Background
Currently, development work of 5 th generation mobile communication system (5G) is actively underway. According to the future application requirements, the 5G system needs to support a variety of service scenarios, including EMBB (Enhanced Mobile Broadband), URLLC (Ultra-reliable and Low Latency Communications), and MMTC (Massive Machine Type of Communication). In the process of standard formulation, it is proposed that enhancement is needed in terms of terminal power saving, and in 3GPP (3 rd Generation Partnership Project) R14 standard, a focused study is made on terminal power saving in RRC-connected state, and in R16 standard, a further study is made on power saving in RRC-connected state, and certainly, how to save power in RRC _ IDLE state/RRC _ INACTIVE state.

To this end, an aspect of the present invention is to propose a method of grouping terminals.

In view of the above, according to an aspect of the present invention, a method for grouping terminals is provided, which is applied to a base station, and the method includes: configuring a wakeup period for each terminal respectively; and grouping each terminal according to the mobility of each terminal and the approximation degree of the wakeup cycle, wherein the approximation degree refers to that the mobility of the terminal is greater than a first threshold value and the wakeup cycles are consistent, or the mobility of the terminal is less than a second threshold value and the wakeup cycles are consistent, and the first threshold value is greater than the second threshold value.
The method for grouping the terminals, provided by the invention, has the advantages that the base station correspondingly configures the wakeup period for each terminal according to the mobility of the terminal, and further, all the terminals are grouped according to the similarity degree of the mobility and the wakeup period of each terminal and the mobility and the wakeup periods of other terminals. Specifically, terminals having mobility greater than a first threshold, i.e., having greater mobility and a uniform wake-up period, are grouped together, or terminals having mobility less than a second threshold, i.e., having less mobility and a uniform wake-up period, are grouped together. By adopting the technical scheme of the invention, the terminal grouping method is optimally designed, and the terminals with similar mobility and the same wake-up period are grouped into the same group, so that the multicast WUS mechanism can be applied, and the terminals can save more electricity.
In the above technical solution, the wakeup period refers to a time interval when the terminal receives the wakeup message, where the reception of the wakeup message may be received by a secondary communication interface of the terminal, and the secondary communication interface is defined to receive only the wakeup message at this time. It may also be received by the primary communication interface but separated in time from other data reception, all secondary communication interfaces may be the same physical entity as the primary communication interface, but may be logically separated or different physical entities, and the amount of power consumed by the secondary communication interface to receive the wake-up message is much less than the amount of power consumed by the primary communication interface, for example, only one tenth of the primary communication interface.
The mobility of the terminal can be classified into a high range: 350km/h to 500km/h, medium range: 350km/h to 120km/h, low range: 120km/h to 500km/h. If the mobility of the terminal is different, the doppler shift of the terminal is also different, so that the possibility of desynchronization on the network side is also different, the corresponding wake-up periods are different, and the terminal needs to keep time and frequency synchronization with the base station.

In any of the above technical solutions, preferably, the method further includes: and when the mobility of any terminal changes, sending a unicast wake-up signal frame to the terminal.
In the technical scheme, when the mobility of any terminal changes, namely the terminal leaves a certain terminal group allocated by the base station, the unicast wake-up signal frame can be independently sent to the terminal, so that the base station resource can be saved. It should be noted that the terminals may or may not be regrouped before the unicast wake-up signal frame is sent to the terminals alone.

Specifically, terminals having mobility greater than a first threshold, i.e., having greater mobility and a uniform wake-up period, are grouped together, or terminals having mobility less than a second threshold, i.e., having less mobility and a uniform wake-up period, are grouped together. By adopting the technical scheme of the invention, the terminal grouping method is optimally designed, and the terminals with similar mobility and the same wake-up period are grouped into the same group, so that the multicast WUS mechanism can be applied, and the terminals can save more electricity.
In the above technical solution, the wakeup period refers to a time interval when the terminal receives the wakeup message, where the reception of the wakeup message may be received by a secondary communication interface of the terminal, and the secondary communication interface is defined to receive only the wakeup message at this time.

Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention, taken in conjunction with the accompanying drawings and detailed description, is set forth below. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
Fig. 1 is a flowchart illustrating a method for grouping terminals according to an embodiment of the present invention. Wherein, the method comprises the following steps:
and 104, grouping each terminal according to the mobility of each terminal and the approximation degree of the wakeup cycle, wherein the approximation degree means that the mobility of the terminal is greater than a first threshold and the wakeup cycles are consistent, or the mobility of the terminal is less than a second threshold and the wakeup cycles are consistent, and the first threshold is greater than the second threshold.
