Description

Communication method, device and system

The present application claims priority from a chinese patent application filed by the national intellectual property office on 04/06/2020, having application number 202010501831.2 entitled "a method and UE for providing auxiliary information", the entire contents of which are incorporated herein by reference.

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a communication method, device and system.

Background

In a Long Term Evolution (LTE) system or a New Radio (NR) system, data may be transmitted between terminals through sidelink resources. When a terminal a is used as a sender terminal (Tx UE) to send traffic data to a receiver terminal (Rx UE), the sender terminal may sense (sensing) one or more sidelink resources in a resource pool to determine at least one target sidelink resource a. When the terminal a serves as a receiving terminal to receive the service data from the sending terminal, the terminal a can also sense one or more sidelink resources in the resource pool to determine at least one target sidelink resource b. The difference is that the target sidelink resource a is used for the terminal a to transmit the service data, and the target sidelink resource b is used for the terminal a to receive the service data, but the above manner can ensure the communication quality of the terminal a no matter whether the terminal a transmits or receives the service data.

However, currently, the terminal a does not always receive the service data during the whole time period, and currently, in the prior art, the terminal a is in a sensing state regardless of whether the terminal a has data reception during the whole time period. This causes excessive power consumption of the terminal a.

Disclosure of Invention

The embodiment of the application provides a communication method, device and system, which are used for ensuring that the power consumption is reduced and simultaneously ensuring the data transmission quality of a terminal.

In order to achieve the above object, the following technical solutions are provided in the embodiments of the present application:

in a first aspect, an embodiment of the present application provides a communication method, where the method includes: the first terminal receives configuration information of a first discontinuous reception, DRX, configuration and/or first time resource from the communication device. Wherein the first DRX configuration includes configuration information of a first inactive period. The configuration information of the first inactive period is used for indicating that the first terminal is in an inactive state in the first inactive period, the first time resource is a time resource of the first terminal sensing sidelink resource, and the communication device includes a second terminal and/or a network device. When the first inactive period conflicts with the first time resource, the first terminal sends first information to the communication equipment, wherein the first information is used for indicating that the first inactive period conflicts with the first time resource.

The embodiment of the present application provides a communication method, which may be configured to notify, by a first terminal, a communication device that a first inactive period conflicts with a first time resource by using first information, when a DRX mechanism of the first terminal and the first time resource for sensing a sidelink resource conflict. Since the first inactive period and the first time resource indicate that the sidelink resource may need to be sensed when the first terminal is in an inactive state, but actually, the first terminal cannot detect the psch-RSRP and RSSI measurements when the first terminal is in an inactive state, and therefore, the procedure of sensing the sidelink resource cannot be realized. Therefore, the first terminal sends the first information to the communication device, so that the communication device can adjust or cancel the DRX configuration of the first terminal in time, and/or cancel or adjust the configuration information of the first time resource, thereby avoiding the conflict between the sensing sidelink resource and the inactive period of the first terminal, and ensuring the data transmission of the first terminal while reducing the power consumption by adopting the DRX configuration.

In a possible implementation, the first information is further used to indicate to adjust an inactivity period of the first terminal. Therefore, the same information can be used for indicating the conflict and the adjustment of the inactive period of the first terminal.

In a possible implementation manner, the method provided in the embodiment of the present application further includes: the first terminal sends the second information to the communication device. The second information is used for indicating to adjust the inactivity period of the first terminal. The scheme may enable the indication of the first terminal using the second information that the communication device is expected to adjust the inactivity period of the first terminal.

In a possible implementation manner, the method provided in the embodiment of the present application further includes: the first terminal transmits the third information to the communication device. The third information is information indicating a second inactive period. The second inactive period is an inactive period desired by the first terminal. A time period is facilitated for the communications device to reconfigure the first terminal with the aware sidelink resources according to the desired period of inactivity for the first terminal.

In one possible implementation, the second inactive period and the first time resource do not conflict. Therefore, the purpose of saving power consumption of the first terminal can be achieved, and the purpose of sensing side link resources can be achieved.

In a possible implementation manner, when the first terminal instructs the communication device to adjust the inactive period of the first terminal, the method provided in the embodiment of the present application further includes: the first terminal maintains an awake state for a first inactive period. In one aspect, the first terminal may autonomously decide to maintain the awake state for the first period of inactivity regardless of whether the second information and the third information are transmitted to the communication device. On the other hand, the first terminal finds that the conflict exists, and the first terminal determines to maintain the awakening state in the first inactive period after the first terminal sends the second information or the third information to the communication device. It is noted that maintaining the awake state of the first terminal during the first inactive period can sense the sidelink resource at the first time resource.

In a possible implementation manner, before the first terminal maintains the awake state during the first inactive period, the method may further include: the first terminal determines to maintain the awake state for a first inactive period.

In one possible implementation, the determining, by the first terminal, that the awake state is maintained for the first inactive period includes: the first terminal receives a first indication from the communication device, the first indication being used for the first terminal to determine that the communication device agrees to maintain the awake state for the first inactive period. The first terminal determines that the communication device agrees that the first terminal maintains the wake-up state in the first inactive period according to the first indication. For example, the first indication may be an indication to cancel the DRX configuration of the first terminal, or the first indication may be an indication to allow the first terminal to maintain the awake state during the first inactive period. That is, when the first terminal indicates that the collision exists to the communication device by using the first information, the communication device may send the first indication to the first terminal.

In one possible implementation, the determining, by the first terminal, that the awake state is maintained for the first inactive period includes: the first terminal determines according to a predefined protocol that the first terminal can maintain the awake state for a first inactive period upon occurrence of a conflict between the time resources of the cognitive sidelink resources and the inactive period of the first terminal.

In a possible implementation manner, the method provided in the embodiment of the present application further includes: the first terminal enters an inactive state during a second inactive period. In one aspect, once the first terminal has sent the information of the second inactive period to the communication device, the first terminal enters the inactive state during the second inactive period regardless of whether the communication device sends an indication 1 that allows the first terminal to enter the inactive state during the second inactive period. On the other hand, after the first terminal transmits the information of the second inactive period to the communication device, if the first terminal receives the indication 1 from the communication device, the first terminal enters the inactive state during the second inactive period.

In one possible implementation, the first information is further used to indicate that the first DRX configuration to be configured for the first terminal is cancelled or invalid.

In a possible implementation manner, the method provided in the embodiment of the present application further includes: the first terminal sends the fourth information to the communication device.

The system architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

The technical scheme of the embodiment of the application can be applied to various communication systems. For example: global system for mobile communications (GSM), evolved universal radio access (E-UTRA) systems, Universal Mobile Telecommunications System (UMTS), and next generation communication systems such as UMTS evolution, Long Term Evolution (LTE) and various versions based on LTE evolution, fifth generation (5th-generation, 5G) communication systems, and new air interfaces (NR). In addition, the communication system can also be applied to future-oriented communication technologies, and all the communication technologies are applied to the technical solutions provided by the embodiments of the present application.

Before describing the embodiments of the present application, the terms referred to in the embodiments of the present application will be explained as follows:

1) sidelink (SL) means: defined for terminals and direct communication between terminals. I.e. a link between the terminal and the terminal that communicates directly without relaying through the base station.

2) The sidelink resource refers to: and resources used when the side link service data and the control information are transmitted on the side link between the terminals.

3) And the side link service data refers to: and the service data or the control information transmitted by any two terminals on the sidelink.

4) Discontinuous Reception (DRX), refers to turning on a receiver by a terminal only for a necessary time to enter an active state (which may also be referred to as an active state) to receive downlink data and signaling. And at other times turning off the receiver into a sleep state (which may also be referred to as an inactive state). And when the terminal is in a dormant state, the terminal stops receiving downlink data and signaling. DRX is an operation mode of the terminal that saves power consumption of the terminal. DRX is divided into idle DRX and connected DRX. Idle DRX is implemented by sensing the paging channel since there is no RRC connection and no terminal-specific bearer. The connected DRX refers to a DRX characteristic when the terminal is in an RRC connected state, and is implemented by monitoring a Physical Downlink Control Channel (PDCCH). The diagram of the DRX mechanism is shown in fig. 1, and in the time domain, the time is divided into continuous DRX cycles (DRX cycles). The DRX cycle includes an active period (which is timed with a DRX duration timer) and an inactive period. During the active period, the terminal perceives PDCCH or Physical Sidelink Control Channel (PSCCH). In the inactive period, the terminal does not sense and receive the downlink signal, so as to save power consumption. DRX duration timer refers to: the DRX cycle begins with an on duration, during which the DRX on duration timer runs, the terminal is in an awake state (which may also be referred to as an active state).

Typical application scenarios for DRX include the following categories: the method is insensitive to time delay, and services such as browsing web pages, emails and FTP which need to receive and send data are not available at most times. A service that generates rare packets, such as a Presence service. Periodic continuous packet traffic, such as voip (voice over ip) traffic, Automatic Neighbor Relation (ANR) measurement.

