The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting, by a user equipment (UE), data in a wireless communication system, the method comprising: receiving a physical downlink control channel (PDCCH) scheduling a physical downlink shared channel (PDSCH); triggering transmission of a scheduling request (SR); and if a transmission time interval (TTI) for an SR transmission is part of reception of the PDSCH, instructing a physical layer to transmit the SR after the PDSCH reception is completed.

The present invention relates to methods and apparatuses for transmitting data in a multicarrier telecommunication system and in particular for performing modulation and coding for low transmission power data. Scheduling information indicating resources on which a terminal is scheduled to transmit data is received at the terminal. The scheduling information includes a modulation and coding indicator set. Data are transmitted on the scheduled resources in accordance with a modulation and coding indicator in the modulation and coding indicator set and with a transmission parameter of the data to be transmitted.

The system supports a virtual carrier mode of operation in which downlink communications are made by a base station using a radio interface that spans a system frequency bandwidth while a terminal device is configured to receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth. The system supports terminal devices in both a radio resource control connected mode and a radio resource control idle mode. When there is to be a change in system information the base station transmits to the terminal device an indication that updated system information is to be broadcast by the base station and this indication is received by the terminal device while in the connected mode. Before seeking to acquire the updated system information, the terminal device transitions from the connected mode to the idle mode.

A wireless device receives downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) transmission. The wireless device transmits, in response to the DCI not comprising a sounding reference signal (SRS) resource indicator (SRI) field, a first repetition and a second repetition of the PUSCH transmission. The wireless device transmits the first repetition with a first transmission power determined based on a first power control parameter set comprising a first target received power. The wireless device transmits the second repetition with a second transmission power determined based on a second power control parameter set comprising a second target received power.

[Object] To make it possible to appropriately decode a data signal when multiplexing is performed using power allocation. [Solution] There is provided a device including: an acquisition unit configured to acquire information on power allocation to a data signal serving as a target for multiplexing using power allocation; and a reporting unit configured to report the information on the power allocation to a terminal device.

In embodiments, apparatuses, methods, and storage media may be described for identifying subframes in a radio frame on which a UE may receive a Physical Downlink Control Channel (PDCCH) or enhanced PDCCH (ePDCCH) transmission. Specifically, the UE may receive multiple indications of uplink/downlink (UL/DL) subframe configurations and identify one or more subframes in which the UE may receive the PDCCH or ePDCCH transmission. The UE may then monitor one or more of the identified subframes and base discontinuous reception (DRX) timer functionality on one or more of the identified subframes.

A station (STA) that communicates with an access point (AP) in a Wireless Local Area Network (WLAN) system includes a transceiver configured to support transmission and reception of signals within at least a first bandwidth and to receive a first physical layer protocol data unit (PPDU) conforming to a second bandwidth greater than the first bandwidth, and processing circuitry configured to support a wider bandwidth than the first bandwidth by obtaining a second PPDU allocated to the STA within the first bandwidth from the first PPDU. The processing circuitry is configured to control the transceiver to transmit, to the AP, performance information indicating first modulation and coding schemes (MCSs) supportable in the wider bandwidth according to a capability of the STA, among a plurality of candidate MCSs.

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for collision handling. A first network node receives a first allocation of first resources at a first time and receives a second allocation of second resources at a second time, wherein the first time is before the second time, wherein one or more of the first resources overlap in a time domain and a frequency domain with one or more of the second resources, and wherein the first resources are uplink resources and the second resources are downlink resources or the first resources are downlink resources and the second resources are uplink resources. The first network node adjusts for the overlap in the time domain and the frequency domain between the first allocation of first resources and the second allocation of second resources.

Systems, methods, and instrumentalities are disclosed for non-orthogonal multiple access (NOMA), frequency hopping, and power control. NOMA may be applied to asynchronous and/or grant-free transmissions. Transmissions from multiple WTRUs may be performed using the same resources, and may comprise information for correctly identifying and decoding the transmissions. The transmissions may comprise a built-in deterministic sequence to support timing acquisition at a receiver. The transmissions may be distinguished based on respective transmit power used for the transmissions. Such transmit power may be dynamically controlled by applying a randomly selected power offset. The power control may be performed autonomously by a WTRU.

A method includes: communicating, by a base station, first UE specific information of UE with the UE in a UE source operating bandwidth resource; and sending, by the base station, information about a UE target operating bandwidth resource of the UE to the UE in a UE calibration bandwidth resource of the UE, where the UE target operating bandwidth resource is used by the base station to communicate second UE specific information of the UE with the UE, and the UE source operating bandwidth resource is not completely the same as the UE calibration bandwidth resource.
