For example, the selection range of PUCCH resources when DC terminal equipment feeds back n-4 is the same as the selection range of PUCCH resources when FDD terminal equipment feeds back n-4. Therefore, when the FDD terminal equipment feeds back n-4 and the DC terminal equipment feeds back n-5, the selection range of PUCCH resources is different, so the PUCCH resources calculated by the DC terminal equipment and the FDD terminal equipment will be different. Therefore, the collision probability between the FDD terminal equipment and the DC terminal equipment when selecting PUCCH resources can be reduced as much as possible.

For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (Personal Digital Assistants), PDA), smart watches, smart helmets, smart glasses, smart bracelets, etc. Also includes constrained devices, such as devices with lower power consumption, or devices with limited storage capacity, or devices with limited computing power, etc. For example, information sensing devices such as barcodes, radio frequency identification (radio frequency identification, RFID), sensors, global positioning system (global positioning system, GPS), and laser scanners are included.

2) A network device, including, for example, a base station (eg, an access point), may refer to a device in an access network that communicates with a wireless terminal device over an air interface through one or more cells. The base station may be used to convert received air frames to and from Internet Protocol (IP) packets and act as a router between the terminal device and the rest of the access network, which may include the IP network. The base station may also coordinate attribute management of the air interface. For example, the base station may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in a long term evolution (long term evolution, LTE) system or an evolved LTE system (LTE-Advanced, LTE-A), or also It may include the next generation node B (next generation node B, gNB) in the fifth generation mobile communication system (5G) NR system, which is not limited in the embodiment of the present application.

3) An uplink control channel, such as a physical uplink control channel, or possibly other uplink control channels. One of the physical uplink control channels is, for example, PUCCH. For example, the uplink control channel is PUCCH, and the uplink control channel resources are PUCCH resources.

4) The terms "system" and "network" in the embodiments of this application may be used interchangeably. "Plurality" refers to two or more than two, and in view of this, "plurality" may also be understood as "at least two" in the embodiments of the present application. "And/or", which describes the association relationship of the associated objects, means that there can be three kinds of relationships, for example, A and/or B, which can mean that A exists alone, A and B exist at the same time, and B exists alone. In addition, the character "/", unless otherwise specified, generally indicates that the related objects are an "or" relationship.

Unless stated to the contrary, ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, sequence, priority, or importance of multiple objects.

The technical solutions provided in this paper can be applied to scenarios where systems supporting two radio access technologies (RATs) are deployed at the same time, such as 5G New Radio Interface (NR) systems (hereinafter referred to as NR systems) and LTE systems Simultaneous deployment, or simultaneous deployment of other two communication systems.

During the development and evolution of the wireless communication system, the NR system and the LTE system can be simultaneously deployed in the frequency band below 6 GHz. At present, the NR system is most likely to be deployed on the 3.5GHz frequency first, and the system supports terminal equipment working in the NR and LTE dual connectivity (Dual Connectivity, DC) mode, that is, the terminal equipment can work in the LTE system at the same time. and NR systems. A typical deployment method is that the NR system is deployed on a Time Division Duplex (TDD) carrier at a frequency of 3.5 GHz, while an LTE system is deployed on a Frequency Division Duplex (FDD) carrier at a frequency of 1.8 GHz.

In this deployment scenario, when the terminal device simultaneously sends uplink signals to the network device of the NR system at 3.5GHz and to the network device of the LTE system at 1.8GHz, due to the problem of cross modulation between the 3.5GHz and 1.8GHz signals , it will seriously affect the performance of the terminal equipment to receive the downlink signal of the LTE system on the 1.8GHz frequency point. In order to avoid the impact of cross-modulation on performance, and also limited by factors such as the capability and transmit power of the terminal equipment, for the terminal equipment working in the dual-connection mode of the LTE system and the NR system, it only operates at one frequency point at the same time. When the terminal device sends the uplink signal on 3.5GHz, the terminal device does not send the uplink signal on the 1.8GHz frequency, and vice versa.

