Description

Power-saving signal configuration and transmission method and device
The present application claims priority of chinese patent application entitled "power saving signal configuration and transmission method and apparatus" filed by chinese patent office on 1/8/2019 under application number 201910709030.2, the entire contents of which are incorporated herein by reference.
Technical Field
The present application relates to the field of wireless communication technologies, and in particular, to a power saving signal configuration and transmission method and apparatus.
Background
In the 5G NR system, in order to obtain downlink scheduling information, a terminal needs to monitor a Physical Downlink Control Channel (PDCCH) at each PDCCH monitoring opportunity (PDCCH monitoring occasion) to determine whether user scheduling information is transmitted. Wherein, one PDCCH monitoring opportunity corresponds to a time length, for example, the time length may be several symbols. A process of performing PDCCH monitoring at one PDCCH monitoring opportunity is a primary PDCCH decoding process, and whether the PDCCH transmits Downlink Control Information (DCI) carrying user scheduling information is determined according to a Cyclic Redundancy Check (CRC) check result. If the PDCCH transmits the 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 configures Discontinuous Reception (DRX), the terminal will not continuously monitor the PDCCH. The terminal monitors the PDCCH only when a DRX activation period (DRX on-duration) or an inactivity timer (inactivity timer) is not timed out, so as to reduce the power consumption of the terminal. The terminal can configure a long DRX period or a short DRX period, and can also configure the long DRX period and the short DRX period at the same time. Wherein the long DRX cycle may be an integer multiple of the short DRX cycle.
Before the active period (on-duration) of the DRX cycle, the base station may send a power-saving signal to the terminal for dynamically indicating whether the terminal performs PDCCH monitoring during the next active period(s) of the DRX cycle. The power saving signal is a physical layer signal of a PDCCH type, and the monitoring process of the power saving signal is consistent with the monitoring behavior of a PDCCH scheduled by a user.
How to match the monitoring opportunity of the power saving signal with the activation period of the DRX is a problem to be solved at present under the condition that the terminal configures a long DRX cycle and a short DRX cycle at the same time.

Detailed Description
The embodiment of the application provides a physical layer transmission design scheme of a power-saving signal based on a PDCCH (physical Downlink control channel), which can be suitable for monitoring the power-saving signal under the condition that a terminal is configured with a long DRX period and a short DRX period at the same time.
First, a brief description will be given of a DRX mechanism and a configuration of a PDCCH monitoring opportunity.
Fig. 1 illustrates a DRX cycle. One DRX cycle includes a DRX active period (on-duration) and a DRX inactive period (DRX off, also called openness for DRX). During one DRX cycle, the terminal monitors the PDCCH only during a DRX active period (on-duration) period, and during a DRX inactive period (opportunity for DRX), the terminal enters a sleep mode in which the PDCCH is not received to reduce power consumption.
The DRX information (DRX-Info, i.e., DRX parameter) specifically includes the following items:
-DRX activation timer (DRX-on-duration timer): the duration of continuously monitoring the PDCCH from the beginning of the DRX period;
-DRX slot offset (DRX-SlotOffset): a time interval from the beginning of a DRX activation timer (DRX-on-duration timer);
-DRX inactivity timer (DRX-inactivity timer): when the PDCCH indicates that new Uplink (UL) or Downlink (DL) data is transmitted, the PDCCH is started after receiving the data, and when the timer is overtime, the terminal enters an inactive state;
DRX downlink retransmission timer (DRX-retransmission timerdl): for each downlink Hybrid Automatic Repeat reQuest (HARQ) process, the maximum duration before the downlink retransmission data arrives;
DRX uplink retransmission timer (DRX-retransmission timer ul): for each uplink HARQ process, the maximum duration before the uplink retransmission data arrives;
long DRX cycle start offset (DRX-LongCycleStartOffset): the location where the long DRX cycle starts;
-long DRX cycle (DRX-LongCycle): the cycle length of the long DRX is integral multiple of the short DRX;
short DRX cycle (DRX-ShortCycle): the cycle length of the short DRX, which is an optional parameter;
short DRX cycle timer (DRX-ShortCycleTimer): during the running period of the timer, the terminal adopts a short DRX period, the value of the short DRX period is integral multiple of the short DRX period, and the parameter is an optional parameter;
DRX downlink HARQ RTT timer (DRX-HARQ-RTT-TimerDL): for each downlink HARQ process, a Media Access Control (MAC) entity needs to perform a minimum duration before a downlink HARQ retransmission;
DRX uplink HARQ RTT timer (DRX-HARQ-RTT-timerll): for each uplink HARQ process, the MAC entity needs to perform a minimum duration before uplink HARQ retransmission.
The terminal is in an active state during any one of a DRX activation timer (DRX-on-duration timer), a DRX inactivity timer (DRX-inactivity timer), a DRX downlink retransmission timer (DRX-retransmission timer dl), and a DRX uplink retransmission timer (DRX-retransmission timer ul).
Under the condition that the terminal configures a short DRX cycle and a long DRX cycle at the same time, if the terminal receives a MAC CE (i.e., a DRX Command MAC CE, where CE is an acronym of control element and denotes a control unit) carrying a DRX Command or a DRX inactivity timer (DRX-inactivity timer) expires, the terminal enters the short DRX cycle and starts or restarts the short DRX cycle timer (DRX-short cycletimer). When a short DRX cycle timer (DRX-ShortCycleTimer) times out, the terminal enters a long DRX cycle. If new data arrives in the active period of the DRX, the terminal starts or restarts a DRX inactivity timer (DRX-inactivity timer).
The monitoring opportunity of the PDCCH is configured in a mode of searching a space set. One search space set consists of a set of candidate PDCCHs, and the terminal needs to blind-detect the PDCCHs in a desired DCI format (DCI format) within the search space set.
The configuration parameters of the search space set of the PDCCH may include:
-an index of the search space set, search space ID;
-a control resource set number, i.e. a CORESET ID, for establishing a connection between the search space set s and the control resource set p;
PDCCH listening period kp,sAnd offset value op,sThe units are slots (slots), and the terminal determines the slots for monitoring the downlink control channel according to the configuration parameters;
-a monitoring pattern of PDCCH within a time slot;
-the number of PDCCH candidates (PDCCH candidates) included in each aggregation level in the search space set
Figure BDA0002206146160000111
The supported aggregation level comprises { 124816 } and is configured through independent parameters;
-a flag searchspactetype for distinguishing whether the current search space set is a common search space set or a terminal-specific search space set;
PDCCH listening time window, i.e. the number of consecutive time slots in which the search space set exists.
Introducing a power-saving signal before the activation period (on-duration) of the DRX can dynamically instruct the terminal whether to perform PDCCH monitoring during the activation period of the next DRX cycle or cycles. Power saving signal a PDCCH type physical layer signal whose monitoring process is consistent with the PDCCH monitoring behavior scheduled by the user.
According to the above description, the monitoring opportunities of PDCCH are periodic and have fixed values, and it is possible to receive PDCCH at each PDCCH monitoring opportunity. If the terminal configures a long DRX cycle and a short DRX cycle at the same time, the monitoring period for the PDCCH-based power saving signal may be affected by the DRX cycle, and the effect includes:
(1) If the monitoring period of the power saving signal based on the PDCCH is configured according to the short DRX period, the long DRX period comprises a plurality of PDCCH monitoring opportunities, namely, the monitoring of the power saving signal is carried out for a plurality of times in one long DRX period, and the condition causes unnecessary power consumption of the terminal.
(2) If the monitoring period of the PDCCH-based power saving signal is configured according to the long DRX cycle, the time when the timer DRX-ShortCycleTimer is started or restarted is different due to the burstiness of data arrival, which may cause the time when the terminal monitors the long DRX cycle to be unfixed. The terminal monitors the power saving signal according to the long DRX period, which results in that no monitoring opportunity of the power saving signal exists before the active period (on-duration) of the long DRX period, or the monitoring opportunity of the power saving signal has a longer time interval from the active period (on-duration) of the long DRX period.
In order to solve the above problem, embodiments of the present application provide a physical layer transmission design scheme for a power saving signal based on a PDCCH, which can be applied to perform a monitoring action of the power saving signal when a terminal configures a long DRX cycle and a short DRX cycle at the same time.
In the embodiment of the present application, for a situation that a terminal configures two DRX cycles, that is, a long DRX cycle and a short DRX cycle, the following schemes are provided:
The first scheme is as follows: configuring search space set configuration information of a power saving signal used when the terminal is in a short DRX period, monitoring the power saving signal by using the configuration information when the terminal is in the short DRX period, and not monitoring the power saving signal when the terminal is in a long DRX period;
scheme II: configuring search space set configuration information of a power saving signal used when the terminal is in a long DRX period, monitoring the power saving signal by using the configuration information when the terminal is in the long DRX period, and not monitoring the power saving signal when the terminal is in a short DRX period;
and a third scheme is as follows: and configuring the search space set configuration information of the power saving signal used in the short DRX period and the search space set configuration information of the power saving signal used in the long DRX period for the terminal, so that the terminal monitors the power saving signal by using different configuration information when in the short DRX period and the long DRX period.
For example, two listening periods, i.e., a first listening period T1 and a second listening period T2, may be configured for the terminal, where the first listening period T1 is an integer multiple of the short DRX period, i.e., T1 is N × short DRX period length, N is an integer and N ≧ 0, and the second listening period T2 is an integer multiple of the long DRX period, i.e., T2 is M × long DRX period length, M is an integer and M ≧ 1. When the terminal is in different DRX periods, different monitoring periods can be adopted for monitoring the power-saving signal. That is, when the terminal is in the short DRX cycle, the power saving signal is monitored using the first monitoring period T1; when the terminal is in the long DRX cycle, the second listening period T2 is used for listening for the power saving signal. By adopting the embodiment of the application, the monitoring opportunity of the power saving signal can be matched with the activation period of the DRX under the condition that the terminal is simultaneously configured with the long DRX period and the short DRX period.

It is to be understood that the terms "first," "second," and the like in the embodiments of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used are interchangeable under appropriate circumstances and can be implemented in sequences other than those illustrated or otherwise described herein with respect to the embodiments of the application, for example.
Referring to fig. 2, a schematic configuration flow diagram of a power saving signal according to an embodiment of the present application is shown. As shown, the process may include:
s201: the base station configures search space set configuration information of the power saving signal.
Wherein the search space set configuration information of the power saving signal includes at least one of first configuration information and second configuration information. The first configuration information is search space set configuration information of a power saving signal used when the terminal is in a short Discontinuous Reception (DRX) cycle, and the second configuration information is search space set configuration information of the power saving signal used when the terminal is in a long DRX cycle.
S202: and the base station sends the search space set configuration information of the power saving signal to the terminal.
The process shown in fig. 2 may further include the following steps:
the base station determines the DRX period of the terminal (i.e. whether the DRX period of the terminal is a short DRX period or a long DRX period) according to the DRX configuration information and the data transmission condition of the terminal, determines the monitoring opportunity of the power saving signal (such as the monitoring starting position of the power saving signal and the time slot length of the continuous monitoring power saving signal) according to the DRX period of the terminal and the power saving signal searching space set configuration information, and sends the power saving signal according to the monitoring opportunity of the power saving signal.
