    Abstract: Embodiments include systems and methods that may be performed by a processor of a multi-subscription wireless device for managing beam selection. Various embodiments may include determining a rotation angle between an orientation of a first beam of a first subscription and an orientation of a second beam of the first subscription, applying the rotation angle to a first beam of a second subscription to identify a second beam of the second subscription, and performing a tune-away operation comprising tuning a radio frequency (RF) resource of the multi-subscription wireless device to the second subscription and configuring spatial filter parameters of an antenna array to communicate via the identified second beam of the second subscription.

    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 hopping design for larger bandwidth allocations in enhanced machine type communications (eMTC). A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving a resource allocation for uplink transmission in at least one subframe. The resource allocation includes a set of allocated subframes and configuration information for frequency hopping. The method includes determining allocated frequency hopped resources, within a system bandwidth, for each subframe of the set of allocated subframes. The method includes including a center resource block (RB) in addition to the determined allocated frequency hopped resources if the determined allocated frequency hopped resources include resources around the center RB. The method includes removing a last RB from the determined allocated frequency hopped resources if the determined allocated frequency hopped resources include resources around the center RB.
