Some concepts and/or terms related to the access method, the residence method, the apparatus, the user equipment and the storage medium provided in the embodiments of the present application are explained below.

1. Side link (sidelink)

The lte system supports sidelink, which may also be referred to as a sidelink or an sidelink, for direct data transmission between UEs without a network device.

The UE transmits sidelink control information (Sidelink Control Information, SCI) over a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH), scheduling transmission of a physical sidelink shared channel (Physical Sidelink Shared Channel, PSCCH) to transmit data. The transmission is in a broadcast form, and the receiving end does not feed back whether the reception is successful to the transmitting end.

The LTE sidelink design supports two resource allocation modes, a scheduled resource allocation (Scheduled resource allocation) mode and an autonomous resource selection (Autonomous Resource Selection) mode, respectively. The former is controlled by the network side equipment and allocates resources for each UE, and the latter is autonomously selected by the UE.

Currently, LTE supports sidelink carrier aggregation (Carrier Aggregation, CA). The CA of LTE sidelink is different from the Uu interface (i.e., downlink and uplink) in that the CA of LTE sidelink has no separation of primary carrier (Primary component carrier, PCC) and secondary carrier (Secondary component carrier, SCC). The UE in autonomous resource selection mode performs resource sensing (sensing) and resource reservation independently on each Carrier Cell (CC).

The design of LTE sidelink may be applicable to specific public safety transactions (e.g., emergency communication in disaster sites such as fire or earthquake), or internet of vehicles (Vehicle to Everything, V2X) communication, etc. The internet of vehicles communication includes various services such as basic security type communication, advanced (automatic) driving, formation, sensor expansion, and the like. Since LTE sidelink only supports broadcast communications, it is mainly used for basic security class communications, and other advanced V2X services will be supported by New Radio (NR) sidelink.

The fifth generation (the fifth generation, 5G) mobile communication NR system can be used for an operating frequency band above 6GHz that is not supported by LTE, and supports a larger operating bandwidth, but the current version of NR system only supports an interface between a base station (gNB) and a UE, and does not support a Sidelink interface for direct communication between UEs.

Specifically, in the ProSe network architecture, a communication interface between terminals is called a PC5 interface, and an interface where UE is connected to access network devices such as a terrestrial radio access network (UMTS Terrestrial Radio Access Network, UMTS E-UTRAN) is called a Uu interface.

2. Transmission form of sidelink

Current sidelink transmission is also mainly broadcast (multicast), multicast (multicast), and unicast (unicast) in several transmission modes. Unicast is a transmission in one-to-one (i.e., one to one) format. Multicasting is a one-to-many (i.e., one-to-many) form of transmission. Broadcast is also a one-to-many (i.e., one-to-many) form of transmission, but broadcast does not have the concept that UEs belong to the same group.

Currently, the Sidelink unicast and multicast communications support the feedback mechanism of physical layer hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ).

Currently, NR sidelink defines two modes (modes), one is mode1, where the base station schedules resources, and one is mode2, where the UE itself can decide what resources to use for transmission, where the resource information may come from a broadcast message or a pre-configuration of the base station. If the UE is operating within range of the base station and is in radio resource control (Radio Resource Control, RRC) connection with the base station, then resource transmission is performed through mode1 and/or mode2; if the UE works in the range of the base station, but does not perform RRC connection with the base station, it can only work in mode2; if the UE is out of range of the base station, it can only operate in mode2. In addition, when V2X transmission is performed according to preconfigured information, mode2 may be further divided into 2a,2b,2c, and 2d.

3. Resource pool

Currently, V2X transmission has a concept of "resource pool", where the resource pool is sent or preconfigured by a network side device, and the resource pool includes resources used for transmission and many transmission related parameters, such as in LTE, an offset value of a first subframe of the resource pool, a Bitmap (Bitmap) corresponding to the resource pool, whether PSCCH and PSSCH will be transmitted on adjacent unlimited bearers (RBs), a number of subchannels and a size of each subchannel, a lowest RB index value corresponding to a PSCCH pool, a received signal strength indication (Received Signal Strength Indication, S-RSSI) threshold measured by a computer-generated report commodity index (Computer Build Report), a region identifier, and so on.

