Embodiment
In order more clearly to understand above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.It should be noted that, in the situation that not conflicting, the feature in the application's embodiment and embodiment can combine mutually.
A lot of details are set forth in the following description so that fully understand the present invention; but; the present invention can also adopt other to be different from other modes described here and implement, and therefore, protection scope of the present invention is not subject to the restriction of following public specific embodiment.
Fig. 1 shows the application scenarios schematic diagram of Microcell according to an embodiment of the invention dynamic switch conversion method and system.
A kind of application scenarios of example in this article, as follows:
1) terminal has all the time Yi Ge community and connects and be used for ensureing mobility.
2) terminal has the ability of carrier aggregation or two-way connection, and small cell(Microcell) as the secondary community of Scell(of terminal) or SCG has configured to terminal.
As shown in Figure 1, macrocell(macrocell) as a Pcell(main plot of terminal), be used for ensureing the connection of terminal in mobile process, and small cell provides the lifting of data rate as Scell for terminal.This can be by CA(carrier aggregation) or DC mechanism in Scell configure to realize.
In the time that terminal has transfer of data, the state of Scell on, normally for terminal provides service.In the time that terminal does not have data needs mutual, Scell can enter the state of off at once so.At this, by the step shown in Fig. 2, whole flow process is described.
Step 202:macrocell configures to terminal and activates as the Microcell of secondary community and to the Microcell of this terminal, can be multiplexing before CA(carrier aggregation) in flow process
Step 204: terminal and small cell carry out normal data interaction.
Step 206: macrocell or Microcell are by RRC signaling or the DS(discovery signals of other mode notification terminal Microcell) configuration information.
Step 208: in the time that Microcell judges that the terminal of its service does not have data interaction with it, Microcell determines to enter into off state (this can be in several ways or algorithm realize).Microcell notification terminal will enter off state.
It should be noted that, Fig. 2 is an example, and notification terminal will enter the signaling of off state and be not only and can send by Microcell, equally also can send by macrocell.
What notification terminal Microcell entered off state can have following methods:
Method 1: macrocell or Microcell will enter off state by physical layer signaling notification terminal Microcell, this physical layer signaling is the existing DCI format(Downlink Control Information that is used for doing public information transmission) for example 1A, 1C.By defining a kind of new public RNTI(Radio Network Temporary Identifier), be used for representing DCI(Downlink Control Information) indicate Microcell to enter off status.As the FFF5 in following table.Terminal, after the Downlink Control Information of receiving with FFF5 scrambling, just knows that Scell is about to enter the state of off.
Method 2: macrocell or Microcell will enter off state by physical layer signaling notification terminal Microcell.This physical layer signaling is the existing DCI format(Downlink Control Information that is used for doing public information transmission), for example 1A, 1C.By the mode of scrambling, can define two scramble sequence, two scramble sequence as shown in Figure 3.One of them scramble sequence instruction Microcell is about to enter the state of off, and another instruction Microcell is about to enter the state of on.By using different sequences to carry out scrambling to schedule information DCI, terminal can be known the variation of Microcell state.
Method 3: macrocell or Microcell will enter off state by physical layer signaling notification terminal Microcell.This physical layer signaling be the existing DCI format that is used for doing public information transmission as 1A, 1C.Different from first two mode, need to revise the information of carrying in the transfer of data of indicating in this DCI format.The direct state variation of instruction Microcell in this information, simultaneously can also transmit the duration of other information such as off state, and state-transition information such as transmits at the information in which subframe.
Step 210: terminal pins is to transfer of data feeding back ACK/NACK.
Step 212: Microcell enters off status, but send DS(discovery signals).
Step 214: terminal, based on discovery signals, is carried out RRM(RRM on Microcell) behavior measure, synchronous etc., and give macrocell measurement feedback.
Step 216: if terminal has data need to follow Microcell mutual, the state that needs Microcell to enter out, and enter out state to terminal notice Microcell, advice method can have following methods to realize:
Method 1: macrocell will enter out state by physical layer signaling notification terminal Microcell, this physical layer signaling is the existing such as 1A of DCI format that is used for doing public information transmission, 1C.By defining a kind of new public RNTI, be used for representing the variation of this DCI instruction Microcell state.As above the FFF4 in table.Terminal, after the DCI receiving with FFF4 scrambling, is just known the state that Scell is about to enter out.
Method 2: macrocell will enter out state by physical layer signaling notification terminal Microcell.This physical layer signaling is the existing such as 1A of DCI format that is used for doing public information transmission, 1C.By the mode of scrambling, can define two scramble sequence, one of them scramble sequence instruction Scell is about to enter the state of pass, the state that another instruction Scell is about to enter out.By using different sequences to carry out scrambling for schedule information DCI, terminal can be known the variation of Microcell state.
Method 3: macrocell will enter out state by physical layer signaling notification terminal Microcell.This physical layer signaling is the existing such as 1A of DCI format that is used for doing public information transmission, 1C.Different from first two mode, need to revise the information of carrying in the transfer of data of indicating in this DCI format.The direct state variation of indicating terminal Microcell in this information, can also transmit other information simultaneously such as information such as duration of off status.
Method 4: macrocell will enter out state by RRC signaling or MAC CE notification terminal Microcell.
Method 5: terminal can detect DCI information by Microcell in the subframe of transmission discovery signals, in the time that terminal is received the information of Microcell indicating status variation, terminal is just known the state that Microcell is about to enter out so.
In order to realize this mechanism, macrocell or the Scell that is in out state can pass through RRC signaling, and the DCI information that indicating status changes will be transmitted in which subframe under off status in MAC CE or physical layer signaling notification terminal Microcell.In terminal can receive DS in corresponding subframe, the DCI information also indicating status being changed receives.
Method 6: terminal can be by sending SR, SRS, it is mutual that the up signalings such as PUCCHPUSCH or PRACH notify Microcell to have data to need.The shared resource of transmission notice can be predefined or be got off by network configuration.
By above-mentioned flow process, can know timely the state of Microcell by variety of way terminal.After knowing the state of Microcell, can measure accordingly and other behaviors, for example Microcell in close state under time, terminal based on Microcell send discovery signals carry out RRM behavior measure.In the time that terminal need to be carried out data interaction with Microcell, can notify Microcell to have data to need by up signaling method mutual, thereby make Microcell enter out state, in time notification terminal Microcell be about to enter open state by the variety of way of mentioning herein, equally, in the time that Microcell enters off status, also can be about to enter off status by the timely notification terminal of variety of way Microcell, therefore can effectively support the switch state of dynamic Microcell, thereby obtain optimum system gain.
