Description

Method and equipment for sending uplink control information

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for sending uplink control information.

Background

The UCI is a generic term of uplink control information, and includes: an acknowledgement message HARQ-ACK, a scheduling request SR and channel state information CSI. The HARQ-ACK is feedback of the UE on downlink transmission, and when a data packet arrives at the receiving end, error detection is performed on the data packet, and if the data packet is received correctly, an ACK signal is returned, and if the data packet is received incorrectly, a NACK signal is returned. When the UE has no UL-SCH resource, HARQ-ACK is transmitted on a Physical Uplink Control Channel (PUCCH), and when the UE has the UL-SCH resource, the HARQ-ACK is transmitted on the UL-SCH. When the UE does not have UL-SCH resources, the SR is used to request UL-SCH resources from the base station, since the SR is only sent without UL-SCH. Therefore, the SR can only be transmitted on PUCCH. The resource of the PUCCH transmitting the SR is periodic of the system configuration. The CSI including CQI/PMI/RI is the report of the downlink state information by the UE, and may be divided into periodic CSI (periodic CSI, P-CSI), aperiodic CSI (aperiodic CSI, CSI), and Semi-static CSI (Semi-Persistent CSI, SP-CSI) according to the transmission mode. The P-CSI is CSI which is configured by a higher layer and is sent according to a certain period, when no PUSCH is scheduled, the CSI is transmitted on a PUCCH configured by the higher layer, and when a physical uplink shared channel PUSCH is scheduled and the PUCCH and the PUSCH cannot be simultaneously transmitted, the CSI is transmitted on a scheduled PUSCH. For A-CSI, a base station dynamically triggers through downlink signaling and sends the A-CSI on a scheduled PUSCH resource, and the A-CSI is triggered to be sent once. And for SP-CSI, triggering through downlink signaling and sending for multiple times according to a certain period, wherein if the base station is triggered through MAC CE, the SP-CSI is sent on PUCCH resources, and if the base station is triggered through DCI, the SP-CSI is sent on PUSCH.

It can be seen that HARQ-ACK, SR, and CSI (p-CSI and SP-CSI) can be transmitted on PUCCH, where HARQ-ACK is feedback for downlink transmission and is to be determined according to actual downlink transmission, and PUCCH resources are dynamically determined according to radio resource control RRC configuration and downlink scheduling. However, since the CSI and the SR are transmitted periodically, there may be a collision with the dynamically scheduled HARQ-ACK, i.e. they need to be transmitted at the same or partially overlapping time.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.

The technical scheme of the invention can be applied to various communication systems, such as: global System for Mobile communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE)/enhanced Long Term evolution (LTE-a), nr (new Radio), and the like.

A User Equipment (UE), which may also be referred to as a Mobile Terminal (Mobile Terminal), a Mobile User Equipment (UE), a Terminal Equipment, etc., may communicate with one or more core networks via a Radio Access Network (RAN, Radio Access Network, for example), and the User Equipment may be a Mobile Terminal, such as a Mobile phone (or referred to as a "cellular" phone) and a computer having a Mobile Terminal, such as a portable, pocket, handheld, computer-included, or vehicle-mounted Mobile device, which exchanges language and/or data with the Radio Access Network.

PUCCH format refers to the definition of PUCCH in different formats in section 6.3.2.1 of protocol 38.211. It should be noted that the main scenarios of the 5G NR include eMBB, URLLC, and mtc, and these scenarios impose requirements on the system such as high reliability, low delay, large bandwidth, and wide coverage. In order to meet different required services and different application scenarios, NR introduces PUCCHs with different lengths, short PUCCH (1/2 OFDM symbols) and long PUCCH (4-14 OFDM symbols). Meanwhile, according to the size of UCI effective data payload carried by the PUCCH, the UCI is divided into short/long PUCCH with up to2bit UCI and short/long PUCCH with more than 2bit UCI. The long PUCCH with more than 2 bits is divided into the cases of supporting multi-user multiplexing and not supporting multi-user multiplexing. Referring specifically to chapter 6.3.2.1, table 6.3.2.1-1 (hereinafter referred to as table 1),

PUCCH format 2/3/4 is a UCI (including HARQ-ACK, CSI, and SR) that can transmit more than 2 bits, PUCCH format 2 is shortPUCCH occupying 1, 2 OFDM symbols in the time domain, and 1 to multiple PRBs in the frequency domain; the format 3/4 is that long PUCCH occupies 4-14 OFDM symbols in time domain, the frequency domain of PUCCH format 3 can be 1 to multiple PRBs, and multi-user multiplexing is not supported, the frequency domain of PUCCH format 4 only has 1 PRB, and 2/4 users are supported to be multiplexed on the same time-frequency resource.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Example 1

Fig. 1 is a schematic flowchart of a method for sending uplink control information according to embodiment 1 of the present invention, and referring to fig. 1, the method may specifically include the following steps:

step 12, the network side equipment sends configuration information to the terminal equipment;

it should be noted that, the first implementation manner of step 12 may be:

and the network side equipment sends configuration information to the terminal equipment, and the configuration information carries a synchronous transmission instruction.