Currently, the network side device configures a common transmission resource pool for the UE, and may also configure an abnormal resource pool (abnormal pool) for some special situations, such as a handover procedure, or a radio link failure (Radio Link Failure, RLF) or a procedure of switching from an idle state (idle) to a connected state (connected).

The UE may be under different network coverage, and for different networks, the UE may select a resource pool and corresponding resources based on network scheduling, or may autonomously select a resource pool based on a pre-configuration. The selection of the resource pool may require that the resource pool associated with the region in which the UE is located is selected in consideration of the region. While the autonomous selection of resources in the resource pool is mainly based on the sending mechanism, random selection is also possible (e.g. for the selection of resources in the abnormal resource pool).

4. Unlicensed band new wireless (Unlicensed band NR)

The unlicensed Band may be used as a supplement to Licensed bands to help operators expand communication services. To keep pace with NR deployment and maximize as much as possible unlicensed access based on NR, unlicensed bands may operate in the 5GHz,37GHz and 60GHz bands. Since unlicensed bands are shared by multiple technologies (RATs), such as wireless fidelity (Wireless Fidelity, wiFi), radar, LTE Licensed-Assisted Access (LAA), etc., unlicensed bands must be used in certain countries or regions to meet specifications to ensure that all devices can use the resources fairly, such as LBT, maximum channel occupancy time (Maximum Channel Occupancy Time, MCOT), etc.

5. Listen Before Talk (LBT)

A transmitting end working in an unlicensed frequency band needs to monitor whether the frequency band (which can be identified by a central frequency point+bandwidth) is occupied before transmitting signals, and if not, the transmitting end can transmit signals in the frequency band.

6. RRC establishment condition (Connection Establishment Condition)

In the sidelink, there is a case that V2X sidelink transmission triggers the UE to enter an RRC connected state, that is, when the IDLE UE is about to perform the V2X sidelink related communication procedure, the system message includes the related configuration of V2X but does not include the related information (such as a resource pool) of resources.

7. Three states of NR RRC

The UE in Idle state has no RRC context on the network side device, that is, the parameters necessary for communication between the network side device and the UE do not belong to a specific cell, and the network side device does not know whether the UE exists. The UE is assigned a unique identity in the Tracking Area (TA). From the core network point of view, the device is in cn_idle state. In order to reduce power consumption, the UE is in a dormant state most of the time, and thus cannot perform data transmission. In the downlink, a UE in Idle state may wake up periodically to receive paging messages from the network. Mobility (Mobility) may be handled by the UE for cell reselection. In Idle state, the UE and the network side device will not keep uplink synchronization, and if the UE is to be transferred from Idle state to Connected state, RRC context can be established between the UE and the network side device only through Random Access (Random Access).

In the RRC Connected state, an RRC context may be established and all parameters required for communication are known to both entities (UE and network side device). From the core network point of view, the UE is in cn_connected state. The cell to which the UE belongs is known and has been configured with a device identity, i.e. a cell radio network temporary identifier (C-RNTI), for transmission signalling purposes between the device and the network. The connected state may transmit data, but since the data stream of the packet is generally bursty, power consumption may be reduced by turning off the reception circuitry of the UE when no data stream is transmitted, employing discontinuous reception (Discontinuous Reception, DRX) techniques. Since the RRC context has been established in the gNB in the connected state, it is relatively fast to leave DRX and start receiving/transmitting data. In the connected state, mobility may be handled by the network side device, i.e. the UE provides neighbor cell measurements to the network, which instructs the device to perform a handover. Uplink time synchronization may or may not exist, and may be established and maintained by using random access when there is data to be transmitted. In LTE, only idle and connected states are supported. A common situation in practice is to use the idle state as the primary sleep state of the UE to save power. However, since there is often frequent transmission of small data packets in some smartphones, there are a large number of idle to connected transitions if in LTE. These transitions increase signaling load and signaling delay. Therefore, in order to reduce signaling load and latency, an INACTIVE state (rrc_inactive) state is introduced in the NR.

