Description

Energy saving indication and energy saving method, base station, equipment and storage medium

Technical Field

The present invention relates to the field of communications, and in particular, to a method, a base station, a device, and a storage medium for energy saving indication and energy saving.

Background

Recently, the smart phone has more and more powerful functions, and the power consumption of the terminal directly affects the user experience, so that the user has more and more strong demand for saving energy of the terminal.

The basic mechanism of DRX (Discontinuous Reception) is to configure a DRX cycle (DRX cycle) for a UE (user equipment) in an RRC _ CONNECTED state (RRC _ CONNECTED state, radio Resource Control layer). The DRX cycle is composed of "On Duration" and "Opportunity for DRX (possibly into DRX)". In the "On Duration" time, the UE monitors and receives a PDCCH (Physical Downlink Control Channel); during the "Opportunity for DRX" time, the UE does not receive data of the downlink channel to save power consumption.

With the advent of the 5G era, the Power saving requirement of people for a 5G terminal is higher and higher, and in order to reduce Power consumption used by a PDCCH and improve user experience, in the prior art, an energy saving signal is set for a connected UE, that is, a base station uses a DCI-based (Downlink Control Information) energy saving signal (PSS) to indicate whether a UE configured with DRX needs to wake up to monitor the PDCCH during a DRX on duration.

The base station can predict whether data arrive in the DRX cycle period of the UE according to the service characteristics of the UE so as to indicate whether the UE needs to wake up, and the base station can indicate a plurality of UEs to monitor the same DCI-based PSS at the same time. However, considering the uncertainty of the actual data arrival time of different UEs, even if UEs in the same group all have data scheduling during a certain DRX cycle, sometimes the base station cannot guarantee that UEs that instruct to wake up can be scheduled at the first PDCCH monitoring occasion at the beginning of the DRX on duration, and if data arrives at a certain time during the DRX on duration for some UEs, the base station cannot send PDCCH instruction scheduling data at the first PDCCH monitoring occasion at the beginning of the DRX on duration; if the next DRX cycle schedule is cached, data transmission delays may be affected.

Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

Example 1

The embodiment provides an energy saving indication method, which is suitable for a base station to indicate to user equipment so that the user equipment can achieve the purpose of saving power consumption. The method comprises the step of issuing an indication. The indication information includes corresponding monitoring information of at least one UE which needs to wake up in a first DRX period in the future, and the monitoring information is used for indicating the corresponding UE to monitor the PDCCH at a specified PDCCH monitoring opportunity after a DRX on duration timer starts.

One base station corresponds to a plurality of user equipment, and the base station can predict whether data arrives at each user equipment in the DRX period according to the service characteristics of different user equipment, so as to determine whether the user equipment needs to wake up in the first DRX period in the future. For the above estimation of the specific principles and processes, reference is made to the prior art and no specific description is made here. One user equipment corresponds to one monitoring message, and the indication message can indicate one or more user equipments simultaneously so as to reduce signaling overhead.

The specified PDCCH monitoring occasion may be the first PDCCH monitoring occasion after the DRX on duration timer starts, or may be a non-first PDCCH monitoring occasion after the DRX on duration timer starts. Monitoring the PDCCH from a designated PDCCH monitoring occasion after the DRX on duration timer starts, which may be understood as skipping (skip) a designated number of PDCCH monitoring occasions after the DRX on duration timer starts, and monitoring the PDCCH from a PDCCH monitoring occasion that is subsequent to the skipped last PDCCH monitoring occasion, wherein the PDCCH monitoring occasion that is subsequent to the skipped last PDCCH monitoring occasion is the designated PDCCH monitoring occasion. For example, if the ue is instructed to skip 2 PDCCH monitoring occasions after the DRX on duration timer starts, the ue starts monitoring from the 3 rd PDCCH monitoring occasion. In the method, the monitoring information corresponding to one ue specifically uses which PDCCH monitoring time after the DRX on duration timer starts as the designated PDCCH monitoring time, and may be determined according to the time when the data arrives during the DRX on duration of the ue.

In this embodiment, the indication information is preferably carried by a Power Saving Signal (PSS). That is, the indication information is added to the PPS, as for the information originally contained in the PSS, such as the wake-up indication and the secondary cell dormancy indication (SCell dormant indication) for the user equipment configured with Carrier Aggregation (CA) can be still retained, which is not modified by the embodiment. Of course, the possibility that other signals sent to the user equipment by the base station carry the indication information is not excluded.

If the indication information is carried by the energy-saving signal, the monitoring information corresponding to each user equipment may occupy a plurality of bits in the energy-saving signal respectively.

