Description

Resource scheduling method and device

This application claims the priority of the Chinese Patent Application, filed on Feb. 1, 2012, the entire disclosure of which is hereby incorporated by reference.

Technical field

Embodiments of the present invention relate to the field of communications and, more particularly, to methods and apparatus for resource scheduling. Background technique

The Internet of Things (IoT) refers to the acquisition of information about the physical world by deploying various devices with certain sensing, computing, execution, and communication capabilities, and realizes information transmission, coordination, and processing through the network, thereby realizing people and things. A network of objects and objects. Machine-to-machine communication (M2M) is the standard 4GPP organization. The 3GPP is the research technology and standardization concept for carrying IoT applications on the mobile communication network. At present, the enhancement or optimization of the mobile communication network is being studied for the introduction of MTC (MTC, machine type communication) equipment. Among them, providing low-cost MTC terminals based on LTE (Long Term Evolution) is a research direction. The goal is to provide an LTE terminal that can be compared to the cost of a GSM/GPRS terminal, or even lower than the cost of a GSM/GPRS terminal, to replace the application in an M2M application.

A GSM/GPRS terminal, thereby replacing the GSM/GPRS network with an LTE network in an M2M application.

A method for reducing the terminal cost by simplifying the Hybrid Automatic Repeat Request ( HARQ) mechanism is known, which is to reduce the HARQ process by completely removing the HARQ mechanism or reducing the maximum number of HARQ processes that the terminal can support. The storage space occupied, and the purpose of cost reduction is achieved.

However, completely removing the HARQ process mechanism will affect the user experience. In order to reduce the complexity of the maximum number of HARQ processes supported by the terminal, the standard tends to define only one type of UE category for low-cost LTE MTC UEs (hereinafter referred to as UEs). The UE supports the modulation level supported by the UE, thereby determining the maximum transport block size (TB size, transport block size) supported by the UE and the modulation and coding scheme that can be used. Then, if the maximum number of HARQ processes of the UE is uniformly defined, the maximum rate that all UEs can support will also be determined. However, due to the wide variety of M2M applications, the requirements for data rates are also inconsistent. For some applications, the maximum data rate determined above may not be necessary, increasing the energy consumption of the user equipment, and there is room for further cost and energy consumption reduction.

At the same time, the reduction of the number of supported maximum HARQ processes makes it impossible for the scheduling of the UE to occupy all the downlink subframes. For example, according to the existing protocol, the downlink scheduling 8 subframes is one cycle. Then, if the maximum number of HARQ processes supported by the downlink is 8, the downlink subframes have UE scheduling information. Moreover, in order to maintain the flexibility of the eNB scheduling, the eNB does not limit the resource location of the UE, so that even if the number of downlink HARQ processes actually used is less than 8, the UE is also scheduled to be scheduled in all the 8 subframes of the downlink. Therefore, the UE monitors the channel and receives the scheduling information on all downlink subframes, which increases the user equipment for the low-cost LTE MTC UE with reduced latency and data rate requirements and increased energy consumption requirements. Energy consumption, there is room for further reduction in cost and energy consumption. Summary of the invention

It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The technical solution of the embodiment of the present invention can be applied to a Long Term Evolution (LTE) system.

User (UE, User Equipment), also known as user equipment, mobile terminal (Mobile

Terminals, mobile user equipment, etc., may communicate with one or more core networks via a radio access network (eg, RAN, Radio Access Network), which may be a mobile terminal, such as a mobile phone (or "cellular") The telephone and the computer having the mobile terminal, for example, may be portable, pocket, handheld, computer built-in or in-vehicle mobile devices that exchange language and/or data with the wireless access network.

The base station may be an evolved base station (eNB or e-NodeB, E-UTRAN (Evolved Universal Terrestrial Radio Access Network) Node B) in the LTE. The embodiment of the present invention is not limited, but for convenience of description, the following embodiments The eNB is described as an example.

The network side may be an evolved packet core network (EPC, Evolved Packet Core). The embodiment of the present invention is not limited. The following embodiments are described by using an EPC as an example.

FIG. 1 shows a schematic flow chart of a method 100 for resource scheduling according to an embodiment of the present invention, which is expressed from the perspective of an eNB. As shown in FIG. 1, the method 100 includes:

S110. Determine, according to the target user, resource scheduling information, where the resource scheduling information includes information about a maximum number of HARQ processes indicating a maximum number of hybrid automatic repeat request HARQ processes that the target user can support, and/or indicating the subframe. Whether it is possible to carry a subframe of the downlink control channel Information

S120. Perform resource scheduling on the target user according to the resource scheduling information.

Specifically, before performing resource scheduling on the target user, the eNB may first obtain the resource scheduling information of the target user from the UE or the EPC, or directly determine the subframe information included in the resource scheduling information, and then send the information to the UE. Therefore, the eNB can The resource scheduling is performed on the UE according to the resource scheduling information, and the UE may receive the resource scheduling of the eNB according to the resource scheduling information. In the embodiment of the present invention, the resource scheduling information may include a maximum HARQ process number information indicating a maximum number of HARQ processes that the UE can support (hereinafter, referred to as a maximum number of HARQ processes) and/or indicating whether the subframe may be carried. Subframe information of the downlink control channel. The low-cost LTE MTC UE (hereinafter referred to as UE) defines only one type of UE category (UE category), and defines the modulation level supported by the UE, thereby determining the maximum transport block size supported by the UE ( TB size, transport block size ) and the modulation coding method that can be used. Therefore, the maximum number of HARQ processes of the UE determines the maximum rate that the UE can support. And, the UE can monitor the channel and receive the scheduling information only on the downlink subframe that is required to carry the downlink control channel according to the subframe information. Therefore, the eNB may perform different scheduling according to the content included in the resource scheduling information (the number of the HARQ processes allocated to the UE does not exceed the maximum number of HARQ processes indicated by the maximum HARQ process number information or the downlink control channel is carried in the subframe information. Corresponding subframes). Next, the case (1) in which the resource scheduling information includes the maximum HARQ process number information and the case (2) in which the resource scheduling information includes the subframe information will be described.

