Those of ordinary skill in the art may know that, with the evolution of the system architecture and the occurrence of a new service scene, the technical solutions provided in the embodiments of the present disclosure are also applicable to similar technical problems.

For a TRS with a short period, if the TRS period is changed by changing the configuration period of the network device for the channel state information (CSI) reference signal (RS), not only the load of the network signaling is affected, but also the power consumption of the network device is increased.

The method and apparatus for determining a tracking reference signal period provided in the present disclosure are described in detail below with reference to the accompanying drawings.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for determining a tracking reference signal period according to some embodiments of the present disclosure, and the method is performed by a network device. As shown in FIG. 2, the method may include, but is not limited to, the following steps.

In step 21, first indication information is sent, on a physical layer, to a terminal device, where the first indication information is used to indicate a change period of a tracking reference signal (TRS).

In the present disclosure, considering that the period for performing CSI RS configuration by using the radio resource control (RRC) message is longer that a short TRS period, in order to avoid increasing of the signaling load due to indicating the change period of the TRS to the terminal device by changing the configuration period of the RRS message, the change period of the TRS is indicated to the terminal device by using the physical layer signaling.

In some embodiments, the network device may add the first indication information in an available indication of the TRS of the physical layer, so as to indicate the change period of the TRS.

Alternatively, the network device may also add the first indication information to downlink control information (DCI) of the physical layer, so as to indicate the change period of the TRS.

It can be understood that in the present disclosure, the TRS period can be updated by only adding the first indication information for indicating the change period of the TRS in the signaling of the physical layer, without changing the configuration period of the RRS message of the high layer, thus reducing the power consumption of the network device.

By implementing the embodiments of the present disclosure, the network device indicates the change period of the tracking reference signal (TRS) to the terminal device on the physical layer. Therefore, the process of updating the TRS period does not affect the network signaling, and reduces the impact of updating the TRS period on the power consumption of the network device.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a method for determining a tracking reference signal period according to some embodiments of the present disclosure, and the method is performed by a network device. As shown in FIG. 3, the method may include, but is not limited to, the following steps.

In step 31, first indication information is sent to a terminal device through an available indication of the TRS, where the terminal device is in an idle state or an inactive state.

Among them, the first indication information is used to indicate a change period of the tracking reference signal (TRS).

In some embodiments, the change period of the TRS indicated by the first indication information may be a specific period size after the TRS changes, for example, 10 ms, 20 ms, or the like, which is not limited in the present disclosure.

Alternatively, the change period of the TRS indicated by the first indication information may also be corresponding position information of the period after the TRS changes in a preset parameter pair, and then the terminal device may determine the change period of the TRS from the preset parameter pair according to the position information.

It may be understood that the network device sends the first indication information to the terminal device through the available indication of the TRS of the physical layer to indicate the change period of the TRS, and the TRS period is updated without changing the configuration period of the RRS message of the high layer, thus reducing the power consumption of the network device.

By implementing the embodiments of the present disclosure, when the terminal device is in an idle state or an inactive state, the network device indicates the change period of the tracking reference signal (TRS) to the terminal device through the available indication of the TRS. Therefore, the process of updating the TRS period does not affect the network signaling, and reduces the impact of updating the TRS period on the power consumption of the network device.

Referring to FIG. 4, FIG. 4 is a schematic flowchart of a method for determining a tracking reference signal period according to some embodiments of the present disclosure, and the method is performed by a network device.

In step 41, first indication information is sent to a terminal device through a downlink control indication (DCI), where the terminal device is in a connected state.

Among them, the first indication information is used to indicate a change period of the tracking reference signal (TRS).

Alternatively, the change period of the TRS indicated by the first indication information may also be corresponding position information of the change period of the TRS in a preset parameter pair, and then the terminal device may determine the change period of the TRS from the preset parameter pair according to the position information.

It may be understood that the network device sends the first indication information to the terminal device through the DCI of the physical layer to indicate the change period of the TRS, and the TRS period is updated without changing the configuration period of the RRS message of the high layer, thus reducing the power consumption of the network device.

By implementing the embodiments of the present disclosure, when the terminal device is in a connected state, the network device indicates the change period of the tracking reference signal (TRS) to the terminal device through the downlink control indication (DCI). Therefore, the process of updating the TRS period does not affect the network signaling, and reduces the impact of updating the TRS period on the power consumption of the network device.

In some embodiments, the network device may determine the length n of the first preset bit and the position of the first preset bit in the available indication of the TRS according to a protocol agreement.

In some embodiments, the network device may determine the value of the first preset bit in the available indication of the TRS according to the size of the change period of the TRS in a binary coding manner.

For example, if the size of the change period of the TRS is 5 ms, the corresponding value of the first preset bit may be 101; and if the size of the change period of the TRS is 10 ms, the corresponding value of the first preset bit may be 10010, etc., which is not limited in the present disclosure.

In step 52, first indication information is sent to a terminal device through an available indication of the TRS, where the terminal device is in an idle state or an inactive state.

Among them, the first indication information is used to indicate a change period of the tracking reference signal (TRS).

It may be understood that the first indication information in the embodiment may be the value of the first preset bit.

Among them, for the specific implementation of step 52, reference may be made to the detailed description in other embodiments of the present disclosure, and details are not described here again.

By implementing the embodiments of the present disclosure, the network device determines the value of the first preset bit in the available indication of the TRS according to the size of the change period of the TRS; and then, in a case that the terminal device is in an idle state or an inactive state, the network device indicates the change period of the TRS to the terminal device through the available indication of the TRS indication. Therefore, the process of updating the TRS period does not affect the network signaling, and the impact of updating the TRS period on the power consumption of the network device is reduced.

In some embodiments, the preset parameter pair may be configured by higher layer signaling, and include a set of a normally configured TRS period and a power saving TRS period. For example, the preset parameter pair may be [5 ms, 20 ms], where 5 ms may be a normally configured TRS period, and 20 ms may be a power saving TRS period. This is not limited in the present disclosure.

Among them, the second preset bit in the available indication of the TRS may be an information domain of nbit in the available indication of the TRS. For example, the nbit may be 1 bit, 2 bits, or the like.

In step 81, a value of a second preset bit in the DCI is determined according to a position of the change period of the TRS in a preset parameter pair.

Among them, the preset parameter pair may include two TRS periods of different sizes.

In some embodiments, the second preset bit may be an information domain of a nbit in the DCI. For example, the nbit may be 1 bit, 2 bits, or the like.

Among them, the service type may be classified into a high-reliability service, a normal service, a low-reliability service according to a reliability degree of the service, which is not limited in the present disclosure.

In some embodiments, the network device may configure a relatively short TRS period for a high-reliability service, and configure a relatively short TRS period for a normal service or a low-reliability service, which is not limited in the present disclosure.

By implementing the embodiments of the present disclosure, in a case that the terminal device is in a connected state, the first indication information is received through the DCI, and then the size of the change period of the TRS is determined according to the value of the first preset bit in the DCI. Therefore, the process of updating the TRS period does not affect the network signaling, and the impact of updating the TRS period on the power consumption of the network device is reduced.

Referring to FIG. 14, FIG. 14 is a schematic flowchart of a method for determining a tracking reference signal period according to some embodiments of the present disclosure, and the method is performed by a terminal device. As shown in FIG. 14, the method may include, but is not limited to, the following steps.

In step 141, in a case that the terminal device is in a connected state, first indication information is received through a downlink control indication (DCI).

Among them, the first indication information is used to indicate a change period of the tracking reference signal (TRS).

In some embodiments, the change period of the TRS indicated by the first indication information included in the DCI may be corresponding position information of the change period of the TRS in a preset parameter pair.

Among them, the preset parameter pair may include two TRS periods of different sizes.

In step 142, second indication information sent by a network device is received, where the second indication information is used to indicate a preset parameter pair.

In step 143, a position of the change period of the TRS in the preset parameter pair is determined according to a value of a second preset bit in the DCI.

In some embodiments, the terminal device may determine a length n of the second preset bit and the position of the second preset bit in the DCI according to a protocol agreement or an indication of the network device, which is not limited in the present disclosure.

For example, if the length of the second preset bit in the DCI is 1 bit, and the value is 1, the change period of the TRS may be a period value corresponding to the second position in the preset parameter pair. Alternatively, if the length of the second preset bit is 2 bits and the value is 11, the change period of the TRS may be a period value corresponding to the fourth position in the preset parameter pair.

It should be noted that the foregoing examples are merely schematic descriptions, and should not serve as a specific limitation of the second preset bit in the present disclosure.

By implementing the embodiments of the present disclosure, in a case that the terminal device is in a connected state, the first indication information is received through the DCI, then the preset parameter pair sent by the network device is received, and finally, the position of the change period of the TRS in the preset parameter pair is determined according to the value of the second preset bit in the available indication of the TRS, so as to determine the change period of the TRS. Therefore, the process of updating the TRS period does not affect the network signaling, and the impact of updating the TRS period on the power consumption of the network device is reduced.
