In the embodiment of the present invention, different control information, and different schemes for data transmission between the network side device and the terminal device are different, which is specifically described in the following embodiment.

The first embodiment is as follows: the control information is PDCCH scheduling information.

Specifically, the terminal device may be in a real-time monitoring state when monitoring the PDCCH scheduling information on the control channel configured by the network side device, and after monitoring the PDCCH scheduling information, receive data on a corresponding carrier according to the scheduling information of the carrier included in the PDCCH scheduling information; the PDCCH scheduling information can also be monitored at the initial moment of the awakening state, and after the PDCCH scheduling information is monitored, data is received on the corresponding carrier according to the scheduling information of the carrier contained in the PDCCH scheduling information.

The first method is as follows: and the terminal equipment monitors a control value channel configured by the network side equipment in real time.

Optionally, the network side device sends configuration information to the terminal device, where the configuration information includes first bandwidth set information used for indicating a first bandwidth set, and also includes second bandwidth set information used for indicating a second bandwidth set;

specifically, a first bandwidth set in a configuration message sent by the network side device to the terminal device includes N carriers CC1, CC2 \8230, 8230, CCn, and a second bandwidth set includes M carriers CC1, CC2, \8230, 8230, CCm; wherein the carriers in the first set of bandwidths belong to the second set of bandwidths.

Correspondingly, the terminal device receives configuration information sent by the network side device, determines the first bandwidth set and the second bandwidth set according to the configuration information, and listens to a control channel in the first bandwidth set;

specifically, the terminal device determines that a first bandwidth set comprises N carriers CC1 and CC2 \8230 \ 8230, CCn and a second bandwidth set comprises M carriers CC1, CC2, \8230 \ 8230, CCn \8230, 823030and CCm, and monitors control information on control channels corresponding to the N carriers in the first bandwidth set.

Optionally, the network side device sends PDCCH scheduling information to the terminal device on a control channel in the first bandwidth set;

specifically, the network side device sends PDCCH scheduling information on CC1, CC2, 8230, (823030) CCn.

Correspondingly, the terminal device monitors control information on a control channel in the first bandwidth set, and after detecting that PDCCH scheduling information sent by the network side device is PDCCH scheduling information corresponding to the terminal device, the terminal device monitors a data channel in the second bandwidth set and receives data on the data channel in the second bandwidth set.

Specifically, the terminal device detects whether PDCCH scheduling information exists on the CC1, the CC2, the 8230, the CCn in real time, compares the PDCCH scheduling information with the PDCCH scheduling information in the terminal device after detecting that the PDCCH scheduling information exists, and receives PDSCH data on the second bandwidth set according to the information in the PDCCH scheduling information after determining that the PDCCH scheduling information corresponds to the terminal device. And if the PDCCH scheduling information sent by the network side equipment and detected and received by the terminal equipment is not the PDCCH scheduling information corresponding to the terminal equipment, not receiving PDSCH data.

As shown in fig. 2, a schematic diagram of a first terminal device according to an embodiment of the present invention that monitors a control channel and then receives data is shown, where an oblique line filled region indicates a PDCCH On state, which indicates that the monitored PDCCH scheduling information is PDCCH scheduling information corresponding to the terminal device; the network cable filling area represents a PDCCH Off state, and indicates that the monitored PDCCH scheduling information is not the PDCCH scheduling information corresponding to the terminal equipment or does not have the PDCCH scheduling information;

the solid line box represents the PDSCH On state, which indicates that there is data transmission and PDSCH data is received; the dashed box indicates PDSCH Off state, indicating no data transmission and no reception of PDSCH data.

Specifically, the PDCCH scheduling information corresponding to the terminal device is monitored on the control channel corresponding to the carrier CC1 as the PDCCH scheduling information corresponding to the terminal device, and the terminal device performs a monitoring process on the carrier in the second bandwidth set according to the PDCCH scheduling information, monitors whether there is data transmission on the PDSCH, and receives corresponding data if there is data transmission; or

And if the terminal equipment monitors that the PDCCH scheduling information on the control channel corresponding to the carrier CC1 is not the PDCCH scheduling information corresponding to the terminal equipment, the terminal equipment does not monitor the PDSCH.

