Embodiments of the present application provide a unicast multicast conversion method and apparatus, and a processor-readable storage medium, wherein the unicast multicast conversion method comprises: receiving a Radio Resource Control (RRC) reconfiguration message sent by a first network node, when Multimedia Broadcast Multicast Service (MBMS) service data packets sent by the first network node are received through a multicast bearer and a User Equipment (UE) is in a connected state; reconstructing an MBMS Packet Data Convergence Protocol (MBMS PDCP) entity according to the RRC reconfiguration message; sending a reconfiguration completion message to the first network node so that the first network node converts the multicast bearer to a unicast bearer and sends the MBMS service data packets to the UE through the unicast bearer, the reconfiguration completion message being configured to characterize that reconstruction of the MBMS PDCP entity is accomplished by the UE; and receiving the MBMS service data packets sent by the first network node through the unicast bearer. The method realizes the conversion of the UE from receiving the MBMS service data packets through the multicast bearer to receiving the MBMS service data packets through the unicast bearer, thereby ensuring that no data packets are lost.

Various communication systems may benefit from the appropriate logging of measurements. For example, communication systems employing multimedia broadcast multicast service may benefit from logging multicast-broadcast single-frequency network measurements. A method can include logging, by a user equipment, a multicast-broadcast single-frequency network measurement corresponding to a logging period. The method can also include storing, at the time the multicast-broadcast single-frequency network measurement is made, cell measurement results.

The present disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for enabling a wireless system implementing multicast transmissions to control feedback reporting from multiple user equipments (UEs) and to address feedback codebook misalignment issues. In particular, aspects provide a multicast transmission grant including a plurality of feedback timing indicators (K1), where the multicast transmission grant is configured to configure different UEs for multicast transmission feedback reporting, where feedback codebooks sent from the different UEs in various uplink control transmission occasions have the same size. Other aspects and features are also claimed and described.

A communication method includes receiving, by a terminal device, first indication information. The first indication information is useable to indicate to the terminal device to disable a feedback function corresponding to a multimedia broadcast multicast service. The method further comprises disabling, by the terminal device, the feedback function corresponding to the multimedia broadcast multicast service.
