Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a neighbor cell and report the result to a serving base station. Based on the report, the serving base station may identify an estimated discovery reference signal (DRS) transmission window of the neighbor cell. In some cases, the UE may estimate and report parameters of the neighbor DRS transmission window, and in other cases, the UE may make a measurement report and the base station may infer DRS transmission window parameters. The base station may then provide the UE with a DRS measurement timing configuration (DMTC) based on the estimated parameters of the neighbor cell so that the UE may monitor the neighbor cell and the serving cell in an efficient manner. For example, the UE may conserve battery life by refraining from monitoring DRS during periods when a DRS transmission is not likely.

Abstract: Methods, systems, and devices for wireless communication are described. Various autonomous uplink control channel configurations may be used for unscheduled uplink transmissions. For example, a user equipment (UE) may initiate an unscheduled uplink transmission and may identify an autonomous uplink control channel configuration for the uplink transmission. The UE may transmit control information and data during an initial transmission time interval of a transmission opportunity according to the control channel configuration, where the control channel configuration control may include a number of different waveforms and payload configurations. For example, an autonomous uplink control channel configuration may include control information frequency division multiplexed or time division multiplexed with data and transmitted in one or more frequency interlaces. In some cases, the control channel configuration may include a symbol period for a clear-to-send signal, and one or more symbol periods used a guard period before the data transmission.

Abstract: Un método (1400) de comunicación inalámbrica llevado a cabo por un equipo de usuario, UE, en un sistema 3GPP, que comprende: recibir (1405) una transmisión de datos de enlace descendente utilizando recursos de una banda de espectro de radiofrecuencia, RF, compartido durante una primera oportunidad de transmisión, TxOP, desde una estación base; transmitir (1410) una retroalimentación de solicitud de repetición automática híbrida, HARQ, en respuesta a la transmisión de datos de enlace descendente durante la primera TxOP o una segunda TxOP y almacenar la retroalimentación de HARQ transmitida en un búfer del UE; recibir una solicitud de la estación base para retransmitir un subconjunto de retroalimentación de HARQ previamente transmitida; retransmitir la retroalimentación de HARQ solicitada; recibir una indicación para borrar el búfer después de la retransmisión de la retroalimentación de HARQ solicitada, donde la indicación identifica la retroalimentación de HARQ a vaciarse del búfer; determinar (1415) el vaciado del búfer de la retroalimentación de HARQ durante la segunda TxOP o una tercera TxOP; y vaciar (1420) la retroalimentación de HARQ del búfer.

Abstract: Methods, systems, and devices for wireless communication are described. A downlink control message type used for triggering uplink transmissions may convey additional information, including timing for uplink transmissions. The type or format of the control channel (e.g., physical downlink control channel (PDCCH) type or format) used to trigger an uplink transmission may also indicate a starting time or a time period, or both for the uplink transmission. In some cases, downlink control information (DCI) may indicate the function of a downlink control message that includes the DCI. Additionally, system information identified in a downlink control message may be used to determine a subframe length which, in some examples, may be used to determine whether or how long to monitor a discovery reference signal (DRS) subframe.

Abstract: Certain aspects of the present disclosure relate to a methods and apparatus for wireless communication. In one aspect, a method of wireless communication comprises receiving, by a long term evolution unlicensed (LTE-U) device, a plurality of signals from an access point on an unlicensed communication spectrum. The method further comprises determining, by the device, whether a signal of the plurality of signals comprises a discovery signal. The method further comprises monitoring a radio link based on, the signal if the signal is determined to comprise the discovery signal.

Abstract: Techniques for performing listen before talk (LBT) channel contention procedures in a shared radio frequency spectrum band are provided. The LBT techniques may include a shortened LBT procedure that may be selected if a base station has reserved a shared channel for a duration of expected user equipment (UE) uplink transmissions, and a full LBT procedure that may be selected if the base station has not reserved the channel for the duration of expected UE uplink transmissions. The shortened LBT procedure may include detecting energy levels of the channel for a relatively short time period relative to the full LBT procedure. The shortened LBT procedure may be selected if a time period between a UE receiving a grant of uplink resources and the beginning of the uplink resources is less than a threshold time value.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a configuration for enhanced paging to a UE being served by a cell over a shared frequency band. The enhanced paging may include multiple paging intervals for each paging cycle. The UE may enable reception for a paging interval and determine whether the UE receives a downlink transmission. The UE may lengthen a paging interval or enable reception during a second paging interval based in part on determining whether the UE receives a downlink transmission. In some examples, the UE may receive a paging queue status indication indicating that paging information will be transmitted during a paging interval or a later interval, or indicating that no paging information is present at a serving cell.

Abstract: Methods, systems, and devices for wireless communication are described. Resources for narrowband communication in an unlicensed radio frequency spectrum band may be configured and allocated based on resource availability, regulatory constraints, and device capability or category. A narrowband wireless device, such as a machine type communication device or other relatively low complexity device, may communicate using one or more narrowband carriers, which may occupy between one tone and multiple resource blocks in an unlicensed spectrum band (e.g., any number of resources between one (1) tone and multiple resource blocks (RBs)). Different device types may thus be configured differently as they move between geographic regions. The base station may then communicate with the narrowband mobile device based on the resource allocation and the carrier configuration.
