[0049] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be specifically described below through embodiments and in combination with the accompanying drawings. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0051] In addition, the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0052] An embodiment of the present application provides a paging monitoring method, which is applied to a terminal. The terminal can specifically be an electronic device such as a mobile phone or a tablet computer, and the embodiments of the present application do not make any limitations.

[0053] Figure 1 A flowchart of a paging monitoring method provided by an embodiment of the present application. As Figure 1 shown, in the embodiment of the present application, the paging monitoring method mainly includes the following steps:

[0054] S101. Receive system messages on a first carrier; wherein, the system messages include: a carrier combination, and for each carrier in the carrier combination, the subcarrier spacing of the paging control resource set CORESET, the frequency offset of the synchronization signal block SSB, and the paging search space configuration.

[0055] In the embodiment of the present application, the terminal can receive system messages on the first carrier.

[0056] It should be noted that, in the embodiment of the present application, the first carrier can be a certain carrier selected by the terminal. For example, the first carrier can be an anchor carrier. In the system messages, the carrier combination is composed of multiple carriers. The first carrier and each carrier in the carrier combination are not limited in the embodiments of the present application. In addition, each carrier can also be described as a sub-band.

[0057] It is understandable that in the embodiments of the present application, the system message received by the terminal on the first carrier includes a carrier combination, the subcarrier spacing of the paging control resource set (CORESET) of each carrier in the carrier combination, the frequency offset of the Synchronization Signal Block (SSB), and the paging search space configuration. Through this information, the terminal can determine the time-domain position and frequency-domain position for listening to paging on any carrier in the carrier combination. In this way, not only can the signaling overhead in the paging process be effectively reduced, but also the delay caused by changing the carrier to listen to paging and then re-obtaining the relevant configuration from the corresponding carrier can be avoided, achieving a compromise between paging capacity and blind detection complexity.

[0058] In the embodiments of the present application, the subcarrier spacing of the CORESET of each carrier in the carrier combination may specifically be the subcarrier spacing of CORESET #0 of the 5G New Radio (NR) of each carrier.

[0059] S102. Determine a second carrier for listening to paging from the carrier combination.

[0060] In the embodiments of the present application, after obtaining the system message, the terminal further determines a second carrier for listening to paging from the carrier combination included in the system message.

[0061] In the embodiments of the present application, the terminal determines a second carrier for listening to paging from the carrier combination, including: determining the second carrier based on the paging weights of each carrier in the carrier combination; wherein the system message further includes the paging weights of each carrier in the carrier combination; or, measuring each carrier in the carrier combination to obtain the measurement results of each carrier in the carrier combination; and determining the second carrier based on the measurement results of each carrier in the carrier combination.

[0062] It should be noted that in the embodiments of the present application, the system message may include the paging weights of each carrier. Based on this, the terminal can select the second carrier based on the paging weights of each carrier. The specific rules or methods for selecting based on the paging weights can be determined in combination with actual communication requirements and application scenarios, and are not limited in the embodiments of the present application.

[0063] It should be noted that in the embodiments of the present application, the terminal can also measure each carrier in the carrier combination and select the second carrier based on the measurement results. For example, select the carrier with the best measurement result as the second carrier to ensure better paging listening quality, which is not limited in the embodiments of the present application.

[0064] It should be noted that in the embodiments of the present application, the above two methods for determining the second carrier are only exemplary and optional methods. Of course, other methods can also be used to determine the second carrier according to actual requirements and application scenarios, and the embodiments of the present application do not make any limitations.

[0065] S103. Determine the frequency-domain position for listening for paging on the second carrier based on the SSB frequency offset of the second carrier.

[0066] In the embodiments of the present application, after the terminal determines the second carrier for listening for paging, it can determine the frequency-domain position for listening for paging on the second carrier based on the SSB frequency offset of the second carrier.

[0067] In the embodiments of the present application, the system message further includes: the paging CORESET configuration index of each carrier in the carrier combination; the terminal determines the frequency-domain position for listening for paging on the second carrier based on the SSB frequency offset of the second carrier, including: receiving a synchronization signal on the second carrier and determining the subcarrier spacing of the synchronization signal; based on the subcarrier spacing of the synchronization signal, the subcarrier spacing of the paging CORESET of the second carrier, and the minimum channel bandwidth of the frequency band to which the second carrier belongs, determining the mapping relationship between the paging CORESET configuration index of the second carrier and the paging CORESET configuration; obtaining the paging COREST configuration of the second carrier based on the determined mapping relationship; obtaining the frequency-domain offset between the paging CORESET of the second carrier and the SSB from the paging CORESET configuration of the second carrier; determining the Resource Block (RB) boundary based on the SSB frequency offset of the second carrier, and based on the RB boundary and the frequency-domain offset, determining the frequency-domain position for listening for paging on the second carrier.

