Description

Communication method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

With the development of communication technology, long Term Evolution (LTE) technology has been widely applied to various communication scenarios. The frequency band used by LTE is 20MHz in 1785MHz (megahertz) -1805MHz, and the standard cell bandwidth defined by LTE is 6 in 20/15/10/5/3/1.4 MHz.

In the existing LTE network, a large amount of data needs to be interacted between network equipment and user equipment. Generally, in order to increase the uplink rate, the ue transmits uplink data to the network device on the allocated standard cell bandwidth by using a 64-phase Quadrature Amplitude Modulation (QAM) method. In order to increase the downlink rate, the ue may receive downlink data sent by the network device on the allocated standard cell bandwidth in a dual-stream Multiple-Input Multiple-Output (MIMO) manner.

However, because the environment of the LTE network may be complex, it is difficult to always perform communication between the network device and the user equipment in an uplink 64QAM and downlink dual-flow manner, and communication efficiency and quality are difficult to guarantee, which certainly is difficult to meet the communication requirement of the LTE network.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

Before explaining the present invention in detail, an application scenario of the present invention will be explained. Since the bandwidth of the LTE network is only 20MHz at maximum, the bandwidth needs to be allocated to various industries such as oil, electricity and traffic. And each industry obtains the industry authorized bandwidth belonging to the industry through application, selects the standard cell bandwidth which is less than or equal to the industry authorized bandwidth from the industry authorized bandwidths, and establishes the LTE network based on the selected standard cell bandwidth for communication. In addition, even if there is a standard cell bandwidth equal to the applied industry authorized bandwidth, for some industries with high requirements on network reliability, because networking needs to be performed in a dual-network redundant backup manner (i.e., LTE networks are respectively established by two standard cell bandwidths within the industry authorized bandwidth), the sum of the bandwidths of the two selected standard cell bandwidths needs to be less than or equal to the industry authorized bandwidth. For example, in the urban rail transit industry, if an industry authorized bandwidth of 5MHz is applied, networking can be performed only in a mode of 1.4MHz +3MHz, and therefore, the bandwidth actually used for communication in the established LTE network is quite limited.

When networking is completed, the network device in the LTE network may send downlink data to the user equipment, or receive uplink data sent by the user equipment, that is, implement communication with the user equipment. The network device may send network configuration information to the user equipment, where the network configuration information can be used to describe relevant configurations of the current network, including a cell bandwidth of a current cell. When the user equipment receives the network configuration information, the cell bandwidth used for communicating with the network equipment can be determined, and the communication with the network equipment is carried out based on the current cell bandwidth.

The industry authorized bandwidth is the bandwidth that the industry applying the LTE network can apply to. For example, in the urban rail transit industry, the frequency band that can be applied for is 1790MHz-1795MHz, so for this industry, the industry authorized bandwidth is 5MHz.

The standard cell bandwidth is the cell bandwidth defined in the current LTE related protocol. The standard cell bandwidth may comprise 20MHz, 15MHz, 10MHz, 5MHz, 3MHz, or 1.4MHz.

The network device is used for communicating with the user equipment and can be used as a bridge for connecting the user equipment and the core network. The network device may include an evolved Node B (eNB).

A User Equipment (UE) is a User terminal in a network. In different industry domains, user equipment may comprise different forms, such as in urban rail transit, and UEs may comprise autonomous trains and/or non-autonomous trains.

The network configuration information is used to describe the network device and the relevant configuration of the network (or cell) where the user equipment is currently located, such as the cell bandwidth of the currently located cell. Of course, in practical applications, the network configuration information may also be used to illustrate other information related to network configuration.

Fig. 1 is a flowchart illustrating a communication method according to an embodiment of the present invention. The method may be applied to a network device. It should be noted that, the communication method according to the embodiment of the present invention is not limited by the specific sequence shown in fig. 1 and described below, and it should be understood that, in other embodiments, the sequence of some steps in the communication method according to the embodiment of the present invention may be interchanged according to actual needs, or some steps in the communication method may be omitted or deleted. The flow shown in fig. 1 will be explained in detail below.

Step 101, generating network configuration information when a preset condition is met.

Wherein the network configuration information includes: and an extended available resource identifier, which is used for indicating that the cell bandwidth of the cell in which the user equipment is currently located is an extended cell bandwidth, and the extended cell bandwidth is larger than the standard cell bandwidth corresponding to the extended cell bandwidth. In the embodiment of the present invention, the preset condition is a condition indicating that the cell bandwidth of the current cell is switched from the standard cell bandwidth to the corresponding extended cell bandwidth.

