Problems solved by technology

Dynamic TDD (which is similar to Enhanced Interference Mitigation and Traffic Adaptation (eIMTA) in LTE) can provide additional flexibility for configuring resources, but may be limited by cross-link interference (CLI) , where a device served by one base station may send uplink communications that interfere with downlink communications from another base station (to another device), and / or where a base station may send messages from another base station to another device Interfering downlink communication (to the device) caused by the uplink communication of the base station

Embodiment Construction

[0025] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It will be apparent, however, that such aspects may be practiced without these specific details.

[0026] The described features generally involve scheduling transmissions of uplink and downlink reference signals on similar resources (eg, in frequency, time, and / or space) to facilitate cross-link interference (CLI) measurement and mitigation. For example, an access point may configure resources on which a user equipment (UE) is to transmit uplink reference signals, wherein the resources may be used at least in part by another access point to transmit downlink reference signals or by Configured as a downlink interference measurement resource (IMR) (and / or configured for another UE to transmit another uplink reference signal). For example, i...

Abstract

Aspects herein describe sending reference signals in wireless communications. An indication of resources on which to transmit an uplink reference signal can be received from an access point, where the resource is at least partially used by another device to transmit a downlink reference signal or a second uplink reference signal. Uplink reference signals may be sent on the resources.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This patent application claims US Non-Provisional Application Serial No. 15 / 981,572, filed May 16, 2018, and entitled "CONFIGURING REFERENCESIGNAL TRANSMISSION IN WIRELESS COMMUNICATIONS," Priority to U.S. Provisional Application No. 62 / 508,125 to SIGNAL TRANSMISSION INWIRELESS COMMUNICATIONS", both of which are assigned to the assignee of the present application, and are expressly incorporated herein by reference for all purposes. technical field [0003] Aspects of the present disclosure relate generally to wireless communication systems, and, more particularly, to configuring resources for transmitting reference signals. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and the like. These systems may be multiple-access systems capable of supporting communication with multiple use...
