Technical field

This application relates to the field of wireless communication technology, and in particular to a method and device for power-saving signal configuration and transmission.

Background technique

In the 5G NR system, in order to obtain downlink scheduling information, a terminal needs to monitor the PDCCH on each physical downlink control channel (PDCCH) monitoring opportunity (PDCCH monitoring occasion) to determine whether user scheduling information is transmitted. Among them, one PDCCH monitoring opportunity corresponds to a period of time, such as a period of several symbols. The process of PDCCH monitoring at a PDCCH monitoring opportunity is a PDCCH decoding process. According to the cyclic redundancy check (cyclic redundancy checking, CRC) check result, it is determined whether the PDCCH has transmitted downlink control information (downlink control information) carrying user scheduling information. control information, DCI). If the PDCCH transmits user scheduling information, the terminal can obtain a positive CRC check result and can obtain the scheduling information carried in the DCI; otherwise, if the CRC check result is a negative value, the terminal cannot obtain any information in the DCI.

When the terminal is configured with discontinuous reception (DRX), the terminal will discontinuously monitor the PDCCH. The terminal only performs PDCCH monitoring during the DRX activation period (DRX on-duration) or when the inactivity timer (inactivity timer) has not timed out to reduce terminal power consumption. The terminal can configure a long DRX cycle or a short DRX cycle, and can also configure a long DRX cycle and a short DRX cycle at the same time. Among them, the long DRX cycle may be an integer multiple of the short DRX cycle.

Before the activation period (on-duration) of the DRX cycle, the base station may send a power saving signal to the terminal to dynamically indicate whether the terminal should perform PDCCH monitoring during the activation period of one or more DRX cycles. The power saving signal is a PDCCH type physical layer signal, and its monitoring process is consistent with the PDCCH monitoring behavior scheduled by the user.

How to match the monitoring opportunity of the power saving signal with the activation period of the DRX when the terminal is configured with the long DRX cycle and the short DRX cycle at the same time is a problem that needs to be solved at present.

Detailed ways

The embodiment of the present application proposes a PDCCH-based physical layer transmission design solution of the power saving signal, which can be applied to monitor the power saving signal when the terminal is configured with a long DRX cycle and a short DRX cycle at the same time.

The following first briefly describes the configuration of the DRX mechanism and the PDCCH monitoring opportunity.

Fig. 1 exemplarily shows the DRX cycle. A DRX cycle includes a DRX active period (on-duration) and a DRX inactive period (DRX off, also called opportunity for DRX). In a DRX cycle, the terminal only monitors the PDCCH during the DRX active period (on-duration) period. During the DRX inactive period (opportunity for DRX), the terminal enters sleep mode and does not receive PDCCH in this mode to reduce power consumption .

DRX information (DRX-Info, namely DRX parameters) specifically includes the following items:

-DRX activation timer (drx-onDurationTimer): the duration of continuous monitoring of PDCCH from the DRX cycle;

-DRX slot offset (drx-SlotOffset): the time delay from the start of the DRX activation timer (drx-onDurationTimer);

-DRX-InactivityTimer (drx-InactivityTimer): When the PDCCH indicates a new uplink (UL) or downlink (DL) data transmission, it is started after the PDCCH is received. When the timer expires, the terminal will enter the inactive state ；

-DRX downlink retransmission timer (drx-RetransmissionTimerDL): For each downlink hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) process, the maximum duration before the downlink retransmission data arrives;

-DRX uplink retransmission timer (drx-RetransmissionTimerUL): For each uplink HARQ process, the maximum duration before the uplink retransmission data arrives;

-Long DRX cycle start offset (drx-LongCycleStartOffset): the position where the long DRX cycle starts;

-Long DRX cycle (drx-LongCycle): the cycle length of the long DRX, which is an integer multiple of the short DRX;

-Short DRX cycle (drx-ShortCycle): the length of the short DRX cycle, this parameter is optional;

-Short DRX cycle timer (drx-ShortCycleTimer): During the running of this timer, the terminal adopts the short DRX cycle, the value of which is an integer multiple of the short DRX, and this parameter is optional;

-DRX downlink HARQ RTT timer (drx-HARQ-RTT-TimerDL): For each downlink HARQ process, the media medium control (madia access control, MAC) entity needs to perform the minimum duration before downlink HARQ retransmission;

-DRX uplink HARQ RTT timer (drx-HARQ-RTT-TimerUL): For each uplink HARQ process, the MAC entity needs to perform the minimum duration before uplink HARQ retransmission.

When any one of DRX activation timer (drx-onDurationTimer), DRX inactivity timer (drx-InactivityTimer), DRX downlink retransmission timer (drx-RetransmissionTimerDL), DRX uplink retransmission timer (drx-RetransmissionTimerUL) is running , The terminals are all activated.

When the terminal is configured with a short DRX cycle and a long DRX cycle at the same time, if the terminal receives a MAC CE carrying a DRX command (ie DRX Command MAC CE, where CE is the English abbreviation of control element, which means control unit), or DRX When the inactivity timer (drx-InactivityTimer) expires, the terminal enters a short DRX cycle, and starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). When the short DRX cycle timer (drx-ShortCycleTimer) expires, the terminal enters the long DRX cycle. If new data arrives during the DRX activation period, the terminal starts or restarts the DRX inactivity timer (drx-InactivityTimer).

The PDCCH monitoring opportunity is configured through search space aggregation. A search space is composed of a set of candidate PDCCHs, and the terminal needs to blindly detect the PDCCH in the search space according to the desired DCI format (DCI format).

The configuration parameters of the search space of the PDCCH may include:

-Index of the search space collection, that is, search space ID;

-The control resource set number used to establish the connection between the search space s and the control resource set p, namely CORESET ID;

-PDCCH monitoring period k _p,s and offset value op _,s , the units of which are slots (slot), the terminal determines the time slot for monitoring the downlink control channel according to this configuration parameter;

-PDCCH monitoring pattern in the time slot;

-The number of PDCCH candidates (PDCCH candidates) included in each aggregation level in the search space

The supported aggregation levels include {1 2 4 8 16} and are configured through independent parameters;

-Flag searchspaceType used to distinguish whether the current search space is a public search space or a terminal-specific search space;

-PDCCH monitoring time window, that is, the number of consecutive time slots in the search space set.

The introduction of a power saving signal before the DRX activation period (on-duration) can dynamically instruct the terminal whether to perform PDCCH monitoring during the activation period of one or more DRX cycles. Power-saving signal is a physical layer signal of the PDCCH type, and its monitoring process is consistent with the PDCCH monitoring behavior scheduled by the user.

According to the above description, the PDCCH monitoring opportunity is periodic and has a fixed value, and it is possible to receive the PDCCH at each PDCCH monitoring opportunity. If the terminal is configured with a long DRX cycle and a short DRX cycle at the same time, the monitoring cycle of the power saving signal based on the PDCCH will be affected by the DRX cycle, and this impact includes:

(1) If the monitoring period of the power-saving signal based on PDCCH is configured according to the short DRX cycle, then the long DRX cycle will contain multiple PDCCH monitoring opportunities, that is, multiple monitoring of the power-saving signal will be performed in a long DRX cycle. This situation causes unnecessary power consumption of the terminal.

(2) If the monitoring period of the power-saving signal based on the PDCCH is configured according to the long DRX cycle, the short DRX cycle timer (drx-ShortCycleTimer) starts or restarts at different times, which will cause the terminal to perform long The time of DRX cycle monitoring is not fixed. The terminal monitors the power-saving signal according to the long DRX cycle, which will result in no monitoring opportunity of the power-saving signal before the activation period of the long DRX cycle (on-duration), or the monitoring opportunity of the power-saving signal is away from the long DRX cycle activation period (on-duration). duration) has a longer time interval.

In order to solve the above problems, the embodiment of the present application provides a physical layer transmission design scheme of a power saving signal based on PDCCH, which can be applied to the case where the terminal is configured with a long DRX cycle and a short DRX cycle at the same time, so that the terminal is in a short DRX cycle In the case of a long DRX cycle and a long DRX cycle, use different monitoring opportunities to monitor the power-saving signal to avoid the dynamic change of the short DRX cycle and the long DRX cycle, resulting in the time when the power-saving signal monitoring opportunity appears and the on-duration of the DRX cycle. The starting points conflict.

The following first describes some technical terms in the embodiments of the present application.

