Description

Semi-static resource scheduling method, Poewr control method and respective user equipment

Technical field

The present invention relates to wireless communication technology fields, more particularly, to a kind of semi-static resource scheduling method, power control Method and respective user equipment processed.

Background technology

NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) is one of all things on earth internet Important branch, NB-IoT can be deployed in the cellular network of the standards such as GSM, UMTS or LTE.For disposing in the lte networks NB-IoT, in order to support the enhancing of eMTC (enhancing machine type communication) or mMTC (magnanimity machine type communication) applications to cover field Scape, and meet the requirement (such as URLLC) of high reliability (reliability), it needs using the side for repeating (repetition) Formula is transmitted.It repeats transmission to need more to occupy the channel resource of PDCCH channels (down control channel), therefore under reduction The expense of row channel resource is the key that design high efficiency NB-IoT.

LTE system realizes that synchronizing for uplink is non-adaptive by PHICH channels (physical mixed automatic re-transmission indicating channel) It should retransmit.However, PHICH channels need reserved resource, this can still cause the waste of down channel resources.And PHICH channels There is no the protection of CRC (cyclic redundancy check), reliability there is no PDCCH channels high.Therefore, the introducing that is designed without of NB-IoT is used In the PHICH channels of transmission uplink ACK/NACK.

SPS (Semi-Persistent Scheduling, semi-persistent scheduling) is to be mainly used for reducing in LTE speech businesses A kind of technology of PDCCH channel overheads.In SPS technologies, the running time-frequency resource (including uplink and downlink) of system need to only pass through PDCCH channel distributions are specified primary, can then be repeated periodically and use identical running time-frequency resource.First, system is logical The parameter for crossing the RRC signaling configuration SPS patterns on upper layer, specifies the period of SPS while configuration.Then, SPS patterns are by base It stands and is activated by being the corresponding resource of UE (User Equipment, user equipment) distribution in PDCCH channels, UE preserves phase The resource allocation answered is reused within subsequent dispatching cycle, and the data of adaptive retransmission are needed through PDCCH channel weights New distribution resource.In the subframe of SPS transmission, base station can also be redistributed corresponding resource by PDCCH channels and is used for transmission. Finally, base station indicates release SPS by PDCCH channels.

However, the SPS scheduling of LTE system can only reduce the expense of descending scheduling at present, but base station still needs As usual the DCI (Downlink Control Information, Downlink Control Information) of a same format length scale is sent, UE still needs to monitor the PDCCH search that (monitoring) detects identical DCI format load (payload) size as usual Space cannot achieve the effect of power saving.In addition, must be dispatched and could will be swashed again after existing SPS scheduling methods activation The running time-frequency resource distributed when living is converted to by new biography data use retransmits data use, and directly can not indicate to attach most importance in activation Data are passed to use, this makes SPS scheduling methods not be suitable for the scene that big data quantity transmission and high-frequency retransmit in NB-IoT, and Scheduling again when conversion increases the expense of down channel.In view of this, it is necessary to provide one kind capable of solving above-mentioned technology The wireless communication resources dispatching method and user equipment of problem.

Particularly, in LTE system or NB-IoT systems, UE needs the PDSCH for monitoring PDCCH and PDCCH scheduling to come Obtain paging information.There is no the information of the UE for the paging information carried in the most of the time, PDSCH, then, this part solution The UE power consumptions of code PDCCH and PDSCH are wasted.Similar situation exists in the DRX of connected state, when UE is monitored When PDCCH, there is no the PDCCH of the UE.In order to reduce UE power consumptions, it is necessary to which machine is monitored in the paging or DRX for providing a kind of power saving System and user equipment.

In addition, for the terminal of some Internet of Things, due to business demand, it is deployed in interior or basement, these terminals Channel condition compared to common wireless communications terminal is poor.3GPP designs NB-IoT systems in Rel-13 and Rel-14, with And the new terminal type of eMTC is introduced in LTE system, and to LTE terminal, the characteristic of coverage enhancement has also been introduced (coverage enhancement feature).For NB-IoT terminals, 3 enhancing covering grade (enhanced are defined Coverage level), the configuration of each covering grade is broadcasted by system information.For eMTC, two kinds of coverings etc. are defined Grade (CE mode A and CE mode B).In LTE and NB-IoT systems, base station can configure the maximum transmission power of UE.Mesh No matter preceding NB-IoT systems and eMTC systems follow the maximum value of the configuration in any coverage condition.But increase for being in The UE of strong covering grade, does not play its ability well in this way, causes with the uplink of very short time transmission success to believe originally Road needs longer time tranfer.Not only waste of resource in this way, also has very major injury to the power consumption of UE.

Therefore, a kind of power control mode is designed, the UE that channel condition can be allow bad tries one's best to be emitted to Maximum power is advantageous.

Specific implementation mode

It is specific real below in conjunction with this in order to make those skilled in the art more fully understand present embodiment scheme The attached drawing in mode embodiment is applied, the technical solution in present embodiment embodiment is clearly and completely described.

In some flows of description in the specification and claims of present embodiment and above-mentioned attached drawing, packet The multiple operations occurred according to particular order are contained, but it should be clearly understood that these operations can not be according to it herein The sequence of appearance is executed or is executed parallel, and the serial number such as 101,102 etc. of operation is only used for distinguishing each different behaviour Make, serial number itself, which does not represent, any executes sequence.In addition, these flows may include more or fewer operations, and this A little operations can be executed or be executed parallel in order.

Below in conjunction with the attached drawing in present embodiment embodiment, to the technology in present embodiment embodiment Scheme is clearly and completely described, it is clear that and described embodiment is only present embodiment a part of the embodiment, Instead of all the embodiments.Based on the embodiment in present embodiment, those skilled in the art are not making creation Property labour under the premise of the every other embodiment that is obtained, belong to the range of present embodiment protection.

Referring to Fig. 1, present embodiment semi-static resource scheduling method includes the following steps：

Step 1001, the down channel control information DCI for monitoring the first format group format, according to the first format group The instruction activation semi-persistent scheduling SPS of the DCI of format；

Step 1002, the DCI for monitoring second of format group format, according to the instruction of the DCI of second of format group format SPS is discharged, DCI format load (payload) size of second of format group format is less than the first described format group lattice The DCI format load of formula.

Wherein, DCI format load refers to the number of information bit in DCI, may also be referred to as DCI format length.

Referring to Fig. 2, the following activation for illustrating present embodiment semi-static resource scheduling SPS first.

UE retrieves PDCCH channels and monitors the down channel control information DCI of the first format group format.If UE is successfully solved The code CRC check position scrambled DCI of SPSC-RNTI, and further whether verification (such as is verified the value in certain domains in the DCI and is accorded with Close and require) success, then it is assumed that the DCI is that SPS activates DCI.Wherein, SPS C-RNTI are configured for base station by RRC specific RNTI。

UE judges the data of resource (PDSCH channels and/or PUSCH channels) institute's transmission data scheduled in SPS activation DCI Type, i.e.,：It is for the transmission of first transmission data (hereinafter referred to as new data) or for retransmitting data (hereinafter referred to as legacy data) Re-transmission.If the resource scheduled in SPS activation DCI is the transmission for dispatching new data, indicated by SPS activation DCI Receive or send new data in resource.If the resource scheduled in SPS activation DCI is the transmission for dispatching legacy data, in SPS It activates and receives or send the legacy data retransmitted in the resource indicated by DCI.Base station can by UE configure different RNTI come For distinguishing uplink and downlink transmission.Or base station can indicate to be used to indicate upstream or downstream transmission by DCI.

