Description

Cell access method, communication device and storage medium

Technical Field

The present disclosure relates to the field of communications, and in particular, to a cell access method, a communication device, and a storage medium.

Background

In a communication system, a base station is a key node connecting user equipment and a communication network. With the wide application of technologies such as large-scale antennas and large bandwidths, the energy consumption problem of the base station is gradually highlighted. To solve this problem, green communication and base station power saving technologies are hot spots of research. Wherein, reducing the transmission of common signals/signaling (e.g., system information block (system information block, SIB) information) of the base station, and entering the base station into a sleep state when the base station does not need to transmit signals/signaling, can save the energy consumption of the base station. Based on the above approach to saving energy consumption of base stations, some base stations may choose not to send common signals/signaling (e.g., SIB information) to achieve network power savings.

However, when a communication node (e.g., a terminal) accesses a base station (e.g., a cell covered by the access base station), it is generally necessary to receive SIB information (e.g., system information block type 1 (system information block, sib1) information) on the cell to perform access based on network parameters, configuration information, etc. in the SIB information. For realizing network energy saving, selecting a cell which does not send SIB information may make the communication node unable to access the cell, thereby affecting normal access of the communication node.

The network architecture of the communication network (including but not limited to 3g,4g,5g, and future mobile communication networks) in embodiments of the present disclosure may include at least a first node and a second node. In this example, the first node may be a terminal-side device (e.g., including but not limited to a terminal) and the second node may be a network-side device (e.g., including but not limited to a base station).

An exemplary communication system provided by the embodiments of the present disclosure is shown in fig. 1, where a first node is a terminal and a second node is a base station. The communication system includes a terminal 110 and a base station 120. Wherein the terminal 110 is communicatively coupled to the base station 120.

In some embodiments, the base station 120 may be one or more, and the terminal 110 may be one or more, and the embodiments of the present disclosure are not limited in number.

The terminal 110 may determine a target cell to be accessed, and access the target cell based on configuration information of access resources of the target cell.

In some embodiments, the configuration information of the access resources includes Physical Random Access Channel (PRACH) resource information, or an adaptive configuration of the access resources. For example, the adaptive configuration information of the access resource includes a period configuration, a multi-set access resource configuration, and a configuration using different access resources in different periods. Wherein the access resources may be dynamically changed according to the period.

In some embodiments, the terminal 110 may receive access information, such as SIB information, broadcast by the base station 120, determine configuration information of access resources of the first type cell based on the SIB information, and then access the target cell.

Illustratively, the terminal 110 may receive access information on a first type of cell. Wherein the access information comprises configuration information of access resources of a second type of cell associated with the first type of cell. The second type of cell associated with the first type of cell includes a target cell. At this time, the terminal 110 may access the target cell based on the configuration information of the access resource of the second type cell in the access information.

In some embodiments, the terminal 110 receives the access information transmitted by the base station 120 and accesses the target cell according to the access information.

In some embodiments, the terminal 110 may also send the first signaling to the base station 120 and receive the second signaling of the base station 120 in response to the first signaling to determine configuration information of access resources of the target cell based on the second signaling and access the target cell.

In some embodiments, the second signaling may indicate access resource indices in the adaptive configuration of access resources, each access resource index corresponding to a set of access resources.

By way of example, the terminal may be a mobile phone, a tablet (Pad), a computer with wireless transceiving functionality, a Virtual Reality (VR) terminal, an augmented Reality (Augmented Reality, AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned (SELF DRIVING), a wireless terminal in telemedicine (remote medical), a wireless terminal in smart grid (SMART GRID), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (SMART CITY), a wireless terminal in smart home (smart home), and so forth. Embodiments of the present disclosure are not limited to application scenarios. A terminal may also be referred to as a user, user Equipment (UE), access terminal, UE unit, UE station, mobile station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent, UE device, or the like, as embodiments of the present disclosure are not limited in this respect.

The base station 120 is configured to receive a signaling issued by the core network, and broadcast and send the signaling according to a configuration in the signaling.

In some embodiments, the coverage area of the base station 120 includes at least one cell. Illustratively, the coverage area of the base station 120 includes a first type of cell and a second type of cell. The base station 120 may transmit access information on a first type of cell and/or transmit access information on a second type of cell. The first type cell may be an anchor cell, and the second type cell may be a non-anchor cell.

It should be noted that some Network ENERGY SAVING (NES) operations, such as SIB-less operations, may be used or performed on the non-anchor cells. Based on the SIB-less operation, the base station 120 does not transmit SIB1 or SIB on the non-anchor cell; or no SIB1 or no SIB on the non-anchor cell; or lack SIB1 or SIB on the non-anchor cell. When SIB-less is used on the non-anchor cell, SIB information of the non-anchor cell may be received on the anchor cell, i.e., base station 120 may transmit SIB information of the non-anchor cell on the anchor cell.

It should be noted that, in the embodiments of the present disclosure, the anchor cell or the non-anchor cell or the first type cell or the second type cell may represent not only one cell but also one or more frequency domain resources, for example, one or more carriers, one or more bandwidths, one or more bandwidth portions, one or more frequency bands, and so on.