The "terminal" in the embodiments of this application, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a way to provide users with voice and/ Or devices with data connectivity, for example, handheld devices with wireless connectivity, vehicle-mounted devices, etc. At present, some examples of terminals are: mobile phones (mobile phones), tablets, notebook computers, palmtop computers, mobile internet devices (MID), wearable devices, virtual reality (VR) devices, and augmented reality (augmented reality, AR) equipment, wireless terminals in industrial control, wireless terminals in self-driving (self-driving), wireless terminals in remote medical surgery, and smart grid (smart grid) The wireless terminal in the transportation safety (transportation safety), the wireless terminal in the smart city (smart city), the wireless terminal in the smart home (smart home), etc.

The "base station" in the embodiment of this application may be a RAN node or a base station. RAN is the part of the network that connects the terminal to the wireless network. A RAN node (or device) is a node (or device) in a radio access network, and can also be called a base station. At present, some examples of RAN nodes are: gNB, transmission reception point (TRP), evolved Node B (evolved Node B, eNB), radio network controller (RNC), Node B (Node B) B, NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), base band unit (baseband unit) , BBU), or wireless fidelity (Wifi) access point (AP), etc. In addition, in a network structure, the RAN may include a centralized unit (CU) node and a distributed unit (DU) node.

It should be understood that the terms “first”, “second”, etc. in the embodiments of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, for example, it can be implemented in an order other than those given in the illustration or description of the embodiments of the present application.

In the embodiment of the present application, for the case where the terminal is configured with two DRX cycles, that is, the long DRX cycle and the short DRX cycle, the base station configures a search space set for the PDCCH-based power saving signal, which includes a listening period, which is equal to the short The DRX cycle or a value shorter than the long DRX cycle (for example, it can be the common divisor of the long DRX cycle or not the common divisor of the long DRX cycle). When the terminal is in a short DRX cycle, its monitoring opportunity for the power saving signal is a subset 1 of the monitoring opportunity corresponding to the monitoring period configured in the search space set. When the terminal is in the long DRX cycle, its monitoring opportunity for the power saving signal is a subset 2 of the monitoring opportunity corresponding to the monitoring period configured in the search space set. Subset 1 and Subset 2 are determined by the monitoring behavior of the terminal, and correspond to monitoring rule 1 and monitoring rule 2 of the terminal, respectively. The way the terminal monitors the power-saving signal is different from the conventional PDCCH monitoring method. It is no longer required to monitor the PDCCH at every monitoring opportunity, but according to the corresponding rule 1 or rule 2 according to the DRX cycle of the terminal. The principle of the monitoring of electrical signals is: when the terminal is in a short DRX cycle, the monitoring of power-saving signals is performed according to rule 1. When the terminal is in the long DRX cycle, it monitors the power saving signal according to rule 2.

Refer to FIG. 2, which is a schematic diagram of the configuration flow of the power saving signal provided in this embodiment of the application. As shown in the figure, the process can include:

S201: The base station configures the power saving signal search space configuration information, the first subset indication information and the second subset indication information.

Wherein, the value of the monitoring period is equal to the value of the short DRX period or the value shorter than the long DRX period (for example, it may be the common divisor of the long DRX period or not the common divisor of the long DRX period).

Optionally, the base station may reuse the conventional PDCCH search space set to configure the search space configuration information (ie, configuration parameters) of the power saving signal. Specifically, the base station may configure the PDCCH search space set, which includes the PDCCH monitoring period, and the value of the monitoring period is equal to the value of the short DRX period or a value shorter than the long DRX period (for example, it may be the common divisor of the long DRX period, It may not be the common divisor of the long DRX cycle).

The base station may also configure corresponding first subset indication information and second subset indication information for the short DRX cycle and the long DRX cycle, respectively. The first subset indication information is used to indicate the first subset of the monitoring opportunities corresponding to the monitoring period (that is, the monitoring period included in the power-saving signal search space configuration information), and the second subset indication information is used to indicate the foregoing The second subset of monitoring opportunities corresponding to the monitoring period. The first subset corresponds to the monitoring opportunity of the power saving signal when the terminal is in a short DRX cycle, and the second subset corresponds to the monitoring opportunity of the power saving signal when the terminal is in a long DRX cycle.

Wherein, the monitoring period included in the first subset is N-1 monitoring periods per interval in the foregoing monitoring period, where N is an integer and N≥0. The monitoring period included in the second subset is M-1 monitoring periods per interval in the above-mentioned monitoring period, M is an integer and M=K×m, m is an integer and m≥1, K is the long DRX cycle compared to the short The multiple of the DRX period.

Optionally, the value of the first subset indication information is N, and the value of the second subset indication information is M, so that by configuring the values of the first subset indication information and the second subset indication information, The monitoring rule 1 of the power saving signal used by the terminal in the short DRX cycle and the monitoring rule 2 of the power saving signal used in the long DRX cycle are configured to the terminal.

Among them, according to the above description, rule 1 can indicate: when the terminal is in a short DRX cycle, monitor the power saving signal every N listening cycles; rule 2 can indicate: when the terminal is in a long DRX cycle, every M listening cycles Perform a monitoring of the power saving signal. When N=0, it means that the terminal will not monitor the power-saving signal when it is in the short DRX cycle. When N>1, it means that the terminal will monitor the power-saving signal at intervals of N-1 short DRX cycles within the short DRX cycle. . Since M=K×m, m is an integer and m≥1, it means that when the terminal is in the long DRX cycle, it needs to monitor the power saving signal, where K is the multiple of the long DRX cycle compared to the short DRX cycle.

S202: The base station sends the power saving signal search space configuration information, the first subset indication information and the second subset indication information to the terminal.

Optionally, in this step, the base station may use high-layer signaling to send the first subset indication information and the second subset indication information to the terminal. The power saving signal search space configuration information can be configured in a conventional PDCCH search space configuration set.

The process shown in Figure 2 above may also include the following steps:

The base station determines the DRX cycle of the terminal according to the DRX configuration information and the data transmission situation of the terminal (that is, whether the DRX cycle of the terminal is a short DRX cycle or a long DRX cycle), and according to the DRX cycle of the terminal and the power saving Signal search space configuration information, and according to one of the first subset indication information and the second subset indication information, determine the monitoring opportunity of the power saving signal, and send the power saving signal according to the monitoring opportunity of the power saving signal.

For example, if the terminal is in the short DRX cycle, the base station determines the monitoring opportunity for the power saving signal according to the monitoring period configured in the power saving signal search space configuration information and the first subset indication information, and according to the power saving signal The monitor sends a power saving signal. If the terminal is in the long DRX cycle, the base station determines the monitoring opportunity of the power saving signal according to the monitoring period configured in the power saving signal search space configuration information and the second subset indication information, and sends the message according to the monitoring opportunity of the power saving signal. electric signal.

In the above-mentioned embodiment of the present application, although a monitoring period is configured for the power saving signal, the first subset indication information and the second subset indication information are configured for the short DRX cycle and the long DRX cycle respectively, so that the terminal is in the short During the DRX cycle, monitor the power-saving signal according to the listening opportunity corresponding to the first subset, and monitor the power-saving signal according to the listening opportunity corresponding to the second subset when the terminal is in the long DRX cycle, so that the terminal is configured with both the short DRX cycle and the long DRX cycle. In the case of the DRX cycle, the monitoring of the power-saving signal can be flexibly performed, which solves the problem of the time when the power-saving signal monitoring opportunity appears and the on-duration of the DRX cycle due to the dynamic changes of the short DRX cycle and the long DRX cycle. The starting point does not match the problem. It can be embodied in the following two aspects:

First, in the conventional solution, if the monitoring period of the power saving signal based on the PDCCH is configured according to the short DRX cycle, the long DRX cycle includes multiple PDCCH monitoring opportunities, that is, multiple power saving will be performed in a long DRX cycle Signal monitoring, this situation causes unnecessary power consumption of the terminal. However, according to the above-mentioned embodiment of the present application, the monitoring opportunity corresponding to the second subset indicated by the second subset indication information is used in the long DRX cycle to monitor the power-saving signal, and the second subset is a subset of the short DRX monitoring cycle. For example, monitor the power-saving signal at intervals of multiple short DRX cycles, where the length of multiple short DRX cycles is equal to one long DRX period, so that the power-saving signal included in the long DRX cycle has less monitoring opportunities than PDCCH monitoring Opportunities, so compared to the above-mentioned conventional solutions, it can reduce unnecessary power consumption of the terminal.

