Embodiment
In order to more clearly 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, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
Set forth a lot of detail 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 by the restriction of following public specific embodiment.
Fig. 1 shows Microcell according to an embodiment of the invention dynamic switch conversion method and systematic difference scene schematic diagram.
A kind of application scenarios of example in this article, as follows:
1) terminal has community all the time and connects and be used for ensureing mobility.
2) the terminal ability that there is carrier aggregation or be bi-directionally connected, and small cell(Microcell) as the secondary community of a 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 the process of movement, and small cell as Scell for terminal provides the lifting of data rate.This can pass through CA(carrier aggregation) or DC mechanism in Scell configuration realize.
When terminal has transfer of data, Scell is in the state of on, is normally Terminal for service.When terminal does not have data to need mutual, so Scell can enter the state of off at once.At this, by the step shown in Fig. 2, whole flow process is described.
Step 202:macrocell configures and activates as the Microcell of secondary community and to the Microcell of this terminal to terminal, can multiplexing before CA(carrier aggregation) in flow process
Step 204: terminal and small cell carry out normal data interaction.
Step 206: macrocell or Microcell find signal by RRC signaling or the DS(of other mode notification terminal Microcell) configuration information.
Step 208: when Microcell judges that its terminal of serving not to have a data interaction with it, Microcell determines to enter into off state (this can in several ways or algorithm realization).Microcell notification terminal will enter off state.
It should be noted that, Fig. 2 is an example, and the signaling that notification terminal will enter off state is not only and can be sent by Microcell, equally also can be sent 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 being used for doing public information transmission) such as 1A, 1C.By defining a kind of public RNTI(Radio Network Temporary Identifier newly), be used for representing DCI(Downlink Control Information) indicate Microcell to enter off status.As the FFF5 in following table.Terminal, after receiving the Downlink Control Information 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 being used for doing public information transmission), such as 1A, 1C.By the mode of scrambling, two scramble sequence can be defined, two scramble sequence as shown in Figure 3.One of them scramble sequence instruction Microcell is about to the state entering off, and another instruction Microcell is about to the state entering on.By using different sequence pair schedule information DCI to carry out scrambling, terminal can know the change of Microcell state.
Method 3: macrocell or Microcell will enter off state by physical layer signaling notification terminal Microcell.This physical layer signaling is that the existing DCI format being used for doing public information transmission is as 1A, 1C.Different from first two mode, need to revise the information of carrying in the transfer of data indicated in this DCI format.In this information, directly indicate the state variation of Microcell, can also transmit the duration of other information such as off state simultaneously, state transition information such as to transmit 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 sending DS(finds signal).
Step 214: terminal, based on discovery signal, RRM(RRM is carried out in Microcell) behavior measure, synchronous etc., and give macrocell measurement feedback.
Step 216: if terminal has data to need with Microcell alternately, then need the state that Microcell enters out, and enter open state to terminal notification Microcell, advice method can have following methods to realize:
Method 1: macrocell will enter open state by physical layer signaling notification terminal Microcell, this physical layer signaling is the existing DCI format such as 1A, the 1C that are used for doing public information transmission.By defining a kind of public RNTI newly, be used for representing that this DCI indicates the change of Microcell state.As above the FFF4 in table.Terminal, after receiving the DCI with FFF4 scrambling, just knows that Scell is about to the state entered out.
Method 2: macrocell will enter open state by physical layer signaling notification terminal Microcell.This physical layer signaling is the existing DCI format such as 1A, the 1C that are used for doing public information transmission.By the mode of scrambling, can define two scramble sequence, one of them scramble sequence instruction Scell is about to the state entering pass, and another instruction Scell is about to the state entered out.By using different sequences to carry out scrambling for schedule information DCI, terminal can know the change of Microcell state.
Method 3: macrocell will enter open state by physical layer signaling notification terminal Microcell.This physical layer signaling is the existing DCI format such as 1A, the 1C that are used for doing public information transmission.Different from first two mode, need to revise the information of carrying in the transfer of data indicated in this DCI format.The state variation of direct indicating terminal Microcell in this information, can also transmit the information such as the duration of other information such as off status simultaneously.
Method 4: macrocell will enter open 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 signal, when terminal receives the information of Microcell indicating status change, so terminal just knows that Microcell is about to the state entered out.
In order to realize this mechanism, macrocell or be in the Scell of open state can by RRC signaling, the DCI information of indicating status change which subframe under off status will be transmitted in MAC CE or physical layer signaling notification terminal Microcell.Terminal in corresponding subframe while reception DS, also can be got off the DCI receives information of indicating status change.
Method 6: by sending the up signalings such as SR, SRS, PUCCHPUSCH or PRACH, terminal can notify that Microcell has data to need alternately.Resource shared by transmission notice can be predefined or got off by network configuration.
By above-mentioned flow process, the state of Microcell can be known timely by various mode terminal.After the state knowing Microcell, can measure accordingly and other behaviors, such as, time under the state that Microcell is in pass, the discovery signal that terminal sends based on Microcell carries out RRM behavior measure.When terminal needs to carry out data interaction with Microcell, can notify that Microcell has data to need by up signaling method mutual, thus make Microcell enter open state, can be about to enter open state in notification terminal Microcell in time by the various modes mentioned herein, equally, when Microcell enters off status, also can be about to enter off status by the timely notification terminal Microcell of various mode, therefore effectively can support the switch state of dynamic Microcell, thus obtain optimum system gain.
