Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a control method and apparatus for direct sidelink discontinuous reception of DRX. Background Technology

[0002] To save power consumption during direct communication between User Equipment (UE) and UE, Discontinuous Reception (DRX) is introduced. The receiving UE only receives sidelink data during its active period, and the transmitting UE only transmits sidelink data during the receiving UE's active period.

[0003] If UE A is in cell 1 that supports sidelink DRX, while UE B is in cell 2 that does not support sidelink DRX, then UE B may send sidelink data outside of UE A's activation time. If UE A only performs sidelink reception during the sidelink DRX activation time, it may not be able to receive the sidelink data sent by UE B. Summary of the Invention

[0004] The first aspect of this disclosure provides a control method for direct sidelink discontinuous reception of DRX, applied to a transmitting user equipment (UE), the method comprising: when a cell that does not support sidelink DRX is detected, sending a first indication to other UEs.

[0005] In this technical solution, when the transmitting UE detects a cell that does not support sidelink DRX, it sends a first indication to other UEs so that the receiving UEs respond to the first indication by continuously listening to sidelink communication and not starting sidelink DRX. This can prevent the UE from being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX.

[0006] Optionally, the first indication includes at least one of the following: the identifier of the cell; and the frequency at which the cell is located.

[0007] Optionally, the method further includes: in response to the transmitting UE satisfying the first condition, performing the sending of the first indication to other UEs; the first condition being that the channel measurement result between the transmitting UE and its serving cell is less than a first threshold value.

[0008] Optionally, the method further includes: in response to the cell satisfying at least one of the following, performing the first instruction to send to other UEs; the cell is the serving cell to which the sending UE belongs; the cell is at a sidelink operating frequency; the cell supports sidelink functionality; and the cell does not carry sidelink transmission resources in its system information.

[0009] Optionally, the sidelink operating frequency includes: determined according to pre-configuration or higher-level configuration.

[0010] Optionally, the support for sidelink functionality includes: responding to the sidelink system information determination.

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. In response to the first indication, the receiving UE continues to listen for sidelink communication and does not start sidelink DRX, which can prevent the UE from being unable to receive broadcast and multicast data from other UEs under the control of cells that do not support sidelink DRX.

[0015] Optionally, the first indication includes at least one of the following: the identifier of the cell; and the frequency at which the cell is located.

[0017] Optionally, in response to the first indication carrying the identifier of the cell, it is determined whether the serving cell to which the receiving UE belongs is a neighboring cell of the cell corresponding to the identifier of the cell; if the serving cell to which the receiving UE belongs is a neighboring cell of the cell corresponding to the identifier of the cell, the continuous listening sidelink communication is performed in the neighboring cell of the cell, and sidelinkDRX is not started.

[0018] Optionally, determining whether the serving cell to which the receiving UE belongs is a neighboring cell of the cell in response to the first indication carrying the identifier of the cell includes: determining whether the serving cell to which the receiving UE belongs is a neighboring cell of the cell based on the neighboring cell information broadcast by the serving cell to which the receiving UE belongs.

[0019] Optionally, receiving the first instruction includes at least one of the following methods: receiving the first instruction transmitted via broadcast; receiving the first instruction transmitted via multicast; and receiving the first instruction transmitted via unicast.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0056] To better understand the control method for direct sidelink discontinuous reception of DRX disclosed in this disclosure, the communication system to which this disclosure applies is first described below.

[0057] To better understand the control method for direct sidelink discontinuous reception of DRX disclosed in this disclosure, the communication system to which this disclosure applies is first described below.

[0058] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. The communication system may include, but is not limited to, a network device, a transmitting UE, and a receiving UE. The transmitting UE and the receiving UE can communicate with the network device separately, and the transmitting UE and the receiving UE can communicate with each other. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this application. In actual applications, there may be two or more network devices, two or more transmitting UEs, and two or more receiving UEs. Figure 1 The communication system shown is an example comprising a network device 101, a transmitting UE 102, and a receiving UE 103.

[0059] As an example, a user equipment (UE) can function as both a receiving UE and a transmitting UE.

