Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a scheduling indicator on a first instance of a control channel. The wireless device may determine that a data transmission is scheduled for the wireless device based at least in part on the received scheduling indicator. The wireless device may identify a first frequency band associated with the data transmission and a second frequency band associated with a second instance of the control channel. The wireless device may identify a third frequency band to monitor based at least in part on the first and second frequency bands and a bandwidth capability of the wireless device. The third frequency band includes the first frequency band. The third frequency band comprises an associated bandwidth that is based at least in part on the bandwidth capability of the wireless device.

Abstract: A UE may determine a frame structure for narrowband communications, the frame structure corresponding to one frame structure from a group of TDD frame structures of different downlink and uplink subframe configurations. The UE receives configuration information indicating a first carrier to monitor for a BCH and/or a SIB1. Then, the UE receives a PSS, an SSS, and the BCH and/or the SIB1 using the frame structure determined for the narrowband communications. The first carrier that is used to receive the BCH and/or the SIB1 may be different from a second carrier used to receive one or more of the PSS or the SSS.

Abstract: Wireless communications systems and methods related to bandwidth part (BWP) switching after data communication are provided. A user equipment (UE) receives, from a base station (BS) in a first bandwidth part (BWP), one or more data bursts and BWP switching information. The UE switches from the first BWP to a second BWP based on the BWP switching information after receiving the one or more data bursts. The UE communicates, with the BS, a communication in the second BWP after the switching.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a narrowband TDD frame structure of a group of narrowband TDD frame structures for narrowband communications. The apparatus may transmit a series of repetitions of a narrowband physical downlink channel using the narrowband TDD frame structure. In one aspect, a first portion of repetitions from the series of repetitions may be transmitted in one or more first sets of downlink subframes using a first scrambling sequence. In one aspect, a second portion of repetitions from the series of repetitions may be transmitted in one or more second sets of downlink subframes using a second scrambling sequence.

Abstract: There is a need to support narrowband TDD frame structure for narrowband communications. The present disclosure provides a solution by supporting one or more narrowband TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine to transmit a narrowband physical downlink channel in a subframe in a narrowband TDD frame structure of a plurality of narrowband TDD frame structures for narrowband communications. In addition, the apparatus may determine whether the subframe is a special subframe or a downlink subframe when the narrowband TDD frame structure includes one or more special subframes. Further, the apparatus may determine how to transmit a narrowband physical downlink channel based on the determination whether the subframe is a special subframe or a downlink subframe. Additionally, the apparatus may transmit the narrowband physical downlink channel.

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: Various features related to frequency hopping for broadcast/multicast transmissions for narrow band devices are described. To exploit frequency diversity, multicast transmissions may be frequency hopped. In an aspect, a UE maybe configured to receive a signal, e.g., from a base station, including at least one of a first hopping indicator indicating whether frequency hopping is enabled for a multicast control channel or a second hopping indicator indicating whether frequency hopping is enabled for a multicast traffic channel, and determine whether frequency hopping is enabled for the at least one of the multicast control or traffic channel based on the received signal. The UE may further determine at least one hopping pattern for receiving multicast transmissions in the at least one of the multicast control channel or the multicast traffic channel when the frequency hopping is enabled, and receive the multicast transmissions based on the determined at least one hopping pattern.
