Description

Method and device for indicating occupied resources in service multiplexing scene

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for indicating occupied resources in a service multiplexing scenario.

Background

With the rapid development of mobile services, the current wireless communication technology, such as the fourth generation mobile communication technology featuring OFDM (orthogonal frequency Division Multiplexing), cannot meet the increasing demands of the scene, and researches on the fifth generation mobile communication technology (5G communication for short) are vigorously conducted in both academic circles and industrial circles.

The 5G communication needs to support an ultra-high data transmission rate, a large number of connections, and a low data transmission delay, so as to meet the requirements of different scenes. The 5G communication is mainly applicable to the following three communication scenarios: eMBBs (enhanced Mobile broadband), mMTC (massive Machine Type Communications), and URLLC (Ultra-Reliable and Low Latency Communications). The three scenarios are different in service type and service requirement, such as eMBB, enhanced mobile broadband service, mainly aiming at service scenarios requiring higher data rate, mtc, a large number of machine type communication services, mainly aiming at a large number of connected service scenarios, URLLC, high-reliability low-delay service, and mainly aiming at service scenarios requiring higher delay and having higher reliability.

For the URLLC service, due to its harsh delay requirement, when the URLLC service reaches the base station, the base station should immediately allocate resources for the URLLC service. Since most of URLLC services arrive aperiodically and sporadically, if a block of resources is reserved specially for URLLC services, a large waste of resources is caused. In order to improve the resource utilization efficiency, when a URLLC service arrives at a base station, the base station may allocate a time-frequency resource currently scheduled to an eMBB service for the URLLC service, that is, a User Equipment (UE) of the URLLC service occupies the time-frequency resource currently scheduled to the eMBB service, thereby forming a service multiplexing scenario.

Considering that after a UE of a URLLC service (URLLC UE for short) occupies a time-frequency resource of a UE of an eMBB service (eMBB UE for short), if the eMBB UE does not know which part of the resource the URLLC UE specifically occupies, data demodulation of the eMBB UE will be affected, and therefore the base station needs to indicate the occupied resource to the occupied embbe so as to facilitate the eMBB UE to perform data demodulation. When occupied resources are indicated, how to reduce signaling overhead while indicating is an urgent problem to be solved at present.

Detailed Description

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

Fig. 1 is a first flowchart of a method for indicating occupied resources in a service multiplexing scenario provided in this application, where an execution subject of the method is a base station, the base station is capable of communicating with a user terminal, and the method is applied to indicate occupied resources when a second service is occupied by a first service (including time domain resources and frequency domain resources), as shown in fig. 1, the method includes the following steps:

step S101, judging whether the length of the occupied time domain resource is less than or equal to a preset length.

When the first service reaches the base station, the base station allocates a part of the time-frequency resource currently scheduled to the second service to the first service, so that the first service occupies the time-frequency resource currently scheduled to the second service, wherein the time-frequency resource comprises a time-domain resource and a frequency-domain resource.

In this embodiment, the base station sets a preset length in advance, after the second service occupies the time domain resource by the first service, the base station determines whether the length of the occupied time domain resource is less than or equal to the preset length, if the base station determines that the length of the occupied time domain resource is less than or equal to the preset length, step S102 is executed, and if the base station determines that the length of the occupied time domain resource is greater than the preset length, step S103 is executed.

Step S102, if the length of the occupied time domain resource is less than or equal to the preset length, determining the indication granularity of the occupied time domain resource to be at a symbol level, and indicating the occupied time domain resource to the user terminal of the second service by adopting the indication granularity at the symbol level.

Wherein the indication granularity at the symbol level represents a single orthogonal frequency division multiplexing technology, OFDM, symbol indicating time domain resources.

In this step, the base station determines the indication granularity of the occupied time domain resource to be at a symbol level, and indicates the occupied time domain resource to the user terminal of the second service by using the indication granularity at the symbol level, which specifically includes: and determining the transmission time interval to which the occupied time domain resource belongs, and indicating whether each OFDM symbol in the transmission time interval is occupied or not to the user terminal of the second service through the multi-bit character in a mode that one-bit character corresponds to one OFDM symbol in the transmission time interval.

