Description

Information transmission method, resource scheduling method, device, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a resource scheduling method, an apparatus, a terminal, and a network device.

Background

In the prior art, for direct communication multicast and broadcast, whether to use the SL DRX (Discontinuous Reception) and/or DTX (Discontinuous Transmission) mechanism of the direct communication interface depends on the transmitting terminal. For example, if the sending terminal determines that the data to be sent is for a terminal supporting Rel-17 version and a terminal supporting Rel-16 version at the same time, the SL DRX may not be used; SL DRX may be used if the transmitting terminal determines that data currently to be transmitted is for terminals supporting Rel-17 release only.

Since whether SL DRX/DTX is used depends on a transmitting terminal, and the network side device does not know, for a terminal in an RRC (Radio Resource Control) connected state and using a network scheduled Resource allocation mode (mode 1) of a direct communication interface transmitting terminal, the network side device cannot accurately determine DRX and/or DTX Active Time (Active Time) of the terminal on the direct communication interface, and therefore cannot reasonably schedule resources of the direct communication interface, which may result in a decrease in Resource utilization of the direct communication interface.

Detailed Description

The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that, in the conventional cellular network communication, uplink/downlink data and control information are transmitted between the terminal and the network side device through the Uu interface.

The DRX mechanism of the Uu interface of the cellular communication system is as follows:

in a mobile communication system based on a shared channel, transmission of uplink and downlink data is controlled by a base station scheduler, and when the scheduler determines to schedule a user, the scheduler informs a terminal of what resource to transmit or receive data on through a control channel.

The terminal (UE) monitors the control channel, and when the terminal detects that the terminal contains the scheduling information of the UE, the terminal completes the transmission or the reception of data according to the indication on the control channel. In the active state, since the terminal does not determine when it is scheduled by the base station (eNB), one common mode of operation is:

the terminal continuously monitors the control channel and analyzes each subframe containing the downlink scheduling control channel to judge whether the subframe is scheduled or not.

The working mode can obtain higher efficiency under the condition that the terminal has larger data volume and is possibly scheduled frequently. 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 will undoubtedly increase its power consumption if the terminal is still continuously listening 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 basic principles of DRX are described below to facilitate a better understanding of the method of the present invention.

As shown in fig. 1, wherein, the On Duration represents a time period for the UE to monitor the control channel, during which the radio frequency channel is opened and the control channel is continuously monitored; at other times (Opportunity for DRX) 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.

It should be noted that the DRX mechanism of the cellular network 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, multiple timers are adopted in the LTE DRX process and combined with an HARQ (Hybrid Automatic Repeat reQuest) process to achieve better power saving performance.

Wherein, with respect to the DRX-related timer:

1) drx-onDurationTimer: the time when the UE periodically wakes up to monitor the control channel;

2) Short DRX 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 onDurationTimer 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 faster. The 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 DRX cycle Timer times out, the UE will use the long cycle.

3) drx-inactivytytimer: after the DRX is configured, when the UE receives the control signaling for HARQ initial transmission within a Time allowed to monitor the control channel (Active Time), the timer is turned on, 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.

4) HARQ RTT Timer: the timer is divided into drx-HARQ-RTT-TimerDL and drx-HARQ-RTT-TimerUL, and aims to ensure that the UE does not monitor the control channel before the next retransmission arrives, thereby achieving better power saving effect.

Following behavior example, the first symbol after PUCCH transmission for UE-related processes starts, 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 NACK), the UE opens drx-retransmission TimerDL after the drx-HARQ-RTT-TimerDL is overtime.

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.

5) HARQ Retransmission Timer: classified as drx-retransmission timerdl or drx-retransmission timerll.

As an example of the following behavior, during the drx-retransmission timerdl operation, the UE monitors the control signaling and waits for the retransmission scheduling of the corresponding HARQ process.

Through the above process, it can be seen that any one of the On duration Timer, HARQ Retransmission Timer, and Inactivity Timer is running, and the UE will monitor the control channel. The Time when the UE listens to the control channel is also called Active Time, which may also be called activation Time. In addition to being influenced by the DRX timer, active Time in the LTE system includes the following Time:

the time that drx-onDurationTimer, drx-inactivytimer, drx-retransmission timerdl, drx-retransmission timerlor ra-contentionresolutiontiimer runs;

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

and after receiving the RAR (Random Access Response), the non-contention Random Access UE waits for the time of the PDCCH scheduled by the C-RNTI.

It should be noted that the direct communication is a method in which a neighboring terminal can perform data transmission through a direct communication link (also referred to as Sidelink) in a short distance range. The wireless interface to which the sildelink link corresponds is referred to as a direct communication interface, also referred to as a sildelink interface.

The direct communication interface resource allocation modes are divided into two types:

resource allocation mode for network scheduling (also referred to as mode 1): the network side equipment allocates resources used for sending the direct communication interface data for the terminal;

terminal-selected resource allocation mode (also called mode 2): i.e. the direct communication transmission resources are selected by the terminal itself from a pool of resources available to the direct communication interface.

According to the current mechanism, whether SL DRX/DTX is used or not for direct communication multicast and broadcast depends on a sending UE, but the network does not know, so that for the UE in an RRC connection state and sending UE by using a direct communication interface of a resource allocation mode (mode 1) scheduled by the network, a network side device cannot accurately determine the DRX and/or DTX activation time of the terminal on the direct communication interface, and therefore the direct communication interface resource cannot be reasonably scheduled for the terminal.

