Method for controlling timing in a communications channel
View Patent ↗A method for controlling the flow of information on a high-speed channel between a UE and a Node B is provided. Timing of the high-speed channel is based on timing associated with a low-speed channel and a time at which a grant signal is received from the Node B. Upon receiving a grant signal, the UE adds a preselected duration of time to the timing of the low-speed channel to provide timing on the high-speed channel, where the preselected duration of time is selected to maintain substantial orthogonality between the high-speed and low-speed channels.
1. A method, comprising:
determining timing associated with a first channel;
receiving a grant signal permitting transmission of information over a second channel; and
transmitting information over the second channel at a time related to the timing of the first channel and a time at which the grant signal is received, wherein transmitting information over the second channel further comprises transmitting information over the second channel a preselected duration of time after the timing associated with the first channel, and wherein transmitting information over the second channel a preselected duration of time after the timing associated with the first channel further comprises determining the preselected duration of time by multiplying a variable (m) times a constant, wherein the constant is related to the timing of the first channel, and wherein determining the preselected duration of time further comprises multiplying a variable (m) times a constant, wherein the constant is about 10% of a period of time associated with the timing of the first channel.
2. A method, comprising:
determining timing associated with a first channel;
receiving a grant signal permitting transmission of information over a second channel; and
transmitting information over the second channel at a time near a preselected target time while maintaining substantial orthogonality with the timing of the first channel, wherein transmitting information over the second channel further comprises transmitting information over the second channel a preselected duration of time after the timing associated with the first channel, wherein transmitting information over the second channel a preselected duration of time after the timing associated with the first channel further comprises determining the preselected duration of time by multiplying a variable (m) times a constant, wherein the constant is related to the timing of the first channel, wherein determining the preselected duration of time further comprises multiplying a variable (m) times a constant, wherein the constant is a portion of time associated with the timing of the first channel, and wherein determining the preselected duration of time further comprises multiplying a variable (m) times a constant, wherein the constant is about 10% of a period of time associated with the timing of the first uplink channel.
