Description

Discontinuous reception processing method, terminal, device and medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a discontinuous reception processing method, a terminal, an apparatus, and a medium.

Background

In the conventional cellular network communication, uplink/downlink data and control information are transmitted between a terminal and a network side device through a Uu interface. A brief description of the DRX (Discontinuous Reception) mechanism of the cellular communication system is provided below.

In a mobile communication system based on a shared channel, for example, in LTE (Long Term Evolution), transmission of uplink and downlink data is controlled by a base station (eNB) scheduler, and when the scheduler determines to schedule a user, the terminal is notified via a control channel on what resource to transmit or receive data. A terminal, for example, a User Equipment (UE), monitors a control channel, and when it is detected that scheduling information of the terminal includes its own scheduling information, the terminal completes transmission (uplink) or reception (downlink) of data according to an instruction on the control channel. In the active state, since the terminal does not determine when the eNB schedules it, a common working mode is that the terminal continuously monitors the control channel and parses each subframe containing its downlink scheduling control channel to determine whether it is scheduled. The working mode can obtain higher efficiency under the condition that the terminal has larger data volume and is likely to be frequently scheduled. However, for some services, the frequency of arrival of data is low, resulting in a small number of times that the terminal is scheduled, which would undoubtedly increase its power consumption if the terminal still continuously listens to the control channel. In order to solve the problem of power consumption, the cellular network communication system adopts a DRX operation mode, in which the terminal periodically monitors the control channel, thereby achieving the purpose of power saving.

The prior art has the defect that when the terminal carries out communication of the direct communication interface, the power saving of the direct communication interface cannot be realized.

Detailed Description

The inventor notices in the process of invention that:

fig. 1 is a schematic diagram of a cellular communication network, as shown in the figure, in a conventional cellular network communication, uplink/downlink data and control information are transmitted between a terminal and a network side device through a Uu interface.

The DRX rationale for a cellular communication system is briefly explained as follows:

fig. 2 is a schematic diagram of a DRX procedure, and the basic principle of DRX is shown in fig. 2. Wherein, the On duration represents the time period for the UE to monitor the control channel, during which the radio frequency channel is opened and the control channel is monitored continuously; at other times except for the On duration, the UE is in Sleep state, and its radio link is closed and no longer monitors the control channel, so as to achieve the purpose of saving power. The On Duration is a periodic occurrence (Cycle), and the specific period is realized by the eNB configuration.

The DRX mechanism of cellular networks takes into account the arrival model of data traffic, i.e. the arrival of data packets is bursty (it is understood that once a data packet arrives, more packets arrive consecutively in a shorter time). In order to adapt to the service arrival characteristics, the LTE DRX process employs multiple timers and is combined with a Hybrid Automatic Repeat reQuest (HARQ) process to achieve better power saving performance.

The DRX related timer is briefly explained as follows.

DRX-onDurationTimer (DRX on duration timer): the time the UE wakes up periodically to listen to the control channel, as shown in fig. 2.

Short DRX cycle Timer (DRX Short cycle Timer): for better matching with the data service arrival characteristics, the cellular network communication system supports the configuration of two DRX cycles: long cycle and short cycle. The on duration timers for the two cycles are the same, but the sleep time is different. In the short cycle, the sleep time is relatively shorter and the UE can listen to the control channel again faster. Long cycle is mandatory to configure and is the initial state of the DRX procedure; the short cycle is optional. The short DRX cycle timer sets the time for which the short cycle duration is to be used. After the Short cycle timer times out, the UE will use the Long cycle.

DRX-inactivity timer (DRX inactivity timer): after configuring DRX, when the UE receives the control signaling for HARQ initial transmission in Active Time (Active period) within a Time allowed to monitor the control channel, the UE starts the timer, and before the timer expires, the UE continuously monitors the control channel. If the UE receives the control signaling of the HARQ initial transmission before the drx-inactivity timer is overtime, the drx-inactivity timer is terminated and restarted.

