Description
Technical field
The present invention relates to the radio communication based on carrier aggregation technology, particularly relating to for controlling subscriber equipment in the method from the autonomous uplink on community.
Background technology
In a communications system, subscriber equipment (UserEquipment, UE) need by timing advance (TimeAlignment, TA) and with base station (such as eNodeB) uplink synchronous is kept, namely the upward signal that all subscriber equipmenies of this base station send needs synchronous this base station of arrival, thus avoids causing severe jamming to other subscriber equipmenies.
Based on carrier aggregation (CarrierAggregation, CA) in the cordless communication network transmitted, base station can be a multiple carrier component (ComponentCarrier of user device configuration, CC), thus this subscriber equipment can communicate with base station respectively by these carrier components, one of them carrier component is called as main plot (PrimaryCell, Pcell), and other carrier components are called as from community (SecondaryCell, Scell).In each community configured for subscriber equipment, due to the difference of network design situation, the community such as had is not through trunking, and some communities may through one or more trunking, and therefore the timing advance of these communities may be different.
Specify in 3GPP (ThirdGenerationPartnershipProgram) version 10, when configuring a certain carrier component and community, autonomous uplink can be carried out by configure user equipment in base station on this community, such as periodically send interception reference signal (SoundingReferenceSignal, SRS), and define, once subscriber equipment receives the MAC (MediaAccessControl for activating a certain community, Media access contorl) control signal (ControlElement, CE), subscriber equipment should start autonomous uplink after 8ms.
Summary of the invention
Be different from each community of subscriber equipment in 3GPP version 10 and share identical timing advance, in 3GPP version 11, propose the concept of timing advance grouping (TAGroup).Each community of subscriber equipment is divided into the grouping of one or more timing advance, and identical timing advance is shared in the community in each timing advance grouping.Timing advance grouping be divided into again two classes: comprise main plot main plot grouping (PcellGroup) and do not comprise main plot from cell group (ScellGroup).
Because different communities may have different timing advances because belonging to different timing advance groupings, therefore when base station be user device configuration a certain from community time, such as should may not have effective timing advance because not belonging to the grouping of existing timing advance from community, namely there is no uplink synchronous.For this situation, RAN2 reaches an agreement: base station should first activate this new configuration from community, require that subscriber equipment to carry out Stochastic accessing on Physical Random Access Channel (PhysicalRandomAccessChannel, PRACH) to obtain effective timing advance at this from community subsequently.As mentioned above, once be activated from community, subscriber equipment starts autonomous uplink immediately after 8ms.But owing to now should not yet obtain effective timing advance from community, therefore this subscriber equipment caused serious interference from the autonomous uplink community by other subscriber equipmenies at this.
In addition, also proposed as each user device configuration timing advance timer (TimeAlignmentTimer in 3GPP version 11, TAT) scheme, divides into groups and all shares this timing advance timer from cell group in the main plot that namely this subscriber equipment is all.According to the program, timing advance timer runs based on main plot grouping, to guarantee the validity of the timing advance divided into groups in main plot.Particularly, when receiving timing advance instruction (such as, the initial setting of timing advance or the renewal of timing advance) of main plot grouping, subscriber equipment adjusts timing advance according to received instruction and restarts timing advance timer; And when receiving the timing advance instruction from cell group, subscriber equipment does not only restart timing advance timer according to received instruction adjustment timing advance.And if subscriber equipment does not receive new timing advance instruction before the timing advance timer time expires, then think that the timing advance of subscriber equipment lost efficacy, namely subscriber equipment loses uplink synchronous; If the timing advance timer time is not yet expired, then subscriber equipment think main plot grouping and be all effective from the timing advance of cell group.
Because timing advance timer only runs based on main plot grouping, thus may occur that: although in fact failed from the timing advance instruction of cell group from the timing advance of cell group because not receiving this for a long time, but timing advance timer due to constantly receive main plot grouping timing advance instruction and not yet expired, thus subscriber equipment is thought mistakenly and is still effectively from the timing advance of cell group, and then continue to send autonomous uplink, thus serious interference is caused to other subscriber equipmenies.
For above-mentioned technical problem, the object of the present invention is to provide for controlling subscriber equipment in the method from the autonomous uplink on community, to avoid or to reduce the interference of autonomous uplink to other subscriber equipmenies.
According to an aspect of the present invention, provide for controlling the subscriber equipment method from autonomous uplink community administrative in described base station in a kind of base station of the cordless communication network transmitting based on carrier aggregation, it comprises the following steps: A. judges whether described subscriber equipment has effective timing advance described from community; B. when described subscriber equipment described there is no an effective timing advance from community time, send the first message to described subscriber equipment, described first message does not send described autonomous uplink for controlling described subscriber equipment described from community.
According to a further aspect in the invention, provide in a kind of subscriber equipment of the cordless communication network transmitting based on carrier aggregation for controlling subscriber equipment in the method from the autonomous uplink on community, it comprises the following steps: a. receives from described the first message from the base station belonging to community, and described first message does not send described autonomous uplink for controlling described subscriber equipment described from community; B. based on the first received message, from community, described autonomous uplink is not sent described.
Adopt the solution of the present invention, once base station detects that subscriber equipment is not having effective timing advance from community, just control this subscriber equipment and from community, do not send autonomous uplink at this, thus the uplink communication of the uplink avoiding this autonomous to other subscriber equipmenies causes severe jamming.
