Embodiment Construction

[0031] Some embodiments of the invention will now be described in detail, some examples of which are illustrated in the accompanying drawings.

[0032] figure 1 It is a system schematic diagram of a wireless network supporting low-latency and ultra-low-latency communication according to an embodiment of the present invention. The wireless communication system 100 includes one or more wireless networks, each having fixed infrastructure elements, such as receiving wireless communication devices or UEs 102, 103, and 104, to form a geographically distributed wireless network. A base unit may also be called an access point, access terminal, base station, Node B, eNB, or other terminology employed in the art. Each of the receiving UEs 102, 103, and 104 serves a geographic area. Backhaul connections 113 , 114 and 115 connect non-co-located receiving UEs, such as 102 , 103 and 104 . These backhaul connections may or may not be ideal.

Abstract

Apparatus and methods are provided for low latency an ultra-low latency (ULL) communications. In novel aspect, short TTIs are configured for low latency communications. The UE configures one or more downlink short transmission time interval (sTTI) regions over a normal TTI region, decodes one or more low latency control channels, which indicates one or more sTTI regions for one or more UEs, and obtains one or more sTTI regions for the UE based on the decoded low latency control channels. In one embodiment, the location short TTI control channels is determined by detecting a short TTI control message at a beginning of a TTI and obtaining a duration of the short TTI in the detected short TTI control message. In one embodiment, the UE obtains one or more uplink resources, power control and CSI configurations based on corresponding downlink short TTI transmissions according to a mapping rule.

Description

[0001] cross reference [0002] This application claims priority under 35 U.S.C.§119 to U.S. Provisional Application 62 / 317,447, filed April 1, 2016, entitled "system design for low latency communication and ultra-low latency communications," and the above application is incorporated as refer to. technical field [0003] The present invention relates to wireless communication, and more particularly to methods and apparatus for wireless communication system design. Background technique [0004] Mobile network communications continue to grow rapidly, and mobile data services will continue to soar. New data applications and services need to be faster and more efficient, and big data bandwidth applications continue to attract more users. Today, 3G / 4G mobile wireless systems provide connectivity for a wide variety of applications and services. In the next-generation 5G network, it is expected that the latency issue will become one of the Key Performance Indicators (KPI), whic...