At the frequency of 3.5GHz, the NR system works in the TDD mode, and the number of uplink time slots is usually less than the number of downlink time slots, which makes each uplink time slot need to be used for the terminal equipment to feed back and receive the network equipment. Acknowledgment (ACK)/Negative acknowledgment (NACK) of incoming downstream signals. At this time, since the terminal device only supports sending uplink signals on one frequency point, the terminal device cannot send signals on the uplink subframe/slot of the LTE system that overlaps with the uplink time slot of the NR system. Specifically, as shown in Fig. 1, the terminal equipment working in DC mode needs to send the ACK/NACK of the NR system in the time slots marked "U" and "S" on the NR TDD carrier, so it cannot be marked with "1". ", "2", "6", and "7" LTE subframes to send signals, which will affect the uplink performance of the LTE system. At the same time, because the terminal equipment in the LTE FDD mode adopts the N-4 ACK/NACK feedback timing, that is, the terminal equipment feeds back the ACK of the downlink data received in the downlink subframe numbered N-4 in the uplink subframe numbered N. /NACK. In the situation shown in Figure 1, the terminal equipment cannot send uplink signals on the "6" and "7" subframes on the LTE UL carrier, so the terminal equipment cannot send the uplink signal to the downlink subframe corresponding to the ACK/NACK, namely "2"" The downlink signal received on the 3" subframe is fed back, which will seriously affect the performance of the LTE system.

To this end, the network equipment in the LTE system configures a feedback timing for ACK/NACK for the terminal equipment operating in the DC mode, and the feedback timing is the same as when the terminal equipment adopts TDD-FDD carrier aggregation and the TDD carrier is the primary carrier. The feedback timing used below is the same, and the feedback timing can be shown in Table 1:

Table 1

The meaning of Table 1 can be understood as: the following line (DL)-reference (reference) uplink (UL)/DL configuration (configuration) 0 is taken as an example, the 0th subframe, the 1st subframe, the 5th subframe and the 6th subframe The frame is not used to send ACK/NACK, the 2nd subframe can feed back the ACK/NACK of the n-5th downlink subframe and the n-6th downlink subframe, and the 3rd subframe can feed back the n-4th downlink subframe and the nth downlink subframe - ACK/NACK of the 5th downlink subframe, the 4th subframe can feed back the ACK/NACK of the n-4th downlink subframe, and the 7th subframe can feed back the ACK/NACK of the n-6th downlink subframe and the n-5th downlink subframe ACK/NACK, the 8th subframe can feed back the ACK/NACK of the n-5th downlink subframe and the n-4th downlink subframe, and the 9th subframe can feed back the ACK/NACK of the n-4th downlink subframe. The so-called ACK/NACK of the downlink subframe refers to the ACK/NACK generated by the terminal device for the received downlink data after receiving the downlink data in the downlink subframe. The uplink subframe is used to send ACK/NACK to the network device.

Using this method, in the situation in FIG. 1, for example, the network equipment of the LTE system configures DL-reference UL/DL configuration 0 for the terminal equipment in DC mode (hereinafter referred to as DC terminal equipment), then the DC terminal equipment provides feedback to the LTE system. The timing can be shown in Figure 2. According to FIG. 2 , after adopting this method, downlink subframe 2 and subframe 3 of the LTE system can transmit downlink data normally, so as to avoid the loss of downlink transmission in the LTE system as much as possible. In Fig. 2, D represents a downlink subframe, U represents an uplink subframe, and S represents a special subframe.

For DC terminal equipment, since its feedback timing is the same as the feedback timing used in the case of TDD-FDD carrier aggregation and TDD carrier is the main carrier, the resources of PUCCH used by DC terminal equipment to send ACK/NACK also need to follow the appropriate method calculation.

