Description

Carrier wave activates processing method, base station and the UE of relevant information
Technical field
The embodiment of the invention relates to communication technical field, relates in particular to processing method, base station and subscriber equipment (User Equipment is called for short UE) that a kind of carrier wave activates relevant information.
Background technology
In the LTE system, base station (Evolved Node B, be called for short eNB) and UE communicates and transfer of data.The data that the UE that is scheduled for transmits in each subframe generally comprise Physical Downlink Control Channel (the Physical Downlink Control Channel of oneself, be called for short PDCCH) signaling, this PDCCH signaling has been carried the time-frequency resource allocating information of indication physical data channel.UE carries out respective handling to PDCCH and also determines the control information of oneself in the search volume, carry out further data processing according to this control information.
In the LTE of evolution system (LTE Advanced is called for short LTE-A), introduced carrier aggregation (Carrier Aggregation) technology, promptly the resource of a plurality of carrier waves can have been dispatched simultaneously to a UE and use, to satisfy higher peak rate and business demand.The base station is by semi-static Radio Resource control (Radio Resource Control, abbreviation RRC) signaling sends configuration information to UE, the carrier set of its required monitoring of notice UE, the carrier wave collection that UE need monitor is called PDCCH monitoring collection (PDCCHmonitoring set), is the subclass of user's downlink member carrier set (User Equipment DownlinkComponent Carrier Set).Article one, control channel is only to dispatch the transfer of data of a carrier wave, in carrier aggregation technology, UE polymerization simultaneously a plurality of carrier data transmission, then need many control channels.
In having adopted the LTE-A system of carrier aggregation technology, UE need dispose the data that one or more radio-frequency modules are handled a plurality of carrier waves, if a plurality of carrier waves all are in state of activation, one or more radio-frequency modules of UE need to open so, cause the UE power consumption very serious.In order to reduce the power consumption of UE, in some cases, can make the carrier wave corresponding radio frequency module of UE deexcitation close some carrier wave deexcitation.For example, under the less situation of the current traffic carrying capacity of UE, the base station can be with some carrier wave deexcitation of UE, and the carrier wave of deexcitation is notified to UE, UE can close by the carrier wave corresponding radio frequency module of deexcitation (if all carrier waves among the UE are handled by a radio-frequency module, then can not close this radio-frequency module).Under the bigger situation of UE traffic carrying capacity, the base station can be activated the carrier wave of deexcitation again, and the carrier wave that activates again is notified to UE, and UE can open the carrier wave corresponding radio frequency module that is activated again.
In the prior art, the base station is to notify the UE carrier wave to activate or the information of deexcitation by send signaling to UE, and particularly, at the newly-increased bit of signaling, this newly-increased bit can represent that carrier wave activates or deexcitation information; Perhaps use newly-increased scrambler to existing signaling scrambling, i.e. signaling after the scrambler scrambling that use increases newly is carried carrier wave and is activated or deexcitation information.
The problem that this carrier wave of the prior art activates or deexcitation information processing method exists is: added bits can be brought extra expense, and after the added bits, causes the length of signaling elongated, makes the form of signaling become complicated, is unfavorable for blind Detecting.Use newly-increased scrambler then can reduce existing scrambler space, simultaneously false alarm probability is had adverse effect.

Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Be illustrated in figure 1 as the flow chart that carrier wave of the present invention activates an embodiment of processing method of relevant information, comprise:
Step 101, network side obtain carrier wave and activate relevant information.This carrier wave activate that relevant information comprises that carrier wave activates and deexcitation information at least one.
In the step 101, specifically can be that base station by network side obtains carrier wave and activates relevant information.The different moment, the traffic carrying capacity difference of certain UE, the base station can judge needs activate which carrier wave of UE according to the current traffic carrying capacity of UE, with which carrier wave deexcitation of UE, that is to say that the base station can obtain carrier wave according to the current business amount of UE and activate relevant information.
Step 102, network side send the PDCCH signaling to UE, these two the incompatible expression carrier wave of acquiescence redundancy group of acquiescence redundant bit in this PDCCH signaling, acquiescence redundant state or scrambler and state activates relevant information, handles accordingly so that UE activates relevant information according to the carrier wave of PDCCH denoting signaling.This step 102 specifically can be carried out by the base station of network side.
The PDCCH signaling is meant the signaling of transmitting in the PDCCH channel.According to present regulation, comprise these two the redundant combination of acquiescence of some acquiescence redundant bits, acquiescence redundant state or scrambler and state in some PDCCH signaling.
The acquiescence redundant bit is meant not to be stipulated at present concrete implication, current system disables or is used for giving over to the bit of follow-up use.
The acquiescence redundant state is meant not to be stipulated at present concrete implication, current system disables or is used for giving over to some particular states of follow-up use.For example, a field A in certain PDCCH signaling comprises two bits, can comprise 4 kinds of states behind these two bit padding datas so: 00,01,10,11.May stipulate the implication of state 00 and 11 expressions at present, still not have the implication of specified states 01 and 10, state 01 and 10 is exactly the redundant state of acquiescence so, and 01 or 10 can identify as carrier wave activation or deexcitation.
These two the redundant combination of acquiescence of scrambler and state is meant does not stipulate concrete implication, current system disables at present or is used for giving over to these two the combination of the scrambler of follow-up use and state.For example, certain PDCCH signaling can be used scrambler C scrambling, certain field A in this PDCCH signaling can comprise a state S and other states, using scrambler C scrambling and field A is this combination of state S, do not stipulate at present that concrete implication, this combination are exactly a kind of redundant combination of giving tacit consent to.
UE is after receiving the PDCCH signaling, if detect these two the redundant combination of acquiescence of this class acquiescence redundant bit, acquiescence redundant state or scrambler in the PDCCH signaling and state, then can determine to carry in this PDCCH signaling carrier wave and activate relevant information, thereby can determine that the carrier wave in the PDCCH signaling activates the content that relevant information is represented.
According to present regulation, the PDCCH signaling is used to transmit the downlink or uplink schedule information.Activate relevant information if carry carrier wave in the PDCCH signaling, the PDCCH signaling just is different from the PDCCH signaling of present regulation so, carry carrier wave and activated other each bit or field in the PDCCH signaling of relevant information, can give new implication by reinterpreting according to the demand of system.