According to the above-described procedure shown in fig. 2, the base station may configure corresponding power saving signal search space set configuration information for at least one of the short DRX cycle and the long DRX cycle. The method specifically comprises the following conditions:
case 1: the first configuration information is configured for only the short DRX cycle. And when the terminal is in the short DRX period, monitoring the power saving signal by using the first configuration information, and when the terminal is in the long DRX period, not monitoring the power saving signal.
Case 2: the second configuration information is configured only for the long DRX cycle. And when the terminal is in the long DRX period, monitoring the power saving signal by using the second configuration information, and when the terminal is in the short DRX period, not monitoring the power saving signal.
Case 3: the first configuration information is configured for both the short DRX cycle and the long DRX cycle. Monitoring the power saving signal by using first configuration information when the terminal is in a short DRX period; and when the terminal is in the long DRX period, monitoring the power saving signal by using the second configuration information.
As can be seen from the above description, in the embodiments of the present application, the configuration of the power saving signal search space set configuration parameters is performed for the short DRX cycle and the long DRX cycle, so that the terminal can flexibly monitor the power saving signal when the short DRX cycle and the long DRX cycle are configured at the same time, and the problem that the time when the power saving signal monitoring opportunity occurs is not matched with the starting point of the active period (on-duration) of the DRX cycle due to the dynamic changes of the short DRX cycle and the long DRX cycle is solved.
Optionally, in the search space set configuration information of the power saving signal, the first configuration information may include a first listening period T1, and the second configuration information may include a second listening period T2. The first listening period T1 is a listening period of a power saving signal used when the terminal is in the short DRX cycle, and the second listening period T2 is a listening period of a power saving signal used when the terminal is in the long DRX cycle.
The first monitoring period T1 is N times the short DRX cycle (N is an integer greater than or equal to zero), that is, the value T1 of the first monitoring period is N × the length of the short DRX cycle, N is an integer, and N is greater than or equal to 0; the second monitoring period T2 is M times the long DRX cycle (M is an integer greater than or equal to 1), that is, the value T2 of the second monitoring period is M × the length of the long DRX cycle, M is an integer, and M is greater than or equal to 1.
When N is 0, it indicates that the terminal does not monitor the power saving signal when in the short DRX cycle.
Alternatively, at least one of the first listening period T1 and the second listening period T2 may not be included in the search space set configuration information of the power saving signal, but may be implicitly indicated to the terminal by the base station. Specifically, the short DRX cycle configured by the base station for the terminal may be associated with the first listening period T1, and the long DRX cycle configured by the base station for the terminal may be associated with the second listening period T2. That is, the terminal may obtain the length of the first listening period T1 associated therewith according to the length of the short DRX cycle configured thereto by the base station (T1 ═ N × short DRX cycle length), and the terminal may obtain the length of the second listening period T2 associated therewith according to the length of the long DRX cycle configured thereto by the base station (T2 ═ M × long DRX cycle length).
Under the condition that two different power saving signal monitoring periods (a first monitoring period T1 and a second monitoring period T2) are respectively configured for the short DRX period and the long DRX period, the terminal can monitor the power saving signal according to the monitoring opportunity corresponding to the first monitoring period T1 when in the short DRX period and monitor the power saving signal according to the monitoring opportunity corresponding to the second monitoring period T2 when in the long DRX period, and further the terminal can flexibly monitor the power saving signal under the condition that the short DRX period and the long DRX period are simultaneously configured, and the problem that the time when the power saving signal monitoring opportunity appears is not matched with the starting point of the activation period (on-duration) of the DRX period due to the dynamic change of the short DRX period and the long DRX period is solved. The method can be embodied in the following two aspects:
in the first aspect, in the conventional scheme, if the monitoring period of the PDCCH-based power saving signal is configured according to the short DRX cycle, the long DRX cycle includes multiple PDCCH monitoring opportunities, that is, multiple times of monitoring of the power saving signal will be performed in one long DRX cycle, which causes unnecessary power consumption of the terminal. By adopting the above embodiment of the present application, the monitoring opportunity corresponding to the second monitoring period T2 is used to monitor the power saving signal in the long DRX cycle, and the second monitoring period T2 is a multiple of the short DRX monitoring period T1, for example, the monitoring of the power saving signal is performed every multiple short DRX cycles, where the multiple short DRX cycles have a length equal to one long DRX cycle, so that the monitoring opportunity of the power saving signal included in the long DRX cycle is less than the PDCCH monitoring opportunity, and thus compared with the above conventional scheme, unnecessary power consumption generated by the terminal can be reduced.
In a second aspect, in a conventional scheme, if a monitoring period of a power saving signal based on a PDCCH is configured according to a long DRX cycle, since data arrival is bursty, a DRX inactivity timer (DRX-inactivity timer) is started after the data arrival, and the DRX inactivity timer (DRX-short DRX timer) is started or restarted after the timer expires, a time at which the DRX-short DRX timer is started or restarted is not fixed, and when the DRX-short DRX cycle timer (DRX-short DRX timer) expires, a terminal enters the long DRX cycle, which further causes a starting point of a period when the terminal monitors the power saving signal to be mismatched with a starting point of an active period of the long DRX cycle. In this way, the terminal monitors the power saving signal according to the long DRX cycle, which may result in that there may be no monitoring opportunity of the power saving signal before the active period (on-duration) of the long DRX cycle, or the monitoring opportunity of the power saving signal is spaced apart from the active period (on-duration) of the long DRX cycle by a longer time interval. By adopting the above embodiment 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 monitoring opportunity corresponding to the first monitoring cycle T1 in the short DRX cycle, and monitors the power saving signal according to the monitoring opportunity corresponding to the second monitoring cycle T2 in the long DRX cycle. Compared with the conventional scheme, 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, so that the power saving signal can be received before the activation period of each long DRX cycle, and the time interval between the monitoring opportunity of the power saving signal and the activation period (on-duration) of the long DRX cycle can be avoided to be longer, thereby improving the possibility of receiving the power saving signal and reducing unnecessary power consumption generated by the terminal.
Alternatively, in some embodiments, in the search space set configuration information of the power saving signal, the first configuration information may include a first listening opportunity offset _1, and the second configuration information may include a second listening opportunity offset _ 2. The first and second listening opportunity offsets offset _1 and offset _2 correspond to a short DRX cycle and a long DRX cycle, respectively. The first listener offset _1 is a listener offset of a power saving signal used when the terminal is in a short DRX cycle, and the second listener offset _2 is a listener offset of a power saving signal used when the terminal is in a long DRX cycle, that is, when the terminal is in a short DRX cycle, the offset of the listener power saving signal is the first listener offset _1, and when the terminal is in a long DRX cycle, the offset of the listener power saving signal is the second listener offset _ 2. Different monitoring opportunity offsets are configured aiming at the short DRX period and the long DRX period, and the monitoring opportunity of the power saving signal can be more flexibly configured aiming at the monitoring complexity and the reliability of the power saving signal required by different DRX periods.
Alternatively, the units of the first and second listening opportunity offsets offset _1 and offset _2 may be slots, and the starting position of the listening opportunity of the power-saving signal in the short DRX cycle may be determined according to the first listening opportunity offset _1, and the starting position of the listening opportunity of the power-saving signal in the long DRX cycle may be determined according to the second listening opportunity offset _2, by way of example, in units of slots.
Alternatively, the unit of the first and second snoop opportunity offsets offset _1 and offset _2 may be a slot.
For example, the first monitoring opportunity offset needs to satisfy the following relationship in units of time slots, that is, a certain time interval (which may also be referred to as a time interval of the monitoring opportunity of the power saving signal from the short DRX cycle, that is, a time interval of the monitoring opportunity of the power saving signal from the active period of the short DRX cycle) is satisfied between the power saving signal and the start time of the first short DRX cycle in the monitoring cycle:
Figure BDA0002206146160000181
the above formula expresses:
if offset _ short is less than or equal to os-DRXmod(ks-shortDRX) Then the first listening opportunity offset satisfies the following relationship:
os-DRXmod(ks-shortDRX)-offset_1mod(ks-shortDRX)＝offset_short
in other cases, the first listening opportunity offset satisfies the following relationship:
ks-shortDRX+offset_1mod(ks-shortDRX)-offset_1mod(ks-shortDRX)＝offset_short
wherein, Os-DRXFor long DRX cycle start offset, ks-shortDRXFor the short DRX cycle, amod (B) represents performing modulo-B mode operation on the a value, offset _1 is the first listening opportunity offset, and offset _ short is the time interval of the power saving signal from the short DRX cycle (hereinafter referred to as the first time interval).
The second listening opportunity offset needs to satisfy the following relationship, that is, a certain time interval (which may also be referred to as a time interval of the listening opportunity of the power saving signal from the long DRX cycle, that is, a time interval of the listening opportunity of the power saving signal from the active period of the long DRX cycle) is satisfied between the power saving signal and the start time of the first long DRX cycle within the listening cycle:
Figure BDA0002206146160000182
The above formula expresses:
if offset _ long is less than or equal to os-DRXThen the second listening opportunity offset satisfies the following relationship:
os-DRX-offset_2mod(ks-longDRX)＝offset_long
in other cases, the second listening opportunity offset satisfies the following relationship:
ks-longDRX+os-DRX-offset_2mod(ks-longDRX)＝offset_long
wherein, Os-DRXFor the long DRX cycle start offset, offset _2 is the second listening opportunity offset, and offset _ long is the time interval of the power saving signal from the long DRX cycle (hereinafter referred to as the second time interval).
Alternatively, the values of the first and second listening opportunity offsets offset _1 and offset _2 may be the same or different.
Alternatively, the first time interval offset _ short (i.e. the time interval between the power saving signal and the short DRX cycle) may be configured by the high layer signaling alone, or may be implicitly indicated by the first monitoring opportunity offset configured in the search space set configuration information of the power saving signal, that is, according to the relationship defined above between the two, the first time interval offset _ short may be determined and obtained by the first monitoring opportunity offset, without additionally configuring the first time interval offset _ short, only by agreeing or configuring a relationship that needs to be satisfied between the first monitoring opportunity offset and the first time interval offset _ short. The first time interval offset _ short may also be configured simultaneously with the first listening opportunity offset of the power saving signal.
Alternatively, the second time interval offset _ long (i.e. the time interval between the power saving signal and the long DRX cycle) may be configured by a higher layer signaling alone, or may be implicitly indicated by the second monitoring opportunity offset configured in the search space set configuration information of the power saving signal, that is, according to the relationship defined above, the second time interval offset _ long may be determined and obtained by the second monitoring opportunity offset, without additionally configuring the second time interval offset _ long, and only the relationship that needs to be satisfied between the second monitoring opportunity offset and the second time interval offset _ long needs to be agreed or configured. The second time interval offset _ long may also be configured simultaneously with the second listening opportunity offset of the power saving signal.
Optionally, in some embodiments, in the power saving signal search space set configuration information, the first configuration information may include a first listening time window duration _1, and the second configuration information may include a second listening time window duration _ 2. The first and second listening time windows duration _1 and _2 correspond to a short DRX cycle and a long DRX cycle, respectively, and indicate a time length for continuously listening to the power-saving signal. Different monitoring time windows are configured aiming at the short DRX period and the long DRX period, so that the monitoring opportunity of the power-saving signal can be configured more flexibly, and the time windows can be configured according to requirements during specific implementation, thereby taking the reliability of power-saving signal transmission and the effective utilization of system resources into consideration.
