Abstract: A user equipment (UE) device may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and/or additional optimization requirements. The UE device may communicate with a cellular base station according to a first mode of operation associated with the new device category, and may switch to communicating with the cellular base station according to a second mode of operation associated with a second (pre-existing) device category in response to the link budget requirements exceeding a specified value and the quality of service requirements not being sensitive. The UE device may also switch to communicating with the cellular base station according to a third mode of operation associated with a third (pre-existing) device type in response to the link budget requirement not exceeding the specified value, or the QoS requirements being sensitive and a downlink throughput requirement exceeding a specified throughput value.

Abstract: In a method of device-to-device communication, a user device initially sends an emergency message repeatedly at a first repeating frequency. When a specified number acknowledgement (ACK) messages are received, the user device sends the emergency message repeatedly at a reduced repeating frequency. The repeating frequency may be further reduced when more ACK messages are received.

Abstract: An electronic device discussed herein may include radio frequency communication circuitry for communication on a radio frequency network according to a communication configuration, a processor, and memory. The memory may store instructions that, when executed by the processor, cause the electronic device to perform operations including receiving, a first muting configuration indicating when the radio frequency communication circuitry is to communicate using a first type of communication on a first frequency band and when the radio frequency communication circuitry is to communicate using a second type of communication on a second frequency band, where the first frequency band may overlap with the second frequency band. The memory may store instructions that, when executed by the processor, cause the electronic device to perform operations including transmitting or receiving a data packet using the radio frequency communication circuitry according to the communication configuration.

Abstract: This disclosure relates to techniques for providing robust downlink control information with flexible resource assignments for wireless devices that operate in a restricted bandwidth compared to the system bandwidth. A base station may determine a resource assignment for a wireless device. The base station may transmit downlink control information to the wireless device. The downlink control information may include an indication of a resource assignment for the wireless device. The indication of the resource assignment may include an indication of a first narrowband associated with the resource assignment, and an indication of whether one or more additional narrowbands are associated with the resource assignment. The base station and the wireless device may communicate data according to the resource assignment.

Abstract: In a method of device-to-device communication, efficient power management is provided when a primary device has a low battery level. The primary device can send synchronization signals and discovery messages to secondary devices by looping through a sequence of transmit power values in a sequence of consecutive frames, where the sequence of transmitting values includes a default power value and a reduced power value.

Abstract: A wireless communication device (UE) may monitor grants received from respective cells associated with one or more first (e.g. licensed) frequency band(s) and one or more second (e.g. unlicensed) frequency band(s). Based on the received grants the UE may determine if an imbalance exists in the radio resource allocation, whereby the UE communicates more than intended in the second frequency band(s). The imbalance may be specified with respect to the ratio or portion of the communications that are conducted in the second frequency band(s) with respect to all wireless communications of the UE. If the UE detects an imbalance, it may transmit a report to the network (e.g. to the base station serving the UE) indicating unfavorable conditions for the UE to be operating in the second frequency band(s). In response, the network may disable the respective cell(s) associated with the second frequency band(s) and/or it may disable carrier aggregation for the UE.

Abstract: This disclosure relates to techniques and devices for implementing an emergency power save mode (EPSM) in a user equipment device (UE). A UE may enter the EPSM in response to user input. While operating in the EPSM, the UE may power down a display of the UE to preserve battery life and may broadcast an emergency beacon in response to user input to a hardware button of the UE, such as a volume button. The UE may supply sound or haptic feedback in response to broadcasting the emergency beacon.

Abstract: A wireless communication device may conduct first wireless communications over a first frequency band according to a first radio access technology (RAT), and may detect second wireless communications conducted over the first frequency band according to a second RAT while the wireless communication device is conducting the first wireless communications. The wireless communication device may then adjust characteristics and/or parameters associated with the first wireless communications based on the detected second wireless communications. In a specific example, a wireless communication device conducting Wi-Fi communications in the 5 GHz band may detect cellular communications (e.g. LAA/LTE-U communications) also conducted in the 5 GHz band while the wireless communication device is conducting the Wi Fi communications. The wireless communication device may then adjust characteristics and/or parameters associated with its Wi-Fi communications based on the detected signals/frequencies of the cellular (LAA/LTE-U) communications.

Abstract: This disclosure relates to techniques for selecting operational modes of a wireless device. The operational mode may be selected based on determining the presence or absence of reference symbols. A low power mode may be selected when the presence or absence of reference symbols suggests that a control channel used by the wireless device may not be present.
