Abstract: Orthogonal DMRS ports with resource block reuse in a single cell is provided. ABS comprises: a BBE and RUs. The BS transmits user data to each of a plurality of UEs on a PDSCH using a PRB allocation for the cell. The PRB and cell are the same for all UEs. The PRB comprises DMRS symbols. The BS transmits user data to each UE on the PDSCH using a respective non-intersecting subset of the RUs. No RU transmits user data on the PDSCH using the PRB to more than one UE. The BBE: determines non-intersecting sets of DMRS ports; assigns one set to each UE; and causes the BS to transmit UE-specific DMRS to UE on the DMRS ports in the set assigned to that UE using only a respective non-intersecting subset of RUs used for transmitting user data to that UE on the PDSCH using the PRB.

Abstract: A small cell for automatic configuration of an operational parameter includes at least one processor configured to determine a provisioned list of operational parameters. The at least one processor is also configured to sort the provisioned list into a sorted list. The at least one processor is also configured to select the operational parameter from the sorted list based on a BC ID for the small cell, a sector ID for a sector implemented by the small cell, or some combination.

Abstract: One embodiment is directed wirelessly communicating with user equipment (UE) operating using discontinuous reception (DRX). When a rank for the UE has changed is determined and, in response when that happens, if an ON duration for a current DRX cycle for the UE will elapse during a current subframe is determined. In response to making such determination about the ON duration, a dummy assignment of resource blocks on a downlink shared channel is sent to the UE. The UE extends the ON duration of the current DRX cycle in response to the dummy assignment. If a channel quality indication (CQI) report has been made by the UE is determined and, in response thereto, a modulation and coding scheme (MCS) used for communicating with the UE is updated based on the reported rank and reported CQI. The dummy assignment is not made for communicating actual data to the UE.

Abstract: Systems and methods for flexible antenna configurations and beamforming are provided. In one example, a system includes: at least one controller configured to implement at least some functions for one or more layers of a wireless interface used to communicate with UEs; remote unit(s) communicatively coupled to the at least one controller; and antenna elements communicatively coupled to the remote unit(s), each respective antenna element oriented in a respective direction different than other antenna elements. The at least one controller is configured to: determine a location of a UE in a cell of the system and/or channels between the antenna elements and the UE; select antenna element(s) for use in transmitting downlink signals to the UE based on the location of the UE and/or the channels between the antenna elements and the UE; and transmit downlink signals to the UE via the selected antenna element(s) in a first time period.

Abstract: Systems and methods for RACH occasion blocking for 5G NR TDD systems implementations are provided herein. In one example, a method for RACH occasion blocking by a base station includes configuring one or more first Synchronization Signal Blocks SSBs and one or more second SSBs for a cell. The method further includes mapping the one or more first SSBs to one or more first RACH occasions and the one or more second SSBs to one or more second RACH occasions. The method further includes transmitting only the one or more first SSBs and not the one or more second SSBs.
