摘要： Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of channel access procedure based on the channel access priority class (CAPC). The method comprises receiving scheduling information from a second device, the scheduling information at least indicating resources allocated for a transmission from the first device to the second device, a channel access type for the transmission and an expected access priority for the transmission. The method further comprises comparing the expected access priority with an access priority of data in a buffer of the first device and determining use of the resources based on the comparison. In this way, the Channel Occupancy Time (COT) sharing can be used only for the data with higher or equal priority to avoid unintended usage of the grant on unlicensed band and coexistence fairness among nodes with different types of traffic to be transmitted may be achieved.

摘要： Example embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for uplink (UL) positioning of idle or inactive terminal device. In example embodiments, a location management functionality determines a configuration related to an uplink positioning reference signal for a terminal device in an idle or inactive state. The location management functionality indicates the configuration to a location measurement unit. Further, the location management functionality causes a base station to inform the terminal device of the configuration via a paging message to trigger uplink positioning of the terminal device based on the configuration while the terminal device is in the idle or inactive state, or to release the uplink positioning while the terminal device is in the idle or inactive state.

摘要： Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for multi-cell positioning. In example embodiments, a method is provided. The method includes transmitting, from a first network device, a first reference signal to a terminal device served by a second network device. The method further includes receiving a second reference signal from the second network device. The method further includes determining a first time difference between a time at which the first RS is transmitted and a time at which the second reference signal is received. In addition, the method includes transmitting information on the first time difference to a location server. As such, the location server can determine positioning information about the terminal device.

摘要： Example embodiments relate to wideband communications based on availability assessment. A method for communication comprises performing availability assessment on a set of configured frequency subbands to obtain an availability result, the availability result indicating that at least one of the set of configured frequency subbands is available for a period of time for transmission of intended information and transmitting supplementary information that has been prepared using the at least one frequency subband during a first portion of time within the period of time. The method also comprises preparing the intended information based on the availability result and transmitting the prepared intended information using the at least one frequency subband during a second portion of time following the first portion of time within the period of time. As such, the processing of the intended information can be adapted depending on the dynamic available subband(s) indicated by the availability result.
