Description

Measuring method and device

Technical Field

The present invention relates to the field of communications, and more particularly, to a measurement method and apparatus.

Background

In a Long Term Evolution (LTE)/LTE-Advanced (LTE-a) communication system, Frequency Division Duplex (FDD) mode and Time Division Duplex (TDD) mode may be mainly classified according to different Duplex modes.

In a wireless communication system, communications can be classified into different types according to the kinds of a transmitting node and a receiving node. Generally, sending information from a network device to a terminal device is called downlink communication, and sending information from a terminal device to a network device is called uplink communication.

For example, for a wireless communication system operating in a TDD mode, the system generally includes two carriers, one of which is used for downlink communication from a network device to a terminal device and is referred to as a downlink carrier; another carrier is used for uplink communication of the terminal device, called an uplink carrier, and the frequency of the downlink carrier is different from that of the uplink carrier. For a New air interface (New RAT, NR) in the 5G system, the network device may use an uplink and downlink decoupling technique, that is, the frequency F1 of the uplink carrier is far from the frequency F2 of the downlink carrier. For example, a typical scenario is that the downlink carrier frequency is 3.5GHz, and the frequency of the uplink carrier is 1.8GHz, in this scenario, a harmonic signal generated when the wireless device transmits a signal at the uplink carrier frequency of 1.8GHz may cause severe interference to a terminal device receiving a signal at the downlink carrier frequency of 3.5GHz, and this interference is called harmonic interference.

For another example, in both LTE and NR systems, carrier aggregation, dual connectivity and uplink Supplemental (SUL) technologies are supported, in these scenarios, a terminal device may have two or more uplink carriers for uplink communication, when the terminal device simultaneously transmits signals to a network device on two or more uplink carriers, such as the first uplink carrier frequency F1 and the second uplink carrier frequency F3, an intermodulation signal is generated on frequencies F3-F1, F3+ F1, and F3+2F1 … due to non-ideal characteristics of many modules including radio frequency modules in the communication device, and if the terminal device simultaneously receives signals on the downlink carrier frequency F2 and F2 is close to F3-F1, the intermodulation signal may seriously interfere with the performance of the terminal device receiving downlink signals on F2. For example, a typical scenario is that the first uplink carrier frequency is 1.8GHz, the second uplink carrier frequency is 3.5GHz, and the downlink carrier frequency is 1.8GHz, so that the terminal device simultaneously transmits intermodulation signals generated by uplink signals at 1.8GHz and 3.5GHz, and the intermodulation signals interfere with the performance of the terminal device for receiving downlink signals at 1.8 GHz.

Considering that when the network device schedules the terminal device to perform uplink transmission, the network device schedules a smaller number of frequency domain resource blocks, where the scheduled frequency domain resource blocks may be continuous in frequency domain or discrete in frequency domain, and the positions of the frequency domain resource blocks in the frequency band may also be flexibly changed, so that the intensity and distribution of harmonic interference/intermodulation interference caused by the transmission of the uplink signal of the terminal device to the reception of the downlink signal may be changed. That is, the harmonic interference/intermodulation interference only affects part of frequency domain resource blocks in the downlink bandwidth of the terminal device, and the terminal device can still receive downlink signals on other frequency domain resource blocks which are not interfered or have weak interference.

In order to avoid the above harmonic interference and/or intermodulation interference, usually, the terminal device does not transmit a signal on the uplink carrier when receiving the downlink signal, and the terminal device does not receive a signal on the downlink carrier when transmitting a signal on the uplink carrier. The method can cause the part of the downlink frequency domain resource block which is not interfered or is slightly interfered to be wasted, and greatly reduces the resource utilization rate of the system.

In order to solve this problem, it is necessary to clarify the interference strength of the terminal device, so as to determine the scheduling method adopted by the network device according to the interference strength.

The measuring method and the measuring device of the embodiment of the invention enable the network equipment to determine whether the terminal equipment is scheduled to send the uplink signal on the uplink carrier or not when the terminal equipment is scheduled to receive the downlink signal on the downlink carrier according to the interference intensity of the terminal equipment. Thereby improving the utilization rate of system resources.

The scheme of the embodiment of the invention is explained in detail in the following with the attached drawings of the specification.

It should be understood that the terms first, second, third, etc. may be used to describe indication information, resources and carriers in the embodiments of the present invention, but the indication information, resources and carriers should not be limited by these terms. These terms are only used to distinguish the indication information, resources and carriers from each other.

