Title: SYSTEM AND METHOD FOR COEXISTENCE OF LOW LATENCY AND LATENCY TOLERANT COMMUNICATIONS
Abstract:
Systems and methods are provided for transmitting and receiving pre-emption indications. The pre-emption indication is transmitted every K symbols or slots, on a group-common physical downlink control channel. The pre-emption indication is in respect of a group of K symbols or slots preceding a symbol or slot containing the group-common pre-emption indication. The group-common pre-emption indication indicates, for the group of K symbols or slots, which resources are pre-empted. The base station schedules resources for first downlink traffic, and transmits the scheduled first downlink traffic subject to pre-emption, and transmits second downlink traffic by pre-empting resources for the first downlink traffic. On the UE side, the UE receives the pre-emption indication. The UE receives its scheduled traffic taking into account the pre-emption indication.
