Description

[0001] This application is a divisional application of patent application No. 202010515074.4 (the filing date of the original application is 2020-06-08, and the invention name is network access, resource maintenance method, device, equipment and storage medium) Technical Field

[0002] The present application relates to the technical field of wireless communication networks, and in particular to a resource maintenance method, apparatus, device and storage medium. Background Art

[0003] The cellular network architecture improves the utilization of spectrum resources and system capacity through frequency reuse and cell splitting technology, supporting the rapid development of mobile communications. In order to meet the continuously increasing traffic demand, the evolution of the entire mobile communication from 1G to 5G is based on cellular networks, that is, the macro cell splitting and vertical micro cell network layering are adopted.

[0004] With the deployment of various low-power network nodes such as micro cells, small cells, home base stations and relay nodes in traditional cellular networks, cellular networks are becoming increasingly dense. Since each small cell (micro cell) is an independent cell, each time a user terminal (UE) enters a small cell, it must re-synchronize downlink and obtain the system information of the small cell. The UE will frequently switch cells during idle movement, wasting a lot of UE power consumption. If the network wants to page the UE, it needs to page in many small cells, while the UE is only located in one small cell, resulting in a large amount of downlink resource waste.

[0057] In one embodiment, the present application provides a network access method. Figure 2A flow chart of a network access method provided in an embodiment of the present application. The method can be applicable to situations where a UE needs to frequently switch cells in a dense deployment scenario. The method can be performed by a network access device provided in the present application, and the network access device can be implemented by software and / or hardware, and the method is applied to a first node.

[0058] like Figure 2 As shown, the network access method provided in the embodiment of the present application mainly includes steps S11 and S12.

[0059] S11. Receive first cell system information sent by a second node; wherein the first cell system information includes second cell configuration information.

[0060] S12. Access the second cell based on the second cell configuration information.

[0061] In this embodiment, the first node may be any one of the above user equipments. The second communication node may be any one of the above base stations. Figure 1 The second cell is as shown in Figure 1 The multiple second cells are aggregated together as a super cell, and paging, access, and data transmission are performed in the super cell.

[0062] Specifically, multiple small cells are aggregated together as a super cell, and the super cell transmits a downlink synchronization channel and a system message of the super cell. The super cell sends a paging message according to the paging configuration information in the super cell system message, that is, the small cells within a certain range or area share the same downlink synchronization channel, specifically the same subframe synchronization and frame synchronization. In addition, the sub-signal of the small cell can also be used as its own downlink synchronization channel, and the UE accessing the second cell is synchronized according to the sub-signal. Among them, each small cell can have its own sub-ID or not. Each small cell has its own small cell-specific system message, and the UE can access it on the exclusive access resources configured by each small cell system message. In addition, the exclusive access resource configuration information of the small cell can also be transmitted in the system message of the super cell.

[0063] Further, the UE searches for the downlink synchronization signal of the super cell, performs downlink synchronization with the super cell, aligns the subframe and frame with the super cell, then obtains the main system message of the super cell, obtains the radio frame number and the configuration information of the downlink control channel corresponding to the system message, detects the downlink control information corresponding to the system message on the time-frequency resource indicated by the configuration information, and after detecting the downlink control information, obtains the system message according to the time-frequency position indicated by the downlink control information, and then monitors the paging according to the paging message configuration information carried in the system message. The idle or inactive UE only monitors the paging message sent by the super cell (the small cell system message sent by the small cell does not include the small cell paging configuration information), or, when the idle or inactive UE is still resident in the small cell where the connected state is located, the UE monitors the paging message sent by the small cell (does not monitor the paging message sent by the super cell, and the small cell system message sent by the small cell includes the small cell paging configuration information), when the idle or inactive UE is not resident in the small cell where the connected state is located, the UE only monitors the paging message sent by the super cell.