The Transmission Time Interval is a Transmission Time Interval (TTI) of the second service, and the Transmission Time Interval of the second service may include one or more slots (slots), and one slot includes 7 or 14 OFDM symbols, so the Transmission Time Interval of the second service at least includes 7 OFDM symbols. In the embodiment, the base station determines a transmission time interval to which the occupied time domain resource belongs, and after the determination, indicates whether each OFDM symbol in the transmission time interval is occupied or not to the user terminal of the second service through multi-bit characters in a manner that one-bit characters correspond to one OFDM symbol in the transmission time interval, and specifically indicates whether the corresponding OFDM symbol is occupied or not through the value of each bit character.

For example, the transmission time interval to which the time domain resource occupied by the second service belongs includes 7 OFDM symbols, where the control region occupies 1 OFDM symbol, and the control region does not need to indicate, the base station uses 6-bit characters to respectively correspond to the remaining 6 OFDM symbols, and sets "0" to indicate that the OFDM symbols are not occupied, and "1" indicates that the OFDM symbols are occupied, and the base station indicates whether the corresponding OFDM symbols are occupied through the value of each character, for example, 001000, indicates that the 3 rd OFDM symbol except the control region is occupied, and the base station further sends the character string 001000 to the ue of the second service, so that the ue of the second service knows the occupied time domain resource.

It can be understood that the number of characters required for indicating granularity at a symbol level is the same as and remains the same as the number of OFDM symbols except for the control region in the transmission time interval of the second service, and thus, the signaling overhead required for indicating granularity at a symbol level is always the number of OFDM symbols except for the control region in the transmission time interval of the second service.

Step S103, if the length of the occupied time domain resource is greater than the preset length, determining the indication granularity of the occupied time domain resource to be a micro-slot level, and indicating the occupied time domain resource to the user terminal of the second service by adopting the indication granularity of the micro-slot level.

Wherein the indication granularity of the micro-slot level indicates the length of the time domain resource and the position of the starting OFDM symbol.

In this step, if the base station determines that the length of the occupied time domain resource is greater than the preset length, the base station determines that the indication granularity of the occupied time domain resource is at a micro-slot level, and indicates the occupied time domain resource to the user terminal of the second service by using the indication granularity at the micro-slot level, where the indication granularity at the micro-slot level represents the length of the indicated time domain resource and the position of the initial OFDM symbol.

In this step, the occupied time domain resource is indicated to the user terminal of the second service by using the indication granularity at the micro-slot level, which specifically comprises: and determining the transmission time interval to which the occupied time domain resource belongs, and indicating the length of the occupied time domain resource and the position of the initial OFDM symbol of the occupied time domain resource in the transmission time interval to the user terminal of the second service. The specific explanation of the transmission time interval is as above, the length of the occupied time domain resource can be represented by the number of OFDM symbols, and the starting OFDM symbol is the first occupied OFDM symbol. For example, in the transmission time interval to which the time domain resource occupied by the second service belongs, the base station indicates to the user terminal of the second service that the length of the time domain resource occupied by the first service is 5 OFDM symbols, and the position of the initial OFDM symbol of the occupied time domain resource in the transmission time interval is the 2 nd OFDM symbol, so that in the transmission time interval to which the time domain resource occupied by the second service belongs, the first service occupies the 2 nd to 6 th OFDM symbols in the time domain.

It can be understood that, in this step, the signaling overhead required for the indication granularity at the micro-slot level is determined by the length of the time domain resource and the number of characters required for indicating the position of the starting OFDM symbol.

The signaling overhead required to compare the granularity of indication at the symbol level with the granularity of indication at the minislot level is known, when the time domain resource length occupied by the first service is longer, the signaling overhead required by the indication granularity of the micro-slot level is less than that of the indication granularity of the symbol level, when the time domain length occupied by the first service is short, for example, one OFDM symbol is occupied, the signaling overhead required for the indication granularity at the micro slot level may be greater than the indication granularity at the symbol level, so in this embodiment, the preset length is preferably the length of one OFDM symbol, therefore, when the first service occupies the length of one OFDM symbol in the time domain, the indication granularity at the symbol level is adopted for indication, and when the first service occupies the length of more than one OFDM symbol in the time domain, the indication granularity at the micro-slot level is adopted for indication, so that the signaling overhead is reduced while the indication is realized in different scenes.

