A kind of method, system and equipment of communication

Technical field

The present invention relates to wireless communication technology field, particularly a kind of method of communication, system and equipment.

Background technology

Along with the evolution of technology and the increase of data service, the concept of small cell (small-cell) proposes and is shown great attention to.Small cell has less coverage and lower transmitting power conventionally, and by smallcell being deployed in to the nearer position of distance users, for example indoor and hot spot region, can promote user's data rate.

According to current research, the type of small cell is mainly divided into three kinds, only there is the small cell of independent attribute, only there is the small cell and the small cell with independence and dependent double attribute of dependent attribute, the signal that Figure 1A and Figure 1B have provided respectively small cell dependent and worked alone.

Comprise the local evolution base station of Local eNB() and the grand evolution base station of Macro eNB() heterogeneous network deployment scenario as shown in Figure 1 C.Wherein Macro base station provides grand covering, and Local eNB provides focus to cover in grand coverage.Fig. 1 C heterogeneous network deployment scenario is for the network architecture shown in upper figure, if according to current mechanism, UE(subscriber equipment) while moving, may constantly carry out the handover operation between Macro cell and Local cell in Macro cell coverage.Cause communication to interrupt for fear of frequent switching, a kind of mode is exactly to allow the simultaneously resource of polymerization Local eNB and Macro eNB of UE, but RRC connection maintains under Macro eNB, Local resource is only for communication, be chain of command user face isolation technics, separate also referred to as carrying.

At LTE-A(LTE-Advanced, strengthen Long Term Evolution) in system, the peak rate of system is than LTE(Long Term Evolution, Long Term Evolution) system has huge raising, requires to reach descending 1Gbps, up 500Mbps.Therefore, LTE-A system needs extending user equipment available bandwidth, by same eNB(evolution base station) under multiple continuous or discrete carrier aggregation together, be UE service, so that required speed to be provided, as shown in Fig. 1 D simultaneously.These carrier waves that condense together are called again member carrier (CC, Component Carrier).Each community can be a member carrier.In order to guarantee backwards compatibility, each carrier wave maximum is no more than 20MHz.

In carrier aggregation, one of them member carrier is configured to main carrier (Pcell or PCC), subscriber equipment receives PDCCH(Physical Downlink Control Channel on main carrier, Physical Downlink Control Channel) public search space (CSS) and search volume (UESS), wherein public search space is for sending the PDCCH of scheduling common control channel order, for example broadcast, paging etc., UE search volume is for sending for user's dispatch etc.Other member carriers except main carrier all become auxiliary carrier wave (Scell or SCC), and subscriber equipment only receives PDCCH UE search volume on auxiliary carrier wave, does not receive PDCCH public search space.And the blind check number of times of subscriber equipment blind check PDCCH UE search volume on Pcell and Scell is identical.

According to the service condition of frequency spectrum, small cell will mainly use high band (for example 3.5GHz or more than), and Macro cell for example mainly uses, compared with low-frequency range (2GHz or following).Therefore, carrying mask work mode can be combined with carrier aggregation, and the chain of command of subscriber equipment connects to maintain compared with low-frequency range is served by Macro, and the connection of user's face maintains higher frequency band and served by small cell.In this scheme, conventionally by the CC(Component Carrier being connected with Macro, member carrier) as Pcell, subscriber equipment is main receiving system broadcast, paging, RRC signaling etc. on this CC; Network is using the CC being connected with small cell as Scell simultaneously, and subscriber equipment only receives user's face control signal, data etc. on this CC.

Separate with C/U in carrier aggregation in the scheme combining, only transmit chain of command signaling on Pcell, a little high-rise control signals always do not send, and therefore the upper total data volume of Pcell is lower; Scell is for transmission user face control signal, data etc.Because small cell base station distance subscriber equipment is nearer, signal quality is better, for the user of high throughput demands, a large amount of communications is all carried out on Scell, and therefore the upper total data volume of Scell is very high.And subscriber equipment need to carry out a large amount of insignificant Pcell monitorings at present, thereby cause unnecessary energy consumption, and reduced the dispatching flexibility on Scell.

In sum, subscriber equipment need to carry out a large amount of insignificant Pcell monitorings at present, thereby causes unnecessary energy consumption, and has reduced the dispatching flexibility on Scell.
