The body includes a rear cover, a transparent front cover, a lamp board, a number of LED light sources, a driving circuit board and a fixing member. The LED light sources are mounted on the lamp board facing the front cover, wherein the LED light sources are visible from an outside of the transparent front cover when they are lit. The driving circuit board is electrically connected to the socket and the lamp board, and is configured for driving the LED light sources to emit light beams. The fixing member is configured for fixing the rear cover, the driving circuit board and the lamp board together.
摘要:
Techniques are discussed herein identify transmission strategies and to communicate those identified transmission strategies in a transparent communication environment. In some examples, a user equipment (UE) may identify a new transmission strategy for a downlink channel different from a current transmission strategy for the down link channel. The UE may transmit a channel state information (CSI) message that includes an indication of the new transmission strategy identified by the UE. In some examples, a base station may identify the new transmission strategy for the downlink channel. The base station may transmit a codebook subset restriction (CSR) indicator that includes an indication of the new transmission strategy identified by the base station. In some examples, the UE may modify its feedback strategy based on the new transmission strategy.

Aspects of the disclosure relate to radio access networks with a capability to dynamically reconfigure a number of transmission-reception points (TRPs) in a single-frequency network (SFN) based on channel measurements. In one example, a mobile device receives a configuration message including a plurality of transmission configuration indicator (TCI) states, and potentially further including an indication identifying one or more of the TCI states as main TCI states. The message may further include an indication that it includes the plurality of TCI states. The UE receives a downlink traffic channel and demodulates the traffic channel based on only a subset of the TCI states (e.g., the main TCI state (s)). The UE further measures one or more channel parameters corresponding to each TCI state of the plurality of TCI states, and transmits a channel state information report based on the channel parameters. Other aspects, embodiments, and features are also claimed and described.

The described techniques relate to improved methods, systems, devices, or apparatuses that support communication schemes for small cyclic delay diversity (SCDD) reference signals. A base station may transmit a control message comprising at least one channel state information (CSI) configuration parameter to a user equipment (UE). The UE may identify a time offset between a plurality of virtual antennas of the base station based at least in part on the CSI configuration parameter. The UE may perform measurements of a plurality of CSI reference signals (CSI-RSs) transmitted by the base station and associated with the virtual antennas. The UE may transmit a feedback message based at least in part on the determined time offset and the measurements of the CSI-RSs.
摘要:
Methods, systems, and devices for wireless communication are described that support a low peak-to-average power ratio (PAPR) precoded reference signal design for multiple-input, multiple-output (MIMO) transmissions. A user equipment (UE) may identify multiple sets of symbols associated with different reference signal waveforms, where each reference signal waveform may be associated with a low PAPR. In some cases, different single-carrier reference signal waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM) for a transmission on a single antenna. However, the addition of single-carrier waveforms through FDM for a transmission via an antenna may result in an uplink transmission having a high PAPR (e.g., as compared to single-carrier waveforms). The UE may reduce the PAPR of the uplink transmission by multiplexing the reference signal waveforms in the time domain (e.g., using time division multiplexing (TDM)).
摘要:
The present invention provides a method and apparatus for indicating downlink channel measurement and a method and apparatus for performing channel measurement. The method for indicating downlink channel measurement comprises: receiving information on interferes of a user equipment; generating, based on downlink subframe configuration information, a downlink channel measurement indication for each of possible combinations of the interferers, wherein the channel measurement indication is adapted to indicate a subframe group to be measured by a user equipment; and sending the downlink channel measurement indication to the user equipment so as to indicate the user equipment to perform corresponding downlink channel measurement. According to embodiments of the present invention, the subframe groups that are required to be measured by the user equipment may be determined with respect to possible combinations of interferers corresponding to different levels of interference. Thus, the user equipment may perform channel measurement for respective subframe groups. Therefore, the channel quality as determined in such way will be more accurate and reliable and better match the actual channel condition. Moreover, it also provides a possibility for the serving node to perform the scheduling more accurately and effectively.
