Description

Method for transmitting control information, terminal equipment and network equipment

Technical Field

The present application relates to the field of communications, and more particularly, to a method, a terminal device and a network device for transmitting control information.

Background

In order to cope with explosive mobile data traffic increase, massive mobile communication device connection, and various new services and application scenarios which are continuously emerging, the fifth generation (5G) mobile communication system is in operation. The International Telecommunications Union (ITU) defines three broad classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), high-reliability and low-latency communications (URLLC), and massive machine type communications (mtc). The URLLC service has extremely high requirement on time delay, and under the condition of not considering reliability, the transmission time delay requirement is within 0.5 millisecond (ms); on the premise of reaching 99.999 percent of reliability, the transmission delay is required to be within 1 ms.

In a Long Term Evolution (LTE) system, the minimum time scheduling unit is a Transmission Time Interval (TTI) with a time length of 1 ms. In order to meet the transmission delay requirement of URLLC traffic, the data transmission of the wireless air interface may use a shorter time scheduling unit, for example, a mini-slot (mini-slot) or a slot with a larger subcarrier interval as a minimum time scheduling unit. Wherein, a mini-slot includes one or more time domain symbols, where the time domain symbols may be Orthogonal Frequency Division Multiplexing (OFDM) symbols. For a timeslot with subcarrier spacing of 15 kilohertz (kHz), including 6 or 7 time domain symbols, the corresponding time length is 0.5 ms; for a time slot with a subcarrier spacing of 60kHz, the corresponding time length is shortened to 0.125 ms. Because data of the URLLC service has burstiness and randomness, in order to improve the utilization rate of system resources, the base station usually does not reserve resources for downlink data transmission of the URLLC service. When the URLLC service data reaches the base station, if there is no idle time-frequency resource, the base station cannot wait for the completion of the transmission of the eMBB service data scheduled this time and then schedule the URLLC service data in order to meet the ultra-short delay requirement of the URLLC service. And the base station allocates resources for URLLC service data in a preemption (preemption) mode.

The terminal equipment feeds back control information to the base station after receiving the eMBB service or the URLLC service sent by the base station so as to inform whether the service is transmitted successfully. At present, there is no solution for how to feed back control information when eMBB service and URLLC service coexist, and therefore a technical solution is urgently needed to be proposed.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

It should be understood that the technical solutions of the embodiments of the present application may be applied to various communication systems, for example: a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, and other current communication systems, and is particularly applicable to a future 5G New Radio (NR) system, a 5G system, or a communication system based on an Orthogonal Frequency Division Multiplexing (OFDM) technology.

Fig. 1 is an architecture diagram of a mobile communication system to which an embodiment of the present application is applied. As shown in fig. 1, the mobile communication system includes a core network device 110, a radio access network device 120, and at least one terminal device (e.g., a terminal device 130 and a terminal device 140 in fig. 1). The terminal equipment is connected with the wireless access network equipment in a wireless mode, and the wireless access network equipment is connected with the core network equipment in a wireless or wired mode. The core network device and the radio access network device may be separate physical devices, or the function of the core network device and the logical function of the radio access network device may be integrated on the same physical device, or a physical device may be integrated with a part of the function of the core network device and a part of the function of the radio access network device. The terminal equipment may be fixed or mobile. It should be understood that fig. 1 is only a schematic diagram, and that other network devices, such as a wireless relay device and a wireless backhaul device (not shown in fig. 1), may also be included in the communication system. The embodiments of the present application do not limit the number of core network devices, radio access network devices, and terminal devices included in the mobile communication system.

The radio access network device is an access device in which the terminal device is accessed to the mobile communication system in a wireless manner, and may be a base station NodeB, an evolved node b, a base station gNB in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, and the like. The radio access network device may also be referred to as a network device.

The Terminal device may also be referred to as a Terminal, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and the like. The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and so on.

The wireless access network equipment and the terminal equipment can be deployed on land, including indoors or outdoors, and are handheld or vehicle-mounted; can also be deployed on the water surface; it may also be deployed on airborne airplanes, balloons and satellite vehicles. The embodiment of the application does not limit the application scenarios of the wireless access network device and the terminal device.

