Abstract: Aspects of the disclosure relate to a selection scheme implemented by a scheduler in a multiple-input multiple-output (MIMO) network to identify which users to schedule simultaneously during the same time slot. For uplink communications and a particular frequency wholeband or sub-band, the scheduler can obtain uplink channel information for channels between base stations and UEs. The scheduler can then determine a strength of the channels using the uplink channel information, order the UEs using a fairness metric based on the channel strengths, and compute one or more QR decompositions to identify whether a spatial dimension of a UE is roughly or approximately orthogonal to spatial dimension(s) of other UEs selected to be served during a time slot being scheduled. If the spatial dimensions are roughly or approximately orthogonal, the scheduler selects the UE to be served at the same time as other UEs already selected.

Abstract: An opportunistic asynchronous operation for coordinated new radio (NR) shared spectrum (NR-SS) operations is discussed. In a wireless network having at least one contention-based shared channel in which communications are configured having one or more control intervals time division multiplexed with one or more data intervals for transmission opportunities, a base station receives data for communication at a time during a current data interval on a contention-based shared channel. The base station will review its received signals on the contention-based shared channel during the previous control interval located immediately prior to the current data interval. If none of the received signals indicate a contention-resolution of the contention-based shared channel, the base station may begin an attempted transmission by performing an abbreviated clear channel assessment (CCA). If the CCA is detected as clear, the data may be transmitted.

Abstract: Aspects of the disclosure relate to a selection scheme implemented by a scheduler in a multiple-input multiple-output (MIMO) network to identify which users to schedule simultaneously during the same time slot. For downlink communications and a particular frequency wholeband or sub-band, the scheduler can determine downlink channel information using uplink channel information for channels between base stations and UEs. The scheduler can then determine a strength of the channels using the downlink channel information, order the UEs using a fairness metric based on the channel strengths, and compute one or more QR decompositions to identify whether a spatial dimension of a UE is roughly or approximately orthogonal to spatial dimension(s) of other UEs selected to be served during a time slot being scheduled. If the spatial dimensions are roughly or approximately orthogonal, the scheduler selects the UE to be served at the same time as other UEs already selected.

Abstract: Aspects of this disclosure relate to an improved coordinated multipoint (CoMP) network operating in a millimeter wave frequency band in which user equipment (UEs) combine signals received across multiple spatial beams from multiple base stations. The improved CoMP network can achieve high throughput, low latency, and/or high reliability at millimeter wave frequencies while maintaining a reasonable network complexity (e.g., lower network overhead than CoMP networks implemented with coherent combining). For example, the improved CoMP network can include one or more base stations and one or more UEs. Multiple base stations can transmit the same data across multiple spatial beams to a UE at the same time. The base stations may use information provided by a UE to identify an active set of base stations and/or spatial beams to serve the UE.
