Description

A kind of method, system and equipment of DRX timer counting

Technical field

The present invention relates to wireless communication technology field, particularly a kind of method, system and equipment of DRX timer counting.

Background technology

LTE-A(Long Term Evolution-Advanced, long-term evolution upgrading) peak rate of system improves a lot compared with LTE, requires to reach descending 1Gbps, up 500Mbps.Meanwhile, LTE-A system requirements and LTE(Long Term Evolution, Long Term Evolution) system has good compatibility.Based on improve peak rate, with LTE system compatible and the needs that make full use of frequency spectrum resource, LTE-A system has been introduced CA(carrier aggregation) technology.

Carrier aggregation technology is that subscriber equipment can be worked on a plurality of communities simultaneously, and it is up that Yi Ge community comprises a pair of UL()/DL(is descending) CC(Component Carrier, member carrier).In the system of carrier aggregation, each member carrier can be continuously, can be also discrete, and the bandwidth between each member carrier can be identical or different, and in order to keep the system compatible with LTE, the maximum bandwidth limit of each member carrier is 20MHz.It is generally acknowledged that at present the community number maximum number that subscriber equipment can polymerization is 5.

The TDD UL/DL configuration mode of LTE R8 is static or semi-static, can not adjust flexibly TDD UL/DL configuration according to service feature, therefore the QoS(Quality of Service that is unfavorable for elevator system resource utilization, the transmission of better assurance business, quality of service).TDD(Time division duplex during R8, time division duplex) configuration is by SIB(System Information Block, system information block) 1 notice is to UE(subscriber equipment), be that eNB notifies Equipment to UE(User, subscriber equipment by TDD configuration (IE:tdd-Config) with the forms of broadcasting by SystemInformationBlockType1).Based on this, LTE R11 eIMTA(Enhancement to LTE TDD for DL-UL Interference Management and Traffic Adaptation, LTE TDD UL/DL interference management and service adaptation strengthen) project introduced dynamic TDD UL/DL configuration change mechanism, and TDD UL/DL configuration change frequency is shortened to some milliseconds by some skies.

In order to save the energy consumption of UE, extend the service time of UE battery, LTE has introduced DRX(Discontinuous Reception, discontinuous reception) mechanism.DRX mechanism is divided into the RRC_CONNECTED state of UE to activate and the two kinds of different states of mourning in silence.When in state of activation, UE needs to monitor continuously and blind Detecting PDCCH(Physical Downlink Control Channel, physical layer descending control channel), UE can report CQI(Channel Quality Indicator simultaneously, channel quality indication)/PMI(Pre-coding Matrix Indicator, pre-coding matrix indication)/RI(Rank Indication, order indication) information such as.When in silent status, UE does not need to monitor PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel) control channel, do not report the information such as CQI/PMI/RI yet, thereby reach the object of subscriber equipment power saving.Two states is divided based on DRX cycle in time, as shown in Figure 2.

In Fig. 2, a DRX cycle consists of " on " state duration and " off " state duration.During " on " state, UE, in state of activation, needs to monitor continuously PDCCH channel; During " off " state, UE has an opportunity in silent status, but whether in silent status the state based on other timer finally determine.

In current techniques, UE only may obtain 1 cover TDD by broadcast and configures, but dynamic at dynamic() UE may obtain 2 cover TDD configurations (a set of configuration is obtained by broadcast, and a set of configuration is obtained by dedicated signaling or broadcast) in TDD.For many cover TDD configurations, also do not have a kind of employing where to overlap the scheme that TDD configures to carry out DRX timer counting.

At present, also do not have a kind of more for carrying out the scheme of DRX timer counting under dynamic TDD scene.

Embodiment of the present invention network equipment is by the information notifying user equipment for DRX timer counting, so that subscriber equipment is according to for the information of DRX timer counting, DRX timer being counted, thereby realize for carrying out DRX timer counting under dynamic TDD scene, improved network performance.

In declarative procedure below, first from the cooperation of network side and user equipment side, implement to describe, finally from the enforcement of network side and user equipment side, describe respectively, but this does not also mean that the two must coordinate enforcement, in fact, when network side and user equipment side, separate while implementing, also solved respectively in network side, the existing problem of user equipment side, when just the two is combined with, can obtain better technique effect.

