Abstract: This disclosure relates to techniques for a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.

Abstract: This disclosure relates to techniques for securely performing connection release and network redirection in a wireless communication system. A wireless device may establish a radio resource control (RRC) connection with a first cell. The wireless device may receive a RRC connection release message from the first cell. The RRC connection release message may include an indication to redirect the wireless device to a second cell. The RRC connection with the first cell may be released. It may be determined whether security has been established with the first cell when the indication to redirect the wireless device to the second cell is received. A new serving cell may be selected based at least in part on whether security has been established with the first cell when the indication to redirect the wireless device to the second cell is received.

Abstract: In at least some embodiments, a method, apparatus, and system for performing communication using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. A mobile device may be configured to receive information regarding traffic steering, i.e., cellular/short-range RAT handover, from nearby short-range access points and/or from a cellular base station. The mobile device may generate or determine mobility information of the mobile device, which indicates an amount of movement of the mobile device. The mobile device may determine whether the mobile device should transition between the cellular RAT and the short-range RAT based at least in part on the traffic-steering information and the mobility information. The mobile device may selectively transition between the cellular RAT and the short-range RAT based on the determination.

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: 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: A base station is disclosed that may communicate with a wireless device such as a user equipment (UE) using a dynamic frame structure. The base station may transmit control information on a control channel that dynamically specifies a first transmit time interval between control channel transmissions. The duration of the first transmit time interval may be determined based at least in part on a type of service executing on the UE, wherein the type of service may comprise one of machine type communications (MTC), enhanced mobile broadband (eMBB), and critical machine applications.

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.
