Description

Discontinuous reception control method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a control method and a terminal for discontinuous reception.

Background

According to the current protocol of the mobile communication network, the network side device can only configure a Discontinuous Reception (DRX) configuration for a terminal (User Equipment, UE), and in a certain scenario, for example: when the UE operates in both the licensed frequency band and the unlicensed frequency band, the UE may have fewer opportunities to monitor the PDCCH in the serving cell of the unlicensed frequency band than in the serving cell of the licensed frequency band (licensed band). Currently, a UE generally increases a time duration for monitoring a Physical Downlink Control Channel (PDCCH) to achieve a similar opportunity for monitoring the PDCCH on a serving cell in an unlicensed frequency band as that on a serving cell in a licensed frequency band (licensed band). However, using a DRX configuration that increases the duration of monitoring the PDCCH may cause the UE to monitor the PDCCH more frequently on other serving cells, resulting in an increased probability that the UE will blindly detect the PDCCH without data, thereby causing unnecessary power waste for the UE.

Therefore, the UE has the problem of unnecessary power waste at present.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network-side device 12, where the terminal 11 and the network-side device 12 can communicate with each other through a network.

In this embodiment of the present invention, the terminal 11 may also be referred to as a UE (User Equipment), and when the implementation is specific, the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and a specific type of the terminal 11 is not limited in this embodiment of the present invention.

The network side device 12 may be a base station, a relay, an access point, or the like. The base station may be a base station of 5G and later versions (e.g., a 5G NR NB), or a base station in another communication system (e.g., an evolved Node B (eNB)), and it should be noted that the specific type of the network side device 12 is not limited in this embodiment of the present invention.

Referring to fig. 2, fig. 2 is a flowchart of a control method for discontinuous reception according to an embodiment of the present invention. The control method of discontinuous reception of this embodiment is applied to a terminal, and the method includes:

step 201, receiving a Discontinuous Reception (DRX) command (command) message sent by a network side device in a scheduled cell under the condition that a terminal is configured with cross-carrier scheduling and uses at least two sets of DRX configurations;

step 202, applying the DRX command message to a target DRX configuration of the at least two sets of DRX configurations;

the target DRX configuration is a DRX configuration which has an association relation with the scheduling cell; the scheduling cell is a serving cell in which the terminal monitors a physical downlink control channel.

Here, since the terminal is configured with cross-carrier scheduling and uses at least two sets of DRX configurations, when the terminal has a similar opportunity to monitor the PDCCH between the scheduled cell and the scheduling cell, the MAC entity (MAC entry) of the terminal respectively uses the DRX configuration associated with the scheduled cell and the DRX configuration associated with the scheduling cell, so that the duration for the terminal to monitor the PDCCH in the scheduling cell is independent from the duration for the terminal to monitor the PDCCH in the scheduled cell.

In addition, the terminal applies the DRX command received by the dispatched cell to the DRX configuration associated with the dispatched cell, and realizes timely change of the relevant configuration in the DRX configuration associated with the dispatched cell, so that the time for the terminal to monitor the PDCCH in the dispatched cell is more reasonable, and the electric quantity of the terminal is further saved.

The scheduling cell is a serving cell in which a terminal monitors a Physical Downlink Control Channel (PDCCH), and the PDCCH may transmit a message for scheduling a Physical Downlink shared Channel (PDCCH) carrying a DRX command message.

The DRX command message is applied to the target DRX configuration of the at least two sets of DRX configurations, and the terminal adjusts the relevant configuration of the target DRX configuration through the DRX command message, so that the time for the terminal to monitor the PDCCH in the scheduling cell is more reasonable, and the electric quantity of the terminal is further saved.

Wherein, each set of DXR configuration in the at least two sets of DRX configurations may include configuration of at least one of:

a DRX duration timer (DRX-onDurationTimer);

a DRX deactivation timer (DRX-inactivity timer);

a DRX short cycle timer (DRX-ShortCycleTimer);

short DRX Cycle (short DRX Cycle);

long DRX Cycle, etc.

As shown in fig. 3, the DRX cycle includes an on-duration long term and a sleep period.

Optionally, the applying the DRX command message to the target DRX configuration of the at least two sets of DRX configurations includes:

stopping the DRX duration timer and the DRX deactivation timer in the target DRX configuration in response to the DRX command message.

The terminal can stop the DRX duration timer and the DRX deactivation timer in the target DRX configuration in response to the DRX command message, so that when the duration of the DRX deactivation timer is set to be too long, the terminal can avoid unnecessary power consumption caused by the fact that the terminal still keeps monitoring downlink subframes because the timer is not overtime after data transmission of a network side is finished by stopping the DRX duration timer and the DRX deactivation timer in time, and power saving of the terminal is realized.

