Description

Uplink control information sending method, terminal and network side equipment

Technical Field

The present invention relates to the field of wireless technologies, and in particular, to a method, a terminal, and a network side device for sending uplink control information.

Background

In the existing uplink transmission, when there is an overlap between time-frequency resources of a physical uplink control channel (Physical Uplink Control Channel, PUCCH) and a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) in the same slot, if a condition of uplink control information (Uplink Control Information, UCI) multiplexing (UCI multiplexing) is satisfied, a terminal multiplexes UCI transmitted on the PUCCH on the time-frequency resource of PUSCH, and at this time, the terminal transmits only PUSCH and does not transmit PUCCH.

When uplink multi-service resource multiplexing is introduced, burst uplink Ultra high Reliable Ultra low latency communication (uRLLC) service transmission is allowed to preferentially occupy transmission resources of scheduled uplink mobile broadband enhancement (Enhance Mobile Broadband, eMBB) service. However, when the PUSCH time-frequency resource of the ullc service and the PUSCH time-frequency resource of the eMBB service and the PUCCH time-frequency resource of the eMBB service collide at the same time, the UCI of the eMBB service cannot be multiplexed on the PUSCH resource of the eMBB service at this time, which may cause that the UCI of the eMBB service cannot be transmitted.

If the UCI to be sent at this time includes a hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) -return acknowledgement ACK information, the base station may consider that the terminal does not correctly receive the data, and therefore retransmits all downlink data corresponding to the HARQ-ACK information, which results in downlink transmission resource waste.

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 method for sending the uplink control information in the embodiment of the invention is applied to a wireless communication system, wherein the wireless communication system can be a 5G system, an evolution type long term evolution (Evolved Long Term Evolution, eLTE) system or a subsequent evolution communication system.

In the wireless communication system, multiple service types, such as an eMBB service and a ul lc service, are included, in order to support the two service types simultaneously and meet the low latency requirement of the uRLLC service, burst uRLLC transmission is allowed to occupy the scheduled eMBB transmission resources preferentially, and the occupied time-frequency resource positions of the eMBB users are informed through specific downlink control signaling.

For uplink transmission, the time-frequency resource positions of the uplink control channel PUCCH and the physical uplink shared channel PUSCH are configured and dynamically indicated by the base station. When there is overlap between time-frequency resource time domains of PUCCH and PUSCH in the same slot, if the UCI multiplexing condition is satisfied, the terminal multiplexes UCI information sent on PUCCH on time-frequency resource of PUSCH.

If the PUSCH time-frequency resource of the burst URLLC service collides with the PUSCH time-frequency resource of the eMBB service and the PUCCH time-frequency resource of the eMBB service at the same time, UCI of the eMBB service cannot be multiplexed on the PUSCH resource of the eMBB service, which causes a problem that UCI of the eMBB service cannot be transmitted.

In order to solve the problem that the UCI of the eMBB service in the prior art cannot be normally sent to the base station, and the base station needs to retransmit the corresponding downlink data of the HARQ-ACK information contained in the UCI, so as to cause waste of downlink transmission resources, the embodiment of the present invention provides a method for sending uplink control information, when PUSCH resources of the eMBB service are occupied by downlink control information indication, that is, the downlink control information indicates that time-frequency resources of the PUSCH resources are not sent, but when there is a multiplexed UCI on the time-frequency resources of the PUSCH resources, UCI is sent through a target resource, so that UCI multiplexed on the PUSCH resources can be normally sent to the base station.

Optionally, the method for sending uplink control information according to one embodiment of the present invention is applied to a terminal, as shown in fig. 1, and includes:

s110, if there is uplink control information UCI multiplexed on the Physical Uplink Shared Channel (PUSCH) resource to be transmitted in the target time slot, but at least part of the PUSCH resource is indicated not to be transmitted by the downlink control information, transmitting the UCI through the target resource.

According to the above, it should be noted that, in the uplink control information sending method according to the embodiment of the present invention, the applied terminal is a terminal applying the eMBB service, and when a sudden URLLC service occurs, the base station indicates, through the downlink control information, PUSCH resources that cannot be sent by the terminal due to scheduling by the URLLC service. When the UCI meets the condition of multiplexing on the PUSCH resource to be transmitted in the target time slot, but at least part of the PUSCH resource to be transmitted is indicated by the downlink control information not to be transmitted, the UCI is transmitted through the target resource, so that the problem that downlink transmission resources are wasted because the base station needs to retransmit corresponding downlink data of the HARQ-ACK information contained in the UCI when the UCI cannot be normally transmitted to the base station and the UCI comprises the HARQ-ACK information is solved.