After SPS activation, UE retrieves PDCCH channels and monitors the DCI of second of format group format.

Wherein, a kind of DCI format group can include one or more DCI formats, and the length scales of a variety of DCI formats can be with It is identical can not also be identical.For the first format group, one or two kinds of DCI formats are preferably included.For second of format group, Preferably include a kind of DCI format.UE in this way will not become excessively complicated to the blind examination of DCI, it is possible to reduce the work(that UE blind examinations generate Consumption.A kind of DCI format can be the format for dispatching uplink data transmission, or for dispatching downlink data transmission Format.For example, the first format group includes any one or two kinds of formats in N0, N0-A, N1, N1-A, N2 and N2-A, In, N0, N0-A are the format for dispatching uplink data, and N1, N1-A are for dispatching downlink data, carrying SC-MTCH (Single Cell-Multicast Traffic Channel, single cell multicast service channel) or notice SC-MCCH The format of (Single Cell-Multicast Control Channel, single cell multicast control channel) variation, N2, N2-A To be used for the NPDSCH of the DCI, scheduling of paging channel (paging), directly instruction system information variation for carrying SC-MCCH Or the format of notice SC-MCCH variations.Second of format group includes any one format in N0-B, N1-B, N2-B, wherein N0-B is the format for dispatching uplink data, and N1-B is the format for dispatching downlink data, and N2-B is for paging channel (paging) or the format of SC-MCCH.

The load (bit number) of DCI format is less than the negative of DCI format in the first format group in second of format group Carry size (bit number).Appoint for example, the format length of N0-B, N1-B, N2-B are respectively less than in N0, N0-A, N1, N1-A, N2, N2-A It anticipates a kind of format length.

For example, the DCI format in second of format group deletes part domain by the DCI format in the first format group (field) it is obtained after.Such as, the DCI format in second of format group only includes data channel (PDSCH and/or PUSCH) repetition time Number field and the domain NDI (New Data Indicator).

For another example, if the SPS of UL and DL is activated simultaneously, the DCI format in second of format group can further include Domain for differentiating uplink and downlink scheduling.For descending scheduling, the ACK/NACK information of instruction transmission HARQ can be further included Resource domain (calling the domains HARQ-ACK resource in the following text), or further include scheduling delay (scheduling delay) Domain (including time-domain resource initial position and/or occupy duration), the domain resource allocation (resource assignment) (including account for With frequency domain resource position), it is one or more in modulation coding scheme domain.For uplink scheduling, sub- load can be further included Wave instructions field, scheduling of resource domain, scheduling delay domain, modulation coding scheme domain, redundant version number (Redundancy version) It is one or more in domain.

In another example, the load of DCI format is equal to DCI lattice in the first format group in second of format group The load of formula.At this point, the format for monitoring second of format group DCI is not intended to reduce UE power consumptions.And reduce downlink expense It can be by the way that the form of the information sharing of multiple users together be realized.For example, DCI format in second of format group can be with For the format of multiple users to share, wherein oneself corresponding domain can be calculated in each user, wherein can carry one or The ACK/NACK information of the ACK/NACK information of the multiple HARQ of person, the HARQ can be single state (ACK or NACK) or multimode (ACK and NACK).Further, it is possible to carry the information such as frequency hopping (frequency hopping) triggering.

Under extreme case, the DCI format in second of format group can degenerate for 1 bit information, i.e. a UE is specific Sequence or waveform.For example, one plus around RNTI sequences.The RNTI can be that user is specific, user group is specific or cell is special Fixed.This 1 bit, either seldom bit new DCI format can be adapted for uni-cast or broadcast (for example, paging Information, system information) or multicast message (SC-PTM (and single cell Point To Multi-point, single cell a little it is right Multiple spot) in SC-MCCH or SC-MTCH).

Referring to Fig. 3, for scheduler latency, the initial position of PUSCH can be preset value.Such as first time SPS tune The transmission initial position of the PUSCH/PDSCH of degree is that the PDCCH where SPS activates DCI terminates the set time after subframe (such as Received on PDSCH after transmission or 4ms on PUSCH after 8ms) start afterwards.The set time can appoint in advance in a standard It is fixed, or configured by upper layer RRC signaling.Scheduler latency can also be activated DCI instructions (to retain scheduling delay at this time by SPS Domain).In the present specification, the chronomere of scheduler latency can be absolute time (such as millisecond ms) or symbol (symbol)/ Time slot (slot)/subframe (subframe) can also be available symbols/time slot/subframe (such as uplink or downlink subframe or base station The available subframe etc. of configuration).Clear in order to describe, the chronomeres such as scheduler latency or time-domain position hereinafter are with son Frame is used as example and illustrates.For example, the transmission initial position of the PUSCH/PDSCH of first time SPS scheduling is by DCI Scheduler latency domain indicates that each periodic transfer hereafter adds a fixed value (such as the initial position of first time PUSCH/PDSCH 20ms, 40ms, 80ms etc.), which is configured by upper layer RRC signaling.Alternatively, the period of SPS is PDCCH period (PDCCH Period, PP) multiple, such as 1PP, 2PP, 4PP, 8PP ....In addition, in order to support the longer SPS periods, the configuration in period can With by configuring superframe (hyper-frame), system-frame (radio frame), system subframe (subframe), time slot (slot), the mode that a variety of dimensions such as symbol (symbol) are combined.The SPS periods are by dynamic dispatching (the new domains DCI) come real It is existing.Such as：One DCI can dispatch multiple running time-frequency resource positions (or time-domain resource position, using identical frequency domain resource, or Frequency hopping (frequency hopping), which is carried out, by preconfigured mode obtains frequency domain resource.

There is more macrocyclic SPS, SPS can be used for paging information.In order to which UE still may be used in idle state (IDLE) To record the SPS periods, which can be allocated to UE by core net.For being sought with SPS scheduling of resource The case where exhaling, UE can determine whether oneself to be paged by detecting whether the UE marks of oneself.This mark can lead to It crosses a kind of sequence to realize, either be pointed out by the information carried in PDSCH or PDCCH or can be by a kind of scrambled RNTI is pointed out.It can also be pointed out by way of PDSCH or PDCCH and RNTI different scrambling codes.Similar, this SPS can For DRX.UE is without monitoring PDCCH and directly monitoring downlink data information.

For DCI numbers of repetition domain, the initial position of the PUSCH or PDSCH of scheduling can with the initial position of PDCCH, PDCCH search space initial position or one make an appointment (or upper layer RRC signaling configuration) initial position (such as subframe, Frame etc.) it determines.In this case, DCI numbers of repetition domain can be set as pre-defined value, such as entirely " 0 " or complete " 1 ", The original transmission position of PDSCH or PUSCH is determined without the position terminated by PDCCH.

Referring to Fig. 4, for the domains HARQ-ACK resource, for being fed back for the data received on PDSCH The resource location (including time domain and/or frequency domain) of ACK/NACK information of HARQ can be preset value.Such as HARQ-ACK The domains resource are set as complete " 0 " or do not include the domains HARQ-ACK resource.For example, its time-domain position is the after PDSCH 13 subframes uploads are defeated, and frequency domain resource is that subcarrier 45 (when group intercarrier is divided into 3.75kHz) or subcarrier 0 (work as subcarrier Between when being divided into 15kHz).At this point, the domains HARQ-ACK resource in DCI format N1 are set to " 0000 ", as shown in table 1. Alternatively, the time domain or frequency domain or time-frequency domain resources of the HARQ-ACK feedbacks for being used for PDSCH are configured by upper layer RRC signaling, Such as pass through SPS-Config information either SPS-ConfigDL information or SPS-ConfigUL information configurations.In addition, The resource location of ACK/NACK information can be determined by the domains HARQ-ACK resource, can take only fixed time domain or Person's frequency domain position, and the frequency domain that accordingly can be changed or time-domain position are indicated by the domains HARQ-ACK resource.

