Abstract: The present disclosure describes methods, system, and devices for configuring hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback for physical downlink shared channel (PDSCH) transmission. The method includes receiving, by a user equipment (UE), a radio resource control (RRC) parameter to configure a one-shot HARQ-ACK feedback mode; and receiving, by the UE, a first downlink control information (DCI) comprising a first K, the first DCI corresponding to a first PDSCH. The method includes receiving, by the UE, a second DCI comprising a second K with an applicable value and an one-shot request field with a positive value, the second DCI corresponding to a second PDSCH; and transmitting, by the UE, a one-shot HARQ-ACK feedback according to a preset rule.

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.

Abstract: A wireless communication method includes a network node that transmits to one or more communication nodes a set of parameters for selection of a multiple access transmission scheme from a plurality of multiple access transmission schemes, such as an orthogonal multiple access (OMA) scheme and a non-orthogonal multiple access (NOMA) scheme. The network node receives data transmitted by a communication node using the multiple access transmission scheme selected by the communication node. The network node can also transmit one or more sets of parameters for one or more transmission configuration groups or a set of parameters for re-transmission, where the transmission configurations group(s) and the parameters for re-transmission define a multiple access transmission scheme to be selected from a plurality of multiple access transmission schemes.

Abstract: Presented are systems and methods for calculating and configuring a random access channel (RACH). A wireless communication device may determine whether a gap is to be present between a pair of adjacent random access channel (RACH) occasions (ROs), for a subcarrier spacing (SCS) of a physical RACH (PRACH) slot that is higher than 120 kiloHertz (KHz) or 60 KHz. The wireless communication device may determine a length of the gap, if the gap is to be present.

Abstract: This patent document describes, among other things techniques for determining when to switch between a channel access procedure that includes a listen before talk (LBT) process and a channel access procedure that does not include a LBT process. In one aspect, a method of wireless communication is disclosed. The method includes receiving, by a first network node from a second network node, a message specifying a first channel access procedure to be used by the first network node after being powered up. The method further includes selecting, by the first network node, a second channel access procedure to be used after the first channel access procedure after satisfying a condition, wherein if the condition is not satisfied the first network node continues to use the first channel access procedure.