The PDCCH scheduling information may only include scheduling information of a certain carrier. As shown in fig. 2, if the PDCCH scheduling information on the carrier CC1 only includes the scheduling information of the PDSCH on the CC1, the terminal device only receives PDSCH data on the carrier CC 1. And if the PDCCH scheduling information contains scheduling information of a PDSCH of the CC2, the terminal equipment only receives PDSCH data on the CC 2. The PDCCH scheduling information can also comprise CC1 and CC2 8230, 8230CCn 8230, PDSCH scheduling information of CCm, and PDSCH data is received on the carriers CC1 and CC2 8230, CCn 823082308230, CCm.

The second method comprises the following steps: the terminal device listens to a control channel configured by the network side device at the initial moment of the activation state.

specifically, a first bandwidth set in a configuration message sent by the network side device to the terminal device includes N carriers CC1, CC2 \8230, 8230, CCn, and a second bandwidth set includes M carriers CC1, CC2, \8230, 8230, CCm; wherein carriers in the first set of bandwidths belong to the second set of bandwidths.

specifically, the network side equipment sends PDCCH scheduling information on CC1, CC2 \8230:, CCn.

Specifically, when DRX is in an activated state, the terminal device detects whether PDCCH scheduling information exists on CC1, CC2 \8230 \8230onCCn, and after the PDCCH scheduling information corresponding to the terminal device is detected, the terminal device receives PDSCH data on the second wide set according to the information in the PDCCH scheduling information. And if the terminal equipment detects that the received PDCCH scheduling information sent by the network side equipment is not the PDCCH scheduling information corresponding to the terminal equipment, the terminal equipment does not receive PDSCH data.

As shown in fig. 3, a schematic diagram of a second terminal device provided in the embodiment of the present invention for monitoring a control channel and receiving data, where DRX ON indicates that DRX is in an active state, and DRX Off indicates that DRX is in a sleep state;

the oblique line filling region represents a PDCCH On state, and shows that the monitored PDCCH scheduling information is the PDCCH scheduling information corresponding to the terminal equipment; the network cable filling area represents a PDCCH Off state, and shows that the monitored PDCCH scheduling information is not the PDCCH scheduling information corresponding to the terminal equipment or does not represent the PDCCH scheduling information;

the solid line box represents the PDSCH On state, illustrating reception of PDSCH data; the dashed box indicates PDSCH Off state, indicating that PDSCH data is not received.

Specifically, the PDCCH scheduling information corresponding to the terminal device is monitored on a control channel corresponding to the carrier CC1 as the PDCCH scheduling information corresponding to the terminal device, and the terminal device receives PDSCH data on the carrier in the second bandwidth set according to the PDCCH scheduling information; or

And if the terminal equipment monitors that the PDCCH scheduling information on the control channel corresponding to the carrier CC1 is not the PDCCH scheduling information corresponding to the terminal equipment, the terminal equipment does not receive the PDSCH data.

The PDCCH scheduling information may only include scheduling information of a certain carrier. As shown in fig. 3, if the PDCCH scheduling information on the carrier CC1 only includes the scheduling information of the PDSCH on the CC1, the terminal device only receives PDSCH data on the carrier CC 1. And if the PDCCH scheduling information contains scheduling information of a PDSCH of the CC2, the terminal equipment only receives PDSCH data on the CC 2. The PDCCH scheduling information can also comprise CC1 and CC2 8230, 8230CCn 8230, PDSCH scheduling information of CCm, and PDSCH data is received on the carriers CC1 and CC2 8230, CCn 823082308230, CCm.

In implementation, a terminal device determines a control channel to be monitored according to a first bandwidth set in configuration information sent by a network side device, monitors the control information sent by the network side device on the control channel, detects that the control information sent by the network side device is PDCCH scheduling information, and determines that the PDCCH scheduling information is PDCCH scheduling information corresponding to the terminal device, and then determines to receive data on a PDSCH in a second bandwidth set determined according to the configuration information according to information included in the PDCCH scheduling information.