In the second aspect, in the conventional solution, if the monitoring period of the power saving signal based on the PDCCH is configured according to the long DRX cycle, since the data arrival is bursty, the DRX inactivity timer (drx-InactivityTimer) is started after the data arrives. After the timer expires, the short DRX cycle timer (drx-ShortCycleTimer) is started or restarted, so that the time for starting or restarting the drx-ShortCycleTimer is not fixed. When the short DRX cycle timer (drx-ShortCycleTimer) expires, the terminal enters the long The DRX cycle, in turn, causes the terminal to monitor the power-saving signal and the start point of the active period of the long DRX cycle does not match. In this way, the terminal monitors the power-saving signal according to the long DRX cycle, which results in that there may be no monitoring opportunity for the power-saving signal before the on-duration of the long DRX cycle, or the monitoring opportunity of the power-saving signal is longer than the active period of the DRX cycle The (on-duration) time interval is longer. However, with the above-mentioned embodiments of the present application, the terminal does not always monitor the power-saving signal according to the long DRX cycle, but monitors the power-saving signal according to the listening opportunity corresponding to the first subset in the short DRX cycle, and according to the first subset in the long DRX cycle. The monitoring opportunity corresponding to the second subset monitors the power saving signal. The monitoring period of the power saving signal corresponding to the first subset may be several times the short DRX monitoring period, and the monitoring period of the power saving signal corresponding to the second subset may be several times the long DRX monitoring period, compared to In the above conventional solution, when the terminal is in the long DRX cycle, the terminal monitors the power saving signal according to the monitoring opportunity related to the long DRX cycle, which can ensure that the power saving signal can be received before the activation period of each long DRX cycle, and can also avoid power saving The time interval between the on-duration of the long DRX cycle and the long DRX cycle of the signal monitoring opportunity can increase the possibility of receiving the power saving signal and reduce unnecessary power consumption of the terminal.

Optionally, in some embodiments, the power saving signal search space configuration information may further include the first listening opportunity offset offset_1 and the second listening opportunity offset offset_2, which correspond to a short DRX cycle and a long DRX cycle, respectively. The first listening opportunity offset offset_1 is the listening opportunity offset of the power saving signal used when the terminal is in a short DRX cycle, and the second listening opportunity offset_2 is the listening opportunity offset of the power saving signal used when the terminal is in a long DRX cycle. That is, when the terminal is in the short DRX cycle, the offset for monitoring the power saving signal is offset_1 of the first listening opportunity, and when the terminal is in the long DRX cycle, the offset of monitoring the power saving signal is offset_2 of the second listening opportunity . For the short DRX cycle and the long DRX cycle, different monitoring opportunity offsets can be configured, and the monitoring opportunities of the power saving signal can be configured more flexibly according to the monitoring complexity and reliability of the power saving signal required by different DRX cycles.

Optionally, the unit of the first listening opportunity offset offset_1 and the second listening opportunity offset offset_2 may be a time slot. For example, using a time slot as a unit, according to the first listening opportunity offset offset_1, it can be determined in the short DRX cycle period. The starting position of the monitoring opportunity of the electrical signal can be determined according to the second monitoring opportunity offset_2 in the long DRX cycle.

Optionally, the units of the first listening opportunity offset offset_1 and the second listening opportunity offset offset_2 may be time slots. For example, using time slots as a unit, the first listening opportunity offset needs to satisfy the following relationship:

o _s-DRX mod(k _s-shortDRX )-offset_1=offset_short

Among them, O _s-DRX is the start offset of the long DRX cycle, k _s-shortDRX is the short DRX cycle, Amod(B) represents the mode operation modulo B on the value of A, offset_1 is the first listening opportunity offset, and offset_short is The time interval between the power saving signal and the short DRX cycle is configured by higher layer signaling. The offset of the second listening opportunity needs to satisfy the following relationship:

o _s-DRX -offset_2=offset_long

Among them, O _s-DRX is the start offset of the long DRX cycle, offset_2 is the second listening opportunity offset, and offset_long is the time interval between the power saving signal and the long DRX cycle, which is configured by high-level signaling.

Optionally, the values of the first listening opportunity offset offset_1 and the second listening opportunity offset offset_2 may be the same or different.

Optionally, the first listening opportunity offset can be configured in multiple ways. For example, it can be configured in any of the following ways:

Configuration method 1: Display the indication through the search space configuration information, that is, display the indication through the listening opportunity offset indication information in the search space configuration information;

Configuration method 2: Indicated by the interval value configured by high-layer signaling, the interval value is the interval value from the start point of the DRX activation period; specifically, the interval value from the start point of the DRX activation period can be configured through high-layer signaling, The offset of the first listening opportunity can be determined according to the interval value;

Configuration method 3: Indicated by the interval range configured by the search space or high-level signaling, the interval range is the interval range from the start point of the DRX activation period; specifically, the distance DRX activation period can be configured through the search space or high-level signaling The interval range of the starting point, the offset of the first listening opportunity can be determined according to the interval value;

Configuration method 4: It is indicated by the monitoring offset value configured within the interval range configured by the search space or high-level signaling, the interval range is the interval range from the start point of the DRX activation period; specifically, the search space or high-level signaling The signaling configures the listening offset value within the interval range from the start point of the DRX activation period, and the first listening opportunity offset can be determined according to the listening offset value configured within the interval range.

Optionally, the second listening opportunity offset can also be configured in multiple ways. For example, the configuration method adopted can be similar to any of the above-mentioned first listening opportunity offset configuration methods. No more details.

Optionally, in some embodiments, the power saving signal search space configuration information may further include a first monitoring time window duration_1 and a second monitoring time window duration_2, which correspond to the short DRX cycle and the long DRX cycle, respectively, and are used to indicate continuous The length of time to monitor the power saving signal. For short DRX cycle and long DRX cycle, different monitoring time windows can be configured, which can configure the monitoring opportunities of power saving signals more flexibly. The time window can be configured according to needs during specific implementation, so as to take into account the reliability of power saving signal transmission. And the effective use of system resources.

Specifically, the first listening time window duration_1 is the time slot length for the terminal to continuously monitor the power saving signal before the DRX activation period when the terminal is in the short DRX cycle, and the second listening time window duration_2 is the time slot length for the terminal to continuously monitor the power saving signal before the DRX activation period when the terminal is in the long DRX cycle The length of the time slot for monitoring the power saving signal. That is, when the terminal is in the short DRX cycle, the continuous duration of monitoring the power saving signal before the on-duration of the short DRX cycle is duration_1. When the terminal is in the long DRX cycle, during the on-duration of the long DRX cycle, -duration) The continuous duration of monitoring the power saving signal before is duration_2. Among them, the values of duration_1 and duration_2 may be the number of time slots.

Optionally, the values of the first monitoring time window duration_1 and the second monitoring time window duration_2 may be the same or different.

Optionally, in some embodiments of the present application, the power saving signal search space configuration information may further include the first control resource set CORESET_1 and the second control resource set CORESET_2 associated with the search space, corresponding to the short DRX cycle and Long DRX cycle. For short DRX cycle and long DRX cycle, different control resource sets can be configured, which can configure the time-frequency resources used by power-saving signals more flexibly. The control resource set can be configured as needed during specific implementation, so that power-saving signals can be taken into account. Reliability of transmission and effective use of system resources.

Among them, the first control resource set CORESET_1 is the resource occupied by the power-saving signal during the short DRX cycle, which can include time domain resources or frequency domain resources, or both frequency domain resources and time domain resources; the second control resource set CORESET_2 is long The resources occupied by the power saving signal in the DRX cycle may include time domain resources or frequency domain resources, or may include both frequency domain resources and time domain resources.

Optionally, the first control resource set CORESET_1 and the second control resource set CORESET_2 may be the same resource set, or may be different resource sets.

Optionally, in some embodiments, the power saving signal search space configuration information further includes a first power saving signal monitoring pattern pattern_1 and a second power saving signal monitoring pattern pattern_2, which correspond to a short DRX cycle and a long DRX cycle, respectively. That is, the first battery-saving signal monitoring pattern pattern_1 is a battery-saving signal monitoring pattern used when the terminal is in a short DRX cycle, and the second battery-saving signal monitoring pattern pattern_2 is a battery-saving signal monitoring pattern used when the terminal is in a long DRX cycle. For short DRX cycle and long DRX cycle, different power-saving signal monitoring patterns can be configured, which can configure the time domain resources used by power-saving signals more flexibly, and the power-saving signal monitoring patterns can be configured according to the needs during specific implementation. Consider the reliability of power-saving signal transmission and the effective use of system resources.