Situation (1)

In the embodiment of the present invention, the UE may send the resource scheduling information (for example, the maximum number of HARQ process information) to the eNB by using a specified message, and the eNB obtains the resource scheduling information by parsing the message, but when the resource is carried. The message of the scheduling information is a message that the UE transparently transmits to the EPC through the eNB (for example, the message including the attach request Attach Request), the eNB does not parse the transparent message, but directly transmits the transparent message to the EPC. In the EPC (for example, the Mobility Management Entity (MME) in the EPC, the message is parsed, and the obtained resource scheduling information is sent to the eNB. Therefore, the eNB can obtain the information by using the information reported by the UE. The maximum number of HARQ processes can also be obtained from the EPC.

Specifically, when the eNB obtains the maximum number of HARQ processes by using the information reported by the UE, At S110, the eNB may receive the first message sent by the UE, where the first message carries the maximum number of HARQ processes for indicating the maximum number of HARQ processes that the UE can support, so that the eNB may obtain the first message from the first message. The maximum number of HARQ processes is determined to determine the maximum number of HARQ processes. Therefore, in the embodiment of the present invention, the determining resource scheduling information may include:

Receiving a first message that is sent by the target user and carrying the resource scheduling information;

According to the first message, the resource scheduling information is determined.

In the embodiment of the present invention, the process of the UE reporting the maximum number of HARQ processes to the eNB may be performed in an RRC (Radio Resource Control) connection establishment procedure, a UE capability reporting procedure, or an RRC connection reconfiguration process. Therefore, the first message includes the RRC. A completion message, a user capability information message, or an RRC reconfiguration complete message is established.

It should be understood that the messages listed as the first message are merely exemplary descriptions of the present invention. Messages that other UEs may send before the resource scheduling performed by the eNB, which may be parsed by the eNB and capable of carrying resource scheduling information, are all dropped. Within the scope of protection of the present invention. The description of the same or similar cases is omitted below.

At S120, the eNB may make the number of the HARQ processes allocated to the UE not exceed the number of the maximum HARQ processes reported by the UE, so the resource scheduling for the target user includes:

The number of HARQ processes allocated to the target user is less than or equal to the maximum number of HARQ processes.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling on the target user, the number of HARQ processes allocated to the target user is less than or equal to that supported by the target user, according to the maximum number of HARQ processes reported by the target user. The maximum number of HARQ processes is not limited to the maximum rate that the UE can support. If the data rate requirements of the M2M application are inconsistent, if the maximum data rate required by the application is low, the user can reduce the number of users reported to the base station. The maximum number of HARQ processes supported, so that the maximum number of HARQ processes allocated by the base station to the user is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of the user equipment; if the maximum data rate required by the application is high, The user can increase the maximum number of HARQ processes supported by the user that is reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user is also increased, thereby increasing the maximum data rate, and is not limited to the maximum data of all users. Rate so that it can meet different Applying different data rate requirements can save costs and facilitate application support. In the embodiment of the present invention, the eNB may also save the maximum number of HARQ processes, and may record the maximum number of HARQ processes according to the relationship between the maximum number of HARQ processes reported by the UE and the user identifier of the UE, and generate a database. When the UE accesses the eNB again, for example, the UE sends an uplink data message to the EPC, or the EPC sends a downlink data message to the UE, the maximum value can be obtained from the database according to the user identifier of the UE. The number of HARQ processes. Therefore, the determining resource scheduling information further includes:

Generating a first resource scheduling information database based on the correspondence between the resource scheduling information and the user identifier of the target user;

Receiving a second message that is sent by the target user or the network side and carrying the user identifier;

And obtaining, according to the user identifier, resource scheduling information corresponding to the user identifier from the first resource scheduling information database.

In the embodiment of the present invention, the second message may be a resource request (Core Request) sent by the UE or the EPC for triggering the eNB to perform resource scheduling, for example, an RRC connection setup complete message, an RRC connection reconfiguration complete message or an initial context. Initial Context Setup Request.

It is to be understood that the above-listed messages are merely illustrative of the invention, and the invention is not limited thereto.

In this way, the resource scheduling method according to the embodiment of the present invention, except for the case of disconnecting from the network side, the UE only needs to report the maximum number of HARQ processes once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment. .

On the other hand, when the eNB acquires the maximum number of HARQ processes from the EPC, the eNB may use a bearer transmitted by the UE for a transparent message indicating the maximum number of HARQ processes of the maximum number of HARQ processes that the UE can support (eg, The attach request is forwarded to the EPC, and the EPC parses the transparent message and obtains the maximum number of HARQ processes, and then sends the maximum HARQ process information to the eNB. Therefore, the determining the resource scheduling information may include: receiving a third message that is sent by the target user and carrying the resource scheduling information;

Forwarding the third message to the network side;

Receiving a fourth message that is sent by the network side and carrying the resource scheduling information;

According to the fourth message, the resource scheduling information is determined.

