name: UTW
full_form: Uplink Time Window
context: SRS for positioning Tx frequency hopping can be supported for UE in RRC_CONNECTED and RRC_INACTIVE. The UE can be configured with UTW during which the UE is allowed to transmit SRS for positioning Tx frequency hopping. RRC configures the following parameters for the UTW for SRS for positioning Tx frequency hopping: - utw-SlotPeriodicity: Periodicity of the UTW in slot; - utw-SlotOffset: Offset of the beginning of the UTW with respect to the beginning of the UTW periodicity in time domain in slot; - uplinkTimeWindowTimer: Time duration when the UE performs SRS transmission for positioning Tx frequency hopping. When UTW is configured, the MAC entity shall start the uplinkTimeWindowTimer in the first symbol of the slot that the following condition is satisfied CURRENT_slot modulo (utw-SlotPeriodicity) = utw-SlotOffset where CURRENT_slot = [(SFN Ã numberOfSlotsPerFrame) + slot number in the frame] and numberOfSlotsPerFrame refers to the number of consecutive slots per frame as specified in
description: UTW (Uplink Time Window) is a parameter that defines the time window during which the UE is allowed to transmit SRS for positioning Tx frequency hopping. It is configured by RRC and includes parameters such as utw-SlotPeriodicity, utw-SlotOffset, and uplinkTimeWindowTimer.
explanation: The context explicitly mentions UTW as a configurable parameter for SRS transmission, highlighting its role in defining the time window for UE transmission. This classification is justified by the detailed description of UTW parameters and their configuration by RRC.
