Further, in case the terminal is in a first transmission, the first configuration information comprises configuration information related to the second transmission; or, in a case that the terminal is in a second transmission, the first configuration information includes configuration information related to the first transmission.

The first configuration information acquired by the terminal may include various types of information, and in one embodiment, the first configuration information includes at least one of:

a transmission occast of the second transmission.

Further, the transmission beam is a beam used by the network side device for transmission, and provides transmission signal coverage for a certain area, where the area is a beam coverage area of the transmission beam.

The broadcast-multicast message has a plurality of types, and can be distinguished from different broadcast-multicast message types by a broadcast-multicast message type identifier, and in one embodiment, the broadcast-multicast message type includes at least one of:

broadcasting a multicast service message;

a public message;

emergency communication;

the same configuration information among multiple beams;

the same configuration information among multiple cells.

The terminal may obtain the first configuration information and/or the first indication in a plurality of ways, and in one embodiment, the first configuration information and/or the first indication are obtained in at least one of the following ways:

pre-configuring;

SSB；

a System Information Block (SIB);

radio Resource Control (RRC) information;

a Medium Access Control layer Control unit (MAC CE);

downlink Control Information (DCI);

paging (Paging) messages.

The first configuration information and the first indication may be carried in the same signaling or message, or may be carried in different signaling or messages.

In an embodiment, in a case that the terminal is a non-connected UE, namely idle/inactive, the first configuration information and/or the first indication is obtained by at least one of: SSB, SIB1 and Paging messages.

In another embodiment, in a case that the terminal is a connected (connected) UE, the first configuration information and/or the first indication are obtained by at least one of: SSBs, SIBs, paging messages, RRC, and DCI.

Further, the first configuration information and/or the first indication is obtained on at least one of the following transmissions:

the first transmission;

the second transmission.

In one embodiment, when the terminal is on the first transmission, the terminal may obtain the first configuration information and/or the first indication on the first transmission, and may also obtain the first configuration information and/or the first indication on the second transmission.

Conversely, when the terminal is on the second transmission, the terminal may obtain the first configuration information and/or the first indication on the second transmission, and may also obtain the first configuration information and/or the first indication on the first transmission.

It should be understood that the first configuration information acquired by the terminal may be configured specifically for the terminal (UE specific), or may be configured in common, or some information in the first configuration information may be configured in common for the UE specific, and other information is configured in common.

Further, the set of beam coverage areas corresponding to the second transmission under the first transmission beam coverage area or the set of cells under the first transmission beam coverage area in the first configuration information represents a set of beam coverage areas or a set of cells corresponding to the second transmission which can be transformed with the first transmission.

In an embodiment, if the first configuration information is configured by UE specific, a transmission corresponding to a beam coverage area set corresponding to the second transmission under the first transmission beam coverage area or a cell set under the first transmission beam coverage area is a second transmission transformed by the UE. And if the first configuration information is the terminal specific configuration, the beam coverage area set corresponding to the second transmission under the first transmission beam coverage area or the cell set under the first transmission beam coverage area is the beam coverage area or the cell to which the second transmission is performed after the terminal is converted.

In an embodiment, the first transmission beam coverage area and the second transmission beam coverage area are distinguished by BWP of a frequency domain resource, and the first configuration information acquired by the UE is acquired through RRC configuration or pre-configuration. The first configuration information acquired by the UE in the second transmission is the relevant configuration information of the first transmission, and includes: the relevant configuration information of the BWP where the first transmission is located, for example: BWP identification (BWP ID), SCS, normal CP, frequency domain location of BWP, bandwidth occupied by BWP, etc. When the UE receives a DCI scrambled by a specific Radio Network Temporary Identifier (RNTI), triggering/activating the UE to switch from the BWP where the second transmission is located to the BWP where the first transmission is located, and performing corresponding transmission. The DCI scrambled by the specific RNTI is the first indication.

In another embodiment, the first and second transmission beam footprints are distinguished by BWP. When the UE in the second transmission receives DCI scrambled by a specific RNTI, the UE is triggered/activated to perform transformation, and the Physical Downlink Shared Channel (PDSCH) transmission scheduled by the DCI carries configuration information related to the BWP where the first transmission is located. The DCI scrambled by the special RNTI is the first indication, and the first indication carries first configuration information. And after the UE successfully acquires the first configuration information, the UE is converted from the BWP where the second transmission is located to the BWP where the first transmission is located according to the configuration information or a predefined rule, and corresponding transmission is carried out. For the UE, the configuration information related to the BWP where the first transmission is located may be the newly acquired first configuration information, or may be an update to the first configuration information that has been acquired before.

Further, if the UE antenna supports only left-hand circular polarization (LHCP), then the first transmission beam footprint should support at least LHCP.

In another embodiment, when the UE is on the second transmission, after receiving a System Information (SI) change indication, the SI change indication indicates that the common configuration Information on the first transmission has changed. The UE switches from the second transmission to the first transmission to receive the common configuration information; the SI change indication is the first indication. Or the UE may also ignore the SI change indication and not make a change, for example: at this time, the UE is in the non-connected state, and needs to enter the connected state before the UE can change, so that the UE may ignore the SI change indication.

