Abstract: Techniques are described to configure a channel structure for a random-access procedure. For example, a wireless communication method includes communicates, by a first device, a channel structure to a second device, where the channel structure includes a first set of resources reserved for a first message (e.g., a preamble), a second set of resources reserved for a second message (e.g., a payload), or a time duration gap between the first set of resources and the second set of resources. The wireless communication method also includes receiving by the first device the first message and the second message at the configured first and second set of resources, respectively.

Abstract: Wireless communication includes a user equipment that transmits a message to a base station that includes a preamble and a payload corresponding to the preamble in a random access procedure. A parameter is determined based on the preamble, and a de-modulation reference signal (“DMRS”) sequence that is used for transmitting the payload is generated based on the parameter.

Abstract: Presented are systems and methods for radio network temporary identifier (RNTI). A wireless communication device may determine a RNTI. The wireless communication device may determine that a cyclic redundancy check (CRC) of a downlink control information (DCI) format is scrambled with the RNTI.

Abstract: A configuration of an initial access communication, such as the random access channel (“RACH”) process, is performed for initializing communications and/or synchronizing devices. The RACH format can be modified and configured for improved communications. For example, a RACH preamble can be modified based on multiple groups or measurements with reference signals. The preamble or format can be modified with a modification to the time duration.

Abstract: A method of wireless communication includes generating, based on a mapping rule, at least two reference signals and transmitting, by a wireless communication device, the at least two reference signals using different symbols in a transmit time interval. Another method of wireless communication includes transmitting, to one or more wireless devices in a wireless network, information indicative of a mapping rule that specifies a mapping between at least two random access reference signal transmissions from the one or more wireless devices.

Abstract: Methods, systems, and devices for power control for random access protocols in mobile communication technology are described. An exemplary method for wireless communication includes broadcasting, by a network node serving a cell, an indication of a transmit power level that is specific to the cell, wherein the indication is for use by a wireless device operating in the cell for a two-step random access procedure. Another exemplary method for wireless communication includes receiving, by a wireless device operating in a cell served by a network node, an indication of a transmit power level that is specific to the cell for use in a two-step random access procedure, and transmitting, at the transmit power level, a first message of the two-step random access procedure.

Abstract: Methods, systems, and devices for the design of symbol-group based spreading schemes are described. An exemplary method for wireless communication includes transmitting, by a terminal, a first spread signal that is generated by spreading a first group of N data symbols using a first set of N sequences, where N is a symbol-group length, L is a spreading length, each of the first set of N sequences is from an orthogonal spreading sequence set that comprises L sequences, and each of the L sequences is of length L. Another exemplary method for wireless communication includes transmitting, by a network node, an indication of a first set of N sequences, and receiving a first spread signal comprising a group of N data symbols spread using the first set of N sequences.
