Abstract: Disclosed is a base station capable of appropriately configuring a resource on which an EPDCCH is located when soft combining is applied. The base station includes a configuration section that configures an EPDCCH set in a plurality of subframes, where the EPDCCH set is formed of ECCEs to which control information (assignment information) transmitted over the plurality of subframes is assigned. The base station includes an assignment section that assigns the control information to any of the ECCEs in each of the plurality of subframes.

Abstract: Provided are D2D wireless communication methods and UEs therefor. In one embodiment, the D2D wireless communication method performed by a UE includes continuing D2D transmission by using a resource from a resource pool allocated for mode 2 operation when switching from mode 1 operation to mode 2 operation. In another embodiment, the D2D wireless communication method performed by a UE includes performing D2D transmission by using a resource from a resource pool allocated for mode 2 operation, wherein the resource pool is indicated by a dedicated RRC signaling transmitted by an eNB, a SIB transmitted by an eNB, a PD2DSCH transmitted by other UE(s), and/or pre-configuration, and the dedicated RRC signaling, the SIB, the PD2DSCH and the pre-configuration are in descending order in priority when determining the resource pool.

Abstract: The invention relates to a method for dynamically indicating a TDD reconfiguration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication.

Abstract: The invention relates to methods for communicating within a communication system when re-configured from a source to a target uplink/downlink configuration. The invention is also providing mobile station for performing these methods, and computer readable media the instructions of which cause the mobile station to perform the methods described herein. Specifically, the invention suggests to perform PUSCH transmissions in response to Downlink Control Information, DCI, transmissions such that the source uplink/downlink configuration is applied to PUSCH transmissions relating to DCI transmissions received up to and including subframe N−6, a predefined uplink/downlink configuration is applied to PUSCH transmissions relating to DCI transmissions received during subframes N−5 to N−1; and the target uplink/downlink configuration is applied to PUSCH transmissions relating to DCI transmissions received from subframe N onward.

Abstract: The invention relates to the allocation of radio resources by a transmitting user equipment to perform a plurality of direct SL transmissions to one or more receiving user equipments. The allocation of radio resources within a SC period is restricted, for the SC period, by a maximum number of SL processes with which a transmitting user equipment is configured. A plurality of SL grants is acquired. Among the acquired SL grants a number of those SL grants is selected that have most recently been acquired before the start of the subsequent SC period. A plurality of SL processes is associated such that each of the plurality of SL process is associated with a different one of the selected number of SL grants. For each of the plurality of the SL processes, the radio resources are allocated. Each of the plurality of SL transmissions comprises at least one SCI transmission and at least one data transmission over the SL interface.
