摘要： Aspects of this disclosure relate to a pair of wireless communication devices wirelessly communicating with a network system in a coordinated manner. The wireless communication devices of the pair can be in communication with each other via a wireless peer-to-peer link. A primary wireless communication device can communicate a first part of a multiple-input multiple-output (MIMO) transmission via cellular communications and a second part of the MIMO transmission via the peer-to-peer link. This can enable the primary wireless communication device to communicate with the network system at a higher data rate and/or at a higher MIMO rank.

摘要： Aspects of this disclosure relate to user equipment assisted multiple-input multiple-output (MIMO) downlink configuration. Features are described for a user equipment determination of a desired transmission mode and/or active set of serving nodes for wireless communication service(s). The user equipment may submit a request for the desired mode and/or nodes to a network controller such as a baseband unit. The user equipment may subsequently receive a configuration for the requested wireless communication service(s).

摘要： Aspects of this disclosure relate to a time-division duplex (TDD) multiple-input multiple-output (MIMO) system that includes a plurality of nodes. The plurality of nodes collectively includes antennas divided into groups. Reference signals can be transmitted from each group of antennas to one or more other groups of antennas during respective time slots. Channel estimates can be generated based on the received reference signals. The channel estimates can be jointly processed to generate calibration coefficients. Each calibration coefficient can represent a ratio associated with a transmit coefficient and a receive coefficient. Example algorithms for the joint processing are disclosed.

摘要： 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.

摘要： Aspects of the disclosure relate to an active set management scheme implemented by a scheduler in a multiple-input multiple-output (MIMO) network that minimizes capacity and interference issues. For example, the scheduler can initially group each base station into a separate active set. The scheduler can then analyze each active set to determine whether the active set is a good or bad based on the level of interference in and the number of MIMO transmit dimensions available in the respective active set. If the scheduler determines that an active set is a bad, the scheduler can determine a set of metrics that each represent a capacity and link quality that would result if the bad active set is combined with another active set. Based on the set of metrics, the scheduler can combine the bad active set with another active set, and repeat this process until no bad active sets remain.

摘要： Aspects of this disclosure relate to systems and methods for wirelessly communicating data. A network system can wirelessly communicate with a user equipment in traffic mode and in a virtual transmit-receive point mode. In the virtual transmit-receive point mode, the user equipment functions as a virtual transmit-receive point of a network system for serving another user equipment. The network system can signal a particular user equipment to operate in the virtual transmit-receive point mode. The network system can wirelessly communicate cellular data for another user equipment with the particular user equipment in the virtual transmit-receive point mode.

摘要： Aspects of this disclosure relate to of managing wireless communication between a cellular carrier network and a wireless communication device. A request that a wireless communication device connect to the cellular carrier network via a cellular link between an anchor device and the cellular carrier network can be detected. Wireless communication of information associated with the wireless communication device between the anchor device and the cellular carrier network can be tracked. An account associated with the anchor device can be updated based on serving as an anchor device for the wireless communication device.
