The present disclosure may provide a feedback mechanism in which a feedback PDU may be transmitted by a UE with one or more modified transmission characteristics for both an activation and deactivation of the SPS grant. The feedback PDU transmitted with modified transmission characteristics may increase the reliability of the communication system and reduce the latency of the communication system, while also activating and/or deactivating SPS grants. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may generate a feedback PDU. In addition, the apparatus may modify a transmission characteristic associated with the feedback PDU. Furthermore, the apparatus may transmit, using the modified transmission characteristic, the feedback PDU to the base station.

A mobile station for use in a wireless network that operates according to the Long-Term Evolution Advanced (LTE-A) standard. The mobile station is operable to transmit an aperiodic sounding reference signal (SRS) to a base station in response to a triggering grant received from the base station. The bandwidth on which the mobile station transmits the aperiodic SRS depends on a type of the triggering grant. The type of the triggering grant is one of a downlink grant, an uplink multiple-input, multiple-output (MIMO) grant, and an uplink single-input, multiple-output (SIMO) grant.

An electronic device disclosed herein includes mechanisms for modeling and dynamically controlling transmission power of an electronic device. The electronic device determines a back-off function defining at least one transmission power adjustment that is effective to adjust a predicted average energy emanating from an electronic device over the future time interval to satisfy a power condition. Power of the electronic device is adjusted according to the back-off function responsive to satisfaction of a proximity condition.

Methods and apparatus are provided for transmission preemption and its indication. In one novel aspect, the UE receives a downlink resource assignment and determines whether an ultra-low latency (ULL) alert signal exists, wherein the ULL alert signal indicates a set of soft bits are overridden. The UE discards the set of soft bits from the overridden resources upon determining the ULL alert signal exists. In one embodiment, the ULL alert signal resides in the assignment subframe, and the overridden soft bits are in the assignment subframe. The alert timing for the ULL alert signal is preconfigured. In another embodiment, the ULL alert signal resides in a subframe that is right after the assignment subframe. The alert signal is enabled through an enabling of an enhanced mobile broadband and ULL service. The alter signal indicates a superset of the overridden soft bits or part of the overridden soft bits.

Provided is a terminal device that communicates with a base station apparatus using a first cell group and a second cell group. The terminal device includes a higher-layer processing unit that sets guarantee power in the first cell group and guarantee power in the second cell group. In a case where a radio link failure occurs in a serving cell belonging to the second cell group, the guarantee power in the first cell group and/or the guarantee power in the second cell group are changed.

Embodiments include systems and methods for managing radio frequency (RF) spectrum usage by a processor of a wireless network node. The processor may scan one or more frequencies to determine a spectrum usage. The processor may identify one or more high priority devices based on the scanning The processor may determine a maximum RF interference threshold of the one or more high priority devices based on the spectrum usage and the identification of the one or more high priority devices. The processor may calculate a transmit power for one or more wireless network nodes based on the determined maximum RF interference threshold, and the processor may transmit a signal at or below the calculated transmit power.

Embodiments of the present invention provide methods, computer program products, and systems. Embodiments of the present invention can be used to, in response to response to anticipating a maneuver to be performed by a vehicle, adjust one or more 5G dedicated traffic channels (DTCH) over a radio bearer network. Embodiments of the present invention can be used to revert the one or more adjusted 5G DTCH after the maneuver is performed by the vehicle.

The present invention relates to transmission power control for a device operating in a Wireless Local Area Network (WLAN) system, and a transmission and reception method and apparatus using the transmission power control. According to an aspect of the present invention, a method for transmitting an uplink frame to an Access Point (AP) by a Station (STA) in a WLAN system may include receiving first transmission power control information and second transmission power control information from the AP, if a type related to the uplink frame is a first type, determining a maximum transmission power based on the first transmission power control information, if the type related to the uplink frame is a second type, determining a maximum transmission power based on the second transmission power control information, and transmitting the uplink frame based on the determined maximum transmission power. The first type and the second type may correspond to different access schemes for uplink transmission.

The present invention provides a V2X operation method implemented by a V2X (vehicle-to-X) terminal in a wireless communication system, the method characterized by: receiving information which indicates that another communication is implemented on V2X resources; and transmitting a V2X message on the basis of the information, wherein a V2X terminal is a terminal having limited capability to detect the implementation of the other communication on the V2X resources.

Exemplary embodiments include methods performed by a radio access network node for power control of UE uplink (UL) transmissions that are associated with data services having different reliability requirements. Such methods include configuring the UE with a plurality of resources that can be allocated for UL transmissions based on one or more transmit power control (TPC) parameters. The resources include first resources associated with first parameter values and second resources associated with second parameter values, for the respective TPC parameters. The first parameter values provide increased UL transmission reliability versus the second parameter values. Such methods include transmitting, to a UE, a downlink control message comprising an indication that the first resources or the second resources are allocated for an UL transmission associated with a data service, and an indication of the first parameter values or the second parameter values to be used for power control of the UL transmission.