Specifically, the first duration _1 is a slot length of continuously monitoring the power-saving signal before the DRX active period when the terminal is in the short DRX cycle, and the second duration _2 is a slot length of continuously monitoring the power-saving signal before the DRX active period when the terminal is in the long DRX cycle. That is, the continuous duration for monitoring the power-saving signal before the active period (on-duration) of the short DRX cycle is duration _1 when the terminal is in the short DRX cycle, and the continuous duration for monitoring the power-saving signal before the active period (on-duration) of the long DRX cycle is duration _2 when the terminal is in the long DRX cycle. The values of duration _1 and duration _2 may be the number of slots.
Optionally, the values of the first listening time window duration _1 and the second listening time window duration _2 may be the same or different.
Optionally, in some embodiments of the present application, in the power saving signal search space set configuration information, the first configuration information may include a first control resource set CORESET _1 associated with the search space set, and the second configuration information may include a second control resource set CORESET _ 2. The first control resource set CORESET _1 and the second control resource set CORESET _2 correspond to a short DRX cycle and a long DRX cycle, respectively. Different control resource sets are configured aiming at the short DRX period and the long DRX period, so that time-frequency resources used by the power-saving signal can be more flexibly configured, and the control resource sets can be configured according to requirements during specific implementation, thereby taking the reliability of power-saving signal transmission and the effective utilization of system resources into consideration.
The first control resource set CORESET _1 is a resource occupied by the power saving signal in the short DRX cycle, and may include a time domain resource, a frequency domain resource, a beam, and the like, or may include both the frequency domain resource and the time domain resource and the beam; the second control resource set CORESET _2 is a resource occupied by the power saving signal in the long DRX cycle, and may include a time domain resource, a frequency domain resource, or a beam, or may include both a frequency domain resource and a time domain resource and a beam.
Optionally, the first control resource set CORESET _1 and the second control resource set CORESET _2 may be the same resource set or different resource sets.
Optionally, in some embodiments, in the power saving signal search space set configuration information, the first configuration information includes a first power saving signal listening pattern _1, and the second configuration information includes a second power saving signal listening pattern _ 2. The first power saving signal monitor pattern _1 and the second power saving signal monitor pattern _2 correspond to a short DRX cycle and a long DRX cycle, respectively. That is, the first power saving signal monitor pattern _1 is a power saving signal monitor pattern used when the terminal is in the short DRX cycle, and the second power saving signal monitor pattern _2 is a power saving signal monitor pattern used when the terminal is in the long DRX cycle. Different power-saving signal monitoring patterns are configured aiming at the short DRX period and the long DRX period, so that time domain resources used by the power-saving signals can be more flexibly configured, and the power-saving signal monitoring patterns can be configured according to requirements during specific implementation, thereby taking the reliability of power-saving signal transmission and the effective utilization of system resources into consideration.
The power saving signal listening pattern may be used to indicate a time domain resource occupied by the power saving signal, such as a starting symbol of the power saving signal in one slot and a number of symbols of a continuous transmission from the starting symbol.
Alternatively, the first power saving signal listening pattern _1 and the second power saving signal listening pattern _2 may be the same or different.
Optionally, in some embodiments of the present application, the base station may combine the power saving signal search space set configuration information described in one or more embodiments to configure one search space set, or may configure two search space sets.
Optionally, if the search space set is configured in a search space set, the search space set configuration information of the search space set includes the first configuration information, or includes the second configuration information, or includes the first configuration information and the second configuration information.
Optionally, if the configuration is configured in two search space sets (a first search space set and a second search space set), the first search space set corresponds to the short DRX cycle, and the search space set configuration information corresponding to the first search space set includes first configuration information, such as the first listening period T1, and may further include one or more of the first listening opportunity offset _1, the first listening time window duration _1, the first control resource set CORESET _1, and the first power saving signal listening pattern _ 1; the second search space set corresponds to the long DRX cycle, and the search space set configuration information corresponding to the second search space set includes second configuration information, for example, includes the second listening period T2, and may further include one or more of the second listening opportunity offset _2, the second listening time window duration _2, the second control resource set CORESET _2, and the second power saving signal listening pattern _ 2.
Optionally, in some embodiments, in the case of transmitting the power saving signal using a plurality of beams (the plurality refers to at least two, and the plurality of beams may be a plurality of beams in the same direction, or a plurality of beams in different directions), the base station may configure the power saving signal search space set configuration information in one of the following two manners, specifically:
mode 1: the base station configures a search space set corresponding to each beam of the plurality of beams, and the search space set configuration information corresponding to each search space set includes at least one of first configuration information and second configuration information.
For example, the base station configures a search space set 1, a search space set 2, and a search space set 3 for the power saving signal to transmit the power saving signal using 3 beams. The search space set configuration information corresponding to the search space set 1 includes first configuration information (i.e., search space set configuration information of a power saving signal used when the terminal is in a short DRX cycle) and second configuration information (i.e., search space set configuration information of a power saving signal used when the terminal is in a long DRX cycle). The search space set configuration information corresponding to the search space set 2 and the search space set 3 also includes first configuration information and second configuration information, respectively. For a detailed description of the first configuration information and the second configuration information, reference may be made to the foregoing embodiments.
Mode 2: the base station respectively configures a first search space set and a second search space set corresponding to each beam of the plurality of beams, the search space set configuration information corresponding to the first search space set includes first configuration information, and the search space set configuration information corresponding to the second search space set includes second configuration information.
For example, the base station configures 6 search space sets (search space sets 1-6) for the power saving signal, where the search space set 1 and the search space set 2 correspond to the same beam (i.e., a control resource set associated with the search space set 1 and a control resource set associated with the search space set 2 correspond to the same beam), the search space set 3 and the search space set 4 correspond to the same beam, and the search space set 5 and the search space set 6 correspond to the same beam. The search space set configuration information corresponding to the search space set 1, the search space set 3, and the search space set 5 includes first configuration information (i.e., the search space set configuration information of the power saving signal used when the terminal is in the short DRX cycle), and the search space set configuration information corresponding to the search space set 2, the search space set 4, and the search space set 6 includes second configuration information (i.e., the search space set configuration information of the power saving signal used when the terminal is in the long DRX cycle). For a detailed description of the first configuration information and the second configuration information, reference may be made to the foregoing embodiments.
Further, the base station may also send a higher layer signaling to the terminal, where the higher layer signaling is used to notify one or two time intervals respectively associated with the plurality of search space sets. If the search space set is associated with a time interval, the time interval is the time interval from the monitoring opportunity of the power saving signal shared by the terminal in the short DRX period or the long DRX period to the short DRX period; if the search space set is associated with two time intervals, a first time interval of the two time intervals is a time interval from a monitoring opportunity of the power saving signal used when the terminal is in the short DRX period to the short DRX period, and a second time interval of the two time intervals is a time interval from the monitoring opportunity of the power saving signal used when the terminal is in the long DRX period to the short DRX period.
It should be noted that the embodiments on the base station side may be used independently, or may be combined arbitrarily, and the present application is not limited to this.
For example, the power saving signal search space set configuration information configured by the base station includes two monitoring periods, and may further include one or more of the following information (parameters):
the number of the monitoring opportunity offset parameters may be one or two (see the foregoing embodiment for the case of two), and if the number of the monitoring opportunity offset parameters is one, the terminal uses the same monitoring opportunity offset parameter in the short DRX cycle and the long DRX cycle;
An on-time window, the number of the on-time window parameters may be one or two (see the foregoing embodiment for the case of two), if the number of the on-time window parameters is one, the terminal uses the same on-time window parameter in the short DRX cycle and the long DRX cycle;
control resource sets, the number of which may be one or two (see the foregoing embodiment for the case of two), and if the number of control resource sets is one, the terminal uses the same control resource set in the short DRX cycle and the long DRX cycle;
the number of listening patterns may be one or two (see the foregoing embodiment for the case of two), and if the number of listening patterns is one, the terminal uses the same listening pattern in the short DRX cycle and the long DRX cycle.
Optionally, the base station may additionally configure the time interval of the power saving signal from the DRX cycle to implement the offset of the listening opportunity of the power saving signal. The time interval between the power saving signal and the DRX cycle may be an information field additionally added to the power saving signal search space set configuration information, or may be dedicated parameter configuration of the power saving signal in the base station high-level signaling. The number of the time intervals of the power saving signal from the DRX cycle may be one or two (when the number is two, that is, the "time intervals of the power saving signal from the DRX cycle" respectively corresponding to the short DRX cycle and the long DRX cycle), and if the number of the time intervals of the power saving signal from the DRX cycle is one, the terminal monitors the power saving signal using the same time interval in the short DRX cycle and the long DRX cycle. The listening opportunity offset in the power saving signal search space set configuration information may be defaulted if the base station configures a time interval of the power saving signal from the DRX cycle.
It should be noted that, the above list merely exemplifies several possible cases, and the embodiments of the present application are not limited to the above listed cases.
It should be noted that the configuration of the power-saving signal search space set configuration parameter may be implemented by expanding a PDCCH search space set configuration parameter or multiplexing a PDCCH search space set configuration parameter. The configuration of the above power-saving signal search space set configuration parameters may also be performed independently of the PDCCH search space set configuration procedure.
And the terminal receives PDCCH search space set configuration information sent by the receiving station and monitors the power-saving signal and the PDCCH according to the PDCCH search space set configuration information.
Referring to fig. 3, a schematic diagram of a power saving signal receiving process provided in an embodiment of the present application, where the process may include:
s301: and the terminal receives the power-saving signal search space set configuration information sent by the base station.
The search space set configuration information of the power saving signal comprises first configuration information and/or second configuration information, the first configuration information is the search space set configuration information of the power saving signal used when the terminal is in a short DRX period, and the second monitoring period is the search space set configuration information of the power saving signal used when the terminal is in a long DRX period. The contents and transmission modes of the power saving signal search space set configuration information can be referred to the foregoing embodiments, and are not repeated here.
S302: and the terminal monitors the power saving signal according to the power saving signal search space set configuration information.
The terminal monitors the power saving signal according to the search space set configuration information of the power saving signal, and the following conditions can be included:
case 1: when the terminal is in a short DRX period, monitoring the power saving signal by using first configuration information, and not monitoring the power saving signal when the terminal is in a long DRX period;
case 2: when the terminal is in the long DRX period, monitoring the power saving signal by using the second configuration information, and not monitoring the power saving signal when the terminal is in the short DRX period;

Optionally, the first configuration information includes a first monitoring period, where the first monitoring period is N times of a short DRX period, and N is an integer greater than or equal to zero; the second configuration information includes a second listening period, the second listening period is M times of the long DRX period, and M is an integer greater than or equal to 1. In S302, the terminal monitors the power saving signal using the first listening period when it is in the short DRX cycle in the above cases 1 and 3, and monitors the power saving signal using the second listening period when it is in the long DRX cycle in the above cases 2 and 3.
Optionally, in some embodiments, at least one of the first listening period and the second listening period may be implicitly indicated to the terminal.