In this embodiment of the present invention, the third message may be, for example, an Attach Request. The UE may send a message including the Attach Request to the eNB, for example, an RRC setup complete message, and after receiving the RRC setup complete message, the eNB does not parse the Attach Request message, but carries the Attach Request to, for example, an initial user. The information message (initial UE message) is sent to the EPC, and the fourth message may be, for example, an initial context setup request message. Therefore, the third message may be considered to be transparently transmitted to the network side, and the received network side is known. The fourth message is that the fourth message is parsed to obtain resource scheduling information.

In S120, the eNB may enable the number of HARQ processes allocated to the UE not to exceed the maximum number of HARQ processes, and therefore, performing resource scheduling on the target user includes:

The HARQ process is allocated to the target user according to the maximum number of HARQ processes, and the number of the HARQ processes is less than or equal to the maximum number of HARQ processes.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling on the target user, the number of HARQ processes allocated to the target user is less than or equal to that supported by the target user, according to the maximum number of HARQ processes reported by the target user. The maximum number of HARQ processes is not limited to the maximum rate that the UE can support. If the data rate requirements of the M2M application are inconsistent, if the maximum data rate required by the application is low, the user can reduce the number of users reported to the base station. The maximum number of HARQ processes supported, so that the maximum number of HARQ processes allocated by the base station to the user is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of the user equipment; if the maximum data rate required by the application is high, The user can increase the maximum number of HARQ processes supported by the user that is reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user is also increased, thereby increasing the maximum data rate, and is not limited to the maximum data of all users. Rate, thus Enough to meet different application requirements of different data rates, it is possible to save costs and facilitate application support.

Optionally, in the embodiment of the present invention, the EPC may further save the maximum number of HARQ processes, and may record the maximum number of HARQ processes according to the relationship between the maximum number of HARQ processes reported by the UE and the user identifier of the UE. The information, the database is generated, and when the UE accesses the service through the eNB again (for example, the EPC receives the service request sent by the eNB), the maximum HARQ can be obtained from the database according to the user identifier included in the Service Request. The number of processes, and sent to the eNB. Therefore, the determined resource scheduling information is also Can include:

And a fifth message that is sent to the network side and that carries the user identifier of the target user, where the user identifier is used by the network side to obtain the second resource scheduling information database generated from the correspondence between the resource scheduling information and the user identifier. Resource scheduling information corresponding to the user identification.

In the embodiment of the present invention, the fifth message may be a message including a service request, such as an Initial UE message. It is to be understood that the above-listed messages are merely illustrative of the invention, and the invention is not limited thereto.

In the embodiment of the present invention, the maximum number of HARQ processes may be the maximum number of HARQ processes supported by the uplink and downlink, and may include the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink), and the maximum HARQ supported by the downlink. The number of processes (Max HARQ Process Number-Downlink); more specifically, the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink) can be based on the frequency division duplex (FDD) system and the time division duplex (TDD) system. Divided into the maximum number of HARQ processes supported by the FDD system (Max HARQ Process Number-Uplink-FDD), the maximum number of HARQ processes supported by the TDD system (Max HARQ Process Number-Uplink-TDD); the maximum number of HARQ processes supported by the downlink (Max HARQ Process Number-Downlink) can be divided into FDD and TDD, the maximum number of HARQ processes supported by the FDD system (Max HARQ Process Number-Downlink-FDD), and the maximum number of HARQ processes supported by the TDD system (Max HARQ) Process Number-Downlink-TDD ).

Therefore, the maximum number of HARQ processes includes the maximum number of uplink HARQ processes, the maximum number of downlink HARQ processes, the maximum number of HARQ processes in the frequency division duplex FDD system, the maximum number of HARQ processes in the time division duplex TDD system, and the maximum number of HARQ processes in the FDD system. The number of maximum HARQ processes in the TDD system.

In this way, the flexibility of resource scheduling is further increased.

Situation ( 2 )

In the embodiment of the present invention, the UE may send the resource scheduling information (for example, the subframe information used to indicate whether the subframe may carry the downlink control channel) to the eNB, and the eNB passes the eNB. After the message is parsed, the resource scheduling information is obtained. However, when the message carrying the resource scheduling information is a message that the UE transparently transmits to the EPC through the eNB (for example, a message including an Attach Request), the eNB does not transparently transmit the message. The message is parsed, but is directly transmitted to the EPC. In this case, the message can be parsed in the EPC (for example, the MME in the EPC), and the obtained resource scheduling information is sent to the eNB. Therefore, the eNB can The subframe information is obtained by using the information reported by the UE, and the subframe information may also be obtained from the EPC. Moreover, the eNB may also determine the subframe information by itself and then notify the UE.

Specifically, when the eNB obtains the subframe information by using the information reported by the UE, the eNB may receive the first message sent by the UE, where the first message carries the subframe information of the subframe that the UE wants to monitor. Therefore, the eNB may obtain the subframe information from the first message. Therefore, in the embodiment of the present invention, the determining the resource scheduling information may include:

Specifically, the UE may report the subframe information of the subframe that it wishes to listen to the downlink control channel in the form of a bitmap. Taking FDD as an example, an 8-bit bitmap can be used to indicate that it wants to listen to the subframe information of the downlink control channel. The corresponding bit of the bitmap is 1, indicating that the UE wants to listen to the downlink channel in the corresponding subframe, and the corresponding bit of the bitmap is 0, indicating the UE. It is not desirable to listen to the downstream channel on the corresponding subframe.

In the embodiment of the present invention, the process of reporting the subframe information by the UE to the eNB may be performed in an RRC connection establishment procedure, a UE capability reporting procedure, or an RRC connection reconfiguration process. Therefore, the first message includes an RRC setup complete message and user capability. Information message or RRC reconfiguration complete message.