Optionally, in step S110, the target resource is a resource capable of performing the UCI transmission among other resources other than the resource indicated as not being transmitted in the PUSCH resource; or, the target resource is a physical uplink control channel PUCCH resource configured for the UCI transmission in the target slot.

Optionally, the method further comprises:

if the PUCCH resource configured for the UCI transmission in the target slot is indicated by the downlink control information to be not transmitted, determining that the target resource is a resource capable of performing the UCI transmission in the other resources;

Specifically, when determining that the UCI multiplexed on the PUSCH resource exists in the target slot, but at least some resources of the PUSCH resource are indicated by downlink control information to be not transmitted, the terminal determines whether PUCCH resources configured for the UCI transmission in the target slot are indicated by downlink control information to be not transmitted, and if the PUCCH resources configured for the UCI transmission in the target slot are indicated by downlink control information to be not transmitted, determines that the target resource is a resource capable of performing the UCI transmission in the other resources; and if the PUCCH resource is not indicated to be not transmitted by the downlink control information, determining that the target resource is the PUCCH resource.

Based on the above manner, if the PUCCH resource configured for UCI transmission in the target slot is not indicated as not transmitted by the downlink control information, that is, the URLLC service does not schedule the PUCCH resource in the target slot, the UCI is returned to be transmitted by the PUCCH resource in the target slot; if the PUCCH resource configured for UCI transmission in the target slot is indicated as not to be transmitted by the downlink control information, that is, the URLLC service also schedules the PUCCH resource in the target slot, the UCI is transmitted through a resource capable of performing the UCI transmission among other resources other than the resource indicated as not to be transmitted in the PUSCH resource.

By adopting the method for sending the uplink control information, UCI sending is ensured in various modes.

Specifically, the specific process of the method for sending uplink control information according to the embodiment of the present invention may be:

the terminal receives downlink control information sent by the network side equipment, and judges whether the PUSCH resources in the target time slot are indicated to be not sent or not through the downlink control information, namely whether all the PUSCH resources can be normally transmitted or not;

if the fact that all the PUSCH resources in the target time slot can be normally transmitted is judged through the downlink control information, the PUSCH resources are normally transmitted;

If the downlink control information judges that at least part of the PUSCH resources in the target time slot are indicated to be not transmitted, determining which time-frequency resources are included in the PUSCH resources indicated to be not transmitted in the target time slot, and determining other resources except the resources indicated to be not transmitted;

further, if it is determined by the downlink control information that at least some of the PUSCH resources in the target slot are indicated as not being transmitted, the terminal determines whether UCI multiplexing exists on the PUSCH resources;

if no UCI multiplexing exists on the PUSCH resource, canceling the PUSCH transmission on the at least part of the resources which are not indicated to be transmitted;

if UCI multiplexing exists on the PUSCH resource, the terminal judges whether the PUCCH resource configured for UCI transmission in the target time slot is indicated to be not transmitted by the downlink control information, namely, whether all the PUCCH resources can normally transmit or not;

if the PUCCH resources configured for UCI transmission in the target time slot are not indicated to be not transmitted by the downlink control information, namely, all normal transmission is performed, returning UCI to the PUCCH resources in the target time slot for transmission, and discarding the transmission of the PUSCH resources; if the PUCCH resource configured for UCI transmission in the target slot is indicated by the downlink control information as not being transmitted, that is, not capable of all normal transmission, UCI is transmitted through a resource capable of performing the UCI transmission among other resources than the resource indicated as not being transmitted in the PUSCH resource.

Specifically, when determining that the PUCCH resource configured for UCI transmission in the target slot is indicated as not transmitted by the downlink control information, that is, not capable of all normal transmissions, it is necessary to further first determine whether there is the target resource in other resources than the resource indicated as not transmitted in the PUSCH resource;

when the target resource capable of sending the UCI exists in other resources, sending the UCI through the target resource; and when the target resource capable of transmitting the UCI does not exist in other resources, the UCI is abandoned to be transmitted.

According to the above procedure, in one embodiment of the method for sending uplink control information according to the embodiment of the present invention, in step S110, when the target resource is configured as a PUCCH resource for UCI transmission in the target slot in the step of sending the UCI through the target resource, after step S110, the method further includes:

and discarding the transmission of the PUSCH resource.

In another embodiment of the method for sending uplink control information according to the embodiment of the present invention, in step S110, in the step of sending the UCI through the target resource, when the target resource is a resource capable of performing UCI sending among other resources other than the resource indicated as not to be sent in the PUSCH resource, the method further includes:

if the target resource exists in the other resources, sending the UCI through the target resource;

Specifically, in determining that the UCI multiplexed on the PUSCH resource exists in the target slot, when at least some resources of the PUSCH resource are indicated not to be transmitted by the downlink control information, whether a target resource exists in other resources may be further determined, and when the target resource exists, the UCI is transmitted through the target resource; when the target resource does not exist, transmission of UCI is abandoned.

In the embodiment of the present invention, the target resource is a resource other than the resource indicated as not being transmitted in the PUSCH resource, and when the UCI transmission can be performed, specifically, the target resource capable of performing UCI transmission and the resource indicated as not being transmitted in the PUSCH resource do not overlap in the time domain, and the target resource includes a plurality of transmission units that are continuous in the time domain.

It should be noted that, in the embodiment of the present invention, one transmission unit may correspond to one orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol. Specifically, the determining whether the target resource exists in the other resources includes:

determining whether a resource block exists in the other resources; wherein the resource block does not overlap with a resource indicated as not being transmitted in the PUSCH resource in the time domain, and includes a plurality of transmission units that are consecutive in the time domain;

if the other resources do not include resource blocks or the resource blocks included in the other resources do not meet the multiplexing condition of the UCI, determining that the target resources do not exist in the other resources;

and if the other resources comprise at least one resource block and the at least one resource block satisfies the multiplexing condition of the UCI, determining one of the resource blocks satisfying the multiplexing condition of the UCI as the target resource.

Therefore, based on the above-mentioned process of judging the target resource, by adopting the method according to the embodiment of the present invention, when it is determined that the UCI multiplexed on the PUSCH resource exists in the target time slot, but at least part of the resources of the PUSCH resource are indicated not to be transmitted by the downlink control information, the method further includes:

wherein the resource block and the resource indicated as not transmitted in the PUSCH resource are not overlapped in the time domain and include a plurality of transmission units consecutive in the time domain. For example, referring to fig. 2, an OFDM symbol is taken as an example for a transmission unit, and a determination manner of a resource block in the embodiment of the present invention is illustrated.

As shown in fig. 2, the PUSCH time-frequency resource of the URLLC service and the PUSCH time-frequency resource of the eMBB service and the PUCCH time-frequency resource of the eMBB service collide at the same time, that is, the 3 rd to 6 th OFDM symbols of the PUSCH time-frequency resource are indicated as being unavailable for transmission, and then the resource block is determined according to the other resources except the resources indicated as being unavailable for transmission in the PUSCH time-frequency resource of the eMBB service. That is, other resources include the 1 st OFDM symbol, the 2 nd OFDM symbol, the 7 th OFDM symbol, and the eMBB PUSCH demodulation reference signal (Demodulation Reference Signal, DMRS) symbol of the eMBB PUSCH.

And selecting a resource which is not overlapped in the time domain with the resource which is not transmitted in the PUSCH resource and is included in a plurality of OFDM symbols which are continuous in the time domain from other resources which are determined to be not used for transmitting, forming a resource block, and determining the number N of the formed resource blocks.

It should be noted that, the minimum number of OFDM symbols included in one resource block may be determined according to the configuration of the DMRS, where the number of OFDM symbols included is at least greater than or equal to the number of the configured eMBBPUSCH DMRS symbols. Specifically, each resource block includes at least two OFDM symbols that are consecutive in the time domain.

According to the above principle, continuing to illustrate with fig. 2, if it is determined that two consecutive OFDM symbols may be formed into one resource block, and the determined resource block needs to be non-overlapping in time domain with the resources indicated as non-transmitting in the PUSCH resources, the current target slot may be determined, among other resources except the resources indicated as non-transmitting in the PUSCH time-frequency resources, the 1 st OFDM symbol, the 2 nd OFDM symbol, and the eMBB PUSCH DMRS symbol of the eMBB PUSCH may be combined into one resource block, and only one resource block, that is, the number n=1 of the resource blocks that may be formed in the other resources may be determined.

Specifically, if n=0, that is, the other resources determined according to the above manner do not include the resource block, it is determined that the target resource does not exist in the other resources, and all OFDM symbols of the PUSCH resource cannot be used for normal transmission, and UCI is not transmitted; if N is more than or equal to 1, further judging whether resource blocks meeting the multiplexing condition of UCI exist in N resource blocks of other resources, and if each resource block does not meet the multiplexing condition of UCI, not sending UCI.