[0064] Further, when selecting a cell or switching a cell, a UE in an idle or inactive state only selects a super cell for measurement, switching or residence, and does not measure the signal of a small cell, nor does it select a small cell for residence or switching; in this way, the measurement power consumption of the UE in an idle or inactive state can be reduced, the number of cell switching can be reduced, and the UE power consumption can be reduced; that is, the UE measures the small cell only when accessing, and selects the super cell or small cell access according to the measurement result. When the UE is in an idle or inactive state, it does not measure the small cell when measuring the same frequency neighboring area or the different frequency neighboring area, but measures the super cell. In this way, when switching or reselecting a cell, it will only reselect the super cell, and will not select the small cell; only the connected UE will measure the small cell when measuring the same frequency neighboring area or the different frequency neighboring area (at this time, there are three possibilities, measuring only the small cell, or measuring only the super cell, or measuring the small cell and the super cell, and the specific selection can be indicated in the small cell system message sent by the small cell), and the UE selects the small cell or the super cell for access according to the measurement result.

[0065] The super cell mentioned in this article corresponds to the first cell, and the small cell corresponds to the second cell;

[0066] In one embodiment, the second cell configuration information includes one or more of the following: second cell indication information, second cell system message configuration information, second cell sub-signal configuration information, second cell list information, and second cell access configuration information, wherein the second cell indication information is used to indicate whether there is a second cell (also indicating whether there is a second cell within the first cell range, or whether the UE needs to measure the second cell when it resides in the first cell, or, alternatively, whether the UE needs to measure the second cell when it resides in the first cell and accesses the first cell).

[0067] In one embodiment, the second cell system message configuration information includes one or more of the following:

[0068] The time-frequency position information corresponding to the second cell system information, the downlink control channel search space configuration information corresponding to the second cell system information, and the reference signal configuration information corresponding to the second cell system information.

[0069] In one embodiment, accessing the second cell based on the second cell configuration information includes: detecting a downlink control channel corresponding to a second cell system message; acquiring second cell system information based on the downlink control channel; and accessing the second cell based on the second cell system message.

[0070] The second cell system message configuration information includes second cell access configuration information. The UE selects to access the second cell according to the sub-signal of the second cell, and sends an access signal or an access channel to access the second cell according to the second cell access configuration information in the second cell system message configuration information sent by the first cell;

[0071] The second cell system message configuration information includes: list information of the second cell; the list includes a same-frequency neighbor cell list and / or an inter-frequency neighbor cell list. The UE selects a cell for measurement according to the cell list information in the second cell system message configuration information sent by the first cell, and selects cell access according to the measurement result. Alternatively, an idle or inactive UE selects a cell for measurement according to the first cell list information sent by the first cell, and selects cell switching or resident according to the measurement result.

[0072] The second cell system message configuration information further includes: second cell access control information; the second cell access control information is used to indicate whether the UE can access the second cell.

[0073] The system message of the second cell (third node) sent by the second cell includes: list information of the first cell and / or list information of the second cell; the list includes a same-frequency neighbor cell list and / or a different-frequency neighbor cell list. The UE residing in the second cell selects a cell to reside in, switch to, or reselect according to the cell list information in the system message of the second cell;

[0074] In one embodiment, the detecting the downlink control channel corresponding to the second cell system message includes: when the second cell configuration information includes second cell system message configuration information, and the second cell system message configuration information includes downlink control channel search space configuration information corresponding to the second cell system message, detecting the downlink control channel corresponding to the second cell system message on the resources corresponding to the second cell system message configuration information.

[0075] In one embodiment, the detecting of the downlink control channel corresponding to the second cell system message includes: when the second cell configuration information does not include the downlink control channel search space configuration information corresponding to the second cell system message, detecting the downlink control channel corresponding to the second cell system message at the time-frequency position of the preset search space.

[0076] In this embodiment, the downlink control information configuration corresponding to the small cell system message is configured for each small cell, such as: search space time-frequency position, mapping position, candidate set size, aggregation level information, etc.; the downlink control information includes scheduling information of the data channel carrying the small cell system message, such as: time-frequency position information of the data channel, coding and modulation information of the data channel, etc. Further, all small cells under the super cell may share the same system message configuration information, all small cells share the same downlink control information search space, or the super cell independently configures the system message of the small cell.

[0077] In one embodiment, the time-frequency position of the preset search space includes one or more of the following modes: a preset fixed time-frequency position, a preset offset relative to the SSB time-frequency position of the first cell, and a preset offset relative to the sub-signal time-frequency position.