As shown in Figure 3, the system of embodiment of the present invention DRX timer counting comprises: network equipment 10 and subscriber equipment 20.

Network equipment 10, for according to TDD configuration change situation, determines and needs notice to the information for DRX timer counting of subscriber equipment; By the information notifying user equipment for DRX timer counting;

Subscriber equipment 20, for receiving the information for DRX timer counting from network equipment; According to determining PDCCH subframe for the information of DRX timer counting, and according to definite PDCCH subframe, DRX timer is counted.

Wherein, network equipment 10 is determined needs notice to have much to the mode of the information for DRX timer counting of subscriber equipment, is introduced respectively below.

Mode one, network equipment are using the TDD configuration information of needs change as the information for DRX timer counting; By the beep-page message that comprises non-TDD configuration change indication information, the SIB(System Information Block of TDD configuration information that comprises needs changes, system information block) 1 and MBSFN(Multimedia Broadcast multicast service Single Frequency Network, multimedia broadcast multi-broadcasting business Single Frequency Network) positional information of subframe is by broadcasting to subscriber equipment;

The beep-page message that subscriber equipment comprises non-TDD configuration change indication information by broadcast reception, the SIB1 of TDD configuration information and the positional information of MBSFN subframe that comprise needs change; Only according to the TDD configuration information of the needs change in the SIB1 receiving corresponding to the beep-page message that comprises non-TDD configuration change indication information, in other subframes except MBSFN subframe, determine PDCCH-subframe(PDCCH subframe), and according to definite PDCCH subframe, DRX timer is counted.

Wherein, SIB is for comprising actual system information.

The sub-frame configuration of removing outside MBSFN in a consideration TDD of mode configuration is determined PDCCH-subframe, statistics DRX timer length.

Subscriber equipment is known community TDD configuration (Legacy TDD configuration) by SIB1, when this configuration is the initial access network of subscriber equipment, by reading system, is broadcasted and is known.When supporting the follow-up generation in the community TDD UL/DL configuration change of dynamic TDD configuration, or while there is change in perUE community TDD configuration, the TDD configuration information that community home base station or other base stations (as macro base station) need to change by subscriber equipment corresponding to broadcast announcement and the positional information of MBSFN subframe.So-called PerUE community TDD configuration refers to that eNB is a TDD configuration certain UE special configuration, that be different from cell-level TDD configuration, and this UE is used specially for the UL/DL sub-frame configuration of its configuration is carried out work.

While adopting forms of broadcasting notifying user equipment TDD configuration change, can adopt following several advice method:

Broadcast mode 1: by Paging(paging) mode of+SIB1 (SIB1 of the TDD configuration information of the beep-page message that comprises non-TDD configuration change indication information+comprise needs change), notice UE TDD configuration change;

The mode of the TDD configuration of broadcast mode 2:MIB(Master Information Block, Master Information Block) carrying in notice, notice UE TDD change;

Broadcast mode 3: indicate by Paging(TDD configuration change) mode of+SIB1 (similar ETWS(Earthquake and Tsunami Warning System, earthquake and tsunami warning system)), notice UE TDD change;

Broadcast mode 4: indicate by Paging(TDD configuration change) mode of+new SIB (similar ETWS), notice UE TDD change.

Here new SIB is a kind of new SIB, different from existing SIB.Existing SIB can be referring to 3GPP TS 36.331 agreements.

When network equipment adopts dedicated signaling form notice UE TDD configuration change, notice UE's can be a set of cell-level TDD configuration, or can be also other TDD configuration of a set of UE level.

