Abstract: A data packet, that is to be transmitted in a dual connectivity (DC) or carrier aggregation (CA) based communications system, may include an indication to indicate whether the data packet is configured to be transmitted in a first frequency of a first carrier or a second frequency of a second carrier, and be transmitted, by a communication device, in the first frequency or the second frequency based on the indication. A data packet in the communications system may also be transmitted first in a first frequency higher than a second frequency, and then be retransmitted in the second frequency upon transmission failure of the data packet in the first frequency.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for multicasting traffic using multi-connectivity. A wireless network can send a downlink (DL) packet, which follows one path from a core network entity to a user equipment (UE) under current standards, to multiple base stations (BSs) and from each of the base stations to a UE. The UE receives the DL packet from whichever BS first delivers the DL packet, and then the UE sends a report reporting receipt of the DL packet back to all of the BSs. BSs that receive a report indicating the UE received the packet can drop the packet, even if they have not yet successfully delivered the packet. The same procedure can be used for an UL packet, which can be sent from a UE to multiple BSs, and from the BSs to a core network entity.

Abstract: A method for recovering from Sidelink relay failure is provided. A relay User Equipment (UE) detects a Radio Link Failure (RLF) or a Handover (HO) failure associated with a first base station when providing a relay service for a remote UE to indirectly communicate with the first base station. The relay UE sends a first command to the remote UE to indicate suspension of the relay service. The relay UE performs a Radio Resource Control (RRC) re-establishment procedure with the first base station or a second base station based on a cell search result. The relay UE sends a second command to the remote UE to indicate that the relay service is associated with the first base station or the second base station with which the RRC re-establishment procedure is performed.

Abstract: A method of connection establishment through a relay UE for a remote UE is proposed. The remote and relay UEs first perform discovery and establish a PC5 radio resource control (PC5-RRC) connection. Upon receiving a request from the remote UE, the relay UE and a serving gNB perform a relaying procedure for establishment of the remote UE's signalling radio bearer 1 (SRB1). The relay UE configures PC5 RLC channels for relaying of SRB1 towards the remote UE. The remote UE then enters an RRC_CONNECTED state. The remote UE and gNB establish security. The gNB configures additional data radio bearers (DRBs) for relaying. The relay UE configures PC5 RLC channels for relaying of the additional DRBs towards the remote UE. The DRBs can then be used for exchange of data between the remote UE and the gNB.
