Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Various technologies described herein can be used for various wireless communication systems, such as current 2G, and 3G communication system is under Generation communication system, such as global system for mobile communications (GSM, global system for mobile Communications), CDMA (CDMA, code division multiple access) system, time division multiple acess (TDMA, time division multiple access) system, wideband code division multiple access (WCDMA, wideband code Division multiple access wireless), frequency division multiple access (FDMA, freque ncydivision multiple Addressing) system, orthogonal frequency division multiple access (OFDMA, orthogonal freque ncy-division multiple Access) system, Single Carrier Frequency Division Multiple Access (SC-FDMA) system, General Packet Radio Service (GPRS, general packet Radio service) system, long term evolution (LTE, long term evolution) system and other such communication systems System.
User equipment can be wireless terminal and be also possible to catv terminal, and wireless terminal can be directed to user and provide language The equipment of sound and/or data connectivity has the handheld device of wireless connecting function or is connected to radio modem Other processing equipments.Wireless terminal can through wireless access network (for example, RAN, radio access network) with one or Multiple cores net is communicated, and wireless terminal can be mobile terminal, such as mobile phone (or be " honeycomb " phone) and is had The computer of mobile terminal, for example, it may be portable, pocket, hand-held, built-in computer or vehicle-mounted mobile dress It sets, they exchange language and/or data with wireless access network.For example, personal communication service (PCS, personal Communication service) phone, wireless phone, Session initiation Protocol (SIP) phone, wireless local loop (WLL, Wireless local loop) it stands, the equipment such as personal digital assistant (PDA, personal digital assistant).Nothing Line terminal is referred to as system, subscriber unit (subscriber unit), subscriber station (subscriber station), moves Dynamic station (mobile station), mobile station (mobile), distant station (remote station), access point (access Point), remote terminal (remote terminal), access terminal (access terminal), user terminal (user Terminal), user agent (user agent), user equipment (user device) or user equipment (user equipment)。
In LTE communication system, there are CA (Carrier Aggregation, carrier wave polymerization) technologies, i.e., two or two A above member carrier, which can condense together, to be transmitted for data to support bigger bandwidth, the member carrier of these polymerizations It can be simultaneously a user service, carry out the transmitting-receiving of data.Existing CA system is that the carrier wave under the same base station is polymerize, Or have carrier wave polymerization between the cell of the ideal eNodeB returned, such as master base station MeNodeB and prothetic group station SeNodeB it Between pass through optical fiber connect.It can be under ideal passback deployment, between eNodeB or between the different community of the same eNodeB Realize timely information exchange, and the downlink timing of multiple cells is synchronous in CA system.
In CA system, since the signal of the different community for user equipment service reaches the propagation delay of user equipment not Together, thus by for multiple cells of user equipment service according to its signal reach user equipment propagation delay different demarcation at Different TAG.
Cell at the same TAG, user equipment adjust determining for its up channel according to common timing advance order When.In existing CA system, if the cell for the up channel that user equipment emits simultaneously belongs to multiple TAG, belong to not It is no more than the length of a symbol with the timing difference of the up channel of the cell of TAG.As shown in Figure 1, in the subframe of TAG1 The last symbol (color burn part) of the up channel of subframe i is just likely to the subframe subframe with TAG 2 First symbol of the up channel of i+1 has part to overlap, the last symbol of the up channel of the subframe i of TAG1 It also partly overlaps simultaneously with the last symbol of the up channel of the subframe i of TAG2.
In existing CA technology, when the uplink transmission power of user equipment is more than the maximum transmission power that user equipment allows When, user equipment needs to carry out power compression, to meet maximum transmission power limitation.For the superimposed symbols under different TAG, when When the transmission power of user equipment is more than its maximum transmission power, user equipment carries out following processing:
(1) if had in superimposed symbols comprising SRS's (Sounding Reference Symbol, detection reference signal) Symbol, the symbol can be dropped.
(2) when belong to a TAG sub-frame of uplink send PUCCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel), the sub-frame of uplink for belonging to another TAG sends PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel), user equipment needs to guarantee the transmitting function of the different laps of the symbol of overlapping Rate is no more than maximum transmission power.
