摘要： Current frame structures in Long-Term Evolution (LTE) and New Radio (NR) place some restrictions on the symbols transmitted in the frame, e.g. restrictions related to the duration of each symbol. Embodiments are disclosed in which multi-carrier symbols and/or single-carrier symbol blocks have configurable parameters, such as configurable length and/or configurable location, thereby allowing for more flexibility in the scheduling and transmission of the symbols and/or symbol blocks. Some embodiments aim to implement the configurable parameters in a way that tries to reduce signaling overhead.

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： 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： 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： 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： One embodiment of coordinated multiple relay link wireless communication with User Equipment (UE) cooperation involves coordinating, with a primary relay link between a UE and a wireless communication network, configuration of a secondary relay link between the UE and the wireless communication network; and communicating signaling to enable configuration of the secondary relay link in accordance with the coordinating. After the primary relay link and the secondary relay link have been configured, communications with the UE are coordinated over the primary relay link and the secondary relay link. Other embodiments may involve first and second relay links for a UE, and such relay links for a UE may be between the UE and a wireless communication network, or between the UE and another UE in the case of UE-to-UE relay links.

摘要： An apparatus and method for a wireless device to receive data in an eco state is provided. According to an embodiment of the disclosure, upon determining that data is to be transmitted to the wireless device in the eco state, a network node operates to transmit a unicast notification message to the wireless device in order to inform the wireless device of the impending data transmission. According to another embodiment of the disclosure, in response to receiving the unicast notification message, the wireless device operates to receive the data in accordance with the unicast notification message. To this end, the wireless device might for example try to receive data for a time period following the unicast notification message. Meanwhile, the wireless device may remain in the eco state.

摘要： Methods and systems are provided for signaling for semi-static configuration in grant free uplink transmissions. Radio resource control (RRC) signaling is used to provide information from a base station to a user equipment (UE) that configure the grant free transmission resource to be used by the UE. In some implementations, the RRC signaling may be used in conjunction with system information that is transmitted to all UEs and/or Downlink Control Information (DCI) that the UE needs to access subsequent to the RRC signaling. In some implementations, the DCI includes an activation or deactivation indicator that the UE monitors to determine when the UE is allowed to transmit to the BS or should stop transmitting. Implementations allow for grant free transmission resources to be configured on an individual user based and a group basis.