Preferably, for the ue configured with carrier aggregation, the corresponding monitoring information occupies several bits behind the secondary cell dormant indication of the ue in the energy-saving signal. The bits following the secondary cell dormancy indication may be bits immediately following the secondary cell dormancy indication, or may not be bits immediately following the secondary cell dormancy indication, that is, other information may or may not be inserted between the secondary cell dormancy indication and the monitored information.

In this embodiment, the number of bits of the energy saving signal occupied by the monitoring information corresponding to each ue may be the same or different, and the number of bits occupied by the monitoring information may specifically be

And the number of the PDCCH monitoring occasions which can be skipped by the user equipment corresponding to the monitoring information is configured for the user equipment by the base station after the user equipment enters the RCC connection state. Correspondingly, the method also comprises the steps of configuring at least one type of PDCCH monitoring opportunity number which can be skipped by the user equipment after the user equipment enters the RRC connection state, and determining the corresponding X1 value according to the configured type of PDCCH monitoring opportunity number which can be skipped by the user equipment.

For example, one user equipment can skip the PDCCH monitoring occasions with the number of 2 through configuration, X1 is 1, and the corresponding monitoring information occupies 1bit;

and the other user equipment can skip 2, 4 and 6 PDCCH monitoring occasions through configuration, then X1 takes 3, and the corresponding monitoring information occupies 2bits.

Since one ue is configured to skip every PDCCH monitoring occasion in the entire DRX on duration at most, X1 does not exceed the total number of DRX on duration monitoring occasions. For example, the DRX on duration includes 8 PDCCH monitoring occasions in total, and the maximum number of PDCCH monitoring occasions that the ue can skip is configurable to 8 cases, which are 1, 2, 3, … …, and 8, respectively, so X1 cannot exceed 8.

When the number of the monitoring occasions of the skipped PDCCHs corresponding to the UE is configured, all the skipped numbers can be regarded as a list (list), the position sequence of all the skipped numbers in the list is known, and the corresponding skipped numbers can be determined by appointing one position in the list. In view of the above, the present embodiment further maps the allocated location sequence of the number of PDCCH monitoring occasions that the ue can skip to the code point value indicated by the corresponding bit in the energy saving signal.

And when the appointed monitoring time is the non-first PDCCH monitoring time after the DRX on duration timer is started, setting the bit position occupied by the monitoring information as a code point value corresponding to the number of the PDCCH monitoring time needing to be skipped when the PDCCH monitoring time before the appointed PDCCH monitoring time is skipped. The user equipment can determine the number of corresponding PDCCH monitoring occasions needing to be skipped through the code point value, so that the PDCCH monitoring occasions with the corresponding number are skipped, and monitoring is started from the next PDCCH monitoring occasion.

And when the appointed monitoring time is the first PDCCH monitoring time after the starting of the DRX on duration timer, setting the bit occupied by the monitoring information as a specific code point value. The particular codepoint value may be all 0's or all 1's, or other values that are pre-configured. The UE determines that PDCCH monitoring needs to be started at the first PDCCH monitoring opportunity after the DRX on duration timer is started through the specific code point value.

An optimization process of the method is given below, and may specifically include the following steps, as shown in fig. 1:

step S11: after user equipment enters an RRC connection state, configuring at least one skipped PDCCH monitoring opportunity number for the user equipment;

step S12: determining a corresponding X1 value according to the number of the configured monitoring occasions of the skippable PDCCH;

step S13: determining whether the UE needs to wake up in a first DRX period in the future and the number of PDCCH monitoring occasions needing to be skipped after the UE wakes up according to the data arrival time of the UE in a DRX on duration period, wherein if the UE is required to start monitoring from a non-first PDCCH monitoring occasion after a DRX on duration timer, more than one PDCCH monitoring occasion needs to be skipped, and if the UE is required to start monitoring from a first PDCCH monitoring occasion after the DRX on duration timer, 0 PDCCH monitoring occasion needs to be skipped;

step S14: sending an energy-saving signal, wherein a plurality of bits of the energy-saving signal behind a secondary cell dormancy indication of the UE are set as code point values corresponding to the number of the PDCCH monitoring occasions needing to be skipped, and the number of the bits is

A bit.

With the method of this embodiment, the base station can specify, through the indication information (or the energy saving signal including the indication information), from which PDCCH monitoring occasion different ues start monitoring after the DRX on duration timer starts.

