It is to be understood that the transformation between the first transmission and the second transmission is in particular a transformation from the first transmission to the second transmission or vice versa by a frequency domain resource transformation and/or a time domain resource transformation and/or a transmission beam transformation and/or a transformation of polarization direction.

Further, in the case that the terminal is in a first transmission, the first configuration information includes relevant configuration information of the second transmission; or in case the terminal is in a second transmission, the first configuration information comprises 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 the following:

The corresponding polarization directions of the transmission beams comprise linear polarization, left-hand circular polarization, right-hand circular polarization, left-hand circular polarization and right-hand circular polarization;

a set of beam coverage areas corresponding to a second transmission under the first transmission beam coverage area, wherein the beam coverage areas in the set can be specifically identified through a beam index;

Further, the time domain resource includes at least one of:

A transmission occalasion of the first transmission;

And the transmission occalation of the second transmission.

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

The broadcast-multicast messages are of a plurality of types and different broadcast-multicast message types can be distinguished by a broadcast-multicast message type identification, and in one embodiment, the broadcast-multicast message types include at least one of:

Broadcasting a multicast service message;

Public messages;

Emergency communication;

Identical 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 manners, and in one embodiment, the first configuration information and/or the first indication is obtained by at least one of the following manners:

Pre-configuring;

SSB；

system information blocks (System Information Block, SIBs);

Radio resource control (Radio Resource Control, RRC) information;

a medium access control layer control unit (Medium Access Control Control Element, MAC CE);

Downlink control information (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 message.

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

In another embodiment, in the case that the terminal is a connected UE, the first configuration information and/or the first indication is obtained by at least one of the following means: SSB, SIB, 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 acquire the first configuration information and/or the first indication on the first transmission, or may acquire 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 acquire the first configuration information and/or the first indication on the second transmission, or may acquire 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 specific to the terminal (UE specific), or may be a common configuration, or part of the information in the first configuration information may be UE specific, while other information is configured in common.

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

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

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 by RRC configuration or pre-configuration. The first configuration information acquired by the UE on the second transmission is related configuration information of the first transmission, including: related 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 DCI scrambled by a specific radio network temporary identifier (Radio Network Temporary Identifier, RNTI), the UE is triggered/activated to switch from BWP where the second transmission is located to BWP where the first transmission is located, and to perform corresponding transmission. And the DCI scrambled by the specific RNTI is the first indication.

In another embodiment, the first and second transmission beam coverage areas are distinguished by BWP. When the UE on the second transmission receives DCI scrambled by a specific RNTI, the UE is triggered/activated to perform a transformation, and the DCI scheduled physical downlink shared channel (Physical downlink SHARED CHANNEL, PDSCH) transmission carries BWP related configuration information on which the first transmission is located. The DCI scrambled by the specific RNTI is the first indication, and the first indication carries first configuration information. After the UE successfully acquires the first configuration information, the UE transforms from the BWP where the second transmission is located to the BWP where the first transmission is located according to the configuration information or the predefined rule therein, and performs corresponding transmission. For the UE, the BWP related configuration information where the first transmission is located may be newly acquired first configuration information, or may be an update of the first configuration information that has been acquired before.

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

In another embodiment, when the UE is on the second transmission, a system message (System Information, SI) change indication is received, the SI change indication indicating that the common configuration information on the first transmission has changed. The UE transitions 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 ignore the SI change indication and not make a transformation, for example: at this time, the UE is in a non-connected state and needs to enter the connected state to perform transformation, and then the UE may ignore the SI change indication.

In another embodiment, the UE is assumed to be on the first transmission. If the corresponding paging message can be transmitted on the first transmission, when the network side generates the paging message corresponding to the UE, the network side equipment can send the paging message on the first transmission, and after the UE receives the paging message, the UE is transformed from the first transmission to the second transmission at present, and then subsequent transmission is performed; the paging message is the first indication.

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

In one embodiment, the first transmission beam coverage area is distinguished from the second transmission beam coverage area by frequency multiplexing, and the conversion between the first transmission and the second transmission is performed by BWP conversion, including:

Transitioning from the second transmission to the first transmission based on the BWP transition and suspending the validated partial bandwidth inactivity timer (BWP-inactivatytimer); or alternatively, the first and second heat exchangers may be,

Transition from the second transmission to the first transmission based on the BWP transition and terminate the validated BWP-inactivatytimer.

In another embodiment, the first transmission beam coverage area is distinguished from the second transmission beam coverage area by frequency multiplexing, and the conversion between the first transmission and the second transmission by BWP conversion comprises:

Transforming from the active downlink BWP of the second transmission to the first transmission based on the BWP transform;

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

The active downlink BWP (active DL BWP); or (b)

Initial downstream BWP (INITIAL DL BWP); or (b)

The determining of whether to timeout as active DL BWP or INITIAL DL BWP according to BWP-InactivityTimer may specifically include: if BWP-INACTIVITYTIMER times out, INITIAL DL BWP; if BWP-INACTIVITYTIMER does not timeout, it is active DL BWP.