As shown in fig. 1, the DRX Cycle is a discontinuous reception Cycle, and the terminal wakes up periodically in each Cycle to receive data. There are two types of DRX cycles: a long period (as shown in (a) of fig. 1) and a short period (as shown in (b) of fig. 1), the long period being an integral multiple of the short period. drx-onDurationTimer is a continuous downlink subframe number, and the terminal needs to sense the PDCCH or PSCCH in the continuous downlink subframe number, which indicates the time for the terminal to stay in the awake state after waking up. The timer is started at the beginning of each DRX cycle.

5) The active period refers to a time when a DRX-onDurationTimer is running at the start of one DRX cycle defined in the standard, and the terminal is in an active state (may also be referred to as an awake state or an active state) during the active period.

6) The inactive period refers to a time after expiration of a DRX on duration timer in one DRX cycle defined in the standard, and the terminal is in an inactive state (may also be referred to as a sleep state) in the inactive period.

7) The awake state refers to a state in which the terminal can listen to the service data, that is, a state when receiving the data, and is a variable concept. In the awake state, the terminal needs to detect the PDCCH or PSCCH. The PSCCH is used to indicate a time-frequency domain resource location, a modulation and coding scheme, a priority of data carried in a side-link data channel (PSCCH), and the like of PSCCH transmission, and the PSCCH is used to carry data.

Wherein the wake-up state of a terminal comprises the wake-up state of the terminal during the active period. Or the awakening state of one terminal comprises the awakening state of the terminal in the inactive period and the awakening state in the time corresponding to the timing of other timers for maintaining the awakening state.

It should be noted that, if no other timer for maintaining the awake state is started, the awake state is the state of the terminal during the active period of the terminal. The inactive state is a state in which the terminal is in during an inactive period.

If the terminal has other timers for maintaining the awakening state to be started, the awakening state of the terminal not only comprises the awakening state of the terminal in the active period, but also comprises the awakening state in the time corresponding to the timing of the other timers for maintaining the awakening state.

8) And in the inactive state, the terminal cannot monitor service data (possibly other data), and the terminal does not perform PDCCH or PSCCH detection in the inactive state so as to save electric quantity.

The inactive state is the state of the terminal during the inactive period minus the duration of the other timers that maintain the awake state.

9) In LTE V2X, before sending traffic data on the sidelink, the sending terminal may use a sensing technique to determine the sidelink resource required for sending traffic data. The conventional steps of sensing and resource reservation are to set a sliding sensing window, during which the transmitting terminal continuously demodulates and measures the control information of the transmitting terminal and the energy of the pscch.

As shown in fig. 2, fig. 2 takes a process of sensing sidelink resources by a sender terminal as an example, and the process includes:

step 201, the transmitting terminal continuously decodes other terminal SAs and measures the conformed physical Sidelink shared Channel (psch) energy (keep decoding other UEs' SA and measuring correlated psch energy).

Step 202, the sender terminal collects the sensing information located in the sliding sensing window, wherein the sensing information includes PSSCH-Reference Signal Receiving Power (RSRP) and Side-Received Signal Strength Indicator (S-RSSI) measurement.

Step 203, the sender terminal excludes the sidelink resources with energy higher than the preset energy threshold and forms a candidate sidelink resource set.

Step 204, the sender terminal selects a target resource from the candidate sidelink resource set and periodically transmits data on the target sidelink resource.

Step 205, if the sender terminal determines that the sidelink resource needs to be reselected, then step 202 is executed. If the sender terminal determines that the sidelink resources do not need to be reselected, step 204 is performed.

For the receiving terminal, if the purpose of the receiving terminal to perceive the sidelink is for the transmitting terminal to transmit data, step 204 may be replaced by: the receiving terminal selects the target resource from the candidate side link resource set, and then sends the information of the target resource to the sending terminal. It should be noted that when the receiver terminal senses the sidelink resource, the sender terminal in the above steps 201 to 204 needs to be replaced by the receiver terminal.

In order to improve the safety and intelligence of the traffic system, the system concept of intelligent traffic is gradually created. In the near phase, the development of intelligent transportation systems will mainly focus on the field of intelligent road transportation systems, namely the vehicle to electric (V2X). V2X communication includes Vehicle to Vehicle (V2V) communication, Vehicle to roadside Infrastructure (V2I) communication, and Vehicle to pedestrian (V2P) communication. The application of V2X will improve driving safety, reduce congestion and vehicle energy consumption and improve traffic efficiency. Such as communications with traffic lights, school districts, and railroad crossings. The vehicle networking system is a sidelink transmission technology based on Long Term Evolution (LTE) V2V or new air interface V2V, and is different from a traditional LTE system or a mode in which communication data in NR is received or transmitted through network equipment, and the vehicle networking system adopts a mode of direct terminal-to-terminal communication.

As communication technology evolves, the internet of Everything is also accelerating, and 3GPP introduced support for V2V and V2X (Vehicle-to-evolution) services in LTE during releases 14 and 15 in order to extend the 3GPP platform to the automotive industry. NR V2X will complement LTE V2X to enable advanced V2X services and support interworking with LTE V2X.

In sidelink, data may be transmitted directly between two terminals (e.g., a sender terminal and a receiver terminal). Therefore, the terminal of the sending party does not need to send the data to the base station first, and then to the terminal of the receiving party through the forwarding of the core network. Data latency can be greatly reduced.

Fig. 3 shows a scenario of sidelink communication, where fig. 3 shows a communication system provided in an embodiment of the present application, and the system includes: a transmission side terminal (Tx UE)10, a reception side terminal (Rx UE)20, and a terminal 30. It should be understood that 1 sender terminal 10, receiver terminal 20, and terminal 30 are shown in fig. 3.

The receiving terminal 20 in the embodiment of the present application refers to a terminal capable of receiving the service data transmitted by the transmitting terminal 10, and of course, the receiving terminal 20 may transmit the service data in addition to receiving the service data. The sender terminal 10 refers to a terminal capable of sending service data, and of course, the sender terminal 10 may also receive service data sent by other devices (such as the terminal 30 or the network device 40) besides sending service data. The sender terminal and the receiver terminal are relative concepts.

It is to be understood that in the embodiment of the present application, the sender terminal 10 and the receiver terminal 20 are capable of performing sidelink communication, and one or more of the sender terminal 10 and the receiver terminal 20 adopt a power saving mode, that is, the sender terminal 10 or the receiver terminal 20 includes an inactive period and an active period in one cycle.

The terminal 30 is used to configure a DRX configuration for the sender terminal 10 or the receiver terminal 20 and/or to perceive time resources for sidelink resources. In fig. 3, taking the receiver terminal 20 and the sender terminal 10 as an example of communication with the same terminal 30, in an actual process, the DRX configuration is configured for the receiver terminal 20 and the sender terminal 10, and/or a terminal for sensing time resources of sidelink resources may be different terminals. For example, the terminal 30 configures the DRX configuration for the sender terminal 10 and/or the time resources for sensing the sidelink resources. For example, the terminal 30 configures the DRX configuration for the receiver terminal 20 and/or the time resources for sensing the sidelink resources. It should be noted that, a terminal configured with DRX configuration for the receiving terminal 20 (or the sending terminal 10) and a terminal configured with time resources for sensing sidelink resources may be the same terminal or different terminals, which is not limited in this embodiment of the present application.

It is noted that the terminal 30 may be omitted when the DRX configuration of the receiver terminal 20, and/or the time resources for sensing sidelink resources are configured by the sender terminal 10.

In one possible implementation, the communication system may further include: network device 40. Wherein, the network device 40 has a second interface (for example, Uu interface) with the sender terminal 10, the receiver terminal 20, and the terminal 30. Wherein, the user plane of the Uu interface mainly transmits user data; the control plane transmits related signaling, and establishes, reconfigures and releases various mobile communication radio bearer services.

The network device 40 is configured to configure DRX configurations (e.g., inactive periods and active periods) for the sender terminal 10 or the receiver terminal 20, and/or to perceive time resources for sidelink resources. When the network device 40 is included in the communication system, if both the time resource and the DRX configuration of the cognitive sidelink resource of the sender terminal 10 (or the receiver terminal 20) are configured by the network device 40, the terminal 30 may be omitted. Of course, when the network device 40 is included in the communication system, if the DRX configuration of the sender terminal 10 (or the receiver terminal 20) is configured by the network device 40, the time resource of the cognitive sidelink resource of the sender terminal 10 (or the receiver terminal 20) may be configured by the terminal 30, and the terminal 30 needs to be reserved. Of course, the terminal 30 may also configure the DRX configuration for the sender terminal 10 (or the receiver terminal 20), and the network device 40 configures the time resource of the cognitive sidelink resource for the sender terminal 10 (or the receiver terminal 20), which is not limited in this embodiment of the present invention. The sender terminal 10 and the receiver terminal 20 may access different network devices, and in fig. 1, the two access to the same network device is taken as an example.

The sender terminal 10 and the receiver terminal 20, the sender terminal 10 and the terminal 30, or the receiver terminal 20 and the terminal 30 have a first interface for direct communication therebetween, and the first interface may be referred to as a PC5 interface. The transmission link over the PC5 interface for communication between terminals may be referred to as a sidelink.

For example, the PC5 interface may use a dedicated frequency band (e.g., 5.9 GHz).