HARQ RTT Timer (HARQ Round Trip delay Timer; RTT: Round Trip delay, Round Trip Time): the method is divided into drx-HARQ-RTT-TimeDL (HARQ round trip delay timer downlink) and drx-HARQ-RTT-TimeUL (HARQ round trip delay timer uplink), and aims to ensure that the UE does not monitor a control channel before next retransmission, so as to achieve better power saving effect. In the following behavior example, the first symbol after PUCCH (Physical Uplink Control Channel) transmission of UE-related process is started, and the timer is turned on. If the decoding of the data in the corresponding HARQ process was unsuccessful after the previous HARQ transmission (UE feeds back NACK), the UE opens drx-retransmission timerdl after DL HARQ RTT Timer times out. If the data in the corresponding HARQ process is decoded successfully (the UE feeds back ACK) after the previous HARQ transmission, the UE does not start drx-retransmission TimerDL after the drx-HARQ-RTT-TimerDL timer is overtime. If only drx-HARQ-RTT-TimerDL is currently running, the UE does not monitor the control channel.

HARQ retransmission Timer (HARQ retransmission Timer): and is classified as DRX-retransmission timerdl (downlink DRX retransmission timer) or DRX-retransmission timerrul (uplink DRX retransmission timer). In the following example, during the running of the DL HARQ retransmission Timer, the UE monitors the control signaling and waits for the retransmission scheduling of the corresponding HARQ process.

Active time under DRX is defined as follows:

it can be seen from the above process that any one of the On duration Timer, HARQ transmission Timer, and Inactivity Timer is running, and the UE will monitor the control channel. The Time that the UE listens to the control channel is also called Active Time. In addition to the influence of DRX timer, Active Time in an LTE system also has other factors, and the Active Time of LTE Rel-8 UE comprises the following Time:

time of run of drx-onDurationTimer or drx-InactivetyTimer or drx-RecransmissionTimerDL or drx-RecransmissionTimeUL or ra-ContentionResolutionTimer;

after the UE sends an uplink SR (Scheduling Request), waiting for a time for the base station to send a PDCCH (Physical Downlink Control Channel);

the non-contention Random Access UE receives an RAR (Random Access Response) and then waits for the time of a PDCCH (Cell-Radio Network Temporary Identifier) scheduled by a C-RNTI (Cell-Radio Network Temporary Identifier).

Next, Common DRX (Common DRX) downlink duration calculation will be described.

For short DRX cycles, the duration calculation formula is as follows:

[(SFN*10)+subframe number]modulo(shortDRX-Cycle)＝(drxStartOffset)

modulo(shortDRX-Cycle)；

for the long DRX cycle, the onduration calculation formula is as follows:

[(SFN*10)+subframe number]modulo(longDRX-Cycle)＝drxStartOffset:

wherein:

SFN (System Frame Number): numbering SFN of the current wireless frame;

subframe number: the number of the current subframe;

short DRX-Cycle: a short DRX cycle;

longDRX-Cycle: a long DRX period;

drxStartOffset: RRC (Radio Resource Control) signaling an offset value.

Next, the direct communication will be described.

Direct communication refers to a manner in which a nearby terminal can perform data transmission over a direct communication link (also referred to as Sidelink) within a short range. The wireless interface to which the Sidelink link corresponds is referred to as a direct communication interface, also referred to as a Sidelink interface. Fig. 3 is a schematic diagram of the Sidelink discovery/communication, which is specifically shown in fig. 3.

At present, the DRX of a wireless communication system is only suitable for a Uu interface between a terminal and a network, and a direct communication interface has no DRX mechanism, which means that the direct communication interface can not save electricity. For a direct communication interface, any electricity saving mechanism is not supported at present, so that the power consumption of the terminal is faster and the user experience is not good. Therefore, a power saving mechanism needs to be introduced into the direct communication interface, and one possible way is to introduce a DRX mechanism into the direct communication interface, but at present, there is no solution disclosed how to implement DRX in the direct communication interface.

That is, the disadvantage of the prior art is that the terminal is always kept in the active state when the terminal performs the direct communication interface communication, and the power saving of the direct communication interface cannot be realized.

Based on this, the invention provides a usage scheme of a direct communication interface DRX configuration. By the method, the available DRX configuration of the direct communication interface can be selected more flexibly, and better electricity can be saved.

The following describes embodiments of the present invention with reference to the drawings.