Special domain configuration example in table 1 SPS scheduling activation DCI

For version redundancy number, when SPS is only used for new data transmission, if it does, redundant version number can be to fix Value, such as 0.With C-RNTI add around DCI trigger retransmit when, thus it is possible to vary redundant version number improves decoding performance.Work as SPS When being retransmitted for legacy data, without additional instruction redundant version number.Redundant version number when it retransmits or repeats to transmit every time can To carry out repeating query, the .. for example, 0,1,0,1 ... by the sequence made an appointment.

SPS may be applied to the preferable scene of signal coverage condition, in this case, the data channel in DCI The number of repetition domain (PDSCH and/or PUSCH) is limited to be necessarily less than some fixed value.When data channel number of repetition in DCI When more than the fixed value, UE thinks verification not over SPS is activated not successfully.Similar, DCI number of repetition (if present)s It is considered as just successful SPS activation that a fixed value, which can also be necessarily less than,.

For the domains NDI, UE by NDI come judge SPS activate DCI scheduled in resource be for new data transmission or Re-transmission for legacy data.The transmission of new data is if it is for, then is received on the scheduling resource indicated by SPS activation DCI Or new data is sent, and carry out HARQ processing according to new transmission.The re-transmission of legacy data is if it is for, then is activated in SPS It is received on scheduling resource indicated by DCI or sends legacy data, and HARQ processing is carried out according to the legacy data of re-transmission, such as connect Union operation is carried out after receiving legacy data, or re-read the inner caching (buffer) of HARQ entities (entity) to need to retransmit to send Legacy data.

For HARQ process numbers domain, UE judges H ARQ process numbers according to the multiple HARQ processes of activation are judged whether there is, such as Fruit does not activate multiple HARQ processes, then it is assumed that only 1 HARQ, if there is activating multiple HARQ processes, then UE is further true Determine HARQ process numbers.When HARQ into number of passes be it is multiple when, SPS activate DCI in NDI simultaneously be suitable for multiple processes, that is, be applicable in It retransmits and judges in the new data or legacy data of multiple processes.However, when wherein one or more HARQ processes are to transmit for the first time When, then newly to transmit.In addition, when supporting more HARQ processes, a use can be carried in the DCI format of second of format group simultaneously The ACK/NACK of multiple HARQ processes at family is fed back.For example, the UE for supporting multiple HARQ processes, UE are continued to use in LTE and are determined The mode of HARQ process numbers determines HARQ process numbers, i.e.,：HARQ Process ID=[floor (CURRENT_TTI/ semiPer sistSchedIntervalDL)]modulo numberOfConfSPS-Processes.Wherein, CURRENT_ TTI=[(SFN*10)+subframe number].Alternatively, the instruction of HARQ process numbers in DCI can be retained, in particular for When SPS for re-transmission is dispatched.The re-transmission of two such HARQ processes can be carried out by way of intertexture.More specifically, exist In the NB-IoT systems of Rel-14 versions, 2 HARQ processes are could support up.NumberOfConfSPS-Processes is most at this time It could be provided as 2 more.

For bandwidth block Bandwidth part (BWP) instructions field, can be retained in activation DCI, for supporting activation BWP frequency domain positions.It can not also be retained in activation DCI and (e.g., delete or be set to predetermined value).At this point, being transmitted for SPS BWP can be the previous BWP that had activated, or pass through high-rise configuration.It is equally applicable to the uplink without DCI activation Pattern.

For additional uplink SUL (supplementary uplink) and UL carrier wave instructions field, SPS activation can be retained in In DCI.As the uplink based on scheduling, which can serve to indicate that the SPS on activation SUL or UL.

After SPS successful activations, UE monitors the DCI of second of format group format.UE monitors the DCI of second of format group format When, the specific search spaces UE or the specific search space of cell (cell-specific search space) can be monitored, or The specific search space of person's UE groups (group-specific search space).The DCI that UE monitors second of format group format can It is decoded, or can be decoded using a specific RNTI of UE groups with using SPS C-RNTI and/or C-RNTI, or It can be decoded using the N-RNTI different from SPS C-RNTI or C-RNTI.

Further, after SPS successful activations, UE can also be while listening for the DCI of the first format group format and second The DCI of kind format group format.Two kinds of DCI formats can be carried on identical PDCCH search space or different PDCCH search Space, such as different Rmax (maximum number of repetitions), different search space head pointer positions (such as different offsets) is different Search space type (the specific search spaces such as UE, the specific search space of cell, the specific search space of UE groups).

Referring to Fig. 5, the release process of present embodiment semi-static resource scheduling SPS introduced below.

UE retrieves PDCCH channels and monitors the down channel control information DCI of second of format group format.If UE is successfully solved The code CRC check position scrambled DCI of SPSC-RNTI, and further whether verification (such as is verified the value in certain domains in the DCI and is accorded with Close and require) success, then it is assumed that the DCI is that SPS discharges DCI, and sends and release in the resource of the ACK/NACK information in transmission HARQ The ACK information for putting SPS understands the wrong area of SPS to avoid between base station and UE.

Similar with SPS activation DCI, SPS discharges some domains in DCI without instruction, such as HARQ process numbers domain, subcarrier Instructions field (frequency domain resource of PUSCH), resource allocation field, scheduler latency domain, redundant version number domain, modulation coding scheme domain, DCI Subframe number of repetition domain, SUL or UL instructions field is one or more in the domains BWP, as shown in table 2.

Special domain configuration example in the DCI of table 2 SPS releases

UE send release SPS ACK information transfer resource (i.e. transmit HARQ ACK/NACK information resource, including Time domain and/or frequency domain resource) by SPS release DCI instructions, it is either configured by upper layer RRC signaling or for value (example of making an appointment As provided in a standard).

Referring to Fig. 6, when UE sends the transfer resource of the ACK information of release SPS by SPS release DCI instructions, time domain Position can be determined by the transmission location of PDCCH, such as UE starts to send out after t subframe of the last one transmission subframe of PDCCH The ACK message of release SPS, wherein t is sent to be indicated by the domains HARQ-ACK resource in DCI format N1, HARQ-ACK The domains resource indicate subcarrier in frequency domain position simultaneously.And for being used to indicate the DCI format N0 of PUSCH transmission, without HARQ- The domains ACK resource can retain the subcarrier instruction (subcarrier in DCI format N0 in this case Indication) domain and the scheduling delay domain (scheduling delay) indicate running time-frequency resource, or pass through and rewrite DCI lattice Some domains in formula N0 are realized.For example, 4 of 4 bit or modulation coding scheme domain in 6 bit of subcarrier instructions field A bit, or following domain one or several combinations：Subcarrier instructions field, resource allocation field, scheduler latency domain, modulatedemodulate Adjust domain, redundant version number domain, number of repetition domain, DCI subframe numbers of repetition domain etc..

