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： 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： By defining more SCS options and Discrete Fourier Transform (“DFT”) options for transmissions in future networks, there arises cause to select from among the options, with aspects of the channel as guidance for the selection. In addition, new CP designs may be defined for use with the new SCS options and the new DFT options along with methods of selecting a CP design appropriate to a particular situation. The new CP designs may be shown to have smaller CP overhead when compared to the known CP designs used for known combinations of an SCS option with an FFT size option. New sampling frequency design options and new system basic timing options may also be defined, along with methods of making appropriate selections from among these options. Control signaling using higher layers may be used to distribute configuration options that include multiple SCS options, CP duration options, sampling frequency options and DFT size options per sub-band. Later, layer 1 signaling may be used to specify a particular option from among the multiple options.

摘要： The power requirements of user equipments (UEs) are expected to increase as their capabilities increase. Some power saving methods have previously been proposed, but are limited by the radio resource control (RRC) protocol and do not address the power consumption associated with having to transition between different RRC states. In some embodiments described herein, there are not different RRC states, but instead a single RRC state. Within that single RRC state, there are different modes of operation, e.g. a default low power operation mode and an enhanced power operation mode. In some embodiments, the UE switches from the default operation mode to the enhanced operation mode on an on-demand basis (e.g. based on the communication capability required by the UE), and then returns back to the default operation mode.

摘要： Current frame structures in Long-Term Evolution (LTE) and New Radio (NR) are not designed to accommodate full duplex (FD) communication. Embodiments are disclosed in which frame structures are provided that support FD communication and frequency division duplex (FDD) communication and time division duplex (TDD) communication. In some embodiments, there is defined two separate and independent frame structures: a frame structure for reception (e.g. a downlink frame structure) and a frame structure for transmission (e.g. an uplink frame structure).

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： System and methods are disclosed in which pilots are used to assist in identifying grant-free uplink transmissions originating from the same UE. In one embodiment, a base station receives a grant-free uplink transmission that carries initial data from a user equipment and an initial pilot. The initial pilot is successfully decoded and the initial data is unsuccessfully decoded. The successfully decoded initial pilot and the unsuccessfully decoded initial data are stored in memory. Another grant-free uplink transmission carrying retransmission data from the user equipment and a retransmission pilot is then received. The retransmission pilot is successfully decoded and used to identify the successfully decoded initial pilot in the memory and the unsuccessfully decoded initial data. The retransmission data and the unsuccessfully decoded initial data are used to successfully decode the initial data.