The carrier wave that the embodiment of the invention provides activates the processing method of relevant information, these two the incompatible expression carrier wave of acquiescence redundancy group of acquiescence redundant bit in the PDCCH signaling, acquiescence redundant state or scrambler and state activates relevant information, need on the basis of existing P DCCH signaling, not increase bit, do not need to use newly-increased scrambler to the scrambling of existing P DCCH signaling yet, but utilized existing P DCCH signaling fully, can not cause extra expense, can not reduce the scrambler space of existing P DCCH signaling; And the carrier wave that the embodiment of the invention provides activates the processing method of relevant information, need not to change the length or the structure of existing PDCCH signaling, makes troubles can for the blind Detecting of PDCCH.
Be illustrated in figure 2 as the flow chart that carrier wave of the present invention activates another embodiment of processing method of relevant information, comprise:
Step 201, UE receive the PDCCH signaling that network side sends.
Step 202, UE resolve the PDCCH signaling.
If comprise in the step 203 PDCCH signaling by these two the carrier wave of the redundant combination expression of acquiescence of acquiescence redundant bit, acquiescence redundant state or scrambler and state and activate relevant information, then, set pattern determines that then carrier wave activates the content that relevant information is represented according to being set really.
This obtains really set pattern in advance and then can be stored in advance among the UE, and which information is which field in can regulation PDCCH signaling in this definite rule carry, and how determines that according to the information of each field carrier wave activates the content that relevant information represents etc.
Carrier wave corresponding radio frequency module that step 204, UE open and need activate and/or the carrier wave corresponding radio frequency module of closing and need deexcitation.
If do not comprise in the PDCCH signaling by these two the carrier wave of the redundant combination expression of acquiescence of acquiescence redundant bit, acquiescence redundant state or scrambler and state and activate relevant information,, determine the control information in the PDCCH signaling according to the regulation in the existing protocol.
The carrier wave that the embodiment of the invention provides activates or anti-activating method, UE is after receiving the PDCCH signaling, comprise in the PDCCH signaling that these two the carrier wave of the redundant combination expression of acquiescence of acquiescence redundant bit, acquiescence redundant state or scrambler and state activates relevant information, compared with prior art, can not cause extra expense.And,, make troubles can for the blind Detecting of the PDCCH of UE because the length of the PDCCH signaling that receives or structure do not change.
The PDCCH signaling comprises a variety of, and these two the redundant combination of acquiescence of the acquiescence redundant bit in the various PDCCH signalings, acquiescence redundant state or scrambler and state also has nothing in common with each other.
In the system that has used carrier aggregation technology, for example (being the example introduction mainly in following examples) in the LTE-A system with the LTE-A system, carrier wave activates or the granularity of deexcitation can vary.Roughly can comprise following two classes:
I, the whole activation or the deexcitation granularity
Under this activation or deexcitation granularity, for situation about activating, be once will be except when preceding n-1 the carrier wave that is in outside the state of activation carrier wave that is used for the bearing activation signaling all activates, n is the carrier number in the set of user's downlink member carrier; For the situation of deexcitation, owing to n the whole deexcitations of carrier wave can not be activated and must keep a carrier wave, so in this case, be with n-1 the whole deexcitations of carrier wave, keep a carrier wave and activate.
II, the local activation or the deexcitation granularity
This activation or deexcitation granularity are that single carrier wave or quantity are less than or equal to the carrier wave set that the carrier wave of n-1 is formed, and once can activate or the single carrier wave of deexcitation, perhaps once can activate or deexcitation quantity or equal carrier wave less than n-1.
Carrier wave activates relevant information and is meant which carrier wave need be activated, need be with the information of which carrier wave deexcitation.For I kind granularity, need not in the PDCCH signaling to comprise concrete needs activate or deexcitation be which carrier wave because need to activate or the number of carriers of deexcitation fixedly is n-1.
For II kind granularity, can comprise in the PDCCH signaling that carrier wave activates and/or the deexcitation content, which carrier wave need be activated to illustrate specifically, need with which carrier wave deexcitation.
For II kind granularity, in the PDCCH signaling, be used for representing that the bit number of carrier wave activation and/or deexcitation content can equal the carrier number of LTE-A system, can equal system configuration and give the set carrier number that does not rely on the set of user's downlink member carrier of UE, also can equal the carrier number in the set of user's downlink member carrier.
For example, suppose that the LTE-A system always has 5 carrier waves, and the carrier number in a certain moment user downlink member carrier set is wherein 3, in the PDCCH signaling, is used for representing that the bit number of carrier wave activation and/or deexcitation content equals the carrier number 5 of LTE-A system so.
Like this, when base station transmission RRC reshuffles the set of signaling change user downlink member carrier, can not receive RRC and reshuffle signaling because of UE, perhaps UE receives that RRC reshuffles signaling and the base station is not also received to reshuffle and finished signaling, causes UE to resolve mistakenly that carrier wave that the base station sends activates or the PDCCH signaling of deexcitation.
In the prior art, the base station sends RRC and reshuffles signaling and send to UE and change the set of user's downlink member carrier, UE is receiving that correctly RRC reshuffles signaling and will operate accordingly according to the information in the signaling, but the base station only could have been determined after reshuffling of receiving that UE sends finished signaling the configuration successful of UE.That is to say that in the blanking time of two signalings, the base station can't determine whether UE has correctly received RRC and reshuffled signaling.So, if reshuffling under the situation of finishing signaling that UE sends do not received in the base station, gather according to the user's downlink member carrier after changing and to send the PDCCH signaling, and in fact UE does not receive that RRC reshuffles signaling, like this, UE can not resolve according to there being the set of user's downlink member carrier not have to change rule before after receiving the PDCCH signaling, can cause the UE parse error like this.For example, if the set of user's downlink member carrier is A, B, C before changing, be used to represent that carrier wave activates and/or the bit number of deexcitation content equals 3, these three bits are represented A, B and C respectively.Become A, C, D after the set of user's downlink member carrier changes, be used to represent that carrier wave activates and/or the bit number of deexcitation content equals 3, these three bits are represented A, C and D respectively.If UE does not receive RRC and reshuffles signaling, still resolve according to the resolution rules before changing, that UE can think that second bit represent so is carrier wave B, and in the PDCCH signaling that in fact base station sends, be used for representing that carrier wave activates and/or second bit of the bit of deexcitation content represented is carrier wave C.