In the description, the implementation of the opposite side from the direct communication terminal and the direct communication terminal, respectively, will be described, and then an example of the implementation of the two in cooperation will be given to better understand the implementation of the scheme given in the embodiment of the present invention. Such an explanation does not mean that the two terminals must be implemented in cooperation or separately, and actually, when the direct communication terminal and the direct communication counterpart of the direct communication terminal are implemented separately, they each solve the problem on their own side, and when the two terminals are used in combination, a better technical effect is obtained.

Fig. 4 is a schematic flowchart of an implementation process of a DRX processing method at a terminal side for sending DRX configuration, as shown in the figure, including:

step 401, configuring multiple sets of DRX configuration to a direct communication opposite terminal of a direct communication terminal by the direct communication terminal through a direct communication interface;

step 402, the direct communication terminal determines the DRX configuration to be used by the direct communication interface;

step 403, the direct communication terminal indicates, to the correspondent node of the direct communication, a DRX configuration to be used by the direct communication interface through the control information corresponding to the direct communication interface.

Fig. 5 is a schematic flow chart of an implementation of a DRX processing method at a terminal side receiving DRX configuration, as shown in the figure, including:

step 501, the direct communication terminal receives a plurality of sets of DRX configurations configured by a direct communication opposite terminal of the direct communication terminal through a direct communication interface;

step 502, the direct communication terminal selects a DRX configuration to be used by the direct communication interface among multiple sets of DRX configurations according to an instruction sent by a direct communication peer of the direct communication terminal through control information corresponding to the direct communication interface.

Specifically, in the scheme, the direct communication terminal configures a plurality of sets of DRX configurations to a direct communication peer of the direct communication terminal through a direct communication interface, and the direct communication terminal determines which set of DRX configurations is specifically used at the direct communication interface and indicates the direct communication peer of the direct communication terminal through control information corresponding to the direct communication interface.

Correspondingly, there are multiple sets of DRX configurations configured by the direct communication peer of the direct communication terminal through the direct communication interface at the direct communication peer, including:

the direct communication terminal determines the DRX configuration to be used by the direct communication interface according to the indication information of the network side equipment serving for the direct communication terminal; and/or the presence of a gas in the gas,

The technical meaning of the term "implementing" used in the embodiments of the present invention may adopt the technical meaning in the industry, for example, refer to the technical meaning of the term UE implementation used in the 3GPP standard.

Two modes will be described below.

In the first mode, the direct communication terminal determines the DRX configuration to be used by the direct communication interface according to the indication information of the network side equipment serving for the direct communication terminal.

In this way, the network side device serving the direct communication terminal sends the indication information to the direct communication terminal, where the indication information is used to indicate the DRX configuration used by the direct communication terminal on the direct communication interface, and the scheme is applicable to a terminal with a Uu interface in an RRC connected state.

Specifically, the indication information sent by the network side device may include the following contents:

direct communication interface identification information, e.g., source or destination address combinations;

direct communication interface DRX configuration indication information, e.g., a direct communication interface DRX configuration number.

Optionally, the indication information may also carry direct communication interface transmission type indication information, where the specific transmission type is broadcast, unicast, or multicast; alternatively, the direct communication interface transmission type is unicast or multicast, etc.

Specifically, the indication information sent by the network side device may be a MAC CE (Media Access Control unit; MAC: Media Access Control; CE: Control unit, Control Element) or PHY (Physical Layer) signaling of the Uu interface. If MAC CE is adopted, the MAC CE needs to use a special LCID (Logical Channel ID) at the Uu port.

Specifically, if the direct communication terminal has a plurality of direct communication interfaces, the DRX configuration information of the plurality of direct communication interfaces may be indicated using separate indication information, or may be multiplexed into one indication information.

a direct communication interface DRX configuration suggestion fed back by the direct communication terminal; or the like, or a combination thereof,

Specifically, in order to assist the network side device of the direct communication terminal to determine which set of DRX configuration the direct communication interface specifically uses, the direct communication terminal may report auxiliary information to the network side device serving the direct communication terminal, where the specific auxiliary information may be:

a direct communication terminal sending end and/or a direct communication opposite end of the direct communication terminal has SLRB (direct communication interface Radio Bearer) indicating information of a data transmission requirement at present;

a direct communication interface DRX configuration suggestion fed back by the direct communication terminal;

And secondly, the direct communication terminal determines the DRX configuration to be used by the direct communication interface according to the implementation of the direct communication terminal.

