Embodiments of the present invention provide systems and methods for performing priority service access between EHT non-AP STAs or MLDs using EDCA or UORA parameter sets corresponding to enabled links that can be used to derive priority access (e.g., contention window) information of enabled links for NSEP or LL wireless communication. The EHT non-AP STAs or MLDs can enable, configure, and update priority access for NSEP or LL services using protected action frames or beacon frames, for example. Deriving priority information from the EDCA or UORA parameters carried in protected action frames or beacon frames advantageously avoids increasing the overhead of beacon frames and prevents degradation of spectrum efficiency while supporting NSEP or LL priority services.

The application provides a method performed by a user equipment in a wireless communication system, comprising: receiving first configuration information for transmitting uplink data signals from a base station, determining uplink transmission resources based on a first downlink signal associated with uplink transmission resources indicated in the first configuration information, and transmitting the uplink data signals.

An apparatus (e.g., an access point (AP) establishes a plurality of links comprising a primary link and at least a secondary link. The apparatus transmits a management frame on the primary link to indicate a multi-link capability of the AP. The apparatus configures the secondary link for one or more non-AP stations (STAs), which are capable of operating on the primary link and the secondary link, with multi-link capability and operating parameters through an association procedure on the primary link.

Many aspects pertaining to various apparatuses, methods, and computer-readable medium are described herein. Some aspects pertain to wireless communication between various apparatuses, which may include one or more access points (APs) and/or one or more stations (STAs). The one or more APs and/or one or more STAs may have one or more radios. Some aspects pertain to various features related to such one or more radios. Some aspects pertain to certain technologies related to uplink (UL) communication(s) and/or downlink (DL) communication(s). The written description and appended drawings provide detailed descriptions regarding these and many other aspects.

Apparatuses, methods, and systems are disclosed for power headroom reporting for multiple uplink carriers. One apparatus includes a transceiver that receives a configuration of a plurality of UL carriers for a serving cell. The first apparatus includes a processor that determines that a PHR has been triggered, where the PHR for the serving cell is determined to be a virtual PHR. The processor determines a default power control parameter set for the serving cell and calculates a PHR for the serving cell. Here, calculating the PHR includes calculating a virtual PH based on the default power control parameter set. The processor transmits (via the transceiver) the calculated PHR for the serving cell.

A random access method and apparatus, the method comprising: a terminal device sending a first message to a network device, the first message including a random access preamble and uplink information; the random access preamble occupies at least one first symbol in the time domain, and the uplink information occupies at least one second symbol in the time domain, the one first symbol comprises a first cyclic prefix (CP) and at least one first information segment, and the one second symbol comprises a second CP and at least one second information segment. The random access method and apparatus of an implementation of the present disclosure may reduce signaling overhead during random access.

A method and a device in a node used for wireless communication are disclosed in the present disclosure. A first node transmits a first sequence and a first radio signal, the first sequence being associated with the first radio signal, the first sequence being transmitted on a first random-access channel, and a first bit block being used for generating the first radio signal; receives a second radio signal, the second radio signal comprising a first information block; and transmits a second sequence and a third radio signal, the second sequence being associated with the third radio signal, and the second sequence being transmitted on a second random-access channel, the first bit block being used for generating the third radio signal; the first information block comprises a first sequence index, the first sequence index corresponds to the first sequence.

Methods and apparatuses for switching duplex mode during random access (RA). A method for operating a user equipment (UE) includes receiving a system information block (SIB) for a cell that provides information for a first configuration of slots for transmissions or receptions in a half-duplex mode and a random access (RA) procedure, determining a UE capability for transmitting and receiving in a full-duplex mode, and determining a transmission of a channel based on the RA procedure and the first configuration of slots. The method further includes transmitting the channel including information of the UE capability using the RA procedure and receiving information for a second configuration of slots for transmissions or receptions in the full-duplex mode.

A system for satellite communication is disclosed. The system includes a base terminal and a mobile terminal configured to communicate via a communication satellite relay. The base terminal and the mobile terminal include a receiver and a transmitter. At least one of the base terminal or the mobile terminal further includes an artificial intelligence engine configured to receive status or instruction data based on a received signal, determine an instruction or command based on the received data, prepare instruction data or updated status data, and send an instruction signal or status signal based on the instruction data or updated status data. The artificial intelligence engine utilizes a machine learning model and may generate the machine learning model.

A user equipment may be configured to perform active interference cancellation for random-access channel. In some aspects, the user equipment may receive, from a base station, physical layer random-access channel (PRACH) configuration information including one or more active interference cancellation (AIC) parameters for applying AIC to a PRACH message to the base station. Further, the user equipment may transmit, to the base station, the PRACH message with one or more AIC subcarriers based on the one or more AIC parameters.