Therefore, the embodiment of the application discloses a transmission conversion method, wherein the terminal executes conversion between the first transmission and the second transmission by acquiring the first configuration information and/or the first indication, thereby realizing conversion between broadcast multicast transmission and unicast transmission.

Fig. 6 shows a flow chart of another transmission transformation method according to an embodiment of the present application, and the execution subject of the method may be a terminal, which may also be referred to as a user equipment, in other words, the method may be executed by software or hardware installed in the terminal. 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, where the request message is used to request 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 first indication.

The step S402 may implement the same method embodiments as those of the steps S301 to S302 in fig. 5, and obtain the same technical effects, and the repeated parts will not be repeated here. The time for the terminal to acquire the first configuration information may be before or after step S401, or may be after the terminal acquires the first instruction, or may be simultaneously with the acquisition of the first instruction.

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; the network side equipment sends a first indication to the UE, wherein the first indication is used for indicating the UE to switch from the second transmission to the first transmission. At this point, the network-side device no longer schedules the UE's transmissions on the second transmission after the transition instant.

In one embodiment, the terminal, when making the 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 will be appreciated that the notification message may be sent before the terminal performs the transformation, after the terminal has performed the transformation, or during the transformation performed by the terminal.

It should be understood that the notification message may be sent before the terminal obtains the first configuration information and/or the first indication, or may be sent after the terminal obtains the first configuration information and/or the first indication. If the notification message is sent before the terminal obtains 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 the first configuration information is obtained or the first indication is obtained, 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 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, resending the first configuration information or sending the first indication to the terminal.

Therefore, the embodiment of the application provides a transmission conversion method, wherein the terminal acquires the first configuration information and/or the first indication by sending a request message, a notification message and/or a confirmation message to the network side equipment, and performs conversion between the first transmission and the second transmission, thereby realizing conversion between broadcast multicast transmission and unicast transmission.

Based on the above embodiment, further, in the case that the first configuration information obtained by the terminal in step S301 or S402 includes the first timer, the first timer is used to indicate the duration of corresponding transmission after transformation.

In one embodiment, the method further comprises:

When the terminal is converted from the third transmission to the fourth transmission, starting the first timer;

Upon expiration of the first timer, the terminal transitions from the fourth transmission back 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 alternatively

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 disabled; 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 a first indication;

the fourth transmission is shifted back and the first timer is reset. It should be understood that the terminal may not instruct the terminal to perform the corresponding transmission on the third transmission due to the second indication information acquired by the terminal is not the first indication, or may not instruct the terminal to perform the corresponding transmission on the third transmission due to other signaling received by the terminal, or may not receive the second indication information or other signaling that the terminal desires to receive after listening for a period of time, the terminal switches back to the fourth transmission and resets the first timer.

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

Or alternatively

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, and the last slot (slot) of each radio frame is a transmission occalage corresponding to the first transmission, and the remaining slots are transmission occalages corresponding to the second transmission.

For the UE on the second transmission, if the first indication is obtained, the UE may change to the transmission occalage where the first transmission is located at a proper time, for example, at the last slot of a certain radio frame, according to the first configuration information, so as to perform corresponding transmission. If the UE needs to perform the first transmission in a period of time, a first timer may be configured in the first configuration information, and before the first timer does not timeout, the UE performs the first transmission on the corresponding transmission occalation, and does not perform 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 is desired to receive data on the first transmission, it may autonomously switch to the transmission occalation on which the first transmission is located at an appropriate time, e.g., at the penultimate slot of a certain radio frame, and remain for a period of time, according to the pre-configuration information. Before the transformation, the UE reports a notification message informing the network side that the UE will perform the transformation and the duration of the transmission on the first transmission. During this duration, the UE transmits only on the transmission occalation corresponding to the first transmission, and does not transmit on the transmission occalation corresponding to the second transmission. The network side equipment receives the notification message, and the network side equipment terminates the second transmission with the UE before transformation; during this duration, the network side device does not schedule the UE for transmission on the transmission occalage corresponding to the second transmission.

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

(1) Upon expiration of the first timer, the UE needs to switch to the second transmission to receive signaling, which may be a first indication or other signaling;

(2) If the received signaling does not affect the UE or does not need to be converted to 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 the paging message corresponding to the UE, the network side device may send the paging message when the UE changes to the second transmission based on the above rule, and after receiving the paging message, the UE does not change to the first transmission, so as to perform transmission on the second transmission, and terminate the first timer.

Therefore, in the transmission conversion method, when the acquired first configuration information includes the first timer, the terminal can execute conversion between the first transmission and the second transmission based on the relevant rule of the first timer, so that conversion between broadcast multicast transmission and unicast transmission is realized.

It should be noted that, in the transmission conversion method provided in the embodiment of the present application, the execution body may be a transmission conversion device, or a control module in the transmission conversion device for executing the transmission conversion method.