Subscriber equipment knows that by broadcast community legacy TDD configuration (obtains according to R8 mechanism, be broadcast mode 1) and MBSFN subframe position (as MBSFN subframe is treated as blank subframe), and according to the sub-frame configuration of removing outside MBSFN in TDD configuration, determine PDCCH-subframe, counting DRX timer.If while there is change in subsequent dynamic TDD configuration, by broadcast mode 1 mode, notify UE TDD configuration change, UE receives after Paging, by TDD configuration and the MBSFN subframe position of the renewal in BCCH modification period acquisition, determines PDCCH-subframe, counting DRX timer; If follow-up eNB is when dynamic TDD configuration change, by broadcast mode 234 or dedicated signaling mode notify UE TDD configuration change, UE determines PDCCH-subframe according to the sub-frame configuration of removing outside MBSFN in legacy TDD configuration all the time, carries out DRX Timer counting.

Concrete, establish by broadcast UE know community legacy TDD be configured to configure 1 and MBSFN subframe position be subframe 4, UE adds up and take the DRX timer duration that PDCCH subframe is digit according to the descending sub frame of TDD configuration 1 (except subframe 4) and DwPTS subframe.Follow-up, eNB is by broadcast (TDD configuration change mode 2,3,4 as dynamic in broadcast announcement) or dedicated signaling notice UE TDD configuration change, UE receives after the TDD configuration change message of eNB notice, still according to the descending sub frame of configuration 1 (except subframe 4) and DwPTS subframe, determine PDCCH subframe pattern, counting DRX timer.

That is to say, subscriber equipment is only determined PDCCH subframe PDCCH-subframe according to the TDD configuration information of the needs change in the SIB1 receiving corresponding with the beep-page message that comprises non-TDD configuration change indication information in other subframes except MBSFN subframe, and according to definite PDCCH subframe, DRX timer is counted.

Preferably, consider TDD UL/DL configuration change time delay, if dynamic TDD configuration change adopts broadcast mode 1 notifying user equipment, subscriber equipment receives that by broadcast mode the TDD of renewal configures at subframe n, subscriber equipment, by the TDD configuration statistics PDCCH-subframe that uses legacy TDD config update mode to notify at subframe n+k, carries out timer counting and PDCCH and monitors.During subframe n arrives subframe n+k-1, original TDD configuration or (common according to configuring with reference to TDD will be used in subscriber equipment and base station, no matter how TDD UL/DL configuration in community changes, DL reference configuration is UL/DL configuration 5, with reference to TDD configuration can be by base station by broadcast announcement to UE, also can be to make an appointment between UE and base station), statistics PDCCH-subframe, carries out DRX timer counting and PDCCH subframe and monitors.Wherein the value of k can be between UE and base station, make an appointment or in agreement, provide default value, can be also base station pass through broadcast or explicit signaling mode notify; Concrete value can be relative value, can be also absolute value (if certain subframe of fixing of network side notice is the TDD UL/DL configuration change moment).

Be that subscriber equipment is according to determining and need to change after TDD configuration for the information of DRX timer counting, at subframe n, in subframe n+k-1, according to the TDD configuration before change or specific T DD configuration, determine PDCCH subframe, and according to definite PDCCH subframe, DRX timer is counted, after subframe n+k, according to Legacy TDD configuration (or the legacy TDD upgrading configuration) or specific T DD configuration, determine PDCCH subframe, and according to definite PDCCH subframe, DRX timer is counted; Network equipment is after subscriber equipment configures according to the informational needs change TDD for DRX timer counting, at subframe n, in subframe n+k-1, according to the TDD configuration before change or specific T DD configuration, process, after subframe n+k, according to Legacy TDD configuration (or the legacy TDD upgrading configuration) or specific T DD configuration, process;

Wherein, subframe n is the subframe of carrying for the information of DRX timer counting, and k is positive integer.

Specific T DD is configured at present existing a kind of TDD configuration (specifically can referring to 3GPP TS 36.211) or new TDD configuration.Concrete which kind of TDD configuration configures and can in agreement, stipulate as specific T DD; Also can be configured by high level; All right network side and user equipment side consult to determine.

Under CA scene, if TDD UL/DL configuration change occurs in the Serving cell of UE polymerization, according to above-mentioned similar fashion, determine PDCCH-subframe.

