Optionally, base station sends the configuration information of described group of common downlink control channel by the way of the prior art.

Optionally, after base station sends the configuration information of described group of common downlink control channel, one is sent to the UE of the group Group common downlink controls information, that is to say, that organize as granularity each UE into group, to send the corresponding group of the group public for base station Downlink Control Information,

It is understood that sending each corresponding group of common downlink control of UE to each UE using single UE as granularity with the prior art Information processed is different, in this step, for one group of UE, only sends a group common downlink and controls information, can save group it is public under The row control occupied resource of information.

For example, a certain group includes 2 UE, then base station only needs to send a group common downlink control to 2 UE of the group Information processed.In compared to the prior art, a group common downlink is sent for 1 UE and controls information, then needs to distinguish for 2 UE Two group common downlink control information are sent, using the embodiment of the present invention, 1 transmission group common downlink control information can be saved Resource.

Optionally, UE monitoring group common downlink control channel, according to matching for the group common downlink control channel obtained in advance Confidence breath obtains described group of common downlink control information, and controls information according to described group of common downlink, when obtaining the transmission Between be spaced, described group of common downlink control information is used to indicate Transmission Time Interval, and UE is received according to the Transmission Time Interval The downlink data of base station, or upstream data is sent to base station.

Optionally, the Transmission Time Interval is determined by base station according to state of the current network, and the mode of the prior art can be used It determines.

Optionally, described group of common downlink control information is base station to organize as scheduling granularity, is sent to one group of UE, institute Stating UE can get described group of common downlink control information, and the group that UE of cell other groups can not obtain the transmission of this base station is public Downlink Control Information.

It is understood that since this group of UE obtains the configuration information of described group of common downlink control channel in advance, the group After UE detects described group of common downlink control information, according to the configuration information of described group of common downlink control channel, it can parse Obtain the content of described group of common downlink control information, the configuration information without obtaining described group of common downlink control channel UE can not detect described group of common downlink control information, or detect described group of common downlink control information, can not parse The content of described group of common downlink control information is obtained, thereby guarantees that each group of UE can get group common downlink corresponding to the group Control information.

The method of transmission process provided in this embodiment, at least has following technical effect that

Information is controlled by sending a group common downlink to multiple UE, so that the UE is public according to the group obtained in advance The configuration information of down control channel obtains described group of common downlink control information, and according to described group of common downlink control letter Breath, obtains the Transmission Time Interval, thus can save the transmission group common downlink control occupied resource of information.

On the basis of the above embodiments, the method for transmission process provided in an embodiment of the present invention, which comprises

A group common downlink is sent to multiple UE by group common downlink control channel and controls information, and the UE belongs to together One group, described group is grouped to the UE of cell access, described group of common downlink according to preset transmission strategy Control information is used to indicate the Transmission Time Interval of this group of UE, so that the UE is according to the group common downlink control letter obtained in advance The configuration information in road, obtains described group of common downlink control information, and controls information according to described group of common downlink, described in acquisition Transmission Time Interval.

There are many modes being grouped in the method, and the present embodiment is illustrated for one of kind.

Described group is to be grouped according to preset transmission strategy to the UE of cell access, specifically:

Described group is to be grouped according to the service feature require information of the UE of cell access to UE.

Optionally, the service feature require information of UE indicates requirement of the business of UE application to performance.

Optionally, the business of UE application has certain requirement to delay performance, and the requirement to time delay this performance is consistent UE point be one group, i.e., demanding to time delay to be divided into one group, i.e., of less demanding to time delay is divided into one group.

For example, the corresponding time delay budget of UE is that 100ms is believed that the business of application to delay requirement height, time delay budget Business greater than 100ms application is of less demanding to time delay.

It correspondingly, is one group to demanding UE points of time delay by the business of UE application, by the business of UE application to time delay UE of less demanding point be another group.

It is understood that carrying out the grouping of UE according to the service feature require information of UE, UE can be more reasonably obtained Group.

Optionally, the service feature require information of UE can be following at least one of them: type of service, bearer types and QoS (Quality of Service, service quality) grade.

Optionally, base station is grouped UE according to the above at least one of them, and obtains corresponding group common downlink control The configuration information of channel processed.

Optionally, type of service is the type of service of UE application.For example, can for call, game, data, voice, The types such as VOLTE, webpage, video, file transmission, the highly reliable business of low time delay, super large data volume broadband services.

It is understood that above-mentioned type of service is only for example, it is not limited, it can be according to the industry of network in practical application Service type is adjusted.

Optionally, base station receive UE transmission for request registration/use business message, the message includes service class Type, base station are handled according to the state of type of service and UE, and record the type of service of UE, according to the type of service of UE, are given UE grouping.

Optionally, if the service feature require information of UE is type of service, UE is divided according to type of service in base station There are many modes of group, is illustrated for two kinds below.