At S120, the eNB may carry the downlink control channel in the subframe corresponding to the subframe information, so that the UE can listen to the downlink control channel only in the subframe corresponding to the subframe information, and on other subframes. Select sleep, so the resource scheduling for the target user includes:

And according to the subframe information, the downlink control channel is carried in a subframe corresponding to the subframe information. In this way, according to the resource scheduling method of the embodiment of the present invention, when performing resource scheduling on the target user, the base station carries the downlink control channel to the subframe that the target user wants to monitor according to the subframe information reported by the target user, so that the target user can be enabled. The downlink control channel is only monitored in the specified subframe, and sleep is selected in other subframes, so that the UE does not need to listen to the channel in all downlink subframes, and receives scheduling information. This is a low-cost LTE with reduced latency and data rate requirements and increased energy consumption requirements. For MTC UEs, energy consumption is reduced, thereby reducing the cost of user equipment.

Optionally, in the embodiment of the present invention, the eNB may further save the subframe information, and may record the subframe information according to a relationship between the subframe information reported by the UE and the user identifier of the UE, and generate the subframe information. The database, when the UE accesses the eNB again for service access (for example, the UE sends an uplink data packet to the EPC, or the EPC sends a downlink data packet to the UE), the database may be obtained from the database according to the user identifier of the UE. Subframe information. Therefore, the determining resource scheduling information further includes:

In this way, the resource scheduling method according to the embodiment of the present invention, in addition to the disconnection with the network side, the UE only needs to report the subframe information once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment.

On the other hand, when the eNB acquires the subframe information from the EPC, the eNB may send, by the UE, a transparent transmission message (for example, Attach Request) that is sent by the UE to indicate whether the subframe may carry the downlink control channel. Forwarding to the EPC, the EPC parses the transparent message, and after acquiring the subframe information, sends the subframe information to the eNB. Therefore, the determining resource scheduling information may include:

Receiving a third message that is sent by the target user and carrying the resource scheduling information;

Forwarding the third message to the network side;

In the embodiment of the present invention, the third message may be, for example, an Attach Request, and the UE may send a message including the Attach Request to the eNB, for example, an RRC setup complete message, and after receiving the RRC setup complete message, the eNB does not parse the Attach Request. The message is sent to the EPC by, for example, carrying the Attach Request (for carrying resource scheduling information), for example, an Initial UE message, and the fourth message may be, for example, an Initial Context Setup Request.

At S120, the eNB may carry the downlink control channel in a subframe corresponding to the subframe information, Therefore, the UE can listen to the downlink control channel only in the subframe corresponding to the subframe information carried in the first message sent by the eNB, and select sleep on the other subframes, so the resource scheduling for the target user includes:

And according to the subframe information, the downlink control channel is carried in a subframe corresponding to the subframe information. In this way, according to the resource scheduling method of the embodiment of the present invention, when performing resource scheduling on the target user, the base station carries the downlink control channel to the subframe that the target user wants to monitor according to the subframe information reported by the target user, so that the target user can be enabled. The downlink control channel is only monitored in the specified subframe, and sleep is selected in other subframes, so that the UE does not need to listen to the channel in all downlink subframes, and receives scheduling information. This reduces power consumption and reduces the cost of user equipment for low-cost LTE MTC UEs with reduced latency and data rate requirements and increased energy consumption requirements.

Optionally, in the embodiment of the present invention, the EPC may further save the subframe information, and may record the subframe information according to a relationship between the subframe information reported by the UE and the user identifier of the UE, and generate a database. The UE performs the service access again. For example, when the EPC receives the service request (Service Request) sent by the UE, the EPC can directly obtain the subframe information from the database according to the user identifier included in the Service Request, and send the subframe information to the UE. eNB. Therefore, the determining resource scheduling information may further include:

And a fifth message that is sent to the network side and that carries the user identifier of the target user, where the user identifier is used by the network side to obtain the second resource scheduling information database generated from the correspondence between the resource scheduling information and the user identifier. Resource scheduling information corresponding to the user identification. In the embodiment of the present invention, the fifth message may be a message including a Service Request, such as an Initial UE message.

In the above embodiment, the user identifier may include a mobile user mobile number (MSISDN,

Mobile Subscriber Integrated Services Digital Network), International Mobile Station Equipment Identity (IMSI), International Mobile Station Identity (IMEI), Globally Unique Temporary Identifier (GUTI), and At least one of the Temporary Mobile Subscriber Identifier (TMSI). It should be understood that the above enumerated The information as the user identification is merely an exemplary description of the present invention, and other information capable of uniquely representing the user equipment in the network falls within the scope of the present invention. The description of the same or similar cases is omitted below.

When the eNB informs the UE after determining the subframe information, the eNB determines the subframe information by itself according to the flexibility of the UE2 delay and the data rate requirement according to the flexibility of the requirements and the scheduling. Therefore, the determining resource scheduling information includes:

Determining the subframe information;

Sending a sixth message carrying the subframe information to the target user, where the subframe corresponding to the subframe information is used by the target user to listen to the downlink control channel.

In the embodiment of the present invention, the process of the eNB transmitting the subframe information to the UE may be performed in the RRC connection reconfiguration process. Therefore, the sixth message may include an RRC reconfiguration complete message. It is to be understood that the above-listed messages are merely illustrative of the invention, and the invention is not limited thereto.

