[0090] For the convenience of those skilled in the art to understand, the embodiments of the present disclosure enumerate a plurality of embodiments to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the plurality of embodiments provided by the embodiments of the present disclosure can be executed alone, or can be executed together with the method of other embodiments of the present disclosure, or can be executed alone or together with some methods in other related technologies; the embodiments of the present disclosure do not make any limitation in this regard.

[0091] In order to better understand the technical solutions described in any one of the embodiments of the present disclosure, first, the application scenarios of wireless communication in the related art are described:

[0092] In one embodiment, when the terminal is in a radio resource control (RRC) non-connected state, the main behavior of the terminal is to periodically listen to a paging message, and after receiving the paging message, the terminal enters an RRC connected state to perform normal communication with the network. Here, the paging message is carried in a physical downlink shared channel (PDSCH), and needs to be scheduled by a paging down control information (DCI) scrambled by a radio network temporary identifier. For a terminal, the corresponding paging occasion (PO) is periodically present. The radio frame in which the PO is located is called a paging frame (PF).

[0093] In one embodiment, the terminal needs to wake up for synchronization in each paging cycle, and blindly detect whether there is a paging DCI belonging to the terminal in the corresponding PO. In order to save the terminal energy consumption in the idle state, the base station can send a paging early indication (PEI) to the terminal. If the terminal receives the PEI corresponding to the terminal, the terminal needs to wake up before the next PO to listen to the paging message. If the PEI indicates that the terminal does not wake up, or the terminal does not receive the corresponding PEI, the terminal does not need to wake up in the next paging cycle, that is, the terminal does not need to listen to the next PO. The PEI is carried in the form of DCI. Here, the DCI can be DCI format 2-7.

[0094] In one embodiment, the PEI DCI can be provided with a TRS availability indication field for indicating whether there is information of TRS pilots. Here, the TRS can be used for terminals in RRC idle state and RRC inactive state to perform time-frequency domain tracking and synchronization. In one embodiment, the TRS availability indication field can be transmitted in the paging DCI in addition to being transmitted in the PEI. The TRS availability indication field is a bitmap containing N bits, each bit corresponding to one TRS resource set group. If the TRS availability indication field indicates that a certain TRS resource set group is available, the starting time of the indication taking effect is the starting time of the first frame of the current default paging cycle in which the terminal receives the TRS availability indication.

[0095] As shown in FIG. 21, the present embodiment provides a method for monitoring TRS availability indication information, which is performed by a terminal and includes the following steps. Figure 2

[0096] Step 21, determining that the terminal is configured to monitor the paging early indication downlink control information (PEI DCI);

[0097] Step 22, monitoring the tracking reference signal (TRS) availability indication information in a predetermined manner, wherein the predetermined manner includes at least one of the following:

[0098] a first manner of monitoring the TRS availability indication information in the PEI DCI;

[0099] a second manner of monitoring the TRS availability indication information in the paging DCI.

[0100] Here, the terminal involved in the present disclosure can be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU), a smart home terminal, an industrial sensor device, a medical device, and / or the like. Here, the terminal can be a terminal in RRC non-connected state. The RRC non-connected state includes RRC idle state and RRC inactive state.

[0101] ​The base station involved in the present disclosure can be an access device of a terminal access network. Here, the base station can be various types of base stations, such as a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations.

[0102] In one embodiment, it is determined that the terminal is configured to monitor the PEI DCI; TRS availability indication information is monitored in the PEI DCI; TRS is received based on the monitored TRS availability indication information; time-frequency domain synchronization and tracking, etc. are performed based on the TRS. It should be noted that the TRS availability indication information can include time-frequency domain resource information associated with the transmission of the TRS.

[0103] In one embodiment, it is determined that the terminal is configured to monitor the PEI DCI; TRS availability indication information is monitored in the paging DCI; TRS is received based on the monitored TRS availability indication information; time-frequency domain synchronization and tracking, etc. are performed based on the TRS.