If the service feature require information of UE is type of service, identical UE points of type of service is one group by base station, or UE points identical to performance requirement of type of service is one group by person.

Optionally, for the UE of a cell, the type of service of UE is obtained, and be divided into one group for type of service is identical, It is that call is divided into one group by type of service, type of service is divided into one group for webpage, and so on.

Optionally, the type of service of UE is obtained, and be divided into one group for type of service is identical to performance requirement.

Optionally, different types of service may be the same or different performance requirement.

For example, performance can be time delay, and type of service is consistent to delay requirement to be divided into one group, i.e., to delay requirement height Be divided into one group, i.e., of less demanding to time delay is divided into one group.

For example, time delay budget is that 100ms is believed that the business of application is high to delay requirement, and time delay budget is greater than The business of 100ms application is of less demanding to time delay.

Correspondingly, be call by type of service, type of service is game and type of service is the highly reliable business of low time delay UE point be first group, be that data, voice, VOLTE, webpage, video, file transmission and super large data volume are wide by type of service UE with business points are second group, it is to be understood that first group of type of service is the business more demanding to time delay, the Two groups of type of service is the business of less demanding to time delay.

Optionally, if the service feature require information of UE is bearer types, for example, the bearer types of UE can be RB (radio bearer, the radio bearer between UE and eNB), S1 carry (carrying between eNB and S-GW), S5/S8 carries (S-GW Carrying between P-GW), default bearing (default bearer), the types such as dedicated bearer (dedicated bearer), In, RB is divided into SRB (Signaling Radio Bearer, Signaling Radio Bearer) and DRB (Data according to the different of content again Radio Bearer, Data Radio Bearer), further, SRB is divided into SRB0, SRB1 and SRB2 according to the different of message again.

It is understood that above-mentioned bearer types are only for example, it is not limited, can be held according to network in practical application Type is carried to be adjusted.

Optionally, base station receives the message for requesting foundation to carry of UE transmission, and the message includes bearer types, base It stands and is handled according to the state of bearer types and UE, and record the bearer types of UE, according to the bearer types of UE, to UE points Group.

Optionally, there are many modes that base station is grouped, and is illustrated by taking one kind as an example below.

If the service feature require information of UE is bearer types, identical UE points of bearer types is one group by base station, or UE points identical to performance requirement of bearer types is one group by person.

Optionally, the bearer types of UE are obtained for the UE of a cell, and be divided into one group for bearer types are identical, Bearer types are divided into one group for RB, bearer types are divided into one group for S1, and so on.

Optionally, for radio bearer RB, SRB and DRB are divided into according to the difference of carrying content, and come to performance requirement It sees, performance requirement can be customer service demand and Qos grade, can be divided into GBR according to customer service demand and Qos grade difference (Guaranteed Bit Rate guarantees bit rate) and Non-GBR carrying.

Optionally, QoS grade is to characterize the priority of service quality, and different business, different is held different users It carries, different QoS is provided.

For example, the QoS grade of UE can be there are many grade according to standard difference.

Optionally, by taking 3GPP23.401 as an example, QoS grade is 1-9 totally 9 seed type.

It is understood that above-mentioned QoS grade is only for example, it is not limited, it can be according to the QoS of network in practical application Grade is adjusted.

Wherein GBR class carries, for needing scheduler to guarantee such carrying minimum to the higher business of requirement of real-time Bit rate, the range of QCI (QoS Class Identifier, service quality scale value) is 1-4.

Optionally, GBR is the carrying for guaranteeing bit rate, using priority scheduling, when postpone a meeting or conference it is relatively low.

On the contrary, Non-GBR class carries, for the business not high to requirement of real-time, scheduler is not needed to such carrying Guarantee minimum bit rate, the range of QCI is 5-9, therefore Non-GBR does not have to ensures bit rate, dispatching priority rearward, Time delay is with regard to relatively large.

So the grouping to UE can be carried out according to the performance requirement of customer service demand and Qos grade.

Optionally, if the service feature require information of UE is QoS grade, base station receives establishing for request for UE transmission The message of carrying, the message include bearer types and QoS grade, base station according to the states of bearer types, QoS grade and UE into Row processing, and the QoS grade of UE is recorded, according to the QoS grade of UE, it is grouped to UE.

Optionally, there are many modes that base station is grouped according to QoS grade, is illustrated for two kinds below.

Optionally, for the UE of a cell, base station is identical by QoS grade or QoS grade is identical to performance requirement UE points are one group.

Optionally, the QoS grade of UE is obtained, and be divided into one group for QoS grade is identical, i.e., point for being 1 by QoS grade It is one group, is 2 to be divided into one group by QoS grade, and so on.

Optionally, the QoS grade of UE is obtained, and be divided into one group for QoS grade is identical to performance requirement.

