Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communication technology, and in particular to an uplink transmission method, an uplink indication method and a device. Background Art

[0002] In each connection state discontinuous reception (CONNECTEDDRX, CDRX) cycle in the radio resource control connection state (RRC_CONNECTED), before the duration (onduration), the base station transmits an energy-saving signal (currently the 3rd generation partnership project (3GPP) has named the downlink control information (DownlinkControl Information, DCI) format of the energy-saving signal based on the physical downlink control channel (Physical Downlink Control Channel, PDCCH) as DCI format 3_0) to a terminal (such as user equipment (UserEquipment, UE)) or a group of UEs, and the UE detects the energy-saving signal at the corresponding time.

[0003] See also Figure 1 If the UE receives a power saving signal and the power saving signal instructs the UE to detect the PDCCH of onduration or instructs the UE to wake up, the UE detects the PDCCH or starts the onduration timer.

[0004] If the UE receives a power saving signal and the power saving signal instructs the UE not to detect the onduration PDCCH or instructs the UE to go to sleep, the UE does not detect the PDCCH or skips (does not start) the onduration timer.

[0005] In the current Release 15 (R15) protocol, the Channel State Information (CSI) report can only be performed during the CDRX active time, and the UE cannot report CSI outside the CDRX active time. If there is no service for a long time, the energy-saving signal instructs the UE not to monitor the PDCCH, the UE does not detect the PDCCH or skips (does not start) the onduraton timer. According to the R15 protocol, the UE cannot report CSI at this time, which may cause the UE beam or link failure. Summary of the invention

[0006] One purpose of an embodiment of the present invention is to provide an uplink transmission method, an uplink indication method and a device to solve the problem of beam or link failure caused by the UE being unable to report CSI when an energy-saving signal indicates that the UE does not monitor the PDCCH.

[0009] In a second aspect, an embodiment of the present invention further provides an uplink indication method, applied to a network device, comprising:

[0010] Send indication information, where the indication information is used to indicate whether the terminal sends SRS and / or reports CSI in the corresponding CDRX period when the terminal does not receive the energy-saving signal or receives the energy-saving signal indicating that the terminal does not monitor the PDCCH for a duration.

[0012] A processing module is used to determine whether to send SRS and / or perform CSI reporting in the corresponding CDRX period according to network side instructions or protocol agreements if the terminal does not receive the energy-saving signal, or the received energy-saving signal indicates that the terminal does not monitor the PDCCH for a duration.

[0013] In a fourth aspect, an embodiment of the present invention further provides a terminal, comprising: a memory, a processor, and a program stored in the memory and executable on the processor, wherein the program, when executed by the processor, implements the steps in the uplink transmission method described in the first aspect.

[0027] To facilitate understanding of the embodiments of the present invention, several technical points are introduced below:

[0028] (1) Discontinuous Reception (DRX) in the RRC idle (RRC_IDLE) state.

[0029] In a Long Term Evolution (LTE) or fifth generation mobile communication (5G) system, a UE in an RRC_IDLE state needs to detect a paging signal sent by a base station at a preconfigured time, and the process of detecting a paging signal is as follows:

[0030] Blindly detect the PDCCH corresponding to the Paging Radio Network Temporary Identifier (Paging-RNTI, P-RNTI). If the PDCCH is not detected, then end this detection; if the PDCCH is detected, further detect the Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) indicated by the PDCCH. If the detected PDSCH is not the paging signal of this UE, then end the detection; otherwise, the detected PDSCH is the paging signal of this user.

[0031] The UE in the RRC_IDLE state periodically detects paging signals, and the probability of receiving the paging signal belonging to the UE is relatively low. The power consumption of PDCCH and PDSCH detected each time is relatively large, which is not conducive to terminal power saving.

[0032] (2)DRX in RRC connected state.

[0033] The basic mechanism of DRX is to configure a DRX cycle for the UE in the RRC_CONNECTED state. The DRX cycle consists of "On Duration" and "Opportunity for DRX": During the "On Duration" time, the UE monitors and receives PDCCH (activation period); during the "Opportunity for DRX" time, the UE does not receive data on the downlink channel to save power consumption (sleep period).

[0034] from Figure 2 It can be seen that in the time domain, time is divided into continuous DRX cycles.