[0060] As another example, one user equipment (UE) can function as a receiving UE alone, and another user equipment (UE) can function as a transmitting UE alone.

[0061] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0062] The network device in this disclosure is an entity on the network side used to transmit or receive signals. For example, network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network device. The network device provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure, the protocol layer of a network device, such as a base station, can be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0063] The user equipment in this disclosure is an entity on the user side used to receive or transmit signals, such as a mobile phone. Terminal equipment can also be called a terminal, mobile station (MS), mobile terminal (MT), etc. User equipment can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. This disclosure does not limit the specific technology or device form used in the user equipment.

[0064] In this embodiment of the disclosure, the relay UE is a UE that provides relay functionality.

[0065] To save power consumption during direct communication between User Equipment (UE) and UE, Discontinuous Reception (DRX) is introduced. The transmitting UE only sends sidelink data during the active time of the receiving UE to avoid data loss.

[0066] If UE A is in cell 1 that supports sidelink DRX, while UE B is in cell 2 that does not support sidelink DRX, then if UE A only performs sidelink reception during the sidelink DRX activation time for broadcast and multicast, it may not be able to receive the sidelink broadcast and multicast data sent by UE B.

[0067] To address the aforementioned issues, this disclosure proposes a control method and apparatus for direct sidelink discontinuous DRX reception.

[0068] Figure 2 This is a flowchart illustrating a control method for discontinuous DRX reception via a direct sidelink according to an embodiment of this disclosure. It should be noted that the control method for discontinuous DRX reception via a direct sidelink according to an embodiment of this disclosure can be applied to a transmitting user equipment (UE).

[0069] Step 201: When a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs.

[0070] The first indication is used to indicate that the cell does not support sidelink DRX.

[0071] In this embodiment of the disclosure, the transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information block type 12 (SIB12). In response to not carrying sidelink DRX parameters for multicast and broadcast, the transmitting UE sends a first indication to other UEs.

[0072] As one possible implementation, the other UEs are receiving UEs other than the transmitting UE itself.

[0073] The receiving UE and / or other UEs can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the receiving UE and / or other UEs may differ in different systems. For example, in a 5G system, a wireless UE can communicate with one or more CNs (Core Networks) via a RAN. The first wireless UE can be a mobile UE, such as a mobile phone (or "cellular"), and a computer with a mobile UE, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the radio access network.

[0074] For example, the receiving UE and / or other UEs can be PCS (Personal Communication Service) phones, cordless phones, SIP (Session Initiated Protocol) phones, WLL (Wireless Local Loop) stations, PDAs (Personal Digital Assistants), etc. The wireless UE can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile device, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device; however, this disclosure does not limit the terminology used in the embodiments.

[0075] In summary, in this technical solution, when the transmitting UE detects a cell that does not support sidelink DRX, it sends a first indication to other UEs. This 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. In response to the first indication, the receiving UE continues to listen for sidelink communication and does not start sidelink DRX, which can prevent the UE from being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX.

[0076] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 4This is a flowchart illustrating another control method for direct sidelink discontinuous DRX reception provided in an embodiment of this disclosure. This control method for direct sidelink discontinuous DRX reception can be applied to a transmitting UE. This control method for direct sidelink discontinuous DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0077] like Figure 3 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0078] Step 301: Detect whether there are any cells that do not support sidelink DRX.

[0079] In this embodiment of the disclosure, the transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information block type 12 (SIB12).

[0080] Step 302: When a cell that does not support sidelink DRX is detected, the step of sending a first indication to other UEs is performed. The first indication also includes the cell's identifier.

[0081] The first indication includes a cell identifier, which indicates which specific cell it refers to. This cell can be the serving cell to which the UE belongs, or it can be a non-serving cell to which the UE belongs.

[0082] As one possible implementation, the first instruction includes the frequency of the cell.

[0083] As one possible implementation, the first instruction includes the cell identifier and the frequency at which the cell is located.

[0084] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 4 This is a flowchart illustrating another control method for direct sidelink discontinuous DRX reception provided in an embodiment of this disclosure. This control method for direct sidelink discontinuous DRX reception can be applied to a first UE. This control method for direct sidelink discontinuous DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0085] like Figure 4 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0086] Step 401: Detect whether there are any cells that do not support sidelink DRX.

