Breath, needs that terminal is notified to transmit these pilot frequency informations on which running time-frequency resource certainly in the Scell under off state.At this point,
Pcell or Scell needs to notify the terminal Scell that will enter the state of off by physical layer signaling.For this
All terminals for servicing in Scell, above-mentioned signaling can be to be sent respectively for each terminal, is also possible to for all ends
End simultaneously transmission.Certainly, Pcell or Scell can also pass through RRC (Radio Resource Control, radio resource control
System) signaling, MAC (Medium Access Control, media access control) CE (Control Element, control unit) letter
Enable notice terminal Scell that will enter the state of off.
As shown in figure 4, Pcell is such as used for the DCI information of cross-carrier scheduling in some subframe by physical layer signaling
Or the DCI information notice terminal Scell 1 for common control information has entered off state, it should be noted that Fig. 4
A kind of only exemplary method can also have other embodiments under same method, for example Pcell is sent on subframe n
RRC signaling, MAC CE physical layer signaling are such as used for the DCI information of cross-carrier scheduling or for common control informations
DCI information notice terminal Scell 1 has entered off state, and Scell is the shape that off is just entered in the n-th+x subframes
State, this certain x are to need to notify to terminal.
Method 2: method as shown in Figure 5, Scell pass through RRC signaling, MAC CE or physical layer letter in some subframe
The DCI information notice terminal Scell 1 such as the DCI information of cross-carrier scheduling or for common control information is enabled to enter
Off state is arrived, it should be noted that Fig. 5 is a kind of exemplary method, there can also be other implementations under same method
Scheme, such as Scell send RRC signaling on subframe n, and MAC CE or physical layer signaling are such as used for cross-carrier scheduling
DCI information or DCI information notice terminal Scell 1 for common control information have entered off state, and Scell is
The state of off is just entered in the n-th+x subframes, this certain x is to need to notify to terminal.
It, can be by object if entering off state with physical layer signaling notice Scell in above-mentioned two methods
It directly indicates that the physical layer signaling is used to refer to show that Scell enters off state in reason layer Signalling Information Field, definition can also be passed through
It scramble sequence or introduces new RNTI and is used to indicate the DCI of public information transmission and be one and be used to indicate Scell switch shape
The DCI of state transformation, as shown in table 1, if the RNIT value that terminal receives a physical layer signaling is FFF5, it is determined that the physical layer
Signaling is the signaling that an instruction Scell enters off state.
