Methods, systems, and devices for wireless communications are described. A base station communicates with a UE via transmission reception points (TRPs). A UE receives, from a base station, control signaling identifying a set of demodulation reference signal (DMRS) configurations. The UE receives, from the base station, control signaling activating a first DMRS configuration and a second DMRS configuration. The UE receives an indication for the UE to use a first transmission mode of a set of transmission modes to communicate with multiple TRPs of the base station. The UE selects at least one of the first DMRS configuration or the second DMRS configuration based on the indicated first transmission mode and a pre-defined logical association. The UE then receives DMRS signals from the TRPs of the base station, according to the selected at least one of the first DMRS configuration or the second DMRS configuration.

A method for controlling configuration of an air interface between an access node and at least one user equipment device (UE), where the air interface is divided over time into frames and the frames are further divided at least into subframes, where the air interface operates in accordance with a time-division-duplex (TDD) configuration that defines at least a number of uplink subframes per frame for communication over the air interface. An example method includes (i) detecting at least a threshold high rate of uplink voice muting on the air interface, and (ii) responsive to at least the detecting, changing the TDD configuration to increase the number of uplink subframes per frame over the air interface.

A method for transmitting uplink control information and an apparatus therefor are disclosed. In a method for transmitting uplink control information using a physical uplink shared channel (PUSCH) in a wireless communication system, the method is performed by a terminal and includes receiving downlink control information including an accumulated number of physical downlink shared channels (PDSCH) transmissions associated with a cell group configured for the terminal, coding the uplink control information using the accumulated number of PDSCH transmissions, and transmitting the coded uplink control information using the PUSCH.

Methods, systems, and devices for wireless communications are described. Techniques are described herein for cross component carrier (CC) shared channel repetition. The method for wireless communications may include identifying a set of CCs supported by a user equipment (UE) for communications with a base station. A UE may receive a downlink control message from the base station that schedules multiple repetitions of a transport block for the UE, where a first repetition of the multiple repetitions is scheduled on a first CC of the set of CCs and a second repetition of the multiple repetitions is scheduled on a second CC of the set of CCs. The method may also include transmitting or receiving the first repetition via the first CC and the second repetition via the second CC.

A communication management resource receives first input indicating a first time-division communication configuration associated with first wireless stations operated by a first wireless network service provider. The communication management resource receives second input indicating a second time-division communication configuration associated with second wireless stations such as operated by a second wireless network service provider. Based on spectral analysis of implementing the first time-division communication configuration and the second time-division communication configuration, the communication management resource controls implementation of time-division communication configurations by the first wireless stations and the second wireless stations.

The present disclosure relates to an electronic device, a method, and a storage medium for a wireless communication system. Various embodiments for setting guard periods for downlink-to-uplink switching are described. An embodiment relates to an electronic device for a base station used in a TDD communication system, and the electronic device comprises a processing circuit. The processing circuit is configured to: set a first guard period for downlink-to-uplink switching for a first terminal device in a first cell; and set a second guard period for downlink-to-uplink switching for a second terminal device in the first cell, wherein the second guard period for downlink-to-uplink switching is different from the first guard period for downlink-to-uplink switching. The first guard period for downlink-to-uplink switching is associated with a first resource, the second guard period for downlink-to-uplink switching is associated with a second resource, and the first resource and the second resource have orthogonality.

The present invention is designed to control transmission power properly even when communication is controlled based on shortened processing time. A user terminal communicates in a cell where a shortened TTI, having a transmission time interval (TTI) length shorter than 1 ms, is used, and/or in a cell where communication is controlled based on shortened processing time, which is shorter than in existing LTE systems, and this user terminal has a receiving section that receives a DL signal, a transmission section that transmits a UL signal in response to the DL signal, and a control section that controls transmission power of the UL signal based on a power control command contained in downlink control information transmitted in a predetermined transmission time interval in which the DL signal is transmitted, or in a transmission time interval located before the predetermined transmission time interval.

Embodiments are presented herein of apparatuses, systems, and methods for utilizing a flexible slot indicator in wireless communication. A base station (BS) may establish communication with a first user equipment device (UE). The BS may determine a transmission direction for each of a plurality of symbols included in one or more slots. The BS may transmit a slot format indicator (SFI) to the UE. The SFI may indicate the transmission direction for each of the plurality of symbols included in one or more slots. The BS and the UE may perform communication during the one or more slots according to the determined transmission direction.
