Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method, an apparatus, and a terminal for processing a direct link activation state. Background Art

[0002] For a direct communication interface, a power saving mechanism is currently not supported, so the power consumption of the terminal is relatively fast. To solve the power consumption problem, a cellular network communication system adopts a discontinuous reception (DRX) operating mode. In this operating mode, the terminal periodically monitors the control channel, thereby achieving the purpose of power saving. However, in this operating mode, since the terminal periodically monitors the control channel, that is, the terminal continuously monitors the control channel during the on duration, and is in a sleep state during other times except the on duration and no longer monitors the control channel. In this way, when the terminal is in the DRX / discontinuous transmission (DTX) operating mode of the direct link, there may be a situation where information cannot be transmitted when there is a transmission requirement, thus causing a loss of transmission performance.

[0080] To make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present invention. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, descriptions of known functions and configurations are omitted for clarity and conciseness.

[0081] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0082] In the embodiments of the present application, the term "a plurality of" means two or more, and other quantifiers are similar.

[0083] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0084] As Figure 1 is a schematic diagram of a cellular communication network; in traditional cellular network communication, data and control information for up / downlink are transmitted between the terminal and the network-side device through the Uu interface.

[0085] In a mobile communication system based on a shared channel, such as Long Term Evolution (LTE), the transmission of uplink and downlink data is controlled by the base station (eNB) scheduler. When the scheduler determines to schedule a certain user, it will notify the terminal through the control channel on which resources to send or receive data. The terminal (UE) listens to the control channel. When it detects the scheduling information containing itself, it completes the data transmission (uplink) or reception (downlink) according to the indication on the control channel. In the active state, since the terminal is uncertain about when the eNB schedules it, a common working mode is that the terminal continuously listens to the control channel and parses each subframe containing its downlink scheduling control channel to determine whether it is scheduled. This working method can achieve higher efficiency when the terminal has a large amount of data and may be frequently scheduled. However, for some services, the arrival frequency of data is low, resulting in a small number of times the terminal is scheduled. If the terminal still continuously listens to the control channel, it will undoubtedly increase its power consumption. To solve the power consumption problem, the cellular network communication system adopts the DRX working mode. In this working mode, the terminal periodically listens to the control channel, thus achieving the purpose of power saving.

[0086] The basic principle of DRX is as Figure 2 shown. During the DRX cycle, the terminal UE shall monitor the PDCCH. Among them, the On duration represents the time period when the UE listens to the control channel. During this period, the radio frequency channel is turned on and the control channel is continuously listened to; during other times except the On duration (such as Opportunity for DRX), the UE is in the Sleep state, and its radio frequency link will be turned off and no longer listens to the control channel to achieve the purpose of power saving. The On Duration appears periodically (Cycle), and the specific cycle is implemented by the eNB configuration.

[0087] The DRX mechanism of the cellular network takes into account the arrival model of data services, that is, the arrival of data packets is bursty (it can be understood that once a data packet arrives, a relatively large number of packets will arrive continuously in a short period of time). To adapt to this service arrival characteristic, the DRX process adopts a variety of timers and combines with the Hybrid Automatic Repeat Request (HARQ) process to achieve better power saving performance.

[0088] The DRX-related timers are as follows:

[0089] The DRX on-duration timer: The time when the UE wakes up periodically to listen to the control channel, such asFigure 2 as shown

[0090] Short DRX cycle Timer: To better match the characteristics of data service arrivals, the cellular network communication system supports configuring two DRX cycles: a long cycle and a short cycle. The on duration timer for both cycles is 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 more quickly. The long cycle must be configured and is the initial state of the DRX process; the 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.

[0091] DRX Inactivity Timer: After configuring DRX, when the UE receives the control signaling of the HARQ initial transmission within the time allowed to listen to the control channel (Active Time), this timer is started. Before this timer times out, the UE continuously listens to the control channel. If the UE receives the control signaling of the HARQ initial transmission before the drx-InactivityTimer times out, the drx-InactivityTimer will be terminated and restarted.