[0078] In one embodiment, accessing the second cell based on the second cell system message includes: detecting a sub-signal of the second cell; and selecting a second cell whose sub-signal meets the requirements to access the network.

[0079] In one embodiment, the second cell whose sub-signal meets the requirement includes one or more of the following: the second cell with the strongest sub-signal strength, any second cell in the set of second cells whose sub-signal strength exceeds a threshold, and a second cell whose signal strength is greater than the signal strength of the first cell. When the detected signal strength of the second cell is less than the threshold, or the detected signal strengths of all second cells are less than the signal strength of the first cell, the UE accesses the first cell;

[0080] Specifically, when the network pages the UE, the base station sends a paging message within the super cell, and the idle UE only monitors paging within the super cell range. After receiving the paging cell sent by the super cell, the idle UE starts searching for nearby small cells and selects the small cell with the best downlink signal for access after there is a need to access the network. Alternatively, when the idle UE has uplink data transmission, it starts searching for nearby small cells and selects the small cell with the best downlink signal for access. The idle UE does not need to perform cell switching within each small cell within the super cell range, nor does it need to synchronously track the small cells, nor does it need to obtain system messages from the small cells. In this way, the power consumption of the UE can be reduced, and at the same time, paging the same UE in multiple small cells can be avoided, reducing the waste of downlink network resources. When the signal strength of the detected small cell is less than the threshold, or the signal strength of all detected small cells is less than the signal strength of the super cell, the UE accesses the super cell;

[0081] In one embodiment, detecting the sub-signal of the second cell includes: searching for the sub-signal of the second cell at a time-frequency position of the sub-signal corresponding to the second cell, wherein the time-frequency position of the sub-signal corresponding to the second cell is indicated by the time-frequency position information of the sub-signal of the second cell in the sub-signal configuration information of the second cell.

[0082] In one embodiment, detecting the sub-signal of the second cell includes: detecting the sub-signal of the second cell at a preset time-frequency position, wherein the preset time-frequency position includes one or more of the following methods: a preset fixed time-frequency position, a preset offset relative to the SSB time-frequency position of the first cell.

[0083] In an embodiment, the second cell sub-signal configuration information further includes: second cell corresponding sub-signal sequence information, wherein the second cell corresponding sub-signal sequence information is used to generate the second cell sub-signal.

[0084] In this embodiment, sub-signal time-frequency position information and sub-signal sequence information corresponding to each small cell are configured for the small cell; all small cells under the super cell may also share the same small cell sub-signal configuration, such as: all small cells under the super cell share the same time-frequency position, different small cells correspond to different sub-signal sequences, and the sub-signal sequence set may be predefined or indicated by the small cell configuration information.

[0085] The sub-signal is used for at least one of small cell discovery, small cell measurement, and small cell system message demodulation.

[0086] In one embodiment, before accessing the second cell, it also includes: determining an accessible second cell based on the second cell access control information, wherein the second cell access control information is carried by the first cell system message and / or by the second cell system message.

[0087] In one embodiment, after accessing the second cell based on the second cell configuration information, it also includes: after the connected wireless link fails or the cell reselection is triggered or the cell switching is triggered, when the second cell system message does not include the cell list information, selecting the cell access based on the cell list in the first cell system message; or when the second cell system message does not include the cell list information, accessing the first cell.

[0088] In one embodiment, after accessing the second cell based on the second cell configuration information, it also includes: after the connected wireless link fails or the cell reselection is triggered or the cell switching is triggered, selecting to access the second cell or the first cell based on the cell list information in the second cell system message, wherein the cell list information includes the second cell list information and / or the first cell list information.

[0089] In one embodiment, accessing the second cell based on the second cell system message includes: when the second cell configuration information includes second cell access configuration information, sending an access signal or access data based on the second cell access configuration information to access the second cell.

[0090] In one embodiment, the second cell access configuration information includes one or more of the following: time-frequency position information of the access signal, sequence information of the access signal, time-frequency position information of the access data, reference signal information of the access data, and downlink control information configuration information corresponding to the access response message.

[0091] In this embodiment, the reference signal information of the access data includes: a sequence identifier and reference signal pattern information, wherein the sequence identifier is used to generate a sequence of the reference signal. The sequence identifier is a sequence ID.

