Description

Full-duplex configuration method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a full duplex configuration method and apparatus.

Background

The duplex mode of the wireless communication system mainly includes two operating modes, Frequency Division Duplex (FDD) and Time Division Duplex (TDD). FDD is a method for receiving and transmitting signals on two symmetrical frequencies of the same time slot, and separating the receiving channel and the transmitting channel by a guard band. TDD is a method of receiving and transmitting signals in different time slots of the same frequency, and separating a reception channel and a transmission channel by time.

Currently, neither FDD nor TDD can support simultaneous reception and transmission of signals on the same time domain and the same frequency domain resources. To solve this problem, a full duplex technique is proposed in the industry, which can support simultaneous signal reception and signal transmission, thereby improving spectrum utilization efficiency.

However, the existing full duplex technology performs full duplex configuration for TDD or FDD respectively, and the implementation complexity is high. How to provide a full duplex configuration method suitable for both FDD and TDD is a problem that needs to be solved.

Disclosure of Invention

The embodiment of the application provides a full-duplex configuration method and device, which can be applied to existing FDD and TDD working modes, and avoid the problem of high implementation complexity caused by performing full-duplex configuration respectively for each working mode.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in one aspect, a full duplex configuration method is provided, which is applied to a base station in which a duplex mode is a Time Division Duplex (TDD) mode and/or a Frequency Division Duplex (FDD) mode, and the method includes: configuring a first single carrier F1 in at least one single carrier corresponding to the duplex mode as an uplink carrier F11 and a downlink carrier F12 corresponding to the FDD mode, where F1 ═ F11 ═ F12, F1 denotes a carrier frequency of F1, F11 denotes a carrier frequency of F11, and F12 denotes a carrier frequency of F12; the full-duplex service is provided to the UE supporting the full-duplex service according to F11, F12, and the FDD protocol. Based on the full duplex configuration method provided by the embodiment of the application, the method not only can be suitable for TDD and FDD at the same time, but also can reduce the complexity of realization and double the utilization efficiency of frequency spectrum because the existing FDD protocol can be reused.

In one possible design, before configuring a first single carrier F1 of the at least one single carrier corresponding to the duplex mode as an uplink carrier F11 and a downlink carrier F12 corresponding to the FDD mode, determining that the index parameter of the base station satisfies a preset condition; or, determining to receive a configuration indication sent by a network controller, wherein the configuration indication is used for indicating to configure the duplex mode. Due to the fact that frequency spectrum resources are limited, the base station determines that index parameters of the base station meet preset conditions or performs full duplex configuration after determining that configuration instructions sent by a network controller are received, allocation according to needs can be achieved, and the frequency spectrum resources are utilized to the maximum extent.

In one possible design, the determining that the index parameter of the base station satisfies a preset condition includes: determining that the load of the base station is not less than a first preset threshold; and/or determining that the proportion of the UE supporting the full duplex service in the UE accessing the base station is not less than a second preset threshold; and/or determining that the proportion of the UE with the data volume of the data service not less than the third preset threshold value in the UE accessing the base station as the UE supporting the full duplex service is not less than the fourth preset threshold value.

In one possible design, before configuring a first single carrier F1 of the at least one single carrier corresponding to the duplex mode as an uplink carrier F11 and a downlink carrier F12 corresponding to the FDD mode, switching the UE accessing the duplex mode from the duplex mode to another mode of the base station; or switching the UE accessing the duplex mode from the base station to other base stations. When the base station performs full duplex configuration, the base station switches the UE accessed to the duplex mode of the base station from the duplex mode to other modes of the base station, so that not only can the interruption of UE service or abnormal communication be avoided, but also key index parameters of switching cannot be influenced, and the service experience of a user is good. When the base station performs full duplex configuration, the base station switches the UE accessing the duplex mode from the base station to other base stations, so that the condition of interruption of UE service or abnormal communication can be avoided.

Because a certain number of UEs in TDD low protocol versions are still in the cell covered by the base station, and the base station in full duplex mode cannot be accessed, another carrier of FDD can be configured as a carrier of existing TDD mode, or another carrier of existing working mode that only needs one carrier. So that the base station can also serve the UEs of the low protocol version at the same time.

