Radio resources for data and scheduling information

摘要

A base station transmits on a first control channel first scheduling information for a control message. First radio resources of the first control channel start from the first symbol of each subframe in a plurality of subframes. The base station transmits the control message configuring second radio resources of a second control channel. The second radio resources comprise resource blocks in a subset of subframes in the plurality of subframes. The control message indicates the subset of subframes and a starting symbol of the second control channel. The base station transmits second scheduling information on the second control channel.

1. A method for use in a base station, the method comprising:
a) transmitting on a Physical Downlink Control Channel (PDCCH), to a wireless device, first scheduling information for a radio resource control (RRC) message, first radio resources of said PDCCH in a subframe in a plurality of subframes starting from the first OFDM symbol of said subframe; b) transmitting, to said wireless device, said RRC message comprising configuration parameters of second radio resources of an enhanced PDCCH (ePDCCH), said second radio resources comprising one or more resource blocks in a subset of subframes in said plurality of subframes, said RRC message indicating:
i) said subset of subframes;ii) a first starting OFDM symbol of both said ePDCCH and a data channel in said subset of subframes; and iii) frequency resources for said ePDCCH in terms of resource blocks in said subset of subframes; and
c) transmitting, to said wireless device, second scheduling information on said ePDCCH for a packet transmitted on said data channel.
