Abstract: There is provided a method at a network node of a communication network, comprising: receiving an uplink reference signal from a user equipment; estimating, based on the received uplink reference signal, delay information regarding a delay profile of a communication channel between the user equipment and the network node and spatial information regarding the communication channel; applying both the delay information and the spatial information in precoding of at least one downlink reference signal; transmitting the at least one precoded downlink reference signal to the user equipment; and receiving, from the user equipment as a response to the transmission of the at least one precoded downlink reference signal, channel information, the channel information indicating at least non-zero coefficients of at least one channel transmission layer.

Abstract: Improved techniques of include performing random access in an antenna-distributed network include introducing a new parameter, as reduced Tx power indicator, in the RAR of Msg-2 that indicates a reduced total Tx power of all antenna nodes of the antenna-distributed network. When the gNB receives a Msg-1, the gNB determines a subset of the distributed antenna nodes to which the gNB will send the RAR in the Msg-2 with the reduced total Tx power needed to transmit the Msg-2 to only those antenna nodes in the subset. The RAR includes a new parameter indicating the reduced total Tx power used to transmit the RAR to the UE. The UE then uses the value of the new parameter to estimate a pathloss for the Msg-3 and PUSCH transmission.
