A method, network node and wireless device (WD) for dual codebook configuration and channel state information (CSI) combining for large scale active antenna systems (AAS) are disclosed. According to one aspect, a method in a network node includes triggering the WD to transmit in succession or simultaneously, a horizontal CSI report reporting a horizontal CSI set for a horizontal direction of the array and a vertical CSI report reporting a vertical CSI set for a vertical direction of the array, the horizontal CSI set being mapped to a row of the array and the vertical CSI set being mapped to a column of the array. The method also includes receiving the horizontal and vertical CSI reports from the WD, and combining the horizontal and vertical CSI sets into a combined CSI set for at least one of scheduling and beamforming.

Dual codebook configuration and CSI combining for large scale active antenna systems

A method, network node, wireless device and system are provided. According to one aspect of the disclosure, a network node is provided. The network node includes processing circuitry configured to: cause transmission of a Discontinuous Reception, DRX, configuration to a wireless device using communication layer 3 signaling, cause transmission of an indication to the wireless device to trigger activation at one of communication layer 1 and communication layer 2 of the DRX configuration, and optionally determine whether the wireless device has activated the DRX configuration.

Discontinuous reception activation/deactivation based on communication layer 1 and layer 2 signaling

Embodiments described herein provided methods and apparatuses for determining Channel State Information Interference Measurement resources, CSI-IM resources, for interference measurement, wherein a New Radio, NR, base station is spectrum sharing with a Long Term Evolution, LTE, base station. A method in an NR base station includes determining a CSI-IM pattern for a CSI-IM resource, wherein the CSI-IM pattern is defined by one or more first OFDM symbols and a first frequency shift; and transmitting a Channel State Information Reference Signal, CSI-RS, according to a CSI-RS pattern, wherein the CSI-RS pattern is defined by a second OFDM symbol and a second frequency shift, wherein the first frequency shift and the second frequency shift do not overlap and wherein the one or more first OFDM symbols overlap with the second OFDM symbol.

Methods and apparatuses for determining channel state information interference measurement resources

A method implemented by a network device in a communication network is provided. The network device is operable to communicate with a User Equipment UE and a Narrow Band Internet Of Things NB-IoT terminal device in the communication network. Said method may comprise configuring NB-IoT Physical Resource Blocks PRBs. Said method may further comprise when scheduling said UE, if said configured NB-IoT PRBs have not been allocated to said NB-IoT terminal device and if available PRBs other than said configured NB-IOT PRBs are not enough for said UE, attempting to allocate said configured NB-IoT PRBs for said UE. A network device performing said method is also provided. Further, a communication network comprising said network device is also provided.