In the rrc_inactive state, the RRC context of the network side device and the UE side is maintained. From the core network point of view, the UE is in cn_connected state. The transition from the inactive state to the connected state is fast and no core network signaling is required. At the same time, the UE is allowed to sleep in an idle state like manner and mobility is handled through cell reselection. Thus, rrc_inactive may be considered as a mixture of idle and connected states.

The following describes in detail the access method provided in the embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Currently, in LTE V2X, network side equipment can regulate and control resources of UE through configuration, and can control the UE to enter a connection state in practice, so as to facilitate the subsequent UE to request for transmission resources and other purposes. On the unlicensed band, the sidelink UE may not perform data transmission based on the resource pool configuration any more, and it is not clear (i.e. problem 1) what configuration the network side device controls when the UE in idle state or inactive state can enter the connected state. In addition, for the UE in idle state or inactive state, it is not clear how the network side device adjusts the residence condition of the UE on the unlicensed band (i.e. problem 2).

Aiming at the problem 1, the embodiment of the application provides an access method, wherein the UE can flexibly determine whether to enter a connection state according to target information, namely, the UE can judge whether to establish connection based on related information of an unlicensed frequency band, so that the state transition condition of the UE in an idle state or an inactive state is flexibly regulated and controlled.

Aiming at the problem 2, the embodiment of the application provides a residence method, wherein the UE can flexibly determine the frequency point to be resided in the cell selection or reselection process of the UE according to the target information, namely the UE can reside in the cell/frequency point based on the related information of the unlicensed frequency band, so that the residence condition of the UE in the cell selection or reselection process is flexibly regulated and controlled.

Example 1

An embodiment of the present application provides an access method, and fig. 2 shows a flowchart of an access method provided by an embodiment of the present application. As shown in fig. 2, the access method provided in the embodiment of the present application may include the following

steps

201 and 202.

Step 201, the UE acquires target information.

Optionally, in the embodiment of the present application, the target information may be configured by a network side device, preconfigured, predefined, agreed-upon by a protocol, or autonomously decided by a UE, etc.

Optionally, in the embodiment of the present application, the network side device may regulate and control the behavior of the UE in the idle state and the inactive state, and send the target information to the UE.

Step 202, the UE determines whether to enter a connection state according to the target information.

In an embodiment of the present application, the target information includes at least one of the following: related configuration information of unlicensed frequency bands, service requirement information of UE, LBT information and first indication information. The LBT information is used for indicating whether the UE generates continuous LBT failure or not; the first indication information is used for indicating whether the network side equipment supports sensing or resource selection on an unlicensed frequency band.

In this embodiment of the present application, the UE may determine whether to trigger establishment of RRC connection according to the target information (i.e., related information of the unlicensed band) to determine whether the UE enters the connected state from the inactive state or the idle state.

It should be noted that, the related configuration information of the unlicensed band may be understood as: the network side equipment configures information related to an unlicensed frequency band for the UE so as to be used for the UE to determine whether to enter a connection state.

Note that the above sensing or resource selection is: if the base station starts a 5G air interface (NewRadio in Unlicensed Spectrum, NR-U) working in an unlicensed frequency band, the base station is indicated to support sensing or resource selection on an unlicensed frequency band, and at the moment, the UE can trigger to establish RRC connection and enter a connection state, or scheduling of a mode 1 has better performance; if the base station does not support sensing or resource selection, the scheduling of mode 1 is blind scheduling, the UE may not trigger establishment of RRC connection.

Alternatively, in the embodiment of the present application, the above step 202 may be specifically implemented by the following step 202 a.

In step 202a, when the configuration information of the network side device includes related configuration information of the sidelink and does not include transmission resource information of the sidelink, the UE determines whether to enter a connection state according to the target information.