Optionally, after stopping the DRX duration timer and the DRX deactivation timer in the target DRX configuration in response to the DRX command message, the method further includes:

under the condition that the target DRX configuration is provided with a short DRX period, if the DRX command message is a DRX command Media Access Control (MAC) CE, controlling the terminal to start or restart a DRX short period timer in the target DRX configuration at a first Orthogonal Frequency Division Multiplexing (OFDM) symbol after the terminal receives the DRX command MAC CE, and using the short DRX period; if the DRX command message is a long DRX command MAC CE, controlling the terminal to stop a DRX short period timer in the target DRX configuration at a first OFDM symbol after the terminal receives the long DRX command MAC CE; alternatively, the first and second electrodes may be,

and using the long DRX period set by the target DRX configuration under the condition that the short DRX period is not set by the target DRX configuration.

Here, since the long DRX cycle is useful for extending the battery usage time of the terminal and the shorter DRX cycle is useful for faster response, the terminal can also perform a target operation on the DRX short cycle timer in the target DRX configuration by setting the short DRX cycle in the target DRX configuration, and implement flexible switching of the DRX cycle between the long DRX cycle and the short DRX cycle in the target DRX configuration by using the long DRX cycle set by the target DRX configuration in the case where the target DRX configuration is not set with the short DRX cycle, thereby achieving a balance between power saving and scheduling flexibility of the terminal.

Of course, the application of the DRX command message to the target DRX configuration in the at least two sets of DRX configurations is not limited to the adjustment of the above configurations, and may also be the adjustment of other configurations such as other timers in the DRX configurations, which is not described herein again.

It should be noted that, the above-mentioned control terminal starts or restarts the DRX short cycle timer in the target DRX configuration at the first OFDM symbol after it receives the DRX Command MAC CE, which may be the control terminal starts or restarts the DRX short cycle timer at the starting time of the first OFDM symbol after it receives the DRX Command MAC CE; similarly, the terminal may stop the DRX short cycle timer in the target DRX configuration at the first OFDM symbol after receiving the long DRX Command MAC CE, or the terminal may stop the DRX short cycle timer in the target DRX configuration at the starting time of the first OFDM symbol after receiving the long DRX Command MAC CE.

The terminal is pre-configured with at least two sets of DRX configurations, wherein the terminal can be only configured with two sets of DRX configurations, and different DRX configurations in the two sets of DRX configurations have an association relation with a scheduled cell and different service cells in the scheduled cell; or, more than two sets of DRX configurations may be preconfigured in the terminal, and the scheduled cell and the scheduling cell are respectively associated with at least one set of DRX configurations, and the DRX configuration associated with the scheduled cell is different from the DRX configuration associated with the scheduling cell.

Optionally, the at least two sets of DRX configurations include a first DRX configuration and a second DRX configuration, the first DRX configuration is associated with the scheduled cell, the second DRX configuration is associated with the scheduling cell, the target DRX configuration is the second DRX configuration, that is, the scheduled cell and the scheduling cell are respectively and directly associated with different DRX configurations, and the terminal may apply the DRX command message to the DRX configuration directly associated with the scheduling cell.

In a wireless communication system (e.g. 5G NR), the Bandwidth of the terminal may be dynamically changed, that is, the network side device may configure a Bandwidth Part (BWP) for the terminal according to the traffic size of the terminal, for example: at the first moment, the traffic of the terminal is larger, and the system configures a large bandwidth (BWP 1) for the terminal; at the second moment, the traffic of the terminal is smaller, and the system configures a small bandwidth (BWP2) for the terminal to meet the basic communication requirement; at the third moment, the system finds that there is wide-range frequency selective fading in the bandwidth of BWP1, or there is a shortage of resources in the frequency range of BWP1, and then configures a new bandwidth (BWP 3) for the terminal, so that the terminal can switch to the appropriate bandwidth to operate under the condition of adapting to the service requirement of the terminal, thereby achieving the reduction of power consumption.

Therefore, the DRX configuration in the terminal has an association relationship with the serving cell, which may be that the DRX configuration is associated with a bandwidth part in the serving cell, that is: optionally, the at least two sets of DRX configurations include a third DRX configuration and a fourth DRX configuration, where the third DRX configuration is associated with the first bandwidth part of the scheduled cell; and the fourth DRX configuration is associated with the second bandwidth part in the scheduling cell, and the target DRX configuration is the fourth DRX configuration.