As shown in fig. 4, taking the network device 40 as a base station as an example, fig. 4 shows a scenario architecture of the embodiment of the present application.

As shown in fig. 4 (a) to 4 (f), the sidelink between the sender terminal 10 and the receiver terminal 20 in fig. 4 (a) to 4 (b) may include: NR V2X SL and LTE V2X SL.

Fig. 4 (a) to fig. 4 (b) differ in that: in the architectures shown in fig. 4 (a) to 4 (b), the Core network accessed by the sender terminal 10 and the receiver terminal 20 is a 5G Core network (5G Core, 5GC), but in fig. 4 (a), the sender terminal 10 and the receiver terminal 20 access the same base station, which is an NR base station (e.g., gNB), while in fig. 4 (b), the sender terminal 10 and the receiver terminal 20 access the same base station, which is a 4G base station (e.g., eNB), and in fig. 4 (c), the sender terminal 10 and the receiver terminal 20 access the same base station, which is a 4G base station (e.g., eNB). In fig. 4 (c), the sender terminal 10 and the receiver terminal 20 access a 4G Core network (e.g., Evolved Packet Core (EPC)).

In fig. 4 (a) to 4 (c), control or configuration is provided by the base station for the NR V2X SL and LTE V2X SL of the terminal. In fig. 4 (a) to 4 (c), the transmitting terminal 10 may transmit low data volume, or emergency traffic, on LTE V2X SL. The sender terminal 10 may transmit high data volume, or high reliability demanding traffic, on the NR V2X SL.

In the architectures shown in fig. 4 (a) to fig. 4 (c), taking the case that the receiving side terminal 20 and the sending side terminal 10 access one base station as an example, in an actual process, the receiving side terminal 20 and the sending side terminal 10 may access a plurality of network devices (e.g., a main base station or a secondary base station).

The master base station may be a first base station accessed by the terminal in a random access process. The main base station is responsible for establishing control plane connection with a core network control plane entity, transmitting signaling messages and determining whether to create an auxiliary base station for the terminal. In addition, the primary base station may also select a secondary base station for the terminal. The main base station supports the access management of the signaling plane of the terminal and the distribution of the user plane.

The secondary base station may be a second base station, which is different from the main base station, and is a node for providing additional radio resources for the terminal, and there may be no direct control plane connection with the core network control plane entity. The auxiliary base station supports the shunting of the user plane of the terminal.

For example, in the embodiment of the present application, the secondary base station and the primary base station may be base stations of the same network standard. For example, the network formats corresponding to the secondary base station and the primary base station are evolved Node bs (enbs) in a 4G system. For another example, The network formats respectively corresponding to The secondary base station and The primary base station may be all The Next Generation Node B (gNB) in The NR system.

For another example, the secondary base station and the primary base station in the embodiment of the present application may be base stations of different network standards. For example, the network standard corresponding to the primary base station is eNB in the 4G system, and the network standard corresponding to the secondary base station is gNB in the NR system. Or the network standard corresponding to the primary base station is the gNB under the NR system, and the network standard corresponding to the secondary base station is the eNB under the 4G system.

As shown in (d) of fig. 4, taking the network device as an example of a base station, and taking the base stations accessed by the receiving terminal 20 and the sending terminal 10 as examples of a gNB and an eNB, where the gNB is a main base station of the receiving terminal 20 and the sending terminal 10, which may be referred to as: MgNB. The eNB is a secondary base station of the receiving terminal 20 and the transmitting terminal 10, and may be referred to as: and (7) a SeNB. The core network to which the receiver terminal 20 and the sender terminal 10 access is 5 GC.

As shown in (e) of fig. 4, taking the network device as an example of a base station, and taking the base stations accessed by the receiving terminal 20 and the sending terminal 10 as examples of a gNB and an eNB, where the eNB is a main base station of the receiving terminal 20 and the sending terminal 10, which may be referred to as: MeNB. The gNB is a secondary base station of the receiving terminal 20 and the sending terminal 10, and may be referred to as: SgNB. The core network to which the receiver terminal 20 and the sender terminal 10 access is 5 GC.

As shown in (f) of fig. 4, taking the network device as an example of a base station, and taking the base stations accessed by the receiving terminal 20 and the sending terminal 10 as examples of a gNB and an eNB, where the gNB is a main base station of the receiving terminal 20 and the sending terminal 10, which may be referred to as: MgNB. The eNB is a secondary base station of the receiving terminal 20 and the transmitting terminal 10, and may be referred to as: and (7) a SeNB. The core network accessed by the receiving terminal 20 and the sending terminal 10 is EPC.

Taking the receiving side terminal 20 and the sending side terminal 10 as an example, the receiving side terminal 20 and the sending side terminal 10 may communicate on a side uplink between the receiving side terminal 20 and the sending side terminal 10 through a resource. In the embodiment of the present application, a scenario in which the receiving-side terminal 20 and the sending-side terminal 10 communicate on the sidelink may be referred to as: in the sidelink communication scenario, as an example, resources used by the receiving terminal 20 and the sending terminal 10 for communicating on the sidelink may be referred to as: the sidelink resource, the specific name of the resource is not limited in this application embodiment, and may be set as required.

Taking the example that the sender terminal 10 sends the sidelink service data to the receiver terminal 20 by using the sidelink resource, the sender terminal 10 may currently acquire the sidelink resource in the following manner. The manner in which the receiver terminal 20 obtains the sidelink resource may refer to the manner in which the sender terminal 10 obtains the sidelink resource, and will not be described in detail later.

Mode 1(mode1), resource allocation pattern for network scheduling.

mode 1: if the sender terminal 10 performs data transmission with a network device (which may be the same network device as the network device 40 or a different network device) in a Radio Resource Control (RRC) connected state, the network device communicating with the sender terminal 10 may schedule a sidelink resource for transmitting sidelink service data for the sender terminal 10. For example, the sender terminal 10 sends a Scheduling Request (SR) and a sidelink Buffer Status Report (BSR) to the network device. The Sidelink BSR is configured to determine the size of the Sidelink communication data volume of the sender terminal 10. Based on the sidelink BSR, the network device may determine the size of the sidelink communication data volume of the sender terminal 10, and schedule, for the sender terminal 10, a sidelink resource required for transmitting the sidelink service data. The network device uses the configured side link radio network temporary identity (SL-RNTI) to schedule side link resources for Sidelink communication.

Mode 2(mode2), resource selection mode autonomously selected by the terminal.

mode2, the sender terminal 10 selects a sidelink resource from a pool of resources (typically including one or more sidelink resources). For example, the resource pool is a resource broadcasted by the network device in the system information when the sender terminal 10 is in the network coverage. The resource pool is a pre-configured resource for the sender terminal 10 when the sender terminal 10 is out of network coverage. The resource pool may be a specific resource pool for the sender terminal 10, i.e. only the sender terminal 10 may select sidelink resources in the resource pool. Or the resource pool may be a resource pool shared by a plurality of terminals including the sender terminal 10, that is, the remaining terminals except the sender terminal 10 may also select resources in the resource pool. For the latter, then, when the sender terminal 10 autonomously selects a resource in the resource pool, the sender terminal 10 may perform sensing on the resource pool to select the sidelink resource.

sidelink transmissions are based on resource pools. A resource pool is a logical concept, and a resource pool includes a plurality of physical resources, any one of which is used for transmitting data. When a terminal performs data transmission, it may use a resource from the resource pool to perform transmission.

On one hand, in this embodiment, before the sender terminal 10 sends the service data to the receiver terminal 20 on the sidelink, the sender terminal 10 may sense the sidelink resources in the sending resource pool by using the manner shown in fig. 2, and then select the sidelink resources for sending the service data to the receiver terminal 20 from the sensed sidelink resources.

On the other hand, in order to ensure the quality of sidelink resources used by sidelink service data transmitted by the sender terminal 10, when the sender terminal 10 autonomously selects sidelink resources from a transmission resource pool, resource collision caused by a plurality of terminals randomly selecting sidelink resources from the transmission resource pool is avoided, that is, the resources selected by the sender terminal 10 are prevented from being occupied by other terminals, so as to reduce communication quality. The sender terminal 10 may predict the occupation of the sidelink resource in a certain time period 1 in the future by sensing, and use the occupation of the sidelink resource in the certain time period 1 as a sensing result. The occupation of the side link resources may be: whether other terminals occupy sidelink resources in this time period 1 in the future. Therefore, based on the sensing result, the sender terminal 10 may reserve the sidelink resource corresponding to the sensing result, and ensure the communication quality of itself.

In LTE or NR based V2X communication, the sender terminal 10 may use or obtain the sensing result based on the sensing procedure defined in the LTE Release (Release) 14 standard protocol. Illustratively, the perceived result of the sidelink resource may be used to indicate any one or more of: an identity or location of a particular sidelink resource in the resource pool, a signal strength on the sidelink resource, a signal power on the sidelink resource, and a Channel Busy Ratio (CBR) of the sidelink resource.