The following describes the components of the power saving signal carrying the indication signal in detail with reference to two examples:

example 1, each UE has only one configuration capable of skipping the number of PDCCH monitoring occasions, and PSS passes through

And indicating whether the corresponding UE skips the configured PDCCH monitoring time number and then starts monitoring or starts monitoring from the first PDCCH monitoring time after the starting of the DRX on duration timer:

the base station configures energy-saving configuration information of a plurality of connected UEs as follows:

UE0: configuring a PS-RNTI (Radio Network temporary Identity ) value, wherein UE0 information indicates that the initial bit position of the PSS DCI is 0, and the number of SCell groups configured with CA is 3;

UE1: configuring the same PS-RNTI value, wherein the UE1 information indicates that the initial bit position of the PSS DCI is 6, and the group number of the SCells configured with the CA is 5;

and the UE2: configuring the same PS-RNTI value, wherein the UE2 information indicates that the initial bit position of the PSS DCI is 14, and the group number of the SCells configured with the CA is 3;

and the UE3: configuring the same PS-RNTI value, wherein the UE3 information indicates that the initial bit position of the PSS DCI is 20;

as shown in fig. 2, UE0-UE3 can be regarded as a group of UEs using the same energy saving signal, the traffic characteristics of the UEs are the same or similar, and the parameters such as DRX cycle configured by the base station, slot offset (offset slot) and the like are the same; the PSS parameters comprise that the bit length of the PSS DCI is 23bits, the search space monitored by the PSS and the parameters such as CORESET are the same, and UE0-UE3 monitor the PSS according to PSS parameter configuration instructions before each DRX cycle begins.

The base station indicates the number N of the skipped PDCCH monitoring occasions of each UE through the energy-saving signal PSS according to the actual service characteristics and DRX configuration of each UE as follows:

UE0：N＝4；

UE1：N＝2；

UE2：N＝4；

UE3：N＝6；

in the PSS, 1bit is adopted to indicate whether monitoring is started after the DRX on duration timer is started and after the configured number of PDCCH monitoring occasions is skipped (the code point value of the bit is correspondingly set to be 1) or monitoring is started from the first PDCCH monitoring occasion (the code point value of the bit is correspondingly set to be 0), and the bit position is immediately behind the SCell downlink indication.

Assume that the current data arrival situation of each UE is as follows:

UE0 starts data scheduling at the beginning of DRX on duration, the SCell activated in the SCell group0 is in a non-dormant state, UE0 needs to monitor a PDCCH on the SCell activated in the SCell group0 and receive data scheduling, and an SCell group1 and an SCell group2 are in dormant states;

UE1 has no data scheduling at the beginning of the DRX on duration, but data arrives during the DRX on duration, and the base station indicates that each SCell group of UE1 is in a dormant state through the PSS;

the UE2 does not have data scheduling in the next DRX period, the UE2 does not need to wake up, and meanwhile, the base station indicates that all SCell groups of the UE2 are in a dormant state through the PSS;

UE3 has data scheduling at the beginning of DRX on duration, and UE3 needs to wake up to monitor PDCCH.

Then: as shown in fig. 3, the PSS DCI transmitted by the base station should be 110000 10000010 000000100, and the meaning of the corresponding bit is as follows, UE0 and UE3 do not need to skip the PDCCH monitoring occasion, and monitor the PDCCH on the indicated cell from the first PDCCH monitoring occasion after the DRX on duration starts, so the corresponding bit is set to 0; UE2 has no data and does not need to wake up; UE1 has data scheduling during the DRX on duration, and UE1 needs to wake up, but does not need to start monitoring at the first PDCCH monitoring occasion after the DRX on duration starts, and needs to skip 2 PDCCH monitoring occasions after the DRX on duration starts to start monitoring, so the corresponding bit is set to 1. The monitoring state after UE1 receives PSS is shown in fig. 4, where the DRX on duration period in the figure has 6 PDCCH monitoring occasions, 2 monitoring occasions drawn by the dotted line are the monitoring occasions that need to be skipped over, and 4 monitoring occasions drawn by the solid line are the monitoring occasions that need to be monitored.

Example 2, each UE has a plurality of configurations capable of skipping the number of PDCCH monitoring occasions, and the PSS indicates, through the Xbit, whether the corresponding UE starts monitoring after skipping a certain configured number of PDCCH monitoring occasions after the DRX on duration timer starts, or starts monitoring from the first PDCCH monitoring occasion:

the base station configures energy-saving configuration information of a plurality of connected UEs as follows, which is the same as the example 1:

UE0: configuring a PS-RNTI value, wherein UE0 information indicates that the initial bit position of the PSS DCI is 0, and the number of SCell groups configured with CA is 3;

as shown in fig. 5, UE0-UE3 can be regarded as a group of UEs using the same energy saving signal, the traffic characteristics of the UEs are the same or similar, and the parameters such as DRX cycle configured by the base station and slot offset are the same; the PSS parameters comprise that the bit length of the PSS DCI is 23bits, the search space monitored by the PSS and the parameters such as CORESET are the same, and UE0-UE3 monitor the PSS according to PSS parameter configuration instructions before each DRX cycle begins.