(3) when the sub-frame of uplink for belonging to a TAG sends PRACH (Physical Random Access Channel, object Manage random access channel), the sub-frame of uplink for belonging to another TAG sends PUSCH/PUCCH, and user equipment needs to adjust PUSCH/ The power of PUCCH is no more than maximum transmission power with the transmission power for guaranteeing lap.
For second and third above-mentioned point, according to the priority of channel in power compression, the transmission power of user equipment needs The preferential power for guaranteeing PRACH, followed by PUCCH, last PUSCH.That is, the power of PUSCH can be compressed at first.
Processing for above-mentioned user equipment to sub-frame of uplink, eNodeB after receiving the sub-frame of uplink of user equipment, ENodeB detects the power in the subframe of PUSCH channel with the superimposed symbols for the subframe for belonging to other TAG, and with the son The power of other symbols is compared in frame.When power of the power of the superimposed symbols significantly lower than the subframe other symbols, The power of the superimposed symbols is compensated, then is decoded together with other symbols of the subframe.
In existing CA technology, the timing of different cells is synchronous, and because being ideal passback, under different TAG The overlapping situation of the sub-frame of uplink of user equipment and the power compression situation that may occur are also for eNodeB can be pre- Phase.
However, in doubly-linked connection technology (the carrier wave polymerization as between base station, and be non-ideal passback connection between base station, The downlink timing of different base station does not require be synchronous), the cell under different base station is not belonging to the same TAG, therefore, uses The sub-frame of uplink that family equipment is sent to two eNB can overlap.Again due to being non-ideal passback connection, different base station between base station Downlink timing do not require must be it is synchronous, i.e., base station downlink timing may be it is asynchronous, therefore, user equipment is sent to not It is greater than the range of a symbol with the overlapping region of the subframe of the cell of TAG.Also, due to the non-ideal passback connection between base station The reason of, the downlink timing of base station and the base station to user equipment some subframe dispatch situation, for another base It is unknown for standing.The distinct symbols set for the sub-frame of uplink that user equipment is sent due to the difference that belongs to another TAG Sub-frame of uplink part it is overlapping and different power compressions can have been can be carried out, cause the transmitting of the distinct symbols in a subframe Power is different.Base station causes base station to receive and demodulate due to that can not know the assemble of symbol that may have different capacity to be arranged The PUSCH of the subframe causes difficulty.In addition, since base station does not know the power setting situation of distinct symbols, for high order modulation Demodulation, base station needs to know the amplitude information of modulation symbol, therefore influences demodulation performance.
Illustratively, as shown in Fig. 2, the subframe subframe i of subframe the subframe i+1 and TAG1 of TAG2 and Subframe i+1 occurs to overlap, and overlapping region is overlap portion1 and overlap portion 2 respectively.In order to Meet the maximum transmission power limitation of user equipment, user equipment all must satisfy in different overlapping regions is no more than maximum hair Penetrate power.And since the difference of overlapping region, overlap portion 1 and overlap portion 2 are possible to carry out Different power settings.Base station is due to that can not know the assemble of symbol overlap portion that may have different capacity to be arranged 1 and overlap portion 2, the PUSCH for causing base station to receive and demodulate the subframe cause difficulty.
In existing doubly-linked connection technology, the function of the distinct symbols for the subframe that base station uses blind Detecting user equipment to send Rate judges the difference of setting of the user equipment for the transmission power of different assemble of symbol.But base station is using blind Detecting Method complexity is higher.
The embodiment of the present invention provides a kind of transmission method of information, determines at least one in instruction subframe by user equipment The transmission power of a set indicates information, and the signaling for carrying transmission power instruction information is sent to base station, so that base It stands and indicates that information determines that at least one of subframe is gathered according to the transmission power, without the function to each symbol in subframe Rate, which carries out blind examination, just can determine that setting of the user equipment to the transmission power of distinct symbols set in subframe, reduce dual link skill The complexity of base station blind Detecting in art.