The embodiments of the present application may be applicable to downlink signal transmission, may also be applicable to uplink signal transmission, and may also be applicable to device-to-device (D2D) signal transmission. For downlink signal transmission, the sending device is a radio access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is a radio access network device. For D2D signaling, the sending device is a terminal device and the corresponding receiving device is also a terminal device. The embodiment of the present application does not limit the transmission direction of the signal.

The radio access network device and the terminal device, and the terminal device may communicate via a licensed spectrum (licensed spectrum), may communicate via an unlicensed spectrum (unlicensed spectrum), and may communicate via both the licensed spectrum and the unlicensed spectrum. The radio access network device and the terminal device may communicate with each other through a frequency spectrum of less than 6 gigahertz (GHz), may communicate through a frequency spectrum of more than 6GHz, and may communicate by using both a frequency spectrum of less than 6GHz and a frequency spectrum of more than 6 GHz. The embodiments of the present application do not limit the spectrum resources used between the radio access network device and the terminal device.

For convenience of description, the description will be made taking the case where the radio access network device is a network device. The network device schedules a resource (e.g., a downlink grant) to transmit downlink data information to a terminal device with non-emergency service (e.g., enhanced mobile broadband (eMBB) service). After receiving a Downlink Shared CHannel (e.g., a Physical Downlink Shared CHannel (PDSCH)), the terminal device needs to feed back CHannel quality to the network device, send an Uplink Control CHannel (e.g., a Physical Uplink Control CHannel (PUCCH)) to the network device, where the Uplink Control CHannel carries feedback information, e.g., Hybrid Automatic Repeat Request (HARQ) ACK/NACK, and acknowledge Downlink data sent on the Downlink Shared CHannel. During the transmission process, there may be a case where Channel State Information (Aperiodic Channel State Information (a-CSI)) and/or feedback Information (e.g., HARQ ACK/NACK) of an emergency service (or a burst service) collides with feedback Information of an eMBB service, for example, the emergency service is an Ultra Reliable and Low Latency Communication (URLLC) service.

Since the terminal device does not have the capability of transmitting two Uplink channels in one carrier, in order to upload the channel state Information and/or feedback Information of the burst service in time, a new solution is proposed in the present application, which intends to transmit Uplink Control Information (UCI) of the non-emergency service and the emergency service through the same Uplink shared channel. Fig. 2 shows a schematic view of a scenario to which an embodiment of the present application is applied. For example, the network device in fig. 2 may be radio access network device 120 in fig. 1, and the terminal device in fig. 2 may be terminal device 130 or terminal device 140 in fig. 1. As shown in fig. 2:

Specifically, the first bit upper limit value and the second bit upper limit value may be configured through higher layer signaling or physical layer signaling, which is not particularly limited.

Specifically, the number of bits of the first UCI is greater than or equal to a first bit upper limit value, all resource regions of the first resource region are used for transmitting the first UCI, and then the terminal device further needs to determine a second resource region on the uplink shared channel, so that the second UCI is transmitted in the second resource region. The number of bits of the first UCI is less than the first bit upper limit value, and the sum of the number of bits of the first UCI and the number of bits of the second UCI is greater than or equal to the first bit upper limit value, the first resource region may transmit not only the first UCI, but also a resource region excluding a resource used for transmitting the first UCI in the first resource region may transmit the second UCI, and at this time, the terminal device needs to determine, on the uplink shared channel, that the second resource region is used for transmitting the second UCI. Accordingly, the terminal device may determine the first resource region and the second resource region on the uplink shared channel.

Or, if the sum of the number of bits of the first UCI and the number of bits of the second UCI is less than or equal to the second bit upper limit value, the first resource region may satisfy the transmission of the first UCI and the second UCI, and the terminal device only needs to determine the first resource region on the uplink shared channel without determining the second resource region.

In summary, the terminal device may determine the first resource region and/or the second resource region according to the number of bits of the first UCI and the number of bits of the second UCI.

Optionally, the method 300 further comprises:

the network device sends first Downlink Control Information (DCI), where the first Downlink Control Information is used to indicate sending the second UCI and/or resource Information used to send the second UCI.

