[0027] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: a number of terminals 11 and a number of base stations 12.

[0028] Terminal 11 can be a device that provides voice and / or data connectivity to a user. Terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN). Terminal 11 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, terminal 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, terminal 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, terminal 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0029] Base station 12 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0030] In this embodiment, base station 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, base station 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When base station 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of base station 12.

[0031] Base station 12 and terminal 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0032] In some embodiments, terminals 11 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0033] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0034] Several base stations 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0035] The execution entities involved in the embodiments disclosed herein include, but are not limited to, UEs such as mobile terminals that support cellular mobile communication, and base stations, etc.

[0036] One application scenario of this disclosure is that the NR system can introduce multi-carrier serving cells, such as... Figure 2 As shown, a multi-carrier serving cell consists of multiple carriers, such as CC1, CC2, and CC3, where CC1 is the primary carrier and CC2 and CC3 are secondary carriers. The UE can only obtain system messages and receive paging through the primary carrier CC1, and can perform Radio Resource Management (RRM) measurements and initiate Physical Random Access Channel (PRACH) access on all carriers. When the serving cell is FR2, according to the existing scheme, the UE needs to camp on the FR2 cell in the RRC idle state, which consumes a lot of power. If a multi-carrier serving cell is configured (one FR1 carrier and two FR2 carriers), the UE can camp on the FR1 carrier in the idle state. If there is service, the UE initiates PRACH and directly returns to the FR2 carrier for data transmission and reception. This achieves the effect of saving base station power. Therefore, it is necessary to study the cell reselection configuration method for terminal UEs in multi-carrier serving cell scenarios.

[0037] In related technologies, a serving cell consists of only one carrier. The UE can determine whether to perform cell reselection by comparing the radio signal measurement value of that carrier with the reselection threshold of that carrier. Multi-carrier cells, however, involve multiple carriers, and how the UE determines whether cell reselection is necessary in a multi-carrier cell is a problem that urgently needs to be solved.

[0038] like Figure 3 As shown, this exemplary embodiment provides a cell reselection configuration method, which can be applied to access network equipment in multi-carrier cells, including:

[0039] Step 301: Send the reselection configuration information of the multi-carrier cell, wherein the reselection configuration information indicates at least one reselection threshold value for the UE to perform cell reselection.

[0040] Here, UE can be a mobile phone UE that uses cellular mobile communication technology for wireless communication. A multi-carrier cell can be the UE's current serving cell. A multi-carrier cell can include multiple carriers, including a primary carrier and secondary carriers. The UE can only obtain system messages and receive paging through the primary carrier, and the UE can perform RRM measurements and initiate PRACH access on all carriers. Access network equipment can be a base station, etc., that provides an access network interface to the UE in a cellular mobile communication system.

[0041] The access network device can send reselection configuration information to the UE, indicating at least one reselection threshold. The reselection threshold can be a reselection threshold for one carrier, a reselection threshold for multiple carriers, or a reselection threshold for each carrier individually. The UE can be a UE in RRC idle state or RRC inactive state, or a UE in connected state.

[0042] A reselection threshold can be a threshold value used to indicate the quality of a carrier signal. When the measured value of the carrier's radio signal is lower than the reselection threshold, it indicates that the carrier's signal quality does not meet the requirements of current communication. The reselection threshold can include signal strength thresholds, signal-to-noise ratio thresholds, etc.; the corresponding radio signal measurements can include signal strength, signal-to-noise ratio, etc.

[0043] The UE can determine cell reselection based on the carrier targeted by the received reselection threshold. For example, when only the reselection threshold of a carrier is received, if the radio signal measurement value of that carrier is less than the reselection threshold, cell reselection is performed; otherwise, cell reselection is not performed, and the UE continues to camp on the current serving cell.

[0044] In one embodiment, the access network device may send reselection configuration information to the UE by including it in a system message. For example, the access network device may send the reselection configuration information to the UE by including it in a System Information Block (SIB).

[0045] The UE can determine which carriers require comparison of radio signal measurements with a reselection threshold and perform radio signal measurements.

[0046] In one embodiment, the reselection threshold includes: a reference signal receiving power (RSRP) threshold and / or a reference signal receiving quality (RSRQ) threshold.