[0092] In this embodiment, the reference signal pattern information includes a first pattern and a second pattern, wherein the first pattern and the second pattern satisfy one or more of the following conditions: the interval of the time domain OFDM symbols corresponding to the reference signal of the first pattern is smaller than the time domain interval of the time domain OFDM symbols corresponding to the reference signal of the second pattern; the subcarrier interval of the frequency domain corresponding to the reference signal of the first pattern is smaller than the subcarrier interval of the frequency domain corresponding to the reference signal of the second pattern.

[0093] Specifically, the interval of the time domain OFDM symbols where the reference signal corresponds to the first pattern is smaller than the time domain interval of the time domain OFDM symbols where the reference signal corresponds to the second pattern. It can be understood that the time domain density of the first pattern is smaller than the time domain density of the second pattern. For example, the first pattern is a time domain OFDM symbol with a reference signal every 2 OFDM symbols, and the second pattern is a time domain OFDM symbol with a reference signal every 6 OFDM symbols.

[0094] Specifically, the subcarrier spacing in the frequency domain where the reference signal corresponding to the first pattern is located is smaller than the subcarrier spacing in the frequency domain where the reference signal corresponding to the second pattern is located. It can be understood that the frequency domain density of the first pattern is smaller than the frequency domain density of the second pattern, such as: the first pattern has a reference signal symbol every 1 subcarrier spacing, and the second pattern has a reference signal symbol every 3 subcarrier spacings.

[0095] In this implementation, the configuration information of the downlink control channel corresponding to the access response message includes the search space time-frequency position of the downlink control channel corresponding to the access response message, the mapping position of the downlink control channel corresponding to the access response message, the candidate set size of the downlink control channel corresponding to the access response message, the aggregation level information of the downlink control channel corresponding to the access response message, etc. The downlink control information includes the scheduling information of the data channel carrying the paging message, such as: the time-frequency position information of the data channel, the coding and modulation information of the data channel, etc.

[0097] In one embodiment, the method further includes: when the first node is in an idle state or an inactive state, the first node performs cell selection based on the signal strength of the first cell.

[0098] In one embodiment, the method further includes: when the first node is in an idle state or an inactive state, if cell reselection is triggered or cell switching is triggered, the first node performs cell selection based on first cell information in the cell list information in the first cell system message.

[0110] In one embodiment, the time-frequency position of the predefined search space includes one or more of the following modes: a preset fixed time-frequency position, a preset offset relative to the SSB time-frequency position of the first cell, and a preset offset relative to the sub-signal time-frequency position.

[0111] When the first cell includes access configuration information of the second cell, when no UE resides in the second cell, the second cell (third node) may only send a sub-signal, not send other signals and data, and be in an energy-saving state. The second cell detects an access signal or channel on the access resource configured by the first cell. If the access signal or channel is detected (the signal strength is detected to exceed a threshold, or the channel is successfully decoded), the second cell sends an access response message;

[0112] The access response message includes the resource location information of the UE sending the uplink data. Then, the second cell receives the uplink data sent by the UE and sends the UE specific configuration information and / or successful access indication information to the UE;

[0113] or,

[0114] The access response message includes the resource location information of the UE sending the uplink data and the successful access indication information. Then, the second cell receives the uplink data sent by the UE and sends the UE-specific configuration information to the UE;

[0115] or,

[0116] The access response message includes UE-specific configuration information and successful access indication information. The UE detects the UE-specific search space according to the specific configuration, and receives downlink data or sends uplink data.

[0117] In one embodiment, the base station of the super cell sends SSB and system messages of the super cell; the UE obtains the system messages of the super cell; the idle UE performs downlink synchronization, downlink measurement, and paging detection according to the SSB of the super cell and the system messages of the super cell; when the downlink measurement value meets the cell switching trigger condition, the super cell is reselected or switched. The idle UE does not select a small cell when switching or reselecting a cell;

[0118] The system message of the super cell includes access configuration information of the super cell, paging configuration information, small cell configuration information, access control information of the super cell, and neighboring cell list information of the super cell.

[0119] The small cell configuration information includes small cell list information, and the small cell list information includes small cell ID information, that is, sub-signal sequence information, wherein the small cell ID information is used to generate a sub-signal of the small cell.

