Network in the embodiment of the present application can refer to public land mobile network (Public Land Mobile Network, PLMN) or equipment is to equipment (Device to Device, D2D) network or Machine To Machine/people (Machine to Machine/Man, M2M) network or other networks, Fig. 1 is the rough schematic view illustrated, it can also include other terminal devices in network, not drawn in Fig. 1.

Antenna is a kind of energy conversion device, is the device realizing space radio wave energy and high-frequency current energy and mutually converting.Due to the limitation of antenna size, identical size can be used in high band and place more antennas, thus multi-antenna technology on high band using it is upper advantageously.But the propagation loss of progress signal transmission, penetration loss are significantly larger than the transmission of the signal in low-frequency range on high band.And existing net is all low frequency networking, website is built according to the covering power of low-frequency range, and the multiaerial system of high band also requires emphasis using low frequency website from networking cost.Therefore the multiaerial system of high band needs to make up the difference between low-and high-frequency on signal propagation losses using beam gain.In this way, the covering of common signal channel in the cell is faced with bigger test in high frequency multiaerial system.

In long term evolution (Long Term Evolution, LTE) common signal channel such as CRS, CSI-RS, PCFICH, PHICH, P-SCH, S-SCH, PBCH, PDCCH etc. in the downlink radio frame of system, their occupied running time-frequency resources when carrying out signal transmitting are distributed in different running time-frequency resource positions, such as PDCCH, PCFICH, PHICH occupy preceding 1 to 3 symbol in each subframe, occupy continuous all subcarriers in frequency domain.Other common signal channels such as PBCH, SSCH, PSCH occupy multiple symbols in time domain, occupy multiple continuous subcarriers in frequency domain.The network equipment generally requires the range for covering entire cell when sending these common signal channels, can normally receive these common signal channels with all user equipmenies guaranteed in all cells, therefore the network equipment needs to emit these common signal channels using broad beam.And for the dedicated channel of user equipment, the network equipment then needs to be emitted using narrow beam as much as possible, covers single user's equipment to be supplied to the maximum gain of the user equipment.When the network equipment sends these common signal channels using broad beam, its transmission power is generally significantly less than power when narrow beam being used to send signal, therefore for covering weaker region such as cell edge in cell there are when user equipment, these user equipmenies may not receive the common signal channel of network equipment transmission.And in the larger system of aerial array, existing gain inequality will become more apparent between narrow beam and broad beam.

In existing multiaerial system, it is all by the way of increasing equipment or network cost, to solve the problems, such as that the covering of common signal channel in the cell is restricted, such as by increasing transmission power, reducing the modes such as radius of society, increase new site, it is all forced by the way of no matter for equipment vendor or operator.

In order to improve the coverage condition of common signal channel in the cell, the embodiment of the present application proposes a kind of method for transmitting signal, by to secondary carrier (Slave Component Carrier, SCC the different types of common signal channel on) is sent using the wave beam of different in width, so that every kind of common signal channel can realize more effective covering, so that more user equipmenies in cell be enable to receive required common signal channel.

Fig. 2 is the process interaction figure of the method for the transmission signal of the embodiment of the present application.The network equipment shown in Figure 2 can be for example the network equipment 10 shown in Fig. 1, terminal device shown in Figure 2 can be for example terminal device 20 shown in Fig. 1, but the network equipment 10 can be between the multiple terminal devices through antenna and including terminal device 20, signal transmission is carried out using the method for the embodiment of the present application, method performed by other terminal devices can be in method performed by reference terminal equipment 20, for sake of simplicity, which is not described herein again.As shown in Fig. 2, this method comprises:

In 210, the network equipment determines the beam information for sending the common signal channel according to the type of common signal channel to be sent on secondary carrier SCC.

Wherein, which includes the beam angle for sending the common signal.

In 220, for the network equipment according to the beam information, it is public on SCC to the terminal device of first community to send this Channel.

Optionally, as one embodiment, before 220, i.e., before the network equipment sends the common signal channel to the terminal device of first community on SCC, this method further include: the network equipment carries out slicing processing to the common signal channel.Further, the network equipment can send the slicing treated the common signal channel to the terminal device of first community on SCC, and on the region without common signal channel covering in first community, send the clipped noise that slicing processing generates.