At S120, the eNB may carry the downlink control channel in a subframe corresponding to the subframe information, and the UE may listen to the downlink control channel only in the subframe corresponding to the subframe information, and select sleep in other subframes. Therefore, the resource scheduling for the target user includes:

And according to the subframe information, the downlink control channel is carried in a subframe corresponding to the subframe information. In this manner, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling on the target user, the base station sends the downlink control channel to the subframe corresponding to the subframe information by sending the subframe information to the target user. The target user can listen to the downlink control channel only in the specified subframe, and select sleep in other subframes, so that the UE does not need to listen to the channel in all downlink subframes, and receives scheduling information. For low-cost LTE MTC UEs with reduced latency and data rate requirements and increased energy consumption requirements, energy consumption is reduced, thereby reducing the cost of user equipment.

It should be understood that in the practice of the present invention, the term "and/or" herein is merely an association describing the associated object, indicating that there may be three relationships, for example, A and / or B, which may represent: A exists separately There are three cases of A and B, and B alone. In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship. That is, the resource scheduling information may include only the maximum number of HARQ processes or subframe information to implement the technical effects expressed in the above case (1) or case (2), and may also include all of the two (1) and The two technical effects expressed in case (2). Hereinafter, the description of the same or similar cases will be omitted.

2 illustrates a method 200 of resource scheduling in accordance with an embodiment of the present invention, as expressed from a UE perspective. Schematic flow chart. As shown in FIG. 2, the method 200 includes:

S210. Determine resource scheduling information, where the resource scheduling information includes a maximum number of HARQ processes for indicating a maximum number of hybrid automatic repeat request HARQ processes that the target user can support, and/or indicating whether the subframe may carry downlink control. Subframe information of the channel;

S220. Accept resource scheduling of the base station according to the resource scheduling information.

In addition, in the embodiment of the present invention, the resource scheduling information may include a maximum hybrid automatic repeat request HARQ process number of the UE and/or subframe information used to indicate whether the subframe may carry the downlink control channel.

Specifically, the UE may report the resource scheduling information to the eNB or the EPC, so that the eNB performs resource scheduling according to the resource scheduling information. Moreover, when the resource scheduling information is the subframe information, the eNB may determine the subframe information and send the subframe information to the UE, so that the UE monitors the downlink control channel in the specified subframe according to the subframe. In the embodiment of the present invention, the resource scheduling information may include a maximum number of HARQ processes for indicating the maximum number of HARQ processes that the UE can support (hereinafter, referred to as the maximum number of HARQ processes) and/or indicating whether the subframe may be carried. Subframe information of the downlink control channel. Since only one type of UE class is defined for the UE, the modulation level supported by the UE is limited, thereby determining the maximum TB size supported by the UE and the modulation and coding mode that can be used. Therefore, the maximum number of HARQ processes that the UE can support determines the maximum rate that the UE can support. And, the UE can monitor the channel and receive the scheduling information only on the downlink subframe that is required to carry the downlink control channel according to the subframe information. Therefore, the eNB may perform different scheduling according to the content included in the resource scheduling information (the number of the HARQ processes allocated to the UE does not exceed the maximum number of HARQ processes indicated by the maximum number of HARQ processes or the downlink control channel is carried in the subframe information. Corresponding subframes). The following describes the case (3) of the resource scheduling information including the maximum HARQ process information that the UE can support, and the case where the resource scheduling information includes the subframe information (4).

Situation (3)

In the embodiment of the present invention, the UE sends the resource scheduling information (for example, the maximum number of HARQ process information) to the eNB, and the eNB obtains the resource scheduling information by parsing the message, but when the resource scheduling is performed, When the message of the information is transmitted by the UE to the EPC through the eNB (for example, the message including the Attach Request), the eNB does not parse the transparent message, but directly transmits it to the EPC. In this case, In EPC (for example, in EPC) The MME analyzes the message and sends the obtained resource scheduling information to the eNB. Therefore, the UE may report the maximum number of HARQ processes to the eNB, or report the information to the EPC.

Specifically, when the UE reports the maximum number of HARQ processes to the eNB, the UE may determine the maximum number of HARQ processes that the UE can support, and send a first message to the eNB, where the first message carries The maximum number of HARQ processes of the maximum number of HARQ processes, so that the eNB can obtain the maximum number of HARQ processes supported by the UE from the first message, thereby determining the maximum number of HARQ processes. Therefore, in the embodiment of the present invention, The method also includes:

And transmitting, by the base station, a first message carrying the resource scheduling information, to notify the base station to perform resource scheduling according to the resource scheduling information.

In the embodiment of the present invention, the process of the UE reporting the maximum number of HARQ processes to the eNB may be performed in an RRC connection setup procedure, a UE capability reporting procedure, or an RRC connection reconfiguration process. Therefore, the first message includes an RRC setup complete message, and the user Capability information message or RRC reconfiguration complete message.

