An embodiment of the present disclosure provides a method for transmitting a downlink channel, and fig. 2 is a flowchart illustrating a method for transmitting a downlink channel according to an exemplary embodiment, and as shown in fig. 2, the method includes steps S201 to S203:

s201, the network equipment sends indication information to the user equipment, wherein the indication information is used for indicating that the reference signal is closed and the closing period corresponding to the reference signal.

In some possible implementations, the network device sends configuration information (which may be sent by radio link control, RRC, signaling) to the user device, the configuration information being used to configure at least one spatial cell group, which is a candidate spatial cell group that may be turned off, each spatial cell group including one or more Reference signals. The space unit group comprises a plurality of space units, and the space units are at least one of the following: antenna elements, ports, TRX chains, beams, panels.

After receiving the indication information, the ue can know which reference signals are turned off and the corresponding turn-off period.

S202, the network equipment sends downlink channel configuration information to the user equipment, wherein the downlink channel configuration information is used for configuring a second period, and the second period is a period when the network equipment sends a downlink channel.

In some possible implementations, when the downlink channel is a physical downlink control channel (physical downlink control channel, PDCCH), the downlink channel configuration information is search space and CORESET configuration information.

In some possible embodiments, when the downlink channel is a semi-persistent scheduling (semi-persistent scheduling, SPS) physical downlink shared channel (physical downlink shared channel, PDSCH), the downlink channel configuration information is SPS PDSCH configuration information. Wherein, the SPS PDSCH is a PDSCH of semi-persistent transmission, is configured with periodic PDSCH transmission resources by higher layers, and is activated and deactivated using downlink control information (Downlink Control Information, DCI).

The execution order of S201 and S202 is not limited to the method of executing S201 first and then S202, and may be the method of executing S202 first and then S201, or may be the method of executing S201 simultaneously.

S203, in response to the off period including a first period, the first period being all or part of a second period, the network device determining whether to transmit the downlink channel in the first period, and the user device determining whether to transmit the downlink channel in the first period.

When the network device determines that the downlink channel is not transmitted in the first period, the network device maintains the original off period unchanged. When the network device determines to transmit the downlink channel in the first period, the network device starts the corresponding reference signal before transmitting the downlink channel, i.e. ends the off period of the corresponding reference signal in advance.

In some possible implementations, when determining whether to transmit the downlink channel in the first period, the network device determines whether to transmit the downlink channel in the first period according to the downlink channel and the reference signal. Correspondingly, when the user equipment determines whether to receive the downlink channel in the first period, determining whether to receive the downlink channel in the first period according to the downlink channel and the reference signal.

In view of the PDCCH for UE specific (specific), the network device may indicate the TCI state of each CORESET using the MAC CE for that CORESET, and in the case of SPS PDSCH, the network device may indicate the TCI state in the activate DCI. The TCI state includes at most 2 reference signals, and the network device configures a PDCCH channel, and QCL relations between the SPS PDSCH and the 2 reference signals are configured respectively, and may be configured into a QCL type (type) A, QCL type (type) B, QCL type (type) C, QCL type (type) D, and so on. If configured as QCL type D, it means that the transmission beam of PDCCH, SPS PDSCH is identical to the reference signal.

In one example of the implementation of the method,

in response to the downlink channel being a physical downlink control channel, PDCCH, and the reference signal being configured as QCL type D in a TCI state of a CORESET associated with the PDCCH, the network device determines not to transmit the PDCCH for the first period of time, and the user device determines not to receive the PDCCH for the first period of time.

In the other of the examples described above, in the present example,

in response to the downlink channel being a semi-statically configured physical downlink shared channel, SPS, PDSCH, and the reference signal being configured as QCL type D in a TCI state of the SPS PDSCH, the network device determines not to transmit the SPS PDSCH for the first period of time, and the user device determines not to receive the SPS PDSCH for the first period of time.

In the above two examples, the downlink channel is not transmitted in the first period of time, and the downlink channel is matched with the dynamic behavior of the network device for closing the reference signal, so that the dynamic behavior of the network device for opening or closing the reference signal has a higher priority than the priority for transmitting the downlink channel, and the dynamic behavior of the network device for opening or closing the reference signal correspondingly affects the transmission of the corresponding downlink channel.

In an example, in response to the downlink channel being a physical downlink control channel, PDCCH, and the reference signal being configured as QCL type D in a TCI state of CORESET associated with the PDCCH, the network device determines to transmit the PDCCH during the first period, and the user device determines to receive the PDCCH during the first period.

In another example, in response to the downlink channel being a semi-statically configured physical downlink shared channel, SPS, PDSCH, and the reference signal being configured as QCL type D in a TCI state of the SPS PDSCH, the network device determines to transmit the SPS PDSCH during the first period, and the user device determines to receive the SPS PDSCH during the first period.

