摘要： The present disclosure relates to a transmission device, a reception device, a transmission method and a reception method. The transmission device comprises a circuitry which, in operation, maps data and/or a reference signal onto a resource unit of a communication system. The resource unit includes subcarriers of a first numerology and subcarriers of a second numerology, each of the subcarriers being orthogonal to the other subcarriers of the same numerology, wherein the first numerology differs from the second numerology at least by a larger subcarrier spacing, and the subcarriers of the first and the second numerologies are frequency-multiplexed on a subcarrier basis. The transmission device further comprises a transmitter which, in operation, transmits the mapped data and/or reference signal in the resource unit, including subcarriers of the first and/or of the second numerology, and also transmits an indication of the mapping for the resource unit, which comprises references to subcarriers from the subcarriers of the first and/or the second numerology, where: for the first numerology, all subcarriers of the resource unit can be referenced, and for the second numerology, only inter-numerology-orthogonal subcarriers thereof can be referenced, each of the inter-numerology-orthogonal subcarriers being centrally aligned with a subcarrier of the first numerology.

摘要： A communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns includes a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.

摘要： The present disclosure relates to a transmission device, a reception device, a transmission method and a reception method. The transmission device comprises circuitry which, in operation, maps data and/or a reference signal onto resources of a communication system. The resources include subcarriers of a first numerology and a second numerology, wherein the first numerology and the second numerology differ at least by subcarrier spacing. The subcarriers of the first and the second numerologies are frequency-multiplexed on a subcarrier basis. The transmission device further comprises a transmitter which, in operation, transmits the mapped reference signals and/or data. Therein, the circuitry, in operation, assigns no transmit power to at least one subcarrier located between a subcarrier of the first numerology and a subcarrier of the second numerology.

摘要： The present disclosure relates to methods for reporting channel state information. The present disclosure also provides mobile stations for performing these methods, and computer readable media the instructions of which cause the mobile station to perform the methods described herein. For this purpose, the mobile station receives a trigger message that triggers the reporting of channel state information for at least one of the plurality of downlink component carriers, the trigger message being received in a subframe nTrigger, and reports the triggered channel state information for the at least one of the plurality of downlink component carriers based on reference signals present on the at least one of the plurality of downlink component carriers, in a subframe nReport later than nTrigger. The received trigger message indicates that the reference signals are present in a subframe nRS on the at least one of the plurality of downlink component carriers, where nTrigger≤nRS

摘要： The present disclosure relates to transmission and reception of data in a wireless communication system, the wireless communication system supporting aggregation of a plurality of component carriers and an additional carrier accessible by a listen before talk approach. In particular, monitoring is performed of a search space on a cross-scheduling component carrier for detecting downlink control information having a carrier identification field indicating the cross-scheduling component carrier as well as for detecting downlink control information with the carrier identification field indicating the additional carrier, wherein the search space is specified by a subset of resources, associated with carrier identification of the cross-scheduling component carrier but is not associated with carrier identification of the additional carrier. Then data are transmitted or received on the carriers in accordance with the received downlink control information.

摘要： The present disclosure relates to a method for transmitting and receiving a beamformed data transmission transmitted from a radio base station to a user equipment over an unlicensed band. The data transmission is transmitted by the radio base station within one or more resource blocks of a subframe, each resource block being composed of a plurality of resource elements. The beamformed data transmission is generated by the radio base station by 1) applying a first precoding for generating a beam directionality towards the user equipment to a subset of all the resource elements used for transmitting the data transmission in the subframe, and 2) applying a second precoding, different from the first precoding, to the remaining resource elements used for transmitting the data transmission in the subframe so as to achieve a radiation pattern different from the beam directionality towards the user equipment.

摘要： The present invention relates to configuring search spaces of at least two coexisting control channels in a communication system. In particular, the control channels are defined in at least partially overlapping regions, wherein the overlapping is in the time and/or frequency domain. This configuration enables coexistence of the at least two channels in the same resource grid and better utilization of the resources. Furthermore, it enables sharing of the reference signals.