It should be noted that the above embodiments on the terminal side may be used independently, or may be combined arbitrarily, and the present application is not limited to this.
In the embodiments of the present application, the configuration of the power saving signal search space set configuration parameters is performed for the short DRX cycle and the long DRX cycle, so that the terminal can flexibly monitor the power saving signal when the short DRX cycle and the long DRX cycle are configured at the same time, and the problem that the time when the power saving signal monitoring opportunity occurs is not matched with the starting point of the active period (on-duration) of the DRX cycle due to the dynamic change of the short DRX cycle and the long DRX cycle is solved.
The following describes in detail the implementation process of the above embodiments of the present application by using several specific examples.
Example 1
The first example describes configuring a search space set including two listening periods and one or two listening opportunity offset values for the power saving signal by the base station.
According to the flow shown in fig. 2, the configuration process of the power saving signal search space set may include: and the base station configures the configuration parameters of the search space set for the power-saving signal through high-level signaling. The monitoring period of the search space set includes a first monitoring period T1 and a second monitoring period T2, the value of the first monitoring period T1 is an integer multiple of the short DRX period, that is, T1 is N × short DRX period length, N is an integer and N is greater than or equal to 0, the value of the second monitoring period T2 is an integer multiple of the long DRX period, that is, T2 is M × long DRX period length, M is an integer and M is greater than or equal to 1. One or two listening opportunity offset values are included in the search space set. If a monitoring opportunity deviation value exists, determining the initial position of the monitoring opportunity of the power-saving signal according to the deviation value for the short DRX period and the long DRX period; if there are two listening opportunity offset values, offset _1 and offset _2, the offset values of the listening opportunities corresponding to the short DRX cycle and the long DRX cycle are different, i.e., the starting position of the listening opportunity of the short DRX cycle is determined according to the offset value, offset _1, and the starting position of the listening opportunity of the long DRX cycle is determined according to the offset value, offset _ 2.
The unit of the first and second listening opportunity offsets offset _1 and offset _2 may be a slot, and the first listening opportunity offset needs to satisfy the following relationship, for example, a certain time interval between the power saving signal and the start time of the first short DRX in the listening period, in units of slots:
Figure BDA0002206146160000271
wherein, Os-DRXFor long DRX cycle start offset, ks-shortDRXFor the short DRX cycle, amod (B) represents performing modulo B mode operation on the a value, offset _1 is the first listening opportunity offset, and offset _ short is the time interval of the power saving signal from the short DRX cycle.
The second listening opportunity offset needs to satisfy the following relationship that a certain time interval is satisfied between the power saving signal and the start time of the first long DRX within the listening period, that is:
Figure BDA0002206146160000281
wherein, Os-DRXOffset _2 is the offset of the second listening opportunity for the long DRX cycle start offset, and offset _ long is the time interval of the power saving signal from the long DRX cycle.
Alternatively, the values of the first and second listening opportunity offsets offset _1 and offset _2 may be the same or different.
Optionally, the offset _ short of the time interval between the power saving signal and the short DRX cycle and the offset _ long of the time interval between the power saving signal and the long DRX cycle may be configured by a high layer signaling, or implicitly indicated by configuring the offset of the monitoring opportunity, that is, the offset _ short and the offset _ long do not need to be configured additionally, and only the offset of the monitoring opportunity and the starting position of the DRX cycle need to satisfy the above relationship.
Other parameters are similar to the parameter configuration of the conventional search space set of PDCCH, and are not described herein again.
The base station sends the power-saving signal according to the configuration of the power-saving signal search space set and the transmission of the terminal data, and the process of sending the power-saving signal may include: the base station acquires the DRX period of the terminal, namely the long DRX period or the short DRX period, according to the DRX period of the terminal and the data arrival condition of the terminal, determines the monitoring opportunity of the power-saving signal (such as the monitoring starting position of the power-saving signal and the time slot length of the continuous monitoring power-saving signal) according to the current DRX period of the terminal and the power-saving signal search space set configuration parameters, and sends the power-saving signal 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 period.
For example, if the current terminal is in the short DRX cycle, that is, the short DRX cycle timer (DRX-ShortCycleTimer) does not time out, the base station transmits the power saving signal at a position corresponding to the listening opportunity offset value offset _1 of the short DRX cycle that needs to be indicated. If the current terminal enters the long DRX period, the base station sends a power saving signal at a position corresponding to the monitoring opportunity offset value offset _2 of the long DRX period required to be indicated. Consistent with conventional PDCCH transmission rules, the base station does not necessarily transmit power-saving signals for the terminal at all listening opportunities.
According to the flow shown in fig. 3, the process of receiving the power saving signal by the terminal may include: and the terminal monitors the power-saving signal according to the monitoring opportunity of the power-saving signal configured by the high-level signaling. Specifically, in the case that the terminal configures a long DRX cycle and a short DRX cycle at the same time, the processing at the terminal side may include:
when the terminal receives the MAC CE carrying the DRX command, starting DRX, then the terminal enters a short DRX period, and starting or restarting a short DRX period timer (DRX-ShortCycleTimer). At this time, the terminal listens to the power saving signal according to the first listening period T1 in the relevant parameters of the search space set configured by the base station. For example, T1 is 2 × short DRX cycle length, the terminal listens for the power saving signal once every 2 short DRX cycles. If there is a listening opportunity offset value offset _1 in the search space set configured by the base station, the position of the candidate power saving signal is determined according to the offset _ 1. If two listener offset values offset _1 and offset _2 are set in the search space configured by the base station, the position of the candidate power saving signal is determined according to offset _ 1.
In the short DRX cycle, the terminal monitors the PDCCH only during the active period. The DRX inactivity timer (DRX-inactivity timer) is started or restarted whenever the terminal receives DCI with a new data indication. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer expires, the terminal uses the short DRX cycle and monitors the PDCCH-based power saving signal with a monitoring opportunity of offset _1 slots before each short DRX cycle with a cycle length of T1.
And when a short DRX period timer (DRX-ShortCycleTimer) is overtime or a MAC CE carrying a long DRX command and transmitted by the base station is received, the terminal enters a long DRX period. For example, T2 is 1 × long DRX cycle, the terminal listens for the power saving signal once every long DRX cycle. If there is one listening opportunity offset value offset _1 in the search space set of the power saving signal, the position of the candidate power saving signal is determined based on the offset _ 1. If there are two listener offset values offset _1 and offset _2 in the search space set of the power saving signal, the position of the candidate power saving signal is determined according to offset _ 2.
When the terminal receives the DCI with the new data indication during the activation of the long DRX cycle, a DRX inactivity timer (DRX-inactivity timer) is turned on or restarted. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer expires, the terminal is in the short DRX cycle and monitors for the power saving signal for a first monitoring period T1.
When the terminal is in the short DRX period and a short DRX period timer (DRX-ShortCycleTimer) is not expired, if the MAC CE with the long DRX command sent by the base station is received, the terminal enters the long DRX period. At this time, the terminal listens for the power saving signal with T2 as a listening period.
Further, the terminal monitors the power saving signal before the active period (on-duration) of the DRX cycle, and performs a subsequent DRX monitoring operation according to the monitored power saving signal. For example, if the terminal receives the power-saving signal at a monitoring opportunity of the power-saving signal, the terminal enters an active state and performs PDCCH monitoring during the subsequent activation of the DRX cycle; otherwise, the terminal continues to be in the inactive state during the subsequent active period of the DRX cycle. The above-mentioned monitoring action of the candidate DRX is only an example, and the embodiment of the present application is not limited to performing other processing operations.
Example two
In example two, the base station configures two search space sets for the power saving signal, where each search space set corresponds to one DRX cycle and one listening opportunity offset value is used as an example for description.
According to the flow shown in fig. 2, the configuration process of the power saving signal search space set may include: the base station configures two search space sets for the power-saving signal through high-level signaling, and the two search space sets are respectively suitable for a long DRX period and a short DRX period. The periods of the monitoring opportunities of the two search space sets of the power saving signal are a first monitoring period T1 and a second monitoring period T2, respectively, where T1 is an integer multiple of the short DRX period, that is, T1 is equal to N × short DRX period length, N is an integer and N is greater than or equal to 0, T2 is an integer multiple of the long DRX period, that is, T2 is equal to M × long DRX period length, M is an integer and M is greater than or equal to 1. Offset values of the two listening opportunities in the search space sets are denoted as offset _1 and offset _2, respectively, and the values of the two offset values may be the same or different. Other parameters of the search space set are similar to the parameter configuration of the search space set of the conventional PDCCH, and are not described herein again.
The base station sends the power-saving signal according to the configuration of the power-saving signal search space set and the transmission of the terminal data, and the process of sending the power-saving signal may include: the base station learns the DRX cycle of the terminal, namely the long DRX cycle or the short DRX cycle, according to the DRX configuration information and the data arrival condition of the terminal, determines the monitoring opportunity of the power-saving signal (such as the monitoring starting position of the power-saving signal and the time slot length of the continuous monitoring power-saving signal) according to the current DRX cycle of the terminal and the power-saving signal search space set configuration parameters, and sends the power-saving signal at the monitoring opportunity of the power-saving signal so as to indicate whether the terminal wakes up from the dormant state to monitor the PDCCH or continue to sleep in the subsequent DRX.
According to the flow shown in fig. 3, the process of receiving the power saving signal by the terminal may include: and the terminal monitors the power-saving signal according to the monitoring opportunity of the power-saving signal configured by the high-level signaling. Specifically, in the case that the terminal configures a long DRX cycle and a short DRX cycle at the same time, the processing at the terminal side may include:
when the terminal receives the MAC CE carrying the DRX command, starting DRX, then the terminal enters a short DRX period, and starting or restarting a DRX period timer (DRX-ShortCycleTimer). At this time, the terminal listens to the power saving signal according to a first listening period T1 in the relevant parameters of the power saving signal search space set configured by the higher layer signaling, for example, T1 ═ 2 × short DRX cycle length, and the terminal listens to the power saving signal once every 2 short DRX cycles. The candidate power saving signal is located at offset _1 slots before the active period (on-duration) of the short DRX cycle.
In the short DRX cycle, the terminal monitors the PDCCH only during the active period. The DRX inactivity timer (DRX-inactivity timer) is started or restarted whenever the terminal receives DCI with a new data indication. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer expires, the terminal uses the short DRX cycle and performs monitoring of the PDCCH-based power saving signal with a monitoring opportunity of offset _1 slots before each short DRX cycle with a period of T1.
When a short DRX period timer (DRX-ShortCycleTimer) is overtime or receives a MAC CE carrying a long DRX command sent by a base station, the terminal enters a long DRX period. For example, T2 is 1 × long DRX cycle length, the terminal listens to the power saving signal once per long DRX cycle, and specifically, the terminal starts listening opportunities at offset — 2 slot positions before each long DRX cycle. And if the terminal receives the DCI with the new data indication during the activation period of the long DRX, starting or restarting a DRX inactivity timer (DRX-inactivity timer). When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer expires, the terminal is in the short DRX cycle and monitors for the power saving signal at a monitoring period T1.
When the terminal is in the short DRX period and a short DRX period timer (DRX-ShortCycleTimer) is not expired, if the MAC CE with the long DRX command sent by the base station is received, the terminal enters the long DRX period. At this time, the terminal listens for the power saving signal with T2 as a listening period.
