Modifiable guard periods are provided for time division duplexing (TDD) wireless communications. Guard periods may be modified based at least in part on propagation delay information, such as timing advance (TA) information, for one or more user equipment (UE) in a TDD wireless system. Modifiable guard periods may allow for enhanced system efficiency for the TDD wireless system relative to systems that may use a static or semi-statically configured guard period for TDD communications. Modifiable guard periods may in some cases allow one or more uplink or downlink transmissions to be provided within a legacy guard period of a legacy TDD special subframe.

Methods and devices for the prioritization of random access procedure messages for high priority devices, such as for mission critical services. One or more of transmit power, repetition, table selection, P1/BPSK enablement, TB scaling, channel access and CP extension can be adapted for prioritize devices and messages.

Certain aspects of the present disclosure provide techniques for random-access channel (RACH) communication. For example, certain aspects provide a method for falling back from a 2-step RACH procedure to a 4-step RACH procedure.

Methods generally including determining a structure in the data; by the controller, determining a relevance of the determined structure in the data to at least one role type stored within a role taxonomy; by the controller, determining a reduced dimensionality view of the data in response to the determined structure in the data. The reduced dimensionality view comprises fewer dimensions than the data from the plurality of input sensors. The reduced dimensionality view further comprises a graphical element representing at least one of: mechanical portions of a machine of the industrial environment, or a sensor from the plurality of input sensors that provided data; and providing the reduced dimensionality view to a user interface that is associated with at least one entity associated with the at least one role type stored within the role taxonomy.

A wireless device receives a control message configuring cell groups comprising a first cell group and a second cell group. The wireless device receives a control command causing the wireless device to transmit a random access preamble on a secondary cell in the secondary cell group. Transmission timing of the random access preamble is determined, at least in part, employing uplink subframe transmission timing of the primary cell or a stored timing advance value.

The present invention is designed to allow user terminals to detect small cells in the off state efficiently when the small cells are switched on and off dynamically. A radio base station that switches between a continuous transmission state and a discontinuous transmission state dynamically, has a power control section that executes power control so that the transmission power of a reference signal for cell detection that is transmitted in the discontinuous transmission state is lower than the transmission power of a reference signal that is transmitted in the continuous transmission state.

Apparatuses, methods, and systems are disclosed for uplink power control. One method includes: receiving a message that configures a set of resources that each includes a downlink resource or an uplink sounding resource and is associated with an uplink transmission beam pattern; receiving scheduling information for an uplink transmission that is associated with a resource of the set of resources; determining an uplink transmission beam pattern associated with the resource; determining a configured maximum output power for the uplink transmission beam pattern that is based on an antenna array property associated with the uplink transmission beam pattern; determining a transmit power for the uplink transmission based on the configured maximum output power; and performing the uplink transmission using the uplink transmission beam pattern based on the transmit power.

Data storage structured to store a plurality of detection values relating to aspects of an industrial production process and data relating to at least one role type stored within a role taxonomy; a data analysis circuit structured to interpret at least a subset of the plurality of detection values to determine a state value comprising at least one of a process state or a component state; an optimization circuit structured to analyze a subset of the plurality of detection values and the state value using at least one of a neural net or an expert system to determine a signal effectiveness of at least one of the plurality of input channels relative to the state value, and to provide an adjustment recommendation based, at least in part, on the signal effectiveness; and an analysis response circuit structured to adjust the industrial production process in response to the adjustment recommendation.

Systems, methods, and apparatuses are described for wireless communications. A wireless device may transmit an uplink signal via a cell of a cell group. Transmission timing of the uplink signal may be based on a cell of the cell group and a timing adjustment associated with a different cell group.

Disclosed are a method, network device, and system for transmit power control during D2D communication. The method comprises: a network device determines the maximum allowed transmit power of a first terminal on the basis of the maximum level of interference that a cellular network can handle and/or the maximum level of interference that the first terminal is allowed to cause to a receiving terminal, and sends said maximum allowed transmit power of the first terminal to the first terminal, said first terminal being the sending device of D2D communication; and the first terminal determines transmit power on the basis of said maximum allowed transmit power. By means of the present technical solutions, when determining transmit power, a D2D sending device takes into account the maximum interference a cellular network can handle and/or the maximum level of interference that may be caused to a receiving terminal, thereby reducing the interference caused to D2D communicating terminals or to terminals of other cells using the resources of a cellular network.
