Description
Technical field
The present invention relates to the transmission plan of the wireless signal in wireless communication system, more particularly to base
In the method and apparatus of the uplink and downstream feedback of cellular network communication.
Background technology
Traditional wireless communication system based on digital modulation mode, such as 3GPP (3rd
Generation Partner Project, third generation cooperative partner program) in cellular system, on
The transmission of row wireless signal is the scheduling based on base station.And for Next-Generation Wireless Communication Systems,
IoT (Internet of Things, Internet of Things) communications may turn into an important application
Scene.
The feature of IoT communications includes：The quantity of terminal device is very huge, and terminal device is supported
Stand-by time compared with long (power consumption is low), the cost of terminal device is relatively low etc..Traditional base
IoT is no longer desirable in the up transmission of scheduling, reason includes：
Signaling required for-descending schedulings can seriously reduce efficiency of transmission.It is especially considering that typical case
An IoT up transmission included by information bit quantity it is generally fewer.
- increases the power consumption of terminal device, reduces stand-by time.In existing system, terminal is set
For first for example, by the signalings such as SR (Scheduling Request, dispatch request), Ran Houcai
Uplink can be sent.
- increases uplink delay.In some special screnes, IoT communications need relatively low biography
Defeated delay, and the existing uplink based on scheduling can not meet this demand.
In view of the above-mentioned problems, CB (Contention Based, based on competition) uplink quilt
It is proposed, i.e. UE does not need the i.e. transmittable uplink information of the scheduling of base station.If do not occur (two
Between individual or multiple UE) conflict, then base station being capable of correct decoding uplink information.
The content of the invention
Inventor has found that one of benefit of CB uplink is by studying, when clothes needed for base station
The number of users of business is more, and when the running time-frequency resource needed for each user is smaller, and CB uplink can be with
Effectively reduce the collision of the expense and control signaling of control signaling.Then, CB uplink also can
In the presence of one it is notable the problem of, i.e., ought there are multiple UE simultaneous selections same resources to carry out up biography
When defeated, and base station has only decoded the upstream data of the part UE in the multiple UE, and sends
Corresponding HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement,
Hybrid automatic repeat-request confirms) when, the multiple UE can not know the HARQ-ACK that base station is sent
In which be their own.One simple method of above mentioned problem, it is exactly that base station is reserved enough
More resources is used for CB uplink, and base station also it is simultaneously reserved matched with ascending resource it is descending
HARQ-ACK corresponding to resource transmission.But so when no more UE carries out CB transmission, this
The resource being pre-configured with a bit can produce serious waste, and this method has also been run counter on CB in itself
The design original intention of row transmission.
In view of the above-mentioned problems, the invention provides solution.It should be noted that do not conflicting
In the case of, the feature in embodiments herein and embodiment can be arbitrarily mutually combined.For example,
The feature in embodiment and embodiment in the UE of the application may apply in base station, and vice versa.
The invention discloses a kind of method being used in the UE of radio communication, wherein, including such as
Lower step：
- step A. sends the first wireless signal in the first running time-frequency resource
- step B. detects the first signaling in the second running time-frequency resource.
Wherein, first running time-frequency resource is voluntarily selected by the UE, and described first is wireless
Signal is used for determining { the first parameter sets, the first data }.First parameter sets are used for
It is determined that at least one of { second running time-frequency resource, described first signaling }.First parameter
Set includes at least one of { the first mark, second mark }, and first mark is integer,
Second mark is integer.First signaling is physical layer signaling, first signaling by with
In it is determined that the 3rd mark.
Traditional LTE (Long Term Evolution, Long Term Evolution) and LTE-A (Long Term
Evolution Advanced, the Long Term Evolution of enhancing) in system, UE uplink is required to
Completed by base station scheduling, therefore, either pass through DCI (Downlink Control
Information, Downlink Control Information) in NDI (New Data Indicator, new data
Indicate) the descending HARQ-ACK of recessive transmission；Or pass through PHICH (Physical Hybrid
ARQ Indicator Channel, physical hybrid automatic repeat request indicator channel) dominant transmission
Descending HARQ-ACK, UE always can get on receive uplink in known running time-frequency resource
HARQ-ACK, so that it is determined that whether upstream data is received correctly by the base station.However, CB uplink,
If UE1 and UE2 simultaneous selections same running time-frequency resource simultaneously sends respective upstream data, and
Base station only detected UE1 data, and feeding back downlink HARQ-ACK.If UE2 is also received
This HARQ-ACK, then UE2 will be considered that its upstream data is received correctly by the base station, and then bring
HARQ error detections, have an impact to performance.
The design of the second mark and the 3rd mark in the above method, that is, solve above mentioned problem.Institute
It is that UE is uniquely identified to state the second mark, that is, ensures that the second mark differs corresponding to each UE
Sample.UE is also sent to base station when sending upstream data, by the second mark of oneself, and base station exists
When sending the first signaling of feedback, the 3rd mark that oneself is detected also while is fed back.If the
Three marks are identical with the second mark, then it is the UE for sending the second mark to prove this feedback,
And the upstream data for sending the UE of the second mark is correctly received；If the 3rd mark and the second mark
Know difference, then prove that this feedback is destined to other UE, and send the UE of the second mark
Upstream data is not correctly received.

At least one of two running time-frequency resources, first signaling }.It is such to be advantageous in that, when UE gives birth to
During into the first parameter sets, UE will know that where receive the first signaling, and the first signaling institute
The scrambler of use, or the information such as frequency expansion sequence, and then UE is avoided in larger running time-frequency resource
The complete signaling of blind Detecting first, reduces UE complexities, more economizes on electricity.
