Specific embodiment

The disclosure being described below to help comprehensive understanding to be defined by the claims and their equivalents for referring to attached drawing is provided Various embodiments.It includes various details to help to understand, but these are considered only as illustratively.Therefore, this field Skilled artisan will realize that in the case where not departing from the scope of the present disclosure and spirit, it can be to described herein various Embodiment makes various changes and modifications.In addition, for clarity and conciseness, it is convenient to omit the description to known function and structure.

The term and word used in the following description and claims is not limited to dictionary meanings, but is only made by inventor With enabling to clear and consistently understand the disclosure.Therefore, it will be apparent to one skilled in the art that mentioning Be for illustration purposes only for being described below for various embodiments of the disclosure, rather than for limiting by appended claims and its The purpose for the disclosure that equivalent limits.

It should be understood that unless the context clearly determines otherwise, otherwise singular " one ", "one" and "the" include plural number Indicant.Thus, for example, including the reference to surface as one or more to the reference of " assembly surface ".

By the embodiment being below with reference to the accompanying drawings described in detail, the advantages of the disclosure and feature and the mode for realizing them It will become obvious.However, the disclosure can be embodied in many different forms, and should not be construed as being limited to herein The embodiment of elaboration.On the contrary, thesing embodiments are provided so that the disclosure is detailed and complete, and will be the model of the disclosure It encloses and is fully conveyed to those skilled in the art.The disclosure is limited solely by the scope of the following claims.It is identical in the entire disclosure Appended drawing reference refers to identical element.

In the new radio (NR) currently just discussed in third generation partner program (3GPP), in addition to being drilled for a long time Into except connection mode defined in (LTE) and idle mode, the introducing of an inactive mode is also determined.The spy of an inactive mode Seeking peace, it is as follows to require.

Radio access network (RAN) and signaling and resource use in core network (CN) should be minimized.

The required time that data are transmitted under an inactive mode should be minimized.Here it is possible to be maintained at user equipment (UE) An inactive mode or be in connection mode while execute data transmission.

It should support the paging by RAN and the existing paging of the CN by LTE.

Define the notification area (hereinafter, the region RAN) based on RAN.In the region RAN, UE is in not location updating In the case of move.G node B (gNB) in the region RAN maintains access layer (access stratum, AS) context of UE.

According to above-mentioned requirements, an inactive mode UE be should be able to execute for rapid data transmission/received operation.Operation First is that cell reselection.Substantially, such as in above-mentioned requirements, an inactive mode UE is moved without position more in the region RAN Newly.However, if an inactive mode UE executes cell reselection by operation identical with the idle mode UE in existing LTE, Then in view of rapid data transmission/reception, this may be inappropriate.

Fig. 1 is to show the UE according to an embodiment of the present disclosure after being transformed into an inactive mode to move in the region RAN The case where figure.

With reference to Fig. 1, the environment of the disclosure is shown.This environment shown in Fig. 1 or in the case of, RAN notification area by Multiple gNB are formed, these gNB are classified as have Cell Radio Network Temporary Identity effective for an inactive mode UE symbol (C-RNTI) the gNB 110 and gNB 120 without effective C-RNTI.An inactive mode UE is free in RAN notification area It is mobile.

In the case of figure 1, have been coupled to the gNB 110 with C-RNTI UE be transformed into from connection mode it is inactive Then mode moves freely in the region RAN.

In Fig. 1, the gNB 110 that service is finally provided to UE determines according to an inactive mode for the AS context for maintaining UE Justice is come the C-RNTI that maintains UE to use.Therefore, if an inactive mode UE sends data to gNB 110 and receives from gNB 110 Data need not then reconfigure C-RNTI.

On the other hand, even if gNB 120 belongs to the region RAN of UE, gNB 120 does not have the C- of an inactive mode UE yet RNTI.Therefore, as an inactive mode UE with gNB 120 rather than when the gNB 110 of the C-RNTI with UE is communicated, when in RAN When moving in region, gNB 120 needs to distribute the process of C-RNTI to UE.This can increase the data transmission of an inactive mode UE With received delay.

In 3 gpp, discussing that the data transmission/received independent radio net for an inactive mode UE is interim The introducing of identifier (RNTI).In the disclosure, this is referred to as region RNTI (A-RNTI).A-RNTI is designed to allow The identifier that all UE in the region RAN are a uniquely assigned.Because the region RAN includes multiple cells, A-RNTI have than The C-RNTI that the UE being designed to allow in cell is a uniquely assigned bigger expense.

Following Fig. 2 to Fig. 5, which is shown, according to an embodiment of the present disclosure receives DL data from gNB in the region RAN The operation of an inactive mode UE.

Fig. 2 is to show the gNB according to an embodiment of the present disclosure from effective C-RNTI to receive downlink (DL) number According to an inactive mode UE operation figure.

With reference to Fig. 2, because there is gNB C-RNTI, gNB can send number by using C-RNTI in operation S210 According to.

Fig. 3 to Fig. 5 is to show the gNB according to an embodiment of the present disclosure for not maintaining C-RNTI from the region RAN to receive DL The figure of the operation of an inactive mode UE of data.

It shows with reference to Fig. 3, Fig. 3 in operation S310, belongs to all gNB in the region RAN by using A-RNTI for DL number According to being sent to an inactive mode UE.Because UE is in most cases actually adjacent with a gNB, in the region RAN It is the inefficient utilization to resource that all gNB, which send DL data by using unique A-RNTI,.

Fig. 4 and Fig. 5 be show it is according to an embodiment of the present disclosure by executing 2 steps or 4 step random access channel (RACH) It identifies adjacent gNB and receives the figure of the operation of an inactive mode UE of DL data from adjacent gNB.

Firstly, being sought in operation S410 or S510, all gNB for belonging to the region RAN by using the A-RNTI of UE to execute It exhales.Then, 2 steps or 4 step RACH are executed in response to the UE of paging, and via RACH message 1 (S420) or RACH message 3 (S520) it includes A-RNTI in paging signal that notice gNB:UE, which corresponds to,.Receive the message gNB recognize it is inactive Near mode UE is located at, and send DL data.The operation leads to expense, because all gNB in the region RAN send paging letter Number.In addition, other expenses occur during UE has to carry out 2 steps or 4 step RACH are operated.

Referring to figs. 2 to Fig. 5, when gNB has effective C-RNTI, data transmission/reception of an inactive mode UE has most Small delay and the signaling for needing least UE and gNB.Therefore, an inactive mode UE is rested on for a long time as far as possible It imitates and is advantageous around the gNB of C-RNTI.This aspect should be reflected in the cell reselection operation of an inactive mode UE.The disclosure Propose the cell selection behaviour that a kind of permission an inactive mode UE is rested on as long as possible around the gNB with effective C-RNTI Make.

Firstly, the cell reselection operation that the UE in LTE will be described.In LTE, the cell reselection of idle mode UE is referred to By UE selection persistent district, system information is obtained, maintenance synchronizes and receives the operation of paging signal.In order to understand cell reselection Operation, it is necessary to understand cell selection operation.Cell selection includes measuring and inducing (inducing) following Srxlev and check Whether Srxlev is greater than zero operation (details is identical as LTE standard, therefore thereof will be omitted).Here, Srxlev by Qrxlevmeas, Qrxlevmin, Qrxlevminoffset and Pcompensation composition.Qrxlevmeas is surveyed corresponding to UE Reference Signal Received Power (RSRP) value of amount, and others Qrxlevmin, Qrxlevminoffset and Pcompensation is the parameter that gNB is notified by system information, radio resource control (RRC) message etc. to UE.

