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： Methods and apparatuses are disclosed for semi-persistent scheduling and configured grant transmission configurations. An example method, which is performed by a communication device, includes the steps of: transmitting, to a user equipment (UE), a radio resource control (RRC) signal or activation downlink control information (DCI) signal for semi-persistent scheduling (SPS) or configured grant (CG) transmission configuration; and transmitting, to the UE, a physical layer control signal comprising an indication of one or more parameters for SPS or CG transmission.

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 devices for performing role change are described. Dynamic signaling is used. Example formats for uplink and downlink signaling is also described. In some examples, an electronic device (ED) receives, via dynamic signaling, from a first serving cell, with which the ED initially has a primary connection, a role change trigger. The role change trigger causes the ED to use a connection with a second serving cell, with which the ED initially has a secondary connection, as the primary connection instead of the first serving cell.

摘要： Aspects of the present application use diversity of more than one TCI state, QCL assumption, precoder and/or SRI on the network side to enable multiple transmission beams in a transmission period having multiple transmission opportunities to provide robust beam transmission from the network side. An example of transmission opportunities in a transmission period may be OFDM symbols in a slot. Aspects of the present application use diversity of more than one TCI state, QCL assumption, precoder and/or SRI at the UE to enable the UE to transmit multiple transmission beams in a configured transmission period having multiple transmission opportunities to provide robust transmission from the UEs. When using multiple transmission beams, in the event that data transmitted on one beam cannot be decoded (e.g. due to beam blockage, poor radio conditions, etc.), data transmitted on other beams can still be decoded successfully.

摘要： The present disclosure relates, in part, to non-terrestrial communication systems, and in some embodiments to the integration of terrestrial and non-terrestrial communication systems. Non-terrestrial communication systems can provide a more flexible communication system with extended wireless coverage range and enhanced service quality compared to conventional communication systems. A method representative of aspects of the present application includes receiving, by an apparatus connected in a first sub-system, from a radio access network, configuration information for performing a channel condition measurement on a second sub-system, reporting, by the apparatus to the radio access network, channel condition measurement of a downlink reference signal received from the second sub-system, transmitting, by the apparatus, a wireless transmission to the second sub-system responsive to the channel condition measurement meeting a predefined condition.