Among them, the power-saving signal monitoring pattern can be used to indicate the time domain resources occupied by the power-saving signal, for example, it can indicate the start symbol of the power-saving signal in a time slot and the number of symbols continuously transmitted from the start symbol.

Optionally, the first power saving signal monitoring pattern pattern_1 and the second power saving signal monitoring pattern pattern_2 may be the same or different.

It should be noted that the foregoing embodiments on the base station side can be used independently or can be combined arbitrarily, which is not limited in this application.

For example, the power saving signal search space configuration information configured by the base station includes a monitoring period. In addition, one or more of the following information (parameters) may be included:

-Listening opportunity offset, the number of listening opportunity offset parameters can be one or two (for two cases, refer to the foregoing embodiment). If the number of listening opportunity offset parameters is one, the terminal is in the short DRX cycle Use the same listening opportunity offset parameter as the long DRX cycle;

-Monitoring time window, the number of monitoring time window parameters can be one or two (refer to the foregoing embodiment for the case of two).

-Monitoring patterns, the number of monitoring patterns can be one or two (refer to the previous embodiment for the case of two). If the number of monitoring patterns is one, the terminal uses the same one in the short DRX cycle and the long DRX cycle Monitor the pattern.

It should be noted that the foregoing only exemplarily enumerates several possible situations, and the embodiments of the present application are not limited to the foregoing enumerated situations.

It should be noted that the configuration of the power saving signal search space configuration parameters can be realized by extending the PDCCH search space configuration parameters or multiplexing the PDCCH search space configuration parameters. The configuration of the power saving signal search space configuration parameters can also be performed independently of the PDCCH search space configuration process.

The terminal receives the power saving signal search space configuration information and the first subset indication information and the second subset indication information sent by the receiving station, and monitors the power saving signal and PDCCH according to the above configuration information.

Refer to FIG. 3, which is a schematic diagram of a flow of receiving a power saving signal according to an embodiment of this application. The flow may include:

S301: The terminal receives the power saving signal search space configuration information and the first subset indication information and the second subset indication information sent by the base station.

Repeat again.

Optionally, according to different configuration modes of the first listening opportunity offset, a corresponding manner may be adopted to determine the first listening opportunity offset. For example, the determination method can include any method:

Determination method 1: Determine according to the search space configuration information. For example, if the first listening opportunity offset is indicated by the listening opportunity offset indication information in the search space configuration information, the terminal can determine the first listening opportunity according to the indication information Offset

Determination method 2: Determine according to the interval value configured by the higher layer signaling, the interval value is the interval value from the start point of the DRX activation period; for example, if the interval value from the start point of the DRX activation period is configured through the higher layer signaling, then The terminal can determine the first listening opportunity offset according to the interval value;

Determination method 4: Determine according to the monitoring offset value configured in the interval range configured by the search space or high-level signaling, the interval range is the interval range from the start point of the DRX activation period; for example, if the search space or high-level signaling is used If the monitoring offset value within the interval range from the start point of the DRX activation period is configured, the terminal can determine the first monitoring opportunity offset according to the monitoring offset value configured within the interval range.

Optionally, the second listening opportunity offset may also be determined in multiple ways. For example, the determination method adopted may be similar to any of the above-mentioned first listening opportunity offset determination methods. No more details.

Optionally, the terminal monitoring the power saving signal according to the power saving signal search space configuration information may include: when the terminal is in a short DRX cycle, shifting the corresponding position monitoring section according to the first monitoring opportunity Electrical signal, or continuously monitor the power saving signal within the first listening opportunity offset range corresponding to the first listening opportunity offset, or configure according to the first listening opportunity offset range corresponding to the first listening opportunity offset The offset value monitors the power saving signal. When the terminal is in the long DRX cycle, monitor the power saving signal according to the position corresponding to the second listening opportunity offset, or continuously monitor the power saving within the second listening opportunity offset range corresponding to the second listening opportunity offset Signal, or monitor the power-saving signal according to the offset value configured within the second listening opportunity offset range corresponding to the second listening opportunity offset.

Optionally, if the power-saving signal search space configuration information includes the first monitoring time window duration_1 and the second monitoring time window duration_2, when the terminal is in the short DRX cycle, the first monitoring time window duration_1 is used to activate the short DRX cycle The power saving signal is monitored in the corresponding length of time before the period; when the terminal is in the long DRX cycle, according to the second monitoring time window duration_2, the power saving signal is monitored in the corresponding length of time before the activation period of the long DRX cycle.

Optionally, if the power-saving signal search space configuration information includes the first power-saving signal monitoring pattern pattern_1 and the second power-saving signal monitoring pattern pattern_2, then when the terminal is in the short DRX cycle, the process is performed according to the first power-saving signal monitoring pattern pattern_1 Power-saving signal monitoring; when the terminal is in a long DRX cycle, it performs power-saving signal monitoring according to the second power-saving signal monitoring pattern pattern_2.

The implementation process of the foregoing embodiments of the present application will be described in detail below through several specific examples.

Example one

Example 1 is described by taking as an example the monitoring opportunities corresponding to the short DRX cycle and the long DRX cycle are the subset 1 of the power saving signal search space and the subset 2 of the node signal search space.

According to the process shown in FIG. 2, the process of configuring the power saving signal search space and the first subset indication information and the second subset indication information may include:

The base station uses high-level signaling to configure the parameters of the search space for the terminal to send the power saving signal. Taking the power saving signal based on the PDCCH as an example, the format of the parameter configuration is similar to the parameter configuration of the conventional PDCCH search space. Among them, the monitoring period is The value is the period length of the short DRX cycle or a value shorter than the long DRX cycle. For the short DRX cycle and the long DRX cycle, the monitoring offset value of the power saving signal is offset.

In addition, the base station also configures the relevant parameters of the power-saving signal monitoring behavior for the terminal through high-level signaling, including: the monitoring duration related parameter N (N is an integer and N≥ 0) when the terminal is in a short DRX cycle, and the terminal is in a long DRX cycle The monitoring duration related parameter M (M is an integer and M=K×m, m is an integer and m≥1, K is a multiple of the long DRX cycle compared to the short DRX cycle). The meanings of M and N are: when the terminal is in a short DRX cycle, it monitors the power-saving signal every N listening cycles, and when the terminal is in a long DRX cycle, it monitors the power-saving signal every M listening cycles. The monitoring position of the power saving signal is determined according to the offset value offset configured by the higher layer signaling. If the long DRX cycle is 4 times the short DRX cycle, take N=2, M=4 as an example, that is, when the terminal is in the short DRX cycle, the power-saving signal is monitored every 2 monitoring cycles, and when the terminal is in the long DRX cycle , Monitor the power-saving signal every 4 monitoring cycles, that is, monitor the power-saving signal once every long DRX cycle.

According to the configuration of the power-saving signal search space and the transmission of terminal data, the base station sends the power-saving signal, which may include:

The base station can learn the DRX cycle of the terminal according to the DRX parameter configuration and the data arrival situation of the terminal, that is, whether it is in the long DRX cycle or the short DRX cycle, and configure the parameters according to the current DRX cycle of the terminal and the power saving signal search space , The first subset indication information (parameter N) and the second subset indication information (parameter M), determine the monitoring opportunities of the power saving signal (such as the start position of monitoring the power saving signal and the duration of continuous monitoring of the power saving signal), and At the monitoring opportunity of the power-saving signal, the power-saving signal is sent to indicate whether the terminal wakes up from the sleep state in the subsequent DRX cycle to monitor the PDCCH or continue to sleep.

For example, if the current terminal is in a short DRX cycle, that is, when the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the base station sends a power-saving signal every 2 listening periods in the short DRX cycle that needs to be indicated. The monitoring offset value of a short DRX cycle is offset. If the current terminal enters a long DRX cycle, the base station sends a power-saving signal every 4 listening cycles in the long DRX cycle that needs to be indicated, and the power-saving signal is located at the position corresponding to the listening offset value offset of the first long DRX cycle. If the power-saving signal has an implicit indication function, that is, if the power-saving signal is not sent at the monitoring opportunity of the power-saving signal, it means that the terminal continues to sleep and does not enter the active state for DRX. At this time, the base station may not always be at the monitoring opportunity of the terminal The terminal sends a power saving signal. If the power saving signal carries explicit indication information, the base station will send the power saving signal to the terminal at the time when the terminal is listening.

