System and Method for Beam-Based Physical Random-Access |
| 摘要 |
A method in a wireless device for performing random access to a network node. The method comprises receiving a set of downlink beam-specific reference signals, BRS, from the network node, and determining a preferred BRS based on the received signal power for each BRS. The method also comprises selecting, based on the preferred BRS, a random-access resource to be used for transmitting a random-access attempt to the network node, as well as using the selected random-access resource when transmitting a random-access attempt to the network node, whereby the selection of random-access resource indicates to the network node which downlink beam is preferred by the wireless device to be used for downlink transmissions. |

1. A method in a wireless device for performing random access to a network node, the method comprising:
receiving a set of downlink beam-specific reference signals, BRS, from the network node; determining a preferred BRS based on the received signal power for each BRS; and selecting, based on the preferred BRS, a random-access resource to be used for transmitting a random-access attempt to the network node; as well as using the selected random-access resource when transmitting a random-access attempt to the network node, whereby the selection of random-access resource indicates to the network node which downlink beam is preferred by the wireless device to be used for downlink transmissions. |