Illustratively, the anchor cell may be a primary cell and the non-anchor cell may be a secondary cell. Or the anchor cell may be one carrier and the non-anchor cell may be another carrier. Or the anchor cell may be one set of carriers and the non-anchor cell may be another set of carriers. Or the anchor cell may be one bandwidth and the non-anchor cell may be another bandwidth. Or the anchor cell may be one bandwidth portion and the non-anchor cell may be another bandwidth portion. Or the anchor cell may be one set of bandwidths and the non-anchor cell may be another set of bandwidths. The embodiments of the present disclosure are not limited in this regard. For ease of description and uniformity, the following description will be given in terms of cells.

In some embodiments, the first type of cell is a cell that the terminal has camped on before camping on the second type of cell.

In some embodiments, the coverage areas of the first type of cell and the second type of cell overlap.

In some embodiments, the first type of cell is one set of carriers and the second type of cell is another set of carriers, the difference in frequency points of the two sets of carriers not exceeding a first threshold. Illustratively, the first threshold is greater than or equal to 0 and less than or equal to 1GHz, 2GHz, 3Ghz, 4GHz, or 5GHz.

In some embodiments, the first type of cell is one set of bandwidths and the second type of cell is another set of bandwidths, the difference in frequency points of the two sets of bandwidths not exceeding a second threshold. Illustratively, the second threshold is greater than or equal to 0 and less than or equal to 1GHz, 2GHz, 3Ghz, 4GHz, or 5GHz.

In some embodiments, when the terminal has a need to access the target cell, the base station 120 may also send a second signaling to the terminal 110 on the target cell or a first type of cell associated with the target cell after receiving the first signaling of the terminal 110. The first signaling is used for requesting configuration information of access resources of the target cell. The second signaling includes configuration information of access resources of the target cell.

In some embodiments, the first signaling is an uplink wake-up signaling, e.g., wake-up signal (WUS) signaling.

In some embodiments, the base station may be a long term evolution (long term evolution, LTE), a base station or evolved base station (evolutional node B, eNB or eNodeB) in long term evolution enhancement (long term evolution advanced, LTEA), a base station device in a 5G network, or a base station in a future communication system, etc., which may include various macro base stations, micro base stations, home base stations, wireless remotes, reconfigurable intelligent surfaces (reconfigurable intelligent surfaces, RISs), routers, relays, wireless fidelity (WIRELESS FIDELITY, WIFI) devices, etc., and various network side devices.

It should be noted that, the above scenario is for more clearly describing the technical solution of the embodiments of the present disclosure, and does not constitute a limitation to the technical solution provided by the embodiments of the present disclosure, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present disclosure is equally applicable to similar technical problems.

In a communication system, a base station is a key node connecting user equipment and a communication network. With the wide application of technologies such as large-scale antennas and large bandwidths, the energy consumption problem of the base station is gradually highlighted. To solve this problem, green communication and base station power saving technologies are hot spots of research. Wherein, reducing the transmission of the public signal/signaling (for example, SIB information) of the base station, and entering the base station into the sleep state when the base station does not need to transmit the signal/signaling, can save the energy consumption of the base station. Based on the above approach to saving energy consumption of base stations, some base stations may choose not to send common signals/signaling (e.g., SIB information) to achieve network power savings. However, reducing the transmission of common signals/signaling may affect system performance, affect system capacity, etc. Thus, further investigation is needed as to which signals/signaling can reduce transmission and how to reduce or eliminate impact on the system.

Illustratively, when accessing a base station (e.g., a cell covered by the access base station), a terminal typically needs to receive SIB information, SIB1 information, other (other) SIB information, paging (paging) information, random ACCESS CHANNEL initiation random access channel information (RACH), etc. on the cell for access. However, for the non-anchor cell using SIB-less, the terminal cannot receive SIB information, so that the terminal cannot access the non-anchor cell, and the normal access of the terminal is affected.

In view of the foregoing, referring to fig. 2, a flowchart of a cell access method is provided in an embodiment of the disclosure. As shown in fig. 2, the cell access method provided by the embodiment of the present disclosure is applied to a first node, and includes the following steps:

S101, determining a target cell to be accessed.

In some embodiments, the types of cells may include a first type cell and a second type cell.

In some embodiments, the first type of cell is a cell that does not enable a power saving function. The second type of cell is a cell that enables a power saving function.

In some embodiments, the first type of cell is a cell that transmits SIB1 or SIB. The second type of cell is a cell that does not transmit SIB1 or SIB.

In some embodiments, the first type of cell may be referred to as an anchor cell and the second type of cell may be referred to as a non-anchor cell, without limitation.

In some embodiments, a first type of cell is associated with one or more second type of cells. The terminal may obtain access information for the first type cell and the second type cell on the first type cell. When a first node (e.g., a terminal) needs to access a target cell, the target cell to be accessed may be determined from a plurality of cells based on access information of the plurality of cells. For example, the first node may determine a target cell satisfying the current access scenario from among the plurality of cells based on signal strength, coverage, etc. in the access information of the plurality of cells.

In some embodiments, the access information may be indicated by one signaling, or by a plurality of different signaling. As an example, the access information includes configuration information of access resources of the first type cell and the second type cell, access parameters. The configuration information of the access resources of the first type cell and the second type cell is indicated by SIB1 or SIB of different cells, and the access parameters are indicated by SIB1 of the first type cell.