[0092] HARQ Round Trip Time Timer (HARQ RTT Timer): It is divided into the HARQ Downlink Round Trip Time Timer for DRX (drx-HARQ-RTT-TimerDL) and the HARQ Uplink Round Trip Time Timer for DRX (drx-HARQ-RTT-TimerUL). The purpose is to enable the UE to avoid listening to the control channel before the next retransmission arrives, achieving a better power-saving effect. Taking the following behavior as an example, this timer is started at the first symbol after the transmission of the Physical Uplink Control Channel (PUCCH) of the UE-related process. If the data in the corresponding HARQ process is not successfully decoded after the previous HARQ transmission (the UE feedbacks NACK), after the DL HARQ RTT Timer times out, the UE turns on the drx-RetransmissionTimerDL. If the data in the corresponding HARQ process is successfully decoded after the previous HARQ transmission (the UE feedbacks ACK), after the drx-HARQ-RTT-TimerDL timer times out, the UE does not start the drx-RetransmissionTimerDL. If only the drx-HARQ-RTT-TimerDL is running currently, the UE does not listen to the control channel.

[0093] HARQ Retransmission Timer: It is divided into the HARQ Uplink Retransmission Timer for DRX (drx-RetransmissionTimerDL) or the HARQ Downlink Retransmission Timer for DRX (drx-RetransmissionTimerUL). Taking the following behavior as an example, during the operation of the DL HARQ retransmission Timer, the UE listens to the control signaling and waits for the retransmission scheduling of the corresponding HARQ process.

[0094] As can be seen from the above process, when any of the On duration Timer, HARQ retransmission Timer, and Inactivity Timer is running, the UE will listen to the control channel. The time when the UE listens to the control channel is also called the Active Time. The Active Time is affected by other factors in addition to the DRX timer. For example, the Active Time of the UE includes the following times: the running time of drx-onDurationTimer or drx-InactivityTimer or drx-RetransmissionTimerDL or drx-RetransmissionTimerUL or ra-ContentionResolutionTimer.

[0095] The time for the UE to wait for the base station to send the Physical Downlink Control Channel (PDCCH) after sending the uplink Scheduling Request (SR).

[0096] The time for the UE in non-competitive random access to wait for the PDCCH scheduled by the Cell Radio Network Temporary Identity (C-RNTI) after receiving the Random Access Response (RAR).

[0097] DRX onduration calculation:

[0098] For the short DRX cycle, the onduration calculation formula is as follows:

[0099] [(SFN * 10) + subframe number] modulo (shortDRX-Cycle) = (drxStartOffset)

[0100] modulo (shortDRX-Cycle);

[0101] For the long DRX cycle, the onduration calculation formula is as follows:

[0102] [(SFN * 10) + subframe number] modulo (longDRX-Cycle) = drxStartOffset:

[0103] Where:

[0104] SFN: The SFN number of the current radio frame;

[0105] Subframe number: The number of the current subframe;

[0106] shortDRX-Cycle: Short DRX cycle;

[0107] longDRX-Cycle: Long DRX cycle;

[0108] drxStartOffset: An offset value configured by RRC signaling.

[0109] Such as Figure 3 is a schematic diagram of sidelink discovery / communication; direct communication means that neighboring terminals can perform data transmission through a direct communication link (also called sidelink) within a short distance range. The radio interface corresponding to the sidelink is called a direct communication interface, also called a sidelink interface.

[0110] Specifically, embodiments of the present invention provide a method for processing the active state of a direct link and a terminal, so as to solve the problem that the current DRX / DTX working mode of the direct link may cause information transmission not to be possible when there is a transmission requirement, thereby resulting in a loss of transmission performance.

