Description
Technical field
The present invention relates to the communications field, relate in particular to the sending and receiving method of a kind of BCCH (Broadcast Control Channel, BCCH).
Background technology
CELL_FACH (CELL Forward Access Channel; Cell forward access channel) state strengthens through introducing HS-DSCH (High Speed Downlink SharedChannel at the CELL_FACH state; At a high speed-and DSCH Downlink Shared Channel) strengthen the packet data transmission performance of this state, make it obtain less packet transfer delay and higher transmission rate.CELL_FACH state mechanism and enhancement mechanism also has been incorporated into UTRAN (Universal Mobile Telecommunication System Radio AccessNetwork; The global system for mobile communications wireless access network) (the UTRAN RegistrationArea Paging Channel of the URA_PCH in; Whole world terrestrial radio access registration district _ PCH) and paging and transfer of data under CELL_PCH (CellPaging Channel, the cell _ paging channel) state.
At 3GPP Rel-7 (3rd Generation Partnership Project Release7; Third generation partner program version 7) in before the version; The HS-DSCH transmission is only used DCCH (Dedicated ControlChannel down at CELL_DCH (CellDedicated Channel, cell private channel) state; DCCH) or DTCH (Dedicated Traffic Channel; Dedicated Traffic Channel) signaling on or data are mapped on the HS-DSCH transmission channel, are mapped on the HS-PDSCH (High Speed Physical Downlink Shared Channel, at a high speed-downlink physical shared channel) again.Network side is being UE (User Equipment; When subscriber equipment) setting up the relevant radio bearer of HS-DSCH; Need to dispose one group of HS-SCCH (High Speed Shared Control Channel for this UE in advance; At a high speed-shared control channel) and HS-SICH (High Speed Shared Indication Channel, at a high speed-shared indicating channel) and H-RNTI (HS-DSCH Radio Network TemporaryIdentifier, high speed descending sharing channel-Radio Network Temporary Identifier).This group HS-SCCH/HS-SICH channel is shared by a plurality of UE timesharing, and H-RNTI is the UE special use, and UE judges through the H-RNTI on the identification HS-SCCH whether this transmission points to oneself; If detect the HS-SCCH channel that points to oneself, then read the information on this HS-SCCH channel, read the data on the follow-up HS-PDSCH channel according to the indication information on this HS-SCCH channel then.
Strengthening under the CELL_FACH state, downlink signaling or data are also through the HS-DSCH/HS-PDSCH Channel Transmission.Shown in Figure 1 is non-CELL _ DCH state (comprising CELL_FACH state, CELL_PCH state and URA_PCH state) the down channel mapping relations after the enhancing in the prior art.Wherein, Originally based on FACH (Forward Access Channel; Forward access channel) CCCH (Common Control Channel, CCCH) and the BCCH (Broadcast Control Channel, BCCH) of transmission are mapped on the HS-DSCH channel; Originally based on PCH (Paging Channel; PCH) PCCH (the Paging ControlChannel of transmission; Paging Control Channel) also be mapped on the HS-DSCH channel, signaling on DCCH or the DTCH or data map are mapped on the HS-PDSCH to the HS-DSCH transmission channel again.
BCCH shown in Figure 1 is mainly used in and carries the system information that defines in RRC (Radio Resource Control, the Radio Resource control) agreement and change indication, updating system information in view of the above after UE receives.In the version before the Rel-7, this channel is mapped to the FACH transmission channel earlier, and then through S-CCPCH (Secondary Common Control Physical Channel, auxiliary CCCH) transmission.The last content of BCCH need be at whole Cell Broadcast CB, and the UE that is not in the URA_PCH state in the sub-district possibly receive.When BCCH is mapped to HS-DSCH and goes up, the special-purpose H-RNTI of BCCH of network side definition, UE comes the indication of receiving system information change through on the HS-SCCH channel, detecting this H-RNTI, and after receiving, need not feedback.Like this, in a TTI (Transmission Time Interval, Transmission Time Interval), UE need detect 2 H-RNTI, and one is the special-purpose H-RNTI of BCCH, and one is public H-RNTI or dedicated H-RNTI.The disposal ability that is limited to UE, UE can only handle a transmission block in a TTI, thereby the transmission that Node B (Node B) need guarantee the BCCH channel can not conflict to the reception of the HS-DSCH that carries public or dedicated H-RNTI with UE mutually.UE under the agreement CELL_FACH state need receive the BCCH channel at present, and the UE that has dedicated H-RNTI under the CELL_PCH state also need receive the BCCH channel.The process of transmitting of BCCH channel is as shown in Figure 2 under the single carrier case, may further comprise the steps:
201:RNC (radio network controller) sends the HS-DSCH Frame to Node B through public MAC (Medium Access Control, the medium access control) stream of Iub interface (the protocol interface name between RNC and Node B).HS-DSCH Frame under the CELL_FACH state uses HS-DSCH Frame Protocol type 2, carries the special-purpose H-RNTI of BCCH signaling data and BCCH in the Frame;
After receiving, dispatches 202:Node B through the HS-SCCH channel;
203:UE receives data after detecting the HS-SCCH that carries the special-purpose H-RNTI of BCCH on channel appointed.
In TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division-Synchronous Code Division Multiple Access inserts) system, when the CELL_FACH state is strengthened, need to consider its multicarrier characteristic.The TD-SCDMA system is a multicarrier system; A main carrier and many auxilliary carrier waves are arranged in the sub-district; The main carrier bearing public control channel; Like P-CCPCH (Primary Common ControlPhysical Channel, Primary Common Control Physical Channel), PRACH (Physical Random AccessChannel, Physical Random Access Channel), S-CCPCH, FAPCH (Fast AcknowledgementPhysical Channel; Confirm fast physical channel) and last/downlink pilot frequency channel, also can the bearing part Traffic Channel; An auxilliary carrier wave bearer service channels.For the expansion capacity, the UE that is under the CELL_FACH state after the enhancing can reside on the auxilliary carrier wave, and the UE that is under CELL_PCH state and the URA_PCH state resides on the main carrier.
At present, BCCH still only sends on main carrier, like this, under the CELL_FACH state after the enhancing, if UE resides on the auxilliary carrier wave, then can miss the reception of BCCH channel information, thereby influence follow-up operation.Under the CELL_FACH state, to the link establishment process of single UE, Node B does not lack the upper and lower civilian information of UE to the Iub mouth, so Node B and do not know the resident frequency point information of UE.In order not allow all UE to miss the BCCH channel information, can let Node B have and send BCCH information on the carrier wave of CELL_FACH resource, but this will certainly cause the waste of interface-free resources, because possibly there not be UE resident on some carrier waves at all.

Embodiment
To combine accompanying drawing and embodiment that technical scheme of the present invention is explained in more detail below.
As shown in Figure 3, the basic design that the present invention adopts is: preserve all resident information that the carrier wave that is in the UE under the CELL_FACH state is arranged on the Node B; When need sent BCCH, RNC sent the HS-DSCH Frame to Node B on a public MAC stream of Iub interface, wherein carried the special-purpose H-RNTI of BCCH signaling data and BCCH; After Node B receives, respectively to all resident carrier wave transmission BCCH signaling data and special-purpose H-RNTI of BCCH that the UE of CELL_FACH state is arranged.
With TD-SCDMA multicarrier system is example, and network side sends the method for BCCH, may further comprise the steps:
301, set up a plurality of public MAC streams at Iub interface, be used to strengthen the HS-DSCH transmission under the CELL_FACH state.The corresponding carrier wave of each public MAC stream, a carrier wave can flow by corresponding one or more public MAC;
302, the UE that is in idle pulley initiates connection request through Node B to RNC on main carrier; After RNC receives; Confirm it is transferred to the CELL_FACH state; Then distribute a resident carrier wave (carrier wave of promptly working) and the special-purpose H-RNTI of this UE for this UE; And return RRC through Node B to this UE through the corresponding public MAC stream of main carrier and connect and set up message, carry public H-RNTI, RRC in the HS-DSCH Frame and connect promising this UE distributes in the message the dedicated H-RNTI and the information of resident carrier wave set up.UE receive RRC connect set up message after, the carrier wave that moves to the RNC appointment is resident.Network side is just transferred on this resident carrier wave the transmission of the downlink data of this UE.That is to say that follow-up RNC is on the pairing public MAC stream of the resident carrier wave of this UE, to send to NodeB for this UE sends data, wherein carries the dedicated H-RNTI of this UE.For Node B; It is after receiving a Frame under the CELL_FACH state; Can judge the corresponding carrier wave of H-RNTI the Frame from the public MAC stream at Frame place, promptly just can note the incidence relation of the H-RNTI of the corresponding carrier wave of this public MAC stream and this UE;
In this step, we have provided the method that a kind of Node B is known the work carrier wave of UE, and then can know the UE of the resident CELL_FACH of the having state of which carrier wave.But can be not limited to this method, such as RNC can which carrier wave of Periodic Notice Node B on the resident UE that the CELL_FACH state is arranged.
