  • Patent number: 11968137
    Abstract: An apparatus may be configured to communicate at least one pilot signal with another apparatus according to a first configuration, at least one of a lower frequency density or a higher time density being indicated by the first configuration than a second configuration for a type of pilot signal that includes the at least one pilot signal. The apparatus may be further configured to communicate with the other apparatus based on the at least one pilot signal. Another apparatus may be configured to receive, from a base station, spatial relationship information or transmission configuration indicator (TCI) state information corresponding to a directional beam at the UE for communication on a channel. The apparatus may be further configured to apply the directional beam for communication with the base station on another channel in a sub-6 gigahertz (GHz) frequency band.

  • Patent number: 11917618
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive an indication of a first set of resources for feedback and an indication of a second set of resources for feedback, where the second set of resources are associated with a smaller quantity of cyclic shifts than the first set of resources. Accordingly, the mobile station may transmit feedback on either the first set of resources or the second set of resources based at least in part on a distance associated with the feedback. As an alternative, the mobile station may compute a timing advance associated with transmission of feedback. Accordingly, the mobile station may feedback that is shifted in time according to the timing advance. Numerous other aspects are described.

  • Patent number: 11902800
    Abstract: Example aspects include a method, apparatus and computer-readable medium of wireless communication at a base station of a mobile network, comprising transmitting system information corresponding to an aerial cell of the mobile network or a cell having at least one aerial sector being formed by one or more uptilt beams of the base station. The aspects further include performing, according to the system information, a random access channel (RACH) procedure with an aerial user equipment (UE). Additionally, the aspects include establishing, via the aerial cell or the at least one aerial sector, a communications link with the aerial UE.

  • Patent number: 11825535
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may establish a PC5 unicast link with a second UE. The UE may transmit, to a second UE in a PC5 radio resource control (RRC) message, capability information that includes an indication that the first UE is an unmanned aerial vehicle (UAV). Numerous other aspects are described.

  • Publication number: 20230217428
    Abstract: A wireless communication device can flexibly change subcarrier spacing (SCS) and/or cyclic prefix (CP) in wireless communication. The wireless communication device can transmit, in a first sidelink resource of a sidelink resource pool, a first sidelink transmission using a first configuration of suhcarrier spacing (SCS) and cyclic prefix (CP). The wireless communication device can further transmit, in a second sidelink resource of the sidelink resource pool., a second sidelink transmission using a second configuration of SCS and CP, the second configuration being different from the first configuration in terms of at least one of an SCS or a CP. The techniques allow more efficient switching between SCS and CP configurations withing a resource pool, in the same bandwidth part.

  • Publication number: 20230074011
    Abstract: Aspects include systems, methods, devices, and non-transitory processor readable storage mediums for managing a broadcast signal of an apparatus for wireless communication. Various aspects may enable an apparatus to send a message using either omnidirectional transmissions or beamformed transmission based on whether the altitude of the apparatus meets an altitude threshold. In some implementations and aspects, the processor of the apparatus may determine a type of the message and may select the altitude threshold based on the determined message type. In some implementations and aspects, the processor of the apparatus may send the message using beamformed transmissions in response to determining that the message is intended for reception by a certain type of second apparatus.