[table 1]

Based on the concept of above-mentioned suitable cell, i.e. Srxlev > 0, cell reselection is executed by following operation in LTE. Firstly, UE measures the signal strength of current persistent district (i.e. serving cell) and neighboring community, Rs and Rn is then exported.Here, Qmeas, s and Qmeas, n respectively indicate the signal strength (RSRP) of serving cell and neighboring community.In addition, Qhyst, s and Qoffset, n are that gNB is supplied to UE to prevent the parameter of frequent cell reselection.After the signal strength of measurement cell, UE exists Selection has the cell of highest Rs or Rn in cell of the Srxlev greater than zero, then the executive resident in selected cell.Such as The current persistent district of fruit and the cell newly selected are different from each other, then this means that UE executes cell reselection.

[table 2]

Above description is the cell reselection process of the idle mode UE in LTE.Meanwhile it is contemplated that is newly introduced in NR is non- In activity pattern, in view of rapid data transmission/reception of an inactive mode UE, UE is rested on for a long time as far as possible to be had effectively It is advantageous in the cell of C-RNTI.It sends/connects in consideration of it, proposing and being suitable for the rapid data of an inactive mode UE The cell reselection operation of receipts.In the disclosure, term " cell " can be used interchangeably with base station, gNB or e node B (eNB), be owned These all have the same meaning.

The present disclosure proposes a kind of method, for by cell reselection to gNB application additional offset but regardless of some Cell is serving cell or neighboring community, to allow an inactive mode UE most in the gNB with C-RNTI effective to UE It may stop for a long time.

Fig. 6 is the figure for showing the residence reselecting of an inactive mode UE according to an embodiment of the present disclosure.

With reference to Fig. 6, for having the gNB 610 of effective C-RNTI for an inactive mode UE, UE is in cell reselection Addition additional offset QC-RNTI is simultaneously applied to ranking cells.On the other hand, for not having for an inactive mode UE's The gNB 620 of effective C-RNTI, UE execute ranking cells without additional offset.

Basic cell reselection operation is same as described above.In the case where gNB has effective C-RNTI of an inactive mode UE, As shown in fig. 6, UE can apply additional offset (herein referred as QC-RNTI).According to the disclosure, for not having for inactive The gNB of effective C-RNTI of mode UE, UE do not apply additional offset (QC-RNTI).Such as according to the cell reselection equation of the disclosure Under.

[table 3]

Alternatively, as follows according to the cell reselection equation of the disclosure.

[table 4]

An inactive mode UE executes cell reselection according to above-mentioned equation in as shown in Figure 7 to 9 following three kinds Operation.

Fig. 7 be show it is according to an embodiment of the present disclosure mobile from the gNB with effective C-RNTI in an inactive mode UE To without effective C-RNTI gNB in the case where cell reselection operation figure.

With reference to Fig. 7, it is assumed that UE is currently resident on the gNB 710 with effective C-RNTI.According to the disclosure, in view of quick Data transmission/reception, UE are retained in current service cell (that is, gNB 710 with effective C-RNTI) for a long time as far as possible In be advantageous.Therefore, when exporting the Rs of current service cell in the sequencer procedure for cell reselection, in addition to Qmeas, Except s and Qhyst, s, UE also adds QC-RNTI, s.

However, UE is not applied and is removed because the gNB 720 that UE is being moved to does not have effective C-RNTI for UE Qmeas, n and Qoffset, any additional offset except n.In the example, an inactive mode UE export in this way Rs and Rn, and they are compared to execute final cell reselection.

[table 5]

Fig. 8 be show it is according to an embodiment of the present disclosure an inactive mode UE from without effective C-RNTI gNB move Move the figure of the cell reselection operation in the case where the gNB with effective C-RNTI.

With reference to Fig. 8, it is assumed that UE is currently resident on the gNB 820 of no effective C-RNTI.According to the disclosure, in view of quick Data transmission/reception, UE be retained in for a long time in neighboring community the gNB 810 of effective C-RNTI (that is, with) as far as possible and It is not to be advantageous in current service cell (that is, the gNB 820 for not having effective C-RNTI).Therefore, when for cell When exporting the Rs of current service cell in the sequencer procedure of gravity treatment, UE is not applied except Qmeas, s and Qhyst, any attached except s Biasing is moved.

However, because the gNB 810 that is being moved to of UE does not have effective C-RNTI for UE, in addition to Qmeas, N and Qoffset, s, except n, UE also adds QC-RNTI, n.In the example, an inactive mode UE export in this way Rs and Rn, and they are compared to execute final cell reselection.

[table 6]

Fig. 9 be show it is according to an embodiment of the present disclosure an inactive mode UE from without effective C-RNTI gNB move Move the figure of the cell reselection operation in the case where another gNB without effective C-RNTI.

With reference to Fig. 9, it is assumed that UE is currently resident on the gNB 920 without effective C-RNTI.When with C-RNTI's When executing cell reselection between gNB and gNB without C-RNTI, the disclosure generates the effect different from conventional method.Therefore, In the case where Fig. 9, cell reselection operation is similar to traditional operation.That is, when for the collated of cell reselection When exporting the Rs of current service cell in journey, UE is not applied except Qmeas, s and Qhyst, any additional offset except s.In addition, When exporting the Rn of neighboring community, UE is not applied except Qmeas, n and Qhyst, any additional offset except n.It is non-in the example Activity pattern UE exports Rs and Rn in this way, and they are compared to execute final cell reselection.

In LTE system, in order to support broadband, have been incorporated into for handling multiple component carrier (component together Carrier, CC) such as carrier wave polymerization (carrier aggregation, CA) and dual link (dual connectivity, DC multi-carrier scheme).In the case where 20MHz CC, the polymerization up to 32 CC can support the bandwidth of 640MHz.However, such as Fruit supports the ultra wide band (for example, 1GHz) in the new radio of 5G (NR) system using the scheme of such as LTE CA, then terminal is wanted The combined quantity of the CC used is exponentially increased, and the size of the capability report executed by terminal also increases.Therefore, eventually End is had no option, can only the only operation in limited CC is combined.In addition, the quantity with CC in CA increases, the reception of terminal is multiple The control complexity of miscellaneous degree and base station also increases.However, although CA or DC there are such problems, CA or DC use resource Aspect has greater flexibility than single carrier wave.This is because auxiliary (SCell) addition/release allows to change extending bandwidth, And it is cross-carrier to dispatch the resource transmission/reception for allowing to dispatch other CC.

In addition, 5G system defines high-effect operation, main target is the power efficiency by terminal and base station network [bit/J] improves more than 1000 times.For this reason, it is necessary to the size of the operational frequency bands of controlling terminal, to solve to be drawn by broadband transmission A possibility that extra power consumption risen, this is essential for the operation of SHF band (mmW).

The present disclosure proposes the operation schemes of terminal and base station, for realizing 3GPP RAN 5G system information (system Information, SI) in the efficiency Key Performance Indicator (key performance indicator, KPI) that is just discussing.Specifically Ground, this disclosure relates to which the layer 1/2 of terminal and base station in mobile communication system operates.More specifically, this disclosure relates to a kind of use The power consumption of terminal is reduced in the operational frequency bands of the change terminal when base station expectation carries out ultra-broadband signal transmission/reception with terminal Method and apparatus.

The present disclosure proposes a kind of ultra wide band transmission/received sides of controlling and setting in 5G mobile communication system Method.Specifically, consider the method for scheduling, transfer and power saving in ultra wide band.In 5G mobile communication system, it is desirable that supporting Such as enhanced mobile broadband (enhanced mobile broadband, eMBB), super reliable and low latency communicate (ultra Reliable and low latency communication, URLLC) and enhanced machine type communication (enhanced Machine type communication, eMTC) various services (or fragment (slice)).This can with as the 4th Generation (4G) mobile communication system LTE in support voice over internet protocol (voice over Internet protocol, VoIP) and in the identical context of (best effort, BE) service of doing one's best understand.In addition, it is expected that in 5G mobile communication system Various numerologies (numerology) will be supported in system.Especially because the difference of subcarrier spacing or Transmission Time Interval (TTI) It is different.Therefore, it is desirable to support the TTI of various length in 5G mobile communication system.With the LTE phase for only supporting a kind of TTI (1ms) Than this is one of the notable feature of 5G mobile communication system.If 5G mobile communication system supports the 1ms TTI than LTE to be so short that More TTI (for example, 0.1ms), then it is expected that this needs the URLLC of short delaing time to support is very big help.In the disclosure, Numerology is used as and the terms with identical meanings such as subcarrier spacing, subframe lengths, symbol/sequence length.Moreover, terminal Different bandwidth (BW) can be configured in different numerology regions.Base station be also referred to as such as gNB, eNB, NB and The various terms of BS.Terminal is also referred to as the various terms of such as UE, MS and STA.