Fig. 2 is a schematic flow chart of a measurement method according to an embodiment of the present invention. As shown in fig. 2, the method includes:

201. the network equipment sends the first indication information to the terminal equipment.

Specifically, the first indication information is used to indicate a first downlink resource in at least one downlink carrier and a first uplink resource in at least one uplink carrier, where a frequency of the at least one downlink carrier is different from a frequency of the at least one uplink carrier, the first downlink resource and the first uplink resource overlap in time, and the first uplink resource is used for the terminal device to transmit a measurement signal.

It should be understood that the first downlink resource and the first uplink resource overlap in time, including: the time of the first downlink resource is completely overlapped with the time of the first uplink resource, namely the time starting point of the first downlink resource is the same as the time starting point of the first uplink resource, and the time end point of the first downlink resource is the same as the time end point of the first uplink resource; or the time of the first uplink resource may include the time of the first downlink resource, for example, the time start point of the first uplink resource is prior to the time start point of the first downlink resource, and the time end point of the first uplink resource is not prior to the time end point of the first downlink resource; or may include that the time of the first downlink resource partially overlaps with the time of the first uplink resource, for example, the time start point of the first downlink resource lags behind the time start point of the first uplink resource, and the time end point of the first downlink resource lags behind the time end point of the first uplink resource.

202. The terminal device receives the first indication information sent by the network device.

203. And the terminal equipment determines the first downlink resource and the first uplink resource according to the first indication information.

For example, the terminal device may determine the time domain resource locations of the first downlink resource and the first uplink resource according to the first indication information.

The terminal device may also receive, from the network device, third indication information in addition to the first indication information, where the third indication information is used to indicate a frequency domain resource location of the first uplink resource.

204. The network device transmits a measurement signal to the terminal device on the first downlink resource.

205. And the terminal equipment receives the measurement signal sent by the network equipment on the first downlink resource.

206. Optionally, the terminal device sends the first signal on the first uplink resource.

Illustratively, the first signal may be an uplink signal, such as a data signal, or a control signal, or an uplink measurement signal. It may also be a random signal or a predetermined signal transmitted by the terminal device, which is used only for generating harmonic signals and does not contain useful information, and which is not received by the network device.

207. Optionally, the network device receives the first signal.

208. The terminal device sends the first measurement result to the network device.

209. The network equipment receives a first measurement result sent by the terminal equipment.

The embodiment of the invention provides a measuring method and a measuring device, wherein a first downlink resource is configured for a terminal device through a network device, so that the terminal device measures interference strength on the first downlink resource and reports the interference strength to the network device, and the network device can determine whether to simultaneously schedule the terminal device to send an uplink signal on an uplink carrier when the terminal device is scheduled to receive the downlink signal on the downlink carrier according to the interference strength. For example, when the interference is strong, the network device does not schedule the terminal device to send the uplink signal on the uplink carrier at the same time when the terminal device is scheduled to receive the downlink signal on the downlink carrier, so as to avoid the interference caused by the terminal device sending the uplink signal to the downlink signal reception; for another example, when the interference is weak, the network device schedules the terminal device to transmit the uplink signal on the uplink carrier when the network device schedules the terminal device to receive the downlink signal on the downlink carrier, so that the utilization rate of the system resource is improved.

Fig. 3 is a schematic flow chart of another measurement method provided in an embodiment of the present invention, which is similar to the embodiment shown in fig. 2, except that after step 209, the method further includes:

210. and the network equipment sends second indication information to the terminal equipment.

Specifically, the second indication information is used to indicate a second downlink resource in the at least one downlink carrier and a second uplink resource of the at least one uplink carrier, where a frequency of the at least one downlink carrier is different from a frequency of the at least one uplink carrier, and the second downlink resource and the second uplink resource overlap in time.

It should be noted that the second indication information is not used for the terminal device to send the measurement signal.

For example, the second downlink resource is a resource for the network device to send a measurement signal to the terminal device, and the second uplink resource is a resource for the terminal device to be unable to send a signal. The terminal device needs to receive the measurement signal sent by the network device on the second downlink resource, but cannot send any signal on the second uplink resource, so that the terminal device does not receive a harmonic signal or an intermodulation interference signal when receiving the measurement signal, and obtains the intensity of all interference except harmonic interference through measurement.

