Abstract: A technique includes measuring a received power for each resource of one or more resource pairs, wherein each of the one or more resource pairs includes a resource of a first resource type and a set of resources of a second resource type, wherein the resource of the first resource type is spatially quasi-colocated with the set of resources of the second resource type; selecting, based on a strongest received power, one of the one or more resource pairs for providing a joint quasi-colocation multiple-resource beam report; creating, by the user device, a joint quasi-colocation multiple-resource beam report, wherein the joint quasi-colocation multiple-resource beam report indicates a resource and a corresponding measured received power for each resource of the selected resource pair, including for a resource of the first resource type and each resource of the set of resources of the second resource type of the selected resource pair.

Abstract: Various communication systems may benefit from improved transmissions. For example, a network transmission may benefit from improved throughput and efficiency in non-schedule multiple access communications. A method includes selecting at a user equipment operating in a non-scheduled access scheme at least one of a first codeword or a second codeword based on an amount of data. The data in the non-scheduled access scheme can be spread according to a spreading sequence. The method also includes determining a transport block size for at least one of the first codeword or the second codeword. In addition, the method includes transmitting the data from the user equipment to a network node using at least one of the first codeword or the second codeword.

Abstract: Systems, apparatuses, and methods of beam reporting for rank enhancement are provided. One method may include defining an enhanced beam reporting criteria for user equipment (UE) beam reporting. The enhanced beam reporting criteria may be used for transmission rank enhancement. The method may also include configuring at least one user 5 equipment (UE) with the enhanced beam reporting criteria, and receiving at least one beam report, from the at least one user equipment (UE), according to the enhanced beam reporting criteria configured to the at least one user equipment (UE).

Abstract: Systems, methods, apparatuses, and computer program products for supporting a narrow serving beam in a hierarchical beam configuration. For example, certain embodiments may provide a UE that may receive, from a network node, information of a quasi co-location (QCL) configuration of self-contained, aperiodic, and/or semi-persistent tracking reference signals (TRSs) for sub-beams, where a source for one or more TRSs may be channel state information (CSI-RS) without repetition. In addition, the UE may determine these TRSs as self-contained, for which there are no associated periodic TRSs, if there is a TRS configured for an SSB sub-beam.

Abstract: A method may include transmitting, by a network node within a wireless network to a reference node, a first precoded tracking signal based on estimated precoding weights that are estimated to provide a predetermined signal at the reference node; receiving, by the network node from the reference node, a message including information related to whether or not the predetermined signal was received at the reference node based, at least in part, on the first precoded tracking signal transmitted by the network node; performing the following, by the network node, if the predetermined signal was not received at the reference node: adjusting one or more transmission parameters of the network node, that is estimated to more accurately provide the predetermined signal at the reference node; and transmitting, by the network node, a second precoded tracking signal based on adjusted transmission parameters.

Abstract: Systems, methods, apparatuses, and computer program products for selecting or prioritizing between a physical downlink shared channel (PDSCH) and synchronization signal block (SSB) reception are provided. One method may include, when outside a SMTC window and when PDSCH resource allocation overlaps with an occupied SSB location, selecting between the PDSCH and SSB reception according to defined rules.

Abstract: Systems, methods, apparatuses, and computer program products for non-linear precoding are provided. One method may include combining, by a network node, of linear and non-linear precoding, for example based on specific channel state information acquisition from at least one user equipment, and generating two types of demodulation reference signals for the concatenated linear and non-linear precoding. The method may include multiplexing, by the network node, the two types of demodulation reference signals with data. A first of the two types of demodulation reference signals may be linearly precoded with one linear precoding matrix from a first-stage linear precoder, and another one of the two types may be linearly precoded with both the first-stage linear precoder and a feedforward filter in a second-stage non-linear precoder from the concatenation of linear and nonlinear precoders.
