摘要： Aspects relate to sounding reference signal (SRS) time-domain bundling. Phase continuity may be maintained across SRS transmissions over multiple SRS occasions to enable a receiver to jointly process these SRS transmissions. In some examples, a user equipment may expect to be configured with SRS transmissions over multiple SRS occasions where SRS configurations for different SRS transmissions over different SRS occasions specify the same parameters. For example, a first SRS configuration for a first SRS transmission over a first SRS occasion may specify a first set of spatial relation information. In addition, a second SRS configuration for a second SRS transmission over a second SRS occasion may specify that same first set of spatial relation information. In this way, phase continuity may be maintained between the first SRS transmission over the first SRS occasion and the second SRS transmission over the second SRS occasion.

摘要： A method of wireless communication by a first sidelink UE measures multiple reference signals periodically transmitted by a second sidelink UE using multiple receive beams corresponding to reference signals in response to a beam failure declared by the first UE. The method also selects one of the reference signals that satisfies a condition. The method further includes notifying the second sidelink UE of the selected reference signal using a beam corresponding to the selected reference signal. Another method of wireless communications by a first sidelink UE includes periodically transmitting, to a second sidelink UE, multiple beam failure recovery (BFR) reference signals across multiple transmit beams. The method also includes receiving, from the second sidelink UE, an indication of a selected beam for communications between the first sidelink UE and the second sidelink UE. The method notifies the second sidelink UE of successful beam failure recovery.

摘要： This disclosure provides wireless communication methods, components, devices and systems for applying spectral masks and spectral flatness parameters in conjunction with transmission of millimeter wave (mmWave) signals in wireless communication networks. In some examples, in conjunction with transmission of an mmWave signal, a wireless communication device can apply a derivative spectral mask featuring transitional offset ranges that correspond to transitional frequency offset ranges of a spectral mask for a nominal carrier signal, scaled according to a ratio between a bandwidth of the mmWave signal and a bandwidth of the nominal carrier signal. In some examples, the derivative spectral mask can feature an in-band frequency offset range that is wider than a scaled width of an in-band frequency offset range of the spectral mask for the nominal carrier signal.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may use transmissions causing power density exposure (PDE) to nearby users. To reduce the PDE of an antenna module (e.g., below a maximum PDE threshold), the UE may implement a shielding strip around the antenna module. For example, the antenna module may include a substrate having a first surface and a set of antenna elements on the first surface. The shielding strip may enclose the set of antenna elements of the antenna module and extend away from the first surface above the antenna elements. The shielding strip may reduce PDE outside a field of view of the antenna module. Additionally, in some cases, the placement of the antenna module in the UE and the materials used for constructing the UE may further reduce PDE.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via medium access control (MAC) signaling, an indication to activate one or more transmission configuration indicator (TCI) states for the UE, wherein the indication triggers at least one of a measurement of a reference signal or a transmission of a measurement report for at least one TCI state of the one or more TCI states, wherein the reference signal or the transmission of the measurement report is triggered based on an association of a TCI state with the reference signal or the measurement report. The UE may receive the reference signal based on receiving the indication to activate the one or more TCI states. The UE may transmit the measurement report based on the indication triggering the transmission of the measurement report. Numerous other aspects are provided.

摘要： Wireless communications systems may support flexible waveform configuration for autonomous uplink transmissions. A base station may transmit broadcast signaling (e.g., a system information block (SIB)) indicating waveform configuration information for an autonomous uplink transmission by a user equipment (UE). In some cases, the broadcast signaling may include a waveform configuration field (WCF) that may indicate whether flexible waveforms for autonomous uplink are supported, may configure a waveform type, may indicate waveform configuration mapping rules, etc. As such, a UE may identify whether flexible waveform configuration for autonomous uplink is supported, and may determine waveform types for autonomous uplink transmissions based on waveform type configuration information from a base station (e.g., which may include an indication of whether flexible waveform configuration is supported, an indication of waveform type/scenario mapping rules, etc.), one or more LUTs, identified autonomous uplink scenarios, autonomous uplink transmission parameters, or some combination thereof.

摘要： This disclosure provides methods, components, devices and systems for channel access techniques in a multi-hop framework for ultra-high reliability (UHR). Some aspects more specifically relate to a transmission opportunity (TXOP) sharing mechanism according to which wireless communication devices can relay data frames along multiple hops within a same TXOP, a coordinated medium access scheme associated with relaying data frames between a root access point (AP) and a wireless station (STA) via multiple service periods, and various signaling mechanisms and frame formats according to which wireless communication devices can exchange or negotiate information associated with a coordinated medium access scheme. In some implementations, a coordinated medium access scheme may be associated with multiple time epochs (each associated with a service period) and differentiated channel access across the multiple time epochs may facilitate the relay with or without TXOP sharing within the associated service periods.

摘要： Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for channel access for wireless communications. One aspect provides a method for wireless communications at a user equipment (UE). The method generally includes obtaining a channel occupancy time (COT) structure information (COT-SI) message and obtaining at least one downlink control information (DCI) indicating multiple beams and listen before talk (LBT) scheme indications associated with the multiple beams. The method generally includes determining an LBT scheme to be used for transmission via each of the multiple beams based on the LBT scheme indications and the COT-SI message, and outputting signaling for transmission on each of the multiple beams based on the LBT scheme.