If be used in the PDCCH signaling representing that the bit number of carrier wave activation and/or deexcitation content equals the carrier number of LTE-A system, perhaps equal system configuration and give set carrier number UE, that do not rely on the set of user's downlink member carrier, even then the set of user's downlink member carrier changes, resolution rules before UE also can change according to the set of user's downlink member carrier parses carrier wave and activates or the deexcitation information content, can not cause the mistake of UE to be resolved.
The set of user's downlink member carrier of UE is the subclass of base station to the carrier set that does not rely on the set of user's downlink member carrier of UE configuration, the base station for the configuration of each UE not rely on the set that user's downlink member carrier set separately changes can be different.
In addition, during a plurality of carrier wave of UE polymerization, can select a up-link carrier to send all upstream control signalings, can be called main carrier together with the paired descending carrier of this up-link carrier, the change of main carrier is if notify the words of UE by the RRC signaling, above-mentioned two kinds of carrier waves that do not rely on user's downlink member carrier set activate or the design of deexcitation signaling, can also avoid the UE main carrier to be changed by the RRC signaling and the influence that brings.
In addition, if in the PDCCH signaling, be used for representing that carrier wave activates and/or the bit number of deexcitation content equals the carrier number 3 that user's downlink member carrier is gathered, employed bit number is less, can reduce expense.
How following mask body introduction is carried carrier wave by various PDCCH signalings and is activated relevant information.
One, the PDCCH signaling comprises Downlink Control Information (Downlink Control Information is called for short DCI) form 0 or DCI form 1A
(1) the I kind activates or the deexcitation granularity
DCI is the signaling that is carried among the PDCCH, and DCI mainly transmits descending or uplink scheduling information, perhaps uplink power control order.DCI comprises multiple form, DCI form 1A and DCI form 0 all comprise stature differentiation bit, it is 1 that the Head Section of DCI form 1A divides the value of bit, and it is 0 that the Head Section of DCI form 0 divides the value of bit, and this two stature is distinguished the form that bit is respectively applied for these two DCI of sign.
The mode that resource allocation field in DCI form 1A and the DCI form 0 adopts continuous resource to distribute, resource allocation field comprises initial Resource Block (Resource Block, abbreviation RB) length of the index number and the RB of distribution, the bit number N that resource allocation field needs BEqual log 2 (N * N+1)/2)Value after rounding up, wherein, N is the RB sum of system bandwidth.Resource allocation field comprises
Figure GSA00000013738600101
The state of kind, comprise a plurality of acquiescence redundant states in these states, so can represent first sign or second sign by the acquiescence redundant state of resource allocation field, wherein first sign is used to indicate the PDCCH signaling to comprise the carrier wave active information, and second sign is used to indicate the PDCCH signaling to comprise carrier wave deexcitation information.For DCI form 0, the RB length that requirement can be dispatched in the existing protocol must be 2,3 or 5 the factor, so the relative form DCI of the state form 1A of acquiescence redundancy is more more in the allocation field of DCI form 0.
In step 102, the PDCCH signaling can comprise DCI form 0 or DCI form 1A, wherein a kind of acquiescence redundant state of resource allocation field of DCI form is represented first sign, and the carrier wave that a kind of Head Section of DCI form divides bit to represent carrier wave active information correspondence activates content; The acquiescence redundant state of the resource allocation field of another kind of DCI form is represented second sign, and the Head Section of another kind of DCI form divides bit to represent the carrier wave deexcitation content of carrier wave deexcitation information correspondence.
This carrier wave activates the concrete expression of content has need to activate for which carrier wave; Similarly, which carrier wave is carrier wave deexcitation contents table be shown with needs deexcitation.
Wherein, the PDCCH signaling can be DCI form 1A, and first sign is represented that by the acquiescence redundant state of the resource allocation field among the DCI form 1A carrier wave activates content and divides bit to represent by the Head Section among the DCI form 1A.The PDCCH signaling can be that DCI form 0, the second sign is represented that by the acquiescence redundant state of the resource allocation field in the DCI form 0 carrier wave deexcitation content divides bit to represent by the Head Section among the DCI form 1A.
Perhaps, the PDCCH signaling can be DCI form 1A, and second sign is represented that by the acquiescence redundant state of the resource allocation field among the DCI form 1A carrier wave district activates content and divides bit to represent by the Head Section among the DCI form 1A.The PDCCH signaling can be that DCI form 0, the first sign is represented that by the acquiescence redundant state of the resource allocation field in the DCI form 0 carrier wave activates content and divides bit to represent by the Head Section among the DCI form 1A.
Because the position of the resource allocation field in DCI form 1A and the DCI form 0 is different, when so the resource allocation field of these two signalings is represented first sign or second sign respectively, need the Head Section in dependent format 1A and 0 to divide bit to represent that carrier wave activates or the deexcitation content, promptly Head Section divides bit to reinterpret.Use the Head Section in DCI form 1A and the DCI form 0 to divide bit to represent that carrier wave activates or the deexcitation content, do not need to distinguish that carrier wave activates and these two kinds of contents of deexcitation, can save the bit in the PDCCH signaling or the use expense of state with other bits in the PDCCH signaling or state.
In step 203, comprise in the PDCCH signaling that the carrier wave by the redundant combination expression of the acquiescence of acquiescence redundant bit, acquiescence redundant state or scrambler and state activates relevant information, specifically can comprise: the acquiescence redundant state of the resource allocation field of a kind of DCI form among DCI form 0 or the DCI form 1A is represented first sign, and the acquiescence redundant state of the resource allocation field of the another kind of DCI form among DCI form 0 or the DCI form 1A is represented second sign.
The then definite carrier wave of set pattern activates the content that relevant information is represented to UE according to being provided with really, specifically can comprise: the value of dividing bit according to the Head Section of DCI form corresponding identification that comprises in the PDCCH signaling and DCI form, determine that carrier wave activates the content that relevant information is represented, wherein, divide the value of bit to determine that it is that carrier wave activates content that carrier wave activates the content that relevant information represents according to first sign and the Head Section of DCI form, the content of dividing the value of bit to determine that carrier wave activation relevant information is represented according to the Head Section of second sign and DCI form is a carrier wave deexcitation content.
