Description
Technical field
Embodiments of the invention relate generally to wireless communication system.More specifically, embodiments of the invention relate to the method and apparatus for scheduling user's set in the wireless communication system supporting dual link.
Background technology
Because low power nodes can bring the gain of capacity amplification and blind spot covering aspect, more and more study in deployment emphasis being pointed to the small cell (smallcell) covered by low power nodes and enhancing.Here, low power nodes can be small base station, and its example includes but not limited to the low power base station such as Pico, Femto.In 3GPP R12, new research item " Small Cell Enhancements for E-UTRA and E-UTRANHigher-layer aspects " (" strengthen for the small-cell of the high-rise aspect of E-UTRA and E-UTRAN) " to be given the ratification and one of them emphasis is the dual link (dual connectivity) will supporting macrocell (being provided the community of covering by macro base station) layer and slight region layer.
In wireless communications, need to set up different radio bearers so that the serving data for having different service quality (" QoS "), and user face data (" User Plane ", be called for short " UP ") will at Data Radio Bearer (" Data Radio Bearer ", be called for short " DRB ",) above send and chain of command (" Control Plane ", being called for short " CP ") data will in Signaling Radio Bearer (" Signaling Radio Bearer " is called for short " SRB ") upper transmission.For the situation of dual link, subscriber equipment (" User Equipment ", be called for short UE) will be connected with two base stations simultaneously, one of them base station such as can be macro base station and another base station can be such as small base station, and term " base station " alternatively can be called the Node B (" eNB ") of Node B and evolution with the evolution of radio communication here.For this reason, need to consider how how to configure under dual link and to dispatch UE.
According to Current specifications, E-UTRAN needs to observe the UE Radio Access Capability parameter sent by signaling when configuring and dispatch UE.UE Radio Access Capability parameter refers to UE-classification (UE-Category) and the parameter independent of field ue-classification, and these parameters comprise PDCP (" the PDCP ") parameter that UE supports, wireless spread-spectrum technology (" RLC ") parameter, the physical layer parameter of UE support and radio frequency (RF) parameter etc. of UE support that UE supports.
When UE first time access network, network should obtain UE Radio Access Capability.Such as, network it will be appreciated that the classification of UE, and then it can distribute suitable radio resource for this UE.The current UE having 8 kinds, following table illustrates the downlink physical layer parameter value arranged by field ue-classification.
The downlink physical layer parameter value that table 1. field ue-classification is arranged
Suppose that a UE is the 5th classification, the maximum number of the DL-SCH transmission block bit that it receives in a TTI is 299552.Therefore, consider the disposal ability of UE, network can not in a TTI by the bit transfer more than 299552 to this UE.
Before 3GPP version 12, there is a medium education (" Medium Access Control " is called for short " MAC ") for performing centralized scheduling to UE in the base station of network side.Because be centralized scheduling, this MAC can guarantee that the radio resource distributing to UE can not more than UE Radio Access Capability.
In order to spectrum efficiency and mobility are improved, currently in small cell strengthens, introduce the scheme of dual link.For the ease of understanding, Fig. 1 exemplarily illustrates the UE all keeping with the macro base station providing macrocell to cover and the small base station providing small cell to cover being connected, and namely UE is in the pattern of dual link.Nonideal back haul link is there is between macro base station and small base station.The obvious delay (one way is approximately 2ms to 60ms) of this back haul link will cause cannot applying under dual link scene the centralized scheduling of UE of being performed by MAC.Therefore, in dual link, adopt distributed scheduling to be a feasible scheme to UP, and RAN2 is discussing the possible protocols framework for dual link now.Fig. 2 illustrates a kind of possible user plane framework.As can be seen from Figure 2, the S1 interface coming from core net terminates in macro base station MeNB place, and small base station SeNB is received the data of one or more DRB based on Xn interface (or strengthen X2 interface) from MeNB and transmitted to UE by corresponding RLC, MAC and physical layer (not shown).In this protocol infrastructure, independently MAC is used for performing distributed scheduling.Usually, macro base station or small base station only can guarantee that the resource of distributing in its side obeys the restriction owing to UE disposal ability, and macro base station or small base station can not be guaranteed can both obey the restriction owing to UE disposal ability for whole Resourse Distribute of both sides both it.In this case, how to guarantee that the disposal ability of UE is the problem needing to solve.