In this way, the specific DRX configuration to be used at the direct communication interface is determined according to the implementation of the direct communication terminal.

the direct communication opposite end of the direct communication terminal currently has SLRB (synchronization Link Block) indication information required by data transmission; and/or the presence of a gas in the atmosphere,

and the direct communication opposite end of the direct communication terminal proposes a direct communication interface DRX configuration proposal.

Correspondingly, on the side of the direct communication opposite end of the direct communication terminal, the method may further include:

the direct communication terminal reports SLRB indication information with the current data transmission requirement to a direct communication opposite end of the direct communication terminal; and/or reporting a direct communication interface DRX configuration suggestion suggested by a direct communication opposite end of the direct communication terminal.

Specifically, in order to assist the direct communication terminal to determine which set of DRX configurations the direct communication interface specifically uses, the direct communication peer of the direct communication terminal may suggest a DRX configuration of the direct communication interface to the direct communication terminal:

the direct communication opposite end of the direct communication terminal currently has SLRB (synchronization Link Block) indication information required by data transmission;

and the direct communication interface DRX configuration proposal fed back by the direct communication opposite end of the direct communication terminal.

Next, description will be made of an implementation of control information in a direct communication peer in which a direct communication terminal notifies a direct communication terminal of control information corresponding to a direct communication interface.

In a specific implementation, the direct communication interface DRX configuration indication information is a DRX configuration number.

The transmission type of the direct communication interface is broadcast, unicast or multicast; alternatively, the direct communication interface transmission type is unicast or multicast.

Specifically, the control information at least needs to include the following contents: direct communication interface DRX configuration indication information, such as a DRX configuration number.

In implementation, when the direct communication terminal indicates the DRX configuration to be used by the direct communication interface to a direct communication peer of the direct communication terminal through control information corresponding to the direct communication interface, the control information is repeatedly transmitted in one or a combination of the following manners:

the transmission is repeated on a particular time or frequency domain resource.

In a specific implementation, the preset period T is determined according to a pre-configuration or protocol convention, a DRX period, or a direct communication transmission notification.

In a specific implementation, the specific time domain or frequency domain resource is determined according to a pre-configuration or a protocol agreement, or according to a notification of the direct communication terminal.

Correspondingly, the control information is repeatedly received at the opposite side of the direct communication terminal according to one of the following modes or the combination of the following modes:

the reception is repeated on a specific time or frequency domain resource.

Specifically, based on multicast and broadcast in the transmission type, the control information may be sent repeatedly, and a specific rule of repeated transmission may be one of the following:

directly and repeatedly sending the data according to N times of continuous sending;

repeating transmission according to a certain period T; the value of the period T can be pre-configured or agreed by a protocol, and the period T can also take the period of DRX;

repeating the transmission on the particular time/frequency domain resource; the specific time/frequency resource may be protocol agreed or pre-configured or notified by the direct communication terminal to a direct communication counterpart of the direct communication terminal.

In an implementation, the control information is transmitted through a MAC CE of the direct communication interface or a PHY signaling of the direct communication interface.

Specifically, the control information may be MAC CE or PHY signaling of the direct communication interface. If a MAC CE is employed, the MAC CE may use a dedicated LCID at the direct communication interface.

The following description is made with reference to examples.

Example 1:

in this example, the direct communication terminal determines the DRX configuration to be used by the direct communication interface according to an indication of a network side device serving the direct communication terminal, which is in an RRC connected state.

Fig. 6 is a schematic flowchart of an implementation of the DRX processing method in embodiment 1, and as shown in the figure, the DRX processing method may include:

step 601: the direct communication terminal sends a plurality of sets of DRX configurations to a direct communication opposite end of the direct communication terminal.

Step 602: and reporting the auxiliary information.

The step is an optional step, and the auxiliary information is used to assist the network side device corresponding to the direct communication terminal to select the DRX configuration for the direct communication interface.

