Apparatuses, systems, and methods for performing downlink signal reception with antenna panel switching in a wireless communication system. A cellular base station may receive an indication of an antenna panel activation delay from a wireless device. The cellular base station may select a scheduling offset for a transmission to the wireless device based at least in part on the antenna panel activation delay. The scheduling offset may be selected to be at least the length of the antenna panel activation delay if it is expected that the wireless device may perform antenna panel activation to receive the transmission. The cellular base station may schedule the transmission to the wireless device using the selected scheduling offset, and may perform the transmission to the wireless device at the selected scheduling offset after scheduling the transmission to the wireless device.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE which uses a first antenna and a second antenna for communication with a first RAT. The apparatus determines that the second antenna is to be used for a procedure associated with a second RAT at a first time. The apparatus reduces a UE RI from an initial value to a reduced value for the communication with the first RAT at the first time based on the determination.

An electronic device includes a plurality of antenna modules, a first communication circuit communicating in a first communication scheme via at least one antenna module The electronic device also includes a second communication circuit communicating in a second communication scheme.

A radio apparatus includes a first antenna that transmits and receives a radio signal, a second antenna that receives a radio signal, a plurality of filters that acquire signals with mutually different frequencies from a received signal that is received by the second antenna, an amplification unit that is arranged in front of the plurality of filters and amplifies the received signal, and a control unit that controls whether or not the received signal is amplified by the amplification unit depending on a condition of radio communication by the first antenna and the second antenna.

Methods and apparatus for adaptively adjusting receiver operation for e.g., power optimization. In one embodiment, operation during diversity operation is adaptively adjusted. Diversity techniques consume significantly more power than non-diversity operation. However, the performance gain from receiver diversity is not always predictable. Consequently, in one embodiment, a device evaluates the overall performance gain contributed by diversity operation and, where the performance gain is insignificant or inadequate, the device disables diversity operation. In one implementation, the device can operate in a static single antenna mode, a dynamic single antenna mode and a dynamic multiple antenna mode.

There are provided systems, methods, and interfaces for optimization of the fronthaul interface bandwidth for Radio Access Networks and Cloud Radio Access Networks.

Multiple-Input Multiple-Output (MIMO) transmitters, receivers and transceivers are disclosed, as well as other associated devices, systems and methods. In particular, aspects and embodiments of the disclosure relate to MIMO transmitters, receivers and transceivers implemented as modules of relay devices for signals transmitted to and/or from base-stations and/or mobile-stations, in particular when such devices are implemented on mobile and/or aerial vehicles, and in particular for transmitting, receiving and/or forwarding wireless communication signals at frequencies in what is termed the “millimeter-wave band”. In such devices, a power control unit is configured to determine an energy availability measure and/or a power demand measure and, in response, cause a switching unit to connect a plurality of RF chains to a plurality of antenna elements in different states.

Embodiments of this application disclose a communication transmission method and a device. The method includes: receiving, by a terminal device, a minimum scheduling slot offset indicated by a network device; receiving, by the terminal device, indication information sent by the network device; or sending, by the terminal device, indication information to the network device, where the indication information is used to determine a first receiving state used by the terminal device to detect a PDCCH; and detecting, by the terminal device, the PDCCH by using the first receiving state when the minimum scheduling slot offset is greater than 0.