[0111] Such as Figure 4 As shown, embodiments of the present invention provide a method for processing the active state of a direct link, including:

[0112] Step 41: The first terminal receives an SCI indicating that the first terminal sends a CSI report, or the first terminal generates an SCI indicating that the second terminal sends a CSI report;

[0113] Step 42: When the first condition is met at the first moment, the first terminal enters the DRX or DTX active state of the direct link at the first moment.

[0114] For example: The first terminal receives an SCI indicating that the first terminal sends a CSI report. When the first condition is met at the first moment, the first terminal enters the DRX active state of the direct link at the first moment; or, the first terminal receives an SCI indicating that the first terminal sends a CSI report. When the first condition is met at the first moment, the first terminal enters the DTX active state of the direct link at the first moment.

[0115] For another example: The first terminal generates an SCI indicating that the second terminal sends a CSI report. When the first condition is met at the first moment, the first terminal enters the DRX active state of the direct link at the first moment, or the first terminal generates an SCI indicating that the second terminal sends a CSI report. When the first condition is met at the first moment, the first terminal enters the DTX active state of the direct link at the first moment.

[0116] Optionally, the first condition may be within a target time period after the first terminal receives or generates the SCI. For example, the first terminal may enter the DRX or DTX active state of the direct link within a target time period after receiving or generating the SCI.

[0117] In this embodiment, when the first terminal receives an SCI indicating that the first terminal sends a CSI report, or when the first terminal generates an SCI indicating that the second terminal sends a CSI report, by meeting the first condition at the first moment, the first terminal enters the DRX or DTX active state of the direct link at the first moment, so that when the terminal is in the sleep state, it can send and receive CSI reports in a timely manner, thereby ensuring reliable transmission of information and reducing loss of transmission performance.

[0118] Optionally, for the case where the first terminal receives the direct link control information SCI indicating that the first terminal sends the channel state information CSI report, the first moment meeting the first condition includes:

[0119] The first moment is the moment when the first terminal receives the SCI indicating that the first terminal sends a CSI report; or, the first moment is the moment after a target time period from the moment when the first terminal receives the SCI indicating that the first terminal sends a CSI report.

[0120] 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 active state of the direct link at the first moment, including:

[0121] The first terminal enters the DRX or DTX active state of the direct link at the moment when it receives the SCI indicating that the first terminal sends a CSI report.

[0122] That is, as an implementation method: for each received SCI, when the first terminal receives an indication in the SCI that the first terminal sends a CSI report, it can immediately enter the DRX or DTX active state, so as to ensure that the terminal can send the CSI report in a timely manner, thereby ensuring reliable transmission of information and reducing loss of transmission performance.

[0123] Alternatively, 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:

[0124] The first terminal starts from the moment of receiving the SCI indicating that the first terminal sends a CSI report, and after a target time period, enters the DRX or DTX activation state of the direct link.

[0125] Optionally, the target time period is less than or equal to the processing duration for generating the CSI report.

[0126] That is, as another implementation: for each received SCI, when the first terminal receives an indication in the SCI to send a CSI report, the first terminal can enter the DRX or DTX activation state of the direct link after a delay (e.g., the delay period does not exceed the processing duration for generating the CSI report), so as to ensure that the terminal can send the CSI report in time, thus ensuring reliable information transmission and reducing the loss of transmission performance.

[0127] Optionally, the target time period (such as the delay period mentioned in the above embodiment) can be configured by radio resource control (RRC) signaling; or, the target time period is configured by medium access control (MAC) signaling; or, the target time period is configured by port physical layer (PHY) signaling.

[0128] For example: when the first terminal enters the DRX or DTX activation state of the direct link, it can adopt the form of a timer, which can specifically include at least one of the following:

[0129] Start the direct link SL port duration timer (such as starting the SL port drx-onDurationTimer or dtx-onDurationTimer);

[0130] Start the SL port inactivity timer (such as starting the SL port drx-InactivityTimer or dtx-InactivityTimer);

[0131] Start the SL port CSI report timer; wherein, the CSI report timer: a period of time after the first terminal receives the SCI (i.e., it can be implemented by defining a new timer, such as starting the newly defined SL port drx-CSIReportTimer or dtx-CSIReportTimer, that is, the CSI report timer).

