name: PPW
full_form: PRS Processing Window
context: The requirements for RSTD, PRS-RSRP, UE Rx-Tx time difference, and PRS-RSRPP measurement without measurement gaps specified in clauses 9.9.2.7, 9.9.3.6, 9.9.4.6 and 9.9.6.6 shall apply provided that: Positioning frequency layer to be measured is within an active BWP, UE is configured with PPW, and the PPW for the active BWP containing the positioning frequency layer to be measured is activated, No active BWP switching occurs during the measurement period specified in clauses 9.9.2.7, 9.9.3.6, 9.9.4.6 and 9.9.6.6, PRS is within PPW and does not overlap with other signals/channels of higher priority, - for PPW type 1A/1B, the PPW does not overlap with any symbol for SSB-based RLM/BFD/CBD/L1-RSRP/L1-SINR measurement on any CC or for SSB based RRM measurement on any MOs that are measured outside measurement gaps, - for PPW type 2, PRS does not overlap with any symbol for SSB-based RLM/BFD/CBD/L1-RSRP/L1-SINR measurement on any CC or for SSB based RRM measurement on any MOs that are
description: PRS Processing Window (PPW) is a parameter related to the configuration and activation of a time window for Positioning Reference Signal (PRS) measurements in 5G networks. It ensures gapless measurement by specifying conditions under which PRS can be measured without interruptions.
explanation: The context from 3GPP TS 38.133 highlights PPW as a critical parameter for ensuring accurate and uninterrupted PRS measurements, making it a key attribute for network operation.
