Background technique

With the rapid development of communication technologies, spectrum resources have become scarce resources. At present, when a spectrum resource is allocated for a communication system of different standards, a centralized and static spectrum allocation method, that is, a fixed spectrum allocation (FSA) method, is usually adopted. In this method, one or more fixed-size spectrum resources are allocated to a specific communication technology, and the spectrum resources can be further divided for use by each operator (using the same communication system). In this way, the spectrum used by different communication systems cannot overlap, and needs to be deployed separately, and a certain interval is set, resulting in a low resource scheduling rate.

For the Long Term Evolution (LTE) system using Frequency Division Duplexing (FDD), the uplink frequency band and the downlink frequency band usually use different frequency bands, and there are between the uplink frequency band and the downlink frequency band. interval. The uplink frequency band is generally used by the terminal device to send data to the eNodeB (eNB), and the downlink frequency band is used for the eNB. The terminal device sends data. For example, the uplink frequency band is 1920 to 1940 MHz, and the terminal device transmits data to the eNB in the frequency band; the downlink frequency band is 2110 to 2130 MHz, and the eNB transmits data to the terminal device in the frequency band.

When the network is deployed, the downlink frequency band used by the LTE system is fixed. In the downlink frequency band used by the LTE system, the downlink frequency band used in the LTE system does not overlap with the spectrum resources used in the non-LTE system. ), and then determine the uplink frequency band used by the LTE system according to the set interval between the downlink frequency band and the uplink frequency band. In some areas, the uplink frequency band used by the LTE system may conflict with the frequency bands used by other standards. For example, other operators first occupy part of the frequency band for non-LTE communication technologies. In this case, In the LTE system, this entire spectrum of resources cannot be used and is wasted. To this end, the embodiment of the present invention provides a resource scheduling method, which can enable the LTE system to share the spectrum resource with the non-LTE system, that is, the LTE system can utilize the spectrum of the spectrum resource that is not occupied by the non-LTE system. Resources, thereby effectively improving the efficiency of the utilization of spectrum resources.

The non-LTE system includes, but is not limited to, Global System of Mobile communication ("GSM") system, Code Division Multiple Access ("CDMA") system, and Wideband Code Division Multiple Access. (Wideband Code Division Multiple Access, referred to as "WCDMA") system, General Packet Radio Service ("GPRS"), Universal Mobile Telecommunication System (UMTS), global Worldwide Interoperability for Microwave Access ("WiMAX") communication system.

The invention will now be described in connection with specific embodiments.

In the LTE system, the UE accesses the mobile communication network through the eNB, and the time-frequency resource is used to carry data between the eNB and the UE, thereby performing data transmission. The eNB may adopt the structure shown in FIG. 1. As shown in FIG. 1, the eNB 100 includes a memory 110, a processor 120, a transmitter 130, and a receiver 140. The eNB 100 structure illustrated in FIG. 1 does not constitute a definition of an eNB, and may include more or fewer components than those illustrated, or some components may be combined, or different component arrangements.

The processor 120 is a control center of the eNB 100, and connects various parts of the entire eNB using various interfaces and lines, and executes various kinds of the eNB 100 by running or executing a software program stored in the memory 110 and calling data stored in the memory 110. Function and processing data to provide overall control of the eNB. Alternatively, processor 120 may include one or more processing cores.

The memory 110 can be used to store various data, such as various configuration parameters, as well as to store software programs. The processor 120 executes various functional applications and data processing by running a software program stored in the memory 110. The memory 110 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system 111, an obtaining module 112, a determining module 113, a scheduling module 114, and the like; and the storage data area may store data created according to the use of the eNB 100. , for example, frequency information. In addition, the memory 110 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as Static Random Access Memory (SRAM), electrically erasable programmable read only memory. (Electrically Erasable Programmable Read-Only Memory, EEPROM for short), Erasable Programmable Read Only Memory (EPROM), Programmable Read-Only Memory (PROM), read only Read Only Memory (ROM), magnetic memory, flash memory, disk or optical disk. Accordingly, memory 110 may also include a memory controller to provide processor 120 access to memory 110.

The transmitter 130 is configured to notify the terminal device of the information of the time-frequency resource allocated to the terminal device according to the instruction of the processor 120, for example, when the physical downlink control channel (PDCCH) is allocated to the terminal device. The information of the frequency resource is sent to the terminal device, so that the terminal device transmits the data by using the allocated time-frequency resource. It is easy to know that the transmitter 130 is also used to transmit service data to the terminal device.

The receiver 140 is configured to receive data sent by the terminal device.

The eNB 100 may also include an input component 150. The input component 150 is configured to receive various configuration parameters input by the staff, for example, information of spectrum resources occupied by the non-LTE system, information of uplink spectrum resources of the LTE system, and the like. Information on spectrum resources includes, but is not limited to, center frequency and bandwidth. In addition, the input component is further configured to receive various input instructions, where the setting instructions include, but are not limited to, a multi-standard shared mode open command or a multi-system shared mode close command, and are used to indicate whether the eNB 100 uses the resource scheduling method provided by the embodiment of the present invention. The uplink scheduling of the LTE system is performed. It should be noted that the specific name of the setting instruction is not limited in the embodiment of the present invention, and other names may be used in implementation. The input component includes, but is not limited to, a human interface interface.

FIG. 2 is a flowchart of a resource scheduling method provided by an embodiment of the present invention. This embodiment is illustrated by using the method in the eNB shown in FIG. 1 . Referring to FIG. 2 , the method includes:

Step 201: Acquire information about a spectrum resource occupied by a non-LTE system, where the non-LTE system occupies The spectrum resources overlap with a portion of the uplink spectrum resources of the LTE system.

The information of the spectrum resource may include a center frequency point and a frequency bandwidth.

When implemented, the information of the spectrum resources occupied by the non-LTE system can be input and configured by the staff through the aforementioned input components, such as a human interface interface, and stored in the memory.

When the input component receives the multi-standard sharing mode on command, the processor starts to perform each step in the method, and acquires information of the spectrum resource occupied by the non-LTE system from the memory.

Step 202: Determine a spectrum resource that is not occupied by the non-LTE system in the uplink spectrum resource of the LTE standard.

The spectrum resources that are not occupied by the LTE system may be located at both ends of the uplink spectrum resource of the LTE system. For example, as shown in FIG. 3a, the unoccupied spectrum resources at both ends of the uplink spectrum resource of the LTE system are related to the uplink spectrum resources of the LTE standard. The center frequency point f0 of the uplink spectrum resource of the LTE system coincides with the center frequency point f1 of the spectrum resource occupied by the LTE system, and, for example, as shown in FIG. 3b, the uplink spectrum resource located in the LTE system The unoccupied spectrum resources at both ends are asymmetric about the center frequency of the uplink spectrum resources of the LTE system. At this time, the center frequency point f0 of the uplink spectrum resource of the LTE system does not coincide with the center frequency point f1 of the spectrum resource occupied by the LTE system. .

The spectrum resource that is not occupied by the LTE system may also be located at one end of the uplink spectrum resource of the LTE system, for example, at the high-frequency end of the uplink spectrum resource of the LTE system, as shown in FIG. 3c, or at the low-frequency end of the uplink spectrum resource of the LTE system. As shown in Figure 3d.

In an implementation manner of the embodiment of the present invention, the step 202 may include:

Determining information of downlink spectrum resources of the LTE system;

Determining information of an uplink spectrum resource of the LTE system according to information of a downlink spectrum resource of the LTE system;

The spectrum resources of the uplink spectrum resources of the LTE system that are not occupied by the non-LTE system are determined.

In this implementation, the corresponding relationship between the downlink spectrum resource and the uplink spectrum resource of the LTE system needs to be saved in the memory, for example, the interval between the center frequency of the downlink spectrum resource and the uplink spectrum resource, so that the downlink spectrum of the LTE system can be used. The information of the resource determines the information of the uplink spectrum resource of the LTE system.

In another implementation manner of the embodiment of the present invention, the information of the uplink spectrum resource of the LTE system may also be directly input by the input component and stored in the memory, where the step 202 may include:

Obtaining information of an uplink spectrum resource of the LTE standard;

Determining the uplink frequency of the LTE system according to the obtained information of the uplink spectrum resource of the LTE system Spectral resources in spectrum resources that are not occupied by non-LTE systems.

Step 203: Perform uplink scheduling in the LTE standard by using the spectrum resource that is not occupied by the non-LTE system according to the determined location of the spectrum resource that is not occupied by the non-LTE system in the uplink spectrum resource of the LTE system.

The uplink scheduling of the LTE system schedules the uplink channel and the uplink reference signal of the LTE system to the time-frequency resource allocated to the terminal device, so that the terminal device transmits data to the eNB on the allocated time-frequency resource. The uplink channel of the LTE system includes a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), and a Physical Random Access Channel (PRACH). The uplink reference signal includes a Sounding Reference Signal (SRS).

The step 203 can include:

When spectrum resources not occupied by the non-LTE system are located at both ends of the spectrum resource of the LTE standard,

Scheduling a PUCCH by using a first resource block (RB), where the first RB is an RB at both ends of the spectrum resource of the LTE system;

The second RB is used to schedule the SRS, and the second RB is the RB that is not occupied by the LTE system, and the RBs other than the first RB of all the RBs corresponding to the last symbol of each subframe;

At least one of the PUSCH and the PRACH is scheduled by using the third RB, and the third RB is an RB other than the first RB and the second RB in the spectrum resource that is not occupied by the non-LTE system.

It should be noted that when there is a PRACH that needs to be scheduled, the PRACH is preferentially scheduled, and then the remaining third RBs are used to schedule the PUSCH, that is, the PRACH and the PUSCH do not conflict with each other.

For the location of the first RB, the second RB, and the third RB, refer to FIG. 4a. However, it should be noted that only the positional relationship of the first RB, the second RB, and the third RB is shown in FIG. 4a, but It is not used to limit the number of first RBs, second RBs, and third RBs.

The number of the first RBs may be 13 to 26, and the first RB may be symmetric about the center frequency, and preferably 13 RBs at both ends of the spectrum resource of the LTE system are used as the first RB. This number is consistent with existing protocols so that it is better compatible with the terminal.

Generally, when scheduling PUCCH, it is usually located at both ends of the uplink frequency band, on the one hand, in order to obtain the largest possible frequency diversity gain, and on the other hand, to leave the frequency resource in the middle of the frequency band as much as possible to send PUSCH to other users to ensure that Get a larger peak rate.

The spectrum resources that are not occupied by the non-LTE system are located at both ends of the spectrum resource of the LTE standard. There are two cases. One case is that the center frequency of the spectrum resource of the LTE system overlaps with the center frequency of the spectrum resource of the non-LTE system, as shown in FIG. 3a, and the other case is the center frequency of the spectrum resource of the LTE system. The center frequencies of the spectrum resources of the point and non-LTE systems do not overlap, as shown in Figure 3b.

Optionally, in an implementation manner of this embodiment, the fourth RB is not scheduled to be allocated in the spectrum resource that is not occupied by the non-LTE system, and the uplink channel and the uplink reference signal are not scheduled, and the fourth RB is located in the RB of the LTE system scheduling. Between the spectrum resources occupied by the non-LTE system, the interference between the LTE system and the non-LTE system can be reduced. Alternatively, the number of fourth RBs may be, for example, five.

In an implementation manner of this embodiment, when the center frequency of the spectrum resource of the LTE system does not overlap with the center frequency of the spectrum resource of the non-LTE system, the non-LTE system is not located at the two ends of the spectrum resource of the LTE standard. When the occupied spectrum resource is asymmetric about the center frequency of the LTE system, the step 203 may include:

Determining whether the number of RBs included in the spectrum resources not occupied by the non-LTE system at both ends of the uplink spectrum resource of the LTE system is greater than a set value;

The uplink scheduling of the LTE standard is performed on the spectrum resources that are not occupied by the non-LTE system, and the spectrum resources that are not occupied by the non-LTE system, which are located at the two ends of the uplink spectrum resource of the LTE system.