Optionally, different QoS grades may be the same or different performance requirement.

For example, performance can be time delay, and QoS grade is consistent to delay requirement to be divided into one group, i.e., to delay requirement height Be divided into one group, i.e., of less demanding to time delay is divided into one group.

For example, time delay budget is that 100ms is believed that the corresponding QoS grade of the business of application is high to delay requirement, when It is of less demanding to time delay to prolong the budget QoS grade corresponding greater than the business of 100ms application.

It correspondingly, is 1 and 2 to be divided into first group by QoS grade, QoS grade is 8 and 9 to be divided into second group, it is possible to understand that , first group is the business more demanding to time delay, and second group is the business of less demanding to time delay.

Other steps of the present embodiment are similar to the aforementioned embodiment, and this embodiment is not repeated.

UE is grouped according to type of service, bearer types and/or QoS grade, can more rationally obtain UE grouping.

On the basis of the above embodiments, the method for the transmission process that further embodiment of this invention provides, the method packet It includes:

There are many modes that the Transmission Time Interval is determined in the method, and the present embodiment is said by taking one kind as an example It is bright.

Optionally, base station according to it is following at least one, determine described group of common downlink control information:

The Transmission Time Interval is determined according to the service feature require information of the UE.

Optionally, the business of UE application has certain requirement to delay performance.The business clock synchronization applied according to one group of UE The requirement for prolonging this performance determines the Transmission Time Interval.In a group.The business of UE application to there are many delay requirements, 50ms may be selected as the Transmission Time Interval in such as 50ms, 100ms, and 100ms also may be selected as between the transmission time Every the adjustment of Transmission Time Interval can be carried out according to the actual situation certainly.

Optionally, the service feature require information of UE can be following at least one of them: type of service, bearer types and QoS grade.

Optionally, the Transmission Time Interval of different groups is different, and the value of the Transmission Time Interval is related to group.

For example, it is grouped according to the delay requirement of type of service, then the Transmission Time Interval organized is related with time delay. For the UE of the high group of delay requirement, the TTI of the group of transmission is smaller, to meet business demand, for the not high group of delay requirement UE, the TTI of the group of transmission is larger.

Optionally, the TTI can be TTI unit, and the Transmission Time Interval is scheduling interval and feedback interval two ginsengs Number.

Optionally, scheduling interval may include down control channel dispatched with it downlink traffic channel interval, downlink control The reverse link traffic channel interval that channel is dispatched with it is with feedback interval may include the corresponding uplink feedback of downlink traffic channel The corresponding downstream feedback control channel interval of control channel interval, reverse link traffic channel.

The Transmission Time Interval is determined according to the service feature require information of the UE of the group, may be implemented targetedly to match The Transmission Time Interval of this group of UE set.

There are many acquisition modes of the configuration information of the described group of common downlink control channel of the method, the present embodiment with It is illustrated for three kinds.

Optionally, the configuration information of described group of common downlink control channel is that UE is obtained according to following one way in which :

Information, RRC dedicated signaling and the system message of pre-configuration.

Optionally, the information being pre-configured is provided in the protocol, and UE obtains described group of common downlink according to the information of pre-configuration The configuration information of control channel.

Optionally, it is notified without base station, after UE completes to be initially accessed, UE is not yet grouped or not yet at this time When receiving the configuration information of group common downlink control channel, UE organizes common downlink control according to the acquisition of information of pre-configuration The configuration information of channel.

Optionally, base station notifies the configuration information of described group of common downlink control channel using RRC dedicated signaling.

Optionally, RRC is UE and the connection that base station is established, and carries the signaling of UE and base station.

Optionally, base station notifies the configuration information of described group of common downlink control channel based on the system message of group.

Optionally, system message, can the period by BCCH (Broadcast Control Channel, broadcast control channel) System information of the property based on each cell is broadcasted.

UE makes UE that can obtain described group of common downlink according to the information of pre-configuration, RRC dedicated signaling and/or system message The configuration information of control channel, and monitored according to the configuration information of described group of common downlink control channel.

If the service feature require information of UE changes in the method, base station should also correspond to adjustment transmission control, adjustment Mode can there are many, the present embodiment is illustrated for two kinds.

If the service feature require information of UE changes, according to the service feature require information of the UE after change, again to UE Grouping.

Optionally, change when the service feature require information of a UE in base station discovery group generates, then adjust the UE's Grouping.

For example, first group of UE is more demanding to a certain service feature, and second group of UE wants a certain service feature It asks not high, when the service feature of first group of some UE, which requires, to be reduced, then the UE is transferred to second group.

Optionally, if the service feature require information of UE changes, according to the service feature require information of the UE after change, weight Newly configure the Transmission Time Interval of this group of UE.