[0104] In one embodiment, it is determined that the terminal is configured to monitor the PEI DCI; TRS availability indication information is monitored in the PEI DCI and the paging DCI; TRS is received based on the monitored TRS availability indication information; time-frequency domain synchronization and tracking, etc. are performed based on the TRS.

[0105] In one embodiment, when the terminal is configured to monitor the TRS availability indication information by the first manner, the TRS availability indication information is monitored by the first manner. It should be noted that when the terminal is configured to monitor the TRS availability indication information by the first manner, the network will transmit the TRS availability indication information in the PEI DCI.

[0106] In one embodiment, when the terminal is configured to monitor the TRS availability indication information by the second manner, the TRS availability indication information is monitored by the second manner. It should be noted that when the terminal is configured to monitor the TRS availability indication information by the second manner, the network will transmit the TRS availability indication information in the paging DCI.

[0107] In one embodiment, when the terminal is configured to monitor the TRS availability indication information by the first manner and the second manner, the TRS availability indication information is monitored by the first manner and the second manner. Here, monitoring by the first manner and the second manner can mean monitoring in both the PEI DCI and the paging DCI. It should be noted that when the terminal is configured to monitor the TRS availability indication information by the first manner and the second manner, the network will transmit the TRS availability indication information in both the PEI DCI and the paging DCI.

[0108] In some embodiments, the manner of listening to the TRS availability indication information can be determined according to the received configuration information. The manner of listening to the TRS availability indication information can also be determined according to a predetermined protocol. The manner of listening to the TRS availability indication information can also be determined according to a user-configured parameter, which is not limited herein.

[0109] In one embodiment, if the terminal is configured to listen to the TRS availability indication information in the first manner, a TRS availability indication field can be set in the PEI DCI.

[0110] In one embodiment, if the terminal is configured to listen to the TRS availability indication information in the second manner, the TRS availability indication field can be set in the paging DCI.

[0111] In one embodiment, if the terminal is configured to listen to the TRS availability indication information in the first manner and the second manner, the TRS availability indication field can be set in both the PEI DCI and the paging DCI.

[0112] It should be noted that the TRS availability indication field can be transmitted in the PEI DCI or the paging DCI. Here, the TRS availability indication field is a bitmap containing N bits, each bit corresponding to one TRS resource set group. If the TRS availability indication field indicates that a certain TRS resource set group is available, the starting time of the indication is the starting time of the first frame of the current default paging cycle in which the terminal receives the TRS availability indication. Illustratively, when a certain bit in the bitmap is valued as “1”, it indicates that the corresponding TRS resource set group is available; or when a certain bit is valued as “0”, it indicates that the corresponding TRS resource set group is unavailable.

[0113] In the embodiments of the present disclosure, it is determined that the terminal is configured to listen to a paging early indication (PEI); and the terminal listens to tracking reference signal (TRS) availability indication information in a predetermined manner, where the predetermined manner includes at least one of the following: a first manner of listening to the TRS availability indication information in the PEI; and a second manner of listening to the TRS availability indication information in paging DCI. Here, the terminal can listen to the TRS availability indication information in the first manner and / or the second manner, so that, after listening to the TRS availability indication information, it can be determined whether the network is transmitting the TRS. Compared with the case where it cannot be known whether the network is transmitting the TRS, the TRS can be received in time based on the TRS availability indication information, and the TRS is used to perform time-frequency domain tracking and synchronization operations in the RRC non-connected state, and the reliability of wireless communication is improved. In addition, the TRS availability indication information can be listened to in different manners, and the listening manner is more flexible.

[0114] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in some methods or related technologies in the embodiments of the present disclosure.

[0120] In one embodiment, it is determined that the terminal is configured to listen to the PEI DCI; it is determined that the terminal is configured to listen to the TRS availability indication information; and the TRS availability indication information is listened to in the PEI DCI.

[0121] Here, the TRS availability indication information is monitored in the PEI DCI, compared with monitoring the TRS availability indication information in the paging DCI, the terminal only needs to monitor the DCI once, that is, only needs to monitor the PEI DCI. Without the need to first monitor the PEI DCI and then monitor the paging DCI after being indicated to wake up. In this way, the power can be saved, and the endurance of the terminal can be improved.