Mode two, network equipment be using the TDD configuration information of needs change as the information for DRX timer counting, by the beep-page message that comprises non-TDD configuration change indication information, comprise for the SIB1 of the information of DRX timer counting and for the positional information of the specific sub-frame of downlink transmission by broadcasting to subscriber equipment;

Accordingly, subscriber equipment is only determined PDCCH subframe according to the TDD configuration information of the needs change in SIB1 corresponding to the beep-page message that comprises non-TDD configuration change indication information with the positional information of the specific sub-frame for downlink transmission of receiving, and according to definite PDCCH subframe, DRX timer is counted.

Two of modes are considered in TDD configuration the location positioning PDCCH-subframe for the subframe of downlink transmission, statistics DRX timer length.

Subscriber equipment is known community TDD configuration (Legacy TDD configuration) by SIB1, when this configuration is the initial access network of subscriber equipment, by reading system, is broadcasted and is known.When supporting the follow-up generation in the community TDD UL/DL configuration change of dynamic TDD configuration, or while there is change in perUE community TDD configuration, the TDD configuration information that community home base station or other base stations (as macro base station) need to change by subscriber equipment corresponding to broadcast announcement and for the positional information of the specific sub-frame of downlink transmission.The community TDD configuration of so-called PerUE refers to that eNB is a TDD configuration certain UE special configuration, that be different from cell-level TDD configuration, and this UE is used specially for the UL/DL sub-frame configuration of its configuration is carried out work.

Broadcast mode 1: the mode by Paging+SIB1 (SIB1 of the TDD configuration information of the beep-page message that comprises non-TDD configuration change indication information+comprise needs change), notice UE TDD configuration change;

The mode of the TDD configuration of carrying in broadcast mode 2:MIB notice, notice UE TDD change;

Broadcast mode 3: by the mode (similar ETWS) of Paging (indication of TDD configuration change)+SIB1, notice UE TDD change;

Subscriber equipment knows that by broadcast community legacy TDD configuration (obtains according to R8 mechanism, be broadcast mode 1) and for the position, position of the subframe of downlink transmission, and according in TDD configuration for the location positioning PDCCH-subframe of the subframe of downlink transmission, counting DRX timer.If while there is change in subsequent dynamic TDD configuration, by broadcast mode 1 mode, notify UE TDD configuration change, UE receives after Paging, TDD configuration by the renewal that obtains at BCCH modifcation period and for the position location positioning PDCCH-subframe of the subframe of downlink transmission, counting DRX timer; If follow-up eNB is when dynamic TDD configuration change, by broadcast mode 234 or dedicated signaling mode notify UE TDD configuration change, UE all the time according in legacy TDD configuration for the location positioning PDCCH-subframe of the subframe of downlink transmission, carry out DRX Timer counting.

When UE is known legacy TDD configuration by broadcast (obtaining according to R8 mechanism), while knowing the specific Subframe for DL transmission of eNB indication (the specific Subframe for DL transmission, eNB can adopt following form notice: for the Subframe set of DL transmission; simultaneously Be not used in the Subframe set of DL transmission (if which subframe is flexible subframe, so-called flexible subframe sees that by TDD configuration sub-frame configuration is down direction, but be not used in the subframe of descending scheduling/transmission)), UE will configure (according to R8 mechanism, obtaining) and the specific Subframe for DL transmission according to the legacy TDD of knowing all the time, determine PDCCH-subframe, carry out DRX Timer counting.

That is to say, subscriber equipment is only determined PDCCH subframe PDCCH-subframe according to the TDD configuration information of the needs change in SIB1 corresponding to the beep-page message that comprises non-TDD configuration change indication information with the positional information of the specific sub-frame for downlink transmission of receiving, and according to definite PDCCH subframe, DRX timer is counted.

Mode three, network equipment send to subscriber equipment by the TDD configuration information of needs change by broadcast or dedicated signaling as the information for DRX timer counting using the TDD configuration information of needs change;

Accordingly, subscriber equipment is determined PDCCH subframe according to the TDD configuration information of the needs change of receiving, and according to definite PDCCH subframe, DRX timer is counted.

In mode three, according to dynamic TDD, PDCCH-subframe is determined in configuration, statistics DRX timer length; Dynamic TDD configuration is notified to subscriber equipment by broadcast mode.