[0047] The radio signal measurement values ​​obtained by the UE during radio signal measurement may include: RSRP and / or RSRQ. RSRP can be compared with an RSRP threshold, and / or RSRQ can be compared with an RSRQ threshold.

[0048] Thus, for multi-carrier cells, the access network device can send reselection configuration information indicating at least one reselection threshold value, and the UE can determine cell reselection based on the determined at least one reselection threshold value. The access network device can flexibly indicate the determination conditions for cell reselection to the UE by sending different reselection threshold values, thereby improving the flexibility of cell reselection and realizing cell reselection in multi-carrier cells to meet the needs of cellular mobile communication.

[0049] In one embodiment, the reselection configuration information indicates at least one of the following:

[0050] Multiple reselection threshold values, wherein different reselection threshold values ​​are reselection threshold values ​​for different carriers within the multi-carrier cell;

[0051] A reselection threshold value, wherein the reselection threshold value is a reselection threshold value that is common to different carriers in the multi-carrier cell.

[0052] A multi-carrier cell may include one primary carrier and at least one secondary carrier. Here, the multiple reselection thresholds indicated by the reselection configuration information may include: reselection thresholds corresponding to the radio signal measurement values ​​of the primary carrier and the radio signal measurement values ​​of at least one secondary carrier, etc. For example, the multiple reselection thresholds indicated by the reselection configuration information may include: reselection thresholds corresponding to all carriers within the multi-carrier cell. The multiple reselection thresholds indicated by the reselection configuration information may also include: reselection thresholds corresponding to the radio signal measurement values ​​of multiple predetermined carriers, etc., for example, reselection thresholds corresponding to all secondary carriers.

[0053] For example, the reselection configuration information indicating multiple reselection thresholds may include reselection thresholds corresponding to radio signal measurements of a primary carrier and radio signal measurements of at least one secondary carrier. For instance, the reselection configuration information indicates multiple reselection thresholds R0, R1, ... Ri, where R0 corresponds to the reselection threshold of the primary carrier f0 (anchor frequency carrier), R1 corresponds to the threshold of the secondary carrier f1 (non-anchor frequency carrier), and Ri corresponds to the reselection threshold of the secondary carrier fi; here, the reselection thresholds may be RSRP thresholds or RSRQ thresholds, etc.

[0054] The UE can select one or more reselection thresholds from the reselection thresholds common to different carriers in a multi-carrier cell and compare them with the radio signal measurement values ​​of the corresponding carriers to determine whether to perform cell reselection.

[0055] In one embodiment, the UE performs cell reselection in response to the reselection configuration information indicating a plurality of reselection thresholds, and the radio signal measurement value of each carrier being less than the reselection threshold of each carrier.

[0056] For example, the multiple reselection thresholds indicated by the reselection configuration information may include reselection thresholds corresponding to each carrier in a multi-carrier cell. The UE can measure the radio signal of each carrier in the multi-carrier cell and compare the radio signal measurement value of each carrier with the corresponding reselection threshold value. If the radio signal measurement value of each carrier is less than the corresponding reselection threshold value, it indicates that none of the carriers can meet the communication requirements, and cell reselection is required.

[0057] For example, if the radio signal measurement (RSRP or RSRQ) of the UE on all carriers is lower than the corresponding configuration threshold R0, R1, ... Ri, the UE can perform cell reselection.

[0058] In this way, the UE compares the radio signal measurement values ​​of different carriers with the corresponding reselection threshold to determine whether to perform cell reselection, thereby realizing the evaluation of multiple carriers in a multi-carrier cell and improving the reliability of cell reselection in a multi-carrier cell.

[0059] In one embodiment, in response to the reselection configuration information indicating multiple reselection thresholds, and at least one of the carrier's radio signal measurement values ​​being greater than or equal to the corresponding reselection threshold, the UE remains camped in the current serving cell and does not perform the cell reselection.

[0060] If the radio signal measurement value of at least one carrier is greater than or equal to the corresponding reselection threshold, it means that there are still carriers in the current serving cell that can meet the communication requirements, and the UE can camp in the current serving area.