For example, the preset condition may be that the occupancy rate of Resource Blocks (RBs) in the current cell bandwidth is greater than the preset Resource Block occupancy rate, or the number of user equipments in the current cell is greater than the preset number of equipment, and the like.

It should be noted that the preset resource block occupancy rate or the preset device number may be determined in advance, for example, by receiving a numerical value submitted by a user, and determining the numerical value as the preset resource block occupancy rate or the preset device number.

The extended available resource identifier may be represented by a number, a letter, a special symbol, or the like. The extended available resource identifier may correspond to an extended cell bandwidth.

The extended cell bandwidth is a cell bandwidth extended for a corresponding standard cell bandwidth. The extended cell bandwidth may be greater than a standard cell bandwidth corresponding to the extended cell. Of course, the expanded cell bandwidth may also be less than or equal to the industry authorized bandwidth, that is, the current cell bandwidth may be maximally expanded to the industry authorized bandwidth.

In addition, in the LTE network, the cell bandwidth is divided into a plurality of RBs, which are the minimum units of the resource allocation frequency domain for data transmission of the physical layer, and each RB occupies 0.18MHz. Therefore, based on the bandwidth of the existing standard cell, the bandwidth of the standard cell is expanded by increasing the number of RBs. That is, N additional RBs are added based on the number of RBs already included in the standard cell bandwidth.

N is an integer greater than 0. For example, N may be 1 or 2.

The network device may generate a corresponding extended available resource identifier based on the extended cell bandwidth, and further generate and obtain the network configuration information.

For example, the extension is made for a standard cell bandwidth of 1.4MHz, and the existing standard cell bandwidth of 1.4MHz includes 6 RBs. In the embodiment of the present invention, an RB is added on each of two sides of the standard cell bandwidth, and then the extended cell bandwidth may be 1.76MHz, so that the network device generates network configuration information, where the network configuration information carries an extended available resource identifier n8. Alternatively, the extension is made for a standard cell bandwidth of 3MHz, which includes 15 RBs in the existing 3MHz standard cell bandwidth. In the embodiment of the present invention, an RB is added to each of two sides of the standard cell bandwidth, and then the extended cell bandwidth may be 3.36MHz, so that network configuration information may be generated, where the network configuration information carries an extended available resource identifier n17.

Step 102, sending network configuration information to the user equipment to instruct the user equipment to communicate with the network equipment based on the extended cell bandwidth.

In order to enable the user equipment to determine the cell bandwidth used for current communication, so as to perform communication with the network equipment based on the expanded cell bandwidth, and improve communication efficiency and quality, the network configuration information may be sent to the user equipment.

The network device may send a Master Information Block (MIB) to the user equipment through a Physical Broadcast Channel (PBCH), where the MIB may carry network configuration Information.

The PBCH is a control channel for carrying the MIB.

For example, one MIB information may include:

and the dl-Bandwidth is a downlink Bandwidth parameter and is used for indicating the Bandwidth size of the downlink. The dl-Bandwidth may include the aforementioned extended available resource identifier, for example, when the extended available resource identifier included in the dl-Bandwidth is n8, the Bandwidth of the downlink can be indicated as the Bandwidth extended for 1.4MHz, that is, 1.76MHz.

It should be noted that, in practical applications, the network device may also send control information related to communication to the user equipment through other control channels.

In the embodiment of the present invention, a network device generates network configuration information, where the network configuration information includes an extended available resource identifier, and the extended available resource identifier is used to indicate that a current cell bandwidth is an extended cell bandwidth, and the extended cell bandwidth is extended on the basis of a standard cell bandwidth. Therefore, the network configuration information is sent to the user equipment, the network equipment can be ensured to communicate with the user equipment by expanding the cell bandwidth, the communication efficiency and quality are improved, and the utilization rate of the cell bandwidth is also improved.

Fig. 2 is a flowchart illustrating a communication method according to an embodiment of the present invention. The method may be applied to a user equipment. It should be noted that, the communication method according to the embodiment of the present invention is not limited by the specific sequence shown in fig. 2 and described below, and it should be understood that, in other embodiments, the sequence of some steps in the communication method according to the embodiment of the present invention may be interchanged according to actual needs, or some steps in the communication method may be omitted or deleted. The flow shown in fig. 2 will be explained in detail below.