According to the process shown in Figure 3, when the terminal is configured with a long DRX cycle and a short DRX cycle, the terminal monitors the power saving signal according to the following rules:

If the terminal receives the MAC CE carrying the DRX command, the DRX is turned on. At this time, the terminal enters the short DRX cycle, and starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). At this time, the terminal monitors the power-saving signal at the position corresponding to the monitoring offset value offset of the first short DRX cycle when receiving the MAC CE carrying the DRX command according to the monitoring parameters configured by the high-level signaling of the base station.

In the short DRX cycle, the terminal only monitors the PDCCH during the activation period. Whenever the terminal receives a DCI with a new data indication, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal adopts a short DRX cycle. During the short DRX cycle of the terminal, the terminal chooses to monitor the power saving signal every two monitoring cycles, and each monitoring opportunity is located at the monitoring offset value of the first short DRX cycle The position corresponding to offset.

When the short DRX cycle timer (drx-ShortCycleTimer) or the MAC CE carrying the long DRX command sent by the base station is received, the terminal enters the long DRX cycle. When the terminal enters the long DRX cycle, the terminal monitors the power saving signal every 4 listening cycles, and each listening opportunity is located at the position corresponding to the listening offset value offset of the long DRX cycle.

When the terminal receives the DCI with the new data indication during the long DRX activation period, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal is in a short DRX cycle. During the short DRX cycle of the terminal, the terminal monitors the power-saving signal every two listening cycles, and each listening opportunity is located at the position corresponding to the listening offset value offset of the first short DRX cycle.

When the terminal is in the short DRX cycle and the short DRX cycle timer (drx-ShortCycleTimer) does not expire, if the terminal receives the MAC CE with the long DRX command sent by the base station, the terminal enters the long DRX cycle. At this time, the terminal will receive the power-saving signal at the position corresponding to the monitoring offset value of the first DRX cycle after receiving the MAC CE, and then monitor the power-saving signal every 4 monitoring cycles.

Further, the terminal monitors the power-saving signal at the monitoring opportunity of the power-saving signal before the onduration of the DRX cycle, and performs subsequent DRX monitoring actions based on the monitoring of the power-saving signal. For example, if the terminal receives the power saving signal at the monitoring opportunity of the power saving signal, it enters the active state for PDCCH monitoring during the subsequent DRX activation period; otherwise, the terminal continues to be in the inactive state during the subsequent DRX activation period. The above-mentioned monitoring action of candidate DRX is only taken as an example, and the embodiment of the present application is not limited to performing other processing operations.

Example two

Example 2 is described by taking the short DRX cycle and the long DRX cycle respectively corresponding to the offset values of two listening opportunities.

The base station uses high-level signaling to configure the parameters of the search space for the terminal to send the power saving signal. Taking the power saving signal based on the PDCCH as an example, the format of the parameter configuration is similar to the parameter configuration of the conventional PDCCH search space. Among them, the monitoring period is The value is the period length of the short DRX cycle or a value shorter than the long DRX cycle.

In addition, the base station also configures related parameters of the power-saving signal monitoring behavior for the terminal through high-level signaling. The parameters may include: monitoring duration related parameters N (N is an integer and N≥0) when the terminal is in a short DRX cycle. The monitoring duration related parameter M in the long DRX cycle (M is an integer and M=K×m, m is an integer and m≥1, and K is a multiple of the long DRX cycle compared to the short DRX cycle). The meanings of M and N are: when the terminal is in a short DRX cycle, it monitors the power saving signal every N monitoring cycles, and when it is in a long DRX cycle, it monitors the power saving signal every M monitoring cycles. If the long DRX cycle is 4 times the short DRX cycle, take N=2, M=4 as an example, that is, when the terminal is in the short DRX cycle, the power-saving signal is monitored every 2 monitoring cycles, and when the terminal is in the long DRX cycle , Monitor the power-saving signal every 4 monitor cycles, that is, monitor once every long DRX cycle.

The base station can configure two listening opportunity offset values offset_1 and offset_2, which correspond to a short DRX cycle and a long DRX cycle, respectively. The two monitoring offset values can be the same or different. The same situation is the same as in Example 1. For different situations, the start position of the monitoring opportunity in the short DRX cycle is determined according to the offset value offset_1, and the start position of the monitoring activation in the long DRX cycle is determined according to the offset value offset_2. If the long DRX cycle requires a high delay in processing the power saving signal, offset_2 is greater than offset_1. Other parameters are similar to the parameter configuration of the conventional PDCCH search space set, and will not be repeated here.

The base station can learn the DRX cycle of the terminal according to the DRX parameter configuration and the data arrival situation of the UE, that is, whether it is in a long DRX cycle or a short DRX cycle. And according to the current DRX cycle of the terminal and the power saving signal search space configuration parameters, the first subset indication information (parameter N) and the second subset indication information (parameter M), the monitoring opportunity of the power saving signal (such as section The monitoring start position of the electrical signal and the duration of continuously monitoring the power-saving signal), and the power-saving signal is sent at the monitoring opportunity of the power-saving signal to indicate whether the terminal wakes up from the sleep state to monitor the PDCCH or continues to sleep in the subsequent DRX cycle.

For example, if the current terminal is in a short DRX cycle, that is, when the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the base station sends a power-saving signal every 2 listening periods in the short DRX cycle that needs to be indicated. The position corresponding to the monitoring offset value offset_1 of a short DRX cycle. If the current terminal enters a long DRX cycle, the base station sends a power-saving signal every 4 monitoring cycles of the long DRX that needs to be indicated, and the power-saving signal is located at the monitoring offset value offset_2 of the first long DRX cycle. If the power-saving signal has an implicit indication function, that is, if the power-saving signal is not sent at the monitoring opportunity of the power-saving signal, it means that the terminal continues to sleep and does not enter the active state for DRX. At this time, the base station may not always be at the monitoring opportunity of the terminal The terminal sends a power saving signal. If the power saving signal carries explicit indication information, the base station will send the power saving signal to the terminal at the time when the terminal is listening.

According to the process shown in Figure 3, when the terminal is configured with long DRX and short DRX, the terminal monitors the power saving signal according to the following rules:

If the terminal receives the MAC CE carrying the DRX command, the DRX is turned on. At this time, the terminal enters the short DRX cycle, and starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). At this time, the terminal monitors the power saving signal at the position corresponding to the monitoring offset value offset_1 of the first short DRX cycle when receiving the MAC CE carrying the DRX command according to the monitoring parameters configured by the high-level signaling of the base station.

In the short DRX cycle, the terminal only monitors the PDCCH during the activation period. Whenever the terminal receives a DCI with a new data indication, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal adopts a short DRX cycle. During the short DRX cycle of the terminal, the terminal chooses to monitor the power saving signal every two monitoring cycles, and each monitoring opportunity is located at the monitoring offset value of the first short DRX cycle The position corresponding to offset_1.

When the short DRX cycle timer (drx-ShortCycleTimer) times out or receives a MAC CE carrying a long DRX command sent by the base station, the terminal enters the long DRX cycle. When the terminal enters the long DRX cycle, the terminal monitors the power-saving signal every 4 monitoring cycles, and each monitoring opportunity is located at the position corresponding to the monitoring offset value offset_2 of the long DRX cycle.

When the terminal receives the DCI with the new data indication during the long DRX activation period, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal is in a short DRX cycle. During the short DRX cycle, the terminal monitors the power-saving signal once every two listening cycles, and each listening opportunity is located at the position corresponding to the listening offset value offset_1 of the first short DRX cycle.

When the terminal is in the short DRX cycle and the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the terminal enters the long DRX cycle when it receives the MAC CE with the long DRX command sent by the base station. At this time, the terminal receives the power-saving signal at the position corresponding to the monitoring offset value offset_2 of the first long DRX cycle after receiving the MAC CE, and then monitors the power-saving signal every 4 monitoring cycles.

Example three

In Example 3, a short DRX cycle and a long DRX cycle respectively correspond to one monitoring time window.