If N is more than or equal to 1, at least one resource block in the N resource blocks meets the multiplexing condition of UCI, and one resource block in the resource blocks meeting the multiplexing condition of UCI is determined as a target resource.

Specifically, if only one of the N resource blocks satisfies the UCI multiplexing condition, selecting the one resource block that satisfies the UCI multiplexing condition as the target resource for transmitting UCI.

Optionally, if the number of resource blocks satisfying the UCI multiplexing condition in the N resource blocks is at least two, the determining that one of the resource blocks satisfying the UCI multiplexing condition is the target resource includes:

That is, specifically, when N >1 and more than 1 resource blocks satisfy the multiplexing condition of UCI, a resource block having a longer time domain, i.e., more OFDM symbols, is preferentially selected for transmitting UCI. When the two resource block time domain lengths are the same, an alternative solution is to preferentially select a resource block containing a preset PUSCH DMRS time domain symbol (i.e., an eMBB PUSCH DMRS symbol in fig. 2) for transmitting UCI.

In the embodiment of the present invention, optionally, when the target resource is a resource capable of performing the UCI transmission among the other resources, in step S110, the transmitting the UCI through the target resource includes:

Specifically, if the target resource includes a preset PUSCH demodulation reference signal DMRS time domain symbol, the first portion transmission unit is the preset PUSCH DMRS time domain symbol;

Specifically, in one embodiment, in the determined resource block for transmitting the UCI, if a preset PUSCH DMRS time domain symbol is included, the eMBB terminal generates a DMRS signal on the preset PUSCH DMRS time domain symbol according to DMRS configuration information indicated in a downlink control signaling of a scheduled PUSCH, that is, the first part of transmission unit is the preset PUSCH DMRS time domain symbol; further, the eMBB terminal selects a certain number and location of RE resources for UCI multiplexing from available Resource Elements (REs) remaining on the Resource block (i.e., the second partial transmission unit) according to the UCI multiplexing rule.

In another embodiment, in the determined resource block for transmitting the UCI, if the determined resource block does not include a preset PUSCH DMRS time domain symbol, the eMBB terminal uses the first M OFDM symbols (first partial transmission unit) of the determined resource block to carry the DMRS, and the number of time domain symbols for carrying the DMRS is the same as the number of time domain symbols of the preset PUSCH DMRS; further, the eMBB terminal generates a DMRS signal on a time domain symbol carrying the DMRS according to DMRS configuration information indicated in a downlink control signaling of a scheduled PUSCH; in addition, the eMBB terminal selects a certain number and position of RE resources for UCI multiplexing from the remaining available resource elements REs (i.e., the second partial transmission unit) on the resource block according to the rule of UCI multiplexing.

Optionally, the method for sending uplink control information according to the embodiment of the present invention, where the sending the UCI through at least part of transmission units in the second part of transmission units outside the first part of transmission units in the target resource includes:

and if the second part transmission unit cannot bear all UCI, taking the HARQ-ACK information in the UCI as a first selection priority and the channel state information (Channel State Information, CSI) report as a second selection priority, and sending part of information of the UCI through the second part transmission unit.

Based on the above manner, after determining that the first part of transmission units in the target resource for UCI transmission bear the demodulation reference signal DMRS and the other remaining second part of transmission units are used for UCI transmission, if the available RE resources of the remaining second part of transmission units cannot bear all UCI information, HARQ-ACK information in UCI is preferentially borne; in the rest UCI, the CSI report with higher priority is preferentially carried so as to ensure that the HARQ-ACK and the CSI report can be preferentially transmitted to the network side equipment, and the problem that the network side equipment cannot acquire the HARQ-ACK in UCI information, and the base station needs to retransmit the corresponding downlink data of the HARQ-ACK information contained in the UCI, so that the downlink transmission resource is wasted is avoided.

When determining whether the resource block in other resources satisfies the multiplexing condition of UCI, the specific condition of UCI transmission may be determined according to the uplink control data transmission, and if the processing delay of PDSCH needs to be satisfied, each condition will not be described in detail here.

According to the above, different application scenarios of the uplink control information sending method according to the embodiment of the present invention are as follows:

example 1

As shown in fig. 3, in the target slot, all time domain symbol resources of the eMBB PUSCH overlap with the URLLC PUSCH, and then all resources of the eMBB PUSCH are indicated by the downlink control information as not transmitted, and the number n=0 of resource blocks of other resources than the resources indicated as not transmitted, that is, the resources indicated as not transmitted do not include other resources, and then the eMBB terminal does not transmit PUSCH and does not transmit UCI.