These two examples may also be described as, in response to the downlink channel being a PDCCH or an SPS PDSCH, and the reference signal being configured with QCL type D in a TCI state of the downlink channel, the network device determining to transmit the downlink channel during the first period, the user device determining to receive the downlink channel during the first period.

In the above two examples, the downlink channel is still transmitted in the first period, so that the priority of transmitting the downlink channel is higher than the priority of the dynamic opening or closing of the reference signal by the network device, so that the dynamic opening or closing of the reference signal by the network device does not affect the transmission of the corresponding downlink channel.

In some possible embodiments, when the network device determines whether to transmit the downlink channel in the first period, it determines whether to transmit the downlink channel in the first period according to the downlink channel. Correspondingly, when the user equipment determines whether to receive the downlink channel in the first period, determining whether to receive the downlink channel in the first period according to the downlink channel.

The following is an exemplary illustration of three cases.

First kind:

receiving the PDCCH in the first period in response to the downlink channel being the PDCCH; or, in response to the downlink channel being an SPS PDSCH, receiving the SPS PDSCH within the first period.

Second kind:

stopping sending the corresponding PDCCH for some special CORESETs (e.g., CORESET corresponding to recovery search space) may cause communication interruption for the user equipment. The class of CORESET should not be affected by the network device dynamic switching reference signal.

In response to the downlink channel being a PDCCH corresponding to a set search space or a PDSCH scheduled by DCI for transmission in the set search space, the network device determines to transmit the downlink channel in the first period, and the user device determines to receive the downlink channel in the first period.

For example: the search space is set to be a search space for beam or link recovery, such that, in response to the downlink channel being a PDCCH corresponding to the search space for beam or link recovery or a PDSCH scheduled by DCI transmitted in the search space for beam or link recovery, the network device determines to transmit the downlink channel in the first period and the user device determines to receive the downlink channel in the first period.

It is conceivable that in another implementation, it may be agreed in the protocol that the reference signal configured as QCL type D in the TCI state in CORESET corresponding to the search space is set, and cannot be turned off. For example: the search space is set to be a search space for beam or link recovery, so that a reference signal configured as QCL type D in TCI state in CORESET corresponding to the search space for beam or link recovery cannot be turned off.

Third kind:

for SPS PDSCH configured to set priority, it should not be affected by network device dynamic switching reference signals. Thus, in response to the priority of the downlink channel being a set priority, the network device determines to transmit the downlink channel during the first period of time and the user device determines to receive the downlink channel during the first period of time. For example: in response to the priority of the downlink channel being the highest priority, the network device determines to transmit the downlink channel during the first period of time and the user device determines to receive the downlink channel during the first period of time.

It is conceivable that in another implementation, it may be agreed in the protocol that the reference signal configured as QCL type D in the TCI state corresponding to the SPS PDSCH configured to set priority cannot be turned off. For example: the reference signal configured as QCL type D in the TCI state corresponding to the SPS PDSCH configured as the highest priority may not be turned off.

In the above three cases, the downlink channel is still transmitted in the first period of time, and is not affected by the action of the network device for dynamically closing the reference signal, so that the action of the network device for dynamically opening or closing the reference signal does not affect the transmission of the corresponding downlink channel.

In some possible embodiments, when the network device determines to transmit the downlink channel in the first period, and the user device receives the downlink channel in the first period, the closing period is adjusted to make the transmission of the downlink channel perform smoothly, and in conjunction with fig. 3 (in fig. 3, the dotted line area corresponds to the second period, and the diagonal line filling area corresponds to the first period), the manner of adjusting the closing period may be one of the following:

in a first manner, it is determined that the closing period terminates at or before a first time, where the first time is a starting time of the first period. I.e. the closing period is terminated early.

The case shown in the first diagram in fig. 3, i.e., the case where the start position of the off period is earlier than the start position of the first period, is applicable.

The case shown in the second diagram in fig. 3, that is, the case where the start position of the off period overlaps the start position of the first period, is applicable. In this case, the off period is not turned on (i.e., is not in effect).

In a second mode, the starting time of the closing period is updated to be a second time, and the second time is the ending time of the first period. I.e. delay enabling the off period. The case shown in the second diagram in fig. 3, that is, the case where the start position of the off period overlaps the start position of the first period, is applicable.

In the embodiment of the disclosure, when the network device can dynamically switch the reference signal, and the closing period of the reference signal covers the first period, it is determined whether to receive the downlink channel in the first period, so as to realize that the downlink channel is not received to match with the dynamic closing behavior of the network device under the setting condition according to the use requirement, or the downlink channel is received and the dynamic control of the reference signal is correspondingly changed, so that on the premise that the network device can dynamically switch the reference signal, the control of the downlink channel is more reasonable, and the performance of wireless transmission is improved.

