Description

Method, terminal and network side equipment for sending uplink control information

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 in time domain between time-frequency resources of a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) in the same slot, if a condition of UCI multiplexing (UCI) for Uplink Control Information (UCI) multiplexing is satisfied, a terminal multiplexes UCI transmitted on the PUCCH on the time-frequency resources of the PUSCH, and at this time, the terminal only transmits the PUSCH and does not transmit the PUCCH.

When introducing uplink multi-service resource multiplexing, allowing burst uplink ultra-high reliable ultra-Low delay Communication (urrllc) service transmission to preferentially occupy the transmission resource of scheduled uplink Mobile Broadband enhanced (eMBB) service. However, when the PUSCH time-frequency resource of the urlllc service, the PUSCH time-frequency resource of the eMBB service, and the PUCCH time-frequency resource of the eMBB service conflict with each other, the UCI of the eMBB service cannot be multiplexed on the PUSCH resource of the eMBB service, which may cause that the UCI of the eMBB service cannot be transmitted.

If the UCI to be sent contains Hybrid Automatic repeat request (HARQ) -return acknowledgement ACK information, the base station considers that the terminal has not correctly received, and retransmits all downlink data corresponding to the HARQ-ACK information, thereby causing downlink transmission resource waste.

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 and specific embodiments.

The sending method of the uplink control information according to the embodiment of the present invention is applied to a wireless communication system, and the wireless communication system may be a 5G system, or an Evolved Long Term Evolution (lte) system, or a subsequent Evolved communication system.

In the wireless communication system, multiple service types may be included, such as an eMBB service and a urrllc service, in order to simultaneously support the two service types and meet the low latency requirement of the uRLLC service, burst uRLLC transmission is allowed to preferentially occupy scheduled eMBB transmission resources, and an occupied time-frequency resource position of an eMBB user is notified through a 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 time domains of time frequency resources of a PUCCH and a PUSCH are overlapped in the same slot, if the condition of UCI multiplexing is met, the terminal can multiplex UCI information sent on the PUCCH on the time frequency resources of the PUSCH.

If the PUSCH time-frequency resource of the bursty URLLC service conflicts 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, and at this time, the problem that UCI of the eMBB service cannot be transmitted is caused.

In order to solve the problem that in the prior art, the UCI of the eMBB service cannot be normally sent to the base station, and the base station needs to retransmit the downlink data corresponding to the HARQ-ACK information contained in the UCI, which causes the waste of downlink transmission resources, an embodiment of the present invention provides a method for sending uplink control information.

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

s110, in a target time slot, if multiplexed uplink control information UCI exists on Physical Uplink Shared Channel (PUSCH) resources to be sent, but at least part of the PUSCH resources are not sent by the indication of downlink control information, the UCI is sent through the target resources.

As described above, in the method for transmitting uplink control information according to the embodiment of the present invention, the terminal to which the eMBB service is applied is a terminal to which an emblc service is applied, and when a bursty URLLC service occurs, the base station may indicate, through the downlink control information, a PUSCH resource that the terminal cannot transmit because of being scheduled by the URLLC service. When UCI meets the condition of multiplexing on PUSCH resources to be sent in a target time slot, but at least part of resources of the PUSCH resources to be sent are not sent by the indication of downlink control information, the UCI is sent through the target resources so as to avoid the problem that the UCI cannot be normally sent to a base station, and when the UCI comprises HARQ-ACK information, the base station needs to retransmit corresponding downlink data of the HARQ-ACK information contained in the UCI, so that downlink transmission resources are wasted.