[0132] Optionally, the CSI reporting timer may be configured by PHY signaling; alternatively, the CSI reporting timer is configured by MAC signaling; alternatively, the CSI reporting timer is configured by RRC signaling.

[0133] Optionally, a new activation time period may be defined, and when the first terminal receives an SCI indicating that the first terminal is to send a CSI report, under a first condition, the first terminal enters the DRX or DTX activation state of the direct link. For example, this activation time period can be understood as the time period during which the first terminal is in the DRX or DTX activation state of the direct link.

[0134] Optionally, the activation time of DRX or DTX is: from the first moment to the moment when the first terminal sends the media access control control element (MAC CE) of the CSI.

[0135] In other words, the activation time of DRX or DTX can be: from the moment when the first terminal receives the SCI to the moment when the media access control control element (MAC CE) of the CSI is sent.

[0136] For example: The time period from when the UE receives the SCI until it obtains the direct link grant (SL grant) for CSI MAC CE transmission and finally sends out the CSI MAC CE is defined as the DRX or DTX active time.

[0137] Alternatively, the activation time of DRX or DTX can also be: from the first target moment to the moment when the CSI MAC CE is sent; where the first target moment is the moment starting from when the first terminal receives the SCI and after a target time period.

[0138] Optionally, the target time period is less than or equal to the processing duration for generating the CSI report.

[0139] For example: The time period from a certain time after the UE receives the SCI (such as this time period does not exceed the processing duration for generating the CSI report) until it obtains the SL grant for CSI MAC CE transmission and finally sends out the CSI MAC CE is defined as the DRX or DTX active time.

[0140] Optionally, entering the discontinuous reception (DRX) or discontinuous transmission (DTX) activation state of the direct link at the first moment includes:

[0141] Changing the long DRX cycle of the direct link to a short DRX cycle; or changing the long DTX cycle of the direct link to a short DTX cycle.

[0142] In other words, entering the discontinuous reception (DRX) or discontinuous transmission (DTX) activation state of the direct link at the first moment is achieved by changing the long DRX cycle of the direct link to a short DRX cycle, or changing the long DTX cycle of the direct link to a short DTX cycle.

[0143] In this way, by changing the DRX / DTX cycle length, changing the longer DRX / DTX cycle to a shorter DRX / DTX cycle to shorten the length of the Sleep state, enabling the terminal to enter the DRX / DTX activation state within the processing duration for generating the CSI report, so as to ensure that the terminal can send the CSI report in a timely manner, thereby ensuring the reliable transmission of information and reducing the loss of transmission performance.

[0144] Optionally, entering the discontinuous reception (DRX) or discontinuous transmission (DTX) activation state of the direct link at the first moment includes:

[0145] The first terminal enters the DRX or DTX activation state of the direct link and changes the long DRX cycle of the direct link to a short DRX cycle at the moment of receiving the SCI indicating that the first terminal sends a CSI report; or changes the long DTX cycle of the direct link to a short DTX cycle.

[0146] Or, starting from the moment when the first terminal receives the SCI indicating that the first terminal sends a CSI report and after a target time period, the first terminal enters the DRX or DTX activation state of the direct link and changes the long DRX cycle of the direct link to a short DRX cycle; or changes the long DTX cycle of the direct link to a short DTX cycle to further ensure that the terminal sends the CSI report in a timely manner, thereby ensuring the reliable transmission of information and reducing the loss of transmission performance.

[0147] Optionally, for the case where the first terminal generates the direct link control information (SCI) indicating that the second terminal sends channel state information (CSI) report, the first moment satisfying the first condition includes:

[0148] The first moment is the moment when the first terminal generates the SCI indicating that the second terminal sends a CSI report; or the first moment is the moment after a target time period starting from the moment when the first terminal generates the SCI indicating that the first terminal sends a CSI report.

