摘要： A method and apparatus for wireless communication in the unlicensed spectrum between an eNB and UEs having different bandwidths, e.g., between a narrowband UE and a wideband eNB. A base station apparatus performs an LBT procedure at a beginning of frames and transmits a plurality of repetitions of a transmission. When the plurality of repetitions span multiple frames and the LBT procedure is not successful for a first frame, the base station drops or postpones at least one repetition in the first frame until a second frame when the LBT procedure is successful. A UE receives the plurality of repetitions and may combine a plurality of repetitions across multiple frames. The UE may determine whether the base station drops the at least one repetition in the first frame or postpones the at least one repetition in the first frame until a second frame.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) operating in an unlicensed radio frequency spectrum band may transmit autonomously (e.g., without a resource assignment) to a base station. For example, a base station may indicate a periodic resource allocation to the UE using radio resource control (RRC) messaging. The UE may then perfonn a listen-before talk (LBT) procedure and transmit physical uplink control channel (PUCCH) or other messages using the periodic resource allocation. Thus, the UE may transmit uplink messages without receiving an assignment of uplink resources from the base station. The UE may transmit identification and synchronization information in a scheduling request (SR) resource of the autonomous PUCCH. For example, the UE may indicate a start time and duration of an autonomous uplink transmit opportunity (TxOP) using resources designated for SR transmission.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) and base station may communicate using narrow band internet of things (NB-IoT) techniques or enhanced machine type communication (eMTC) in unlicensed spectrum. The UE may be an eMTC device or another device capable of communication without user direction. The UE may identify a geographic region and select a communication mode that is consistent with regulatory restrictions in that region. For example, in some cases, the communication mode may be based on using time division duplexing (TDD), using frequency hopping, or performing a listen-before-talk (LBT) procedure at the base station. A frame structure for TDD may include LBT subframes, uplink portions, downlink portions, and special subframes for switching. The base station may perform LBT procedures in the LBT subframes. If frequency hopping is enabled, a configurable number of TDD frames may be grouped into a hopping frame block.

摘要： 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.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for wireless communication are provided. The apparatus may be a base station. The apparatus may transmit an uplink grant to a UE during a first transmit opportunity. The apparatus may signal, during a second transmit opportunity, a grant trigger to the UE to trigger operations associated with the uplink grant that are uncompleted after the first transmit opportunity. The grant trigger may be associated with a set of UEs that includes the UE. The set of UEs may be a subset of the UEs having pending transmissions. The apparatus may instruct the UE regarding whether to keep or discard resources granted by the uplink grant when the UE switches to a different beam during or prior to the second transmit opportunity.

摘要： Methods, systems, and devices for wireless communication are described. A base station within a wireless system may determine a measurement scheme or uplink mode and then transmit an indication of the scheme or uplink mode to an associated user equipment (UE). The base station may, for example, identify a set of hidden nodes for the UE and configure the UE for autonomous or grant-based uplink transmissions accordingly. The UE may identify a signal strength of neighboring nodes, which the UE may communicated to the base station for identification of hidden nodes. In some examples, the UE may be configured with an autonomous uplink, which may support unscheduled uplink communications, when a base station determines that operating in the autonomous uplink mode would provide a benefit for the UE—e.g., a benefit for UE operation in view of hidden nodes with which the UE may contend.

摘要： Methods, systems, and devices for wireless communications are described. The method may include determining multiple transmission beams (e.g., beamformed directional beams) for transmission of an opportunistic or multi-beam discovery reference signal (DRS) over a shared radio frequency spectrum band. A base station may perform a listen before talk (LBT) procedure for the multiple DRS transmission beams, and transmit, based on the LBT procedure, the DRS over the shared radio frequency spectrum band using a set of the multiple transmission beams (e.g., a set that cleared an LBT procedure). In some cases, the LBT may be performed for each transmission beam, or for a union of all transmission beams, associated with the DRS transmission beams. Alternatively, the base station may determine a contention exempt transmission (CET) period for the shared spectrum band and transmit the DRS using the multiple transmission beams during CET period.

摘要： 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.