Optionally, if the service feature require information of UE changes, the group of UE can not be changed, base station is according to the UE after change Service feature require information, reconfigure corresponding Transmission Time Interval.

For example, first group of UE is more demanding to a certain service feature, correspondingly, first group of Transmission Time Interval Shorter, second group of UE is of less demanding to a certain service feature, and correspondingly, second group of Transmission Time Interval is longer, when first When the service feature of most of UE in group requires to reduce, then increase by first group of Transmission Time Interval.

If the service feature require information of UE changes, UE is grouped or is reconfigured again the transmission of this group of UE Time interval, so that being changed in real time according to the service feature require information of UE and being changed, to guarantee to carry out in real time, accurately for UE The configuration of Transmission Time Interval.

The method sends a group common downlink to multiple UE by group common downlink control channel and controls information, base station Transmission group common downlink controls there are many modes of information, and the present embodiment is illustrated for two kinds.

Optionally, the Transmission Time Interval of one group of UE is carried in the public DCI of group, controls UE detection group common downlink Channel, the public DCI of acquisition group.

Optionally, the configuration information of described group of common downlink control channel is preset group of common downlink control channel search The range in space, it is correspondingly, described that a group common downlink control letter is sent to multiple UE by group common downlink control channel Breath, specifically:

A group common downlink is sent to multiple UE in group common downlink control channel search space and controls information, for institute UE is stated in the range detection of preset group of common downlink control channel search space, obtains described group of common downlink control information.

Agreement regulation, the search range of the PDCCH blind examination of UE are known as search space, and search space is divided into public search space (Common Search Space, CSS) and UE dedicated search space (UE-specific search space, USS).It is public Search space is that all terminals require detection in cell altogether, and user's dedicated search space is for each terminal.

Optionally, the configuration information of described group of common downlink control channel is corresponding group of public search space of UE, to refer to Show the range of UE search.

Optionally, group public search space is to the different specific group public search spaces of group configuration, correspondingly, base station Information is controlled to the group common downlink of one group of UE transmission group by group public search space, carries out UE in group public search space The group common downlink of search, acquisition group controls information.

It is understood that the embodiment of the present invention proposes the concept of group public search space, with public affairs in the prior art Altogether search space and UE dedicated search space it is different, by be one group of UE configuration group public search space, define only this The range that can search for of UE of group is, it can be achieved that the public space that multiple UE under one group can search for, and compared to the prior art special Resource is saved with search space.

Optionally, the configuration information of described group of common downlink control channel is that preset group of common downlink controls the close of information Code, it is correspondingly, described that a group common downlink control information is sent to multiple UE by group common downlink control channel, specifically Are as follows:

Information is controlled to the group common downlink that multiple UE send an encryption by group common downlink control channel, for institute It states UE the group common downlink control information of the encryption is decrypted according to group password of common downlink control information, obtains institute State a group common downlink control information.

Optionally, the configuration information of described group of common downlink control channel is the corresponding password of UE, so that this group of UE is used The group common downlink control information of encryption is decrypted in password, and the group common downlink of acquisition group controls information.

Optionally, password is that specific password is configured to different groups, and the password of difference group is different.

Correspondingly, base station encrypts group common downlink control information using password, makes UE using password to encryption Group common downlink control information is decrypted, and the group common downlink of acquisition group controls information.

Agreement regulation, PDCCH are used to carry the DCI of one or more UE, i.e. DCI due to using can unique identification UE UE Mark C-RNTI scrambles DCI, is the exclusive DCI of UE.

It is understood that carrying out DCI transmission as password, by granularity of UE with the mark in the prior art for using UE Difference, the embodiment of the present invention define that the UE of the only group can decrypt DCI, it can be achieved that one group by configuring password for one group of UE Under multiple UE can get a group DCI, and the exclusive DCI of UE compared to the prior art saves resource.

Optionally, password is RNTI (Radio Network Tempory Identity, radio network temporary identifier).

Optionally, after scrambling to group common downlink control information using group RNTI, it is sent to one group of UE.

For example, RNTI1 is the password of first group of UE, and RNTI2 is the password of second group of UE.

Optionally, one group of UE cannot achieve the position for knowing group common downlink control information, continue blind examination, to detecting To each group common downlink control information be decoded using the password that receives in advance, when that can be decoded using password, Described group of common downlink control information is that the group common downlink of this group controls information.

Information is controlled to a group common downlink is sent in group common downlink control channel search space, or sends one As long as the group common downlink control information of encryption controls information, it can be achieved that this group of UE can get group common downlink, other UE can not This group of common downlink control information is obtained, realizes and targetedly carries out transmission process.

Sent in the method group common downlink control information mode can there are many, the present embodiment is for two kinds It is illustrated.

A group common downlink, which is sent, to multiple UE by group common downlink control channel controls information, specifically:
