[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0045] Figure 1 is a schematic flow chart of a timer control method according to an embodiment of the present disclosure. The method shown in the embodiment can be applied to a user equipment, wherein the user equipment can be a mobile phone, a tablet computer, etc., and the user equipment can communicate with a base station.
[0046] As shown in Figure 1 , the timer control method can include the following steps:
[0047] In step S1, a message of a physical downlink control channel sent by a base station is received in a first cell.
[0048] In an embodiment, the user equipment can initiate a random access to the base station, for example, by sending a preamble (Preamble) of the random access to the base station, and can receive a message of a physical downlink control channel sent by the base station, and can determine whether the initiated random access is successful according to the received message of the physical downlink control channel. Wherein, the message of the physical downlink control channel can be a message in which the base station allocates a cell radio network temporary identifier (C-RNTI) to the user equipment.
[0049] In step S2, if it is determined according to the message of the physical downlink control channel that the random access initiated by the user equipment to the base station in a second cell is successful, a bandwidth part inactivity timer of an activated downlink bandwidth part of the first cell is started or restarted, and a bandwidth part inactivity timer of an activated downlink bandwidth part of the second cell is started or restarted.
[0050] In one embodiment, in case that it is determined according to the message of the physical downlink control channel that the random access initiated by the second cell to the base station is successful, if the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell has not been started, the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell can be started, and if the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell is running or stopped, the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell can be restarted. The same applies to the second cell, which will not be described here again.
[0051] The following embodiments are mainly used to illustrate the technical solutions of the present disclosure in case that the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell is stopped when it is determined according to the message of the physical downlink control channel that the random access initiated by the second cell to the base station is successful.
[0052] In one embodiment, when the user equipment initiates random access on a certain cell, the bandwidth part inactivity timer of the activated downlink bandwidth part of the cell is stopped.
[0053] However, for a certain type of cell, such as a secondary cell, i.e., a serving cell other than the primary cell and the primary secondary cell, after the user equipment initiates random access on the type of cell, the user equipment needs to receive the message of the physical downlink control channel sent by the base station on other types of cells, such as the primary cell or the primary secondary cell, in order to determine whether the initiated random access is successful.
[0054] In this case, the second cell (such as a secondary cell) where the user equipment initiates random access and the first cell (such as a primary cell or a primary secondary cell) where the message of the physical downlink control channel is received are different, and when the user equipment initiates random access, it will not only stop the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell, but also stop the bandwidth part inactivity timer of the activated downlink bandwidth part of the second cell.
[0055] And when it is determined according to the message of the physical downlink control channel that the random access is successful, if only the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell is started or restarted, the bandwidth part inactivity timer of the activated downlink bandwidth part of the second cell will remain stopped, so that the time of inactivity of the activated downlink bandwidth part cannot be recorded, resulting in the function of falling back to the default or initial bandwidth part in time.
[0056] According to the embodiment of the present disclosure, not only the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell can be started or restarted, but also the bandwidth part inactivity timer of the activated downlink bandwidth part of the second cell can be started or restarted, so that the bandwidth part inactivity timer of the stopped activated downlink bandwidth part of the first cell and the bandwidth part inactivity timer of the stopped activated downlink bandwidth part of the second cell can be started or restarted, ensuring that the inactivity time of the activated downlink bandwidth part of the first cell and the inactivity time of the activated downlink bandwidth part of the second cell can be timed, and further ensuring that the function of the activated downlink bandwidth part of the first cell and the function of the activated downlink bandwidth part of the second cell can be respectively rolled back to the default or initial bandwidth part function in time.
[0057] Optionally, the first cell and the second cell are different cells.
[0058] Optionally, the first cell and the second cell are the same cell.
[0059] In one embodiment, Figure 1 The embodiment shown can be applicable to the case where the first cell and the second cell are different cells, and can also be applicable to the case where the first cell and the second cell are the same cell. In the case where the first cell and the second cell are the same cell, the bandwidth part inactivity timer of the activated downlink bandwidth part only needs to be started or restarted once for the same cell.
