The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring a Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource; receiving an Radio Resource Control (RRC) signaling indicating that the PUCCH resource is de-configured from the SCell, wherein the RRC signaling includes an indication which indicates whether the UE activates or deactivates the SCell from which PUCCH resource is de-configured; de-configuring the PUCCH resource from the SCell; and activating or de-activating the SCell according to the indication after the UE de-configures PUCCH from the SCell.

In a multi-carrier wireless system, potential problems from reconfiguring mobile station resources to accommodate changes in component-carrier configuration are mitigated by inserting a guard period each time the configuration of component carriers changes, so that transceiver reconfiguration can be carried out without interfering with ongoing transmission. A base station is configured to transmit data to a mobile station according to a first configuration of two or more component carriers, to determine that a change of configuration to a second component-carrier configuration is required, and to signal the change of configuration to the mobile station, using the first configuration of component carriers. The base station then refrains from transmitting data to the mobile station during a pre-determined guard interval of at least one transmission-time interval subsequent to the signaling of the change of configuration. After the guard interval, data is transmitted to the mobile station according to the second component-carrier configuration.

The UE includes a receiver configured to receive at least one semi-persistent scheduling (SPS) configuration among a plurality of SPS configurations from a BS. Each of the SPS configurations configures the UE with a different periodicity of a sidelink transmission to be transmitted to another UE. The UE also includes a transmitter configured to transmit the sidelink transmission in the different periodicity according to the at least one of the plurality of SPS configurations. The BS includes a controller configured to select at least one SPS configuration among a plurality of SPS configurations for a UE. Each of the SPS configurations configures the UE with a different periodicity of a sidelink transmission to be transmitted to another UE. The BS also includes a transmitter configured to transmit the selected at least one SPS configuration to the UE.

For flexible radio resource allocation, a processor receives a numerology scheme. The numerology scheme specifies one or more of at least frequency region definition and a sub-carrier spacing for the at least one frequency region. The method configures sub-carriers for at least one frequency region based on the numerology scheme.

A method provides for delivering video content from a server to a plurality of media devices is disclosed that distributes accurately excess bandwidth. The method includes: determining, by the server, the bandwidth to allocate to each of the plurality of media devices using a hypertext transfer protocol-based live streaming client model or a need parameter vector and/or measured bandwidth limitations associated with each of the plurality of media devices and providing the allocated bandwidth to each of the plurality of media devices, wherein the video content is transmitted in a plurality of segments from the server, and wherein each segment is transmitted at a bitrate that may vary from segment to segment.

A user equipment (UE) having a first capability associated with a lower maximum UE bandwidth than a second capability receives information for initial access using a first initial downlink bandwidth part (BWP) that is shared among UEs having the first capability and UEs having the second capability. The UE transmits a random access message in an initial uplink BWP that is dedicated for the UEs having the first capability.
