Abstract: The present invention discloses a method for indicating pilot state, a radio network controller. The method includes: acquiring, by an RNC, state information of a scheduled non-precoded pilot, where the state information of the scheduled non-precoded pilot indicates activated state or deactivated state of the scheduled non-precoded pilot; and sending, by the RNC, 4Tx MIMO mode configuration signaling to a UE, where the configuration signaling carries the state information of the scheduled non-precoded pilot, so that the UE acquires state of the scheduled non-precoded pilot according to the state information of the scheduled non-precoded pilot when being configured to 4Tx MIMO mode. The method for indicating pilot state and the radio network controller according to embodiments of the present invention can reduce physical-layer signaling overheads and reduce a delay in acquiring state of a scheduled non-precoded pilot by the UE in 4Tx MIMO mode.

Abstract: The present invention provides a method, network side device and user equipment of variable bandwidth. The method includes: configuring a first type carrier and a second type carrier, wherein a chip rate of the first type carrier is 3.8 Mcps, a chip rate of the second type carrier is P*3.84 Mcps, and P is smaller than 1 and larger than 0; using the first type carrier and/or the second type carrier for communication. In this way, since the chip rate of the second type carrier is low and occupied bandwidth is small, the second type carrier may be suitable for non-standard bandwidth, thus utilization efficiency of bandwidth may be improved and waste of the bandwidth may be reduced.

Abstract: This application discloses a carrier switching solution for multi-carrier communication. A network device sends configuration information to a terminal. The configuration information includes first uplink carrier information and second uplink carrier information. The first uplink carrier information indicates that a first uplink carrier is an SRS switching-from uplink carrier.

Abstract: An electronic device includes a light guide plate including three grating parts. A first grating part is configured to receive the emitted light through a light incident surface of the first grating part, diffract the emitted light to form a first light, and enable the first light to enter a second grating part. The second grating part is configured to form, based on the first light, a second light propagated in the second grating part, and form, based on the second light, a third light entering a third grating part. The third grating part is configured to form, based on the third light, a fourth light propagated in the third grating part, form an emergent light based on the fourth light, and enable the emergent light to be emitted through a light emergent surface of the third grating part and enter a cover plate.