The terminal receives the DRX command message on the scheduled cell, and receives the DRX command message on a Physical Downlink Shared Channel (PDSCH) transmitted by the scheduled cell, or specifically, receives the DRX command message on the PDSCH transmitted by the BWP of the scheduled cell.

Optionally, the receiving a DRX discontinuous reception command message sent by the network side device in the scheduled cell includes:

a DRX command message is received on a first bandwidth portion.

In this way, by receiving the DRX command message on the first bandwidth portion of the scheduled cell, the terminal's occupation of the spectrum resources of the scheduling cell for receiving the DRX command message can be reduced.

It should be noted that, in the case that the scheduled cell is configured with a plurality of bandwidth parts, the first bandwidth part may be any bandwidth part associated with a DRX configuration preconfigured by the terminal, and is not limited herein.

In a wireless communication system, in some scenarios, when the channel quality of some cells is not good or the channel blocking rate is high, a network side device may configure cross-carrier scheduling for a terminal. The cross-carrier scheduling is to configure a control channel in a cell with better channel quality (i.e., a scheduling cell, such as a primary cell), and perform cross-carrier scheduling on data of other cells (i.e., scheduled cells, such as secondary cells) through the control channel. The scheduling cell can schedule its own cell and one or more other scheduled cells, and the scheduled cell has no PDCCH and can only be scheduled by the scheduling cell.

Optionally, the control information is transmitted in the physical downlink control channel, and the control information is used to schedule a physical downlink shared channel carrying the DRX command message.

Here, the network side device may configure cross-carrier scheduling, that is, data working in the scheduling cell may be scheduled, and the terminal may implement scheduling of a physical downlink shared channel of the scheduled cell, which carries the DRX command message, through the control information received in the scheduling cell, so that the terminal receives the DRX command message in the scheduled cell, thereby improving resource utilization of a traffic channel of the scheduling cell, and improving performance of the wireless communication system.

The receiving of the physical downlink control channel in the scheduling cell may be that the network side device sends a PDCCH indicating downlink transmission to the terminal in the scheduling cell.

In addition, the terminal may monitor the PDCCH on the bandwidth part of the serving cell, i.e.: optionally, the method for controlling discontinuous reception further includes:

and monitoring a physical downlink control channel on the second bandwidth part, wherein control information is transmitted in the physical downlink control channel, and the control information is used for scheduling a physical downlink shared channel carrying the DRX command message.

Therefore, the resource utilization rate of the service channel of the scheduling cell can be improved, and the waste of the electric quantity of the terminal can be further reduced.

It should be noted that the scheduled cell and the scheduling cell may be cells in the coverage area of the same network side device, or may be cells in coverage areas of different network side devices, and are not limited herein.

In addition, optionally, one of the scheduled cell and the scheduling cell is a cell in an authorized frequency band, and the other is an unlicensed frequency band; alternatively, the first and second electrodes may be,

the scheduled cell and the scheduling cell are both cells of authorized frequency bands; alternatively, the first and second electrodes may be,

the scheduled cell and the scheduling cell are both cells of an unlicensed frequency band.

Here, in the case that the scheduled cell is any one of a cell in a licensed frequency band and a cell in an unlicensed frequency band, and the scheduling cell is any one of a cell in a licensed frequency band and a cell in an unlicensed frequency band, both the MAC entity (MAC entry) of the terminal may implement to use the DRX configuration associated with the scheduled cell and the DRX configuration associated with the scheduling cell, respectively, so as to implement power saving, especially in the case that the scheduled cell is a cell in an unlicensed frequency band and the scheduling cell is a cell in a licensed frequency band.

Of course, when the scheduled cell and the scheduling cell are both the serving cell of the authorized frequency band or the serving cell of the unauthorized frequency band, the DRX command message is applied to the DRX configuration associated with the scheduling cell, so that the relevant configuration in the DRX configuration associated with the scheduling cell can be changed in time, the monitoring of the PDCCH can be stopped in time after the data transmission of the network side is completed, and thus, the power consumption of the terminal can be saved.

To better explain the control method of discontinuous reception provided by the embodiment of the present invention, an example a and an example b are provided herein for explanation, specifically as follows:

in an example, when the network side device configures cross-carrier scheduling and the serving cell 1 schedules the cell 2, after the terminal receives the DRX command MAC CE or long DRX command MAC CE on the serving cell 2, the terminal applies the received DRX command MAC CE or long DRX command MAC CE to the DRX configuration associated with the serving cell 1.

