Abstract: Methods and apparatuses for transmitting and detecting channel reservation preamble in a NR shared spectrum are described. An aspect may include determining whether a first reservation preamble of a first operator is received on a first time slot of multiple time slots of a downlink channel from a first network entity, and transmitting a second reservation preamble of the first operator on an uplink channel to the second network entity. Another aspect may include generating a first reservation preamble of a first operator based on at least one of a compressed representation in a signal space, a basis function of the signal space, or a CAZAC sequences; and transmitting, on a first times lot of multiple time slots of a downlink channel, the first reservation preamble of the first operator to at least a UE. In another aspect, the SFN transmission of the first and second reservation preambles, and the low latency detection methods of the reservation preambles have been disclosed.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation, which can be used for stand-alone/inband/ guard-band deployment. An example method is provided for operations which may be performed by a base station (BS). The example method generally includes generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, generating a secondary synchronization signal (SSS) based on a second code sequence over a second number of symbols within one or more subframes, and transmitting the PSS and the SSS in the first and second subframes to a first type of a user equipment (UE) that communicates on one or more narrowband regions of wider system bandwidth.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an uplink/downlink (UL/DL) configuration that defines subframe configuration options for each subframe of a frame. For example, the UL/DL configuration may establish parameters for time division duplexing (TDD) operation between a base station and a user equipment (UE). The wireless device (e.g., the UE or base station) may determine a constraint for a subframe of the frame based on the UL/DL configuration and then determine an adaptive subframe configuration based on the constraint. The adaptive subframe configuration may include one or several downlink symbol periods and one or several uplink symbol periods. The wireless device may then communicate during the subframe according to the adaptive subframe configuration rather than the original UL/DL configuration; and, because the adaptive subframe may be constrained by the identified UL/DL configuration, the communication during the subframe may avoid disruption to UEs.

Abstract: RESUMEN Los aspectos de la presente revelación proporcionan técnicas para el diseño de señales de sincronización para una operación de banda estrecha, que se puede utilizar para despliegue autónomo/en banda/de banda de guarda. Se proporciona un método representativo para las operaciones que pueden ser llevadas a cabo por una estación base (BS). El método representativo por lo general incluye la generación de una señal de sincronización primaria (PSS) que utiliza una primera secuencia de código y un código de cubierta aplicado a la primera secuencia de código a través de un primer número de símbolos dentro de una o más subtramas, la generación de una señal de sincronización secundaria (SSS) con base en una segunda secuencia de código a través de un segundo número de símbolos dentro de una o más subtramas, y la transmisión de la PSS y la SSS en la primera y la segunda subtramas a un primer tipo de un equipo de usuario (UE) que se comunica en una o más regiones de banda estrecha de ancho de banda de sistema más amplio.

Abstract: Aspects of the present disclosure provide techniques and apparatus for performing paging and/or random access procedures with multiple physical resource blocks (PRBs) for narrowband (NB) internet-of-things (IoT). In one aspect, a method is provided which may be performed by a base station. The method generally includes determining a first set of resources and a second set of resources available for narrowband communications with one or more first user equipments (UEs) and one or more second UEs. The method also includes allocating the first and second set of resources to one or more of the first UEs and the second UEs based at least in part on a type of the first UEs and a type of the second UEs. The method further includes signaling an indication of the allocation.

Abstract: Methods, systems, and devices for wireless communication are described that may perform dual stage channel interleaving in which code blocks are interleaved at the code block level and at a symbol level. The interleaved code block data may provide time diversity for the code block data, and the interleaved symbol data may provide frequency diversity for the code block data, thus helping to mitigate narrowband and/or bursty interference. The interleaving within the code block and interleaving within the symbols, in some examples, may allow pipelined implementation of decoding of the code blocks at the receiver, for faster processing. In some cases, systematic data and parity data may be interleaved within the code block data to provide a uniform distribution of the systematic data in time within the code block.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a narrowband (e.g., a single carrier, anchor carrier, etc.) for a control message that includes a grant for downlink data transmissions. The narrowband containing the control message may be a portion of a system bandwidth. The UE may then monitor a wideband (e.g., all or multiple carriers of the system bandwidth) for data according to the control message. Monitoring the wideband may include additional or alternate circuitry being powered (e.g., receiver circuit switching) to enable reception on an increased range of frequency spectrum. In some examples, a gap or narrowband data transmission may be scheduled between the control message and the grant to allow grant processing and receiver circuitry switching at the UE. In some cases, the control message and data transmission may be received in the same or different transmission time intervals (TTIs).
