Embodiment 1

[0267] Embodiment 1: A method of wireless communication by a user equipment (UE), comprising: receiving a CSI reporting configuration for full-duplex channel state information (CSI) reporting; monitoring a CSI reference based at least in part on the CSI reporting configuration signal; and transmitting a full-duplex CSI report including uplink bandwidth information based at least in part on the monitoring.

Embodiment 2

[0268] Embodiment 2: The method of embodiment 1, wherein sending a full-duplex CSI report comprises sending a full-duplex CSI report including the uplink bandwidth information including channel state information indicative of a plurality of different uplink bandwidths.

Embodiment 3

[0269] Embodiment 3: the method according to embodiment 1 or embodiment 2, wherein receiving a CSI report configuration includes: receiving a CSI report configuration indicating an uplink bandwidth, wherein the uplink bandwidth information indicates CSI of the uplink bandwidth.

Abstract

Methods, systems, and devices for wireless communications are described. A full duplex user equipment (UE) may provide a channel state information (CSI) report to a base station to enable the base station to schedule simultaneous the uplink and downlink communications for the full duplex UE. For example, the base station may transmit a CSI report configuration to the UE that indicates for the UE to report a full duplex CSI. In some cases, the CSI report configuration may include the UE to report CSI under a full duplex mode with or without an indication of an uplink bandwidth. Accordingly, the UE may calculate and report the self-full duplex mode CSI to the base station according to the received configuration. The base station may then determine a radio resource allocation and transport format for downlink data transfer and for uplink data transfer under the full duplex mode.

Description

[0001] cross reference [0002] This patent application requires the PCT entitled "CSI REPORT RELATED TO UL TRANSMISSION BANDWIDTH BY FULL DUPLEX CAPABLE UE" filed by HUANG et al. on June 14, 2019 The benefit of Application No. PCT / CN2019 / 091244, which is assigned to the assignee of the present application. technical field [0003] The following relates generally to wireless communications, and more specifically to channel state information (CSI) reporting related to the uplink (UL) transmission bandwidth of a full-duplex capable user equipment (UE). 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 so on. These systems may be able to support communication with multiple users by sharing available system resources (eg, time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems such as ...
