Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method for performing communication in a sleep state of a terminal and a terminal.
Background
In a newly designed 5G NR (New RAT/Radio, New Radio Access) system in the future, the system supports larger bandwidth and more complex services. The energy saving index of the terminal puts a definite requirement on the 5G NR system in ITU (International Telecommunication Union), and the terminal needs to reduce power loss as much as possible no matter when data is transmitted or in a standby state.
In the 5G NR system, the current operating states of the terminal are divided into three types: the terminal needs to monitor a paging signal in the first two states, namely, an RRC (Radio Resource Control) _ IDLE state, an RRC _ Inactive state, and an RRC _ Connected state, and when the terminal receives the paging signal, it indicates that there is data to be transmitted on the network side, and the terminal needs to enter the RRC _ Connected state to receive downlink data. On the other hand, in the RRC _ Connected state, the terminal needs to continuously monitor a Physical Downlink Control Channel (PDCCH) to obtain transmission information of a Physical Downlink Shared Channel (PDSCH). The continuous monitoring of the PDCCH inevitably causes fast power consumption of the terminal, so the terminal can be notified to enter a low power consumption mode, such as a sleep mode, when data arrives, a wake-up signal is sent, and if the terminal detects the wake-up signal, the terminal enters an activated state to detect and receive the PDSCH. However, after the wake-up signal is introduced, in a time period when the terminal enters the sleep mode and does not receive the wake-up signal, if the terminal does not communicate with the network side device for a long time, the terminal and the network side device may be out of synchronization.
In summary, the terminal may be out of synchronization with the network device after entering the sleep mode.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 2, the method for performing communication in a sleep state of a terminal according to the embodiment of the present invention includes:
Optionally, in the embodiment of the present invention, the terminal enters the sleep state when the following conditions are met:
for the terminals in the RRC _ IDLE state, the RRC _ Inactive state, and the RRC _ Connected state, if the terminal does not receive the paging message within the preset time period, the terminal enters the sleep state.
Here, the wake-up signal is sent to the terminal when the network side device determines that downlink data arrives; and after monitoring the wake-up signal, the terminal is switched from the sleep state to the wake-up state.
In step 202, the terminal performs at least one downlink operation in the process of monitoring the wake-up signal;
optionally, the downlink operation includes some or all of the following operations:
downlink synchronization, downlink measurement, system message acquisition, system message update monitoring, cell reselection, and wake-up area reselection.
The downlink synchronization operation is used for keeping the terminal and the network side equipment synchronized;
downlink measurement operation, system message acquisition operation, system message monitoring update operation, cell reselection operation and wake-up area reselection operation are used for keeping the terminal in a network state;
it should be noted that the keeping of the terminal in the network state according to the embodiment of the present invention means: the terminal can camp normally on the selected serving cell or the terminal can select a serviceable cell within a predefined time.
Downlink measurement operations include, but are not limited to: RRM (Radio Resource Management) measurement, L1CSI (Channel State Information) measurement.
Optionally, the terminal performs downlink operation in the following manner:
in the first mode, the terminal performs downlink operation at a preset position during the process of monitoring the wake-up signal.
The preset position can be notified to the terminal by the network side equipment; or a preset position is specified according to a protocol;
and, the terminal may perform one or more downlink operations in listening for the wake-up signal.
It should be noted that, when the network side notification is adopted, the network side device notifies the terminal of the location where the downlink operation is specifically performed, and when there are a plurality of preset locations, the network side device notifies the terminal of each location where the downlink operation is specifically performed;
alternatively, when a manner preset according to a protocol is adopted, one or more locations where downlink operations are performed are stored in advance in the terminal according to protocol specifications.
For example, the preset time is 20s, 35s, 45s, and 50s after the terminal enters the sleep state; that is, the terminal starts counting time from the sleep state, performs a first downlink operation at 20s, performs a second downlink operation at 35s, performs the first downlink operation at 45s, and performs the first downlink operation at 50 s.
In the second mode, the terminal periodically executes downlink operation in the process of monitoring the wake-up signal.
In implementation, the terminal wakes up from the sleep state at fixed intervals to perform downlink operation in the process of monitoring the wake-up signal.
Optionally, the terminal periodically performs downlink operation according to the following manner:
the terminal determines the position for executing downlink operation according to the configuration parameters; the terminal performs a downlink operation at the location where the downlink operation is performed.
That is, before each downlink operation is performed, it is necessary to first determine a location where the downlink operation is performed; after determining the location at which to perform the downlink operation, the downlink operation is performed at the determined location.
It should be noted here that the location where the downlink operation is performed may be a subframe or a time; and the location where the downlink operation is performed each time is a fixed duration d.
The configuration parameters are sent to the terminal by the network side equipment; or the configuration parameters are preset according to the protocol.
The configuration parameters include some or all of the following parameters:
a downlink operation period, a duration of performing a downlink operation within one period, and a start position of the downlink operation period.
Wherein, the downlink operation period is a fixed duration of an interval for the terminal to wake up from the sleep state every two times;
the time length for executing the downlink operation in one period means that the terminal executes the downlink operation in the time length;
the starting position of the downlink operation period is where the terminal performs the first downlink operation from.