Based on this, when the sender terminal 10 sends the service data to the receiver terminal 20, the receiver terminal 20 may perform sending on the receiving resource in the receiving resource pool (i.e. the sending resource pool), and send the receiving resource with better communication quality in the receiving resource pool as a sending result to the sender terminal 10 through the auxiliary information, so that the sender terminal 10 may consider the auxiliary information sent by the receiver terminal 20 when performing resource selection, so as to improve the data receiving quality of the sender terminal 10.

It should be noted that, the sidelink resources included in the sending resource pool and the receiving resource pool of the present application may be partially or completely the same. The sending resource pool and the receiving resource pool are relative concepts, and if the sending terminal 10 selects a sidelink resource in the resource pool 1 for sending the service data to the receiving terminal 20, the resource pool 1 is a sending resource pool for the sending terminal 10 and a receiving resource pool for the receiving terminal 20.

The terminal involved in the embodiment of the application is a device with a wireless communication function, and can be deployed on land, including indoors or outdoors, and is handheld or vehicle-mounted. And can also be deployed on the water surface (such as a ship and the like). And may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). A terminal, also referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), a terminal device, and the like, is a device for providing voice and/or data connectivity to a user. For example, the terminal includes a handheld device, a vehicle-mounted device, and the like having a wireless connection function.

In the present application, for convenience of description, a Chip disposed in the device, such as a System-On-a-Chip (SOC), a baseband Chip, or other chips having a communication function, may also be referred to as a terminal.

The terminal can be a vehicle with a corresponding communication function, or a vehicle-mounted communication device, or other embedded communication devices, or can be a user handheld communication device, including a mobile phone, a tablet computer, and the like.

A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

The transceiver 53 may be any device, such as a transceiver, for communicating with other devices or communication networks, such as an ethernet, a Radio Access Network (RAN), a Wireless Local Area Network (WLAN), etc.

Optionally, the communication device may also include a memory 52.

The memory 52 may be, but is not limited to, a read-only memory (ROM) or other type of static storage device that may store static information and instructions, a Random Access Memory (RAM) or other type of dynamic storage device that may store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disk storage, optical disk storage (including compact disc, laser disc, optical disc, digital versatile disc, blu-ray disc, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer.

The processor 51 is configured to execute computer-executable instructions stored in the memory 52, so as to implement the communication method provided by the following embodiments of the present application.

Optionally, the computer-executable instructions in the embodiments of the present application may also be referred to as application program codes, which are not specifically limited in the embodiments of the present application.

In particular implementations, processor 51 may include one or more CPUs such as CPU0 and CPU1 in fig. 5, for example, as one embodiment.

Each of these processors may be a single-core (single-CPU) processor or a multi-core (multi-CPU) processor. A processor herein may refer to one or more devices, circuits, and/or processing cores for processing data (e.g., computer program instructions).

When performing sidelink communication between current terminals, specifically considered scenarios include, but are not limited to, V2X communication, device to device (D2D), public safety (public safety), business communication (business), and other sidelink-related communication scenarios. Under the condition that the terminal does not use the DRX mechanism, the terminal continuously monitors the PSCCH in the whole time period, and the terminal continuously keeps the awakening state and can receive scheduling data sent by other terminals. In some scenarios, for example, in a unicast scenario or a multicast scenario with feedback, taking a terminal as Rx UE as an example, in order to improve quality of Rx UE receiving sidelink data, Rx UE may provide auxiliary information for sidelink resources selected by Tx UE, and the sidelink resources indicated in the auxiliary information provided by Rx UE may be in the whole time range, that is, the sensing range of Rx UE is also in the whole time period, which is very power consuming for Rx UE. Wherein, the unicast scene refers to: one Tx UE transmits traffic data to one Rx UE, but one Tx UE may simultaneously establish a sidelink connection with multiple Rx UEs. In a multicast scenario, a plurality of terminals form a group, the terminals in the group communicate with each other, and the terminals in the same group can receive all data or information in the group.

As described above, in the current sidelink communication, the Rx UE continuously detects the PSCCH or PSCCH (the PSCCH may be the PSCCH corresponding to the traffic data sent by the Tx UE, or the PSCCH detected by the Rx UE during the sending process of the reception resource pool for providing the auxiliary information), and even if there is no data sent by the Tx UE, the Rx UE does not need to receive the traffic data from the Tx UE, or the Rx UE does not need to provide the auxiliary information to the Tx UE, the Rx UE still keeps the continuous monitoring state, which consumes the power of the Rx UE very much.

Based on the above drawbacks, in the 3GPP R17, in the legislative discussion, DRX technology is introduced into sidelink to reduce the overhead of sidelink terminals. In the embodiment of the application, a DRX mechanism can be configured for Rx UE, so that the Rx UE is in an inactive period when the Rx UE does not need to receive service data, thereby avoiding invalid PSCCH monitoring and reducing the power consumption of the Rx UE.

However, when the terminal is configured with the DRX mechanism, since the terminal cannot receive the PSCCH and/or PSCCH during the inactive period, and therefore cannot sense the sidelink resources, if the time resources (e.g., the resource sensing time window shown in fig. 7 a) of the terminal used for sensing the sidelink resources and the inactive period of the terminal are all overlapped or partially overlapped (which may also be referred to as a collision), the terminal may not know whether to sense the sidelink resources or enter the inactive state at the time resources of the collision.

Therefore, the present application provides a communication method, which may notify, by a first terminal, a communication device that a first inactive period conflicts with a first time resource using first information, in a case where a DRX mechanism of the first terminal and the first time resource for sensing a sidelink resource conflict. Since the first inactive period and the first time resource conflict indicate that the sidelink resource may need to be sensed when the first terminal is in the inactive state, but actually, the first terminal cannot detect the psch-RSRP and RSSI measurement when in the inactive state, so the process of sensing the sidelink resource cannot be realized. Therefore, the communication device can adjust or cancel the DRX configuration of the first terminal and/or cancel or adjust the configuration information of the first time resource by sending the first information, so as to avoid the conflict between the sensing of the sidelink resource and the inactive period of the terminal, thereby ensuring the data transmission of the first terminal while reducing the power consumption by using the DRX configuration.

In the embodiment of the present application, a specific structure of an execution subject of one communication method is not particularly limited as long as communication can be performed by one communication method according to the embodiment of the present application by running a program in which a code of one communication method of the embodiment of the present application is recorded. For example, an execution main body of a communication method provided by the embodiment of the present application may be a functional module capable of calling a program and executing the program in the first terminal, or a communication device applied in the first terminal, such as a chip, a system-on-chip, an integrated circuit, and the like. The chip, the chip system, and the integrated circuit may be disposed inside the first terminal, or may be independent from the first terminal, which is not limited in the embodiments of the present application. An execution main body of the communication method provided in the embodiment of the present application may be a functional module capable of calling a program and executing the program in a communication device, or a communication apparatus applied in the communication device, for example, a chip system, an integrated circuit, and the like, where the chip, the chip system, and the integrated circuit may be disposed inside the communication device, or may be independent from the communication device, and the embodiment of the present application is not limited.

As shown in fig. 6, fig. 6 is a flowchart illustrating a communication method provided in an embodiment of the present application, where the method includes:

step 601, the communication device sends configuration information of the first DRX configuration and/or the first time resource to the first terminal. Accordingly, the first terminal receives configuration information of the first DRX configuration and/or the first time resource from the communication device.

Wherein the first DRX configuration includes configuration information of a first inactive period. The configuration information of the first inactive period is used to indicate that the first terminal is in an inactive state during the first inactive period. The first time resource is a time resource of the first terminal sensing sidelink resource. The communication device is a second terminal or a network device. The first time resource in the embodiments of the present application may also be referred to as a resource-aware time window.

For example, if the first terminal is the sender terminal 10 shown in fig. 3, the communication device may be the terminal 30 shown in fig. 3, or the communication device may be the network device 40 shown in fig. 3.

For example, taking the first terminal as the receiving terminal 20 shown in fig. 3 as an example, the communication device may be the terminal 30 shown in fig. 3, or the communication device may be the network device 40 shown in fig. 3.

In an aspect, the first DRX configuration includes information of the first inactive period. For example, the information of the first inactive period may be a start position and an end position of the first inactive period. For example, the information of the first inactive period may be a start position and an end duration of the first inactive period. Or the information of the first inactive period may be determined by the information of the DRX cycle and the active period, for example, the first DRX configuration includes the information of the DRX cycle and the active period. For example, the first DRX configuration includes: the DRX cycle is 10 slots (slot 1 to slot 10) and the active period is slot 1 to slot 3, the first terminal can determine that the first inactive period is 7 slots, i.e., slot 4 to slot 10. For another example, the first DRX configuration includes: the DRX cycle is 10 slots (slot 1 to slot 10), and the active periods are slot 1, slot 3, and slot 7, so the first terminal can determine that the first inactive period is 7 slots, i.e., slot 2, slot 4 to slot 6, and slot 8 to slot 10.

On the other hand, if the communication device configures the first terminal with the first inactivity period before or during the performance of step 601, or if other devices or protocols configure the first terminal with the first inactivity period, the first inactivity period is not activated. At this time, although the first terminal has the first inactive period, since the first inactive period is not activated, the action of entering the inactive state is not performed during the first inactive period. Then the configuration information of the first inactive period may be an activation indication, which indicates that the first terminal activates the first inactive period of the first terminal, and the first terminal may determine that the communication device wants the first terminal to be in an inactive state in the first inactive period after the first inactive period is activated.

