Embodiments of the present disclosure provide a method and system for adjusting a physical uplink control channel (PUCCH) format in a wireless communication network. In particular, the method is implemented for adjusting a PUCCH format in an uplink transmission from a terminal device to a network device in a wireless communication network. The method comprises: using a first PUCCH format having a first duration for a service between the terminal device and the network device; and using (804) a second PUCCH format having a second and different duration for the service of the terminal device responsive to a determination that the first PUCCH format is in need of change based on one or more events.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a size of an uplink control information (UCI) part exceeds a UCI part payload size limit, wherein the UCI part includes hybrid automatic repeat request acknowledgment information (HARQ-ACK), and may selectively transmit the UCI part based at least in part on determining that the size of the UCI part exceeds the UCI part payload size limit. Numerous other aspects are provided.

A method and apparatus for dynamic acknowledgement repetition for a downlink medium access control packet data unit transmission ‘MAC PDU’ requiring multiple acknowledgements, the method having the steps of: receiving the downlink MAC PDU requiring multiple acknowledgements; and utilizing a differentiating factor and acknowledgement scheme, sending the multiple acknowledgements.

Examples disclosed herein include a method performed by a wireless device for transmitting a Packet Data Convergence Protocol (PDCP) protocol data unit (PDU). The method comprises selecting one or both of a first path and a second path for transmitting the PDU to a destination based on a comparison of a first delay on the first path and a second delay on the second path, wherein the first delay includes a queueing delay and/or a processing delay on the first path, and/or the second delay includes a queueing delay and/or a processing delay on the second path. If both the first path and the second path are selected, the method comprises using carrier aggregation (CA) or dual connectivity (DC) to send the PDU to the destination on the first path using a first carrier and sending a duplicate of the PDU to the destination on the second path using a second carrier.

Provided is a wireless communication device including a reception controller that controls reception of a plurality of data frames provided by another device through repeated transmission, the plurality of data frames including the same data. The wireless communication device further includes a transmission controller that controls transmission of a confirmation response signal to the other device on a per-data frame basis, on a per-repeated transmission basis, or both.

Methods and apparatuses for acknowledgement information with reduced redundancies. A method for a user equipment (UE) to provide a number of first hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits includes determining a number of second HARQ-ACK information bits based on a HARQ-ACK codebook. The number of second HARQ-ACK information bits is larger than a first predetermined number and smaller than a second predetermined number. The first and second predetermined numbers are consecutive in a set of predetermined numbers. The method further includes determining the number of first HARQ-ACK information bits by appending a number of bits to the number of second HARQ-ACK information bits. The number of bits is equal to a difference between the second predetermined number and the number of second HARQ-ACK information bits. The method further includes transmitting an uplink channel with the number of first HARQ-ACK information bits.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a feedback error configuration indicating an error threshold associated with a feedback error type of a set of feedback error types, and a time window for feedback error detection per frequency band combination. The UE may detect one or multiple feedback errors for the feedback error type within the time window, and determine that a number of the one or multiple feedback errors for the feedback error type exceeds the error threshold. The UE may transmit a feedback error indication based on the determination that the number of the detected one or multiple feedback errors exceeds the error threshold. The feedback error indication may include an indication of the one or multiple feedback errors and the feedback error type associated with the one or multiple feedback errors.

A radio communication apparatus comprises a spreading unit and a transmitting unit. The spreading unit spreads an ACK/NACK signal or a CQI signal with a sequence defined by one of a plurality of cyclic shift values. The transmitting unit transmits the ACK/NACK signal or the CQI signal. In each symbol that forms the ACK/NACK signal or the CQI signal, the spreading unit uses one of first cyclic shift values, which form a portion of the plurality of the cyclic shift values and which are adjacent to each other, for the ACK/NACK signal, and uses one of second cyclic shift values, which are not within the portion of the plurality of the cyclic shift values, for the CQI signal. At least one cyclic shift value that is cyclically subsequent to the first cyclic shift values or the second cyclic shift values is not used for either the ACK/NACK signal or the CQI signal.

Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor synchronization signal resources, each synchronization signal resources associated with a beam, and may select a preferred beam based on the monitoring. The UE may transmit an uplink random access message (e.g., message 3 of a four-step random access message, message A of a two-step random access procedure, or a negative acknowledgement (NACK) message requesting retransmission of a random access message) including beam information (e.g., one or more beam indices, channel quality information, or channel state information) to a base station. In response, the base station may transmit a downlink random access message using a different beam (e.g., a new preferred beam). The UE may establish a connection with the base station based on the completed random access procedure.
