Abstract: An apparatus, at a network entity, for scheduling multi-user multiple-input multiple-output (MU-MIMO) transmissions to a co-scheduled set of user equipment (UEs) from an antenna array comprising multiple panels is disclosed. The apparatus comprises: a processor; a memory communicatively coupled to the processor; and executable instructions code stored in the memory, which when executed by the processor, cause the processor to: determine a reduced set of entries of panel-to-UE assignment from among multiple combinations of panel-to-UE assignment; and select, from within the reduced set, an entry of the panel-to-UE assignment for scheduling, based on a proportionately fair (PF) metric, wherein a panel-to-UE assignment is a mapping of the panels assigned to transmit to a selection of the UEs using associated serving beams configured for transmission to the respective UEs.

Abstract: Wireless communications systems and methods related to allocating resource blocks and resource block groups in a system band in order to reduce overhead associated with resource allocation. To reduce overhead, the wireless communication device communicates a signal in a control channel that indicates a general area and a resource block in the general area that stores data. The wireless communication device then communicates multiple resource blocks that include the resource block and communicates the data in the resource block using the signal. To reduce overhead, the wireless communication device also communicates multiple mappings for each resource block group into a set of resource blocks and a signal in a control channel that selects one of the multiple mappings. The communication device then determines resource blocks that are included in the resource block group according to the mapping, and communicates data in these resource blocks.

Abstract: Methods, systems, and devices for wireless communication are disclosed. Flexible interleaving configurations may be employed to support various operations, including beamforming. Flexible interleaving may include dynamically or semi-statically determining a combination of bit-level, tone-level, tone-group level, or other interleaving technique for one or more transmissions. The interleaving configuration may be based on delay spread, a coherence bandwidth, a signal to noise ratio, a Doppler spread, or a combination thereof. An interleaving configuration may be a determination may be made by a base station or some other network entity and explicitly signaled to another device. Additionally or alternatively, the determination may be made based on one or more implicit rules, which may be based on a variety of factors (e.g., available bandwidth, modulation and coding scheme (MCS), code block (CB) size). Further, interleaving may be enabled (or disabled) under certain conditions.

Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Abstract: A UE may be configured to communicate using one of analog beamforming or hybrid beamforming. The UE may receive a set of beamformed signals from a base station. The UE may determine a set of angular spread values associated with a set of clusters in a channel between the base station and the UE based on the set of beamformed signals received from the base station. The UE may transmit the set of angular spread values to the base station. The UE may receive, from the base station based on the set of angular spread values, a set of transmission ranks associated with at least one cluster of the set of clusters. The UE may communicate at least one data stream with the base station across the at least one cluster using the set of transmission ranks associated with the at least one cluster of the set of clusters.
