In 5G NR, the network device may configure DRX functionality for the terminal device, so that the terminal device discontinuously listens to the physical downlink control channel (Physical Downlink Control Channel, PDCCH) to achieve the purpose of terminal power saving. Each MAC entity has a DRX configuration, and the configuration parameters of the DRX include:

DRX activation timer (DRX-onduration timer): the duration of the UE waking up at the beginning of one DRX Cycle (Cycle), as shown in fig. 2;

DRX slot offset (DRX-SlotOffset): the UE starts the time delay of the drx-ondurationTimer;

DRX inactivity timer (DRX-inactivity timer): after receiving a PDCCH indicating uplink primary transmission or downlink primary transmission, the UE continues to monitor the duration of the PDCCH;

DRX DownLink (DL) retransmission timer (DRX-retransmission timer DL): the UE listens for the longest duration of the PDCCH indicating the downlink retransmission schedule. Each downlink hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) process except for the broadcast HARQ process corresponds to one drx-retransmission timerdl;

DRX UpLink (UL) retransmission timer (DRX-retransmission timer UL): the UE monitors the longest duration of PDCCH indicating uplink retransmission scheduling, and each uplink HARQ process corresponds to one drx-retransmission TimerUL;

DRX long cycle start offset (DRX-longcycletartoffset): for configuring a Long DRX cycle (Long DRX cycle), and subframe offsets at which the Long DRX cycle and Short DRX cycle (Short DRX cycle) start;

DRX short cycle (DRX-short): short DRX cycle, is optional configuration;

DRX short cycle timer (DRX-ShortCycleTimer): the duration that the UE is in Short DRX cycle (and does not receive any PDCCH) is an optional configuration;

DRX downlink hybrid automatic repeat request Round Trip Time (RTT) timer (DRX-HARQ-RTT-TimerDL): the UE expects to receive the minimum waiting time required by the PDCCH indicating downlink scheduling, and each downlink HARQ process except the broadcast HARQ process corresponds to one drx-HARQ-RTT-TimerDL;

DRX uplink hybrid automatic repeat request round trip transmission time (DRX-HARQ-RTT-timertul): the UE expects to receive the minimum latency required to indicate the uplink scheduled PDCCH, one drx-HARQ-RTT-timer ul for each uplink HARQ process.

If the terminal configures DRX, the terminal needs to monitor PDCCH at DRXACtive Time. The DRX Active Time includes the following cases:

any one of 5 timers, drx-onduration timer, drx-incarvitytimer, drx-retransmission timer dl, drx-retransmission timer ul, and ra-contentducingtime is running;

the SR is transmitted on the PUCCH and is in a waiting (pending) state;

in the contention-based random access procedure, the terminal device has not received one initial transmission of the cell radio network temporary identity (Cell Radio Network Temporary Identifier, C-RNTI) scrambled PDCCH indication after successful reception of the random access response.

The terminal device decides the time for starting the DRX-onduration timer according to whether the terminal device is currently in the short DRX cycle or the long DRX cycle, and specifically specifies the following steps:

if Short DRX Cycle is used and the current subframe satisfies [ (sfn×10) +subframe number ] module (DRX-Short Cycle) = (DRX-StartOffset) module (DRX-Short Cycle) or if Long DRX Cycle is used and the current subframe satisfies [ (sfn×10) +subframe number ] module (DRX-LongCycle) = DRX-StartOffset;

The drx-onduration timer is started at a time after the drx-SlotOffset slot at the beginning of the current subframe.

In order to provide a larger data transmission rate and improve user experience, the 5G NR further increases the system bandwidth on a 4G basis. In 5G NR, for frequency bands below 6GHz, the maximum bandwidth supported by single carrier is 100MHz; for the frequency band above 6GHz, the maximum bandwidth supported by a single carrier is 400MHz.

Like the LTE system, 5G NR also supports CA technology. For a terminal device supporting CA characteristics, the terminal device may have one Primary Cell (PCell), and the network RRC may configure one or more Secondary cells (scells) for the terminal. SCell has both active and inactive states. Only when the SCell is in an active state, the terminal device may transmit and receive data on this SCell. The terminal device may monitor the PDCCH on the PCell and the activated one or more scells at the same time, and transmit and receive data, thereby improving the data transmission rate.

And the terminal equipment applies for uplink resources to the network equipment through the SR. The network device does not know when the terminal needs to transmit uplink data, i.e. when the terminal will transmit SRs. Therefore, the network device may allocate a periodic PUCCH resource for transmitting SR to the terminal device, and then the network device detects whether there is SR reporting on the already allocated SR resource.