Example two

As shown in fig. 4, in the target slot, the fourth and fifth time domain symbols of the eMBB PUSCH overlap with the URLLC PUSCH, and may be indicated as not being transmitted by the downlink control information, and the other resources than the resources indicated as not being transmitted are the first three time domain symbols, which do not overlap with the URLLC PUSCH. If it is determined that at least two consecutive time domain symbols in other resources are formed into one resource block, the first three time domain symbols of the eMBB PUSCH may be formed into one resource block, i.e., n=1. When the composed resource block meets the multiplexing condition of UCI, UCI can be sent by the resource block; when the composed resource block does not meet the multiplexing condition of UCI, the eMBB terminal does not transmit PUSCH and does not send UCI.

Example III

As shown in fig. 5, in the target slot, the fourth and fifth time domain symbols of the eMBB PUSCH overlap with the URLLC PUSCH, and may be indicated as not being transmitted by the downlink control information, and the other resources than the resources indicated as not being transmitted are the first three time domain symbols and the second two time domain symbols, which do not overlap with the URLLC PUSCH. If it is determined that at least two consecutive time domain symbols in other resources are formed into one resource block, the first three time domain symbols of the eMBB PUSCH may be formed into one resource block, and the second two time domain symbols may be formed into one resource block, i.e., n=2. If both resource blocks meet the multiplexing condition of the UCI at this time, the resource block with a longer time domain length, that is, the resource block formed by the first 3 time domain symbols is preferentially selected as the target resource, and is used for transmitting the UCI.

In addition, since the first 3 time domain symbols include the preset PUSCH DMRS time domain symbol, when UCI is transmitted, a DMRS signal may be generated on the preset PUSCH DMRS time domain symbol according to DMRS configuration information in downlink control signaling of scheduling eMBB PUSCH and mapped on the preset PUSCH DMRS time domain symbol; further, on the remaining available REs of the first 3 time domain symbols, a certain number and positions of REs are selected to carry UCI according to the multiplexing rule of UCI, and HARQ-ACK information is used as a first selection priority, and CSI report is used as a priority selection sequence of a second selection priority to carry UCI information in sequence.

Example IV

As shown in fig. 6, in the target slot, the third and fourth time domain symbols of the eMBB PUSCH overlap with the URLLC PUSCH, and may be indicated as not being transmitted by the downlink control information, and the other resources than the resources indicated as not being transmitted are the first two time domain symbols and the last three time domain symbols, which do not overlap with the URLLC PUSCH. If it is determined that at least two consecutive time domain symbols in other resources are formed into one resource block, the first two time domain symbols of the eMBBPUSCH may be formed into one resource block, and the last three time domain symbols may be formed into one resource block, i.e., n=2.

Assuming that the resource block formed by the first two time domain symbols does not meet the multiplexing condition of UCI, and the resource block formed by the last three time domain symbols meets the multiplexing condition of UCI, determining the resource block formed by the last three time domain symbols as a target resource for transmitting UCI.

Since the determined resource block for transmitting the UCI does not include the preset PUSCH DMRS time domain symbol, selecting the 1 st time domain symbol on the resource block as the time domain symbol carrying the DMRS; generating a DMRS signal on the time domain symbol according to the DMRS configuration information in the downlink control signaling of the scheduling eMBB PUSCH and mapping the DMRS signal on the time domain symbol;

further, on the remaining available REs except for the 1 st time domain symbol in the last 3 time domain symbols, a certain number and positions of REs are selected to carry UCI according to the multiplexing rule of UCI, and HARQ-ACK information is used as a priority selection sequence of a first selection priority and CSI report is used as a second selection priority to sequentially carry UCI information.

According to the method for sending the uplink control information, when the uplink URLLC service seizes the time-frequency resource for sending the data and the control information of the uplink eMBB service, the UCI is sent through the target resource, so that the problem that the control information of the eMBB service cannot be sent can be solved, and the downlink resource waste caused by the fact that HARQ-ACK information cannot be fed back is avoided.

By adopting the method for sending the uplink control information, when the time-frequency resource of the PUSCH resource of the eMBB terminal is indicated not to be sent through the downlink control information, but the multiplexing UCI exists on the eMBB terminal, the UCI sent by the terminal can be received through the target resource, so that the UCI multiplexed on the PUSCH resource by the terminal can be obtained, and the problem of downlink resource waste caused by the fact that the HARQ-ACK information feedback of the UCI cannot be obtained is avoided.