In this embodiment of the present application, the transmission resource information of the sidelink is resource information for sidelink transmission, and the transmission resource information may include at least one of the following: a common resource pool and an abnormal resource pool.

In the embodiment of the present invention, when the configuration information related to the sidelink is included in the configuration of the network side device and no resource information for sidelink transmission is included, the UE may decide whether to trigger RRC connection establishment based on the configuration of the network side device and/or whether the sidelink transmission occurs in an unlicensed frequency band, or when the configuration information related to the sidelink is included in the configuration of the network side device and no resource information for sidelink transmission is included in the configuration of the network side device, the UE may also decide whether to trigger RRC connection establishment based on the transmission condition of the unlicensed frequency band, that is, the LBT success or failure condition of the UE itself, so that the network side device in sidelink transmission may flexibly regulate the state transition or residence condition of the UE in an idle state or an inactive state through the configuration, so that better cooperation and control between the network side device and the UE are realized on the unlicensed frequency band.

Optionally, in the embodiment of the present application, the UE may further determine, according to the target information, whether to trigger establishment of RRC connection to determine whether to enter a connected state if the network side device configuration does not include configuration information related to a sidelink; or, when the network side device configuration does not include the resource information (the common resource pool and/or the abnormal resource pool) for the sidelink transmission, the UE may determine whether to trigger to establish the RRC connection according to the target information, so as to determine whether to enter a connected state; or, when the UE does not include configuration information related to the sidelink or resource information (a common resource pool and/or an abnormal resource pool) for sidelink transmission in the configuration of the network side device, determining whether to trigger establishment of RRC connection according to the target information so as to determine whether to enter a connection state; alternatively, the UE may further include resource information (a common resource pool and/or an abnormal resource pool) for the sidelink transmission in the configuration of the network side device, but determine whether to trigger establishment of the RRC connection according to the target information to determine whether to enter the connected state when the sidelink related configuration information is not included.

Optionally, in a first implementation manner of the embodiment of the present application, the target information includes related configuration information of an unlicensed band, and the step 202 may be specifically implemented by the following steps 202b and 202 c.

Step 202b, the UE receives second indication information sent by the network side device.

In this embodiment of the present application, the second indication information includes related configuration information of an unlicensed band, where the second indication information is used to indicate whether or not to allow or need the UE to perform sidelink transmission in the unlicensed band.

Step 202c, the UE determines whether to trigger to establish RRC connection according to the second indication information.

In this embodiment of the present application, after acquiring relevant configuration information of an unlicensed band sent by a receiving network side device, the UE may determine whether to trigger establishment of RRC connection based on the relevant configuration information of the unlicensed band, so as to determine whether to enter a connected state.

For example, if the UE receives the 1bit indicated by the network side device, the UE triggers to establish the RRC connection when the value is 1, so as to enter a connected state, and does not trigger to establish the RRC connection when the value is 0; or when the value is 0, the RRC connection is triggered to be established so as to enter a connection state, and when the value is 1, the RRC connection is not triggered to be established.

In the embodiment of the application, on the unlicensed frequency band, the network side equipment in the side link transmission can flexibly regulate and control the state transition condition of the idle state or the inactive state UE through configuration, so that better cooperation and control between the network side equipment and the UE are realized on the unlicensed frequency band.

Optionally, in a second implementation manner of the embodiment of the present application, the target information includes service requirement information of the UE, and the step 202 may be specifically implemented by the following step 202 d.

In step 202d, if the first service meets the first condition, the UE triggers to establish an RRC connection, or the UE does not trigger to establish an RRC connection.

In this embodiment of the present application, the first service is a service currently transmitted or to be transmitted by the UE. The first condition is any one of the following: the UE supports transmission of the first service on the unlicensed band and the UE upper layer indicates that the first service is allowed or required to be transmitted on the unlicensed band.