When the transfer resource that UE sends the ACK information of release SPS is configured by upper layer RRC signaling, such as pass through SPS- Config information, SPS-ConfigDL information or SPS-ConfigUL information configurations.Further, in another example, frequency domain provides Source is configured by upper layer RRC signaling, but time-domain resource is indicated in (such as reuse scheduling delay domain etc.) by DCI.

The re-transmission application of SPS introduced below retransmits application after i.e. SPS activation to the HARQ between SPS discharges.It needs to illustrate , the semi-static resource scheduling method of present embodiment can transmission be new on first scheduling resource after SPS activation Data, and some scheduling resource behind starts transmission and retransmits legacy data；Simultaneously can also SPS activation after first tune All transmission retransmits legacy data to the resource of the resource of degree the last one scheduling before SPS releases, and the downlink to reduce scheduling is believed Road expense.

In addition, the semi-static resource scheduling method of present embodiment equally supports the SPS dynamic similar with LTE to adjust Degree, i.e., in SPS transmission processes, base station can also redistribute corresponding resource (time-frequency location of such as resource, week by DCI Phase etc.) it is used for transmission, difference lies in the DCI that UE in present embodiment monitors second of format group format.Such as Fig. 7, UE at Work(decodes one with the scrambled DCI of C-RNTI, wherein indicating 4 re-transmissions.Then, swashing for SPS has been successfully decoded in UE again It is living, wherein only indicating 1 re-transmission.In the gap in SPS periods, UE or base station can verify whether successfully to receive, and loopback ACK letters Breath transmits to terminate, or new transmission is sent out by loopback ACK information.

SPS scheduling for transmitting uplink data, if the wire data type that SPS activation DCI is determined is new data, UE New data is sent in the resource of SPS distribution, until receiving corresponding nack message, UE is sent in the resource that SPS is distributed The legacy data of re-transmission.

It is dispatched by PDCCH 200 referring to Fig. 8, just passing, re-transmission is dispatched by down channel 201.UE is in up channel After having sent new data (just passing), the down channel 201 of loading ACK/nack message is detected.If UE is received in down channel 201 To nack message, then trigger re-transmission, wherein the number of repetition retransmitted be different from the number of repetition that just passes or with the repetition time that just passes Number is identical.During thereafter, UE sends always the legacy data of re-transmission in the resource of SPS distribution, until UE is being received ACK information, or maximum retransmission is reached, or reach the resource of the last one SPS distribution.In Fig. 8, UE is in down channel 201 With 202 in detect ACK message, but detect ACK message not successfully, then UE continues to retransmit in resource 212.But UE believes in downlink Road 203 detects ACK message, then UE, which is terminated, retransmits.

SPS scheduling for transmitting uplink data, if the wire data type that SPS activation DCI is determined is legacy data, UE The legacy data of re-transmission is sent in the resource of SPS distribution, until receiving corresponding ACK information, UE stops sending the old of re-transmission Data.This mode can effectively reduce signaling overheads, avoid the wasting of resources.

It is dispatched by PDCCH 200 referring to Fig. 8, just passing, re-transmission is dispatched by down channel 201.UE is in up channel After having sent the legacy data of re-transmission, the down channel 201 of loading ACK/nack message is detected.If UE is received in down channel 201 To nack message, then UE continues to retransmit in resource 211.During thereafter, UE is detected in down channel 201 and 202 NACK message, if UE detects NACK message not successfully, UE is on the following resource since resource 212 without passing It is defeated.Alternatively, during thereafter, UE detects NACK message in down channel 201 and 202, if UE is detected not successfully NACK message, then UE in resource 212 without transmission, disappear if UE successfully is detected NACK in subsequent down channel 203 Breath, then UE sends the legacy data of re-transmission in resource 213, i.e., detects the operation after NACK message only for one not successfully SPS resources are effective, and the counterweight biography that this mode can make base station more flexible is scheduled.

It just passes and is dispatched by PDCCH 200, retransmitted through the scheduling of down channel 201 (display scheduling or implicit scheduling).UE After up channel has sent data, the down channel 201 of loading ACK/nack message is detected.If UE is in down channel 201 Or 202 or 203 receive ACK information, then stops retransmitting since corresponding resource 211 or 212 or 213.If UE is not received always To ACK information, then retransmit always until reaching maximum retransmission or using up SPS resources.

In several examples above, time domain, frequency domain or the time-frequency domain position of resource 210 and/or resource 211,212,213 Parameter provided by physical layer, such as the DCI in DCI, such as PDCCH 200 or down channel 201.Resource 210 and/or resource 211, the parameter of 212,213 time domain, frequency domain or time-frequency domain position can also pass through upper layer RRC or MAC signal deployment, Huo Zhetong The mode that top signaling configuration and physical layer instruction are combined is crossed to provide.The number of repetition of re-transmission can pre-define, or (such as 201) dynamic configuration in down channel.Down channel 201 can be PDCCH channels or the ACK/ for being used for transmission HARQ The PHICH channels of nack message.

SPS scheduling for downlink data transmission, if the wire data type that SPS activation DCI is determined is legacy data, UE The legacy data for receiving and decoding re-transmission in the resource of SPS distribution up to the re-transmission legacy data successfully decoded received and sends phase After the ACK information answered, UE stops at the legacy data that re-transmission is received in the resource that SPS is distributed.Further, UE will continue at SPS points New data is received in the resource matched.

Referring to Fig. 9, UE obtains PDSCH by PDCCH300 just passes resource 310.UE by down channel 300 and/or 301 obtain PDSCH retransmission resources 311,312 and 313.UE receive and decode transmitted on 310 PDSCH (can be new data, Can be the legacy data retransmitted), if the decoding is successful, then sending ACK information, or any information is not transmitted.If base station success Ack signal is received, then will not send down channel 301 to dispatch the re-transmission of PSDCH.Correspondingly, UE does not expect to be useful for retransmitting SPS scheduling informations.Further, if what is transmitted in resource 310 is new data, UE continues in resource 311,312 and 313 Receive the decode new data.If what is transmitted in resource 310 is the legacy data retransmitted, UE thinks retransmission resource 311,312 and 313 It is released.

SPS scheduling for downlink data transmission, if the wire data type that SPS activation DCI is determined is new data, UE New data is received in the resource of SPS distribution, until after the new data decoding received fails and sends corresponding nack message, UE receives the legacy data of re-transmission in the resource that SPS is distributed.

SPS scheduling for downlink data transmission, if the wire data type that SPS activation DCI is determined is legacy data, UE The legacy data of re-transmission is received and decoded in the resource of SPS distribution, if the re-transmission legacy data decoding failure received, UE Corresponding nack message is sent or do not sent, and continues to receive the legacy data of re-transmission in the resource that SPS is distributed.

Referring to Fig. 9, UE obtains PDSCH by PDCCH300 just passes resource 310.UE by down channel 300 and/or 301 obtain PDSCH retransmission resources 311,312 and 313.UE receive and decode transmitted on 310 PDSCH (can be new data, Can be the legacy data retransmitted), if decoding failure, is handled by following two modes：

(1) if what is transmitted in resource 310 is new data, UE sends nack message, and base station is properly received the nack message, Base station retransmits legacy data, and UE receives the legacy data of re-transmission in resource 311 and following resource；

(2) if what is transmitted in resource 310 is to retransmit legacy data, UE sends or does not send (such as DTX) nack message, base station The nack message is correspondingly received or does not receive, base station continues to retransmit legacy data, and UE is in resource 311 and following resource after continued access Receive the legacy data retransmitted.

