Specific implementation mode
As previously mentioned, in the larger communication scenes of signal fadeout, terminal is difficult to get the signal or letter of complete and accurate Breath, and then be difficult to access network.
In embodiments of the present invention, by detecting multiple wave beams from network side, and the packet of the multiple wave beam is combined The signal and/or information of identification code containing same cells (Cell Identity, Cell ID), can obtain diversity gain, so that The signal of the broadcast type after must combining and/or the information of channel bearing can support accessing terminal to network.
It is understandable to enable above-mentioned purpose, feature and the advantageous effect of the present invention to become apparent, below in conjunction with the accompanying drawings to this The specific embodiment of invention is described in detail.
Fig. 1 is a kind of flow chart of method for network access in the embodiment of the present invention.
In step s 11, multiple wave beams from network side are detected, the wave beam is used to carry the signal of broadcast type And/or channel.
In specific implementation, multiple wave beams from network side can be the wave beam of different moments different directions, can also It is different moments unidirectional wave beam.
In access procedure, in order to make up additional path loss, Beamforming technology may be used, such as may be used and sweep wave Beam (Beam sweeping) technology.(analog) or mixing (hybrid) beam forming can be simulated in beam technique by sweeping Technology sends the signal and/or channel of broadcast type, you can to send the wave beam of different directions in turn at different times so that Terminal (User Equipment, UE) can receive at least partly wave beam.Beam technique is swept to be otherwise known as multi-beam method (Multi-beam approach), and the method for sweeping wave beam is not used and is known as simple beam method (Single-beam approach)。
Network side can repeat to send the identical wave beam in the direction (Repetition) in different moments, these wave beams correspond to Same cell；The wave beam of the different directions of corresponding same cell can also be sent.These wave beams can be configured identical cell Identification code and different wave beam identification code (Beam identity, Beam ID).User equipment differentiation at this time can distinguish difference The different beams of cell.
Network layer can also use multicast Single frequency network (Multi/Broadcast Single Frequency Network, MBSFN) technology sends the identical multiple wave beams of content by multiple cells of the same cell ID of correspondence in synchronization.This A little wave beams can be configured identical cell ID and identical wave beam identification code, and user equipment, which cannot distinguish between, at this time comes from The same wave beam of different community.
Terminal detects multiple wave beams from network side during accessing network, can be that detection is more from network side The wave beam of a cell, each cell can have the wave beam of multiple directions and multiple moment.In specific implementation, correspondence is same small The wave beam in area can include identical cell ID.
One in the specific implementation, at least can be that time-division and/or frequency division are multiple between synchronizing signal in the multiple wave beam ；At least can be time-division and/or frequency division multiplexing between wave beam level reference signal in the multiple wave beam；It is described more At least can be time-division and/or frequency division multiplexing between broadcast channel in a wave beam；Public control in the multiple wave beam At least can be time-division and/or frequency division multiplexing between channel.
In a non-limiting example, the time-frequency location of broadcast channel can pre-define, and with it is synchronous The time-frequency location of signal has fixed offset.For example, situation one (broadcast channel is time-multiplexed with synchronizing signal)：Broadcast channel It is consistent with the bandwidth of synchronizing signal, broadcast channel and synchronizing signal frequency location having the same；Broadcast channel continues n symbol Number, and immediately synchronizing signal on broadcast Channel Time.Situation two (broadcast channel and synchronizing signal frequency division multiplexing)：Broadcast channel It is consistent with the duration of synchronizing signal, and broadcast channel and synchronizing signal time location having the same；Broadcast channel accounts for According to the frequency location other than synchronizing signal.
The time-frequency location of common control channel can be Master Information Block pre-defining or by broadcast channels carry common Indicated.For example, situation one (common control channel is time-multiplexed with broadcast channel)：Common control channel and broadcast channel Bandwidth is consistent, common control channel and broadcast channel frequency location having the same；Common control channel continues m symbol, and And immediately broadcast channel on the common control channel time.Situation two (common control channel and broadcast channel frequency division multiplexing)：It is public Control channel is consistent with the duration of broadcast channel, and meta position when common control channel and broadcast channel are having the same It sets；Common control channel occupies the frequency location other than broadcast channel.
