Title: LOW LATENCY POINT TO MULTIPOINT COMMUNICATION TECHNIQUES
Abstract:
Techniques for low latency point to multipoint (PTM) communications in a system supporting communications using multiple different transmission time interval (TTI) durations are provided. The low latency PTM communications may be supported by one or more physical channels that support PTM communications at shortened TTI durations. In some examples, a base station may allocate, in a PTM traffic channel, a first set of resources for PTM transmissions with a first user equipment (UE) and a second UE, and may allocate a second set of resources (e.g., in a physical downlink shared channel (PDSCH)) for unicast transmissions to the first UE. The PTM transmissions may be transmitted using TTIs configured with durations shorter than TTIs used for transmitting unicast transmissions. Different sets of PTM resources may be allocated for different PTM transmissions having different TTI durations.