(2) the II kind activates or the deexcitation granularity
In this case, carrier wave activation relevant information comprises the 3rd sign; The 3rd sign is used for indicating the PDCCH signaling to comprise in carrier wave active information and the carrier wave deexcitation information at least one.The PDCCH signaling comprises DCI form 1A or DCI form 0, and the acquiescence redundant state of resource allocation field is represented the 3rd sign in DCI form 1A or the DCI form 0, and all the other bits except resource allocation field or field represent that carrier wave activates and/or the deexcitation content; Wherein, carrier wave activates the corresponding carrier wave active information of content; The corresponding carrier wave deexcitation of carrier wave deexcitation content information.
Owing to comprise the 3rd sign in DCI form 1A or the DCI form 0, so the implication of other each bit in DCI form 1A and the DCI form 0 need redefine, other bits except resource allocation field or state can carry carrier wave and activate content and/or deexcitation content.For example, for DCI form 0 and form 1A, except resource allocation field is represented the 3rd sign, can adopt other bit or field except resource allocation field to represent that carrier wave activates and/or the deexcitation content.
Can also carry CRC information in the PDCCH signaling, wherein, CRC is meant some bit is changed to fixing value, as is changed to " 0 ", can also carry more other information.
In the step 203, comprise in the PDCCH signaling that the carrier wave by the redundant combination expression of the acquiescence of acquiescence redundant bit, acquiescence redundant state or scrambler and state activates relevant information, specifically can comprise: comprise the 3rd sign of being represented by the acquiescence redundant state of resource allocation field among DCI form 0 or the DCI form 1A.
The then definite carrier wave of set pattern activates the content that relevant information is represented to UE according to being provided with really, comprise:, determine that carrier wave activates the content that relevant information is represented according to other bits except resource allocation field or the value of state among the DCI form 0 of PDCCH signaling or the DCI form 1A.
Two, the PDCCH signaling is DCI form 0 or DCI form 1A
(1) the I kind activates or the deexcitation granularity
In step 102, carrier wave activates relevant information and specifically comprises carrier wave active information or carrier wave deexcitation information, and the carrier wave active information comprises first sign, and carrier wave deexcitation information comprises second sign; One of resource allocation field acquiescence redundant state is represented first sign in the DCI form of PDCCH signaling, and another acquiescence redundant state of resource allocation field is represented second sign in the DCI form; The DCI form is DCI form 0 or DCI form 1A.
That is to say, represent first sign and second sign with two acquiescence redundant states of resource allocation field in the DCI form 0 respectively.
Perhaps, under activation of I kind or deexcitation granularity, in step 102, carrier wave activates relevant information and comprises the 3rd sign; One of resource allocation field acquiescence redundant state is represented the 3rd sign in the DCI form of PDCCH signaling, activates and/or the deexcitation content except resource allocation field and Head Section divide other bits or state representation carrier wave the bit in the DCI form; The DCI form is DCI form 0 or DCI form 1A.
That is to say, represent to carry among this DCI form 0 or the DCI form 1A carrier wave with an acquiescence redundant state of the resource allocation field of DCI form 0 or DCI form 1A and activate relevant information, using what divide that another bit the bit represents to carry in the PDCCH signaling except resource allocation field and Head Section is that carrier wave activates content or carrier wave deexcitation content.
Be that example is introduced with the former below:
For example, if a kind of acquiescence redundant state S1 of the resource allocation field in the DCI form 0 represents that carrier wave activates this sign, another kind of acquiescence redundant state S2 represents this sign of carrier wave deexcitation.When UE received the PDCCH signaling, if resource allocation field is the S1 state, then UE can determine the needs general except when preceding n-1 the carrier wave that is in outside the state of activation carrier wave that is used for the bearing activation signaling all activates.If resource allocation field is the S2 state, then UE can determine n-1 carrier wave deexcitation need be kept a carrier wave activation.
In step 203, comprise in the PDCCH signaling that the carrier wave by the redundant combination expression of the acquiescence of acquiescence redundant bit, acquiescence redundant state or scrambler and state activates relevant information, specifically can comprise: one of resource allocation field acquiescence redundant state is represented first sign among DCI form 0 or the DCI form 1A, and another acquiescence redundant state is represented second sign;

Seven, the PDCCH signaling is to use the PDCCH signaling of semi-continuous scheduling scrambler-sub-district-RNTI (SPS-C-RNTI) scrambling
The opening and closing of semi-continuous scheduling (Semi-Persistent Scheduling is called for short SPS) are disposed by the RRC signaling, and after SPS opened, UE can detect the PDCCH signaling of SPS-C-RNTI scrambling.The PDCCH signaling that is used to the SPS that activates and reshuffle is by the SPS-C-RNTI scrambling, wherein NDI is changed to 0, the fixed bit that also has 6 extra bits as virtual CRC check position (at time division duplex (Time Division Duplex, abbreviation TDD) this fixed bit is 7 bits in the system), the value of this 6 bit is fixed.For example, for DCI form 1A, under frequency division duplex system, the HARQ process field of 3 bits, the RV field of 2 bits, the highest order of 5 bit MCS fields, the value of this 6 bit is fixed as 0; Be used for the professional PDCCH signaling that retransmits of SPS by the SPS-C-RNTI scrambling, wherein NDI is changed to 1.

Under the situation that the SPS business is closed, do not needed the PDCCH signaling of SPS-C-RNTI scrambling, so activating relevant information, carrier wave represents by bit or field in the PDCCH signaling of SPS-C-RNTI scrambling.All bits or field in the PDCCH signaling of SPS-C-RNTI scrambling can reinterpret.That is to say that under the situation that the SPS business is closed, the signaling of the PDCCH of SPS-C-RNTI scrambling has had the function that is different under the professional situation of opening of SPS.
The PDCCH signaling of reusing the SPS-C-RNTI scrambling is compared with the PDCCH signaling of C-RNTI scrambling as the signaling that is used for carrier wave activation or deexcitation, can reduce false alarm probability; And will use 6 virtual CRC check position states in the PDCCH signaling of SPS-C-RNTI scrambling to be inverted, can further reduce false alarm probability; Simultaneously, little with respect to the resource allocation field expense in the PDCCH signaling of utilizing the SPS-C-RNTI scrambling, the efficient that reinterprets utilization of other fields improves.