UE is known community TDD configuration (legacy TDD configuration) by SIB1, when this configuration is the initial access network of UE, by reading system, is broadcasted and is known.When supporting the follow-up generation in the community TDD UL/DL configuration change of dynamic TDD configuration, community home base station or other base stations (as macro base station) notify by broadcast mode the TDD configuration information that corresponding UE is new.UE receives after the TDD configuration that eNB upgrades by broadcast mode, according to the TDD configuration of newly knowing due to dynamic TDD, determine which subframe is PDCCH-subframe, and take the time span of the DRX timer that PDCCH subframe is digit according to definite PDCCH-subframe statistics, monitor PDCCH subframe, carry out DRX timer counting.

That is to say, network equipment sends to subscriber equipment by the beep-page message that comprises non-TDD configuration change indication information with the SIB1 of the TDD configuration information that comprises needs change, correspondingly, subscriber equipment is determined PDCCH subframe according to the TDD configuration information of the needs change in SIB1 corresponding to the beep-page message that comprises non-TDD configuration change indication information, and according to definite PDCCH subframe, DRX timer is counted; Or

Network equipment sends to subscriber equipment by the MIB of the TDD configuration information that comprises needs change, correspondingly, subscriber equipment is determined PDCCH subframe according to the TDD configuration information of the needs change in the MIB receiving, and according to definite PDCCH subframe, DRX timer is counted; Or

Network equipment sends to subscriber equipment by the beep-page message that comprises TDD configuration change indication information with the SIB1 of the TDD configuration information that comprises needs change, correspondingly, subscriber equipment is determined PDCCH subframe according to the TDD configuration information of the needs change in SIB1 corresponding to the beep-page message that comprises TDD configuration change indication information, and according to definite PDCCH subframe, DRX timer is counted; Or

Network equipment sends to subscriber equipment by the beep-page message that comprises TDD configuration change indication information with the specific SIB of the TDD configuration information that comprises needs change, correspondingly, subscriber equipment is determined PDCCH subframe according to the TDD configuration information of the needs change in specific SIB corresponding to the beep-page message that comprises TDD configuration change indication information, and according to definite PDCCH subframe, DRX timer is counted.

When network equipment adopts dedicated signaling form notice UE TDD configuration change, notice UE's can be a set of cell-level TDD configuration, or can be also other TDD configuration of a set of UE level.UE is known after the TDD configuration of notifying by dedicated signaling, according to the TDD configuration of dedicated signaling notice, determines PDCCH-subframe, carries out DRX Timer counting.

Concrete, while establishing the initial access network of UE, by broadcast, know that community legacy TDD is configured to configure 0, UE and according to TDD, configures 0 descending sub frame and DwPTS sub-frame count and take the DRX timer that PDCCH subframe is digit.Follow-up, if network equipment by broadcast mode 234 or dedicated signaling mode notify UE TDD configuration change (if TDD configuration change is configuration 1), UE receives after the TDD configuration change message of network equipment notice, according to the TDD configuration of the renewal of knowing (TDD configuration 1) statistics PDCCH-subframe, according to descending sub frame and the DwPTS sub-frame count DRX timer of TDD configuration 1; If it is 1 that eNB notifies UE TDD configuration change by broadcast mode 1 mode, UE receives after Paging, by the TDD configuration 1 of the renewal in BCCH modification period acquisition, according to descending sub frame and the DwPTS sub-frame count DRX timer of TDD configuration 1.

