More terminals.
To introduce more frequency spectrum resources to meet the performance index requirements constantly lifted, opened from 3GPP Release13
Begin, introduce LAA (Licensed-Assisted Access to Unlicensed Spectrum) system, realize and awarding
Power frequency spectrum (such as：The frequency spectrum of LTE system) auxiliary under use unauthorized frequency spectrum resource (such as 5GHz frequency spectrum).In LAA systems
In system, due to introducing unlicensed spectrum resource, therefore LAA systems need to follow unlicensed spectrum on the basis of LTE system
Some mechanism.Use of the various countries for unlicensed spectrum at present is provided that some of countries and regions define respectively
Need to use LBT (listen before talk) mechanism, i.e. listem-before-talk mechanism in unauthorized frequency range, carrying out data transmission
Before, the state of first monitor channel whether idle, the transmission of data message and control information is carried out if channel idle, it is no
Then without transmission.
The process of channel-monitoring is also referred to as clear channel assessment (CCA) (ClearChannelAssessment, referred to as CCA).
Exemplary, it is assumed that the power of a base station measurement to channel is not less than -62dBm, then the website thinks that channel is busy；It is low
In -62dBm, then the website thinks that channel is idle.
A kind of exemplary mode whether idle as the state of monitor channel, specifically, whether having around UE detections
Miscellaneous equipment just sends data in destination channel., can be in next monitoring if the target channel is taken by miscellaneous equipment
Cycle continues to monitor when arriving, and can also no longer be monitored according to instruction；If listening to the channel resource free time, the UE can be accounted for immediately
With the destination channel.Channel holding time is a fixed value, and the fixed value is the sub-frame of uplink of SRS configuration informations configuration
The time span of last symbol, it is contemplated that UE is reported to the transfer process of Channel Detection in SRS, can be examined in subsequent channels
One silence period of setting before location is put.Preferably, if listening to the channel resource free time, a random number L conduct can be generated
Back off time, in this back off time, continue to monitor destination channel, if detecting, L destination channel is in idle condition,
Back off time terminates, while the UE cans take destination channel progress SRS and reported.If UE detects that channel status is non-
Idle (such as being taken by other UE), then equipment is unable to busy channel within this cycle, then the UE can be waited until next
Continue to detect in the fixed position in cycle.
Another exemplary mode whether idle as the state of monitor channel, specifically, working as UE needs to report SRS
When, trigger initial detecting.If UE initial detectings are in idle condition to destination channel, you can the destination channel is taken, and
One Channel holding time T is pre-configured with by base station；If UE initial detectings are busy to destination channel state, one can be generated
Individual postponement (defer period) time in cycle, if still detecting that destination channel is done in postponement cycle time, continue to give birth to
Into a postponement cycle time.UE detects that channel status can take destination channel afterwards to be idle in L detection time, accounts for
It is T with the destination channel time.
The scheduling mode that LAA systems are supported is divided into self scheduling and cross-carrier scheduling.In LAA systems, due to LBT results
Change is frequent, needs to use cross-carrier scheduling to be needed to the greatest extent in LBT successes to improve scheduling success ratio when LBT fails as far as possible
Amount uses self scheduling to avoid excessive signaling consumption.However, whether terminal supports that cross-carrier scheduling is by Radio Resource control
The ConnectionReconfiguration fields of channel (Radio Resource Control, RRC) signaling processed configure
, because the renewal time of RRC signaling is longer, this flexibility that is semi-statically configured is not strong so that systematic function declines.
Wherein, the communication system shown in Fig. 1 supports the dynamic translation of scheduling mode, and the communication system shown in Fig. 1 is LAA systems
System.Base station can be defined as the scheduling mode that terminal carries out uplink data scheduling according to preset rules, and scheduling mode includes self-regulated
Degree or cross-carrier scheduling；Further, base station can send the control information carried for indicating scheduling mode to terminal, more