Example two: when the control information is a wake-up signal.

The Wake-up signal is a WUS (Wake-up signal) and is used for indicating whether PDCCH scheduling information exists in DRX on time to the terminal equipment.

Specifically, after the terminal device detects the corresponding wake-up signal, the terminal device may listen to a control channel in the first bandwidth set or a control channel in the second bandwidth set, and then receive data on a data channel in the second bandwidth set.

The method I comprises the following steps: and after detecting that the control information is the wake-up signal corresponding to the terminal device, the terminal device monitors the control channel in the second bandwidth set, and then judges whether data needs to be received on the second bandwidth set according to the control channel information in the second bandwidth set.

Correspondingly, the terminal device receives the configuration information sent by the network side device, determines a first bandwidth set and a second bandwidth set in the configuration information, listens to a control channel in the first bandwidth set, and detects whether there is control information corresponding to the terminal device.

Optionally, the network side device sends a wake-up signal to the terminal device in the first bandwidth set;

specifically, the network side device sends a wake-up signal on CC1, CC2 \8230:, CCn.

Correspondingly, the terminal device listens to the control information of the control channel in the first bandwidth set, and if the wake-up signal sent by the network side device is detected to be the wake-up signal corresponding to the terminal device, the terminal device listens to the control channel in the second bandwidth set and receives PDSCH data on the data channel in the second bandwidth set according to the control channel information in the second bandwidth set.

Specifically, before the DRX is in an active state, the terminal device monitors whether a wake-up signal is present on the CC1, the CC2, the 8230, the CCn, and after the wake-up signal is detected, the terminal device determines whether the wake-up signal is a wake-up signal corresponding to the terminal device, and after determining that the received wake-up signal sent by the network-side device is a wake-up signal corresponding to the terminal device, the terminal device detects PDCCH scheduling information in control channels corresponding to all carriers in the second bandwidth set after the DRX is in the active state, and receives PDSCH data in a data channel corresponding to the carriers in the second bandwidth set according to the PDCCH scheduling information after detecting the PDCCH scheduling information.

And if the terminal equipment detects the PDCCH scheduling information in all the carriers in the second bandwidth set and if the PDCCH scheduling information is detected on part of the carriers in the second bandwidth set, the terminal equipment receives PDSCH data on the second bandwidth set according to the detected PDCCH scheduling information.

As shown in fig. 4, a schematic diagram of a third terminal device provided in the embodiment of the present invention to listen to a control channel and then receive data is shown. Wherein DRX ON represents that DRX is in an active state, and DRX Off represents that DRX is in a sleep state;

a horizontal line filling area indicates that a WUS state corresponding to the terminal device exists, and a vertical line filling area indicates that the WUS state corresponding to the terminal device does not exist;

the diagonal filling area represents a PDCCH On state, which indicates that the detected PDCCH scheduling information is the PDCCH scheduling information corresponding to the terminal equipment, and the diagonal filling area represents a PDCCH Off state, which indicates that the detected PDCCH scheduling information is not the PDCCH scheduling information corresponding to the terminal equipment or does not have the PDCCH scheduling information;

the solid line box represents PDSCH On state, which represents receiving PDSCH data; the dashed box indicates PDSCH Off state, indicating that PDSCH data is not received.

If the terminal device detects a wake-up signal corresponding to the terminal device on a control channel on the carrier CC1, the control channel may be a WUS resource time-frequency domain position notified by an RRC signaling. And the terminal equipment detects PDCCH scheduling information on the control channels corresponding to all the carriers in the second bandwidth set, and continues to receive PDSCH data after the PDCCH scheduling information is detected.

As shown in fig. 4, when detecting that the terminal device corresponds to the wake-up signal in the control region corresponding to the carrier CC1, PDCCH scheduling information indicated in the wake-up signal is detected at DRX On time of all carriers CC1, CC2, 8230, CCn, 8230, and CCm in the second bandwidth set, and PDSCH data is received after the PDCCH scheduling information is detected.