The base station uses high-level signaling to configure the parameters of the search space for the terminal to send the power saving signal. Taking the power saving signal based on the PDCCH as an example, the format of the parameter configuration is similar to the parameter configuration of the conventional PDCCH search space. Among them, the monitoring period is The value is the period length of the short DRX or a value shorter than the long DRX period.

In addition, the base station also configures the relevant parameters of the power-saving signal monitoring behavior for the terminal through high-level signaling: the monitoring duration related parameter N (N is an integer and N≥0) when the terminal is in short DRX, and the monitoring duration when the terminal is in long DRX is related Parameter M (M is an integer and M=K×m, m is an integer and m≥1, K is a multiple of the long DRX cycle compared to the short DRX cycle). The meanings of M and N are: when the terminal is in a short DRX cycle, it monitors the power saving signal every N monitoring cycles, and when it is in a long DRX cycle, it monitors the power saving signal every M monitoring cycles. If the long DRX cycle is 4 times the short DRX cycle, this embodiment takes N=2 and M=4 as an example for description, that is, when the terminal is in the short DRX cycle, the power saving signal is monitored every 2 monitoring cycles, and the terminal When in the long DRX cycle, the power saving signal is monitored every 4 monitoring cycles, that is, it is monitored once every long DRX cycle.

The base station can configure two monitoring time windows duration_1 and duration_2 for monitoring opportunities, which correspond to the number of time slots for continuously monitoring the power saving signal in the short DRX cycle and the long DRX cycle, respectively. The monitoring time window of the power saving signal in the short DRX cycle is duration_1, and the monitoring time window of the power saving signal in the long DRX cycle is duration_2. The values of the two time windows can be the same or different. The same situation is the same as Example 1. For different situations, for example, when the terminal is in a short DRX cycle, the power saving signal carries 2 short DRX cycles of power saving information; when the terminal is in a long DRX cycle, the power saving signal carries 1 long DRX cycle of power saving information, Then the base station can configure duration_1 to be greater than duration_2.

The base station can learn the DRX cycle of the terminal according to the DRX parameter configuration and the data arrival situation of the terminal, that is, the long DRX cycle or the short cycle, and according to the current DRX cycle of the terminal and the power saving signal search space configuration parameter, the first The subset indication information (parameter N) and the second subset indication information (parameter M) determine the monitoring opportunities of the power-saving signal (such as the monitoring start position of the power-saving signal and the duration of continuous monitoring of the power-saving signal), and the The signal monitoring opportunity sends a power-saving signal to indicate whether the terminal wakes up from the sleep state in the subsequent DRX cycle to monitor the PDCCH or continue to sleep.

For example: if the current terminal is in a short DRX cycle, that is, when the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the base station sends a power-saving signal every 2 listening cycles in the short DRX cycle that needs to be indicated, and the power-saving signal is located at At the position corresponding to the monitoring offset value offset of the first short DRX cycle, the monitoring of the power saving signal lasts for duration_1 time slots. If the current terminal enters the long DRX cycle, the base station sends a power-saving signal every 4 monitoring cycles of the long DRX that needs to be instructed. The power-saving signal is located at the position corresponding to the monitoring offset of the first long DRX cycle. The monitoring lasts duration_2 time slots. If the power-saving signal has an implicit indication function, that is, if the power-saving signal is not sent at the monitoring opportunity of the power-saving signal, it means that the terminal continues to sleep and does not enter the active state for DRX. At this time, the base station may not always be at the monitoring opportunity of the terminal. The terminal sends a power saving signal. If the power saving signal carries explicit indication information, the base station will send the power saving signal to the terminal at the time when the terminal is listening.

If the terminal receives the MAC CE carrying the DRX command, the DRX is turned on. At this time, the terminal enters the short DRX cycle, and starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). At this time, the terminal monitors the power-saving signal at the position corresponding to the listening offset value offset of the first short DRX cycle when receiving the MAC CE carrying the DRX command according to the monitoring parameters configured by the high-level signaling of the base station. The monitoring lasts duration_1 time slots.

In the short DRX cycle, the terminal only monitors the PDCCH during the activation period. Whenever the terminal receives a DCI with a new data indication, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal will use the short DRX cycle. During the short DRX cycle of the terminal, the terminal chooses to monitor the power saving signal every two monitoring cycles, and each monitoring opportunity is located at the monitoring offset of the first short DRX cycle At the position corresponding to the value offset, the monitoring of the power saving signal lasts for duration_1 time slots.

When the short DRX cycle timer (drx-ShortCycleTimer) times out or receives a MAC CE carrying a long DRX command sent by the base station, the terminal enters the long DRX cycle. When the terminal enters the long DRX cycle, the terminal monitors the power-saving signal every 4 monitoring cycles, and each monitoring opportunity is located at the position corresponding to the monitoring offset value of the long DRX cycle, and the power-saving signal monitoring lasts for duration_2 time slots.

During the long DRX activation period, when the terminal receives the DCI with the new data indication, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal is in a short DRX cycle. Then during the short DRX cycle of the terminal, the terminal monitors the power-saving signal every two monitoring cycles, and each monitoring opportunity is located at the position corresponding to the offset value of the first short DRX cycle, and the monitoring of the power-saving signal lasts for duration_1 hours Gap.

When the terminal is in the short DRX cycle and the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the terminal enters the long DRX cycle when it receives the MAC CE with the long DRX command sent by the base station. At this time, the terminal receives the power-saving signal at the position corresponding to the listening offset value offset of the first long DRX cycle after receiving the MAC CE. The power-saving signal monitoring lasts for duration_2 time slots, and then it will be performed every 4 listening cycles. Monitoring of power saving signals.

Example four

Example 4 is described by taking the short DRX cycle and the long DRX cycle respectively corresponding to a resource set (ie, search resource set) as an example.

In addition, the base station also configures the relevant parameters of the power-saving signal monitoring behavior for the terminal through high-level signaling: the monitoring duration related parameter N (N is an integer and N≥0) when the terminal is in a short DRX cycle, and the monitoring when the terminal is in a long DRX cycle The duration-related parameter M (M is an integer and M=K×m, m is an integer and m≥1, and K is a multiple of the long DRX cycle compared to the short DRX cycle). The meanings of M and N are: when the terminal is in a short DRX cycle, it monitors the power saving signal every N monitoring cycles, and when it is in a long DRX cycle, it monitors the power saving signal every M monitoring cycles. If the long DRX cycle is 4 times the short DRX cycle, this embodiment takes N=2 and M=4 as an example for description, that is, when the terminal is in the short DRX cycle, the power saving signal is monitored every 2 monitoring cycles, and the terminal When in a long DRX cycle, the power saving signal is monitored every 4 monitoring cycles, that is, every long DRX cycle is monitored once.

The base station can configure two control resource sets CORESET_1 and CORESET_2, corresponding to the resource sets where the power saving signal is located in the short DRX cycle and the long DRX cycle, respectively. In the short DRX cycle, the resource set corresponding to the power saving signal is CORESET_1, and in the long DRX cycle, the resource set corresponding to the power saving signal is CORESET_2. This collection of resources can be the same or different. The same situation is the same as Example 1. For different situations, for example, when the terminal is in a short DRX cycle, CORESET_1 occupies three symbols in the time domain; when the terminal is in a long DRX cycle, CORESET_1 occupies two symbols in the time domain.

For example: if the current terminal is in a short DRX cycle, that is, when the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the base station sends a power-saving signal every 2 listening cycles in the short DRX cycle that needs to be indicated, and the power-saving signal is located at At the position corresponding to the monitoring offset value offset of the first short DRX cycle, the resource set for monitoring the power saving signal is CORESET_1. If the current terminal enters the long DRX cycle, the base station sends a power-saving signal every 4 monitoring cycles of the long DRX that needs to be instructed. The power-saving signal is located at the position corresponding to the monitoring offset of the first long DRX cycle. The monitored resource collection is CORESET_2. If the power-saving signal has an implicit indication function, that is, if the power-saving signal is not sent at the monitoring opportunity of the power-saving signal, it means that the terminal continues to sleep and does not enter the active state for DRX. At this time, the base station may not always be at the monitoring opportunity of the terminal The terminal sends a power saving signal. If the power saving signal carries explicit indication information, the base station will send the power saving signal to the terminal at the time when the terminal is listening.

