Abstract: A UE includes an EUTRA-CMR reception unit that receives a codec mode request (EUTRA-CMR) including a codec mode that is determined by an eNB in accordance with a radio condition of the UE, a mode switching notification unit that notifies an encoder of switching to the codec mode included in the received codec mode request; and a mode switching acknowledgement unit that transmits a response message to the eNB when confirming that the encoder switches the codec mode.

Abstract: A user equipment includes a receiver and a transmitter and is configured to report channel state information (CSI) to a base station in a communication system in which a plurality of downlink component carriers and at least one uplink component carrier are configured. The receiver receives, in a slot nTrigger, a trigger message that triggers reporting of the CSI for at least one unlicensed downlink component carrier of the plurality of downlink component carriers. The transmitter transmits, in a slot nReport, the CSI based on reference signals present in a slot nRS on the at least one unlicensed downlink component carrier. Responsive to the at least one unlicensed downlink component carrier being occupied for a period of time for a bursty downlink transmission, only the reference signals in the slot nRS are evaluated for the CSI, and other slots in the period of time are not evaluated for the CSI.

Abstract: The present disclosure relates to a method for paging coverage extension UEs in a cell controlled by a radio base station. At least one CE-specific paging possibility is defined for paging CE-UEs. The CE-UEs in the cell regularly monitor the at least one CE-specific paging possibility. When the radio base station determines to page all the user equipments in the cell, it pages the CE user equipments in the cell at the CE-specific paging possibility, using a coverage extension technique. The disclosure also relates to a method for paging a CE-UE, which performs radio measurements by a CE-capable user equipment to determine whether coverage extension is necessary. The radio base station is informed about whether the CE-capable user equipment needs coverage extension and then pages the CE-UEs applying or not applying a CE technique depending on whether coverage extension is necessary.

Abstract: Provided are wireless communication methods, a UE and an eNB. The wireless communication method performed by a UE includes transmitting transport block repetitions to an eNB, wherein one HARQ process includes multiple repetition sets of a transport block if one repetition set of the transport block is not enough for the eNB to successfully decode the transport block, each of the multiple repetition sets includes multiple repetitions of the transport block, each of the multiple repetition sets is followed by a feedback channel to indicate whether the transport block is successfully decoded by the eNB.

Abstract: Provided are systems and methods for transmitting data over a wireless channel from a data transmitting node to a data receiving node in a communication system. The data transmitting node comprises second-layer processing circuitry for receiving at least one second-layer SDU, to be mapped onto a resource allocated for data transmission, and for generating a second-layer PDU, including the at least one second-layer SDU and at least one second-layer control element, and first-layer processing circuitry for receiving the second-layer PDU generated by the second-layer processing circuitry and for mapping the second-layer PDU onto the resource allocated for data transmission. The data receiving node comprises first-layer processing circuitry for de-mapping at least one second-layer PDU, and second layer processing circuitry for receiving and parsing the second-layer PDU demapped by the first-layer processing circuitry, the second-layer PDU including at least one second-layer SDU, and at least one second-layer control element.

Abstract: The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.

Abstract: Provided are wireless communication methods and devices. In one embodiment, a wireless communication method performed by a wireless communication device comprises: transmitting a data packet repeatedly in multiple subframes including at least one normal subframe and at least one special subframe to another wireless communication device, wherein the available resources in the special subframe are different from that in the normal subframe, the data packet includes multiple modulated symbols which are divided into multiple modulated-symbol sets, in each subframe, each OFDM symbol is mapped by one of the modulated-symbol sets, and in every subframe, the modulated symbols in the same modulated-symbol set are mapped onto REs in one OFDM symbol in a fixed order. In another embodiment, multiple repetitions of the data packet are transmitted in each subframe, and in each special subframe, different repetitions are mapped onto REs with cyclic shift.

Abstract: In a terminal, based on a first parameter included in each of a plurality of downlink control signals, the first parameter indicating a cumulative count of code block groups (CBGs) configuring each of a plurality of transport blocks (TBs) assigned by the plurality of downlink control signals, a HARQ-ACK generation unit generates a response signal (HARQ-ACK) for each of the code block groups. A transmission unit collectively transmits the response signals for each of the code block groups.
