Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) operating in a narrowband communications system with a base station may identify a radio link failure (RLF) and then initiate a radio resource control (RRC) connection reestablishment procedure to reconnect with the base station. As part of the connection reestablishment procedure, the UE may transmit a reestablishment complete message to the base station to indicate the connection reestablishment procedure is successful and include a measurement report related to downlink signals received from the base station in the reestablishment complete message. In some cases, the measurement report may include an indication of downlink signal strength and downlink signal quality. As such, the UE may transmit the measurement report in a single RRC message after identifying the RLF. Based on the measurement report, the base station may then perform network planning.

Abstract: Certain aspects of the present disclosure relate to apparatuses and methods for maintaining reachability at a user equipment (UE). In one aspect, the apparatuses and methods are configured to detect a change in a radio connection between the UE and a peer entity, wherein the change in the radio connection is associated with the UE entering an idle state, to communicate to the peer entity, in response to detecting the change in the radio condition, an indication that the UE is to enter the idle state and is reachable for a specified duration of time while in the idle state, and to enter the idle state after communicating the indication to the peer entity. In another aspect, the apparatuses and methods are configured to communicate to the peer entity an indication that the peer entity is not to attempt to reach the UE during the specified duration of time.

Abstract: Methods, systems, and devices for wireless communication are described. Data for a broadcast or multicast service may be sent over a control channel. A network device may broadcast a message to indicate a plurality of enhanced multimedia broadcast multicast service (eMBMS) services offered by the network. The mobile device may transmit an indication to the network device identifying an eMBMS service of interest. The network device may transmit a configuration message before broadcasting or multicasting data of the eMBMS service of interest. The configuration message may notify the mobile device of a control channel on which to receive the data related to the eMBMS service. The network device may then broadcast or multicast the eMBMS service data on the control channel. The data may be segmented at a particular protocol layer and mapped to several transmission time intervals within each repetition of the control channel.

Abstract: Wireless communication at a user equipment (UE) is described. In some cases, a UE may determine that a voice call is about to be setup or in the process of being setup with a cell that supports voice calls. While the voice call is pending, the UE may be motivated to connect to a cell that does not support voice calls. The UE may recognize that the cell does not support voice calls and refrain from connecting to the cell until after the voice call setup, and/or the voice call itself, has completed.

Abstract: Methods, systems, and devices are described for handling over-sized call setup messages are disclosed. A user equipment (UE) may identify the size of a connection setup message (e.g., RRC connection setup complete message) associated with one or more UE capability information. Based on the identified size of the connection setup message, the UE may determine an estimated time required to transmit the connection setup message to a network entity (e.g., base station) over at least one uplink channel and determine whether the estimated time is above or below a threshold. If the UE determines that the estimated time to transmit the connection setup message is greater than the threshold, the UE may remove at least a portion of the connection setup message and transmit a modified connection setup message.

Abstract: Aspects of the disclosure provide for a method of efficiently implementing security configurations for multiple domains between a network entity and a UE in a wireless system. For instance, this disclosure provides for a network entity sending to a UE a first security mode command for a first domain, receiving a first security mode complete message in response to the first security mode command, and sending a second security mode command for a second domain. In an aspect, the second security mode command is sent in response to receiving the first security mode complete message. In an aspect, the UE does not receive a RLC acknowledgement. In another aspect, the UE saves the second security mode command until it receives the RLC acknowledgement. In an aspect, the network entity sends the second security mode command in response to receiving a message protected with first security procedure parameters.

Abstract: In aspects for controlling transmit power of dual carrier uplink transmission for wireless communications, a user equipment (UE) determines presence of transmit power imbalance between a first and second radio frequency (RF) carrier of respective dedicated physical control channels for uplink transmission. The UE determines an estimate of a remaining available transmit power after estimating the transmit power used by each of the dedicated physical control channels. The UE allocates the estimated remaining available transmit power to the first and second RF carrier respectively based on both a size of data granted for uplink transmission on each RF carrier and on an effective power per bit on each RF carrier. Additionally, the UE determines a higher reliability value for each RF carrier based on a lower data error rate, identifies priority values for data to be transmitted and sends higher priority data over the RF carrier with higher reliability value.
