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: The present disclosure may support dedicated scheduling request resources in a NPUSCH format resource structure, a NPRACH, and/or an ACK/NACK transmission associated with a downlink transmission received at the UE. In addition, the present disclosure may provide various techniques to mitigate collisions between scheduling requests transmitted by a UE, uplink transmissions sent by different UEs, and/or downlink transmissions sent by a base station. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive one or more downlink transmissions from a base station. The apparatus may determine to transmit an uplink transmission to the base station. The apparatus transmit, to the base station, a scheduling request for the uplink transmission with an ACK/NACK associated with the one or more downlink transmissions using a narrowband NPUSCH format resource structure.

Abstract: In order to more efficiently use system resources and to reduce power usage, a narrowband apparatus may determine a set of monitored resource blocks (RBs) on a subframe for monitoring for CRS from a base station may monitor for the CRS from the base station on the subframe based on the set of monitored RBs. The base station may determine a bandwidth for transmitting the CRS to a user equipment, wherein the bandwidth is less than a system bandwidth and may transmit the CRS to the UE using the determined bandwidth, wherein the UE monitors for the CRS on a set of monitored RBs. The set of monitored RBs may include RBs allocated for a PDCCH search space, PDCCH and/or PDSCH transmissions and may further include RBs M subframes after and/or N subframes before the monitored RBs. The set of monitored RBs may include X RBs around a PDCCH search space and/or PDSCH.

Abstract: Techniques described herein permit a narrowband Internet of Things (NB-IoT) user equipment (UE) to combine narrowband reference signals (NRS) with other signals, which the NB-IoT UE already receives, to improve measurement accuracy. The UE may report whether the UE is capable of combining the NRS with another signal to determine a combined signal quality parameter, and may report the combined signal quality parameter to a base station.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In addition, the apparatus may determine a first set of subframes in the narrowband TDD frame structure used for transmitting a downlink control channel to a UE. In one aspect, a last subframe in the first set of subframes may be subframe n. Further, the apparatus may determine a second set of subframes in the narrowband TDD frame structure used for transmitting a downlink data channel to the UE. In certain aspects, a first subframe in the second set of subframes may be delayed based on k0 number of subframes after the subframe n. In certain other aspects, a last subframe in the second set of subframes may be subframe n+k0+x. Additionally, the apparatus may signal first information associated with the k0 number of subframes to the UE in a first delay field in a DCI transmission.

Abstract: A method of wireless communication includes determining a set of subframes with a reduced likelihood of being received as uplink transmissions of a first user equipment (UE). The method also includes scheduling uplink transmissions of the first UE by scheduling uplink control information (UCI) on subframes other than the determined set of subframes.