In implementation, a terminal device determines a control region to be monitored according to a first bandwidth set in configuration information sent by a network side device, monitors the control information sent by the network side device in the control region, monitors that the control information is a wake-up signal, determines that the wake-up signal is a wake-up signal corresponding to the terminal device, determines that PDCCH scheduling information exists in the wake-up signal, detects PDCCH scheduling information on all carriers in a second bandwidth set determined according to the configuration information, and receives PDSCH data on all carriers in the second bandwidth set after detecting the corresponding scheduling information.

The second method comprises the following steps: and after detecting that the control information is the wake-up signal corresponding to the terminal equipment, the terminal equipment receives PDSCH data on the second bandwidth set according to the control information by monitoring the control information of the control channel in the first bandwidth set.

specifically, a first bandwidth set in a configuration message sent by the network side device to the terminal device includes N carriers CC1, CC2 \8230, a second bandwidth set includes M carriers CC1, CC2, \8230, a third bandwidth set includes M carriers 8230, a third bandwidth set includes M carriers CC1, CC2, \8230, a fourth bandwidth set includes M carriers 8230, a fourth bandwidth set includes M carriers CCn \8230, and a third bandwidth set includes M carriers CCm; wherein carriers in the first set of bandwidths belong to the second set of bandwidths.

Correspondingly, the terminal device receives configuration information sent by the network side device, determines a first bandwidth set and a second bandwidth set according to the configuration information, and monitors control information on a control channel in the first bandwidth set;

Optionally, the network side device sends a wake-up signal to the terminal device in the control area in the first bandwidth set;

Correspondingly, the terminal device listens to the control information on the control channel in the first bandwidth set, listens to the control channel in the first bandwidth set after detecting that the wake-up signal sent by the network side device is the wake-up signal corresponding to the terminal device, and receives data on the data channel in the second bandwidth set according to the control channel information in the first bandwidth set.

Specifically, before DRX is in an active state, the terminal device monitors whether an wake-up signal exists on carriers CC1, CC2 \8230, 8230, and CCn, and after the wake-up signal is monitored, the terminal device judges whether the wake-up signal is a wake-up signal corresponding to the terminal device, and after the received wake-up signal sent by the network side device is determined to be the wake-up signal corresponding to the terminal device, the terminal device detects PDCCH scheduling information in control channels corresponding to all carriers (CC 1, CC2 \8230; 8230and CCn) in the first bandwidth set when DRX is in the active state, and receives PDSCH data on data channels corresponding to all carriers in the second bandwidth set according to information indicated in the PDCCH scheduling information after the PDCCH scheduling information is detected.

For example, the PDCCH scheduling information includes PDSCH scheduling information of the carrier CCn and the carrier CCm, and the terminal device receives PDSCH data on the PDSCH of the carrier CCn and the carrier CCm.

Fig. 5 is a schematic diagram of a fourth terminal device listening to a control channel and receiving data according to an embodiment of the present invention, where the meaning of each part in fig. 5 is shown in fig. 4.

Specifically, the terminal device detects a wake-up signal corresponding to the terminal device in a control region corresponding to a carrier CC1 before DRX On, and then detects PDCCH scheduling information at DRX On time of the carrier CC1, CC2, 8230, and CCn in a first bandwidth set, and receives PDSCH data On a PDSCH corresponding to a carrier in a second bandwidth set according to PDSCH scheduling information contained in the PDCCH scheduling information.

It should be noted that, when detecting the wake-up signal, the terminal device performs detection in a control region corresponding to a control channel configured for the terminal device by the network side device, where the control region is before the control channel.

In implementation, the terminal device determines a control region to be monitored according to a first bandwidth set in configuration information sent by a network side device, monitors a wake-up signal sent by the network side device in the control region, and detects PDCCH scheduling information on a carrier in the first bandwidth set when DRX is in an active state after determining that the wake-up signal is a wake-up signal corresponding to the terminal device, and further receives PDSCH data on a carrier in the second bandwidth set according to PDSCH scheduling information of the carrier included in the PDCCH scheduling information.

