Describe technical scheme of the present invention in detail below in conjunction with Fig. 3 to Fig. 7.
For technical scheme of the present invention is better described, the suppositive scenario of given first is as follows:
(1) terminal has all the time Yi Ge community and connects and be used for ensureing mobility.
(2) terminal is to have CA (Carrier Aggregation, carrier aggregation) or the ability that dual connectivity (doubly-linked is logical), and small cell has configured to terminal as certain Scell in a Scell (Microcell) or the SCG (Secondary Cell Group, secondary cell set) of terminal.
As shown in Figure 3, macrocell, as a Pcell (main plot) of terminal, is used for ensureing the connection of terminal in mobile process.It should be noted that the macrocell in Fig. 3 is an example as main plot, based on identical method, main plot can be also a Microcell.And small cell provides the lifting of data rate as Scell (Microcell) for terminal.This can configure to realize by the Scell in CA or DC mechanism.
How to know that in order to solve terminal how the state of small cell on/off and terminal know the problem of the time span of small cell under on state, the present invention proposes following methods:
1, when terminal does not need to carry out data interaction with Scell, Scell will enter into off state, give notice, to inform that terminal Scell will enter off state to terminal simultaneously.As shown in Figure 4, can inform that terminal Scell will enter off state by the DCI (physical layer descending control information) that is used to refer to closed condition.Under off state, Scell need to transmit can be for being terminal RRM (Radio Resource Management, RRM) measure, CSI (Channel state Management, channel condition information) obtain and synchronous etc. pilot frequency information, the Scell under off (closing) state needs notification terminal on which running time-frequency resource, to transmit these pilot frequency informations certainly.2, in the time that terminal need to be carried out data interaction with Scell, be divided into two kinds of situations:
(1) in the time being the business demand of a UL-initial (up), terminal can be by sending SR (Scheduling Request in predefined resource, dispatch request), PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel), PUSCH (Physical Uplink Shared Channel, physical uplink is shared channel) or PRACH is (Physical Random Access Channel, Physical Random Access Channel) Scell of notice in off state carry out the mutual of the distribution of resource or data.This predefined resource is to pass through RRC (Radio Resource Control by Pcell or Scell, Radio Resource control) signaling, MAC (Medium Access Control, media access control) CE (Control Element, control unit) or physical layer signaling prenotice to terminal.
(2) in the time being the business demand of a DL-initial (descending), terminal need to be known the on/off state of base station, and duration (duration) on (unlatching) state, in the present invention, propose following method and address these problems:
Method 1:Pcell is by being used for being DCI (the Downlink Control Information of public information transmission, physical layer descending control information) notification terminal Scell is about to enter the state of on, DCI for public information can be DCI format1A, 1C, the DCI of 3,3A or new definition.By defining scramble sequence or introducing new RNTI (Radio Network Temporar y Identify, Radio Network Temporary Identifier) DCI that is used to indicate the transmission of this public information is one and is used to indicate the DCI of Scell on state, wherein, as shown in Figure 5, can determine by this DCI information the state that enters in which subframe of Scell.
Method 2:Pcell is about to enter the state of on by carrying out notification terminal Scell across carrier dispatching, wherein, as shown in Figure 6, can be used to refer to which Scell of terminal and be about to enter the state of on across the CIF in the DCI of carrier wave instruction (Carrier Indicator Field, across carrier dispatching instruction territory).
Method 3:Scell informs that by the DCI that is used for doing public information transmission terminal is about to enter the state of on, can be DCI format1A for the DCI of public information, 1C, 3,3A or the DCI of new definition.When terminal detects the existence of DCI information, just think that this Scell is about to enter into the state of on.In this DCI information, can also comprise the time span of base station Scell on state.This DCI information can be to send in the cycle, and the cycle of transmission and subframe position are predefined, and Pcell or Scell can pass through RRC signaling, MAC CE or this information of physical layer signaling notification terminal.In order to reduce the complexity of terminal blind check, degree of polymerization grade and the resource location information of this DCI information also can be fixed in addition, and Pcell or Scell can pass through RRC signaling, MAC CE or this information of physical layer signaling notification terminal.
Method 4: terminal is known the state information of Scell by the blind Detecting on Scell.
After terminal has known that by above-mentioned method certain Scell is about to enter into the state of in certain subframe, also need to determine that it is the state of on that Scell starts on earth in which subframe.Can there is following method to solve.
Method 1: this time interval can be a predefined value.Pcell or Scell are by RRC signaling, and MAC CE or physical layer signaling are notified this predefined value, and terminal is after obtaining this value, and which subframe is the subframe according to first in opening calculate is last subframe in opening
Method 2: in the end started just to enter into the state of closing in a subframe in opening by physical layer signaling notification terminal after next subframe or several subframe.
Scell needed to know the CSI information of terminal before service terminal, to dispatch according to CSI information, in order to address this problem, had proposed solution below in the present invention:
Method 1:Scell is by more conservative method dispatch terminal, under this method, although terminal can be passed through DRS (Discovery Reference signaling, discovery signals) obtain the information of CSI, but because the cycle of the transmission of DRS is long, under the scene of high-speed switch small cell, CSI based on DRS measures and possibly cannot know CSI information accurately, therefore Scell can only pass through more conservative method dispatch terminal, such as Scell can just use single rank, lower MCS carrys out dispatch terminal.
Method 2:Scell utilizes the CSI information that the last measurement reports to carry out service terminal.
Method 3: terminal is transmitted to be used to indicate in the subframe that terminal is about to the DCI that enters on state and carried out the measurement of CSI and report on Scell.The configuration information of measuring based on which kind of pilot tone and pilot tone needs prior notice to terminal.
Method 4: as shown in Figure 7, enter in certain subframe before the subframe of on state transmission at Scell for carrying out the pilot frequency information of CSI measurement, this pilot frequency information can be CRS (Cell-specific Reference Signal), CSI-RS (Channel State Information-Reference signal) or other pilot tones that can measure for CSI.The position of this pilot transmission is predefined, and Pcell or Scell can pass through RRC signaling, MAC CE or the sub-frame information of this pilot tone of physical layer signaling notification transmission and the configuration information of pilot tone.
More than be described with reference to the accompanying drawings technical scheme of the present invention, by technical scheme of the present invention, terminal can be known the on off state of serving BS timely and effectively, avoids terminal to carry out invalid detection, has saved the power consumption of terminal.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