Of course, in case there are multiple DRX configurations at the first terminal, the communication device sends the first DRX configuration to the first terminal, including: the communication device sends an indication 1 to the first terminal, where the indication 1 is used to indicate that the first terminal activates one DRX configuration of a plurality of DRX configurations, and then the activated DRX configuration is the first DRX configuration.

The sidelink resources in the embodiment of the present application may be used for the first terminal to send data or signaling on the sidelink. For example, the first terminal needs to perform an action of sensing the sidelink resource before sending data or signaling to the third terminal on the sidelink. At this time, the first terminal may be the sender terminal 10 shown in fig. 3.

The sidelink resources in the embodiments of the present application may be used for the first terminal to receive data or signaling on the sidelink. For example, the first terminal needs to perform an action of sensing the sidelink resource before receiving data or signaling sent by the third terminal on the sidelink. And then the first terminal sends the perceived information of the sidelink resources to the third terminal, so that the third terminal selects target sidelink resources from the sidelink resources perceived by the first terminal to be used for sending data or signaling to the first terminal. The third terminal may be the same terminal as the second terminal or different terminals, which is not limited in this embodiment of the application. This time the receiving terminal 20 shown in fig. 3.

In this embodiment, the configuration information of the first time resource may include information (e.g., an identifier, an index, or a time domain position) of the n time resources, that is, the communication device instructs the first terminal to perceive the sidelink resource on the n time resources.

In one example, the information of the n time resources is a continuous time resource. For example, the n time resources include time slots 1 to 5. The communication device configures the first terminal to sense the sidelink resources at time slots 1 through 5.

For another example, the n time resources may also be non-contiguous time resources. For example, the n time resources include slot 1, slot 3, and slot 4. The communication device configures the first terminal to sense sidelink resources at time slot 1, time slot 3, and time slot 4.

In this embodiment, the configuration information of the first time resource may include a first indication, where the first indication is used to instruct the first terminal to determine n time resources available for sensing the sidelink resource from m time resources. Wherein m is greater than or equal to n. For example, at least one bit is associated with each of the m time resources, and the at least one bit associated with any one time resource is used to indicate whether the time resource can be used as a time resource of the cognitive sidelink resource. For example, at least one bit as the first indicator indicates that the time resource can be a time resource of the cognitive sidelink resource. At least one bit is a second indicator that the time resource is not available as a time resource of the cognitive sidelink resource.

For example, taking the first indicator as 1 and the second indicator as 0 as an example, as shown in fig. 7b, the first terminal has time resources 1 to 8, at least one bit associated with time resource 1, time resource 3, time resource 4, and time resource 5 is "1", and at least one bit associated with time resource 2, time resource 5, time resource 6, time resource 7, and time resource 8 is "0". The first terminal may thus determine that the first time resources include time resource 1, time resource 3, time resource 4, and time resource 5.

For example, the m time resources may be configured for the first terminal by the communication device, and for example, the communication device further sends information of the m time resources to the first terminal when sending the configuration information of the first time resource. Or the communication device sends the information of the m time resources to the first terminal before sending the configuration information of the first time resource.

For another example, the m time resources may be predefined by a protocol or may be time resources of a cognitive sidelink resource determined by the first terminal. Whether predefined by the protocol or self-determined by the first terminal, the first terminal may report information of the m time resources to the communication device. The communication device may then determine which of the m time resources may be time resources of the cognitive sidelink resource based on the information of the m time resources.

As an example, step 601 can be divided into the following cases:

case 1), the communication device sends a first DRX configuration to the first terminal. That is, the communication device may configure the first DRX configuration for the first terminal without configuring configuration information for the first time resource.

In case 1), when the communication device does not configure the configuration information of the first time resource for the first terminal, the configuration information of the first time resource may be predefined by a protocol or determined by the first terminal itself, or configured for the first terminal by another communication device, which is not limited in this embodiment of the application.

For example, referring to fig. 3, if the communication device is a network device 40 and the first terminal is the sender terminal 10, the network device 40 may configure a first DRX configuration for the sender terminal 10.

When the first terminal accesses one base station, the network device may be a base station as shown in (a) to (c) in fig. 4, or when the first terminal is in dual connectivity, the network device may be a master base station as shown in (d) to (f) in fig. 4, or may be a secondary base station.

In an aspect, the configuration information of the first time resource may be configured by the terminal 30 for the sender terminal 10. Alternatively, on the other hand, the configuration information of the first time resource may be configured by another network device for the sender terminal 10, in conjunction with (d) to (f) in fig. 4, for example, the primary base station configures the first DRX configuration for the sender terminal 10, and the secondary base station configures the configuration information of the first time resource for the sender terminal 10. Alternatively, the secondary base station configures the first DRX configuration for the sender terminal 10, and the primary base station configures the configuration information of the first time resource for the sender terminal 10.

Case 2), the communication device sends configuration information of the first time resource to the first terminal. That is, the communication device may configure the configuration information of the first time resource for the first terminal, and not configure the configuration information of the first time resource.

In case 2), the communication device configuring the configuration information of the first time resource for the first terminal may be a different device from the device configuring the first DRX configuration for the first terminal.

For example, referring to fig. 3, the communication device is a network device 40, and the first terminal is a sender terminal 10 as an example, then the network device 40 may configure configuration information of a first time resource for the sender terminal 10, and the first DRX configuration may be configured for the sender terminal 10 by the terminal 30 or by another network device.

Referring to (d) to (f) in fig. 4, for example, taking the network device 40 as a main base station, the secondary base station configures the first DRX configuration for the sender terminal 10, and the main base station configures the configuration information of the first time resource for the sender terminal 10. Alternatively, the primary base station configures the first DRX configuration for the sender terminal 10, and the secondary base station configures the configuration information of the first time resource for the sender terminal 10.

In case 2), when the communication device does not configure the first DRX configuration for the first terminal, the first DRX configuration may be predefined by a protocol, or configured for the first terminal by another communication device, which is not limited in this embodiment of the present application.

Case 3), the communication device transmits configuration information of the first DRX configuration and the first time resource to the first terminal. In case 3), i.e. the communication device configures both the first DRX configuration and the configuration information of the first time resource for the first terminal.

In one embodiment of the present application, the communication device may actively transmit configuration information of the first DRX configuration and/or the first time resource to the first terminal.

In yet another embodiment of the present application, the communication device may then transmit the configuration information of the first DRX configuration and/or the first time resource to the first terminal based on a request of the first terminal. For example, the first terminal sends a request to the communication device requesting the communication device to configure the DRX configuration for the first terminal and/or to perceive a time period for sidelink resources. The communication device may perform step 601.

In yet another embodiment of the present application, if the communication device is the second terminal, then before step 601 may further comprise the first terminal and the second terminal establishing a sidelink over the PC5 interface. For the procedure of establishing the sidelink between the first terminal and the second terminal, reference may be made to the description in the prior art, and details are not described here. Step 601 can then be implemented as follows: the second terminal sends the first DRX configuration and/or the configuration information of the first time resource to the first terminal on the sidelink.

In another embodiment of the present application, if the communication device is a network device, then step 601 can be implemented by: the network equipment sends a first message to the first terminal by using the Uu interface. Wherein the first message includes configuration information of the first DRX configuration and/or the first time resource. For example, the first message may be an RRC message.

In a possible implementation manner, the first DRX configuration further includes configuration information of the first active period, where the configuration information of the first active period is used to indicate that the first terminal is in an inactive state in the first active period.

When the first DRX configuration and the configuration information of the first time resource are both configured for the first terminal by the communication device, the configuration information of the first DRX configuration and the configuration information of the first time resource may be carried in the same message or may be carried in different messages, which is not limited in this embodiment of the present application.

Step 602, when the first inactivity period conflicts with the first time resource, the first terminal sends the first information to the communication device, and correspondingly, the communication device receives the first information from the first terminal. Wherein the first information is used for indicating that the first inactive period conflicts with the first time resource.

For example, the first information may be carried in a second message. For example, a field 1 may be carried in the first information, where the field 1 is used to indicate that the first inactive period conflicts with the first time resource. For example, the field 1 may include at least one bit indicating that the first inactive period conflicts with the first time resource. Taking the example that field 1 includes 2 bits, then 00 is used to indicate that the first period of inactivity conflicts with the first time resource.

The conflict between the first inactive period and the first time resource in the embodiment of the present application may refer to: the first time resource and the first inactive period are all overlapped or partially overlapped. For example, as shown in fig. 7b, the first inactive period includes slot 1 to slot 3, and the first time resource includes slot 1 and slot 2, and the first time resource is located in the first inactive period, so that the first time resource and the first inactive period may be considered to collide. For example, as shown in fig. 7c, the first inactive period includes slot 1 to slot 3, and the first time resource includes slot 1, slot 2, slot 3, and slot 4, and the first inactive period is located in the first time resource, and thus may be regarded as a conflict between the first time resource and the first inactive period. For example, as shown in fig. 7d, the first inactive period includes time slot 1 to time slot 3, and the first time resource includes time slot 1, time slot 2, and time slot 3, and the time resource corresponding to the first inactive period is the same as the first time resource, so that the first time resource and the first inactive period may also be regarded as conflicting.

