摘要： User equipment (UE) cooperation could improve latency, reliability, throughput, coverage and capacity in wireless communication systems. UE cooperation could include a group of UEs helping each other with transmissions through packet forwarding. Methods are provided that include receiving, by a UE in a predefined UE group, a plurality of packets. The plurality of packets includes a first packet that is scrambled using a UE specific identifier, and a second packet that is scrambled using a UE group specific identifier. The methods further include forwarding, by the UE, the plurality of packets.

摘要： 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.

摘要： Aspects of the present application provide methods and device for use in User Equipment (UE) cooperation. UE cooperation may include the cooperating UEs (CUEs) forwarding traffic to or from one or more target UEs (TUEs) with redundant signal transmissions or receptions. Methods involve a base station transmitting configuration information to at least one cooperative user equipment (CUE) and to a target user equipment (TUE). The configuration information includes an indication of resources for a sidelink (SL) transmission and a redundancy parameter for the SL transmission. The SL transmission is a transmission for the at least one CUE to forward a packet intended for the TUE. The base station also transmits the packet intended for the TUE, to a plurality of UEs comprising the at least one CUE and the TUE.

摘要： The present disclosure relates to uplink cooperative multi-User Equipment (UE) cooperative transmission such as Multiple-Input Multiple-Output (MIMO) transmission. Source data of a source UE that is to be transmitted via uplink cooperative transmission by multiple UEs, is transmitted to at least one cooperative UE over an SL. The source data is associated with an identifier for identifying the UE to the network equipment as a source of the source data. The multiple UEs transmit the source data and the identifier in an uplink direction to the network equipment. The network equipment receives the source data from the multiple UEs in a cooperative transmission such as cooperative MIMO transmission, and obtains the identifier for identifying the source UE as the source of the source data.

摘要： An enhanced User Equipment (UE) is formed by multiple UEs in a wireless communication network to assist one of the multiple UEs with communications, and involves UE cooperation between the multiple UEs. A capability, or at least one capability, of the enhanced UE is an enhanced capability relative to a capability of the UE that the enhanced UE is to assist. Information that is indicative of the (at least one) capability of the enhanced UE is obtained by a network device, and the network device communicates with the enhanced UE after obtaining the information. From a UE side, information indicative of a capability, or at least one capability, associated with the enhanced UE is transmitted, and the UE communicates with the network device after transmitting the information.

摘要： Multiple communication paths are established for communications between a User Equipment (UE) and a wireless communication network, before switching between those paths is initiated. Signaling that includes an explicit indication that the UE is to switch between the multiple communication paths is transmitted to and received by at least the UE for which the multiple communication paths were established. Responsive to the explicit indication, communications are switched between the communication paths. At least one of the communication paths includes a relay path between the UE and the wireless communication network through another UE. Establishment of the multiple paths in advance of the switching may be useful in enabling fast switching with low latency and/or no traffic loss.

摘要： In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions.

摘要： The present disclosure provides detailed specifications related to user equipment (UE) aggregation. As an example, a virtual UE (VUE) configuration, also referred to as a configuration for UE aggregation, that can be used by multiple UEs participating in UE aggregation may be communicated in a wireless communication network. The configuration may indicate, for example, that the UEs are to participate in UE aggregation, and indicate a first UE for splitting or combining data. In some embodiments the configuration may indicate protocol stacks for the multiple UEs to participate in UE aggregation, and an anchor point. The anchor point is associated with a layer in the protocol stack of a first UE of the multiple UEs, and implements data splitting and/or aggregation. As an alternative to the specific example of an anchor point, a configuration may indicate a function for splitting or aggregating data.
