Method of control signaling transmission and reception for user equipment in a LTE communication system

摘要

A method implemented in a base station used in a wireless communications system is disclosed. The method includes transmitting, to a user equipment (UE), an indication of a type of enhanced physical downlink control channel (ePDCCH) transmission, where the type of ePDCCH transmission comprises either localized transmission or distributed transmission, and transmitting, to the UE, an indication of the number of physical resource block (PRB) pairs allocated for the ePDCCH transmission, where the indication of the number of PRB pairs allocated for the ePDCCH transmission is conveyed in 2 or 3 bits. Other methods, apparatuses, and systems also are disclosed.

1. A method implemented in a base station used in a wireless communications system, the method comprising:
transmitting, to a user equipment (UE), an indication of a type of enhanced physical downlink control channel (ePDCCH) transmission, where the type of ePDCCH transmission comprises either localized transmission or distributed transmission; and transmitting, to the UE, an indication of the number of physical resource block (PRB) pairs allocated for the ePDCCH transmission, where the indication of the number of the PRB pairs allocated for the ePDCCH transmission is conveyed in 2 or 3 bits, wherein:
the indication of the type of ePDCCH transmission is conveyed in 1 bit,the indication of the type of ePDCCH transmission and the indication of the number of PRB pairs allocated for the ePDCCH transmission are transmitted via radio resource control (RRC) signaling,the indication of the type of ePDCCH transmission and the indication of the number of the PRB pairs allocated for the ePDCCH transmission are dynamically indicated from subframe to subframe, andif there is one or more remaining PRB pairs which are not allocated for the ePDCCH transmission, at least one of the remaining PRB pairs are used as physical downlink shared channel (PDSCH) transmission.