In some embodiments, the access parameters include at least one of: access weight, access priority, access selection mode, terminal Identification (ID), terminal group identification.

As one example, the access weight may be a priority of the first node to obtain resources when competing for limited wireless resources. When multiple first nodes request access to the wireless network at the same time, the base station needs to determine which first nodes can obtain higher priority and resource allocation according to a certain policy. The access weight may be used to distinguish and order the access requirements of the different first nodes. A higher access weight indicates that the first node has a higher access priority and can more easily obtain the resource allocation. Conversely, a lower access weight indicates a lower access priority for the first node, and less chance of resource acquisition is possible.

As another example, the access weight may also be a value used to calculate candidate cell priorities when selecting an access cell. For example, when there are multiple candidate cells, the measurement results of the candidate cells need to be multiplied by corresponding access weights, and the resulting values are used to select the final target cell. Wherein, the higher the value of the access weight, the higher the priority.

In some embodiments, different cells have different access weights.

In some embodiments, a cell may have multiple access weights corresponding to different bandwidths or carriers or bands of the cell.

In some embodiments, the access weight is related to candidate cell priority.

The access selection mode refers to a method and a strategy for the first node to access. The access selection manner may be, for example: a random access method, a frequency division multiplexing method, an access method based on signal quality, selecting a target cell based on a measurement result or a threshold, selecting a target cell based on a signaling instruction, selecting a target cell based on an access parameter, and the like. Different access selection manners may be used alone or in combination, and embodiments of the present disclosure are not limited in this regard.

As another example, the access information includes configuration information of access resources of the first type cell and the second type cell, and an indication of the second type cell associated with the first type cell. The configuration information of the access resources of the first type cell and the second type cell is indicated by SIB1 of different cells. In some embodiments, the indication of the second type of cell associated with the first type of cell is indicated by signaling in core network or non-access stratum (NAS) signaling.

In some embodiments, the first node may identify the first type of cell and the second type of cell associated with the first type of cell based on different ways. As one example, the base station may not transmit information (e.g., SIB1 information) on the second type of cell, and the first node may receive information (e.g., SIB1 information or master information block (master information block, MIB) information) of the first type of cell on the first type of cell, as well as information of one or more second type of cells. Illustratively, the information of the first type cell is configured with an ID or PCI of the second type cell associated with the first type cell. Wherein the ID or PCI of the second type of cell associated with the first type of cell is in a list. Or the information of the first type cell is configured with an identification ID or a physical cell identification code (PHYSICAL CELL IDENTIFIER, PCI) of a second type cell associated with the first type cell. Wherein an ID or PCI of a second type cell associated with the first type cell is associated with configuration information of access resources of the second type cell.

As another example, the first node may obtain an indication of the first type of cell and the second type of cell associated with the first type of cell through core network signaling or NAS signaling. For example, the signaling of the core network may indicate whether a cell is a first type cell or a second type cell. For cells of the second type, there is core network signaling indicating the cells of the first type with which it is associated. Or for a first type of cell, there is a core network signaling indicating a second type of cell associated therewith.

As yet another example, the association of the first type of cell with the second type of cell is predefined. For example, the association may be based on the cell ID or PCI. For example, one or more cells having a specific ID or PCI may be predefined as a first type cell or a second type cell.

S102, accessing the target cell based on the configuration information of the access resource of the target cell.

In some embodiments, after the first node determines the target cell to be accessed, configuration information of access resources of the target cell needs to be acquired to access the target cell. Illustratively, the configuration information for the access resource includes at least one of: the first node is configured to perform random access information, a location of a random access resource, and configuration information of a preamble (preamble). The first node may perform network setting and connection based on the above information, and then access the target cell.

As one example, the first node may send Msg1, msg3, or MsgA to the base station for initial access at the location of the random access resource.

As another example, the first node may receive Msg2, msg4, or MsgB transmitted by the base station at the location of the random access resource.

In some embodiments, the configuration information of the access resource may be information in SIB 1.

In some embodiments, the configuration information for each access resource is associated with one cell. For example, the configuration information for each/access resources may be associated with a cell identity of a cell, or with a PCI of a cell. Or the configuration information for each/access resource may be sent on different signaling (e.g., SIB 1) associated with different cells. Each cell has configuration information of corresponding access resources.

In some embodiments, the first node may also obtain a list of configuration information. Wherein the configuration information list includes configuration information of access resources of one or more non-anchor cells (for example, cells of a second type), the first node may determine a target cell from the non-anchor cells, and access the target cell.

In some embodiments, after the first node accesses the target cell, if the target cell is a non-anchor cell, the target cell is switched to an anchor cell. That is, SIB-less or power saving operation of the target cell is turned off, and the target cell is transferred to a normal cell.

In some embodiments, when the target cell accessed by the first node is a non-anchor cell, the access information of the target cell does not need to be sent on the first type cell associated with the non-anchor cell.

In some embodiments, the above method further comprises: access information is received on a first type of cell.

Wherein the access information includes configuration information of access resources of a second type cell (i.e., non-anchor cell) associated with the first type cell (i.e., anchor cell), the second type cell associated with the first type cell including the target cell.

In some embodiments, the access information further comprises at least one of:

Configuration information of access resources of the first type cell;

An indication of a second type of cell associated with the first type of cell;

An indication of cells allowed to access;

An indication of a cell to which access is denied;

access parameters.