In the prior art, the configuration information of UE sends to UE by the base station by semi-static RRC signaling, UE is receiving that correctly RRC connects configuration (RRC Connection Reconfiguration) signaling and will operate accordingly according to configuration information, but the base station only could have been determined after (RRC Connection Reconfiguration Complete) signaling is finished in configuration the configuration successful of UE receiving that RRC that UE sends connects.That is to say, in the time of two signalings, the base station can't determine whether UE has correctly received RRC and connected configuration signal, the base station just can't determine that also need receive RRC according to UE connects before the configuration signal configuration parameter of UE UE is dispatched, still need receive RRC connection configuration signal configuration information afterwards according to UE UE is dispatched, thereby can cause the base station fuzzy the scheduling of UE.
In order to solve the fuzzy problem of above-mentioned scheduling, carrier wave provided by the invention activates in the processing method of relevant information, and the base station sends in the PDCCH signaling of UE and activates the relevant information except carrying carrier wave, can also carry the configuration information of UE.Because in the embodiment of the invention, carry carrier wave in the PDCCH signaling and activate relevant information, so can reinterpret except carrier wave activates the bit of relevant information or other bits the state or state in the PDCCH signaling just can be used for carrying the configuration information of these UE.
These configuration informations can comprise the transmission mode, main carrier of carrier wave change corresponding relation between the configuration information of the search volume of information, UE, PDCCH monitoring collection (PDCCH monitoring set), UE downlink member subclass, PDCCH monitoring collection and the UE downlink member subclass, to the schedule information of carrier wave.
Introduce the carry mode of these configuration informations in the PDCCH signaling below respectively.
(1) in the PDCCH signaling that carries carrier wave activation relevant information, carries the carrier transmission pattern information
Introduced the multiple PDCCH signaling that can carry carrier wave activation relevant information among the aforesaid embodiment, the transmission mode information that other bits in these signalings except carrying carrier wave activation relevant information or state can be used to carry some carrier wave.The base station sends to UE with the PDCCH signaling, and UE activates relevant information except receiving carrier wave, can also receive the carrier transmission pattern information, sends the RRC signaling separately and sends the carrier transmission pattern information and need not the base station, has avoided the scheduling of base station fuzzy.
Being example with carrier dispatching.Be meant that with carrier dispatching control channel on certain carrier wave only to dispatch the data of this carrier wave or the up-link carrier corresponding with this carrier wave, that is to say, control channel and its can data dispatching carrier wave have one-to-one relationship.Under scene with carrier dispatching, suppose to have 2 carrier waves in the set of user's downlink member carrier, form 1 under the transmission mode of carrier wave C1 and form 0/1A, form under carrier wave C2 (C2 the is in deactivation status) current transmission mode is 2 and 0/1A, change the transmission mode of C2 if desired and activate C2, its form is changed to form 2 and 0A (supposing that the Uplink MIMO form is 0A), can carry the carrier wave active information this moment by the mode in the previous embodiment in PDCCH, and in the PDCCH signaling, carrying transmission mode information, notice UE changes the pattern of C2.Like this, the base station can determine that promptly UE can correctly receive this transmission mode information after issuing PDCCH, and need not to wait for that affirmation that UE returns receives the affirmation signaling of transmission mode information, the base station issues after the PDCCH signaling, in the time of need dispatching UE, promptly can dispatch for UE configuration information afterwards, avoid the scheduling of base station fuzzy according to issuing the PDCCH signaling to UE.
Supposing that each carrier wave is descending has seven kinds of transmission modes, up have two kinds of transmission modes, then each carrier wave need be used 3+1=4 bit at least, represents that seven kinds of descending transmission modes need at least 3 bits, represents that two kinds of up transmission modes need at least 1 bit.
At present, the fall-back mode of LTE is form 0/1A, has arrived LTE-A, if fall-back mode is variable, for example 2A is used as fall-back mode under the MIMO.So dynamic signaling can 1 bit the indication fall-back mode be 0 or 1A, or 2A.
(2) in the PDCCH signaling that carries carrier wave activation relevant information, carry main carrier and change information
Can define the specific main carrier of one or more UE (descending) for UE in the LTE-A system, the feature of this main carrier can be: the paired descending carrier of up-link carrier that is used to send ascending control channel, perhaps the common search space is only detected on main carrier, or the like.
Main carrier changes information and can be carried in the PDCCH signaling by following mode:
(1) other bits except the bit that carries carrier wave activation relevant information and carrier wave activation and/or deexcitation content or state carry main carrier change information in the PDCCH signaling that carries carrier wave activation relevant information.The carrier aggregation wave number of supposing the UE maximum is 5, then needs 3 bits to carry main carrier at least and changes information.
(2) send on need be and carry the PDCCH signaling that carrier wave activates relevant information as the carrier wave of main carrier
Suppose to have 3 carrier waves in the set of active user's downlink member carrier, the carrier wave that is in state of activation is C1 and C2, and carrier wave C3 is in deactivation status.If send the PDCCH signaling that is used to activate C3 on carrier wave C2, then UE can determine that carrier wave C2 is current main carrier.
(3) carry carrier wave activate carry scheduling among the PDCCH of relevant information need be as the information of the carrier wave of main carrier
Suppose to have 3 carrier waves in the active user's downlink member carrier set, send the PDCCH signaling that is used for scheduling carrier wave C2 and carries the information that is used to activate carrier wave C3 on carrier wave C1, then UE can determine that carrier wave C2 is the main carrier of UE.
(3) activate the configuration information that carries the specific search volume (this search volume is different from the common search space) of UE on some carrier wave in the PDCCH signaling of relevant information carrying carrier wave, perhaps carry the configuration information of the search volume of some specific control channel form
The PDCCH blind Detecting number of times and the PDCCH that consider UE in order to compromise dispatch blocking rate, can adjust the size of PDCCH search volume.If current PDCCH scheduling blocking rate is bigger, then under the prerequisite that is no more than the maximum blind Detecting ability of UE, the suitable size in expanded search space; If current PDCCH scheduling blocking rate is very little, in order to reduce the PDCCH blind Detecting of UE, be the UE power saving, can suitably dwindle the size of search volume.Illustrate, two PDCCH of UE have search volume separately on a carrier wave, and when the signaling of two PDCCH was uneven in length, UE can search for PDCCH separately in two PDCCH search volumes separately; When the signaling equal in length of two PDCCH, two search volumes can be shared, be UE can detect this same signaling length in two search volumes two PDCCH, because this moment, the dispatching flexibility situation that detects PDCCH separately than the separate searches space of PDCCH increased to some extent, so can dwindle the search volume this moment, reduce the blind Detecting number of times of PDCCH, between blind Detecting number of times and PDCCH scheduling blocking rate, compromise.The size in concrete two separate searches spaces of hypothesis (search volume 1 and search volume 2) all is 6 control channel unit (Control Channel Element, be called for short CCE), when the signaling of two PDCCH is uneven in length, then UE detects a PDCCH in search volume 1, detects the 2nd PDCCH in search volume 2; When the signaling equal in length of two PDCCH, UE can detect a PDCCH and the 2nd PDCCH (signaling length equals the 2nd PDCCH) in whole two search volumes, can dispose whole search volume size this moment for certain value less than 6*2, such as 9.