Specifically, the transmitting of common signal channel is all not have freedom degree to carry out shot noise on airspace using identical broad beam on existing SCC.And in the embodiment of the present application, main carrier (Primary Component Carrier, PCC transmission is carried out using broad beam on), and different narrow beams can be generated on SCC for sending common signal channel, freedom degree is thus produced on airspace to be used to send clipped noise (clipped noise can be sent on the region that narrow beam is not covered with), thus the network equipment can carry out the slicing processing in frequency domain and airspace, and the clipped noise that slicing generates is launched.The clipped noise can be launched on the airspace direction that no common signal channel covers, so as to reduce the total peak-to-average ratio of signal.

In 230, the terminal device of first community receives the common signal channel that the network equipment is sent according to the beam information of common signal channel on SCC.

Wherein, which is that the network equipment is determining according to the type of the common signal channel, which includes the beam angle for sending the common signal.

In 240, terminal device accesses first community according to the common signal channel.

Optionally, the type of the common signal channel includes any one in following: for sending common signal channel, downlink physical control channel PDCCH, Physical Control Format Indicator Channel PCFICH, physical mixing retransmission indicating chanel PHICH, common signal channel, primary synchronization channel P-SCH, auxiliary synchronization channel S-SCH and the broadcast channel BCH for sending channel status instruction reference signal CSI-RS of cell reference signals CRS.

Specifically, the network equipment is when sending common signal channel to terminal device, it can determine the type of the common signal channel to be sent, and according to the type of the common signal channel, determine that the beam information such as beam angle for sending the common signal channel, the beam angle determine the angular range that the wave beam can cover.Since different common signal channels can be sent using different beam angles, and not all common signal channel requires to be sent using broad beam to cover entire cell, the thus terminal device of overlay area for example weak for specific regions some in cell, the common signal channel of network equipment transmission can be received preferably to obtain cell information and access cell, realize the communication with the network equipment.

Here, the terminal device of same coverage area is located in cell, the transmission conditions of channel are similar.For example, the terminal device in the closer region in base station is " center covering "；Terminal device apart from the farther away region in base station is " medium covering "；Terminal device in the regions such as cell edge or basement is " edges cover ".

In addition, comparatively narrow beam (wide beam) and broad beam (narrow beam) are, such as the common signal channel sent using broad beam can whole terminal devices in coverage cell, i.e. the broad beam can be used in whole terminal devices into cell and sends common signal channel；And only the wave beam in a part of region in coverage cell is properly termed as narrow beam, which can be used in the section terminating equipment into cell and sends common signal channel.For example, a usual cell is located at the region of the 120 degree of angles in base station covering or the region of 60 degree angles covering, and whens 3 sector networkings, corresponding angle of coverage was 120 degree, and whens 6 sector networkings, corresponding angle of coverage was 60 degree.By taking 3 sector networkings as an example, cell is located at the region of the 120 degree of angles in base station covering, at this moment, the wave beam that the beam angle (referring to beam gain from the beam angle after peak-fall 3dB) of antenna transmitting is 65 degree can cover the cell within the scope of 120 degree, which can be known as broad beam.

In multi-antenna systems, multiplexer channel respectively drives different antenna oscillators, and in space formation different directions and the channel to every paths carries out weighed value adjusting (being adjusted to the amplitude and phase of the wave beam for transmitting the channel) Wave beam.Different wave beams is needed to form on different channels to send common signal channel, in beam forming process, narrow beam when being weighted processing, when be weighted on all channels, the weight amplitude maximum on each channel can expire width, and only phase is variant；And broad beam is that the weighting of full width is carried out on a few channel, the weight on other channels is smaller, or even can be zero, because the effect that width weighting is expired in each channel can make wave beam narrow, broad beam can only sacrifice part weight.

Different types of common signal channel is sent using narrow beam or broad beam, needs to consider various constraints.Such as, different types of common signal channel has the function of different, the access that narrow beam is sent the terminal device without influencing entire cell can be used in some common signal channels, and some common signal channels must use broad beam be transmitted such that all terminal devices in cell can access cell.

Optionally, as one embodiment, if the type of the common signal channel is any one in following, which makes the terminal device for only covering specific region in first community on SCC for sending the wave beam of the common signal channel: for sending common signal channel, PDCCH, PCFICH and PHICH of CRS.

Specifically, the terminal device that narrow beam for example weak overlay area in the specific region into first community on SCC can be used sends CRS, PDCCH, PCFICH and PHICH.Since the running time-frequency resource that different common signal channels are occupied in transmission is not identical, for example PDCCH, PCFICH and PHICH will occupy 1-3 symbol in each subframe, and entire continuous subcarrier is occupied on frequency domain, thus can be sent using narrow beam.

