Description

Technical Field

Background

Future fifth generation (5G) mobile communication systems need to adapt to diversified scenarios and service requirements. The main scenes of the 5G Mobile Communication system include enhanced Mobile Broadband (eMBB), Ultra-high Reliable and Ultra-Low Latency Communication (URLLC), and Massive Machine Type Communication (mtc), and these scenes have requirements on the system such as high reliability, Low Latency, large bandwidth, and wide coverage. For some terminal devices that may support services with different numerical configurations (numerology), uplink control channels under multiple numerologies may be received simultaneously.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the invention can be applied to various communication systems, such as: a Long Term Evolution (LTE)/enhanced Long Term Evolution (LTE-a) system, a New Radio (NR) system, and the like.

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

A network device, which is deployed in a radio access network device and is used for providing a wireless communication function for a terminal device, may be a base station, and the base station may be an evolved node B (eNB) or an e-NodeB in LTE and a 5G base station (gNB).

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

It should be noted that, first, the network device configures a PUCCH resource set for the UE. One or more resources in the resource set are then indicated by the DCI for transmission of UCI information corresponding to the one or more priorities. In the embodiment of the present invention, the collision of one PUCCH resource with another PUCCH resource in the time domain may be understood as: there is an overlapping portion of one PUCCH resource and another PUCCH resource in the time domain. The service priority corresponding to the UCI may also be understood as a transmission priority of the UCI.

FIG. 1 illustrates a method of information transfer according to one embodiment of the present application. The method shown in fig. 1 may be performed by a network device. As shown in fig. 1, the method comprises:

s110, sending first downlink control information DCI, where the first DCI indicates a first physical uplink control channel PUCCH resource for transmitting first uplink control information UCI, and the first UCI corresponds to a first service priority.

And S120, sending a second DCI, where the second DCI indicates N second PUCCH resources, a target second PUCCH resource of the N second PUCCH resources is used for transmitting a second UCI, N-1 second PUCCH resources except the target second PUCCH resource of the second PUCCH resources are used for transmitting the first UCI, the N second PUCCH resources do not collide in a time domain, the second UCI corresponds to a second service priority, and N is a positive integer greater than or equal to 2.

Optionally, in some embodiments, the first traffic priority is lower than said second traffic priority. In this case, S110 and S120 can be understood as: the network device indicates, for the terminal device, a first PUCCH resource for transmitting first Uplink Control Information (UCI) corresponding to a low traffic priority through first Downlink Control Information (DCI), and indicates, for the terminal device, N time-domain non-colliding second PUCCH resources through second DCI, where one PUCCH resource of the N second PUCCH resources is used for transmitting a second UCI corresponding to a high traffic priority, and one second PUCCH resource of the N second PUCCH resources, excluding a second PUCCH used for transmitting the second UCI, is used for transmitting the first UCI. The first UCI may be, for example, UCI of eMBB service, and the second UCI is UCI of URLLC service.

That is to say, a new PUCCH resource indication manner may be defined in DCI indicating a PUCCH resource corresponding to UCI with high traffic priority, so that the DCI indicates N PUCCH resources that do not collide in a time domain, where one PUCCH resource is used to transmit UCI with high traffic priority and the other N-1 PUCCH resources are used to transmit UCI with low traffic priority.

Optionally, in some embodiments, the second UCI includes Hybrid automatic repeat Request (HARQ) feedback information. For example, the second UCI includes HARQ-ACK information.

The indication of PUCCH resources may be indicated by a PUCCH resource indication field of the DCI, e.g. for a second DCI, one state of the PUCCH resource indication field may indicate N resources, and different states may indicate different N resources.

S130, if the first PUCCH resource collides with the target second PUCCH resource in a time domain, receiving the first UCI through one second PUCCH resource of the N-1 second PUCCH resources, and receiving the second UCI through the target second PUCCH resource.

Optionally, in S130, the target second PUCCH resource is a first PUCCH resource of the N second PUCCH resources indicated by the PUCCH resource indication field, and when the first PUCCH resource collides with the target second PUCCH resource in the time domain, the first UCI is received through one PUCCH resource adjacent to the first PUCCH resource.