In one possible design, after configuring a first single carrier F1 in at least one single carrier corresponding to the duplex mode as an uplink carrier F11 and a downlink carrier F12 corresponding to the FDD mode, if the duplex mode is the FDD mode, configuring a second single carrier F2 in the at least one single carrier corresponding to the duplex mode as an uplink carrier F21 and a downlink carrier F22 corresponding to the FDD mode, where F2 ═ F21 ═ F22, F2 represents a carrier frequency of F2, F21 represents a carrier frequency of F21, and F22 represents a carrier frequency of F22; the full duplex service is provided to the UE supporting the full duplex service according to F21, F22, and the FDD protocol. The two carriers of the base station are configured as the uplink carrier and the downlink carrier corresponding to the FDD mode, so that not only can full-duplex service be provided for more users, but also the utilization efficiency of the frequency spectrum can be twice of that of the existing FDD mode.

In one possible design, the base station is a base station supporting carrier aggregation, CA, or a base station supporting multi-stream aggregation, MSA; the first single carrier F1 is the secondary carrier of the CA or the MSA. The configured carrier and the carrier of other mode are configured as the carrier of a CA system or an MSA system, so that the transmission bandwidth of the communication system can be improved. And providing better service for users.

In another aspect, an embodiment of the present application provides a full duplex configuration method, which is applied to a user equipment UE whose duplex mode is a time division duplex TDD mode and/or a frequency division duplex FDD mode, and the method includes: configuring a first single carrier F1 in at least one single carrier corresponding to the duplex mode as an uplink carrier F11 and a downlink carrier F12 corresponding to the FDD mode, where F1 ═ F11 ═ F12, F1 denotes a carrier frequency of F1, F11 denotes a carrier frequency of F11, and F12 denotes a carrier frequency of F12; base stations providing full duplex service are accessed according to F11, F12 and FDD protocols. Based on the full duplex configuration method provided by the embodiment of the application, the method not only can be suitable for TDD and FDD at the same time, but also can reduce the complexity of realization and double the utilization efficiency of frequency spectrum because the existing FDD protocol can be reused.

In one possible design, after configuring a first single carrier F1 of at least one single carrier corresponding to the duplex mode as an uplink carrier F11 and a downlink carrier F12 corresponding to the FDD mode, if the duplex mode is the FDD mode, configuring a second single carrier F2 of the at least one single carrier corresponding to the duplex mode as a carrier F3 of the TDD mode, where F2 is F3, F2 represents a carrier frequency of F2, and F3 represents a carrier frequency of F3; and accessing the base station supporting the TDD protocol according to the F3 and the TDD protocol.

Detailed Description

For ease of understanding, concepts related to the present application are first presented below.

Frequency division duplex FDD:

FDD is the reception and transmission of signals on two symmetrical frequencies in the same time slot. Fig. 1 is a schematic diagram of a conventional FDD, wherein f0-f is f-f 1. As shown in fig. 1, a certain guard band, i.e. a band guard interval, exists between f1 and f0, for example, the band guard interval of the Global System for mobile communication (GSM) in the second generation mobile communication technology is 45MHz, the band guard interval of the Wideband Code Division Multiple Access (WCDMA) in the third generation mobile communication technology is 190MHz, and the band guard interval is used to separate the receiving channel and the transmitting channel. That is, FDD must use paired frequencies, distinguish uplink channels and downlink channels according to different frequencies, and have unidirectional resources that are continuous in time and suitable for symmetric services.

Time division duplex TDD:

TDD is a method of receiving and transmitting signals in different time slots of the same frequency, and as shown in fig. 2, TDD receives and transmits signals at t1 and t0 of f0, respectively, and separates a reception channel and a transmission channel by switching time slots between uplink and downlink. That is, TDD is discontinuous in uplink and downlink in time, and time resources are allocated in both directions. And TDD can support the proportion of dynamically configuring the uplink time slot and the downlink time slot, thereby being convenient to support asymmetric services.

Full duplex technology:

since both FDD and TDD cannot support simultaneous reception and transmission of signals in the same time domain and the same frequency domain, full duplex techniques have been proposed. Full-duplex technology supports simultaneous reception and transmission of signals in the same time and frequency domain. As shown in fig. 3, when both the base station and the User Equipment (UE) support full duplex, signals can be simultaneously received and transmitted on the carrier f0 and the time slot t 0; when the base station supports full duplex and the UE supports Half duplex (FD), it is necessary for the base station to receive a signal sent by the Half-duplex UE1 at time t0 and send a signal to the Half-duplex UE2 at time t0, so as to achieve full duplex of the system.

The half-duplex in this embodiment of the present application means that at any time and at any frequency during a communication process, a signal can be transmitted from a to B and from B to a, but only transmission in one direction exists, such as FDD in fig. 1 or TDD in fig. 2.

As described in the background art, the existing full duplex technology performs full duplex configuration for TDD or FDD respectively, and the implementation complexity is high.

For example, for a TDD system, in a scenario where the UE supports half-duplex and the base station supports full-duplex, the system full-duplex can be achieved by the following method:

as shown in fig. 4, assuming that the UE0 adopts TDD matching 1, the UE1 adopts TDD matching 2, and user-level uplink and downlink matching is adopted, the base station needs to transmit and receive signals simultaneously in some subframes, for example, subframe 3 or subframe 8, UE0 is uplink, and UE1 is downlink, and the base station needs to transmit signals to UE1 and receive signals of UE0, thereby achieving system full duplex. Wherein, U represents uplink, D represents downlink, S represents uplink and downlink conversion, F subframe is full duplex subframe, downlink signal can be sent to UE1 on the subframe, and uplink signal of UE0 can be received, thereby achieving system full duplex.

Or, for example, for an FDD system, in a scenario where the UE supports half-duplex and the base station supports full-duplex, the system full-duplex may be achieved by the following method:

as shown in fig. 5, w/o indicates without, w/indicates with, HD UE w/o FS indicates that the UE is a half-duplex UE that does not support carrier Frequency switching (abbreviated as FS), HD UE w/FS indicates that the UE is a half-duplex UE that supports carrier Frequency switching, then UE1 is a half-duplex UE that supports carrier Frequency switching, and UE0 is a half-duplex UE that does not support carrier Frequency switching. That is, the UE1 may switch between uplink and downlink frequency bins. Thus, when the UE0 uses f0 as the downlink channel and f1 as the uplink channel, the UE1 can perform carrier frequency switching, uses f0 as the uplink channel and f1 as the downlink channel, so that for the base station supporting full duplex, at time t0, signals can be received and transmitted simultaneously at f0 and f1, thereby achieving system full duplex.

As shown in fig. 8, a flow chart of the full duplex configuration method provided in the embodiment of the present application is applied to a base station in which a duplex mode is a TDD mode and/or an FDD mode, and includes the following steps:

s801, the base station configures a first single carrier F1 in at least one single carrier corresponding to the duplex mode into an uplink carrier F11 and a downlink carrier F12 corresponding to the FDD mode.

Where F1 ═ F11 ═ F12, F1 denotes the carrier frequency of F1, F11 denotes the carrier frequency of F11, and F12 denotes the carrier frequency of F12.

And S802, the base station provides full-duplex service for the UE supporting the full-duplex service according to the F11, the F12 and the FDD protocol.

Specifically, the UE supporting the full duplex service in the embodiment of the present application may be an existing UE supporting the full duplex service, or may also be the UE provided in the embodiment of the present application, and this is not specifically limited in the embodiment of the present application.

Generally, the UE may obtain configuration information of the base station by monitoring broadcast information of the base station, and then identify that the base station supports a TDD duplex mode, or supports an FDD duplex mode, or supports a full duplex mode according to the configuration information of the base station. If the UE is a UE supporting the full duplex mode, the UE may directly access the base station supporting the full duplex mode.

Based on the full duplex configuration method provided by the embodiment of the application, the method not only can be suitable for TDD and FDD at the same time, but also can reduce the complexity of realization and double the utilization efficiency of frequency spectrum because the existing FDD protocol can be reused.

In one possible implementation manner, as shown in fig. 9, before step S801, step S803 may further be included:

s803, the base station determines that the index parameter of the base station meets the preset condition.

Optionally, step S803 may specifically include: and determining that the load of the base station is not less than a first preset threshold value.

Optionally, step S803 may specifically include: and the base station determines that the proportion of the UE supporting the full duplex service in the UE accessing the base station is not less than a second preset threshold value.

Optionally, step S803 may specifically include: and the base station determines that the proportion of the UE with the data volume of the data service not less than the third preset threshold value in the UE accessing the base station as the UE supporting the full duplex service is not less than the fourth preset threshold value.

It should be noted that the index parameter of the base station may be modified according to actual needs, and the threshold of the index parameter of the base station may also be changed according to actual needs. The embodiment of the present application is not particularly limited to this.

In one possible implementation manner, as shown in fig. 10, before the step S801, a step S804 may further be included:

s804, the base station determines to receive a configuration indication sent by the network controller, where the configuration indication is used to indicate to configure the duplex mode.

Specifically, the network control center operator may send the configuration indication to the base station through the network controller in case of an emergency. For example, in practical applications, if the traffic volume in a certain area is increased greatly in a short time, the operator may send a configuration instruction to the base station through the network controller according to needs, wherein the configuration instruction is used for instructing to configure the duplex mode.