Particularly, also can be divided into several levels to the search volume on each carrier wave, for example can be divided into three ranks, be respectively search volume size and be higher than search volume size in the normal LTE system in the size of search volume in the normal LTE system, the subnormal LTE system.Need at least 2 bits to notify for each carrier wave; Also can adjust the configuration information of the search volume of certain specific control channel form, for example, change the search volume size of total form 0/1A.
Further, the reliability of considering the PDCCH signaling is not as semi-static RRC signaling, in order the scheduling of base station to occur not interrupting under the wrong situation in the transmission of PDCCH signaling, can not change the search volume on the main carrier, perhaps not change the search volume of the control channel form that can on main carrier, transmit.
In addition, the blind Detecting number of times of each carrier wave also can carry in the PDCCH signaling that carries carrier wave activation relevant information.
(4) in the PDCCH signaling that carries carrier wave activation relevant information, carry PDCCH monitoring set, also can carry the corresponding relation between the set of PDCCH monitoring collection and user's downlink member carrier, i.e. each downlink data carriers in user's downlink member carrier set and upstream data carrier wave (if any) the pairing PDCCH paired with it can be carried on which or which carrier wave of PDCCH detection set.
The carrier number of considering the maximum polymerization of UE is 5, needs at least 5 bits to carry PDCCH monitoring set.Consider the reliability of PDCCH signaling, main carrier can not change, and so just needs 4 bits to carry PDCCH monitoring set.Perhaps, the bit number that is used for carrying PDCCH monitoring set can equal the carrier number that does not rely on the set of user's downlink member carrier that system is the UE configuration.
For carrying of the corresponding relation between PDCCH monitoring collection and the set of user's downlink member carrier, under a kind of situation, the number of bits that is used to carry the corresponding relation of user's downlink member carrier set between gathering with the PDCCH monitoring is N*M, N is the carrier number in the set of user's downlink member carrier, and M is the carrier number of PDCCH monitoring set.In another case, consider the reliability of PDCCH signaling, the corresponding relation of the control channel form that can transmit on main carrier does not change, and the number of bits that is used to carry the corresponding relation between UE downlink member subclass and the PDCCH monitoring set can be (N-1) * M.Under another situation, consider that the corresponding relation with carrier dispatching can exist always, the number of bits that then is used to carry the corresponding relation of user's downlink member carrier set between gathering with the PDCCH monitoring can be (N-1) * M.In like manner, above-mentioned three kinds of situations also can be taken all factors into consideration.The carrier number of supposing the maximum polymerization of UE is N=M=5, and the number of bits that is used to carry the corresponding relation between the set of user's downlink member carrier and the PDCCH monitoring set under then above-mentioned three kinds of situations is respectively 5*5=25, (5-1) * 5=20 and (5-1) * 5=20.
Distinguishingly, if the set of user's downlink member carrier is adopted man-to-man corresponding relation with PDCCH monitoring set, then need N*|log 2M| bit, || for rounding up.Consider that the corresponding relation with carrier dispatching exists always, the bit number that needs can further reduce, and is specially (N-M) * | log 2M| bit, || for rounding up, also can be taken as max[(N-M) * | log 2M|] individual bit, wherein the PDCCH monitoring set that can get of M and the N system of being respectively and the carrier number in the set of user's downlink member carrier, the system that perhaps is taken as is the carrier number that user's downlink member carrier is gathered that do not rely on of UE configuration.
Be illustrated in figure 3 as the corresponding relation schematic diagram of the user's downlink member carrier set that relates in the embodiment of the invention between gathering with the PDCCH monitoring, suppose N=4, M=2, the bit number that is used to carry the corresponding relation of user's downlink member carrier set between gathering with the PDCCH monitoring can be 4*2=8, the bit number that changes PDCCH monitoring set is 4, a remaining 16-8-4=4 bit can be made as definite value, for example can be set to 0, as virtual CRC check.Among Fig. 3, before corresponding relation changed, the data and the control information of carrier wave C3 correspondence were all transmitted on carrier wave C3, and the data on the carrier wave C4 are transmitted on carrier wave C4, and the control information on the carrier wave C4 is transmitted on carrier wave C3.After corresponding relation changes, carrier wave C3 no longer is the member that the PDCCH monitoring is concentrated, carrier wave C4 has become the member that the PDCCH monitoring is concentrated, so the data and the control information of carrier wave C4 correspondence are transmitted on carrier wave C4, data on the carrier wave C3 are transmitted on carrier wave C3, and the control information on the carrier wave C3 is transmitted on carrier wave C4.
(5) in the PDCCH signaling that carries carrier wave activation relevant information, carry carrier dispatching information
Activate the schedule information of the carrier wave that can carry this PDCCH simultaneously in the PDCCH signaling of relevant information and dispatched carrying carrier wave, or stride carrier dispatching information.Especially; expansion carrier wave (the carrier wave that the expansion carrier wave may be made up of the boundary belt between a plurality of member carriers; and can not insert for UE separately; but use to depend on other access carriers only) but information that activation on the access carrier that depended on or deexcitation signaling can be carried this expansion carrier wave of scheduling, and the PDCCH signaling that carries carrier wave activation relevant information on rf chain on certain carrier wave can carry the schedule information of other carrier waves on this rf chain.