That is, if the number of RBs included in the spectrum resource of the spectrum resource that is not occupied by the non-LTE system at both ends of the uplink spectrum resource of the LTE system is greater than the set value, the uplink spectrum resource located in the LTE system is used. The spectrum resources of the spectrum resources that are not occupied by the non-LTE system at the two ends are used for the uplink scheduling of the LTE system. If the spectrum resources of the spectrum resources that are not occupied by the non-LTE system at the end of the uplink spectrum resources of the LTE system are larger than the number of RBs. If the value is set, the uplink scheduling of the LTE standard is performed by using the spectrum resource that is not occupied by the non-LTE standard at the one end. The specific scheduling mode for performing uplink scheduling by using the spectrum resource of the RB whose number of RBs is greater than the set value may be used. See the case where the spectrum resource not occupied by the LTE system is located at one end of the spectrum resource of the LTE system).

When implemented, the set value can be 13 to 24 and the set value is an integer.

The step 203 can also include:

When the spectrum resource that is not occupied by the LTE system is located at one end of the spectrum resource of the LTE system, the RB scheduling PUCCH located at one end of the spectrum resource of the LTE system is used in the spectrum resource that is not occupied by the non-LTE system;

Using multiple RBs close to the PUCCH in the spectrum resources not occupied by the non-LTE system, in each The last symbol of the subframe schedules the SRS;

The remaining RBs are used to schedule the PUSCH.

The number of RBs for scheduling PUCCH is not more than 26, and may be 13 to 16; the number of RBs for scheduling PRACH may be six; the number of RBs for scheduling SRS may be 12, 96, etc., according to bandwidth, etc. Configure it. In the implementation, the SRS may be scheduled by using a frequency hopping method, or may be scheduled by using a non-frequency hopping method, which is not limited by the present invention.

Specifically, when the spectrum resource that is not occupied by the LTE standard is located at one end of the high frequency band of the spectrum resource of the LTE standard,

The RB scheduling PUCCH at one end of the high frequency band of the spectrum resource of the LTE system;

Using multiple RBs in the spectrum resource of the LTE system that are close to the PUCCH, scheduling the SRS in the last symbol of each subframe;

When the PRACH needs to be scheduled, starting from the RB where the PUCCH is located, scheduling the PRACH to multiple RBs at one end of the low frequency band;

The remaining RBs are used to schedule the PUSCH.

If the spectrum resource that is not occupied by the LTE system is located at one end of the high frequency band of the spectrum resource of the LTE system, the location of the RBs for scheduling PUCCH, PRACH, PUSCH, and SRS can be seen in FIG. 4b, but it should be noted that only FIG. 4b The positional relationship of RBs for scheduling PUCCH, PRACH, PUSCH, and SRS is shown, but is not used to limit the number of RBs for scheduling PUCCH, PRACH, PUSCH, and SRS.

Or, when the spectrum resource that is not occupied by the LTE standard is located at one end of the low frequency band of the spectrum resource of the LTE standard,

When the PRACH needs to be scheduled, starting from the RB where the PUCCH is located, scheduling the PRACH to multiple RBs at one end of the high frequency band;

The remaining RBs are used to schedule the PUSCH.

If the spectrum resource that is not occupied by the LTE system is located at one end of the low frequency band of the spectrum resource of the LTE system, the location of the RBs for scheduling PUCCH, PRACH, PUSCH, and SRS may be as shown in FIG. 4c. It should be noted that, in FIG. 4c, only the positional relationship of the RBs for scheduling PUCCH, PRACH, PUSCH, and SRS is shown, but it is not used to limit the number of RBs for scheduling PUCCH, PRACH, PUSCH, and SRS.
