application date of the original application: 2016 (7 months) and 13 days
- -application number of the original application: 201610547491.0
The invention of the original application is named: method and device in wireless communication
Technical Field
The present application relates to transmission schemes for wireless signals in wireless communication systems, and more particularly, to methods and apparatus in a base station and a UE supporting low latency communication.
Background
In the conventional LTE (Long-Term Evolution) and LTE-a (Long Term Evolution Advanced, enhanced Long Term Evolution) systems, a TTI (Transmission Time Interval), a Subframe (Subframe), or a PRB (Physical Resource Block) (Pair) corresponds to one ms (milli-second, millisecond) in Time. An LTE subframe includes two Time slots (Time slots), which are a first Time Slot and a second Time Slot, respectively, and the first Time Slot and the second Time Slot occupy the first half millisecond and the second half millisecond of the LTE subframe, respectively.
In a conventional LTE system, an initial value of a generated sequence corresponding to a DMRS (Downlink Modulation Reference Signal) changes with a position of a subframe in which the DMRS is located in a radio frame, so as to increase randomness of the DMRS sequence and combat inter-cell interference.
An important application scenario in Reduced Latency (reduction of delay) in 3GPP (3rd Generation Partner Project) Release 14 and New Generation Radio access technologies (NR) is URLLC (Ultra-Reliable and Low Latency Communications). For URLLC scenarios, the conventional LTE frame structure needs to be redesigned. New sTTI (Short TTI, Short transmission time interval) will be introduced by future systems.
Disclosure of Invention
A design method for visually supporting sTTI (transmission time interval) is to keep the generating sequence of the DMRS consistent with a traditional system, namely, the initial value of the generating sequence of the DMRS changes along with the time domain position of a subframe in which the DMRS is positioned in a wireless frame. However, this method may cause a problem that, if DMRSs configured by UEs of two neighboring cells interfere with a given sTTI in a subframe, the interference may exist in all subsequent sttis of the given sTTI in the subframe, and thus performance loss may occur.
The present application provides a solution to the above problems.
