A method for controlling carrier load, a network device and a user equipment (UE) are provided. The method comprises: configuring an uplink bandwidth part set and a downlink bandwidth part set for a UE according to broadcast information, wherein the uplink bandwidth part set comprises at least two uplink bandwidth parts, and the at least two uplink bandwidth parts are a part of all uplink bandwidth parts that the network device can allocate; at least two uplink bandwidth parts comprises at least one first uplink bandwidth part comprising physical random access channel (PRACH) resource configuration information; the downlink bandwidth part set comprises at least two downlink bandwidth parts, and the at least two downlink bandwidth parts are a part of all downlink bandwidth parts that the network device can allocate.

A method of supporting active bandwidth part (BWP) switching under carrier aggregation (CA) is proposed. To avoid longer switching delay and multiple interruptions in other component carriers (CCs)/cells, the starting time of the later active BWP switching in one cell should fall outside the switching delay of the earlier active BWP switching in another cell. If the later active BWP switching is DCI-based, then the network should schedule the later active BWP switching outside the switching delay of the earlier active BWP switching. If the later active BWP switching is timer-based, then the UE should not perform the later active BWP switching until the earlier active BWP switching is completed.

The concepts relate to radio channel utilization. One example can channel bond a first available channel from a first radio frequency band with a second available channel from a second radio frequency band. The example can transmit a portion of a forward error correction coded data stream over the first available channel and a different portion of the forward error correction coded data stream over the second available channel.

Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for scheduling of multiple uplink transmissions in unlicensed spectrum. One embodiment involves receiving, at an eNB, first uplink scheduling request from a UE, scheduling a plurality of uplink subframes on the unlicensed channel in response to the first uplink scheduling request, and initiating transmission of a first subframe to the first UE in response to the scheduling of the plurality of uplink subframes, wherein the first subframe comprises one or more downlink control indicators (DCIs) allocating the plurality of uplink subframes to the first UE.

A method and apparatus for allocating resources to a low cost user equipment (UE) in a wireless communication system is provided. A base station (BS) allocates at least one sub-bandwidth among a system bandwidth to a low cost UE, and transmits information on the allocated at least one sub-bandwidth to the low cost UE. The at least one sub-bandwidth may include a set of resource physical resource blocks (PRBs) that the low cost UE can access at a given subframe.

The present invention discloses an indication information transmission method and apparatus. The method includes determining a first signature sequence and a first modulation constellation that are used to transmit a first downlink data stream to a terminal device and determining one or more second signature sequences and one or more second modulation constellations that are used to transmit a second downlink data stream. The method also includes determining indication information that is used to indicate the first signature sequence, the first modulation constellation, the one or more second signature sequences, and the one or more second modulation constellations and transmitting the indication information to the terminal device.

This disclosure includes a method, and a device for implementing the method, for creating a channel for transmitting data on a Digital Subscriber Line (DSL) connection, the method comprising: method for creating a channel for transmitting data on a Digital Subscriber Line (DSL) connection, the method comprising: defining a plurality of sets of tones, wherein each set of tones includes one or more tones used by a DSL connection; monitoring the transmission characteristics of each set of tones in the plurality of sets of tones; and creating a first channel for transmitting data on the DSL connection, including allocating a first set of tones of the plurality of sets of tones to the first channel based on the monitored transmission characteristics of the first set of tones and the transmission requirements of the first channel.

The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may measure one or more candidate bandwidths, each of the one or more candidate bandwidths corresponding to a candidate channel. The apparatus may also select an operating bandwidth of the one or more candidate bandwidths based on the measured one or more candidate bandwidths, the operating bandwidth corresponding to an operating channel. Additionally, the apparatus may adjust an energy detection threshold of a reference bandwidth based on a sensing bandwidth. The apparatus may also determine whether a transmission medium is available based on at least one of the adjusted energy detection threshold or an interference level of at least one signal.

Aspects of the disclosure relate to techniques for peak-to-average power ratio (PAPR) reduction based on a tone reservation (TR) algorithm. For a TR algorithm, a suitable subset of tones from among a full set of tones in a given resource allocation are reserved for use as peak reduction tones (PRT). An apparatus such as a transmission/reception point receives a set of one or more PRT sequences and stores them in memory. The transmission/reception point then determines a set of PRTs based on one or more later-received PRT sequence selection parameters. Other aspects, embodiments, and features are also claimed and described.
