Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may use low latency communications to improve the throughput of a wireless link. To facilitate efficient low latency communication, the UE may send UE-initiated CSI reports in addition to periodic and base station-initiated reports. For example, the UE may, in various examples, send UE-initiated CSI reports using contention based spectrum, using a request-to-transmit, or using a CSI differential (i.e., an indicator of a change in channel conditions). The base station may schedule different UEs for uplink low latency communication by providing resources to each UE for CSI and scheduling requests (SRs) using coherent or non-coherent uplink transmissions. The CSI and SR may also be combined with uplink feedback.

A terminal according to one aspect of the present disclosure includes a receiving section that receives information indicating first priority of first uplink transmission and receives information indicating second priority of second uplink transmission, and a control section that controls, in a case where the first uplink transmission and the second uplink transmission overlap each other in time, the first uplink transmission and the second uplink transmission, based on at least one of a combination of the first priority and the second priority and a cell group of the first uplink transmission or the second uplink transmission. According to one aspect of the present disclosure, it is possible to appropriately control UL transmission even in a case where priority is configured for UL transmission.

An uplink channel resource indication method, an uplink channel resource determination method, a base station, a terminal and a medium are pr. The uplink channel resource indication method includes: indicating frequency domain resource information corresponding to N subbands contained in a current carrier to a UE through high-layer signaling, where N>1; and indicating one or more subbands for uplink data transmission to the UE through downlink control information, so that the UE uses a frequency domain resource corresponding to the one or more subbands for uplink data transmission to transmit uplink data based on frequency domain resource information corresponding to the one or more subbands for uplink data transmission. Resource utilization and performance of a NR network may be improved.

A method of operating a wireless communication system is disclosed (FIG. 6). The method includes receiving a virtual cell identification (VCID) parameter (600) from a remote transmitter. A base sequence index (BSI) and a cyclic shift hopping (CSH) parameter (604,606) are determined in response to the VCID. A pseudo-random sequence is selected in response to the BSI and CSH (610,612). A reference signal is generated using the selected pseudo-random sequence (614).

A method of a terminal may comprise: receiving, from a base station, DCI including a first field indicating HARQ-ACK retransmission and a second field indicating a priority; identifying first HARQ-ACK information having a priority identical to the priority indicated by the second field; and transmitting, to the base station, a first HARQ-ACK codebook including the first HARQ-ACK information based on the indication of the first field.

Methods and apparatuses are provided in which it is determined to transmit a physical uplink control channel (PUCCH) with a positive scheduling request (SR) and one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits in a PUCCH resource of a PUCCH format 0. A value mcs for a cyclic shift for the PUCCH format 0 is identified based on the positive SR and the one or more HARQ-ACK information bits. The positive SR and the one or more HARQ-ACK information bits are transmitted to the base station in the PUCCH resource of the PUCCH format 0, based on the value mcs.

A method for transmitting information, includes: transmitting on one carrier wave according to at least one of a preset transmission mode and a transmission mode indicated by a base station eNB when agreed transmission time of two or more physical uplink shared channels PUSCH overlaps.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides a method for processing uplink control information (UCI) and a terminal. The method for processing UCI includes: determining the UCI which overlaps with a Physical Uplink Shared Channel (PUSCH) resource in time domain according to the PUSCH resource; determining whether to transmit the UCI, and performing corresponding processing based on a determination result. The present disclosure realizes effective transmission of UCI to be transmitted, and improves transmission efficiency.

A method and apparatus for sending uplink control information by a multi-mode wireless transmit/receive unit (WTRU) capable of operating on multiple component carriers of a plurality of radio access technologies (RATs) for multi-RAT operation are disclosed. The WTRU may generate uplink control information (UCI) pertaining to a first RAT and a second RAT, wherein the UCI may include a first plurality of hybrid automatic repeat request acknowledgements (HARQ-ACKs) pertaining to a plurality of downlink (DL) transmissions of the first RAT and a second plurality of HARQ-ACKs pertaining to a plurality of DL transmissions of the second RAT. The WTRU may multiplex at least part of the generated UCI pertaining to the first RAT and at least part of the generated UCI pertaining to the second RAT onto a physical channel on a component carrier of the second RAT.

A wireless device receives a downlink control information (DCI) comprising a first field indicating a transition of a cell to a dormant state and a second field indicating a hybrid automatic repeat request (HARQ) feedback timing. The wireless device transmits, in response to the DCI indicating the transition and via a physical uplink control channel resource, a positive acknowledgement of a reception of the DCI at a time interval based on the HARQ feedback timing.