[0120] Specifically, the idle UE performs detection on the downlink control channel search space corresponding to the paging message sent in the super cell system message configuration. When the downlink control channel is detected, it receives the downlink data channel according to the downlink control information carried by the downlink control channel, and confirms whether it has its own paging message according to the information carried by the downlink data channel; if it does not have its own paging message, it continues to perform paging detection.

[0121] When there is its own paging message, and the paging message is used for downlink data arrival or uplink data transmission, the UE searches for the sub-signal of the small cell at a predefined time-frequency position according to the small cell configuration information in the system message of the super cell, and selects the small cell with the strongest sub-signal for access, or selects any one of the small cells whose sub-signal strength exceeds the threshold for access, or compares the sub-signal strength of the small cell with the signal strength of the super cell, and selects a small cell with a stronger signal strength than the super cell for access. If there is no small cell with a stronger signal strength than the super cell, the UE selects the super cell for access.

[0122] The predefined time-frequency position for sending the small cell sub-signal may be a fixed time-frequency position, or may be a predefined offset relative to the super small cell SSB.

[0123] The threshold corresponding to the small cell sub-signal is configured by signaling, and the signaling is included in the system message of the super cell; the signaling can be configured for each small cell, or all small cells can use the same threshold; the threshold can be an absolute value, or an offset value relative to the downlink signal strength of the super cell, or a threshold offset value for super cell reselection.

[0124] In one embodiment, a method for UE to access a small cell is provided.

[0125] Mode 1: The UE detects the first system message of the small cell on a predefined time-frequency resource, or the UE detects the first system message of the small cell on a time-frequency resource with a predefined offset relative to the time-frequency position of the sub-signal; after obtaining the first system message, the UE detects the downlink control channel corresponding to the second system message on the second system message search space configuration indicated by the first system message, obtains the second system message according to the downlink control channel, and accesses the small cell according to the second system message; the second system message includes an access message of the small cell. The first system message may be a system message (MIB) carried by a physical broadcast channel, and the second system message is a system message (SIB) carried by a physical downlink shared channel.

[0126] Mode 2: The UE detects the downlink control channel corresponding to the small cell system message in the predefined search space, obtains the small cell system message according to the downlink control channel, and accesses the small cell according to the small cell system message; the small cell system message includes the access message of the small cell. The system message refers to the system message carried by the physical downlink shared channel.

[0127] The time-frequency position of the predefined search space may be a fixed time-frequency position, or a predefined offset relative to the time-frequency position of the super small cell SSB, or a predefined offset relative to the time-frequency position of the small cell subsignal.

[0128] In one embodiment, the base station of the super cell sends an SSB and a system message of the super cell; the UE obtains the system message of the super cell; the idle UE performs downlink synchronization, downlink measurement, and paging detection according to the SSB of the super cell and the system message of the super cell; when the downlink measurement value meets the cell switching trigger condition, the super cell is reselected or switched.

[0129] The system message of the super cell includes super cell access configuration information, paging configuration information, small cell configuration information, super cell access control information, and super cell neighbor list information.

[0130] The small cell configuration information includes the small cell list information; the small cell list information includes the small cell ID information (sub-signal sequence information) and the sub-signal time-frequency position information (specific time-frequency position or small cell frequency point information). The small cell ID information (sub-signal sequence information) is used to generate the sub-signal of the small cell.

[0131] Specifically, the idle UE performs detection on the downlink control channel search space corresponding to the paging message sent in the super cell system message configuration. When the downlink control channel is detected, it receives the downlink data channel according to the downlink control information carried by the downlink control channel, and confirms whether it has its own paging message according to the information carried by the downlink data channel; if it does not have its own paging message, it continues to perform paging detection.

[0132] When there is its own paging message, and the paging message is used for downlink data arrival or uplink data transmission, the UE searches for the sub-signal of the small cell at the sub-signal time-frequency position (specific time-frequency position or small cell frequency point) indicated by the small cell configuration information in the system message of the super cell, and selects the small cell with the strongest sub-signal for access, or selects any one of the small cells whose sub-signal strength exceeds the threshold for access, or compares the sub-signal strength of the small cell with the strength of the super cell signal, and selects a small cell with a stronger signal strength than the super cell for access. If there is no small cell with a stronger signal strength than the super cell, the UE selects the super cell for access.

