Abstract: Aspects of the present disclosure relate to a multimode user equipment (UE) that when suffering a power crunch, can intelligently reselect to another RAT to extend the battery life of the UE. The reselected RAT has a lower specified maximum transmit power relative to the currently attached RAT. Therefore, the UE may reduce its battery drain to extend its service time per charge when a call is made utilizing the reselected RAT. The UE intelligently selects the RAT that will likely consume less uplink transmit power to communicate with a base station in order to conserve battery power in a poor coverage area, when the UE is experiencing a power crunch condition.

Abstract: A method for improving device-to-device (D2D) communication in an LTE-Direct communication system includes exchanging communication information between a first user equipment (UE) and a second UE over an LTE-Direct connection with a first network resource of a first set of network resources allocated to the first and second UEs by a base station for the LTE-Direct connection. The method also includes determining, by the first UE, whether a first link quality of the LTE-Direct connection with the first network resource is below a link quality threshold. If so, the LTE-Direct connection is shifted to another network resource of the first set of network resources until an LTE-Direct connection is established that has a link quality that is equal to or greater than the link quality threshold.

Abstract: Various embodiments implemented on a mobile communication device provide methods for skipping power measurements of frequency bands included in a list of frequency bands received from a first subscription's network to conserve power and to increase the likelihood of avoiding a coexistence event between a first subscription and a second subscription. Specifically, a processor of the mobile communication device may order the list of frequency bands such that non-interfering frequency bands are ordered before interfering frequency bands. The processor may then take power measurements of frequency bands in the list, in order, until the processor determines that a power measurement has satisfied a minimum power threshold. In response to such a determination, the device processor may report the power measurement that satisfies the minimum power threshold to the first subscription's network and may not take any more power measurements of the remaining frequency bands in the list.

Abstract: Methods, systems, and devices are described for acquiring a network by a user equipment (UE) by concurrently scanning for a network signal on supported frequencies by two or more antennas. In one aspect, a method may include searching by a first antenna for a first signal on a first group of supported frequencies while concurrently searching by a second antenna for the first signal on a second group of supported frequencies. The method may further include acquiring the first signal from the first antenna on a first frequency, and tuning the second antenna to the first frequency to acquire the wireless network. In one aspect, the first and second groups of supported frequencies may represent frequencies within a single frequency band or frequencies in multiple frequency bands. In one aspect, supported frequencies may be divided into multiple groups and each group may be searched by a corresponding antenna.

Abstract: Minimizing conflicts between different radio access technologies (RATs) is disclosed herein which include monitoring, by a user equipment (UE), a first use of a UE Radio Frequency (RF) resource by a first Radio Access Technology (RAT). The UE monitors a second use of the UE resource by a second RAT. The UE is served by a current serving cell in the second RAT. The UE may also determine a percentage of conflict between a first use of a UE resource by a first RAT and the second use of the UE resource by the second RAT over a predefined period of time, and initiating, by the UE, a cell reselection attempt to one or more neighboring cells of a plurality of neighboring cells serving the second RAT based on the determined percentage of conflict exceeding a predetermined threshold.

Abstract: Methods, systems, and apparatuses are described for advertising information corresponding to beamforming techniques supported by base stations of a wireless communications system, which in various examples may include analog, digital, and/or hybrid beamforming techniques supported by millimeter wave (mmW) base stations. Advertising of supported beamforming techniques may involve transmissions over a nearby long term evolution (LTE) or another carrier frequency network (e.g., in case of LTE/lower carrier frequency assisted mmW wireless access networks). Alternatively or additionally, advertising may employ broadcasting from a mmW base station, which may include mmW beam sweeps. A UE may receive information corresponding to supported beamforming techniques, and may use the received information to select a particular mmW base station with which to communicate or to determine a transmission strategy for communicating with a particular mmW base station, or both.