Wherein the simultaneous transmission indication at least comprises: whether at least one of a PUCCH format transmitting the CSI and a PUCCH format transmitting the HARQ-ACK bits supports HARQ-ACK bits and CSI concurrent transmission. It may specifically be: the network device configures whether a certain PUCCH format supports CSI and HARQ-ACK transmission on one PUCCH by sending higher layer signaling to the mobile terminal device, for example: for PUCCH format 2, if the parameter simultaneousHARQ-ACK-CSI is set to true when PUCCH format 2 is configured, it indicates that PUCCH format 2 supports CSI and HARQ-ACK transmission on one PUCCH. If the parameter simultaneousHARQ-ACK-CSI is set to false, it indicates that PUCCH format 2 does not support CSI and HARQ-ACK transmission on one PUCCH. Similarly, the PUCCH format 3/4 corresponds to whether the corresponding higher layer parameter configuration supports CSI and HARQ-ACK supporting concurrent transmission.

The PUCCH format for transmitting CSI and the PUCCH format for transmitting HARQ-ACK bits may be configured by the network side device. Taking the PUCCH format for transmitting CSI as an example, the following specific examples may be: the network side equipment provides at least one PUCCH resource, each resource determines the format of the PUCCH, and then the terminal equipment selects one PUCCH resource based on a predetermined mode, so that one PUCCH format is determined.

A second implementation of step 12 may be:

and the network side equipment sends configuration information to the terminal equipment, wherein the configuration information carries a simultaneous transmission indication and a PUCCH format for transmitting CSI and a PUCCH format for transmitting HARQ-ACK bits.

Wherein the simultaneous transmission indication at least comprises: whether at least one of a PUCCH format transmitting the CSI and a PUCCH format transmitting the HARQ-ACK bits supports HARQ-ACK bits and CSI concurrent transmission; the PUCCH formats for transmitting CSI and the PUCCH formats for transmitting HARQ-ACK bits are several formats shown in table 1, for example: the PUCCH format for transmitting the CSI is PUCCH format 2, and the PUCCH format for transmitting the HARQ-ACK bits is PUCCH format 0.

A third implementation of step 12 may be:

and the network side equipment sends configuration information to the terminal equipment, the configuration information carries simultaneous transmission indication and the number of feedback scheduling bits, the PUCCH format for transmitting CSI and the PUCCH format for transmitting the feedback scheduling bits, and the transmission of the feedback scheduling bits and the CSI is determined.

Wherein the feedback scheduling bit comprises a HARQ-ACK bit, or a HARQ-ACK bit and an SR; the indication of simultaneous transmission at least comprises: whether at least one of a PUCCH format for transmitting CSI and a PUCCH format for transmitting feedback scheduling bits supports simultaneous transmission of the feedback scheduling bits and the CSI; the PUCCH format for transmitting CSI and the PUCCH format for transmitting feedback scheduling bits may be several formats shown in table 1.

For convenience of subsequent description, it is understood that two feedback scheduling bits including HARQ-ACK bits, or HARQ-ACK bits and SR, may be denoted as HARQ-ACK bits with/with out SR, and of course, PUCCH resources transmitting the feedback scheduling bits may also be denoted as PUCCH resources transmitting the HARQ-ACK bits in the second implementation.

In the three implementation manners of step 12, an implementation manner in which the network side device sends the synchronous transmission instruction to the terminal device may be, for example: and the network side equipment sends a high-level signaling to the terminal equipment, the high-level signaling carries a field simultaneous HARQ-ACK-CSI, and if the value of the field is set to true, the network side equipment indicates that the CSI and the HARQ ACK are simultaneously transmitted on one PUCCH.

And step 14, when the first time domain resource is the same as or overlapped with the second time domain resource, determining the transmission of the HARQ-ACK bit and the CSI according to the Physical Uplink Control Channel (PUCCH) format for transmitting the Channel State Information (CSI) and the PUCCH format for transmitting the hybrid automatic repeat request acknowledgement (HARQ-ACK bit).