Step 201, receiving network configuration information sent by a network device.

The network configuration information is generated by the network device when meeting a preset condition, and the network configuration information comprises: and the extended available resource identifier is used for indicating the cell bandwidth of the cell where the user equipment is currently located to be an extended cell bandwidth, and the extended cell bandwidth is greater than the standard cell bandwidth corresponding to the extended cell bandwidth.

In the foregoing embodiments, the specific process of generating and sending the network configuration information by the network device has been described in detail, and will not be repeated here.

The user equipment may receive the network configuration information through a control channel with the network device.

Step 202, according to the network configuration information, performing communication with the network device based on the extended cell bandwidth.

In order to communicate with the network device based on the extended cell bandwidth and improve the communication efficiency and quality, the network device may communicate with the network device based on the extended cell bandwidth according to the received network configuration information.

The user equipment can obtain the extended available resource identifier from the network configuration information, so as to determine the current cell bandwidth as the corresponding extended cell bandwidth, and thus, the user equipment can send uplink data to the network equipment or receive downlink data from the network equipment based on the extended cell bandwidth.

The current cell bandwidth may be determined from the available resource identifier based on the extended available resource identifier, and the number of resource blocks corresponding to the cell bandwidth may be obtained based on the correspondence between the cell bandwidth and the number of resource blocks.

For example, the extended available resource identifier received by the ue includes n8, and it is determined that the current cell bandwidth is a bandwidth extended to 1.4MHz (for example, 1.76 MHz) based on n8, then the corresponding number of resource blocks may be obtained as 8 from the correspondence between the cell bandwidth and the number of resource blocks shown in table 1 below.

TABLE 1

Cell bandwidth/(MHz)	Number of resource blocks
		1.4	6
1.76	8
		3	15
5	25
		10	50
15	75
		20	100

It should be noted that, in the embodiment of the present invention, only the correspondence between the cell bandwidth and the number of resource blocks is described in table 1, and the correspondence between the cell bandwidth and the number of resource blocks is not limited.

It should be further noted that the ue may obtain and store the corresponding relationship between the cell bandwidth and the number of resource blocks in advance.

In the embodiment of the present invention, the ue may receive network configuration information, where the network configuration information includes an extended available resource identifier, and the extended available resource identifier is used to indicate that a current cell bandwidth is an extended cell bandwidth, and the extended cell bandwidth is extended based on a standard cell bandwidth. Therefore, the network equipment can communicate with the user equipment by expanding the cell bandwidth, so that the communication efficiency and quality are improved, and the utilization rate of the cell bandwidth is also improved.

Fig. 3 is a flowchart illustrating a communication method according to an embodiment of the present invention. The method may be applied in an interaction between a network device and a user equipment. It should be noted that, the communication method according to the embodiment of the present invention is not limited by the specific sequence shown in fig. 3 and described below, and it should be understood that, in other embodiments, the sequence of some steps in the communication method according to the embodiment of the present invention may be interchanged according to actual needs, or some steps in the communication method may be omitted or deleted. The flow shown in fig. 3 will be explained in detail below.

Step 301, when a preset condition is met, the network device generates network configuration information.

Wherein the network configuration information includes: and the extended available resource identifier is used for indicating the cell bandwidth of the cell in which the user equipment is currently located as an extended cell bandwidth, and the extended cell bandwidth is greater than the standard cell bandwidth corresponding to the extended cell bandwidth.

Optionally, in order to avoid the problem that the expanded cell bandwidth exceeds the industry authorized bandwidth, the normal communication between the network device and the user equipment is ensured, the reliability and accuracy of expanding the cell bandwidth are improved, and the spare bandwidth except the standard cell bandwidth can be obtained within the industry authorized bandwidth range; determining an expanded RB and an available bandwidth of the expanded RB in the spare bandwidth; determining the sum of the occupiable bandwidth and the standard cell bandwidth as the extended cell bandwidth; and generating the extended available resource identifier, and carrying the extended available resource identifier in the network configuration information.

The industry licensed bandwidth may be obtained by a predetermined determination, such as by receiving a user submitted value. Of course, in practical applications, the determination may be made in other ways.

The spare bandwidth is the bandwidth which is not covered by any standard cell bandwidth or extended cell bandwidth in the industry authorized bandwidth, and can be used as a protection bandwidth.

