Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In the embodiments of the present disclosure, the term "and/or" describes the association relationship of associated objects, and indicates that there can be three kinds of relationships. For example, A and/or B can indicate that A exists alone, A and B exist at the same time, and B exists alone these three situations. The character "/" generally indicates that the associated objects are an "or" relationship.

In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar.

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

Figure 1 is a schematic diagram of a cellular communication network; in traditional cellular network communication, uplink/downlink data and control information are transmitted between a terminal and a network-side device through a Uu interface.

In a shared channel-based mobile communication system, such as Long Term Evolution (LTE), the transmission of uplink and downlink data is controlled by the base station (evolutional Node B, eNB) scheduler. When the scheduler determines When scheduling a user, it will notify the terminal on which resource to send or receive data through the control channel. The terminal (User Equipment, UE) monitors the control channel, and when it detects its own scheduling information, completes the data according to the instructions on the control channel In the active state, since the terminal is not sure when the eNB will schedule it, a common working mode is that the terminal continuously monitors the control channel, and schedules the downlink for each control channel. The subframes of the control channel are all analyzed to determine whether they are scheduled. This working method can achieve higher efficiency when the terminal data volume is large and may be frequently scheduled. However, for some services, the data The arrival frequency is low, resulting in a small number of times the terminal is scheduled. If the terminal continues to monitor the control channel, it will undoubtedly increase its power consumption. In order to solve the problem of power consumption, the cellular network communication system adopts discontinuous reception (Discontinuous Reception, DRX) working mode, in this working mode, the terminal periodically monitors the control channel, thus achieving the purpose of power saving.

The basic principle of DRX is shown in Figure 2. In the DRX cycle (Cycle), the terminal UE shall monitor the PDCCH (UE shall monitor PDCCH). Among them, the duration (On duration) represents the time period during which the UE monitors the control channel, during which the radio frequency channel is turned on, and continuously monitors the control channel; except for other times (such as DRX opportunity (Opportunity for DRX)), the UE is in Sleep In this state, its RF link will be shut down and no longer monitor the control channel to save power. On Duration is a periodic occurrence (Cycle), and the specific period is implemented by the eNB configuration.

The DRX mechanism of the cellular network considers the arrival model of data services, that is, the arrival of data packets is sudden (it can be understood that once a data packet arrives, more packets will arrive continuously in a short period of time). In order to adapt to the arrival characteristics of such services, the DRX process adopts a variety of timers, which are combined with the Hybrid Automatic Repeat Request (HARQ) process to achieve better power saving performance.

The DRX related timers are as follows:

DRX duration timer (drx-on Duration Timer): The time when the UE periodically wakes up to monitor the control channel, as shown in Figure 2.

Short DRX cycle Timer: In order to better match the characteristics of data service arrival, the cellular network communication system supports the configuration of two DRX cycles: long cycle and short cycle. The on duration timer of the two cycles is the same, but the sleep time is different. In the short cycle, the sleep time is relatively shorter, and the UE can monitor the control channel again faster. Long cycle is mandatory and is the initial state of the DRX process; short cycle is optional. The short DRX cycle timer sets the duration of the short cycle. After the Short cycle timer times out, the UE will use the Long cycle.

DRX inactivity timer (drx-Inactivity Timer): After DRX is configured, when the UE receives the control signaling of HARQ initial transmission within the time allowed to monitor the control channel (the time the UE monitors the control channel (Active Time)) Turn on this timer, and until the timer expires, the UE continuously monitors the control channel. If the UE receives the control signaling of HARQ initial transmission before the drx-Inactivity Timer times out, it will terminate and restart the drx-Inactivity Timer.

HARQ round-trip delay (Round-Trip Time, RTT) timer (HARQ RTT Timer): divided into DRX's HARQ downlink round-trip delay timer (drx-HARQ-RTT-Timer DL) and DRX's HARQ uplink round-trip delay timer The purpose is to make it possible for the UE not to monitor the control channel before the next retransmission, so as to achieve better power saving effect. In the following example, the first symbol after the physical uplink control channel (Physical Uplink Control Channel, PUCCH) transmission of the UE-related process is started, and this timer will be turned on. If the data in the corresponding HARQ process is not successfully decoded after the previous HARQ transmission (the UE feeds back a negative response (Negative-Acknowledgment, NACK)), after the drx-HARQ-RTT-Timer DL times out, the UE turns on the downlink retransmission timing of DRX timer (drx-RetransmissionTimer DL). If the data in the corresponding HARQ process is successfully decoded after the previous HARQ transmission (UE feedback response (Acknowledgment, ACK)), after the drx-HARQ-RTT-Timer DL timer expires, the UE does not start the drx-Retransmission Timer DL. If only drx-HARQ-RTT-Timer DL is currently running, the UE does not monitor the control channel.