[0087] In this embodiment of the disclosure, the transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information block type 12 (SIB12).

[0088] Step 402: When a cell that does not support sidelink DRX is detected, the transmitting UE satisfies the first condition.

[0089] In this embodiment of the disclosure, the transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information (SIB12). In response to not carrying sidelink DRX parameters for multicast and broadcast, the transmitting UE sends a first indication to other UEs.

[0090] To reduce the consumption of cell processing resources, if the sending UE meets the first condition, step 403 continues; if the sending UE does not meet the first condition, the first indication sent to other UEs is ignored, so as to save unnecessary consumption of cell processing resources.

[0091] Step 403: In response to the first condition being met, send a first indication to other UEs.

[0092] As one possible implementation, the other UEs are receiving UEs other than the transmitting UE itself.

[0093] Other UEs (or receiving UEs) do not activate sidelink DRX according to the first instruction, so that the receiving UE continues to listen for sidelink communication in response to the first instruction and does not activate sidelink DRX. This can prevent the UE from being unable to receive broadcast and multicast data from other UEs under the control of cells that do not support sidelink DRX.

[0094] In summary, in this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX; when a cell that does not support sidelink DRX is detected, it further determines whether the sending UE meets a first condition. In response to meeting the first condition, it continues to send a first instruction to other UEs so that the receiving UE does not start sidelink DRX according to the first instruction. This allows the receiving UE to continuously listen for sidelink communication in response to the first instruction and not start sidelink DRX. This avoids the UE being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX. In addition, it can also save unnecessary consumption of cell processing resources.

[0095] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 5 This is a flowchart illustrating another control method for direct sidelink discontinuous DRX reception provided in an embodiment of this disclosure. This control method for direct sidelink discontinuous DRX reception can be applied to a first UE. This control method for direct sidelink discontinuous DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0096] like Figure 5 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0097] Step 501: Detect whether there are any cells that do not support sidelink DRX.

[0098] In this embodiment of the disclosure, the transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information block type 12 (SIB12).

[0099] Step 502: When a cell that does not support sidelink DRX is detected, in response to the transmitting UE satisfying the first condition, the first condition being that the channel measurement result between the transmitting UE and its serving cell is less than a first threshold value.

[0100] In this embodiment of the disclosure, the transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information (SIB12). In response to not carrying sidelink DRX parameters for multicast and broadcast, the transmitting UE sends a first indication to other UEs.

[0101] To reduce the consumption of cell processing resources, if the sending UE meets the first condition, step 403 continues; if the sending UE does not meet the first condition, the first indication sent to other UEs is ignored, so as to save unnecessary consumption of cell processing resources.

[0102] As one possible implementation, the first condition is that the channel measurement result between the transmitting UE and its serving cell is less than a first threshold value. In this embodiment of the disclosure, the wireless channel measurement can characterize the signal received power, wherein, in different communication systems, the received power corresponding to at least one wireless channel measurement of the transmitting UE is also different.

[0103] As one possible implementation, the wireless channel measurement result is the Reference Signal Receiving Power (RSRP).

[0104] Step 503: In response to the first condition being met, send a first indication to other UEs.

[0105] As one possible implementation, the other UEs are receiving UEs other than the transmitting UE itself.

[0106] Other UEs (or receiving UEs) do not activate sidelink DRX according to the first instruction, so that the receiving UE continues to listen for sidelink communication in response to the first instruction and does not activate sidelink DRX. This can prevent the UE from being unable to receive broadcast and multicast data from other UEs under the control of cells that do not support sidelink DRX.

[0107] In summary, in this technical solution, the transmitting UE detects whether there is a cell that does not support sidelink DRX. When a cell that does not support sidelink DRX is detected, it further determines whether the transmitting UE meets a first condition. In response to meeting the first condition, which is that the channel measurement result between the transmitting UE and its serving cell is less than a first threshold value, it continues to send a first instruction to other UEs so that the receiving UE does not start sidelink DRX according to the first instruction. This allows the receiving UE to continuously listen to sidelink communication in response to the first instruction without starting sidelink DRX, thus avoiding the UE being unable to receive broadcast and multicast data from other UEs under the control of cells that do not support sidelink DRX. In addition, it can also save unnecessary consumption of cell processing resources.