The symbol mentioned in the embodiment of the present invention refers both to OFDM (the Orthogonal Frequency in LTE system Division Multiplexing, orthogonal frequency division multiplexing) symbol.

After user equipment determines the first symbol in the first subframe, the collection in the first subframe is determined according to first symbol It closes.User equipment determines that the first symbol belongs to first set, alternatively, the first symbol and two symbols adjacent with the first symbol In at least one symbol belong to first set, the symbol in the first subframe before first set belongs to second set, first Symbol in subframe after first set belongs to third set.
Specifically, including 14 symbols in a subframe, if the first sign bit that user equipment determines is the first subframe In the 1st symbol, and in first set only include the 1st symbol when, then user equipment determine in the first subframe from the 2nd A symbol belongs to third set to the symbol between the 14th symbol；If the first sign bit that user equipment determines is the first subframe In last symbol, and in first set only include last symbol when, then user equipment determine in the first subframe In from the 1st symbol to the symbol the 13rd symbol belong to second set；If the first sign bit that user equipment determines is I-th of symbol (2≤i≤13) in first subframe, and in first set only include i-th of symbol when, then user equipment is true Be scheduled in the first subframe from the 1st symbol to the symbol (i-1)-th symbol and belong to second set, from i+1 symbol to Symbol between 14th symbol belongs to third set；If user equipment determines in the first subframe from the 1st symbol to (i-1)-th Symbol between a symbol belongs to second set, belongs to third set from i+1 symbol to the symbol the 14th symbol, And user equipment determines that the power of the symbol in first set is identical as the power of symbol in third set (or second set), Then first set and third set (or second set) are merged into the 4th set by user equipment, i.e. user equipment is determined first Belong to second set from the 1st symbol to the symbol (i-1)-th symbol in subframe, from i-th of symbol to the 14th symbol Between symbol belong to the 4th set and (or belonging to the 4th from the 1st symbol to the symbol i-th of symbol in the first subframe Set, belongs to third set from i+1 symbol to the symbol the 14th symbol).
For including that at least one of the first symbol and two symbols adjacent with the first symbol accord in first set Number when, user equipment determine second set and third set and/or the 4th set principle and first set only include first When symbol, user equipment determines that second set is identical with the principle that third set and/or the 4th are gathered, no longer superfluous here It states.
It is understood that not necessarily due to specific location of first symbol in the first subframe, user equipment is according to this First symbol determines the quantity of the set in the first subframe also not necessarily.If the first symbol is first symbol in the first subframe Or the first last symbol in subframe, then user equipment determines that the quantity of the set in the first subframe is two (the first collection Conjunction and third set, alternatively, first set and second set), alternatively, if user equipment determines the function of the symbol in first set Rate is identical as the power of symbol in third set (or second set), then user equipment by first set and third set (or Second set) merge into the 4th set, i.e., user equipment determine the set in the first subframe quantity be two (third set and 4th set, or, second set and the 4th set)；Alternatively, user equipment determines that the quantity of the set in the first subframe is one (first set, alternatively, all symbols in the first subframe are a set).
Further, user equipment has the power setting of each set more according to the division of the set in the first subframe Kind situation:
There are when three set in (1) first subframe, the power of the symbol of second set and third set can be different Setting, the power setting of the symbol of first set is uncertain, can be identical as the power of the symbol of second set, it is also possible to The power of the symbol of third set is identical；
There are when two set in (2) first subframes, the power of the symbol of first set and second set can be different Setting, alternatively, the power of the symbol of first set and third set may have different settings, no matter but both of these case In it is any, the power of the symbol of first set is less than or equal to the power of the symbol of another set；Alternatively, first set It is identical as the symbol power setting of third set (or second set), therefore the 4th set is merged into, the 4th set and the second collection The symbol power for closing (or third set) can have different settings, and the symbol power of the 4th set is less than or equal to second Gather the power of (or third set)；
There are when a set in (3) first subframes, the power of all symbols in first set is identical, alternatively, first The power of all symbols in subframe is identical；
Wherein, the transmission power of all symbols in each set is identical.
S303, user equipment will carry the transmission power instruction information of at least one of the first subframe of instruction set Signaling is sent to base station.
After user equipment determines the transmission power instruction information of all symbols in the first subframe, user equipment will be carried There is the signaling of transmission power instruction information to be sent to base station, in this way, base station can indicate that information determines according to the transmission power The division of set in first subframe.
Wherein, which includes that at least one in the first subframe gathers the symbol for including.
Illustratively, if collection is combined into first set, second set and third set in the first subframe, which includes the All symbols of one set, alternatively, all symbols of the signaling all symbols comprising second set and third set, alternatively, The signaling includes all symbols of first set, second set and third set.
It should be noted that the first subframe in the embodiment of the present invention is any one height in current timing advance group Frame.User equipment determines that the transmission power instruction information of all symbols in the first subframe can be user equipment in current timing The subframe in group before the first subframe determines in advance, or user equipment determines that the present invention is implemented in the first subframe Example is without limitation.
S304, base station indicate information according to transmission power, determine that at least one of first subframe is gathered.
Corresponding, user equipment will carry the transmission power instruction letter of at least one of the first subframe of instruction set The signaling of breath is sent to base station, and the base station transmission power ready to receive sent to user equipment indicates information.
Specifically, base station refers to after receiving the transmission power instruction information of user equipment transmission according to the transmission power Show information, determine that at least one of first subframe is gathered, that is, determines the dividing condition of the set in the first subframe, in turn, base It stands and the first subframe is demodulated according to the dividing condition of the set in the first subframe.
It should be noted that the transmission power instruction information of user equipment determination and transmission indicates user equipment to base station The transmission power facilities of the current subframe perhaps symbol of the following subframe be user equipment for its current subframe or not Promise to base station is arranged in the transmission power for carrying out the symbol of subframe.For example, user equipment determines transmission power in subframe i (i >=1) It indicates information, and the signaling for carrying transmission power instruction information is sent to base station, and transmission power instruction information refers to Show user equipment in the transmission power facilities of the symbol of subframe i+k (k >=1).Base station indicates information according to the transmission power, Determine the division of the set of the symbol of subframe i+k.In this way, even if user equipment indicates letter in the transmission power that subframe i+k is determined It ceases and indicates that information is different in the transmission power that subframe i is determined from user equipment, user equipment is still according to the hair determined in subframe i Power indicative information is penetrated to be configured the transmission power of the symbol of subframe i+k.
The power of each symbol for the subframe for needing blind examination user equipment to send with base station in the prior art could judge to use Family equipment compares to the setting of the transmission power of assemble of symbol different in subframe, avoids base station and is connect by blind Detecting The power of symbol is received to judge the division of set, reduces the complexity of base station blind Detecting.
Although the prior art can detect the case where transmission power of each symbol by blind Detecting, and the method for the present invention Using user equipment signal base station by the way of, additional signaling overheads may be brought.But base station in the prior art It using blind Detecting, can not judge whether that DMRS (Demodulation can be used there is also base station Reference signal, demodulated reference signal) OCC (Orthogonal Covering Code, orthogonal covering codes) ask Topic.
When the transmission power difference of two reference signal DMRS of mono- subframe of PUSCH, OCC can not be used to DMRS It is orthogonal with the DMRS of other user equipmenies to obtain.OCC is user equipment to be allocated to by base station, and user equipment is upper Row transmission power is that dynamic changes, and depends particularly on the channel overlap with what priority, and the power of the first symbol may be with The symbol of front is identical, it is also possible to identical with subsequent symbol.Base station can not judge user by the result of dynamic blind Detecting Equipment for distinct symbols set power setting situation, to determine the configuration of the OCC of DMRS.Therefore, simultaneously using blind Detecting It is infeasible, need user equipment to report to give base station necessary information, i.e., user equipment sends signaling to base station in the method for the present invention It is necessary.