Correspondingly, the terminal equipment receives the first downlink control information.

In the embodiment of the application, the terminal device may determine the second resource region based on the content indicated in the first downlink control information; the first resource region and/or the second resource region may also be determined based on a reception time of the first downlink control information. These cases are described in detail below.

Optionally, as an embodiment, if the first downlink control information is used to indicate resource information of the second UCI, the terminal device may determine, according to the resource information of the second UCI, a second resource region in the uplink shared channel, where the resource information of the second UCI may include: information of an uplink control channel resource, where the uplink control channel resource is used to carry the second UCI.

Specifically, the determining, by the terminal device, the second resource region in the uplink shared channel according to the resource information of the second UCI includes:

the resource information of an uplink control channel (such as PUCCH) comprises a time domain starting position of the resource of the uplink control channel, and the terminal equipment determines the time domain starting position of the second resource region according to the time domain starting position of the resource of the uplink control channel; and/or the presence of a gas in the gas,

Alternatively, the number of symbols of the second resource region may be less than or equal to the duration of the resource of the uplink control channel, or may have a fixed correspondence with the duration of the resource of the uplink control channel. For example, the number of symbols of the second resource region may be equal to the duration of the resource of the uplink control channel minus X, where X may be a predefined number of symbols.

Optionally, the time domain starting position or the time domain length of the second resource region may be a symbol where a Demodulation Reference Signal (DMRS) or other Reference signals are avoided. Alternatively, the second resource region may be continuous or discontinuous in the time domain, which is not limited to this.

Therefore, the terminal device may determine the second resource region according to the content specifically included in the resource information of the uplink control channel.

Optionally, as an embodiment, the terminal device may determine the time domain position of the second resource region according to the receiving time of the first downlink control information.

In particular, the time domain position of the second resource region may be a time domain start position and/or a time domain end position of the second resource region. Optionally, the receiving time of the first downlink control information may be a receiving time of a downlink control channel where the first downlink control information is located. Here, taking a as an example, a may be the first downlink control information or the downlink control channel in which the first downlink control information is located. The reception time of a may be the start time of reception a, may be the end time of reception a, may be the start symbol of a, and may be the end symbol of a, which is not limited.

Alternatively, the time domain starting position of the second resource region may be the same as the time domain starting position of the resource of the uplink control channel. Optionally, the time domain position of the second resource region may also be after the time domain starting position of the resource of the uplink control channel, where the first available data symbol carrying the uplink shared channel may be used as the time domain starting position of the second resource region.

Therefore, the terminal device may determine the time domain position of the second resource region according to the reception time of the first downlink control information.

The above describes that the terminal device determines the specific location of the second resource region in detail according to the content indicated by the first downlink control information or the reception time of the first downlink control information. A specific case where the terminal device determines the first resource region and/or the second resource region according to the reception time of the first downlink control information will be described below.

It should be understood that the determination manner of the specific location of the second resource region described above by those skilled in the art can be used in reasonable combination with the case of the second resource region determined below, and the embodiment of the present application does not limit this.

Optionally, as an embodiment, the determining the first resource region and/or the second resource region on the uplink shared channel includes:

and N symbols of the receiving time of the first downlink control information before the starting time of the uplink shared channel are provided, wherein N is greater than or equal to 0, the terminal equipment determines a first resource area or determines the first resource area and a second resource area, and the first resource area is also used for mapping the second control information.

For example, if the receiving time of the first uplink control information is N symbols before the starting time of the uplink shared channel, where N is greater than or equal to 0, and the second uplink control information is ready to be transmitted on the first resource region at this time, the terminal device transmits the first uplink control information and the second uplink control information on the first resource region. Or, although the second uplink control information is ready to be transmitted on the first resource region, the first resource region can transmit only part of the information of the second uplink control information, and at this time, the terminal device needs to determine the second resource region in order to transmit the remaining information of the second uplink control information.

