Description
Technical field
The present invention relates to wireless communication technology, particularly relate to control channel transmission technique.
Background technology
In the direction that the uplink direction of wireless communication system, i.e. user terminal are launched to network side, user terminal needs
Transmit different upstream control signalings to network side.Such as, long-term in 3G (Third Generation) Moblie partner program project
Evolution (3GPP LTE, 3rdGeneration Partnership Project Long Term Evolution) in system, this
A little upstream control signalings have confirmation/deny (ACK/NACK, ACKnowledgement/Non-ACKnowledgement) information,
Channel quality instruction (CQI, Channel Quality Indicator) information, multiple-input and multiple-output (MIMO, Multiple
Input Multiple Output) relevant aerial information, and uplink scheduling request instruction information (SRI, Scheduling
Request) etc..
CQI information, for notifying the downlink channel quality situation of user terminal institute perception, to help network side (base
Stand) carry out link circuit self-adapting and frequency selective scheduling.Communication system generally carries out the feedback of CQI according to the distinctive cycle.
For communicating pair, ACK/NACK information, confirms that communication is the most successful.At FDD (FDD, Frequency
Division Duplexing) in system, if user terminal the most only receives a code word, then user terminal is the most anti-
Present an ACK/NACK；If user terminal once have received multiple code word, for example with MIMO technology, then user terminal
Can once feed back multiple ACK/NACK.In time division duplex (TDD, Time Division Duplexing) system, user is eventually
End can also once feed back multiple ACK/NACK of data about multiple descending reception a up moment.Generally,
When user terminal is correctly detecting downlink data, meeting feeding back ACK, if terminal thinks that the downlink data detected is wrong, meeting
Feedback NACK.
SRI information, is for the user terminal on base station synchronization, when it has the up transmission of data latency
Time, needing to send dispatch request instruction information (SRI, Scheduling Request Indicator) to base station, base station receives
After resource request instruction information, if distribution running time-frequency resource is to user terminal, just transmission resource allocation information is to user terminal, opens
Beginning uplink.
Whether send CQI information and ACK/NACK information independent of transmitting uplink data, the two upstream control signaling it
Between whether send the most separate.Generally, CQI information is only had to send or only ACK/NACK information needs at certain user terminal
During transmission, will be transmitted on the specific resource distributed for each of which, corresponding specific resource is called this user's
CQI channel or ack channel.SRI information is relevant with transmitting uplink data, sends the most before data is transmitted, its transmission letter
Road becomes SRI channel.
In 3GPP LTE system, up employing single-carrier frequency division multiple access access technology with reduce signal peak-to-average force ratio, but
The information simultaneously transmitted is needed to be sent in identical frequency resource only in same operating process.In order to maintain up single load
Wave property, when a user terminal has upstream control signaling to be sent simultaneously, cannot use respective specific resource simultaneously
Transmit.At this moment there is upstream data to need to send according to transmission upstream control signaling the most simultaneously, be divided into again two kinds of situations.
Below as a example by ACK/NACK information and CQI information are for needing the upstream control signaling sent simultaneously, division this two
Prior art in the case of Zhong:
In the case of not having upstream data to transmit, in order to safeguard the uplink single-carrier property of 3GPP LTE system simultaneously,
Prior art is that ACK/NACK information and CQI information are multiplexed into the CQI channel resource of this user in a time multiplexed way is enterprising
Row transmission.The situation of one and multiple ACK/NACK is not differentiated between: (a) is only ACK/ with reference to Fig. 1, the ACK/NACK in Fig. 1
The situation of NACK, (b) is the situation of only CQI, and (c) is the situation simultaneously having ACK/NACK and CQI.In Fig. 1, NULL represents not
Transmit any information.
In the case of having upstream data to transmit simultaneously, ACK/NACK and CQI sum on corresponding data channel respectively
It is transmitted according to after wrapping multiplexing together.
Inventor finds, during due to various control signaling common transport, the stock number of use reduces, many through this of multiplexing
The performance planting control signaling all can be affected, and the above-mentioned sending mode simultaneously sending various control information and each self-information
Individually the sending mode of transmission is different, and system design is complex.
Summary of the invention
The main technical problem to be solved in the present invention is to provide launching technique and the device of a kind of signal of communication, in a certain use
When family terminal has various control signaling to be sent simultaneously, moreover it is possible to keep single-carrier property, ensure less control signaling simultaneously
The loss of energy.
Embodiment of the present invention provides the launching technique of a kind of communication information, has multiple control at a certain user terminal simultaneously
When information processed is to be sent, the present invention, according to the value of wherein certain control information, selects the one of this various control information at it
Transmit or be multiplexed on data channel resource on the channel resource of itself and be transmitted.
Present invention also offers discharger corresponding with above-mentioned launching technique.
The single-carrier property requirement that 3GPP LTE system is up i.e. can be met by this simple process, simultaneously will not
Cause big performance loss.This programme can ensure the transmission of transmitted breath to greatest extent when user terminal energy constraint
Performance, and different control channel can with independent design, be independent of each other, system realizes simple.