In several examples above, time domain, frequency domain or the parameter of time-frequency domain position of resource 311,312,313 pass through physics Layer provides, such as the DCI in DCI, such as PDCCH 300 or down channel 301.The time domain of resource 311,312,313, frequency domain or when The parameter of frequency domain position can also refer to by upper layer RRC or MAC signal deployment, or by top signaling configuration and physical layer Show that the mode being combined provides.The number of repetition of re-transmission can pre-define, or (such as 301) dynamically match in down channel It sets.Down channel 301 can be PDCCH channels or be used for transmission the PHICH channels of the ACK/NACK information of HARQ.

In addition, in order to maintain lower UE complexities, the SPS of UL and DL can be activated when activating SPS simultaneously.Then, UE A DCI load can be monitored, and obtains two kinds of scheduling of uplink or downlink simultaneously.Optionally, UE is activated in SPS Afterwards, on the basis of PDCCH number for reducing number or the original monitoring of maintenance that original PDCCH is monitored, then a difference is additionally monitored The DCI or wake-up signal of size.The position of the DCI additionally monitored is also pre-defined, or is configured according to high level, Huo Zhegen According to searching for original PDCCH search space (such as search space initial position or search space end position) or original PDCCH The position (starting or end position) of each candidate PDCCH determines in rope space.Specifically, for example, additionally identifying The position of PDCCH starts in the end position of each candidate's PDCCH time-frequency locations.Since in descending scheduling, eMTC may have The scheduler latency of 1ms, NB-IoT have the scheduler latency of minimum 4ms, therefore, if the PDCCH of new small size can be transmitted In the resource of this scheduler latency, downstream spectrum efficiency can be improved to the greatest extent.Similar, in NR (New Radio) system In system, if UE monitors the size of different DCI, the search space of small DCI can be according to the big search spaces DCI or candidate The running time-frequency resource position of PDCCH determines.

In the NR systems of 3GPP, the mode of more flexible configuration frame structure is introduced.RRC can be first passed through to be configured to The time slot and symbol of uplink, and time slot and symbol for downlink transfer.And it can be by the uplink that configures Downlink transfer period (dl-UL-TransmissionPeriodicity), UE can calculate middle section and can carry out flexibly The subframe of configuration and the position of symbol.This part can be indicated by time slot format (slot format indicator, SFI it) is dynamically indicated.The permission of SFI is higher than semi-static configuration, such as measures, CSI (Channel status Information return), in the transmission of SRS (sounding reference signal) and semi-persistent scheduling (SPS) Row (also makes no scheduling (grant free) uplink, or the uplink based on configuration schedules (configured grant) pass Defeated either semi-continuous scheduling) or SPS downlink transmission.That is, when UE obtains SPS uplinks (or downlink) by RRC and configures, UE It can be to send uplink letter on identical uplink (or downlink) time slot or symbol being semi-statically configured in downstream transmission direction Number (or receive downlink signal).Similar, for uplink (or downlink) SPS activated by DCI, first is activated The resource of DCI instructions can be taken as by the resource of DCI dynamic dispatchings, and subsequent SPS resources regard measurement, that is, are less than SFI priority.It (but cannot be with RRC half higher than priority that SFI rewrites by the priority of the resource of DCI dynamic dispatchings The up-downlink direction conflict of static configuration).Same principle is readily applicable to according to activation DCI instructions for sending first Ascending HARQ-ACK the resources of a DL SPS transmission, i.e. its priority are higher than SFI, can rewrite the uplink and downlink or flexibly sub of SFI The direction of frame/time slot/symbol, and other priority for sending the ascending resource of HARQ-ACK feedbacks are equal to measurement Priority can be rewritten by SFI.Alternatively, the priority for whole HARQ-ACK is equal to measurement, you can with by SFI It rewrites.Alternatively, the priority for whole HARQ-ACK is equal to dynamic DCI scheduling, you can to rewrite SFI.

The transmission of HARQ-ACK feedback information is cancelled.

Referring to Fig. 10, when the ascending resource for the HARQ-ACK for being used to send DL SPS is rewritten as flexible resource by SFI, or When person's downlink resource, the transmission of HARQ-ACK can be delayed on (postponed) to next ascending resource.Wherein, next A ascending resource can be one or more sub-frame of uplink/time slot/symbol, can completely transmit HARQ-ACK message.When When HARQ-ACK has repetition, next ascending resource can be delayed, until completing to go whole repetitions.For each The PDSCH resources of SPS scheduling are as above operated respectively.

Alternatively, when the ascending resource for the HARQ-ACK for sending DL SPS is rewritten as flexible resource or downlink resource by SFI When, the transmission of HARQ-ACK is cancelled (cancel), i.e., does not send.When HARQ-ACK, which exists, to be repeated, as long as there are one Ascending resource cannot be sent, then be cancelled the transmission of HARQ-ACK.As shown in Figure 10, at this point, because base station knows that UE will not HARQ-ACK feedbacks are provided, then can specify that base station does not send PDSCH on changing DL SPS resources, at this point, UE is without decoding The PDSCH of downlink SPS.Can also base station continue to transmit, UE also continues with the decoding of SPS PDSCH, but and without Feedback.In above-mentioned example, the HARQ-ACK of DL SPS can be sent in the uplink or flexible resource of SFI instructions, only cannot It is sent in downlink resource.

The HARQ-ACK of DL SPS can be transmitted with the HARQ-ACK of other PDSCH on a UCI, wherein other PDSCH can be from DL SPS on identical descending carrier or different descending carriers (carrier wave polymerization).As only DL SPS PDSCH HARQ-ACK when being transmitted on PUCCH, and the PDSCH transmission of DL SPS due to by SFI rewrite and cancel when It waiting, the HARQ-ACK of the PDSCH of corresponding DL SPS can not be transmitted, and can save PUCCH resource in this way, or transmit HARQ-ACK information bits are NACK.It is the PDSCH based on scheduling to please refer to Fig.1 1, PDSCH 1, is transmitted on carrier 1, PDSCH 2 is the downlink transfer (can be the PDSCH based on scheduling or SPS) on carrier wave 2, is matched according to the HARQ-ACK times It sets, the HARQ-ACK of these three PDSCH is transmitted on identical UCI.Then, when this time of the DL SPS on carrier wave 1 transmit due to When being rewritten and cancelled by SFI, the information bit of the UCI of corresponding transmission DL SPS can be NACK.Or without feeding back, Reduce the information bit number of UCI.Since base station and UE have identical understanding, so there is no problems for decoding.Particularly, When scheduling request SR (scheduling request) is fed back with the HARQ-ACK for DL SPS in same time (or when Between on partly overlap), according to the rule based on scheduling, HARQ-ACK feedbacks can be sent in the resource of SR.If SPS's When the transmission of PDSCH is cancelled, the sequence of SR is sent in the resource of SR at this time.Or it can send NACK's in SR resource Sequence.

2 are please referred to Fig.1, user equipment of the present embodiment for semi-static resource scheduling includes：

The course of work of active module and release module corresponds respectively to present embodiment semi-static resource scheduling side The step 1001 of method and 1002, details are not described herein again.

Being described in the explanation to SPS activations above can be by configuring superframe, system-frame, and system subframe etc. is more The mode that kind dimension is combined realizes more macrocyclic SPS, can be by SPS when the resource of SPS distribution has the longer period Approach application in paging service or apply to DRX (Discontinuous Reception, discontinuous reception) (from the point of view of broadly, Paging service belongs to one kind of DRX business).A kind of SPS methods applying to paging service introduced below.The above method can fit For uplink.