It is understood that the CSI and HARQ-ACK may both be carried on PUCCH based on the description in the background art. If the CSI and the HARQ-ACK are required to be transmitted at the same or partially the same time in one slot, i.e. under different conditions of collision, the UE has multiple PUCCH resources, but the UE can only transmit one PUCCH at the same time. Therefore, some collision handling methods need to be adopted, such as: combining, discarding some information, deciding which PUCCH resource to use for transmission, how to transmit UCI (sending only ACK, or sending only CSI, or sending both ACK and CSI), etc. The specific transmission method can be exemplified as follows:

the transmission mode 1, discarding one of the CSI and HARQ-ACK bits, includes:

alt 1: discarding CSI, transmitting HARQ-ACK on PUCCH resources transmitting HARQ-ACK bits

alt 2: discarding ACK, transmitting CSI on PUCCH resource for transmitting CSI

And the transmission mode 2 is used for simultaneously transmitting CSI and HARQ-ACK bits on a PUCCH resource for transmitting the CSI, and comprises the following steps:

alt 1: if the sum of the bit number of ACK + CSI exceeds the maximum code rate, discarding part of CSI by using the priority principle when the same CSI is transmitted on the PUSCH

alt 2: if the sum of the number of bits of ACK + CSI exceeds the maximum code rate, HARQ-ACK Bundling is carried out first, if the sum of the number of bits of the ACK + CSI exceeds the maximum code rate after the HARQ-ACK Bundling, the sum of the number of bits of the HARQ-ACK Bundling and the number of bits of the CSI still exceeds the maximum code rate, and partial CSI is discarded by using the priority principle when the same CSI is transmitted on a PUSCH

And a transmission mode 3 for simultaneously transmitting the CSI and the HARQ-ACK on the PUCCH resource for transmitting the HARQ-ACK bit, wherein the transmission mode comprises the following steps:

A transmission mode 4, selecting one of the more PRBs to transmit the CSI and the HARQ-ACK bit at the same time according to the number of PUCCH resources for transmitting the HARQ-ACK bit and the CSI; if the maximum PRB numbers configured by the two PRBs are the same, the PUCCH resource for transmitting the HARQ-ACK bit is preferentially used, and the method comprises the following steps:

alt 2: and if the sum of the bit numbers of the ACK and the CSI exceeds the maximum code rate, HARQ-ACK Bundling is carried out first, and if the sum of the bit numbers of the ACK and the CSI still exceeds the maximum code rate after the HARQ-ACK Bundling is carried out, part of the CSI is discarded by using a priority principle when the same CSI is transmitted on a PUSCH.

For the transmission modes 2-4, it should be noted that "the priority of CSI transmitted on PUSCH" is written in the protocol and can be queried, and therefore, the details thereof are not repeated here.

Based on the above "collision", how to select the listed transmission modes to complete the transmission of the HARQ-ACK bits and the CSI, a first implementation manner of step 14 may be:

the terminal device finds out a corresponding transmission mode from the transmission mode list based on the simultaneous transmission indication determined in the first two implementation modes in step 12, the PUCCH format for transmitting the CSI, and the PUCCH format for transmitting the HARQ-ACK bit, and transmits at least one of the HARQ-ACK bit and the CSI based on the found transmission mode.

A second implementation of step 14 may be:

first, the terminal device determines the number of feedback scheduling bits, which include HARQ-ACK bits, or HARQ-ACK bits and an SR.

And then, based on the number of the feedback scheduling bits, the simultaneous transmission indication, the PUCCH format for transmitting the CSI and the PUCCH format for transmitting the feedback scheduling bits, finding out a corresponding transmission mode from the transmission mode list, and transmitting the HARQ-ACK bits and the CS based on the found transmission mode.

For the above-listed implementation manner of step 14, the transmission manner list may specifically be as follows 2:

when the sum of the number of bits of the HARQ-ACK bit and the number of bits of the CSI exceeds the maximum code rate, binding the HARQ-ACK bit, if the sum of the number of bits of the bound HARQ-ACK bit and the number of bits of the CSI exceeds the maximum code rate, discarding part of CSI by adopting a priority principle when the CSI is transmitted on a PUSCH, and transmitting the bound HARQ-ACK bit and the residual CSI on a PUCCH for transmitting the HARQ-ACK bit;

wherein the eighth predetermined condition includes at least:

when the sum of the HARQ-ACK bits and the number of bits of the CSI exceeds the maximum code rate, binding the HARQ-ACK bits, if the sum of the bound HARQ-ACK bits and the number of bits of the CSI exceeds the maximum code rate, discarding part of CSI by adopting a priority principle when the CSI is transmitted on a PUSCH, and transmitting the bound HARQ-ACK bits and the rest of CSI on a target PUCCH;

the target PUCCH is a PUCCH for transmitting CSI; or the target PUCCH is one of PUCCH resources for transmitting HARQ-ACK bits and CSI with the most PRBs; or if the number of PRBs corresponding to the PUCCH resources for transmitting the HARQ-ACK bits and the CSI is the same, the target PUCCH is the PUCCH for transmitting the HARQ-ACK bits;

the ninth predetermined condition includes at least:

the PUCCH format for transmitting the CSI is PUCCH format 2, the simultaneous transmission indication is used for indicating that the PUCCH format 2 supports HARQ-ACK bit and CSI simultaneous transmission, the PUCCH format for transmitting the HARQ-ACK bit is PUCCH format 3/4, and the simultaneous transmission indication is used for indicating that the PUCCH format 3/4 supports HARQ-ACK bit and CSI simultaneous transmission.

It is understood that the above examples 3 and 9 correspond to the second implementation manner of step 14, that is, the transmission manner is determined and transmitted based on the number of feedback scheduling bits, the indication of simulcast, the PUCCH format for transmitting CSI, and the PUCCH format for transmitting HARQ-ACK bits.

Step 16, sending the HARQ-ACK bit and the CSI

It is understood that, based on the transmission mode determined in step 14, the terminal device sends the HARQ-ACK bit and the CSI to the network side device.

In addition, based on the above example, if the determined transmission mode for transmitting the HARQ-ACK bit and the CSI is not unique, the terminal device selects one of the HARQ-ACK bit and the CSI by using a priority rule agreed with the network side device. For example: when the determined transmission mode includes transmission modes 1-4, the priority of the determined transmission mode may be priority of transmission mode 4 > priority of transmission mode 3 > priority of transmission mode 2 > priority of Alt 1 of transmission mode 1 > priority of Alt 2 of transmission mode 1. Of course, it should be understood that the priority rule exemplified herein is one of the optional priority rules and is not limited thereto.

It can be seen that, in this embodiment, when the first time domain resource is the same as or overlaps with the second time domain resource, the transmission of the HARQ-ACK bit and the CSI is determined according to the PUCCH format for transmitting the CSI and the PUCCH format for transmitting the HARQ-ACK bit of the concurrent transmission indication, so as to solve the collision problem of the simultaneous or partially simultaneous transmission of the CSI and the HARQ-ACK bit; furthermore, the present embodiment selects PUCCH resources for transmission by combining or discarding some information to avoid or reduce the impact on HARQ-ACK feedback.

Example 2

Fig. 2 is a schematic flowchart of a method for sending uplink control information according to embodiment 2 of the present invention, and referring to fig. 2, the method may specifically include the following steps:

step 22, the network side equipment sends configuration information to the terminal equipment;

it should be noted that, on the basis of the configuration information recorded in step 12, the configuration information in this step also carries a PUCCH format for transmitting the SR, and the simultaneous transmission indication carried by the configuration information further includes whether the PUCCH format for transmitting the SR and the PUCCH format for transmitting the HARQ-ACK bit support the HARQ-ACK bit and the SR simultaneous transmission.

The simultaneous transmission indication refers to that the network device configures whether a certain PUCCH format supports CSI and HARQ-ACK transmission on one PUCCH by sending a high-level signaling to the mobile terminal device, for example: for PUCCH format 2, if the parameter simultaneousHARQ-ACK-CSI is set to true when PUCCH format 2 is configured, it indicates that PUCCH format 2 supports CSI and HARQ-ACK transmission on one PUCCH. If the parameter simultaneousHARQ-ACK-CSI is set to false, it indicates that PUCCH format 2 does not support CSI and HARQ-ACK transmission on one PUCCH. Similarly, the PUCCH format 3/4 corresponds to whether the corresponding higher layer parameter configuration supports CSI and HARQ-ACK supporting concurrent transmission.

Step 24, when the first time domain resource is the same as or overlapped with the third time domain resource, determining a PUCCH for transmitting HARQ-ACK bits with/with out SR according to the simultaneous transmission indication, the PUCCH format for transmitting HARQ-ACK bits and the PUCCH format for transmitting SR;

the first time domain resource is a time domain resource prepared for sending HARQ-ACK bits, and the third time domain resource is a time domain resource prepared for sending an SR.

