There is disclosed a method of operating a radio node (10) in a radio access network, the method comprising transmitting feedback signaling utilising a feedback resource range, wherein transmitting the feedback signaling comprises a transmitting a transmission size indication indicating a size of the feedback signaling. The disclosure also pertains to related devices and methods.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication associated with phase noise characteristics of the UE. The UE may receive an indication of pilot allocation sizes, for different data modulation and coding schemes (MCSs) for communications, of frequency-domain contiguous pilots for phase noise mitigation based at least in part on the indication associated with the phase noise characteristics of the UE. Numerous other aspects are described.

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.

This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to signaling in a trigger frame to support distributed transmissions via distributed resource units (dRUs). In some implementations, an access point (AP) may transmit a trigger frame soliciting a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU) from a wireless station (STA), where the trigger frame carries RU allocation information identifying a distributed resource unit (dRU) allocated for the STA and carries tone mapping information indicating a selected spreading bandwidth design for the wireless channel or subchannel. The AP can support channel puncturing by selecting a particular spreading bandwidth design that controls how dRUs are mapped to non-contiguous tones spanning respective spreading bandwidths.

Aspects of the present disclosure provide techniques for signaling PDCCH with relevant QCL relationships for CE for a UE to use to process a multi-TRP transmission sent using disjoint RBs.

This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to trigger frame and physical layer convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, an access point (AP) may transmit a trigger frame soliciting a trigger-based (TB) PPDU from a wireless station (STA), where the trigger frame carries RU allocation information indicating a number (N) of tones allocated for the STA and carries tone distribution information indicating whether the N tones are allocated for a contiguous transmission or a distributed transmission. In some other implementations, an AP or a STA may transmit a PPDU carrying distributed signaling information indicating whether the PPDU is transmitted as a contiguous transmission or a distributed transmission.

Techniques for measuring CSI (Channel State Information) based on beamformed CSI-RS having reduced overhead are discussed. One example embodiment configured to be employed in a UE (User Equipment) comprises a memory; and one or more processors configured to: process higher layer signaling indicating one or more CSI-RS resources associated with a plurality of REs (Resource Elements) comprising a RE for each CSI-RS resource for each of one or more CSI-RS APs (Antenna Ports) in each of a plurality of continuous PRBs (physical resource blocks); process additional higher layer signaling comprising one or more CSI-RS parameters that indicate a subset of the plurality of REs associated with a beamformed CSI-RS transmission; decode one or more CSI-RSs from the indicated subset; and measure one or more CSI parameters based on the decoded one or more CSI-RSs.

A communication apparatus in the present disclosure comprises an AID generator, a Trigger frame generator, and a wireless transmitter/receiver. When a Trigger Type in a trigger frame is an RA trigger, the AID generator (103) generates, as information for an AID12 subfield, information that is different from an AID. The Trigger frame generator (104) generates a RA variant Trigger frame when the Trigger Type in the trigger frame is an RA trigger, and sets, in the AID12 subfield included in the RA variant Trigger frame, the information output from the AID generator (103). The wireless transmitter/receiver (106) transmits the Trigger frame, generated by the Trigger frame generator (104), to a terminal (200).

The disclosure relates to a 5G or 6G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The disclosure proposes a method and an apparatus for initial access of a reduced capability terminal. The method comprises receiving, from a base station, information on an initial bandwidth part (BWP) for the redcap terminal; and transmitting and receiving, to or from the base station, data on the initial BWP for the redcap terminal, wherein the information on the initial BWP for the redcap terminal is included in a system information block 1, and wherein the information on the initial BWP for the redcap terminal includes information on a frequency location of the initial BWP for the redcap terminal, subcarrier spacing information and cyclic prefix information of the initial BWP for the redcap terminal.

A user equipment, a method for controlling the user equipment and a network side device are provided in the present disclosure. The method includes transmitting broadcast-type signals and channels to the user equipment through a dedicated resource unit so that the user equipment can access a network; wherein the dedicated resource unit is only configured to transmit the broadcast-type signals and channels, and is continuous in a frequency domain and a time domain, wherein the broadcast-type signals and channels comprise at least one of a synchronization signal, a broadcast channel and a common control channel, wherein transmitting the broadcast-type signals and channels through the dedicated resource unit comprises: transmitting the broadcast channel and/or the common control channel to the user equipment by using a preset broadcast reference signal. The present disclosure can control the user equipment to access the network.