As can be seen from the above technical solutions provided in the embodiments of the present application, in the method in this embodiment, when the length of the time domain resource occupied by the first service is less than or equal to the preset length, the indication granularity of the occupied time domain resource is determined to be at a symbol level, the occupied time domain resource is indicated to the user terminal of the second service by using the indication granularity at the symbol level, when the length of the time domain resource occupied by the first service is greater than the preset length, the indication granularity of the occupied time domain resource is determined to be at a micro-slot level, and the occupied time domain resource is indicated to the user terminal of the second service by using the indication granularity at the micro-slot level. The method in the embodiment of the present application can determine the indication granularity of the occupied time domain resource by distinguishing different scenes, and indicate the time domain resource occupied by the first service to the user terminal of the second service in different manners under different scenes, so that the method in the embodiment of the present application can determine the indication granularity of the occupied resource, realize the indication of the occupied resource, and achieve the technical effect of reducing signaling overhead while indicating.

Through steps S101 to S103, the indication in the time domain can be realized, fig. 2 is a second flowchart of the method for indicating occupied resources in the service multiplexing scenario provided in the embodiment of the present application, and as shown in fig. 2, the embodiment further includes step S105 to realize the indication in the frequency domain.

Step S105, dividing the frequency domain resource of the second service into a plurality of resource groups, and indicating the resource group occupied by the first service in the plurality of resource groups to the user terminal of the second service according to the frequency domain resource occupied by the first service of the second service.

The frequency domain Resource of the second service includes a plurality of Resource blocks (RBs for short), and in the frequency domain, the first service may occupy the entire bandwidth or a part of the bandwidth of the second service. If each resource block of the second service is respectively indicated to be occupied, then multi-bit characters are needed, and signaling overhead is large, so in this step, all resource blocks of the second service are grouped, and grouping needs to ensure that at least one resource group comprises a plurality of resource blocks, so that the number of groups obtained by final grouping is less than the number of resource blocks.

After grouping, the base station determines occupied resource blocks according to frequency domain resources occupied by the first service in the second service, for example, from a low frequency direction to a high frequency direction of the second service, the 3 rd to 5 th resource blocks on the frequency domain occupied by the first service in the second service. And then, the base station indicates the resource group occupied by the first service in the plurality of resource groups of the second service to the user terminal of the second service according to the occupied resource block, thereby determining the indication granularity in the frequency domain according to the frequency domain resource occupied by the first service and indicating the occupied frequency domain resource.

For example, the frequency domain resources of the second service collectively include 6 resource blocks, which are divided into two resource groups, each resource group includes 3 resource blocks, the sequence numbers of the 6 resource blocks are 1 to 6, where 1 to 3 resource blocks belong to the first resource group, and 4 to 6 resource blocks belong to the second resource group, and the base station determines that the resource blocks with sequence numbers of 4 and 5 in the second service are occupied by the first service, so that the base station indicates, to the user terminal of the second service, that the resource group occupied by the first service in the second service is the second resource group.

It should be noted that, for each resource group, as long as there is an occupied resource block for the resource group, the resource group is considered to be occupied.

It can be seen from the above that, in the frequency domain aspect, the frequency domain resources of the second service are divided into a plurality of resource groups, and the frequency domain resources occupied by the first service in the second service are indicated to the user terminal of the second service in a manner of indicating occupied resource groups.

It should be noted that, step S101 to step S103 in fig. 2 represent a time domain indicating process, step S105 represents a frequency domain indicating process, and since indicating the time domain first or indicating the frequency domain first does not affect implementation of the technical solution, fig. 2 shows an implementation sequence of indicating the time domain first and then indicating the frequency domain first, in other embodiments, step S105 may be executed first, and then step S101 and step S103 may be executed to indicate the time domain first, or step S105, step S101, and step S103 may be executed simultaneously to indicate the frequency domain and the time domain simultaneously, which is not limited in this embodiment specifically.

