Abstract: The present disclosure provides reduced cell-specific reference signal (CRS) transmissions for evolved machine type communication (eMTC). In one aspect, a network entity may determine at least one narrow band for transmission of a CRS. The network entity may further identify one or more resource blocks proximate the at least one narrow band and transmit the CRS on the narrow band and the one or more proximate resource blocks to a UE. In another aspect, a UE may apply a receive window to filter one or more noise samples outside at least one narrow band allocation, the receive window corresponding to one or more resource blocks located outside the defined number of resource blocks of the at least one narrow band allocation. The UE may further receive the CRS within the at least one narrow band allocation from a network entity in response to applying the receive window.

Abstract: Certain aspects of the present disclosure provide techniques for higher bandwidth and data rate for enhanced machine type communications (eMTC). According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes determining frequency resources within one or more configured narrowband regions of a system bandwidth to monitor for a transmission and monitoring for the transmission on the determined frequency resources within the one or more narrowband regions of the system bandwidth.

Abstract: Techniques and apparatus for early termination of decoding of communication channels for power saving in narrowband devices are provided. One technique includes monitoring for one or more first repetitions of at least one communication channel from a base station. The device determines, based on the monitoring, whether to refrain from monitoring for one or more second repetitions of the at least one communication channel. The device enters a low power mode if the determination is to refrain from monitoring for the one or more second repetitions of the at least one communication channel.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus may allocate one or more narrowbands for at least one downlink transmission to a UE. The apparatus may transmit information associated with the one or more narrowbands and a RIV to the UE. In one aspect, the RIV may indicate a common starting RB and a common set of RBs allocated for the at least one downlink transmission in each of the one or more narrowbands.

Abstract: The present disclosure provides a mechanism that may allow a UE to determine whether PBCH repetition is enabled in the target cell without performing a hypothesis test. For example, the apparatus may receive a handover message from a serving cell. In an aspect, the handover message may be associated with a handover procedure to a target cell. In addition, the apparatus may determine whether to perform a hypothesis test to determine if a PBCH repetition is enabled in the target cell based on the handover message. In one example, the apparatus may determine not to perform the hypothesis test when the handover message includes information that indicates if the PBCH repetition is enabled in the target cell. In another example, the apparatus may determine to perform the hypothesis test when the handover message does not include information that indicates if the PBCH repetition is enabled in the target cell.