In some embodiments, the specific content of the configuration information of the access resource of the first type cell may refer to the specific description of the configuration information of the access resource of the target cell, which is not described herein.

It can be understood that, based on the cell access method provided by the embodiment of the present disclosure, after determining the target cell to be accessed, the first node does not need to wait for the target cell to send a common signal/signaling (for example, SIB information) and then access, but can directly access the target cell based on configuration information of access resources of the target cell. The problem of access failure of the first node caused by waiting for the public signal/signaling is avoided, normal access of the first node is ensured, and the risk of access failure of the first node is reduced.

In some embodiments, as shown in fig. 3, the method further comprises: steps S201 to S202.

S201, receiving access information on a first type cell.

Wherein the access information (e.g., SIB1 information) includes configuration information of system information of a second type of cell associated with the first type of cell, the first type of cell or the second type of cell including the target cell.

In some embodiments, there is an indication of a second type of cell (i.e., a non-anchor cell associated with the anchor cell) on a first type of cell (i.e., the anchor cell). When the first node receives the access information on the first type cell, the first node may receive configuration information of access resources of the first type cell and configuration information of system information of the second type cell.

S202, receiving the system information of the target cell on the target cell based on the configuration information of the system information of the target cell.

The system information of the target cell comprises configuration information of access resources of the target cell.

In some embodiments, the first node may receive system information (for example SIB1 information) of the target cell, that is, configuration information of access resources of the target cell, on the target cell before accessing the target cell, so as to access the target cell.

In some embodiments, the periodicity of SIB1 information on the second type of cell is greater than the periodicity of SIB1 information on the first type of cell.

In some embodiments, the base station transmits configuration information of part of the access resources on the second type of cell.

In some embodiments, when the first node receives the configuration information of the access resource corresponding to the target cell, the first node receives SIB1 information corresponding to the target cell.

In some embodiments, the access information further comprises at least one of:

configuring reference signals of the second type cell;

The synchronous signal block configuration of the second type cell;

downlink carrier locations of the second type of cell;

downlink frequency points of the second type cell;

frequency points and/or carrier positions of an uplink WUS of the second type cell;

access parameters.

In some embodiments, the access information received on the first type cell is indicated by SIB1 of the first type cell and/or the second type cell.

In some embodiments, if the first node is instructed to prohibit/allow access cells, the first node can only select a target cell from the access-allowed cells for access.

It may be understood that, by receiving the access information on the first type cell and receiving the system information of the target cell on the target cell based on the configuration information of the system information of the target cell, the first node may obtain the relevant information of the target cell from the first type cell in time when the target cell does not send the common signal/signaling (e.g. the access information), so as to ensure the normal access of the first node.

In some embodiments, as shown in fig. 4, the method further comprises: steps S301-S302.

S301, transmitting a first signaling on a target cell or a first type of cell associated with the target cell.

The first signaling is used for requesting configuration information of access resources of the target cell.

In some embodiments, when there is access information on the first type cell, but the access information does not include configuration information of access resources of the second type cell (i.e., the target cell), the first node sends a first signaling to the base station to request configuration information of access resources of the target cell.

In some embodiments, the second type of cell is not associated with the first type of cell and there is no configuration information for access resources in the second type of cell, the first node may send a first signaling like a base station to request configuration information for access resources of the target cell.

In some embodiments, the first signaling is uplink wake-up signaling. Wherein the first signaling is sent on the first type of cell or the second type of cell to be accessed (i.e. the target cell).

As an example, the first signaling may be WUS signaling with low power consumption for waking up the base station, or requesting SIB1, or requesting a synchronization signal block (synchronization signal block, SSB), or requesting access resource information of the target cell.

As another example, the first signaling may be a preamble (initial access message Msg 1), where the preamble is a preamble of a first type cell, and the first node transmits the preamble on the first type cell, and the base station may determine what the first node wants to request. E.g. one or more predefined preambles, corresponding to different cells of the second type. The first node transmits a corresponding preamble representing configuration information for the first node requesting access resources of the corresponding second type cell.

As yet another example, the first signaling may be a preamble of a second type cell, the preamble of the second type cell being a predefined preamble, the preamble of the second type cell being access information. The first node may send a predefined preamble of the second type cell on the second type cell. The predefined preamble indicates configuration information that the first node requests access resources of the complete/all second type cells.

As yet another example, the first signaling may be an initial access message Msg3 of the first type cell, including configuration information in Msg3 requesting access resources of the second type cell.

As yet another example, the first signaling may be an initial access message MsgA for the first type cell.

In some embodiments, the transmission location of the first signaling is indicated in the access information. The access information includes SIB1 of the first type or the second type cell.

In some embodiments, the access information is indicated by signaling in the core network or NAS.

In some embodiments, the transmission location of the first signaling may also be predefined.

In some embodiments, the access information further comprises at least one of:

An indication of cells allowed to access;

An indication of a cell to which access is barred;

configuring reference signals of the second type cell;

The synchronous signal block configuration of the second type cell;

Accessing a measurement threshold;

Configuration information of system information of the second type cell.

In some embodiments, the access measurement thresholds are predefined and the access measurement thresholds for different cells may be different.