具体的，DC终端设备的PUCCH资源计算方法可以参考第三代合作伙伴计划(3rd generation partnership project，3GPP)协议TS36.213。而对于LTE系统中工作在FDD模式下的终端设备(以下简称FDD终端设备)，其在计算PUCCH资源时也需要用到用于调度下行数据的调度信息所属的CCE的编号和

When the DC terminal device calculates the PUCCH resources, it needs to use the number and offset of the CCE to which the scheduling information for scheduling downlink data belongs.

Specifically, for the calculation method of the PUCCH resource of the DC terminal device, reference may be made to the 3rd generation partnership project (3rd generation partnership project, 3GPP) protocol TS36.213. For the terminal equipment working in the FDD mode in the LTE system (hereinafter referred to as the FDD terminal equipment), when calculating the PUCCH resources, the number and

是相同的。那么参考图3A，假如DC终端设备需要在第8上行子帧发送第2下行子帧接收的物理下行共享信道(physical downlink shared channel，PDSCH)的ACK/NACK，以及参考图3B，FDD终端设备需要在第8上行子帧发送第4下行子帧接收的PDSCH的ACK/NACK，若LTE基站在第2下行子帧调度DC终端设备接收PDSCH时所使用的CCE的编号与在第4下行子帧调度FDD终端设备接收PDSCH时所使用的CCE的编号相同，则DC终端设备计算出的PUCCH资源与FDD终端设备计算出的PUCCH资源可能就是相同的。由于一份PUCCH资源只能给一个终端设备使用，所以此时DC终端设备的PUCCH和FDD终端设备的PUCCH将发生冲突。It can be seen that although the formulas for calculating the PUCCH resources by the DC terminal equipment and the FDD terminal equipment are different, the calculation methods are related to the number of the CCE to which the scheduling information used to schedule the downlink data belongs, and the offset used is

Are the same. Then referring to FIG. 3A, if the DC terminal device needs to send the ACK/NACK of the physical downlink shared channel (PDSCH) received in the second downlink subframe in the eighth uplink subframe, and referring to FIG. 3B, the FDD terminal device needs to The ACK/NACK of the PDSCH received in the fourth downlink subframe is sent in the eighth uplink subframe, if the LTE base station schedules the CCE number used by the DC terminal equipment to receive PDSCH in the second downlink subframe and the number of the CCE used in the fourth downlink subframe scheduling The numbers of the CCEs used by the FDD terminal equipment to receive the PDSCH are the same, so the PUCCH resources calculated by the DC terminal equipment and the PUCCH resources calculated by the FDD terminal equipment may be the same. Since one PUCCH resource can only be used by one terminal device, the PUCCH of the DC terminal device and the PUCCH of the FDD terminal device will collide at this time.

In view of this, the technical solutions of the embodiments of the present application are provided to help reduce the conflict between the PUCCH of the DC terminal device and the PUCCH of the FDD terminal device, so as to avoid affecting the downlink performance of the LTE system as much as possible.

Please refer to FIG. 4 , which is a schematic diagram of an application scenario of an embodiment of the present application. Figure 4 includes two network devices and two terminal devices, wherein the network device 1 supports the first radio access technology, such as NR, and the network device 2 supports the second radio access technology, such as LTE, and the two Network devices are deployed at the same time, and terminal device 1 accesses network device 1 and network device 2 at the same time, that is, terminal device 1 works in DC mode, and terminal device 2 accesses network device 2, for example, terminal device 2 works in FDD mode. It should be noted that the network device of the LTE system and the network device of the NR system may be deployed on the same site, or may be deployed on different sites. Moreover, when it is deployed on the same site, the network device of the LTE system and the network device of the NR system can share the same set of hardware devices, or can use different hardware devices.

The network device in FIG. 4 is, for example, an access network (access network, AN) device, such as a base station, which communicates with the terminal device, receives data sent by the terminal device, and can send the received data to the core network device. Among them, because the solutions in the embodiments of the present application mainly involve access network equipment and terminal equipment, the core network equipment is not shown in FIG. 4 .

