Embodiment
Basic thought of the present invention is: Microcell is carried on notifying user equipment UE in dedicated signaling by the configuration information of PHICH; And/or, determine when UE need switch between Microcell (pico community) and macrocell (macro community), the configuration information of PHICH is carried on and in hand off signaling, notifies UE.
For making the object, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
The main system broadcast (MIB) of community all sends at the 0th work song frame, therefore the MIB of macro community can send with the MIB of pico community simultaneously, for pico community in cell coverage expansion (CRE, Cell Range Extension) UE in region, when receiving the MIB of pico community, can produce larger interference, Reference Signal Received Power (the RSRP of Dang Liangge community particularly, when Reference Signal Receiving Power) signal strength signal intensity differs over 9dB, the UE of pico community may solve pico mib information hardly, thereby cannot obtain the necessary system broadcast message in MIB, for example can not obtain Physical HARQ Indicator Channel (PHICH, the information of Physical HARQ Indicator Channel) carrying, also just can not obtain the information of symbol lengths of the shared subframe of down control channel of indicating cell.
Fig. 1 is the flow chart of the system message sending method of the embodiment of the present invention, and as shown in Figure 1, system message sending method of the present invention comprises the following steps:
Step 101, pico base station is carried on PHICH configuration information in dedicated signaling, to send to the UE in pico community.
The present invention may be subject to the interference of macro base station community for above-mentioned MIB signaling just and the UE that can not be positioned at pico community receives, and therefore, by being originally carried in MIB PHICH configuration information, is carried in dedicated signaling notice to the UE of pico community.
Step 102, UE receives after dedicated signaling, returns to dedicated signaling and receives response message, to make pico base station learn whether UE receives the dedicated signaling that this has carried PHICH configuration information to pico base station.
In the present invention, can adopt Radio Resource to control (RRC, Radio Resource Control) reshuffle signaling bear PHICH configuration information and issue UE, UE starts in next system broadcast message change after receiving this PHICH configuration information constantly, adopts new PHICH configuration information to carry out the detection of PDCCH.
Those skilled in the art are to be understood that, can reshuffle the sign that PHICH configuration information is set in signaling at RRC and indicate this PHICH configuration information, or, the positional information of the PHICH of agreement carrying in advance configuration information, the positional information that the UE that gives advance notice should carry the positional information of PHICH configuration information or PHICH configuration information is carried in configuration in UE.
In the present invention, dedicated signaling is not limited to above-mentioned rrc layer signaling, also can be media access control (MAC, Media Access Control) layer signaling, for example, by media access control control unit (MAC CE, Media Access Control Control Element) design is specifically designed to the Logic Channel Identifier (LCID of notice PHICH information, Logical Channel Identify), and LCID is carried in MAC CE together with PHICH configuration information, notice is to UE.In this example, the relevant information that is about to carry PHICH configuration information is notified to UE as a kind of new logic channel, and UE intercepts this PHICH configuration information and relevant information thereof on notified logic channel.
Fig. 2 is the composition structural representation of the MAC CE of the embodiment of the present invention, as shown in Figure 2, PHICH configuration information can be carried in the MAC head of MAC CE, by the MAC head to MAC CE, carries out corresponding change.About the form of MAC CE, identical with the form of the MAC CE stipulating in existing protocol, repeat no more its format details here.
In the present invention, also can in the following manner PHICH configuration information be notified to UE.By when UE is switched to pico community from macro community, before switching completes or in handoff procedure, by hand off signaling, PHICH configuration information is notified to UE, below described in detail this technical scheme.
After UE is switched to pico community from macrocell, if UE bad channel quality, be interfered serious, may could not receive in time and upgrade PHICH configuration information, so also just cannot start to adopt detection PDCCH constantly in next system broadcast message change, and then cannot obtain new configuration information, follow-up, PDCCH message cannot correctly be detected again.Technical scheme of the present invention is mainly reused in handoff procedure at network, adopt the reconfiguration message in switching that PHICH configuration information is sent to UE in advance, like this, after UE is switched in pico community, even if can not receive the PHICH configuration information of pico cell notification, also can use the PHICH configuration information of the pico community receiving when switching to carry out PDCCH detection.
What mainly pay close attention to due to the present invention is in pico community, how to avoid UE to cause to disturb to cause UE can not receive PHICH configuration information, and therefore, the UE of mainly take is switched to pico community and introduces technical scheme of the present invention as example from macro community.If UE is switched to pico community from macro community, between macro base station and pico base station, by the interface between two base stations, transmit in advance PHICH configuration information machine and the relevant information thereof of UE, pico community sends to macro community by X2 interface by PHICH configuration information; Macro cell base station adopts switching command that this PHICH configuration information is sent to UE.
Macro community directly sends to after UE by hand off signaling by PHICH configuration information, receive the UE of PHICH configuration information after being switched to pico community, when passing through Physical Downlink Control Channel (PDCCH, while Physical Downlink Control Channel) receiving MIB or other information, use this PHICH configuration information to carry out the detection of PDCCH.
In the present invention, when being switched to pico community from macro community, likely can cause, in macro community with in the received System Frame Number in pico community (SFN, System Frame Number) difference, at UE receiving data frames, occurring mistake.Be directed to this, for the SFN in MIB, the present invention processes in the following ways:
Therefore in retaining zone, SFN is synchronous, is switched to the process of pico community at UE from macro community, can continue to obtain according to the SFN from Macro community or during access pico community SFN in MIB as the SFN in pico community.
In asynchronous region, thereby the time that issues of MIB that can be by stagger macro community and pico community is avoided the interference between MIB, but the MIB that pico community issues still may be subject to the interference of macro cell data and cannot correctly receive, therefore UE need to know the SFN difference between macro community and pico community, could in the situation that not receiving MIB, still can correctly access like this and keep synchronizeing with pico community.Therefore, from macro community, be switched to the process of pico community, macro community obtains and the SFN side-play amount of pico community or that self obtain and SFN and sub-frame offset pico community in advance by the interface between macro base station and pico base station.The SFN information of UE pico community is directly notified in Macro base station by hand off signaling, comprise the SFN side-play amount of pico community and macro community, behind UE incision community, can calculate based on the original SFN in macro community the SFN numbering of pico community like this.
PHICH configuration information and SFN relevant information while being switched to macro community about UE from pico community, also can be by relevant hand off signaling notice UE, advice method when mode and aforementioned UE are switched to macro community from pico community is basic identical, repeats no more here.