Optionally, in step S110, the target resource is a resource capable of performing the UCI transmission in other resources except for the resource indicated as not to be 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 resources configured for UCI transmission in the target time slot are not transmitted by the indication of downlink control information, determining the target resources as resources capable of UCI transmission in the other resources;

Specifically, when determining that the multiplexed UCI exists on the PUSCH resource in the target slot but at least part of the PUSCH resource is instructed not to be transmitted by the downlink control information, the terminal determines whether the PUCCH resource configured for UCI transmission in the target slot is instructed not to be transmitted by the downlink control information, and if the PUCCH resource configured for UCI transmission in the target slot is instructed not to be transmitted by the downlink control information, determines that the target resource is a resource capable of UCI transmission among the other resources; and if the PUCCH resource is not indicated as not to be transmitted by the downlink control information, determining the target resource as 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 PUCCH resource in the URLLC service unscheduled target slot, the UCI is returned to the PUCCH resource in the target slot for transmission; if the PUCCH resource configured for UCI transmission in the target slot is not indicated by the downlink control information, that is, the URLLC service also schedules the PUCCH resource in the target slot, the UCI can be transmitted by the resource that is capable of UCI transmission, among other resources than the resource indicated as not being transmitted in the PUSCH resource.

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

Specifically, the specific process of the method for sending the 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 resource in the target time slot is 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 all PUSCH resources in the target time slot can be normally transmitted according to the downlink control information, the PUSCH resources are normally transmitted;

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

further, if at least part of resources of the PUSCH resources in the target time slot are judged to be not transmitted through the downlink control information, the terminal judges whether UCI multiplexing exists on the PUSCH resources;

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

if the PUSCH resources are subjected to UCI multiplexing, the terminal judges whether PUCCH resources configured for UCI transmission in the target time slot are not transmitted by the downlink control information indication, namely whether the PUCCH resources can be transmitted normally or not;

if the PUCCH resources configured for UCI transmission in the target time slot are not indicated as not transmitted by the downlink control information, namely all normal transmission can be realized, returning the UCI to the PUCCH resources in the target time slot for transmission again, and abandoning the transmission of the PUSCH resources; if the PUCCH resources configured for UCI transmission in the target slot are not indicated by the downlink control information, that is, all normal transmissions are not possible, UCI can be transmitted by the resource that performs UCI transmission, among other resources except the resource indicated as not being transmitted in the PUSCH resources.

Specifically, when it is determined that a PUCCH resource configured for UCI transmission in a target slot is indicated by downlink control information as non-transmission, that is, all normal transmissions cannot be performed, it is further required to first determine whether the target resource exists in other resources except the resource indicated as non-transmission in the PUSCH resource;

when other resources have target resources capable of transmitting the UCI, transmitting the UCI through the target resources; 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 the method for transmitting uplink control information according to the embodiment of the present invention, in step S110, in the step of transmitting the UCI through the target resource, when the target resource is a PUCCH resource configured for UCI transmission in the target slot, after step S110, the method further includes:

and abandoning the transmission of the PUSCH resource.

In another embodiment of the method for transmitting uplink control information according to the embodiment of the present invention, in step S110, when a target resource is a resource that can perform UCI transmission in a resource other than a resource indicated as not to be transmitted in the PUSCH resource in the step for transmitting the UCI by the target resource, the method further includes:

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

Specifically, when it is determined that the multiplexed UCI exists on the PUSCH resource in the target timeslot, but at least part of the resources of the PUSCH resource are not sent by the indication of the downlink control information, it may be further determined whether a target resource exists in other resources, and when the target resource exists, the UCI is sent through the target resource; when the target resource does not exist, transmission of the UCI is abandoned.

In the embodiment of the present invention, when the target resource is a resource that can perform UCI transmission among other resources except the resource indicated as non-transmission in the PUSCH resource, specifically, the target resource that can perform UCI transmission and the resource indicated as non-transmission in the PUSCH resource are not overlapped in a time domain, and the target resource includes a plurality of transmission units that are consecutive 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 (OFDM) symbol. Specifically, the determining whether the target resource exists in the other resources includes:

determining whether resource blocks exist in the other resources; wherein the resource block is not overlapped with a resource which is indicated as not to be transmitted in the PUSCH resource in a time domain, and comprises a plurality of transmission units which are continuous in the time domain;

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

and if the other resources comprise at least one resource block and the included at least one resource block meets the multiplexing condition of the UCI, determining one resource block meeting the multiplexing condition of the UCI in the resource blocks as the target resource.

