1. A method for configuring a transmission time interval (TTI) in a base station of a mobile communication system, comprising:
- configuring at least one LL (low latency) TTI, with a length of at least one transmission symbol and shorter than a length of one subframe, in a subframe including a plurality of transmission symbols;
transmitting LL (low latency) TTI related information using a control format indicator (CFI) of N bits larger than 2 bits of a physical control format indicator channel (PCFICH) transmitted at a defined transmission symbol position within the subframe;
wherein the CFI includes;
first CFI values of M bits among the N bits representing a number of transmission symbols within the LL TTI, andsecond CFI values of L bits among the N bits representing configuration information of a control region and a data region within the LL TTI.

Abstract
Disclosed herein is a base station of a mobile communication system configuring at least one low latency transmission time interval (TTI) within a length of at least one transmission symbol in a subframe including a plurality of transmission symbols and transmitting LL (low latency) TTI related information using a physical control format indicator channel (PCFICH) transmitted at a pre-defined transmission symbol position within the subframe.

4. An apparatus for configuring a transmission time interval in a mobile communication system, comprising:
-
a processor configuring at least one low latency transmission time interval (TTI), with a length of at least one transmission symbol and shorter than a length of one subframe, in a subframe including a plurality of transmission symbols; and a transceiver transmitting LL (low latency) TTI related information using a control format indicator (CFI) of N bits larger than 2 bits of a physical control format indicator channel (PCFICH) transmitted at a defined transmission symbol position within the subframe; wherein the CFI includes; first CFI values of M bits among the N bits representing number of transmission symbols within the LL TTI, and second CFI values of L bits among the N bits representing configuration information of a control region and a data region within the LL TTI the PCFICH at a predefined transmission symbol position within the subframe. - View Dependent Claims (5, 6, 7, 8)