303, when need send BCCH, RNC sends the HS-DSCH Frame through one on the Iub interface public MAC stream (can but be not limited to be the corresponding public MAC stream of main carrier) to Node B, wherein carries the H-RNTI of BCCH signaling data and BCCH special use;
Wherein, this HS-DSCH Frame is the Frame in the HS-DSCH Frame Protocol type 2 that defines in the Iub mouth agreement, is used for transmission HS-DSCH data under the CELL_FACH state; The BCCH signaling data can but to be not limited to be that system information changes indication.
304, after Node B receives, on above-mentioned each resident carrier wave, send HS-SCCH respectively, wherein carry the H-RNTI of above-mentioned BCCH special use according to the incidence relation of all resident carrier waves of preserving on it and the H-RNTI of UE;
For the mode that Node B sends HS-SCCH, can have following two kinds: mode one: Node B is synchronized transmission HS-SCCH on each resident carrier wave; Mode two: Node B sends HS-SCCH with the predetermined time difference on each resident carrier wave.
305, Node B sends HS-PDSCH respectively according to the incidence relation of the H-RNTI of all resident carrier waves preserved on it and UE on above-mentioned each resident carrier wave, wherein carries the BCCH signaling data.
After step 302, when the UE that has been assigned with resident carrier wave need be when current resident carrier wave 1 moves to another resident carrier wave 2, RNC need notify the resident carrier wave of this UE of Node B to change, Notification Method can for following any one:
Method one: RNC sends the HS-DSCH Frame on the public MAC stream of resident carrier wave 2 correspondences, wherein carry the H-RNTI of this UE, can carry or not carry data; Remove the resident carrier wave 1 of preservation on it and the incidence relation of the H-RNTI of this UE after Node B receives, set up the incidence relation of this H-RNTI and resident carrier wave 2;
Method two: RNC notifies the resident carrier wave of this UE of Node B to change in a newly-increased message of chain of command, comprises the information of H-RNTI and the new resident carrier wave of this UE in this message at least, the information of promptly resident carrier wave 2; Remove the resident carrier wave 1 of preservation on it and the incidence relation of the H-RNTI of this UE after Node B receives, set up the incidence relation of this H-RNTI and resident carrier wave 2.
Like this; When Node B receives the HS-DSCH Frame of the special-purpose H-RNTI correspondence of BCCH; Obtain the resident carrier information that UE under the enhancing CELL_FACH state is arranged all resident carrier waves that Node B can preserve from this locality and the incidence relation of the H-RNTI of UE, then the BCCH signaling data in the synchronized transmission HS-DSCH Frame on these resident carrier waves.
More special is the transmission of public H-RNTI.The sign that public H-RNTI is provided with in order to identify UE when being the descending CCCH message of transmission.Message and cell update acknowledge message are set up in RRC connection when CCCH message comprises initial the access, also comprise periodic cell update message, and the message when wherein initially inserting is always transmitted on main carrier; Periodic cell update message is then sent on the resident carrier wave of UE.When UE received initial access message, UE also need detect the BCCH channel, thereby concerning Node B, must on main carrier, send the BCCH channel.Node B can discern public H-RNTI, thus to public H-RNTI can it goes without doing the record of incidence relation of resident carrier frequency and H-RNTI.
Except that being in the CELL-FACH state, when UE is in CELL_PCH or CELL_DCH state following time, also can adopt said method to send BCCH, specifically describe as follows:
(1) for the UE that is under the CELL_PCH state.
In present agreement, have special-purpose H-RNTI and also need receiving system information change Indication message if be in UE under the CELL_PCH state.Because these UE are decided to be approximately and are only resided on the main carrier; Thereby receive the Frame (Frame Protocol type 3 is that the HS-DSCH that is exclusively used in the PCH state under transmits usefulness) of HS-DSCH Frame Protocol type 3 as Node B; And receive to as if during the special-purpose H-RNTI of BCCH, Node B will only send the BCCH channel on main carrier.
(2) for the UE that is under the CELL_DCH state.
In present agreement, the UE that is under the CELL_DCH state does not need the indication of receiving system information change.When the UE under the CELL_DCH state in the sub-district also need receive the BCCH channel, can adopt the method for the invention, Node B only sends BCCH information on the resident carrier wave that UE arranged.When being in the CELL_DCH state, Node B has whole state informations of UE, comprises resident carrier information, so Node B will transmitting system information change indication on the carrier wave at the UE place of distributing the HS-DSCH transfer resource.