An embodiment of the present disclosure provides a method for receiving a downlink channel, which is performed by a user equipment, and fig. 4 is a flowchart illustrating a method for transmitting a downlink channel according to an exemplary embodiment, and as shown in fig. 4, the method includes steps S401 to S402:

S401, receiving indication information sent by a network device, wherein the indication information is used for indicating that a reference signal is closed and a closing period corresponding to the reference signal.

In some possible embodiments, configuration information (which may be received through radio link control RRC signaling) sent by the network device is received, where the configuration information is used to configure at least one spatial unit group, where the spatial unit group is a candidate spatial unit group that may be turned off, and each spatial unit group includes one or more Reference signals. The space unit group comprises a plurality of space units, and the space units are at least one of the following: antenna elements, ports, TRX chains, beams, panels.

S402, in response to the off period including a first period, the first period being all or part of a second period, the second period being a period in which the network device transmits a downlink channel, determining whether to receive the downlink channel in the first period.

The second period is information which is acquired by the user equipment through the received downlink channel configuration information, wherein the downlink channel configuration information is used for configuring the second period, and the second period is a period when the network equipment transmits a downlink channel.

In some possible embodiments, when the downlink channel is a semi-persistent scheduling (semi-persistent scheduling, SPS) physical downlink shared channel (physical downlink shared channel, PDSCH), the downlink channel configuration information is SPS PDSCH configuration information.

In some possible embodiments, when the ue determines whether to receive the downlink channel in the first period, it determines whether to receive the downlink channel in the first period according to the downlink channel and the reference signal.

In one example of the implementation of the method,

in response to the downlink channel being a physical downlink control channel, PDCCH, and the reference signal being configured as QCL type D in a TCI state of a CORESET associated with the PDCCH, the user equipment determines that the PDCCH is not received within the first period.

In the other of the examples described above, in the present example,

in response to the downlink channel being a semi-statically configured physical downlink shared channel, SPS, PDSCH, and the reference signal being configured as QCL type D in a TCI state of the SPS PDSCH, the user equipment determines not to receive the SPS PDSCH for the first period.

In the above two examples, the downlink channel is not received in the first period of time, and the downlink channel is matched with the dynamic closing behavior of the network device, so that the dynamic opening or closing behavior of the network device can correspondingly affect the receiving of the corresponding downlink channel.

In an example, in response to the downlink channel being a physical downlink control channel, PDCCH, and the reference signal being configured as QCL type D in a TCI state of CORESET associated with the PDCCH, the user equipment determines to receive the PDCCH within the first period.

In another example, in response to the downlink channel being a semi-statically configured physical downlink shared channel, SPS, PDSCH, and the reference signal being configured as QCL type D in a TCI state of the SPS PDSCH, the user equipment determines to receive the SPS PDSCH within the first period.

These two examples may also be described as, in response to the downlink channel being a PDCCH or an SPS PDSCH, and the reference signal being configured with QCL type D in a TCI state of the downlink channel, the user equipment determining to receive the downlink channel within the first period.

In the above two examples, the downlink channel is still transmitted in the first period, so that the priority of transmitting the downlink channel is higher than the priority of the dynamic opening or closing of the reference signal by the network device, so that the dynamic opening or closing of the reference signal by the network device does not affect the reception of the corresponding downlink channel.

In some possible embodiments, when the user equipment determines whether to receive the downlink channel in the first period, it determines whether to receive the downlink channel in the first period according to the downlink channel.

The following is an exemplary illustration of three cases.

First kind:

Second kind:

And responding to the downlink channel as the PDCCH corresponding to the set search space or the PDSCH scheduled by the DCI transmitted in the set search space, and determining to receive the downlink channel in the first time period by the user equipment.

For example: setting the search space as a search space for beam or link recovery, so that the user equipment determines to receive the downlink channel in the first period in response to the downlink channel being a PDCCH corresponding to the search space for beam or link recovery or a PDSCH scheduled by DCI transmitted in the search space for beam or link recovery.

Third kind:

for SPS PDSCH configured to set priority, it should not be affected by network device dynamic switching reference signals. Thus, in response to the priority of the downlink channel being a set priority, the user equipment determines to receive the downlink channel in the first period. For example: and in response to the priority of the downlink channel being the highest priority, the user equipment determines to receive the downlink channel in the first period.

In the above three examples, the downlink channel is still received in the first period of time, and is not affected by the action of the network device for dynamically turning off the reference signal, so that the action of the network device for dynamically turning on or off the reference signal does not affect the reception of the corresponding downlink channel.

