Description

A kind of terminal determines the method and device of holding phaselocked loop unlatching

Technical field

The present invention relates to pilot technique field, more particularly to a kind of terminal determines the method for keeping phaselocked loop to open and dress It sets.

Background technology

With the development and change of mobile communication business demand, International Telecommunication Union (International Elecommunication Union, ITU) etc. multiple tissues higher user plane both defined to future mobile communication system prolong When performance requirement.One of the main method for shortening user's delay performance is to reduce Transmission Time Interval (Transmission Time Interval, TTI) length, therefore propose short TTI (sTTI) transmission plan.Subframe can be in the transmission plan Multiple sTTI are divided into, such as when the length of sTTI is 2 symbols or 3 symbols, it can be according to side as shown in Figure 1A One subframe is divided into 6 sTTI by formula, is indicated with sTTI index 0-5, wherein first sTTI and the last one sTTI packet Containing 3 symbols, remaining sTTI includes 2 symbols, and a subframe includes altogether 0-13 i.e. 14 symbol, with Synbol index 0-13 is indicated, and a boundary of time slot (Slot boundary) as shown in Figure 1A, indicates that a subframe includes two Slot (time slot).

In sTTI uplink, in order to reduce demodulation reference mark (DeModulation Reference Signal, DMRS) expense, UE can support multiple sTTI on the same symbol in a sTTI by code division multiplexing (Code Division Multiplexing, CDM) and/or frequency division multiplexing (Frequency Division Multiplexing, FDM) Transmit DMRS.The DMRS corresponding to data that one UE is transmitted in a sTTIx may be non-conterminous with the sTTIx It is transmitted on a symbol in sTTIy, if be not present without scheduled in sTTI of the UE between sTTIx and sTTIy Transmission, for UE for power saving, meeting enters discontinuous transmission (Discontinuous in the sTTI between sTTIx and sTTIy Transmission, DTX) state, at this time UE will close radio-frequency devices, this will cause the phase of sTTIx and sTTIy not connect It is continuous, so as to cause the demodulation of the DMRS transmitted in sTTIx the data that cannot be used for transmitting in sTTIy.Radio-frequency devices are closed, mainly It is the phaselocked loop closed in radio-frequency devices, when phaselocked loop (Phase Locked Loop, PLL) is kept it turning on, it is ensured that open The phase for opening frequency source in the period is continuous.

For example, as shown in Figure 1B, when UE1, which is scheduled in, to carry out data transmission in sTTI1 and sTTI3, UE1 is in sTTI1 With each resource block (Resources of the DMRS on first symbol in sTTI1 corresponding to the data transmitted in sTTI3 Block, RB) in second subcarrier (K_TC=1) start to be spaced a subcarrier maps.At this point, since UE1 is in sTTI2 There is no transmission, then in order to economize on electricity, UE1 can close radio-frequency devices in sTTI2 into DTX state, be opened again in sTTI3 Radio-frequency devices are opened to be transmitted, then it is discontinuous to would potentially result in the phase in sTTI1 and sTTI3 for the switching process of radio-frequency devices, It cannot be used for the demodulation of the data of the transmission in sTTI3 so as to cause the DMRS transmitted in sTTI1.

Only carry out data transmission in sTTI2 in another example UE2 is scheduled, corresponding to data transmissions of the UE2 in sTTI2 Each RBs of the DMRS on first symbol of sTTI1 in first subcarrier (K_TC=0) start to be spaced a subcarrier Mapping.At this point, since UE2 has transmission on first symbol only in sTTI1, do not deposited on other symbols in sTTI1 It is transmitting, then in order to economize on electricity, the symbol other than transmitting DMRS that UE2 can be in sTTI1 enters DTX state and closes radio frequency Device, in sTTI2 being again turned on radio-frequency devices is transmitted, then the switching process of radio-frequency devices would potentially result in sTTI1 and Phase in sTTI2 is discontinuous, so as to cause the solution of the DMRS transmitted in sTTI1 the data that cannot be used for transmitting in sTTI2 It adjusts.