[0061] In one embodiment, the reselection threshold values ​​for different carriers within the multi-carrier cell include at least the reselection threshold value for the primary carrier within the multi-carrier cell.

[0062] For example, the UE can measure the radio signal of the primary carrier within the carrier cell and compare the measured value of the primary carrier's radio signal with the primary carrier's reselection threshold. If the measured value of the primary carrier's radio signal is less than the corresponding reselection threshold, it can be determined that the primary carrier cannot meet the communication requirements such as obtaining system messages and receiving paging, and cell reselection is required.

[0063] If the radio signal measurements of the primary carrier are all greater than or equal to the corresponding reselection threshold, it can be determined that the primary carrier can meet the communication requirements such as obtaining system messages and receiving paging, and can camp on the current serving cell.

[0064] Since the primary carrier carries system messages, paging messages, etc., it plays a decisive role in communication. If the primary carrier does not meet communication requirements, the UE and base station cannot achieve a complete communication process. Determining whether to perform cell reselection by using the primary carrier improves the efficiency of cell reselection assessment because the UE only compares the radio signal measurement value of one carrier with the corresponding reselection threshold.

[0065] The reselection configuration information indicates a reselection threshold value that may be common to all carriers within the carrier cell. The UE may compare the radio signal measurement values ​​of each carrier with the reselection threshold value individually; or it may compare the statistical values ​​of the radio signal measurement values ​​of each carrier, such as a weighted average, with the reselection threshold value.

[0066] In one embodiment, the reselection threshold value corresponding to different carriers in the multi-carrier cell includes: the reselection threshold value corresponding to the average value of the radio signal measurements of the different carriers.

[0067] For example, the UE can measure the radio signal of each carrier in the carrier cell and determine the average value of the radio signal measurement of each carrier. Then, it can compare the average value with the reselection threshold value corresponding to the average value. If the average value is less than the corresponding reselection threshold value, it can be determined that the signal quality of the current serving cell is poor and cell reselection can be performed.

[0068] If the average value is greater than or equal to the corresponding reselection threshold, it can be determined that the signal quality of the current serving cell can meet the communication requirements, and cell reselection can be avoided, allowing the cell to remain in the current serving cell.

[0069] By comparing the average value of the radio signal measurements of each carrier with the corresponding reselection threshold, the decision on whether to perform cell reselection is made, reducing the number of reselection thresholds to be compared and improving the efficiency of cell reselection assessment.

[0070] like Figure 4 As shown, this exemplary embodiment provides an information transmission method, which can be applied in a UE, including:

[0071] Step 401: Receive reselection configuration information for a multi-carrier cell, wherein the reselection configuration information indicates at least one reselection threshold value for the UE to perform cell reselection.

[0072] Here, UE can be a mobile phone UE that uses cellular mobile communication technology for wireless communication. A multi-carrier cell can be the UE's current serving cell. A multi-carrier cell can include multiple carriers, including a primary carrier and secondary carriers. The UE can only obtain system messages and receive paging through the primary carrier, and the UE can perform RRM measurements and initiate PRACH access on all carriers. Access network equipment can be a base station, etc., that provides an access network interface to the UE in a cellular mobile communication system.

[0073] The access network device can send reselection configuration information to the UE, indicating at least one reselection threshold. The reselection threshold can be a reselection threshold for one carrier, a reselection threshold for multiple carriers, or a reselection threshold for each carrier individually. The UE can be a UE in RRC idle state or RRC inactive state, or a UE in connected state.

[0074] A reselection threshold can be a threshold value used to indicate the quality of a carrier signal. When the measured value of the carrier's radio signal is lower than the reselection threshold, it indicates that the carrier's signal quality does not meet the requirements of current communication. The reselection threshold can include signal strength thresholds, signal-to-noise ratio thresholds, etc.; the corresponding radio signal measurements can include signal strength, signal-to-noise ratio, etc.

[0075] The UE can determine cell reselection based on the carrier targeted by the received reselection threshold. For example, when only the reselection threshold of a carrier is received, if the radio signal measurement value of that carrier is less than the reselection threshold, cell reselection is performed; otherwise, cell reselection is not performed, and the UE continues to camp on the current serving cell.

