Abstract: The disclosure provides an apparatus and method supporting enhanced transmission schemes of up to 8 transmission port (8 TX) uplink (UL) transmission for sounding reference signals (SRSs). A method performed by a user equipment (UE) includes receiving, from a base station, downlink control information (DCI) including a sounding reference signal (SRS) resource indicator (SRI) field; and transmitting an SRS based on an SRS resource allocated to the UE in the SRI field. The SRI field indicates a transmission rank and one or more precoding weights based on an SRS set including NSRS SRS resources, where 1≤NSRS≤8, and an SRI field bit length that is less than a threshold value determined from a maximum number of layers to be transmitted and the NSRS SRS resources.

Abstract: Various aspects include a method of providing, by a network to a UE device, a transmission grant. The method includes initiating a process to provide the transmission grant for a transmission within a particular time. The method includes verifying that there is no cancellation indication that overlaps the particular time. The method includes providing, based on the verification, the transmission grant to the UE device. The method includes determining whether there is no transmission that overlaps with a cancellation window associated with a monitoring occasion, and based on the determination, skipping the monitoring occasion. Also disclosed a system for providing a transmission grant to the UE device.

Abstract: A system and method for handling acknowledgments in a wireless system. In some embodiments, the method includes, receiving, by a User Equipment (UE), one or more first transmissions; decoding, by the UE, the first transmissions, to generate a first sub-codebook including one or more corresponding Hybrid Automatic Repeat Request Acknowledgement (HARQ ACK) bit strings each having a first length; receiving, by the UE, one or more second transmissions; decoding, by the UE, the second transmissions, to generate a second sub-codebook including one or more corresponding HARQ ACK bit strings each having a second length, greater than the first length; receiving, by the UE, one or more third transmissions; and decoding, by the UE, the third transmissions, to generate a third sub-codebook including one or more corresponding HARQ ACK bit strings each having a third length, greater than the second length.

Abstract: A system and method for random access procedures in a non-terrestrial network. In some embodiments, the method includes calculating, by a user equipment (UE), a timing advance based on location information of the UE and on an ephemeris of a non-terrestrial network node. The method may further include randomly selecting a random value from a plurality of values, and sending, at a transmission time, by the UE, to the non-terrestrial network node, a random access (RA) message, which may include a signature. The transmission time may differ from a nominal transmission time by an amount based on the random value, the nominal transmission time being based on the timing advance, or the signature may differ from a nominal signature by a cyclic shift based on the random value.

Abstract: A system and method for positioning in RRC Idle and Inactive states. In some embodiments, the method includes receiving, by a user equipment (UE), in Idle or Inactive state, a downlink positioning reference signal (PRS); transmitting, by the UE, in Idle or Inactive state, an uplink reference signal; and transmitting, by the UE, in Idle or Inactive state, a PUSCH carrying an estimate of the position of the UE. The uplink reference signal may be a positioning sounding reference signal (SRS), or a Physical Random Access Channel (PRACH) preamble with sequence length greater than 1151.

Abstract: A method and an apparatus are provided for decoding a polar code. A simplified successive cancellation list (SSCL) decoding tree for the polar code is generated. The SSCL decoding tree includes a plurality of nodes. One or more nodes of the plurality of nodes are identified as employing Reed-Muller codes for decoding. Decoding of received log-likelihood ratios (LLRs) is performed using Reed-Muller codes at the one or more nodes. Hard decision values are output from the one or more nodes.
