Step 101, when meeting preset condition, network configuration information is generated.
Wherein, network configuration information includes: extension available resources mark, and extension available resources mark is used to indicate user The bandwidth of cell that equipment is presently in cell is Extended Cell bandwidth, which is wider than corresponding with Extended Cell bandwidth Normal cell bandwidth.In embodiments of the present invention, preset condition is the bandwidth of cell that instruction will be presently in cell, from standard Bandwidth of cell switches to the condition of corresponding Extended Cell bandwidth.
For example, preset condition can be the occupancy of resource block (Resource Block, RB) in current bandwidth of cell Greater than default resource block occupancy, alternatively, the number of user equipment for being presently in cell is greater than default number of devices etc., certainly, In practical applications, preset condition can also include other conditions.
It should be noted that default resource block occupancy or default number of devices can be by being determined in advance, for example, connecing The numerical value that user submits is received, and the numerical value is determined as default resource block occupancy or default number of devices.
Extension available resources mark can be indicated by the characters such as number, letter, additional character.The extension available resources Mark can correspond to a kind of Extended Cell bandwidth.
Extended Cell bandwidth is for the bandwidth of cell after corresponding normal cell bandwidth expansion.The Extended Cell bandwidth can To be greater than normal cell corresponding with Extended Cell bandwidth.Certainly, which is also less than or is equal to industry Authorized bandwidth that is to say that maximum can be by current area bandwidth expansion to industry authorized bandwidth.
In addition, bandwidth of cell is divided into the resource allocation that multiple RB are transmitting data in physical layer due in the lte networks Frequency domain minimum unit, each RB occupy 0.18MHz.Therefore, on the basis of existing normal cell bandwidth, by increasing RB Number realizes the extension to normal cell bandwidth.It that is to say, on the basis of bandwidth has included in normal cell RB is several, additionally Increase N number of RB.
It should be noted that N is the integer greater than 0.For example, N can be 1 or 2.
The network equipment can be based on Extended Cell bandwidth, generate corresponding extension available resources mark, and then generate and obtain Network configuration information.
For example, the normal cell bandwidth for 1.4MHz is extended, the normal cell bandwidth of existing 1.4MHz includes 6 RB.In embodiments of the present invention, respectively increase a RB in the two sides of the normal cell bandwidth, then the Extended Cell bandwidth after extending It can be 1.76MHz, therefore, the network equipment generates network configuration information, and extension available resources are carried in the network configuration information It is identified as n8.Alternatively, the normal cell bandwidth for 3MHz is extended, the normal cell bandwidth of existing 3MHz includes 15 RB.In embodiments of the present invention, respectively increase a RB in the two sides of the normal cell bandwidth, then the Extended Cell bandwidth after extending It can be 3.36MHz, therefore network configuration information can be generated, extension available resources are carried in the network configuration information and are identified as n17。
Step 102, network configuration information is sent to user equipment, to indicate that the user equipment is based on the Extended Cell bandwidth It is communicated with the network equipment.
In order to make user equipment determine bandwidth of cell used by present communications, to be based on Extended Cell bandwidth and network Equipment is communicated, and is improved communication efficiency and quality, which can be sent to user equipment.
The network equipment can be set by Physical Broadcast Channel (Physical Broadcast Channel, PBCH) to user Preparation is sent Master Information Block (Master Information Block, MIB), can carry network configuration information in the MIB.
Wherein, PBCH is a kind of control channel, for carrying MIB.
For example, a kind of mib information may include:
Wherein, dl-Bandwidth is downlink bandwidth parameter, is used to indicate the amount of bandwidth of downlink.The dl- Bandwidth may include extension available resources mark above-mentioned, for example, working as the extension available resources that dl-Bandwidth includes It is identified as n8, then the bandwidth for capableing of indicating downlink link is for the bandwidth after 1.4MHz extension, as 1.76MHz.
It should be noted that in practical applications, the network equipment can also be sent out by other control channels to user equipment Send control information relevant to communication.
In embodiments of the present invention, the network equipment generates network configuration information, which includes that extension is available Resource identification, and it is Extended Cell bandwidth, the Extended Cell band that extension available resources mark, which is used to indicate current area bandwidth, Width is to extend to obtain on the basis of the bandwidth of normal cell.Therefore, which is sent to user equipment, it is ensured that net Network equipment can be communicated by Extended Cell bandwidth with user equipment, improved communication efficiency and quality, also improved bandwidth of cell Utilization rate.
It referring to figure 2., is a kind of flow diagram of communication means provided by the embodiment of the present invention.This method can answer For user equipment.It should be noted that communication means described in the embodiment of the present invention is not with Fig. 2 and tool as described below Body sequence is limitation, it should be understood that in other embodiments, communication means part step described in the embodiment of the present invention Sequence can be exchanged with each other according to actual needs or part steps therein also can be omitted or delete.It below will be to Fig. 2 institute The process shown is described in detail.
Step 201, the network configuration information that the network equipment is sent is received.
Wherein, network configuration information generation when meeting preset condition by the network equipment, the network configuration information include: to expand Exhibition available resources mark, it is that extension is small that extension available resources mark, which is used to indicate user equipment and is presently in the bandwidth of cell of cell, Zone is wide, which is wider than normal cell bandwidth corresponding with the Extended Cell bandwidth.
In the aforementioned embodiment, it has been detailed that network equipment generation, the detailed process for sending network configuration information, This is no longer repeated.
