摘要： Methods and apparatuses for retransmitting uplink control information. An apparatus comprising: a receiver that receives uplink control information (UCI) from a remote unit, wherein the UCI includes hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback corresponding to a plurality of downlink transmissions; a processor that decodes the UCI; and a transmitter that, in response to the UCI not being correctly decoded, transmits a first signaling to the remote unit, wherein the first signaling includes an indicator indicating that the UCI is not correctly decoded.

摘要： The present application is related to a method and apparatus for HARQ-ACK codebook determination. A method of receiving information according to one embodiment comprises receiving, from a base unit, a first signal for indicating a first parameter which is a quantity of transport blocks (TBs) in a downlink association set and receiving a second signal for indicating a second parameter which is a quantity of hybrid automatic repeat request acknowledgement (HARQ-ACK) bit fields in a HARQ-ACK codebook, determining a size of the HARQ-ACK codebook based on the first signal and the second signal, and transmitting the HARQ-ACK codebook to the base unit, wherein the HARQ-ACK codebook comprises a first part including K1 HARQ-ACK bits and a second part including K2 HARQ-ACK bit fields, wherein each bit in the first part corresponds to one TB in the downlink association set; and each HARQ-ACK bit field in the second part corresponds to one incorrectly decoded TB in the downlink association set. The present application reduces signaling overhead for a HARQ-ACK codebook and avoids misunderstanding between a base unit and a remote unit when determining a HARQ-ACK codebook.

摘要： The present application is related to a method and apparatus for determining a hybrid automatic repeat request-acknowledge (HARQ-ACK) codebook for carrier aggregation (CA). A method for determining a HARQ-ACK codebook for CA includes receiving a first control signal on a carrier within a carrier group in a slot, wherein the first control signal includes an indicator for indicating whether the carrier is a last scheduled carrier of the carrier group for downlink transmissions. The method further includes transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook corresponding to the downlink transmissions in the slot for the carrier group, wherein, based on the first control signal, one or more HARQ-ACK bits for the last scheduled carrier are arranged at the end of the HARQ-ACK codebook. The present application reduces signaling overhead for a HARQ-ACK codebook and avoids misunderstanding between a base unit and a remote unit when determining the HARQ-ACK codebook for CA.

摘要： Apparatus and methods of Channel Status Information (CSI) acquisition on sidelink are disclosed. The apparatus includes: a transmitter that transmits a reference signal to a device on a sidelink (SL) transmission; a receiver that receives a channel quality report from the device; and a processor that controls the transmitter and the receiver, and decodes the channel quality report to obtain a channel quality; wherein the processor is configurable to support one or a combination selected from a group consisting of: a reporting activation scheme where an SL Channel Status Information (CSI) reporting activation indicator is configured; and a measurement triggering scheme where the transmitter initiates transmission of the reference signal upon satisfying a triggering condition.

摘要： Apparatuses, methods, and systems are disclosed for determining channel statistics for clear channel assessments. One method (900) includes determining (902), by an apparatus (102), channel statistics corresponding to a plurality of listen-before-talk channel access types, a plurality of channel access priorities, a plurality of frequency ranges, or some combination thereof. The channel statistics indicate whether clear channel assessments for transmission on a shared resource are successful. The method (900) includes transmitting (904) information corresponding to the channel statistics to a network device.