In addition; When simultaneously resident when UE a plurality of CELL_FACH states under, UE or the UE CELL_FACH state and CELL_DCH state under a plurality of CELL_DCH state are under arranged on certain carrier wave, Node B on this carrier wave to carry HS-PDSCH that the same system information change indicates can a transmission once.
In addition, the UE with multicarrier receiving ability may receive the system information variation indication on a plurality of carrier waves simultaneously, and whether UE can distinguish through the content in these indications be that same system information variation is indicated.
Preceding text have explained under the CELL_FACH state that network side sends the method for BCCH.And in the UE side, the method that is in the UE reception BCCH under the CELL_FACH state comprises, and: UE only detects HS-SCCH on own resident carrier wave; After in detecting HS-SCCH, carrying the special-purpose H-RNTI of BCCH, receive the BCCH signaling data (changing indication) on the corresponding HS-PDSCH channel like system information.
For saving the power consumption of UE under the CELL_FACH state, can, introduce UE DRX (Discontinuous Reception, discontinuous reception) operation when receiving the BCCH signaling data.In this case, the UE with dedicated H-RNTI is monitors downlink channel on certain interval only, promptly carries the HS-SCCH channel of BCCH dedicated H-RNTI.At present, the DRX operating parameter under the CELL_FACH state is the amount of cell-level, mainly comprises: DRX cycle length, activation length, unit all is a subframe.UE and the Node B both sides that need make an appointment receive and dispatch the subframe numbers SFN ' of system of HS-SCCH channel.As shown in Figure 4, UE can detect the HS-SCCH channel on following subframe:
SFN '=side-play amount+n*DRX Cycle Length+m
Wherein, Side-play amount is different because of UE, can make the UE that is in the sub-district under the CELL_FACH state not receive HS-SCCH at one time like this, and the mode that Node B and UE are good by appointment calculates the value of this side-play amount; For example, a kind of method is: dedicated H-RNTI mould DRX cycle length; N is the integer between 0～8191, and the value of guaranteeing SFN ' is in the scope of whole subframe numbers value; M is the integer between 0～(activating length-1).
At present, the content that DRX discusses is only to the reception of the HS-SCCH that carries the UE dedicated H-RNTI, and the reception of the down control channel that relates to of uplink service, do not relate to the reception of the HS-SCCH that carries the special-purpose H-RNTI of BCCH.In system in the past, BCCH only sends at the TS0 time slot, and the HS-SCCH channel sends at TS3～TS6 time slot, and UE can not influence the content that UE reads the TS0 time slot to the DRX operation of HS-SCCH channel.The BCCH signaling data will send on the HS-PDSCH channel now, and corresponding HS-SCCH channel is also at TS3～TS6 time slot.
Therefore, in above-mentioned steps 304, Node B can send BCCH (that is, send on the BCCH system information conversion indication) in the DRX of the UE under being in CELL_FACH state reception opportunity.The UE that this step has guaranteed to be under the DRX pattern can in time receive information, and the power consumption of having saved UE.After having adopted this kind sending method, as shown in Figure 5, under the DRX pattern, the method for reseptance of BCCH may further comprise the steps:
501, the UE that is under the CELL_FACH state that has activated the DRX receiving mode only detects HS-SCCH on resident carrier wave in DRX reception opportunity; When UE is not in the DRX reception during opportunity, do not detect HS-SCCH;
502, after detecting the HS-SCCH that carries the special-purpose H-RNTI of BCCH, UE receives the BCCH signaling data on the corresponding HS-PDSCH channel.
For the UE that is under the CELL_PCH state, when it did not have special-purpose H-RNTI, system information conversion indication brought UE through beep-page message; After UE had dedicated H-RNTI, it also can equally, also need detect the special-purpose H-RNTI of BCCH through HS-PDSCH channel receiving system information conversion indication.Because the acquiescence of the UE under the CELL_PCH state all is in the DRX pattern that activates; Therefore when it has dedicated H-RNTI and network side when also being employed in DRX and receiving the method for sending BCCH in opportunity, method of its reception BCCH can be identical with the above-mentioned method that is in the UE reception BCCH under the CELL-FACH state.
Can find out through the foregoing description; Solved because the receiver of UE is limited in one's ability; Can not receive the problem of 2 data on the carrier wave simultaneously,, make the BCCH channel on all need receive the resident carrier wave of UE of BCCH channel, to send through the transmission/method of reseptance of BCCH channel provided by the invention; UE only need intercept the BCCH on the own resident carrier wave; Eliminate the restriction of UE receiving ability aspect, guaranteed all UE all the have the ability transmission of detection at any time BCCH channel and the power consumption of having saved UE.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
