Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of beams, for which a corresponding uplink beam indication is not configured, associated with a set of transmit-receive points (TRPs) based at least in part on at least one of a downlink control information (DCI) configuration, a transmission configuration indicator (TCI) codepoint mapping, a control resource set (CORESET) configuration, or a TRP index, wherein the set of beams includes a sounding reference signal (SRS) beam or a physical uplink control channel (PUCCH) beam. The UE may communicate with the set of TRPs using the set of beams based at least in part on determining the set of beams. Numerous other aspects are provided.

Some aspects described herein relate to receiving, in a configuration, a slot format indication, wherein the slot format indication includes directional information indicating spatial directions associated with communications based on the slot format, determining, for a slot indicated by the slot format indication and based on the directional information, the spatial direction, and communicating, within the slot and based on the spatial direction, with one or more nodes.

A method of a user equipment (UE) in a wireless communication system is provided. The method comprises receiving, from at least one transmission and reception point (TRP) of a group of (N) TRPs, channel status information (CSI) configuration information, determining a CSI report based on the CSI configuration information, identifying, based on the configuration information, one or more TRPs of the group of (N) TRPs to transmit the determined CSI report, and transmitting, to the one or more TRPs, the determined CSI report over an uplink channel. The determined CSI report includes a TRP indicator for selecting (M) TRPs of the group of (N) TRPs, and CSI for each of the selected (M) TRPs, wherein N is greater than one, and wherein M is greater or equal to 1, and less or equal to N.

The present inventive concept relates to a multi-antenna channel estimation apparatus and method for performing beamforming in a communication system in which only single channel estimation is possible, and relates to a channel estimation apparatus and method for beamforming in which the transmitter generates pilot signals based on the Zadoff-chu sequence and transmits the generated pilot signals to the receiver, the receiver estimates a channel based on the pilot signal, and feeds back information for beamforming to the transmitter based on the estimated channel information, and it is configured to enable beamforming by converting and setting the signal phase for each antenna according to the feedback received from the transmitter.

Embodiments herein disclose a method for selecting a pilot pattern for an optimal channel estimation in a wireless network by a UE. The method includes: receiving a specified pilot pattern from a base station (BS); determining at least one channel parameter from the received specified pilot pattern, wherein the at least one channel parameter comprises a delay, a Doppler, a Demodulation Reference Signal (DMRS), a sounding reference signal (SRS), and a signal to noise ratio (SNR); estimating a minimum number of pilots required using the at least one determined channel parameter; and determining an optimal pilot pattern using a channel coefficient and the estimated minimum number of pilots, wherein the optimal pilot pattern is used for the optimal channel estimation.

[Object] To provide a communication device that enables degradation in the quality of communication between a base station device and a terminal device to be avoided when a sidelink channel is set. [Solution] There is provided a communication device including: a control unit configured to allocate a predetermined gap to a boundary of a resource of a channel to be used in inter-device communication with a resource other than the resource of the channel in a communication system in which signals from different transmission sources are mixed and placed.

The application relates to maintaining time-synchronization of a wireless connection between a network access node and a client device. The wireless connection may be configured for services with latency constraints. In one example, based on an expiry of a time alignment timer for the client device, the network access node transmits a control message to the client device. The control message instructs the client device to transmit a response signal to the network access node. The response signal can be used by the network access node to determine the timing advance for the wireless connection and adjust the timing advance.

Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating an Enhanced Directional Multi-Gigabit (DMG) (EDMG) Physical Layer Protocol Data Unit (PPDU). For example, an EDMG wireless communication station (STA) may be configured to communicate an EDMG PPDU including a Channel Estimation Field (CEF) and/or a pilot sequence, which may be configured for an OFDM mode.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station and/or a user equipment may determine a time domain resource pattern for a set of demodulation reference signals (DMRSs), wherein the set of DMRSs is included in a Type-B physical downlink shared channel (PDSCH). A base station may transmit, and the user equipment may receive, the set of DMRSs using a set of resources determined based at least in part on the time domain resource pattern. Numerous other aspects are provided.

In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications at a user equipment (UE) for receiving a downlink control indicator (DCI) from a network entity; and configuring at least one physical uplink shared channel (PUSCH) transmission based on a determination that the DCI does not include the scheduling request indicator (SRI) field.