[0035] drxStartOffset specifies the starting subframe of the DRX cycle, and longDRX-Cycle specifies the number of subframes that a long DRX cycle occupies. Both parameters are determined by the longDRX-CycleStartOffset field. onDurationTimer specifies the number of consecutive subframes that need to monitor PDCCH from the starting subframe of the DRX cycle (i.e. the number of subframes that the activation period lasts).

[0036] In most cases, when a UE is scheduled and receives or sends data in a certain subframe, it is likely to continue to be scheduled in the next few subframes. If it has to wait until the next DRX cycle to receive or send these data, it will cause additional delays. In order to reduce such delays, the UE will continue to be in the active period after being scheduled, that is, it will continue to monitor the PDCCH during the configured activation period. Its implementation mechanism is: whenever the UE is scheduled to initially transmit data, a timer (drx-InactivityTimer) will be started (or restarted), and the UE will remain in the active state until the timer times out. drx-InactivityTimer specifies the number of consecutive subframes that the UE will continue to be in the active state after successfully decoding a PDCCH indicating the initial transmission of uplink (Uplink, UL) or downlink (Downlink, DL) user data. That is, whenever the UE has initial transmission data scheduled, the timer is restarted once.

[0037] In order to further save power consumption of blindly detecting paging signals or PDCCH under the above two types of DRX, the concepts of wake-up signal (WUS) and sleep signal (collectively referred to as power saving signal) are proposed.

[0038] (3) Energy saving signal in RRC_IDLE or RRC inactive (RRC_inactive) state:

[0039] In each paging cycle in the idle state, before a paging occasion (PO), the base station transmits a power-saving signal to the UE, and the UE detects the power-saving signal at a corresponding time.

[0040] If the energy-saving signal instructs the UE to detect the PDCCH at time PO, the UE detects the PDCCH;

[0041] If the energy-saving signal does not instruct the UE to detect the PDCCH at the PO time, the UE does not detect the PDCCH;

[0042] Optionally, detecting the energy-saving signal is less complex and more power-saving than blindly detecting the Paging signal or the PDCCH.

[0043] The energy-saving signal mentioned above may be a signal similar to PDCCH, or a sequence-related signal such as a channel state information reference signal (Channel State Indication-Reference Signals, CSI-RS), or an on-off keying (OOK) signal.

[0052] See also Figure 4 An embodiment of the present invention provides an uplink transmission method, the execution subject of the method is a terminal, and includes: step 401.

[0053] Step 401: If the terminal does not receive the energy-saving signal, or the received energy-saving signal indicates that the terminal does not monitor the PDCCH for a certain period of time, it determines whether to send SRS and / or report CSI in the corresponding CDRX period according to the network side instruction or protocol agreement.

[0054] Among them, whether to send SRS and / or whether to report CSI includes the following situations: (1) not sending SRS; (2) sending SRS; (3) reporting CSI; (4) not reporting CSI; (5) not sending SRS and reporting CSI; (6) sending SRS and reporting CSI; (7) not sending SRS and not reporting CSI; (8) sending SRS and not reporting CSI.

[0055] Optionally, the SRS may include: a semi-persistent sounding reference signal (Semi-Persistent SRS, SP-SRS) and / or a periodic sounding reference signal (Periodic SRS, P-SRS).

[0056] Optionally, CSI reporting can be extended to CSI reporting and / or CSI measurement, such as beam measurement. That is, if the terminal does not receive an energy-saving signal, or the received energy-saving signal indicates that the terminal does not monitor the PDCCH for a certain period of time, it is determined whether to perform CSI-RS or SSB measurement in the corresponding CDRX period according to the network side indication or protocol agreement.

[0057] Optionally, the CSI resources may include: non-zero power CSI reference signal (Non-Zero Power CSI-RS, NZP-CSI-RS) resources, and / or synchronization signal block (Synchronization Signal and PBCH block, SSB) resources.

[0058] Optionally, the CDRX cycle includes one of the following: (1) the duration of CDRX; (2) the active time of CDRX; (3) other times in the CDRX cycle except the duration of CDRX and / or the active time of CDRX, i.e. other moments of the CDRX cycle.

