    Abstract: Various features presented herein facilitate early data transmission (EDT) in eMTC and NB-IoT. In certain aspects, a UE (e.g., an eMTC and/or NB-IoT type device), may receive an indication in a SIB from a base station that may enable EDT by the UE. The UE may transmit a random access request based on the SIB. The UE may further receive an MCS index in an RAR, and transmit a connection request (e.g., Msg3) to the base station based on the MCS index and the indication in the SIB. Some aspects described herein relate to an improved rate matching technique. In certain aspects, a UE may be configured to transmit a connection request message to a base station based on at least one of an increased number of RVs than a number of RVs for other transmissions from the UE or rate matching performed across more than one subframe.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a physical channel such as a narrowband physical broadcast channel (NPBCH) to supplement (e.g., or as an alternative to) reference signal measurements when determining a received signal measurement, such as a received signal strength or received signal quality of a cell. A base station may transmit an indication to a UE that identifies the frequency at which a portion of NPBCH transmissions (e.g., reserved fields of a master information block (MIB)) is expected to change from one NPBCH transmission to another. The UE may adjust its utilization of NPBCH for determining the received signal measurement based on the indication. Further, the UE may communicate with the cell based on the determination of the received signal measurement, which are based on the indication.

    Abstract: Methods, systems, and devices for wireless communication are described. The method includes transmitting a first barring bitmap associated with a first configuration of user equipments (UEs) based at least in part on a decision to implement access class barring (ACB), determining a radio access network (RAN) provides network service to UEs of a second configuration different from the first configuration, transmitting a delay tolerant barring indicator associated with the second configuration based at least in part on the decision to implement ACB and determining that the RAN provides network services to UEs of a second configuration.

    Abstract: Methods and devices are disclosed for enabling improved performance on a single-transmit multi-SIM wireless communication device. The wireless communication device may detect a voice communication on a modem stack associated with the first SIM and a data communication on a modem stack associated with the second SIM. The wireless communication device may identify a data rate used by the voice codec to encode uplink traffic channel (TCH) bursts in the voice communication, and determine whether the identified data rate used by the voice codec permits TCH burst cancellation. If it is determined that the identified data rate used by the voice codec permits TCH burst cancellation, the wireless communication device may downgrade a portion of the uplink TCH bursts scheduled on the modem stack associated with the first SIM.

    Abstract: A method for cell reselection by a wireless communication device is described. The method includes signal strength of cells in one or more inter-radio access technology (inter-RAT) frequencies while camped on a serving cell in a connected mode. On releasing the connected mode and before moving to idle mode on the serving cell, the method also includes prioritizing the cells in the one or more inter-RAT frequencies based on a RAT preference order and the signal strength. The method further includes reselecting to a highest priority cell whose signal strength meets a cell selection criterion.

    Abstract: A method for cell selection or cell re-selection by a wireless communication device in a Global System for Mobile Communications (GSM) network is described. The method includes obtaining signal-to-noise ratios (SNRs) associated with multiple cells. The method also includes delaying a camping decision until a broadcast control channel (BCCH) of a strong SNR cell is decoded. The SNR of the strong SNR cell is greater than the SNR of a high received signal strength indication (RSSI) cell. The method further includes camping on the strong SNR cell.
