    Abstract: A wireless device receives one or more radio resource control (RRC) messages comprising random access (RA) configuration parameters of a bandwidth part (BWP) of a cell, indicating one or more random access channel occasions (ROs) multiplexed in frequency domain and a physical resource block (PRB) offset with respect to a first PRB of the BWP. The wireless device may further determine frequency resource indexes of the one or more ROs, in an increasing order starting from a first frequency resource index of the first RO. The wireless device may transmit a preamble via a second RO selected from the one or more ROs and determine a frequency resource index of the second RO based on the frequency resource indexes determined based on the frequency index offset applied to the first RO. The wireless device may receive, based on an RA identifier, a response to the preamble.

  • Publication number: 20240014946
    Abstract: A base station may cancel or delay (e.g., pre-empt) a transmission from a wireless device by sending a pre-emption indication to the wireless device. Based on receiving the pre-emption indication, the wireless device may cancel the transmission, store an indication associated with the cancelled transmission, and/or store the cancelled transmission in a data buffer. The base station may request transmission of the data unit (e.g., at a later time) by transmitting another indication.

  • Patent number: 11864714
    Abstract: In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.