It should be noted that the manner of determining the spare bandwidth may be the same as the manner of determining the industry authorized bandwidth. Alternatively, the spare bandwidth may be determined based on the industry licensed bandwidth and the standard cell bandwidth.

For example, in the urban rail transit industry, an industry authorized bandwidth of 5MHz is applied, networking is performed in a mode of 1.4MHz +3MHz, wherein the remaining 0.6MHz is a spare bandwidth.

The occupiable bandwidths of the extended RB and the extended RB may be determined based on the size of the spare bandwidth, and of course, in practical applications, the occupiable bandwidths of the extended RB and the extended RB may also be obtained by presetting, for example, the number of the extended RB is 2, and correspondingly, the occupied bandwidth of the extended RB is 0.36MHz.

When the number of the extended RBs includes more than one, the more than one extended RBs may be distributed on the same side of the standard cell bandwidth, and may be distributed on both sides of the standard cell bandwidth in any ratio. In addition, the extended RBs on the same side are adjacent two by two and are adjacent to the RB on the side edge of the standard cell bandwidth.

Optionally, since the standard cell bandwidth includes a protection bandwidth, and when the standard cell bandwidth is expanded, the protection bandwidth may also be utilized, so as to improve the accuracy of determining the number of RBs and the occupied bandwidth of the expanded RBs as much as possible, and fully utilize the industry authorized bandwidth, the number N of the expanded RBs and the occupied bandwidth of the expanded RB may be determined according to the lowest protection bandwidth, the bandwidth occupied by each expanded RB and the protection bandwidth included in the standard cell bandwidth, where N is an integer greater than 0, in the spare bandwidth.

The minimum protection bandwidth is the lowest bandwidth of the cell bandwidths as the protection bandwidth, and the minimum protection bandwidth can be obtained by setting in advance.

The spare bandwidth and the protection bandwidth included in the standard cell bandwidth can be accumulated, the lowest protection bandwidth is subtracted from the accumulated bandwidth, the obtained difference is divided by the bandwidth occupied by each extension RB, the integer of the obtained quotient is the maximum value of the number N of the extension RBs, and the sum of the bandwidths occupied by the N extension RBs is the occupied bandwidth of the extension RB.

Optionally, taking an example that a standard cell bandwidth is 1.4MHz, the standard cell bandwidth is small and often difficult to meet communication requirements, for example, in urban rail transit, a bandwidth of 1.4MHz is difficult to meet communication requirements of 4 trains in a single cell, therefore, in order to improve communication efficiency and quality in the standard cell bandwidth of 1.4MHz, the standard cell bandwidth is 1.4MHz and includes 6 RBs, and the extended cell bandwidth includes 6+N resource blocks; when N is 2, the occupied bandwidth of the extended resource block is 0.36MHz; or, when N is 4, the occupied bandwidth of the extended resource block is 0.72MHz.

The standard cell bandwidth comprises a guard bandwidth which can be 0.32MHz, the bandwidth occupied by each extended RB is 0.18MHz, the lowest guard bandwidth is 0.2MHz, and the spare bandwidth is not less than 0.6MHz; then (0.6 + 0.32) is divided by 0.18, the quotient is 4, and the remainder is 0.2, so the maximum value of N is 4.

It should be noted that, when N is 2, the extended cell bandwidth is (1.4 + 0.36-0.32) =1.44MHz; when N is 4, the bandwidth of the extended cell is (1.4 + 0.72-0.32) =1.8MHz;

the number of RBs included in the cell bandwidth is increased from 6 to 8, resources are increased by more than 30%, the uplink and downlink throughput of the cell is remarkably improved, and the communication requirement of a scene with small industry authorized bandwidth is met, for example, the throughput requirement of 1Mbps of uplink and downlink of a single-cell 4 train in urban rail transit can be met. In addition, when the authorized bandwidth of the industry is 5MHz, the dual-network redundancy backup can be carried out by adopting 3MHz additionally.

Optionally, since the standard bandwidth already includes the guard bandwidth, in order to ensure that the spare bandwidth is fully utilized, in the spare bandwidth, the number N of the extension RBs and the available bandwidth of the extension RB may be determined according to the bandwidth occupied by each extension RB, where N is an integer greater than 0.

