摘要： Provided herein are method and apparatus for configuration of a Reference Signal (RS) and a Tracking Reference Signal (TRS). An embodiment provides an apparatus for a user equipment (UE), comprising baseband processing circuitry configured to receive downlink control information (DCI) that indicates a number of slots for a Tracking Reference Signal (TRS, wherein the number of slots is based on a subcarrier spacing of a bandwidth part (BWP) in a current component carrier for the UE and receive TRS based on the number of slots indicated in the DCI, a frequency density of the TRS based on a bandwidth for the TRS, and a quasi co-location (QCL) relationship of the TRS, wherein the QCL relationship indicates that the TRS is Quasi-Co-Located (QCLed) with a Synchronization Signal (SS) block or a Channel State Information Reference Signal (CSI-RS).

摘要： Provided are a sounding reference signal (SRS) transmission method, a terminal device and a network device. When a slot configured by a network device through high-layer signaling does not include any time-domain resource available for SRS transmission or time-domain resources therein are not adequate, a terminal device may determine a slot for SRS transmission, thereby finding a proper uplink resource for sending an SRS to further ensure the uplink transmission performance. The method includes that: a terminal device receives downlink control information (DCI) from a network device, the DCI including SRS triggering signaling and the SRS triggering signaling indicating SRS transmission on at least one SRS resource set; and the terminal device transmits an SRS on a target SRS resource in the at least one SRS resource set in a slot meeting a first preset condition and after K slots from reception of the DCI, K being a nonnegative integer.

摘要： System, methods, and computer-readable media for validating and committing a shared O-RU configuration via a shared O-RU Operator. The shared O-RU Operator validates a partitioned configuration received from a tenant operator, with the ability to indicate to the tenant operator that the partitioned configuration is conformant to agreed-upon sharing rules and then commits the shared configuration to the shared O-RU. The shared O-RU operator shares the outcome of the commit operation to the tenant operator via defined operational-data that can be read by the tenant operator. A single radio in O-RAN is shared by multiple different operators and enables a neutral host to deploy a radio unit and then have that attached to different operators networks.

摘要： In order to efficiently schedule data transmission of a plurality of terminals, the wireless communication terminal receives a trigger frame indicating uplink multi-user transmission, and transmits an uplink multi-user PPDU (PLCP Protocol Data Unit) in response to the received trigger frame. In this case, the trigger frame and the non-legacy preamble of the uplink multi-user PPDU include remaining TXOP (Transmission Opportunity) time information of the uplink multi-user transmission process.

摘要： A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a radio resource control (RRC) message comprising a first parameter(s) used for configuring a first allocation table and a second allocation table. Each of the first allocation table and the second allocation table are used for defining a time domain allocation for a physical uplink shared channel (PUSCH) transmission. The receiving circuitry is also configured to detect in a UE specific search space, a downlink control information (DCI) format comprising first information used for indicating a row index to the first allocation table or the second allocation table. The DCI format is used for scheduling of the PUSCH. The UE also includes transmitting circuitry configured to perform, based on a detection of the DCI format, the PUSCH transmission based on either of the first allocation table or the second allocation table.