Optionally, in the embodiment of the present application, when the UE currently transmits or the service to be transmitted supports transmission in an unlicensed band, or the upper layer indicates that transmission in the unlicensed band is possible/required, the UE does not trigger establishment of RRC connection.

Optionally, in the embodiment of the present application, when the UE currently transmits or the service to be transmitted supports transmission in an unlicensed band, or the upper layer indicates that transmission in the unlicensed band is possible/required, the UE triggers establishment of RRC connection.

Optionally, in a third implementation manner of the embodiment of the present application, the target information includes related configuration information of an unlicensed band and service requirement information of the UE, and the step 202 may be specifically implemented through a step 202e described below.

In step 202e, when the network side device indicates that the UE is allowed or required to perform sidelink transmission in the unlicensed band and the first service satisfies the first condition, the UE triggers to establish RRC connection, or the UE does not trigger to establish RRC connection.

In this embodiment of the present application, the first service is a service currently transmitted or to be transmitted by the UE.

In the embodiment of the application, the UE may decide whether to trigger establishment of the RRC connection based on the traffic situation of its own transmission.

Optionally, in the embodiment of the present application, the network side device indicates that the permission or the requirement of the sidelink transmission occurs in an unlicensed band, and the UE does not trigger to establish the RRC connection if the UE currently transmits or the service to be transmitted supports transmission in the unlicensed band or an upper layer indicates that the transmission can/needs to be performed in the unlicensed band.

Optionally, in the embodiment of the present application, the network side device indicates that the permission or the requirement of the sidelink transmission occurs in an unlicensed frequency band, and the UE triggers to establish the RRC connection if the UE currently transmits or the service to be transmitted supports transmission in the unlicensed frequency band or an upper layer indicates that the UE can/needs to transmit in the unlicensed frequency band.

Optionally, in a fourth implementation manner of the embodiment of the present application, the target information includes LBT information, and the step 202 may be specifically implemented by a step 202f or a step 202g described below.

Step 202f, in case of continuous LBT failure of the UE, the UE triggers to establish RRC connection.

In the embodiment of the application, the UE may decide whether to trigger establishment of the RRC connection based on the LBT success or failure condition of itself.

Optionally, in the embodiment of the present application, the UE may not trigger RRC connection establishment first, and if the UE fails to perform continuous LBT, the UE triggers RRC connection establishment.

Example two

An embodiment of the present application provides a residence method, and fig. 3 shows a flowchart of the residence method provided by the embodiment of the present application. As shown in fig. 3, the access method provided in the embodiment of the present application may include the following

steps

301 and 302.

Step 301, the UE acquires target information.

Step 302, the UE determines a frequency point to be resided in a cell selection or reselection process according to the target information.

In this embodiment of the present application, the target information includes configuration information related to cell selection or reselection.

It should be noted that, for the target information, reference may be made to the description in the first embodiment, and the description is omitted here

Alternatively, in the embodiment of the present application, the above step 302 may be specifically implemented by the following steps 302a and 302 b.

Step 302a, the UE acquires first configuration information.

In this embodiment of the present application, the first configuration information is configuration information related to cell selection or reselection.

Step 302b, the UE determines a frequency point to be resided in a cell selection or reselection process according to the first configuration information and the target information.

Optionally, in the embodiment of the present application, the target information includes service requirement information, and the step 302b may be specifically implemented by the following step 302 c.

Step 302c, under the condition that the first service meets the first condition, the UE determines a frequency point to be resided in a cell selection or reselection process according to the first configuration information and the target information.

Wherein the first condition is any one of: the UE supports transmission of the first service on the unlicensed band and the network device indicates that the first service is allowed or required to be transmitted on the unlicensed band.

In this embodiment of the present application, the first service refers to a service that is currently transmitted or transmitted with UE.

Optionally, in the embodiment of the present application, the UE may determine a frequency point to be camped in a cell selection or reselection process based on a current transmission or a service condition to be transmitted.