In the frequency domain, considering that the frequency domain resource occupied by the first service in the second service is relatively large, for example, 90% of the frequency domain resource is occupied, it may be considered that the frequency domain of the second service is completely occupied by the first service, and it is not necessary to group the frequency domain resource of the second service, therefore, in the above step S108, the frequency domain resource of the second service is divided into a plurality of resource groups, specifically, if the occupied ratio of the frequency domain resource is less than or equal to a preset threshold value, the frequency domain resource of the second service is divided into a plurality of resource groups according to a predetermined grouping parameter, where the occupied ratio of the frequency domain resource is the ratio of the size of the frequency domain resource occupied by the first service to the size of the frequency domain resource of the second service; the grouping parameter includes the number of resource groups and the difference in the maximum number of resource blocks within each resource group, or the grouping parameter includes the maximum number of resource blocks within each resource group. In this embodiment, the number of resource groups, the maximum number difference of resource blocks in each resource group, and the maximum number of resource blocks in each resource group are all configured by the base station through RRC signaling.

The grouping parameter may be configured in advance by the base station, or may be configured by an upper network side of the base station, in one case, the grouping parameter includes a number N of resource groups, and a maximum number difference i of resource blocks in each resource group, where N is a positive integer greater than or equal to 2, i is a positive integer greater than or equal to 1, for example, the frequency domain resource of the second service includes 10 resource blocks in total, and the base station configuration N is 4, i is 1, the base station may divide the 10 resource blocks into four groups, each including 3, 2, and 2 resource blocks, when the number of resource blocks included in each group is not equal, preferably, the number of resource blocks included in the resource group near the low frequency part is greater than the number of resource blocks included in the resource group near the high frequency part from the low frequency part of the frequency domain resource of the second service to the high frequency part, in this example, the number of resource blocks in the low frequency domain of the second service is from, the resource allocation is divided into 4 resource groups, and the resource groups sequentially comprise 3, 2 and 2 resource blocks. In this embodiment, it is preferable that the base station equally divides the number of resource blocks in each resource group, and when the number of resource blocks in each group cannot be equally divided, the difference between the number of resource blocks in each group is lower than or equal to the maximum number difference i. The above mentioned sequence from low frequency to high frequency may also be replaced by a sequence from high frequency to low frequency, and in the above example after the replacement, the frequency domain of the second service is divided into 4 resource groups from high frequency to low frequency, and the resource groups sequentially include 3, 2, and 2 resource blocks.

In another case, the grouping parameter includes the maximum number M of resource blocks in each resource group, where M is a positive integer greater than or equal to 2, in this case, the base station does not limit the difference between the number of resource groups and the maximum number of resource blocks in each resource group, when all resource blocks of the second service are divided into each resource group, first sequentially divide M adjacent resource blocks into one group according to a sequence from low frequency to high frequency (or a sequence from high frequency to low frequency), the same resource block is grouped only once, and when the number of remaining resource blocks is less than M, the resource blocks are grouped into one group. If the second service includes 10 resource blocks in total, and the base station configuration M value is 4, from low frequency to high frequency (or high frequency to low frequency), the first to fourth resource blocks are divided into a first resource group, the fifth to eighth resource blocks are divided into a second resource group, and the ninth and tenth resource blocks are divided into a third resource group.

After grouping all resource blocks of the second service, the base station indicates the resource group occupied by the first service in the second service to the user terminal of the second service according to the frequency domain resource occupied by the first service in the second service, thereby reducing signaling overhead and realizing frequency domain indication.

Considering that the occupied frequency domain resource is larger than the preset threshold, the method in this embodiment further includes: and if the occupied frequency domain resource is larger than the preset threshold value, determining that all the frequency domain resources of the second service are occupied by the first service, and indicating all the frequency domain resources of the second service to the user terminal of the second service.

Taking 20M bandwidth (corresponding to 100 RBs) as an example, if the occupied frequency domain resources are 95 RBs and the preset threshold is 0.9, the occupied ratio of the frequency domain resources is 0.95, and if the occupied ratio is greater than the preset threshold, the base station determines that all the frequency domain resources of the second service are occupied by the first service, and indicates all the frequency domain resources of the second service to the user terminal of the second service, so as to implement the indication of the occupied frequency domain resources.