211. The terminal equipment receives the second indication information.

212. And the terminal equipment determines the second downlink resource and the second uplink resource according to the second indication information.

213. And the network equipment sends a measurement signal to the terminal equipment on the second downlink resource.

214. The terminal device receives the measurement signal sent by the network device on the second downlink resource, and the terminal device does not send the signal on the second uplink resource.

215. And the terminal equipment sends the second measurement result to the network equipment.

Illustratively, the sending, by the terminal device, the second measurement result to the network device includes: and the terminal equipment sends a second measurement value to the network equipment, wherein the second measurement value is obtained by measuring the terminal equipment on the first downlink resource and the second downlink resource.

In this embodiment, the network device can determine, from the first measurement result, the strength of interference received by the terminal device when receiving a signal on the first downlink resource, the terminal device receives interference including an uplink signal transmitted from the terminal device, and can also determine, from the second measurement result, the strength of interference received by the terminal device when receiving a signal on the second downlink resource, the strength of interference received by the network device when receiving an uplink signal on the terminal device, the strength of interference being determined by the network device when receiving an uplink signal on the terminal device, based on the first measurement result and the second measurement result. The network device can determine whether to simultaneously schedule the terminal device to transmit the uplink signal on the uplink carrier when the terminal device is scheduled to receive the downlink signal on the downlink carrier according to the strength of the interference. When the interference is strong, the network equipment does not schedule the terminal equipment to send the uplink signal on the uplink carrier at the same time when the network equipment schedules the terminal equipment to receive the downlink signal on the downlink carrier, so that the interference of the terminal equipment for sending the uplink signal to receive the downlink signal is avoided; when the interference is weak, the network device schedules the terminal device to send the uplink signal on the uplink carrier when the network device schedules the terminal device to receive the downlink signal on the downlink carrier, so that the utilization rate of system resources is improved.

Fig. 4 is a schematic flow chart of another measurement method provided in an embodiment of the present invention, which is similar to the embodiment shown in fig. 4, except that after step 215, the method further includes:

216. the network device obtains a first measurement value according to the first measurement result and the second measurement result.

By adopting the scheme provided by the example, the network equipment can accurately determine the interference intensity of the terminal equipment for sending the uplink signal to the terminal equipment for receiving the downlink signal according to the first measurement result and the second measurement result. Furthermore, the network device can determine whether to simultaneously schedule the terminal device to transmit the uplink signal on the uplink carrier when the terminal device is scheduled to receive the downlink signal on the downlink carrier according to the strength of the interference.

206. Optionally, the terminal device sends an uplink signal on the first uplink resource.

207. Optionally, the network device receives the uplink signal.

2a, the network equipment sends second indication information to the terminal equipment.

2b, the terminal equipment receives the second indication information.

2c, the network device sends a third measurement signal to the terminal device on the second downlink resource.

2d, the terminal equipment receives the third measuring signal.

208. The terminal device sends a first measurement result corresponding to the first measurement signal and the third measurement signal to the network device, where the first measurement result is obtained by measuring the terminal device on the first downlink resource and the second downlink resource.

It should be noted that the first measurement result may be a value obtained by processing a measurement result performed by the terminal device on the first downlink resource and the second downlink resource. For example, if the result obtained by the terminal device through measurement on the first downlink resource is X1, and the result obtained by measurement on the second downlink resource is X2, the first measurement result Y may be Y ═ X1-X2, Y ═ X2-X1, Y ═ X1/X2, or Y ═ X2/X1. Of course, the first measurement result may also be the values of X1 and X2 after other arithmetic processing, and is not limited herein.

The advantageous effects of this embodiment are described with reference to the method embodiment.

The following are descriptions of the above embodiments respectively for better understanding of the solutions provided by the embodiments of the present invention:

for example, in the above embodiment, the resource unit in the first downlink resource may belong to a plurality of different frequency domain resource blocks, and the terminal device may measure each frequency domain resource block according to the resource unit and determine the measurement value. For example, the resource unit in the first downlink resource may belong to 50 different frequency domain resource blocks, and the terminal device may determine one measurement value for each frequency domain resource block, that is, 50 measurement values in total; the terminal device may also determine one measurement value for every 2 frequency domain resource blocks, that is, 25 measurement values in total; of course, the terminal device may also determine the measurement values for other frequency domain resource blocks. At this time, the measurement result will include a plurality of measurement values.