In summary, the phase of the corresponding DMRS of data transmission is discontinuous, cannot be used for data so as to cause DMRS Demodulation.But how to ensure the phase continuity of the corresponding DMRS of data transmission, to ensure that DMRS can be used for data solution It adjusts, there is presently no related solutions.

Embodiment 2：

UE can also be according to transmission situation in embodiments of the present invention, it is determined whether keeps phaselocked loop to open, specifically, institute UE is stated according to transmission situation, it is determined whether holding phaselocked loop, which is opened, includes：

UE can be according to transmission situation in embodiments of the present invention, it is determined whether keeps phaselocked loop to open, in the embodiment When UE is determined in time quantum k1 comprising the symbol for being used for transmission DMRS, then one of above method may be used and determine whether to protect Hold phaselocked loop unlatching.DMRS can be only transmitted in time quantum k1, it can also simultaneous transmission DMRS and data.When determining whether When phaselocked loop being kept to open, at the time of can also specifically determining that phaselocked loop is opened, and at the time of closing, and locking phase is being determined When at the time of ring being opened and at the time of closing, can according to where time quantum k1 time slot or subframe determine, can also root It is determined for the timer of preset timing duration according to timing length.

Wherein, a length of first number of symbols symbol or the second quantity slot s lot or third when preset timing Quantity mini-slot mini-slot or the 4th quantity subframe subframe or the 5th quantity time quantum, the 6th quantity A short transmission time interval sTTI, wherein first quantity, the second quantity, third quantity, the 4th quantity, the 5th quantity and Six quantity are the integer not less than 1.

The schematic diagram of terminal transmission data and DMRS as shown in Figure 2 A, as shown in Figure 2 A, a subframe include 2 Slot, each slot include 3 sTTI, and first and the last one sTTI of the subframe includes 3 symbols, remaining sTTI is respectively wrapped Containing 2 symbols.UE1 is according to dispatch or scheduled data pilot structure determination by physically in sTTI1 and sTTI3 The shared channel (Physical UplinkShared Channel, PUSCH) of row or Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) carry out data transmission, the DMRS corresponding to data in sTTI1 and sTTI3 exists It is transmitted on the first symbol in sTTI1.Wherein, in sTTI2 there may be the data transmission of other UE, first in sTTI1 Position resource element (Resource Element, RE) of blank can be used for transmitting the DMRS of data in sTTI2 on symbol.It is right For UE1, DMRS and corresponding data are transmitted in different sTTI, 1 sTTI2 of midfeather.In order to ensure DMRS and corresponding data phase continuity, in embodiments of the present invention UE1 one of following method can be used and determine whether to keep Phaselocked loop is opened：

Method 1：UE1 determines in sTTI1 to include the symbol for being used for transmission DMRS, then UE1 determines the end position in sTTI1 Phaselocked loop is kept to open, until the end position of slot or subframe where sTTI1.Because there is transmission in sTTI1 itself, Phaselocked loop is opened in sTTI1.Where the sTTI1 slot or subframe after, UE1 whether continue keep phaselocked loop unlatching takes Where the scheduling of each sTTI certainly in the latter slot or subframe and transmission situation, specific judgment mode and the sTTI1 Slot or subframe are similar.

Method 2：UE1 determines in sTTI1 to include the symbol for being used for transmission DMRS, then UE1 determines the end position in sTTI1 Or starting position starts timer, in the timing duration of timer, i.e., phaselocked loop unlatching is always maintained at before timing terminates, Include sTTI1 transmission times if the timing duration of timer if starting timer in the starting position of sTTI1, if The end position of sTTI1 starts timer, and the timing duration of timer does not include sTTI1 transmission times then.

For example, a length of 1 slot or 3 sTTI length when timing, then determine if UE1 starts in the starting position of sTTI1 When device, be always maintained in the timing duration of timer phaselocked loop unlatching, i.e., the end position of slot is previous where sTTI1 It is straight that phaselocked loop is kept to open；If end positions of the UE1 in sTTI1 starts timer, timing to the phase in next slot Answer position that phaselocked loop is kept to open, the meter that it is 1 slot which, which meets from the end position of sTTI1 to the position length, Shi Shichang.

Method 3：UE1 determines in sTTI1 to include the symbol for being used for transmission DMRS, then UE1 determines the end position in sTTI1 Or starting position starts timer, when timing a length of 1 subframe or 6 sTTI length, UE1 determine sTTI4 in timing course In include DMRS, then terminate timing in the end position of sTTI3, be always maintained at before terminating timing phaselocked loop open.Terminate After timing, whether also need to that phaselocked loop is kept to open in sTTI4 and in later sTTI, it can be according to above-mentioned sTTI1 Similar mode is judged.

The schematic diagram of terminal transmission data and DMRS as shown in Figure 2 B, as shown in Figure 2 B, a subframe include 2 Slot, each slot include 3 sTTI, and first and the last one sTTI of the subframe includes 3 symbols, remaining sTTI is respectively wrapped Containing 2 symbols.UE1 passes through PUSCH or PUCCH according to dispatch or scheduled data pilot structure determination in sTTI3 Carry out data transmission, the DMRS corresponding to data in sTTI3 is transmitted on the first symbol in sTTI1, and UE1 is in sTTI1 Second and third symbol on there is no transmission, in sTTI2 also be not present transmission, wherein second in sTTI1 and third There may be the data transmission of other UE in a symbol and sTTI2, the positions RE of blank can on first symbol in sTTI1 With for transmitting the DMRS of data in sTTI1 and sTTI2.For UE1, DMRS and corresponding data are in different sTTI Middle transmission, two symbols in 1 sTTI2 and sTTI1 of midfeather, in order to ensure that DMRS and corresponding data phase connect Continue property, UE1 can be used one of following method and determine whether that phaselocked loop is kept to open in embodiments of the present invention：

Method 1：UE1 determines in sTTI1 to include the symbol transmitted for DMRS, then UE1 determines the end position from sTTI1 Or the end position of the symbol for being used for transmission DMRS in sTTI1, the end position to slot or subframe where sTTI1 are kept Phaselocked loop is opened.Where the sTTI1 slot or subframe after, if continue keep phaselocked loop open depend on the latter The scheduling of slot or each sTTI in subframe and transmission situation, specific judgment mode and the slot or subframe where the sTTI1 It is similar.

When UE1, which is determined, keeps phaselocked loop to open since the end position of sTTI1, time quantum can be sTTI grades Not, because sTTI1 itself has transmission on a symbol, then UE1 itself is maintained for phaselocked loop unlatching in sTTI1.

When UE1, which is determined, keeps phaselocked loop to open since the end position of the symbol for being used for transmission DMRS in sTTI1, Time quantum can be symbol rank, because only there is transmission in first symbol in sTTI1, then UE1 itself is accorded at first Necessarily phaselocked loop is kept to open on number.

Method 2：UE1 determines in sTTI1 to include the symbol for being used for transmission DMRS, then UE1 determines the stop bits in sTTI1 Set, or in the starting position of sTTI1, or the symbol for being used for transmission DMRS in sTTI1 end position, or in sTTI1 The symbol for being used for transmission DMRS starting position, start timer, be always maintained at before timing terminates phaselocked loop unlatching.

If starting timer in the starting position of sTTI1, sTTI1 transmission times are included in the timing duration of timer Interior, if the end position in sTTI1 starts timer, sTTI1 transmission times ifs, is not included in the timing duration of timer, Time quantum can be sTTI ranks at this time, be transmitted because sTTI1 itself exists on a symbol, then the UE1 sheets in sTTI1 Body is maintained for phaselocked loop unlatching.

If the starting position of the symbol for being used for transmission DMRS in sTTI1 starts timer, it is used to pass in sTTI1 The transmission time of the symbol of defeated DMRS is included in the timing duration of timer, if being used for transmission DMRS's in sTTI1 The end position of symbol starts timer, and the transmission time of the symbol for being used for transmission DMRS in sTTI1 is not included in timer Timing duration in, time quantum can be symbol rank at this time, because only there is transmission in first symbol in sTTI1, then UE1 itself necessarily keeps phaselocked loop to open on first symbol.

For example, a length of 1 slot or 3 sTTI length when timing, then determine if UE1 starts in the starting position of sTTI1 When device, be always maintained in the timing duration of timer phaselocked loop unlatching, then before slot end positions where sTTI1 always Phaselocked loop is kept to open；If UE1 starts timer in the end position of sTTI1, corresponding in timing to next slot Position keeps phaselocked loop to open, the timing that it is 1 slot which, which meets from the end position of sTTI1 to the position length, Duration.

When UE determines whether that phaselocked loop is kept to open in the above-described embodiments, the symbol for being used for transmission DMRS can be only determined Time quantum, to using the above method come determine whether keep phaselocked loop unlatching.In addition, UE is determining whether to keep locking phase It, can also be single according to the time where being used for transmission the time quantum k2 of data and the DMRS corresponding to the data when ring is opened First k1, to determine whether that phaselocked loop is kept to open.Specifically, the UE is according to transmission situation, it is determined whether phaselocked loop is kept to open Open including：

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 A, UE1 are determined in sTTI3 corresponding to data transmission When DMRS is transmitted in sTTI1, then UE1 is determined keeps phaselocked loop to open between the time interval of sTTI1 to sTTI3, that is, exists It keeps phaselocked loop to open in sTTI2, because itself has transmission in sTTI1 and sTTI3, can inherently be protected in sTTI1 and sTTI3 Hold phaselocked loop unlatching, the state of phaselocked loop then depends on the specific transmission situation of sTTI thereafter after sTTI3, judgment mode and The above process is similar.

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 B, UE1 are determined in sTTI3 corresponding to data transmission When DMRS is transmitted in sTTI1, then UE1 is determined keeps phaselocked loop to open between the time interval of sTTI1 to sTTI3.Specifically , time quantum can be sTTI ranks, because there is transmission in sTTI1 on a symbol, then UE is inherently in sTTI1 Phaselocked loop can be kept to open, therefore keep phaselocked loop to open it is to be understood that only between the time interval of sTTI1 to sTTI3 It needs to keep phaselocked loop to open in sTTI2；Or time quantum can be symbol rank, because of first symbol of sTTI1 Number and sTTI3 in itself exist transmission, UE can inherently be kept in first symbol and sTTI3 of sTTI1 phaselocked loop unlatching, Remaining is not present in the symbol and sTTI of transmission and is closed to save power phaselocked loop, therefore in the time interval of sTTI1 to sTTI3 Between keep phaselocked loop open it is to be understood that need to be in sTTI1 second and third symbol and sTTI2 in keep locking phase Ring is opened.

The state of phaselocked loop then depends on the specific transmission situation of sTTI thereafter after sTTI3, judgment mode with it is above-mentioned Process is similar.

In the above-described embodiments, as long as after time quantum k1 and time quantum k2 is determined, then no matter time quantum k1 and Between time quantum k2 with the presence or absence of transmission, in order to keep Phase Continuation, can time quantum k1 and time quantum k2 it Between keep phaselocked loop open.But actually when in use, there is transmission between possible time quantum k1 and time quantum k2, then UE Phaselocked loop be centainly to maintain unlatching, be continuous if even if not using the control method phase of the embodiment of the present invention at this time. One of therefore in order to achieve the effect that power saving, before the UE determines whether that phaselocked loop is kept to open, with the following method：

When UE judges that there is no transmission or the time quantum k1 between the time quantum k1 and the time quantum k2 The symbol of middle transmission DMRS, there is no when transmission between the time quantum k2, UE determines whether that phaselocked loop is kept to open, tool Any one following method can be used in body：

UE is determined keeps phaselocked loop to open in the time quantum k1 between the time interval of the time quantum k2；Or Time slot where end positions to the time quantum k1 or described time quantums k2 of the UE from the time quantum k1 or subframe End position keep phaselocked loop open；Or UE is from the starting position of the time quantum k1 to the time quantum k1 or described The end position of time slot or subframe where time quantum k2 keeps phaselocked loop to open.

And UE can close radio frequency chip between the time quantum k1 and the time interval of the time quantum k2 The radio-frequency devices such as PA, to achieve the effect that power saving.

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 A, UE1 are determined in sTTI3 corresponding to data transmission When DMRS is transmitted in sTTI1, and judges that UE1 is not present between the time interval of sTTI1 to sTTI3 in i.e. sTTI2 and pass When defeated, then UE1 is determined keeps phaselocked loop to open between the time interval of sTTI1 to sTTI3, i.e., locking phase is kept in sTTI2 Ring is opened, because itself has transmission in sTTI1 and sTTI3, UE1 can inherently keep phaselocked loop to hold in sTTI1 and sTTI3 It opens.The state of phaselocked loop then depends on the specific transmission situation of sTTI thereafter, judgment mode and above process class after sTTI3 Seemingly.

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 B, UE1 are determined in sTTI3 corresponding to data transmission DMRS is transmitted in sTTI1, and UE1 is not present in second of sTTI2 and/or sTTI1 and third symbol when transmitting, then UE1 is determined keeps phaselocked loop to open between the time interval of sTTI1 to sTTI3, specifically, time quantum can be sTTI grades Not, because there is transmission in sTTI1 on a symbol, then UE can inherently keep phaselocked loop to open in sTTI1, therefore Phaselocked loop is kept to open it is to be understood that only needing to keep phaselocked loop in sTTI2 between the time interval of sTTI1 to sTTI3 Unlatching；Or time quantum can be symbol rank, because in first symbol and sTTI3 of sTTI1 there is transmission in itself, UE can inherently be kept in first symbol and sTTI3 of sTTI1 phaselocked loop open, remaining there is no transmission symbol and It is closed in sTTI to save power phaselocked loop, therefore keeps phaselocked loop unlatching can be between the time interval of sTTI1 to sTTI3 It is interpreted as, keeps phaselocked loop to open in second and third symbol and sTTI2 that need to be in sTTI1.

The state of PLL then depends on the specific transmission situation of sTTI thereafter, judgment mode and the above process after sTTI3 It is similar.

Time quantum can be the 7th number of symbols or the 8th quantity mini-slot or in embodiments of the present invention Nine quantity sTTI or the tenth quantity time slot or the 11st quantity subframe, wherein the 7th quantity, the 8th quantity, 9th quantity, the tenth quantity and the 11st quantity are the integer not less than 1.

Embodiment 3：

In order to realize that flexible configuration, UE, can also matching according to configuration signal when determining whether that phaselocked loop is kept to start It sets to determine, specifically, configurations of the UE according to configuration signal, it is determined whether holding phaselocked loop, which is opened, includes：

Wherein the configuration signal is sent to UE for network side equipment, such as can be that eNB is sent.

Specifically, the UE receives configuration signal, determined whether that phaselocked loop is kept to open according to the instruction of the configuration signal It opens one of with the following method：

UE according to the instruction of the high-level signaling determine whether keep phaselocked loop open when, the specific can be that, network Side apparatus (eNB) can judge the transmission situation of the UE in advance, and high-level signaling is sent to the UE, and whether UE is configured by high-level signaling Phaselocked loop is kept to open, when UE receives the high-level signaling, if high-level signaling instruction UE keeps phaselocked loop to open, UE Phaselocked loop is kept to open, UE closes phaselocked loop if UE receives high-level signaling instruction, and UE closes phaselocked loop.

Wherein, the high-level signaling can be wireless heterogeneous networks (Radio Resource Control, RRC) signaling, It may be media access control (Media Access Control, MAC CE) signaling.

For example, the schematic diagram of terminal transmission data and DMRS as shown in fig. 2 a or 2b, UE1 receives high-level signaling, according to The instruction of high-level signaling determines whether that phaselocked loop is kept to open.Specifically, eNB prejudge UE1 can be carried out similar Fig. 2A or The scheduling of Fig. 2 B, then first pass through whether high-level signaling configuration UE1 keeps phaselocked loop to open in advance, when UE receives the high-level signaling When, if high-level signaling instruction UE keeps phaselocked loop to open, UE1 keeps phaselocked loop to open, if UE receives high-rise letter Instruction UE is enabled to close phaselocked loop, then UE closes phaselocked loop.