More specifically, there can be following typical synchronizing signal, broadcast channel and the common control channel predefined Time-frequency location situation.Situation one：Synchronizing signal, broadcast channel and common control channel time division multiplexing, and with identical Bandwidth, be followed successively by synchronizing signal, broadcast channel and common control channel in the time domain.Situation one is relatively suitble to the terminal of narrowband Access, synchronizing signal, broadcast channel and common control channel can repeat to send on a wave beam, and terminal passes through above-mentioned group The reception of conjunction mode carrys out access system.Situation two：Synchronizing signal, broadcast channel and common control channel frequency division multiplexing, in frequency domain On be followed successively by broadcast channel, synchronizing signal and common control channel；One wave beam corresponds to a time interval, emits x wave beam Continue x time interval,.Situation two is relatively suitble to the terminal access in the broadband on high band, synchronizing signal, broadcast channel and public affairs Control channel can in turn be sent on multiple wave beams altogether, and terminal is by the reception of combination above-mentioned come access system.Example Such as, for situation one：In multiple subframes of t*N symbol or time slot, control channel accounts for t*n symbol, synchronizing signal, broadcast Channel and common control channel time division multiplexing account for remaining t*N-t*n symbol.For situation two：In a son of M symbol In frame or time slot, control channel accounts for n symbol, synchronizing signal, broadcast channel and common control channel frequency division multiplexing, a wave beam A corresponding symbol, emits M-n wave beam, occupies M-n symbol.
In specific implementation, the signal of broadcast type and/or channel include following at least one：Synchronizing signal, broadcast letter Road, common control channel and wave beam level reference signal.The signal and/or channel of broadcast type are for providing accessing terminal to network Required information.
Wherein, the wave beam level reference signal can be used for temporal frequency synchronization and/or the wave beam rank of wave beam rank Wireless resource management measure.
One in the specific implementation, the wave beam is additionally operable to carrying moment index value, at the time of sending the wave beam with instruction. Since unidirectional wave beam can be sent in different moments, terminal knows the delivery time of the wave beam by the index value, from And system timing information can be obtained, such as 10 milliseconds of timing informations in LTE system, in this way, could Timing Synchronization to system In, carry out subsequent operation.Wherein, the index value can be used as wave beam identification code.
In step s 12, the signal and/or information for including same cells identification code from the multiple wave beam are combined, With the information of the signal of the broadcast type after being combined and/or channel bearing.
As previously mentioned, in certain scenes, such as in 5G communications, due to being communicated by high band, signal fadeout is larger. As a result, when detecting and decoding the signal and/or channel of broadcast type of beams carry, only once from single wave beam, often difficulty obtains The signal of the broadcast type of complete and accurate and/or the information of channel bearing are obtained, and then is difficult to access network.
By combining the signal and/or information for including same cells identification code from multiple wave beams, diversity can be obtained Gain, so that the signal of the broadcast type and/or the information of channel bearing that are obtained after combination can support terminal to connect Enter network.
In step s 13, according to the signal of the broadcast type after combination and/or the information access net of channel bearing Network.
In specific implementation, the multiple wave beams of the detection from network side can be repeated detection, be distributed in combination and come It carries out during the signal comprising same cells identification code and/or information of the multiple wave beam, detection every time can be A wave beam from network side is carried out.
Such as first synchronizing signal can be detected, it is different not from cell ID in multiple wave beams of network side When with cell, it may be determined that cell to be accessed, and determine the time-frequency location of the synchronizing signal of cell to be accessed；In the more of network side When a wave beam is from cell ID identical cell, determine that the cell is cell to be accessed, and determine the same of cell to be accessed Walk the time-frequency location of signal.
After choosing cell to be accessed, multiple wave beams from network side can be detected again, at this point, detection Multiple wave beams can be multiple wave beams from cell to be accessed.Multiple wave beams from cell to be accessed either direction not Same wave beam can also be the identical wave beam for repeating to send in different moments in direction.
Multiple wave beams from cell to be accessed can include identical cell ID, carry identical broadcast type Signal and/or channel.Terminal can combine the signal and/or information of multiple wave beams from cell to be accessed.
Combination can also be distributed in from the multiple of cell to be accessed to the detection of multiple wave beams from cell to be accessed During the signal and/or information of wave beam, repeatedly multiple wave beams from cell to be accessed can be detected, carry out one Secondary or multiple combination, until the signal of the broadcast type obtained after combination and/or the information checking of channel bearing are correct, eventually End can be according to the signal of the broadcast type obtained after combination and/or the information access network of channel bearing.
Or repeatedly multiple wave beams from cell to be accessed can also be detected, until reaching preset stopping item Part.The stop condition can be time conditions, or detection times condition.
The process for choosing cell to be accessed is further described below in conjunction with Fig. 2.
In the step s 21, synchronizing signal described in multiple wave beams from network side is detected.
Synchronizing signal in multiple wave beams from network side can correspond to a cell ID, or can also be right The detection of synchronizing signal in multiple wave beams should can be completed in preset time in multiple cell IDs.
In step S22, the detected value of the synchronizing signal of corresponding same cells identification code is combined, to obtain one or more Combined result, the cell ID for the different community that the different combined results corresponds to.
Cell ID can be carried in synchronizing signal, the detected value of synchronizing signal can be by terminal in a time-frequency position It sets, attempts to obtain using preset cell ID is to the multiple wave beams progress received related.Terminal can be attempted to pre- If the synchronizing signal from each wave beam received in the time carries out correlation, to obtain multiple detected values.
