DL Assignment reception中的NDI问题 协议中说: Downlink assignments transmitted on the PDCCH indicate if there is a transmission on the DL-SCH for a particular UE and provide the relevant HARQ information. When the UE has a C-RNTI, Semi-Persistent Scheduling C-RNTI, or Temporary C-RNTI, the UE shall for each TTI during which it monitors PDCCH: - if a downlink assignment for this TTI has been received on the PDCCH for the UE’s C-RNTI, or Temporary C RNTI: - if this is the first downlink assignment for this Temporary C-RNTI: - consider the NDI to have been toggled. - if the downlink assignment is for UE’s C-RNTI and if the previous downlink assignment indicated to the HARQ entity of the same HARQ process was either a downlink assignment received for the UE’s Semi-Persistent Scheduling C-RNTI or a configured downlink assignment: - consider the NDI to have been toggled regardless of the value of the NDI. 这边NDI认为翻转有什么用啊,NDI初始值是0还是1,为什么最后一句说忽略NDI的值,认为NDI值翻转了。这段伪代码实在看不太懂,请tom老师分析指导下啊,谢谢啦! |
