Determining a power control group boundary includes receiving a plurality of samples having power control groups, where each power control group corresponds to a time period. The following are repeated for a predetermined number of iterations: a window is set at a point of a sample; a number of power control bits within the window at the point is determined; and the window is moved to a point of a next sample. A point at which the window has the largest number of power control bits is identified. A power control group boundary is determined in accordance with the window at the identified point.

A digital polar transmitter includes a baseband processor configured to receive an input signal and to convert the input signal into a baseband amplitude component and a baseband phase component. The transmitter also includes a phase modulator in communication with the baseband processor. The phase modulator is configured to modulate an RF carrier signal based on the phase component and to generate a phase-modulated RF carrier signal. A power amplifier is provided in communication with the baseband processor and the phase modulator. The power amplifier is configured to amplify the phase-modulated RF carrier signal based on the baseband amplitude component and to generate an amplified RF signal. The transmitter also includes a digital feedback loop in communication with the power amplifier and the baseband processor. The digital feedback loop is configured to detect the amplified RF signal and to provide a digital amplitude feedback signal and a detected phase feedback signal to the baseband processor.

An apparatus may include a non-linear module, a control module, and a calibration module. The non-linear module produces an output signal from an input signal. The control module selects, upon an occurrence of a calibration condition, a calibration operation from two or more calibration operations. Each of the two or more calibration operations may generate one or more correction values for the non-linear module. Further, each of the calibration operations produces the input signal from a pre-input signal. This selected calibration operation is performed by the calibration module. The two or more calibration operations include a first calibration operation and a second calibration operation. The first calibration operation produces the input signal from the pre-input signal according to a predictive technique. The second calibration operation produces the input signal from the pre-input signal according to a non-predictive technique.

A method and apparatus are described for providing triggering services over multiple access networks. A triggering service server (TSS) architecture includes a triggering identity function (TIF) which maintains a database of device and application identifier mappings across multiple access networks, triggering capabilities and triggering preferences. The TSS also includes a triggering decision function (TDF) that uses information from the TIF and determines how triggers should be performed towards a device and/or an application hosted on a particular device. The TSS also includes triggering gateways (T-GWs) that perform triggering in different domains. A “not-registered-triggerable” state may be used to indicate whether an entity, such as a device, application or user can receive triggers although it is not registered in a specific access network. Methods and apparatus are also described for implementing various unassisted triggering and assisted triggering procedures using wireless transmit/receive units (WTRUs), application servers (ASs) and service capability servers (SCSs).

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a configuration message including at least one information element indicating whether the UE is permitted to initiate sidelink-based positioning sessions, and transmits a positioning reference signal (PRS) request to at least one UE based on the at least one information element indicating that the UE is permitted to initiate sidelink-based positioning sessions.