In some embodiments, the access information further comprises: and sending the uplink resource position of the first signaling and/or receiving the downlink resource position of the configuration information of the access resource.

S302, second signaling is received on the target cell or a first type of cell associated with the target cell.

Wherein the second signaling includes configuration information of access resources of the target cell.

In some embodiments, after the first node requests the configuration information of the access resource of the second type cell (i.e. the target cell), it needs to monitor (or receive) the signaling for a certain period of time, that is, receive the second signaling on the target cell or the first type cell, so as to access the target cell based on the configuration information of the access resource of the target cell in the second signaling. Wherein the second signaling indicates at least one of: cell ID, PCI, PCI list, cell ID list, whether a cell can be accessed.

In some embodiments, at least one of a second signaling SSB, MIB, paging downlink control information (paging downlink control information, PAGING DCI), paging, downlink physical shared channel (physical downlink SHARED CHANNEL, PDSCH), downlink physical indication information (physical downlink indicator, PEI), low power consumption (LP) WUS, system information-radio network temporary identifier (systeminformation-radio network temporary identifier, SI-RNTI) scrambled DCI, SIB.

In some embodiments, the content of the second signaling indication includes an index of access resources. In some embodiments, the second signaling indicates a time-frequency domain location of the content that includes the access resource. In some embodiments, the content of the second signaling indication includes a period of access to the resource. In some embodiments, the second signaling indicates a change value of the access resource. In some embodiments, the second signaling indicates a subcarrier spacing SCS of the access resource.

In some embodiments, the above method further comprises: receiving access information, the access information comprising: the transmission resource configuration of the first signaling and/or the transmission resource configuration of the second signaling.

It may be appreciated that, when the configuration information of the access resource of the target cell is not included in the access information of the first type cell, the first node may send the first signaling in time to request the configuration information of the access resource of the target cell, so that the first node may normally access the target cell and use the network service based on the configuration information of the access resource of the target cell. Or when the second type cell is not associated with the first type cell, the first node can timely send the first signaling to request the configuration information of the access resource of the target cell, so that the first node can normally access the target cell and use the network service based on the configuration information of the access resource of the target cell. In some embodiments, the second type of cell is not associated with the first type of cell, meaning the second type of cell, which is a separate cell, and the cell's related information is not transmitted on other cells.

In some embodiments, the first type of cell is a coverage cell.

In some embodiments, the second type cell is a SIB1-less cell, and the first node obtains uplink WUS related configuration information of the second type cell on the overlay cell (e.g., the first type cell) or an indication of the overlay cell (e.g., the first type cell) associated with the second type cell before camping on the second type cell. Illustratively, the configuration information related to the uplink WUS of the second type cell obtained by the first node on the overlay cell (e.g., the first type cell), or the indication of the overlay cell associated with the second type cell, is sent by the core network or NAS.

In some embodiments, the second type of cell is a separate cell, and the relevant information of the second type of cell (e.g., configuration information of the uplink WUS, etc.) is transmitted in the other cell, but the second type of cell is not associated with the cell that transmitted its relevant information (e.g., configuration information of the uplink WUS, etc.).

In some embodiments, the step S101 may be specifically implemented as: and determining a target cell according to the access information.

As a possible implementation manner, the determining the target cell according to the access information may be specifically implemented as follows: and selecting the cell with the best measurement result as a target cell. The measurement result may be used as an access information.

In some embodiments, the first node measures SSBs or reference signals of a first type of cell (i.e., anchor cell) and a second type of cell (i.e., non-anchor cell), and selects the cell with the best measurement or the highest measurement as the target cell.

As another possible implementation manner, the determining the target cell according to the access information, as shown in fig. 5, may be specifically implemented as follows: steps S401 to S402.

S401, determining candidate cells meeting preset conditions according to the measurement results of the cells and the access measurement threshold of the cells in the access information.

In some embodiments, the measurement threshold may be predefined.

In some embodiments, the preset conditions include at least one of:

the measurement result of the candidate cell is larger than or equal to the access measurement threshold of the candidate cell;

In case the candidate cell is a second type cell, the measurement result of the candidate cell is larger than the measurement result of the associated first type cell;

In case the candidate cell is a second type cell, a difference between the measurement result of the candidate cell and the measurement result of the associated first type cell is greater than a first threshold;

In the case that the candidate cell is a second type cell, the measurement result of the candidate cell is greater than a second threshold, the measurement result of the associated first type cell is greater than a third threshold, and the second threshold is greater than or equal to the third threshold.

In some embodiments, the access measurement threshold of the first type of cell is different from the access measurement threshold of the second type of cell.

In some embodiments, the access measurement threshold of the first type of cell is less than or equal to the access measurement threshold of the second type of cell.

It can be understood that the second type cell (i.e. the non-anchor cell) is an energy-saving cell, and the first node can access the second type cell only when the measurement result of the second type cell is good, and switch the second type cell to a normal cell. The access measurement threshold of the first type cell is smaller than or equal to the access measurement threshold of the second type cell, so that the state of the second type cell can be ensured to be switched only when the measurement result of the second type cell is very good, and frequent state switching of the second type cell is avoided.

In some embodiments, access measurement thresholds are indicated in a list, each access measurement threshold being associated with one or more cells of the first type/cells of the second type.

