Embodiment Construction

[0036] figure 1 A 3GPP LTE system is shown. A 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system 10 includes at least one eNodeB (eNB) 11. A respective eNB 11 provides communication services to specific geographical areas 15a, 15b and 15c (commonly referred to as cells). Each cell can be divided into a number of areas (referred to as sectors). User Equipment (UE) 12 may be fixed or mobile and may be implemented in a mobile station (MS), mobile terminal (MT), user terminal (UT), subscriber station (SS), wireless device, personal digital assistant (PDA) , wireless modem, handheld device and other names. An eNB 11 generally refers to a fixed station that communicates with a UE 12, and may be referred to by other names such as base station (BS), base transceiver system (BTS), access point (AP), and the like.

[0037] Generally, a UE belongs to one cell, and the cell to which the UE belongs is called a serving cell. An eNB that provides a communication ...

Abstract

A method and apparatus for determining a set of control resources for system information in a wireless communication system are provided. A user equipment (UE) receives a configuration of a control resource set (CORESET) for residual system information (RMSI) from a network via a synchronization signal (SS) block, and determines said control for said RMSI from said configuration resource set. The SS block may include a physical broadcast channel (PBCH). A time and frequency location of a common search space (CSS) for the RMSI may be aligned with the SS block by at least one of time division multiplexing (TDM) or frequency division multiplexing (FDM).

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a method and apparatus for configuring a control channel for New Radio Access Technology (NR) in a wireless communication system. Background technique [0002] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a technology that enables high-speed packet communication. Many schemes have been proposed for the LTE goals, including those aimed at reducing user and provider costs, improving service quality, and extending and improving coverage and system capabilities. 3GPP LTE requires a reduction in cost per bit, an increase in service availability, flexible use of a frequency band, a simple structure, an open interface, and sufficient power consumption of a terminal as required by an upper level. [0003] As more communication devices require more communication capacity, there is a need for improved mobile broadband communication over existing radi...
