Abstract
Various aspects described herein relate to reducing transmission latency in unlicensed spectrum. These latency reduction techniques include enabling ultra low latency (ULL) traffic to gain fast channel access. These latency reduction techniques further include updating a size of a contention window for channel access. In addition, these latency reduction techniques include enhancing CPDCCH-based signaling to accommodate the ULL frame structure. Further, these latency reduction techniques include providing robust operation against bursty interference for ULL transmissions. Moreover, these techniques include managing DRX for ULL. Additionally, these latency reduction techniques include joint scheduling of different TTI durations. These latency reduction techniques further include updating SRS transmission opportunities. In addition, these latency reduction techniques include reducing latency associated with PRACH transmissions. Further, these latency reduction techniques include reducing ULL transmission delays by either ignoring or cancelling scheduled uplink (e.g., LTE) transmissions.
