Abstract: Aspects of the present application provide methods and devices for use in User Equipment (UE) cooperation. A packet transmitted between a base station and a UE or between UEs includes a packet destination identifier that identifies a destination of the packet. A receiving the packet from a base station or another UE can determine whether the UE is the destination of the packet. When the UE is the destination of the packet, the UE decodes the packet. When the UE is not the destination of the packet, the UE forwards the packet to another UE. The packet may include a packet source identifier that can be used by the destination to determine where the packet originated. In some instances, the cooperative UEs do not need to decode the entire packet to be able to determine the destination of the packet and therefore can forward the packet along with less processing.

Abstract: Systems and methods of synchronization channel design for radio access network (RAN) slicing are described. According to embodiments, a user equipment (UE) receives, from a first transmit point in a radio access network (RAN), a first synchronization signal over a first synchronization channel. The first synchronization channel is associated with a first RAN slice of a plurality of RAN slices in the RAN. The plurality of RAN slices comprise a second RAN slice associated with a second synchronization channel. The first synchronization channel and the second synchronization channel are different from a default synchronization channel of the first transmit point.

Abstract: Embodiments of the present application pertain to control information for scheduling a transmission resource for downlink and uplink communications between one or more TRP and one or more UE. One Physical Downlink Control Channel (PDCCH) for DL control information transmission is assumed to carry at least one assignment or scheduling information block for at least one Physical Downlink Shared Channel (PDSCH) for DL data transmission or for at least one Physical Uplink Shared Channel (PUSCH) for UL data transmission. Embodiments of the present application provide methods of providing configuration information that can be used by a user equipment (UE) to determine transmission mode for the PDSCH and PUSCH as well as information to determine where to monitor for the PDSCH, PUSCH and PUCCH information.

Abstract: A user equipment (UE) may determine that a transmission resource includes a first orthogonal frequency-division multiplexing (OFDM) symbol that is configured as a downlink symbol or as flexible, where the transmission resource is allocated for uplink (UL) transmissions during a time duration, and includes K transmission occasions (TOs). The UE may transmit a first UL transmission in the transmission resource omitting the first OFDM symbol. The first UL transmission includes K repetitions to be transmitted in the respective K TOs, and the K repetitions includes an initial transmission and at least one retransmission of the initial transmission.

Abstract: This application provides a UCI sending and receiving method and a communications apparatus. In the method, an association relationship between a PUCCH and a PUSCH is established, so that when resources of the PUSCH and the PUCCH overlap, a terminal device can determine UCI on which PUCCHs can be transmitted by multiplexing the resource of the PUSCH. A network device may receive the UCI on the PUSCH. Because the network device may know in advance which PUCCHs and PUSCHs are sent to the network device, the network device can demodulate and decode a signal on the received PUSCHs, to successfully obtain UCI. The network device can make a proper decision based on the UCI.