In another embodiment, assume that the UE is on the first transmission. If the corresponding paging message can be transmitted in the first transmission, when the network side generates the paging message corresponding to the UE, the network side device may send the paging message in the first transmission, and after receiving the paging message, the UE switches from the current first transmission to the second transmission for subsequent transmission; the paging message is the first indication.

In another embodiment, assuming that the UE is in the first transmission, if the UE cannot transmit the corresponding paging message in the first transmission and the network side device knows that the UE is in the first transmission at this time, the network side device may send the first indication in the first transmission, and after the UE changes to the second transmission, the network side device sends the paging message in the second transmission for subsequent transmission.

In one embodiment, the first transmission beam footprint is distinguished from the second transmission beam footprint by frequency multiplexing, and transforming between the first transmission and the second transmission by BWP transformation, comprises:

transitioning from the second transmission to the first transmission based on the BWP transition and suspending the active partial bandwidth inactivity timer (BWP-inactivity timer); or,

transition from the second transmission to the first transmission based on the BWP transition and terminate the active BWP-InactivityTimer.

In another embodiment, the first transmission beam footprint is distinguished from the second transmission beam footprint by frequency multiplexing, and transforming between the first transmission and the second transmission by BWP transformation, comprises:

transitioning from an active downlink BWP for the second transmission to the first transmission based on the BWP transition;

after a certain time, when the terminal transitions from the first transmission back to the second transmission, the BWP on the second transmission is one of:

the active DL BWP (active DL BWP); or

Initial downlink BWP (initial DL BWP); or

According to BWP-inactivity timer, determining whether the timeout is active DL BWP or inactive DL BWP may specifically include: if BWP-inactivytytytimer times out, it is initial DL BWP; if BWP-inactivity timer is not timed out, it is active DL BWP.

Therefore, the terminal executes the conversion between the first transmission and the second transmission by acquiring the first configuration information and/or the first indication, thereby realizing the conversion between the broadcast multicast transmission and the unicast transmission.

Fig. 6 shows a schematic flow chart of another transmission transformation method according to an embodiment of the present application, where an execution subject of the method may be a terminal, and the terminal may also be referred to as a user equipment. As shown in fig. 6, the method may include the following steps.

Step S401, a terminal sends a request message to a network side device, wherein the request message is used for requesting the network side device to send the first configuration information and/or the first indication;

step S402, the terminal acquires first configuration information and/or a first instruction.

Step S402 may implement the same method embodiment as steps S301 to S302 in fig. 5, and obtain the same technical effect, and repeated portions are not described herein again. The time for the terminal to acquire the first configuration information may be before or after step S401, or after the terminal acquires the first indication, or simultaneously with the acquisition of the first indication.

In one embodiment, assuming that the UE is on the second transmission, if the UE desires to receive the broadcast service of interest on the first transmission at this time, the UE may send a request message to the network side device; and the network side equipment sends a first indication to the UE, wherein the first indication is used for indicating the UE to be converted from the second transmission to the first transmission. At this point, the network side device no longer schedules the UE for transmission on the second transmission after the transition time.

In one embodiment, when the terminal performs a transition between the first transmission and the second transmission, the method further comprises:

and sending a notification message to the network side equipment, wherein the notification message is used for notifying the network side equipment of the transformation to be performed by the terminal.

It should be understood that the notification message may be sent before the terminal performs the transformation, after the terminal performs the transformation, or during the transformation performed by the terminal.

It should be understood that the notification message may be sent before the terminal acquires the first configuration information and/or the first indication, or may be sent after the terminal acquires the first configuration information and/or the first indication. If the notification message is sent before the terminal acquires the first indication, the network side device may not send the first indication after receiving the notification message. If the notification message is sent after the terminal acquires the first configuration information and/or the first indication, the network side device does not schedule the terminal to transmit on the second transmission after receiving the notification message.

In one embodiment, after obtaining the first configuration information or obtaining the first indication, the method further comprises:

and the terminal sends a confirmation message to the network side equipment.

In one embodiment, after the network-side device sends the first configuration information or sends the first indication to the terminal, the method further includes:

starting a second timer;

if the network side equipment receives the confirmation message sent by the terminal before the second timer is overtime, the second timer is invalid;

and if the network side equipment does not receive the confirmation message sent by the terminal before the second timer is overtime, the network side equipment resends the first configuration information or sends the first indication to the terminal.

Therefore, the embodiment of the present application provides a transmission conversion method, where a terminal acquires first configuration information and/or a first indication by sending a request message, a notification message, and/or an acknowledgement message to a network side device, and performs conversion between first transmission and second transmission, thereby implementing conversion between broadcast multicast transmission and unicast transmission.

Based on the foregoing embodiment, further, in the case that the first configuration information acquired by the terminal in step S301 or S402 includes a first timer, the first timer is configured to indicate a duration of performing corresponding transmission after the conversion.