Therefore, based on the above process of determining the target resource, when determining that the multiplexed UCI exists on the PUSCH resource in the target timeslot but at least part of the PUSCH resource is not sent by the indication of the downlink control information, the method according to the embodiment of the present invention further includes:

wherein the resource block is not overlapped with the resource indicated as not to be transmitted in the PUSCH resource in a time domain, and comprises a plurality of transmission units which are continuous in the time domain. For example, referring to fig. 2, taking an example that one transmission unit corresponds to one OFDM symbol, the determination method of the resource block in the embodiment of the present invention is illustrated.

As shown in fig. 2, the PUSCH time-frequency resources of the URLLC service, the PUSCH time-frequency resources of the eMBB service, and the PUCCH time-frequency resources of the eMBB service simultaneously collide, that is, the 3 rd to 6 th OFDM symbols of the PUSCH time-frequency resources are indicated as being not capable of being used for transmission, and then the resource block is determined according to the other resources except the resources indicated as not being capable of being used for transmission in the PUSCH time-frequency resources of the eMBB service. That is, the other resources include 1 st OFDM symbol, 2 nd OFDM symbol, 7 th OFDM symbol, and eMBB PUSCH Demodulation Reference Signal (DMRS) symbol of the eMBB PUSCH.

And selecting resources other than the resources indicated as being incapable of being used for transmission, wherein the resources are not overlapped with the resources indicated as not being transmitted in the PUSCH resources in the time domain, and a plurality of OFDM symbols which are continuous in the time domain are combined into one resource block, and determining the number N of the combined resource blocks.

The minimum number of OFDM symbols included in one resource block may be determined according to the DMRS configuration, and the number of included OFDM symbols is at least equal to or greater than the number of configured embbbpusch DMRS symbols. Specifically, each resource block includes at least two OFDM symbols consecutive in a time domain.

According to the above principle, continuing to illustrate with fig. 2, if it is determined that two consecutive OFDM symbols may constitute one resource block, and the determined resource block needs to be non-overlapped with a resource indicated as non-transmission in the PUSCH resource in the time domain, a current target slot may be determined, and among other resources than the resource indicated as not being available for transmission in the PUSCH time-frequency resource, 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 may be determined, that is, the number N of resource blocks that can be constituted in other resources is 1.

Specifically, if N is 0, that is, if the resource block is not included in the other resources determined according to the above method, 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, the UCI is not sent; if N is larger than or equal to 1, whether resource blocks meeting the multiplexing condition of UCI exist in N resource blocks of other resources needs to be further judged, and if each resource block does not meet the multiplexing condition of UCI, the UCI is not sent.

And if N is larger than or equal to 1, at least one resource block in the N resource blocks meets the multiplexing condition of the UCI, and determining one resource block meeting the multiplexing condition of the UCI in the resource blocks as a target resource.

Specifically, if only one resource block of the N resource blocks meets the multiplexing condition of the UCI, the only resource block meeting the multiplexing condition of the UCI is selected as the target resource for transmitting the UCI.

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

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

In this 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 part of transmission units is the preset PUSCH DMRS time domain symbol;

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

In another embodiment, if the determined resource block for transmitting the UCI does not include the preset puschhdmrs time domain symbol, the eMBB terminal uses the first M OFDM symbols (first partial transmission units) of the determined resource block to carry the DMRS, and the number of the time domain symbols for carrying the DMRS is the same as the number of the time domain symbols for carrying 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 downlink control signaling for scheduling the PUSCH; in addition, according to the UCI multiplexing rule, the eMBB terminal selects a certain number and position of RE resources from the remaining available resource elements REs (i.e., the second partial transmission units) on the resource block for 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 some transmission units in a second part of transmission units outside the first part of transmission units in the target resource includes:

and if the second part of transmission units cannot bear all the UCI, using hybrid automatic repeat request HARQ-return acknowledgement ACK information in the UCI as a first selection priority and a Channel State Information (CSI) report as a second selection priority, and sending part of information of the UCI through the second part of transmission units.