Optionally, in the embodiment of the present application, if the UE currently transmits or the service to be transmitted supports transmission in an unlicensed band, or the upper layer indicates that transmission in the unlicensed band is possible/required, the UE may preferentially select the unlicensed band to camp.

The above-mentioned preference may be to directly select a certain frequency point, or may be to add an offset value to the priority of the certain frequency point and then compare the offset value with other frequency points, where the offset value may be configured or preconfigured by the base station.

Optionally, in the embodiment of the present application, if the UE currently transmits or the service to be transmitted supports transmission in an unlicensed band, or the upper layer indicates that transmission in the unlicensed band is possible/required, the UE preferentially selects to camp in the licensed band.

It should be noted that, the frequency point of the authorized frequency band is preferentially selected to reside in the unlicensed frequency band, so that if the frequency point resides in the unlicensed frequency band, the scenario that the UE and the base station rob resources from each other may occur. But does not exclude that the unlicensed band frequency point is preferentially selected, for example, if the cooperative behavior of the UE and the base station is defined when some sidelink and Uu port data are both transmitted in the unlicensed band, the unlicensed band frequency point is preferentially selected to reside, and the sidelink is transmitted in the unlicensed band.

Alternatively, in the embodiment of the present application, the target information includes LBT information, and the step 302b may be specifically implemented by the following step 302d or step 302 e.

In the embodiment of the application, the UE may determine the residing frequency point based on the success or failure condition of its LBT.

Step 302d, under the condition that the UE fails in continuous LBT, the UE determines a frequency point to be resided in a cell selection or reselection process according to the first configuration information and the target information.

Optionally, in the embodiment of the present application, if the UE fails to perform LBT of the third threshold, the licensed band frequency point is preferentially selected to perform residence or the unlicensed band frequency point is preferentially selected to perform residence, where the value of the third threshold may be configured or preconfigured by the network side device.

Step 302e, determining, by the UE, a frequency point to be camped in a cell selection or reselection process according to the first configuration information and the target information when the UE fails to perform LBT or the number of times of performing LBT failure is greater than a preset threshold before the preset time.

Optionally, in this embodiment of the present application, if the UE fails LBT or fails LBT for a number of times greater than or equal to a fourth threshold before a timeout period preset by a timer, the RRC connection is triggered to be established, where the timeout period of the timer and a value of the fourth threshold may be configured or preconfigured by the network side device.

Optionally, in this embodiment of the present application, the first configuration information includes first priority information, where the first priority information is used to indicate a priority of at least one frequency point, and the step 302b may be specifically implemented through the following steps 302f and 302 g.

Step 302f, the UE determines a target frequency point from at least one frequency point according to the first priority information and the target information.

In the embodiment of the present application, the UE acquires configuration information related to cell selection or reselection, where the configuration information includes priority information of all frequency points used for cell selection or reselection, and other various configuration information used for cell selection or reselection.

In this embodiment of the present application, each frequency point in the at least one frequency point corresponds to a priority, and the UE may determine the target frequency point from the plurality of frequency points according to the plurality of frequency points, and priority information and target information corresponding to the frequency point.

Optionally, in the embodiment of the present application, according to the first priority information and the target information, the UE may determine a frequency point with the highest priority in at least one frequency point as the target frequency point; or, the UE may add an offset value to any one of the at least one frequency point according to the first priority information and the target information, and then compare the frequency point to which the offset value is added with other frequency points to determine the target frequency point.

In the embodiment of the present invention, the UE may take preferential treatment for different frequency points in the cell selection or reselection process based on whether the service transmitted by the current sidelink is in an unlicensed frequency band, for example, the frequency point where the UE preferentially resides in the (unlicensed) frequency band, i.e., the network side device may be configured to flexibly regulate and control the residence condition of the UE in an idle state or an inactive state, so that better cooperation and control between the network side device and the UE are realized on the unlicensed frequency band.

Step 302g, the UE determines the target frequency point as the frequency point where the UE is to reside in the cell selection or reselection process.

Alternatively, in the embodiment of the present application, the above step 302f may be specifically implemented by the following step 302m or step 302n1 and step 302n 2.