For example, as shown in fig. 2, taking the second traffic priority as a high traffic priority and the first traffic priority as a low traffic priority as an example, the first UCI includes HARQ-ACK and Channel State Information (CSI), and the second UCI includes HARQ-ACK and CSI as an example. If the PUCCH resource 1 (black filled portion in fig. 2) carrying HARQ-ACK and CSI corresponding to high traffic priority indicated by the second DCI and the PUCCH resource (diagonal filled portion in fig. 2) carrying HARQ-ACK and CSI corresponding to low traffic priority indicated by the first DCI collide in the time domain, the terminal device transmits HARQ-ACK and CSI corresponding to low traffic priority on PUCCH resource 2 (dashed box portion in fig. 2) carrying UCI corresponding to low traffic priority indicated by the second DCI, that is, the terminal device transmits UCI corresponding to high traffic priority and UCI corresponding to low traffic priority on two PUCCH resources which do not collide in the time domain, respectively. Therefore, the transmission requirement of the UCI corresponding to the high service priority can be ensured, the transmission of the UCI corresponding to the low service priority can be realized, and the problem of low resource utilization efficiency caused by discarding the UCI corresponding to the low service priority is avoided.

Further, if there is a collision in the time domain of PUCCH for transmitting multiple UCI corresponding to the same traffic priority in one time unit (e.g., one slot or one sub-slot) and resource multiplexing is allowed, the multiple UCI corresponding to the same traffic priority may multiplex PUCCH resources for transmitting HARQ-ACK of the traffic priority for transmission. For example, PUCCH resources for carrying HARQ-ACK, CSI, and Scheduling Request (SR) corresponding to the same traffic priority collide in the time domain, and then the CSI and SR are multiplexed to the PUCCH for carrying the HARQ-ACK, or the PUCCH resources for carrying the HARQ-ACK are used to carry the HARQ-ACK, CSI, and SR.

For example, as shown in fig. 3, if there is a collision in the time domain between the PUCCH resource for transmitting the HARQ-ACK corresponding to the high traffic priority and the PUCCH resource for transmitting the CSI corresponding to the high traffic priority, the PUCCH resource for transmitting the HARQ-ACK corresponding to the high traffic priority is multiplexed to transmit the CSI corresponding to the high traffic priority. Similarly, the PUCCH resource for transmitting the HAR-ACK corresponding to the low traffic priority collides with the PUCCH resource for transmitting the CSI corresponding to the low traffic priority in the time domain, and the PUCCH resource for transmitting the HARQ-ACK corresponding to the low traffic priority is multiplexed to transmit the CSI corresponding to the low traffic priority.

In general, physical layer signaling or parameters can distinguish service priorities corresponding to different UCI, and the method shown in fig. 1 further includes: and determining physical layer signaling or parameters according to a first service priority corresponding to a first UCI carried by the first PUCCH resource and a second service priority corresponding to a second UCI carried by the target second PUCCH resource.

For example, assuming that a first service priority corresponding to the first UCI is a low service priority and a second service priority corresponding to the second UCI is a high service priority, the physical layer signaling or the parameter determined by the network device may specifically be: the second DCI is DCI of a specific DCI format (or size), or the second DCI is scrambled using a specific Radio Network Temporary Identity (RNTI) (e.g., MCS-C-RNTI), or a Modulation and Coding Scheme (MCS) configured in the second DCI adopts a low spectral efficiency MCS table (MCS table index 3); the first DCI is a DCI of a DCI format other than the specific DCI format, or the first DCI is scrambled using an RNTI other than the specific RNTI, or an MCS configured in the first DCI does not use a low-frequency MCS table.

Fig. 4 is a method of information transmission according to another embodiment of the present invention, the method shown in fig. 4 being performed by a network device, as shown in fig. 4, the method including:

s210, sending first downlink control information DCI, where the first DCI indicates N first physical uplink control channel PUCCH resources used for transmitting first uplink control information UCI, where the first UCI corresponds to a first service priority, and N is a positive integer greater than or equal to 2.

