The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and to an apparatus for transmitting an SRS in a multi-antenna system. The method comprises the steps of: acquiring specific information for discriminating a first antenna group and a second antenna group from among a plurality of antennas, wherein said first antenna group includes one or more antennas which are set to a turned-on state to perform communication with a base station, and said second antenna group includes one or more other antennas which are set to a turned-off state; transmitting an SRS to the base station if a predetermined condition is satisfied, under the condition that the second antenna group is set to the turned-off state; and setting the second antenna group to a turned-off state after the transmission of the SRS.

Systems and methods for providing improved cell-edge antenna performance are disclosed. The system can use various signal quality indicators (SQIs) for each user equipment (UE) on a particular wireless base station (WBS) or network. When one or more of these metrics reaches a first predetermined value for a particular UE, the WBS or the UE can decide to activate a diversity receive (Rx) antenna on the UE to improve reception. If one or more of these metrics continues to degrade to a second predetermined value, however, the WBS or the UE can deactivate the diversity Rx antenna and activate a primary Rx antenna. Deactivating the diversity antenna when signal quality/strength is poor can improve reception by reducing interference between the diversity Rx antennas. Disabling the diversity Rx antenna when signal quality/strength is poor can also decrease the number of retransmission requests from each UE, reducing traffic on the WBS.

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.

An operating method of an electronic device according to various embodiments may include: receiving a reference signal from a base station via a plurality of antennas; acquiring path loss values respectively corresponding to the antennas, based on the reference signal; determining at least two antennas among the antennas, based on frequency band information received from the base station; acquiring a ratio for the path loss values corresponding to the determined at least two antennas; and transmitting a signal via the at least two antennas, based on the acquired ratio.

Control for multi-panel user equipment (MPUE) activation may be performed by both the MPUE and a base station. The MPUE may have at least a first panel and a second panel. The MPUE may send to the base station, a request to change an activation status of at least one panel of the MPUE. The base station may transmit a response indicating whether the request has been approved. The MPUE may change the activation status of the panel according to the response. Conversely, the MPUE may receive a command from the base station to change an activation status of at least one panel of the MPUE. The MPUE may determine whether to follow the command or override the command. The MPUE may transmit a response indicating whether the MPUEUE has followed the command or overridden the command.
