A method of operating an optical-wireless access system, wherein an ONU obtains information on dynamic scheduling control of the optical-wireless access system, information on discontinuous reception control of the optical-wireless access system, or both of them, and such information is used in the ONU or transferred to an OLT and used as parameters of scheduling in the PON and sleep control.

A device reduces its energy consumption using a relatively lower frequency and lower power secondary oscillator to maintain timing information when a higher frequency and higher power primary oscillator is inactivated. The secondary oscillator maintains timing information at a higher resolution than the period of the oscillator, so as to conserve synchronization when the higher frequency, higher power primary oscillator is inactivated. In some embodiments, a microsequencer is programmably configured to control an integrated radio receiver and transmitter using less power than an associated microprocessor would use to perform the same functions. In other embodiments, flexible event timing facilitates the merging of wake-up events to reduce the energy consumed by wake-up operations in the device.

A system and method to optimize a multiple-input multiple-output signal processing RF communication system that includes obtaining, by a processor, at the receiver, during spatial processing, metrics from the channel stream. The metrics include a spatial correlation metric representing spatial coupling between multiplexed streams in the channel stream, a signal-to-noise power ratio metric representing propagation losses encountered by the signal, and a cross polarization discrimination metric representing whether polarization modes can be processed as independent groups. The processor obtains these metrics based on obtaining geometric information related to the receiver and the transmitter. Predictive methods may be employed to determine expectations for some metrics in advance. The method includes applying a policy with at least one objective of the system, and based on at least one metric and the policy, applying at least one adaptation to at least one of: the receiver or, the transmitter.

Systems, devices, and configurations to implement trusted connections within wireless networks and associated devices and systems are generally disclosed herein. In some examples, a wireless local area network (WLAN) may be attached to a 3GPP evolved packet core (EPC) as a trusted access network, without use of an evolved packet data gateway (ePDG) and overhead from related tunneling and encryption. Information to create the trusted attachment between a mobile device and a WLAN may be exchanged using Access Network Query Protocol (ANQP) extensions defined by IEEE standard 802.11u-2011, or using other protocols or standards such as DHCP or EAP. A trusted WLAN container with defined data structure fields may be transferred in the ANQP elements to exchange information used in the establishment and operation of the trusted attachment.

The DRX configuration method includes: receiving, by a terminal device, N discontinuous reception DRX configurations sent by a network device, where the N DRX configurations respectively correspond to N groups of carriers; and when a DRX status of the terminal device is an active state, if M groups of carriers in the N groups of carriers are activated carriers, monitoring, by the terminal device, a physical downlink control channel on a specified carrier based on M DRX configurations corresponding to the M groups of carriers.

In addition, the terminal device simultaneously uses the plurality of DRX configurations in an overlay manner, so as to reduce unnecessary physical downlink control channel monitoring in a process of monitoring the physical downlink control channel, thereby reducing energy consumption of the terminal device.