[0076] In one embodiment, the access network device may send reselection configuration information to the UE by including it in a system message. For example, the access network device may send the reselection configuration information to the UE by including it in a System Information Block (SIB).

[0077] The UE can determine which carriers require comparison of radio signal measurements with a reselection threshold and perform radio signal measurements.

[0078] In one embodiment, the reselection threshold includes: a reference signal received power (RSRP) threshold and / or a reference signal received quality (RSRQ) threshold.

[0079] The radio signal measurement values ​​obtained by the UE during radio signal measurement may include: RSRP and / or RSRQ. RSRP can be compared with an RSRP threshold, and / or RSRQ can be compared with an RSRQ threshold.

[0080] Thus, for multi-carrier cells, the access network device can send reselection configuration information indicating at least one reselection threshold value, and the UE can determine cell reselection based on the determined at least one reselection threshold value. The access network device can flexibly indicate the determination conditions for cell reselection to the UE by sending different reselection threshold values, thereby improving the flexibility of cell reselection and realizing cell reselection in multi-carrier cells to meet the needs of cellular mobile communication.

[0081] In one embodiment, the reselection configuration information indicates at least one of the following:

[0082] Multiple reselection threshold values, wherein different reselection threshold values ​​are reselection threshold values ​​for different carriers within the multi-carrier cell;

[0083] A reselection threshold value, wherein the reselection threshold value is a reselection threshold value that is common to different carriers in the multi-carrier cell.

[0084] A multi-carrier cell may include one primary carrier and at least one secondary carrier. Here, the multiple reselection thresholds indicated by the reselection configuration information may include: reselection thresholds corresponding to the radio signal measurement values ​​of the primary carrier and the radio signal measurement values ​​of at least one secondary carrier, etc. For example, the multiple reselection thresholds indicated by the reselection configuration information may include: reselection thresholds corresponding to all carriers within the multi-carrier cell. The multiple reselection thresholds indicated by the reselection configuration information may also include: reselection thresholds corresponding to the radio signal measurement values ​​of multiple predetermined carriers, etc., for example, reselection thresholds corresponding to all secondary carriers.

[0085] For example, the reselection configuration information indicating multiple reselection thresholds may include reselection thresholds corresponding to radio signal measurements of a primary carrier and radio signal measurements of at least one secondary carrier. For instance, the reselection configuration information indicates multiple reselection thresholds R0, R1, ... Ri, where R0 corresponds to the reselection threshold of the primary carrier f0 (anchor frequency carrier), R1 corresponds to the threshold of the secondary carrier f1 (non-anchor frequency carrier), and Ri corresponds to the reselection threshold of the secondary carrier fi; here, the reselection thresholds may be RSRP thresholds or RSRQ thresholds, etc.

[0086] In one embodiment, the method further includes: performing cell reselection based on a comparison between the radio signal measurement value of the multi-carrier cell and the reselection threshold value.

[0087] The UE can select one or more reselection thresholds from the reselection thresholds common to different carriers in a multi-carrier cell and compare them with the radio signal measurement values ​​of the corresponding carriers to determine whether to perform cell reselection.

[0088] In one embodiment, the cell reselection based on the comparison result of the radio signal measurement value of the multi-carrier cell and the reselection threshold value includes:

[0089] In response to the reselection configuration information indicating multiple reselection thresholds, and the radio signal measurement value of each carrier being less than the reselection threshold of each carrier, the cell reselection is performed.

[0090] For example, the multiple reselection thresholds indicated by the reselection configuration information may include reselection thresholds corresponding to each carrier in a multi-carrier cell. The UE can measure the radio signal of each carrier in the multi-carrier cell and compare the radio signal measurement value of each carrier with the corresponding reselection threshold value. If the radio signal measurement value of each carrier is less than the corresponding reselection threshold value, it indicates that none of the carriers can meet the communication requirements, and cell reselection is required.

[0091] For example, if the radio signal measurement (RSRP or RSRQ) of the UE on all carriers is lower than the corresponding configuration threshold R0, R1, ... Ri, the UE can perform cell reselection.

