Embodiment
As it was previously stated, in communication process, network side dispensing one logic channel of each radio bearer, and
Priority is arranged, when user terminal sends data to network side, the higher logic letter of selection priority
Road sends data.But, because the priority of different logic channels may be identical, and in communication protocol
Such a situation is not provided, when Different Logic channel priority is identical, to Different Logic channel
The transmission of data is unordered uncontrollable process, it is possible that some logic channel of priority identical
The situation of data is sent prior to other logic channels always, causes to send with equal priority to net
The data of network side can be transmitted with the unknown priority caused by without program process, and then can influence communication

So as to lift communication efficiency.
It is understandable to enable above-mentioned purpose, feature and beneficial effect of the invention to become apparent, with reference to
Accompanying drawing is described in detail to the specific embodiment of the present invention.
Fig. 1 is a kind of flow chart of data transmission method for uplink in the embodiment of the present invention.
In step s 11, the configuring request of network side is received, the configuring request includes each logic
The precedence information of channel.
Different radio bearers (Radio Bearer, RB) map to different logic channels, each logic
Channel has different Logic Channel Identifiers (RB Identification, RBID).MAC layer is in logic channel
Upper offer data transmission service, and the different types of data transmission service provided for MAC layer defines
The set of the type of one logic channel.The type of each logic channel is according to the information transmitted above
Type define.For example, logic channel RB0~RB4 transmission signalings, logic channel RB5~RB7
Transmit data.
It will be appreciated by those skilled in the art that wireless heterogeneous networks (Radio Resource Control, RRC)
The priority of every given logic channel (1-8,1 represents limit priority, 8 represent minimum) can be passed through
Control the scheduling of upstream data.Priority of logical channels is relative, that is to say, that a given priority
Data sometimes marquis be also possible to transmission, even if the data of high priority prevent it from transmitting.In order to support down
The sub-fraction of transmission block will on the transmission of the logical channel data of one priority, high priority logic channel
It is prevented from transmission.If this part is set to zero, that is, be set as absolute preferential, that is to say, that patrol
Collect on channel in order to which the transmission block supported the data transfer of low priority and be prevented from transmission is zero.
When radio bearer is set up/reconfigured, each logic channel being related to is divided in the range of 1-8
With a MAC bgical channel priorities power.At user terminal (User Equipment, UE), work as MAC
When sublayer is configured as RACH (Random Access Channel, RACH) transmission, these
Bgical channel priority power level does not select the priority level being used in MAC layer.
The precedence information of each logic channel is included in the configuring request of network side, is different logic letters
Road sets priority, the priority that user terminal (User Equipment, UE) is configured according to network side to
Network side sends data to be sent.In real network, it is different logic channels that network side occurs often
(logic channel for usually transmitting data) configuration identical priority.
In step s 12, the priority of each logic channel is confirmed according to the precedence information.
In physical layer scheduling data, it is necessary to do the instruction of High Speed Uplink Packet access transformat combination
(E-DCH Transport Format Combination Indicator, ETFCI) select, user terminal according to
The priority of network side configuration and the number traversal of logic channel have the logic channel of data, confirm that each is patrolled
Collect the priority of channel.
It is in step s 13, identical and have multiple logic channels of data to be sent if there is priority,
Then determine that the multiple logic channel forms logic channel arranged side by side.
If priority identical logic channel there are data to be sent, illustrate network side to these priority
Data no less important to be sent in identical logic channel, is required to timely send.It is same by preserving
The identification marking of the logic channel of priority, it is possible to reduce the number of times of traversal queries, improves ETFCI effect
Rate.
In specific implementation, logic channel arranged side by side can include two logic channels.For example, as the present invention
When data transmission method for uplink in embodiment is adapted to conform with the user terminal of WCDMA agreements, and row logic
Channel is generally made up of two logic channels.
In step S14, the hair of the data to be sent of each logic channel in the logic channel arranged side by side is determined
Order is sent, make it that each bgical channel priority sends the general of data to be sent in the multiple logic channel
Rate is impartial.
What is included due to logic channel arranged side by side is priority identical logic channel, data to be sent therein
No less important, if the transmission order to the data to be sent of each logic channel in logic channel arranged side by side is not carried out
Regulation, it is possible that some logic channel preferentially sends the situation of data always in logic channel side by side,
Network side is caused to provide the actual priority of the logic channel of same-priority and differ, so as to influence communication
Efficiency.
By determining the transmission order of the data to be sent of each logic channel in the logic channel arranged side by side, with
So that each bgical channel priority sends the probability equalization of data to be sent in the multiple logic channel, can
Data are preferentially sent with some logic channel for avoiding same priority always, and then can be avoided the occurrence of same
The logic channel of one priority in fact priority not caused by identical situation to the shadow of communication efficiency
Ring, so as to be conducive to lifting communication efficiency.
In specific implementation, referring to Fig. 2, each logic channel treats in the determination logic channel arranged side by side
Sending the transmission order of data can include：
Step S21, is the different index code of each logical channel assignment in the logic channel arranged side by side.
It is that the different index code of each logical channel assignment can be with logic channel arranged side by side in specific implementation
It is randomly assigned.For example, when logic channel arranged side by side is made up of two logic channels, can be at random
Two logical channel assignments 0 and 1 are used as index code.
Step S22, the current value of search index code clock, according to the current value of the index code clock
With the index code of each logic channel in the logic channel arranged side by side, determine each in the logic channel arranged side by side
The transmission order of the data to be sent of individual logic channel, when the clock cycle of the index code clock is transmission
Between be spaced (Transmission Time Interval, TTI), the current value of the index code clock is selected from
Numerical value set, the index code pair of multiple numerical value respectively with the multiple logic channel in the numerical value set
Should.
In specific implementation, according in the current value of the index code clock and the logic channel arranged side by side
The index code of each logic channel, determines the number to be sent of each logic channel in the logic channel arranged side by side
According to transmission order can include：Its corresponding index is determined according to the current value of the index code clock
Code, is designated as target index code；In current Transmission Time Interval, the logic that target index code is pointed to is sent
The data to be sent of channel.
It will be appreciated by those skilled in the art that media access control sublayer is responsible for controlling (the Random of RACH
Access Channel, RACH) TTI timing (such as：10ms radio frames grades, access
The timing of time slot is by L1 layers of control).Correspondingly, user terminal can be true in each Transmission Time Interval
Determine the transmission sequence of data to be transmitted on each logic channel in logic channel once arranged side by side, meet
The user terminal of WCDMA agreements can coordinate network side per the scheduling of 2ms or 10ms once.Index
The time-count cycle of code clock is Transmission Time Interval, often spends a time-count cycle and just current value is become
More (such as it is incremented by since initial value, reach return initial value after preset upper limit and restart to be incremented by), root
Corresponding target index code can be determined according to the current value of index code clock, and then can be determined current
Transmission Time Interval sends the logic channel of data to be sent.
In one embodiment, logic channel arranged side by side can be made up of 2 logic channels, and respectively 2 are patrolled
Channel distribution 0 and 1 is collected as index code, index code clock is using Transmission Time Interval as the cycle, circulation 0
Current value is used as with 1.When the current value of index code clock is 0, in current transmission time interval
Send the data to be sent in the logic channel that index code 0 is pointed to；When the current value of index code clock is 1
When, the data to be sent in current transmission time interval sends the logic channel that index code 1 is pointed to.