[0059] Optionally, the terminal does not receive a power-saving signal, or receives a power-saving signal and the power-saving signal indicates that the terminal does not monitor a physical downlink control channel PDCCH for a duration, specifically including:

[0060] At the monitoring occasion of the energy-saving signal, the terminal does not receive the energy-saving signal, or receives the energy-saving signal and the energy-saving signal indicates that the terminal does not monitor the PDCCH for a duration. The monitoring occasion refers to the time slot in which the energy-saving signal is sent, for example, specifically including the OFDM symbol for monitoring the energy-saving signal on the time slot.

[0061] In some embodiments, receiving indication information from a network side, and determining to execute a first behavior in a corresponding CDRX cycle according to the indication information;

[0062] The first behavior is one of the above-mentioned situations of whether to send SRS and / or whether to report CSI, including the following:

[0063] (1) Sending SRS and / or reporting CSI. In this way, when the UE skips the on duration or activation time, it still sends SRS and / or reports CSI within the CDRX period, such as onduration. This can avoid the impact of the UE not sending SRS and reporting CSI on beam or link management, and reduce the probability of UE beam or link failure.

[0064] (2) Not sending SRS and / or reporting CSI can avoid the impact of UE not reporting CSI on beam or link management, reduce the probability of UE beam or link failure, and reduce UE power consumption by reducing unnecessary SRS transmission;

[0065] (3) Sending SRS and / or not reporting CSI can avoid the impact on beam or link management caused by the UE not sending SRS, reduce the probability of UE beam or link failure, and reduce UE power consumption by reducing unnecessary CSI reporting;

[0066] (4) Do not send SRS and / or do not report CSI, thereby reducing unnecessary SRS and CSI reporting and reducing UE power consumption.

[0067] Optionally, the indication information indicates whether the terminal sends SRS and / or reports CSI in the corresponding CDRX period when no energy-saving signal is received, or when an energy-saving signal is received and the energy-saving signal indicates that the terminal does not monitor the PDCCH for a duration.

[0068] Optionally, the indication information may be Radio Resource Control (RRC) signaling or other signaling / information.

[0069] In the embodiment of the present invention, the terminal determines the behavior of the terminal through indication information, so that the terminal can send SRS and CSI reporting more flexibly and balance the conflict between terminal power consumption and beam link failure.

[0070] In some embodiments, the second behavior is performed in a corresponding CDRX cycle according to the protocol agreement;

[0071] The second behavior includes one of the following:

[0072] (1) Sending SRS and / or reporting CSI;

[0073] (2) Not sending SRS and / or reporting CSI;

[0074] (3) Sending SRS and / or not reporting CSI;

[0075] (4) Do not send SRS and / or do not report CSI.

[0076] Furthermore, if no instruction is received from the network side, the second behavior is performed in the corresponding CDRX cycle according to the protocol agreement.

[0077] In some embodiments, the indication information includes: CSI reporting configuration information, the CSI reporting configuration information (CSI-ReportConfig) includes one or more of the following: one or more CSI reporting quantities (reportQuantity) reported; one or more CSI reporting quantities not reported, wherein the CSI reporting quantity may indicate the type of CSI reporting quantity, such as channel state information reference signal resource indication-rank indication-precoding matrix indication-channel quality indication (CSI-RS Resource Indicator-Rank Indicator-Channel Quality Indicator, cri-RI-PMI-CQI), channel state information reference signal resource indication reference signal received power (CSI-RS Resource Indicator-Reference Signal Received Power, CRI-RSRP), etc.

[0078] Optionally, the CSI reporting amount includes one or more of the following:

[0079] (1) Channel state information reference signal resource indicator reference signal received power (CRI-RSRP);

[0080] (2) The reference signal received power of the synchronization signal block (ssb-Index-RSRP);

[0081] (3) channel state information reference signal resource indicator-rank indicator-precoding matrix indicator-channel quality indicator (cri-RI-PMI-CQI), i.e., a channel quality indicator corresponding to the channel state information reference signal resource indicator, rank indicator, and precoding matrix indicator;

[0082] (4) CSI-RI-i1, i.e., i1 corresponding to CSI-RI and rank indication;

[0083] (5) CSI-RI-i1-CQI, i.e., CSI corresponding to CSI-RI, rank indicator and i1;

[0084] (6) Channel State Information Reference Signal Resource Indicator-Rank Indicator-Channel Quality Indicator (cri-RI-CQI), i.e., a channel quality indicator corresponding to the channel state information reference signal resource indicator and the rank indicator;

[0085] (7) CSI-RS Resource Indicator-Rank Indicator-Level Indicator-Precoding Matrix Indicator-Channel Quality Indicator

[0086] Precoding Matrix Indicator-Channel Quality Indicator, cri-RI-LI-PMI-CQI), that is, the channel quality indicator corresponding to the channel state information reference signal resource indication, rank indication, layer indication, and precoding matrix indication.

