Abstract: Methods, apparatus, systems, architectures and interfaces for encoding/decoding a QD-DTS-PrCC are provided. The decoding method includes determining a number kTS of input bits included in a transmission of a data stream and a first bit of the input bits included in the transmission in the data stream; determining a number of Encoded Bit Blocks (EBBs), each of the EBBs including any number of data blocks that are previously transmitted Transmit Segments (TS) of the data stream, each of the data blocks having a bit length of kTS bits; selecting that number of EBBs for encoding a QD-DTS-PrCC component codeword (QDCC) of the transmission according to a DTS indexing method for indexing a plurality of EBBs; generating the QDCC including a TS, Virtual Segments (VSs), and rc parity bits, a dimensionality of the QD-DTS-PrCC being at least 2; and extracting the calculated TS of the QDCC to an output EBB.

Abstract: Maintaining time alignment with multiple carriers is contemplated. A group of uplink carriers (UL CC sets) that operate with a single Timing Advance (TA) may be determined, and a TA value may be applied to a specific UL CC set. A wireless transmit/receive unit's (WTRU) capability of using multiple TAs may define a group index of a few bits for each UL CC set. A TA Command received in a Random Access Response message may be used to apply the TA value to each UL carrier of the UL CC set. The WTRU may determine which UL CC set the TA value applies to based on which DL carrier the command was transmitted from. The WTRU may determine which UL CC set the TA value applies to based on the Group Index being explicitly provided in the command. The WTRU may release multi-CC configurations upon Time Alignment Timer (TAT) expiry.

Abstract: A wireless transmit/receive unit (WTRU) may receive one or more physical downlink shared channel (PDSCH) transmissions and each PDSCH transmission may be associated with downlink control information (DCI) and a group of PDSCH transmissions. Further, the WTRU may determine a first group or a second group based on an indication received in DCI associated with at least one of the PDSCH transmissions. Then, the WTRU may generate hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for data received in one or more PDSCH transmissions associated with the determined group. Moreover, the WTRU may transmit the HARQ-ACK feedback. In an example, the DCI which includes the indication may schedule a plurality of PDSCH transmissions included in the determined group. In another example, the DCI which includes the indication may further include a first codepoint mapped to the first group or a second codepoint mapped to the second group.

Abstract: Methods and apparatus for multi-link (ML) steering and control in wireless local area network (WLAN) are disclosed. A station (STA) multi-link device (MLD) may communicate over a plurality of links. The STA MLD may receive, from an access point (AP) MLD, on a first link of the plurality of links, a first frame comprising a ML element, where the ML element includes pausing information indicating a period of time during which the STA MLD will pause transmission and reception on the first link. The STA MLD may send, to the AP MLD, on a second link of the plurality of links and during the indicated period of time, uplink (UL) traffic, wherein the first link and the second link are multi-directional links. The STA MLD may be non-simultaneous transmit and receive (non-STR), and the AP MLD may be capable of STR.

Abstract: Systems methods and devices for transmitting a transport block (TB) over multiple slots. A first grant associated with a hybrid automatic repeat request (HARQ) process in a first set of slots is received. A first subset of the first set of slots is determined to be available, and a second subset of the first set of slots is determined to be unavailable, for uplink transmission. The TB is segmented into a first segment and a second segment in response to the determination. The first segment is transmitted in the first subset of the first set of slots. A second grant associated with the HARQ process is received to transmit the TB in a second set of slots. The second segment of the TB is transmitted in the second set of slots.