Example three: the control information is the control information scrambled by the DRX-RNTI.

The control information scrambled by the DRX-RNTI is a specific RNTI (Radio Network Temporary Identifier), and the DRX-RNTI is used for indicating whether PDCCH scheduling information of the terminal device exists in a DRX active state in a DRX cycle.

Specifically, if the terminal device detects the corresponding DRX-RNTI scrambled control information within the DRX activated start time unit, the terminal device may listen to the control channel in the first bandwidth set or the control channel in the second bandwidth set, and then receive the PDSCH data on the data channel in the second bandwidth set.

The first method is as follows: and the terminal equipment detects that the control information is scrambled control information of DRX-RNTI corresponding to the terminal equipment, monitors a control channel in the second bandwidth set and then receives PDSCH data in the second bandwidth set.

Correspondingly, after receiving the configuration information sent by the network side device, the terminal device determines a first bandwidth set and a second bandwidth set in the configuration information, listens to a control channel in the first bandwidth set, and detects whether there is control information corresponding to the terminal device.

Specifically, the terminal device determines that a first bandwidth set comprises N carriers CC1, CC2 \8230, carriers 8230, carriers CCn, and a second bandwidth set comprises M carriers CC1, CC2, \8230, carriers 8230, carriers CCn \8230, carriers 8230, and control information is intercepted on control channels corresponding to the N carriers in the first bandwidth set.

Optionally, the network side device sends the control information scrambled by the DRX-RNTI to the terminal device on the control channel in the first bandwidth set.

Specifically, the network side equipment sends DRX-RNTI scrambled control information on CC1, CC2 \8230; CCn.

The control information scrambled by the RX-RNTI is sent by the network side device in a signaling manner, such as RRC signaling.

Correspondingly, the terminal device monitors the control information of the control channel in the first bandwidth set, monitors the control channel in the second bandwidth set after detecting that the control information scrambled by the DRX-RNTI sent by the network side device is the control information scrambled by the DRX-RNTI corresponding to the terminal device, and receives data on the data channel of the second bandwidth set according to the control channel information in the second bandwidth set.

Specifically, the terminal device monitors whether control information scrambled by DRX-RNTI exists on CC1, CC2 \8230, 8230, CCn at the starting time when DRX is in an activated state, monitors the control information scrambled by DRX-RNTI, determines that the control information scrambled by DRX-RNTI is the control information scrambled by DRX-RNTI corresponding to the terminal device, and receives data on a data channel PDSCH corresponding to all carriers in a second bandwidth set according to PDCCH scheduling information contained in the control information scrambled by DRX-RNTI.

If the terminal equipment monitors DRX-RNTI scrambled control information on the CC1, the CC2, the 8230, the CCn and the DRX-RNTI scrambled control information is not the DRX-RNTI scrambled control information corresponding to the terminal equipment, the terminal equipment directly enters a sleep state and does not monitor PDCCH on all carriers in a second bandwidth set; or

If the terminal equipment does not detect the control information scrambled by the DRX-RNTI on the CC1, the CC2, the 8230, and the CCn, the terminal equipment directly enters a sleep state and does not detect the control channels PDCCH on all the carriers in the second bandwidth set.

As shown in fig. 6, a schematic diagram of a fifth terminal device provided in the embodiment of the present invention to listen to a control channel and then receive data is shown. Wherein DRX ON represents that DRX is in an active state, and DRX Off represents that DRX is in a sleep state;

a horizontal line filling area represents an RNTI On state, the control information scrambled by the DRX-RNTI is the control information scrambled by the DRX-RNTI corresponding to the terminal equipment, and PDCCH dispatching information is contained in the control information scrambled by the DRX-RNTI; the vertical line filling area represents an RNTI Off state, and shows that the control information scrambled by the DRX-RNTI is not the control information scrambled by the DRX-RNTI corresponding to the terminal equipment and/or the control information scrambled by the DRX-RNTI does not have PDCCH scheduling information;

the solid line box represents the PDSCH On state, indicating reception of PDSCH data; the dashed box indicates PDSCH Off state, indicating that PDSCH data is not received.

