Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to schedule the wireless nodes (e.g., access points and/or stations) operating within the cluster. For example, stations may be scheduled across basis services sets of the access points for a downlink transmission and/or an uplink transmission.

An uplink data scheduling method and device are provided. The method comprises: a terminal device receiving a first signalling sent by a network device, wherein the first signalling comprises beam information of M beams, and M is a positive integer; the terminal device carrying out carrier sensing on the M beams in sequence according to the first signalling; and the terminal device selecting, according to the sensing result, one beam of the M beams to transmit an uplink channel to the network device.

Disclosed are methods, apparatus and systems for reliable information transmission for Ultra-Reliable Low Latency Communication (URLLC) in both (Long Term Evolution) LTE-Advanced and New Radio (NR) systems. In some embodiments, a method includes detecting a downlink transmission on a set of downlink resources, and transmitting a set of signals on a set of uplink resources, which are associated with the set of downlink resources, and where portions of a first and second of the set of signals are identical. In other embodiments, a method includes determining, based on a transmission time, that one or more of a plurality of time units comprises a reference signal, identifying a reference pattern for transmission based on the determining, and transmitting a set of signals comprising the reference pattern during the plurality of time units.

Disclosed in various embodiments are a method for configuring a bandwidth part in a wireless communication system, and a device for supporting same. As one specific example, disclosed in various embodiments are: a method by which a device identifies, confirms, or configures an initial bandwidth part in a wireless communication system; and a device for supporting same.

The present invention relates to a wireless communication system and, specifically, to a method and an apparatus therefor, the method comprising the steps of: receiving scheduling information for a plurality of consecutive transmission time intervals (TTIs); and transmitting data on the basis of the scheduling information, wherein the scheduling information includes a combination of a first symbol index and the number of consecutive symbols, the data is transmitted from a starting symbol of a first TTI (starting TTI) among the plurality of consecutive TTIs to an ending symbol of the last TR on the basis of the scheduling information, and the index of the starting symbol and the index of the ending symbol are determined on the basis of the combination of the first symbol index and the number of the consecutive symbols.

A computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE). configure the UE for NR communication. The instructions cause the UE to decode sidelink control information (SCI). The SCI includes scheduling information and priority information. The scheduling information indicates time resource assignment and frequency resource assignment for sidelink data communications using a physical sidelink shared channel (PSSCH). The instructions further cause the UE to detect that a transmission (Tx) of a first set of physical sidelink feedback channels (PSFCHs) would overlap in time with a reception (Rx) of a second set of PSFCHs. The first and second sets of PSFCHs include sidelink feedback control information for the sidelink data communications. The instructions further cause transmission of at least one PSFCH from the first set of PSFCHs or the second set of PSFCHs based on the priority information.

A wireless device receives one or more radio resource control messages comprising configuration parameters for a cell. The configuration parameters indicate a plurality of coreset groups corresponding to a plurality of transmission and reception points (TRPs). Each coreset in the plurality of coreset groups is associated with a transmission configuration indicator (TCI) state. A coreset group of the plurality of coreset groups is selected for a radio link monitoring of the cell. The selection is in response to the coreset group comprising a coreset with a pre-defined index value. One or more reference signals are monitored based on one or more TCI states of one or more coresets of the coreset group.

Methods, systems, and devices for wireless communications are described. A base station may identify a listen-before-talk (LBT) procedure to use for transmitting a downlink signal to a user equipment (UE) on a shared radio frequency spectrum band. The LBT procedure may be a group LBT procedure associated with a first set of contention window durations or an individual listen-before talk procedure associated with a second set of contention window durations. The base station may determine a contention window duration corresponding to the identified LBT procedure, perform the identified LBT procedure using the determined contention window duration, and transmit the downlink signal to the UE based on the performed LBT procedure.

Aspects provide a mechanism for activating a secondary serving cell (SCell) in a wireless communication network supporting a multi-cell transmission environment. In some examples, a scheduled entity (e.g., a UE) in a connected mode with a primary serving cell (PCell) may synchronize with the SCell to activate the SCell for multi-cell communication with the PCell and the SCell. To enable synchronization with the SCell, the PCell may trigger communication and processing of one or more reference signals between the scheduled entity and the SCell.

Methods and apparatus related to HARQ feedback, e.g. delayed HARQ ACK/NACK, and uplink control information (UCI) multiplexing, in unlicensed spectrum are described. A base station transmits an UCI request to a UE, including: a request for ACK/NACK feedback corresponding to a set of HARQ identified processes, a request for channel state information report, and/or a scheduling request. The UCI request includes information which is used, by the UE, in determining the time and air link resources on which to send the UCI. The HARQ processes are communicated in a first Channel Occupancy Time (COT), while the ACK/NACK feedback is communicated in a later COT.