As can be seen from the above triggering conditions for SRs, the SRs in the NR are based on logical channels. For each uplink logical channel, the network device may select whether PUCCH resources for transmitting SRs are configured for the uplink logical channel. If the network equipment configures PUCCH resources for transmitting the SR for the uplink logic channel under the condition that the uplink logic channel triggers the SR, the terminal equipment transmits the SR on the PUCCH resources for transmitting the SR corresponding to the logic channel; otherwise, the terminal initiates random access.

The network device may configure the terminal device with a plurality of PUCCH resources for transmitting SRs. For an uplink logical channel, if the network device configures PUCCH resources for transmitting SRs for the uplink logical channel, the network device configures at most one PUCCH resource for transmitting SRs for the logical channel on each uplink Bandwidth Part (BWP) of each serving cell of the terminal device.

Each PUCCH resource for transmitting an SR corresponds to the following configuration parameters:

PUCCH resource period and slot/time symbol offset;

PUCCH resource index.

In the NR CA scenario, a DRX enhancement method is proposed, i.e. a scheme in which 2 DRX groups can be configured for one MAC entity. For this DRX enhancement method, the following explicit conclusions have been made at present:

For DRX group2, the network device may configure it with one DRX-incavitytimer and DRX-onduration timer. Namely, the network device configures a DRX-InactivityTimer and a DRX-ondurationTimer for 2 DRX groups respectively, and the rest DRX configuration parameters are common configuration parameters of 2 DRX groups;

cross-carrier scheduling between 2 DRX groups is not supported.

Under the current mechanism that one MAC entity corresponds to one DRX configuration, if the UE sends an SR on the PUCCH, the UE enters into the DRX Active Time. For the above-mentioned DRX enhancement method, in the case of configuring 2 DRX groups for one MAC entity, if a certain uplink logical channel of the UE has data arrival triggering SR, the UE sends the SR on the PUCCH of one serving cell, where the UE enters DRX Active Time on 1 DRX group of the 2 DRX groups corresponding to the MAC entity or enters DRX Active Time on 2 DRX groups at the same Time, and if the UE enters DRX Active Time on 1 DRX group, the UE should enter DRX Active Time on which DRX Active group. These problems above need to be solved from the standard level.

Accordingly, the embodiment of the application provides a method for determining an activation period.

Fig. 3 is a schematic flow chart of a first method 100 of determining an activation period provided in accordance with an embodiment of the present application. The method 100 may be performed by a user equipment, which may be, for example, a terminal device as shown in fig. 1.

As shown in fig. 3, the method 100 includes:

step S302, an uplink logic channel of the user equipment triggers the user equipment to send a scheduling request SR on a physical uplink control channel PUCCH, wherein a MAC entity of the user equipment is configured with a plurality of discontinuous reception groups;

the method provided by the embodiment of the application is applied to the CA scene, and aiming at the situation that one MAC entity configures a plurality of DRX groups, the network equipment can configure a plurality of DRX groups for the UE, so that the UE discontinuously monitors the PDCCH, and the purpose of terminal power saving is achieved.

The SR-based triggering condition is that the SR is based on a logical channel, and the uplink logical channel of the UE has data arriving, that is, if one uplink logical channel of the UE receives triggering data for triggering the sending of the scheduling request, the UE is triggered to send the scheduling request on a physical uplink control channel of an uplink BWP of a serving cell. And, this uplink control channel is an SR configured to the UE for transmitting the logical channel trigger.

Step S304, the user equipment obtains at least one discontinuous receiving group corresponding to the transmission limit information of the uplink logic channel;

in this embodiment, the transmission restriction information is used to determine a serving cell that allows the uplink logical channel to perform data transmission, and may include: the set of serving cells that allow data transmission by the uplink logical channel and/or the set of subcarrier spacings that allow data transmission by the uplink logical channel are not limited thereto, but may include other limiting parameters. In the present application, two limiting parameters of a serving cell set and/or a subcarrier spacing set are taken as examples for illustration, and other implementation schemes of the limiting parameters are similar and are not described herein. The network device may configure, for an uplink logical channel, a serving cell allowedServingCells and/or subcarrier spacing sets that allow transmission of the uplink logical channel, where the configured allowedServingCells include DRX groups corresponding to the serving cell, and the configured subcarrier spacing sets also include DRX groups corresponding to the serving cell.

For a set of serving cells, the serving cell may be determined based on the ID of the serving cell; for the set of subcarrier spacings, the serving cell may be determined based on the subcarrier spacing corresponding to the serving cell subcarrier.

In this embodiment, the ue may acquire the configuration information of the uplink logical channel before the ue acquires at least one discontinuous reception group corresponding to the transmission restriction information of the uplink logical channel.

Wherein, the configuration information at least comprises: uplink control channel resources for transmitting an SR triggered by an uplink logical channel and transmission restriction information of the uplink logical channel.

