Embodiment
For addressing the deficiencies of the prior art, the embodiment of the present invention proposes a kind of allocation plan of multi-user's MIMO parameter.In this scenario, according to this ability information, the ability information that RNC receiving terminal reports, judges whether terminal possesses MU-MIMO ability; When RNC judges that terminal possesses MU-MIMO ability, the serving BS to terminal and terminal sends MU-MIMO information.
At 3G (3rd Generation, G mobile communication) in system, RACH is the channel of a capacity constraint, and the data that this channel can carry have the upper limit, if increase new cell in the channel, the vacant bit of this channel will correspondingly reduce.But there is redundancy in the partial cell in RRC connection establishment request message in TD-SCDMA (Time Division-Synchronous Code Division MultipleAccess, TD SDMA) system.Such as, cell " HS-PDSCH (High-Speed Physical Downlink Shared Channel; high-speed physical downlink shared channel (HS-PDSCH)) inCELL_FACH " and " Support of common E-DCH (Enhanced Dedicated Channel strengthens dedicated channel) " represent whether terminal supports that HS-DSCH and E-DCH transmits in the cell--fach state in the protocol respectively.For TD-SCDMA system, because " HS-PDSCH inCELL_FACH " ability and " Support of common E-DCH " ability are bindings, ability that if terminal possesses " HS-PDSCH in CELL_FACH ", then possesses " Support of common E-DCH " ability simultaneously, therefore, there is redundancy in the implication of above-mentioned two cells, causes unnecessary bit consumption in RACH.In the embodiment of the present invention, the combination of existing cell can be used to represent, and terminal possesses MU-MIMO ability, to reduce the bit consumption of RACH.
Below in conjunction with the accompanying drawing in the present invention, carry out clear, complete description to the technical scheme in the present invention, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
As shown in Figure 1, be the collocation method flow chart of the MU-MIMO in the embodiment of the present invention one, comprise the following steps:
Step 101, the terminal under idle condition sends RRC connection establishment request (RRCConnection Request) message to RNC.
Wherein, carry the ability information of terminal in RRC connection establishment request message, this ability information comprises cell " Support of common E-DCH (supporting common E-DCH) " and " Access stratum releaseindicator (instruction of Access Layer version) ".
Step 102, RNC sends wireless link request (Radio LinkSetup Request) message to the serving BS of terminal, wherein, according to RRC connection establishment message, RNC judges that terminal possesses MU-MIMO ability after, for this terminal configuration MU-MIMO configuration parameter, and being carried on the serving BS being sent to this terminal in wireless link request message by Iub interface, this Iub interface is the interface between RNC and base station.
Particularly, when the ability information of carrying in the RRC connection establishment request message that terminal sends comprises cell " Support of common E-DCH " and " Access stratum release indicator ", and the version number of " Accessstratum release indicator " indicating terminal is version number 10 or later release number, such as, during version number 11, RRC determines that terminal possesses MU-MIMO ability, and the serving BS to terminal sends wireless link request message.
Wherein, the MU-MIMO configuration parameter of carried terminal in wireless link message, serving BS can dispatch this terminal according to this MU-MIMO configuration parameter.The user that above-mentioned parameter can comprise MU-MIMO to, can be up direction and/or down direction.When the user of MU-MIMO is to during for up direction, serving BS uses E-AGCH type 2 form dispatch terminal; When the user of MU-MIMO is to during for down direction, serving BS uses HS-SCCH type 4 form dispatch terminal.Above-mentioned wireless link request message can also carry information start-up time of MU-MIMO, serving BS can according to information start-up time of this MU-MIMO, MU-MIMO operation is started, according to the user of the MU-MIMO of MU-MIMO configuration parameter instruction to dispatch terminal in corresponding time.
In addition, when carrying cell " Support ofcommon E-DCH " and " Access stratum release indicator " in the RRC connection establishment request message that terminal sends, but the version number of " Access stratum releaseindicator " indicating terminal be version number 8 or version number 9 time, RNC determines that this terminal does not possess MU-MIMO ability, and the ability information that RRC connection establishment request message carries is used to indicate terminal whether supports HS-DSCH and E-DCH transmittability in the cell--fach state.
The embodiment of the present invention also can use new cell to represent that terminal possesses MU-MIMO ability, such as, and MU-MIMO ability sign.When the ability information of terminal to report comprises MU-MIMO ability sign, RRC judges that terminal possesses MU-MIMO ability, and this MU-MIMO ability sign represents that terminal possesses MU-MIMO ability.
Step 103, serving BS returns wireless link response (Radio Link SetupResponse) message to RNC.
Particularly, after serving BS receives the wireless link request message from RNC, wireless link response message can be returned to RNC, for terminal sets up special wireless link.
Step 104, RNC sends RRC information to terminal, wherein, if according to RRC connection establishment message, RNC judges that terminal possesses MU-MIMO ability, is then that the MU-MIMO configuration parameter of this terminal configuration is carried on RRC information and sends to this terminal.
Particularly, RNC, can by sending RRC information by this terminal configuration in CELL_DCH state to terminal after receiving the wireless link response message that serving BS returns, and indicating terminal starts corresponding MU-MIMO ability.Carry the MU-MIMO configuration parameter that RNC is this terminal configuration in this RRC information, terminal can monitor corresponding channel according to this MU-MIMO configuration parameter.The user that above-mentioned MU-MIMO configuration parameter can comprise MU-MIMO to, when the user of MU-MIMO is to during for up direction, terminal monitors E-AGCH according to E-AGCH type 2 form; When the user of MU-MIMO is to during for down direction, terminal uses HS-SCCH type 4 form to monitor HS-SCCH.
Can also carry information start-up time of MU-MIMO in RRC information, terminal according to this of information, can start MU-MIMO operation in the corresponding time start-up time, and corresponding channel is monitored in the MU-MIMO direction according to the instruction of MU-MIMO configuration parameter.Usually, terminal and serving BS need starting control channel form corresponding to MU-MIMO in the same time mutually, in this case, RNC can carry identical entry-into-force time point in the RRC information sent to terminal and the wireless link request message sent to serving BS.
In this step, RNC can be RRC connection establishment message to the RRC information that terminal sends, and also can be other RRC reconfiguration message, and such as, RB sets up message, RB reconfiguration message, transmission channel reconfiguration message and physical channel reconfiguration message etc.
Embodiments of the invention comprise following advantage, because whether the combination indicating terminal that have employed existing signaling and existing cell possesses MU-MIMO ability, solve the problem that MU-MIMO ability is resolved and MU-MIMO configures, specification has been carried out to the configuration of MIMO parameter.In addition, by optimizing the cell in signaling, the bit consumption of RACH is decreased.Certainly, the arbitrary product implementing embodiments of the invention might not need to reach above-described all advantages simultaneously.
