The present aspects relate to device-to-device (D2D) relaying in a wireless communication system. In an aspect, a remote user equipment (UE) may transmit, on at least one sidelink channel, a scheduling request to a relay UE connected with a network entity. The remote UE may further receive, on one or more sidelink channels, a scheduling indication including a resource grant from the relay UE in response to transmitting the scheduling request. In a further aspect, a relay UE may receive, on at least one sidelink channel, a scheduling request from a remote UE. The relay UE may further determine, a resource grant for the remote UE in response to receiving the scheduling request. The relay UE may further transmit, on one or more sidelink channels, a scheduling indication including the resource grant to the remote UE.

Methods, network nodes and wireless devices configured for resource allocation to a wireless device are disclosed. According to one aspect, a method includes selecting at least one of a common bandwidth scheme and a common power scheme. If the selected at least one scheme includes a common bandwidth scheme, a common bandwidth to be used by the wireless device for transmission of two data channels in two successive short transmission time intervals, sTTIs, that share a common demodulation reference signal, DMRS, is determined. An indication of the common bandwidth to the wireless device to enable the wireless device to set the bandwidth of the two data channels to a common bandwidth value is sent. If the selected at least one scheme includes a common power scheme, then a common power control command to control an output power to be set by the wireless device for two data channels in two successive sTTI, that share a common DMRS is determined. The common power control command to the wireless device to enable the wireless device to set the output power of the two data channels to a common power value is sent.

A method of a UE is provided. The method includes receiving, from a base station, first information of a first timer of a bandwidth part inactivity associated with a bandwidth part of a primary cell (PCell) and second information of a second timer of a bandwidth part inactivity associated with a bandwidth part of a secondary cell (SCell), identifying that a random access procedure is initiated on the PCell or the S cell, stopping the first timer, if running, in response to identifying that the random access procedure is initiated on the Pcell, and stopping the first timer and the second timer, if running, in response to identifying that the random access procedure is initiated on the SCell. The method relates to a communication method and system for converging a 5th-Generation communication system for supporting higher data rates beyond a 4th-Generation system with a technology for Internet of Things (IoT).

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-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. A method of a UE is provided. The method includes transmitting, to a base station, a random access preamble for initiating a random access procedure; receiving, from the base station, a random access response; transmitting, to a base station, a first message for requesting system information (SI); receiving, from the base station, physical downlink control channel (PDCCH) associated with a temporary cell radio network temporary identifier (TEMPORARY C-RNTI); identifying whether a contention resolution is successful; identifying whether a random access procedure is initiated for requesting the SI; and indicating a reception of an acknowledgement for requesting the SI to upper layer in response to identifying that the contention resolution is successful and the random access procedure is initiated for requesting the SI.