[0133] The way in which the UE accesses the small cell may refer to the access method provided in the above embodiment, which will not be described in detail in this embodiment.

[0134] In one embodiment, the base station of the super cell sends an SSB and a system message of the super cell; the UE obtains the system message of the super cell; the idle UE performs downlink synchronization, downlink measurement, and paging detection according to the SSB of the super cell and the system message of the super cell; when the downlink measurement value meets the cell switching trigger condition, the super cell is reselected or switched.

[0135] The system message of the super cell includes access configuration information, paging configuration information, access control information of the super cell, and neighbor list information of the super cell.

[0136] Specifically, the idle UE performs detection on the downlink control channel search space corresponding to the paging message sent in the super cell system message configuration. When the downlink control channel is detected, it receives the downlink data channel according to the downlink control information carried by the downlink control channel, and confirms whether it has its own paging message according to the information carried by the downlink data channel; if it does not have its own paging message, it continues to perform paging detection.

[0137] When there is its own paging message and the paging message is used for downlink data arrival or uplink data transmission, the UE searches for the sub-signal of the small cell at a predefined time-frequency position, where the sub-signal is generated by a predefined sequence set. The UE detects multiple sub-signals and selects the small cell with the strongest sub-signal for access, or selects any one of the small cell set whose sub-signal strength exceeds a threshold for access, or compares the sub-signal strength of the small cell with the signal strength of the super cell, and selects a small cell with a signal strength greater than that of the super cell for access. If there is no small cell with a signal strength greater than that of the super cell, the UE selects the super cell for access.

[0138] The predefined time-frequency position for sending the small cell sub-signal may be a fixed time-frequency position, or may be a predefined offset relative to the super small cell SSB.

[0139] The way in which the UE accesses the small cell may refer to the access method provided in the above embodiment, which will not be described in detail in this embodiment.

[0140] In one embodiment, the base station of the super cell sends an SSB and a system message of the super cell; the UE obtains the system message of the super cell; the idle UE performs downlink synchronization, downlink measurement, and paging detection according to the SSB of the super cell and the system message of the super cell; when the downlink measurement value meets the cell switching trigger condition, the super cell is reselected or switched.

[0141] The system message of the super cell includes access configuration information, paging configuration information, small cell configuration information, access control information of the super cell, and neighbor list information of the super cell; and the small cell configuration information includes configuration information of the small cell system message.

[0142] The small cell system message configuration information includes configuring the downlink control information configuration corresponding to the small cell system message for each small cell (such as: search space time-frequency position, mapping method, candidate set size, aggregation level information, etc.); or, the small cell system message configuration information includes: all small cells under the super cell share the same system message configuration information, and all small cells share the same downlink control information search space.

[0143] When an idle UE has a need to access a cell (such as receiving its own paging message and the paging message is used to indicate the arrival of downlink data, or there is uplink data transmission), the UE detects a downlink control channel corresponding to the small cell system message in the small cell system message search space configured by the super cell system message, and when detecting the downlink control channel, receives the system message of the small cell according to the downlink control information carried by the downlink control channel, and accesses the small cell according to the system message of the small cell; wherein the system message of the small cell includes a small cell access message.

[0144] If the UE detects system messages of multiple small cells, the UE detects the signal strengths of the multiple small cells according to the system messages, selects the small cell with the strongest signal for access, or randomly selects one of the small cell set whose signal strength exceeds a threshold for access, or compares the signal strength of the small cell with the signal strength of the super cell, and selects a small cell with a greater signal strength than the super cell for access; if there is no small cell with a greater signal strength than the super cell, the UE selects the super cell for access.

[0145] The way in which the UE accesses the small cell may refer to the access method provided in the above embodiment, which will not be described in detail in this embodiment.

[0146] In one embodiment, the base station of the super cell sends SSB and system messages of the super cell; the UE obtains the system messages of the super cell; the idle UE performs downlink synchronization, downlink measurement, and paging detection according to the SSB of the super cell and the system messages of the super cell; when the downlink measurement value meets the cell switching trigger condition, the super cell is reselected and switched. After the idle UE resides in the super cell, during the UE mobility process (cell switching process), the idle UE does not select small cell measurement, nor does it select small cell to reside, nor does it obtain the system messages of the small cell, nor does it monitor the paging messages sent by the small cell (the system messages of the small cell do not include the small cell paging configuration information).