The spare bandwidth may be divided by each extension RB, an integer of the obtained quotient is a maximum value of the number N of extension RBs, and a sum of bandwidths occupied by the N extension RBs is an occupiable bandwidth of the extension RB. In addition, the sum of the occupiable bandwidth of the extended RB and the standard cell bandwidth is the extended cell bandwidth.

For example, if the standard cell bandwidth is 1.4MHz and includes 6 RBs, the standard cell bandwidth includes a guard bandwidth of 0.32MHz, each extended RB occupies 0.18MHz, and the spare bandwidth is not less than 0.6MHz, 0.6 is divided by 0.18, the quotient is 3, and the remainder is 0.06, so the maximum value of N may be 3. When N is 2, the occupied bandwidth of the extended RB is 0.36MHz, and correspondingly, the extended cell bandwidth is 1.4+0.36=1.76mhz.

Optionally, since the cell may include a plurality of user equipments, and the plurality of user equipments may all communicate with the network equipment through the RBs included in the current cell bandwidth, in order to indicate, to the user equipment, the RBs available to the user equipment, and ensure that each user equipment can communicate with the network equipment safely and reliably, the network configuration information further includes uplink available resource indication information or downlink available resource indication information; the uplink available resource indication information is used for indicating the allocated RBs available for the user equipment in the extended cell bandwidth; the downlink available resource indication information is used for indicating the allocated RBs available for the user equipment in the extended cell bandwidth.

The network device may determine an RB available for downlink to the user equipment, and then generate the downlink available resource indication information, or determine an RB available for uplink to the user equipment, and then generate the uplink available resource indication information.

Optionally, as can be seen from the foregoing, the available resource indication information includes downlink available resource indication information or uplink available resource indication information, and different resource allocation manners may also be provided for uplink/downlink, so to ensure that an RB available for uplink/downlink can be accurately described to the user equipment, and further improve communication efficiency and quality, the downlink available resource indication information is determined according to a downlink resource allocation type; or, determining the uplink available resource indication information according to the uplink resource allocation type.

The downlink resource allocation type may include a resource allocation manner 0, a resource allocation manner 1, and a resource allocation manner 2, and the uplink resource allocation type may include a resource allocation manner 0 and a resource allocation manner 1.

The Downlink resource allocation type may be determined by Downlink Control Information (DCI) Information acquired from a Physical Downlink Shared Channel (PDSCH); the Uplink resource allocation type may be determined by DCI information acquired from a Physical Uplink Control Channel (PUSCH).

When the DCI information includes DCI1, DCI2A, DCI B or DCI2C, and the "Resource allocation header" field in the DCI information does not exist or is 0, the downlink Resource allocation type is Resource allocation mode 0; when the DCI information includes DCI1, DCI2, or DCI2B, and a "Resource allocation header" field in the DCI information is 1, the downlink Resource allocation type is a Resource allocation mode 1; when the DCI information includes DCI1A, DCI1B, DCI1C, DCI D, the downlink resource allocation type is resource allocation scheme 2. When the DCI information comprises DCI0 or DCI4, and the field of the Resource allocation header does not exist in the DCI information or the field of the Resource allocation header is 0, the uplink Resource allocation type is a Resource allocation mode 0; when the DCI information includes DCI0 or DCI4 and the "Resource allocation header" field in the DCI information is 1, the uplink Resource allocation type is Resource allocation mode 1.

The PDSCH may be used for transmitting downlink data, and the PUSCH may be used for transmitting uplink data.

Optionally, the downlink available resource indication information may be determined according to the downlink resource allocation type by any one of the following three ways:

in a first mode, if the downlink resource allocation type is the resource allocation type 0, the allocated RB available for the downlink of the user equipment is indicated by using the first bit information based on the number of resource blocks included in the bandwidth of the extended cell.

Each bit of the first bit information is used to indicate whether a corresponding resource block Group is available for downlink of the user equipment, where the Resource Block Group (RBG) includes at least one RB.

It should be noted that the resource block group may include a plurality of consecutive RBs, and the size of the RBG is related to the number of resource blocks that the current cell bandwidth can include.

For example, a correspondence relationship between the number of resource blocks that a current cell bandwidth may include and the RBG size (i.e., the number of RBs included) may be as shown in table 2 below.

TABLE 2

Number of resource blocks	RBG size
		Less than or equal to 10	1
11 or more and 26 or less	2
		27 or more and 63 or less	3
Greater than or equal to 64 and less than or equal to 110	4

It should be noted that, in the embodiment of the present invention, only the table 2 is used to describe the correspondence between the number of resource blocks that can be included in the current cell bandwidth and the RBG size, and the correspondence between the number of resource blocks that can be included in the current cell bandwidth and the RBG size is not limited.

