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: Methods, systems, and devices are disclosed for digital wireless communication, and more specifically, for the use of pilot sequences that improves performance of channel estimation. In one exemplary aspect, a method of wireless communication performed by a communication node is disclosed. The method includes determining, using a first index, a mask sequence from a plurality of pre-determined mask sequences, wherein the plurality of pre-determined mask sequences is determined based on permutations of values 1, −1, i, and −i or permutations of values 1+i, or 1−i, or −1+i, or −1−i; determining a Walsh sequence using a second index, wherein the Wash sequence has a same length as the mask sequence; generating a pilot sequence by combining the mask sequence and the Walsh sequence; and performing a wireless transmission using the pilot sequence.

Abstract: The present invention relates to a method and apparatus for processing a modulation symbol. The processing method comprises: a transmitter obtaining a transmission power ratio αj, wherein in the transmission power ratio αj□{α0, α1, α2}, j is a natural number, and α0, α1 and α2 are all positive numbers; and the transmitter modulating a first group of bit sequences b0(i), b0(i+1) and a second group of bit sequences b1(i), b1(i+1), . . . , b1(i+n) according to the transmission power ratio αj so as to obtain a modulation symbol, wherein i is a natural number, and n□{1, 3, 5}. The present invention solves the problem in the relevant art that an uncertain number of transmission power ratios affects the performance of a system and increases the design complexity of signaling, thereby reducing signaling overheads and improving system stability and demodulation performance.

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: This disclosure relates to wireless communication formats that avoid conflicts in message transmissions. In one implementation, conflicts are avoided by determining that transmitting the uplink message according to a first transmission format will result in a conflict, and responsively determining to transmit the uplink message according to a second transmission format. In another implementation, conflicts are avoided by waiting to transmit a message part until a next time unit of a physical channel that is not conflicted. In another implementation, conflicts are avoided by configuring time units of a second physical channel relative to time units of a first physical channel according to an uplink time unit offset.