Concrete data dispatch can be divided into 3 classes:
(1) if activates relevant information by these two the incompatible expression carrier wave of acquiescence redundancy group of the redundant bit of acquiescence, acquiescence redundant state or scrambler and state, then the PDCCH signaling can be carried the data dispatch information of current certain carrier wave, activates deexcitation signaling place carrier wave as scheduling.As adopt the acquiescence redundant state in the carrier wave indication bit to represent that carrier wave activates relevant information, then can carry the schedule information that is used to dispatch certain current carrier wave except other field of carrier wave indication bit; In addition, if adopt the state of the acquiescence redundancy in the resource allocation field to represent that carrier wave activates deexcitation information, then the PDCCH signaling can be carried the carrier dispatching information of simplification.Wherein, the resource allocation field in the PDCCH signaling of resource allocation field and last scheduling is identical.
For example, represent that carrier wave activates relevant information if adopt the resource allocation field among DCI form 0 and the DCI form 1A, and divide bit to represent that carrier wave activates or the deexcitation information content with the Head Section among DCI form 0 and the DCI form 1A, then the PDCCH signaling can be done the descending scheduling of simplification, this descending scheduling is asynchronous HARQ, the such fixed timing relationship of uplink synchronous HARQ needn't be arranged, and necessarily have the control channel scheduling.If DCI form 1A is as the PDCCH signaling that is used to activate carrier wave and while dispatching downlink data, stipulate that then resource allocation field is identical with resource allocation field in the last PDCCH signaling, the explanation of other fields is constant, NDI indicates re-transmission, differing in size in the size of last transmission block of MCS+ resource allocation field, such PDCCH signaling are the signalings that carrier wave activation or deexcitation are carried out in simple being used to.If DCI form 0 is also dispatched the PDCCH signaling of small-sized data simultaneously as the deexcitation carrier wave, stipulate that then the resource allocation field in the control channel of resource allocation field and last scheduling is identical, other fields change descending correspondence into and explain, promptly centralized/distributed resource allocation sign=frequency hopping sign, the skew of HARQ process=demodulation pilot frequency, the filling bit of RV=(indication of non-periodic channel quality)+may exist; NDI indicates re-transmission, and the MCS+ resource allocation field is not equal to last transmission block size, and such PDCCH signaling both can have been carried out carrier wave and activated or deexcitation, can dispatch again.If carrier wave activates or the deexcitation signaling is dispatched to be used as retransmission packet only, then the NDI of 1 bit just can be used for the indication of up-downgoing retransfer scheduling.
(2) if adopt signaling length greater than the DCI signaling of total form DCI0 or DCI1A when carrying carrier wave and activate the PDCCH signaling of relevant information, for example, adopt DCI form 2 or DCI form 2A (wherein swap_flag or certain NDI activate as carrier wave or the deexcitation sign), the field that can comprise each field that is used to represent DCI form 0 or DCI form 1 in this PDCCH signaling, that is to say this PDCCH signaling can " rollback " dispatching office at carrier wave.So-called " rollback " scheduling, in two kinds of available DCI forms that under certain current transmission mode, comprise exactly, the data dispatch that adopts form 0 or form 1A to carry out.For example, current transmission mode is a closed-loop MIMO, and the form that comprises is DCI 2 and DCI 0/1A, and this moment, the base station was carried out " rollback " scheduling with DCI form 0 or form 1A to UE owing to the influence of channel status.In two kinds of available DCI forms that comprise under certain current transmission mode, a kind of DCI form is relevant with transmission mode, and another kind of DCI form is DCI form 0 and form 1A total between various transmission modes.
Suppose to adopt exchange identification to represent that carrier wave activates or the deexcitation sign, from DCI form 1, DCI form 2 or the DCI form 2A of this class signaling length, can reinterpret " rollback " scheduling that a DCI form 0 or DCI form 1A do signaling place carrier wave greater than DCI form 0 or DCI form 1A.Be illustrated in figure 4 as and carry carrier wave in the embodiment of the invention and activate relevant information and be used to represent the DCI form 1 of each field of DCI form 0 or DCI form 1 or the structural representation of DCI form 2 or DCI form 2A, among the figure, in DCI form 1 or DCI form 2 or DCI form 2A, obtain the activation relevant information except the carrier wave activation and (can comprise first sign, second sign and the 3rd sign, except perhaps deexcitation content in the carrier wave activation, also comprise the field of each field that is used to represent DCI form 0 or DCI form 1, be equivalent in DCI form 1 or DCI form 2 or DCI form 2A, comprise DCI form 1A or DCI form 0.
(3) when striding carrier dispatching, needing to add carrier wave indication bit position (CarrierIndicator Field, be called for short CIF) in the PDCCH signaling, to notify this PDCCH be the transfer of data of specifically dispatching which carrier wave.Comprise two carrier wave C1 and C2 such as in the user's downlink member carrier set, general, can stride transfer of data on the carrier dispatching C2 by the indication of CIF in the PDCCH signaling that sends on the C1.At this moment, if for UE, C1 is an activated state, and C2 is a deactivated state, then can activate C2 by the CIF that is used to refer to C2 among the PDCCH that sends this moment on C1, and dispatch the transfer of data on the C1 simultaneously.General, can activate the carrier wave of certain deactivated state and the transfer of data that can dispatch this PDCCH signaling place carrier wave simultaneously by the PDCCH that strides carrier dispatching that CIF realizes.Do like this and can save signaling consumption.
(6) in the PDCCH signaling that carries carrier wave activation relevant information, carry the channel quality information resource allocation information of (Channel Quality Information is called for short CQI)
Carry out the CQI that the descending scheduling of UE depends on the up feedback of UE the base station.The CQI of UE feedback is divided into periodically CQI and aperiodicity CQI in the LTE system.Periodically the resource of CQI is that the proprietary signaling configuration of RRC is passed through in the base station, generally be transmitted in Physical Uplink Control Channel (Physical UplinkControl Channel, be called for short PUCCH) in, when existing upstream data to send simultaneously, then catch up with line data together multiplexing transmission go physically in the shared channel (Physical Uplink Control Channel is called for short PUSCH); For aperiodicity CQI, the base station can not remain for transmitting the resource of aperiodicity CQI in advance for UE, but comes Resources allocation by dynamic PDCCH scheduling (uplink scheduling), transmits in PUSCH.When existing upstream data to send simultaneously, then aperiodic CQI catch up with line data together multiplexing transmission on the resource of dynamic assignment, aperiodic CQI with the identical modulation system of upstream data employing, aperiodic, the code check of CQI was adjusted according to the code check of data; When not existing upstream data to send, then on the resource of distributing, only send CQI aperiodic, to be QPSK, according to the RB number of Resources allocation determine only by code check for modulation system.