[0108] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 6 This is a flowchart illustrating another control method for direct sidelink discontinuous DRX reception provided in an embodiment of this disclosure. This control method for direct sidelink discontinuous DRX reception can be applied to a first UE. This control method for direct sidelink discontinuous DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0109] like Figure 6 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0110] Step 601: Detect whether there are any cells that do not support sidelink DRX.

[0111] As one possible implementation, a cell that does not support sidelink DRX needs to meet the following condition: it is the serving cell to which the transmitting UE belongs.

[0112] As one possible implementation, cells that do not support sidelink DRX need to meet the following condition: they must be operating at a sidelink frequency.

[0113] As one possible implementation, cells that do not support sidelink DRX need to meet the following condition: support sidelink functionality.

[0114] As one possible implementation, cells that do not support sidelink DRX need to meet the following condition: they do not carry sidelink transmission resources in their system information.

[0115] As a possible implementation, a cell that does not support sidelink DRX needs to meet the following conditions: it is the serving cell to which the transmitting UE belongs, it is on a sidelink operating frequency, it supports sidelink functionality, and / or it does not carry sidelink transmission resources in the system information, or any combination of two or more of these conditions.

[0116] As an example, the frequency at which a cell that does not support sidelink DRX operates on the sidelink can be determined based on pre-configuration or higher-level configuration.

[0117] As an example, whether a cell that does not support sidelink DRX supports the sidelink function needs to be determined in response to the sidelink system information.

[0118] Step 602: When a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs, the first indication being used to indicate that the cell does not support sidelink DRX.

[0119] In this embodiment of the disclosure, the transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information (SIB12). In response to not carrying sidelink DRX parameters for multicast and broadcast, the transmitting UE sends a first indication to other UEs.

[0120] As one possible implementation, the other UEs are receiving UEs other than the transmitting UE itself.

[0121] In summary, in this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX; when a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs. This 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. In response to the first indication, the receiving UE continues to listen for sidelink communication and does not start sidelink DRX, which can prevent the UE from being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX.

[0122] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 7This is a flowchart illustrating another control method for direct sidelink discontinuous DRX reception provided in an embodiment of this disclosure. This control method for direct sidelink discontinuous DRX reception can be applied to a first UE. This control method for direct sidelink discontinuous DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0123] like Figure 7 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0124] Step 701: Detect whether there are any cells that do not support sidelink DRX.

[0125] Step 702: When a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs. The first indication is used to indicate that the cell does not support sidelink DRX.

[0126] In this embodiment of the disclosure, the transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information (SIB12). In response to not carrying sidelink DRX parameters for multicast and broadcast, the transmitting UE sends a first indication to other UEs.

[0127] As one possible implementation, the other UEs are receiving UEs other than the transmitting UE itself.

[0128] Sending the first indication to other UEs is performed in at least one of the following ways: sending the first indication to other UEs via broadcast, sending the first indication to other UEs via multicast, and sending the first indication to other UEs via unicast.

[0129] In summary, in this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX; when a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs. This 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. In response to the first indication, the receiving UE continues to listen for sidelink communication and does not start sidelink DRX, which can prevent the UE from being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX.

[0130] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 9 This is a flowchart illustrating another control method for discontinuous direct sidelink DRX reception provided in an embodiment of this disclosure. This path switching method can be applied to a receiving user equipment (UE). The control of discontinuous direct sidelink DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0131] like Figure 9 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0132] Step 901: Receive a first indication, which indicates that the cell does not support sidelink DRX.

[0133] The transmitting UE determines whether the cell supports sidelink DRX based on whether the cell carries sidelink DRX parameters for multicast and broadcast in the system information block type 12 (SIB12). In response to the absence of sidelink DRX parameters for multicast and broadcast, the transmitting UE sends a first indication to the receiving UE (or other UEs besides the transmitting UE).