For example, in the above embodiment, the downlink carrier may be a TDD carrier or an FDD carrier; the uplink carrier may be an uplink carrier in an FDD carrier, or may also be an uplink supplemental carrier (SUL). In addition, the downlink carrier and the uplink carrier may be carriers belonging to the same radio access technology, for example, the downlink carrier and the uplink carrier are both NR carriers. The downlink carrier and the uplink carrier may also be carriers belonging to different radio access technologies, for example, the downlink carrier is a NR carrier, and the uplink carrier is an LTE carrier, or the downlink carrier is an LTE carrier and the uplink carrier is an NR carrier.

For convenience of description, in the following embodiments, the first uplink resource and the second uplink resource may be uniformly expressed by an uplink resource, the first downlink resource and the second downlink resource may be uniformly expressed by a downlink resource, and the first indication information and the second indication information may be expressed by indication information, which are only for convenience of description when the scheme is expanded.

For example, in the above embodiment, the downlink resource and the uplink resource may be time-frequency resources.

For example, in an Orthogonal Frequency Division Multiplexing (OFDM) system, the downlink resource and the uplink resource are time-frequency resource units, one or more OFDM symbols may be occupied in a time domain, the multiple OFDM symbols may be continuous or discontinuous, one or more subcarriers may be occupied in a frequency domain, and if multiple subcarriers are occupied in a frequency domain, the multiple subcarriers may be continuous or discontinuous.

For example, in the foregoing embodiment, the time domain positions of the downlink resource and the uplink resource are the same.

For example, in the above embodiment, the numbers of the time domain symbols occupied by the downlink resource and the uplink resource may be the same, that is, the same symbols in the same time slot.

For example, in the above embodiment, the subcarrier spacing of the downlink resource and the subcarrier spacing of the uplink resource may be the same or different. When the subcarrier intervals are different, the time domain symbol numbers and/or numbers occupied by the downlink resources and the uplink resources may be the same or different.

For example, when the subcarrier spacing of the downlink resource is 30KHz and the subcarrier spacing of the uplink resource is 15KHz, one possible implementation is that the downlink resource occupies the 14 th symbol of one slot, and the uplink resource occupies the 14 th symbol of one slot; in another possible implementation manner, the downlink resource occupies the 13 th symbol of one time slot, and the uplink resource occupies the 14 th symbol of one time slot; in another possible implementation manner, the downlink resource occupies two symbols, namely, the 13 th symbol and the 14 th symbol of one slot, and the uplink resource occupies the 14 th symbol of one slot.

Specifically, the downlink resource includes a first downlink resource and a second downlink resource, and the uplink resource includes a first uplink resource and a second uplink resource, a subcarrier interval of the first downlink resource and the second downlink resource is 30KHz, and a subcarrier interval of the first uplink resource and the second uplink resource is 15 KHz:

for example, the first downlink resource occupies the 14 th symbol of one slot, the first uplink resource occupies the 14 th symbol of one slot, meanwhile, the second downlink resource occupies the 14 th symbol of one slot, and the second uplink resource occupies the 14 th symbol of one slot; in another possible implementation manner, the first downlink resource occupies the 13 th symbol of one slot, the first uplink resource occupies the 14 th symbol of one slot, meanwhile, the second downlink resource occupies the 14 th symbol of one slot, and the second uplink resource occupies the 14 th symbol of one slot.

For another example, the first downlink resource occupies the 14 th symbol of one slot, the first uplink resource occupies the 14 th symbol of one slot, meanwhile, the second downlink resource occupies the 14 th symbol of one slot, and the second uplink resource occupies the 7 th symbol of one slot; in yet another possible implementation manner, the first downlink resource occupies the 13 th symbol of one time slot, the first uplink resource occupies the 14 th symbol of one time slot, meanwhile, the second downlink resource occupies the 12 th symbol of one time slot, and the second uplink resource occupies the 13 th symbol of one time slot.

It should be understood that the first downlink resource and the second downlink resource may occupy symbols with the same number in different time slots, or may occupy symbols with different numbers in the same time slot. The first uplink resource and the second uplink resource may occupy symbols with the same number in different time slots, or may occupy symbols with different numbers in the same time slot, which is not limited herein.

