Energy saving operations for wireless networks

A network controlling entity in a heterogeneous or local area network (such as a macro eNB) selects a set of network access nodes that share a common wake-up area code WUAC. The network controlling entity selects a transmission entity such as a motile terminal/UE and directs it to wirelessly transmit a signal on a given radio resource. The network controlling entity also informs each network access node within the set of the given radio resource on which they should listen for the signal. In various embodiments the network access nodes within the set can choose whether or not to listen for the signal and thus choose whether they will wakeup, or they can reply to the signal with a request for wakeup confirmation. In this manner WUAC-specific sets of small cells can be awakened only when needed for traffic offloading and thereby saving energy.

Techniques for co-existence on a shared communication medium are disclosed. An activation command may be received, over a backhaul connection and via a first Radio Access Technology (RAT), configuring the first RAT for active operation on a shared communication medium. An activity indicator may be generated based on the active operation of the first RAT. Based on the activity indicator, one or more measurements scheduled to be performed on the communication medium in accordance with a second RAT and a corresponding wakeup schedule may be disabled. Access of a first RAT to a shared communication medium may also be monitored. A priority indicator for the first RAT may be generated based on the monitored access. Based on the priority indicator, release of a backhaul connection on the communication medium that is associated with a second RAT may be coordinated.

DETERMINING WHEN TO RELAY A DATA UNIT IN A CELLULAR COMMUNICATION NETWORK

The system (1) of the invention is configured to receive information relating to relay devices (11, 17-19) present in a certain spatial area and determine relay configuration information for the relay devices from the information. The relay configuration information instructs the relay devices when to receive and/or relay data units and when not to receive and/or relay data units. The system is further configured to transmit the relay configuration information to the relay devices. The relay device of the invention is configured receive a data unit from a further device (21) or not in dependence on the received relay configuration information and/or relay a received data unit to the cellular communication network (31) or not in dependence on the received relay configuration information.

The present invention discloses a sleeping link waking method and apparatus, and relates to the field of communications network technologies, which can automatically wake a sleeping link in a timely manner according to an actual load condition of a network, and reduce labor maintenance costs. According to embodiments of the present invention, a first router receives a first LSP packet sent by a management router, where the first LSP packet includes a first TLV, and the first TLV is used to determine a sleeping link to be woken; the first router determines, according to the first TLV, the sleeping link to be woken; and the first router wakes the sleeping link. The solutions provided by the embodiments of the present invention are suitable to be used to wake a sleeping link.

Context-based coordinated data retrieval for mobile devices

Context-based coordinated data retrieval for mobile devices is provided. An interface between application code of a mobile device and an operating system of the mobile device receives a declarative language based data-retrieval request made by the application code for data from an I/O device of the mobile device. Based on operating context of the mobile device, opportunistic coordination rule(s) are selected from a local rules cache, the rule(s) representative of at least one power-saving option for retrieving data for responding to the request. The rule(s) are evaluated to determine how to retrieve data for responding to the request, and action(s) are performed based on the evaluating, the action(s) including responding to the request.

20170359779 · 2017-12-14 ·

A method and device for scheduling SR transmissions for a user equipment (UE) associated with an evolved Node B (eNB) of a Long Term Evolution (LTE) network. The method includes determining an SR is to be transmitted to the LTE network, determining an uplink grant behavior of the eNB, when the uplink grant behavior of the eNB indicates that previous uplink grants satisfy a threshold of previous grants occurring in onDurations of the cycle of a C-DRX functionality, selecting one of the at least one SR opportunity that follows a next onDuration relative to when the indication is received and scheduling the SR in the one of the at least one SR opportunity that follows the next onDuration. The method further including determining an uplink grant turnaround time associated with the eNB, and selecting one of the at least one SR opportunity based on the uplink grant turnaround time.

Management and setup of enhanced MAC-E/ES resources in cell-FACH state

A method and apparatus are disclosed to manage the enhanced medium access control-e (MAC-e) and enhanced MAC-es resources and respective variables for the enhanced dedicated channel (E-DCH) in the enhanced Cell_FACH state. Due to the nature of the E-DCH transmission in the uplink (UL) in the Cell_FACH state and the fact that a wireless transmit/receive unit (WTRU) might set up and release the E-DCH resources more frequently, methods to deal with the TSN numbering are described.

SMALL DATA EXCHANGE HANDLING BY A USER EQUIPMENT IN INACTIVE STATE

Various embodiments herein provide techniques for small data transmission of a user equipment (UE) in a radio resource control (RRC) inactive state. The techniques may be used with a next generation Node B (gNB) that employs a distributed unit (DU)/centralized unit (CU) split. The DU receives, from the UE in the RRC inactive state, data and processing information for processing for the data, processes the data based on a radio link control (RLC) bearer, and sends the processed data to the CU.

Methods and apparatus for detecting a voice command

According to some aspects, a method of monitoring an acoustic environment of a mobile device, at least one computer readable medium encoded with instructions that, when executed, perform such a method and/or a mobile device configured to perform such a method is provided. The method comprises receiving acoustic input from the environment of the mobile device while the mobile device is operating in the low power mode, detecting whether the acoustic input includes a voice command based on performing a plurality of processing stages on the acoustic input, wherein at least one of the plurality of processing stages is performed while the mobile device is operating in the low power mode, and using at least one contextual cue to assist in detecting whether the acoustic input includes a voice command.

Synchronized multi-sink routing for wireless networks

A method transmitting packets in a wireless network including a node, a first data sink and a second data sink is disclosed. The method performs a synchronization of the node with the first data sink and the second data sink and transmits first data packets from the node to the first data sink at a first allocated time synchronized with the first data sink. Next, the method transmits second data packets from the node to the second data sink at a second allocated time synchronized with the second data sink. The first and the second data packets are transmitted without updating the synchronization.
