    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： Signaling to enable relay-based user equipment (UE) cooperation (UC) by a group of UEs, and a configuration including an adaptation protocol for processing of UC bearer traffic, are communicated in a wireless communication network. The UC bearer traffic includes a UC bearer and UC bearer attributes, and the UC bearer includes either a split bearer or a duplicated bearer indicated in the UC bearer attributes. In some embodiments, wireless network connectivity that is available for a relay link is determined, and the adaptation protocol is determined based on the determined connectivity. Signaling to enable configuration of the relay link in accordance with the connectivity and the adaptation protocol is communicated. A UE may receive signaling to configure the UE for such a relay link, and communicates traffic between a remote UE and the wireless communication network over the relay link.

    摘要： Methods and apparatuses are described for cooperation of two or more devices to improve the transmissions over a Uu interface. A source receives or transmits an indicator indicating a first mode of two modes of cooperation between the source apparatus and at least a first cooperating device. The two modes of cooperation includes a joint communication mode and a relay mode of cooperation. If the first mode is the joint communication mode, at least a portion of the data, intended for the intended recipient, is transmitted to at least the first cooperating device to be further transmitted by the first cooperating device to the intended recipient. A same or different portion of the data is transmitted to the intended recipient or to a second cooperating device to be further transmitted by the second cooperating device to the intended recipient.

    摘要： Systems and methods are disclosed for performing combined grant-free and grant-based UL resource allocation. In a particular embodiment, a network entity sends a first type of UL transmission resource assignment selected from two types of UL transmission resource assignment mechanisms to a UE for grant-free transmission and a second type of UL transmission resource assignment from two types of UL transmission resource assignment mechanism to a UE for grant based transmission. The network entity then receives a first data transmission from the UE for grant free transmission using an assigned transmission resource and a second data transmission from the UE for grant based transmission using an assigned transmission resources. Other embodiments pertain to changing the resource allocation scheme from grant free to grant based for a UE, or vice versa. Examples reasons for doing so may include HARQ re-transmissions.