It should be understood that, similar to the implementation manner described in embodiment 1, when the first time domain resource is the same as or overlaps with the third time domain resource, the terminal device may determine, based on the simultaneous transmission indication and the PUCCH format for transmitting the HARQ-ACK bit and the PUCCH format for transmitting the SR, transmission manners of the HARQ-ACK bit and the SR, including at least: whether to combine, discard partial information, and which PUCCH resource to use for transmission. Specific examples are:

example 1, SR is completely discarded, and HARQ-ACK bits are transmitted using PUCCH resources transmitting the HARQ-ACK bits. And recording the HARQ-ACK bit as a HARQ-ACK bit with out SR, and recording the PUCCH resource as a PUCCH for transmitting the HARQ-ACK bit with out SR. Corresponding to Alt 1 of transmission scheme 1 in example 1.

For example 2, partially discard the SR, and combine the HARQ-ACK bit + the remaining SR, which is denoted as HARQ-ACK bit with SR. The HARQ-ACK bit with SR is transmitted using a PUCCH resource transmitting the HARQ-ACK bit or a PUCCH resource transmitting the SR. The PUCCH resource for transmission is denoted as PUCCH for transmission of HARQ-ACK bits with SR.

For example 3, without discarding the SR, combine HARQ-AC K bits + SR, and record as HARQ-ACK bits with SR. The HARQ-ACK bit with SR is transmitted using a PUCCH resource transmitting the HARQ-ACK bit or a PUCCH resource transmitting the SR. The PUCCH resource for transmission is denoted as PUCCH for transmission of HARQ-ACK bits with SR.

Although only three examples are listed here, it is understood that the various cases in table 2 in embodiment 1 are also applicable here, and the description thereof is omitted here because the implementation thereof is similar.

Step 26, when the first time domain resource is the same as or overlapped with the second time domain resource, determining the transmission of the HARQ-ACK bit with/without SR and the CSI according to the simultaneous transmission indication, or according to the simultaneous transmission indication, the PUCCH format for transmitting the CSI, and the PUCCH format for transmitting the HARQ-ACK bit with/without SR;

wherein, the first time domain resource is a time domain resource prepared for sending HARQ-ACK bit with/with out SR, the second time domain resource is a time domain resource prepared for sending CSI, and the simultaneous transmission indication at least comprises: whether at least one of the PUCCH format for transmitting the CSI and the PUCCH format for transmitting the HARQ-ACK bits with/with out SR supports simultaneous transmission of the HARQ-ACK bits with/with out SR and the CSI.

It is understood that the PUCCH for transmitting HARQ-ACK bits with/without SR determined in step 24 is used as the PUCCH for transmitting HARQ-ACK bits in embodiment 1, and the transmission of HARQ-ACK bits with/without SR and CSI is determined based on the implementation of determining transmission of HARQ-ACK bits and CSI described in embodiment 1. Since the implementation of the two is similar, the description of step 26 is not repeated here.

In addition, it is understood that, for the present embodiment, the sequence of step 24 and step 26 may be flexibly adjusted, and specific examples may be:

for example 1, when the first time domain resource is the same as or overlaps with the second time domain resource, the transmission mode of the HARQ-ACK bit and the CSI is determined first based on embodiment 1; then, when the first time domain resource is the same as or overlaps with the third time domain resource, the transmission mode of the HARQ-ACK bit with/without CSI and SR is determined.

The implementation manner of determining the transmission manners of the HARQ-ACK bits with/with out CSI and SR is similar to that described in embodiment 1, and therefore, the description thereof is omitted here.

For example 2, when the second time domain resource is the same as or overlaps with the third time domain resource, the transmission modes of the CSI and the SR are determined first; if the determined result is that the CSI with/with out SR is transmitted, when the first time domain resource is the same as or overlaps the second time domain resource, determining transmission of the HARQ-ACK bit and the CSI with/with out SR based on the implementation of determining transmission of the CSI and the HARQ-ACK bit described in embodiment 1; and if the determined result is that the SR with/with out CSI is transmitted, determining the transmission of the HARQ-ACK bit and the SRwith/with out CSI when the first time domain resource is the same as or overlapped with the third time domain resource.

It can be seen that, in this embodiment, based on embodiment 1, an SR is introduced, and when at least two corresponding time domain resources of the HARQ-ACK bit, the CSI, and the SR in the UCI are the same or overlap, the transmission of the UCI with the same or overlapping time domain resources is determined based on the implementation manner for determining the transmission of the HARQ-ACK bit and the CSI described in embodiment 1, so as to solve the collision problem of transmitting the UCI at the same time.