[0092] In this way, the UE compares the radio signal measurement values ​​of different carriers with the corresponding reselection threshold to determine whether to perform cell reselection, thereby realizing the evaluation of multiple carriers in a multi-carrier cell and improving the reliability of cell reselection in a multi-carrier cell.

[0093] In one embodiment, in response to the reselection configuration information indicating multiple reselection thresholds, and at least one of the carrier's radio signal measurement values ​​being greater than or equal to the corresponding reselection threshold, the UE remains camped in the current serving cell and does not perform the cell reselection.

[0094] If the radio signal measurement value of at least one carrier is greater than or equal to the corresponding reselection threshold, it means that there are still carriers in the current serving cell that can meet the communication requirements, and the UE can camp in the current serving area.

[0095] In one embodiment, the reselection threshold values ​​for different carriers within the multi-carrier cell include at least the reselection threshold value for the primary carrier within the multi-carrier cell.

[0096] In one embodiment, the cell reselection based on the comparison result of the radio signal measurement value of the multi-carrier cell and the reselection threshold value includes:

[0097] The cell reselection is performed in response to a plurality of reselection thresholds indicated by the reselection configuration information, including a reselection threshold for the primary carrier, and the radio signal measurement value of the primary carrier is less than the reselection threshold for the primary carrier.

[0098] For example, the UE can measure the radio signal of the primary carrier within the carrier cell and compare the measured value of the primary carrier's radio signal with the primary carrier's reselection threshold. If the measured value of the primary carrier's radio signal is less than the corresponding reselection threshold, it can be determined that the primary carrier cannot meet the communication requirements such as obtaining system messages and receiving paging, and cell reselection is required.

[0099] If the radio signal measurements of the primary carrier are all greater than or equal to the corresponding reselection threshold, it can be determined that the primary carrier can meet the communication requirements such as obtaining system messages and receiving paging, and can camp on the current serving cell.

[0100] Since the primary carrier carries system messages, paging messages, etc., it plays a decisive role in communication. If the primary carrier does not meet communication requirements, the UE and base station cannot achieve a complete communication process. Determining whether to perform cell reselection by using the primary carrier improves the efficiency of cell reselection assessment because the UE only compares the radio signal measurement value of one carrier with the corresponding reselection threshold.

[0101] The reselection configuration information indicates a reselection threshold value that may include a reselection threshold value common to all carriers within the carrier cell. The UE may compare the radio signal measurement values ​​of each carrier with the reselection threshold value individually; or it may compare the statistical values ​​of the radio signal measurement values ​​of each carrier, such as a weighted average, with the reselection threshold value, and determine whether to perform cell reselection based on the comparison result.

[0102] In one embodiment, the reselection threshold value corresponding to different carriers in the multi-carrier cell includes: the reselection threshold value corresponding to the average value of the radio signal measurements of the different carriers.

[0103] In one embodiment, the cell reselection based on the comparison result of the radio signal measurement value of the multi-carrier cell and the reselection threshold value includes:

[0104] In response to the reselection configuration information indicating a reselection threshold value corresponding to the average value of the radio signal measurements of different carriers, and the average value of the radio signal measurements of different carriers being less than the reselection threshold value, the cell reselection is performed.

[0105] For example, the UE can measure the radio signal of each carrier in the carrier cell and determine the average value of the radio signal measurement of each carrier. Then, it can compare the average value with the reselection threshold value corresponding to the average value. If the average value is less than the corresponding reselection threshold value, it can be determined that the signal quality of the current serving cell is poor and cell reselection can be performed.

[0106] If the average value is greater than or equal to the corresponding reselection threshold, it can be determined that the signal quality of the current serving cell can meet the communication requirements, and cell reselection can be avoided, allowing the cell to remain in the current serving cell.

[0107] By comparing the average value of the radio signal measurements of each carrier with the corresponding reselection threshold, the decision on whether to perform cell reselection is made, reducing the number of reselection thresholds to be compared and improving the efficiency of cell reselection assessment.

[0108] The following provides a specific example in conjunction with any of the above embodiments:

[0109] 1. The serving cell configures the cell reselection threshold value through SIB system messages. The cell reselection threshold value can be configured in the following ways:

[0110] Configuration Method 1: Configure multiple cell reselection thresholds R0, R1, ...
