACK does not have the corresponding PDCCH, the time condition 2-1 does not need to be executed; that is, at this time, no matter whether there is a corresponding PDCCH on the PUSCH, the time condition 2-1 needs to be performed as long as there is a corresponding PDCCH on the HARQ-ACK.

Specifically, under the circumstance that the PUSCH has a corresponding PDCCH, executing the time condition 2-2, and if the PUSCH has no corresponding PDCCH, executing the time condition 2-2 is not needed; that is, at this time, whether UCI includes HARQ-ACK and whether HARQ-ACK has corresponding PDCCH or not, the time condition 2-2 needs to be performed as long as PUSCH has corresponding PDCCH.

Based on the above, when the UCI includes HARQ-ACK and/or the PUSCH has a corresponding physical downlink control channel PDCCH, after the preset time condition determination of the at least one time condition is performed, if it is determined that the determined time condition is satisfied, the PUCCH is discarded, and the UCI is transmitted on the PUSCH, so that the PUCCH and the PUSCH are prevented from being simultaneously transmitted at the same time, and UCI carried on the PUCCH can be transmitted on the PUSCH.

In one implementation manner of the transmission method in the embodiment of the present invention, in step S210, the discarding the PUCCH and transmitting the UCI on the PUSCH includes:

Specifically, when UCI on PUCCH is transferred to PUSCH, if CSI (such as aperiodic CSI (a-CSI), semi-persistent CSI (SP-CSI), etc.) is included on PUSCH and CSI (such as periodic CSI, SP-CSI, etc.) is included in UCI on PUCCH, CSI in UCI on PUCCH is discarded, that is, other information except CSI in UCI is transmitted on PUSCH (that is, any one or combination of HARQ-ACK and SR in UCI is transferred to PUSCH for transmission), or HARQ-ACK carried on PUCCH is transferred to PUSCH for transmission only (that is, SR is not transferred to PUSCH if SR is included in UCI, that is, SR is discarded, and HARQ-ACK in UCI is transferred only).

In one implementation manner of the transmission method according to the embodiment of the present invention, in step S210, when there are at least two PUSCHs overlapping with the PUCCH, the discarding the PUCCH and transmitting the UCI on the PUSCH includes:

discarding the PUCCH, and transmitting the UCI on one of at least two PUSCHs.

Optionally, in this embodiment, when there are at least two PUSCHs overlapping with the PUCCH, the PUSCH transmitting the UCI is determined in at least one of the following manners:

When at least two PUSCHs overlapped with the PUCCH exist, the PUSCH used for transmitting the UCI can be determined through the PUSCH selection rule so as to enable the terminal to be consistent with the base station in understanding the UCI transmission mode.

A specific implementation of the transmission method according to the embodiment of the present invention is illustrated with reference to fig. 3 and 4.

Referring to fig. 3, in this embodiment, the transmission method is applied to a frequency division duplex (Frequency Division Duplexing, FDD) system. In an FDD system, the frequency domain resources of the uplink transmission UL and the downlink transmission DL are independent. For DCI-indicated BWP handover, for FDD, a PDCCH scheduling a physical downlink shared channel PDSCH may be used to inform DL BWP handover, and a PDCCH scheduling a physical uplink shared channel PUSCH may be used to inform UL BWP handover, which are relatively independent, since DL and UL are paired independent spectrums. Whereas for timer triggered BWP switching, i.e. automatic BWP switching is performed when the timer expires, switching from the current BWP to the Default (Default) BWP.

In the embodiment shown in fig. 3, the carrier CC1 is a carrier for transmitting PUCCH, where the carrier CC1 may be a primary carrier or a designated secondary carrier. As shown in fig. 3, there is one PDCCH 3 in slot n+1 of DL BWP1 of carrier CC1, indicating that UL BWP switching is performed on CC1, from BWP1 to BWP2. Wherein, the PDSCH existing before the time slot n+1 (e.g. in the time slot n) needs to perform HARQ-ACK feedback (PDSCH may exist only on a certain carrier, or PDSCH exists on both carrier CC1 and carrier CC1 as in fig. 3), and the transmission time of the PUCCH carrying HARQ-ACK falls in the BWP switching time; in addition, no BWP switch occurs on carrier CC2, and there is PUSCH 2 overlapping with the PUCCH in time.

According to analysis, the above scenario conforms to the present invention, where the transmission time of the PUCCH carrying UCI is located in the BWP switching time of the bandwidth part of the carrier where the PUCCH is transmitted, and there is an application condition of the PUSCH of the physical uplink shared channel overlapping with the PUCCH, so by adopting the transmission method of UCI in the embodiment of the present invention, the terminal may perform UCI transmission in one of the following manners:

mode one: according to the condition that the transmission time of the PUCCH is within the switching time from BWP1 to BWP2, it is determined that the PUCCH carrying the HARQ-ACK is not transmitted. That is, UCI on the PUCCH is discarded, so that no further processing of overlap of PUCCH with PUSCH 2 is required;

mode two: since the PDSCH 1 corresponding to HARQ-ACK is scheduled by PDCCH and PUSCH has corresponding PDCCH, the determination of the preset time condition can be performed first, and whether the time condition is satisfied can be determined; when the above time condition is satisfied, HARQ-ACK may be transferred to PUSCH 2 on carrier CC2, so that HARQ-ACK is transmitted together with data and/or CSI on PUSCH 2, and PUCCH is not transmitted any more, thereby avoiding the problem of dropping UCI on PUCCH because PUCCH falls in BWP switching time;

when the above time conditions are not satisfied, the terminal may be considered as an error scheduling, and then the terminal may select any transmission mode or select any channel not to transmit, and the base station may not expect what kind of transmission the terminal adopts, and may determine the transmission behavior of the terminal by blind detection under various conditions.