UE is according to configuration signal, it is determined whether when phaselocked loop being kept to open, can also be according to the downlink control received Instructions field in channel processed determines whether that phaselocked loop is kept to open.

Instructions field wherein in down control channel can also be always effectively only effective under given conditions.When When instructions field can be always effective, then UE needs always to obtain the instruction content of instructions field, i.e. UE is needed in down control channel The instruction content of instructions field is obtained in scheduled each time quantum；When instructions field is effective under given conditions, UE is only needed The instruction content of instructions field is obtained under given conditions, such as can be the time quantum worked as scheduled in the down control channel In comprising be used for transmission DMRS symbol when it is effective, then at this time UE need obtain instructions field instruction content.

The down control channel be using upstream and downstream control information (Downlink control information, DCI) down control channel of format or the down control channel using downlink DCI format.

The down control channel is for dispatching at least one time quantum.

The instructions field of down control channel not only can indicate whether UE keeps phaselocked loop to open in embodiments of the present invention, The time span that UE keeps phaselocked loop to open is also can indicate that in the instructions field, wherein when there is also fingers in down control channel Show that the time span that domain instruction UE keeps phaselocked loop to open, the instructions field according in the down control channel determine whether Holding phaselocked loop, which is opened, includes：

For example, the schematic diagram of terminal transmission data and DMRS as shown in fig. 2 a or 2b, UE1 is controlled according to the downlink to be believed The instructions field in road determines the time span for keeping phaselocked loop to open, and keeps phaselocked loop to open according to the time span.

If there is no instructions field instruction UE to keep the time span that phaselocked loop is opened in the instructions field of down control channel, Then the UE receives down control channel, is determined whether that phaselocked loop is kept to open according to the instructions field in the down control channel Including：

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 A, UE1 according to the instruction in the down control channel, Determining from the end position of sTTI1 keeps phaselocked loop to open, corresponding to the new down control channel that receives Whether sTTIy starts to keep phaselocked loop unlatching that can be determined according to the down control channel corresponding to the sTTIy in the sTTIy.

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 B, UE1 according to the instruction in the down control channel, Determining from the end position of sTTI1 keeps phaselocked loop to open, or from the end position of the symbol for being used for transmission DMRS in sTTI1 It keeps phaselocked loop to open, until the sTTIy corresponding to the new down control channel that receives, starts whether to protect in the sTTIy Phaselocked loop unlatching is held, can be determined according to the down control channel corresponding to the sTTIy.

In the above-described embodiments, time quantum can be sTTI ranks, be kept when UE1 is determined from the end position of sTTI1 When phaselocked loop is opened, because sTTI1 itself has transmission on a symbol, then UE1 can inherently keep locking phase in sTTI1 Ring is opened.

Time quantum can also be symbol rank, when UE1 determines the end from the symbol for being used for transmission DMRS in sTTI1 When position keeps phaselocked loop to open, transmitted because only existing in first symbol in sTTI1, then UE1 itself on first symbol Phaselocked loop will be kept to open.

If there is no instructions field instruction UE to keep the time span that phaselocked loop is opened in the instructions field of down control channel, Then the UE receives down control channel, is determined whether that phaselocked loop is kept to open according to the instructions field in the down control channel Can also include：

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 A, UE1 determinations are since the end position of sTTI1, directly End position to slot or subframe where sTTI1 keeps phaselocked loop to open.Because there is transmission in sTTI1 itself, Phaselocked loop is opened in sTTI1.Where the sTTI1 slot or subframe after, UE1 whether continue keep phaselocked loop unlatching depends on Where the scheduling of each sTTI in the latter slot or subframe and transmission situation, specific judgment mode and the sTTI1 Slot or subframe are similar.

The schematic diagram of terminal transmission data and DMRS as shown in Figure 2 B, UE1 determine from the end position of sTTI1 or The end position of the symbol for being used for transmission DMRS in sTTI1 keeps phaselocked loop to open, until the slot or subframe where sTTI1 End position.Where the sTTI1 slot or subframe after, if continue keep phaselocked loop open depend on the latter The scheduling of each sTTI in slot and transmission situation, specific judgment mode with where the sTTI1 slot or subframe it is similar.

