Abstract: Embodiments relate to apparatus, systems, and methods for reception of calls on a mobile device that includes Wi-Fi and cellular radios. The mobile device may be configured to establish communication on a Wi-Fi network with a cellular carrier. The mobile device may further be configured to register a first IP address with an IMS server for the Wi-Fi network communication and register a second IP address with the IMS server for the cellular network communication (or register different ports of a single IP address with Wi-Fi and cellular).

Abstract: Wireless communication devices (UEs) may include multiple receive (RX) chains and associated antennas, and at least one transmit (TX) chain co-located with one of the RX chains. The UE may track instant fading of the antenna gain(s) during reception of packets from an associated access point (AP) device to which the UE intends to transmit packets. The UE may also track long term antenna gain(s), using any packets received at the multiple RX chains within the UE. At a switching occasion, a decision is made by the UE whether to switch antennas. If the instant fading detection is based on packets received no later than a specified time period prior to the switching occasion, then the UE may make the switching decision based on the results of the instant fading tracking. Otherwise, the UE may make the switching decision based on the results of the long term antenna gain tracking. The wireless communication devices may also evaluate signal strength during transmission of the RX packets, and/or may evaluate a possible imbalance (gain difference) between the multiple RX chains within the wireless communication device. Signal strength detection may be enabled when non-MIMO transmissions are taking place, while imbalance detection (antenna gain comparison) may be enabled when a specified number of single-stream packets have been received. Once the decision has been made to operate in a reduced number RX path mode, decision to reactivate one or more additional RX paths may be made based on MIMO detection, a detection of a drop in signal quality, and/or upon expiration of a power save timer.

Abstract translation: 无线通信设备（UE）可以包括多个接收（RX）链和相关联的天线，以及与RX链中的一个共同定位的至少一个发射（TX）链。 UE可以在接收来自UE打算发送分组的相关接入点（AP）设备的分组期间跟踪天线增益的即时衰落。 UE还可以使用在UE内的多个RX链处接收到的任何分组来跟踪长期天线增益。 在切换时刻，由UE决定是否切换天线。 如果即时衰落检测是基于在切换时刻之前的指定时间段之前接收的分组，则UE可以基于即时衰落跟踪的结果进行切换决定。 否则，UE可以基于长期天线增益跟踪的结果进行切换决定。 无线通信设备还可以评估RX分组的传输期间的信号强度，和/或可以评估无线通信设备内的多个RX链之间的可能的不平衡（增益差）。 当正在进行非MIMO传输时，可以启用信号强度检测，而当接收到指定数量的单流分组时，可以启用不平衡检测（天线增益比较）。 一旦做出了以减少数量的RX路径模式操作的决定，可以基于MIMO检测，信号质量下降检测和/或在功率失效时进行重新激活一个或多个附加RX路径的决定 保存定时器。

Abstract: A device and method generates a hopping scheme for mobile stations of a wireless network. The method includes receiving a number of channels N of the wireless network. The method includes generating a shuffling matrix as a function of the number of channels N, each row of the shuffling matrix being indicative of a respective one of the mobile stations, each column of the shuffling matrix being indicative of a respective broadcast time of a discovery signal in a hopping scheme. The method includes generating the hopping scheme for the mobile stations in the channels as a function of the shuffling matrix. The hopping scheme maximizes an interval between two consecutive broadcast times that any two of the mobile stations are assigned to transmit discovery signals on adjacent channels.

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: Providing a power-saving mode for control channel monitoring in discontinuous reception (DRX) scenarios. Upon waking from a sleep mode at the conclusion of a DRX off period, a baseband modem may transition to a low-power mode configured to receive and decode only a control channel, such as a physical downlink control channel (PDCCH). If the control channel indicates during a DRX on period that communication traffic will be transmitted to the baseband modem, then the baseband modem may transition to a full-power mode to receive the communication traffic. Otherwise, the baseband modem may transition back to the sleep mode. The low-power mode may be implemented by a dedicated set of hardware configured to draw less power than a full set of hardware configured to implement the high-power mode.

Abstract: In order to improve the communication performance and communication reliability of an electronic device, a communication quality metric is determined based on information communicated via a wireless network using a single antenna. For example, the communication quality metric may be determined based on acknowledgment (ACK) and negative-acknowledgment (NACK) messages in the communicated information or a number of packets retransmitted and a number of new packets transmitted in the communicated information. Then, one of at least two antennas is selected based on the determined communication quality metric. In this way, the electronic device may effectively use a single receive chain to provide improved communication of the information.