S220, sending a second DCI, where the second DCI indicates a second PUCCH resource for transmitting a second UCI, and the second UCI corresponds to a second service priority.

Optionally, in some embodiments, the first traffic priority is lower than said second traffic priority. In this case, S210 and S220 may be understood as: the network equipment indicates N first PUCCH resources used for transmitting the first UCI corresponding to the low service priority for the terminal equipment through the first DCI, and indicates a second PUCCH resource for the terminal equipment through the second DCI.

It can be understood that the N first PUCCH resources indicated by the network device for the terminal device through the first DCI do not collide in the time domain. At least one of the N first PUCCH resources does not collide with the second PUCCH resource in a time domain. Or the N first PUCCH resources and the second PUCCH resources all conflict in the time domain.

That is to say, a new PUCCH resource indication manner may be defined in DCI indicating a PUCCH resource corresponding to a UCI with a low traffic priority, so that the DCI indicates N PUCCH resources that do not collide in a time domain, and the N PUCCH resources may all be used to transmit the UCI corresponding to the low traffic priority.

Optionally, in some embodiments, the first UCI includes HARQ feedback information. For example, the first UCI includes HARQ-ACK information.

S230, if a target first PUCCH resource exists in the N first PUCCH resources, receiving the first UCI through the target first PUCCH resource, and receiving the second UCI through the second PUCCH resource, where a first PUCCH resource before the target first PUCCH resource in the time domain of the N first PUCCH resources and the second PUCCH resource are both in collision in the time domain, and the target first PUCCH resource and the second PUCCH resource are not in collision in the time domain.

That is, the terminal device determines whether there is a first PUCCH resource that does not collide in the time domain with the second PUCCH resource among the N first PUCCH resources in a case where it is determined that the N first PUCCH resources indicated by the first DCI and one second PUCCH resource indicated by the second DCI, transmits the first UCI on the first PUCCH resource and transmits the second UCI on the second PUCCH resource if there is a first PUCCH resource that does not collide in the time domain with the second PUCCH resource.

Optionally, the terminal device may start to determine whether the first PUCCH resource conflicts with the second PUCCH resource in the time domain from the first PUCCH resource indicated by the PUCCH resource indication field in the DCI, and if the first PUCCH resource conflicts with the second PUCCH resource in the time domain, continue to determine whether the second first PUCCH resource conflicts with the second PUCCH resource in the time domain, in this way, until finding a first PUCCH resource that does not conflict with the second PUCCH resource in the time domain or determining that the N first PUCCH resources conflict with the second PUCCH resource in the time domain. If a first PUCCH resource can be found that does not collide with a second PUCCH resource in a time domain, the first UCI is transmitted on the first PUCCH resource, and the second UCI is transmitted on the second PUCCH resource. Correspondingly, the network device receives the first UCI on the first PUCCH resource and receives the second UCI on the second PUCCH resource. And if the first PUCCH resource and the second PUCCH resource do not conflict in the time domain, the terminal equipment sends the first UCI through the first PUCCH resource and sends the second UCI through the second PUCCH resource. Correspondingly, the network device receives the first UCI on the first PUCCH resource and receives the second UCI on the second PUCCH resource.

For example, as shown in fig. 5, the network device indicates 2 PUCCH resources for carrying UCI (HARQ-ACK) corresponding to low traffic priority to the terminal device through DCI, indicates 1 PUCCH resource for carrying UCI corresponding to high traffic priority to the terminal device through DCI, and a first PUCCH resource for carrying UCI corresponding to low traffic priority collides with a PUCCH resource for carrying UCI corresponding to high traffic priority in time domain, so that the terminal device carries UCI corresponding to low traffic priority on a second PUCCH resource for carrying UCI corresponding to low traffic priority.

Optionally, in some embodiments, the method shown in fig. 4 further includes: and if the target first PUCCH resource does not exist in the N first PUCCH resources, receiving the second UCI through the second PUCCH resource.

That is, if N first PUCCH resources all collide with the second PUCCH resource in the time domain, the terminal device transmits the second UCI only on the second PUCCH resource and discards the first UCI. In this case, if the first service priority is lower than the second service priority, the terminal device transmits only UCI corresponding to a high service priority and discards UCI corresponding to a low service priority. Therefore, the transmission requirement of the service with high service priority can be ensured.