Due to the fact that frequency spectrum resources are limited, the base station determines that index parameters of the base station meet preset conditions or performs full duplex configuration after determining that configuration instructions sent by a network controller are received, allocation according to needs can be achieved, and the frequency spectrum resources are utilized to the maximum extent.

In a possible implementation manner, before the step S801, the method further includes: the base station switches the UE accessing the duplex mode of the base station from the duplex mode of the base station to other modes of the base station.

In particular, other modes of operation may include any of a second generation mobile communication system, a third generation mobile communication system, a fourth generation mobile communication system, and a future communication system.

That is, generally, one base station may support multiple operation modes simultaneously, and when configuring the duplex mode of the base station, a UE accessing the base station may directly switch to the other operation modes of the base station without re-accessing other base stations.

When the base station performs full duplex configuration, the base station switches the UE accessed to the duplex mode of the base station from the duplex mode to other modes of the base station, so that not only can the interruption of UE service or abnormal communication be avoided, but also key index parameters of switching cannot be influenced, and the service experience of a user is good.

In a possible implementation manner, before the step S801, the base station further switches the UE accessing the duplex mode from the base station to another base station.

That is, in practical applications, even if there are multiple operation modes of a base station, there may be other operation modes in which the UE cannot be accessed to the base station, and when the base station needs to configure full duplex, the base station needs to switch the UE accessing the duplex mode of the base station from the base station to another base station; alternatively, in practical applications, there is also a base station with only one duplex mode, and when the base station needs to configure full duplex, the base station needs to switch the UE accessing the duplex mode of the base station from the base station to another base station.

For example, if the base station has only the TDD duplex mode, after the base station performs steps S801 and S802, if the UE in the low protocol version is a UE supporting only TDD, the UE cannot access the base station in the full duplex mode, and only can access another base station again.

Or, for example, if the base station has only the FDD duplex mode, after the base station performs steps S801 and S802, if the UE in the low protocol version is a UE supporting only FDD, the UE cannot access the base station in the full duplex mode, and only can access another base station again.

When the base station performs full duplex configuration, the base station switches the UE accessing the duplex mode from the base station to other base stations, so that the condition of interruption of UE service or abnormal communication can be avoided.

In one possible implementation, as shown in fig. 11, after step S802, steps S805 to S806 are further included:

s805, if the duplex mode of the base station is the FDD mode, configuring a second single carrier F2 of the at least one single carrier corresponding to the duplex mode as a carrier F3 of the TDD mode.

Where F2 is F3, F2 denotes a carrier frequency of F2, and F3 denotes a carrier frequency of F3.

And S806, the base station provides service for the UE supporting the TDD protocol according to the F3 and the TDD protocol.

Optionally, the UE supporting the TDD protocol may be a full-duplex UE or a half-duplex UE supporting the TDD protocol, which is not specifically limited in this embodiment of the present application.

That is, in this embodiment of the application, if the base station is in the FDD mode, after the steps S801 to S802 are executed, since a certain number of TDD low protocol versions of UEs remain in a cell covered by the base station, and the base station cannot be accessed to the full duplex mode, another carrier of the FDD may be configured as a carrier of the existing TDD mode or another carrier of the existing operating mode that only needs one carrier. So that the base station can also serve the UEs of the low protocol version at the same time.

In a possible implementation manner, after step S802, the method further includes:

if the duplex mode of the base station is the FDD mode, configuring a second single carrier F2 in the at least one single carrier corresponding to the duplex mode as an uplink carrier F21 and a downlink carrier F22 corresponding to the FDD mode. Further, the base station provides full duplex service to the UE supporting the full duplex service according to F21, F22, and the FDD protocol. Where F2 ═ F21 ═ F22, F2 denotes the carrier frequency of F2, F21 denotes the carrier frequency of F21, and F22 denotes the carrier frequency of F22.

As described above, the UE supporting the full duplex service in the embodiment of the present application may be the existing UE supporting the full duplex service, or may also be the UE provided in the embodiment of the present application, and this is not specifically limited in the embodiment of the present application.

In a possible implementation manner, the base station is a CA-supporting base station or an MSA-supporting base station, and the first single carrier F1 is a secondary carrier of the CA or the MSA.

That is, if the base station is a CA-supporting base station or an MSA-supporting base station, the base station may provide a service for the UE on the primary carrier, configure the secondary carrier as a first single carrier F1 as a UE of one uplink carrier F11 and one downlink carrier F12 corresponding to the FDD mode, where F1 is F11 is F12, F1 is a carrier frequency of F1, F11 is a carrier frequency of F11, F12 is a carrier frequency of F12, and provide a full-duplex service for the full-duplex UE according to F11, F22 and the FDD protocol.