[0068] Exemplarily, taking the CORESET#0 configuration of 5G NR as an example: The system message received by the terminal on the first carrier includes a carrier combination of {carrier 1, carrier 2}, and the index value corresponding to carrier 2 is 2. Assume that the second carrier is carrier 2, the subcarrier spacing of the synchronization signal and CORESET#0 of carrier 2 are both 30 kHz, and the minimum channel bandwidth of the frequency band to which it belongs is 10 MHz. Then, according to the protocol regulations, referring to Table 1 below, the terminal can determine the CORESET#0 configuration corresponding to index 2, obtain that the bandwidth of CORESET#0 of carrier 2 is 24 RBs, the number of symbols is 2, and the frequency-domain offset from the SSB is 2 RBs. The terminal determines the RB boundary according to the SSB frequency offset of carrier 2, and then determines the specific frequency-domain position of CORESET#0 based on the RB boundary and the frequency-domain offset between CORESET#0 and the SSB, and obtains the frequency-domain position for listening for paging on carrier 2.

[0071]

[0072] In an embodiment of the present application, the system message further includes: the paging CORESET bandwidth of each carrier in the carrier combination; the terminal can also perform the following steps to determine the frequency-domain position for listening to paging on the second carrier based on the SSB frequency offset of the second carrier: receive a synchronization signal on the second carrier; determine the starting position of the paging CORESET of the second carrier based on the SSB frequency offset of the second carrier and the frequency-domain offset bandwidth between the paging CORESET and the synchronization signal; and determine the frequency-domain position for listening to paging on the second carrier based on the paging CORESET bandwidth and the starting position of the paging CORESET of the second carrier.

[0073] It should be noted that, in an embodiment of the present application, the system message may include the paging CORESET bandwidth of each carrier in the carrier combination. The configuration method of the paging CORESET bandwidth may use a predefined minimum CORESET bandwidth as the reference bandwidth to indicate the relationship between the paging CORESET bandwidth of each carrier and the reference bandwidth, such as multiples, differences, etc. Of course, it may also independently indicate the paging CORESET bandwidth of each carrier, and the embodiments of the present application do not make any limitations.

[0074] S104. Determine the time-domain position for listening to paging on the second carrier based on the paging CORESET subcarrier spacing and the paging search space configuration of the second carrier.

[0075] In an embodiment of the present application, after the terminal determines the second carrier for listening to paging, it can determine the time-domain position for listening to paging on the second carrier based on the paging CORESET subcarrier spacing and the paging search space configuration of the second carrier.

[0076] In an embodiment of the present application, the terminal determines the time-domain position for listening to paging on the second carrier based on the subcarrier spacing and the paging search space configuration of the second carrier, including: determining a paging frame (PF) based on the terminal identifier and determining a target paging occasion (PO) associated with the PF and corresponding to the terminal; obtaining the number of symbols occupied by the paging monitoring occasion (PMO) of the second carrier; determining the target PMO associated with the target PO based on the paging search space configuration of the second carrier, the number of symbols occupied by the PMO, and the paging CORESET subcarrier spacing; and determining the time-domain position for listening to paging on the second carrier based on the target PMO.

[0077] In an embodiment of the present application, in the system message, the number of symbols occupied by the paging monitoring opportunity (PMO) of the second carrier obtained by the terminal includes: obtaining the number of symbols occupied by the PMO of the second carrier from the paging CORESET configuration of the second carrier; or, the system message further includes the paging CORESET duration, and determining the number of symbols occupied by the PMO of the second carrier based on the paging CORESET duration and the paging CORESET subcarrier spacing of the second carrier.

[0078] It should be noted that, in an embodiment of the present application, the system message may further include the paging CORESET duration of each carrier in the carrier combination. In order to implement paging across carriers simultaneously, the paging CORESETs of each carrier should occupy the same time domain position. Therefore, the configuration method of the paging CORESET duration may be to indicate a duration.

[0079] It can be understood that the PMO is related to the specific symbol position for monitoring paging, and the symbol length is related to the subcarrier spacing. When different terminals within the same PF select different carriers to monitor paging, or when the terminal selects different carriers to monitor paging in different paging cycles due to reasons such as channel condition changes and load changes, if the subcarrier spacings of each carrier are different, and the position of the PMO is determined according to the same search space configuration, the terminal will experience situations such as monitoring without paging and missing paging when there is paging, resulting in additional energy consumption and missed paging, as Figure 2 shown. Based on this, as described in step S101, in the present application, the paging search space configuration of each carrier is carried in the system message to accurately determine the time domain position for monitoring paging.

[0080] In an embodiment of the present application, in the system message, the paging search space configurations of each carrier in the carrier combination may be jointly indicated, including the paging search space configured with the reference subcarrier spacing, the PMO of each PO, and the number of PMOs, where the reference subcarrier spacing is the paging CORESET subcarrier spacing predefined or configured by higher layer signaling, for example, 15 kHz, or the minimum paging CORESET subcarrier spacing included in the system message. The specific reference subcarrier spacing may be selected according to actual requirements and application scenarios, and is not limited in the embodiments of the present application.

[0081] In an embodiment of the present application, in the system message, the paging search space configurations of each carrier in the carrier combination may also be independently indicated, and the paging search space of each carrier respectively includes the corresponding paging search space, the starting PMO of each PO, and the number of PMOs.

[0082] It can be understood that in the embodiments of the present application, as described above, the paging search space configuration of each carrier in the carrier combination can be jointly indicated or independently indicated in the system message. Among them, the joint indication method can reduce the amount of data carried in the system message. The specific indication method of the paging search control configuration can be set according to actual requirements and application scenarios, and the embodiments of the present application do not make limitations.
