Abstract
Disclosed are methods for multicast broadcast service. One embodiment of the subject application provides a method performed by a UE, comprising receiving data packets in a first cell in a first mode, sending a data receiving status report during or after a handover and/or during or after a data transmission mode switching, receiving missing data packets during the data transmission mode switching and/or during the handover, and receiving data packets in a second cell in a second mode. Related apparatuses are also disclosed.
Claims20
A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive data packets in a first mode;
- send a data receiving status report during data transmission mode switching,
- wherein the data receiving status report indicates data packets that are missing during the data transmission mode switching;
- receive the missing data packets in a second mode after the data transmission mode switching;
- and
- receive next data packets in the second mode.
A base station (BS) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the BS to:
- transmit data packets in a first mode;
- receive a data receiving status report during data transmission mode switching,
- wherein the data receiving status report indicates data packets that are missing during the data transmission mode switching;
- transmit the missing data packets in a second mode after the data transmission mode switching;
- and
- transmit next data packets in the second mode.
A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- receive data packets in a first transmission mode in a first cell;
- send a data receiving status report during or after a handover from the first cell to a second cell or during or after a data transmission mode switching from the first transmission mode to a second transmission mode,
- wherein one of the first transmission mode and the second transmission mode is a Point-to-Point (PTP) mode and the other of the first transmission mode and the second transmission mode is a Point-to-Multipoint (PTM) mode;
- receive missing data packets in the second transmission mode after or during the data transmission mode switching or after or during the handover;
- and
- receive next data packets in the second transmission mode.
A base station (BS) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the BS to:
- transmit data packets in a first transmission mode to a user equipment (UE);
- receive a data receiving status report from the UE during or after a handover from a first cell to a second cell or during or after a data transmission mode switching from the first transmission mode to a second transmission mode,
- wherein one of the first transmission mode and the second transmission mode is a Point-to-Point (PTP) mode and the other of the first transmission mode and the second transmission mode is a Point-to-Multipoint (PTM) mode;
- transmit missing data packets to the UE in the second transmission mode during or after the data transmission mode switching or during or after the handover according to the data receiving status report;
- and
- transmit next data packets to the UE in the second transmission mode.