In general, physical layer signaling or parameters can distinguish service priorities corresponding to different UCI, and the method shown in fig. 4 further includes: and determining physical layer signaling or parameters according to the first service priority corresponding to the first UCI carried by the target first PUCCH resource and the second service priority corresponding to the second UCI carried by the second PUCCH resource.

Fig. 6 is a method of information transmission according to still another embodiment of the present invention, the method shown in fig. 6 being performed by a network device, as shown in fig. 6, the method including:

s310, sending first Downlink Control Information (DCI), wherein the first DCI indicates a first Physical Uplink Control Channel (PUCCH) resource for transmitting first Uplink Control Information (UCI), and the first UCI corresponds to a first service priority;

s320, sending a second DCI, wherein the second DCI indicates a second PUCCH resource;

s330, if the first PUCCH resource and the second PUCCH resource conflict in a time domain, receiving the first UCI and the second UCI through the second PUCCH resource, wherein the second UCI corresponds to a second service priority; if the first PUCCH resource and the second PUCCH resource do not conflict in a time domain, receiving the first UCI through the first PUCCH resource and receiving the second UCI through the second PUCCH resource.

Optionally, in some embodiments, the first traffic priority is lower than said second traffic priority. In this case, S310 and S320 may be understood as: the network equipment indicates a first PUCCH resource used for transmitting a first UCI corresponding to a low service priority for the terminal equipment through the first DCI, and indicates a second PUCCH resource for the terminal equipment through the second DCI. And when the first PUCCH resource and the second PUCCH resource collide on the time domain, multiplexing the first UCI and the second UCI to transmit on the second PUCCH resource. And when the first PUCCH resource and the second PUCCH resource do not conflict in the time domain, the first UCI is transmitted on the first PUCCH resource, and the second UCI is transmitted on the second PUCCH resource. Therefore, the problem of low resource utilization rate caused by directly discarding the UCI corresponding to the low-priority service can be avoided.

As an example, in the case that the first service priority is lower than the second service priority, an indication field may be added in the second DCI or in the higher layer signaling to indicate whether the second PUCCH resource is allowed to carry UCI corresponding to the low service priority. For example, a 1-bit UCI bearer indication field is added to the second DCI, where the value of the indication field is "1" to indicate that the UCI with low traffic priority is allowed to be carried, and the value of the indication field is "0" to indicate that the UCI with low traffic priority is not allowed to be carried.

Optionally, in some embodiments, the second UCI includes hybrid automatic repeat request, HARQ, feedback information. For example, the second UCI includes HARQ-ACK information. In this case, if the first traffic priority is lower than the second traffic priority, one PUCCH resource capable of carrying multiple UCIs of different traffic priorities (low traffic priority and high traffic priority) may be indicated by DCI indicating a PUCCH resource carrying UCI corresponding to high traffic priority.

In general, physical layer signaling or parameters can distinguish service priorities corresponding to different UCI, and the method shown in fig. 6 further includes: and determining physical layer signaling or parameters according to the first service priority corresponding to the first UCI carried by the first PUCCH resource and the second service priority corresponding to the second UCI carried by the second PUCCH resource.

The method for information transmission according to the embodiment of the present invention is described in detail above from the network device side with reference to fig. 1 to 6. The method of information transmission according to an embodiment of the present invention will be described in detail from the terminal device side. It should be understood that the interaction between the network device and the terminal device described from the terminal device side is the same as that described in the network device side in the method shown in fig. 1 to 6, and the related description is appropriately omitted to avoid redundancy.

Fig. 7 is a method of information transmission according to still another embodiment of the present invention, where the method shown in fig. 7 is performed by a terminal device, and as shown in fig. 7, the method includes:

s410, receive first downlink control information DCI, where the first DCI indicates a first physical uplink control channel PUCCH resource for transmitting first uplink control information UCI, and the first UCI corresponds to a first service priority.