The base station can configure the following quantity of PDCCH monitoring occasions skipped by each UE according to the actual service characteristics and DRX configuration of each UE, wherein each UE in the PSS adopts X =2bits to indicate whether to start monitoring after a certain number of PDCCH monitoring occasions are skipped after a DRX on duration timer is started or to start monitoring from the first PDCCH monitoring occasion, if CA is configured, the corresponding 2bit position is immediately behind the SCell management indication:

UE0 X1＝3：

the number of 1 st skipping PDCCH monitoring occasions N1=2, and the code point value corresponding to 2bits is 01;

the number of the skipping PDCCH monitoring occasions of the 2 nd type N2=4, and the code point value corresponding to 2bits is 10;

the number of the 3 rd skipping PDCCH monitoring occasions N3=6, and the code point value corresponding to 2bits is 11;

UE1 X1＝3：

the number of 1 st skipping PDCCH monitoring occasions N1=1, and the code point value corresponding to 2bits is 01;

the number of the 2 nd skipping PDCCH monitoring occasions N2=2, and the code point value corresponding to 2bits is 10;

the number of the 3 rd skipping PDCCH monitoring occasions N3=4, and the code point value corresponding to 2bits is 11;

UE2 X1＝3：

the number of the skipping PDCCH monitoring occasions N2=3 in the 2 nd category, and the code point value corresponding to 2bits is 10;

the number of the 3 rd skipping PDCCH monitoring occasions N3=5, and the code point value corresponding to 2bits is 11;

UE3 X1＝2：

the number of the 1 st skipping PDCCH monitoring occasions N1=2, and the code point value corresponding to 2bits is 01;

and UE0-UE3, if monitoring is started from the first PDCCH monitoring opportunity without skipping any number of monitoring opportunities, setting the code point value corresponding to 2bits to 00.

Assuming that the current data arrival situation of each UE is as follows,

the data arrival conditions of UE0, UE2 and UE3 are the same as example 1, UE1 has no data scheduling at the beginning of DRX on duration, but there is data arrival during DRX on duration, UE1 needs to skip 4 PDCCH monitoring occasions to start monitoring the PDCCH, and the base station indicates that each SCell group of UE1 is in the downlink state through the PSS.

Then: as shown in fig. 6, the indication meaning that the PSS DCI transmitted by the base station should be 110000 10000011 000000, ue0, ue2, ue3 is the same as example 1. The meaning of bit corresponding to UE1 is as follows, UE1 has data scheduling only during DRX on duration, UE1 needs to wake up, but does not need to start monitoring from the first PDCCH monitoring occasion after DRX on duration starts, but needs to skip the 3 rd configured skipped PDCCH monitoring occasion indicated by bit 11 in PSS DCI, that is, UE1 needs to skip 4 PDCCH monitoring occasions to start monitoring.

The monitoring state after UE1 receives PSS is shown in fig. 7, where the DRX on duration period includes 6 PDCCH monitoring occasions, where 4 monitoring occasions drawn by the dotted line are monitoring occasions that need to be skipped over, and 2 monitoring occasions drawn by the solid line are monitoring occasions that need to be monitored.

Example 2

The embodiment provides an energy saving method for user equipment, which is suitable for the user equipment to achieve the purpose of saving power consumption. The method comprises the step of receiving indication information. The indication information includes monitoring information corresponding to at least one ue that needs to wake up in a first DRX cycle in the future, where the monitoring information is used to indicate that the corresponding ue monitors the PDCCH at a specific PDCCH monitoring time after a DRX on duration timer starts.

The indication information is the same as the indication information issued in the method of embodiment 1, and for the specific description of the indication information, reference may be made to embodiment 1.

In this embodiment, if the indication information is carried in the energy saving signal, then: the method includes the step of receiving the power save signal.

In this embodiment, the method may further include the step of receiving X1 configurations skipping different PDCCH monitoring opportunity numbers after the ue enters the RRC connected state.

