Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a single downlink control information (DCI) message that schedules communications on multiple cells, wherein the single DCI message indicates multiple time domain resource assignments (TDRAs) corresponding to the multiple cells, wherein each of the multiple TDRAs corresponds to a different scheduled communication; and communicate using the multiple TDRAs corresponding to the multiple cells, wherein the communicating comprises: transmitting the communications using the multiple TDRAs corresponding to the multiple cells, or receiving the communications using the multiple TDRAs corresponding to the multiple cells. Numerous other aspects are provided.

A method for transmitting acknowledgement/negative-acknowledgement (ACK/NACK) information of a user equipment (UE) configured with two serving cells including a first serving cell and a second serving cell, the method including receiving two transport blocks (TBs) through a downlink subframe of the first serving cell, receiving one TB through a downlink subframe of the second serving cell and transmitting ACK/NACK information informing ACK/NACKs for the two TBs and the one TB through an uplink subframe of the first serving cell, wherein the ACK/NACK information informs the ACK/NACKs for the two TBs and the one TB by a combination of one resource selected from a plurality of candidate resources and two bits transmitted through the one resource.

Arrangement for switching between an active bandwidth part and the target bandwidth part are disclosed. A method includes selecting one or more resource blocks comprised in the target bandwidth part for a transmission or reception between the wireless device and the network node. The selected resource blocks to be used in the target bandwidth part are indicated in a resource allocation field of a downlink control channel information in the active bandwidth part. The allocation field includes information bits and the resource allocation field in the active bandwidth part and the information bits are configured based on a target bandwidth part resource allocation type. The target bandwidth part resource allocation type indicates whether the information bits have a bitmap corresponding to one or more resource block groups or an integer value corresponding to a starting resource block and a length of the allocation in resource blocks.

DCI can include scheduling information for a physical channel carrying a TB and information of a plurality of available symbols within the plurality of allocated symbols. The scheduling information can include information of a plurality of allocated symbols for the physical channel. The physical channel can include a plurality of repetitions of the TB and can span at least one slot. Each of the plurality of repetitions can be within a slot of the at least one slot. At least one repetition of the plurality of the repetitions can have a different duration than another repetition. A repetition duration of each of the plurality of repetitions can be based on the plurality of available symbols for the physical channel.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink data transmission scheduled for transmission by the UE in a first transmission time interval overlaps with multiple uplink control transmissions also scheduled for transmission by the UE during corresponding second transmission time intervals that are shorter in duration than the first transmission time interval. The UE may determine that the multiple uplink control transmissions satisfy a scheduling constraint that is based at least in part on an uplink control transmission type of the multiple uplink control transmissions that overlap with the uplink data transmission. The UE may transmit the uplink data transmission and the multiple uplink control transmissions based at least in part on the scheduling constraint being satisfied.

Data channel sending and receiving methods, and an apparatus are disclosed. The network device sends indication information to the terminal, where the indication information indicates that the terminal needs to detect data channel puncturing information. The network device sends the data channel puncturing information to the terminal. The network device sends a data channel to the terminal, where the data channel is punctured at a resource location.

Systems and methods for transmitting uplink control information, for example ACK/NACK, while in RRC_inactive state, are provided. Uplink control information is transmitted while in RRC_INACTIVE state by transmitting a sequence from a set of possible sequences to convey the uplink control information, the transmitted sequence associated with a value of the uplink control information. The sequence is asynchronously transmitted. Signalling may be used to configure a transmission resource within which to transmit the sequence, wherein the transmission resource has a time duration that is longer than a time duration to transmit the sequence. This has the effect of introducing a gap following sequence transmission that can ensure the sequence transmission does not interfere with a data transmission.

A terminal is disclosed including a transmitter that transmits uplink control information and uplink data using an uplink shared channel; and a processor that, if frequency hopping is applied to the uplink shared channel, determines a mapping position for the uplink control information for each hop of the frequency hopping. In other aspects, a radio communication method for a terminal is also disclosed.

The present invention is designed so that, when a CP-OFDM waveform is supported in the UL in addition to DFT-spreading OFDM waveform, transmission of UCI can still be controlled adequately. According to the present invention, a user terminal has a transmission section that transmits uplink control information (UCI), and a control section that controls transmission of the UCI based on a waveform of an uplink (UL) data channel or based on indication information provided via higher layer signaling and/or downlink control information (DCI).

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of connected discontinuous reception (C-DRX) configurations. The set of C-DRX configurations may include a first C-DRX configuration and a second C-DRX configuration, where at least one C-DRX configuration in the set of C-DRX configurations is a UE-group common C-DRX configuration. The set of C-DRX configurations may correspond to a discontinuous transmission (DTX) cycle of the base station. The UE may select a C-DRX configuration from the set of C-DRX configurations based on receiving the control signaling from the base station. Accordingly, the UE may use the selected C-DRX configuration to communicate with the base station. The selected C-DRX configuration may enable the base station to operate with reduced power consumption and higher DTX efficiency, among other benefits.
