Description

The method and eNB of DRX parameter adjustments are carried out in long evolving system
Technical field
The present invention relates to 3GPP (The 3rd Generation Partnership Project, third generation affiliate Plan) propose Long Term Evolution (Long Term Evolution, referred to as LTE) field, more particularly to one kind in LTE system The method and eNB (evolved Node of middle progress DRX (Discontinuous Reception, discontinuous reception) parameter adjustment B, evolved base station).
Background technology
The broadband wireless high speed data transfer that LTE is provided is designed using 1ms short frame, it is meant that UE (User Equipment, user equipment) need to intercept Physical Downlink Control Channel (Physical Downlink Control per frame Channel, referred to as PDCCH), therefore consumption UE that can be drastically electricity.In LTE, it is proposed that DRX mechanism, purpose exist In allowing the UE of no data transfer to turn off wireless receiver in the cycle according to as defined in agreement, so as to reach the mesh of power saving 's.
The DRX mechanism of above-mentioned agreement description be faced with UE power savings amplitude and good QoS (Quality of Service, Service quality) ensure between consider.Specifically, if turning off the overlong time of wireless receiver, the response speed of business It is relatively slow, Consumer's Experience may be influenceed；If the time for turning off wireless receiver is too short, UE power saving amplitude will be influenceed, it is unfavorable In UE endurance.
LTE protocol leading 3GPP is described in detail in RRC_CONNECTED (wireless heterogeneous networks connection) state Lower UE DRX mechanism.RRC (Radio Resource Control, radio resource control) can be controlled by configuring Whether UE uses DRX, so as to control whether UE intercepts PDCCH C-RNTI (Cell Radio Network Temporary Identifier, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI), TPC-PUCCH-RNTI (transmission power control-physical uplink control letters Road-Radio Network Temporary Identifier), (transmission power control-Physical Uplink Shared Channel-wireless network faces TPC-PUSCH-RNTI When identify) and Semi-Persistent Scheduling C-RNTI (semi-persistent scheduling C-RNTI).
If the UE in RRC_CONNECTED states is configured with DRX and enabled, UE DRX parameters specify during not Need to intercept PDCCH, and Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH) and Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH) does not have data Transmission, UE at this time are in SLEEP (dormancy) state.And if needing to intercept PDCCH during DRX parameters are specified, this When UE be in ON (work) state.If being configured without DRX to enable, UE needs to intercept PDCCH always, that is, is constantly in ON shapes State, to determine whether there are data to need to transmit on PDSCH or PUSCH.
It is two kinds of long period (longDRX-Cycle) and short cycle (shortDRX-Cycle) that DRX, which is divided to, and its short cycle is write from memory Recognize and do not enable.If UE configurations DRX is enabled, within the DRX short cycles, in opening RF modem (radio frequency moulds during ON states Formula), to intercept PDCCH.When detect PDCCH instruction PUSCH or PDSCH have data to be transmitted when, eNB will for this UE Start a drx-InactivityTimer (the static timers of DRX), so that the UE persistently detects to PDCCH during this period Listen.If drx-InactivityTimer is overtime, UE enters SLEEP states.In order to increase being quick on the draw for UE data transfers Degree, if UE is having that data are to be transmitted in not listened to during ON states on PUSCH and PDSCH, UE enters DRX length weeks Phase.
Each UE is in the setting of SLEEP states or ON states depending on DRX following parameter： OnDurationTimer (duration timer), drx-InactivityTimer, drx-RetransmissionTimer (DRX retransmission timers), longDRX-Cycle (DRX long periods), drxStartOffset (DRX start offsets amount), also may be used The drxShortCycleTimer (DRX short cycle timers) and shortDRX-Cycle (DRX short cycles) of choosing.
In above-mentioned DRX mechanism, used parameter can be configured by RRC and matched somebody with somebody again.Therefore RRC mono- is critically important Decision-making is exactly the good above-mentioned many DRX parameters of configuration, to make UE make balance in terms of power saving and QoS experience.