[0147] The system message of the super cell includes access configuration information, paging configuration information, small cell configuration information, access control information of the super cell, and neighbor list information of the super cell; the small cell configuration information includes configuration information of the small cell system message and small cell list information.

[0148] Among them, small cell list information; the small cell list information includes small cell ID information (sub-signal sequence information) and time-frequency position information of the sub-signal (specific time-frequency position or small cell frequency point information); the small cell ID information (sub-signal sequence information) is used to generate the sub-signal of the small cell.

[0149] The idle UE performs detection on the downlink control channel search space corresponding to the paging message sent in the super cell system message configuration. After detecting the downlink control channel, it receives the downlink data channel according to the downlink control information carried by the downlink control channel, and confirms whether it has its own paging message according to the information carried by the downlink data channel; if it does not have its own paging message, it continues to perform paging detection.

[0150] When there is its own paging message and the paging message is used for downlink data arrival (or uplink data transmission), the UE searches for the sub-signal of the small cell (generated according to the small cell ID information) at the sub-signal time-frequency position (specific time-frequency position or small cell frequency point) indicated by the small cell configuration information in the system message of the super cell, and selects the small cell with the strongest sub-signal for access, or selects any one of the small cells with sub-signal strength exceeding the threshold for access, or compares the sub-signal strength of the small cell with the strength of the super cell signal, and selects the small cell with greater signal strength than the super cell for access; if there is no small cell with greater signal strength than the super cell, the UE selects the super cell for access.

[0151] According to the small cell selected above, the configuration information of the selected small cell is obtained in the small cell configuration information of the super cell system message, and the UE detects the downlink control channel corresponding to the small cell system message in the small cell system message search space configured in the super cell system message. When the downlink control channel is detected, the system message of the small cell is received according to the downlink control information carried by the downlink control channel, and the small cell is accessed according to the system message of the small cell; wherein the system message of the small cell includes a small cell access message.

[0152] The way in which the UE accesses the small cell may refer to the access method provided in the above embodiment, which will not be described in detail in this embodiment.

[0153] For the above embodiment, when the small cell system message includes the small cell access control information, the UE needs to determine whether it can access the small cell before accessing the small cell; or, the small cell access control information is included in the system message of the super cell, and the UE confirms the accessible small cell according to the small cell access control information or the small cell list in the system message of the super cell, and selects the accessible small cell sub-signal for detection; or, the small cell access control information may also be included in the system message of the super cell, and the UE confirms the accessible small cell according to the small cell access control information or the small cell list in the system message of the super cell, and selects the downlink control channel detection corresponding to the system message of the accessible small cell for detection.

[0154] For the above embodiment, the system message of the small cell sent by the small cell only includes the neighboring cell list information of the small cell; after the connected radio link fails or the cell reselection is triggered or the cell switching is triggered, the UE selects the small cell to reside, switch or access according to the adjacent small cell information in the system message of the small cell; when there is no neighboring cell list information, the UE selects the super cell to measure according to the super cell list in the super cell system message, selects the super cell to reside, switch or access, or the UE continues to re-access in the small cell, or selects the super cell where the small cell is located to reside, switch or access, or, if the signal strength of the small cell is less than the threshold, then according to the super cell list information in the system message of the small cell, selects the super cell to access the network.

[0155] or,

[0156] The system message of the cell includes the neighboring cell list information and the super cell list of the small cell; after the wireless link in the connected state fails or the cell reselection is triggered or the cell handover is triggered, the UE selects the small cell to reside in, switch to or access according to the small cell information in the system message of the small cell. If the signal strength of all small cells is less than the threshold, the UE selects the super cell in the super cell list to reside in, switch to or access. Alternatively, according to the small cell information and super cell information in the system message of the small cell, the small cell and the super cell are measured, and the cell with the highest signal strength is selected to reside in, switch to or access.

