An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: generate () a synchronization signal for transmission over one or more symbols, wherein the number of symbols is dependent on a subcarrier spacing.

Apparatus, method, and computer program

Beam configuration

Systems, methods, apparatuses, and computer program products for beam management reporting in connected mode discontinuous reception (C-DRX) are provided. One method includes configuring a user equipment (UE) in connected mode discontinuous reception (C-DRX) with a timer that determines at least one of when the UE monitors physical downlink control channel (PDCCH) from channel state information reference signal (CSI-RS) based beams or when the UE monitors PDCCH from synchronization signal block (SSB) based beams.

Methods and apparatus, including computer program products, are provided for beamforming control. In some example embodiments, there may be provided a method. The method may include providing, by a user equipment configured to include a plurality of antenna panels, capability information to a base station, the capability information including antenna panel information regarding the plurality of antenna panels; and providing, by the user equipment, antenna panel usage information to the base station, the antenna panel usage information indicative of which of the plurality of antenna panels are in at least one of an active transmit state or an active receive state. Related systems, methods, and articles of manufacture are also disclosed.

Facilitating user equipment beamforming control

Method, apparatuses, and computer program product for addressing random access responses with extended response windows. One method may include accessing, by a user equipment, a network by sending a random access channel preamble to a network element. The method may also include receiving, in response to the random access channel preamble, a random access response from the network element. The random access response provides an indication of which random access channel occasion in time within a span of one or a plurality of radio frames the random access response applies.

Receiving random access response with extended response window

Systems, methods, apparatuses, and computer program products for supporting a narrow serving beam in a hierarchical beam configuration. For example, certain embodiments may provide a UE that may receive, from a network node, information of a quasi co-location (QCL) configuration of self-contained, aperiodic, and/or semi-persistent tracking reference signals (TRSs) for sub-beams, where a source for one or more TRSs may be channel state information (CSI-RS) without repetition. In addition, the UE may determine these TRSs as self-contained, for which there are no associated periodic TRSs, if there is a TRS configured for an SSB sub-beam.

Supporting a narrow serving beam in a hierarchical beam configuration

According to an example embodiment, a method may include transmitting, by a wireless node in a wireless network, a sidelink synchronization signal (S-SSB) block, including a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), a physical sidelink broadcast channel (PSBCH), and a demodulation reference signal (DM-RS), wherein the demodulation reference signal is based on at least a sidelink demodulation reference signal initialization value for the sidelink synchronization signal block to provide sidelink priority-related information for the sidelink synchronization signal block.

Synchronization priority for sidelink wireless communications

According to an example aspect of the present invention, there is provided a method, comprising: receiving, by a first device from a second device, a message on a wireless medium indicating that the wireless medium has been reserved for at least one transmission from the first device to the second device by the second device detecting that the wireless medium is not occupied, based on a first beamwidth. The method further comprises determining, by the first device, a second beamwidth for performing the at least one transmission, selecting, by the first device on the basis of the received message, a method for the first device, from a set of at least two methods, to determine whether the wireless medium is occupied, determining, by the first device, based on the selected method for the first device whether the wireless medium is occupied, and in response to detecting that the wireless medium is not occupied, performing the at least one transmission by the first device.
