A CSI transmission method, a method for triggering CSI transmission, and a related device are provided. The CSI transmission method includes: controlling transmission of channel state information CSI based on a data type of the CSI, where the data type includes a type that requires a hybrid automatic repeat request HARQ feedback or a type that requires no HARQ feedback.

Embodiments of the present disclosure provide a method for transmitting uplink control information. The method includes: a User Equipment (UE) receives Uplink Control Information UCI configuration information, wherein the UCI configuration information includes information for determining a periodicity, an offset and a Physical Uplink Control Channel PUCCH for Periodic-Channel State Information P-CSI to be report in one subframe and configuration information for transmission of Hybrid Automatic Retransmission reQuest-Acknowledgement HARQ-ACK; processes one or more kinds of UCI in the subframe, and transmits the UCI on resources using a PUCCH format. According to the method of the present disclosure, the transmit power for transmitting the UCI on the channel using the PUCCH format is optimized. During the transmission of the P-CSI, the PUCCH resource most preferable for the transmission of the P-CSI is determined. The uplink resource utilization ratio is increased.

Methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to triggering feedback of channel state information. In one exemplary aspect, a method for wireless communication is disclosed. The method includes receiving, by a terminal, a first message from a wireless communication node. The method also includes transmitting, by the terminal, a feedback message to the wireless communication node via a first channel responsive to receiving the first message from the wireless communication node, the feedback message including at least one set of channel status information.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE measures a first set of reference signals to determine a first channel state of a first channel between a first TRP and the UE. The UE measures interference received at the UE. The UE sends a first CSI report generated corresponding to the first channel state. The UE sends a second CSI report generated corresponding to the interference.

A method and an apparatus for feeding back channel state information (CSI) of user equipment (UE) in a communication system are disclosed. The method comprises the steps of: receiving, from a base station, configuration information related to a plurality of CSI reports; identifying the setting of the plurality of CSI reports corresponding to a plurality of measurement resources, on the basis of the configuration information; generating a first CSI report corresponding to a first measurement resource and a second CSI report corresponding to a second measurement resource when the plurality of CSI reports are set; and transmitting the first CSI report and the second CSI report to the base station.

A user equipment (UE) generates a positioning state information (PSI) report to be transmitted in a lower layer channel, e.g., in the Physical or Medium Access Control channel, to a network entity to reduce latency. The PSI reports may be generated based on information from uplink (UL), downlink (DL) or UL and DL positioning measurements performed by the UE. When multiple PSI reports collide, e.g., to be transmitted simultaneously, or when a PSI report and a Channel State Information (CSI) report collide, prioritization of the reports is performed using priority rules based at least in part on positioning related content of the PSI reports. The PSI report or CSI report with the highest priority is transmitted to the network entity on the lower layer channel, and lower priority reports may be omitted. A network entity may receive and process the PSI report based on the priority based rules.

An operation method of a first terminal in a communication system is provided. The method includes transmitting first SCI to a second terminal, the first SCI including one or more information elements among information indicating time resource(s) for sidelink communication, information indicating frequency resource(s) for the sidelink communication, information indicating a periodicity of physical resources for the sidelink communication, and information indicating an MCS for the sidelink communication. Second SCI is transmitted to the second terminal, the second SCI including information for an HARQ feedback operation and information indicating an NDI. The method further includes performing the sidelink communication with the second terminal based on the first SCI and the second SCI associated with the first SCI.

In the field of wireless communication technologies, method and apparatus for determining a transport block size (TBS) of a data channel are provided. In a communication network, a terminal device receives control information from a network device. The control information includes modulation indication information and resource information of the data channel. The terminal device determines a modulation order and a code rate according to the modulation indication information, and determines number of time-frequency resources according to the resource indication information of the data channel. The terminal device determines the TBS according to the modulation order, the code rate, and the number of time-frequency resources. Based on the determined TBS, the terminal device decodes the data channel carried on the time-frequency resources or sends the data channel on the time-frequency resources.

Embodiments of the present disclosure relate to methods, devices, and computer readable medium for uplink signal transmitting and receiving. A method comprises: receiving a first downlink signal from a first transmission/reception point (TRP); receiving a second downlink signal from a second TRP; and transmitting an uplink control signal to at least one of the first and second TRPs, the uplink control signal comprising first control information associated with the first downlink signal and second control information associated with the second downlink signal, and the first control information and the second control information being included in the uplink control signal in an order determined by an identification related to reference signals associated with the first downlink signal and the second downlink signal. Embodiments of the present disclosure may avoid ambiguity in uplink control information bit ordering in uplink control signal transmission and reception.

A UE according to an embodiment of the present disclosure may receive information about a plurality of beta offset values for determining the number of REs for UCI to be transmitted on a PUSCH, receive DCI scheduling a first PUSCH, and transmit a first HARQ-ACK on the first PUSCH, and transmit the first PUSCH. The plurality of beta offset values may include first beta offset values for a case where the priority of the first HARQ-ACK is identical to the priority of the first PUSCH, and second beta offset values for a case where the priority of the first HARQ-ACK is different from the priority of the first PUSCH.
