Abstract: The invention relates to transmission and reception of data in a wireless communication system. In particular, the predetermined number of repetitions of the same data portion is transmitted over the wireless interface. The receiving device receives the repetitions, attempts their decoding and checks whether the decoding was successful. If the decoding was successful after the predetermined number of repetitions or less, a positive acknowledgement is generated. In addition, a feedback including a bundle size information is generated and transmitted. The bundle size information includes a number of repetitions, smaller or equal to the predetermined number, after which the decoding was successful. The feedback is transmitted to the data transmitting device which may adapt the predetermined number of repetitions accordingly. The invention enables efficient control of the number of repetitions applied which is particularly advantageous for coverage enhancement purposes.

Abstract: A PUCCH resource collision between a normal mode terminal and MTC coverage enhancement mode terminal is avoided. A terminal includes a receiving section that receives control information indicating assignment of downlink data, and the downlink data; and a transmitting section that transmits a response signal using a resource in a first resource group when the terminal is a first terminal to which repetition transmission is applied, and that transmits the response signal using a resource in a second resource group that is different from the first resource group, when the terminal is a second terminal to which the repetition transmission is not applied.

Abstract: A response signal in each subframe is multiplied by a corresponding one of components forming one of a plurality of first sequences orthogonal to each other. The response signal is also multiplied by a second sequence defined by one of a plurality of cyclic shift indexes and one of a plurality of third sequences orthogonal to each other. Among a plurality of resources, a resource associated with one of at least two first sequences of the plurality of first sequences is different from a resource associated with another one of the at least two first sequences. Each of the plurality of resources is constituted by one of the plurality of cyclic shift indexes and one of the plurality of third sequences.

Abstract: The present disclosure relates to a user equipment, a base station, and uplink transmission and reception methods. The user equipment comprises a transceiver which, in operation, receives an indication indicating a priority level to be enforced, and circuitry which, in operation, compares a priority level of a first uplink transmission with the indicated priority level to be enforced, the first uplink transmission being granted to the UE prior to scheduling of a second uplink transmission allocated to resources overlapping with resources allocated to the first uplink transmission, wherein the transceiver, in operation, performs the first uplink transmission based on a result of the comparison.

Abstract: A user equipment (UE) receives a physical uplink shared channel (PUSCH) config information element (IE) in form of radio resource control (RRC) signaling; 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, each with a value indicating a PUSCH mapping type, a value K2 indicating a slot offsets, and a value SLIV indicating a start and length indicator value; and receives downlink control information (DCI) in form of medium access control (MAC) 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 UE determines allocated resources for an initial PUSCH transmission and allocated resources for at least one repetition thereof, and performs a PUSCH transmission using the respectively determined allocated resources.