For each uplink logical channel of the UE, the network device may select whether PUCCH resources for transmitting SRs are configured for the uplink logical channel. If the network configures a PUCCH resource for transmitting SR for an uplink logical channel under the condition that the SR is triggered by the uplink logical channel, the terminal sends the SR on the PUCCH resource for transmitting SR corresponding to the logical channel, and determines according to the configuration information.

It should be noted that, because the UE may have configured multiple uplink logical channels at the same time, and the configuration information of each uplink logical channel is different, after a certain uplink logical channel of the UE receives the trigger data, the configuration information of the uplink logical channel may be obtained.

In step S306, the ue enters an active period of discontinuous reception on at least one discontinuous reception group according to the transmission restriction information of the uplink logical channel.

In this embodiment, if the network device configures allowedServingCells for the uplink logical channel, the UE may enter DRX Active Time in the corresponding DRX group based on the DRX group corresponding to the serving cell included in the allowedServingCells. Thereafter, the UE listens to the PDCCH on the (active) serving cell corresponding to the DRX group.

Based on the scheme provided by the embodiment of the application, under the condition that a plurality of discontinuous reception groups are configured for the MAC entity of the user equipment, after the uplink logic channel triggers the user equipment to send the scheduling request SR on the physical uplink control channel PUCCH, the user equipment can enter the activation period of discontinuous reception on at least one discontinuous reception group according to the transmission limit information of the uplink logic channel, thereby realizing that the user equipment is triggered to enter the activation period of discontinuous reception on at least one discontinuous reception group through the SR, not only ensuring the scheduling performance, but also taking into account the power saving of the terminal.

In the above embodiment of the present application, the ue may receive network configuration information and configure the ue, where the network configuration information at least includes: parameters of each discontinuous receiving group configured for the MAC entity of the user equipment, configuration parameters of a plurality of service cells, association relation between the service cells and the discontinuous receiving groups, configuration information of uplink logic channels, whether uplink control channel resources and transmission limit information are configured on each uplink logic channel of the user equipment.

In this embodiment, the UE receives network radio resource control (Radio Resource Control, RRC) configuration information, configures DRX related parameters, SCell related parameters, uplink logical channel related configuration, SR related configuration, and specifically includes the following steps:

the DRX related parameter configuration includes: and configuring a plurality of DRX groups for one MAC entity of the UE, wherein the DRX groups correspond to different DRX-InactyTimer and/or DRX-ondurationTimer configurations.

The SCell configuration parameter includes at least one SCell.

And each SCell corresponds to one of the configured DRX groups, and the PCell corresponds to the DRX group1 by default.

If the network device selects to configure PUCCH resources for transmitting SRs for the uplink logical channel, the network device may configure 0 or 1 PUCCH resources for transmitting SRs on each UL BWP of each serving cell of the UE for the uplink logical channel. Optionally, the user equipment obtaining configuration information of the uplink logical channel includes: and configuring uplink control channel resources on the bandwidth part BWP of the service cell corresponding to the uplink logical channel.

For each uplink logic channel configured with PUCCH resources for transmitting SR, the network device configures a serving cell list allowed to transmit the uplink logic channel for the uplink logic channel at the same time, where the serving cell list allowed to transmit the uplink logic channel is optionally configured.

Optionally, the user equipment periodically starts a DRX activation timer for each discontinuous reception group, respectively, based on the network configuration information. In this embodiment, for a plurality of DRX groups, DRX-onduration timer is periodically started (DRX is timing active during timer running), and the DRX-onduration timer length corresponding to each DRX group is a value configured by the network for the DRX group.

In the above embodiment of the present application, in the case that the transmission restriction information is a set of serving cells that allow uplink logical channels to perform data transmission and/or a set of subcarrier intervals that allow uplink logical channels to perform data transmission, after the ue acquires the configuration information of the uplink logical channels, the method further includes: judging whether an uplink logic channel is configured with a service cell set and/or a subcarrier spacing set; if a service cell set is configured, acquiring a corresponding relation between each service cell in the service cell set and any one or more discontinuous receiving groups configured by user equipment; if the subcarrier interval set is configured, acquiring a corresponding relation between each subcarrier interval in the subcarrier interval set and any one or more discontinuous receiving groups configured by the user equipment; and if the service cell set and the subcarrier interval set are configured, acquiring the corresponding relation between the service cell with the intersection relation in the service cell set and the subcarrier interval set and any one or more discontinuous receiving groups configured by the user equipment.

Optionally, if the network device configures only the serving cell set, the corresponding relationship between the serving cell and the DRX group may be directly obtained, and the user device enters the DRX Active Time on the DRX group corresponding to the serving cell.