If the terminal receives the MAC CE carrying the DRX command, the DRX is turned on. At this time, the terminal enters the short DRX cycle, and starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). At this time, the terminal monitors the power-saving signal at the position corresponding to the listening offset value offset of the first short DRX cycle when receiving the MAC CE carrying the DRX command according to the monitoring parameters configured by the high-level signaling of the base station. The monitored resource collection is CORESET_1.

In the short DRX cycle, the terminal only monitors the PDCCH during the activation period. Whenever the terminal receives a DCI with a new data indication, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal will use the short DRX cycle. During the short DRX cycle of the terminal, the terminal chooses to monitor the power saving signal every two monitoring cycles, and each monitoring opportunity is located at the monitoring offset of the first short DRX cycle The location corresponding to the value offset, the resource set for monitoring the power-saving signal is CORESET_1.

When the short DRX cycle timer (drx-ShortCycleTimer) times out or receives a MAC CE carrying a long DRX command sent by the base station, the terminal enters the long DRX cycle. When the terminal enters the long DRX cycle, the terminal monitors the power saving signal every 4 monitoring cycles, and each monitoring opportunity is located at the position corresponding to the monitoring offset value offset of the long DRX cycle, and the monitored resource set is CORESET_2.

During the long DRX activation period, when the terminal receives the DCI with the new data indication, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal is in a short DRX cycle. Then during the short DRX cycle of the terminal, the terminal monitors the power-saving signal every two monitoring cycles, and each monitoring opportunity is located at the position corresponding to the monitoring offset value offset of the first short DRX cycle. The resource set for power-saving signal monitoring is CORESET_1.

When the terminal is in the short DRX cycle and the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the terminal enters the long DRX cycle when it receives the MAC CE with the long DRX command sent by the base station. At this time, the terminal will receive the power-saving signal at the position corresponding to the monitoring offset value offset of the first long DRX cycle after receiving the MAC CE. The resource set for power-saving signal monitoring is CORESET_2, and then it will be performed every 4 monitoring cycles. A monitoring of power saving signal.

Example 5

Example 5 is described by taking a short DRX cycle and a long DRX cycle corresponding to one monitoring pattern as an example.

In addition, the base station also configures the relevant parameters of the power-saving signal monitoring behavior for the terminal through high-level signaling: the monitoring duration related parameter N (N is an integer and N≥0) when the terminal is in short DRX, and the monitoring duration when the terminal is in long DRX is related Parameter M (M is an integer and M=K×m, m is an integer and m≥1, K is a multiple of the long DRX cycle compared to the short DRX cycle). The meanings of M and N are: when the terminal is in a short DRX cycle, it monitors the power saving signal every N monitoring cycles, and when it is in a long DRX cycle, it monitors the power saving signal every M monitoring cycles. If the long DRX cycle is 4 times the short DRX cycle, this embodiment takes N=2 and M=4 as an example for description, that is, when the terminal is in the short DRX cycle, the power saving signal is monitored every 2 monitoring cycles, and the terminal When in a long DRX cycle, the power saving signal is monitored every 4 monitoring cycles, that is, every long DRX cycle is monitored once.

The base station can configure two monitoring patterns, pattern_1 and pattern_2, which correspond to the monitoring patterns of the power saving signal in the short DRX cycle and the long DRX cycle, respectively. This collection of resources can be the same or different. The same situation is the same as Example 1. For different situations, for example, the monitoring pattern corresponding to the power saving signal in the short DRX cycle is pattern_1, which is the first symbol, and CORESET occupies three symbols. Then when the terminal is in the short DRX cycle, the power saving signal is in a time slot The symbol inside is {1, 2, 3}. The monitoring pattern of the power-saving signal in the long DRX cycle is pattern_2, which is the 4th symbol, and CORESET occupies three symbols. Then when the terminal is in the long DRX cycle, the symbol of the power-saving signal in a slot is {4, 5, 6 }.

For example: if the current terminal is in a short DRX cycle, that is, when the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the base station sends a power-saving signal every 2 listening cycles in the short DRX cycle that needs to be indicated, and the power-saving signal is located at At the position corresponding to the monitoring offset value offset of the first short DRX cycle, the monitoring pattern of the power saving signal in a time slot is pattern_1. If the current terminal enters the long DRX cycle, the base station sends a power-saving signal every 4 monitoring cycles of the long DRX that needs to be instructed. The power-saving signal is located at the position corresponding to the monitoring offset of the first long DRX cycle. The monitoring pattern in a time slot is pattern_2. If the power-saving signal has an implicit indication function, that is, if the power-saving signal is not sent at the monitoring opportunity of the power-saving signal, it means that the terminal continues to sleep and does not enter the active state for DRX. At this time, the base station may not always be at the monitoring opportunity of the terminal The terminal sends a power saving signal. If the power saving signal carries explicit indication information, the base station will send the power saving signal to the terminal at the time when the terminal is listening.

If the terminal receives the MAC CE carrying the DRX command, the DRX is turned on. At this time, the terminal enters the short DRX cycle, and starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). At this time, the terminal monitors the power-saving signal at the position corresponding to the listening offset value offset of the first short DRX cycle when receiving the MAC CE carrying the DRX command according to the monitoring parameters configured by the high-level signaling of the base station. The monitoring pattern in a time slot is pattern_1.

In the short DRX cycle, the terminal only monitors the PDCCH during the activation period. Whenever the terminal receives a DCI with a new data indication, it will start or restart the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the draft timer expires, the terminal will use a short DRX cycle. During the short DRX cycle of the terminal, the terminal chooses to monitor the power saving signal every two monitoring cycles, and each monitoring opportunity is located at the monitoring offset of the first short DRX cycle At the position corresponding to the value offset, the monitoring pattern of the power saving signal in a time slot is pattern_1.

If the short DRX cycle timer (drx-ShortCycleTimer) times out or receives a MAC CE carrying a long DRX command sent by the base station, the terminal enters the long DRX cycle. When the terminal enters the long DRX cycle, the terminal monitors the power saving signal every 4 listening cycles, and each listening opportunity is located at the position corresponding to the listening offset value offset of the long DRX cycle, and the listening pattern in a time slot is pattern_2.

If during the long DRX activation period, the terminal starts or restarts the DRX inactivity timer (drx-InactivityTimer) when it receives the DCI with the new data indication. When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal is in a short DRX cycle. Then, during the short DRX cycle of the terminal, the terminal monitors the power-saving signal every two monitoring cycles, and each monitoring opportunity is located at the position corresponding to the offset value offset of the first short DRX cycle, and the monitoring pattern in a time slot Is pattern_1.

When the terminal is in the short DRX cycle and the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the terminal enters the long DRX cycle when it receives the MAC CE with the long DRX command sent by the base station. At this time, the terminal will receive the power-saving signal at the position corresponding to the monitoring offset value of the first long DRX cycle after receiving the MAC CE. The monitoring pattern of the power-saving signal in a time slot is pattern_2, then every 4 Monitor the power saving signal once every monitoring cycle.

Example 6

Example 6 uses the combination of two optional parameter configurations, and describes the short DRX cycle and the long DRX cycle respectively corresponding to a listening opportunity offset value and a listening time window.

The base station can configure two offset values offset_1 and offset_2, corresponding to the short DRX cycle and the long DRX cycle, respectively. The two monitoring offset values can be the same or different. The same situation is the same as in Example 1. For different situations, for example, the offset value of the monitoring position of the power saving signal in the short DRX cycle is offset_1, and the monitoring position of the power saving signal in the long DRX cycle is determined according to the offset value offset_2. If the long DRX cycle requires a high delay in processing the power saving signal, offset_2 is greater than offset_1.

The base station can configure two monitoring time windows duration_1 and duration_2, which correspond to the number of time slots for continuously monitoring the power saving signal in the short DRX cycle and the long DRX cycle, respectively. The monitoring time window of the power saving signal in the short DRX cycle is duration_1, and the monitoring time window of the power saving signal in the long DRX cycle is duration_2. The values of the two time windows can be the same or different. The same situation is the same as Example 1. For different situations, for example, when the terminal is in a short DRX cycle, the power saving signal carries 2 short DRX cycles of power saving information; when the terminal is in a long DRX cycle, the power saving signal carries 1 long DRX cycle of power saving information, Then the base station can configure duration_1 to be greater than duration_2.

