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： An integrated terrestrial/non-terrestrial network may allow for enhanced network coverage. However, there are control and management challenges associated with an integrated terrestrial/non-terrestrial network because the network and user equipments (UEs) are no longer confined to only using conventional cellular communication via terrestrial transmit-and-receive points (T-TRPs). One challenge is how to perform beam management. In some embodiments, methods and systems are disclosed in which an indication of angular direction (e.g. beam direction) is provided by the T-TRP. The indication of angular direction may be used by a UE for communicating with a non-terrestrial TRP (NT-TRP), e.g. using beamforming. However, the methods are not limited to integrated terrestrial/non-terrestrial networks or the involvement of NT-TRPs, but apply more generally to indicating angular direction for directional communication.

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： 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： In order to minimize the control signaling overhead associated with transmitting CQI data from mobile stations to base stations in wireless communication networks supporting MU-MIMO, the CQI during MU-MIMO operation is estimated based on SU-MIMO CQI data, mobile station geometry data, and mobile station PMI (Precoding Matrix Index) data. More particularly, the base station maintains and updates a knowledge pool that correlates geometry data and learned impact of interfering precoder data to degradation of CQI values responsive to switching from SU-MIMO operation to MU-MIMO operations. Then, when the base station switches from SU-MIMO operation to MU-MIMO operation, it consults the knowledge pool to predict the degradation in CQI and subtracts them from the known, pre-switching SU-MIMO CQI feedback data for each relevant mobile station to predict the post-switching MU-MIMO CQIs for that mobile station.

摘要： Some embodiments of the present disclosure provide for use of a linear chirp signal as a basis for a sensing signal. Modification of the linear chirp signal by a signature function can allow a receiver of the sensing signal to determine an identity for a source of the sensing signal. Accordingly, upon processing the received sensing signal to obtain path parameter estimates, the receiver can direct a transmission of an indication of the path parameter estimates to the source of the sensing signal. Aspects of the present application relate to performing multi-node, multi-path channel estimation on the basis of processing the received sensing signal. Conveniently, the processing is performed with low complexity.

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.

摘要： A first user equipment (UE) is configured to receive from a base station a signaling comprising indication of one or more time-frequency resources and an indicator indicating a time gap, and transmit a transport block (TB) to a second UE using the one or more time-frequency resources. For each of the time-frequency resources, the first UE monitors a hybrid automatic repeat request (HARQ) feedback from the second UE, using a physical sidelink feedback channel (PSFCH) resource; and transmits to the base station a HARQ feedback report signal based on the HARQ feedback or absence thereof, in a physical uplink control channel (PUCCH), using a single PUCCH resource determined based on the time gap from a last one of the PSFCH resources.