For example, PDCCH almost takes the entire frequency domain resource on 1 symbol, if it cannot be sent by narrow beam, the bottleneck of system power will be stuck in the transmission of PDCCH, because even if other common signal channels are sent using narrow beam at this time, limited region can only be also covered using the PDCCH that broad beam is sent, so that the communication to terminal device affects.

And for CRS, based on PCC in carrier wave polymerization (Carrier Aggregation, CA) mechanism to the booster action of SCC, even if the terminal device of those weak overlay areas does not receive CRS on SCC, also SCC is had access to, thus CSR can also be sent using narrow beam.

In addition, narrow beam can be used and scan entire cell on SCC when sending these common signal channels.The range and scan frequency the application of scanning are without limitation.

On the basis of sending CRS, PDCCH, PCFICH and PHICH using narrow beam, for other common signal channels in addition to these common signal channels, it can be sent by following methods.

Mode 1

If the type of the common signal channel is any one in following, which makes on SCC for sending whole terminal devices in the wave cover first community of the common signal channel: for sending common signal channel, P-SCH, S-SCH and BCH of CSI-RS.

Specifically, in use narrow beam on the basis of sending CRS, PDCCH, PCFICH and PHICH on SCC, broad beam can be used and send CSI-RS, P-SCH, S-SCH, BCH and other common signal channels on SCC, to guarantee that terminal device can realize synchronization on SCC, and the CSI-RS on SCC can be measured.The channel quality that CSI-RS and BCH can enable all terminals in cell obtain broadcast message and SCC on SCC is sent using broad beam, to complete the signal detection on SCC, and since the sub-carrier resources that CSI-RS and BCH is occupied are few, even if the gain of entire common signal channel will not be influenced using transmitting broad beam.

Mode 2

If the type of the common signal channel is P-SCH or S-SCH, which makes the terminal device for only covering specific region in first community on SCC for sending the wave beam of the common signal channel；If the type of the common signal channel is for sending The common signal channel or BCH of CSI-RS, then the beam angle makes on SCC for sending whole terminal devices in the wave cover first community of the common signal channel.

Specifically, in use narrow beam on the basis of sending CRS, PDCCH, PCFICH, PHICH on SCC, narrow beam can be used and send P-SCH and S-SCH, and send CSI-RS, BCH on SCC using broad beam.Due to the upper signal strong robustness of P-SCH, S-SCH, entire cell can be covered by the way of narrow beam scanning.Entire cell is scanned using narrow beam when sending P-SCH, S-SCH, the synchronizing information in cell on all users' acquisition SCC can be made, and narrow beam can promote the signal gain of P-SCH, S-SCH.

Mode 3

If the type of common signal channel is any one in following, which makes the terminal device for only covering specific region in first community on SCC for sending the wave beam of the common signal channel: for sending common signal channel, P-SCH, S-SCH and BCH of CSI-RS.

Specifically, in use narrow beam on the basis of sending CRS, PDCCH, PCFICH, PHICH on SCC, narrow beam can be used and send the common signal channels such as P-SCH, S-SCH, CSI-RS and BCH on SCC, it can send whole common signal channels on SCC using narrow beam.In such manner, it is possible to significantly more promote the covering power of corresponding weak overlay area by the gain of narrow beam.But the region that narrow beam is not covered with, corresponding user are possible to be unable to complete cell access, it is thus possible to waste the volume of business of this partial region.

Mode 4

If the type of common signal channel is the common signal channel for sending the CSI-RS, which makes on SCC for sending whole terminal devices in the wave cover first community of the common signal channel.Further, this method can also include: the network equipment on main carrier PCC, and the cell information being carried in P-SCH, S-SCH and the BCH is sent to the terminal device of first community.

Specifically, in use narrow beam on the basis of sending CRS, PDCCH, PCFICH and PHICH on SCC, broad beam can be used and send CSI-RS on SCC, and P-SCH, S-SCH and BCH are no longer sent on SCC, at this moment, the cell information in P-SCH, S-SCH and BCH can be sent on PCC.

That is, P-SCH, S-SCH and BCH can not be sent on secondary carrier SCC, and it is carried on such as cell ID of the cell information in P-SCH, S-SCH and BCH (IDentifier, ID) number, the physical layer ID value of cell, cell ID group number (Cell Group ID) etc., can be allocated to terminal device by PCC.Here with PCC in CA to the booster action of SCC, by PCC by the information configuration being carried in SCC on P-SCH, S-SCH and BCH to the terminal device of cell.Due to being the same cell, terminal device has been able to carry out information exchange with the network equipment on PCC, thus the information of these on SCC can be issued terminal device by PCC.So as to avoid the transmission of P-SCH, S-SCH and BCH on SSC, system power is farthest saved.

