A method for feeding back a hybrid automatic repeat request acknowledgement (HARQ-ACK) and a terminal device. The method comprises: a terminal device receives a first physical channel transmitted by a network device using a first HARQ process, the first HARQ process corresponding to a disabled state; the terminal device generates a first HARQ-ACK codebook, the first HARQ-ACK codebook comprising a first HARQ-ACK feedback bit corresponding to the first physical channel, or, the first HARQ-ACK codebook comprising no first HARQ-ACK feedback bit corresponding to the first physical channel.

Provided are a channel transmission method, a terminal device and a network device. When an HARQ process is disabled, HARQ scheduling limitation is enhanced, thereby ensuring that the problem of disorder does not occur in a processing time sequence of a terminal device. The channel transmission method comprises: a terminal device transmitting a PUSCH by using a first uplink HARQ process, wherein the first uplink HARQ process corresponds to a first state, and a time interval between two adjacent PUSCH transmissions corresponding to the first uplink HARQ process is greater than or equal to a first duration.

Techniques are described for multiplexing non-acknowledgement (NACK) only physical uplink control channel (PUCCH) transmission that overlaps in time domain with another uplink control channel transmission. An example wireless communication method includes performing a first determination, by a communication node, whether a scheduling request (SR) transmission needs to be performed in a control channel; performing a second determination, by the communication node and in response to determining that the SR needs to be transmitted in the control channel, that a first resource for a non-acknowledgement (NACK) only transmission in the control channel overlaps in time domain with a second resource for the SR transmission; and transmitting, in response to the second determination, a sequence in the second resource in the control channel, where the sequence indicates the SR and a feedback message for the NACK only transmission.

An AP transmits a multi-user first downlink transmission to a plurality of client stations via a first WLAN communication channel having a first RF bandwidth. The AP generates a MAC data unit having a trigger frame configured to prompt an uplink multi-user transmission by the plurality of client stations, and transmits a second downlink transmission to the plurality of client stations via a second WLAN communication channel having a second RF bandwidth. The second downlink transmission includes the MAC data unit. The AP receives the uplink multi-user transmission from the plurality of client stations via the second WLAN communication channel, the uplink multi-user transmission including simultaneous transmissions from the plurality of client stations within the second WLAN communication channel that overlap in time with the multi-user first downlink transmission via the first WLAN communication channel.

Provided are a user equipment, base station and wireless communication methods related to multiplexing of UCI in PUSCH in NR. A user equipment comprises: circuitry operative to process UCI bits to be transmitted according to the comparison of the number M of UCI bits generated based on DL assignment(s) before an UL grant from a base station and the number N of UCI bits generated based on DL assignment(s) after the UL grant with the number P of UCI bits indicated in the UL grant and/or the maximum number Q of bits determined based on at least a configured coding rate, wherein each of M, N, P, Q is an integer equal to or larger than 0; and a transmitter operative to transmit the processed UCI bits in PUSCH at a TTI indicated in the UL grant to the base station.

An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for HARQ-ACK transmission in an NR network, the processing circuitry is to decode DCI received via a PDSCH. The DCI includes resource assignments, a set index, and a reset indicator for a set of PDSCHs. Downlink data associated with the set index and received via the set of PDSCHs using the resource assignments is decoded. A PUCCH is encoded for transmission to a base station to include a HARQ-ACK of the decoded downlink data associated with the set index. The PUCCH is encoded to further include a second HARQ-ACK for a prior PDSCH reception, when the prior PDSCH reception includes PDSCHs associated with the set index and the reset indicator matches a reset indicator of the prior PDSCH reception.

An operation method of a first communication node in a communication system may comprise receiving one or more transport blocks (TBs) from a second communication node based on transmission parameters in an aggregated transmission period #n; generating decoding results for the one or more TBs; generating information required for changing the transmission parameters based on the decoding results; and transmitting the required information to the second communication node, wherein n is a natural number.

Various solutions for supporting out-of-order hybrid automatic repeat request (HARQ) feedback with respect to user equipment and network apparatus in mobile communications are described. An apparatus may construct a first HARQ-ACK codebook corresponding to a first physical downlink shared channel (PDSCH) and construct a second HARQ-ACK codebook corresponding to a second PDSCH received later than the first PDSCH. The apparatus may activating an out-of-order HARQ transmission to transmit the first HARQ-ACK codebook and the second HARQ-ACK codebook in an event that the priorities associated with the codebooks are different.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive downlink data that is associated with triggering a feedback message; transmit, before receiving the feedback message for the downlink data at a component of the user equipment, a scheduling request to request an allocation of a set of resources for transmitting the feedback message; and transmit the feedback message in connection with the set of resources. Numerous other aspects are provided.