[0149] In other words, when the first moment satisfies the first condition, the first terminal entering the discontinuous reception (DRX) or discontinuous transmission (DTX) activation state of the direct link at the first moment includes:

[0150] The first terminal enters the DRX or DTX activation state of the direct link at the moment of generating the SCI indicating that the second terminal sends a CSI report.

[0151] That is, as an implementation method: for each generated SCI, when the SCI indicates that the second terminal (or understood as the peer UE) sends a CSI report, the first terminal can immediately enter the DRX or DTX activation state and wait to receive the CSI report, so as to ensure that the terminal can receive the CSI report sent by the peer in time, thereby ensuring the reliable transmission of information and reducing the loss of transmission performance.

[0152] Alternatively, 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:

[0153] The first terminal starts from the moment of generating the SCI indicating that the second terminal sends a CSI report and enters the DRX or DTX activation state of the direct link after a target time period.

[0154] Optionally, the target time period is less than or equal to the processing duration of generating the CSI report.

[0155] That is, as another implementation method: for each generated SCI, when the SCI indicates that the second terminal sends a CSI report, the first terminal can enter the DRX or DTX activation state of the direct link after a delay (for example, the delay period does not exceed the processing duration 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 peer in time, thereby ensuring the reliable transmission of information and reducing the loss of transmission performance.

[0156] Optionally, the target time period (such as the delay period mentioned in the above embodiment) can be configured by RRC signaling; or, the target time period is configured by MAC signaling; or, the target time period is configured by PHY signaling.

[0157] For example: when the first terminal enters the DRX or DTX activation state of the direct link, it can adopt the form of a timer, which can specifically include at least one of the following:

[0158] Start the direct link SL port duration timer (such as starting the SL port drx-onDurationTimer or dtx-onDurationTimer);

[0159] Start the SL port inactivity timer (such as starting the SL port drx-InactivityTimer or dtx-InactivityTimer);

[0160] Start the SL interface CSI report timer; where the CSI report timer is a period of time after the first terminal sends the SCI (i.e., it can be implemented by defining a new timer, such as starting a newly defined drx-CSIReportTimer or dtx-CSIReportTimer for the SL interface, that is, the CSI report timer).

[0161] Optionally, the CSI report timer can be configured by PHY signaling; or, the CSI report timer is configured by MAC signaling; or, the CSI report timer is configured by RRC signaling.

[0162] Optionally, a new activation time can be defined, and when the first terminal generates an SCI indicating that the second terminal sends a CSI report, it enters the discontinuous reception DRX or discontinuous transmission DTX activation state of the direct link at the first moment. For example, this activation time can be understood as the time period when the first terminal is in the DRX or DTX activation state of the direct link.

[0163] Optionally, the activation time of DRX or DTX is: from the first moment to the moment when the first terminal receives the CSI report.

[0164] In other words, the activation time of DRX or DTX can be: from the moment when the first terminal sends the SCI to the moment when it receives the CSI report.

[0165] This activation time is defined as the DRX or DTX active time from the time when the UE sends the SCI to the time when it receives the CSI report.

[0166] Or, the activation time of DRX or DTX can also be: from the second target moment to the moment when the CSI report is received; where the second target moment is the moment after a target time period starting from the moment when the first terminal sends the SCI.

[0167] Optionally, the target time period is less than or equal to the processing duration for generating the CSI report.

[0168] This activation time is defined as the DRX or DTX active time from a time period (such as this time does not exceed the processing duration for generating the CSI report) after the UE sends the SCI to the time when it receives the CSI report.

[0169] Optionally, entering the discontinuous reception DRX or discontinuous transmission DTX activation state of the direct link at the first moment includes:

[0170] Changing the long DRX cycle of the direct link to a short DRX cycle; or, changing the long DTX cycle of the direct link to a short DTX cycle.

