Abstract: If repetition transmission is applied to a response signal for a downlink data signal and an uplink signal, the uplink signal is repeatedly transmitted using a certain number of consecutive subframes starting with a first subframe, at which the repetition transmission of the uplink signal starts, and the response signal is repeatedly transmitted using at least the certain number of consecutive subframes starting with a second subframe, at which the repetition transmission of the response signal starts. The first subframe is set to be the same as the second subframe.

Abstract: A user equipment, a base station and respective methods are provided. The user equipment receives a physical uplink shared channel (PUSCH) config information element (IE) in form of radio resource control (RRC) signaling, the PUSCH config IE being applicable to a particular bandwidth part. The user equipment configures a table which is defined by a PUSCH time domain resource allocation list IE carried in the received PUSCH config IE, the table comprising rows, at least one row comprising a first set of values related to allocated time-domain resources for a plurality of PUSCH transmissions. The user equipment receives downlink control information (DCI) signaling carrying a time-domain resource assignment filed with value m, wherein the value m provides a row index m+1 to the RRC configured table. The user equipment determines allocated time-domain resources for the plurality of PUSCH transmissions based on the index of the slot carrying the received DCI.

Abstract: The present disclosure relates to a user equipment, a base station and respective methods. The user equipment (UE) receives a single uplink grant for a plurality of PUSCH transmissions. The single uplink grant comprises an antenna port field with an index value that is to be used for the plurality of PUSCH transmissions. The UE determines time-domain resources based on the received uplink grant. The determined time-domain resources prescribe a number of PUSCH transmissions and a length of each of the number of PUSCH transmissions. The UE transmits the number of PUSCH transmissions using the determined time-domain resources. Each of the number of PUSCH transmissions comprises at least one front-loaded demodulation reference signal, DMRS. In particular, the UE determines a number of symbols to be used for each of the at least one front-loaded DMRS of the number of PUSCH transmissions based on the received index value, and, in case at least two of the number of PUSCH transmissions have different lengths, and in case different numbers of symbols are permissible for each of the at least one front-loaded DMRS, the UE transmits the same or a smaller number of PUSCH transmissions such that, for none of the comprised at least one front-loaded DMRS, a different determined numbers of symbols is used.

Abstract: A user equipment (UE) comprises processing circuitry which operates a function that involves monitoring of a downlink control channel of an unlicensed radio cell for information intended to the UE. The unlicensed radio cell operates in an unlicensed spectrum and is controlled by a base station. The processing circuitry and a receiver perform the monitoring of the downlink control channel based on a first timer and a second timer operated in parallel. The first timer is used to limit the maximum time the downlink control channel is to be monitored, by starting the first timer at the beginning of the monitoring and stopping the monitoring upon expiry of the first timer. The second timer is used to stop the monitoring earlier than the first timer depending on the channel occupation status of the unlicensed spectrum by the base station.

Abstract: Provided is a user equipment (UE), a scheduling node, and communication methods for UE and, respectively, scheduling node. The UE comprises a transceiver which, in operation, receives a configuration of a PoSS (power saving signal) time window for monitoring a PoSS and preceding a DRX (discontinuous reception) ON period for monitoring a PDCCH (physical downlink control channel), wherein the PoSS indicates whether or not the UE starts monitoring for the PDCCH in the DRX ON period and circuitry which, in operation, determines, based on the configuration, the PoSS time window, and controls the transceiver to perform monitoring for the PoSS within the PoSS time window.

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 communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.

Abstract: Provided is a terminal which can suitably apply precoding to a PDCCH. In the terminal (100), when a first CC is notified of scheduling information for each of a first component carrier (CC) and a second CC, a restriction determination unit (105) determines, on the basis of a subcarrier interval of the CC to be scheduled by means of the scheduling information among the first CC and the second CC, the maximum number of blind decodings when the scheduling information is blind-decoded. An extraction unit (102) performs the blind decoding on the basis of the maximum number of blind decodings and extracts the scheduling information.
