In an audio apparatus including a first device and a second device that each receive the same audio data transmitted from a source device, a device having the worse reception environment of the audio data out of the first device and the second device, operates as a primary device that performs a retransmission request for the audio data to the source device, and a device having the better reception environment operates as a secondary device that performs the retransmission request for the audio data to the primary device.

A transmission or reception configuration method and a terminal are provided. The transmission or reception configuration method is performed by a terminal and includes: obtaining a transmission or reception configuration, where the transmission or reception configuration is used to indicate a first time domain range in which the terminal does not monitor a target object or a second time domain range in which the terminal monitors a target object.

A HARQ-ACK feedback mode determining method, a HARQ-ACK feedback mode configuration method, and a device are disclosed. The method includes: determining, according to a service type corresponding to a PDSCH, a HARQ-ACK feedback mode corresponding to the PDSCH; determining, according to a radio network temporary identifier RNTI of a PDSCH, a HARQ-ACK feedback mode corresponding to the PDSCH; or determining, according to downlink control information DO for scheduling a PDSCH, a HARQ-ACK feedback mode corresponding to the PDSCH.

A HARQ information transmission method and apparatus, to resolve a problem that HARQ information is not fed back in a timely manner. When a first device cannot successfully send first hybrid automatic repeat request (HARQ) information on a first time-frequency resource, or a second device cannot successfully receive the first HARQ information on the first time-frequency resource, the first device retransmits the first HARQ information on a second time-frequency resource for transmitting second HARQ information corresponding to second data. First data and the second data may be data with different priorities and/or in different groups. In this way, HARQ retransmission flexibility can be improved, and the first HARQ information is transmitted in a timelier manner, so that a data processing latency is reduced as much as possible.

A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.

Certain aspects of the present disclosure provide techniques for slot format for sidelink communication. A method that may be performed by a user equipment (UE) includes transmitting a data signal; refraining from transmitting during a gap portion occurring in time after the transmission of the data signal, wherein the gap portion has a duration less than or equal to a threshold; receiving a feedback signal after the gap portion, wherein the feedback signal comprises at least a signal and hybrid automatic retransmission request (HARQ) feedback for the data signal; receiving another signal; and adjusting a gain applied to the other signal based on the signal.

Example aspects include a method, apparatus, and computer-readable medium for wireless communication at a user equipment (UE) of a wireless communication network, comprising receiving, from a base station, configuration information indicating that physical downlink control channel (PDCCH) joint channel estimation (JCE) is enabled for a plurality of PDCCH monitoring occasions. The aspects further include receiving, from the base station, a plurality of PDCCH transmissions. At least one PDCCH transmission comprises a hybrid automatic repeat request (HARD) acknowledgement (ACK) request without a corresponding physical downlink shared channel (PDSCH) grant. Additionally, the aspects further include identifying a base offset according to the at least one PDCCH transmission. Additionally, the aspects further include selecting an additional offset according to a processing time capability of the UE. Additionally, the aspects further include transmitting, at a timing offset in relation to the plurality of PDCCH transmissions, a HARQ-ACK.

In an example, a User Equipment (UE) is configured with one or more first Physical Uplink Control Channel (PUCCH) resources on a primary cell (PCell) and configured with one or more second PUCCH resources on a secondary cell (SCell). The PCell and the SCell are associated with a PUCCH group. Before a first slot, the UE changes an active uplink (UL) bandwidth part (BWP) of a cell. The cell associated with the changing the active UL BWP is the PCell or the SCell. A first occasion of the PCell is before the changing the active UL BWP. A second occasion of the SCell is before the changing the active UL BWP. The first occasion and the second occasion are associated with the first slot. The UE determines whether or not to include Hybrid Automatic Repeat request (HARQ) information, associated with the second occasion, in a HARQ codebook based on whether or not the SCell, associated with transmitting the HARQ codebook, is the same as the cell associated with the changing the active UL BWP. The UE transmits, in the first slot and on the SCell, a PUCCH including the HARQ codebook.

An electronic device may receive aggregated data including a plurality of data blocks via a first link among a plurality of wireless communication links from a second electronic device connected to the electronic device via the plurality of wireless communication links, may transmit information indicating a failure to receive a target block among the plurality of data blocks to the second electronic device via a second link among the plurality of wireless communication links based on reception of the target block failing, and may receive the target block from the second electronic device via the second link.

Techniques for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling sidelink transmissions in one or more sets of multiple transmission time intervals (TTIs) over a shared spectrum. The UE may perform a listen-before-talk (LBT) for one or more of the TTIs in the one or more sets of multiple TTIs, and the UE may transmit, to a base station, an indication of results of the LBT performed for the one or more TTIs. Because the UE may provide the results of the LBT to the base station, the base station may be able to schedule sidelink transmissions from the UE based on the results of the LBT. As such, the UE may experience increased throughput in sidelink communications since the scheduling at the base station may be improved.
