Abstract: HARQ-ACK is appropriately transmitted during enhanced carrier aggregation. A user terminal that can communicate with a radio base station by using six or more component carriers includes: a receiving section that receives scheduling information transmitted from the radio base station; a control section that determines based on the scheduling information to apply spatial bundling of a transmission acknowledgement signal only to a component carrier that the spatial bundling is applicable to; and a transmission section that transmits the transmission acknowledgement signal by using a PUCCH format 3.

Abstract: A method is provided in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node establishes that a number of data units that has been transmitted by the sending node are missing. The receiving node sends a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units. The omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node.

Abstract: A method of a user equipment (UE) for constructing a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook. The method comprises receiving physical downlink control channels (PDCCHs) that convey respective downlink control information (DCI) formats, wherein each DCI format includes a counter field and a slot offset field, receiving physical downlink data channels (PDSCHs) that convey data transport blocks, detecting the DCI formats configuring the received PDSCHs, determining locations for HARQ-ACK bits in a HARQ-ACK codebook based on a value of the slot offset field and a value of the counter field in each detected DCI format, determining a time unit for transmission of the HARQ-ACK codebook based on a value of the slot offset field in each detected DCI format, and transmitting the HARQ-ACK codebook.

Abstract: A method for a wireless communications system is disclosed. In one example, user equipment (UE) maintains at least one serving beam, and uses a serving beam to perform an uplink (UL) transmission of data. The data is stored in an uplink hybrid automatic repeat request (UL HARQ) buffer. When there is a failure to track the serving beam, a beam recovery procedure is initialized. After successful completion of the beam recovery procedure, the UE retransmits the data stored in the UL HARQ buffer. The UE prevents the data from being flushed from the UL HARQ buffer when the failure to track the serving beam occurs, so that the data can be retransmitted.