In order to assist a network side device of a direct communication terminal to determine which DRX configuration is specifically used by the direct communication interface, the direct communication terminal may report auxiliary information to the network side device serving the direct communication terminal, where the specific auxiliary information may be:

the direct communication terminal and/or a direct communication opposite end of the direct communication terminal currently have SLRB indication information of data transmission requirements;

a direct communication interface DRX configuration suggestion fed back by a direct communication opposite terminal of the direct communication terminal;

Step 603: and the network side equipment corresponding to the direct communication terminal indicates the DRX configuration used by the direct communication interface to the direct communication terminal.

Specifically, after the network side device corresponding to the direct communication terminal determines the DRX configuration used by the direct communication interface of the direct communication terminal, the network side device serving the direct communication terminal sends indication information to the direct communication terminal, where the indication is used to indicate the DRX configuration used by the direct communication terminal on the direct communication interface (applicable to a terminal with a Uu interface in an RRC connected state).

The indication information sent by the network side equipment at least comprises the following contents:

In specific implementation, the following may be used:

direct communication interface identification information: a source/destination address combination;

direct communication interface DRX configuration indication information: such as a direct communication interface DRX configuration number.

Optionally, the indication information may also carry direct communication interface transmission type indication information, where the specific transmission type is broadcast, unicast, or multicast; alternatively, the direct communication interface transmission type is unicast or multicast.

The indication information of the network side device may be carried by a MAC CE or PHY signaling of the Uu interface. If a MAC CE is used, the MAC CE needs to use a dedicated LCID (Logical Channel ID) at the Uu port.

If the direct communication terminal has a plurality of direct communication interfaces, the network side device may send the indication information individually based on each direct communication interface when sending the indication information, or send the indication information corresponding to the plurality of direct communication interfaces after multiplexing the indication information into one indication information.

Taking a MAC CE as an example, assuming that one direct communication interface supports at most 8 sets of DRX configurations, and both a direct communication source address and a target address are 24 bits, fig. 7 is a schematic structural diagram of a MAC sub-header corresponding to an indication information MAC CE in embodiment 1, and fig. 8 is a schematic structural diagram of an indication information MAC CE format in embodiment 1. Wherein the MAC subheader corresponding to the MAC CE needs to use the dedicated LCID. The specific description of the 8 sets of DRX configurations and the like in the embodiment is only used for teaching the skilled person how to implement the present invention specifically, but it is not meant to be able to use only 8 sets and 24 bits, more or less DRX configurations can be configured in the implementation, the corresponding numbers of bits are used for identification, and the corresponding manner can be determined according to practical needs in the implementation process.

Since it is possible that multicast/broadcast and unicast use the same direct communication source and destination addresses, there is also a need to further distinguish the transmission type in the MAC CE. Such as may be indicated by the R bit in the MAC CE header.

Step 604: the direct communication terminal indicates the DRX configuration used by the direct communication interface to a direct communication counterpart of the direct communication terminal.

Specifically, the control information at least needs to include the following contents: direct communication interface DRX configuration indication information, such as a DRX configuration number. Optionally, the indication information may also carry direct communication interface transmission type indication information, where a specific transmission type is broadcast, unicast, or multicast; alternatively, the direct communication interface transmission type is unicast or multicast.

The control information may be MAC CE or PHY signaling of the direct communication interface. If a MAC CE is employed, the MAC CE requires the use of a dedicated LCID at the direct communication interface.

Taking a MAC CE as an example, assuming that one direct communication interface supports at most 8 sets of DRX configurations, fig. 9 is a schematic diagram of a MAC subheader structure corresponding to the control information MAC CE in embodiment 1, and fig. 10(a) is a schematic diagram of a DRX configuration number directly indicating a use of the direct communication interface in the control information MAC CE in embodiment 1; fig. 10(b) is a schematic diagram of the control information MAC CE in embodiment 1 indicating the DRX configuration used by the direct communication interface in a bitmap manner, specifically, if at most one direct communication interface supports 8 sets of DRX configurations, 1bit in the MAC CE corresponds to one set of DRX configurations, that is, DRXi indicates whether the ith set of DRX configurations is used. If DRxi is set to 1, it indicates that the direct communication interface will use the ith set of DRX configuration. The specific description of the 8 sets of DRX configurations and the like in the embodiment is only used for teaching a person skilled in the art how to implement the present invention specifically, but it is not intended to be limited to only using 8 sets of DRX configurations and 24 bits, and more or fewer DRX configurations may be configured in the implementation, and are identified by using corresponding numbers of bits, and the corresponding manner may be determined according to practical needs in the implementation process.

