Disclosed are an electronic device and a method of transmitting a wireless signal thereof. The electronic device includes: a housing; a first antenna configured to form a first part of the housing; a second antenna configured to form a second part of the housing; and at least one processor including a first transmission terminal and a second transmission terminal connected to the first antenna and the second antenna, respectively, wherein the at least one processor is further configured to identify a strength of at least one of a transmission signal and a reception signal when transmission of a wireless signal is requested, and control at least one of a phase and a strength of wireless signals output through the first transmission terminal and the second transmission terminal according to a result of the identification. Various other embodiments are possible.

A method of operating a wireless communication device (102) in a wireless communication system (100) comprises transmitting a control signal to a node (102) of the wireless communication system (100). The control signal is indicative of a mapping between at least one antenna port (5031-5033) and at least one antenna panel (5023, 5024) of the wireless communication device (102).

The present disclosure relates to devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device, which comprises at least one antenna array each comprising a plurality of antenna elements may perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements (with corresponding RF chains) of one or more antenna arrays. The wireless device may generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling. The wireless device may then send the PHR report to a base station in communication with the wireless device.

Various embodiments disclosed herein provide for a beam recovery when there has been a partial control channel failure. Transient obstructions, and other interference effects can cause the failure of a beam pair link which can comprise a transmit beam and a receive beam associated with respective antennas on a transmitter and receiver. A group of control channels (downlink control channels) (configured as a control resource set CORESET) on a group of beam pair links can be associated with a group of uplink control resources (Physical Uplink Control Channel resources). When a subset of the CORESET group fails, the user equipment (UE) device can find another PUCCH that is associated with a working CORESET to send an indication to the network about the failure. When the network receives the indication, the network can switch the failed CORESET to a new beam pair link.

The disclosure relates to a method (20) performed in a network node (5, 9, 7) of a communication system (1) for muting antenna elements of an active antenna system (11). The method (20) comprises determining (22), based on a priori information relating to performance of the communication system (1), an antenna element separation between one or more pairs of active antenna elements of at least a subset of all active antenna elements of the active antenna system (11); and muting (24) at least one antenna element such that the determined antenna element separation is obtained between each of the one or more pairs of active antenna elements of at least the subset of all active antenna elements. A corresponding network node (5, 9, 7), computer programs and computer program products are also disclosed.

Switching between and/or combining various multi-transceiver wireless communication techniques based on a determined characteristic of a network or a wireless link is described herein. As an example, a characteristic such as signal to noise ratio (SNR), multi-path scattering, available bandwidth, or the like, can be determined. The characteristic can then be compared with suitable thresholds for various multi-transceiver communication techniques, such as MIMO, multi-channel concatenation, channel diversity, and so on. Based on a comparison of the characteristic and the thresholds, a suitable multi-transceiver technique can be selected and implemented for the wireless link. Accordingly, a network can provide increased data rates and/or channel quality from a multi-transceiver technique that is most suited to prevailing conditions of the wireless network/link.

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of spatial adaptation for energy saving. The method comprises: receiving, at a first device from a second device, a change indication indicating at least one antenna port of which at least one antenna element is changed. The antenna port is active before and after the change. The method further comprises performing at least one of a measurement of at least one reference signal or a reception of a physical channel in consideration of the at least one antenna port. In this way, the first device may be informed about impact of spatial adaptation of the second device and is able to adapt the impacted channel state information measurement and/or reporting. As such, energy saving can be achieved.

Embodiments herein relate to method performed by a radio network node for handling communication in a wireless communication network. The radio network node dynamically applies different muting patterns for muting an active component of one or more antenna branches of the radio network node and/or of one or more antenna panels of the radio network node, wherein the different muting patterns are associated with one or more types of physical channels used for communicating and/or a communication parameter related to one or more UEs. The radio network node performs a communication using the dynamically applied different muting patterns.

A method includes: controllably configuring at least one antenna diversity switch in a wireless device to establish conductive paths between at least one transceiver of the wireless device and multiple antennas each disposed at a respective one of a multiple areas of a housing of the wireless device; and routing signals between the at least one transceiver and the multiple antennas, via the at least one antenna diversity switch, such that a signal is routed to either of at least two of the multiple antennas disposed at a first end area of the multiple areas of the housing of the wireless device or to either of at least two other antennas disposed at a second end area of the multiple areas of the housing of the wireless device.