In one embodiment, the method further comprises:

when the terminal is switched from the third transmission to the fourth transmission, starting the first timer;

upon expiration of the first timer, the terminal transitioning back from the fourth transmission to the third transmission, the first timer failing;

wherein the third transmission and the fourth transmission are at least one of:

the third transmission is the first transmission and the fourth transmission is the second transmission;

or,

the third transmission is the second transmission and the fourth transmission is the first transmission.

In another embodiment, the method further comprises:

upon expiration of the first timer, the terminal transitions from a fourth transmission back to the third transmission and performs at least one of:

acquiring second indication information or other signaling expected to be received by the terminal on the third transmission, wherein the terminal is kept on the third transmission, and the first timer is invalid; wherein the second indication information is used for indicating the terminal to keep the third transmission, and the other signaling indicates the terminal to perform corresponding transmission on the third transmission; the second indication may be the first indication;

transition back to the fourth transmission and reset the first timer. It should be understood that, the terminal may be that the second indication information acquired by the terminal is not the first indication, or that other signaling received by the terminal does not indicate the terminal to perform corresponding transmission on the third transmission, or that the terminal does not receive the second indication information or other signaling that the terminal desires to receive after monitoring for a period of time, then the terminal changes back to the fourth transmission, and resets the first timer.

Wherein the third transmission and the fourth transmission are at least one of:

or,

In one embodiment, it is assumed that the first transmission beam coverage area and the second transmission beam coverage area are distinguished by time domain resources, a last slot (slot) of each radio frame is a transmission occase corresponding to the first transmission, and the remaining slots are transmission occases corresponding to the second transmission.

For the UE in the second transmission, if the first indication is obtained, the UE may switch to the transmission occast of the first transmission at a suitable time, for example, at the penultimate slot of a certain radio frame, according to the first configuration information, and perform corresponding transmission. If the UE needs to perform the first transmission within a period of time, a first timer may be configured in the first configuration information, and before the first timer does not time out, the UE performs the first transmission on the corresponding transmission occase without performing the second transmission; upon expiration of the first timer, the UE transitions from the first transmission to the second transmission.

And vice versa.

In another embodiment, for a UE on the second transmission, if it desires to receive data on the first transmission, it may autonomously switch to the transmission occast on the first transmission at a suitable time, for example, at the penultimate slot of a certain radio frame, according to the preconfigured information, and keep for a certain period of time. Before the transformation, the UE reports a notification message to inform the network side device that the UE will transform and the duration of the transmission on the first transmission. During this duration, the UE transmits only on the transmission occase corresponding to the first transmission, and does not transmit on the transmission occase corresponding to the second transmission. The network side equipment receives the notification message, and terminates the second transmission with the UE before the network side equipment is converted; during this duration, the network side device does not schedule the transmission of the UE on the transmission occase corresponding to the second transmission.

In another embodiment, assuming that the UE is in the first transmission, if the paging message cannot be transmitted in the first transmission, the network side device knows that the UE is in the first transmission at this time, and the network side device has configured a first timer to the UE in advance when the UE is in the second transmission, and specifies:

(1) The UE needs to change to a second transmission to receive signaling when the first timer expires, where the signaling may be a first indication or other signaling;

(2) If the received signaling has no influence on the UE or the UE does not need to be converted into the second transmission for subsequent transmission, the UE automatically converts back to the first transmission after receiving the signaling, continues to transmit on the first transmission, and resets the first timer.

Further, if the network side device has a paging message corresponding to the UE, the network side device may send the paging message based on the above specification when the UE switches to the second transmission, and after receiving the paging message, the UE does not switch to the first transmission any more to perform transmission on the second transmission, and terminates the first timer.

Therefore, in the transmission conversion method according to the embodiment of the present application, when the first configuration information includes the first timer, the terminal may perform conversion between the first transmission and the second transmission based on the relevant specification of the first timer, thereby implementing conversion between broadcast multicast transmission and unicast transmission.

It should be noted that, in the transmission conversion method provided in the embodiment of the present application, the execution main body may be the transmission conversion apparatus, or a control module in the transmission conversion apparatus for executing the transmission conversion method. In the embodiment of the present application, a transmission conversion method executed by a transmission conversion apparatus is taken as an example to describe the transmission conversion apparatus provided in the embodiment of the present application.

Fig. 7 is a schematic structural diagram of a transmission conversion apparatus according to an embodiment of the present application, and as shown in fig. 7, the apparatus includes: a transceiver module 501 and an execution module 502.

The transceiver module 501 is configured to obtain first configuration information; the transceiver module 501 is further configured to obtain a first indication, where the first indication is used to indicate that a transition is performed between a first transmission and a second transmission; the execution module 502 is configured to perform a transformation between a first transmission and a second transmission;

wherein the first transmission is a broadcast multicast transmission, the second transmission is a unicast transmission, and the transmission transformation device is simultaneously in a beam coverage area of the first transmission and a beam coverage area of the second transmission.

Therefore, the embodiment of the present application provides a transmission conversion apparatus, which performs conversion between first transmission and second transmission by acquiring first configuration information and/or a first indication, thereby implementing conversion between broadcast multicast transmission and unicast transmission.

Based on the above embodiment, further the first and second transmission beam footprints are distinguished by at least one of:

frequency domain multiplexing;

time domain multiplexing;