S420, receiving a second DCI, where the second DCI indicates N second PUCCH resources, a target second PUCCH resource of the N second PUCCH resources is used to transmit a second UCI, N-1 second PUCCH resources except the target second PUCCH resource of the second PUCCH resources are used to transmit the first UCI, the N second PUCCH resources do not collide in a time domain, the second UCI corresponds to a second service priority, and N is a positive integer greater than or equal to 2.

S430, if the first PUCCH resource collides with the target second PUCCH resource in a time domain, transmitting the first UCI through one second PUCCH resource of the N-1 second PUCCH resources, and transmitting the second UCI through the target second PUCCH resource.

Optionally, in some embodiments, the first traffic priority is lower than the second traffic priority. The network equipment defines a new PUCCH resource indication mode in DCI indicating the PUCCH resources corresponding to the UCI with the high service priority, so that the DCI indicates N non-conflicted PUCCH resources in time domain, wherein one PUCCH resource is used for transmitting the UCI corresponding to the high service priority, and the other N-1 PUCCH resources are used for transmitting the UCI corresponding to the low service priority.

Optionally, in some embodiments, the second UCI includes hybrid automatic repeat request, HARQ, feedback information. For example, the second UCI includes HARQ-ACK information.

In general, physical layer signaling or parameters can distinguish the service priority corresponding to different UCI. The method shown in fig. 7 further comprises: determining the first service priority corresponding to the first UCI carried by the first PUCCH resource and the second service priority corresponding to the second UCI carried by the target second PUCCH resource according to physical layer signaling or parameters.

For example, if the terminal device determines that the second DCI is DCI of a specific DCI format (or size), or the second DCI is scrambled using a specific RNTI (e.g., MCS-C-RNTI), or an MCS configured in the second DCI adopts a low-spectral-efficiency MCS table (MCS table index 3), the terminal device determines that the second UCI carried by the second PUCCH resource indicated by the second DCI corresponds to the second traffic priority. If the terminal equipment determines that the first DCI is a DCI of other DCI formats except the specific DCI format, or the first DCI uses other RNTIs except the specific RNTI for scrambling, or the MCS configured in the first DCI does not adopt a low-frequency MCS table, the terminal equipment determines that the first UCI carried by the target first PUCCH resource corresponds to the first service priority.

Or in other words, assuming that the first service priority is a low service priority and the second service priority is a high service priority, the UCI corresponding to the high service priority may correspond to at least one of the following:

(1) a specific DCI format;

for example, a Compact DCI different from the existing Downlink (DL) scheduling DCI payload (fallback DCI 1-0 and normal (normal) DCI 1-1) is defined, and the UCI of PUCCH resource transmission indicated by the DCI corresponds to a high traffic priority.

(2) DCI scrambled using a specific RNTI;

for example, the specific RNTI may be a modulation and coding strategy-cell radio network temporary identity (MCS-C-RNTI). The priority corresponding to the UCI of the PUCCH resource transmission indicated in the DCI scrambled by the MCS-C-RNTI is higher than the service priority corresponding to the UCI of the PUCCH resource transmission indicated in the DCI scrambled by a Cell-Radio Network Temporary Identifier (C-RNTI).

(3) The MCS in the DCI adopts a low-spectrum-efficiency MCS table (table);

the MCS table with low spectral efficiency may be MCS index table 3(MCS index table 3), and if MCS index table3 is configured in one DCI, UCI of PUCCH resource transmission indicated by the DCI corresponds to high traffic priority, which is higher than traffic priority corresponding to UCI of PUCCH resource transmission indicated by DCI using other MCS tables. The other MCS table refers to an MCS table other than the low spectral efficiency, and may be MCS index table 1 or MCS index table 2.

Further, the UCI corresponding to low traffic priority may correspond to at least one of:

(1) other DCI formats other than the specific DCI format described above;

for example, the other DCI format may be an existing DL scheduling DCI, such as: fallback DCI 1-0 and normal DCI 1-1.

(2) DCI scrambled by using RNTI except the specific RNTI;

the other RNTI may be, for example, a C-RNTI.

(3) The MCS in the DCI does not adopt an MCS table with low spectral efficiency;

for example, the DCI is configured not to employ the MCS table of low spectral efficiency but to employ other MCS tables, which may be MCS index table 1 or MCS index table 2.