Optionally, as one embodiment, which further includes the direction of the launch for the transmission power and/or the wave beam that send the wave beam of the common signal channel.

Further, the network equipment determines the beam information for sending the common signal channel, it include: the information of network equipment channel capacity according to needed for the coverage condition of the terminal device of first community and/or the terminal device of first community, and on SCC common signal channel to be sent type, determine the beam information.

Specifically, the network equipment is before sending common signal channel, it can determine which common signal channel can be used narrow beam and be sent according to the type of common signal channel to be sent on SCC, the information of channel capacity needed for can be combined with the coverage condition of terminal device and/or the terminal device of the first community of the first community simultaneously, to determine the direction of the launch of transmission power and the wave beam for sending the common signal channel.

Such as before building a station, network planning personnel can carry out drive test on the spot, pass to entire cell the test of wave loss, so as to which the path loss situation in place each in the first community is drawn out, from the angle of the network equipment, beam angle, beam direction and the required transmission power of the wave beam for sending common signal channel on the region of emphasis covering are recognized the need for.Beam angle and transmission power determine that the terminal device on direction pointed by the wave beam can be obtained receiving the intensity of signal together.Wherein, transmission power can be received according to the terminal device in the region the corresponding flow of signal strength is estimated.In another example, network planning personnel can be according to the practical electronic map of first community, carry out system emulation, from the weak overlay area identified in simulation result in first community, and can be directly from beam angle, beam direction and the required transmission power of the wave beam for sending common signal channel obtained in emulation on the region that the network equipment needs emphasis to cover.

Or, when the statistical information of capacity needed for can obtaining the coverage condition and terminal device of the terminal device of the first community by real network statistical, i.e. in real network operational process, terminal device is according to measuring configuration to network equipment reporting measurement reports, Reference Signal Received Power (Reference Signal Received Power for example including first community, RSRP), the metrical informations such as Reference Signal Received Quality (Reference Signal Received Quality, RSRQ).Pass through the uplink signal of terminal device, the network equipment can measure the arrival bearing of the signal received, the directional information for knowing the terminal device, the metrical information reported additionally by terminal device, the network equipment are known that the signal strength and covering quality that the terminal device is received in downlink.Single terminal equipment and the result of single measurement may have deviation, but measurement result of the network equipment by statistics a period of time great amount of terminals equipment, substantially the coverage condition that can be accurately obtained on entire cell different directions, equally, according to the uninterrupted of different terminal equipment and network device communications, frequent degree, the network equipment has also just known channel capacity size required for the terminal device in first community on the region of different directions.In this way, the network equipment has just obtained the beam information of the wave beam for sending common signal channel on the region for needing emphasis to cover, such as beam angle, beam direction and required transmission power.

The network equipment be aware of on the region for needing emphasis to cover in cell for after sending the beam information of common signal channel, it can be according to these beam informations, it generates narrow beam and one or more incoherent narrow beams can be generated, and adjust these narrow beams on SCC, the terminal device for for example weak overlay area in region for making its direction that emphasis be needed to cover or the terminal device for needing channel capacity, to send the common signal channel to the terminal device of first community on SCC.Such as, some specific region range in the horizontal direction in first community is 12 degree, the range of vertical direction is 4 degree, it is oriented to 15 degree of antenna normal orientation for deviateing the network equipment and deviates 5 degree of antenna horizontal direction, for sending transmission power required for the wave beam of common signal channel as 10W on the specific region, then the terminal device that the network equipment can be generated the wave beam on SCC for sending common signal channel according to these information and the common signal channel is sent to the specific region with the power of 10W.

Since multiple narrow beams can be generated on SCC, transmission power can be allocated between multiple narrow beams on SCC simultaneously, so system can carry out power distribution between different beams, be not construed as limiting here to allocation algorithm according to the terminal device of entire cell and the distribution relation of flow.In this way, the network equipment is under the premise of system total power is certain, can in coordinated allocation first community on the region of different directions for sending the power resource of common signal channel.It, can be by power distributions more in general power to the wave beam for being directed toward the direction when the network equipment knows that the terminal device of the specific region in first community on some direction needs to enhance signal strength and channel capacity.