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

It should be noted that when determining whether resource blocks in other resources satisfy the multiplexing condition of the UCI, the ue may determine, according to specific conditions for UCI transmission during uplink control data transmission, if it needs to satisfy the processing delay of the PDSCH, and the like, and each condition is not described in detail herein.

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

example one

As shown in fig. 3, in the target slot, all time domain symbol resources of the eMBB PUSCH overlap with the URLLC PUSCH, and all resources of the eMBB PUSCH are instructed not to be transmitted by the downlink control information, and the number N of resource blocks of other resources than the resources instructed not to be transmitted is 0, that is, other resources are not included outside the resources instructed not to be transmitted, and the eMBB terminal does not transmit the PUSCH and does not transmit UCI.

Example two

As shown in fig. 4, in the target timeslot, the fourth and fifth time domain symbols of the eMBB PUSCH overlap with the URLLC PUSCH and are not indicated to be transmitted by the downlink control information, and the other resources except the resource indicated to be not transmitted are the first three time domain symbols and do not overlap with the URLLC PUSCH. If it is determined that at least two consecutive time domain symbols in other resources form one resource block, the first three time domain symbols of the eMBB PUSCH may form one resource block, that is, N ═ 1. When the composed resource block meets the multiplexing condition of the UCI, the UCI can be sent through the resource block; and when the composed resource block does not meet the multiplexing condition of the UCI, the eMBB terminal does not transmit the PUSCH and does not send the UCI.

EXAMPLE III

As shown in fig. 5, in the target timeslot, the fourth and fifth time domain symbols of the eMBB PUSCH overlap with the URLLC PUSCH and will be indicated as not transmitted by the downlink control information, and other resources except the resources indicated as not transmitted are the first three time domain symbols and the last two time domain symbols, and do not overlap with the URLLC PUSCH. If it is determined that at least two consecutive time domain symbols in other resources form one resource block, the first three time domain symbols of the eMBB PUSCH may form one resource block, and the last two time domain symbols may form one resource block, that is, N ═ 2. If both resource blocks meet the multiplexing condition of the UCI, the resource block with a longer time domain length, that is, the resource block composed of the first 3 time domain symbols, is preferentially selected as the target resource for transmitting the UCI.

In addition, because 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 the downlink control signaling for scheduling the eMBB PUSCH and may be 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 according to a multiplexing rule of UCI to carry UCI, and the UCI information is sequentially carried in a priority selection order in which HARQ-ACK information is used as a first selection priority and a CSI report is used as a second selection priority.

Example four

As shown in fig. 6, in the target timeslot, the third and fourth time domain symbols of the eMBB PUSCH overlap with the URLLC PUSCH and will be indicated as not transmitted by the downlink control information, and other resources except the resources indicated as not transmitted are the first two time domain symbols and the last three time domain symbols, and do not overlap with the URLLC PUSCH. If it is determined that at least two consecutive time domain symbols in other resources form one resource block, the first two time domain symbols of the embbbpusch may form one resource block, and the last three time domain symbols may form one resource block, that is, N ═ 2.

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

Selecting the 1 st time domain symbol on the resource block as the time domain symbol for bearing the DMRS because the determined resource block for transmitting the UCI does not comprise the preset PUSCH DMRS time domain symbol; generating a DMRS signal on the time domain symbol according to DMRS configuration information in downlink control signaling for scheduling eBBPUSCH 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 a multiplexing rule of UCI, and UCI information is sequentially carried in a priority selection order in which HARQ-ACK information is used as a first selection priority and a CSI report is used as a second selection priority.

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