Abstract: Method and apparatus for a user equipment (UE) operating in a serving cell is disclosed. The UE, in a first RRC_CONNECTED state, transmits an interest indication for a broadcast or a multicast service to a first serving cell. The interest indication includes at least some information associated with a broadcast or a multicast service. Upon entering a second RRC_CONNECTED state from an RRC_INACTIVE state, the UE may or may not send an interest indication to a second serving cell, taking into account the differences between the first and second serving cell, whether the second serving cell requested transmission of an interest indication, or whether the content of the second interest indication would be the same as the content of the first interest indication. A network node may retain UE context and other UE-related information after the UE has left an RRC_CONNECTED state, forward the information to another network node, and/or process the information when the UE re-enters the RRC_CONNECTED state.

Abstract: A method and apparatus are disclosed from the perspective of a first UE (User Equipment) to update Layer-2 Identities (IDs). In one embodiment, the method includes the first UE establishing a unicast link with a second UE, wherein a first Layer-2 ID of the first UE and a second Layer-2 ID of the second UE are used for data transmission and reception on the unicast link. The method further includes the first UE transmitting a Link Identifier Update Request message for the unicast link to the second UE, wherein the Link Identifier Update Request message includes a new first Layer-2 ID of the first UE. The method also includes the first UE receiving a Link Identifier Update Accept message for the unicast link from the second UE, wherein the Link Identifier Update Accept message includes a new second Layer-2 ID of the second UE. In addition, the method includes the first UE passing the new first Layer-2 ID of the first UE and the new second Layer-2 ID of the second UE down to the lower layer(s) after a Link Identifier Update Acknowledgement (ACK) message is passed to the lower layer(s) for transmission in response to reception of the Link Identifier Update Accept message.