[0087] Among them, the indication information may indicate that the terminal reports certain CSI reporting quantities, or indicates that the terminal does not report certain CSI reporting quantities, or indicates that the terminal reports certain CSI reporting quantities and does not report certain CSI reporting quantities. The specific indication method may include but is not limited to: a bitmap method, such as 1 bit corresponds to a CSI reporting quantity, and different values ​​of the bit indicate whether to report; a reporting list of CSI reporting quantities, in which all CSI reporting quantities in the list are reported, and all CSI reporting quantities not in the list are not reported; a non-reporting list of CSI reporting quantities, in which all CSI reporting quantities in the list are not reported, and all CSI reporting quantities not in the list are reported; when there are both a reporting list and a non-reporting list, whether the CSI reporting quantities that do not appear in the two lists are reported or not can be implemented based on the terminal, or all are reported by default, or none are reported by default.

[0088] For example, the UE performs CSI reporting with the CSI reporting amount of 'cri-RSRP' and / or 'ssb-Index-RSRP', and other types of CSI reporting amounts may not be reported; or the UE performs CSI reporting with the CSI reporting amount of 'cri-RI-PMI-CQI' and / or 'cri-RI-i1', and other types of CSI reporting amounts may not be reported; or the UE performs CSI reporting with the CSI reporting amount of 'cri-RI-i1-CQI' and / or 'cri-RI-CQ', and other types of CSI reporting amounts may not be reported.

[0089] It is worth pointing out that the above reported amounts are only for illustrative purposes, and other CSI reported amounts not listed are no longer listed one by one.

[0090] In this embodiment, when the terminal does not receive the energy-saving signal, or the energy-saving signal received by the terminal indicates that the terminal does not monitor the PDCCH for a certain period of time, the behavior of the terminal can be determined according to the network device indication or protocol agreement, which can make the terminal send SRS and CSI reports more flexible and balance the conflict between terminal power consumption and beam or link failure.

[0091] See also Figure 5 The embodiment of the present invention further provides an uplink indication method, the execution subject of the method is a network device, including: step 501.

[0092] Step 501: Send indication information, wherein the indication information is used to indicate whether the terminal sends SRS and / or reports CSI in the corresponding CDRX period when no energy-saving signal is received or the received energy-saving signal indicates that the terminal does not monitor the PDCCH for a duration.

[0094] For example, the network device sends first indication information to the terminal to indicate not to send the SRS, which can reduce unnecessary SRS sending and reduce power consumption of the terminal.

[0095] For example, the network device sends second indication information to the terminal to instruct the sending of SRS, which can avoid the impact on beam or link management caused by the UE not sending SRS for a long time, and reduce the probability of UE beam or link failure.

[0096] For example, the network device sends third indication information to the terminal to indicate not to report CSI, which can reduce unnecessary CSI reporting and reduce power consumption of the terminal.

[0097] For example, the network device sends the fourth indication information to the terminal to instruct CSI reporting, which can avoid the impact on beam or link management caused by the UE not reporting CSI for a long time, and reduce the probability of UE beam or link failure.

[0098] For example, the network device sends the fifth indication information to the terminal, which is used to indicate not to send SRS and perform CSI reporting. This can avoid the impact on beam or link management caused by the UE not reporting CSI for a long time, reduce the probability of UE beam or link failure, and at the same time reduce unnecessary SRS transmission and reduce UE power consumption.

[0099] For example, the network device sends the sixth indication information to the terminal to instruct the sending of SRS and CSI reporting, which can avoid the impact on beam or link management caused by the UE not reporting CSI and sending SRS for a long time, and reduce the probability of UE beam or link failure.

[0100] For example, the network device sends seventh indication information to the terminal, which is used to instruct not to send SRS and not to report CSI, thereby reducing unnecessary SRS sending and CSI reporting and reducing UE power consumption.

