Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems as described herein may be configured to support several service types with different latency, reliability, or throughput rates or standards. One such service type may be referred to as high-reliability, low latency communication (HRLLC). Enhancements to improve HRLLC performance in coexistence with and as a complement to legacy service types, such as LTE are described. These include, for example, downlink and uplink control enhancements, channel state information (CSI) feedback enhancements, physical uplink shared channel (PUSCH) enhancements, and UL power control enhancements to support HRLLC.

Abstract: Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). An example method generally includes identifying a plurality of slots in a subframe, receiving a resource configuration for an uplink channel, wherein the resource configuration is associated with a first slot of the plurality of slots, determining a resource for transmitting the uplink channel in a second slot of the plurality of slots, wherein the resource is determined based on the resource configuration associated with the first slot of the plurality of slots, and transmitting the uplink channel in the second slot using the determined resource.

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: Various aspects described herein relate to receiving wireless communications from an access point, determining resources of the wireless communications associated with a search space for control information in the received wireless communications, and performing one or more of a set of blind decodes over the search space to decode at least low latency control information associated with a low latency communication technology, wherein the low latency communication technology utilizes a transmission time interval (TTI) having a duration that is less than a subframe of a legacy communication technology.

Abstract: Certain aspects of the present disclosure provide techniques for co-existence of reliable low-latency and other services in a wireless network. According to certain aspects, a method of wireless communication by a base station is provided. The method generally includes reserving a first region of a set of resources to a first user for at least a first uplink transmission related to a first type of service, receiving the first uplink transmission in the reserved first region, and dynamically assigning resources in a second region of the set of resources for at least a second uplink transmission related to the first type of service.

Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

Abstract: Techniques are described for wireless communication. One method includes winning a contention for access to an unlicensed radio frequency spectrum band, transmitting a request message upon winning the contention for access to the unlicensed radio frequency spectrum band, and receiving a response message over the unlicensed radio frequency spectrum band. The request message is transmitted by a user equipment (UE) on an enhanced physical random access channel (ePRACH) or shortened ePRACH (SePRACH), to access a cell that operates in the unlicensed radio frequency spectrum band. The response message is received in response to transmitting the request message, and the request message may be transmitted irrespective of whether a base station has gained access to the unlicensed radio frequency spectrum band. Moreover, system information provides information necessary for the UE to identify which subframe is assigned to random access, and during which first subset of symbols in the subframe the UE shall perform a Listen-Before Talk, LBT, procedure, and only when the spectrum band is considered not to be in use, then perform conventional random access in an ensuing second subset of symbols of the subframe.

Abstract: Techniques are described for wireless communication. A first method includes receiving from a base station an indication of a set of one or more uplink interlaces of an unlicensed radio frequency spectrum band allocated for a sounding reference signal, and transmitting the sounding reference signal for a user equipment (UE) over the indicated set of one or more uplink interlaces of the unlicensed radio frequency spectrum band. A second method includes receiving an indication of an interlace of an unlicensed radio frequency spectrum band allocated for a physical uplink control channel (PUCCH) transmission, and transmitting a scheduling request and a buffer status report over the indicated interlace.

Abstract: The present disclosure, for example, relates to one or more techniques for indicating a frame format for transmissions using unlicensed radio frequency spectrum bands. A UE may receive, from a base station, a frame format indicator associated with a transmission opportunity for transmissions in an unlicensed radio frequency spectrum band. The UE may determine a time-division duplexing (TDD) configuration for the transmission opportunity based at least in part on the frame format indicator.