In an embodiment of the present application, the communication device may determine to adjust or cancel the DRX configuration configured for the first terminal after receiving the first information, and/or the communication device may determine to adjust or cancel the configuration information of the first time resource configured for the first terminal after receiving the first information.

The embodiment of the present application provides a communication method, which may be configured to notify, by a first terminal, a communication device that a first inactive period conflicts with a first time resource by using first information, when a DRX mechanism of the first terminal and the first time resource for sensing a sidelink resource conflict. Since the first inactive period and the first time resource conflict indicate that the sidelink resource may need to be sensed when the first terminal is in the inactive state, but actually, the first terminal cannot detect the psch-RSRP and RSSI measurement when in the inactive state, so the process of sensing the sidelink resource cannot be realized. Therefore, the first terminal sends the first information to the communication device, so that the communication device can adjust or cancel the DRX configuration of the first terminal in time, and/or cancel or adjust the configuration information of the first time resource, thereby avoiding the conflict between the sensing sidelink resource and the inactive period of the first terminal, and ensuring the data transmission of the first terminal while reducing the power consumption by adopting the DRX configuration.

The method provided by the embodiment of the application can be suitable for unicast, multicast and broadcast scenes.

Optionally, the second message may be RRC, a Media Access Control (MAC) Control Element (CE), and Sidelink Control Information (SCI).

Since there is a difference in the way the first terminal handles in case of a conflict between the first time resource and the first inactivity period, the following will be introduced separately:

example 1, a communication device configures a first DRX configuration for a first terminal.

Example 1-1, the period of inactivity of the first terminal needs to be adjusted.

In one embodiment of the application, the first information is further used to indicate that the inactivity period of the first terminal is adjusted.

The inactive period of the first terminal is a general concept, i.e. the first information is used to adjust other active periods of the first terminal in addition to the first inactive period of the first terminal. Or the inactivity period of the first terminal is a special concept, i.e. the first inactivity period of the first terminal is adjusted.

For example, field 1 is also used to indicate that the inactivity period of the first terminal is adjusted. For example, field 1 includes a first bit and a second bit. Wherein the first bit is used to indicate that the first period of inactivity conflicts with the first time resource. The second bit indicates to adjust the inactivity period of the first terminal.

For another example, the first information further includes a field 2, where the field 2 is used to indicate that the inactivity period of the first terminal is adjusted.

In another embodiment of the present application, as shown in fig. 8, the method provided in the embodiment of the present application includes steps 801 to 802, and steps 803 to 808, where steps 801 to 802 synchronize steps 601 to 602, and are not described herein again.

Step 803, the first terminal sends the second information to the communication device. Accordingly, the communication device receives the second information from the first terminal. Wherein the second information is used for indicating to adjust the inactive period of the first terminal.

Illustratively, the second information carries a field 3, where the field 3 is used to indicate that the inactivity period of the first terminal is adjusted. For example, the field 3 may include at least one bit indicating that the inactivity period of the first terminal is adjusted. Taking the example that field 3 comprises 2 bits, then 01 is used to indicate that the inactivity period of the first terminal is adjusted.

In one embodiment of the present application, the first information and the second information may be carried in the same message, such as the second message. This may save signalling overhead between the first terminal and the communication device.

In another embodiment of the present application, the first information and the second information may be carried in different messages.

In one embodiment of the present application, step 802 and step 803 are not performed in a sequential order.

It can be understood that, in a case that the communication device receives a command for adjusting the inactive period of the first terminal, the communication device may select to adjust the inactive period of the first terminal, or may select not to adjust the inactive period of the first terminal, which may be based on an implementation of the communication device, and this is not limited in this embodiment of the present application. If the communication device decides to adjust, the communication device may perform the step of, if the communication device chooses not to adjust, the communication device may send a not adjustment indication to the first terminal so that the first terminal determines that the communication device does not agree to adjust the inactive period of the first terminal.

Since the communication device may choose to adjust the inactive period of the first terminal after receiving the first information, if the communication device does not know the information of the first time resource, the inactive period reconfigured for the first terminal may still overlap with the first time resource, and to avoid this problem, as shown in fig. 8, in an embodiment of the present application, the method provided in this embodiment of the present application may further include:

and step 804, the first terminal sends third information to the communication equipment. Accordingly, the communication device receives the third information from the first terminal. The third information is information indicating a second inactive period. The second inactive period is an inactive period desired by the first terminal.

As a possible embodiment, the time resource corresponding to the second inactive period does not conflict with the first time resource, which can be said to be: and the time resource corresponding to the second inactive period does not have intersection with the first time resource.

In one example, the third information and the second information may be carried in the same message. This saves signalling overhead between the first terminal and the communication device.

For another example, the third information and the second information are carried in different messages.

As another example, the third information and the second information are the same information, for example, the second information has both a function of instructing the communication device to adjust an inactive period of the first terminal and a function of instructing the communication device to adjust an inactive period of the second terminal. For example, the second information has a field a indicating that the communication device adjusts the inactive period of the first terminal, and information indicating the second inactive period.

For example, the third information may be a field in the second information, or the second information may be a field in the third information.

The information for indicating the second inactive period may include: the third information is information of the second inactive period or the third information is an offset value, which facilitates the communication device to determine the information of the second inactive period according to the information of the first inactive period and the offset value. For example, the offset value is 1 slot, and if the first inactive period is slot 1 and slot 2, the communication device may determine that the second inactive period is slot 2 and slot 3.

It is worth mentioning that the first terminal may also implicitly instruct the communication device to adjust the period of inactivity of the first terminal. For example, if step 804 is performed but step 803 is not performed, the first terminal may determine that the inactivity period of the first terminal needs to be adjusted if the third information is received.

In an embodiment of the present application, before step 804, the method provided in the embodiment of the present application may further include: and the first terminal determines the information of the second inactive period of the first terminal according to the configuration information of the first time resource.

For example, one DRX cycle includes 10 time resources, and the first terminal has DRX cycle 1 and DRX cycle 2. For example, time resource 1 through time resource 10. The time resources 1 to 3 in any DRX cycle are time resources corresponding to a first inactive period of the first terminal. The time resource 4 to the time resource 10 are time resources corresponding to the inactive period of the first terminal. If the first time resource of the first terminal is the time resource 8-10 in the DRX cycle 1, the first terminal may determine that the time resource corresponding to the second inactive period is the time resource 1-7, that is, the subsequent first terminal is in an inactive state in the time resource 1-7 in each DRX cycle, and is in an active state in the time resource 8-10 in each DRX cycle.

Step 805, the first terminal maintains the wake-up state during the first inactive period.

In one embodiment of the present application, after the first terminal sends the third information to the communication device, regardless of whether the communication device instructs to adjust the inactivity period of the first terminal, the first terminal maintains the awake state when the first inactivity period arrives, that is, the first terminal does not enter the inactive state during the first inactivity period.

In an embodiment of the present application, after the first terminal sends the third information to the communication device, the first terminal maintains the awake state when the first inactive period arrives, if the first terminal receives the condition that the communication device allows the adjustment of the inactive period of the first terminal.

It should be noted that, in the embodiment of the present application, after the first terminal performs step 801 and step 802, step 803 to step 804 may not be performed, but step 805 is performed. That is, after the first terminal indicates the communication device that there is a collision, the first terminal does not perform an action of entering the inactive state when the first inactive period arrives.

In one embodiment of the present application, step 805 in the embodiment of the present application may be implemented by: the first terminal maintains the awake state on the time resource where the first inactive period and the first time resource conflict, i.e., does not enter the inactive state, and enters the inactive state on the time resource where the first inactive period and the first time resource do not conflict.

For example, if the first inactive period includes time resource 1 to time resource 5, and the first time resource includes time resource 2 to time resource 4, the first terminal may enter the inactive state on time resource 1 and time resource 5, and maintain the awake state on time slot resource 2 to time 4. Therefore, the purpose of reducing power consumption of the first terminal can be achieved, and the purpose of sensing side uplink resources can also be achieved.

In an embodiment of the present application, as shown in fig. 8, a method provided in an embodiment of the present application further includes:

step 806, the first terminal enters an inactive state during the second inactive period.

Optionally, the second inactive period and the first time resource do not conflict. For example, the first time resource is time resource 1 to time resource 4, and the time resource corresponding to the second inactive period may be time resource 5 to time resource 8. For example, the first time resource is time resource 1, time resource 4, and time resource 5, and the time resources corresponding to the second inactive period may be time resource 2 to time resource 3.

In one embodiment of the application, the first terminal enters the inactive state when the second inactive period arrives, regardless of whether the communication device instructs to adjust the inactive period of the first terminal.

In one embodiment of the application, the first terminal enters the inactive state when the second inactive period arrives, in case it receives that the communication device allows to adjust the inactive period of the first terminal. This ensures that the state of the first terminal known by the communication device side matches the actual state of the first terminal.

