Abstract: In accordance with one or more embodiments and corresponding disclosure thereof, various aspects are described in connection with providing shared scheduling request (SR) resources to devices for transmitting SRs. Identifiers related to the shared SR resources can be signaled to the devices along with indications of the shared SR resources in given time durations. Thus, devices can transmit an SR over shared SR resources related to one or more received identifiers for obtaining an uplink grant. This can decrease delay associated with receiving uplink grants since the device need not wait for dedicated SR resources before transmitting the SR. In addition, overhead can be decreased on control channels, as compared to signaling dedicated SR resources and/or uplink grants. Moreover, identifiers related to SR resources can correspond to a grouping of devices, such that a device can transmit over shared SR resources related to a group including the device.

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: Multiple base stations, which may be controlled by different network operators, share a transmission medium to serve multiple user equipment (UE). A first base station determines that the shared communication medium is free. The first base station transmits, during a first medium access slot on the shared communication medium, a pre-grant for a first UE associated with the first base station. The first UE transmits a response message during the first medium access slot. Optionally, a second base station may join the transmission by transmitting a pre-grant to a second UE during a subsequent medium access slot.

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: Certain aspects of the present disclosure provide techniques for MCS and/or rank selection for UE jointly served by BSs in a CoMP cluster. As described herein, MCS and/or rank selection may be based, at least in part, on the inter-cluster interference and intra-cluster interference experienced by the UE. According to aspects, a CoMP scheduler may assign a UE served by BSs in a CoMP cluster to one of a first group of UEs or a second group of UEs based, at least in part, on inter-cluster and intra-cluster interference experienced by the UE. The scheduler may assign at least one of a MCS or rank selection to the UE based, at least in part, on the assigned group. The scheduler may provide an indication, to one or more BSs in the CoMP cluster, of the at least one MCS or rank selection assigned to the UE.

Abstract: Certain aspects of the present disclosure generally relate to downlink (DL) based and uplink (UL) based positioning reference signal (PRS) techniques that may help facilitate positioning procedures in systems deploying narrowband devices, such as narrowband Internet of Things (NB-IoT) devices. An exemplary method that may be performed by a node includes monitoring for positioning reference signals (PRS) transmitted from one or more base stations within a narrowband region of a wider system bandwidth, wherein tones of the PRS are repeated across at least one of multiple symbols within a same subframe, or multiple consecutive subframes, and estimating timing from the one or more base stations based on the PRS.
