The present disclosure discloses a method and an apparatus for adjusting a working status of an aggregated link. The method includes: when determining to switch a modulation mode of a first sub-link of an aggregated link from a first modulation mode to a second modulation mode, determining a transmission delay of transmitting a data slice in the second modulation mode by using the first sub-link; comparing the transmission delay of transmitting a data slice in the second modulation mode by using the first sub-link with a transmission delay of transmitting a data slice by using another sub-link of the aggregated link, to obtain a difference; and if the difference meets a preset condition, sending information for controlling a working status of the first sub-link to a transmit end device, so that the transmit end device controls the working status of the first sub-link in the second modulation mode.

A base station transmits a layered data signal to multiple devices that are in close proximity to each other where the layered data signal includes at least first data on a first data layer directed to a first device and second data on a second data layer directed to a second device. The base station also transmits a single control message to both devices where the control message comprises location dependent control information directed to both devices. The control message also comprises data layer control information arranged in multiple fields where data layer control information in a field is associated with a device and allows the associated device to recover the data from a data layer assigned to the device.

The described technology is generally directed towards ultra-reliable low latency communications between a network device and a user equipment, using scheduling parameters for a less conservative block error rate threshold based on the spectral efficiency. A network device obtains channel state information comprising a rank indicator, a layer indicator indicating a strongest layer, a first channel quality indicator corresponding to a first coding rate and a first modulation value for a first conservative block error rate threshold value, and a second channel quality indicator corresponding to a second coding rate and second modulation value for a second conservative block error rate threshold value. When the network device determines that that the first coding rate and the first modulation value are suitable for ultra-reliable low latency communications, the network device schedules the user equipment to use the first coding rate and the first modulation value, e.g., using the strongest layer.

A communication device is described comprising a receiver configured to receive data comprising information representing a required quality of service of the transmission of the data, hardware resources configured to perform a processing of the data and a controller configured to set a speed of the processing of the data by the hardware resources based on the determined required quality of service.

A data packet for delivery to a user equipment can be inspected. Based on the inspecting, whether to use a robust downlink delivery can be determined. Based on the determining, a robust modulation coding scheme (MCS) for the data packet can be selected. The data packet can be transmitted utilizing the selected robust MCS. At least one of the inspecting, the determining, the selecting, and the transmitting is performed using at least one processor of at least one computing system. Related apparatus, systems, techniques, and articles are also described.