In an embodiment of the present application, as shown in fig. 8, a method provided in an embodiment of the present application further includes, after step 802:

step 807, the communication device sends the second DRX configuration or the first indication to the first terminal, and accordingly, the first terminal receives the second DRX configuration or the first indication from the communication device.

Wherein the first indication is used for indicating that the first DRX configuration configured for the first terminal is cancelled or invalid. The second DRX configuration is used to determine a third inactive period of the first terminal, the third inactive period being derived from the first inactive period and the first offset value. For example, the second DRX configuration may include information of the third inactive period or the second DRX configuration may include the first offset value, which is not limited in this embodiment.

In an embodiment of the present application, the method provided by the embodiment of the present application may further include, before step 807: the communication device determines a third period of inactivity. If the communication device receives the information of the second inactive period, the communication device may refer to the information of the second inactive period to determine a third inactive period. For example, the time resource corresponding to the third inactive period is the time resource corresponding to the second inactive period, or the time resource corresponding to the third inactive period is located in the time resource corresponding to the second inactive period. Or the time resource corresponding to the third inactive period includes a time resource corresponding to the second inactive period, which is not limited in this embodiment of the application. This may allow the third inactivity period that the communication device reconfigures for the first terminal to not conflict with the first time resources of the first terminal. If the communication device does not receive the information of the second inactive period, the third inactive period may be determined by the communication device according to its implementation, which is not limited in this embodiment. If the communication device is able to determine the information of the first time resource, the communication device may determine the information of the third inactive period according to the information of the first time resource, where the third inactive period configured for the first terminal by the communication device does not conflict with the first time resource.

And 808, the first terminal enters an inactive state in a third inactive period.

It should be noted that, in the case where the first terminal receives the fourth information, the first terminal does not execute step 806. In case the first terminal does not receive the fourth information, the first terminal performs step 806.

It is noted that, in example 1-1, even if the first terminal indicates that the communication device needs to adjust the inactivity period of the first terminal, if the communication device determines that the first inactivity period conflicts with the first time resource according to the first information, the communication device may perform step 807, that is, the above-mentioned steps 803 to 806 may be omitted. Steps 801 to 802, 807 and 808 may be taken as an embodiment to describe a scheme of how the communication device handles in a case where the first terminal informs the communication device that there is a collision.

In example 1-1, the first terminal may indicate to the communication device that the first inactivity period conflicts with the first time resource using the first information regardless of whether the communication device configures the first terminal with information of the first time resource. Further, in example 1, the first terminal instructs the communication device to cancel or adjust the first period of inactivity when the first period of inactivity and the first time resource conflict.

It is worth noting that in example 1-1, the first terminal is aware of the sidelink resource on the first time resource.

In this embodiment of the application, when the first terminal determines that the first time resource and the first inactive period conflict, if the first terminal needs to send data or signaling to another terminal on the sidelink resource, or the first terminal needs to receive data or signaling sent by another terminal on the sidelink resource, the first terminal may decide to adjust the inactive period of the first terminal or notify the communication device to adjust the inactive period of the first terminal, and sense the sidelink resource on the first time resource. Therefore, the power consumption of the first terminal can be saved, and the transmission quality of the data of the first terminal can be ensured.

Examples 1-2, the inactive period of the first terminal needs to be cancelled.

In another embodiment of the present application, as shown in fig. 9, the method provided in the embodiment of the present application includes steps 901 to 902 and step 903, where steps 601 to 602 are synchronized in steps 901 to 902, and are not described herein again.

Step 903, the first terminal sends fourth information to the communication device, and correspondingly, the communication device receives the fourth information from the first terminal. The fourth information is for indicating that the first DRX configuration to be configured for the first terminal is cancelled or invalid.

For example, the fourth information may be the same information as the first information, e.g., the first information is used to indicate both the first inactivity period and the first time resource conflict, and to indicate that the first DRX configuration configured for the first terminal is cancelled or disabled.

For another example, the fourth information and the first information are different information, and both of them may be carried in the same message or different messages.

Step 904, the first terminal maintains the awake state during the first inactive period.

In an embodiment of the application, after the first terminal sends the third information to the communication device, the first terminal maintains the awake state after the first inactive period arrives when the first terminal receives the condition that the communication device allows the adjustment of the inactive period of the first terminal.

It should be noted that, in the embodiment of the present application, after the first terminal performs step 901 and step 902, step 903 may not be performed, but step 904 is performed. That is, after the first terminal indicates the communication device that there is a collision, the first terminal does not perform an action of entering the inactive state when the first inactive period arrives.

Step 905 and synchronization step 807 are not described herein again.

It should be noted that, in a case that the first terminal instructs to cancel the first DRX configuration, the communication device may perform an operation of canceling the first DRX configuration, and of course, the communication device may also perform an operation of adjusting the first DRX configuration, which is not limited in this embodiment of the present application.

In this embodiment of the application, when the first terminal determines that the first time resource and the first inactive period conflict, if the first terminal needs to send data or signaling to another terminal on the sidelink resource, or the first terminal needs to receive data or signaling sent by another terminal on the sidelink resource, the first terminal may decide to cancel the first inactive period, and sense the sidelink resource on the first time resource. Thus, although it is not guaranteed that the power consumption of the first terminal is saved, the transmission quality of the data of the first terminal can be guaranteed.

Example 2, the communication device configures at least configuration information of a first time resource for the first terminal.

It is worth noting that in example 2, the communication device may also configure the first DRX configuration for the first terminal, except that the first terminal instructs the communication device to cancel or adjust the configuration information of the first time resource when the first inactive period and the first time resource conflict. The following will be separately introduced:

example 2-1), configuration information that requires cancellation of the first time resource.

In an aspect, the first information is further used to indicate configuration information for canceling the first time resource. For example, the first information includes field 1, where field 1 is used to indicate that the first time resource and the first inactivity period conflict, and is used to indicate configuration information for canceling the first time resource. For another example, the first information includes a field 1 and a field 4, where the field 1 is used to indicate that the first time resource conflicts with the first inactivity period. The field 4 is used to indicate configuration information for canceling the first time resource.

On the other hand, as another embodiment of the present application, as shown in fig. 10, there is provided a communication method according to an embodiment of the present application, including: step 1001 to step 1002, wherein step 1001 to step 1002 are the same as the description of step 601 to step 602, and are not described herein again.

In an embodiment of the present application, as shown in fig. 10, a method provided in an embodiment of the present application may further include:

step 1003, the first terminal sends the fifth information to the communication device, and correspondingly, the communication device receives the fifth information from the first terminal. And the fifth information is used for indicating the configuration information of canceling the first time resource.

The configuration information for canceling the first time resource in the embodiment of the present application may also be referred to as configuration information for invalidating the first time resource, that is, the configuration information for not adopting the first time resource by the first terminal.

The fifth information and the first information in the embodiment of the application may be carried in the same message, or may be carried in different messages. The fifth information may be a field in the first information, or the first information may be a field in the fifth information.

Optionally, after step 1003, the communication device may send an indication to the first terminal to indicate that the first terminal is allowed to cancel the configuration information of the first time resource. Or after step 1003, the communication device reconfigures the time resource for sensing the sidelink resource for the first terminal, which is not limited in this embodiment of the application.

and 1004, the first terminal does not execute the action of sensing the sidelink resource on the time resource conflicted with the first inactive period.

It is worth noting that since the first time resource may partially overlap with the first inactive period, the first terminal does not perform the action of sensing the sidelink resource at the partially overlapping time resource. For example, taking time resources as slots, the first time resource includes slot 1 to slot 4 as an example, where slot 1 to slot 3 are located in a first inactive period (e.g., an inactive period within DRX cycle 1 shown in (c) of fig. 7), then the first terminal may sense the sidelink resource on slot 4, but does not perform the action of sensing the sidelink resource on slot 1 to slot 3. The timeslots 1 to 4 may be continuous or discontinuous, and fig. 7 (c) illustrates an example in which the timeslots 1 to 4 are continuous time resources, which is not limited in this embodiment.

Alternatively, step 1004 in the embodiment of the present application may be replaced by: the first terminal does not perform the action of sensing the sidelink resource on the first time resource. In combination with the above example, the first terminal does not perceive sidelink resources on time resource 1 to time resource 3.

In this embodiment, after the first terminal sends the first information, step 1003 may not be executed, but step 1004 is executed, that is, the first terminal indicates that the first inactivity period of the communication device and the first time resource conflict with each other, and then step 1004 is executed. Alternatively, the first terminal executes step 1003 and step 1004 after transmitting the first information. This has the advantage that the fifth information informs the communication device that the first terminal needs to cancel the configuration information of the first time resource, so that the communication device can clarify the subsequent processing of the first terminal.

In one embodiment of the present application, if the first terminal receives an indication that the communication device allows canceling the configuration information of the first time resource before step 1004, the first terminal performs step 1004 again. This may avoid that the first terminal does not become aware of the sidelink resource on a conflicting time resource without being allowed by the communication device.

In this embodiment of the application, when the first terminal determines that the first time resource and the first inactive period conflict, if the first terminal determines that there is no data or signaling sent to another terminal on the sidelink resource, or the first terminal does not receive the data or signaling sent by another terminal on the sidelink resource, the first terminal may decide to cancel or notify the communication device to cancel the configuration information of the first time resource, and enter the inactive state in the first inactive period. This may ensure power consumption of the first terminal.

