Apparatus, methods, and computer-readable media for facilitating a HARQ flush indicator for transmissions are disclosed herein. An example method for wireless communication at a first sidelink device includes transmitting a sidelink transmission of one or more CBs using code block groups, each code block group including one or more CBs of the sidelink transmission. The example method also includes receiving negative feedback for at least one CB of the sidelink transmission. Additionally, the example method includes retransmitting the at least one CB. The example method also includes transmitting an FI indicating to avoid combining a prior sidelink transmission of the at least one CB with a retransmission of the at least one CB.

Wireless communications are described. A wireless device may be configured to transmit a first signal via a first cell group that may overlap in time with a second signal via a second cell group. The wireless device may adjust a signal transmission power of at least one of the first signal or the second signal. Additionally or alternatively, the wireless device may drop at least one of the first signal or the second signal. Adjusting and/or dropping at least one of the first signal or the second signal may be based on the overlap in time of these signals satisfying a duration threshold and a total power to transmit the first signal and the second signal exceeding a power threshold.

A wireless communication device that communicates with a plurality of slave units, including: a transmitter that transmits a data transmission instruction including a first identification information of a single slave unit among the plurality of slave units; a receiver that receives data corresponding to the data transmission instruction from the single slave unit; wherein the transmitter transmits to the plurality of slave units acknowledgment data which has incorporated second identification information into an acknowledgment to the data received from the single slave unit, the second identification information indicating another slave unit which transmits data corresponding to a next data transmission instruction to the wireless communication device.

A method and an apparatus for uplink transmission in a communication system. An operation method of a terminal includes: receiving, from a base station, first SFI information indicating n flexible symbol(s); receiving, from the base station, second SFI information re-indicating m symbol(s) of the n flexible symbol(s) as uplink (UL) symbol(s); and transmitting an SRS to the base station through the m symbol(s) re-indicated as a UL symbol among the n flexible symbol(s) indicated as a flexible symbol. Therefore, performance of the communication system can be improved.

There is disclosed a method of operating a receiving radio node in a wireless communication network. The method includes communicating utilising data signaling based on a received control information message, the control information message scheduling multiple occurrences of data signaling, wherein communicating is based on extracting a code block group (CBG) setup for communicating based on the received control information message and/or a CBG configuration. The disclosure also pertains to related devices and methods.

For multiplexing control information in a physical uplink data channel, a user equipment (UE) includes receiving a configuration for a first set of values and receiving a downlink control information (DCI) format scheduling a transmission of a physical uplink shared data channel (PUSCH) over a set of resource elements (REs) and including a field providing an index. The method further includes determining a first value from the first set of values based on the index, determining a first subset of REs from the set of REs, for multiplexing first uplink control information (UCI), based on the first value, and transmitting the first UCI in the PUSCH.

Embodiments described herein relate to downlink (DL) control channel signaling for an aperiodic channel state information (A-CSI) trigger. In one example, a user equipment (UE) communicates with a network to receive first configuration signaling to identify a first downlink control information (DCI) in a physical downlink control channel (PDCCH). The UE also receives, from the network, the first DCI. The first DCI is appended with cyclic redundancy check (CRC) bits that are scrambled by a common radio network temporary identifier (RNTI) and is to indicate an aperiodic channel state information (A-CSI) trigger. Next, the UE receives, from the network, channel state information (CSI) reference signals in one or more occasions that follow an occasion in which the first DCI is received and generates and transmits a CSI report in a physical uplink control channel (PUCCH) based on the CSI reference signals.

A method of wireless communication by a transmitting sidelink user equipment (UE) determines at least one quasi-co-location (QCL) relationship between antenna ports of the transmitting sidelink UE. The QCL relationship corresponds to carrier frequency offset (CFO), average delay, delay spread, Doppler shift, and/or Doppler spread across the antenna ports of the transmitting sidelink UE. Each port maps to a different transmission and reception point (TRP). The method also indicates the QCL relationship(s) to a receiving sidelink UE. A method of wireless communication by a receiving sidelink UE receives a message from TRPs of a transmitting sidelink UE. The message indicates a QCL assumption for the TRPs. The method also individually measures reference signals received from each transmission port of the TRPs. The method may also determine whether signaling from the TRPs satisfies all conditions for the QCL assumption, and report to the transmitting sidelink UE a result of the determining.

Example channel state information (CSI) transmitting methods and apparatus are described. The CSI is a part of uplink control information (UCI) and it includes a first quantity of bits. One example method includes determining a threshold code rate according to a modulation and coding scheme (MCS) index when the CSI is to be transmitted on a physical uplink shared channel (PUSCH) without uplink data. A second quantity of bits is determined according to the threshold code rate and the first quantity of bits, where the second quantity of bits is less than or equal to the first quantity of bits. The second quantity of bits of the CSI is transmitted on the PUSCH.

The present disclosure provides a method for transmitting uplink control information, a method for receiving uplink control information, a method for configuring a downlink HARQ feedback function, a terminal and a base station. The method for transmitting uplink control information comprises: transmitting uplink control information to a base station, wherein the uplink control information comprises at least one of decoding statistical information for downlink transmission, suggestion information for downlink scheduling, or channel quality related information.