Of course, this embodiment may further include a third mode, in which the HARQ-ACK is directly transferred to PUSCH 2 on carrier CC2 for transmission, and PUCCH is discarded without performing the preset time condition determination in the second mode.

In the embodiment shown in fig. 4, the transmission method is applied to a time division duplex (Time Division Duplexing, TDD) system. In a TDD system, frequency domain resources of uplink transmission UL and downlink transmission DL are shared. Since the frequency domain resources of DL and UL are shared, UL BWP is simultaneously switched when DL BWP is switched on one carrier, and vice versa, i.e., both PDCCH scheduling PDSCH and PDCCH scheduling PUSCH may be used to inform BWP switching, and DL BWP and UL BWP are simultaneously switched when switching.

Referring to fig. 4, in this embodiment, there is one PDCCH 3 in slot n+1 of DL/UL BWP1 of carrier CC1, indicating BWP switching on CC1, from BWP1 to BWP2. Wherein, the PDSCH existing before the time slot n+1 (e.g. in the time slot n) needs to perform HARQ-ACK feedback (PDSCH may exist only on a certain carrier, or PDSCH exists on both carrier CC1 and carrier CC1 as in fig. 4), and the transmission time of the PUCCH carrying HARQ-ACK falls in the BWP switching time; in addition, no BWP switch occurs on carrier CC2, and there is PUSCH 2 overlapping with the PUCCH in time.

Therefore, fig. 4 is the same as the implementation scenario of fig. 3, and in this embodiment, the terminal can also perform UCI transmission in one of the modes described in the embodiment shown in fig. 3, which will not be described in detail here.

Note that, the transmission method for UCI transmission in the embodiments of fig. 3 and fig. 4 is also applicable to the case where the partial scenario is replaced with the following scenario:

for example, the same applies when PDSCH requiring feedback HARQ-ACK is replaced with SPS PDSCH release;

the UL BWP switch is replaced by a PDSCH switch, e.g. PDCCH scheduling in CC1 slot n+1 is equally applicable when one PDSCH is transmitted in slot n+3 on DL BWP 2;

the PUCCH carrying HARQ-ACK is replaced by a PUCCH carrying CSI and/or SR, e.g. PDSCH requiring feedback of HARQ-ACK in time slot n+2 is not present in time slot n, but the same applies when PUCCH carrying CSI and/or SR is determined to be present in time slot n+2 according to the configuration period of CSI/SR.

By adopting the UCI transmission method, when BWP switching occurs, under the scene that the transmission time of the PUCCH carrying the UCI is positioned in the BWP switching time and the PUSCH overlapped with the PUCCH exists, the terminal and the base station can be ensured to have transmission behaviors consistent in understanding.

The embodiment of the invention also provides a transmission method of the uplink control information UCI, which is applied to the base station, as shown in fig. 5, and comprises the following steps:

s510, when judging that the transmission time of a Physical Uplink Control Channel (PUCCH) carrying UCI is located in the BWP switching time of a bandwidth part of a carrier wave where the PUCCH is transmitted and a Physical Uplink Shared Channel (PUSCH) overlapped with the PUCCH exists, determining that a terminal adopts one of the following transmission modes:

discarding the UCI;

discarding the PUCCH, and transmitting the UCI on the PUSCH.

When the transmission method of the UCI in the embodiment of the invention is adopted, when BWP switching occurs, under the scene that the transmission moment of the PUCCH carrying the UCI is positioned in BWP switching time and the PUSCH overlapped with the PUCCH exists, the terminal is determined to adopt one of the transmission modes, so that the terminal and the base station are ensured to have transmission behaviors consistent in understanding.

In the step S510, when determining that the terminal discards the UCI, that is, determining that the terminal first performs any rule of sending and receiving in the BWP switching time, so as to determine that the PUCCH is not transmitted, so that no further processing of overlap between the PUCCH and PUSCH is required, that is, the base station does not need to receive the UCI (that is, the UCI is not received on the PUSCH);

When determining that the terminal discards the PUCCH and transmits the UCI on the PUSCH, namely determining that the terminal firstly processes the overlap of the PUCCH and the PUSCH, transferring the UCI to the PUSCH, and discarding the PUCCH, thereby avoiding that the UCI caused by directly discarding the PUCCH is discarded, namely the base station can receive the UCI on the PUSCH and does not receive the PUCCH.
