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： Method and devices are provided for wireless communication. A method involves obtaining, by a receive user equipment (UE), configuration information relating to a sidelink transmission between the first UE and a second UE, the configuration information for indicating to the first UE that the sidelink transmission is not associated with any corresponding sidelink control information (SCI). A further step involves receiving, by the receive UE, the sidelink transmission from the second UE using time and frequency resources indicated by the configuration information. Another method involves obtaining, by a transmit UE, configuration information relating to a sidelink transmission between the first UE and a second UE, the configuration information for indicating to the first UE that the sidelink transmission is not associated with any corresponding SCI and transmitting, by the first UE, the sidelink transmission to the second UE using time and frequency resources indicated by the configuration information.

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 to handling latency-sensitive traffic, in Ultra-Reliable Low Latency Communication (URLLC) for example, during measurement gaps. Latency-sensitive traffic is detected at a user equipment (UE), and transmission or reception associated with the latency-sensitive traffic is performed at the UE during a time period in which a measurement gap has been configured for the UE to perform measurement of received signal strength. The transmission or reception may be performed instead of or in addition to the measurement. Other embodiments that involve shortening measuring times and shortening or avoiding switching times associated with communication resource switching, for example, are also disclosed.
