Abstract:
Aspects directed towards a cell-specific configuration for sounding transmissions and measurements are disclosed. In one example, scheduled entities served by a scheduling entity are identified and a cell-specific sounding pattern configuration uniformly applicable to each of the scheduled entities is generated such that the cell-specific sounding pattern configuration has a different pattern than a cell-specific sounding pattern configuration associated with at least one other cell. The cell-specific sounding pattern configuration is then transmitted to each of the scheduled entities to facilitate an identification of cell-specific resources to use for at least one of a sounding transmission or a sounding measurement. In another example, a cell-specific sounding pattern configuration is received and cell-specific resources associated with the cell-specific sounding pattern configuration are identified. At least one of a sounding transmission or a sounding measurement is then configured according to the cell-specific resources associated with the cell-specific sounding pattern configuration.
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). Additionally, certain aspects of the present disclosure provide techniques for managing communications in a wireless communication system, for example, by using enhanced downlink control channels.
Abstract:
Wireless communications systems and methods related to reservation signal transmission and detection for spectrum sharing are provided. A first wireless communication device communicates, with a second wireless communication device, a reservation request (RRQ) signal to reserve a transmission opportunity (TXOP) in a shared spectrum, wherein the shared spectrum is shared by a plurality of network operating entities, and wherein the first wireless communication device and the second wireless communication device are associated with a first network operating entity of the plurality of network operating entities. The first wireless communication device transmits a reservation response (RRS) signal indicating an interference tolerance level of the first wireless communication device.
Abstract:
A network operator may synchronize access for wireless nodes (e.g., base stations) associated with the network operator. However, each network operator of a group of network operators may not synchronize access among the group. A lack of synchronization between network operators intending to utilize shared channels of a wireless communication system may result in a failure to utilize all available network resources. In some aspects, a device associated with a first network operator, of a plurality of network operators, may listen for communications associated with other network operators, of the plurality of network operators in a shared radio frequency spectrum band, during a set of intervals of a transmission opportunity of a channel for which the other network operators have a higher priority, and may communicate, using the channel, with a wireless node associated with the network operator based at least in part on the listening for communications.
Abstract:
Various aspects described herein relate to receiving a first communication over a first set of resources based on a first transmission time interval (TTI), receiving a second communication over a second set of resources based on a second TTI, where the second TTI is smaller than the first TTI, and where the second set of resources overlap the first set of resources defining a common set of resources, and determining whether to prioritize decoding of the first communication over the second communication.
Abstract:
Apparatus and methods, in one or more aspect, provide feedback with respect to downlink grant feedback communications received by a user equipment (UE). The apparatus and methods monitor for signals from a network entity on one or more channels, and determine, based on the monitoring, whether one or more grants are received and whether UE data is received on the one or more channels. Further, the apparatus and methods generate a feedback indication having a feedback value determined according to a feedback rule and based on whether the one or more grants and the UE data are received. Additionally, the apparatus and methods transmit the feedback indication to the network entity on a resource determined according to the feedback rule and based on whether the one or more grants and the UE data are received.
Abstract:
Techniques for handover procedure management are described herein. An example method may include monitoring, at a target base station, reference signal information associated with a UE based on a reference signal configuration of the UE received by the target base station from a source base station. Additionally, the example method may include estimating, at the target base station, timing information for the UE based on the reference signal information. Further, the example method may include transmitting, by the target base station, the timing information to the source base station, where the source base station provides the timing information to the UE for handover to the target base station.
Abstract:
An example data structure for managing user equipment communications in a wireless communications system is presented, as well as methods and apparatuses configured to implement the data structure. For instance, the data structure may include a downlink subframe comprising two slots and including one or more quick downlink channels having a single-slot transmission time interval. In addition, the example data structure may include one or more resource element blocks each comprising one or more resource elements into which a frequency bandwidth is divided within one or both of the two slots, wherein each of the one or more resource element blocks comprises a control channel region or a data channel region. Furthermore, the example data structure may include one or more resource grants, located within one or more control channel regions, for one or more user equipment served by the one or more quick downlink channels.

Abstract:
Certain aspects of the present disclosure relate to allocating transmission power in multiple connectivity wireless networks. A device can establish a first connection with a first primary cell in a first cell group as well as a second connection with a second primary cell in a second cell group. The device can determine whether to prioritize a first communication over the first connection or a second communication over the second connection, wherein the first communication and the second communication are scheduled for concurrent transmission. In addition, the device can transmit at least one of the first communication over the first connection or the second communication over the second connection in a transmission time interval based at least in part on determining whether to prioritize the first communication or the second communication.