As an example, the association may be: each row of the list includes both the access measurement threshold and the PCI of the second type cell. As another example, the association may be: the access measurement threshold in the list corresponds to the PCI of the cell from small to large according to index from small to large. Wherein the cells include cells of a first type and cells of a second type associated with the cells of the first type.

In some embodiments, the PCI of each cell in the access information is associated with an access measurement threshold.

S402, determining a target cell from the candidate cells.

In some embodiments, determining the target cell from the candidate cells includes at least one of:

selecting a cell with the best measurement result or highest measurement value from the candidate cells as a target cell;

Selecting a cell with the largest difference between a measurement result in the candidate cell and an access measurement threshold as a target cell;

the first node randomly selects a cell from the candidate cells as a target cell.

In some embodiments, the candidate cell has only one cell, and the cell is the target cell.

In some embodiments, the above determination of the target cell from the candidate cells may be further implemented as: determining a target cell from the candidate cells according to the received third signaling; and/or determining the target cell from the candidate cells according to at least one of the terminal identification, the cell identification, the physical cell identification, the terminal type, the service type, the number of access resources of the cell and the access parameters.

In some embodiments, the third signaling includes at least one of: the method comprises the steps of identifying a target cell, identifying a physical cell of the target cell, identifying a list of the target cell, identifying the physical cell of the target cell, and indicating whether to access the cell. The first node may determine the target cell that may be accessed based on the indication of the third signaling.

In some embodiments, the third signaling is indicated by at least one of SSB, MIB, DCI (e.g., paging DCI or SI-RNTI scrambled DCI), PDSCH (e.g., paging PDSCH), PEI, LP-WUS signaling, SIB signaling.

In some embodiments, the third signaling may be radio resource control (radio resource control, RRC) signaling. Or the third signaling may also be signaling sent by the core network. Or the third signaling may be NAS signaling.

In some embodiments, the determining the target cell from the candidate cells according to at least one of the terminal identifier, the cell identifier, the physical cell identifier, the terminal type, the service type, the number of access resources of the cell, and the access parameter may include at least one of the following a1-a 7:

a1, determining a target cell from the candidate cells based on the terminal identification.

As an example, when mod (terminal identity, a) =mod (cell identity, a), the terminal (i.e. the first node) corresponding to the terminal identity may access the target cell corresponding to the cell identity. Wherein A is a positive integer. In some embodiments, a is predefined or signaled. Or when mod (terminal identifier, a) =mod (physical cell identifier, a), the terminal (i.e. the first node) corresponding to the terminal identifier may access the target cell corresponding to the physical cell identifier. Wherein A is a positive integer. In some embodiments, a is predefined or signaled.

As another example, when mod (terminal identification, a) =b, the terminal (i.e., the first node) to which the terminal identification corresponds may access the second type cell (i.e., the non-anchor cell). Wherein A is a positive integer, and B is an integer greater than or equal to 0.

As yet another example, when mod (terminal identification, a) =b, the terminal (i.e., the first node) to which the terminal identification corresponds selects, as the target cell, the cell whose absolute value of the difference between the cell identification or the physical cell identification and B is smallest.

As yet another example, the first node selects mod (terminal identification, X) +1 cells from the X cells as target cells. The X cells are ordered according to the size of the cell identifier or the physical cell identifier or the order of the measurement results.

As yet another example, when mod (terminal identity, cell identity/physical cell identity) =b, the terminal (i.e. the first node) to which the terminal identity corresponds can access the cell. B is an integer greater than or equal to 0.

A2, determining a target cell from the candidate cells based on the access priority.

In some embodiments, the first node selects the cell with the highest access priority as the target cell.

The access priority may be indicated by the base station through signaling/signaling, or indicated by the core network, or indicated by the NAS, or calculated by the cell identity or the physical cell identity. For example, the larger the physical cell identity, the lower the access priority. In some embodiments, the access priority is derived from predefined information.

A3, determining a target cell from the candidate cells based on the number of the access resources of the cells.

The first node selects, as the target cell, a cell with the highest number of access resources of the cell.

A4, determining a target cell from the candidate cells based on the terminal type.

In some embodiments, the first node selects the cell it has camped on or has recently camped on or selects the cell it has last camped on as the target cell.

And a5, determining a target cell from the candidate cells based on the access parameters.

In some embodiments, the access parameter may be an access weight of the cell.

As an example, each cell indicates the number of access resources by the access weight and the cell, and the first node selects the cell having the largest product of the access weight and the number of access resources of the cell as the target cell.

As another example, the first node may select a cell with the largest access weight as the target cell.

And a6, determining a target cell from the candidate cells based on the service type.

For example, when the data packet corresponding to the service type is larger or the delay requirement is high, the first node selects the first type cell as the target cell.

It can be understood that the first type cell is a cell in a normal state at this time, so that the first node can be ensured to access faster.

For example, when the data packet corresponding to the service type is large and the delay requirement is low, the first node may select the second type cell as the target cell.

It will be appreciated that at this point no user access is available in the second type of cell (and in the non-anchor cell), and that there may be sufficient resources to transmit data after access by the first node.

A7, determining a target cell from the candidate cells based on the group (group) identification.

As an example, the first cell is selected from the X cellsAnd accessing the cells as target cells. Wherein, N groups are total number of groups, and group ID is group identification. The X cells are ordered according to the size of the cell identifier or the order of the measurement results.