The method for grouping the terminals, provided by the invention, has the advantages that the base station correspondingly configures the wakeup period for each terminal according to the mobility of the terminal, and further, all the terminals are grouped according to the similarity degree of the mobility and the wakeup period of each terminal and the mobility and the wakeup periods of other terminals. Specifically, terminals having mobility greater than a first threshold, i.e., having greater mobility and a uniform wake-up period, are grouped together, or terminals having mobility less than a second threshold, i.e., having less mobility and a uniform wake-up period, are grouped together. By adopting the technical scheme of the invention, the terminal grouping method is optimally designed, and the terminals with similar mobility and the same wake-up period are grouped into the same group, so that the multicast WUS mechanism can be applied, and the terminals can save more electricity.
In the above embodiment, the wake-up period refers to a time interval during which the terminal receives the wake-up message, where the reception of the wake-up message may be received by a secondary communication interface of the terminal, and the secondary communication interface is defined to receive only the wake-up message. It may also be received by the primary communication interface but separated in time from other data reception, all secondary communication interfaces may be the same physical entity as the primary communication interface but separated logically or may be different physical entities, and the amount of power consumed by the secondary communication interface to receive the wake-up message is much smaller than the amount of power consumed by the primary communication interface, for example, only one tenth of the primary communication interface.
The mobility of the terminal can be classified into a high range: 350km/h to 500km/h, medium range: 350km/h to 120km/h, low range: 120km/h to 500km/h. If the mobility of the terminal is different, the doppler shift of the terminal is also different, so that the probability of desynchronization on the network side is also different, and each wake-up period is different, and the terminal needs to keep synchronized in time and frequency with the base station.
For example, there are 6 terminals, the mobility of the terminal 1 is in a high range, the mobility of the terminal 2 is in a high range, the mobility of the terminal 3 is in a high range, the mobility of the terminal 4 is in a low range, the mobility of the terminal 5 is in a low range, and the mobility of the terminal 6 is in a medium range, and the wakeup periods of the terminal 1, the terminal 2, and the terminal 3 are consistent, the wakeup periods of the terminal 4 and the terminal 5 are consistent, and the wakeup periods of the terminal 6 are inconsistent with those of other terminals. Therefore, the terminal 1, the terminal 2, and the terminal 3 are divided into one group, the terminal 4 and the terminal 5 are divided into one group, and the terminal 6 is divided into one group.
In a specific embodiment, the terminal may be a network device such as a smart phone, a tablet computer, and a notebook computer.
Fig. 2 is a flowchart illustrating a method for grouping terminals according to another embodiment of the present invention. Wherein, the method comprises the following steps:
a group number is set for each terminal group and assigned to each terminal in the terminal group, step 206.
In this embodiment, a group number is set for each divided terminal, and the group numbers of each terminal group are different to indicate the division. And the group number is distributed to each terminal in the group, so that the terminal can clearly know the terminal group where the terminal is located, the terminal is ensured to realize the operation related to the terminal group, and the operation disorder is avoided. For example, as described above, 6 terminals have been divided into 3 terminal groups, and the 3 terminal groups are further sequentially numbered as group 1, group 2, and group 3, i.e., the group numbers of each group are different. And a group number is assigned to each terminal within the group, for group 1, "1" (group number) is assigned to terminal 1, terminal 2 and terminal 3; for group 2, "2" (group number) will be assigned to terminal 4 and terminal 5, and for group 3, "3" (group number) will be assigned to terminal 6.
Fig. 3 is a flowchart illustrating a method for grouping terminals according to still another embodiment of the present invention. Wherein, the method comprises the following steps:
In this embodiment, after the grouping is completed, a multicast wakeup signal frame is sent to each terminal in the terminal group, so that the terminal can save power even further. If the terminals are regrouped, the base station may also retransmit the multicast wakeup signal frame in order to ensure time synchronization between the terminals and the base station. For example, as described above, after the grouping is completed, the same or different multicast wakeup signal frames are transmitted to group 1, group 2, and group 3.
It should be noted that the wake-up signal frame received by the terminal may be received through the primary communication interface, or may be received through the secondary communication interface, where the secondary communication interface and the primary communication interface may be the same physical entity, but are logically separated, or may be different physical entities, and the power consumed by the secondary communication interface each time is much smaller than that consumed by the primary communication interface, for example, one tenth of the power consumed by the primary communication interface or less.
In any of the above embodiments of the present invention, preferably, the method further comprises: and when the mobility of any terminal changes, updating the wake-up period of the terminal, and regrouping the terminal according to the updated wake-up period.
It should be noted that after grouping each terminal, a group number may be set for each terminal group, and the group number may be assigned to each terminal in the terminal group.