In order to solve the above problems, embodiments of the present application provide a resource scheduling method and apparatus, where the method and apparatus are based on the same application concept, and because the principles of the method and apparatus for solving the problems are similar, the apparatus and method may be implemented by referring to each other, and repeated parts are not described again.

As shown in fig. 2, a schematic flow chart of a resource scheduling method provided in the embodiment of the present invention is applied to a terminal, and includes:

step 201: the terminal sends indication information to network side equipment, wherein the indication information is used for indicating the use condition of the terminal on a direct communication interface SL DRX and/or SL DTX.

Here, the terminal is a through-link terminal using a resource allocation mode (mode 1) of network scheduling.

It should be noted that the indication information is used for indicating the use condition of the terminal in the SL DRX and/or the SL DTX. Specifically, the indication information is used to indicate whether a target object related to the terminal direct communication uses SL DRX and/or SL DTX, where the target object includes one of:

a direct communication interface;

a direct communication interface destination address;

a direct communication interface destination address list;

a direct communication interface QoS profile or a QoS profile list;

and if the terminal is determined to use the SL DRX and the SL DTX on the direct communication interface, determining corresponding SL DRX configuration and SL DTX configuration of each QoS profile or QoS profile list under each target address of the terminal.

For the following explanation of the meaning of "and/or" in the embodiments, reference may be made to the embodiments, which will not be described in detail later.

the method comprises the following specific steps:

according to SL DRX configuration, determining SL DRX activation time corresponding to each QoS profile or QoS profile list under each target address of the terminal;

according to SL DTX configuration, determining the SL DTX activation time corresponding to each QoS profile or QoS profile list under each target address of the terminal;

and determining the SL DRX activation time and the SL DTX activation time corresponding to each QoS profile or QoS profile list under each target address of the terminal according to the SL DRX configuration and the SL DTX configuration.

Here, the SL DRX active time refers to a time when the terminal is allowed to monitor a control channel and/or perform data reception at the direct communication interface.

The SL DTX active time refers to a time that the terminal is allowed to transmit control information and/or data on the direct communication interface.

In this way, the network device can accurately determine the DRX and/or DTX activation time of the terminal at the direct communication interface.

Here, the SL DRX activation time and/or the SL DTX activation time may be accurately determined by the network side device according to the indication information, where the SL DRX activation time and/or the SL DTX activation time corresponds to each QoS profile or the QoS profile list at each target address of the terminal direct communication interface, and the network side device may reasonably perform scheduling of the direct communication interface on the terminal, thereby improving resource utilization of the direct communication interface.

if at least part of the target addresses of the direct communication interfaces of the terminal are determined to use SL DRX and/or SL DTX according to the indication information, or a direct communication interface target address list of the SL DRX and/or SL DTX is determined to be used by the terminal according to the indication information, determining corresponding SL DRX configuration and/or SL DTX configuration for each QoS profile or QoS profile list under each target address of the SL DRX and/or SL DTX used by the terminal;

here, according to practical situations, it may be required that a part of the target addresses use SL DRX and/or SL DTX and a part of the target addresses do not use SL DRX and/or SL DTX.

Or, according to the actual situation, determining the direct communication interface target address list of the terminal using the SL DRX and/or the SL DTX based on the indication information.

Here, according to the accurately determined time that the terminal is allowed to monitor the control channel at the direct communication interface, that is, the SL DRX activation time and/or the SL DTX activation time corresponding to each QoS profile or the QoS profile list at each target address where the terminal uses the SL DRX and/or the SL DTX, the network side device can reasonably perform scheduling of the direct communication interface for the terminal, and improve the resource utilization rate of the direct communication interface.

here, as the case may be, it may be required that a part of the QoS profile or the QoS profile list uses the SL DRX and/or the SL DTX, and a part of the QoS profile or the QoS profile list does not use the SL DRX and/or the SL DTX.

The SL DTX active time refers to a time when the terminal is allowed to transmit control information and/or data on the direct communication interface.

Here, the network side device can accurately determine each QoS profile using the SL DRX and/or SL DTX or SL DRX activation time and/or SL DTX activation time corresponding to the QoS profile list under each target address of the terminal direct communication interface according to the indication information, thereby ensuring that the network side device can reasonably perform scheduling of the direct communication interface for the terminal, and improving resource utilization rate of the direct communication interface.

here, as a practical matter, it is possible that the terminal has only a part of the QoS profile or QoS profile list in a part of the destination addresses using SL DRX and/or SL DTX, while another part of the QoS profile or QoS profile list of the terminal does not use SL DRX and/or SL DTX.

Here, the network device may determine which QoS profiles or QoS profile lists under which destination addresses of the direct communication interface use SL DRX and/or SL DTX according to the indication information. Therefore, the activation time of the QoS profile under the target address using the SL DRX and/or the SL DTX or the SL DRX activation time and/or the SL DTX activation time corresponding to the QoS profile list can be determined according to the SL DRX and/or DTX configuration, so that the network side equipment can reasonably execute the scheduling of the direct communication interface to the terminal, and the resource utilization rate of the direct communication interface is improved.

if the terminal is determined not to use SL DRX and/or SL DTX on the direct communication interface according to the indication information, scheduling any direct communication interface logic channel belonging to the terminal on all available resources of the direct communication interface;
