Abstract: The present disclosure provides various modifications to existing techniques for transmitting ACK and/or NACK in an narrow band communications system. For example, in a first aspect, an apparatus receives a downlink transmission and transmits a single tone ACK on an ACK channel using time-spreading. In another aspect, an apparatus determines whether an ACK has been received from a UE within a threshold amount of time, and when an ACK has not been received from the UE for at least the threshold amount of time, transmitting an indication to the UE to transmit regarding the ACK

Abstract: Aspects of the present disclosure provide techniques for uplink (UL) data channel design. An example method is provided for operations which may be performed by a first apparatus. The example method generally comprises determining a number of pilot symbols to transmit for one or more slots of a first subframe based, at least in part, on a coverage enhancement (CE) level, and transmitting at least one uplink data channel having the determined number of pilot symbols in the one or more slots of the first subframe.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for implementing a data transmission scheme for Narrow-Band Internet of Things (NB-IoT). A User Equipment (UE) combines pairs of antenna ports to generate at least first and second combined antennas ports. The UE receives reference signals transmitted in a narrow band region of a larger system bandwidth, and for each combined port, adds the references signals received on resource elements (REs) of each of the combined pair of antenna ports. The UE determines channel estimates for each combined antenna port based on the added reference signals for the combined port.

Abstract: A UE in an eDRX cycle may miss an SI change notification because the UE's receiver may be powered down during the entire modification period prior to the SI change. An apparatus for wireless communication at a base station may transmit SI, change the SI during a period of eDRX by a UE, and transmit the changed SI. The apparatus ensures that a UE receives an SI change notification, even when performing eDRX, by transmitting at least one notification associated with the changed SI after the transmission of the changed SI and during a paging occasion for the UE. In another aspect, an apparatus for wireless communication at a UE enters into an eDRX cycle and receives, after an SI change, a notification associated with the SI change.

Abstract: In eMTC, channels may be bundled, using repetitions in multiple subframes. SPS and DRX for eMTC may not accommodate such repetitions, because repetitions for a bundled channel may fall only partially within a DRX ON duration. An apparatus addresses this problem by determining a DRX ON duration, determining a set of subframes carrying a bundled M-PDCCH candidate and determining that the DRX ON duration at least partially overlaps with the set of subframes of the bundled M-PDCCH. The apparatus then refrains from decoding the first bundled M-PDCCH candidate, decodes the first bundled M-PDCCH candidate, or extends the DRX ON duration to include the set of subframes entirely and decoding the first bundled M-PDCCH candidate carried in the set of subframes in the extended DRX ON duration. The apparatus may also determine DRX configuration parameters based on parameters of bundled channels, and handle invalid subframes for an SPS grant.

Abstract: Aspects of the present disclosure provide hybrid automatic repeat request (HARQ) techniques for enhanced machine type communication (eMTC). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE) for determining a HARQ ID. The method generally includes determining a HARQ ID based, at least in part, on a coverage enhancement (CE) level, and performing a HARQ process timeline based, at least in part, on the determined HARQ ID. Another method is provided for determining a subframe to transmit feedback. The method generally includes determining at least one subframe to transmit a physical uplink control channel (PUCCH) to acknowledge one or more downlink transmissions based, at least in part, on availability of uplink subframes following one or more downlink subframes carrying the downlink transmissions to be acknowledged and transmitting the PUCCH in the determined at least one subframe.

An example method generally includes receiving a physical random access channel (PRACH) signal from a first user equipment (UE) on a first narrowband region within a wider system bandwidth and transmitting, in response to the PRACH signal, a random access response (RAR) signal in a first search space in a second narrowband region in at least a first subframe.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit DCIs to a UE to schedule instances of one or more MBS TBs, the multiple instances of the one or more TBs being time-interleaved. For example, the network entity may transmit a first set of DCIs scheduling a first set of instances of a first TB, and a second set of DCIs scheduling a second set of instances of a second TB, where at least one instance of the first set of instances may be interleaved with the second set of instances. In some cases, the first and second set of DCIs may include one DCI to schedule the respective set of instances, or one DCI per instance of the respective set of instances. Additionally, or alternatively, the network entity may indicate one or more parameters to the UE associated with MBS inter-TB time interleaving.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a distributed unit (DU) of a network node associated with a non-terrestrial network (NTN), an uplink transmission, wherein the DU is onboard a satellite and a central unit (CU) of the network node is on ground. The UE may receive, from the DU, a downlink transmission based at least in part on a delayed downlink channel monitoring window, wherein the delayed downlink channel monitoring window is based at least in part on a first time offset and a second time offset, the first time offset is associated with a UE-DU round-trip time (RTT), and the second time offset is associated with a CU-DU RTT. Numerous other aspects are described.