In the embodiment of the invention, the terminal determines the position for executing the downlink operation by adopting the following modes:
the terminal determines the initial position for executing the downlink operation according to the configuration parameters;
and the terminal determines the position for executing the downlink operation according to the initial position and the time length for executing the downlink operation in the period.
For any position where a downlink operation is performed, it is necessary to first determine a starting position, and a position determined by adding a time period for performing the downlink operation from the starting position is a position where the downlink operation is performed.
For example, as shown in fig. 3, assuming that the determined starting position for performing the downlink operation is t1 and the duration for performing the downlink operation in one period is d, the duration d after the starting position t1 is t2, and the position between t1 and t2 is the position for performing the downlink operation.
Optionally, the terminal determines the starting position for performing the downlink operation in the following manner:
the terminal determines the initial position for executing downlink operation for the first time according to the configuration parameters; or
And the terminal determines the starting position for executing the downlink operation except for the first time according to the starting position for executing the downlink operation last time and the downlink operation period.
In implementation, the starting position for performing the downlink operation for the first time and the starting position for performing the downlink operation except for the first time are determined in different manners;
1. for a starting position where downlink operation is performed for the first time:
the terminal determines the initial position for executing downlink operation for the first time according to the configuration parameters;
specifically, the terminal determines a starting position for performing downlink operation for the first time according to one of the following ways:
mode 1, the terminal takes the starting position of the downlink operation period as the starting position for executing the downlink operation for the first time;
in this manner, the starting position of the downlink operation period refers to a specific position, and after the terminal acquires the starting position of the downlink operation period, the terminal directly starts to perform the first downlink operation at the position;
the starting position of the downlink operation period may be a specific subframe or a specific time, or may be in another form capable of characterizing a specific position, which is not limited in the embodiment of the present invention.
When the configuration parameters include the starting position of the downlink operation period, the terminal directly takes the starting position of the downlink operation period as the starting position for performing the downlink operation for the first time.
And 2, the terminal determines the initial position for executing the downlink operation for the first time according to the initial position for monitoring the wake-up signal and the downlink operation period.
The terminal determines the initial position for monitoring the awakening signal, and takes the position after the duration of the downlink operation period as the initial position for executing the downlink operation for the first time;
for example, as shown in fig. 4, the starting position of the terminal for listening for the wake-up signal is T0, and assuming that the downlink operation period is T, the position corresponding to T0+ T is the starting position for performing the downlink operation for the first time.
And in the mode 3, the terminal determines the initial position for executing the downlink operation for the first time according to the initial position for monitoring the wake-up signal and the initial position of the downlink operation period.
In this manner, the starting position of the downlink operation period is an offset value offset from the starting position of monitoring the wake-up signal to the starting position of first performing the downlink operation; after acquiring the starting position of the downlink operation period, the terminal calculates the starting position for executing the downlink operation for the first time according to the starting position of the monitoring wake-up signal and the starting position offset of the downlink operation period.
For example, as shown in fig. 5, the starting position of the terminal for monitoring the wake-up signal is t0, and assuming that the starting position of the downlink operation period acquired by the terminal is offset, the position corresponding to t0+ offset is the starting position of the first downlink operation.
2. For starting positions other than the first time at which downlink operations are performed:
determining a starting position for performing the downlink operation except for the first time according to the starting position for performing the downlink operation last time and the downlink operation period.
Specifically, for any downlink operation executed except for the first time, the starting position of the last downlink operation executed is added with the downlink operation period to be the starting position of the current downlink operation executed.
For example, as shown in fig. 6, assume that the starting position for performing downlink operation for the first time is T1, and the downlink operation period is T; when the starting position for performing the downlink operation for the second time is determined, the starting position for performing the downlink operation for the first time is added with the downlink operation T to obtain a position T2, and then the position T2 is used as the starting position for performing the downlink operation for the second time; when the starting position for performing the downlink operation for the third time is determined, the starting position T2 for performing the downlink operation for the second time is added to the downlink operation T to obtain the position T3, and then the position T3 is taken as the starting position for performing the downlink operation for the third time.
In practice, the terminal determines the location of each downlink operation performed by the terminal other than the first time by maintaining a first timer.
Optionally, the terminal starts a first timer at a starting position where the terminal last performed the downlink operation; wherein the set duration of the first timer is the downlink operation period; and after the first timer is overtime, the terminal determines that the current position is the initial position for executing the downlink operation this time.
It should be noted that, in the embodiment of the present invention, a first timer is first started at a starting position where a terminal performs a downlink operation for the first time, and a set duration of the first timer is a downlink operation period T, after the first timer expires, it indicates that the downlink operation period T has elapsed and a second downlink operation needs to be performed, so that a position where the first timer expires is taken as a starting position where the downlink operation is performed for the second time; and, after the first timer is overtime, the first timer is restarted immediately for monitoring the starting position for next downlink operation.
The embodiment of the invention adopts the method to determine the initial position for executing the downlink operation; after the initial position is determined, the terminal determines the position for executing the downlink operation according to the initial position and the time length for executing the downlink operation in one period; and the terminal performs the downlink operation at the determined position for performing the downlink operation.
Specifically, the terminal starts a second timer at a starting position for executing the downlink operation, and executes the downlink operation during the running of the second timer; wherein the set duration of the second timer is the duration of the downlink operation executed in the one period.
In implementation, the set duration of the second timer is not greater than the set duration of the first timer.
It should be noted here that, since the position within the fixed time length d is the position where the downlink operation is performed from the starting position where the downlink operation is performed; in the embodiment of the present invention, the second timer is started at the starting position for executing the downlink operation, and the set duration of the second timer is the duration for executing the downlink operation in one period, and during the running period of the second timer, the terminal is located at the position for executing the downlink operation, so that the terminal can execute the downlink operation during the running period of the second timer;
in practice, the terminal may perform downlink operation at any position during the operation of the second timer.
Specifically, as shown in fig. 7, the terminal periodically performs downlink operation by using the following steps:
it should be noted here that the terminal may perform the downlink operation at any time during the running of the second timer, and after the second timer expires, the terminal does not perform the downlink operation any more;
and 703, after the first timer is overtime, the terminal restarts the first timer and the second timer, and returns to 702.
For example, as shown in fig. 8, the terminal starts listening for the wake-up signal at time t0, and the starting position of listening for the wake-up signal is t 0.
Assuming that configuration parameters allocated by the network side device for the terminal include a downlink operation period T and a duration d for executing the downlink operation in one period, determining an initial position for executing the downlink operation for the first time for T0 according to the downlink operation period T and an initial position for monitoring the wake-up signal;
the starting position for the first time downlink operation is T0+ T, marked as T1 in fig. 8.
The terminal starts a first timer and a second timer at a position T1, wherein the duration of the first timer is a downlink operation period T, and the duration of the second timer is a duration d for performing downlink operation in one period.
The terminal performs a first downlink operation during the second timer running period (duration d);
it should be noted here that the terminal may perform the first downlink operation at any time when the second timer runs, and stop performing the downlink operation after the second timer expires.
After the first timer expires (the time period T has elapsed), the first timer and the second timer are restarted, which is now the starting position T0+2T for the second downlink operation, marked as T28 in fig. 8.
The terminal performs a second downlink operation during the second timer running period (duration d);
it should be noted here that the terminal may perform the second downlink operation at any time when the second timer runs, and stop performing the downlink operation after the second timer expires.
By analogy below, downlink operation is performed periodically.
Optionally, the terminal performs an uplink operation during the operation of the second timer;
the uplink operation is used for enabling the terminal to initiate interaction information with the network side equipment and/or respond to the interaction information sent by the network side equipment;
it should be noted that, during the running of the second timer, the terminal not only needs to perform downlink operation, but also needs to perform uplink operation; the downlink operation and the uplink operation may be performed simultaneously, or the downlink operation and the uplink operation may be performed in a time-division manner during the second timer is operated.
The uplink operation includes some or all of the following operations:
transmission of UL (Up Link) data, transmission of SR (Scheduling Request), and transmission of RACH (Random Access Channel).
The sending of UL data, the sending of SR and the sending of RACH are interactive information which is actively initiated by the terminal and is communicated with network side equipment.
In the embodiment of the invention, in the process of monitoring the wake-up signal, if the wake-up signal is monitored, the terminal stops the first timer and/or the second timer.
When the terminal receives the wake-up signal, if the first timer is running at the moment, the terminal stops the first timer; and if the second timer is running at the moment, the terminal stops the second timer.
It should be noted that, after the terminal monitors the wake-up signal, the terminal needs to switch from the sleep state to the wake-up state, and in the wake-up state, the terminal monitors a downlink-related signal in an existing manner and/or interacts with the access network device.
The terminal of the embodiment of the invention is used for passing in a sleep state, and two sets of receivers, namely a first receiver and a second receiver, are arranged in the terminal;
in an implementation, the terminal listens for the wake-up signal by the first receiver and performs downlink and/or uplink operations by the second receiver.
It should be noted here that, when the terminal is in the sleep state, only the first receiver is turned on for monitoring the wake-up signal; and when the terminal periodically performs the downlink operation and/or the uplink operation, the second receiver is turned on, and the downlink operation and/or the uplink operation are performed through the second receiver.
As shown in fig. 9, an overall flowchart of communication performed in the terminal sleep state according to the embodiment of the present invention.

the configuration parameters include some or all of the following parameters:
a downlink operation period, a duration of performing a downlink operation within one period, and a start position of the downlink operation period.
the manner for the terminal to determine the starting position for performing the downlink operation for the first time may be as follows:

Step 906, after the first timer is overtime, the terminal restarts the first timer and the second timer; and taking the current position as the starting position for next downlink operation; and returns to step 904;
Based on the same inventive concept, the embodiment of the present invention further provides a terminal, and since the principle of solving the problem of the terminal is similar to the method for performing communication in the terminal sleep state in the embodiment of the present invention, the implementation of the terminal may refer to the implementation of the method, and repeated details are not repeated.