Because CQI is divided into periodically and two kinds of aperiodicity, is divided into two kinds of situations below and introduces.
(1) periodically CQI has adopted in the LTE-A system of carrier aggregation technology, for periodicity CQI, the base station disposes the resource that is used to send CQI that is independent of carrier wave and UE (resource that is used to send CQI is the resource allocation information of CQI just) for each descending carrier in the user's downlink member carrier set with the proprietary signaling of RRC usually on a up-link carrier.This mode need be UE configuration CQI resource allocation information with proprietary RRC signaling, in fact, can carry carrier wave fully and activate the resource allocation information that carries CQI in the PDCCH signaling of relevant information in various embodiments of the present invention, the PDCCH signaling of carrying the CQI resource allocation information can be the descending PDCCH signaling that carries the carrier wave active information.
The base station can be distributed to the CQI resource of each UE according to the statistic multiplexing rule judgment, and the resource allocation information of CQI is carried in the PDCCH signaling.
So-called statistic multiplexing is meant the base station in advance for a plurality of UE have distributed an identical channel resource set that is used to send CQI, and the resource in this set can be less than the sum of the resource requirement of this a plurality of UE; The use of a plurality of UE to this resource collection coordinated by certain rule in the base station, specifically notifies the resource of each its current use of UE by dynamic signaling, improved efficiency of resource.
So-called statistic multiplexing rule is meant, a plurality of UE can shared some CQI resource (this shared CQI resource can be disposed to UE by the proprietary signaling of RRC by the base station), and the base station is that current UE need guarantee that this CQI resource do not used by other UE when distributing the CQI resource.This rule can be determined according to the demand of LTE-A system.
The carrier wave of deexcitation is need not feed back CQI at it, and when having activated certain carrier wave, notice UE should activate the CQI resource of carrier wave correspondence in current PDCCH signaling.Illustrate, the base station can be given UE1 and UE2 4 CQI resource allocations on the up-link carrier, to be in the carrier wave of activated state be respectively carrier wave C1 and carrier wave C2 for UE1 and UE2 during beginning, corresponding CQI resource is respectively CQI1 and CQI2, when the carrier wave C2 of UE1 was activated by the PDCCH signaling in the base station, the CQI resource of notice carrier wave C2 was CQI3 in the PDCCH signaling simultaneously; In like manner, when the carrier wave C3 of UE2 was activated by the PDCCH signaling in the base station, the CQI resource of notice C3 was CQI4 in signaling simultaneously.
In the embodiment of the invention, in carrying the PDCCH signaling of carrier wave active information, carry the periodically resource allocation information of CQI, only use a PDCCH signaling promptly can realize activating the function of the resource of carrier wave and configuration cycle property CQI, saved expense.And the CQI resource of base station assigns can guarantee when making full use of CQI that according to the statistic multiplexing regular allocation each UE can both be assigned to the CQI resource, has improved the utilance of CQI resource.
(2) aperiodicity CQI
In the prior art, aperiodic, the scheduling of CQI was to realize by the DCI form 0 that is used for uplink scheduling, bit in the DCI form 0 in the concrete FDD system comprises: the Head Section of 1 bit divides bit, the frequency modulation sign of 1 bit, and resource allocation field comprises N bit, N is determined by system bandwidth, modulation coding mode 5 bits, new data packets is indicated 1 bit, and the power control is worth 2 bits, demodulation pilot frequency cyclic shift 3 bits, aperiodic, CQI triggered 1 bit.
In embodiments of the present invention, can aperiodic CQI resource allocation information be placed in the PDCCH signaling that carries the carrier wave active information, can pare down expenses like this, because only need this moment the shared resource of notice CQI aperiodic to get final product, other field in the prior art in the DCI form 0 can save.
(7) activate to carry in the PDCCH signaling of relevant information and be used to trigger UE and send detection reference signal (Sounding Reference Signal, resource allocation information SRS) and be used to trigger the trigger message that UE sends SRS carrying carrier wave
Carry out the SRS that the uplink scheduling of UE depends on the up transmission of UE the base station.The resource allocation information of SRS is on last symbol of each subframe in the prior art, and a plurality of UE can pass through the time-division, and frequency division and sign indicating number are assigned to multiplexing, transmit according to the parameter of RRC configuration signal.
Adopted in the LTE-A system of carrier aggregation technology, be used for the resource-constrained of transmitting SRS, need to consider to increase the resource that is used for transmitting SRS, a scheme is to come transmitting SRS by the cyclic shift of demodulation pilot frequency, just need trigger the transmission of SRS on cyclic shift this moment, can in the PDCCH signaling of carrying carrier wave activation relevant information, carry the resource allocation information (resource allocation information is the cyclic shift of the concrete demodulation pilot frequency that distributes) of SRS transmission and be used to trigger the trigger message that UE sends SRS.
In the embodiment of the invention, in carrying the PDCCH signaling of up-link carrier active information, carry and be used to trigger the trigger message of UE transmission SRS and the resource allocation information of SRS, can dynamically trigger UE and send SRS, the resource allocation information of SRS dynamically is notified to UE, and owing to do not need to use separately other signaling to transmit this trigger message and resource allocation information, but with the shared signaling of carrier wave active information, saved expense.
In addition, the base station can be according to up carrier set of the upstream traffic of UE configuration, i.e. dispatching uplink data in this set, and corresponding UE need send SRS on the carrier wave during this is gathered.Accordingly, the base station can send SRS for UE and activate dynamically or deactivating operation in up carrier set.For example, the base station has disposed 3 up-link carriers (comprising C1C2 and C3) according to the average traffic in certain period of UE to UE and corresponding SRS resource sends SRS for UE, when the UE traffic carrying capacity hour, the base station can send the SRS operation by deexcitation UE on certain several carrier wave, only allow UE send SRS on C1 such as the base station; When the UE traffic carrying capacity was big, the operation that other two carrier waves of UE send SRS can be opened in the base station, and promptly UE will send SRS on 3 carrier waves.In the present embodiment, the base station can be controlled UE dynamically and send SRS, has optimized the utilization of resources, has saved signaling consumption.