3 are please referred to Fig.1, step 2001, SPS is obtained and distributes resource.

UE completes SPS activation, obtains PDSCH the or PUSCH running time-frequency resources for the periodic distribution that base station is distributed.Specifically Ground, when UE obtains PDSCH or PUSCH that base station is distributed by high-level signaling configuration (the specific RRC of UE or system information) Frequency resource.If desired UE can still record the SPS periods in idle state (IDLE), then base station leads to SPS period assignment information It crosses high-level signaling (such as network attached storage NAS signaling) and is allocated to UE, when UE needs to calculate the SPS periods, can pass through UE's High level obtains.

Step 2002, wake-up signal is detected.

UE monitors the wake-up signal (wake-up signal) that base station is sent, and when UE listens to wake-up signal, UE knows Base station may need to send paging information to oneself.Whether UE has the mark of oneself by detecting in the wake-up signal (UE is marked Know), the mark that changes of the mark (UE groups mark) of UE paging groups where oneself or system message, to judge whether oneself is sought It exhales.Hereinafter referred to as UE marks, UE groups mark or system message change are identified as paging mark.

UE by base station configuration information (such as system information) or high-level signaling (such as NAS signaling), obtain wake-up signal when Frequency resource location.For example, base station can configure the initial position of wake-up signal by RRC information (such as system information), it is such as following One or more of information：System-frame SFN, system for super-frame HFN and subframe numbers.Similar, base station configures wake-up signal Frequency domain resource position, such as one or more of following information：The serial number of Physical Resource Block PRB, non-anchor (anchor) carrier wave Frequency point.Base station configures wake-up signal and occupies running time-frequency resource size, for example, PRB time domains or the number of frequency domain, wake-up signal repeats secondary Number etc..Running time-frequency resource can pre-define in a standard, such as when NB-IoT systems are independently disposed, using before specific sub-frame 3 One or more of a OFDM symbol；For another example, in the previous or k of paging subframe (PO), (k is standard definition to wake-up signal Fixed value, or RRC signaling or physical layer signaling are passed through by base station and configured) effectively in subframe or absolute subframe, in another example In son, k can be the number of time slot or symbol.In addition, wake-up signal can also be transmitted according to treaty rule on PDCCH, or Person is transmitted on other channel resources other than PDCCH and PDSCH.

UE obtains the transmission form of wake-up signal by base station configuration information (such as system information) or high-level signaling.It wakes up Signal can be any form below：A kind of sequence, a kind of signal waveform (waveform), a kind of DCI format, one kind Special domain (such as number of repetition domain) in DCI format, a kind of scrambler for scrambling PDCCH.For example, the form of wake-up signal For：The sequence that 1 bit information in extreme circumstances generates after being modulated by coding (such as repeated encoding).For another example, wake-up signal Form be：The sequence and be used for decoded pilot frequency sequence that 1 bit information generates after being modulated by coding (such as repeated encoding) The sequence collectively formed.UE can be adjudicated by Sequence Detection (such as coherent detection, energy measuring) or by decoding, even A variety of receiving terminal algorithms such as CRC check are to determine whether there is the paging information of oneself.For another example, the form of wake-up signal is RNTI sequences The waveform of row is either obtained according to the RNTI signal waveforms generated by coded modulation or according to RNTI by coded modulation Signal and the signal waveform etc. that constitutes jointly of pilot signal for demodulation.

Step 2003, if successfully being detected the wake-up signal, PDSCH is decoded in acquired SPS distribution resources Or transmission PUSCH.

UE judges after oneself being paged, the PDSCH running time-frequency resources for the SPS periodic distributions that UE is further distributed in base station The relevant information of upper decoding paging service (or other DRX business, when this method applies to DRX business, such as uplink service) And data.If wake-up signal instruction system information variation (i.e. wake-up signal include system message change mark), UE into One step directly decodes system information on PDSCH the or PUSCH running time-frequency resources that base station is distributed.For another example, if wake-up signal refers to Show that system information changes, then UE further decodes paging service letter on PDSCH the or PUSCH running time-frequency resources that base station is distributed Breath further obtains the instruction of specific system information variation from decoded paging service information.In this way, UE can be directly acquired The system information of variation is more advantageous to saving energy consumption without decoding the system information not changed.

PDSCH decode or the required information of PUSCH transmission can in the following manner in one or more acquisitions： The information instruction of RRC, the rule made an appointment, wake-up signal.PDSCH or the required information of PUSCH transmission are decoded, including following One or more of information：Time-domain resource position (e.g., originates subframe, occupy transmission time), and frequency domain resource position repeats secondary Number, code modulation mode, transport block size (TBS), HARQ serial numbers etc..It is decoded for PDSCH for example, base station directly configures one Or the TBS of PUSCH transmission.For another example, base station can configure UE number for returning paging in paging information every time, or UE of paging Number can also be fixed in a standard in advance, such as 1 UE.Bearing call letter can be calculated in UE according to UE number of the paging The TBS of the PDSCH of breath.The UE number paged every time can also be indicated by wake-up signal.

It please refers to Fig.1 4, UE and monitors a wake-up signal, if UE successfully is not detected on current running time-frequency resource 401 Paging mark in the wake-up signal then continues the time-frequency money for keeping idle state until next wake-up signal for needing to monitor Source 402；If UE successes detect the mark of the paging in wake-up signal on running time-frequency resource 402, continue SPS points behind With decoding PDSCH or transmission on running time-frequency resource (such as in running time-frequency resource 411 and the period profile resource of follow-up other SPS distribution) PUSCH.Wherein, the wake-up signal that UE is monitored can only have very small load (payload), for example, SPS wake-up signals are The form of DCI, and the bit number of the DCI is very small.Or in extreme circumstances, wake-up signal is the form of a RNTI, such as 8 The bit either RNTI of 16 bits or 24 bits.

The case where present embodiment SPS applies to DRX is similar with the case where applying to paging service, does not go to live in the household of one's in-laws on getting married herein It states.Compared to paging or DRX in LTE by the way of general DCI, the method for present embodiment is not necessarily in PDCCH Preceding extraly increase wakes up channel, so as to ignore the decoding of PDCCH, and wake-up signal can be designed to have it is very small Load, effectively reduces the decoding time of UE, reduces the power consumption of UE so that UE more power savings.Similar method can be equally used for The channel of broadcast multi-broadcasting MBMS, or single cell point to multi--point transmit SC-PTM.

In addition, flexibility and low-power consumption in order to balance, can configure in such a way that base station configures and (such as pass through RRC) It either indicates (as passed through physical layer channel or signal) or whether is needed further monitoring additionally by wake-up signal instruction UE PDCCH.If UE determinations need further to monitor additional PDCCH, additional PDCCH and basis are read in time slot later The information of scheduling PDSCH or PUSCH on the additional PDCCH, dynamic rewrite PDSCH the or PUSCH resources of original SPS distribution Time-frequency location information..

Please refer to Fig.1 5, UE monitor wake-up signal 501, if in wake-up signal 501 instruction need rewrite PDSCH or The SPS scheduling informations time-frequency location of resource (i.e. SPS distribute) of PUSCH, then continue to monitor additional PDCCH 511, and according to The acquisition of information running time-frequency resource 522 of scheduling PDSCH or PUSCH in PDCCH 511 simultaneously decodes PDSCH or sends PUSCH.If Wake-up signal is not detected in running time-frequency resource 501 in UE, then continues that idle state is kept to need the wake-up monitored letter until next Number time-frequency location 502.If detect wake-up signal 502, and in wake-up signal 502 instruction without rewrite scheduling PDSCH or The information of PUSCH, the then time-frequency location that resource is directly distributed according to original SPS decode PDSCH 522.