In this embodiment, if the configured position sequence of the number of PDCCH monitoring occasions that the ue can skip is mapped to the code point value indicated by the corresponding bit in the energy-saving signal, and when the designated monitoring occasion is a non-first PDCCH monitoring occasion after the DRX on duration timer starts, the bit occupied by the monitoring information is set to the code point value corresponding to the number of PDCCH monitoring occasions that need to skip when the PDCCH monitoring occasion is previous to the designated PDCCH monitoring occasion, then:

the method also comprises a step of determining the number of PDCCH monitoring occasions which need to be skipped by the user equipment after the starting of the DRX duration timer according to a code point value set on a bit occupied by the monitoring information.

In this embodiment, if the bit occupied by the monitoring information is set to a specific code point value, then:

the method further includes the step of monitoring the PDCCH from a first PDCCH monitoring occasion after the DRX on duration timer starts.

With the method of this embodiment, the ue may determine, through the indication information (or the energy saving signal including the indication information), from which PDCCH monitoring occasion to start monitoring after the DRX on duration timer starts.

Example 3

The present embodiment provides a base station, as shown in fig. 8, including: the indication issuing module 101.

The indication sending module 101 is configured to send indication information, where the indication information includes monitoring information corresponding to at least one ue that needs to wake up in a first DRX cycle in the future, and the monitoring information is used to indicate the corresponding ue to monitor the PDCCH at a specified PDCCH monitoring time after a DRX on duration timer starts.

The specified PDCCH monitoring occasion may be the first PDCCH monitoring occasion after the DRX on duration timer starts, or may be a non-first PDCCH monitoring occasion after the DRX on duration timer starts. Monitoring the PDCCH from a designated PDCCH monitoring occasion after the DRX on duration timer starts, which may be understood as skipping (skip) a designated number of PDCCH monitoring occasions after the DRX on duration timer starts, and monitoring the PDCCH from a PDCCH monitoring occasion that is subsequent to the skipped last PDCCH monitoring occasion, wherein the PDCCH monitoring occasion that is subsequent to the skipped last PDCCH monitoring occasion is the designated PDCCH monitoring occasion. The indication sending module 101 may further be configured to determine, according to a time at which data arrives during the DRX on duration of the ue, which PDCCH monitoring occasion that is after the DRX on duration timer is started by the monitoring information corresponding to the ue is the designated PDCCH monitoring occasion.

In this embodiment, the indication information is preferably carried by a Power Saving Signal (PSS). That is, the indication information is added to the PPS, and information originally contained in the PSS, such as an awake indication and a secondary cell dormancy indication (SCell dormant indication) for a user equipment configured with Carrier Aggregation (CA), may be retained, which is not modified in the present embodiment. Of course, the possibility that other signals sent to the user equipment by the base station carry the indication information is not excluded.

If the indication information is carried by the energy-saving signal, the monitoring information corresponding to each ue may occupy a plurality of bits in the energy-saving signal.

Preferably, for the ue configured with carrier aggregation, the corresponding monitoring information occupies several bits behind the secondary cell dormant indication of the ue in the energy saving signal. The bits following the secondary cell dormancy indication may be bits immediately following the secondary cell dormancy indication, or may not be bits immediately following the secondary cell dormancy indication, that is, other information may or may not be inserted between the secondary cell dormancy indication and the monitored information.

The base station may further include: the configuration module 102 is listened to. The monitoring configuration module 102 is configured to configure at least one of the numbers of PDCCH monitoring occasions that the user equipment can skip after entering the RRC connected state, and determine a corresponding X1 value according to the number of PDCCH monitoring occasions that the user equipment can skip. Wherein, X1 does not exceed the total number of the DRX on duration monitoring occasions.

And when the appointed monitoring time is the non-first PDCCH monitoring time after the DRX on duration timer starts, setting the bit position occupied by the monitoring information as a code point value corresponding to the number of the PDCCH monitoring time needing to be skipped when the PDCCH monitoring time before the appointed PDCCH monitoring time is skipped. The user equipment can determine the number of corresponding PDCCH monitoring occasions needing to be skipped through the code point value, so that the PDCCH monitoring occasions with the corresponding number are skipped, and monitoring is started from the next PDCCH monitoring occasion.

And when the appointed monitoring time is the first PDCCH monitoring time after the starting of the DRX on duration timer, setting the bit position occupied by the monitoring information as a specific code point value. The particular codepoint value may be all 0's or all 1's, or other values that are pre-configured. The UE determines that PDCCH monitoring needs to be started at the first PDCCH monitoring opportunity after the DRX on duration timer is started through the specific code point value.

The base station of this embodiment may specify, through the indication information (or the energy saving signal including the indication information), from which PDCCH monitoring occasion different ues start monitoring after the DRX on duration timer starts.