As shown in fig. 12, a flowchart of a full duplex configuration method provided in this embodiment is applied to a UE whose duplex mode is TDD mode and/or FDD mode, and includes the following steps:

s1201, the UE configures a first single carrier F1 in at least one single carrier corresponding to the duplex mode into an uplink carrier F11 and a downlink carrier F12 corresponding to the FDD mode.

And S1202, accessing the base station providing the full duplex service according to the F11, the F12 and the FDD protocol.

Specifically, the base station providing the full duplex service in the embodiment of the present application may be an existing full duplex base station, or may also be the base station provided in the embodiment of the present application, which is not specifically limited in this application.

In one possible implementation manner, as shown in fig. 13, after step S1202, steps S1203 to S1204 may further be included:

s1203, if the duplex mode of the UE is the FDD mode, configuring a second single carrier F2 of the at least one single carrier corresponding to the duplex mode as a carrier F3 of the TDD mode.

Where F2 ═ F3, F2 denotes the carrier frequency of F2, and F3 denotes the carrier frequency of F3.

Optionally, the base station supporting the TDD protocol may be a full-duplex base station, or may also be a half-duplex base station supporting the TDD protocol, which is not specifically limited in this embodiment of the present application.

In this way, the UE can access not only the base station in full duplex mode, but also a half duplex base station supporting TDD protocol.

In one possible implementation manner, as shown in fig. 14, after step S1202, the method may further include:

if the duplex mode of the UE is the FDD mode, configuring a second single carrier F2 in the at least one single carrier corresponding to the duplex mode as an uplink carrier F21 and a downlink carrier F22 corresponding to the FDD mode. Further, the UE accesses a base station for full duplex service according to F21, F22, and the FDD protocol. Where F2 ═ F21 ═ F22, F2 denotes the carrier frequency of F2, F21 denotes the carrier frequency of F21, and F22 denotes the carrier frequency of F22.

As described above, the base station providing full duplex service in the embodiment of the present application may be an existing full duplex base station, or may also be a base station provided in the embodiment of the present application, and this is not particularly limited in this application.

Both single carriers of the UE are configured as an uplink carrier and a downlink carrier corresponding to the FDD mode, so that the UE can simultaneously support multiple services.

The following specific examples will be given in conjunction with the full-duplex configuration method described above.

Example 1, assuming that a base station supports TDD L TE 2600M, when UE covering more than 50% of the coverage of the base station is full-duplex UE, the base station needs to configure a duplex mode of the base station by using the full-duplex configuration method provided in the embodiment of the present application, as follows:

first, the base station configures a carrier F2600 MHZ to two carriers, respectively, F1 2600MHZ and F2 2600MHZ, on the TDD L TE 2600M, serving a full-duplex UE as an FDD L TE 2600M full-duplex base station according to an FDD protocol.

Secondly, the full-duplex UE accesses the FDD L TE 2600M base station according to the FDD protocol.

Example 2, assuming that the base station supports FDD L TE2100M, the uplink carrier F1 is 2000MHz, and the downlink carrier F2 is 2100MHz, when the base station determines that, in the UE accessing the base station, the data volume of the data service is not less than 50% of the UEs supporting the full-duplex service in the UEs of 5G, the base station needs to configure the duplex mode of the base station by using the full-duplex configuration method provided in the embodiment of the present application, as follows:

first, the base station configures an uplink carrier F1 as two carriers, respectively, F11-2000 MHz and F12-2000 MHz, on the FDD L TE2100M, and serves as an FDD L TE2000M full-duplex base station to the full-duplex UE according to the FDD protocol.

Secondly, the full-duplex UE accesses the FDD L TE2000M base station according to the FDD protocol.

Again, the base station may configure the downlink carrier F2 as the carrier F3 in the existing TDD duplex mode, which is 2100MHz, and serve as a TDD L TE2000M base station to serve the UE in the TDD low protocol according to the TDD protocol.

Of course, the base station may also configure the downlink carrier F2 into two carriers, respectively, F21 is 2100MHz, and F12 is 2100MHz, and then serve as an FDD L TE2100M full-duplex base station to serve the full-duplex UE according to the FDD protocol.

Example 3, suppose that the base station supports FDD L TE2100M, the uplink carrier F1 is 2000MHz, and the downlink carrier F2 is 2100MHz, when F1 of FDD L TE2100M is used as the primary carrier of the CA system, F2 is used as the secondary carrier of the CA system, the base station needs to configure F2 into two carriers, respectively, F21 is 2100MHz, and F22 is 2100 MHz.