Further, the terminal monitors the power saving signal before the active period (on-duration) of the DRX cycle, and performs a subsequent DRX monitoring operation according to the monitored power saving signal. For example, if the terminal receives the power-saving signal at a monitoring opportunity of the power-saving signal, the terminal enters an active state and performs PDCCH monitoring during the subsequent activation of the DRX cycle; otherwise, the terminal continues to be in an inactive state during the subsequent active period of the DRX cycle. The above-mentioned monitoring action of the candidate DRX is only an example, and the embodiment of the present application is not limited to performing other processing operations.
Example three
In the third example, the base station configures a search space set for the power saving signal, where the search space set includes two listening periods and two listening time windows.
According to the flow shown in fig. 2, the process of configuring the power-saving signal search space set may include: and the base station configures the configuration parameters of the search space set for the power-saving signal through high-level signaling. The search space set comprises two monitoring periods, namely a first monitoring period T1 and a second monitoring period T2, wherein the value of T1 is an integral multiple of the short DRX period, namely T1 is equal to N multiplied by the length of the short DRX period, N is an integer and N is larger than or equal to 0, the value of T2 is an integral multiple of the long DRX period, namely T2 is equal to M multiplied by the length of the long DRX period, and M is an integer and is larger than or equal to 1. In this embodiment, N is 2 and M is 1. Meanwhile, two monitoring time windows are centrally configured in the search space: the first duration _1 and the second duration _2 of the listening time window correspond to the short DRX cycle and the long DRX cycle, respectively, i.e. the duration _1 of the listening time window of the short DRX cycle and the duration _2 of the listening time window of the long DRX cycle. The values of the two time windows may be the same or different. If the two time windows are the same, the implementation process is the same as that of the first example, and the embodiment takes the difference in the lengths of the two time windows as an example, such as: when the terminal is in the short DRX period, the power saving signal carries power saving information of 2 short DRX periods; when the terminal is in the long DRX cycle, the power saving signal carries power saving information for 1 long DRX cycle, and the base station can configure the value of duration _1 to be 3 slots and the value of duration _2 to be 2 slots. Other parameters are similar to the parameter configuration of the conventional search space set of PDCCH, and are not described herein again.
The base station may transmit the power-saving signal according to the configuration of the power-saving signal search space set and the transmission of the terminal data, and the process may include: the base station learns the DRX period of the terminal, namely the long DRX period or the short DRX period, according to the DRX period of the terminal and the data arrival condition of the terminal, determines the monitoring opportunity of the power-saving signal (such as the monitoring starting position of the power-saving signal and the time slot length of the continuous monitoring power-saving signal) according to the current DRX period of the terminal and the power-saving signal search space set configuration parameters, and sends the power-saving signal at the monitoring opportunity of the power-saving signal so as to indicate whether the terminal wakes up from a sleep state to monitor the PDCCH or continues to sleep in the subsequent DRX period.
For example, if the current terminal is in the short DRX cycle, that is, when the short DRX cycle timer (DRX-ShortCycleTimer) does not time out, the base station sends the power saving signal at the position corresponding to the listening offset value offset of the first short DRX cycle with the listening cycle T1 in the short DRX cycle that needs to be indicated, and continues to send duration — 1 slots. And if the current terminal enters the long DRX period, the base station sends a power-saving signal at a position corresponding to the monitoring offset value offset of the long DRX period needing to be indicated, and continuously sends duration-2 time slots. Consistent with conventional PDCCH transmission rules, the base station does not necessarily transmit power-saving signals for the terminal at all monitoring opportunities.
According to the flow shown in fig. 3, the process of receiving the power saving signal by the terminal may include: and the terminal monitors the power-saving signal according to the monitoring opportunity of the power-saving signal configured by the high-level signaling. Specifically, in the case that the terminal configures a long DRX cycle and a short DRX cycle at the same time, the processing at the terminal side may include:
and if the terminal receives the MAC CE carrying the DRX command, starting DRX, entering a short DRX period by the terminal, and starting or restarting a short DRX period timer (DRX-ShortCycleTimer). At this time, the terminal listens for the power saving signal according to the first listening period T1 in the relevant parameters of the search space set of the power saving signal configured by the higher layer signaling. For example, when T1 is 2 × short DRX cycle length, the terminal monitors the power saving signal once every 2 short DRX cycles, specifically, the terminal monitors the power saving signal at a position corresponding to the monitoring offset value offset of the first short DRX cycle, and the power saving signal monitors duration — 1 slots.
In the short DRX cycle, the terminal monitors the PDCCH only during the active period. The DRX inactivity timer (DRX-inactivity timer) is started or restarted whenever the terminal receives DCI with a new data indication. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer is overtime, the terminal uses the short DRX cycle, and with the monitoring cycle as T1, monitors the power saving signal at the position corresponding to the monitoring offset value offset of the first short DRX cycle, and monitors the duration — 1 slots.
When a short DRX period timer (DRX-ShortCycleTimer) is overtime or receives a MAC CE carrying a long DRX command sent by a base station, the terminal enters a long DRX period. For example, if T2 is 1 × long DRX cycle length, the terminal monitors the power saving signal once per long DRX cycle, and more specifically, the terminal monitors the power saving signal at a position corresponding to the monitor offset value offset per long DRX cycle, and the power saving signal monitors the duration _2 slots. If the terminal receives the DCI with the new data indication during the activation of the long DRX, a DRX inactivity timer (DRX-inactivity timer) is turned on or restarted. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer is overtime, the terminal is in the short DRX cycle, monitors the power saving signal with the monitoring cycle T1, the power saving signal is located at the position corresponding to the monitoring offset value offset of one short DRX cycle of the monitoring cycle, and the power saving signal monitors the duration _1 slots.
When the terminal is in the short DRX period and a short DRX period timer (DRX-ShortCycleTimer) is not expired, if the MAC CE with the long DRX command sent by the base station is received, the terminal enters the long DRX period. At this time, the terminal monitors the power saving signal with T2 as the monitoring period, that is, the power saving signal is located at the position corresponding to the monitor offset value offset of each long DRX cycle, and monitors the duration _2 slots.
Further, the terminal monitors the power saving signal before the active period (on-duration) of the DRX cycle, and performs a subsequent DRX monitoring operation according to the monitored power saving signal. For example, if the terminal receives the power-saving signal at a monitoring opportunity of the power-saving signal, the terminal enters an active state and performs PDCCH monitoring during the subsequent activation of the DRX cycle; otherwise, the terminal continues to be in an inactive state during the subsequent active period of the DRX cycle. The above-mentioned monitoring action of the candidate DRX is only an example, and the embodiment of the present application is not limited to performing other processing operations.
Example four
In the fourth example, the base station configures a search space set for the power saving signal, where the search space set includes two listening periods and two control resource sets as an example.
According to the flow shown in fig. 2, the configuration process of the power saving signal search space set may include: and the base station configures the configuration parameters of the search space set for the power-saving signal through high-level signaling. The search space set has two monitoring periods, namely a first monitoring period T1 and a second monitoring period T2, wherein the value of the first monitoring period T1 is an integer multiple of the short DRX period, that is, T1 is equal to N × short DRX period length, N is an integer and N is equal to or greater than 0, the value of T2 is equal to an integer multiple of the long DRX period, that is, T2 is equal to M × long DRX period length, M is an integer and M is equal to or greater than 1. In this embodiment, N is 2 and M is 1.
Configuring two control resource sets associated with the search space set in the search space set: the first control resource set CORESET _1 and the second control resource set CORESET _2 respectively correspond to the short DRX cycle and the long DRX cycle, that is, the control resource set of the short DRX cycle is the first control resource set CORESET _1, and the control resource set of the long DRX cycle is the second control resource set CORESET _ 2. The two control resource sets may be the same or different. If the two are the same, the implementation process is the same as that of example one, and the embodiment takes the difference between the two as an example, for example: when the terminal is in a short DRX period, a first control resource set CORESET _1 occupies three symbols in a time domain; when the terminal is in the long DRX cycle, the second control resource set CORESET _2 occupies two symbols in the time domain. Optionally, the CORESET where the long DRX cycle and the short DRX cycle are located may also occupy different frequency domain resources. Other parameters are similar to the parameter configuration of the conventional search space set of PDCCH, and are not described herein again.
The base station sends the power-saving signal according to the configuration of the power-saving signal search space set and the transmission of the terminal data, and the process of sending the power-saving signal may include: the base station learns the DRX period of the terminal, namely the long DRX period or the short DRX period, according to the DRX period of the terminal and the data arrival condition of the terminal, determines the monitoring opportunity of the power-saving signal (such as the monitoring starting position of the power-saving signal and the time slot length of the continuous monitoring power-saving signal) according to the current DRX period of the terminal and the power-saving signal search space set configuration parameters, and sends the power-saving signal at the monitoring opportunity of the power-saving signal so as to indicate whether the terminal wakes up from a sleep state to monitor the PDCCH or continues to sleep in the subsequent DRX period.
For example: if the current terminal is in the short DRX cycle, that is, the short DRX cycle timer (DRX-ShortCycleTimer) is not expired, the base station sends a power saving signal at a position corresponding to the offset value offset of the first short DRX cycle with the monitoring cycle T1 in the short DRX cycle that needs to be indicated, where the resource set where the power saving signal is located is the first control resource set CORESET _ 1. If the current terminal enters the long DRX period, the base station sends a power saving signal at a position corresponding to the monitoring offset value offset of the long DRX period needing to be indicated, and the resource set where the power saving signal is located is a second control resource set CORESET _ 2. Consistent with conventional PDCCH transmission rules, the base station does not necessarily transmit power-saving signals for the terminal at all monitoring opportunities.
According to the flow shown in fig. 3, the process of receiving the power saving signal by the terminal may include: and the terminal monitors the power-saving signal according to the monitoring opportunity of the power-saving signal configured by the high-level signaling. Specifically, in the case that the terminal configures a long DRX cycle and a short DRX cycle at the same time, the processing at the terminal side may include:
and if the terminal receives the MAC CE carrying the DRX command, starting DRX, entering a short DRX period by the terminal, and starting or restarting a short DRX period timer (DRX-ShortCycleTimer). At this time, the terminal listens for the power saving signal according to the first listening period T1 in the relevant parameters of the search space set of the power saving signal configured by the higher layer signaling. For example, if T1 is 2 × short DRX cycle length, the terminal monitors the power saving signal once every 2 short DRX cycles, specifically, the terminal monitors the power saving signal at a position corresponding to the monitoring offset value offset of the first short DRX cycle, and the resource set of the power saving signal is the first control resource set CORESET _ 1.
In the short DRX cycle, the terminal monitors the PDCCH only during the active period. And starting or restarting a timer inactivity timer (drx-inactivity timer) each time the terminal receives the DCI with the new data indication. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer is overtime, the terminal adopts a short DRX cycle, and with the monitoring cycle being T1, monitors the power saving signal at the position corresponding to the monitoring offset value offset of the first short DRX cycle, where the resource set of the power saving signal is the first control resource set CORESET _ 1.