If the network device only configures the subcarrier spacing set, the corresponding relationship between the subcarrier spacing and the DRX group can be directly obtained, and the user device enters the DRXACtive Time on the DRX group corresponding to the subcarrier spacing.

If the network device skin configures the service cell set and the subcarrier spacing set, firstly, the service cell with the intersection relationship in the service cell set and the subcarrier spacing set can be determined, namely, the service cell which simultaneously meets the two limiting parameters is determined, then the corresponding relationship of the service cell is obtained, and further the user device enters the DRX Active Time on the DRX group corresponding to the service cell.

In this embodiment, after the UE sends the SR on one PUCCH resource corresponding to the uplink logical channel, the UE may determine according to the configuration of the network device:

in a first alternative embodiment, if all the serving cells in the set of serving cells and/or all the subcarrier spacings in the set of subcarrier spacings correspond to a first discontinuous reception set for the user equipment, the user equipment enters an active period of discontinuous reception on the first discontinuous reception set, wherein the first discontinuous reception set is any one of a plurality of discontinuous reception sets. In this embodiment, the network device configures N DRX groups for the UE, and all serving cells and/or all subcarrier spacings correspond to the same DRX group.

For example, in the case where 2 DRX groups are configured for one MAC entity and only allowedServingCells are configured, as shown in fig. 4a, if all the serving cells included in the allowedServingCells correspond to DRX group1, the UE enters a DRX active Time at DRX group 1. Thereafter, the UE listens to the PDCCH on the (active) serving cell corresponding to DRX group 1. As shown in fig. 4b, if the serving cells included in the allowedServingCells all correspond to DRX group2, the UE enters DRX Active Time at DRX group 2. Thereafter, the UE listens to the PDCCH on the (active) serving cell corresponding to DRX group 2.

In a second alternative embodiment, if the set of serving cells includes serving cells corresponding to the partial discontinuous reception groups, respectively, and/or if the set of subcarrier intervals includes subcarrier intervals corresponding to the partial discontinuous reception groups, respectively, the user equipment enters an active period of discontinuous reception on the partial discontinuous reception groups. In this embodiment, the network device configures N DRX groups for the UE, and all serving cells and/or all subcarrier spacings correspond to only a portion of the DRX groups.

For example, 4 DRX groups are configured for the UE for the network device, respectively: in the case of DRX group1, DRX group2, DRX group3, and DRX group4, only allowedServingCells are configured, and if the allowedServingCells include a serving cell corresponding to DRX group1 and a serving cell corresponding to DRX group3, the UE enters DRX Active Time in DRX group1 and DRX group 3. Thereafter, the UE listens to the PDCCH on the (active) serving cell corresponding to DRX group1 and DRX group 3.

In a third alternative embodiment, if the set of serving cells includes serving cells corresponding to each discontinuous reception group, and/or if the set of subcarrier intervals includes subcarrier intervals corresponding to each discontinuous reception group, the ue enters an active period of discontinuous reception on all configured discontinuous reception groups. In this embodiment, the network device configures N DRX groups for the UE, and all serving cells and/or all subcarrier spacings correspond to the N DRX groups, respectively.

For example, as shown in fig. 4c, in the case that 2 DRX groups are configured for one MAC entity and only allowedServingCells are configured, if the allowedServingCells include both a serving cell corresponding to DRX group1 and a serving cell corresponding to DRX group2, the UE enters DRX Active Time at both DRX group1 and DRX group 2. Thereafter, the UE listens to the PDCCH on all (active) serving cells.

In a fourth alternative embodiment, if the set of serving cells and/or the set of subcarrier spacings are not configured, the user equipment enters an active period of discontinuous reception on all discontinuous reception groups configured. In this embodiment, the network device configures N DRX groups for the UE, and the network device does not configure allowedServingCells and/or subcarrier spacing sets.

For example, as shown in fig. 4d, in the case that 2 DRX groups are configured for one MAC entity and only allowedServingCells are configured, if the network device does not configure allowedServingCells for the uplink logical channel, the UE enters DRX Active Time in both DRX group1 and DRX group 2. Thereafter, the UE listens to the PDCCH on all (active) serving cells.

In the present application, two limiting parameters of a serving cell set and/or a subcarrier spacing set are taken as examples for illustration, and other implementation schemes of the limiting parameters are similar and are not described herein. The network device may configure, for an uplink logical channel, a serving cell allowedServingCells and/or subcarrier spacing sets that allow transmission of the uplink logical channel, where the configured allowedServingCells include DRX groups corresponding to the serving cells, and the configured subcarrier spacing sets also include DRX groups corresponding to the serving cells.

In step S506, the ue enters an active period of discontinuous reception on at least one discontinuous reception group according to the transmission restriction information of the uplink logical channel.
