摘要： The present disclosure relates to communication technology, and discloses a resource selection method and apparatus in a carrier aggregation scenario, a device, and a storage medium. The method includes: evaluating target resources in a target resource set at a second time instant according to a selected resource or scheduled resource on a second carrier. The target resource set includes a selected resource on a first carrier as indicated at a first time instant, and the second time instant is earlier than the first time instant. According to the present disclosure, the selected resource on the current carrier is evaluated according to the latest selected resource or scheduled resource on another carrier, at least before transmission on the selected resource of the current carrier. If the currently selected resource cannot be used for transmission, resource reselection can be triggered. In this way, the problem of inaccurate resource exclusion when the terminal device initially selects resources can be solved, and the accuracy of resource selection in the carrier aggregation scenario can be improved.

摘要： Provided in the embodiments of the present application are a wireless communication method and a terminal device. A transmitting-end terminal can transmit a plurality of CSI-RSs in one slot, such that an optimal spatial domain transmission filter of the transmitting-end terminal can be selected on the basis of the transmitted CSI-RSs, or, an optimal spatial domain receiving filter of a receiving-end terminal can be selected on the basis of the transmitted CSI-RSs. The wireless communication method comprises: a first terminal device using, in a first slot, a spatial domain transmission filter to transmit M CSI-RSs to a second terminal device, wherein the M CSI-RSs are used to select a target spatial domain transmission filter, or, the M CSI-RSs are used to select a target spatial domain receiving filter, and one of the M CSI-RSs occupies N time-domain symbols, M and N being positive integers, and M> 1.

摘要： The disclosure provides a method for channel detection, devices, and a storage medium, which can be applied to a terminal device on sidelink (SL). The method includes the following. Monitor a channel before a time-unit boundary and/or after the time-unit boundary, and determine, according to a channel monitoring result, whether to perform blind detection in a time unit next to the time-unit boundary. When it is determined or it is determined with a high probability there is no SL transmission in the next time unit according to the channel monitoring result, the terminal device does not need to perform blind detection in the next time unit, which can reduce the number of times of blind detections performed by the terminal device, thereby reducing power consumption of the terminal device.

摘要： Embodiments of the present disclosure provide a wireless communication method and a first device. The method includes: adjusting, by the first device, a contention window corresponding to each priority of at least one priority, based on feedback information for a first channel transmitted within a reference time unit or a reference time period. A transmission mode of the first channel includes at least one of a groupcast transmission mode, a multicast transmission mode, or a broadcast transmission mode. For groupcast, multicast, or broadcast scenarios, the method provided by the present disclosure can not only be used to adjust a contention window, but also avoid the use of a same contention window when a plurality of first devices performs Listen Before Talk (LBT), thereby facilitating a reduction in interference between the plurality of first devices.