User equipment can be by the control channel between the network equipment, to receive network configuration information.
Step 202, it according to network configuration information, is communicated based on Extended Cell bandwidth with the network equipment.
In order to be communicated based on Extended Cell bandwidth with the network equipment, raising communication efficiency and quality can be according to institutes The network configuration information received is communicated based on Extended Cell bandwidth with the network equipment.
User equipment can acquire extension available resources mark from the network configuration information, so that it is determined that current Bandwidth of cell is corresponding Extended Cell bandwidth, so as to be based on the Extended Cell bandwidth, sends upper line number to the network equipment According to or receive the downlink data from the network equipment.
Wherein it is possible to current bandwidth of cell be determined from available resources mark, based on small based on extension available resources mark In the wide corresponding relationship between number of resource blocks of zone, number of resource blocks corresponding with the bandwidth of cell is obtained.
For example, the extension available resources mark that user equipment receives includes n8, determine that current area bandwidth is based on n8 It, then can be between bandwidth of cell and number of resource blocks as shown in table 1 below to the bandwidth (such as 1.76MHz) after 1.4MHz extension Corresponding relationship in, obtain corresponding number of resource blocks be 8.
Table 1
Bandwidth of cell/(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 the embodiment of the present invention only the above table 1 to the corresponding relationship between bandwidth of cell and number of resource blocks into Row explanation, does not constitute the corresponding relationship between bandwidth of cell and number of resource blocks and limits.
It should also be noted that, user equipment can obtain the corresponding relationship between bandwidth of cell and number of resource blocks in advance, And it is stored.
In embodiments of the present invention, user equipment can receive network configuration information, which includes extension Available resources mark, and it is Extended Cell bandwidth that extension available resources mark, which is used to indicate current area bandwidth, the extension is small Zone width is to extend to obtain on the basis of the bandwidth of normal cell.Therefore, the network equipment can pass through Extended Cell bandwidth and use The communication of family equipment, improves communication efficiency and quality, also improves the utilization rate of bandwidth of cell.
It referring to figure 3., is a kind of flow diagram of communication means provided by the embodiment of the present invention.This method can answer For in the interaction between the network equipment and user equipment.It should be noted that communication means described in the embodiment of the present invention is simultaneously It is not limitation with Fig. 3 and specific order as described below, it should be understood that in other embodiments, described in the embodiment of the present invention The sequence of communication means part step can be exchanged with each other according to actual needs or part steps therein can also be with It omits or deletes.Process shown in Fig. 3 will be described in detail below.
Step 301, when meeting preset condition, the network equipment generates network configuration information.
Wherein, network configuration information includes: extension available resources mark, and extension available resources mark is used to indicate user The bandwidth of cell that equipment is presently in cell is Extended Cell bandwidth, which is wider than and the Extended Cell bandwidth pair The normal cell bandwidth answered.
Optionally, in order to avoid extension after bandwidth of cell exceed industry authorized bandwidth the problem of, it is ensured that the network equipment with The normal communication of user equipment improves the reliability and accuracy being extended to bandwidth of cell, can be in industry authorized bandwidth In range, the idle bandwidth in addition to the bandwidth of normal cell is obtained；In the idle bandwidth, determines extension RB and extend RB's It can occupied bandwidth；By this can occupied bandwidth and the normal cell bandwidth sum, be determined as the Extended Cell bandwidth；Generate the expansion Available resources mark is opened up, and extension available resources mark is carried in the network configuration information.
Industry authorized bandwidth can be obtained by being determined in advance to obtain, such as by receiving the numerical value that user submits.Certainly, In practical applications, it can also determine otherwise.
Idle bandwidth is the bandwidth not covered by any standard bandwidth of cell or Extended Cell bandwidth in industry authorized bandwidth, The idle bandwidth can be used as protection bandwidth.
It should be noted that determine the mode of idle bandwidth, it can be identical as the mode of industry authorized bandwidth is determined.Or Person can be based on industry authorized bandwidth and normal cell bandwidth, determine idle bandwidth.
For example, the industry authorized bandwidth of 5MHz is arrived in application in urban track traffic industry, pass through 1.4MHz+3MHz's Mode networking, wherein remaining 0.6MHz is idle bandwidth.
Extend RB and extend RB can occupied bandwidth can based on the size of idle bandwidth determine, certainly, actually answer In, extend RB and extend RB can occupied bandwidth can also by presetting to obtain, for example, extension RB number be 2 It is a, correspondingly, the bandwidth that extension RB is occupied is 0.36MHz.
It should be noted that the more than one extension RB can be distributed when the number for extending RB includes more than one The same side of bandwidth in normal cell, it is of course also possible to be distributed in the two sides of normal cell bandwidth with arbitrary ratio.In addition, Extension RB in the same side is adjacent two-by-two, and adjacent with the RB of the normal cell bandwidth side edge.
Optionally, due to will include protection bandwidth in the bandwidth of normal cell, when being extended to the normal cell bandwidth, This part protection bandwidth can also be utilized, and therefore, occupy band to improve determining RB number and extension RB as far as possible Wide accuracy makes full use of industry authorized bandwidth, can be in idle bandwidth, according to minimal protection bandwidth, each extension RB The protection bandwidth that the bandwidth and normal cell bandwidth of occupancy include determines occupying for the number N and extension RB of extension RB Bandwidth, N are the integer greater than 0.
