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 related to applying a spreading code to reference signals are described. In one exemplary aspect, a method for wireless communication includes receiving a message indicating a set of control options available to the mobile device for data transmissions. The method includes selecting a spreading code sequence from a number of spreading code sequences, wherein the spreading code sequence corresponds to a control option in the set of control options, wherein the number of spreading code sequences is greater than a length of each of the spreading code sequence, and wherein the spreading code sequences are generated using a method when the length of each of the spreading code sequences is greater than or equal to a value. The method also includes generating a plurality of reference signal symbols using the spreading code sequence, and transmitting the plurality of reference signal symbols.

Abstract: Methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to generating a scrambled payload that distinguishes a wireless device using an initialization scrambling sequence. In one exemplary aspect, a method for wireless communication may include generating a scrambled payload, where the scrambled payload is generated using an initialization scrambling sequence that is at least partially based on a preamble index and includes a length of 31 bits. The method also may include transmitting a first message to a communication node during a random access procedure, the first message including the scrambled payload.

Abstract: Disclosed are devices, systems and methods for channel access procedures that include a listen-before-talk (LBT) rule for preventing a mismatch between a sensing beam and a transmission beam. In some implementations, a data communication method includes detecting an idle channel by performing, by a communication node, an energy detection operation based on at least one of a transmission beam or a reception beam, and transmitting, upon detection of the idle channel in at least one of the transmission beam or the reception beam, messages through the transmission beam corresponding to the idle channel.

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: Reducing control signaling is an effective technique for increasing resource efficiency when supporting a massive number of connections in an Internet of Things framework. In the presence of sporadic and small data packets, the use of control signaling must be optimized to not overwhelm network resources. In some embodiments, a bit map in a control signaling packet may indicate if certain information elements that correspond to configuration parameters are present or absent. When they are absent, predetermined values for the corresponding configuration parameters may be used, whereas when they are present, predefined values from a set of predefined values may be used. In other embodiments, the predetermined values may be periodically updated.
