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: In a terminal that judges whether to trigger a handover from a serving cell to another cell, a RSRQ/RSRP measurer measures a first received quality value by using a cell-specific reference signal transmitted from the neighboring cell or a second received quality value by using a cell-detection reference signal transmitted from the neighboring cell. An offset adder calculates a third received quality value by adding an offset value to the second received quality value. A judging circuitry judges whether the first received quality value or the third received quality value satisfies a handover triggering condition with reference to the cell-specific reference signal. A transmitter transmits trigger information to the neighboring cell in order to activate handover from a serving cell to the neighboring cell, based on the judgement results.

Abstract: The present disclosure relates to a resource allocation procedure, performed between a user equipment and radio base station. The UE is configured with at least one numerology scheme, each associated with parameters partitioning time-frequency radio resources into resource scheduling units differently. The UE is configured with logical channels each of which is associated with at least one numerology scheme. A receiver of the UE receives from the radio base station an uplink scheduling assignment, which indicates uplink radio resources usable by the UE. A processor of the UE determines for which numerology scheme the received uplink scheduling assignment is intended based on the received uplink scheduling assignment. The processor performs a logical channel prioritization procedure by allocating the assigned uplink radio resources to the configured logical channels and by prioritizing those logical channels that are associated with the numerology scheme for which the uplink scheduling assignment is intended.

Abstract: In a base station, a DCI generation unit selects one pattern (mode) for use when data is allocated from among a plurality of patterns (modes) of a resource area where data (PDSCH) is allocated, and a transmission unit provides notification about setting information regarding the plurality of patterns (modes) by signaling of a higher layer and provides notification about the one pattern (mode) selected from the plurality of patterns by a downlink control signal (DCI).

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: An integrated circuit includes generation circuitry and transmission circuitry. The generation circuitry uses a reference size for a search space to generate downlink control information (DCI) in a first DCI format used for sidelink communications. The transmission circuitry transmits the DCI in the first DCI format mapped on the search space. When a second DCI format used for base station communications is mapped on the search space and the second DCI format is larger than the first DCI format, the reference size for the search space is based on the second DCI format. When a third DCI format used for sidelink communications is mapped on the search space and the third DCI format is larger than the first DCI format, and the second DCI format larger than the third DCI format is not mapped on the search space, the reference size is based on the third DCI format.

Abstract: A user equipment in a wireless communications system supporting direct communication between user equipments selects a sidelink destination group (ProSe destination) associated with a sidelink logical channel having a highest logical channel priority among sidelink logical channels, which have data available for transmission in a sidelink control period (SC period) and which have not previously been selected in the same SC period, wherein each of the sidelink logical channels belongs to a sidelink destination group, each of the sidelink logical channels is allocated to a logical channel group (LCG) depending on a priority of said each sidelink logical channel and on a priority of the logical channel group, and the logical channel group is defined per sidelink destination group. The user equipment allocates radio resources to sidelink logical channels belonging to the selected sidelink destination group in decreasing priority order, and transmits the data using the allocated radio resources.

Abstract: In a terminal, a control unit decides a sequence used for an uplink control channel, in accordance with uplink control information, and a transmission unit transmits the uplink control information using the sequence. Here, the sequence is calculated using cell identification information that identifies the cell to which the terminal belongs, and subcell-specific information relating to at least one subcell included in the cell.
