Abstract
In a telecommunication system, a method of controlling and implementing uplink transmission schemes specifically for user equipment having multiple input/multiple output (MIMO) capability, including initializing said scheme at a network element; forwarding a message from said network element to said terminal indicating said scheme; transmitting uplink signals according to said scheme. It may include selecting a pre-coding arrangement such as a Transmitted Precoding Matrix Indicator or other scheduling grant information.
Claims48
A method comprising:
- receiving, by a first network element, a first scheduling grant that contains a precoding scheme used for transmitting a first signal from the first network element to a second network element;
- transmitting the first signal to the second network element according to the precoding scheme;
- subsequent to the transmission of the first signal, receiving, by the first network element, a second scheduling grant used for transmitting a second signal from the first network element to the second network element, wherein the second scheduling grant does not contain a precoding scheme used for transmitting the second signal;
- and
- transmitting the second signal to the second network element according to the first scheduling grant or the precoding scheme.
2 more elements
A network element comprising:
- one or more processors;
- and
- one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the system to perform the following:
- receiving, by the network element, a first scheduling grant that contains a precoding scheme used for transmitting a first signal from the network element to another network element;
- transmitting the first signal to said another network element according to the precoding scheme;
- subsequent to the transmission of the first signal, receiving, by the network element, a second scheduling grant used for transmitting a second signal from the network element to said another network element, wherein the second scheduling grant does not contain a precoding scheme used for transmitting the second signal;
- and
- transmitting the second signal to said another network element according to the first scheduling grant or the precoding scheme.
5 more elements
A method comprising:
- forwarding a first scheduling grant that contains a precoding scheme used for transmitting a first signal from a first network element to a second network element;
- receiving the first signal from the first network element according to the precoding scheme;
- subsequent to the reception of the first signal, forwarding a second scheduling grant used for transmitting a second signal from the first network element to the second network element, wherein the second scheduling grant does not contain a precoding scheme used for transmitting the second signal;
- and
- receiving the second signal from the first network element according to the first scheduling grant or the precoding scheme.
2 more elements
A network element comprising:
- one or more processors;
- and
- one or more memories including computer program code, the one or more memories and the computer program code configured, with the one or more processors, to cause the network element to perform the following:
- forwarding a first scheduling grant that contains a precoding scheme used for transmitting a first signal from another network element to the network element:
- receiving the first signal from said another network element according to the precoding scheme;
- subsequent to the reception of the first signal, forwarding a second scheduling grant used for transmitting a second signal from said another network element to the network element, wherein the second scheduling grant does not contain a precoding scheme used for transmitting the second signal;
- and
- receiving the second signal from said another network element according to the first scheduling grant or the precoding scheme.