Specifically, the first resource region determined by the terminal device is used for transmitting not only the first uplink control information but also the second uplink control information. Or, in a first resource region and a second resource region determined by the terminal device, a partial region of the first resource region is used for transmitting first uplink control information, and a resource region and a second resource region in the first resource region except for the resource region used for transmitting the first uplink control information are used for transmitting second uplink control information.

Or, the receiving time of the first downlink control information is M symbols before or after the starting time of the uplink shared channel, where M is greater than or equal to 0, and the terminal device determines the second resource region.

For example, the receiving time of the first downlink control information is M symbols before or after the starting time of the uplink shared channel, and at this time, the second uplink control information is not ready to be transmitted on the first resource region, and the terminal device needs to determine that the second resource region is used for transmitting the second uplink control information.

Specifically, the second resource region determined by the terminal device is used for transmitting the second uplink control information, and at this time, all regions of the first resource region are used for transmitting the first uplink control information.

In summary, the terminal device may determine the second resource region based on the specific content indicated in the first downlink control information, or may determine the first resource region and/or the second resource region based on the receiving time of the first downlink control information.

An embodiment in which the terminal device determines the second resource region based on the first resource region will be described below.

Optionally, determining the first resource region and/or the second resource region on the uplink shared channel includes:

determining the first resource region on the uplink shared channel;

Optionally, determining the second resource region on the uplink shared channel according to the first resource region includes:

For example, it may be configured by predefined or higher layer signaling: a time interval from an end symbol of the first resource region to the second resource region. Or the time domain position of the second resource region is all or part of the time domain position of the first resource region.

For another example, the frequency domain location of the second resource region may be all or part of the frequency domain location of the first resource region.

Optionally, the method 300 may further include:

and determining a second mapping mode.

Specifically, determining the second mapping manner includes:

Optionally, the third upper bit limit value is an upper limit value of the number of bits that can be carried by the first resource region. The third bit upper limit value may be predefined or preconfigured.

Optionally, the fourth bit upper limit value is an upper limit value of the number of bits that can be carried by the first resource region. The fourth bit upper limit value may be predefined or preconfigured.

Optionally, the fifth bit upper limit value is an upper limit value of the number of bits that can be carried by the first resource region. The fifth bit upper limit value may be predefined or preconfigured.

Optionally, the third bit upper limit value, the fourth bit upper limit value, and the fifth bit upper limit value are the same or different, and are not limited thereto.

Specifically, if the number of bits of the first UCI is greater than or equal to the third upper limit value of bits, the terminal device maps the first UCI in the first resource region by using a first mapping manner, and maps the second UCI in the second resource region by using a second mapping manner, where the first mapping manner is different from the second mapping manner.

Or, if the sum of the number of bits of the first UCI and the number of bits of the second UCI is smaller than the fourth bit upper limit value, the terminal device maps the first UCI and the second UCI in the first resource region in the same mapping manner, that is, the first mapping manner and the second mapping manner are the same.

Or, if the number of bits of the first UCI is less than the fifth upper limit value of bits, and the sum of the number of bits of the first UCI and the number of bits of the second UCI is greater than or equal to the fifth upper limit value of bits, the terminal device maps partial information of the first UCI and the second UCI in the first resource region by using the first mapping manner, and maps information excluding the partial information of the second UCI in the second resource region by using the second mapping manner.

In summary, the terminal device may determine the first mapping manner and/or the second mapping manner according to the bit number of the first UCI and the bit number of the second UCI.

Correspondingly, the network device may also determine the second mapping manner by using the manner used by the terminal device, which is not described herein for brevity.

It should be understood that, in the embodiment of the present application, the timing for determining the second mapping manner is not limited, and may be before determining the second resource region or after determining the second resource region.

To facilitate understanding of the embodiments of the present application by those skilled in the art, the following description will be given with reference to specific examples. It should be understood that the examples in fig. 4 to 7 are only for facilitating the understanding of the embodiments of the present application by those skilled in the art, and are not intended to limit the embodiments of the present application to the specific scenarios illustrated. It will be apparent to those skilled in the art that various equivalent modifications or variations are possible in light of the examples shown in fig. 4-7, and such modifications or variations are intended to be included within the scope of the embodiments of the present application. For convenience of description, the first UCI is HARQ-ACK1, the second UCI is HARQ-ACK2 (or a-CSI), and the uplink shared channel is PUSCH.

Fig. 4 shows a schematic diagram of an example according to an embodiment of the application. As shown in fig. 4, the terminal device generates HARQ-ACK1 after receiving PDSCH _1 demodulation for feedback to the network device. The terminal device generates HARQ-ACK2 upon receiving PDSCH _2 demodulation for feedback to the network device. In the prior art, HARQ-ACK2 is carried in a short Physical Uplink Control CHannel (s-PUCCH). If the time domain starting position at which the terminal device generates HARQ-ACK2 is after the first resource region carrying HARQ ACK1, then the terminal device determines that HARQ-ACK2 is mapped in a punctured manner in the second resource region. Wherein HARQ-ACK1 is mapped in the first resource region in a rate-matched manner. The second resource region begins with the first available symbol after HARQ-ACK2 is generated. The first resource region and the second resource region are in the same PUSCH. Optionally, the first resource region and the second resource region are different in time domain and the same in frequency domain. In the lower diagram of fig. 4, HARQ-ACK1 is represented by a white box and HARQ-ACK2 is represented by a black box.

Fig. 5 shows a schematic diagram of another example according to an embodiment of the application. As shown in fig. 5, the terminal device generates HARQ-ACK1 after receiving PDSCH _1 demodulation for feedback to the network device. The terminal device generates HARQ-ACK2 upon receiving PDSCH _2 demodulation for feedback to the network device. If the time domain starting position at which the terminal device generates HARQ-ACK2 is in the first resource region carrying HARQ-ACK1, overlaps with the starting position of the first resource region, and the first resource region is already occupied by HARQ-ACK1, the terminal device determines that HARQ-ACK2 is mapped in a punctured manner in the second resource region. Wherein HARQ-ACK1 is mapped in the first resource region in a rate-matched manner. The first resource region and the second resource region are in the same PUSCH. Optionally, the first resource region and the second resource region are different in time domain and the same in frequency domain. In the lower diagram of fig. 5, HARQ-ACK1 is represented by a white box and HARQ-ACK2 is represented by a black box.

Optionally, a partial region of the first resource region may also be used for transmission of HARQ-ACK2 if the number of bits that the first resource region can carry is greater than the number of bits of HARQ-ACK 1. Fig. 6 shows a schematic diagram of yet another example according to an embodiment of the application. As shown in FIG. 6, it is different from FIG. 5 in that partial information of HARQ-ACK1 and HARQ-ACK2 is mapped in a first resource region in a rate-matched manner. Other information of HARQ-ACK2 is mapped in a punctured manner in the second resource region.

Therefore, the uplink HARQ information of the terminal equipment can be comprehensively fed back, so that the network equipment can completely master the receiving quality of the downlink data. In the lower diagram of fig. 6, HARQ-ACK1 is represented by a white box and HARQ-ACK2 is represented by a black box.

Fig. 7 shows a schematic diagram of another example according to an embodiment of the application. As shown in FIG. 7, if the time domain starting position of the terminal device for generating HARQ-ACK2 is in the first resource region carrying HARQ-ACK1, overlaps with the starting position of the first resource region, and the first resource region is not occupied by HARQ-ACK1, and the sum of the number of bits of HARQ-ACK1 and the number of bits of HARQ-ACK2 is less than or equal to the number of bits that the first resource region can carry, the terminal device determines that HARQ-ACK1 and HARQ-ACK2 are both mapped in the first resource region in a rate-matched manner. At this time, the time domains mapped in the first resource region by the HARQ-ACK1 and the HARQ-ACK2 are the same, and the frequency domains are different. In the lower diagram of fig. 7, HARQ-ACK1 is represented by a white box and HARQ-ACK2 is represented by a black box.

Alternatively, HARQ-ACK2 may be mapped to a resource region in the first resource region to which HARQ-ACK1 is not mapped. The time domain part mapped in the first resource region by HARQ-ACK1 and HARQ-ACK2 is the same, and the frequency domain part is the same.