In S220, the resource scheduling performed by the eNB is that the maximum number of HARQ processes allocated by the eNB to the UE does not exceed the maximum number of HARQ processes reported by the UE. Therefore, the resource scheduling of the receiving base station according to the resource scheduling information includes:

The HARQ process allocated by the base station according to the maximum number of HARQ processes is configured, and the number of the HARQ processes is less than or equal to the maximum number of HARQ processes. In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling on the target user, the number of HARQ processes allocated to the target user is less than or equal to that supported by the target user, according to the maximum number of HARQ processes reported by the target user. The maximum number of HARQ processes is not limited to the maximum rate that the UE can support. If the data rate requirements of the M2M application are inconsistent, if the maximum data rate required by the application is low, the user can reduce the number of users reported to the base station. The maximum number of HARQ processes supported, so that the maximum number of HARQ processes allocated by the base station to the user is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of the user equipment; if the maximum data rate required by the application is high, The user can increase the maximum number of HARQ processes supported by the user that is reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user is also increased, thereby increasing the maximum data rate, and is not limited to the maximum data of all users. Rate, which can satisfy With different application requirements for data rates, cost savings and facilitate application support. In the embodiment of the present invention, the eNB may also save the maximum number of HARQ processes, and may record the maximum number of HARQ processes according to the relationship between the maximum number of HARQ processes reported by the UE and the user identifier of the UE, and generate a database. When the UE accesses the eNB again, for example, the UE sends an uplink data message to the EPC, or the EPC sends a downlink data message to the UE, the maximum value can be obtained from the database according to the user identifier of the UE. The number of HARQ processes. Therefore, the method further includes:

Sending, by the base station, a second message carrying a user identifier, where the user identifier is used by the base station to obtain, according to the first resource scheduling information database generated according to the correspondence between the resource scheduling information and the user identifier, the user identifier corresponding to the user identifier. Resource scheduling information.

In this embodiment of the present invention, the second message may be a Resource Request that is sent by the UE to the eNB to trigger resource scheduling of the eNB, for example, an RRC connection setup complete message, and an RRC connection reconfiguration complete message. It is to be understood that the above-described respective messages are merely illustrative of the present invention, and the present invention is not limited thereto.

On the other hand, when the UE reports the maximum number of HARQ processes to the EPC, the UE may carry a transparent transmission message (for example, the maximum number of HARQ processes indicating the maximum number of HARQ processes that the UE can support by the eNB through the eNB (for example, The attached request is sent to the EPC, and the EPC sends the maximum number of HARQ processes to the eNB after parsing the transparent message and obtaining the maximum number of HARQ processes. Therefore, the method further includes:

The third message carrying the resource scheduling information is sent to the network side to indicate that the network side sends the resource scheduling information to the base station.

In this embodiment, the third message may be, for example, an Attach Request. In this case, the UE may send a message including the Attach Request to the eNB, for example, an RRC setup complete message, and after receiving the RRC setup complete message, the eNB does not The Attach Request message included therein is parsed, and the Attach Request (bearer resource scheduling information) is carried to the EPC, for example, by the Initial UE message. It should be understood that the above-listed messages are merely illustrative of the invention, and the invention is not limited thereto.

At S220, the resource scheduling performed by the eNB accepted by the UE is the HARQ allocated by the eNB to the UE. The maximum number of processes does not exceed the maximum number of HARQ processes reported by the UE.

Optionally, in the embodiment of the present invention, the EPC may further save the maximum number of HARQ processes, and may record the maximum number of HARQ processes according to the relationship between the maximum number of HARQ processes reported by the UE and the user identifier of the UE. The information is generated, and when the UE accesses the service through the eNB again (for example, the EPC receives the Service Request sent by the eNB), the maximum value can be obtained from the database according to the user identifier included in the Service Request.

The number of HARQ processes is sent to the eNB. Therefore, the method can further include:

Transmitting, to the network side, a fourth message carrying a user identifier, where the user identifier is used by the network side to obtain, from the second resource scheduling information database generated according to the correspondence between the resource scheduling information and the user identifier, the user identifier Corresponding resource scheduling information.

In this embodiment of the present invention, the fourth message may be a Service Request message. It is to be understood that the above-listed messages are merely illustrative of the invention, and the invention is not limited thereto.

In this way, the resource scheduling method according to the embodiment of the present invention, in addition to the disconnection with the network side, the UE only needs to report the maximum number of HARQ processes once, which can further reduce the energy consumption of the UE during communication and reduce the cost of the user equipment. .

In the embodiment of the present invention, the maximum number of HARQ processes may be the maximum number of HARQ processes supported by the uplink and downlink, and may include the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink), and the maximum HARQ supported by the downlink. Number of processes (Max More specifically, the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink) can be divided into frequency division duplex (FDD) systems and time division duplex (TDD) systems, FDD The maximum number of HARQ processes supported by the system (Max HARQ Process Number-Uplink-FDD), the maximum number of HARQ processes supported by the TDD system (Max HARQ Process Number-Uplink-TDD); The maximum number of HARQ processes supported by the downlink (Max HARQ Process) Number-Downlink can be divided into FDD and TDD, the maximum number of HARQ processes supported by the FDD system (Max HARQ Process Number-Downlink-FDD), and the maximum number of HARQ processes supported by the TDD system (Max HARQ Process Number-Downlink) -TDD).

Therefore, the maximum number of HARQ processes includes the maximum number of uplink HARQ processes and the maximum downlink.

The number of HARQ processes, the number of maximum HARQ processes in the FDD system, the maximum number of HARQ processes in the TDD system, the maximum number of HARQ processes in the FDD system, and the maximum number of HARQ processes in the TDD system.

In this way, the flexibility of resource scheduling is further increased.

Situation (4)

In the embodiment of the present invention, the UE may send the resource scheduling information (for example, the subframe information used to indicate whether the subframe may carry the downlink control channel) to the eNB, and the eNB obtains the message by parsing the message. The resource scheduling information, but when the message carrying the resource scheduling information is a message that the UE transparently transmits to the EPC through the eNB (for example, a message including an Attach Request), the eNB does not parse the transparent message, but directly It is transparently transmitted to the EPC. In this case, the message can be parsed in the EPC (for example, the MME in the EPC), and the obtained resource scheduling information is sent to the eNB. Therefore, the UE can report the subframe information to the eNB. The UE may also be reported to the EPC, and the UE may also acquire the subframe information from the eNB.