Fig. 3 is a third flowchart illustrating a method for indicating occupied resources in a service multiplexing scenario provided in this embodiment of the present application, as shown in fig. 3, in a specific implementation manner, after step S102 and step S103, the method further includes:

step S104, judging whether the occupied frequency domain resource occupation ratio is less than or equal to a preset threshold value, if so, executing step S1051, otherwise, executing step S106.

Step S1051, dividing the frequency domain resource of the second service into a plurality of resource groups according to the predetermined grouping parameter, and indicating the resource group occupied by the first service in the plurality of resource groups to the user terminal of the second service according to the frequency domain resource occupied by the first service in the second service, wherein at least one resource group comprises a plurality of resource blocks, the grouping parameter comprises the number of the resource groups and the maximum number difference of the resource blocks in each resource group, or the grouping parameter comprises the maximum number of the resource blocks in each resource group.

It is understood that step S1051 is a specific implementation of step S105.

Step S106, determining that all frequency domain resources of the second service are occupied by the first service, and indicating all frequency domain resources of the second service to the user terminal of the second service.

In this embodiment, in the process that the base station indicates, to the user terminal of the second service, the time domain resource and the frequency domain resource occupied by the first service in the second service through the methods in fig. 1 to fig. 3, the base station further sends indication information to the user terminal of the second service, so that the user terminal of the second service knows which part of the time frequency resource is occupied by the first service, where the indication information includes time domain indication information and frequency domain indication information, the time domain indication information indicates occupied time domain resources, and the frequency domain indication information indicates occupied frequency domain resources.

Further, the base station needs to send the grouping parameters and the sequence (from low frequency to high frequency or from high frequency to low frequency) utilized in grouping to the user terminal of the second service.

In a specific application scenario, the technical solution in this embodiment is applied to a 5G communication process, where the first service is a URLLC service, and the second service is an eMBB service; in the method, the base station adopts the indication granularity at the symbol level to indicate occupied time domain resources to the user terminal of the second service through the DCI signaling, adopts the indication granularity at the micro-slot level to indicate occupied time domain resources to the user terminal of the second service through the DCI signaling, indicates the resource group occupied by the first service in the plurality of resource groups to the user terminal of the second service through the DCI signaling, and indicates all frequency domain resources of the second service to the user terminal of the second service through the DCI signaling. In a preferred embodiment, the base station indicates occupied time-frequency resources to the user equipment of the second service in the same DCI signaling. It can be understood that when the indication is performed by using DCI signaling, a part of bits of the DCI signaling need to be occupied. In this embodiment, the base station may further send the grouping parameter and the sequence used when grouping to the user equipment of the eMBB service through an RRC (Radio Resource Control) signaling.

Fig. 4 is a schematic diagram of resource currently scheduled to the eMBB service occupied by the URLLC service. In fig. 4, taking an example that a transmission time interval of the eMBB service includes 7 OFDM symbols, the service URLLC1 occupies two symbol lengths of the eMBB in the time domain and occupies a partial bandwidth of the eMBB in the frequency domain, and the service URLLC2 occupies one symbol length of the eMBB in the time domain and occupies the entire bandwidth of the eMBB in the frequency domain. It should be noted that, in the time domain, the URLLC service may occupy any symbol of the eMBB except for the control channel, and in the frequency domain, the URLLC service may occupy a part of or all of the bandwidth of the eMBB.

In fig. 4, the base station indicates the time domain resource occupied by the service URLLC1 by using the indication granularity of the micro-slot, indicates the time domain resource occupied by the service URLLC2 by using the indication granularity of the symbol level, indicates the frequency domain resource occupied by the service URLLC1 by using the method of indicating the occupied resource group, and indicates the entire bandwidth of the eMBB as the frequency domain resource occupied by the service URLLC 2.

In summary, according to the technical scheme provided by the embodiment of the application, occupied time domain resources are indicated by using symbol-level indication granularity or micro-slot-level indication granularity, occupied frequency domain resources are indicated by using a frequency domain grouping mode, occupied time frequency resources can be indicated, and signaling overhead is reduced while indication is performed.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
