Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a transmission mode for transmission of an input signal to be transmitted. The input signal may thus be modulated according to the identified transmission mode, and the modulated signal may then be transmitted at some power level to produce a transmitted signal having a spectral envelope. In some cases, the spectral envelope may be defined in terms of a power spectral density (PSD) of the transmitted waveform. The PSD may generally define the power of the waveform signal distributed over frequencies of the waveform. Further, the wireless device may control the modulation of the input signal, in addition to the power level of the input signal, to maintain the spectral envelope to be within a spectral mask defined for the implemented transmission mode as well as to conform to spectral flatness parameters.

Additionally or alternatively, the described techniques may improve energy efficiency for communicating devices, reduce signaling overhead, or otherwise benefit a wireless communications system. Generally, the described techniques provide for efficient anchoring of high-band communications to low-band transmissions.

Abstract: Techniques for dynamically determining a Quality of Service (QoS) for wireless communications, and in particular, for 5G wireless communications, are discussed herein. For example, a user equipment (UE) can send a resource request to a base station associated with a radio access network (RAN). In some instances, the resource request can include identity information, such as an IMEI or an IMSI. The RAN can send a profile request to a user profile database, which can provide profile information to a policy control function (PCF) and/or the RAN. The profile information can be used to select a QoS for a communication associated with the UE based at least in part on the user profile information, a communication type, and/or a state of the network. The RAN can exchange data with the UE in accordance with the selected QoS to ensure various service levels associated with the communication.

Abstract: The disclosure is related to a bandwidth management method performed in a network switch and a network system. In the method, a total bandwidth usage is firstly metered, and it is determined if the total bandwidth usage reaches a threshold for triggering a flow-limit process.

In the flow-limit process, the class of a user is identified. Guaranteed bandwidth is provided for a prioritized user. A normal user will be restricted to using the bandwidth aside from the guaranteed bandwidth. The bandwidth provided for the normal user may exceed the available bandwidth based on an adjustable system parameter.
