A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

A technique for wireless communications in a wireless system including: transmitting, from a second user device, unlicensed frequency transmission capability information, receiving an uplink transmission time for the second user device based on the unlicensed frequency transmission capability, receiving, at the second user device, a request to transmit a reservation transmission in an unlicensed frequency band based on a cancellation time capability of a first user device and the uplink transmission time, transmitting, by the second user device, the reservation transmission in the unlicensed frequency band, and transmitting, by the second user device, a higher priority uplink transmission in the unlicensed frequency band.

Disclosed are systems and methods for priority emergency messages over Wi-Fi. Particularly, the systems and methods may relate to an emergency message prioritization feature that may be used in association with Wi-Fi networks (for example, based on the 802.11 wireless standard). The feature may allow a station (STA) to request for such prioritization from an access point (AP) to allow the STA to receive priority in message transmission/receipt during emergency situations.

The subject technology provides for managing a data storage system. Commands are identified into as a first command type or a second command type. The commands identified as the first command type are assigned to a first queue, and the commands identified as the second command type are assigned to a second queue. After the commands from the first queue and the commands from the second queue are processed based on a scheduling ratio over a predetermined period of time, a write amplification factor, number of host read commands, and number of host write commands during the predetermined period of time are determined. The scheduling ratio is updated based on the write amplification, the number of host read commands, the number of host write commands, and a predetermined scheduling ratio factor. Subsequent commands are processed from the first queue and the second queue based on the updated scheduling ratio.

The present technology relates to a communication device and a communication method capable of transmitting data with a shorter waiting time. There is provided a communication device including a control unit that sets information regarding a priority of transmission on a plurality of links for each of access categories of data in a case where data is transmitted using a plurality of links corresponding to a predetermined frequency band. The present technology can be applied to, for example, a device constituting a wireless LAN system.

Methods for random access (RA) and a terminal device are provided. The method is executed by the terminal device and includes the following. Perform an RA procedure by using an RA-prioritization for slicing on condition that a use condition is satisfied.

Aspects of the disclosure provide an apparatus for wireless communication. The apparatus includes a transceiver and a processing circuit. The transceiver is configured to transmit and receive wireless signals. The processing circuit is configured to configure a field within a data unit for buffer information report, determine a first scale factor for scaling a first value indicative of buffered traffic of a first category, and a second scale factor for scaling a second value indicative of buffered traffic of a category, configure the field to include the first scale factor with the first value and the second scale factor with the second value, and provide the data unit to the transceiver for transmitting to another apparatus that allocates resources for transmission between the two apparatuses.

For a random access procedure (e.g., 2-step RACH and/or 4-step RACH), a network node may configure different physical random access preamble configurations (e.g., different PRACH occasions, preamble indexes, or preamble formats) for different user equipment (UE)/service groups that are associated with different UE priorities, UE types, service priorities, service types, and/or network slices. A UE may select a configuration to use to transmit the random access preamble based on the priority of the UE, the type of the UE, the priority of the service, the type of the service, and/or the network slice. In 2-step RACH, a network node may also configure different msgA PUSCH resources for different UE priorities, UE types, service priorities, service types, and/or network slices. The UE may transmit the random access preamble in accordance with the selected PRACH configuration as part of a contention based random access procedure.

Methods and devices for the prioritization of random access procedure messages for high priority devices, such as for mission critical services. One or more of transmit power, repetition, table selection, P1/BPSK enablement, TB scaling, channel access and CP extension can be adapted for prioritize devices and messages.

Disclosed are an information transmission method and device and a storage medium. The method includes: determining a plurality of beams for which clear channel assessment detection is to be performed; based on each beam of the plurality of beams, performing clear channel assessment detection in a beam direction corresponding to each beam; in response to presence of one or more beams among the plurality of beams for which the clear channel assessment detection is successful, determining a beam for transmitting information among the one or more beams for which the clear channel assessment detection is successful, and transmitting the information.
