    摘要: This disclosure relates generally to wireless communications and, more particularly, to systems and methods for uplink signaling using blind channel estimation at a base station. In one embodiment, a method performed by a communication device, includes: associating a time slot with a data packet comprising a head portion and a tail portion, wherein the head portion comprises a communication device identifier and the tail portion comprises user data associated with the head portion; spreading the head portion into a first predetermined transmission format; spreading the tail portion into a second predetermined transmission format; and transmitting the spreaded head portion with the spreaded tail portion to a communication node, wherein the spreaded head portion comprises information to be used by the communication node for channel estimation and for decoding the tail portion to retrieve the user data.

    摘要: Methods, systems, and devices for a two-step random access procedure in mobile communication technology are described. An exemplary method for wireless communication includes receiving, by a network node, a random access message that comprises at least one of a radio network temporary identifier (RNTI), an identity of the wireless device, an establishment cause, uplink control information (UCI) or beam information, and transmitting, to a wireless device, a contention resolution message, wherein at least a portion of the random access message is modulated using a first modulation scheme selected from a modulation group that comprises binary phase shift keying (BPSK) and π/2-BPSK.

    摘要: Methods, systems, and devices for transmitter-side processing of preamble and reference signals are described. An exemplary method for wireless communication includes transmitting, by a wireless device, a message comprising modified symbols that are generated by performing a modification on baseline symbols. Another exemplary method for wireless communication includes receiving, by a network node, a message comprising modified symbols that are generated by performing a modification on baseline symbols. In an example, the message may be a random access message that is part of a 2-step random access channel (RACH) process or a contention-based physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) transmission.
