Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a source device may determine a transmit power level increase based at least in part on a failed transmission for a message having a deadline for reception at a target device. For example, in some aspects, the deadline for reception of the message may be based at least in part on a survival time for an application consuming a communication service associated with the message. The source device may transmit a next message using the transmit power level increase during the survival time and prior to the deadline for reception of the message at the target device. Numerous other aspects are provided.

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. Embodiments of the present invention provide a method for RACH re-attempt, a user equipment and a base station. The method comprises the steps of: by a base station, determining system configuration information and transmitting the system configuration information to a user equipment; and then, by the user equipment, transmitting a preamble sequence to perform random access, and if the random access is failed, performing RACH attempt according to the received RACH re-attempt configuration information to perform random access until a preset decision condition is satisfied. The embodiment of the present invention is used for RACH re-attempt when random access fails.

A method in a transmitter comprises transmitting a first data block to a first user, using an index modulation scheme and using SSD for transmitting the first data block. In some embodiments, the index modulation scheme is index-modulated OFDM and the indices comprise subcarrier indices. The method further comprises determining that a retransmission of the first data block to the first user is needed, and rearranging a bit mapping of bits in the first data block to indices used in the index modulation scheme, compared to a bit mapping previously used for transmitting the first data block to the first user using the index modulation scheme. The method further comprises retransmitting the second data block to the first user, where this retransmitting comprises using the index modulation scheme with the rearranged bit mapping and using SSD.

Methods, systems, and devices for wireless communications are described. In some examples, a base station may recover a UE from a Msg3 failure during an RA procedure. During the RA procedure, the base station may transmit a RAR message to the UE and in response to the RAR message the UE may transmit an uplink message (e.g., Msg3) to the base station over a first resource indicated in the RAR message. If the base station fails to decode or receive the uplink message over the first resource, the base station may transmit a grant to the UE indicating a second resource for retransmitting the uplink message and the UE may retransmit uplink message to the base station according to the grant.

An information handling system includes a wireless local area network (WLAN) radio and a system embedded controller (EC). An antenna controller may determine an antenna type from a group consisting of a passive antenna and an active antenna, map a platform-unique subsystem identifier in accordance with the antenna type, configure a heartbeat message path to the system EC based on the antenna type, and control a WLAN radio transmit power level based on a heartbeat status.

Disclosed are a method and an apparatus by which user equipment controls transmission power of a sidelink signal in a wireless communication system that supports a sidelink, according to various embodiments. Disclosed are a method and an apparatus by which user equipment controls transmission power of a sidelink signal in a wireless communication system that supports a sidelink, wherein the method comprises the steps of: calculating required power for each antenna unit included in a plurality of antenna units to which the sidelink signal is transmitted; determining reference transmission power on the basis of the required power calculated for the plurality of antenna units; and allocating transmission power for the plurality of antenna units on the basis of the reference transmission power.

This disclosure provides systems, methods, and apparatus for wireless communications that support fast user equipment (UE) handover between base stations. A UE may receive, from a source base station, a configuration for reference signal transmission at a set of uplink transmit power levels. The UE may transmit multiple uplink reference signal repetitions based on the configuration. The source base station may transmit a request message to a target base station to measure the multiple uplink reference signal repetitions. The target base station may select an uplink reference signal and measure a transmit power correction. The target base station may transmit an indication to the source base station of the selection and transmit power correction. The source base station may evaluate the indications and select the target base station. The source base station may forward to the indicated contents, and the UE may switch and synchronize with the target base station.

Facilitating a transmission power dependent resource reservation protocol in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise defining, by a system comprising a memory and a processor, a resource reservation procedure that associates respective amounts of reserved resources available for the mobile device based on a transmission power level of the mobile device. The method also can comprise selecting, by the system, an amount of reserved resources from the respective amounts of reserved resources available based on the transmission power level of the mobile device.
