Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may update a noise estimation (e.g., a noise covariance matrix, a log likelihood ratio (LLR) scaling, or both) for communications with a serving base station to account for interference from a neighboring base station operating according to a different radio access technology (RAT). For example, the UE may identify a transmission status of a base station operating according to a first RAT, such as long term evolution (LTE), that shares a radio frequency spectrum with a serving base station operating according to a second RAT, such as new radio (NR). The UE may measure the interference from the LTE base station and may update a noise estimation according to the measured interference. The UE and the serving base station may communicate based on the updated noise estimation.

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: 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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment. UE (115-a), may perform a cell measurement for at least some of a set of cells while operating in a connected mode. The UE may determine a subset of cells of the set of cells based on one or more of the cell measurement, cell-specific information (210), or UE-preferred cell information (215). The cell-specific information may include one or more respective cell parameters associated with at least some if not each cell of the subset of cells. The UE-preferred cell information may include one or more respective preferred cell parameters. The UE may transmit a cell measurement report (205) including an indication of one or more cells of the subset of cells based on the one or more cells of the subset of cells satisfying one or more cell measurement report criteria.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes monitoring a set of master information block broadcasts from a base station to obtain a first set of samples associated with a first prior target transmission time interval (TTI) and a second set of samples associated with a current TTI, identifying a payload change in the master information block broadcasts between the first set of one or more prior TTIs and the current TTI based on a comparison between the first set of samples and the second set of samples, modifying the first set of samples based on the identified payload change, and decoding a master information block based on a combination of the modified first set of samples and the second set of samples. Other aspects, embodiments, and features are also claimed and described.

Abstract: Techniques and apparatus for transmission and reception with partial allocation in orthogonal frequency division multiple access (OFDMA)/single-carrier frequency division multiple access (SC-FDMA) systems are provided. One technique includes determining first parameter(s) to apply to transmission/receive processing of a signal, based in part on a resource allocation for the signal. The resource allocation is partitioned out of a larger system bandwidth. Second parameter(s) to apply to the transmission/receive processing are determined based at least in part on the first parameter(s). Transmission/receive processing of the signal is performed in accordance with the first and second parameters.

Abstract: Aspects of the present disclosure relate to methods and apparatus for optimizing real time services (e.g., such as a voice over Long Term Evolution (LTE) (VoLTE)) for devices with limited communications resources, such as machine type communication (MTC) devices and enhanced MTC (eMTC) devices. In one aspect, a UE determines a first configuration of subframes within at least one radio frame available for the UE and other UEs to use for bundled communications with a BS. The UE receives an indication of one or more subframes within the at least one radio frame that are unavailable for bundled uplink transmissions, and determines a second configuration of subframes to use for bundled communications based on the indication. The UE overrides the first configuration of subframes with the second configuration of subframes, and communicates with the BS using the second configuration of subframes. Numerous other aspects are provided.