Specifically, when the UE reports the subframe information to the eNB, the UE may send a first message to the eNB, where the first message carries subframe information that represents a subframe that the UE wants to listen to, so that the eNB may Obtaining the subframe information from the first message, therefore, in the embodiment of the present invention, the method further includes:

Specifically, the UE may report in the form of a bitmap to indicate that it wishes to listen to the downlink. Subframe information of a subframe of a control channel. Taking FDD as an example, an 8-bit bitmap can be used to indicate that it wants to listen to the subframe information of the downlink control channel. The corresponding bit of the bitmap is 1, indicating that the UE wants to listen to the downlink channel in the corresponding subframe, and the corresponding bit of the bitmap is 0, indicating the UE. It is not desirable to listen to the downstream channel on the corresponding subframe.

In the embodiment of the present invention, the process of reporting the maximum number of HARQ processes by the UE to the eNB may be

The RRC connection establishment process, the UE capability reporting process, or the RRC connection reconfiguration process is performed. Therefore, the first message includes an RRC setup complete message, a user capability information message, or an RRC reconfiguration complete message.

The eNB may carry the downlink control channel in the subframe corresponding to the subframe information, so that in S220, the UE may listen to the downlink control channel only in the subframe corresponding to the subframe information, and select the downlink control channel in other subframes. Sleeping, so the resource scheduling performed by the base station according to the resource scheduling information includes:

Based on the subframe information, the downlink control channel is monitored on a subframe corresponding to the subframe information.

In this way, according to the resource scheduling method of the embodiment of the present invention, when performing resource scheduling on the target user, the base station carries the downlink control channel to the subframe that the target user wants to monitor according to the subframe information reported by the target user, so that the target user can be enabled. The downlink control channel is only monitored in the specified subframe, and sleep is selected in other subframes, so that the UE does not need to listen to the channel in all downlink subframes, and receives scheduling information. This reduces power consumption and reduces the cost of user equipment for low-cost LTE MTC UEs with reduced latency and data rate requirements and increased energy consumption requirements.

Optionally, in the embodiment of the present invention, the eNB may further save the subframe information, and may record the subframe information according to a relationship between the subframe information reported by the UE and the user identifier of the UE, and generate the subframe information. The database, when the UE accesses the eNB again for service access (for example, the UE sends an uplink data packet to the EPC, or the EPC sends a downlink data packet to the UE), the database may be obtained from the database according to the user identifier of the UE. Subframe information. Therefore, the method further includes:

In this embodiment of the present invention, the second message may be a Resource Request that is sent by the UE to the eNB to trigger resource scheduling of the eNB, for example, an RRC connection setup complete message, and the RRC connection is heavy. Configuration completion message.

On the other hand, when the UE reports the subframe information to the EPC, the UE may carry a transparent transmission message (for example, an attach request message) by using the eNB to carry subframe information indicating whether the subframe may carry the downlink control channel. The EPC transparently transmits the packet to the EPC, and the EPC parses the transparent message, and after acquiring the subframe information, sends the subframe information to the eNB. Therefore, the method may further include: sending a third message carrying the resource scheduling information to the network side, to indicate that the network side sends the resource scheduling information to the base station.

In this embodiment, the third message may be, for example, an Attach Request. In this case, the UE may send a message including the Attach Request to the eNB, for example, an RRC setup complete message, and after receiving the RRC setup complete message, the eNB does not The Attach Request message included therein is parsed, and the Attach Request (bearer resource scheduling information) is carried to the EPC, for example, by the Initial UE message.

The eNB may carry the downlink control channel in the subframe corresponding to the subframe information, so that in S220, the UE may monitor the downlink control only in the subframe corresponding to the subframe information carried in the first message sent by the eNB to the eNB. The channel is selected to sleep on other subframes, so the resource scheduling performed by the base station according to the resource scheduling information includes:

Optionally, in the embodiment of the present invention, the EPC may further save the subframe information, and may record the subframe information according to a relationship between the subframe information reported by the UE and the user identifier of the UE, and generate a database. The UE accesses the service again through the EPC (for example, the EPC receives the eNB. When the service request (Service Request) is sent, the sub-frame information is obtained from the database and sent to the eNB according to the user identifier included in the Service Request of the UE. Therefore, the method can further include:

Transmitting, to the network side, a fourth message carrying a user identifier, where the user identifier is used by the network side to obtain, from the second resource scheduling information database generated based on the correspondence between the resource scheduling information and the user identifier, the user identifier Corresponding resource scheduling information.

In this embodiment of the present invention, the fourth message may be a Service Request message.

When the UE acquires the subframe information from the eNB, the eNB determines the subframe information by itself according to the requirements and the flexibility of the scheduling, and the UE receives the sub-frame information sent by the eNB. Frame information. Therefore, the determining resource scheduling information includes:

Receiving a fifth message that is sent by the base station and carrying the subframe information;

According to the fifth message, the subframe information is determined.

At S120, the UE may listen to the downlink control channel only in the subframe corresponding to the subframe information, and select sleep on other subframes. Therefore, resource scheduling for the target user includes:

In this manner, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling on the target user, the base station sends the downlink control channel to the subframe corresponding to the subframe information by sending the subframe information to the target user. The target user can listen to the downlink control channel only in the specified subframe, and select sleep in other subframes, so that the UE does not need to listen to the channel in all downlink subframes, and receives scheduling information. For low-cost LTE MTC UEs with reduced latency and data rate requirements and increased energy consumption requirements, energy consumption is reduced, thereby reducing the cost of user equipment.

