Beamforming methods and systems include determining a tradeoff curve between scanning beamwidth and transmission beamwidth based on a channel distribution for a base station. A set of scanning beams is selected based on the tradeoff curve. Devices around the base station are scanned for using the set of scanning beams. A set of transmission beams is selected for communications with the devices based on information received during the scanning. The set of transmission beams are used for transmission with a beamforming transmitter.

An apparatus, including at least one processor, and at least one memory storing instructions, the at least one memory and the instructions configured to, with the at least one processor, cause a network device to determine excess resources available for uplink transmissions to the network device and to use at least a portion of the excess resources for a beam refinement process associated with at least one radio beam usable for an information exchange with at least one terminal device.

A method which may be performed by a base station, may include obtaining a predicted transmission configuration indicator (TCI) subset for a user equipment (UE); and determining the TCI subset corresponding to the UE based on the predicted TCI subset. The step of obtaining the predicted TCI subset in the solution may be implemented by using a trained artificial intelligence model. Since the beams in the predicted TCI subset may fit the movement trend of the UE, then the target serving beam for the UE when performing serving beam switching may belong to the predicted TCI subset with a greater possibility, thus reducing the occurrence of high delay scenarios when the UE performs the serving beam switching, and thus reducing the beam switching delay.

A signal transmission method and a communication apparatus, to resolve a problem that an analog beam configuration switching process affects receiving and sending of a normal signal. The method includes: a terminal device receives first information from a network device, where the first information is used to schedule a first time domain resource and a second time domain resource, the first time domain resource is used to carry a first-type signal, the second time domain resource is used to carry a second-type signal, and a first beam configuration of the first-type signal is different from a second beam configuration of the second-type signal. The terminal device sends or receives a signal based on the first information, where the second-type signal is carried on a time domain resource other than N time domain units before and/or after the first time domain resource.

Devices, methods, and systems for scheduling of an enhanced sector level sweep (SLS). A wireless transmit/receive unit (WTRU) monitors beacon frames transmitted from one or more access points associated with the WTRU. The WTRU receive the beacon frames over multiple transmission sectors during a time interval. The WTRU then compiles the transmission sectors information in a list and ranks the sectors in the list, based on the sectors' characteristics. Then, the WTRU transmits the list over one sector of the list to the one or more access points.

Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) comprising a processor configured to receive a set of gap patterns, and measurement activities associated therewith, wherein each of the gap patterns includes an identifier for the measurement activity to be performed, and measure a signal pursuant to at least one of the gap patterns to obtain a measurement.