HARQ retransmission timer (HARQ retransmission Timer): divided into the HARQ uplink retransmission timer (drx-RetransmissionTimer DL) of DRX or the HARQ downlink retransmission timer (drx-RetransmissionTimer UL) of DRX. In the following example, during the drx-RetransmissionTimer DL operation, the UE monitors the control signaling and waits for the retransmission scheduling of the corresponding HARQ process.

It can be seen from the above process that, in the On duration Timer, HARQ retransmission Timer and Inactivity Timer, if any timer is running, the UE will monitor the control channel. The time during which the UE monitors the control channel is also called the Active Time. Active Time is affected by other factors besides the DRX timer. For example, the Active Time of UE includes the following times: drx-onDuration Timer or drx-Inactivity Timer or drx-Retransmission Timer DL or drx-Retransmission Timer UL Or the running time of the random access contention resolution timer (ra-Contention ResolutionTimer).

The time that the UE waits for the base station to send the Physical Downlink Control Channel (PDCCH) after sending the Uplink Scheduling Request (SR);

The time for the non-contention random access UE to wait for the PDCCH scheduled by the cell radio network temporary identity (Cell Radio Network Tempory Identity, Cell RNTI, C-RNTI) after receiving the random access response (Random Access Response, RAR).

On duration calculation under DRX:

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

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

modulo(shortDRX-Cycle);

For long DRX cycle, the duration calculation formula is as follows:

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

in:

System Frame Number (SFN): the SFN number of the current radio frame;

Subframe number: the number of the current subframe;

shortDRX-Cycle: short DRX cycle;

longDRX-Cycle: long DRX cycle;

drxStartOffset: an offset value configured by radio resource control (Radio Resource Control, RRC) signaling.

Figure 3 is a schematic diagram of a direct communication link (Sidelink) discovery/communication; direct communication refers to a method in which adjacent terminals can transmit data through the Sidelink within a short range. The wireless interface corresponding to the Sidelink link is called the direct communication interface, also known as the Sidelink interface.

Specifically, the embodiments of the present disclosure provide a method and a terminal for processing the active state of a direct link, so as to solve the problem that the current DRX/DTX working mode of the direct link may not be able to perform information transmission due to transmission requirements, thereby causing The problem of causing the loss of transmission performance.

As shown in FIG. 4 , an embodiment of the present disclosure provides a method for processing a cut-through link activation state, including:

Step 41: The first terminal receives a first request for sending a channel state information (Channel State Information, CSI) report, or the first terminal generates a second request instructing the second terminal to send a CSI report, where the CSI report is a direct link channel Status information (Sidelink Channel State Information, SL-CSI) report;

Step 42: When the first condition is satisfied at the first moment, the first terminal enters the DRX or DTX activation state of the direct link at the first moment.

The above-mentioned first request for sending a CSI report may include: instructing the first terminal to send a CSI report (Sidelink Control Information, SCI), and the above-mentioned second request for instructing the second terminal to send a CSI report may include: : instructs the second terminal to send the SCI of the CSI report.

For example: the first terminal receives a first request for sending a CSI report, and when the first condition is met at the first moment, the first terminal enters the DRX activation state of the direct link at the first moment; or, the first terminal receives When the first request for sending the CSI report is satisfied at the first moment, the first terminal enters the DTX activation state of the direct link at the first moment.

Another example: the first terminal generates a second request instructing the second terminal to send a CSI report, and when the first condition is satisfied at the first moment, the first terminal enters the DRX activation state of the direct link at the first moment, or The first terminal generates a second request instructing the second terminal to send a CSI report, and when the first condition is satisfied at the first moment, the first terminal enters the DTX activation state of the direct link at the first moment.

Optionally, the first condition may be within a target time period after the first terminal receives the first request or generates the second request. For example, the first terminal may enter the DRX or DTX activation state of the cut-through link within a target time period after receiving the first request or generating the second request.

In this embodiment, when the first terminal receives the first request for sending the CSI report, or when the first terminal generates the second request instructing the second terminal to send the CSI report, when the first condition is satisfied at the first moment, the The first terminal enters the DRX or DTX activation state of the direct link at the first moment, so that the terminal can send and receive CSI reports in time when it is in a sleep state, thereby ensuring reliable transmission of information and reducing transmission performance loss .

Optionally, the DRX activation time includes at least one of the following:

The time period specified by the maximum delay limit of CSI;

Wherein, the time period specified by the maximum delay limit of the CSI may include: in the case where the medium access control control element (Medium Access Control Control Element, MAC CE) of the CSI report is not received, the maximum delay limit of the CSI is specified. time period. Alternatively, the time period specified by the maximum delay limit of the above CSI is not limited. The time period specified by the delay limit.

The first moment is the moment when the first terminal receives the first request to send the CSI report; or, the first moment is the moment when the first terminal receives the first request to send the CSI report, and the target time period has elapsed the moment

In other words, when the first condition is met at the first moment, the first terminal enters the discontinuous reception DRX or discontinuous transmission DTX activation state of the direct link at the first moment, including:

The first terminal enters the DRX or DTX activation state of the direct link at the moment of receiving the first request to send the CSI report.

