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.

The present application provides a multimedia broadcast multicast service transmission method, including: a core network device determines a target terminal which is interested in a target MBMS; the core network device determines a cell associated with the target terminal; the core network device sends first information to an access network device to which the cell associated with the target terminal belongs, the first information is used to trigger the access network device to confirm whether the target MBMS needs to be received; establishes a broadcast connection with the access network device for the target MBMS, if second information from the access network device or the target terminal is received by the core network device, the second information is used to indicate the access network device needs to receive the target MBMS.

The invention provides a downlink resource allocation method, electronic equipment, a storage medium and a program product, relates to the technical field of communication, and is used for improving downlink transmission performance of a cell. The method comprises the following steps: under the condition that a first cell is in a long term evolution (LTE) state, distributing data symbols on a downlink subframe to a physical downlink shared channel (PDSCH) of the LTE; the data symbols are symbols used for transmitting user plane data in the subframe; and under the condition that the first cell is in a new air interface NR state, distributing a data symbol on a downlink subframe to a PDSCH (Physical Downlink Shared Channel) of the NR, and configuring the data symbol to be in a multimedia broadcast multicast service single frequency network MBSFN (Multimedia Broadcast Multicast Service Single Frequency Network) empty subframe format on an LTE (Long Term Evolution) side.

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 devices for wireless communications that support controlling feedback reporting associated with broadcast or multicast transmissions based on an indication of a non-numerical K1 (NNK1) in an associated transmission grant. In aspects, a base station transmits a multicast transmission grant including a NNK1 to a set of UEs. A UE of the set of UEs generates a feedback codebook for the multicast transmission and suspends transmission of the codebook until a reporting trigger event occurs based on the NNK1 received in the transmission grant. In aspects, the reporting trigger event includes receiving a subsequent multicast transmission grant with a valid K1, receiving a subsequent unicast transmission grant with a valid K1, or receiving a UE-specific multicast retransmission grant. In aspects, the UE determines a feedback resource for transmitting the suspended feedback codebook using the valid K1 in the trigger event. Other aspects and features are also claimed and described.

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.

A resource allocation method includes that: a terminal device receives first configuration information from a network device, where the first configuration information is used for determining a radio resource configuration of a Multimedia Broadcast Multicast Service (MBMS). A terminal device and a non-transitory computer readable storage medium are also provided.