Optionally, in some embodiments, at least one of the N first PUCCH resources is not in collision with the second PUCCH resource in the time domain.

Optionally, in some embodiments, the first UCI includes hybrid automatic repeat request, HARQ, feedback information.

Optionally, in some embodiments, the first traffic priority is lower than the second traffic priority.

Optionally, in some embodiments, the method shown in fig. 9 further includes: if the target first PUCCH resource does not exist in the N first PUCCH resources, the second UCI is sent through the second PUCCH resource, and the first UCI is discarded.

S720, judging whether the first PUCCH resource for bearing the UCI corresponding to the low service priority conflicts with the PUCCH resource for bearing the UCI corresponding to the high service priority in the time domain.

It should be noted that the terminal device is indicated with N PUCCH resources for carrying UCI corresponding to a low traffic priority, where N is a positive integer greater than or equal to 2.

And S730, if yes, sequentially starting from the PUCCH resource indicated by the PUCCH resource indication field of the DCI to judge whether the PUCCH resource for bearing the UCI corresponding to the low service priority conflicts with the PUCCH resource for bearing the UCI corresponding to the high service priority in the time domain.

And S760, if the conflict exists, discarding the UCI corresponding to the low service priority, and sending the UCI corresponding to the high service priority only on the PUCCH resource for bearing the UCI corresponding to the high service priority.

Optionally, in S760, if there is no collision, it is continuously determined whether the PUCCH resource for carrying the UCI corresponding to the low traffic priority collides with the PUCCH resource for carrying the UCI corresponding to the high traffic priority in the time domain.

S820, receiving a second DCI, where the second DCI indicates a second PUCCH resource.

S830, if the first PUCCH resource and the second PUCCH resource collide in a time domain, transmitting the first UCI and the second UCI through the second PUCCH resource, where the second UCI corresponds to a second service priority; and if the first PUCCH resource and the second PUCCH resource do not conflict in a time domain, transmitting the first UCI through the first PUCCH resource and transmitting the second UCI through the second PUCCH resource.

Optionally, in some embodiments, the first traffic priority is lower than said second traffic priority. In this case, S810 and S820 may be understood as: the network equipment indicates a first PUCCH resource used for transmitting a first UCI corresponding to a low service priority for the terminal equipment through the first DCI, and indicates a second PUCCH resource for the terminal equipment through the second DCI. And when the first PUCCH resource and the second PUCCH resource collide on the time domain, the first UCI and the second UCI multiplex the second PUCCH resource for transmission. And when the first PUCCH resource and the second PUCCH resource do not conflict in the time domain, the first UCI is transmitted on the first PUCCH resource, and the second UCI is transmitted on the second PUCCH resource. Therefore, the problem of low resource utilization rate caused by directly discarding the UCI corresponding to the low-priority service can be avoided.

In this case, if the first traffic priority is lower than the second traffic priority, one PUCCH resource capable of carrying multiple UCIs corresponding to different traffic priorities (low traffic priority and high traffic priority) may be indicated by DCI indicating a PUCCH resource carrying UCI corresponding to high traffic priority.

The method shown in fig. 7 further comprises: determining the first service priority corresponding to the first UCI carried by the first PUCCH resource and the second service priority corresponding to the second UCI carried by the second PUCCH resource according to physical layer signaling or parameters.

For example, if the terminal device determines that the second DCI is DCI of a specific DCI format (or size), or the second DCI is scrambled using a specific RNTI (e.g., MCS-C-RNTI), or an MCS configured in the second DCI adopts a low-spectral-efficiency MCS table (MCS table index 3), the terminal device determines that the second UCI carried by the second PUCCH resource indicated by the second DCI corresponds to the second traffic priority. If the terminal equipment determines that the first DCI is a DCI of other DCI formats except the specific DCI format, or the first DCI uses other RNTIs except the specific RNTI for scrambling, or the MCS configured in the first DCI does not adopt a low-frequency MCS table, the terminal equipment determines that the first UCI carried by the target first PUCCH resource corresponds to the first service priority. . .
