摘要： A method is disclosed for a wireless transceiver comprising a plurality of transceiver antenna elements and configured to operate in a communication network. The method comprises dynamically assigning (from the plurality of transceiver antenna elements) a first set of transceiver antenna elements allocated for channel sensing and a second set of transceiver antenna elements allocated for communication, performing channel sensing using the first set of transceiver antenna elements, and operating the wireless transceiver based on a result of the performed channel sensing. For example, dynamically assigning the first and second sets of transceiver antenna elements may comprise (in a non-communication mode of the wireless transceiver) letting the first set comprise all of the transceiver antenna elements and letting the second set be empty, (in a communication transmission mode of the wireless transceiver) letting the first set comprise a first subset of the transceiver antenna elements and letting the second set comprise a second subset of the transceiver antenna elements, wherein the first and second subsets are nonoverlapping, and (in a communication reception mode of the wireless transceiver) letting the first set comprise a third subset of the transceiver antenna elements and letting the second set comprise a fourth subset of the transceiver antenna elements, wherein the third and fourth subsets are non-overlapping or overlapping. Corresponding apparatus, wireless transceiver, access node, user device and computer program product are also disclosed.

摘要： A beamforming method is disclosed of a multi-antenna transmitter configured for operation in a listen-before-talk (LBT) environment.
The method comprises transmitting—in transmission resources of a collection of one or more transmission resources corresponding to an LBT sensing event—according to a primary emission pattern (e.g., a primary beam) having a main lobe in a primary angular direction associated with a channel path towards an intended receiver, and transmitting according to one or more secondary emission patterns. The one or more secondary emission patterns—when accumulated over the collection of transmission resources corresponding to the LBT sensing event—are configured to indicate channel occupancy in angular directions other than the primary angular direction.
In some embodiments, the one or more secondary emission patterns comprises a plurality of secondary emission patterns (e.g., a plurality of secondary beams). Transmitting according to the one or more secondary emission patterns may comprise executing a sweep of the respective secondary beams over the collection of transmission resources corresponding to the LBT sensing event.
In some embodiments, the one or more secondary emission patterns consists of a single secondary emission pattern (e.g., an omni-directional emission pattern).
Corresponding apparatus, transmitter, network node, wireless communication device, and computer program product are also disclosed.
