In order to save power consumption during direct communication between User Equipment (UE), sidelink Discontinuous Reception (DRX) is introduced, and the sending UE sends sidelink data only within an active time of receiving the UE, thereby avoiding data loss.

If UE a is in cell 1 supporting sidelink DRX and UE B is in cell 2 not supporting sidelink DRX, UE a may not receive sidelink broadcast and multicast data sent by UE B if only sidelink DRX active time for broadcast and multicast is used for sidelink reception.

In order to solve the above problem, the present disclosure provides a control method and apparatus for directly connecting sidelink to DRX in a discontinuous reception mode.

Fig. 2 is a flowchart illustrating a control method for DRX direct-connected sidelink discontinuous reception according to an embodiment of the present disclosure, and it should be noted that the control method for DRX direct-connected sidelink discontinuous reception according to the embodiment of the present disclosure may be applied to a UE sending user equipment.

Step 201, when a cell which does not support sidelink DRX is detected, a first indication is sent to other UEs.

Wherein the first indication is used for indicating that the cell does not support sidelink DRX.

In the embodiment of the present disclosure, a sending UE determines whether a cell supports sidelink DRX according to whether the cell carries a sidelink DRX parameter for multicast and broadcast in system information (SIB12), and sends a first indication to other UEs in response to not carrying the sidelink DRX parameter for multicast and broadcast.

As a possible implementation, the other UEs are receiving UEs other than the sending UE itself.

The receiving UE and/or other UEs may refer to devices that provide voice and/or data connectivity to users, handheld devices with wireless connection capability, or other processing devices connected to wireless modems or the like. In different systems, the name of the receiving UE and/or other UEs may also be different, for example in a 5G system, the wireless UE may communicate with one or more CNs (Core networks) via a RAN, and the wireless first UE may be a mobile UE, such as a mobile telephone (or so-called "cellular" telephone) and a computer having a mobile UE, for example, a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, which exchange language and/or data with a radio access Network.

For example, the receiving UE and/or other UEs may be PCS (Personal Communication Service) phones, cordless phones, SIP (Session Initiated Protocol) phones, WLL (Wireless Local Loop) stations, PDAs (Personal Digital assistants), and other devices.

In summary, in the technical solution, when the sending UE detects a cell that does not support sidelink DRX, the sending UE sends a first indication to another UE, where the first indication is used to indicate that the cell does not support sidelink DRX, so that the receiving UE does not start sidelink DRX according to the first indication, so that the receiving UE continuously monitors sidelink communication in response to the first indication, and does not start sidelink DRX, which may avoid that the UE cannot receive sidelink data of another UE under the control of the cell that does not support sidelink DRX.

Fig. 4 is a flowchart of another control method for DRX directly connected to a sidelink according to an embodiment of the present disclosure, where the control method for DRX directly connected to a sidelink according to the present disclosure may be applied to a sending UE, and the control method for DRX directly connected to a sidelink according to an embodiment of the present disclosure may be executed alone, or may be executed in combination with any one of the embodiments or possible implementation manners in the embodiments of the present disclosure, or may be executed in combination with any one of technical solutions in related technologies.

As shown in fig. 3, the method for controlling DRX direct-connected sidelink discontinuous reception may include the following steps:

As shown in fig. 4, the method for controlling the direct sidelink DRX discontinuous reception may include the following steps:

step 401, detecting whether there is a cell not supporting sidelink DRX.

In the embodiment of the present disclosure, the sending UE determines whether the cell supports sidelink DRX according to whether the cell carries a sidelink DRX parameter for multicast and broadcast in system information (SIB 12).

Step 402, when a cell not supporting sidelink DRX is detected, responding to the transmitting UE satisfying the first condition.

In the embodiment of the disclosure, the sending UE determines whether the cell supports sidelink DRX according to whether the cell carries sidelink DRX parameters for multicast and broadcast in system information (SIB12), and sends a first indication to other UEs in response to not carrying the sidelink DRX parameters for multicast and broadcast.

In order to reduce the loss of the cell processing resources, step 403 is executed continuously in response to that the sending UE satisfies the first condition, and in response to that the sending UE does not satisfy the first condition, the sending of the first indication to other UEs is omitted this time, so as to save unnecessary loss of the cell processing resources.

Step 403, in response to the first condition being met, sending a first indication to other UEs.

The other UE (or receiving UE) does not start the sidelink DRX according to the first indication so that the receiving UE continuously monitors the sidelink communication in response to the first indication and does not start the sidelink DRX, thereby avoiding the condition that the UE cannot receive the broadcast and multicast data of the other UE under the control of the cell which does not support the sidelink DRX

In summary, in the technical solution, the sending UE detects whether there is a cell that does not support sidelinkDRX; when a cell which does not support sidelink DRX is detected, whether the sending UE meets a first condition is continuously determined, and in response to the first condition being met, a first instruction is continuously sent to other UEs, so that the receiving UE does not start the sidelink DRX according to the first instruction, so that the receiving UE continuously monitors sidelink communication in response to the first instruction, and does not start the sidelink DRX, thereby avoiding that the UE cannot receive sidelink data of other UEs which are under the control of the cell which does not support the sidelink DRX, and further saving unnecessary loss of cell processing resources.

step 501, detecting whether a cell which does not support sidelink DRX exists.

Step 502, when detecting a cell not supporting sidelink DRX, responding to that the sending UE satisfies the first condition, where the first condition is that a channel measurement result between the sending UE and a serving cell to which the sending UE belongs is smaller than a first threshold.

As a possible implementation manner, the first condition is that a result of channel measurement between the sending UE and the serving cell is smaller than a first threshold. In the embodiment of the present disclosure, the radio channel measurement may represent signal received power, where in different communication systems, received power corresponding to at least one radio channel measurement of a transmitting UE is also different.

As a possible implementation manner, the wireless channel measurement result is Reference Signal Receiving Power (RSRP).

Step 503, in response to the first condition being met, sending a first indication to the other UEs.

In summary, in the technical solution, the sending UE detects whether there is a cell that does not support sidelinkDRX; when a cell which does not support sidelink DRX is detected, whether a sending UE meets a first condition is continuously determined, in response to the first condition being met, the first condition is that a channel measurement result between the sending UE and a serving cell to which the sending UE belongs is smaller than a first threshold value, a first instruction is continuously sent to other UEs, so that the receiving UE does not start sidelink DRX according to the first instruction, the receiving UE continuously monitors sidelink communication in response to the first instruction, and the sidelink DRX is not started, the UE can be prevented from not receiving broadcast and multicast data of other UEs which are under the control of the cell which does not support sidelink DRX, and in addition, unnecessary loss of cell processing resources can be saved.