Preferably, consider TDD UL/DL configuration change time delay, if dynamic TDD configuration broadcast mode 1 notifying user equipment, subscriber equipment receives that by broadcast mode 1 TDD of renewal configures at subframe n, subscriber equipment, by the TDD configuration statistics PDCCH-subframe that uses legacy TDD update mode to upgrade at subframe n+k, carries out timer counting and PDCCH and monitors.During subframe n arrives subframe n+k-1, original TDD configuration or (common according to configuring with reference to TDD will be used in subscriber equipment and base station, no matter how TDD UL/DL configuration in community changes, DL reference configuration is UL/DL configuration 5, with reference to TDD configuration can be by base station by broadcast announcement to UE, also can be to make an appointment between UE and base station), statistics PDCCH-subframe, carries out DRX timer counting and PDCCH subframe and monitors; If dynamic TDD configuration change adopt broadcast mode 234 or dedicated signaling mode notifying user equipment, subscriber equipment subframe n by broadcast mode 234 or dedicated signaling mode receive that the TDD of renewal configures, subscriber equipment, by use the TDD configuration statistics PDCCH-subframe upgrading at subframe n+k, carries out timer counting and PDCCH and monitors.During subframe n arrives subframe n+k-1, subscriber equipment and base station will be used original TDD configuration or according to reference to TDD configuration, be added up PDCCH-subframe, carry out DRX timer counting and the monitoring of PDCCH subframe.。Wherein the value of k can be between UE and base station, make an appointment or in agreement, provide default value, can be also base station pass through broadcast or explicit signaling mode notify; Concrete value can be relative value, can be also absolute value (if certain subframe of fixing of network side notice is the TDD UL/DL configuration change moment).

Be that subscriber equipment is according to determining and need to change after TDD configuration for the information of DRX timer counting, at subframe n, in subframe n+k-1, according to the TDD configuration before change or specific T DD configuration, determine PDCCH subframe, and according to definite PDCCH subframe, DRX timer is counted, after subframe n+k, according to the TDD configuration after change or specific T DD configuration, determine PDCCH subframe, and according to definite PDCCH subframe, DRX timer is counted; Network equipment is after subscriber equipment configures according to the informational needs change TDD for DRX timer counting, at subframe n, in subframe n+k-1, according to the TDD configuration before change or specific T DD configuration, process, after subframe n+k, according to the TDD configuration after change or specific T DD configuration, process;

Mode four, mode four is similar with mode three, and difference is only that network equipment also sends to subscriber equipment by the positional information of MBSFN subframe or for the positional information of the specific sub-frame of downlink transmission; Accordingly, if subscriber equipment receives the positional information of MBSFN subframe, the TDD configuration information that subscriber equipment changes is as required determined PDCCH subframe in other subframes except MBSFN subframe, and according to definite PDCCH subframe, DRX timer is counted;

If subscriber equipment receives the positional information for the specific sub-frame of downlink transmission, the TDD configuration information that subscriber equipment changes as required and determine PDCCH subframe for the positional information of the specific sub-frame of downlink transmission, and according to definite PDCCH subframe, DRX timer is counted.

Mode five, network equipment, using the positional information of the specific sub-frame for downlink transmission as the information for DRX timer counting, are notified the positional information of the specific sub-frame for downlink transmission to subscriber equipment by broadcast or dedicated signaling;

Accordingly, subscriber equipment is determined PDCCH subframe according to the positional information of the specific sub-frame for downlink transmission, and according to definite PDCCH subframe, DRX timer is counted.

In mode five, subscriber equipment is counted (if the words that have that new flexible subframe type configuration to occur according to the specific subframe for downlink transmission in broadcast or dedicated signaling, this subframe is not used in PDCCH subframe counting), statistics DRX timer length.

Network equipment is notified to the mode of subscriber equipment and the advice method of mode three similar by broadcast or dedicated signaling, do not repeat them here.

The positional information that is used for the specific sub-frame of downlink transmission includes but not limited to a kind of of following message:

TDD configuration and the Subframe set of transmitting for DL;

TDD configuration and the Subframe set (if which subframe is flexible subframe) that is wherein not used in DL transmission;

Subframe set for DL transmission;

Be not used in the Subframe set (if which subframe is flexible subframe) of DL transmission;

Notify the current subframe for DL transmission.

For example, if network equipment is configured to configure 1 by broadcast announcement UE community TDD, UE take according to the descending sub frame of TDD configuration 1 and DwPTS subframe statistics the DRX timer duration that PDCCH-subframe is digit.If subsequent base stations be flexible subframe by broadcast or dedicated signaling notice UE subframe 9, UE adds up and take the DRX timer duration that PDCCH subframe is digit according to the descending sub frame of TDD configuration 1 (except subframe 9) and DwPTS subframe.