[0134] Step 902: In response to the first instruction, continue listening to sidelink communication and do not start the sidelink DRX.

[0135] In this embodiment of the disclosure, to avoid the receiving UE being unable to receive data from the transmitting UE under the control of a cell that does not support sidelink DRX, the receiving UE will continuously listen for sidelink communication and will not activate sidelink DRX.

[0136] It should be noted that the above embodiments are illustrated using one transmitting UE and one receiving UE as an example. In practical applications, there may be two or more transmitting UEs and two or more receiving UEs. The control method for direct sidelink discontinuous reception DRX used in each is based on the same principle, therefore, this disclosure will not elaborate on it further.

[0137] In this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX; when a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs. 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. In order to respond to the first indication, the receiving UE continues to listen for sidelink communication and does not start sidelink DRX, which can prevent the UE from being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX.

[0138] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 10 This is a flowchart illustrating another control method for discontinuous direct sidelink DRX reception provided in an embodiment of this disclosure. This path switching method can be applied to a receiving user equipment (UE). The control of discontinuous direct sidelink DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0139] like Figure 10 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0140] Step 1001: Receive a first indication, the first indication being used to indicate that the cell does not support sidelink DRX, the first indication including the frequency of the cell.

[0141] The transmitting UE obtains the frequency of the serving cell of the transmitting UE by communicating with the sidelink of the network device, and after confirming that the cell does not support sidelink DRX, sends it to the receiving UE along with the first indication.

[0142] As one possible implementation, the first instruction also includes a cell identifier, which is used to indicate the cell identifier of the serving cell to which the sending UE belongs.

[0143] Step 1002: In response to the first indication carrying the frequency of the cell, perform the continuous listening sidelink communication on the frequency, without starting the sidelink DRX.

[0144] In this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX. When a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs. The first indication includes the frequency of the cell, indicating that the cell does not support sidelink DRX. In response to the first indication, the receiving UE carries the frequency of the cell and performs continuous listening to sidelink communication on that frequency without starting sidelink DRX. This prevents the UE from being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX.

[0145] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 11 This is a flowchart illustrating another control method for discontinuous direct sidelink DRX reception provided in an embodiment of this disclosure. This path switching method can be applied to a receiving user equipment (UE). The control of discontinuous direct sidelink DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0146] like Figure 11 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0147] Step 1101: Receive a first indication, which indicates that the cell does not support sidelink DRX. The first indication includes the cell's identifier.

[0148] Step 1102: In response to the first instruction carrying the identifier of the cell, determine whether the serving cell to which the receiving UE belongs is a neighboring cell of the cell corresponding to the identifier of the cell.

[0149] Step 1103: If the serving cell to which the receiving UE belongs is a neighboring cell of the cell whose identifier corresponds to the cell, perform the continuous listening sidelink communication in the neighboring cell of the cell, and do not start the sidelink DRX.

[0150] In this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX. When a cell that does not support sidelink DRX is detected, a first indication containing the cell's identifier is sent to other UEs. This first indication is used to indicate that the cell does not support sidelink DRX. If the serving cell of the receiving UE is a neighboring cell of the cell corresponding to the cell's identifier, the receiving UE performs continuous listening sidelink communication in the neighboring cell of the cell according to the first indication, without starting sidelink DRX. This avoids the UE being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX.

[0151] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 12 This is a flowchart illustrating another control method for discontinuous direct sidelink DRX reception provided in an embodiment of this disclosure. This path switching method can be applied to a receiving user equipment (UE). The control of discontinuous direct sidelink DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0152] like Figure 12 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0153] Step 1201: Receive a first indication, which indicates that the cell does not support sidelink DRX. The first indication includes the cell's identifier.

[0154] Step 1202: In response to the first instruction carrying the identifier of the cell, determine whether the serving cell to which the receiving UE belongs is a neighboring cell of the cell based on the neighboring cell information broadcast by the serving cell to which the receiving UE belongs.

[0155] Step 1203: If the serving cell to which the receiving UE belongs is a neighboring cell of the cell whose identifier corresponds to the cell, perform the continuous listening sidelink communication in the neighboring cell of the cell, and do not start the sidelink DRX.