Since it is possible that multicast/broadcast and unicast use the same direct communication source and destination addresses, there is also a need to further distinguish the transmission type in the MAC CE. Such as using the R bit in the MAC CE header.

For multicast and broadcast, the control information needs to be sent repeatedly, and a specific rule of repeated transmission may be one of the following:

directly and repeatedly sending the data according to N times of continuous transmission;

repeating transmission according to a certain period T;

the value of the period T can be pre-configured or agreed by a protocol.

Wherein, the period T may also take the period of DRX.

When the transmission is repeated on the specific time/frequency domain resource, the specific time/frequency resource may be protocol agreed or pre-configured or notified to the direct communication counterpart of the direct communication terminal by the direct communication terminal.

Step 605: and data transmission is carried out between the direct communication terminal and a direct communication opposite end of the direct communication terminal according to the current DRX configuration of a direct communication interface.

That is, according to the DRX configuration, during the DRX activation period, the direct communication terminal performs data transmission on the direct communication interface, and the direct communication peer of the direct communication terminal performs data reception on the direct communication interface. During the DRX silent period, the direct communication terminal does not transmit data on the direct communication interface, and the direct communication opposite end of the direct communication terminal does not receive data on the direct communication interface.

Example 2:

in this example, the direct communication terminal determines the DRX configuration to be used by the direct communication interface according to the implementation of the direct communication terminal.

Fig. 11 is a schematic flowchart of an implementation of a DRX processing method in embodiment 2, as shown in the figure, the DRX processing method may include:

step 1101: the direct communication terminal sends a plurality of sets of DRX configurations to a direct communication opposite end of the direct communication terminal.

Step 1102: the direct communication terminal indicates the DRX configuration used by the direct communication interface to a direct communication counterpart of the direct communication terminal.

In particular, how the direct communication terminal determines which set of DRX configurations the current direct communication interface uses depends on the implementation of the direct communication terminal. In order to assist a direct communication terminal in determining which set of DRX configurations the direct communication interface specifically uses, a direct communication peer of the direct communication terminal may feed back to the direct communication terminal:

and the direct communication terminal sends a direct communication interface DRX configuration proposal to the direct communication terminal.

Once the direct communication terminal determines the DRX configuration used by the direct communication interface, the direct communication terminal needs to indicate the currently selected DRX configuration to the direct communication counterpart of the direct communication terminal through control information.

The control information at least needs to include the following: direct communication interface DRX configuration indication information, such as a DRX configuration number. Optionally, the indication information may also carry direct communication interface transmission type indication information, where the specific transmission type is broadcast, unicast, or multicast; alternatively, the direct communication interface transmission type is unicast or multicast.

Taking a MAC CE as an example, assuming that one direct communication interface supports at most 8 sets of DRX configurations, fig. 12 is a schematic diagram of a MAC sub-header structure corresponding to the control information MAC CE in embodiment 2, and fig. 13(a) is a schematic diagram of a DRX configuration number directly indicating a use of the direct communication interface in the control information MAC CE in embodiment 2; fig. 13(b) is a schematic diagram of a control information MAC CE indicating DRX configurations used by a direct communication interface in a bitmap manner in embodiment 2, specifically, if a direct communication interface supports at most 8 sets of DRX configurations, 1bit in the MAC CE corresponds to one set of DRX configurations, that is, DRXi indicates whether the ith set of DRX configurations is used. If DRxi is set to 1, it indicates that the direct communication interface will use the ith set of DRX configuration. The specific description of the 8 sets of DRX configurations and the like in the embodiment is only used for teaching a person skilled in the art how to implement the present invention specifically, but it is not intended to be limited to only using 8 sets of DRX configurations and 24 bits, and more or fewer DRX configurations may be configured in the implementation, and are identified by using corresponding numbers of bits, and the corresponding manner may be determined according to practical needs in the implementation process.

carrying out repeated transmission according to a certain period T;

the value of the period T can be pre-configured or agreed by a protocol.

Wherein, the period T may also take the period of DRX.

Step 1103: and data transmission is carried out between the direct communication terminal and a direct communication opposite end of the direct communication terminal according to the current DRX configuration of a direct communication interface.