It should be noted that, the number of occupied symbols and the number of occupied uplink resources and downlink resources are not limited to the above embodiments, and any downlink resources and uplink resources that overlap in time belong to the protection scope of the present invention.

For example, in the above embodiment, the downlink resource and the uplink resource are both periodic resources, and the indication information may indicate a timeslot number of the downlink resource or may indicate a timeslot number of the uplink resource. For convenience of description, the following resources are taken as an example, for example, the indication information indicates the 1 st slot and the 6 th slot, that is, the downlink resources include all or part of the time-frequency resources in the 1 st slot and the 6 th slot.

It should be understood that, in the embodiment corresponding to fig. 3, the first downlink resource and the first uplink resource are periodic resources, and the second downlink resource and the second uplink resource are also periodic resources, the first indication information may indicate a slot number of the first downlink resource and may also indicate a period number of the first uplink resource, and the second indication information may indicate a slot number of the second downlink resource and may also indicate a slot number of the second uplink resource. The periods of the first downlink resource and the first uplink resource may be the same as or different from the periods of the second downlink resource and the second uplink resource. For example, the first indication information indicates the 1 st slot and the 6 th slot, and the second indication information also indicates the 1 st slot and the 6 th slot; for another example, the first indication information indicates a 1 st slot and a 6 th slot, and the second indication information indicates a 1 st slot or a 6 th slot; also for example, the first indication information indicates the 1 st slot and the 6 th slot, and the second indication information indicates the 2 nd slot.

For example, in the above embodiments, the indication information may be higher layer signaling, for example, RRC layer signaling or MAC layer signaling. The indication information may also be physical layer signaling, for example, carried in Downlink Control Information (DCI). The indication information may also be composed of two or more sub information, where a part of the sub information is carried in the higher layer signaling and sent by the network device to the terminal device, and another part of the sub information is carried in the DCI and sent by the network device to the terminal device.

In one mode, the indication information may also indicate a symbol number of the downlink resource, for example, the indication information may be used to indicate a 14 th symbol in addition to the 1 st slot and the 6 th slot, that is, the downlink resource includes a 14 th symbol in the 1 st slot and the 6 th slot.

In another way, the indication information may also indicate the number of frequency domain resource units of the downlink resource, for example, the indication information indicates the 1 st and 6 th frequency domain resource units, that is, the downlink resource includes the 1 st and 6 th frequency domain resource units of each frequency domain resource block.

It should be particularly noted that, in the above embodiment, the indication information may explicitly indicate one of the slot number, the symbol number, and the frequency domain resource unit. The indication information may also be an implicit indication, for example, the indication information may indicate a port number corresponding to the frequency domain resource unit, for example, the indication information may indicate port 0, and port 0 may correspond to 1 st, 2 nd, 7 th, and 8 th resource units in each frequency domain resource block. It should be noted that, the corresponding relationship between the port 0 and the frequency domain resource block may be predefined by a protocol, and both the network device and the terminal device obtain the corresponding relationship when leaving the factory; the corresponding relationship may be configured in advance to the terminal device by the network device. The indication information may indicate the corresponding frequency domain resource unit while indicating the port number.

For example, in the above embodiment, the downlink resource is an aperiodic resource, and in this case, the indication information may be composed of two or more pieces of sub information. One possible implementation manner is that the sub-information used for indicating the slot number in the indication information may be carried in DCI, and the sub-information used for indicating the symbol number and the frequency domain resource unit in the indication information may be carried in RRC layer signaling. Another possible implementation manner is that the sub-information used for indicating the slot number and the symbol number in the indication information is carried in DCI, and the sub-information used for indicating the frequency domain resource unit in the indication information is carried in RRC layer signaling.

It should be particularly noted that the information of the downlink resource indicated by the indication information in the above embodiments is not limited to the slot number, the symbol number, and the frequency domain resource unit number.

For example, the downlink resource is a resource for the network device to send a measurement signal to the terminal device, and the uplink resource is a resource for the terminal device to send a signal. The terminal device needs to receive the measurement signal of the network device on the downlink resource, and at the same time, the terminal device needs to transmit the signal on the uplink resource, so that the terminal device can receive the harmonic signal generated by transmitting the signal on the uplink resource when receiving the measurement signal, and obtain the strength of all interference including the harmonic interference through measurement. The signal transmitted by the terminal device on the uplink resource may be a useful data signal, a control signal, an uplink measurement signal, or the like transmitted by the terminal device to the network device, or may be a random signal or a predetermined signal transmitted by the terminal device, where the signal is used only for generating a harmonic signal and does not contain useful information, and the network device does not receive the random signal.