The embodiment of the present invention provides a kind of transmission method of information, and user equipment determines all symbols in the first subframe Transmission power indicates information, wherein transmission power indicates that information indicates that at least one of first subframe set, set are at least wrapped A symbol is included, and the transmission power of all symbols in a set is identical, then, transmission power instruction information will be carried Signaling be sent to base station so that base station according to transmission power indicate information determine at least one of first subframe gather. With this solution, the transmission power instruction information for indicating at least one of first subframe set is sent to due to user equipment Base station enables base station to directly determine at least one of first subframe set, without to each symbol in the first subframe Number power carry out blind examination just can determine that setting of the user equipment to the transmission power of distinct symbols set in the first subframe, reduction The complexity of base station blind Detecting.

Embodiment 17
The embodiment of the present invention provides a kind of transmission method of information, as shown in figure 22, comprising:
S901, user equipment determine the timing difference information of the first subframe and the second subframe.
Due to CA system be dual link polymerization application scenarios in, user equipment send sub-frame of uplink distinct symbols Gather overlapping from the part for the sub-frame of uplink for belonging to another TAG and different power compressions can have been can be carried out, also, user sets The overlapping region of preparation toward the subframe of the cell of different TAG is greater than the range of a symbol, i.e., the subframe of the cell of different TAG There are certain differences on boundary, and therefore, user equipment determines the timing difference information of the first subframe and the second subframe first.
Wherein, the first subframe and the second subframe belong to different timing advance groups, and the first subframe and the second subframe are determined The time difference is less than preset value.
User equipment determines after determining the timing difference information of the first subframe and the second subframe, according to the timing difference information The first symbol in one subframe.
Specifically, user equipment determine the first subframe in the first symbol it is Chong Die with the second subframe, and the first symbol and The overlapping of third subframe；Alternatively, the border overlay on the boundary of the first symbol and the second subframe, and the boundary of the first symbol and third The border overlay of frame；Second subframe and third subframe are adjacent and belong to identical timing advance group, and belong to not with the first subframe Same timing advance group.
Illustratively, as shown in fig. 7, the boundary of the subframe i of the boundary of the first symbol and TAG2 are heavy in the subframe i of TAG1 It is folded, and in the subframe i of TAG1 the subframe i+1 of the boundary of the first symbol and TAG2 border overlay.
Specifically, including 14 symbols in a subframe, the first sign bit that user equipment determines can be the first son Any one symbol in frame, i.e. the first symbol can be i-th of symbol (1≤i≤14) in the first subframe.
It should be noted that the method that user equipment determines the first symbol in the first subframe, can use any feasible Method, the embodiment of the present invention is without limitation.
Illustratively, according to the timing difference of the first subframe and the second subframe, (timing difference is the side of the first subframe to user equipment The difference on boundary and the boundary of the second subframe, the timing difference are less than or equal to preset value) the first symbol is determined using following formula:
Wherein, PsymbolIt indicates position of first symbol in the first subframe, illustrates that the first symbol is the in the first subframe Several symbols, Ts are chronomere, and nTs indicates that the timing difference of the first subframe of user equipment to report and the second subframe is n Ts,For Ts number of a symbol.
It should be noted that in the present embodiment, when user equipment determines the first symbol using above-mentioned formula, in order to preventCalculated result jumped in character boundary so that user equipment calculate the first symbol position Psymbol The division for the assemble of symbol for changing, and user equipment being caused to be determined according to the first character position changes, with base station root The division for calculating determining assemble of symbol to the timing difference of base station according to user equipment to report before is inconsistent, to cause solution tonality The loss of energy.For this provision, whenWhen close to character boundary, the P that enables user equipment and base station calculatesymbol+ 1, with It prevents user equipment side from unilaterally jumping, and so that the power setting of newly increase superimposed symbols is changed, and not It can be by base station timely learning.
For example, working asWhen,
Otherwise,
User equipment determines that the method for the first symbol is set with user in embodiment three using timing difference in the embodiment of the present invention Standby to determine that the method for the first symbol is different using timing difference, in embodiment three, user equipment is determining the set in the first subframe It divides, when determining first set, has been processed by the above problem, therefore user equipment directly can determine first according to formula Symbol.In the present embodiment, timing difference information is only sent to base station by user equipment, needs regulation user equipment and base station root According to the timing difference, symbol problem is jumped according to identical rule process, to guarantee that user equipment is consistent with base station side behavior.