FIG. 3 shows a schematic flow chart of a method 300 for resource scheduling according to an embodiment of the present invention, expressed from the perspective of an EPC. As shown in FIG. 3, the method 300 includes: S310. Receive a first message that carries the resource scheduling information that is sent by the target user, where the resource scheduling information includes information about a maximum number of HARQ processes for indicating a maximum number of hybrid automatic repeat request HARQ processes that the target user can support, and/or Subframe information indicating whether a subframe may carry a downlink control channel;

S320. Determine, according to the first message, the resource scheduling information.

S330. Send a second message carrying the resource scheduling information to the base station, to notify the base station to perform resource scheduling on the target user according to the resource scheduling information.

In addition, in the embodiment of the present invention, the resource scheduling information may include a maximum number of HARQ process information indicating a maximum number of HARQ processes that the UE can support, and/or subframe information indicating whether a subframe may carry a downlink control channel. .

Specifically, in S310, the EPC may receive a first message (for example, an Attach Request) sent by the UE, where the first message carries resource scheduling information of the UE (including maximum HARQ process number information and/or subframe information). ).

At S320, the EPC may obtain the resource scheduling information from the first message by parsing the first message. In S330, the EPC may send a second message carrying the resource scheduling information to the eNB, so that the eNB acquires the resource scheduling information, and performs resource scheduling on the target user according to the resource scheduling information (for example, the HARQ process allocated to the UE). The maximum number of times is less than or equal to the maximum number of HARQ processes, and/or the downlink control channel is carried in a subframe corresponding to the subframe information.

In the embodiment of the present invention, the first message may be, for example, an Attach Request, and the UE may send a message including the Attach Request, for example, an RRC setup complete message, to the eNB, after receiving the RRC setup complete message, the eNB receives the RRC setup complete message. The Attach Request message is not parsed, and the Attach Request is sent to the EPC, for example, an Initial UE message, and the second message may be, for example, an Initial Context Setup Request message. . It is to be understood that the above-listed messages are merely illustrative of the invention, and the invention is not limited thereto.

In this way, according to the resource scheduling method of the embodiment of the present invention, when the base station performs resource scheduling on the target user, the number of HARQ processes allocated to the target user is less than or equal to that supported by the target user, according to the maximum number of HARQ processes reported by the target user. The maximum number of HARQ processes is not limited to the maximum rate that the UE can support. If the data rate requirements of the M2M application are inconsistent, if the maximum data rate required by the application is low, the user can reduce the reporting to the base station. The maximum number of HARQ processes supported by the user, so that the maximum number of HARQ processes allocated by the base station to the user is also reduced, thereby reducing the maximum data rate, thereby reducing the cost of the user equipment; if the maximum data rate required by the application is lower If the value is high, the user can increase the maximum number of HARQ processes supported by the user that is reported to the base station, so that the maximum number of HARQ processes allocated by the base station to the user is also increased, thereby increasing the maximum data rate, and is not limited to all users. The maximum data rate, which can meet the different data rate requirements of different applications, can save costs and facilitate application support. In addition, when performing resource scheduling on the target user, the base station carries the downlink control channel to the subframe that the target user wants to monitor according to the subframe information reported by the target user, so that the target user can only listen to the downlink control channel in the specified subframe. The sleep is selected on other subframes, so that the UE does not need to listen to the channel on all downlink subframes, and receives scheduling information. This reduces power consumption and reduces the cost of user equipment for low-cost LTE MTC UEs with reduced latency and data rate requirements and increased energy consumption requirements.

Optionally, in the embodiment of the present invention, the EPC may further save the maximum number of HARQ processes, and may record the maximum number of HARQ processes according to the relationship between the maximum number of HARQ processes reported by the UE and the user identifier of the UE. The information is generated, and when the UE accesses the service through the EPC again (for example, the EPC receives the service request sent by the eNB), the UE may directly obtain the service identifier from the database according to the user identifier included in the service request of the UE. The maximum number of HARQ processes is sent to the eNB. Therefore, the method further includes: generating a resource scheduling information database based on the correspondence between the resource scheduling information and the user identifier of the target user;

Receiving a third message that is sent by the base station and carrying the user identifier;

According to the user identifier, resource scheduling information corresponding to the user identifier is obtained from the resource scheduling information database.

In the embodiment of the present invention, the third message may be a message including a Service Request, such as an Initial UE message. It is to be understood that the above-listed messages are merely illustrative of the invention, and the invention is not limited thereto.

In the embodiment of the present invention, the maximum number of HARQ processes may be the most supported by the uplink and downlink unified The number of large HARQ processes may also include the maximum number of HARQ processes supported by the uplink (Max HARQ Process Number-Uplink) and the maximum number of HARQ processes supported by the downlink (Max HARQ Process Number-Downlink); more specifically, the maximum supported by the uplink The number of HARQ processes (Max HARQ Process Number-Uplink) can be divided into the maximum number of HARQ processes supported by the FDD system according to the frequency division duplex (FDD) system and the time division duplex (TDD) system (Max HARQ Process Number-Uplink) -FDD), the maximum number of HARQ processes supported by the TDD system (Max HARQ Process Number-Uplink-TDD); The maximum number of HARQ processes supported by the downlink (Max HARQ Process Number-Downlink) can be divided into FDD and TDD, FDD The maximum number of HARQ processes supported by the system downlink (Max HARQ Process Number-Downlink-FDD), and the maximum number of HARQ processes supported by the TDD system (Max HARQ Process Number-Downlink-TDD).

In this way, the flexibility of resource scheduling is further increased.
