Abstract: A method and apparatus for timing advance (TA) synchronization for uplink (UL) data transmissions are provided. A base station transmits a TA instruction to a UE. The TA instruction indicates one of at least two TA options. The first TA option indicates direct initial grant-free (GF) uplink (UL) data transmissions. The second TA option indicates indirect initial GF UL data transmissions with the UE initiating TA reference signaling for updating a TA parameter of the UE. The UE performs an initial GF UL data transmission to the base station based on the TA instruction.
Abstract: Embodiments of the present disclosure provide a mobility management method, apparatus, and system. An HA-C sends a first BA message to an MN, where the first BA message includes an address of a first HA-U; and the HA-C sends a configuration message to the first HA-U, where the configuration message includes an HoA and a CoA that are of the MN, so that the first HA-U performs tunnel communication with the MN according to the configuration message. In this way, an original proxy server or an original gateway completes only tunnel communication with the MN, and a newly-added proxy server completes control signaling interaction with a BU, thereby reducing load of the original proxy server or the original gateway, and resolving a prior-art problem that load of a proxy server or a gateway is relatively heavy.

Abstract: Embodiments of the present invention provide a method. When a target base station determines that the UE needs to be handed over from a source base station to a target base station and needs to perform a handover between a unicast bearer and a multicast/multicast bearer; because a progress of sending a data packet by using a target bearer may be slower than a progress of sending a data packet by using an original bearer, the target base station receives a data packet sent by using the original bearer and a data packet sent by using the target bearer, and when it is determined that a progress of receiving the data packet is faster than or equal to a progress of receiving the data packet by the target base station by using the target bearer, the target base station hands over the UE to the target bearer.

Abstract: Higher rates of data communication may be utilized for downlink than for uplink. However, the decoding complexity of Sparse Code Multiple Access (SCMA) may become prohibitive for very high rates, resulting from, for example, a large number of layers, for very large constellations, or a combination of the two. Methods and transmitters are provided herein for transmitting that has been generated to reduce complexity at the receiver and methods and receivers are provided herein for receiving and decoding a received signal with reduced complexity. The reduced complexity in part is provided by the ability to maintain real and imaginary parts of a transmitted signal independent from one another.