Figure 48 is the figure for showing the scalable BW system of LTE according to an embodiment of the present disclosure.

Figure 49 is the figure for showing the feature of the flexible BW system of 5G NR according to an embodiment of the present disclosure.

With reference to Figure 48, in order to support various BW, LTE to have been incorporated into the concept of scalable BW.According to Figure 48, LTE system Support the terminal with the identical various BW (for example, 5/10/20MHz) of centre frequency.For example, if the first UE 4810 is supported 5MHz and the 2nd UE 4820 support 10MHz, then LTE base station properly configures control channel and sends control signal, so that two A UE can receive control signal.However, when total available bandwidth when base station is very big, i.e., in ultra wide band, this method pole The earth limits the resource that the terminal with relatively small frequency band can be used.For example, when the 3rd UE 4830 operation is available in base station When the edge of frequency band, which may not distinctively receive the control signal of base station.

With reference to Figure 49, in 5G NR communication system, it should operational frequency bands can be configured flexibly.That is, passing through It obtains configured access BW 4900 according to synchronous signal receiver and SI to be successfully established after RRC connects, terminal can be in base station Control under that operational frequency bands (or operation BW) from relatively narrow frequency band (or narrow BW) 4910 are switched to relatively wide frequency band is (or wide BW)4920.Using wide frequency band, terminal can receive the control signal of base station to help to improve control signal performance, or Data transmission/reception (DL or UL) can be executed to improve resource efficiency.

Moreover, terminal should be able to send and receive important control signal in 5G NR communication system, even if so as to The connection with base station can be also maintained in some frequency band that existing scalable BW system is not supported.In the case where LTE, by means of Signaling radio bearer (signaling radio bearer, SRB) sends such important control signal via PCell.This Outside, it in PCell, sends and receives for the scheduling and hybrid automatic repeat-request (HARQ) mistake in PCell and SCell itself The control signal of journey.In LTE, each of PCell or SCell can be an independent cell.For each cell, Need individual MAC entity and corresponding link circuit self-adapting and HARQ entity.However, in 5G NR carrier wave communication system, it is whole A frequency band corresponds to a cell.It is connect in addition, should substantially provide for terminal access, connection foundation/maintenance and data are sent/ The function of the PCell of receipts.

Meanwhile even if base station operation is in ultra wide band, due to limited embodiment and complexity, terminal also only can be whole Transmission/reception is executed in a part of a frequency band.In order to make terminal in the frequency band for being greater than maximum available bandwidth (that is, the BW allowed) Middle operation, it is necessary to operate in a time division manner.In order to be easier to manage, ultra wide band can be divided into suitable size by base station Frequency band or subband (sub-band), and instruction terminal performed various functions in special frequency band (for example, control signal send/ Reception, data-signal transmission/reception, RS, measurement, scheduling, link circuit self-adapting, Modulation and Coding Scheme (MCS), HARQ etc.).And And terminal can judge based on frequency band and receive the structure of control channel and reference signal.

Figure 50 is the various frequency band splitting schemes shown in the flexible BW system of 5G NR according to an embodiment of the present disclosure Figure.

With reference to Figure 50, in situation A, since fixed frequency band configures, UE1 5000 only can be in a part of available band Rather than it is operated in entire available band.

In situation B, UE2 5010 may be not supported in frequency band 4, be matched because maximum available bandwidth is less than by base station The bandwidth 5011 for the frequency band 4 set.

If minimizing bands unit as shown in situation C, the UE 5020 with various bandwidth can be supported, because of UE Frequency band to be used is indicated by a branch of small frequency band.But too many frequency band may result in expense increase.

Therefore, as in situation D, it is useful for freely configuring the scheme of frequency band size.

In order to solve the above problems when entire frequency band is divided into the frequency band of terminal by base station, the present disclosure contemplates a kind of sides Case, wherein base station is that each terminal configures different size of frequency band, and frequency band can be expressed as with same size by system Subband combination.Moreover, not being to execute independent scheduling, link circuit self-adapting, MCS and HARQ in the subband that divides in view of system Process, but a scheduling, link circuit self-adapting, MCS and HARQ procedure will be executed in the frequency band configured in view of terminal.

The structure of physical layer control channel should be designed to scalable for one or more subbands in a frequency band.This meaning Can support with can by the multiple of the subband at least frequency band indicate frequency band terminal.Frequency band as a branch of subband Size by between terminal and base station channel characteristics, numerology, control subband size and minimum packet size at least one A determination.Terminal is directed to one MAC function collection (scheduling, MCS, HARQ etc.) of a service execution.

The function that the system structure that can be proposed by the disclosure provides can be considered as follows.

[control of every frequency band/RS/CSI report/HARQ feedback configuration]

When configuring frequency band, base station can by indicate basic unit (RB or sub-band) multiple come to terminal notification frequency The range (that is, beginning, size or centre frequency and bandwidth) of band.Because the location and range of frequency band are network systems at it A part of one carrier wave of middle operation, so base station can frequency shift (FS) by the centre frequency of entire carrier frequency band and band Width to configure frequency band to terminal.Alternatively, base station can pass through the centre frequency where synchronization signal that terminal detects Frequency shift (FS) and bandwidth to configure frequency band to terminal.Meanwhile the centre frequency of carrier frequency band that terminal is learned can be always The centre frequency for the synchronization signal that terminal detects, can be connected to the synchronization signal detected as terminal SI indicated by The center frequency information of carrier wave is identical, or the centre frequency letter for the carrier wave that base station indicates in establishment process can be connect with RRC Manner of breathing is same.Frequency range is interpreted as band system band by terminal.Therefore, even if being assigned with the frequency band of different range, terminal should also be set It counts into and signal is received according to identical reception rule.

For example, beginning and the size of the frequency band of terminal configuration should be based upon to determine the reference signal sent by base station (RS) or the position of control channel.In addition, should be based upon terminal configuration frequency band beginning and size sent out to determine by terminal The position of the CSI report or HARQ feedback sent.Meanwhile when configuring multiple frequency bands, base station can also be to be directed to for terminal configuration Multiple frequency bands share HARQ procedure and are still directed to each band separation HARQ procedure.

The frequency band for being configured to terminal monitors is referred to as main band (primary band, p frequency band).Terminal can not removed Monitoring is executed in resource area except p frequency band, unless there are any and p band separation control/configurations.

It can selectively be operated auxiliary frequency band (secondary band, s frequency band) according to by the configuration of p frequency band, and p Frequency band and s frequency band can be known respectively as the first radio frequency (RF) frequency band and the 2nd RF frequency band.Furthermore, it is possible to by RRC information or P frequency band is activated to active state from the frequency band candidate that at least one or more is configured by MAC CE or DCI.Furthermore, it is possible to logical It crosses RRC information or MAC CE or DCI and s frequency band is activated to active state from the frequency band candidate that at least one or more is configured. Similarly, base station can deactivate one by sending deactivated signal or message to terminal via RRC information or MAC CE or DCI Or multiple frequency bands make it from active state to inactive state.In the disclosure, active band is used as similar contain with p frequency band Justice, but p frequency band needs the combination of DL frequency band and UL frequency band in configuration.Therefore, p frequency band is active band, but all activities Frequency band is not always p frequency band.In addition, p frequency band is not deactivated, in addition to individual frequency band handoff procedure.In time division duplex (TDD) In the case of, the frequency location of DL frequency band and UL frequency band can be identical in p frequency band.

P band configurations include at least one DL frequency band and one or more UL frequency band, and base station can be matched with instruction terminal Set p frequency band.When terminal includes the UE capability report of RF information to base station report, base station can match for each of terminal difference RF Set p frequency band.

Hereinafter, behaviour associated with the frequency band switching in single or multiple active bands/activation instruction will be described Make.

Terminal can monitor the frequency band of one or more configurations simultaneously according to RF condition.Therefore, have in terms of scalability Benefit, the frequency band of base station indicate jointly to be applied to terminal under the conditions of different RF.However, base station is needed through terminal Other RF conditions of terminal are known in advance in capability report.Otherwise, sharp from frequency band #1 to frequency band #2 when being issued for some terminal When instruction living, a possibility that there are faulty operations because can not can know that frequency band #1 whether due to terminal RF limitation and stopped With.

When the terminal operated in single-unit activity frequency band receives frequency band activation instruction from base station, terminal is switched to instruction Frequency band and deactivate previous frequency band.When the terminal operated in multiple active bands receives frequency band activation instruction from base station When, terminal activates the frequency band of instruction and maintains the use of the frequency band.

However, being possible to faulty operation occur by the band configurations that the capability report of terminal carries out.Therefore, base station should It is capable of the maximum quantity of the active band of configurating terminal and explicitly indicates that deactivating for frequency band.

Activation/disabling operation rule for frequency band can be pre-configured with according to one of following two method, or can be with By base station/network configuration.In addition, the operation can also be equally applicable to other than the activation instruction of the independent frequency band of base station Frequency band switching/activation and across frequency band scheduling instruction together there is a situation where.

Although a) being configured with multiple active bands, each active band is only switched into other and deactivates frequency band.Therefore, only It can change the quantity of active band with RRC.

B) multiple active bands are configured with, and make activation/deactivated instruction for each frequency band.Because can change movable frequency The quantity of band, so base station should be operated so as to be no more than the maximum quantity of the active band of terminal and deactivate all frequencies Band.If base station instruction is more than maximum activity frequency band, terminal can operation be initial 1) to deactivate in active band previous The frequency band of activation, 2) frequency band minimum by the sequence of band index deactivate the frequency band finally activated, 3) is deactivated, 4) matched according to base station The priority for the frequency band set deactivates lowest band or 5) deactivates some frequency band arbitrarily determined by terminal.Moreover, deactivated frequency Band, which can be configured as, excludes p frequency band.

Hereinafter, description is used to determine to include resetting (retuning) when activating frequency band by DCI or MAC CE The process of the transfer point of delay.

The RF readjustment time can change according to the relationship between switch of frequency band and the active band switching condition of terminal.Base Standing can be configured to terminal by RRC a frequency band (for example, p frequency band) being switched to another frequency based on the capability report of terminal With the required time.If terminal does not meet the configuration, terminal can refuse the frequency band switching of each frequency band.

Base station by DCI indicate frequency band switching in the case where, 1) terminal can be considered from by RRC configure Switching delay time when DCI receiving time (subframe/time slot/small time slot) is completed to switching.Therefore, terminal can be based on DCI In include frequency band mark (ID), in the frequency band activated after the switching delay time that Cong Cong DCI receiving time starts most Fast effectively control channel monitors control channel.Alternatively, 2) can include in DCI from DCI receiving time (subframe/time slot/ Mini time slot) to switching complete when switching delay time k and frequency band ID.Therefore, terminal can be according to the determination of the value of k Control channel is monitored from most fast effectively control channel after time.

In the case where base station indicates frequency band switching by MAC CE, 1) terminal can be based on the frequency band for including in MAC CE ID, by the switching time for considering to have configured by RRC, from from for the MAC CE received HARQ ACK success time Most fast effectively control in the frequency band activated after switching delay time when (subframe/time slot/mini time slot) is completed to switching Channel monitoring control channel.Alternatively, 2) the switching delay time configured by RRC can be considered in terminal.Terminal can With determined based on frequency band ID, the Cong Cong MAC for including in MAC CE frequency band switching and to PHY send instruction time (subframe/when Gap/mini time slot) it is monitored to the most fast effectively control channel in the frequency band of activation after switching delay time when switching completion Control channel.It alternatively, 3) can include that successfully time (when subframe/time slot/mini is received from MAC CE in MAC CE Gap) to switching complete when switching delay time k and frequency band ID.Therefore, terminal can be from when receiving successfully from MAC CE Between most fast effectively control in the frequency band that activates after the switching delay time of (subframe/time slot/mini time slot) when being completed to switching Channel monitoring control channel processed.It alternatively, 4) can include receiving successful HARQ from for MAC CE in MAC CE Switching delay time k and frequency band ID when the transmission time (subframe/time slot/mini time slot) of ACK is completed to switching.Therefore, Terminal can be from from the transmission time (subframe/time slot/mini time slot) of successful HARQ ACK be received for MAC CE to cutting Change the most fast effectively control channel monitoring control channel in the frequency band activated after switching delay time when completion.Terminal follows At least one of aforesaid operations.

[from frequency band/across frequency band scheduling]

Figure 51 be show it is according to an embodiment of the present disclosure from frequency band/across frequency band scheduling operation figure.

With reference to Figure 51, by the control subband 5110,5130 and 5150 in p frequency band, base station can be dispatched in same sub-band Data channel 5120, the control channel 5160 in data channel 5140 or other subbands in other subbands.

Base station can be controlled by the control subband in the p frequency band configured for each terminal is believed by the control of terminal Transmission/reception of the signal of road or data channel.Base station can be by referring to from frequency band data dispatch or across frequency band data dispatch Show downlink (DL) or uplink (UL) data transmission/receiving area.Moreover, base station can be dispatched by controlling from frequency band To indicate the position of the control subband in same frequency band or the change of size.Moreover, base station can be dispatched by across frequency band control To indicate position or the size of the additional control sub-band in other frequency bands.

If the position or size, terminal by first control subband instruction the second control subband check whether while supervising Depending on the first control subband and the second control subband.If it is, terminal can receive signal by two control subbands simultaneously.It is no Then, it means that terminal only monitors the first control subband.Therefore, it in order to monitor the second control subband, needs for a certain amount of The delay that RF is resetted.

In general, UL scheduling in the case where, base station can by control the scheduled length of delay of subband instruction terminal (for example, 4ms) or individual length of delay.

In the system that the disclosure is considered, wherein may require bandwidth change across frequency band scheduling, even if DL dispatch In the case where, it is also desirable to the individually specific sub-frame followed by instruction in time, and be used under data transmission/received physics Ink Shared Channel (PDSCH) is normally indicated in subframe identical with PDCCH.

This is because when the position sudden change of used frequency band, need for resetting RF and base band (BB) circuit Handle the time.That is, it is contemplated that terminal capability report in include available band information and caused by the control of base station Terminal service band variation degree, base station answer instruction terminal after the transmission of control signal delay time for configuring it After send and receive DL signal.Delay time may include in each control signal or base station can be in the ability of terminal Negotiate and is pre-configured at least one delay time value during connecting establishment process.Because postponing complete in the service band of terminal Than partly overlapping in the service band of terminal and only bandwidth changes in the case that is bigger in the case where change, so base station passes through Each control signal sends delay time or sends the index of two or more length of delays by controlling signal, so that terminal can Operation is received to execute DL after an appropriate delay.

Meanwhile base station can execute terminal in DL and UL with the asymmetric p frequency band of different frequency bands (position, size) Configuration.However, because major control function is smoothly operated in p frequency band when supporting both DL and UL, even if distribution P frequency band is also interpreted as one by different frequency bands, terminal.

