METHODS AND APPARATUS FOR UPLINK RESOURCE ASSIGNMENT |
| 摘要 |
The present invention relates to a method for uplink transmission performed in a wireless terminal served by a radio network node of a wireless communication system and corresponding radio network node method. The method comprises receiving an assignment for an uplink transmission from the radio network node. The method also comprises determining alternative usages of the assignment based on the received assignment. Each alternative usage is associated with a different DMRS. The method further comprises selecting a usage among the alternative usages of the assignment, and applying the selected usage when transmitting uplink data to the radio network node. The method also comprises transmitting the DMRS associated with the selected usage. |

1. A method for uplink transmission performed in a wireless terminal served by a radio network node of a wireless communication system, the method comprising:
receiving an assignment for an uplink transmission from the radio network node, determining alternative usages of the assignment based on the received assignment, each alternative usage being associated with a different demodulation reference signal, selecting a usage among the alternative usages of the assignment, applying the selected usage when transmitting uplink data to the radio network node, and transmitting the demodulation reference signal associated with the selected usage. |