In the second mode, if the downlink resource allocation type is the resource allocation type 1, the allocated RB available for the downlink of the user equipment is indicated by using the second bit information based on the number of resource blocks included in the bandwidth of the extended cell.

The second bit information includes first bit sub information, second bit sub information, and third bit sub information, where the first bit sub information is used to indicate an allocated resource block group available for downlink of the user equipment, the second bit sub information is used to indicate whether an RB indicated by the third bit sub information is offset, and each bit of the third bit sub information is used to indicate whether each RB included in the resource block group is available for downlink of the user equipment.

The first bit of sub-information has a length of [ log ] ₂ (P)]Wherein P is RBG size; the second bit sub information is 1 bit, wherein 0 represents no offset, and 1 represents offset; the third bit sub information has a length of

Wherein the content of the first and second substances,

is the number of resource blocks available for downlink.

For example, for an extended cell bandwidth of 1.76MHz and 8 RBs, if the downlink resource allocation type is resource allocation type 1, the first bit sub information in the downlink available resource indication information is 0, the second bit sub information is 1, and the third bit sub information occupies 7 bits, that is, 8 bits indicate whether each RB is available to the user equipment.

And thirdly, if the downlink resource allocation type is the resource allocation type 2, indicating the allocated downlink available RB for the user equipment by adopting third bit information based on the number of resource blocks included by the bandwidth of the extended cell.

Wherein the third bit information includes first bit sub information and second bit sub information, the first bit sub information indicating whether the RBs indicated by the second bit sub information are concentrated or scattered; the second bit sub information is used to indicate RBs available for downlink for the user equipment.

Optionally, the uplink available resource indication information may be determined according to the uplink resource allocation type in any one of the following two manners:

in a first manner, if the uplink resource allocation type is resource allocation type 0, the allocated RB available for the user equipment uplink is indicated by using the fourth bit information based on the number of resource blocks included in the extended cell bandwidth.

Wherein the fourth bit information includes first bit sub information and second bit sub information, the first bit sub information being for whether the RBs indicated by the second bit sub information are concentrated or scattered; the second bit sub information is used to indicate RBs available for uplink for the user equipment.

In the second mode, if the uplink resource allocation type is resource allocation type 1, the allocated at least one continuous resource block group available for the uplink of the user equipment is indicated by using the fifth bit information based on the number of resource blocks included in the extended cell bandwidth, and the RB included in each resource block group is available for the uplink of the user equipment.

Step 302, the network device sends network configuration information to the user equipment.

For the manner in which the network device sends the network configuration information to the user equipment, reference may be made to the foregoing related description, which is not described in detail herein.

Step 303, the user equipment receives the network configuration information sent by the network equipment.

Optionally, the user equipment may receive and receive the downlink available resource indication information sent by the network device through any one of the following three manners:

in a first mode, first bit information sent by a network device is received.

Each bit of the first bit information is used to indicate whether the corresponding resource block group is available for downlink of the user equipment, and the resource block group includes at least one RB.

For example, the ue receives that the downlink available resource indication information is "10010010," and determines that the extended cell bandwidth is 1.76MHz, and determines from table 1 that the number of resource blocks that can be included in the extended cell bandwidth is 8, and further determines from table 2 that the RBGs have a size of 1, that is, each RBG includes one RB, so that the ue may determine that current RBs 0, RB3, and RB7 are available for the ue in downlink.

And receiving second bit information sent by the network equipment.

And a third mode is to receive third bit information sent by the network equipment.

When the user equipment determines an RB available for downlink for the user equipment in the extended cell bandwidth, downlink data from the network equipment may be received based on the determined RB.

Optionally, the ue may receive the uplink available resource indication information sent by the network device in any one of the following two manners:

in the first mode, fourth bit information sent by the network device is received.

And receiving fifth bit information sent by the network equipment in the second mode.

Wherein, the fifth bit information is used to indicate at least one allocated continuous resource block group available for the uplink of the user equipment, and RBs included in each resource block group are available for the uplink of the user equipment.

When the user equipment determines the RBs available upstream for the user equipment in the extended cell bandwidth, the data may be upstream to the self network device based on the determined RBs.