As another example, when mod (cell identification, a) =group identification, a cell corresponding to the cell identification is determined as the target cell. Wherein A is a positive integer.

In some embodiments, the group identity is associated with a group of cells.

As an example, when the terminal identity/group identity is an integer, the first node may access the cell to which the group identity corresponds.

As another example, when mod (terminal identity, a) =group identity, the first node may access the cell to which the group identity corresponds.

In some embodiments, a is predefined or signaled. The grouping information of the cells is determined by the core network.

In some embodiments, the method for determining a target cell provided above may also be combined to comprehensively determine the target cell.

For example, cells are divided into groups, which are distinguished by group identities. When the same group has the same access measurement threshold and multiple candidate cells exist in the group, the first node may randomly select one cell as the target cell. In the case that there is at most one candidate cell in each group, the first node selects a cell with the best measurement result as a target cell, or the first node may further determine the target cell according to at least one of a terminal identifier, a signaling indication, a cell identifier, and an access priority selection target.

For example, there may be a plurality of candidate cells, which may be indicated by signaling, e.g., core network signaling, NAS signaling, MIB, SIB, etc., or all cells that are available or accessible to the first node. The first node selects cells meeting the conditions from the candidate cells according to the measurement result, and if the number of the cells meeting the conditions is greater than 1, the target cell can be determined from the candidate cells according to at least one of terminal identification, cell identification, physical cell identification, terminal type, service type, access resource number of the cells and access parameters.

That is, the first node may use a combination of methods of determining the target cell until a target cell is determined from among the plurality of cells.

In some embodiments, the order of use of the different methods of determining the target cell may be predefined, or signaled.

It will be appreciated that the access information includes information of different dimensions of the first type cell and the second type cell, and information required for the first node to perform access. The first node determines the target cell from the candidate cells based on the access information, so that the judgment and selection of the target cell by the first node can be more accurate, the first node can be ensured to smoothly access the target cell, and the stability of the first node for accessing and the access instruction are ensured.

In some embodiments, as shown in fig. 6, the step S101 may be specifically implemented as: steps S501-S502.

As one example, the fourth signaling includes at least one of: identification of one cell, PCI of one cell. At this time, the fourth signaling indicates only one cell, and the first node may determine that the candidate cell is one cell in the fourth signaling based on the fourth signaling.

As another example, the fourth signaling includes at least one of: the method comprises the steps of identifying a candidate cell, identifying a physical cell of the candidate cell, identifying a list of the candidate cell, identifying the physical cell of the candidate cell, and indicating whether to access the cell. At this time, the candidate cell indicated by the fourth signaling may be more than one, that is, the first node may further need to determine the target cell among the candidate cells.

In some embodiments, the identity of the candidate cell identifies the cell that can be accessed. The list of candidate cell identities indicates one or more cells that can be accessed. Including cells of a first type and cells of a second type. In the list of candidate cell identifiers, each cell identifier corresponds to one index, and the fourth signaling indicates the cell identifier by indicating the index. Illustratively, the indication i in the fourth signaling, i.e. representing an identity indicating the i+1th cell in the list. Or the fourth signaling may also indicate the identity of the candidate cell via the X bit. Illustratively, the number of bits of the fourth signaling indicating the identity of the candidate cell is determined by the number of cells in the list of identities of the candidate cell. For example, if the number of cells in the candidate cell identification list is a, the fourth signaling indicates that the number of bits of the candidate cell identification isWherein each codeword corresponds to a cell identity. For another example, if the number of cells in the candidate cell identification list is a, the fourth signaling indicates that the number of bits of the candidate cell identification is a. Each bit corresponds to a cell in the list of identities of one candidate cell. For example, the corresponding cell may be prohibited from accessing with '0' and the corresponding cell may be allowed to access with '1'.

In some embodiments, the fourth signaling further includes a list of identities of candidate cells, and each index (index) in the list corresponds to a list of identities of a set of candidate cells.

In some embodiments, the fourth signaling includes a plurality of blocks (blocks) for indicating identities of a plurality of candidate cells/identity lists of candidate cells, the identity of each candidate cell/identity list of each candidate cell being indicated in one block. For example, the number of bits in the fourth signaling indicating the candidate cell is determined by the number of identities of the candidate cell/identity list of the candidate cell. One or more bits constitute a block. Each block in the fourth signaling indicates access information of an identity of one candidate cell/an identity list of the candidate cell.

Illustratively, the indication i in the fourth signaling, i.e. representing the PCI identification indicating the i+1th cell in the list. Or the fourth signaling may also indicate the PCI identification of the candidate cell via the X bit. Illustratively, the number of bits of the fourth signaling indicating the candidate cell identity is determined by the number of cells in the PCI identity list of the candidate cell. For example, if the number of cells in the PCI identification list of the candidate cell is a, the fourth signaling indicates that the number of bits of the candidate cell identification isEach codeword corresponds to a cell identity. For another example, if the number of cells in the PCI identification list of the candidate cell is a, the fourth signaling indicates that the number of bits of the candidate cell identification is a. Each bit corresponds to a cell in a list of cell identities. For example, the corresponding cell may be prohibited from accessing with '0' and the corresponding cell may be allowed to access with '1'.