Assuming that a current network side device configures a plurality of sets of separately set DRX configurations for a terminal, the plurality of sets of DRX configurations are cell-specific (cell-specific), that is, the DRX configurations are directly associated with cells, and the current network side device configures cross-Carrier scheduling, wherein a serving cell 1 operating on a Carrier Cell (CC) 1 in a licensed frequency band can schedule a serving cell 2 operating on a CC 2 in an unlicensed frequency band, the serving cell 1 and the DRX configuration 1 are associated, and the serving cell 2 and the DRX configuration 2 are associated. The terminal may monitor the PDCCH indicating downlink transmission on the serving cell 1, the control information carried by the PDCCH may schedule the cell 2, and the terminal receives the DRX command message on the serving cell 2, then:

in case the terminal receives a DRX command MAC CE or a long DRX command MAC CE on the serving cell 2, the serving cell 1 transmitting the PDCCH stops the DRX duration timer in the associated DRX configuration 1 and stops the DRX deactivation timer in this DRX configuration 1.

Under the condition that the terminal receives a DRX command MAC CE on a service cell 2, if a DRX configuration 1 is provided with a short DRX period, starting or restarting a DRX short period timer in the DRX configuration at the starting moment of a first OFDM symbol after the terminal receives the DRX command MAC CE, and using the short DRX period; if DRX configuration 1 is not set with a short DRX cycle, DRX configuration 1 uses a long DRX cycle.

Under the condition that the terminal receives a long DRX command MAC CE on a service cell 2, if a DRX configuration 1 sets a short DRX period, stopping a DRX short period timer in the DRX configuration 1 at the starting time of a first OFDM symbol after the long DRX command MAC CE is received; if DRX configuration 1 is not set with a short DRX cycle, DRX configuration 1 uses a long DRX cycle.

In example two, when the network side device configures cross-carrier scheduling, and the serving cell 1 schedules the cell 2, and the network side device transmits a PDCCH on the BWP1 of the serving cell 1, after receiving a DRX command MAC CE or a long DRX command MAC CE in a PDSCH transmitted on the BWP2 of the serving cell 2, the terminal applies the received DRX command MAC CE or long DRX command MAC CE to a DRX configuration associated with the BWP 1.

Assume that the current network side device configures multiple sets of separately set DRX configurations for the terminal, which are bandwidth part-specific (BWP-specific). The current network side device configures cross-carrier scheduling, wherein a serving cell 1 operating on a CC 1 in a licensed band may schedule a serving cell 2 operating on a CC 2 in an unlicensed band, BWP (i.e. BWP 1) with BWP ID 1 in the serving cell 1 and DRX configuration 1 are associated, a terminal may monitor a PDCCH indicating downlink transmission on BWP1 in the serving cell 1, the PDCCH may schedule a cell 2, the terminal receives a DRX command message on BWP (i.e. BWP2) with BWP ID 2 in the serving cell 2, and BWP2 and DRX configuration 2 in the serving cell 2 are associated, then:

stopping a DRX duration timer in BWP1 associated DRX configuration 1 of serving cell 1 transmitting the PDCCH and stopping a DRX deactivation timer in BWP1 associated DRX configuration 1 in case the terminal receives a DRX command MAC CE or a long DRX command MAC CE on BWP2 on serving cell 2;

under the condition that a terminal receives a DRX command MAC CE on BWP2 on a 2 nd serving cell, if a DRX configuration 1 associated with BWP1 sets a short DRX period, starting or restarting a DRX short period timer in the DRX configuration at the starting time of a first OFDM symbol after the DRX command MAC CE is received, and using the short DRX period; if the short DRX period is not set in the DRX configuration 1 associated with the BWP1, the DRX configuration 1 associated with the BWP1 uses the long DRX period;

in the case that the terminal receives a long DRX command MAC CE on BWP2 on serving cell 2, if a short DRX cycle is set for DRX configuration 1 associated with BWP1, the DRX short cycle timer in the configuration is stopped at the start of the first OFDM symbol after receiving the DRX command MAC CE; if the short DRX period is not set by the DRX configuration 1 associated with BWP1, the DRX configuration 1 associated with BWP1 uses the long DRX period.

It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.

In the embodiment of the invention, when a terminal is configured with cross-carrier scheduling and uses at least two sets of discontinuous reception DRX configurations, a DRX command message sent by a network side device in a scheduled cell is received; applying the DRX command message to a target DRX configuration of the at least two sets of DRX configurations; the target DRX configuration is a DRX configuration which has an association relation with the scheduling cell; the scheduling cell is a serving cell in which the terminal monitors a physical downlink control channel. Therefore, the terminal can be prevented from continuously monitoring the PDCCH on the scheduling cell when no uplink and downlink data are transmitted, and the electric quantity of the terminal is saved.