[adaptive BW method and power saving program]

LTE system provides battery saving mode (PSM) and discontinuous receive (DRX) to reduce power consumption.PSM refer to only executing with Track area update (tracking area update, TAU) or routing region updating (routing area update, RAU) are simultaneously And the state of paging is not received from base station.This is nearly similar to power off, but terminal is not needed to be re-attached to network or be built again Vertical packet data network (packet datanetwork, PDN) connection, because it is still registered in a network.

DRX points are idle mode DRX and connection mode DRX.According to idle mode DRX (that is, free time-DRX), idle mode UE does not receive the signal of base station, in addition to the period (paging frame number and paging occasion) for periodically monitoring paging signal. In this case, it is connect because terminal does not have with the RRC of network, network does not have the contextual information of terminal.Terminal It is considered as being registered in mobility management entity (mobility management entity, MME) and resides in tracking area In domain list (tracking area list, TAL).Connection mode DRX the purpose is to reduce work as each DL of connection mode terminal Subframe monitors caused power consumption when control signal (PDCCH) of base station.If terminal arbitrarily skips the monitoring of DL subframe, base station It is difficult to controlling terminal as needed.Therefore, base station and terminal should be executed in the DL subframe in predetermined position base station transmission and The reception of terminal.

The DRX operation of LTE connection is as follows.Base station can establish request message or the request of RRC connection reconstruction by RRC connection Message configures the DRX relevant parameter in RRC parameter.DRX relevant parameter includes that such as DRX recycles (cycle), unlatching continues Time timer (on-duration timer) and inactivity timer (inactivity timer).The instruction of DRX circulation is eventually End repeats the length of the single duration of ON and OFF, and opens the length that the duration is opened in duration timer instruction Degree.Duration timer can be recycled and opened from DRX calculate the length for closing the duration.These parameters are single with subframe Position indicates.The DL on PDCCH that terminal monitors base station during what is indicated by unlatching duration timer opens the duration Signal, and not in the DL signal closed on the PDCCH for monitoring base station in the duration.If terminal success in some subframe DL signal is received, then inactivity timer is since the subframe.Terminal should monitor the DL signal on the PDCCH of base station, directly Until inactivity timer expires.After last time is properly received DL signal, if reached and inactivity timer The corresponding subframe of expiration time and the subframe, which belong to, closes the duration, then terminal does not monitor DL signal.

Specifically, it depends on DRX to recycle, C-DRX can be classified as short DRX and long DRX.According to the activity of DL signal, Terminal is always switched to short DRX in each subframe, then switches to long DRX, and switch again at the end of long DRX circulation The state operated to no DRX.In order to configure the operation, the repetition time of short DRX circulation is indicated using short DRX cycle timer Number.In the case where long DRX, terminal is switched to sleep state after DRX one long circulation.Base station can pass through MAC order Element (command element, CE) indicates the beginning of short DRX or long DRX, so that terminal switches back into short DRX or maintains long DRX State.Exceptionally, in the DL HARQ packet retransmissions present for being defined as HARQ two-way time (round trip time, RTT), eventually End should monitor DL signal but regardless of DRX.In addition, if expectation UL HARQ packet retransmissions present, then terminal should be configured as DRX Monitoring DL controls signal, i.e. UL authorization in the duration of retransmission timer.

According to LTE, short DRX is expressed as follows:

[(SFN*10)+subframe numbers] modulo (shortDRX-Cycle)=(drxStartOffset) modulo (shortDRX-Cycle)

According to LTE, long DRX is expressed as follows:

[(SFN*10)+subframe numbers] modulo (longDRX-Cycle)=drxStartOffset

When LTE connection mode DRX (C-DRX) is applied to 5G NR, similar equation can be used.

If LTE C-DRX is applied to 5G NR, the terminal for receiving high-speed data service will be supervised opening in the duration Depending on the broadband DL signal of base station, and it will not be in close and monitor DL signal in the duration.However, the spy for the business of depending on Property, it is not necessary to every subframe receives broadband DL signal.For example, in the case where flowing service, using in periodical large capacity information In only send the encoding scheme of image change information.Therefore, in 5G NR communication system, it should adaptively change by terminal The size of the bandwidth (BW) of the resource of monitoring.

Figure 52 to Figure 54 be show according to various embodiments of the present disclosure by physical layer control signal carry out BW extension With the exemplary figure of reduction operation.

If executing the variable BW control in L1 layers (i.e. physical layers), the operation as shown in Figure 52 to Figure 55 is can Can.In order to save power, it is reasonable that terminal, which lies substantially in narrow BW state, and if it is required, then is switched to wide BW.

With reference to Figure 52, therefore, terminal monitors in RRC connection establishment step controls subband by the narrowband that L1 is provided (control sub-band, CSB) (CSB#1) 5210, and if receiving the L1 signal 5230 that instruction BW extends from base station, Then monitor that broadband controls subband (CSB#2) 5220 in specific sub-frame.

Determined according at least one of the following receive BW extended instruction control signal time point with go to Interval between the subframe of the switching of CSB#2: a) fixed intervals, b) by the interval of RRC parameter configuration, c) matched by L1 control signal The interval set, d) according to the BW ability information of terminal report and the computable interval of present terminal state and e) to be switched Whether the centre frequency of BW is overlapped.

On the other hand, when terminal continuously requests a large number of services, should frequently send BW extended instruction control signal, and In the worst case, due to the limitation of switching delay, the half of subframe can be serviced in narrowband.In addition, frequent BW and RF Switching may cause terminal load and additional power consumption.

With reference to Figure 53, shows and further use BW diminution instruction control letter when BW extended instruction control signal is used only Number come the example that solves the problems, such as.

According to the operation, terminal monitors CBS#1 5310 switches band when receiving BW extended instruction control signal 5330 It is wide to monitor CSB#2 5320, and maintain the mode.Then, when by CSB#2 5340 receive BW reduce instruction control signal When 5360, terminal switches bandwidth to monitor CSB#1 5350.However, if failing to receive BW extension or reducing instruction control letter Number, then this method may cause the mistake in terminal operation.

For example, although base station sends BW extended instruction control signal 5330 and is sent by the CSB#2 5320 of instruction subframe For data transmission/received control signal (DCI), but terminal is likely not to have received BW extended instruction control signal 5330.Due to monitoring CSB#1, terminal does not receive the DCI sent by CSB#2 5320.In this case, even if terminal It is successfully received BW extension instruction control signal 5330 or terminal fails to receive BW extension instruction control signal 5330, base It stands and does not also know whether terminal fails to receive the DCI sent by CSB#2 5320.

Moreover, if terminal fails to receive DL letter within a certain period of time due to monitoring the mismatch of frequency band (i.e. CSB) Number, then terminal may be operative to DRX closing or cause problem in HARQ timeline.

It is operated according to shown in Figure 54 and Figure 55, L1 letter can be reduced by reducing instruction control signal without using BW Number receive mistake problem.That is, terminal can be only during the specific duration after BW extension in broadband (CSB# 2) operation, then returnes to narrowband (CSB#1) in.

With reference to Figure 54, base station controls signal 5430 by BW extended instruction also in CBS#1 5410 and is used for terminal notification Monitor the duration 5440 of the position CSB#2 and CSB#2 5420.

On the other hand, it is contemplated that the capacity and performance of L1 signal, base station can be by RRC parameter rather than L1 signals come pre- It is first configured to maintain the Duration Information in broadband.However, compared with the case where using L1 signal, first pass through in advance RRC into Dynamic control can be limited in the case where row configuration.Therefore, when using RRC parameter, timer may be it is useful, it is such as existing DRX inactivity timer, rather than fixed duration.

Figure 55 to Figure 58 be show according to various embodiments of the present disclosure by physical layer and radio resource control (RRC) control signal carries out the exemplary figure of BW extension and reduction operation.

With reference to Figure 55, the CSB#2 that terminal monitors are indicated by the BW extended instruction control signal 5530 in CBS#1 5510, so Afterwards due to failing to start the timer 5540 that RRC is configured from next 5520 subframe of CSB#2 reception DL signal.If timer It is expired without after 3 subframes and receives DL signal, then terminal returns to the narrowband CSB#1 in next subframe.It can change Become the starting time of timer.

If timer value be set to it is small, even if the control signal of base station is actually sent to terminal, terminal May due to channel quality deterioration and base station signal cannot be continuously received.In this case, it may occur however that frequency band mismatch, Middle base station sends signal in broadband, and terminal attempts to receive signal in narrowband.It base station can be from the feedback or tune for working as terminal Start timer when the UL signal of degree does not reach or when the event for not having UL signal to reach meets specified criteria.When base station When timer expires, base station sends base station signal by narrowband control channel (i.e. CSB#1).It, can be pre- in order to support the operation First determine the position of the unlatching duration of the narrowband control channel of terminal.That is, the beginning of the operation in broadband can be with Control channel depending on L1/MAC signal, and in narrowband is received the DRX for operating and can following and being determined based on system time and followed Ring, such as traditional DRX are operated.When broadband inactivity timer expires according to the inactive of the control channel in broadband, eventually It resets to narrowband and duration reception control channel is opened according to the DRX of configuration in end.

On the other hand, according to circumstances, inactive explanation can differently be applied.

With reference to Figure 56, terminal extends instruction control signal 5620 in response to BW and is switched to broadband 5610, then in next son The BW that base station is received in frame reduces instruction control signal 5630.This is because base station has determined that there is no sent by broadband Business.

Even if terminal monitors narrowband CSB#1, the inactivity timer 5650 that RRC can also be maintained to configure is without expiring. That is, in the state that terminal does not receive DL resource allocation control signal in broadband (i.e. CSB#2), in response to base station Control signal or some terminal operation for switching between broadband and narrowband of rule can influence inactivity timer.Terminal can Only to stop timer after receiving DL resource allocation control signal by the CSB#2 in broadband.

It is a kind of operation with reference to shown in Figure 57, wherein after the starting of timer 5710, when the BW in terminal switches the phase Between when being successfully received base station signal by broadband CSB#2 5730 timer expire, and when not received in subsequent subframe Second timer 5720 starts when to DL signal.

With reference to Figure 58, in order to avoid the complex operations as shown in Figure 56 and Figure 57, according to embodiment, base station can be in terminal Broadband switching after pass through the mode 5810 that switches between broadband and narrowband of RRC configuration.Such as in other embodiments, base station Signal 5820 can be controlled by L1 or RRC signal designation terminal carries out the first narrowband switching.When being controlled with RRC, it should base Position is determined in SFN (system frame number, System Frame Number) and subframe.If BW switching is not urgent, can use MAC command element (CE) replaces L1 and controls signal.In this case, MAC CE should include absolute location information rather than phase To interval information.

BW switching mode can be configured as the absolute position relative to SFN and subframe, or be configured as relative to Utilize the position of the specified position of L1 control signal.In addition, the effective subframe of mode can be limited to open duration phase with DRX Corresponding subframe or DRX cycle timer expire before subframe.In addition, base station can be switched by MAC CE with instruction terminal To which BW.

When base station is using physical layer signal or RRC control signal designation BW handover operation, for dynamic setting, pass through L1 Control signal is configured can be configured prior to controlling signal by RRC.However, it is contemplated that believing since multiple L1 are controlled Number and be difficult to the case where carrying out stable terminal operation, in the subframe with predetermined position (period deviates) pass through RRC control Signal is configured always before controlling signal by L1 and being configured.

Meanwhile independently of the BW control operation carried out by physical layer signal, the C-DRX of LTE can be modified, that is, is connected DRX operation, with associated with BW control.Can be individually operated using the method for C-DRX, or can with pass through physical layer signal The operation of control BW operates together.Detail is described below with reference to Figure 59.

Figure 59 and Figure 60 is the connection mode DRX (C- for adaptive BW shown according to various embodiments of the present disclosure DRX) the exemplary figure operated.

It is configured according to LTE DRX, a DRX circulation, which is divided into, opens the duration and close the duration.Similarly, With reference to Figure 59, a DRX circulation can be divided into broadband and open duration 5910, narrowband unlatching duration 5920 by base station With the closing duration 5930.For the program, base station only needs the attached of each frequency band into terminal notification DRX configuration information The unlatching Duration Information added.However, then terminal may need considerably long if there is the various frequency band sizes being gradually reduced Time can just be transformed into completely closed state.

With reference to Figure 60, according to another embodiment, terminal can operate in the specific DRX circulation of frequency band, wherein for supervising It can be configured differently in time depending on the duration of broadband and narrowband.It is similarly to certain when being needed in short DRX circulation The operation being switched to when the circulation of quantity in the LTE C-DRX of long DRX circulation.Therefore, base station can be according to the frequency band to be switched (DRX circulation, unlatching duration, DRX cycle timer etc.) 6010 to 6060 configuration informations, and frequency band are recycled according to DRX Switching law may include in C-DRX configuration.For example, this can with the sequence of frequency band #1, frequency band #2, frequency band #3 etc. or The sequence of CSB#1, CSB#2, CSB#3 etc. indicates.

Alternatively, according to embodiment, the sequence of frequency band switching can entrust to physical layer completely.In this case, Terminal is controlled signal according to L1 and is determined BW and CSB with public DRX circulation and the operation of DRX cycle timer.Terminal can be Inquiry will change into the BW of L1 before one DRX cycle timer expires.

Alternatively, in RRC connection foundation or RRC connection reestablishment procedure, terminal can request L1 that multiple BW are arranged (CSB) and its sequentially.At the end of a DRX cycle timer expires or DRX is recycled, terminal switches BW (CSB) according to sequence. If terminal reconfigures control signal according to the BW of base station or extends BW, BW again according to condition preconfigured in terminal (CSB) switch in order from the BW of extension again.When the DRX circulation of the minimum BW (CSB) after all BW (CSB) have switched Or DRX cycle timer, when expiring, terminal a) is switched to long DRX, while keeping minimum BW (CSB), b) by switch to independent The BW (CSB) of the long DRX of configuration is switched to long DRX or c) it is switched to idle DRX.

On the other hand, in the case where not introducing new C-DRX configuration, can maintain existing LTE C-DRX configuration and Operation, and be arranged using additional L1 to control BW and change operation.According to embodiment, the C-DRX configuration to be controlled by RRC is phase With, but base station can be configured to by using L1 signal open the duration in carry out BW switching information (BW, SRB, number of sub frames etc.).According to another embodiment, base station can be configured by using L1 signal is encountering short DRX circulation every time When just reduce, for BW switching information (BW, SRB etc.).According to yet another embodiment, base station can be come by using L1 signal Configuration is connected to the BW of short DRX circulation and is connected to the BW of long DRX circulation.

The different parameters for having for BW in a DRX configuration are assumed in the operation of the modification of C-DRX.On the one hand, BW Different DRX configurations are possibly used for more free DRX configuration.In this case, terminal should check multiple DRX in the same time It is operated while configuration, and it is necessary to determine which DRX configuration has priority according to pre-defined rule, to prevent mixing The operation confused according to multiple DRX configuration.

Figure 61 is to show the exemplary figure according to an embodiment of the present disclosure for the DRX of broadband and narrowband setting.

With reference to Figure 61, thus it is shown that the shape of broadband DRX 6110 and 6115 and narrowband DRX 6120 and 6125 is respectively configured State.Terminal receives the DRX configuration of two frequency bands, and must comply with one in two DRX configurations for clashing behaviour The subframe of work.If emphasizing power consumption, terminal may prefer to narrowband DRX configuration rather than broadband DRX is configured.

Figure 62 and Figure 63 is to show DRX setting according to various embodiments of the present disclosure and for the preferential of broadband and narrowband The exemplary figure of grade rule.

With reference to Figure 62, a kind of operation is shown, wherein opening 6210 He of duration when being configured with broadband in a subframe When both duration 6220 are opened in narrowband, terminal follows narrowband and opens duration configuration 6210 and by configuring narrowband CSB# 1 monitors DL signal.

With reference to Figure 63, on the other hand, in the prior situation of volume of transmitted data, Figure 63 shows a kind of operation, wherein When being configured with the broadband unlatching duration 6310 in a subframe and both duration 6320 are opened in narrowband, terminal is followed It opens duration configuration 6310 and monitors DL signal by switch to broadband CSB#2 in broadband.In order to support such as Figure 62 and figure The configuration of difference shown in 63, base station can also configure the precedence information between the DRX of frequency band by RRC to terminal.

If being not received by DL signal in for each frequency band and the DRX of its operation configuration, terminal starts not Active time.If being provided with the inactivity timer of each frequency band, terminal a) can be somebody's turn to do being not received by correspond to When the DL signal of frequency band, starts the inactivity timer of corresponding frequency band or b) frequency band can be corresponded to being not received by DL signal when, start the inactivity timer of each frequency band.

If being single value regardless of frequency band will be inactive timer setting, can will be used to determine that DRX is inactive Condition be determined as at least one of the following: 1) only when be not received by all frequency bands (CSB of all configurations) DL letter Number when start inactivity timer or 2) only when frequency band (CSB) that is not received by with according to priority selects corresponding DL signal Shi Qidong inactivity timer.

In the disclosure, about DRX operate and the type for the DL signal to be monitored in a standard determine or can be by base It stands configuration.The DL signal that should not be monitored is operated about DRX if received, it may be considered that being not received by DRX operation DL signal.

The BW proposed in the disclosure is adaptively and during power saving, it is also necessary to will be configured to the one or more of scheduling Frequency band configuration associated with DRX process.

According to the various embodiments of proposition, thus it is possible to vary allocation plan associated with DRX process.Each embodiment is main It is classified as follows, and the configuration of DRX procedure correlation can change according to this classification.

A. the L1/MAC signal of base station is depended on from the timing that frequency band 1 is switched to frequency band 2 in terminal, and is cut from frequency band 2 Change to the timing of frequency band 1 also in compliance with base station L1/MAC signal in the case where:

Because frequency band ID is included in L1/MAC signal, configured with individual DRX not related.That is no matter How is frequency band, and DRX can be operated jointly.However, base station can be with when the reception mistake of L1/MAC signal of base station occurs It is configured to the special frequency band (for example, frequency band 1) of rollback (fallback) operation.At this point, base station can include in DRX configuration Rollback frequency band.

B. the L1/MAC signal of base station is depended on from the timing that frequency band 1 is switched to frequency band 2 in terminal, and is cut from frequency band 2 Change to frequency band 1 timing follow inactivity timer in the case where:

When terminal is switched to frequency band 2 from frequency band 1, configuration frequency band 2 associated with DRX is not needed.However, working as from frequency band 2 when being switched to frequency band 1, and DRX is configured to operate in frequency band 1 by base station, because it follows timer.Be switched to frequency band 2 it Terminal should follow the inactivity timer of frequency band 2 afterwards, and can be configured to be operated according to one of the following by base station: 1) be used in conjunction with the inactivity timer of DRX, 2) using being inactivity timer that frequency band 2 is separately configured, 3) using having contracting Put the inactivity timer of the DRX of value or 4) using the inactivity timer with scale value being separately configured for frequency band 1.Contracting Putting value can be by DRX configuration or individual configuration instruction.

C. from frequency band 1 to frequency band 2 switching depend on base station L1/MAC signal (but control channel receive timing be Be separately configured), and the switching from frequency band 2 to frequency band 1 also depend on base station L1/MAC signal (but control channel receive Timing is separately configured) in the case where:

In this case, the DRX circulation of band sharing should be configured and open the DRX circulation of duration or each frequency band With the unlatching duration.In the case where band sharing, individual band configurations are not needed for DRX configuration.If it is each Band configurations DRX then executes configuration at least one of by the following method: 1) by the quantity Matching of DRX configuration and frequency band And indicate the frequency band in each DRX configuration, and 2) one DRX of setting configure and indicates to include holding in DRX configuration for unlatching The continuous time and close the duration operation frequency band, 3) one DRX of setting configure and indicate DRX configure in include short DRX Circulation and long DRX circulation each of frequency band or 4) be arranged a DRX configure and indicate include DRX configure in For opening the frequency band of each of duration, short DRX circulation and long DRX circulation.

In setting proposed by the present invention and in the process, the layer 2 of terminal may not be needed to know the physical location of frequency band and big It is small.That is, the physical message of frequency band is invisible at layer 2, but logical place and size can be set.Layer 2 can be with base Control channel or transmission channel are constructed in logic frequency band location/size information.It is operated in addition, terminal can be managed for DRX List in BW information and according to index display it.

In the example proposed in the disclosure, it has been assumed that most of terminals cannot monitor narrowband and broadband BW simultaneously.But It is that, according to the ability of terminal, can monitor narrowband and broadband BW simultaneously in some cases.

Meanwhile it the BW that is provided by L1 signal and can be different according to the maximum BW of the terminal of terminal capability.Therefore, When receiving multiple BW specific DRX configuration, terminal can be specific in one or more BW in the maximum BW of terminal capability DRX configuration the unlatching duration in operate simultaneously.The DRX configuration of the maximum BW more than terminal capability is excluded from monitoring Open the duration.For the operation, the priority of the specific DRX configuration of BW can be allocated to terminal by base station.

Figure 64 is the flow chart for showing the operation of terminal according to an embodiment of the present disclosure.

With reference to Figure 64, during RRC connection establishment process S6410, terminal is in operation S6420 and S6430 request and from object Manage the information for the position that layer is obtained about operation BW or control subband (CSB).

In operation S6440, based on acquired information, or by reporting acquired information to base station, terminal from Base station receives the DRX configuration or the configuration of the parameter for every BW in DRX of every BW.

When connecting completion, terminal starts the operation for short DRX in C-DRX.In operation S6450, terminal is to each Subframe executes PDCCH monitoring to receive the control signal of base station.Then, in operation S6460, terminal determines that the reception of DL signal is No success.

If the reception success of DL signal, terminal are consecutively carried out PDCCH monitoring.Under certain conditions, it is understood that there may be Such situation: although successfully having carried out PDCCH monitoring, L1 control or RRC control under monitored another BW or CSB。

If the result as PDCCH monitoring does not receive DL signal, terminal updates DRX parameter in operation S6465, all Such as inactivity timer and DRX cycle timer.If due to meeting inactivity timer or BW switching timing in operation 6470 The condition of device and need to carry out BW switching, then terminal operation S6475 check whether it meets short DRX termination condition.Condition example Such as correspond to the case where PDCCH monitoring fails at minimum BW and the BW further reduced is therefore not present or short DRX is followed The case where ring timer expires.

If being unsatisfactory for short DRX termination condition in operation 6470, terminal reduces BW in operation S6480 and restarts Short DRX operation.

If meeting short DRX termination condition, terminal starts long DRX in operation S6485.Long DRX operation is with minimum or matches The BW set is executed, and is generally similar to LTE long DRX operation.In operation S6490, terminal monitors PDCCH according to long DRX.If It is unsuccessfully received DL signal in operation S6491, then terminal determines whether to meet long DRX termination condition in operation S6492.If Meet long DRX termination condition, then in operation S6493, terminal is switched to idle mode.

For the method for determining the inactive condition in wide BWP to be separately provided:

The BW of the disclosure is adaptive or handover operation is different from SCell addition/release in existing CA, as described below.? In CA, PCell is activated always, and terminal monitors PCell.However, in the case where BW switching, even if in any frequency band Mobile, terminal should also be sent to base station and the control signal from base station reception such as RRC signal and MAC CE.Therefore, even if Terminal is switched to another frequency band (frequency band 2) from a frequency band (frequency band 1) and does not have data service in frequency band 2, and terminal can also Signal is controlled to receive the RRC/MAC of base station.However, the RRC/MAC for receiving base station in the frequency band 2 as narrowband controls signal It will affect the power consumption of terminal.Therefore, when determining inactive in frequency band 2, terminal can be operated by the following: 1) not The control channel activity of the RRC/MAC for being used to only send base station control signal is reflected in inactivity timer operation, 2) only The dispatching distribution that will be less than some Physical Resource Block (PRB) is reflected in non-active timer operation, and 3) when in a certain continue In when receiving base station signal (or a certain amount of transmission) of a certain number, be reflected in inactivity timer operation, 4) only Specific DCI format is reflected in inactivity timer operation or 5) by the independent instruction of base station and determines whether to reflect In inactivity timer operation.

Dual timer setting:

The above description is that the timer operations for being switched to narrowband from broadband.Being switched to broadband from narrowband can be by base The DCI/MAC signal designation stood.However, terminal should be switched to from broadband when mistake occurs when receiving DCI/MAC signal Narrowband is to retract.However, base station can be arranged differently than timer value, because the requirement of two kinds of situations may be different.? That is terminal starts timer # when receiving the DCI/MAC signal for being switched to broadband from narrowband during monitoring 1.If terminal does not also receive base station letter until timer #1 expires while executing frequency band handover operation in broadband Number, then terminal returns to narrowband.

On the other hand, success receives base station signal in broadband and is then not received by after the unlatching duration terminates The terminal of base station signal starts timer #2.When timer #2 expires, terminal is switched to narrowband.Generally, it is advantageous to timing The value of device #1 is shorter than the value of timer #2, because of fast fallback in case of mistakes.

Figure 65 shows the DRX operation according to an embodiment of the present disclosure changed for TTI.

With reference to Figure 65, the time needed for transmission time interval (TTI) refers to the one or more transmission blocks (TB) of transmission, and It is typically used as the Elementary Time Unit for executing scheduling and HARQ operation in MAC.Terminal is preparatory in initial access process TTI information is received, or default TTI and BW information is received by SI.

For example, basic TTI can be set by the normal TTI that length is 1ms.In addition, during random access procedure or After completion is established in RRC connection, terminal can receive additional TTI and BW information by RRC information.For example, can will be attached TTI is added to be set as the short TTI that length is 0.5ms.

For expressing the parameter of DRX operation in LTE to indicate as unit of subframe.With reference to the normal TTI situation of Figure 65 6510, it can be seen that the unlatching duration is indicated that DRX circulation is indicated by 6ms by 2ms.

When DRX parameter expression scheme identical with LTE is imported directly 5G, TTI is arranged to short TTI, such as short TTI feelings Shown in condition A 6520, and terminal monitors PDCCH during the unlatching duration that identical DRX recycles the 2ms in (6ms).Though So in normal TTI, the number of PDCCH monitoring is twice, but in short TTI feelings in same unlatching duration (2ms) In condition A, TTI length is reduced to half, therefore the number of PDCCH monitoring increases to four times.However, due to not remaining identical PDCCH monitoring machine meeting, it is thus possible to increase the power consumption of terminal.

In short TTI situation B 6530, according to reduced TTI, the unlatching duration is reduced to 1ms from 2ms, and The number of PDCCH monitoring is also reduced to twice within a unlatching duration.However, because of the TTI according to reduction, DRX is followed Ring is also reduced to 3ms from 6ms, monitors so four PDCCH still are arranged for the time identical with normal TTI situation.Therefore, Between short TTI situation A 6520 and short TTI situation B 6530, the power consumption of terminal is constant.

Therefore, the present disclosure proposes following methods.That is, in DRX parameter, timing relevant to PDCCH monitoring Device (opening duration, inactivity timer etc.) is indicated by TTI, and other parameters are indicated by subframe.

With reference to short TTI situation C 6540, compared with normal TTI, the unlatching duration is reduced to 1ms from 2ms, and The number of PDCCH monitoring also remains twice within a unlatching duration.In addition, in DRX circulation 6ms, with normal TTI It compares, the number of PDCCH monitoring remains twice.In detail, open the duration, inactivity timer, ULRetransmissionTimer, StartOffset etc. can be indicated by TTI, and DRX circulation, shortCycleTimer etc. It can be indicated by subframe.

TTI length can be set by SI or RRC, but for the ease of dynamic dispatching, can be held in physical layer L1 The additional TTI of row or PDCCH resource setting.However, if TTI length be arranged according to additional TTI/PDCCH resource and dynamically Change, then may postpone when recalculating the timer on L2 layer.When scheduling/HARQ operation occurs in short TTI, The delay may cause problem.Therefore, the present disclosure proposes it is a kind of not by according to L1 signal and TTI that dynamic changes include Method in the calculating of MAC timer.According to embodiment, MAC is not included in by the variation in the specific time length of RRC setting During timer calculates, and the variation for being longer than specific time length may include in the calculating of MAC timer.

According to embodiment, RRC information can be arranged to terminal to define the length of the TTI of specific timer in base station.For example, The unlatching duration can be set to shortest TTI (0.25ms), and inactivity timer can be set to shorter TTI (0.5ms), and DRX circulation can be set to normal TTI (1.0ms).Furthermore, it is possible to preassign some ginsengs in a standard Number.For example, the length for the mini time slot being arranged in L1 can be depended on by opening the duration, and it can specify DRX circulation To follow the length for the time slot being arranged in L1.

According to embodiment, some parameters needed for DRX process can temporally unit be fixed, and other parameters can be set To change chronomere according to numerology.Base station can fix DRX circulation, shortCycleTimer etc. as unit of subframe.It opens Opening duration, inactivity timer, ULRetransmissionTimer and StartOffset can be with [time slot, when mini Gap] be that unit indicates, and by the control channel for using which unit that can be arranged according to base station, frequency band, the index in DCI and Any combination of TTI determines.For example, opening duration value if terminal receives control channel in the frequency band 1 of eMBB 4 are considered as 4 time slots, and if terminal receives control channel in the frequency band 2 of URLLC, when identical unlatching continues Between value 4 be understood to 4 mini time slots.

Figure 66 be show it is according to an embodiment of the present disclosure based on control channel monitoring period and transmitting continuous time come Determine the exemplary figure of TTI value.

It according to circumstances can differently be determined with reference to Figure 66 according to control channel monitoring period and transmitting continuous time The value of TTI.

In situation (a) 6610 and (b) 6620 in Figure 66, data channel only is distributed within the control channel observation period, So that the transmission cycle of scheduling is equal to control channel and observes the period.Therefore, TTI is equal to the control channel observation period.However, scheming Under 66 the case where (c) 6630, the transmitting continuous time is indicated as being longer than the control channel observation period, so that the transmission cycle of scheduling It is fuzzy.

This can change according to the control of base station.If base station has transmission longer than the control channel observation period Instruction terminal is on the transmission block of duration so as not to observe the control channel of overlapping, then TTI is equal to indicated transmitting continuous Time.However, base station can if base station instruction terminal observation control channel even during the transmitting continuous time observes the period Periodic scheduling terminal is observed with every control channel.Therefore, in this case, TTI is identical as the control channel observation period.

About the specific embodiment based on the operation of timer switch of frequency band as shown in Figure 54, Figure 55, Figure 56 and Figure 60 It is described below.The timer can be new timer, such as frequency band switching timer or frequency band validity timer, or It can be existing timer, such as DRX inactivity timer or the short cycle timer of DRX.

Figure 67 is the figure for showing the frequency band handover operation based on timer according to various embodiments of the present disclosure.