[0122] Here, the manner of monitoring the TRS availability indication information can be determined according to the priority of monitoring the TRS availability indication information by the first manner and the priority of monitoring the TRS availability indication information by the second manner.

After determining that the terminal is configured to monitor the TRS availability indication information, the TRS availability indication information can be monitored by the first manner preferentially.

[0124] In one embodiment, the terminal can be configured to monitor the TRS availability indication information by the first manner or the second manner, and the priority of monitoring the TRS availability indication information by the first manner is less than the priority of monitoring the TRS availability indication information by the second manner. After determining that the terminal is configured to monitor the TRS availability indication information, the TRS availability indication information can be monitored by the second manner preferentially.

[0130] In one embodiment, the valid duration includes:

[0131] a duration configured by the base station;

[0132] or,

[0133] a duration determined according to a predetermined protocol.

[0134] Here, if the base station does not configure the duration, the valid duration is the duration determined according to the predetermined protocol.

[0135] In one embodiment, the valid duration is an integer multiple of a default paging cycle.

[0136] In one embodiment, the duration configured by the base station can be configured in units of a default paging cycle. For example, the duration configured by the base station can be a duration of 8 or 16 default paging cycles.

[0137] In one embodiment, the duration determined according to the predetermined protocol can be a duration of 3 default paging cycles.

[0138] Here, the start time at which the TRS availability indication information takes effect can be the start time of the first frame of the current default paging cycle in which the terminal receives the TRS availability indication information.

If the first duration information is received at a first time, and the second duration information is received at a second time within the duration range indicated by the first duration information, the effective duration of the TRS availability indication information is extended according to the duration indicated by the second duration information. Alternatively, if the second duration information is received at a first time, and the first duration information is received at a second time within the duration range indicated by the second duration information, the effective duration of the TRS availability indication information is extended according to the duration indicated by the first duration information.

[0148] In one embodiment, only one duration information is configured, which indicates a duration applicable to both TRS availability indication information transmitted in the PEI DCI and TRS availability indication information transmitted in the paging DCI. For example, the effective duration of TRS availability indication information intercepted in the PEI DCI can be determined based on this duration information, and the effective duration of TRS availability indication information intercepted in the paging DCI can also be determined based on this duration information.

[0149] In one embodiment, only the duration information of the TRS availability indication information transmitted in the paging DCI is configured, and the effective duration of the TRS availability indication information transmitted in the PEI DCI is determined based on the effective duration indicated by this duration information. For example, if the PEI DCI and its corresponding PO are in different DRX cycles, the effective duration of the TRS availability indication information detected in the PEI DCI can be the effective duration indicated by this duration information plus the duration of a default paging cycle; otherwise, the effective duration of the TRS availability indication information detected in the PEI DCI is the effective duration indicated by this duration information.

Here, the TRS availability indication field is a bitmap containing N bits, each bit corresponds to one TRS resource set group (TRS resource set group), and multiple bits correspond to multiple TRS resource set groups. If the TRS availability indication field indicates that a certain TRS resource set group is available, the starting time when the corresponding TRS availability indication information is valid is the starting time of the first frame of the current default paging cycle (default paging cycle) in which the terminal receives the TRS availability indication information.

[0157] In one embodiment, when the value of a certain bit of the TRS availability indication field is a first value (for example, “1”), the corresponding TRS resource set group is available; or when the value of a certain bit is a second value (for example, “0”), the corresponding TRS resource set group is unavailable. Here, available means that the TRS resource set group can be valid. If the terminal receives the TRS availability indication information indicating that the bit corresponding to a certain TRS resource set group is equal to “1”, the TRS resource set group is valid. It should be noted that the validity of the TRS availability indication information can include the validity of the TRS resource set group. Here, the validity duration of the TRS resource set group includes: the duration configured by the base station; or the duration determined according to the predetermined protocol.
