According to an example embodiment, an example method may include determining, by a network node in a wireless network, whether a size of a data packet is greater than a threshold size; transmitting, by the network node, the data packet via a frequency interlace if the size of the data packet is less than or equal to the threshold size; transmitting, by the network node, the data packet via contiguous wideband frequency resources if the size of the data packet is greater than the threshold size.

Data transmission via frequency interlace for wireless networks

A distributed unit, DU, of a radio access node configured to operate in a scenario where the DU is one of multiple DUs serving links to a multi-connected entity, acquires a first DU radio resource configuration for the DU, acquires a first link radio resource configuration corresponding to a first link of a multi-connectivity link of a multi-connected entity, wherein the first link is served by the DU, acquires a multiplexing configuration of the multi-connectivity link, and determines availability of at least one radio resource for the multi-connectivity link based on the first DU radio resource configuration, the first link radio resource configuration, and the multiplexing configuration.

A method may include determining, by a user equipment, a beam alignment reference value and a beam alignment test value; and determining, by the user equipment, based on the beam alignment reference value and the beam alignment test value, that a user equipment receive beam used by the user equipment is not aligned with a transmit beam of the base station.

Beam alignment verification for wireless networks

Systems, methods, apparatuses, and computer program products for GIS-NR beamforming for mmWave. For example, certain embodiments may provide for beam realignment, through which a serving network node may be able to re-position its beam towards a UE without the UE explicitly measuring and signalling to the network node the need for realignment. Instead of performing the traditional UE-based exhaustive beam search, the serving network node may proactively switch the beam in an attempt to track the UE movements. The serving network node may do this by corroborating information from two types of sources: 1) a set of neighbor mobile or fixed network nodes and 2) a geographic information system (GIS).

Delta beam comparison for UL/DL beam misalignment detection

To establish a multi-AP RRC connection with a user device UD the UD in the coverage area of multiple APs selects suitable ones as cluster set candidates and reports this list to a temporary serving AP the UD chooses. The multi-AP connection itself is setup by the cluster set manager CSM. The CSM collects information from each AP about control channels and load in order to choose which APs will be in the cluster, which will be the serving AP, and to setup the multi-AP connection with the UD. Multiple message exchanges are described for this purpose. Once the multi-AP connection is established, if the UD's connection with the serving AP fails the UD can handover to another AP of the cluster set without having to re-establish a new RRC connection. This is particularly useful for networks subject to severe shadowing effects such as mmWave 5G.

Further, the exemplary embodiments of the invention provide at least a method and an apparatus to determine a dominant access point of a cluster of access points based on signaling from at least one access point associated with the cluster of access points; and in response to the determining, direct communications towards the dominant access point of the cluster of access points.

Beam management for interference mitigation for wireless networks

A group of data symbols for a current block of data symbols in multiple blocks received over a communication channel is equalized, based on a pilot block, to generate a group of equalized symbols. The group of equalized symbols is de-rotated as a function of a current phase estimate to determine initial de-rotated equalized symbols. The phase estimate is an estimate of phase caused by noise for blocks previous to the current block. Additionally, a phase metric is calculated from real and imaginary parts of the initial de-rotated equalized symbols, wherein the phase metric estimates phase caused by noise for the current block. The current phase estimate is updated with the phase metric. The initial de-rotated equalized symbols are de-rotated by the phase metric to determine final equalized and de-rotated symbol estimates. The final equalized and de-rotated symbol estimates are output. Apparatus, methods, and computer program products are disclosed.