In summary, the terminal device maps HARQ-ACK1 and HARQ-ACK2 on the same PUSCH, which is helpful for meeting the communication requirement when the user has burst traffic or emergency traffic, and increases cell coverage, so that the network device completely grasps the reception quality of downlink data.

That is, the starting symbol of UCI mapped on PUSCH is not earlier than the starting symbol originally allocated to PUCCH for carrying UCI.

Here, the specific mapping of the first UCI and the second UCI in the shared channel described above is applicable to the first resource region and the second resource region described above. Accordingly, the same applies to the "alignment of the start symbol positions".

Optionally, the demodulation reference signal includes a DMRS signal and a Phase-tracking reference signal (PT-RS).

For example, the UCI includes HARQ-ACK and CSI, and the mapping of UCI in the uplink shared channel may include the following:

one way is HARQ-ACK mapping first and CSI mapping second (it should be understood that the mapping order of HARQ-ACK and CSI is not limited here). Wherein, HARQ-ACK is required to be avoided during CSI mapping. And, the mapping of HARQ-ACK and the mapping of CSI both need to avoid the above demodulation reference signal. This will be described in connection with the examples in fig. 8 and 9. For example, in fig. 8, the PUCCH carrying the HARQ-ACK arrives first, and the starting symbol of the PUCCH carrying the HARQ-ACK corresponds to the position carrying the DMRS on the PUSCH, and the starting position mapped to the PUSCH is the first symbol after the DMRS ends. The starting symbol of mapping of the CSI on the PUSCH is aligned with the starting symbol of the PUCCH carrying the CSI. For another example, in fig. 9, the PUCCH carrying CSI arrives first, the starting symbol of the PUCCH carrying CSI mapped on PUSCH is aligned with the starting symbol of the PUCCH carrying CSI, and the starting symbol of the HARQ-ACK mapped on PUSCH is aligned with the starting symbol of the PUCCH carrying HARQ-ACK. And when the CSI mapping is not finished, starting the mapping by the HARQ-ACK, stopping the mapping by the CSI, and starting the mapping by the first available symbol of the rest bits after the HARQ-ACK mapping is finished.

The other method is HARQ-ACK mapping first and CSI mapping later, wherein symbols mapped by CSI are immediately behind HARQ-ACK, and the mapping of HARQ-ACK and the mapping of CSI both need to avoid the demodulation reference signal.

Optionally, if there are redundant bits unmapped when mapping of CSI is completed, the unmapped bits may be directly discarded, or the unmapped bits may be rotated to the start position of the mappable area for mapping, which is not limited herein. The examples in fig. 10 and 11 are described here. For example, in fig. 10, a PUCCH carrying CSI comes first, followed by a PUCCH carrying HARQ-ACK, CSI is not mapped first, HARQ-ACK is mapped preferentially, and the starting symbol of the PUSCH on which HARQ-ACK is mapped is aligned with the starting symbol of the PUCCH carrying HARQ-ACK. And after the HARQ-ACK mapping is finished, the CSI starts to be mapped. Until the resource region configured for the uplink control information on the PUSCH is used up. If there are bits of the PUSCH that have not been mapped, these bits can be directly discarded without transmission. For another example, in fig. 11, a PUCCH carrying CSI comes first, followed by a PUCCH carrying HARQ-ACK, CSI is not mapped first, HARQ-ACK is mapped preferentially, and the starting symbol of the PUSCH on which HARQ-ACK is mapped is aligned with the starting symbol of the PUCCH carrying HARQ-ACK. And after the HARQ-ACK mapping is finished, the CSI starts mapping. Until the resource region configured on the PUSCH for carrying the uplink control information is used up, the CSI has bits which are not mapped, and the bits are returned to the starting position configured on the PUSCH for carrying the resource region of the uplink control information to continue mapping.

It should be understood that the examples in fig. 8 to 11 are only for facilitating the understanding of the embodiments of the present application by those skilled in the art, and are not intended to limit the embodiments of the present application to the specific scenarios illustrated. It will be apparent to those skilled in the art that various equivalent modifications or variations are possible in light of the examples shown in fig. 8-11, and such modifications or variations are intended to be included within the scope of the embodiments of the present application.