Specifically, the terminal device receives control information scrambled by a DRX-RNTI corresponding to the terminal device on a control channel corresponding to a carrier CC1, and the control information scrambled by the DRX-RNTI has PDCCH scheduling information, the terminal device detects that the control information scrambled by the DRX-RNTI has PDCCH scheduling information on a carrier of a second bandwidth set, and receives data on a PDSCH of a data channel on the carrier of the second bandwidth set according to PDSCH scheduling information of the carrier included in the PDCCH scheduling information.

In implementation, the terminal device determines a first bandwidth set according to configuration information of a network side device, monitors control information on a control channel corresponding to a carrier in the first bandwidth set, determines that the monitored control information is control information scrambled by a DRX-RNTI corresponding to the terminal device, determines PDCCH scheduling information in the control information scrambled by the DRX-RNTI on the carrier in the second bandwidth set, and receives data on a data channel PDSCH according to PDSCH scheduling information of the carrier included in the PDCCH scheduling information; because the control channel intercepted by the terminal equipment is configured by the network side equipment, the control channel at all positions does not need to be intercepted when the control channel is intercepted, and the electric quantity is saved.

The second method comprises the following steps: and the terminal equipment detects that the control information is control information scrambled by DRX-RNTI corresponding to the terminal equipment, monitors a control channel in the first bandwidth set and receives PDSCH data in the second bandwidth set according to the control information of the control channel.

Correspondingly, the terminal device receives configuration information sent by the network side device, determines a first bandwidth set and a second bandwidth set according to the configuration information, and monitors control information in a control channel in the first bandwidth set;

Optionally, the network side device sends control information scrambled by DRX-RNTI to the terminal device on a control channel in the first bandwidth set;

specifically, the network side equipment sends DRX-RNTI scrambled control information on CC1, CC2 \8230; \8230ccn.

Correspondingly, the terminal device listens to control information of a control channel in the first bandwidth set, listens to the control channel in the first bandwidth set after detecting that the control information scrambled by the DRX-RNTI sent by the network side device is the control information scrambled by the DRX-RNTI corresponding to the terminal device, listens to a data channel in the second bandwidth set according to the control channel information in the first bandwidth set, and receives data through the data channel in the second bandwidth set.

Specifically, the terminal device monitors whether control information scrambled by DRX-RNTI exists on CC1, CC2 \8230 \ 8230;, and CCn, monitors the control information scrambled by DRX-RNTI, determines that the control information scrambled by DRX-RNTI is the control information scrambled by DRX-RNTI corresponding to the terminal device, detects PDCCH scheduling information contained in the control information scrambled by DRX-RNTI corresponding to a carrier in the first bandwidth set, and receives data in a data channel corresponding to the carrier in the second bandwidth set according to information indicated in the PDCCH scheduling information.

If the terminal equipment monitors DRX-RNTI scrambled control information on the CC1, the CC2, the 8230, the CCn and the DRX-RNTI scrambled control information is not DRX-RNTI scrambled control information corresponding to the terminal equipment, the terminal equipment directly enters a sleep state and does not monitor PDCCH on all carriers in a second bandwidth set; or

If the terminal equipment does not listen to control information scrambled by DRX-RNTI on CC1, CC2, 8230velocity, 8230CCn, the terminal equipment directly enters a sleep state.

As shown in fig. 7, a schematic diagram of a sixth terminal device provided in the embodiment of the present invention that listens to a control channel and then receives data is shown; the meaning of each part in fig. 7 is shown in fig. 6.

Specifically, at the starting time of the terminal device DRX On, receiving control information scrambled by DRX-RNTI corresponding to the terminal device On a control channel corresponding to a carrier CC1, detecting that PDCCH scheduling information exists in the control information scrambled by the DRX-RNTI On a carrier CC1, a carrier CC2, 8230, CCn, and receiving PDSCH data On a data channel corresponding to the carrier in a second bandwidth set according to PDSCH scheduling information contained in the PDCCH scheduling information.
