Spatial multiplexing of different radio technologies

A method of wireless communication, comprising:

• configuring reception resources into one or more spatial layers organized into subframes, wherein reception resources in each subframe are along a two-dimensional grid of time and frequency resource elements comprising symbols and subcarriers,
• for each spatial layer, configuring the corresponding resource elements by:
• designating a first group of resource elements as common resources that carry signal transmissions from a first group of user devices according to a first radio technology;
• designating a second group of resource elements as common resources that carry signal transmissions from a second group of user devices according to a second radio technology;
• designating a third group of resource elements as device-specific resources that carry device-specific signal transmissions from user devices in the first group of user devices;
• designating a fourth group of resource elements as device-specific resources that carry device-specific signal transmissions from user devices in the second group of users;
• and
• providing simultaneous uplink connectivity to the first group of user devices and the second group of user devices based on use of reception resources from the one or more spatial layers, such that the reception resources from the one or more spatial layers are orthogonal in a space dimension.

A method of wireless communication, comprising:

• operating a base station using multiple spatial beams to provide simultaneous wireless services to user devices implementing multiple radio technologies,
• wherein communication resources between the base station and the user devices are arranged as repetitive subframes of resource elements, wherein each resource element comprises a unit of time resource and a unit of frequency resource,
• wherein a first portion of each subframe is designated for carrying device-specific signals, and
• wherein resource elements in the first portion of each subframe designated for carrying device-specific signals are configured to use spatial multiplexing over the multiple spatial beams to provide wireless service to user devices implementing multiple radio technologies;
• wherein resources elements are allocated to a specific user device for both downlink and uplink signals are based on processing of uplink reference signal transmissions from the specific user device.