[0060] Figure 2 is a schematic flow chart of another timer control method according to an embodiment of the present disclosure. As shown in Figure 2 Based on the embodiment shown in Figure 1 The timer control method further includes:
[0061] In step S3, before the first cell receives the message of the physical downlink control channel sent by the base station, it is determined whether the user equipment is configured with the bandwidth part inactivity timer;
[0062] In the case where the user equipment is configured with the bandwidth part inactivity timer, if it is determined according to the message of the physical downlink control channel that the random access initiated by the second cell to the base station is successful, the bandwidth part inactivity timer of the activated downlink bandwidth part of the first cell is started or restarted, and the bandwidth part inactivity timer of the activated downlink bandwidth part of the second cell is started or restarted.
[0063] In one embodiment, the base station can configure a bandwidth portion inactive timer for the user equipment. Before the user equipment receives the physical downlink control channel message sent by the base station in the first cell, it can determine whether it has been configured with a bandwidth portion inactive timer. If it has been configured with a bandwidth portion inactive timer, it means that when the active downlink bandwidth portion of all serving cells of the user equipment is inactive for a longer than a preset duration, the function of the active downlink bandwidth portion needs to fall back to the function of the default or initial bandwidth portion.
[0064] Therefore, only when the random access initiated by the second cell to the base station is successfully determined according to the message of the physical downlink control channel, it is necessary to start or restart the inactive timer of the active downlink bandwidth portion of the first cell, and start or restart the inactive timer of the active downlink bandwidth portion of the second cell, to ensure that the functions of the active downlink bandwidth portion of the first cell and the active downlink bandwidth portion of the second cell are rolled back to the default or initial bandwidth portion functions in a timely manner.
[0065] It should be noted that, based on Figure 2 In the embodiment shown, when a user equipment establishes a communication connection with a base station, the base station can configure a bandwidth partial inactive timer for the user equipment. For example, if the bandwidth partial inactive timer is configured for the user equipment, the base station can also indicate the association relationship between the bandwidth partial inactive timer and the user equipment to the user equipment.
[0066] Figure 3 This is a schematic flowchart illustrating yet another timer control method according to an embodiment of the present disclosure.
[0067] like Figure 3 As shown, in Figure 1 Based on the illustrated embodiment, the timer control method further includes:
[0068] In step S4, before the first cell receives the physical downlink control channel message sent by the base station, it is determined whether the first cell and the second cell are configured with a bandwidth portion inactive timer.
[0069] Wherein, if the first cell and the second cell are configured with bandwidth partial inactive timers, if it is determined from the physical downlink control channel message that the random access initiated by the second cell to the base station is successful, the active downlink bandwidth partial inactive timer of the first cell is started or restarted, and the active downlink bandwidth partial inactive timer of the second cell is started or restarted.
[0070] In one embodiment, the base station can configure a bandwidth part inactivation timer for a cell, before the user equipment receives a message of a physical downlink control channel sent by the base station in a first cell, the user equipment can determine whether the first cell and a second cell are configured with the bandwidth part inactivation timer, if the first cell and the second cell are configured with the bandwidth part inactivation timer, it means that the function of the activated downlink bandwidth part of the first cell and the second cell needs to be rolled back to the function of the default or initial bandwidth part when the inactivity duration is greater than a preset duration.
[0071] Therefore, when it is determined according to the message of the physical downlink control channel that the random access initiated by the second cell to the base station is successful, the bandwidth part inactivation timer of the activated downlink bandwidth part of the first cell needs to be restarted, and the bandwidth part inactivation timer of the activated downlink bandwidth part of the second cell needs to be started or restarted, so as to ensure that the function of the activated downlink bandwidth part of the first cell and the function of the activated downlink bandwidth part of the second cell are timely rolled back to the function of the default or initial bandwidth part respectively.
[0072] It should be noted that, based on Figure 3 As shown in the embodiment, when the user equipment establishes a communication connection with the base station, the base station can configure a bandwidth part inactivation timer for the user equipment, for example, the bandwidth part inactivation timer is configured for the first cell, and then the base station can also indicate the user equipment the association relationship between the bandwidth part inactivation timer and the first cell.