Illustratively, the uplink carrier may be two or more uplink carriers. In this case, the uplink resource includes resources in the two or more uplink carriers. When the terminal device receives the measurement signal of the network device on the downlink resource, the terminal and the device need to transmit a signal on the uplink resource of the two or more uplink carriers, so that the terminal device can receive the intermodulation interference generated by the transmission of the signal on the two or more uplink carriers when receiving the measurement signal, and obtain the strength of all interference including the intermodulation interference or the intermodulation interference and the harmonic interference through measurement.

For example, as described above, the uplink carrier includes the 1 st uplink carrier and the 2 nd uplink carrier, and the uplink resource includes the uplink resource on the 1 st uplink carrier and the uplink resource on the 2 nd uplink carrier, it should be noted that, when the subcarrier interval of the uplink resource on the 1 st uplink carrier is the same as the subcarrier interval of the uplink resource on the 2 nd uplink carrier, the timeslot number and the symbol number occupied by the uplink resource on the 1 st uplink carrier and the uplink resource on the 2 nd uplink carrier may be equal, so that the indication information may indicate the uplink resource on the 1 st uplink carrier and the uplink resource on the 2 nd uplink carrier at the same time. For example, the indication information includes a first field indicating the timeslot numbers of the uplink resource on the 1 st uplink carrier and the uplink resource on the 2 nd uplink carrier. When the subcarrier spacing of the uplink resource on the 1 st uplink carrier is different from the subcarrier spacing of the uplink resource on the 2 nd uplink carrier, the time slot number and/or the symbol number occupied by the uplink resource on the 1 st uplink carrier and the uplink resource on the 2 nd uplink carrier may not be equal, so that the indication information needs to indicate the time slot number and/or the symbol number of the uplink resource on the 1 st uplink carrier and the uplink resource on the 2 nd uplink carrier, respectively. For example, the indication information includes a first field indicating a slot number or a symbol number of the uplink resource on the 1 st uplink carrier and a second field indicating a slot number or a symbol number of the uplink resource on the 2 nd uplink carrier.

It should be understood that, when the subcarrier spacing of the downlink resource is equal to the subcarrier spacing of the uplink resource, and the timeslot number and/or symbol number of the downlink resource indicated by the indication information is also equal to the timeslot number and/or symbol number of the uplink resource, the indication information may indicate the timeslot number and/or symbol number of the downlink resource and the uplink resource at the same time. For example, the indication information includes a first field for indicating the slot number, and the first field indicates the slot number of the downlink resource and the uplink resource at the same time.

It should be understood that, when the subcarrier spacing of the downlink resource and the subcarrier spacing of the uplink resource are not equal, and the slot number and/or the symbol number of the downlink resource indicated by the indication information are not equal to the slot number and/or the symbol number of the uplink resource, the indication information needs to indicate the slot number and/or the symbol number of the downlink resource and the uplink resource, respectively, for example, the indication information includes a first field and a second field, where the first field is used to indicate the slot number or the symbol number of the first downlink resource, and the second field is used to indicate the slot number or the symbol number of the uplink resource.

For example, when the subcarrier spacing of the downlink resource is 30KHz, the subcarrier spacing of the uplink resource on the 1 st uplink carrier is 30KHz, and the subcarrier spacing of the uplink resource on the 2 nd uplink carrier is 15KHz, a possible implementation manner is that the downlink resource occupies the 14 th symbol of one slot, the uplink resource on the 1 st uplink carrier occupies the 14 th symbol of one slot, and the uplink resource on the 2 nd uplink carrier occupies the 14 th symbol of one slot; in another possible implementation manner, the downlink resource occupies the 13 th symbol of one time slot, the uplink resource on the 1 st uplink carrier occupies the 13 th symbol of one time slot, and the uplink resource on the 2 nd uplink carrier occupies 14 symbols of one time slot; in another possible implementation manner, the downlink resource occupies the 13 th symbol and the 14 th symbol of one slot, the uplink resource on the 1 st uplink carrier occupies the 13 th symbol and the 14 th symbol of one slot, and the uplink resource on the 2 nd uplink carrier occupies the 14 th symbol of one slot.