In this embodiment, the terminal may have a greater mobility at a certain time and a lesser mobility at a certain time. Therefore, the wake-up period of the terminal is updated according to the change of the mobility of the terminal, and the terminal is grouped again after the change of the wake-up period, so that the accuracy of grouping after the terminal moves is ensured.
For example, as described above, when the mobility of the terminal 3 in the group 1 changes from the high range to the medium range and the wake-up period thereof becomes identical to the terminals 4 and 5 after the grouping is completed, the terminal 3 is newly grouped into the group 2, and further "2" (group number) may be assigned to the terminal 3.
In any of the above embodiments of the present invention, preferably, the method further comprises: and when the mobility of any terminal changes, sending a unicast wake-up signal frame to the terminal.
In this embodiment, when the mobility of any terminal changes, that is, after the terminal leaves a terminal group allocated by the base station, a unicast wake-up signal frame may be sent to the terminal alone, which may save base station resources. Before or after the unicast wake-up signal frame is sent to the terminal alone, the terminal may or may not be regrouped, and the group number is updated if the terminal is regrouped.
For example, as described above, after the grouping is completed, if the mobility of the terminal 3 in the group 1 changes, a unicast wake-up signal frame may be separately transmitted to the terminal 3. Before or after the unicast wakeup signal frame is transmitted to the terminal 3 alone, the terminal 3 may or may not be regrouped, and a new group number is transmitted to the terminal 3 when regrouped.
It should be noted that the terminal may receive the wake-up signal frame through the primary communication interface, or through the secondary communication interface, where the secondary communication interface and the primary communication interface may be the same physical entity, but are logically separated, or may be different physical entities, and the power consumed by the secondary communication interface each time is much smaller than that consumed by the primary communication interface, for example, one tenth or less of the power consumed by the primary communication interface.
In the second aspect of the present invention, an apparatus for grouping terminals is provided, which is applied to a base station, and fig. 4 shows a schematic diagram of an apparatus 40 for grouping terminals according to an embodiment of the present invention. Wherein the device 40 comprises:
a configuration module 402, configured to configure a wake-up period for each terminal respectively;
the grouping module 404 is configured to group the terminals according to the mobility of each terminal and an approximation degree of the wake-up period, where the approximation degree refers to that the mobility of the terminal is greater than a first threshold and the wake-up periods are consistent, or that the mobility of the terminal is less than a second threshold and the wake-up periods are consistent, and the first threshold is greater than the second threshold.
According to the terminal grouping device 40 provided by the invention, the base station correspondingly configures the wakeup period for each terminal according to the mobility of the terminal, and further, all terminals are grouped according to the similarity degree of the mobility and the wakeup period of each terminal and the mobility and the wakeup periods of other terminals. Specifically, terminals having mobility greater than the first threshold, that is, having greater mobility and the same wake-up period, are grouped together, or terminals having mobility less than the second threshold, that is, having less mobility and the same wake-up period, are grouped together. By adopting the technical scheme of the invention, the terminal grouping method is optimally designed, and the terminals with similar mobility and the same wake-up period are grouped into the same group, so that the multicast WUS mechanism can be applied, and the terminals can save more electricity.
In the above embodiment, the wake-up period refers to a time interval during which the terminal receives the wake-up message, where the reception of the wake-up message may be received by a secondary communication interface of the terminal, and the secondary communication interface is defined to receive only the wake-up message. It may also be received by the primary communication interface but separated in time from other data reception, all secondary communication interfaces may be the same physical entity as the primary communication interface, but may be logically separated or different physical entities, and the amount of power consumed by the secondary communication interface to receive the wake-up message is much less than the amount of power consumed by the primary communication interface, for example, only one tenth of the primary communication interface.
The mobility of the terminal can be classified into a high range: 350km/h to 500km/h, medium range: 350km/h to 120km/h, low range: 120km/h to 500km/h. If the mobility of the terminal is different, the doppler shift of the terminal is also different, so that the possibility of desynchronization on the network side is also different, the corresponding wake-up periods are different, and the terminal needs to keep time and frequency synchronization with the base station.
For example, there are 6 terminals, the mobility of the terminal 1 is a high range, the mobility of the terminal 2 is a high range, the mobility of the terminal 3 is a high range, the mobility of the terminal 4 is a low range, the mobility of the terminal 5 is a low range, and the mobility of the terminal 6 is a medium range, and the wake-up periods of the terminal 1, the terminal 2, and the terminal 3 are consistent, the wake-up periods of the terminal 4 and the terminal 5 are consistent, and the wake-up period of the terminal 6 is inconsistent with the wake-up periods of the other terminals. Therefore, the terminal 1, the terminal 2, and the terminal 3 are divided into one group, the terminal 4 and the terminal 5 are divided into one group, and the terminal 6 is divided into one group.
In a specific embodiment, the terminal may be a network device such as a smart phone, a tablet computer, and a notebook computer. The configuration module 402, the grouping module 404 may be a central processor or a base station controller, etc.
Fig. 5 is a schematic diagram of a terminal grouping apparatus 50 according to another embodiment of the present invention. Wherein the device 50 comprises:
a configuration module 502, configured to configure a wakeup period for each terminal respectively;
a grouping module 504, configured to group the terminals according to the mobility of each terminal and an approximation degree of an awake cycle, where the approximation degree refers to that the mobility of the terminal is greater than a first threshold and the awake cycles are consistent, or that the mobility of the terminal is less than a second threshold and the awake cycles are consistent, and the first threshold is greater than the second threshold;
a sending module 506, configured to send a multicast wakeup signal frame to each terminal in the terminal group.
In this embodiment, after the grouping is completed, a multicast wakeup signal frame is sent to each terminal in the terminal group, so that the terminal can save power even further. If the terminals are regrouped, the base station may also retransmit the multicast wakeup signal frame in order to ensure time synchronization between the terminals and the base station. For example, as described above, after the grouping is completed, the same or different multicast wakeup signal frames are transmitted to each terminal group.
It should be noted that the terminal may receive the wake-up signal frame through the primary communication interface, or through the secondary communication interface, where the secondary communication interface and the primary communication interface may be the same physical entity, but are logically separated, or may be different physical entities, and the power consumed by the secondary communication interface each time is much smaller than that consumed by the primary communication interface, for example, one tenth or less of the power consumed by the primary communication interface.
In one embodiment of the present invention, the grouping module 504 is further preferably configured to set a group number for each terminal group and assign the group number to each terminal in the terminal group.
In this embodiment, a group number is set for each divided terminal, and the group numbers of each terminal group are different to indicate the division. And the group number is distributed to each terminal in the group, so that the terminal can definitely know the terminal group where the terminal is located, the terminal is ensured to realize the operation related to the terminal group, and the operation disorder is avoided. For example, as described above, 6 terminals have been divided into 3 terminal groups, and the 3 terminal groups are further denoted as group 1, group 2, and group 3 in sequence, that is, the group numbers of each group are different. And a group number is assigned to each terminal within the group, for group 1, "1" (group number) is assigned to terminal 1, terminal 2 and terminal 3; for group 2, "2" (group number) will be assigned to terminal 4 and terminal 5, and for group 3, "3" (group number) will be assigned to terminal 6.
In an embodiment of the present invention, preferably, the grouping module 504 is further configured to update an awake period of any terminal when mobility of the terminal changes, and regroup the terminal according to the updated awake period.
In this embodiment, the terminal may have a greater mobility at a certain time and a lesser mobility at a certain time. Therefore, the wake-up period of the terminal is updated according to the change of the mobility of the terminal, and the terminal is grouped again after the change of the wake-up period, so that the accuracy of grouping after the terminal moves is ensured.
For example, as described above, when the mobility of the terminal 3 in the group 1 changes from the high range to the medium range and the wake-up period thereof becomes identical to the terminals 4 and 5 after the grouping is completed, the terminal 3 is newly grouped into the group 2, and further "2" (group number) may be assigned to the terminal 3.
In an embodiment of the present invention, preferably, the sending module 506 is further configured to send a unicast wake-up signal frame to the terminal when mobility of any terminal changes.
In this embodiment, when the mobility of any terminal changes, that is, after the terminal leaves a terminal group allocated by the base station, a unicast wake-up signal frame may be sent to the terminal alone, which may save base station resources. Before or after the unicast wake-up signal frame is sent to the terminal alone, the terminal may or may not be regrouped, and the group number is updated if the terminal is regrouped.
For example, as described above, after the grouping is completed, if the mobility of the terminal 3 in the group 1 changes, a unicast wake-up signal frame may be separately transmitted to the terminal 3. Before or after the unicast wakeup signal frame is transmitted to the terminal 3 alone, the terminal 3 may or may not be regrouped, and a new group number is transmitted to the terminal 3 when regrouped.
It should be noted that the terminal may receive the wake-up signal frame through the primary communication interface, or through the secondary communication interface, where the secondary communication interface and the primary communication interface may be the same physical entity, but are logically separated, or may be different physical entities, and the power consumed by the secondary communication interface each time is much smaller than that consumed by the primary communication interface, for example, one tenth or less of the power consumed by the primary communication interface.