In some embodiments, the fourth signaling further includes a list of PCI identities of candidate cells, and each of the lists corresponds to a list of PCI identities of a group of candidate cells.

In some embodiments, the fourth signaling includes a plurality of blocks, where the plurality of blocks is used to indicate PCI identities of a plurality of candidate cells/PCI identity lists of candidate cells, and the PCI identity of each candidate cell/PCI identity list of each candidate cell is indicated in one block. For example, the number of bits in the fourth signaling indicating the candidate cell PCI is determined by the number of candidate cell PCI identities/candidate cell PCI identity list. One or more bits constitute a block. Each block in the fourth signaling indicates access information of a candidate cell's PCI identification/candidate cell's PCI identification list.

In some embodiments, the above indication for indicating whether to access a cell may indicate whether the first node may access a cell receiving the fourth signaling or whether the first node may access a cell of the first type (i.e., an anchor cell). The indication for indicating whether to access a cell may be indicated by 1 bit, the different states of the bits representing accessibility or non-accessibility, for example. For example, 0 represents no access and 1 represents access.

In some embodiments, the above indication for indicating whether to access a cell may also indicate whether the first node may access a second type of cell (i.e., a non-anchor cell). The indication for indicating whether to access a cell may be indicated by 1 bit, the different states of the bits representing accessibility or non-accessibility, for example. For example, 0 represents no access and 1 represents access. The first node may select one of the second type cells to access if it indicates that the second type cells may be accessed.

In some embodiments, the above indication for indicating whether to access a cell may also indicate that the first node accesses a first type cell or a second type cell. The indication for indicating whether to access a cell may be indicated by 1 bit, the different states of the bits representing access to different types of cells, for example. For example, 0 represents accessing a second type cell and 1 represents accessing a first type cell.

The first node firstly judges whether the first cell can be accessed, and if so, the first cell is a target cell. If not, then continue to determine if the second cell is accessible, and so on. Wherein the access priority of the cells is related to the order in the list.

In some embodiments, the above determination of the target cell from the candidate cells may be further implemented as: determining a target cell from the candidate cells according to the access information; and/or determining the target cell from the candidate cells according to at least one of the first node identification, the cell identification, the physical cell identification, the first node type, the service type, the number of access resources of the cells and the access parameters.

Or the target cell may be a plurality of candidate cells for subsequent determination by the first node of a cell to be accessed from among the plurality of candidate cells.

In some embodiments, the various methods of determining target/candidate cells described in embodiments of the disclosure may be used in combination. For example, the measurement result (e.g., RSRP) is used to determine a candidate cell, then a second candidate cell is determined in the candidate cell according to the group identification, and then the target cell is determined in the second candidate cell according to the signaling indication. For another example, a candidate cell that can be accessed is determined according to the signaling indication, and then a target cell is determined in the candidate cell according to the measurement result. For another example, the candidate cell that can be accessed is determined according to the terminal and the signaling, and then the target cell is determined according to the measurement result.

In some embodiments, determining the target cell as the first step of determining the target cell is based on signaling. In some embodiments, the step of determining the target cell as a final target cell is based on the measurement results.

In some embodiments, the priority of the target/candidate cell determined from the signaling indication is greater than the priority of the target cell determined from the access information and based on at least one of the first node identity, the cell identity, the physical cell identity, the first node type, the traffic type, the number of access resources of the cell, the access parameter. That is, when the signaling indicates that the target/candidate cell is accessible, the target/candidate cell which is determined by the access information and based on at least one of the first node identification, the cell identification, the physical cell identification, the first node type, the traffic type, the number of access resources of the cell, the access parameter and is not within the signaling indication range is not considered.

In some embodiments, the target/candidate cell determined from the measurement results has the highest priority, i.e. the target cell determined using the various methods must be the target/candidate cell determined from the measurement results.

In some embodiments, the target/candidate cells are determined in a plurality of ways without successes, and the final determined target cell is the intersection of the target/candidate cells determined in the plurality of ways. Or the final determined target cell is the intersection of the target/candidate cells determined in a number of ways used.

When the fourth signaling is signaling accessed on the first type cell, the fourth signaling is indicated by at least one of: SSB, MIB, DCI, paging, PDSCH, PEI, LP-WUS, SI-RNTI scrambled DCI, SIB1.

Illustratively, the first node receives SIB1 for the first type cell on the first type cell, and includes fourth signaling on SIB1 for only the first type cell.

In some embodiments, the LP WUS signaling may be received on a first type of cell or on a second type of cell.

In some embodiments, when the LP WUS signaling indicates whether a certain cell (i.e., the cell receiving the LP WUS signaling) can be accessed, the LP WUS signaling may be received on the first type of cell or on the second type of cell.

In some embodiments, when the LP WUS signaling indicates cell ID, PCI list (list), etc., the LP WUS signaling is received on the first type of cell.

It is understood that the second type cell is a non-anchor cell, which cannot send SIB information, i.e., the first node cannot receive SIB, PAGING DCI, PEI, etc. information on the second type cell.

It can be understood that, besides determining the target cell based on the access information, the first node can accurately determine the target cell through the received signaling, so that unnecessary retries and access processes of the first node are avoided, network load is reduced, and resource utilization efficiency is improved.
