METHOD OF PROVIDING CONTROL INFORMATION FOR USER EQUIPMENT IN LTE COMMUNICATION SYSTEM
First Claim
Patent Images
1. A method implemented in a base station of providing control information to a user equipment (UE) over a wireless communications system, the method comprising:
- scrambling an enhanced physical down link control channel (E-PDCCH) comprising the control information;
modulating the E-PDCCH;
mapping the E-PDCCH on an allocated physical resource block (PRB);
transmitting the E-PDCCH to the UE;
mapping the E-PDCCH on the allocated PRB on a primary carrier component of the wireless communications system; and
providing full cross carrier scheduling on at least one of physical down link shared channel (PDSCH) and physical uplink shared channel (PUSCH),wherein the UE communicates over the wireless communications system according to the control information, andwherein both localised and distributed transmission is supported for the E-PDCCH.

Abstract
There is provided a method implemented in a base station (11) of providing control information to a UE (13) over a wireless communications system (10). This method includes: scrambling (32) an E-PDCCH including the control information; modulating the E-PDCCH; mapping (34) the E-PDCCH on an allocated PRB; and transmitting (12) the E-PDCCH to the UE (13). The UE (13) communicates over the wireless communications system (10) according to the control information.

17. A method implemented in a user equipment (UE) of receiving control information from a base station over a wireless communications system, the method comprising:
-
receiving an enhanced physical down link control channel (E-PDCCH) from the base station; and communicating over the wireless communications system according to the control information, wherein the E-PDCCH comprises the control information, wherein the E-PDCCH is scrambled and modulated by the base station and mapped on an allocated physical resource block (PRB) by the base station on a primary carrier component of the wireless communications system, wherein full cross carrier scheduling is provided by the base station on at least one of physical down link shared channel (PDSCH) and physical uplink shared channel (PUSCH), and wherein both localised and distributed transmission is supported for the E-PDCCH.