[0101] For example, the network device sends the eighth indication information to the terminal, which is used to instruct the sending of SRS and not to report CSI. This can avoid the impact on beam or link management caused by the UE not sending SRS for a long time, reduce the probability of UE beam or link failure, and reduce unnecessary CSI reporting, thereby reducing UE power consumption.

[0102] Optionally, the SRS may include: SP-SRS and / or P-SRS.

[0103] Optionally, the CDRX cycle includes one of the following: (1) the duration of CDRX; (2) the active time of CDRX; (3) other times in the CDRX cycle except the duration of CDRX and / or the active time of CDRX, i.e. other moments of the CDRX cycle.

[0104] Optionally, the terminal does not receive the energy-saving signal, or the received energy-saving signal indicates that the terminal does not monitor a physical downlink control channel PDCCH for a duration, specifically including:

[0105] At the monitoring moment of the energy-saving signal, the terminal does not receive the energy-saving signal, or the received energy-saving signal indicates that the terminal does not monitor the PDCCH for a duration.

[0106] In some embodiments, the configuration information of CSI reporting is sent to the terminal, and the configuration information of CSI reporting includes one or more of the following: one or more CSI reporting amounts reported; one or more CSI reporting amounts not reported;

[0107] Among them, the CSI reporting amount can indicate the type of CSI reporting amount, such as channel state information reference signal resource indication-rank indication-precoding matrix indication-channel quality indication, reference signal receiving power of channel state information reference signal resource indication, etc.

[0108] Optionally, the CSI reporting amount includes one or more of the following:

[0109] (1) Channel state information reference signal resource indicator reference signal received power (CRI-RSRP);

[0110] (2) The reference signal received power of the synchronization signal block (ssb-Index-RSRP);

[0111] (3) Channel state information reference signal resource indicator-rank indicator-precoding matrix indicator-channel quality indicator (cri-RI-PMI-CQI);

[0115] (7) Channel state information reference signal resource indication-rank indication-layer indication-precoding matrix indication-channel quality indication (cri-RI-LI-PMI-CQI).

[0116] In an embodiment of the present invention, the network device can instruct the terminal on the behavior of the terminal when no energy-saving signal is received, or the received energy-saving signal instructs the terminal not to monitor the PDCCH for a duration, which can make the terminal more flexible in sending SRS and CSI reporting and balance the conflict between terminal power consumption and beam or link failure.

[0117] The following combines Example 1 and Example 2 to describe how to determine whether to send a sounding reference signal SRS and / or report channel state information CSI in the corresponding connected state discontinuous reception CDRX period according to network side instructions or protocol agreements when the terminal does not receive a power-saving signal, or receives a power-saving signal and the power-saving signal indicates that the terminal does not monitor the PDCCH for a duration.

[0118] Example 1:

[0119] Step 1: The UE receives the RRC signaling sent by the network side, and the RRC signaling may indicate the following a or b;

[0120] a) RRC signaling instructs the UE that when no energy-saving signal is detected (the DCI format of the energy-saving signal is DCI format3_0), or when an energy-saving signal is received and the energy-saving signal instructs the UE not to monitor the PDCCH of onduration, during the corresponding CDRX onduration or CDRX active time (or at other times of the CDRX cycle), the UE reports CSI with a reporting amount of 'cri-RSRP' or 'ssb-Index-RSRP', and other types of reporting amounts are not reported.

[0121] b) RRC signaling instructs the UE not to send SRS during the corresponding CDRX onduration or CDRX active time (or other moments in the CDRX cycle) when no energy-saving signal (DCI format 3_0) is detected, or when an energy-saving signal is received and the energy-saving signal instructs the UE not to monitor the PDCCH onduration.

[0122] The CSI reporting period, CSI resources and the type of CSI reporting amount may be configured in advance through other RRC signaling.

[0123] Step 2: According to the RRC signaling, the UE does not send SRS and report CSI during the corresponding CDRX onduration or CDRX active time, where the content of the CSI report includes 'cri-RSRP' or 'ssb-Index-RSRP'.

[0124] In Example 1, the impact of the UE not reporting CSI on beam or link management can be avoided, the probability of UE beam or link failure is reduced, and unnecessary SRS transmission is reduced, thereby reducing UE power consumption.

[0125] Embodiment 2:
