Abstract: Methods and apparatuses for predictive beam management in a wireless communication system. A method of operating a user equipment (UE) includes receiving configuration information for transmission configuration indication (TCI) states; receiving information indicating a number of TCI states and a number of corresponding TCI state application times; and determining, for one or more TCI states in the number of TCI states, at least one of downlink (DL) quasi-co-location (QCL) properties for DL communication and an uplink (UL) spatial domain filter for UL communication. The method further includes at least one of receiving, using the determined DL QCL properties, DL channels starting at the corresponding TCI state application times and transmitting, using the determined UL spatial filter, UL channels starting at the corresponding TCI state application times.

Abstract: Methods and apparatuses for beam management after channel setup. A method of operating a user equipment (UE) includes receiving at least one of synchronization signal/physical broadcast channel block (SSB) or channel state information reference signal (CSI-RS), measuring the at least one of the SSB or the CSI-RS, and determining downlink (DL) quasi-co-location (QCL) properties for DL communication based on the at least one of the SSB or the CSI-RS. The method further includes determining an uplink (UL) spatial domain filter for UL communication, receiving DL channels using the determined DL QCL properties until only one of only one joint TCI state or only one DL TCI state is configured, activated, or indicated to the UE, and transmitting UL channels using the determined UL spatial domain filter until only one of only one joint TCI state or only one UL TCI state is configured, activated, or indicated to the UE.

Abstract: A user equipment, a method, and computer-readable media. The UE, which includes a transceiver with a plurality of antenna panels, is configured to determine a link quality of a serving antenna panel. If the link quality of the serving panel is below a quality threshold, resources are allocated from the serving antenna panel to another antenna panel during a sweeping period to identify one or more beams of a target antenna panel for resuming communications. Measurements for a set of beams of the other antenna panel are obtained, during the sweeping period, with the allocated resources. The other antenna panel can be determined to be the target antenna panel based on the obtained measurements. The UE can switch from the serving antenna panel to the target antenna panel, select the one or more beams based on the obtained measurements, and resume the communications on the selected one or more beams.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE).The application discloses methods and apparatuses for transmitting and receiving a preamble based reference signal. The method for transmitting a preamble based reference signal comprises: generating a main preamble sequence; generating an auxiliary preamble sequence, wherein, on a predefined resource, a synthesized signal of the main preamble sequence and the auxiliary preamble sequence is equal to a predefined preamble based reference signal; and transmitting the main preamble sequence and the auxiliary preamble sequence based on a filter-bank multi-carrier modulation. According to the embodiments of the application, the main preamble sequence and the auxiliary preamble sequence are appropriately designed so that the synthesized signal on the predefined resource is equal to the predefined preamble based reference signal. In this way, the predefined reference signal may be obtained at the receiving end by using the intrinsic interference of FBMC modulation, thereby making an efficient channel estimation.

Abstract: A method for transmitting signal based on a filter bank multi-carrier (FBMC) modulation, a method for receiving signal based on the FBMC modulation, and a corresponding transmitting device and receiving device are disclosed. The method includes preprocessing determined symbols in a data block, modulating the preprocessed data block with the FBMC modulation, truncating the modulated data block to remove a part or all of tailing data therefrom, and transmitting the truncated modulated data block, from which the part or all of tailing data has been removed, and the determined symbols are affected by the truncating of the modulated data block. The data block includes at least one symbol. The method relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE).

Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). Various examples of the present disclosure provide a method of allocating sounding reference signal (SRS) resources. A base station of a target cell receives information of first cell edge terminals in an adjacent cell transmitted by the adjacent cell. The base station allocates SRS resources for a terminal in the target cell according to information of second cell edge terminals in the target cell and the information of the first cell edge terminals, and transmits information of the allocated SRS resources to the terminal. According to the mechanism, when there are cell edge terminals in both the target cell and the adjacent cell, it can be guaranteed that all SRS resources allocated to cell edge devices in the target cell are orthogonal to those allocated to cell edge devices in the adjacent cell. Thus, the impact of pilot contamination on system performances may be remarkably reduced.