And when the short DRX period timer (DRX-ShortCycleTimer) is overtime or the MAC CE carrying the long DRX command sent by the base station is received, the terminal enters the long DRX period. For example, if T2 is 1 × long DRX cycle, the terminal monitors the power saving signal once every long DRX cycle, specifically, the terminal monitors the power saving signal at a position corresponding to the monitoring offset value offset of every long DRX cycle, and the resource set of the power saving signal is the second control resource set CORESET _ 2. And if the terminal receives the DCI with the new data indication during the activation period of the long DRX, starting or restarting a DRX inactivity timer (DRX-inactivity timer). When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer is overtime, the terminal is in the short DRX cycle, the terminal monitors the power saving signal with a monitoring cycle T1, the power saving signal is located at a position corresponding to the monitoring offset value offset of one short DRX cycle of the monitoring cycle, and the resource set in which the power saving signal monitors is the first control resource set CORESET _ 1.
When the terminal is in a short DRX period and a short DRX period timer (DRX-ShortCycleTimer) is not timed out, and a MAC CE with a long DRX command sent by a base station is received, the terminal enters the long DRX period. At this time, the terminal monitors the power saving signal with T2 as the monitoring period, that is, the power saving signal is located at the position corresponding to the monitoring offset value offset of each long DRX period, and the resource set in which the power saving signal is located is the second control resource set CORESET _ 2.
Further, the terminal monitors the power saving signal before the active period (on-duration) of the DRX cycle, and performs a subsequent DRX monitoring operation according to the monitored power saving signal. For example, if the terminal receives the power-saving signal at a monitoring opportunity of the power-saving signal, the terminal enters an active state and performs PDCCH monitoring during the activation of a subsequent DRX cycle; otherwise, the terminal continues to be in the inactive state during the subsequent active period of the DRX cycle. The above-mentioned monitoring action of the candidate DRX is only an example, and the embodiment of the present application is not limited to performing other processing operations.
Example five
In the fifth example, the base station configures a search space set for the power saving signal, where the search space set includes two listening periods and two listening patterns are described as an example.
According to the flow shown in fig. 2, the configuration process of the power saving signal search space set may include: and the base station configures configuration parameters of the search space set for the power-saving signals through high-level signaling. There are two listening periods of the search space set, a first listening period T1 and a second listening period T2. The value of T1 is an integer multiple of the short DRX cycle, i.e., T1 is N × the short DRX cycle length, N is an integer and N is equal to or greater than 0, and T2 is an integer multiple of the long DRX cycle, i.e., T2 is M × the long DRX cycle length, and M is an integer and M is equal to or greater than 1. In this embodiment, N is 2 and M is 1.
Two listening patterns are configured in the search space set: the first and second monitoring patterns pattern _1 and pattern _2 correspond to a short DRX cycle and a long DRX cycle, respectively, that is, the monitoring pattern of the short DRX cycle is the first monitoring pattern _1, and the monitoring pattern of the long DRX cycle is the second monitoring pattern _ 2. The two listening patterns may be the same or different. If the difference is the same as the implementation process of the first example, the embodiment takes the difference as an example. For example, the monitoring pattern corresponding to the power saving signal in the short DRX cycle is the first monitoring as shown in pattern _1, and the time domain resources described by the pattern are: the initial symbol is the first symbol, CORESET occupies three symbols, and when the terminal is in a short DRX cycle, the symbols occupied by the power saving signal in one time slot are {1, 2, 3 }. The monitoring pattern of the power saving signal in the long DRX cycle is a second monitoring pattern _2, and the pattern describes time-frequency resources as follows: the initial symbol is the 4 th symbol, CORESET occupies three symbols, and when the terminal is in a long DRX cycle, the symbols occupied by the power saving signal in one time slot are {4, 5, 6 }. Other parameters are similar to the parameter configuration of the conventional search space set of the PDCCH, and are not described herein again.
The base station may transmit the power-saving signal according to the configuration of the power-saving signal search space set and the transmission of the terminal data, and the process may include: the base station acquires the DRX period of the terminal, namely the long DRX period or the short DRX period, according to the DRX period of the terminal and the data arrival condition of the terminal, determines the monitoring opportunity of the power-saving signal (such as the monitoring starting position of the power-saving signal and the time slot length of the continuous monitoring power-saving signal) according to the current DRX period of the terminal and the power-saving signal search space set configuration parameters, and sends the power-saving signal 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 period.
For example, if the current terminal is in the short DRX cycle, that is, when the short DRX cycle timer (DRX-ShortCycleTimer) is not timed out, the base station sends the power saving signal at a position corresponding to the offset value offset of the first short DRX cycle with the monitoring cycle T1 in the short DRX cycle that needs to be indicated, where the monitoring pattern is a first monitoring pattern _ 1. And if the current terminal enters the long DRX period, the base station sends a power-saving signal at a position corresponding to the monitoring offset value offset of the long DRX period needing to be indicated, and the monitoring pattern is a second monitoring pattern _ 2. Consistent with conventional PDCCH transmission rules, the base station does not necessarily transmit power-saving signals for the terminal at all listening opportunities.
According to the flow shown in fig. 3, the process of receiving the power saving signal by the terminal may include: and the terminal monitors the power-saving signal according to the monitoring opportunity of the power-saving signal configured by the high-level signaling. Specifically, in the case that the terminal configures a long DRX cycle and a short DRX cycle at the same time, the processing at the terminal side may include:
and if the terminal receives the MAC CE carrying the DRX command, starting DRX, entering a short DRX period by the terminal, and starting or restarting a short DRX period timer (DRX-ShortCycleTimer). At this time, the terminal monitors the power saving signal according to a first monitoring period T1 in the relevant parameters of the search space set of the power saving signal configured by the higher layer signaling, and if T1 is 2 × short DRX cycle, the terminal monitors the power saving signal once every 2 short DRX cycles, specifically, the terminal monitors the power saving signal at a position corresponding to the monitoring offset value offset of the first short DRX cycle, and the monitoring pattern of the power saving signal is a first monitoring pattern _ 1.
In the short DRX period, the monitoring of the PDCCH is only carried out in the active period. The inactivity timer (drx-inactivity timer) is started or restarted each time the terminal receives DCI with a new data indication. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer is overtime, the terminal uses the short DRX cycle, and with the monitoring cycle as T1, monitors the power saving signal at the position corresponding to the monitoring offset value offset of the first short DRX cycle, where the monitoring pattern of the power saving signal is the first monitoring pattern _ 1.
When a short DRX period timer (DRX-ShortCycleTimer) is overtime or receives a MAC CE carrying a long DRX command sent by a base station, the terminal enters a long DRX period. For example, if T2 is 1 × long DRX cycle, the terminal monitors the power saving signal once every long DRX cycle, and specifically, the terminal monitors the power saving signal at a position corresponding to the monitor offset value offset of every long DRX cycle, where the monitor pattern of the power saving signal is the second monitor pattern _ 2. If the terminal receives the DCI with the new data indication during the activation of the long DRX, a DRX inactivity timer (DRX-inactivity timer) is turned on or restarted. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer is overtime, the terminal is in the short DRX cycle, and monitors the power saving signal with a monitoring cycle T1, where the power saving signal is located at a position corresponding to the monitoring offset value offset of one short DRX cycle of the monitoring cycle, and the monitoring pattern of the power saving signal is the first monitoring pattern _ 1.
And when the terminal is in the short DRX period and a short DRX period timer (DRX-ShortCycleTimer) is not expired, the terminal enters the long DRX period when receiving the MAC CE with the long DRX command sent by the base station. At this time, the terminal monitors the power saving signal with T2 as the monitoring period, that is, the power saving signal is located at the position corresponding to the monitoring offset value offset of each long DRX period, and the monitoring pattern of the power saving signal is the second monitoring pattern _ 2.
Further, the terminal monitors the power saving signal before the active period (on-duration) of the DRX cycle, and performs a subsequent DRX monitoring operation according to the monitored power saving signal. For example, if the terminal receives the power-saving signal at a monitoring opportunity of the power-saving signal, the terminal enters an active state and performs PDCCH monitoring during the subsequent activation of the DRX cycle; otherwise, the terminal continues to be in an inactive state during the subsequent active period of the DRX cycle. The above-mentioned monitoring action of the candidate DRX is only an example, and the embodiment of the present application is not limited to performing other processing operations.
Example six
Example six is described by configuring a search space set for the power saving signal by the base station, wherein the search space set comprises one or two listening periods, and the time interval of the power saving signal from the DRX period is implicitly indicated by the listening opportunity offset.
The configuration process of the power saving signal search space set may include: and the base station configures the configuration parameters of the search space set for the power-saving signal through high-level signaling. Wherein the listening period of the search space set may include a first listening period T1 and a second listening period T2; only the second listening period T2 may be included. The first monitoring period T1 is an integer multiple of the short DRX cycle, i.e. T1 is N × short DRX cycle length, N is an integer and N is greater than or equal to 0, and the second monitoring period T2 is an integer multiple of the long DRX cycle, i.e. T2 is M × long DRX cycle length, M is an integer and M is greater than or equal to 1.
One or two listening opportunity offset values are included in the search space set. If a monitoring opportunity deviation value exists, determining the initial position of the monitoring opportunity of the power-saving signal according to the deviation value for the short DRX period and the long DRX period; if there are two listening opportunity offset values, offset _1 and offset _2, the offset values of the listening opportunities corresponding to the short DRX cycle and the long DRX cycle are different, i.e., the starting position of the listening opportunity of the short DRX cycle is determined according to the offset value, offset _1, and the starting position of the listening opportunity of the long DRX cycle is determined according to the offset value, offset _ 2.
The unit of the first and second listening opportunity offsets offset _1 and offset _2 may be a slot, and for example, the following relationship needs to be satisfied between the first listening opportunity offset and the start point of the first DRX cycle in the listening period, that is, a certain time interval is satisfied between the power saving signal and the start time of the first short DRX in the listening period:
Figure BDA0002206146160000411
wherein, Os-DRXFor long DRX cycle start offset, ks-shortDRXFor the short DRX cycle, amod (B) represents performing modulo B mode operation on the a value, offset _1 is the first listening opportunity offset, and offset _ short is the time interval of the power saving signal from the short DRX cycle.
The second listening opportunity offset and the start point of the neighboring long DRX cycle need to satisfy the following relationship, that is, a certain time interval is satisfied between the power saving signal and the start time of the first long DRX within the listening cycle:
Figure BDA0002206146160000412
wherein, Os-DRXOffset _2 is the offset of the second listening opportunity for the long DRX cycle start offset, and offset _ long is the time interval of the power saving signal from the long DRX cycle.
The values of the first and second listener offset _1 and offset _2 may be the same or different.
The time interval offset _ short of the power saving signal from the short DRX cycle and the time interval offset _ long of the power saving signal from the long DRX cycle are parameters related to the user capability, and here, implicit indication is performed by configuring the offset of the monitoring opportunity, that is, the base station does not need to additionally configure the offset _ short and the offset _ long, and only the offset of the monitoring opportunity and the initial position of the DRX cycle need to satisfy the above relationship.
Other parameters are similar to the parameter configuration of the conventional search space set of PDCCH, and are not described herein again.
The base station sends the power-saving signal according to the configuration of the power-saving signal search space set and the transmission of the terminal data, and the process of sending the power-saving signal may include: the base station learns the DRX period of the terminal, namely the long DRX period or the short DRX period, according to the DRX period of the terminal and the data arrival condition of the terminal, determines the monitoring opportunity of the power-saving signal (such as the monitoring starting position of the power-saving signal and the time slot length of the continuous monitoring power-saving signal) according to the current DRX period of the terminal and the power-saving signal search space set configuration parameters, and sends the power-saving signal at the monitoring opportunity of the power-saving signal so as to indicate whether the terminal wakes up from a sleep state to monitor the PDCCH or continues to sleep in the subsequent DRX period.
For example, for the case where the first listening period T1 and the second listening period T2 are configured in the search space set, the procedure of the terminal listening for the power saving signal is the same as the first embodiment. For the case that only the second DRX cycle T2 is configured in the search space set, the base station only sends the power-saving signal at the position corresponding to the listening opportunity offset value offset _2 before every M (M is an integer and M ≧ 1) long DRX cycles.
The process of the terminal receiving the power saving signal may include: and the terminal monitors the power-saving signal according to the monitoring opportunity of the power-saving signal configured by the high-level signaling. Specifically, in the case that the terminal configures a long DRX cycle and a short DRX cycle at the same time, the processing at the terminal side may include:
for the case that the first listening period T1 and the second listening period T2 are configured in the search space set, the process of the terminal listening for the power saving signal is the same as the first embodiment.
For the case that only the second monitoring period T2 is configured in the search space set, the terminal monitors the candidate power saving signal only before the long DRX period, every M (M is an integer and M ≧ 1) long DRX periods, corresponding to the position of the offset value of monitoring opportunity offset _ 2.
When the terminal receives the MAC CE carrying the DRX command, starting DRX, then the terminal enters a short DRX period, and starting or restarting a short DRX period timer (DRX-ShortCycleTimer). At this time, since only the second monitoring period T2 is included in the relevant parameters of the search space set configured by the base station, according to the configuration, the terminal does not monitor the power saving signal in the short DRX cycle, and monitors the PDCCH in the active period of each short DRX cycle.
The DRX inactivity timer (DRX-inactivity timer) is started or restarted whenever the terminal receives DCI with a new data indication. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer is overtime, the terminal adopts a short DRX period and does not monitor the power-saving signal.
And when a short DRX period timer (DRX-ShortCycleTimer) is overtime or a MAC CE carrying a long DRX command and transmitted by the base station is received, the terminal enters a long DRX period. For example, T2 is 1 × long DRX cycle, the terminal listens for the power saving signal once every long DRX cycle. The position of the candidate power saving signal is determined according to offset _ 2.
When the terminal receives the DCI with the new data indication during the activation of the long DRX cycle, a DRX inactivity timer (DRX-inactivity timer) is turned on or restarted. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer is overtime, the terminal is in a short DRX period, and the terminal does not monitor the power saving signal any more.
When the terminal is in the short DRX period and a short DRX period timer (DRX-ShortCycleTimer) is not expired, if the MAC CE with the long DRX command sent by the base station is received, the terminal enters the long DRX period. At this time, the terminal listens for the power saving signal in the listening period T2, and the position of the candidate power saving signal is determined based on offset _ 2.
Further, the terminal monitors the power saving signal before the active period (on-duration) of the DRX cycle, and performs a subsequent DRX monitoring operation according to the monitored power saving signal. For example, if the terminal receives the power-saving signal at a monitoring opportunity of the power-saving signal, the terminal enters an active state and performs PDCCH monitoring during the subsequent activation of the DRX cycle; otherwise, the terminal continues to be in an inactive state during the subsequent active period of the DRX cycle. The above-mentioned monitoring action of the candidate DRX is only an example, and the embodiment of the present application is not limited to performing other processing operations.
Example seven
The seventh example is described by taking the base station as an example to configure a search space set for the power saving signal, where the search space set includes one or two listening periods, and explicitly indicating the time interval of the power saving signal from the DRX period through high-layer signaling.
The configuration process of the power saving signal search space set may include: and the base station configures the configuration parameters of the search space set for the power-saving signal through high-level signaling. Wherein the listening period of the search space set may include a first listening period T1 and a second listening period T2; only the second listening period T2 may be included. The first monitoring period T1 is an integer multiple of the short DRX cycle, i.e. T1 is N × short DRX cycle length, N is an integer and N is greater than or equal to 0, and the second monitoring period T2 is an integer multiple of the long DRX cycle, i.e. T2 is M × long DRX cycle length, M is an integer and M is greater than or equal to 1.
And the base station indicates the monitoring position of the power saving signal in each monitoring period through the time interval of the power saving signal from the DRX period. The base station needs to configure one or two time intervals of the power saving signal to the DRX period for the terminal, wherein:
1. configuring one listening interval offset _ gap means that the power saving signal is located at the same position before the active period of the DRX cycle regardless of the long DRX cycle or the short DRX cycle;
2. two listening time intervals, offset _ long and offset _ short, are configured, and correspond to the time interval between the power saving signal and the long DRX cycle and the time interval between the power saving signal and the short DRX cycle, respectively. The values of the two time intervals may be the same or different.
Here, the time interval between the power saving signal and the DRX cycle may be an information field additionally added to the power saving signal search space set configuration information, or may be a parameter configuration specific to the power saving signal in the base station high-level signaling.
Other parameters are similar to the parameter configuration of the conventional search space set of PDCCH, and are not described herein again.
The base station sends the power-saving signal according to the configuration of the power-saving signal search space set and the transmission of the terminal data, and the process of sending the power-saving signal may include: the base station learns the DRX period of the terminal, namely the long DRX period or the short DRX period, according to the DRX period of the terminal and the data arrival condition of the terminal, determines the monitoring opportunity of the power-saving signal (such as the monitoring starting position of the power-saving signal and the time slot length of the continuous monitoring power-saving signal) according to the current DRX period of the terminal and the power-saving signal search space set configuration parameters, and sends the power-saving signal at the monitoring opportunity of the power-saving signal so as to indicate whether the terminal wakes up from a sleep state to monitor the PDCCH or continues to sleep in the subsequent DRX period.
The process of the terminal receiving the power saving signal may include: and the terminal monitors the power-saving signal according to the monitoring opportunity of the power-saving signal configured by the high-level signaling. Specifically, in the case that the terminal configures a long DRX cycle and a short DRX cycle at the same time, the processing at the terminal side may include:
for the case that the first monitoring period T1 and the second monitoring period T2 are configured in the search space set, the terminal monitors the power saving signal in the short DRX cycle or the long DRX cycle according to the monitoring period of the power saving signal configured by the base station, and the monitoring process is the same as that in the first embodiment. In particular, the terminal needs to calculate the offset O of the listening opportunity of the power saving signal according to the time interval of the power saving signal from the DRX cycle1And O2. The time interval of the power saving signal from the DRX period, the short DRX period and the initial offset of the long DRX period need to satisfy a certain relation, which means that the monitoring position of the power saving signal needs to be separated from the first DRX initial time in the power saving signal monitoring period by a certain time interval, namely the time interval offset of the power saving signal from the DRX period configured by the base stationlongAnd offsetshort：

If the base station only configures one time interval, the power saving signal only needs to satisfy the following relation in the long DRX period and the short DRX period:
Figure BDA0002206146160000453
Figure BDA0002206146160000454
for the case that only the second monitoring period T2 is configured in the search space set, the base station monitors the opportunity offset value O only before every M (M is an integer and M is more than or equal to 1) long DRX periods2And transmitting the power saving signal at the corresponding position. Wherein the listener offset value O2The following relationship is required, that is, the time interval of the power saving signal from the start time of the first long DRX cycle in the power saving signal listening period satisfies the following relationship:

wherein, Os-DRXFor long DRX cycle start offset, ks-longDRXFor long DRX cycles, Amod (B) denotes performing modulo-B mode operations on the A value, OsOffset is monitored opportunity offset of the power saving signal corresponding to the long DRX period, and offset _ gap is time interval of the power saving signal from the DRX period.
When the terminal receives the MAC CE carrying the DRX command, starting DRX, then the terminal enters a short DRX period, and starting or restarting a short DRX period timer (DRX-ShortCycleTimer). At this time, if the base station configures the first listening period T1, the terminal listens for the candidate power saving signal according to the relevant parameters of the search space set configured by the base station. For example, T1 is 2 × short DRX cycle length, the terminal listens for the power saving signal once every 2 short DRX cycles. If the base station configures a listening interval offset _ gap, the terminal determines the position of the candidate power saving signal according to the time interval offset _ gap calculation. If the base station configures two listening time intervals, offset _ long and offset _ short, the terminal determines the position of the candidate power saving signal according to the listening time interval, offset _ short. If the base station does not configure the first listening period T1 for the short DRX cycle, the terminal does not perform power saving signal listening for the short DRX cycle.
In the short DRX cycle, the terminal monitors the PDCCH only during the active period. The DRX inactivity timer (DRX-inactivity timer) is started or restarted whenever the terminal receives DCI with a new data indication. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer expires, the terminal adopts a short DRX cycle. If the base station configures the first listening period T1, the terminal calculates the position of the candidate power saving signal according to the time interval offset _ gap configured by the base station with the length of the listening period T1, and performs power saving signal listening. If the base station configures two listening time intervals, offset _ long and offset _ short, the terminal determines the position of the candidate power saving signal according to the listening time interval, offset _ short. If the base station does not configure the first listening period T1 for the short DRX cycle, the terminal does not perform power saving signal listening for the short DRX cycle.
And when a short DRX period timer (DRX-ShortCycleTimer) is overtime or a MAC CE carrying a long DRX command and transmitted by the base station is received, the terminal enters a long DRX period. For example, T2 is 1 × long DRX cycle, the terminal listens for the power saving signal once every long DRX cycle. If the base station configures a listening interval offset _ gap, the terminal determines the position of the candidate power saving signal according to the time interval offset _ gap calculation. If the base station configures two listening time intervals, offset _ long and offset _ short, the terminal determines the position of the candidate power saving signal according to the listening time interval, offset _ long.
When the terminal receives the DCI with the new data indication during the activation of the long DRX cycle, a DRX inactivity timer (DRX-inactivity timer) is turned on or restarted. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer expires, the terminal is in a short DRX cycle. If the base station configures the first listening period T1, the terminal calculates the position of the candidate power saving signal according to the time interval offset _ gap configured by the base station with the length of the listening period T1, and performs power saving signal listening. If the base station configures two listening time intervals, offset _ long and offset _ short, the terminal determines the position of the candidate power saving signal according to the listening time interval, offset _ short. If the base station does not configure the first listening period T1 for the short DRX cycle, the terminal does not perform power saving signal listening for the short DRX cycle.
When the terminal is in the short DRX period and a short DRX period timer (DRX-ShortCycleTimer) is not expired, if the MAC CE with the long DRX command sent by the base station is received, the terminal enters the long DRX period. For example, T2 ═ 1 × long DRX cycle, and the terminal listens to the power saving signal once every long DRX cycle. If the base station configures a listening interval offset _ gap, the terminal determines the position of the candidate power saving signal according to the time interval offset _ gap calculation. If the base station configures two listening time intervals, offset _ long and offset _ short, the terminal determines the position of the candidate power saving signal according to the listening time interval, offset _ long.
Further, the terminal monitors the power saving signal before the active period (on-duration) of the DRX cycle, and performs a subsequent DRX monitoring operation according to the monitored power saving signal. For example, if the terminal receives the power-saving signal at a monitoring opportunity of the power-saving signal, the terminal enters an active state and performs PDCCH monitoring during the subsequent activation of the DRX cycle; otherwise, the terminal continues to be in an inactive state during the subsequent active period of the DRX cycle. The above-mentioned monitoring action of the candidate DRX is only an example, and the embodiment of the present application is not limited to performing other processing operations.
Example eight
The eighth example is described by taking the power saving signal transmitted only within one CORESET, and the base station does not configure the search space set for the power saving signal, but explicitly indicates the time interval of the power saving signal from the DRX cycle through high layer signaling.
When the power saving signal is associated with DRX cycles, i.e. the power saving signal is received before each DRX active period, or only before each active period of a long DRX cycle, then the base station may not configure the terminal with the monitoring period of the power saving signal, and is implicitly indicated by the DRX cycle. In this case, the base station only needs to configure the terminal with the time interval of the power saving signal from the DRX cycle for indicating the listening position of the power saving signal. The following conditions are specific:
1. If the power saving signal needs to be received before each DRX cycle active period, including a short DRX cycle and a long DRX cycle, the base station needs to configure the terminal with one or two time intervals of the power saving signal from the DRX cycle, where:
a) configuring one listening interval offset _ gap means that the power saving signal is located at the same position before the active period of the DRX cycle regardless of the long DRX cycle or the short DRX cycle;
b) two listening time intervals, offset _ long and offset _ short, are configured, and correspond to the time interval between the power saving signal and the long DRX cycle and the time interval between the power saving signal and the short DRX cycle, respectively.
2. If the power saving signal only needs to be received before each long DRX cycle active period, the base station only needs to configure the terminal with a time interval offset _ long of the power saving signal from the DRX cycle.
Here, the time interval between the power saving signal and the DRX cycle may be an additional information field added in the power saving signal search space set configuration information, or may be a dedicated parameter configuration of the power saving signal in the base station higher layer signaling.
For case 1 above, the process of the terminal receiving the power saving signal may include:
the terminal needs to perform the offset calculation of the monitoring opportunity according to the time interval of the power saving signal from the DRX cycle.
1. If the base station configures two time intervals of offset _ long and offset _ short, the time interval of the power saving signal from the DRX cycle and the start offsets of the short DRX cycle and the long DRX cycle need to satisfy the following relationship, which means that the monitored position of the power saving signal needs to be separated from the first DRX start time in the power saving signal monitoring cycle by a certain time interval, and this time interval is the power saving configured by the base stationTime interval offset of signal from DRX periodlongAnd offsetshort：

3. If only the second monitoring period T2 is configured in the search space set, the terminal only calculates the corresponding monitoring opportunity offset value according to the base station configuration parameters every M (M is an integer and M is greater than or equal to 1) long DRX periods before the long DRX period, specifically as follows:

When the terminal receives the MAC CE carrying the DRX command, starting DRX, then the terminal enters a short DRX period, and starting or restarting a short DRX period timer (DRX-ShortCycleTimer). At this time, the terminal performs power saving signal listening before each short DRX cycle. If the base station configures an offset _ gap, the terminal performs candidate power-saving signaling monitoring according to the calculated offset _ gap power-saving signaling monitoring offset before the active period of the short DRX cycle. And if the base station configures two monitoring time intervals, the terminal monitors candidate power-saving signals according to the power-saving signal monitoring offset calculated by the offset _ short before the short DRX period activation period.
In the short DRX cycle, the terminal monitors the PDCCH only during the active period. The DRX inactivity timer (DRX-inactivity timer) is started or restarted whenever the terminal receives DCI with a new data indication. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer expires, the terminal adopts a short DRX cycle. The terminal performs power saving signal monitoring before each short DRX cycle. If the base station configures an offset _ gap, the terminal performs candidate power-saving signaling monitoring according to the calculated offset _ gap power-saving signaling monitoring offset before the active period of the short DRX cycle. And if the base station configures two monitoring time intervals, the terminal monitors candidate power-saving signals according to the power-saving signal monitoring offset calculated by the offset _ short before the short DRX period activation period.
When a short DRX period timer (DRX-ShortCycleTimer) is overtime or receives a MAC CE carrying a long DRX command sent by a base station, the terminal enters a long DRX period. The terminal performs power saving signal monitoring before each long DRX cycle. If the base station configures an offset _ gap, the terminal performs candidate power-saving signaling monitoring according to the calculated offset _ gap power-saving signaling monitoring offset before the active period of the short DRX cycle. If the base station configures two monitoring time intervals, the terminal performs candidate power-saving signal monitoring according to the power-saving signal monitoring offset calculated by offset _ long before the short DRX period activation period.
When the terminal receives the DCI with the new data indication during the activation of the long DRX cycle, a DRX inactivity timer (DRX-inactivity timer) is turned on or restarted. When the timer times out, the terminal enters a sleep period, i.e., an inactive state, and simultaneously the terminal starts or restarts a short DRX cycle timer (DRX-ShortCycleTimer). Before the timer expires, the terminal is in a short DRX cycle. The terminal performs power saving signal monitoring before each short DRX cycle. If the base station configures an offset _ gap, the terminal performs candidate power-saving signaling monitoring according to the calculated offset _ gap power-saving signaling monitoring offset before the active period of the short DRX cycle. If the base station is configured with two monitoring time intervals, the terminal carries out candidate power-saving signal monitoring according to the power-saving signal monitoring offset calculated by the offset _ short before the short DRX period activation period.
When the terminal is in the short DRX period and a short DRX period timer (DRX-ShortCycleTimer) is not expired, if the MAC CE with the long DRX command sent by the base station is received, the terminal enters the long DRX period. At this time, the terminal performs power saving signal monitoring before each long DRX cycle. If the base station configures an offset _ gap, the terminal performs candidate power-saving signaling monitoring according to the calculated offset _ gap power-saving signaling monitoring offset before the active period of the short DRX cycle. If the base station configures two monitoring time intervals, the terminal performs candidate power-saving signal monitoring according to the power-saving signal monitoring offset calculated by offset _ long before the short DRX period activation period.
Further, the terminal monitors the power saving signal before the active period (on-duration) of the DRX cycle, and performs a subsequent DRX monitoring operation according to the monitored power saving signal. For example, if the terminal receives the power-saving signal at a monitoring opportunity of the power-saving signal, the terminal enters an active state and performs PDCCH monitoring during the subsequent activation of the DRX cycle; otherwise, the terminal continues to be in an inactive state during the subsequent active period of the DRX cycle. The above-mentioned monitoring action of the candidate DRX is only an example, and the embodiment of the present application is not limited to performing other processing operations.
Example nine
Example nine is to configure the power saving signal by the base station in a scenario where the power saving signal is transmitted within a plurality of CORESET, wherein the listening offset of the power saving signal is configured by a time interval from the DRX cycle.
In some cases, for example, in FR2 scenario, the transmit/receive beams change rapidly, and the terminal needs to perform beam scanning to determine a suitable transmit beam or receive beam for the beam where the power saving signal is located, in this case, the power saving signal is transmitted on multiple beams, and different beams may be indicated by the core set where the power saving signal is located, or may be indicated by the associated SSB or CSI-RS. In this embodiment, for example, the beam information is indicated by the CORESET associated with the search space sets, for this case, the base station configures a plurality of search space sets for the terminal, each search space set is associated with one control resource set CORESET, the search space sets may be time division multiplexed, and the beam information carried by the CORESET associated with different search space sets may be the same or different. Taking the R15 standard as an example, a maximum of 3 CORESET are configured on each BWP. For example, assume that the base station configures 3 search space sets for the terminal to listen to the power saving signal, where each search space set is associated with a CORESET, indicating a beam. The monitoring position of the power saving signal can be adjacent 3 × k (k is more than or equal to 1) time slots, in this embodiment, the monitoring position of the power saving signal is configured by the time interval between the power saving signal and the DRX cycle, that is, different power saving signals are configured with different time intervals apart from the DRX cycle:
1. If the base station configures only one time interval for each search space set (or control resource set), which is applicable to both the long DRX cycle and the short DRX cycle, the time intervals corresponding to different search space sets (or control resource sets) are offset _ gap1, offset _ gap2, and offset _ gap3, respectively.
2. If the base station configures only two time intervals for each search space set (or control resource set), corresponding to the long DRX cycle and the short DRX cycle, respectively, the base station needs to additionally configure the following time intervals: offset _ long1, offset _ short1, offset _ long2, offset _ short2, offset _ long3 and offset _ short3 are respectively for different sets of search spaces (or control resource sets).
Here, the time interval between the power saving signal and the DRX cycle may be an information field additionally added to the power saving signal search space set configuration information, or may be parameter configuration of an information field specific to the power saving signal in a base station higher layer signaling.
The terminal needs to perform the offset calculation of the monitoring opportunity according to the time interval between the power saving signal and the DRX cycle, and the specific calculation process is the same as that in example eight, which is not described herein again.
The procedure for monitoring the power saving signal by the subsequent terminal is also the same as that in example eight, and is not described herein again.
Example ten
Example ten provides a way for a base station to configure power saving signals in a scenario where the power saving signals are transmitted within multiple CORESETs, wherein the listening offset of the power saving signals is configured by the listening offset concentrated in the search space.
In some cases, for example, in FR2 scenario, the transmit and receive beams change rapidly, and the terminal needs to perform beam scanning to determine a suitable transmit beam or receive beam for the beam where the power saving signal is located, in this case, the power saving signal is transmitted on multiple beams, and different beams may be indicated by the core set where the power saving signal is located, or may be indicated by the associated SSB or CSI-RS. In this embodiment, for example, the beam information is indicated by the CORESET associated with the search space sets, for this case, the base station configures a plurality of search space sets for the terminal, each search space set is associated with one control resource set CORESET, the search space sets may be time division multiplexed, and the beam information carried by the CORESET associated with different search space sets may be the same or different. Taking the R15 standard as an example, a maximum of 3 CORESET are configured on each BWP. The base station can configure 3 search space sets for the terminal to monitor the power saving signal, and each search space set is associated with one CORESET and indicates one beam. The listening position of the power saving signal may be adjacent 3 × k (k is greater than or equal to 1) time slots, in this embodiment, the listening position of the power saving signal is configured by listening offset in the search space set, that is, different listening offset values are configured in the search space set for different power saving signals:
1. If the base station only configures one listening offset value for each search space set, which is applicable to both the long DRX cycle and the short DRX cycle, the listening offset values in different search space sets are offset _11, offset _12, and offset _13, respectively.
2. If the base station only configures two monitoring offset values for each search space set, which correspond to the long DRX cycle and the short DRX cycle, respectively, the base station needs to additionally configure the following monitoring offset values: offset _11, offset _21, offset _12, offset _22, offset _13, and offset _23 are listening offset values for different sets of search spaces, respectively.
Here, the listening offset value of the power saving signal needs to satisfy a certain difference with the starting time of the DRX cycle, and the specific relationship is the same as the example one, and is not described herein again.
The following procedure of monitoring the power saving signal by the terminal is also the same as the example i, and is not described herein again.