That is, as an implementation manner: for each received first request, when the first terminal instructs the first terminal to send a CSI report in the first request, it can immediately enter the DRX or DTX active state, thereby ensuring that The terminal sends the CSI report in time, thereby ensuring reliable transmission of information and reducing the loss of transmission performance.

Or, when the first condition is satisfied at the first moment, the first terminal enters the discontinuous reception DRX or discontinuous transmission DTX activation state of the direct link at the first moment, including:

The first terminal starts from the moment of receiving the first request to send the CSI report, and enters the DRX or DTX activation state of the through link after the target time period has passed.

That is, as another implementation manner: for each received first request, when the first terminal instructs the first terminal to send a CSI report in receiving the first request, it may delay for a period of time (such as the delayed period of time). not exceeding the processing time for generating the CSI report) into the DRX or DTX activation state of the direct link, so that the terminal can ensure that the CSI report is sent in time, thereby ensuring reliable transmission of information and reducing the loss of transmission performance.

Start the CSI report timer of the SL port; wherein, the CSI report timer: a period of time after the first terminal receives the first request (that is, it can be implemented by defining a new timer, such as starting the newly defined CSI report of the SL port Timer (CSI report timer for DRX (drx-CSIReportTimer) or CSI report timer for DTX (dtx-CSIReportTimer)).

Optionally, the CSI reporting timer may be configured by PHY signaling; or, the CSI reporting timer may be configured by MAC signaling; or, the CSI reporting timer may be configured by RRC signaling.

Optionally, a new activation time may be defined, and when the first terminal receives the first request for sending the CSI report, under the first condition, it enters the DRX or DTX activation state of the direct link. For example, the activation time can be understood as a time period during which the first terminal is in the DRX or DTX activation state of the direct link.

Optionally, the activation time of DRX or DTX is: from the first moment to the moment when the first terminal sends the MAC CE of the CSI.

In other words, the active time (active time) of DRX or DTX may be: from the time when the first terminal receives the first request to the time when the MAC CE of the CSI is sent.

For example, the period from when the UE receives the first request to when it obtains a direct link grant (SL grant) for sending the CSI MAC CE and finally sends the CSI MAC CE is defined as DRX or DTX active time.

Alternatively, the activation time of DRX or DTX may be: from the first target moment to the moment when the CSI MAC CE is sent; wherein, the first target moment is from the moment when the first terminal receives the first request and passes the target time segment moment.

For example: a period of time after the UE receives the first request (for example, the period of time does not exceed the processing time for generating the CSI report), until it obtains the SL grant for CSI MAC CE transmission and finally sends the CSI MAC CE out. Time is defined as DRX or DTX active time.

Optionally, entering the discontinuous reception DRX or discontinuous transmission DTX activation state of the direct link at the first moment, including:

In this way, by changing the length of the DRX/DTX cycle, the longer DRX/DTX cycle is changed to a shorter DRX/DTX cycle, so as to shorten the length of the Sleep state, so that after the terminal sends the second request instructing the peer to generate a CSI report, It can enter the DRX/DTX active state within the processing time range of generating the CSI report and wait to receive the CSI report, so as to ensure that the terminal can receive the CSI report sent by the opposite end in time, thereby ensuring reliable transmission of information and reducing the loss of transmission performance.

At the moment of generating the second request instructing the second terminal to send the CSI report, the first terminal enters the DRX or DTX activation state of the through link, and changes the long DRX cycle of the through link to a short DRX cycle; or, changes the through link to a short DRX cycle; The long DTX cycle of the circuit is changed to a short DTX cycle.

Or, the first terminal starts from the moment of generating the second request instructing the second terminal to send the CSI report, and after the target time period passes, enters the DRX or DTX activation state of the through link, and changes the long DRX cycle of the through link to Short DRX cycle; or, change the long DTX cycle of the direct link to a short DTX cycle, and wait for the CSI report to be received, so as to further ensure that the terminal can receive the CSI report sent by the peer end in time, thereby ensuring reliable information transmission and reducing transmission performance. loss.

Then determine whether to execute. specific:

For example: in the current DRX/DTX cycle, if the latest activation time cannot meet the delay requirement of CSI report (that is, before the delay requirement of CSI report, the current DRX/DTX is always in sleep state), then the terminal executes the entry within the target time period. The step of discontinuous reception of DRX or discontinuous transmission of DTX active state of the direct link ensures that the terminal can send the CSI report in time or wait to receive the CSI report sent by the opposite terminal, thereby ensuring the reliable transmission of information and reducing the loss of transmission performance. And by judging that the current DRX or DTX cycle does not meet the maximum delay requirement of the CSI report, power consumption can also be reduced to a certain extent.
