Abstract: A method and apparatus for wireless communications are provided. A first cell on which a user equipment (UE) is camped may be identified as a visited Public Land Mobile Network (VPLMN) of the UE. Information of a second cell among neighboring cells of the first cell may be received via a broadcast message from the first cell. The second cell may be part of a home PLMN (HPLMN) and the HPLMN may not be an equivalent PLMN (EPLMN) to the VPLMN associated with the first cell. Alternatively, the second cell may belong to an Equivalent HPLMN (EPLMN). When the second cell is determined to be a best cell according to absolute priority reselection rules or a highest ranked cell among the neighboring cells of the first cell, the second cell may not be barred for a period of time from being considered or identified as a candidate for reselection.

Abstract: Disclosed are systems and methods for continuous inter-frequency measurement reconfigurations in a DC-HSUPA User Equipment (UE). In one aspect, the system may configure the UE to perform intra-frequency measurements on a frequency f1 and inter-frequency measurements on a frequency f2 in a dual carrier (DC) downlink (DL) mode and a single carrier (SC) uplink (UL) mode. The system may then reconfigure the UE to operate in a DC UL mode and continuing to perform inter-frequency measurements on the frequency f2 in the DC UL mode. The system may then reconfigure the UE to operate in the SC UL mode and continuing to perform inter-frequency measurements on frequency f2 in the SC UL mode.

Abstract: The present disclosure presents an improved method and apparatus for re-transmission of reconfiguration messages. For example, the disclosure presents a method for detecting that a reconfiguration complete message is transmitted from a user equipment (UE) to a network and initiating a reconfiguration re-transmission timer upon the detection. In addition, such an example method, may include determining that the UE has not received a layer two acknowledgement (L2 ACK) message for the transmitted reconfiguration complete message from the network prior to expiration of the reconfiguration re-transmission timer and triggering a cell update message to the network in response to the determination that the UE has not received the L2 ACK message. As such, improved re-transmission of reconfiguration messages may be achieved.

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.
