Description
Technical field
It is the present invention relates to a kind of communications field, more particularly to a kind of to keep the user equipment connected at least two base stations
Sending method, user equipment and the base station of ascending control information.
Background technology
In long term evolution (LTE, Long Term Evolution) system, base station can be that user equipment (UE) configuration is more
A descending carrier and/or multiple up-link carriers, i.e. carrier wave polymerize.When user equipment feed back Physical Downlink Shared Channel (PDSCH,
Physical Downlink Shared Channel) corresponding ACK/NACK when, can a moment, while feed back it is multiple under
The ACK/NACK of the PDSCH of row carrier wave.
For example, for being at most only capable of supporting the user equipment of 2 descending carriers, Physical Uplink Control Channel format can configure
The channel selection (channel selection) of 1a/1b (PUCCH format 1a/1b) carrys out loading ACK/NACK；For can be with
It supports the user equipment of more descending carriers, can configure PUCCH format 3 to carry the ACK/ of most 5 descending carriers
NACK。
Ascending control information (UCI, Uplink Control Information) can also include letter in addition to ACK/NACK
Channel state information (CSI, Channel State Information), scheduling request (SR).One moment, UE may send one
Kind UCI, it is also possible to while sending a variety of UCI.For example, user equipment can individually send ACK/NACK, CSI or SR, but
ACK/NACK and CSI can be sent simultaneously, either can send CSI and SR simultaneously or send ACK/NACK and CSI simultaneously, or
Person sends three simultaneously.
Different UCI is combined, and PUCCH format are different used by user equipment.For example, being configured with format
3 user sends SR using format 1, when sending SR and ACK/NACK simultaneously, then may be used when only sending SR
Format 3 is sent.
Also, PUCCH format used by user equipment and whether only there is PDSCH transmission also related on main carrier
System.For example, being configured with the user equipment of format 3, if only there is PDSCH transmission on main carrier, format 1a/1b are used
Otherwise feeding back ACK/NACK uses 3 feeding back ACKs of format/NACK.
In addition, with the development of user equipment especially radio-frequency apparatus, although still there is certain customers' equipment to be unable to support
It is sent while managing Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel) and PUCCH, but has portion
Divide user equipment that can support to send PUSCH and PUCCH simultaneously.For this kind of user equipment, UCI be PUCCH or
It is sent in PUSCH, and there are many possible combinations.
If for example, only ACK/NACK either CSI when PUCCH loading ACKs/NACK or CSI, if existing ACK/NACK
There is CSI again, then PUCCH loading ACKs/NACK, PUSCH carries CSI, and influences of the UCI to PUSCH data transmissions is reduced with this.
For multiple carrier waves of a user device configuration controlled by a base station in the polymerization of existing carrier wave, it can
To think that the circuit (Backhaul) of multiple intercarriers is ideal.Therefore, base station is clearly to know on each carrier wave whether have
PDSCH transmission, to whether there is corresponding ACK/NACK to send, if there is corresponding CSI to send, therefore can explicitly know use
Family equipment is that mode used or what format are sent.Although being likely to occur on the certain carrier waves of user equipment missing inspection
PDCCH, and missing inspection PDSCH, cause user equipment send mode it is different from the hypothesis that base station receives, but this possibility compared with
It is low, base station can't be influenced too much.
With the continuous development of small base station, in Rel-12, will occur there are multiple small bases in a macro base station coverage area
The scene stood.The area coverage of each small base station is smaller, and quantity is more.Small base station can occupy different frequency points from macro base station,
Identical frequency point can also be occupied.Circuit between small base station and macro base station can be ideal, i.e., time delay very little or can neglect completely
Slightly disregard, and transmittability is strong.More typically nonideal, i.e., propagation delay time is larger and transmittability is limited.
Fig. 1 is the schematic diagram that user equipment keeps connection with macro base station and small base station.If as shown in Figure 1, user equipment
It can keep connecting with small base station and macro base station simultaneously, then user equipment can be operated in a kind of carrier wave similar under different eNB
It polymerize (inter-eNB).
It should be noted that above to the introduction of technical background be intended merely to it is convenient to technical scheme of the present invention carry out it is clear,
Complete explanation, and facilitate the understanding of those skilled in the art and illustrate.Cannot merely because these schemes the present invention
Background technology part is expounded and thinks that above-mentioned technical proposal is known to those skilled in the art.
Invention content
But inventor has found to belong to different eNB from macro base station due to small base station, and circuit is non-ideal, base station is basic
The related information of other base station Real-Time Schedulings can not possibly be obtained.Such as macro base station can not know each subframe downlink in small base station
The dynamic dispatching of PDSCH or the dynamic dispatching of uplink PUSCH, therefore can not know corresponding ACK/NACK transmission, can not also it know
The location information etc. of road PUSCH.
