This provides a spatial multiplexing method and apparatus, to introduce WLAN sensing into a conventional spatial multiplexing mechanism and improve communication efficiency. The method includes: An AP sends a first request message to a first station and a second station, to request to measure channel quality in one or more sensing beam directions in a first SP; the AP sends a second request message to a third station and a fourth station, to request to measure channel quality in a communications beam direction in a second SP; the first station, the second station, the third station, and the fourth station separately perform measurement and report respective first measurement results; and the AP receives the first measurement results of the stations, and determines, based on the first measurement results, whether to perform spatial multiplexing on the first SP and the second SP.

This disclosure relates to techniques for performing wireless communications including exchanging information related to capability of processing reference signals. A user equipment device may provide capability information to a network. The capability information may indicate a number of reference signal resources that the user equipment device can process in a slot or other defined period of time. The user equipment device and the network may share a common set of definitions, counting rules, and approaches for interpreting the capability information. The network may configure reference signals for the user equipment device.

Embodiments of the present disclosure provide methods and apparatus for detecting interference in radio carrier band. A method performed at a network node may comprise: receiving, from a terminal device, a first report about channel state of a first frequency range, and a second report about channel state of a second frequency range; and determining whether the terminal device is interfered in any of the first frequency range or the second frequency range, based on a comparison between the channel state of the first frequency range and the channel state of the second frequency range. According to embodiments of the present disclosure, the deterioration of channel state in a frequency range caused by interference may be shown and recognized via the comparison result.

A method for transmitting a reference signal in a multi-antenna system is provided. The method includes: selecting at least one orthogonal frequency division multiplexing (OFDM) symbol in a subframe containing a plurality of OFDM symbols; allocating a channel quality indication reference signal (CQI RS) capable of measuring a channel state for each of a plurality of antennas to the selected at least one OFDM symbol; and transmitting the CQI RS, wherein the CQI RS is allocated to an OFDM symbol which does not overlap with an OFDM symbol to which a common reference signal to be transmitted to all user equipments in a cell or a dedicated reference signal to be transmitted to a specific user equipment in the cell is allocated.

Beamforming monitoring apparatus and method are disclosed. The method, comprises receiving (300) parameter data of radio connections between transceivers of a radio access network, the parameter data comprising transmission direction of the beams used in transmission and quality indicators related to transmitted beams; organising (302) data into one or more layers based on parameter data and connections at a given time resolution; receiving (304) a selection of layers at a given time instant; receiving (306) a selection of a view type; and controlling (308) displaying of the selected layers of the given time instant using the selected view type.

An Orthogonal Frequency Division Multiplexing (OFDM) transmitter generates OFDM multiple-access signals with low Peak-to-Average-Power Ratio (PAPR). A code-division multiplexer arranges original data symbols from different data streams inside each length-N symbol block, which is spread by a Discrete Fourier Transform (DFT) spreader. The arrangement of the original data symbols configures the DFT spreader to spread each original data symbol into a predetermined spread-DFT code division multiple access channel. The resulting DFT-spread data symbols are mapped to OFDM subcarriers, and an inverse discrete Fourier transform (IDFT) operates on the DFT-spread data symbols to generate an OFDM transmission signal having low PAPR.

A method of wireless communication performed by a user equipment (UE) includes receiving one or more configuration messages indicating configuration of the UE with a first component carrier (CC) and at least a second CC for a first subscription corresponding to a first subscriber identity module (SIM) of the UE. The method further includes performing one or more operations associated with a second subscription corresponding to a second SIM of the UE during a time interval. During the time interval, communication by the first subscription using the second CC is avoided based on a first throughput associated with the first CC exceeding a second throughput associated with the second CC.

A method for assisting the adaptation of a signal from a first node to a second node is provided. The first node communicates with the second node in a wireless communication system over a radio link. The second node has a codebook comprising a set of possible information alternatives for assisting the adaptation of a signal received from the first node. The second node may select an information alternative from the codebook and send it to the first node to assist the first node in adapting the signal. The first node is configured with a number of subsets, each comprising a part of the possible information alternatives. The first node requests that the second node restrict the selection of information alternatives to one of the subsets, and in response, receives an information alternative from the second node that is selected from among the subsets configured according to the configuration request.

A wireless transmit/receive unit (WTRU) may be configured to receive configuration information associated with a first transmission configuration indicator (TCI) state group and a second TCI state group. The WTRU may be configured to report first respective measured downlink received power values and first respective determined power reduction values. The WTRU may be configured to report second respective measured downlink received power values and second respective determined power reduction values. The WTRU may be configured to receive an indication of the first TCI state group via a downlink transmission. The WTRU may be configured to determine a first TCI state from the first TCI state group based on downlink received power information and power reduction information. The WTRU may be configured to send an uplink transmission based on the first determined TCI state.

Embodiments of the present disclosure describe methods, apparatuses, and systems for enhanced control signaling using full-duplex communication in wireless communication networks. A base station may schedule a first user equipment (UE) for primary access to a set of time-frequency resources in a first communication direction (e.g., uplink or downlink). The base station may additionally schedule a second UE for secondary access to the same set of time-frequency resources in a second communication direction that is the opposite of the first communication direction. The secondary access may be used to communicate supplemental control information, such as a channel quality indicator (CQI) and/or modulation and coding scheme (MCS) feedback, hybrid automatic repeat request (HARQ) feedback, and/or multiple input multiple output (MIMO) feedback (e.g., including a rank indicator (RI) and/or a pre-coding matrix indicator (PMI). Other embodiments may be described and claimed.