In another example, whether the information of scheduling PDSCH or PUSCH needs dynamically to be rewritten, and is passed through by base station RRC information (such as SIB) is allocated to UE.If base station informs that UE needs dynamic to rewrite scheduling PDSCH or PUSCH by RRC information Information, then UE may not need monitoring wake-up signal, and directly detect PDCCH.This mode is considered falling (fall Back) mechanism.Falling mechanism has expanded flexibility of the present embodiment SPS approach applications in paging service.

For being used to page (Idle state), the SPS of DRX (connected state) or broadcast multi-broadcasting, activation can pass through RRC is configured and is pre-defined to realize, rather than is activated by DCI.For example, it is pre-defined, as long as base station configuration SPS's seeks Either DRX or MBMS/SC-PTM is exhaled, then then default activation SPS when UE receives information above.

6 are please referred to Fig.1, user equipment of the present embodiment another kind for semi-static resource scheduling includes：

Resource module is obtained, resource is distributed for obtaining SPS；

Wake-up module is detected, for detecting wake-up signal；

Channel module is decoded, if for successfully being detected the wake-up signal, is solved in acquired SPS distribution resources Code PDSCH sends PUSCH.

Obtain resource module, detection wake-up module and decode channel module the course of work correspond respectively to step 2001, 2002 and 2003, details are not described herein again.

Poewr control method introduced below, more specifically, the side that the setting of uplink maximum transmission power and power climb Method.For wireless communication system, being connect to uplink signal for other cell base stations is interfered in order to avoid UE transmission powers are excessive It receives, the UE maximum powers that can emit can be limited.Cell where 7, UE a01 reside in base station a03 is please referred to Fig.1, is The interference to facing cell base station a04, maximum transmission power is avoided to be limited.Such as, at this point, UE a02 use confined work( Rate emits up channel, and the signal strength that base station a04 is received at this time is a22, will not service UE to it and have an impact.Base station meeting Broadcast a maximum uplink transmission power P-max that can emit in this cell UE.Sending accidental access signal (such as NPRACH, PRACH) or Uplink Shared Channel (such as PUSCH, NPUSCH) or when uplink control channel (PUCCH), UE can be with The maximum transmission power of transmission is no more than the P-max by system broadcasts.However, in NB-IoT or eMTC systems, have UE is in indoor or basement, at this point, even if can emit maximum power transmission signal according to UE, from base station, letter Number intensity is still very weak.Such as UE a01, even if using maximum transmission power P_PowerClass, to persistent district and other cells It not will produce strong jamming.For this kind of UE, as other UE, it is unreasonable still to limit its maximum transmission power.Such as Fruit can allow the transmitting maximum power P that this kind of UE can try one's best_PowerClass, have very great help instead to the power consumption of UE.

Preferably, base station can at most configure the resource of 3 groups of NPRACH, and every group of resource corresponds to a kind of repetition of NPRACH time Number is respectively defined as enhancing covering grade (enhanced coverage level) 0,1,2.It is minimum for number of repetition One group of NPRACH resource (enhancing covering grade 0), its transmission power can be arranged according to RSRP measurement results in UE, and carries out Power climbs (power ramping).And maximum transmission power is then selected to carry out others enhancing covering grade The transmitting of NPRACH.Optionally, UE can also climb to other covering grades progress power.Wherein, maximum transmission power is The maximum power (P-max) and UE itself PA maximum transmission power abilities (P of system broadcasts_PowerClass) minimum value, i.e.,：

P_{CMAX_H,c}=MIN { P_EMAX,c,P_PowerClass,

Wherein P_EMAX,c, determined by the parameter P-max that base station configures.

It is arrived to allow these UE in poor covering grade (for example, enhancing covering grade 1,2) that maximum power can be emitted Its PA ability (P_PowerClass), it can be further introduced into power in enhancing covering grade 1 or enhancing covering grade 2 and climb.

8 are please referred to Fig.1, the method for present embodiment power control includes the following steps：

Step 3001：User equipment (UE) obtains residing enhancing covering grade；

Step 3002：According to the type of the enhancing covering grade, transmission power corresponding with the type is determined.

In one example, if in the first enhancing covering grade, it is the first power that maximum transmission power, which is arranged, Value；If in second of enhancing covering grade, it is the second performance number that maximum transmission power, which is arranged,.

Wherein, one at least the first performance number or the second performance number obtains or the second performance number for base station configuration It can be the maximum power value of UE self-abilities.In one example, base station can be optionally that each enhancing covering grade is matched Set a maximum transmission power.In another example, maximum transmission power can retransmit secondary according to NPDCCH maximums (Rmax) is counted to determine, such as the Rmax of base station configuration is more than a thresholding, then it is the second performance number that maximum transmission power, which is arranged,. Similar, since uplink and downlink channel may not have reciprocity, then when using the second performance number that can pass through up channel Number of repetition define, such as NPUSCH formats 1 or format 2 number of repetition.Specifically, second of enhancing covering grade The number of repetition of corresponding NPRACH is more than the number of repetition of the corresponding NPRACH of the first covering grade.

It is a in one example, if UE is in the first enhancing covering grade, according to RSRP and it is arranged first The starting transmission power of kind enhancing covering grade, and NPRACH signals are sent using the starting transmission power, if random access Request does not succeed, then is climbed using power, until the maximum power or maximum transmission times of base station configuration.If UE is in Second of enhancing covering grade, then being arranged enhances the starting targeting sequencing transmission power of covering grade at second increases for former The transmitting work(that the maximum transmission power or last time of strong covering grade are used when the first enhancing covering grade sends NPRACH Rate, or sent out according to the calculated transmission power of target received power of second of covering grade, and using the starting transmission power NPRACH signals are sent, if random access request does not succeed, are climbed using power, until second of enhancing covering grade Second performance number, such as itself PA maximum transmission power.It includes that UE sentences according to RSRP that wherein UE, which is in second of enhancing covering grade, It is disconnected further in second of enhancing covering grade, and due to reaching the maximum attempts of the first enhancing covering grade Rise to second of enhancing covering grade.In one example, for from low covering grade climb the high covering grade of value UE with And different methods is selected to be arranged according to the user that RSRP thresholdings judge and a second covering grade NPRACH resources is used to send The starting transmission power of second grade.

Further, whether need to carry out power in the second covering grade to climb and initial power can be matched by base station Set acquisition.