Among them, the access network equipment corresponds to different equipment in different systems. For example, in the fourth generation mobile communication technology (4G) system, it can correspond to the eNB, and in the 5G system, it corresponds to the access network equipment in 5G. The access network device currently does not have an official name, such as gNB.

That is to say, the second offset value can be understood as the offset value used by the FDD terminal device in the prior art to calculate the PUCCH resource. The first offset value is the offset value configured by the first network device for the first terminal device in the embodiment of the present application, and is not equal to the second offset value. For example, the first offset value is expressed as

It should be noted that a certain offset value described in the embodiments of the present application is used to determine the uplink control channel resources of a certain terminal equipment, because the terminal equipment uses the offset value to calculate the uplink control channel resources, and It does not mean that the offset value can only be used to determine the uplink control channel resources of the terminal device. For example, in this embodiment of the present application, the second offset value is used by the second terminal device to calculate the uplink control channel resources, so it is described that the second offset value is used to determine the uplink control channel resources of the second terminal device, and It does not mean that the first terminal device cannot use the second offset value to determine the uplink control channel resources, that is, in some cases, the first terminal device can also use the second offset value to calculate the uplink control channel resources. The offset value can then be used to determine the uplink control channel resource of the first terminal device.

In addition, if the first network device first configures the offset value for the first terminal device, the first network device may first send the offset value to the first terminal device and then configure the offset value for the second terminal device, as shown in FIG. 5 . For example, or the first network device can also configure the offset value for the second terminal device first and then send the offset value to the first terminal device, or the first network device can also configure the offset value for the second terminal device and send the offset value to the second terminal device at the same time.

Alternatively, the first indication information may also implicitly indicate that the first offset value is used to determine the uplink control channel resource of the first terminal device.

where n=0, 1, . . . , or 9.

According to Table 8 and Table 9, in the feedback sequence configured by the first network device for the first terminal device, each uplink subframe occupied by the first terminal device to send feedback information to the first network device is the same as the n-4th uplink subframe. Each downlink subframe has a corresponding relationship, so the collision probability of the uplink control channel can be reduced by this setting. The explanation is as follows:

For example, in Table 7, in TDD configuration 0, uplink subframe 0 needs to feed back ACK/NACK of downlink data in a total of 5 downlink subframes of n-4/n-5/n-6/n-7/n-8. In the prior art, when the DC terminal equipment and the DC terminal equipment feed back downlink data of different downlink subframes, the selection range of PUCCH resources is different. The selection range of the PUCCH resources that the terminal equipment feeds back n-4 is different, then the DC terminal equipment will get different PUCCH resources when feeding back downlink data of different downlink subframes, while the FDD terminal equipment and the DC terminal equipment are feeding back the same PUCCH resources. When the downlink data of the downlink subframe is used, the selection range of PUCCH resources is the same. For example, the selection range of PUCCH resources when DC terminal equipment feeds back n-4 is the same as the selection range of PUCCH resources when FDD terminal equipment feeds back n-4. Therefore, when the FDD terminal equipment feeds back n-4 and the DC terminal equipment feeds back n-5, the selection range of PUCCH resources is different, so the PUCCH resources calculated by the DC terminal equipment and the FDD terminal equipment will be different. Therefore, the collision probability between the FDD terminal equipment and the DC terminal equipment when selecting PUCCH resources can be reduced as much as possible.

S62: The first network device sends first indication information to the first terminal device, where the first indication information is used to indicate the feedback timing, and the first terminal device receives the first indication information. After receiving the first indication information, the first terminal device may determine the feedback timing according to the first indication information.

The first indication information may indicate the feedback timing through an explicit indication or an implicit indication.

In addition, according to the previous introduction, n can take an integer from 0 to 9, that is to say, n is variable, because there may be an offset between the first network device and the second network device, such as the first network device. The 0th subframe of the network device may be the second subframe for the second network device.