In step 302m, if the priorities of at least one frequency point are the same, the UE determines, according to the target information, a frequency point belonging to an authorized frequency band or an unauthorized frequency band in the at least one frequency point as a target frequency point.

In the embodiment of the present application, under the condition that the priority of at least one frequency point is the same, the UE may directly determine, as the target frequency point, the frequency point belonging to the authorized frequency band or the unauthorized frequency band in the at least one frequency point according to the target information.

Alternatively, in the embodiment of the present application, the above step 302g may be specifically implemented by the following step 302g 1.

In step 302n1, if the priorities of at least one frequency point are the same or different, the UE increases a preset offset value for the priority of the first frequency point according to the target information.

In this embodiment of the present application, the first frequency point is a frequency point belonging to an authorized frequency band or an unauthorized frequency band in at least one frequency point.

Step 302n2, the UE determines second priority information, and determines the target frequency point according to the second priority information.

In this embodiment of the present application, the second priority information is used to indicate priorities of the first frequency point and other frequency points after the preset offset value is added.

It should be noted that, in the case that the UE determines the priority of a frequency point based on the current transmission or the service condition to be transmitted and/or the successful or failed LBT condition of the UE, because the initial priorities of the frequency points are different, only an offset value can be added to a certain frequency point in advance, and then the priority information of the frequency point after the offset value is added and other frequency points can be compared, so that a certain frequency point cannot be directly selected preferentially.

Optionally, in the embodiment of the present application, after determining the second priority information, the UE may select, as the target frequency point, a frequency point corresponding to a priority with the largest priority value in the second priority information; or, after determining the second priority information, the UE may select, as the target frequency point, a frequency point corresponding to the priority of the offset value information added to the second priority information.

Optionally, in the first case in the embodiment of the present application, if at least one frequency point has the same priority, if one frequency point (for example, frequency point 1) of the at least one frequency point belongs to an authorized frequency band and another frequency point (for example, frequency point 2) of the at least one frequency point belongs to an unauthorized frequency band, the UE may determine the target frequency point according to service requirement information or LBT information of the UE.

Specifically, the manner of determining the target frequency point by the UE according to the service requirement information of the UE may include the following manner one and manner two.

Mode one: under the condition that the first service meets the first condition, the UE may preferentially select a frequency point of the unlicensed frequency band (i.e., frequency point 2) to reside, that is, the target frequency point is a frequency point belonging to the unlicensed frequency band in the at least one frequency point. It should be noted that, the preferred selection herein refers to directly selecting the frequency point 2, or after adding an offset value to the priority of the frequency point 2, comparing with other frequency points to determine the target frequency point.

Mode two: under the condition that the first service meets the first condition, the UE may preferentially select a frequency point of the licensed band (i.e., frequency point 1) to reside, that is, the target frequency point is a frequency point belonging to the licensed band in the at least one frequency point. It should be noted that, the preferred selection herein refers to directly selecting the frequency point 1, or after adding an offset value to the priority of the frequency point 1, comparing with other frequency points to determine the target frequency point.

The manner of determining the target frequency point by the UE according to the LBT information may include the following manner three and manner four.

Optionally, in the second case in the embodiment of the present application, if, in a case where the priorities of at least one frequency point are different, one frequency point (for example, frequency point 1) of the at least one frequency point belongs to an authorized frequency band, and another frequency point (for example, frequency point 2) of the at least one frequency point belongs to an unauthorized frequency band, the UE may determine that the target frequency point resides by adopting a scheme of adding an offset value in any of the above-mentioned modes (i.e., any of the above-mentioned modes one to four).

The embodiment of the application provides a residence method, wherein the UE can flexibly determine the frequency point to be resided in the cell selection or reselection process of the UE according to the target information, namely, the UE can reside in the cell/frequency point based on the related information of the unlicensed frequency band, so that the residence condition of the UE in the cell selection or reselection process is flexibly regulated and controlled.