In some possible embodiments, when the ue receives the downlink channel in the first period, the off period is adjusted to make the transmission of the downlink channel perform smoothly, and in conjunction with fig. 3 (in fig. 3, the dotted line area corresponds to the second period, and the diagonal line filling area corresponds to the first period), the manner of adjusting the off period may be one of the following:

In a second mode, the starting time of the closing period is updated to be a second time, and the second time is the ending time of the first period. I.e. delay enabling the off period.

The case shown in the second diagram in fig. 3, that is, the case where the start position of the off period overlaps the start position of the first period, is applicable.

An embodiment of the present disclosure provides a method for transmitting a downlink channel, which is performed by a network device, and fig. 5 is a flowchart illustrating a method for transmitting a downlink channel according to an exemplary embodiment, and as shown in fig. 5, the method includes steps S501 to S502:

s501, sending indication information to user equipment, wherein the indication information is used for indicating that a reference signal is closed and a closing period corresponding to the reference signal.

S502, in response to the off period including a first period, the first period being all or part of a second period, the second period being a period in which the network device transmits a downlink channel, determining whether to transmit the downlink channel within the first period.

Wherein the second period is a period in which the network device transmits a downlink channel. The network device may send downlink channel configuration information to the user device, where the downlink channel configuration information is used to configure the second period of time, so that the user device learns the second period of time.

In some possible implementations, when determining whether to transmit the downlink channel in the first period, the network device determines whether to transmit the downlink channel in the first period according to the downlink channel and the reference signal.

In one example of the implementation of the method,

in response to the downlink channel being a physical downlink control channel, PDCCH, and the reference signal being configured as QCL type D in a TCI state of a CORESET associated with the PDCCH, the network device determines not to transmit the PDCCH for the first period.

In the other of the examples described above, in the present example,

in response to the downlink channel being a semi-statically configured physical downlink shared channel, SPS, PDSCH, and the reference signal being configured as QCL type D in a TCI state of the SPS PDSCH, the network device determines not to transmit the SPS PDSCH for the first period.

In the above two examples, the downlink channel is not transmitted in the first period of time, and is matched with the dynamic behavior of the network device for closing the reference signal, so that the dynamic behavior of the network device for opening or closing the reference signal can correspondingly affect the transmission of the corresponding downlink channel.

In an example, in response to the downlink channel being a physical downlink control channel, PDCCH, and the reference signal being configured as QCL type D in a TCI state of CORESET associated with the PDCCH, the network device determines to transmit the PDCCH within the first period.

In another example, in response to the downlink channel being a semi-statically configured physical downlink shared channel, SPS, PDSCH, and the reference signal being configured as QCL type D in a TCI state of the SPS PDSCH, the network device determines to transmit the SPS PDSCH within the first period.

These two examples may also be described as, in response to the downlink channel being a PDCCH or an SPS PDSCH, and the reference signal being configured with QCL type D in a TCI state of the downlink channel, the network device determining to transmit the downlink channel within the first period.

In some possible embodiments, when the network device determines whether to transmit the downlink channel in the first period, it determines whether to transmit the downlink channel in the first period according to the downlink channel.

The following is an exemplary illustration of three cases.

First kind:

transmitting the PDCCH in the first period in response to the downlink channel being the PDCCH; or, in response to the downlink channel being an SPS PDSCH, determining to transmit the SPS PDSCH within the first period.

Second kind:

And responding to the downlink channel as the PDCCH corresponding to the set search space or the PDSCH scheduled by the DCI transmitted in the set search space, and determining to transmit the downlink channel in the first period by the network equipment.

For example: setting the search space as a search space for beam or link recovery, whereby the network device determines to transmit the downlink channel in the first period in response to the downlink channel being a PDCCH corresponding to the search space for beam or link recovery or a PDSCH scheduled by DCI transmitted in the search space for beam or link recovery.

Third kind:

for SPS PDSCH configured to set priority, it should not be affected by network device dynamic switching reference signals. Thus, in response to the priority of the downlink channel being a set priority, the network device determines to transmit the downlink channel within the first period. For example: in response to the priority of the downlink channel being the highest priority, the network device determines to transmit the downlink channel within the first period.

In the above three examples, the downlink channel is still transmitted in the first period of time, and is not affected by the action of the network device for dynamically turning off the reference signal, so that the action of the network device for dynamically turning on or off the reference signal does not affect the transmission of the corresponding downlink channel.

In some possible embodiments, when the network device determines that the downlink channel is transmitted in the first period, the off period is adjusted to make the transmission of the downlink channel perform smoothly, and in conjunction with fig. 3 (in fig. 3, the dotted line area corresponds to the second period, and the diagonal line filling area corresponds to the first period), the manner of adjusting the off period may be one of the following:
