Channel configuration in a wireless network
First Claim
1. A base station comprising:
- one or more processors; and
memory storing instructions that, when executed, cause the base station to;
transmit, to a wireless device, a first control message comprising configuration parameters for a control channel, wherein the control channel is associated with one or more sets of resource blocks in one or more subframes of a plurality of subframes, and wherein the configuration parameters indicate;
the one or more subframes in which the one or more sets of resource blocks associated with the control channel are configured; and
a starting symbol, corresponding to both the control channel and a downlink data channel, for each subframe of the one or more subframes in which the one or more sets of resource blocks associated with the control channel are configured;
transmit, via the control channel, first scheduling information for a first packet;
receive the first packet; and
transmit, via a feedback channel, a positive or negative acknowledgement in a first subframe of the plurality of subframes, wherein the feedback channel begins at a symbol occurring first in each subframe of the plurality of subframes.

Abstract
According to some aspects, a base station may transmit a control message to a wireless device. The control message may comprise configuration parameters for a control channel associated with sets of resource blocks in one or more subframes of a plurality of subframes. The configuration parameters may indicate the one or more subframes in which the resource blocks of the control channel are configured. The configuration parameters may further indicate a starting symbol, such as an offset number of symbols, for the control channel and an associated downlink data channel within the one or more subframes. The base station may transmit, via the control channel, scheduling information for a packet. The base station may receive the packet and transmit an acknowledgement via a feedback channel beginning at the first symbol of a subframe in the plurality of subframes.