In example 2-1), the first terminal enters an inactive state during a first inactive period.

Example 2-2, configuration information for a first time resource needs to be adjusted.

In one example, the first information is further used to adjust configuration information for the first time resource. For example, the first information includes field 1, where field 1 is used to indicate that the first time resource and the first inactivity period conflict, and is used to indicate configuration information for adjusting the first time resource. For another example, the first information includes field 1 and field 5, where field 1 is used to indicate that the first time resource conflicts with the first inactivity period. The field 5 is used to indicate configuration information for adjusting the first time resource.

On the other hand, as another embodiment of the present application, as shown in fig. 11, there is provided a communication method according to an embodiment of the present application, the method including: step 1101 to step 1102, wherein step 1101 to step 1102 are the same as the description of step 601 to step 602, and are not described herein again.

In an embodiment of the present application, as shown in fig. 11, a method provided in an embodiment of the present application may further include:

step 1103, the first terminal sends the sixth information to the communication device. Accordingly, the communication device receives the sixth information from the first terminal. The sixth information is used for indicating configuration information for adjusting the first time resource.

The sixth information and the first information in the embodiment of the present application may be carried in the same message, or may be carried in different messages. The sixth information may be a field in the first information, or the first information may be a field in the sixth information. The embodiment of the present application does not limit this.

in step 1104, the first terminal sends information indicating the first time period to the communication device, and correspondingly, the communication device receives the information indicating the first time period from the first terminal. Wherein a first time period is not in conflict with the first inactive period, and the first time period is a time period of sensing sidelink resources desired by the first terminal.

The communication device is facilitated by performing step 1104 to determine a time period of a perceived sidelink resource desired by the first terminal, and the communication device is caused to re-determine the first time period as a reference for the time resource used by the first terminal for the perceived sidelink resource in case it is determined that the first time resource conflicts with the first inactivity period.

It should be noted that the above step 1103 may be omitted, that is, the first terminal determines that the first time resource and the first inactive period conflict, and then does not send the sixth information, but performs step 1104 to send information indicating the first time period, so as to implicitly instruct the communication device to adjust the configuration information of the first time resource. In this case, the information indicating the first period may be carried in the same message as the first information.

The information for indicating the first time period in the embodiment of the present application may be the first time period, and the first time period may be a continuous time period or a discontinuous time period.

The information for indicating the first time period in the embodiment of the present application may be an offset value, which facilitates the communication device to determine the first time period according to the first time resource and the offset value.

step 1105, the first terminal perceives the sidelink resource in the first time period.

In an alternative implementation, after the first terminal sends the information indicating the first time period to the communication device, the first terminal performs step 1105 regardless of whether the communication device reconfigures the time resource for the first terminal for perceiving the sidelink resource or whether the first terminal is allowed to adopt the first time period.

In another alternative implementation, after the first terminal sends the information indicating the first time period to the communication device, and the first terminal is allowed to use the first time period by the obtained communication device, the first terminal performs step 1105.

In this embodiment of the application, when the first terminal determines that the first time resource and the first inactive period conflict, if the first terminal determines that data or signaling is sent to another terminal on the sidelink resource, or the first terminal needs to receive the data or signaling sent by another terminal on the sidelink resource, the first terminal may decide to adjust or notify the communication device to adjust the configuration information of the first time resource, and enter an inactive state in the first inactive period. Therefore, the power consumption of the first terminal can be reduced, and the communication quality of the first terminal is improved.

Example 3), the configuration information of the first DRX configuration and the first time resource are each configured by the communication device for the first terminal.

In example 3, in an aspect, the first information is further used to indicate configuration information for adjusting the first time resource, and to adjust an inactivity period of the first terminal.

As above, for example, the first information includes field 1, where field 1 is used to indicate that the first time resource and the first inactive period conflict, and to indicate configuration information adjusted to the first time resource, and to adjust the inactive period of the first terminal.

For another example, the first information includes field 1 and field 6. Wherein field 1 is used to indicate that the first time resource and the first inactivity period conflict. The field 6 is used to indicate configuration information of the first time resource and to adjust the period of inactivity of the first terminal.

For another example, the first information includes field 1, field 7, and field 8. Wherein field 1 is used to indicate that the first time resource and the first inactivity period conflict. The field 7 is used to indicate configuration information of the first time resource. The field 8 is used to indicate that the inactivity period of the first terminal is adjusted.

On the other hand, as another embodiment of the present application, as shown in fig. 12, there is provided a communication method according to an embodiment of the present application, including: step 1201 to step 1202.

Step 1201, the communication device configures configuration information of a first time resource and a first DRX configuration for the first terminal.

Step 1202 is the same as the above description of step 602, and is not repeated here.

In a possible embodiment, as shown in fig. 12, the method provided in the embodiment of the present application may further include:

step 1203, the first terminal sends the seventh information to the communication device, and correspondingly, the communication device receives the seventh information from the first terminal. The seventh information is used for indicating configuration information for adjusting the first time resource and adjusting an inactive period of the first terminal.

For example, the seventh information and the first information may be carried in the same message or carried in different messages, which is not limited in this embodiment of the application. For example, the seventh information includes a field 6. Or the seventh information includes a field 7 and a field 8.

In an embodiment of the present application, as shown in fig. 12, a method provided in an embodiment of the present application may further include:

step 1204, the first terminal does not perform the action of sensing the sidelink resource on the time resource where the first time resource and the first inactive period conflict, and maintains the wake-up state in the first inactive period.

It should be noted that the step 1203 may be omitted, that is, the first terminal determines that the first time resource and the first inactivity period conflict, and then does not send the seventh information, and performs the step 1204. This has the advantage that the first terminal and the communication device may negotiate in advance or the protocol predefines that there is a conflict resolution, i.e. the first terminal does not perform the action of sensing sidelink resources on the conflicting time resources and maintains the awake state during the first inactive period.

In one embodiment of the present application, if the first terminal receives an indication of permission of the communication device before step 1204, the first terminal performs step 1204 again. This may avoid that the first terminal is not allowed by the communication device, does not perceive the sidelink resource on a conflicting time resource and does not enter the inactive state according to the configuration of the first DRX.

In one embodiment of the present application, after the first terminal sends the first information to the communication device, the first terminal performs step 1204 regardless of whether the first terminal receives an indication of permission from the communication device. This is because, due to the conflict, the first terminal cannot determine whether to enter the non-sleep state or the aware of the sidelink resource at the conflicting time resource, and therefore the first terminal may not perform the act of aware of the sidelink resource and maintain the awake state during the first inactive period.

In an embodiment of the present application, as shown in fig. 12, a method provided in an embodiment of the present application further includes:

step 1205, the first terminal sends, to the communication device, information indicating a second time period and information indicating a third time period, where the second time period and the third time period are not overlapped, the second time period is a time period that is desired by the first terminal and used for sensing sidelink resources, and the third time period is a time period that is desired by the first terminal and is in an inactive state.

By performing step 1205, the communication device may determine the time period in which the first terminal desires to perceive the sidelink resource and the time period in which the first terminal desires to be in the inactive state, so that the communication device may refer to the information of the second time period when subsequently reconfiguring the time period for perceiving the sidelink resource for the first terminal, and may also refer to the third time period when configuring the inactive period for the first terminal.

step 1206, the communications device sends configuration information of the second time resource and/or a second DRX configuration to the first terminal, and correspondingly, the first terminal receives the configuration information of the second time resource and/or the second DRX configuration from the communications device.

Reference may be made to the above description for the configuration information of the second time resource and the function of the second DRX configuration, which is not limited in this embodiment of the present application.

It is worth mentioning that, in case that both the first DRX configuration and the configuration information of the first time resource are configured for the first terminal by the communication device, the communication device may select to reconfigure the time resource for sensing the sidelink resource and the inactive period for the first terminal at the same time. The communication device may also reconfigure, for the first terminal, a time resource for sensing a sidelink resource, or reconfigure an inactive period of the first terminal, which is not limited in this embodiment of the present application.

In an embodiment of the present application, a method provided in an embodiment of the present application further includes: the first terminal receives seventh information from the communication device, the seventh information being used for indicating to cancel or invalidate the first DRX configuration and being used for indicating to cancel or invalidate configuration information of the first time resource. Thus, in the event of a conflict, the communications device allows the first terminal to not enter an inactive state for a first period of inactivity and not to perceive sidelink resources on first time resources.

The above-mentioned scheme of the embodiment of the present application is introduced mainly from the perspective of interaction between network elements. It will be appreciated that various network elements, such as the first terminal, the communication device, etc., for implementing the above-described functions, include corresponding structures and/or software modules for performing the respective functions. Those of skill in the art would readily appreciate that the various illustrative elements and algorithm steps described in connection with the embodiments disclosed herein may be implemented as hardware or combinations of hardware and computer software.

Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

In the embodiment of the present application, the first terminal and the communication device may perform the division of the functional units according to the method, for example, each functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing unit. The integrated unit can be realized in a form of hardware, and can also be realized in a form of a software functional unit.