When UE1, which is determined, keeps phaselocked loop to open since the end position in sTTI1, time quantum can be sTTI grades Not, because sTTI1 itself has transmission on a symbol, then UE1 itself is maintained for phaselocked loop unlatching in sTTI1.

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 A, UE1 are true according to the corresponding down control channels of sTTI3 Determine the DMRS in sTTI3 corresponding to data transmission to transmit in sTTI1, then UE1 determines the time interval in sTTI1 to sTTI3 Between keep phaselocked loop open, i.e., in sTTI2 keep phaselocked loop open because in sTTI1 and sTTI3 itself exist transmission, UE1 can inherently keep phaselocked loop to open in sTTI1 and sTTI3, and the state of phaselocked loop then depends on thereafter after sTTI3 The specific transmission situation of sTTI, judgment mode are similar with the above process.

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 B, UE1 are true according to the corresponding down control channels of sTTI3 Determine the DMRS in sTTI3 corresponding to data transmission to transmit in sTTI1, then UE1 determines the time interval in sTTI1 to sTTI3 Between keep phaselocked loop open.Specifically, time quantum can be sTTI ranks, because existing on a symbol in sTTI1 Transmission, then UE can inherently keep phaselocked loop to open in sTTI1, therefore be kept between the time interval of sTTI1 to sTTI3 Phaselocked loop is opened it is to be understood that only needing to keep phaselocked loop to open in sTTI2；Or time quantum can be symbol level Not, because in first symbol and sTTI3 of sTTI1 itself exist transmission, UE inherently can sTTI1 first symbol and Phaselocked loop is kept to open in sTTI3, remaining is not present in the symbol and sTTI of transmission and is closed to save power phaselocked loop, therefore Phaselocked loop is kept to open second and third it is to be understood that need to be in sTTI1 between the time interval of sTTI1 to sTTI3 Phaselocked loop is kept to open in symbol and sTTI2.

The schematic diagram of UE transmission datas and DMRS as shown in Figure 2 A, UE sTTI1 end position start timer or Starting position starts timer, and in the timing duration of timer, phaselocked loop unlatching is always maintained at before timing terminates, if Start timer in the starting position of sTTI1, the timing duration of timer includes then sTTI1 transmission times, if sTTI1's End position starts timer, and the timing duration of timer does not include sTTI1 transmission times then.

For example, a length of 1 slot or 3 sTTI length when timing, then determine if UE1 starts in the starting position of sTTI1 When device, be always maintained in the timing duration of timer phaselocked loop unlatching, then before slot end positions where sTTI1 always Phaselocked loop is kept to open, it is corresponding in timing to next slot if UE1 starts timer in the end position of sTTI1 Position keeps phaselocked loop to open, the timing that it is 1 slot which, which meets from the end position of sTTI1 to the position length, Duration.

Or UE1 is determined and is started timer in the end position of sTTI1 or starting position, when timing a length of 1 subframe or 6 STTI length, UE1 determine in sTTI4 to include DMRS, then terminate timing in the end position of sTTI3, tying in timing course Phaselocked loop unlatching is always maintained at before beam timing.After terminating timing, whether also needed in sTTI4 and in later sTTI It keeps phaselocked loop to open, can be judged according to above-mentioned sTTI1 similar modes.

The schematic diagram of terminal transmission data and DMRS as shown in Figure 2 B, UE sTTI1 end position, or in sTTI1 Starting position, or the symbol for being used for transmission DMRS in sTTI1 end position, or being used for transmission in sTTI1 The starting position of the symbol of DMRS, starts timer, and being always maintained at phaselocked loop before timing terminates opens.

Or, UE1 determines a length of 1 subframe or 6 in the end position of sTTI1 or starting position startup timer, timing A sTTI length, UE1 determine in sTTI4 to include DMRS, then terminate timing in the end position of sTTI3 in timing course, Terminate to be always maintained at phaselocked loop unlatching before timing；After terminating timing, whether also needed in sTTI4 and in later sTTI It keeps phaselocked loop to open, can be judged according to above-mentioned sTTI1 similar modes