[0171] In other words, entering the discontinuous reception (DRX) or discontinuous transmission (DTX) activation state of the direct link at the first moment is achieved by changing the long DRX cycle of the direct link to a short DRX cycle, or changing the long DTX cycle of the direct link to a short DTX cycle.

[0172] In this way, by changing the DRX / DTX cycle length, changing the longer DRX / DTX cycle to a shorter DRX / DTX cycle to shorten the length of the Sleep state, so that after the terminal sends the SCI indicating that the peer generates the CSI report, it can enter the DRX / DTX activation state within the processing duration of generating the CSI report and wait to receive the CSI report, thereby ensuring that the terminal can receive the CSI report sent by the peer in a timely manner, further ensuring the reliable transmission of information, and reducing the loss of transmission performance.

[0173] Optionally, entering the discontinuous reception (DRX) or discontinuous transmission (DTX) activation state of the direct link at the first moment includes:

[0174] The first terminal enters the DRX or DTX activation state of the direct link at the moment of generating the SCI indicating that the second terminal sends the CSI report, and changes the long DRX cycle of the direct link to a short DRX cycle; or changes the long DTX cycle of the direct link to a short DTX cycle.

[0175] Or, starting from the moment when the first terminal generates the SCI indicating that the second terminal sends the CSI report and after a target time period, the first terminal enters the DRX or DTX activation state of the direct link, and changes the long DRX cycle of the direct link to a short DRX cycle; or changes the long DTX cycle of the direct link to a short DTX cycle, and waits to receive the CSI report, thereby further ensuring that the terminal can receive the CSI report sent by the peer in a timely manner, further ensuring the reliable transmission of information, and reducing the loss of transmission performance.

[0176] Optionally, the step of the above terminal entering the discontinuous reception (DRX) or discontinuous transmission (DTX) activation state of the direct link within the target time period can also be determined after judging whether the current DRX / DTX cycle meets the maximum time delay requirement of the CSI report. Specifically:

[0177] If the current DRX or DTX cycle does not meet the maximum time delay requirement of the CSI report, then when the first condition is met at the first moment, the first terminal enters the DRX or DTX activation state of the direct link at the first moment.

[0178] For example, in the current DRX / DTX cycle, if the most recent activation time cannot meet the latency requirement of the CSI report (i.e., the current DRX / DTX has been in the sleep state before the latency requirement of the CSI report), the terminal performs the steps of entering the discontinuous reception DRX or discontinuous transmission DTX activation state of the direct link within the target time period, so as to ensure that the terminal can send the CSI report in time or wait to receive the CSI report sent by the peer end, thereby ensuring the reliable transmission of information and reducing the loss of transmission performance. And when it is determined that the cycle of the current DRX or DTX does not meet the maximum latency requirement of the CSI report, the power consumption can also be reduced to a certain extent.

[0179] The above method of the present invention will be described below in conjunction with specific embodiments:

[0181] When DRX is configured, the MAC entity performs the following process:

[0182] 1. When the UE receives an SCI, for each SCI, the following judgment is made:

[0183] 2. If the SCI contains information indicating that the UE sends a CSI report, then immediately or after a fixed delay (e.g., the delay time can be less than or equal to the processing duration of generating the CSI report, and the delay time can be obtained through RRC / MAC / PHY signaling), the following steps are performed:

[0184] 3. Obtain the earliest activation time in the current DRX / DTX cycle. If the earliest activation time cannot meet the maximum latency requirement of the CSI report, then at least one of the following steps can be performed:

[0197] 3-3. Stop the SL port drx-longCycleTimer and enable the short DRX / DTX cycle.

[0198] It should be noted that if the SCI contains information indicating that the peer UE is to send a CSI report, the determination of whether the earliest time to enter the active state meets the maximum time delay requirement for the CSI report can be made first, and at least one of the above items 3-1 to 3-4 is executed immediately or after a fixed time delay.
