Presented are systems, methods, apparatuses, or computer-readable media for multiple transmit reception point (TRP) transmission signaling. A wireless communication node may transmit, to a wireless communication device, a scheduling grant to schedule a plurality of transmission instances. The scheduling grant may include one or more transmission precoding matrix indicators (TPMIs) to indicate mappings between the plurality of transmission instances and a plurality of sounding reference signal (SRS) resource sets for uplink codebook based transmissions.

A method, device, and non-transitory computer-readable medium provide for scanning, by a device, a radio service area of a small cell radio access node to detect radio signals of one or more radio frequency (RF) bands, the radio signals including transmissions associated with one or more other small cell radio access nodes that are operating in a vicinity of the small cell radio access node, and the small radio access node being configured to alternately operate at multiple RF bands including the one or more RF bands; determining, by the device, a signal strength associated with each of the one or more RF bands; and dynamically optimizing, by device, operation of the small cell radio access node based on the signal strength associated with each of the one or more RF bands.

A terminal according to one aspect of the present disclosure includes a control section that, when spatial relation information for uplink transmission, of any one of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) scheduled by downlink control information (DCI) format 0_1 is not configured, determines a power control parameter for the uplink transmission to determine transmit power for the uplink transmission on the basis of the power control parameter, and a transmitting section that performs the uplink transmission by using the transmit power. According to one aspect of the present disclosure, it is possible to appropriately transmit UL transmission.

The present technology relates to a communication apparatus and a communication method that can improve a communication characteristic. The communication apparatus is a base station and includes a control section configured to determine, on the basis of first communication situation information regarding a communication situation of the base station and second communication situation information regarding a communication situation received from another base station, whether or not it is permissible to carry out control of a communication parameter in the base station, and determine, on the basis of the first communication situation information and the second communication situation information, whether or not it is permissible to transmit first control request information regarding a control request of a communication parameter in the other base station. The present technology can be applied, for example, to a wireless LAN system.

Embodiments of the present disclosure provide for mechanisms to enable full-power uplink transmission. Other embodiments may be described and claimed.

A UE may calculate an allocation of a transmission power for a first uplink transmission on a first uplink channel and at least one second uplink transmission on at least one second uplink channel, the transmission power being allocated in each symbol of a plurality of symbols in a slot. The UE may detect a transmission power change in the allocation of the transmission power in the slot for at least one of the first uplink transmission or the at least one second uplink transmission. The UE may determine whether to adjust the allocation of the transmission power for the at least one of the first uplink transmission or the at least one second uplink transmission to eliminate the transmission power change in the slot for the at least one of the first uplink transmission or the at least one second uplink transmission.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station via the transceiver, an indication to apply an amplitude drooping based at least in part on an uplink band being adjacent to a downlink band in a full-duplex operation. The UE may transmit, to the base station via the transceiver, an uplink transmission in the uplink band based at least in part on the amplitude drooping. Numerous other aspects are described.

Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for determining dynamic power sharing in a dual-uplink E-UTRA (Evolved Universal Terrestrial Radio Access)—new radio dual connectivity (EN-DC) network, and/or other new radio (NR) related networks. Various embodiments describe how to determine or configure respective transmission (TX) power levels for LTE and NR uplink signals in the dual-uplink EN-DC network. The NR uplink signal may or may not be transmitted based on a certain timeline threshold and/or power scaling threshold. Other embodiments may be described and claimed.

Methods and apparatuses for managing dual connectivity. A method for operating a UE includes receiving a configuration for dynamic power sharing (DPS) between transmissions on a master cell group (MCG) and transmissions on a secondary cell group (SCG) and determining a time offset as a function of sub-carrier spacing (SCS) configurations and of configurations for a PUSCH processing capability on the MCG and on the SCG. The method further includes determining a maximum power for a PUSCH transmission on the SCG, at a beginning of the PUSCH transmission on the SCG, when each of the transmissions on the MCG is scheduled by a downlink control information (DCI) format in a PDCCH reception that ends at least the time offset before the beginning of the PUSCH transmission on the SCG. The method further includes transmitting the transmissions on the MCG and the PUSCH transmission on the SCG.

In one aspect, a method performed by a user equipment (UE) in a communication network includes: receiving, in a downlink control information (DCI), from a base station, at least one indication, wherein each of the at least one indication indicates that uplink transmission by the UE should be cancelled or paused, and includes a combination of at least one bit representing at least one resource configuration for the uplink transmission; and cancelling or pausing respective uplink transmission in dependence on the at least one resource configuration represented by one of the at least one indication.