9 are please referred to Fig.1, a kind of schematic diagram of accidental access signal transmission power setting method is shown.UE judges its institute Locate covering grade, if UE is in the first covering grade, is arranged according to RSRP and is originated in rising for the first enhancing covering grade Power is sent, and NPRACH signals are sent using the starting transmission power.If not being properly received random access response RAR, It carries out power to climb, retransmits NPRACH signals, wherein transmission power maximum value is the maximum transmission power of base station configuration.Such as Fruit reaches maximum transmission times in the first covering grade, and UE continues to send using the NPRACH resources of second of covering grade NRPACH.If UE is in second of enhancing covering grade, according to the emission maximum of the base station configuration in the first covering grade The transmission power that power or last time are used when the first enhancing covering grade sends NPRACH is starting transmission power or root NPRACH is sent according to the calculated transmission power of the target received power of second of covering grade, and using the starting transmission power Signal carries out power and climbs if not being properly received random access response RAR, NPRACH signals is retransmitted, wherein sending out Penetrate the second performance number that power maximum value is UE itself PA maximum transmission power or base station configures.If UE is in the third enhancing Covering grade sends NPRACH signals using UE itself PA maximum transmission power or the second performance number.For being in enhancing covering The UE of grade 0, is climbed using power, and maximum UE transmission power is the maximum power (P-max) and UE itself of system broadcasts PA maximum transmission power abilities (P_PowerClass) minimum value, i.e.,：P_CMAX,CE0=MIN { P_EMAX,P_PowerClass}.Increase for being in The UE of strong covering grade 1, continues to climb using power, initial value be set as system broadcasts maximum power (P-max) and UE itself PA maximum transmission power abilities (P_PowerClass) minimum value, i.e.,：P_{CMAX, CE0}, when enhancing covering grade 1, most Big transmission power is its own PA maximum transmission power P_PowerClass(it is denoted as P_CMAX,CE1).In other words, UE can first judge be Whether system broadcasts a maximum power P_EMAX, and judge whether the maximum power P of the broadcast_EMAXIt is sent out less than UE itself PA maximums Penetrate work((P_PowerClass).If P_EMAX<P_PowerClass, then when enhancing covering grade 1, from P_EMAXContinue to climb directly using power To P_PowerClass.Other than due to RSRP using enhancing covering grade 1, it can also reach most in enhancing covering grade 0 because of UE Big number of attempt.At this point, the initial power of enhancing covering grade 2 could be provided as last time in the first enhancing covering grade hair Send the transmission power used when NPRACH.If there is also enhancing covering grade 2, enhances covering grade and use UE itself PA most Big transmitting work((P_PowerClass, i.e. P_CMAX,CE2) send targeting sequencing.

Figure 20 is please referred to, the schematic diagram of another accidental access signal transmission power setting method is shown.UE judges it The starting in the first enhancing covering grade is arranged according to RSRP if UE is in the first covering grade in residing covering grade Transmission power, and NPRACH signals are sent using the starting transmission power.If not being properly received random access response RAR, It then carries out power to climb, retransmits NPRACH signals, wherein transmission power maximum value is the maximum transmission power of base station configuration. If UE is in second of enhancing covering grade, NPRACH signals are sent using the maximum transmission power of the stations UE configuration.If UE is in the third enhancing covering grade, and the maximum transmission power according to the base station configuration in the first covering grade has been to originate Power is penetrated, and NPRACH signals are sent using the starting transmission power, if not being properly received random access response RAR, It carries out power to climb, retransmits NPRACH signals, wherein transmission power maximum value is UE itself PA maximum transmission power.

In another example, it for the UE in enhancing covering grade 0, is climbed using power, maximum UE emits work( Rate is the maximum power (P-max) and UE itself PA maximum transmission power abilities (P of system broadcasts_PowerClass) minimum value, I.e.：P_CMAX,CE0=MIN { P_EMAX,P_PowerClass}.For enhancing the UE of covering grade 1, does not support power to climb, continue to use P_CMAX,CE1=P_CMAX,CE0The transmission of targeting sequencing is carried out, and for enhancing the UE of covering grade 2, from P_CMAX,CE0Start, climbs always It is raised to UE itself PA emission maximum work((P_PowerClass, i.e. P_CMAX,CE2) send targeting sequencing.

For transmitting the NPUSCH of Msg3 on i-th of time slot, transmission power enhances covering grade k most according to corresponding Big transmission powerTo determine.More specifically, if the number of repetition of Msg3 be more than a thresholding, (such as 2), then Maximum transmission power corresponding to covering grade is enhanced using it, i.e.,[dBm], otherwise root According to its occupied bandwidth, and it is the transmission power P used to send NPRACH targeting sequencings_{O_PRE}And one matched by high level The power deviation Δ set_{PREAMBLE_Msg3}And the maximum transmission power of corresponding enhancing covering grade kTo determine. In one example,10log(M_NPUSCH(i)+P_{O_PRE}+ΔPREAMBLE_Msg3 +PL[dBm].Wherein MNPUSCHi is the impact factor of signal occupied bandwidth.PL is downlink path loss.The above-mentioned maximum for Msg3 Transmitting power setting method can be equally applicable to Msg3 re-transmissions and the HARQ-ACK information transmission of Msg4.And Msg3 or The calculating for the power headroom PHR (power head room) that other uplinks NPUSCH is carried, a reference value of power headroom is should The maximum transmission power value of the NPUSCH of transmission, that is, the PHR in Msg3 corresponds to the maximum transmission power of Msg3.

Transmission for other NPUSCH, uplink maximum power enhance the emission maximum of covering grade k according to its correspondence PowerTo determine.In addition, its maximum transmission power can be configured by base station, such as by configuring NPUSCH It is rewritten in the RRC signaling of transmission.Such as, the specific P-max parameters of a user can be introduced, which gives birth to upon configuration Effect.In one example, the parameter is only effective to the uplink NPUSCH channels of non-Msg3.In another example, match once changing It sets and comes into force, be then applicable in until IDLE states always.For the NPRACH transmission of NPDCCH triggerings, maximum transmission power can be still Serious existing configuration, or reconfigured according to its corresponding enhancing covering grade.After having sent NPRACH, emission maximum Power can be reconfigured according to the NPRCCH corresponding covering grades of NPRACH triggered, alternatively, continuing to reuse original connected state Maximum transmission power.

Figure 21 is please referred to, user equipment of the present embodiment for semi-static resource scheduling includes：

Transmission power determining module, for the type according to the enhancing covering grade, determination is corresponding with the type Maximum transmission power.

The course of work of covering grade acquisition module and transmission power determining module corresponds respectively to present embodiment The step 3001 of Poewr control method and 3002, details are not described herein again.

In conjunction with can be seen that compared with prior art to the detailed description of present embodiment above, this specific implementation Mode at least has technique effect beneficial below：

Scheduling DCI format load after first, SPS activation is less than the scheduling DCI format load of SPS activation, The power consumption of UE Monitor detections DCI is reduced, while reducing the down channel scheduling overhead of SPS, reduces service delay, significantly Improve the efficiency of the utilization of resources.

Second, the channel resource that directly instruction distribution is retransmitted for HARQ legacy datas when SPS scheduling methods being allowed to activate, energy It is enough adapted to the scene that big data quantity transmission and high-frequency retransmit when coverage condition is poor in NB-IoT, after avoiding SPS from activating again Secondary scheduling allocates resources to the down channel expense of HARQ legacy datas re-transmission, improves the overall performance of system.

Third is designed by the multiple combinations in the domain for being included to DCI format, i.e. DCI and is adjusted to configure SPS activation and dynamic The parameter of degree has expanded flexibility and the scalability of SPS scheduling.

4th, it provides a variety of re-transmission response modes and meets the SPS resource allocation requirements retransmitted to HARQ under different scenes, The expense for reducing HARQ Signalling exchanges improves the reliability of system.

5th, more long period SPS is introduced, and more long period SPS can be used for paging channel or DRX channels.Reduce Downlink signaling expense, and reduce UE power consumptions.

6th, by introducing second maximum transmission power, in other words, by first transmission power pair for removing configuration In the limitation of the maximum transmission power under coverage enhancement channel condition so that UE can carry out uplink with the transmission power of bigger The transmitting of channel or signal not only significantly reduces uplink expense, is significantly reduced to reduce unnecessary transmission time The power consumption of UE.
