摘要:
Uplink communication is efficiently performed in non-allocated frequencies. The terminal apparatus includes: a reception unit configured to receive downlink control information on a PDCCH; and a transmission unit configured to transmit a random access preamble. For a first frame structure type, the downlink control information is used to configure a subframe number of a first uplink subframe in which transmission of the random access preamble is allowed. For a second frame structure type, the downlink control information is used to configure a subframe number of a second uplink subframe in which transmission of the random access preamble is allowed and a symbol number of an uplink symbol in the second uplink subframe.

There is provided a terminal apparatus configured to communicate with a base station apparatus. The terminal apparatus is configured to: receive information indicating a subframe of a first subframe set and a subframe of a second subframe set by using a higher layer signaling. The terminal apparatus is configured to, in a case that a power headroom for a predetermined subframe for a predetermined serving cell is calculated: calculate the power headroom based on a reference format by using a first set of parameters in a case that transmission in a physical uplink shared channel is not performed in the predetermined subframe for the predetermined serving cell, and the predetermined subframe belongs to the first subframe set; and calculate the power headroom based on the reference format by using a second set of parameters in a case that the transmission in the physical uplink shared channel is not performed in the predetermined subframe for the predetermined serving cell, and the predetermined subframe belongs to the second subframe set.

A terminal device and a base station device can efficiently communicate with each other by using a downlink channel. The terminal device monitors, in a subframe k, a first set S k (L) of first PDCCH candidates and a second set S k (L) of second PDCCH candidates. A first number M c (L) of first PDCCH candidates is given based on first α c and M (L) , and a second number M c (L) of second PDCCH candidates is given based on second α c and M (L) . A first CCE corresponding to an m-th first PDCCH candidate included in the first set S k (L) and a second CCE corresponding to an m-th second PDCCH candidate included in the second set are given by an expression below. N CCE,k is a total number of CCEs in the subframe k, and L is an aggregation level.

A terminal device and a base station device can efficiently communicate with each other by using a downlink channel. The terminal device monitors, in an EPDCCH-PRB-set p in a subframe k, a first set ES k (L) of first EPDCCH candidates and a second set ES k (L) of second EPDCCH candidates. A first number M p,c (L) of the first EPDCCH candidates is determined according to a first α p,c and M p (L) , and a second number M p,c (L) of the second EPDCCH candidates is determined according to a second α p,c and M p (L) . A first ECCE corresponding to an m th first EPDCCH candidate included in the first set ES k (L) and a second ECCE corresponding to an m th second EPDCCH candidate included in the second set are determined according to a first value. The first value is given by a following expression, where N ECCE,p,k is a total number of ECCEs included in the EPDCCH-PRB-set p in the subframe k.

Uplink data is transmitted efficiently. A terminal device includes: a reception unit configured to receive a parameter included in an RRC message; a higher layer processing unit configured to store an uplink grant as a configured uplink grant; and a transmission unit configured to transmit a MAC protocol data unit. In a case that the parameter is configured and an initial transmission based on the configured uplink grant is performed and that the MAC protocol data unit includes only a prescribed MAC control element, the MAC protocol data unit is not transmitted. The prescribed MAC control element includes a MAC control element for a padding BSR, and does not include a MAC control element for a regular BSR.

Aspects of the disclosure relate to a terminal device including a transmission unit configured to transmit a HARQ-ACK using a first PUCCH resource and a PUCCH format (3) with respect to PDSCH transmission on a secondary cell having a cell index less than or equal to a first predetermined value, and transmit a HARQ-ACK by using a second PUCCH resource and a PUCCH format (4) with respect to PDSCH transmission on a secondary cell having a cell index greater than the first predetermined value. The first predetermined value may be the value of a fourth cell index when arranging the values of the cell indices set by a base station device in ascending order.

摘要:
A reception unit is included that receives pieces of information for a cell group, which include information indicating an RNTI and information indicating a subframe for monitoring a physical downlink control channel with the RNTI, receives pieces of information for each of multiple cells in the cell group, which include information for determining an index of information indicating an UL-DL configuration for each of the multiple cells in the cell group, and monitors the PDCCH that is accompanied by the RNTI, on a common search space of one cell in the cell group, on the subframe for monitoring the PDCCH with the RNTI. The information indicating the UL-DL configuration for each of the multiple cells in the cell group is transmitted on the PDCCH with the RNTI.