[0156] In this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX. When a cell that does not support sidelink DRX is detected, a first indication containing the cell's identifier is sent to other UEs. If it is determined whether the serving cell to which the receiving UE belongs is a neighboring cell of the cell based on the neighboring cell information broadcast by the serving cell to which the receiving UE belongs, the receiving UE performs the continuous listening sidelink communication in the neighboring cell of the cell according to the first indication, without starting sidelink DRX. This can prevent the UE from being unable to receive sidelink data from other UEs under the control of cells that do not support sidelink DRX.

[0157] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 13 This is a flowchart illustrating another control method for discontinuous direct sidelink DRX reception provided in an embodiment of this disclosure. This path switching method can be applied to a receiving user equipment (UE). The control of discontinuous direct sidelink DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0158] like Figure 13 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0159] Step 1301: Receive a first indication, which indicates that the cell does not support sidelink DRX. The first indication includes the frequency of the cell.

[0160] As one possible implementation, receiving the first instruction includes at least one of the following methods: receiving the first instruction transmitted via broadcast, receiving the first instruction transmitted via multicast, and receiving the first instruction transmitted via unicast.

[0161] Step 1302: In response to the first instruction carrying the frequency of the cell, perform the continuous listening sidelink communication on the frequency without starting the sidelink DRX.

[0162] As one possible implementation, corresponding to different ways of receiving the first instruction, continuous listening is performed on the sidelink communication.

[0163] For example, when the first indication is received via broadcast, the continuous listening to sidelink communication is performed, but the sidelink DRX is not started. When the first indication is received via multicast, the continuous listening to sidelink communication is performed, but the sidelink DRX is not started.

[0164] In this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX; when a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs. 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. In order to respond to the first indication, the receiving UE continues to listen for sidelink communication and does not start sidelink DRX, which can prevent the UE from being unable to receive broadcast and multicast data from other UEs under the control of cells that do not support sidelink DRX.

[0165] This disclosure provides another control method for direct sidelink discontinuous DRX reception. Figure 14 This is a flowchart illustrating another control method for discontinuous direct sidelink DRX reception provided in an embodiment of this disclosure. This path switching method can be applied to a receiving user equipment (UE). The control of discontinuous direct sidelink DRX reception can be executed alone, or it can be executed together with any embodiment of this disclosure or possible implementations in the embodiments, or it can be executed together with any technical solution in the related technologies.

[0166] like Figure 14 As shown, the control method for the direct sidelink discontinuous reception DRX may include the following steps:

[0167] Step 1401: Receive a first indication, which indicates that the cell does not support sidelink DRX.

[0168] Receiving the first instruction includes at least one of the following methods: receiving the first instruction transmitted via broadcast, or receiving the first instruction transmitted via multicast.

[0169] Step 1402, in response to the first instruction, do not start sidelink DRX for broadcast or multicast listening.

[0170] As one possible implementation, corresponding to the multicast or broadcast mode of receiving the first instruction, continuous listening is performed on the sidelink communication, and the sidelink DRX is not started for broadcast or multicast listening.

[0171] In this technical solution, the sending UE detects whether there is a cell that does not support sidelink DRX; when a cell that does not support sidelink DRX is detected, a first indication is sent to other UEs. 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. In order to respond to the first indication, the receiving UE continues to listen for sidelink communication and does not start sidelink DRX, which can prevent the UE from being unable to receive broadcast and multicast data from other UEs under the control of cells that do not support sidelink DRX.

[0172] It should be noted that the aforementioned Figures 2 to 9 The explanation of the control method for direct sidelink discontinuous reception DRX executed by the transmitting UE in any embodiment also applies to the control method for direct sidelink discontinuous reception DRX executed by the receiving UE in this embodiment. The implementation principle is similar and will not be repeated here.

[0173] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

Therefore, the implementation of the control method for discontinuous DRX reception via a direct sidelink is also applicable to the control device for discontinuous DRX reception via a direct sidelink provided in the embodiments of this disclosure. It will not be described in detail in the embodiments of this disclosure.