For example: if the current terminal is in a short DRX cycle, that is, when the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the base station sends a power-saving signal every 2 listening cycles in the short DRX cycle that needs to be indicated, and the power-saving signal is located at At the position corresponding to the monitoring offset value offset_1 of the first short DRX cycle, the power saving signal monitoring lasts for duration_1 time slots. If the current terminal enters the long DRX cycle, the base station sends a power-saving signal every 4 monitoring cycles of the long DRX that needs to be indicated. The power-saving signal is located at the position corresponding to the offset_2 of the first long DRX cycle. The monitoring lasts duration_2 time slots. If the power-saving signal has an implicit indication function, that is, if the power-saving signal is not sent at the monitoring opportunity of the power-saving signal, it means that the terminal continues to sleep and does not enter the active state for DRX. At this time, the base station may not always be at the monitoring opportunity of the terminal. The terminal sends a power saving signal. If the power saving signal carries explicit indication information, the base station will send the power saving signal to the terminal at the time when the terminal is listening.

If the terminal receives the MAC CE carrying the DRX command, the DRX is turned on. At this time, the terminal enters the short DRX cycle, and starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). At this time, the terminal monitors the power-saving signal at the position corresponding to the monitoring offset value offset_1 of the first short DRX cycle when receiving the MAC CE carrying the DRX command according to the monitoring parameters configured by the high-level signaling of the base station. The monitoring lasts duration_1 time slots.

In the short DRX cycle, the terminal only monitors the PDCCH during the activation period. Whenever the terminal receives a DCI with a new data indication, it will start or restart the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal will use the short DRX cycle. During the short DRX cycle of the terminal, the terminal chooses to monitor the power saving signal every two monitoring cycles, and each monitoring opportunity is located at the monitoring offset of the first short DRX cycle At the position corresponding to the value offset_1, the power-saving signal is monitored for duration_1 time slots.

When the short DRX cycle timer (drx-ShortCycleTimer) times out or receives a MAC CE carrying a long DRX command sent by the base station, the terminal enters the long DRX cycle. When the terminal enters the long DRX cycle, the terminal monitors the power-saving signal every 4 monitoring cycles, and each monitoring opportunity is located at the position corresponding to the monitoring offset value offset_2 of the long DRX cycle, and the power-saving signal monitoring lasts for duration_2 time slots.

During the long DRX activation period, when the terminal receives the DCI with the new data indication, it starts or restarts the DRX inactivity timer (drx-InactivityTimer). When the timer expires, the terminal enters a dormant period, that is, an inactive state, and at the same time the terminal starts or restarts the short DRX cycle timer (drx-ShortCycleTimer). Before the timer expires, the terminal is in a short DRX cycle. Then during the short DRX cycle of the terminal, the terminal monitors the power-saving signal every two monitoring cycles, and each monitoring opportunity is located at the position corresponding to the offset_1 of the first short DRX cycle, and the monitoring of the power-saving signal lasts for duration_1 hours Gap.

When the terminal is in the short DRX cycle and the short DRX cycle timer (drx-ShortCycleTimer) does not expire, the terminal enters the long DRX cycle when it receives the MAC CE with the long DRX command sent by the base station. At this time, the terminal will receive the power-saving signal at the position corresponding to the offset_2 of the monitoring offset value of the first long DRX cycle after receiving the MAC CE. The monitoring of the power-saving signal lasts for duration_2 time slots, and then every 4 subsequent monitoring cycles. A monitoring of power saving signal.

Example Seven

Example 7 is described by taking the short DRX cycle and the long DRX cycle respectively corresponding to the offset values of two listening opportunities.

The base station uses high-level signaling to configure the parameters of the search space for the terminal to send the power saving signal. Taking the power saving signal based on the PDCCH as an example, the format of the parameter configuration is similar to the parameter configuration of the conventional PDCCH search space. Among them, the monitoring period is The value is the period length of the short DRX cycle or the period length of the common divisor of the long DRX cycle.

In addition, the base station also configures the relevant parameters of the power-saving signal monitoring behavior for the terminal through high-level signaling. The parameters may include: if the monitoring period is configured as a short DRX cycle, the terminal is in the short DRX cycle and the monitoring duration related parameters N (N is Integer and N≥0), the monitoring duration related parameter M when the terminal is in the long DRX cycle (M is an integer and M=K×m, m is an integer and m≥1, K is the long DRX cycle compared to the short DRX cycle multiple). The meanings of M and N are: when the terminal is in a short DRX cycle, it monitors the power saving signal every N monitoring cycles, and when it is in a long DRX cycle, it monitors the power saving signal every M monitoring cycles. If the long DRX cycle is 4 times the short DRX cycle, take N=2, M=4 as an example, that is, when the terminal is in the short DRX cycle, the power-saving signal is monitored every 2 monitoring cycles, and when the terminal is in the long DRX cycle , Monitor the power-saving signal every 4 monitor cycles, that is, monitor once every long DRX cycle.

If the monitoring period in the search space of the power saving signal is configured to be an integer multiple of the short DRX cycle, the basic monitoring process is the same as the case where the short DRX cycle is configured as described above.

If the monitoring period is configured to be less than the period length N1 of the long DRX period, and the value is not an integer multiple of the short DRX period, or the monitoring period of the common divisor of the long DRX period. In addition, the terminal can also be configured with monitoring duration related parameters K1 and K2, (K1 and K2 are integers, K1≥0, K2≥0), which correspond to the short DRX cycle and the long DRX cycle, respectively. When the terminal is in a short DRX cycle, the monitoring duration is K1×N1, and when the terminal is in a long DRX cycle, the monitoring duration is K2×N1. It is worth noting that, here, the monitoring duration related parameters include monitoring the power-saving signal only for a DRX of a short DRX cycle or a long DRX cycle.

The base station can configure two listening opportunity offset values offset_1 and offset_2, which correspond to a short DRX cycle and a long DRX cycle, respectively. The two monitoring offset values can be the same or different. The same situation is the same as in Example 1.

The listening opportunity offset value can be in the following situations:

(1) The indication offset is displayed in the search space configuration;

(2) Calculate the interval value offset_gap from the start point of the DRX activation period configured by higher layer signaling, that is, the listening offset value offset is:

offset=offset_DRX–offset_gap

Among them, offset_DRX is the offset value of the start position of the DRX activation period. The formula here mainly represents the positional relationship between the power-saving signal and the start position of the DRX activation period. In addition, it can be considered according to the specific value whether the monitoring position of the power-saving signal is within the current DRX cycle, that is, due to the interval value from the start point of the DRX activation period offset_gap is greater than the offset value of the start position of the DRX active period and is located in the previous DRX cycle.

(3) The interval range offset_range from the start point of the DRX activation period configured through the search space set or high-level signaling. The user only needs to continuously monitor the power-saving signal within the offset_range from the start point of the DRX activation period. If the configured value of the monitoring period of the power saving signal is less than the DRX cycle, there may be multiple power saving signals in one DRX cycle, and the user only needs to continuously monitor the power saving signal within the interval offset_range from the starting point of the DRX activation period.

(4) A certain monitoring offset value offset or an offset interval offset_gap from the start point of the DRX activation period configured through a search space configured in the search space set or the interval range offset_range from the start point of the DRX activation period configured in the search space set or high-level signaling. That is, in addition to the monitoring offset value offset configured by the base station in the search space, the interval range offset_range from the start point of the DRX activation period configured through the search space set or high-level signaling. If the configured value of the monitoring period of the power saving signal is less than the DRX cycle, there may be multiple power saving signals in a DRX cycle. The user only needs to be within the interval offset_range from the start point of the DRX activation period based on the monitoring offset value offset or offset_gap from the start point of the DRX activation period to monitor the power saving signal. Here, monitoring situations 1) and 2) of the power saving signal are performed based on the monitoring offset value offset or the offset interval offset_gap from the start point of the DRX activation period.

It should be noted that the above several situations of the offset value of the listening opportunity are applicable to both the short DRX and the long DRX, and therefore, there is no difference.

For different situations, the start position of the monitoring opportunity in the short DRX cycle is determined according to the offset value offset_1, and the start position of the monitoring activation in the long DRX cycle is determined according to the offset value offset_2. If the long DRX cycle requires a high delay in processing the power saving signal, offset_2 is greater than offset_1. Other parameters are similar to the parameter configuration of the conventional PDCCH search space set, and will not be repeated here.

Subsequent users monitor the corresponding power-saving signal in the corresponding DRX cycle according to the power-saving signal configured by the base station. The process is the same as that in the second embodiment, and will not be repeated.
