AI Technical Summary
Technical Problem
The existing wireless communication systems have problems of delay and inefficiency when coordinating the timeline of channel status information reporting of side link channels.
Method used
By introducing a new time requirement Z in the wireless communication system, this requirement defines the time required for the UE to aggregate and send side link CSI reports and starts after the UE receives the CSI report. Meanwhile, the base station can configure a CSI reception time window for the UE to avoid delays caused by waiting for unreceived CSI reports.
Benefits of technology
Effectively coordinate the CSI reporting timeline, reduce the time UE waits for CSI reporting, and improve the efficiency and reliability of channel status information reporting.

Abstract
Methods, systems, and devices for wireless communication are described. In some systems, a base station may use control information to trigger a CSI reporting process to irregularly update channel state information (CSI) on a sidelink between a first user equipment (UE) and one or more second UEs. The aperiodic CSI process may include the base station sending timing requirements and control information to the UE. Control information including a CSI request may be received and decoded at a UE. In accordance with the CSI request, the first UE may transmit a reference signal on a sidelink for measurement by the second UE. The UE (s) may generate and transmit CSI reports to the first UE on a sidelink, and the first UE may aggregate the received CSI reports (s) and transmit them to the base station within a time period specified by timing requirements received in the control information.
