Abstract: A method for reducing power consumption in connected mode discontinuous reception is disclosed. The method can include a wireless communication device sending a transmission for a pending HARQ retransmission process and receiving an ACK for the transmission. The method can further include the wireless communication device determining a subset of remaining uplink transmission opportunities in the pending HARQ retransmission process to monitor for an uplink grant in response to receiving the ACK and monitoring the subset of remaining uplink transmission opportunities for an uplink grant. The method can additionally include the wireless communication device entering a sleep state for any uplink transmission opportunities remaining in the pending HARQ retransmission process after monitoring the subset of remaining uplink transmission opportunities in an instance in which an uplink grant for the pending HARQ retransmission process is not received for any of the subset of remaining uplink transmission opportunities.

Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.

Abstract translation: 与包括基站（BS）的网络的连接可以由用户设备（UE）经由无线连接建立，用于使用在连续的不连续接收（C-DRX）模式中的半永久调度（SPS）进行通信。 可以相对于SPS激活命令和SPS间隔UL（对于上行链路）来调整SPS发送周期。 然后可以根据所确定的SPS发送周期在C-DRX持续时间周期期间发送数据。 在一些实施例中，调整SPS发送周期，使得在接收到SPS激活命令之后的第一C-DRX持续时间周期之后，SPS数据传输在每个随后的C-DRX持续时间段期间发生特定数量的子帧 比在第一个C-DRX持续时间段。 一旦UE设备在持续时间期间唤醒，可以在每个随后的C-DRX持续时间段中的SPS数据传输发生。

Abstract: A user identity module (UIM) is incorporated in user equipment such as a mobile phone or mobile device. The UIM is configured to provision itself while roaming away from a home network as follows. The UIM may: send to the UE a request for information identifying a current radio access technology (RAT) that the UE is camped on; receive the current RAT information from the UE; send to the UE a request for network location information, where the network location information identifies a network in which the UE is currently camped; receive the network location information from the UE; generate an access point name (APN) using the current RAT information and the network location information; and open a channel through the network to a remote agent (e.g., a provisioning server) using the access point name.

Abstract: A method includes a wireless mobile device communicating with a wireless network via an evolved high rate packet data (eHRPD) interface. The wireless mobile device may receive a vendor specific network control protocol (VSNCP) packet such as a terminate-request packet, for example, that indicates the wireless network has requested a PDN disconnection. The VSNCP packet includes a cause code that indicates a reason for the PDN disconnection request. The wireless device may use the cause code to determine the reason for the PDN disconnection request. Accordingly, in response to receiving the VSNCP packet, the wireless mobile device may perform one or more operations in an effort to resolve any issues that may have caused the PDN disconnection request.

Abstract: A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.