[0157] or,

[0158] The system message of the small cell only includes the neighboring cell list information of the super cell; after the connected radio link fails or the cell reselection is triggered or the cell switching is triggered, the UE measures the super cell according to the super cell list information in the system message of the small cell, and selects the super cell to reside in, switch to, or access according to the measurement result; or, if the signal strength of the small cell is less than the threshold, the UE selects the super cell to reside in, switch to, or access according to the super cell list information in the system message of the small cell.

[0159] Under the above small cell structure, paging is further optimized.

[0160] After the UE enters the idle state from the connected state, the UE monitors the paging of the source small cell while it is in the source small cell (the small cell where it is in the connected state), and when the UE moves out of the source small cell, the UE monitors the paging of the super cell; at this time, the small cell system message includes the configuration information of the small cell paging; or, after the UE enters the idle state from the connected state, the UE monitors the paging of the source small cell and the super cell while it is in the source small cell (the small cell where it is in the connected state), and when the UE moves out of the source small cell, the UE only monitors the paging of the super cell; at this time, the small cell system message includes the configuration information of the small cell paging. Or, after the UE enters the idle state from the connected state, the UE only monitors the paging of the super cell, and at this time, the small cell system message does not include the configuration information of the small cell paging, and the small cell system message includes the configuration information of the super cell paging, and the UE monitors according to the super cell paging configuration information.

[0161] The base station first pages the UE on the source small cell. If the UE is not paged, it will page the UE within the range of the super cell.

[0162] The above idle state also includes the inactive state newly added by 5G NR, as well as other new non-connected states added to future networks.

[0163] The solutions in all the above embodiments are also applied to multi-cell joint networking, and high- and low-frequency joint networking scenarios.

[0164] The super cell transmits SSB and super cell SI (including existing cell SI and newly added small cell configuration SI), that is, small cells within a certain range or area share the same downlink synchronization channel, have the same subframe synchronization and frame synchronization, and the small cell has its own sub-ID (generates discovery signal) and dedicated system message (distributed SI). UE can access on the exclusive access resources configured by each small cell SI. When the network pages the UE, the base station sends a paging message in the super cell. The idle UE only listens to the paging message sent by the super cell. After receiving the paging cell sent by the super cell, the idle UE starts to search for the nearby small cell discovery signal and selects the small cell with the best downlink signal strength to access. Or, when the idle UE has uplink data transmission, it starts to search for the nearby small cell and selects the small cell with the best downlink signal strength to access. When the UE accesses the small cell, downlink synchronization and uplink path loss estimation are performed according to the small cell discovery signal. After access, UE specific RRC can also be configured with UE-specific parameters to realize virtual cells. The idle UE does not need to perform cell switching in each small cell within the super cell range, nor does it need to synchronize and track the small cell, nor does it need to obtain the system message of the small cell. In this way, the power consumption of the UE can be reduced, and at the same time, it also avoids paging the same UE in multiple small cells, reducing the waste of downlink network resources. At the same time, the small cell can only send a small amount of discovery signals and distributed SI to achieve base station energy saving.

[0165] The super cell and the small cell may be at the same frequency or at different frequencies, such as a super cell at a low frequency and a small cell at a high frequency. The super cell and the small cell may belong to the same wireless system, such as both belong to the 5G system, or both belong to the 6G system or a future network. They may also belong to different wireless systems, such as a super cell belongs to the 4G system and the small cell belongs to the 5G system, or a super cell belongs to the 4G system or the 5G system and the small cell belongs to the 6G system or a future network.

[0166] When the super cell and the small cell belong to different frequencies, the system message of the super cell may include the frequency information of the small cell.

[0167] If the time of the super cell and the small cell are not synchronized, the system message of the super cell may further include offset information of subframes / radio frames / symbols of the super cell and the small cell.

[0168] When the super cell and the small cell belong to different wireless systems, the system message of the super cell may include the frequency information and wireless system type information of the small cell.

[0184] However, for a connection mode UE of the CP solution, if the UE does not use PUR resources during the connection establishment process, the base station cannot know whether the UE is configured with PUR resources, or cannot know the PUR resource information configured for the UE.

[0185] To this end, this embodiment provides a method for a base station to obtain PUR configuration information of a UE in a connected mode of a CP scheme, which is used for maintaining CP-PUR resources on the base station side. Figure 7 As shown, it mainly includes the following steps:
