Abstract
A method is performed by a network node of a communication network. The communication network comprises a plurality of coordinated radio access network nodes for transmitting multiple streams of data to a wireless device in a given time resource. The method comprises: causing transmission, to the wireless device, of an indication that the wireless device should perform multiple separate phase-tracking processes on the signals received from the plurality of coordinated radio access network nodes in the given time resource.
Claims26
A method performed by a network node of a communication network, the communication network comprising a plurality of coordinated radio access network nodes for transmitting multiple streams of data to a wireless device in a given time resource, the method comprising:
- causing transmission, to the wireless device, of an indication that the wireless device should perform multiple separate phase-tracking processes on signals received from the plurality of coordinated radio access network nodes in the given time resource, wherein the indication comprises an indication that the wireless device should perform a respective phase-tracking process on each of multiple streams of data received from the plurality of coordinated radio access network nodes.
A method performed by a wireless device for receiving data from a plurality of coordinated radio access network nodes, the plurality of coordinated radio access network nodes transmitting multiple streams of data to the wireless device in a given time resource, the method comprising:
- receiving, from a network node, an indication that the wireless device should perform multiple separate phase-tracking processes on signals received from the plurality of coordinated radio access network nodes in the given time resource, wherein the indication comprises an indication that the wireless device should perform a respective phase-tracking process on each of multiple streams of data received from the plurality of coordinated radio access network nodes.
A network node for a communication network, the communication network comprising a plurality of coordinated radio access network nodes for transmitting multiple streams of data to a wireless device in a given time resource, the network node comprising processing circuitry and a non-transitory machine-readable medium storing instructions which, when executed by the processing circuitry, cause the network node to:
- cause transmission, to the wireless device, of an indication that the wireless device should perform multiple separate phase-tracking processes on signals received from the plurality of coordinated radio access network nodes in the given time resource, wherein the indication comprises an indication that the wireless device should perform a respective phase-tracking process on each of multiple streams of data received from the plurality of coordinated radio access network nodes.
A wireless device for receiving data from a plurality of coordinated radio access network nodes, the plurality of coordinated radio access network nodes transmitting multiple streams of data to the wireless device in a given time resource, the wireless device comprising processing circuitry and a non-transitory machine-readable medium storing instructions which, when executed by the processing circuitry, cause the wireless device to:
- receive, from a network node, an indication that the wireless device should perform multiple separate phase-tracking processes on signals received from the plurality of coordinated radio access network nodes in the given time resource, wherein the indication comprises an indication that the wireless device should perform a respective phase-tracking process on each of multiple streams of data received from the plurality of coordinated radio access network nodes.