After user equipment determines the first symbol in the first subframe, the collection in the first subframe is determined according to first symbol It closes.User equipment determines that the first symbol belongs to first set, alternatively, the first symbol and two symbols adjacent with the first symbol In at least one symbol belong to first set, the symbol in the first subframe before first set belongs to second set, first Symbol in subframe after first set belongs to third set.
Specifically, including 14 symbols in a subframe, if the first sign bit that user equipment determines is the first subframe In the 1st symbol, and in first set only include the 1st symbol when, then user equipment determine in the first subframe from the 2nd A symbol belongs to third set to the symbol between the 14th symbol；If the first sign bit that user equipment determines is the first subframe In last symbol, and in first set only include last symbol when, then user equipment determine in the first subframe In from the 1st symbol to the symbol the 13rd symbol belong to second set；If the first sign bit that user equipment determines is I-th of symbol (2≤i≤13) in first subframe, and in first set only include i-th of symbol when, then user equipment is true Be scheduled in the first subframe from the 1st symbol to the symbol (i-1)-th symbol and belong to second set, from i+1 symbol to Symbol between 14th symbol belongs to third set；If user equipment determines in the first subframe from the 1st symbol to (i-1)-th Symbol between a symbol belongs to second set, belongs to third set from i+1 symbol to the symbol the 14th symbol, And user equipment determines that the power of the symbol in first set is identical as the power of symbol in third set (or second set), Then first set and third set (or second set) are merged into the 4th set by user equipment, i.e. user equipment is determined first Belong to second set from the 1st symbol to the symbol (i-1)-th symbol in subframe, from i-th of symbol to the 14th symbol Between symbol belong to the 4th set and (or belonging to the 4th from the 1st symbol to the symbol i-th of symbol in the first subframe Set, belongs to third set from i+1 symbol to the symbol the 14th symbol).
For including that at least one of the first symbol and two symbols adjacent with the first symbol accord in first set Number when, user equipment determine second set and third set and/or the 4th set principle and first set only include first When symbol, user equipment determines that second set is identical with the principle that third set and/or the 4th are gathered, no longer superfluous here It states.
It is understood that not necessarily due to specific location of first symbol in the first subframe, user equipment is according to this First symbol determines the quantity of the set in the first subframe also not necessarily.If the first symbol is first symbol in the first subframe Or the first last symbol in subframe, then user equipment determines that the quantity of the set in the first subframe is two (the first collection Conjunction and third set, alternatively, first set and second set), alternatively, if user equipment determines the function of the symbol in first set Rate is identical as the power of symbol in third set (or second set), then user equipment by first set and third set (or Second set) merge into the 4th set, i.e., user equipment determine the set in the first subframe quantity be two (second set and 4th set, or, third set and the 4th set)；Alternatively, user equipment determines that the quantity of the set in the first subframe is one (first set, alternatively, all symbols in the first subframe are a set).
Further, user equipment has the power setting of each set more according to the division of the set in the first subframe Kind situation:
There are when three set in (1) first subframe, the power of the symbol of second set and third set can be different Setting, the power setting of the symbol of first set is uncertain, can be identical as the power of the symbol of second set, it is also possible to The power of the symbol of third set is identical；
There are when two set in (2) first subframes, the power of the symbol of first set and second set can be different Setting, alternatively, the power of the symbol of first set and third set may have different settings, no matter but both of these case In it is any, the power of the symbol of first set is less than or equal to the power of the symbol of another set；Alternatively, first set It is identical as the symbol power setting of third set (or second set), therefore the 4th set is merged into, the 4th set and the second collection The symbol power for closing (or third set) can have different settings, and the symbol power of the 4th set is less than or equal to second Gather the power of (or third set)；
There are when a set in (3) first subframes, the power of all symbols in first set is identical, alternatively, first The power of all symbols in subframe is identical；
Wherein, the transmission power of all symbols in each set is identical.
The signaling for carrying timing difference information is sent to base station by S902, user equipment.
After the timing difference information that user equipment determines the first subframe and the second subframe, user equipment will carry the timing The signaling of poor information is sent to base station, in this way, base station can determine drawing for the set in the first subframe according to the timing difference information Point.
It should be noted that the first subframe in the embodiment of the present invention is any one height in current timing advance group Frame, the second subframe is the subframe in other timing advance groups, and the timing difference of the first subframe and the second subframe is less than preset value.With Family equipment determines that the timing difference information of the first subframe and the second subframe can be user equipment first in current timing advance group What the subframe before subframe determined, or user equipment determines that the embodiment of the present invention is without limitation in the first subframe.
S903, base station determine the first symbol in the first subframe according to timing difference information, in turn, determine in the first subframe At least one set.
Corresponding, the signaling for carrying timing difference information is sent to base station by user equipment, and base station is ready to receive to use The timing difference information that family equipment is sent.
Specifically, base station is after the timing difference information for receiving user equipment transmission, according to the timing difference information, the is determined The first symbol in one subframe determines the set in the first subframe then, it is determined that at least one of first subframe is gathered Dividing condition, in turn, base station demodulate the first subframe according to the dividing condition of the set in the first subframe.
It should be noted that the timing difference information of user equipment determination and transmission indicates user equipment according to this to base station Timing difference information is that user equipment is current for its in current subframe or the transmission power facilities of the symbol of the following subframe The promise to base station is arranged in the transmission power of the symbol of subframe or the following subframe.For example, user equipment is true in subframe i (i >=1) Determine timing difference information, and the signaling for carrying the timing difference information is sent to base station, and timing difference information instruction user sets The transmission power facilities of the standby symbol for obtaining subframe i+k according to the timing difference information in subframe i+k (k >=1).Base station according to The timing difference information determines the division in the set of the symbol of subframe i+k.In this way, even if what user equipment was determined in subframe i+k Timing difference information is different from the timing difference information that user equipment is determined in subframe i, and user equipment is indicated to still according in subframe i The timing difference information of base station is configured the transmission power of the symbol in subframe i+k.
The power of each symbol for the subframe for needing blind examination user equipment to send with base station in the prior art could judge to use Family equipment compares to the setting of the transmission power of assemble of symbol different in subframe, avoids base station and is connect by blind Detecting The power of symbol is received to judge the division of set, reduces the complexity of base station blind Detecting.
Although the prior art can detect the case where transmission power of each symbol by blind Detecting, and the method for the present invention Using user equipment signal base station by the way of, additional signaling overheads may be brought.But base station in the prior art It using blind Detecting, can not judge whether that DMRS (Demodulation can be used there is also base station Reference signal, demodulated reference signal) OCC (Orthogonal Covering Code, orthogonal covering codes) ask Topic.
When the transmission power difference of two reference signal DMRS of mono- subframe of PUSCH, OCC can not be used to DMRS It is orthogonal with the DMRS of other user equipmenies to obtain.OCC is user equipment to be allocated to by base station, and user equipment is upper Row transmission power is that dynamic changes, and depends particularly on the channel overlap with what priority, and the power of the first symbol may be with The symbol of front is identical, it is also possible to identical with subsequent symbol.Base station can not judge user by the result of dynamic blind Detecting Equipment for distinct symbols set power setting situation, to determine being semi-statically configured for the OCC of DMRS.Therefore, use is blind It detects and infeasible, user equipment to report is needed to give base station necessary information, i.e., user equipment sends signaling in the method for the present invention It is necessary to base station.
The embodiment of the present invention provides a kind of transmission method of information, and user equipment determines determining for the first subframe and the second subframe Time difference information, wherein the first subframe and the second subframe belong to different timing advance groups, and the first subframe and the second subframe are determined The time difference is less than preset value and then the signaling for carrying timing difference information is sent to base station, so that base station is believed according to timing difference It ceases and determines at least one of first subframe set.With this solution, since user equipment is by the first subframe and the second subframe Timing difference information is sent to base station, enables base station to directly determine at least one of first subframe set, without to the The power of each symbol in one subframe, which carries out blind examination, just can determine that user equipment to the hair of distinct symbols set in the first subframe The setting for penetrating power reduces the complexity of base station blind Detecting.
