Abstract: A system and method for providing early indication by a reduced capability New Radio (NR) User Equipment (UE). In some embodiments the reduced capability UE informs the network, by its use of a combination of preamble, Random Access Channel Occasion (RO), and initial bandwidth part (BWP), that it is a reduced capability UE. In some embodiments, the reduced capability UE transmits payload data in a Message A message. In some embodiments, the reduced capability UE receives, from the network, a set of candidate uplink resources, and transmits a Message 3 message within a subset of the set of candidate uplink resources.

Abstract: A method for performing PDCCH monitoring of component carriers (CCs) in a carrier aggregation scheme that aggregates a first CC and a second CC. In some embodiments, the method includes: calculating a first monitoring occasion start time for a monitoring occasion of the first CC, wherein the first monitoring occasion start time is expressed as a first symbol-index value; calculating a second monitoring occasion start time for a monitoring occasion of the second CC, wherein the second monitoring occasion start time is expressed as a second symbol-index value; and generating a schedule for the monitoring occasion of the first CC and the monitoring occasion of the second CC based on an ascending order of the first monitoring occasion start time and the second monitoring occasion start time.

Abstract: A method for monitoring capability reporting. In some embodiments, the method includes: receiving, by a network, from a user equipment (UE), a physical downlink control channel (PDCCH) monitoring capability, the PDCCH monitoring capability including: a span pattern requirement specifying one or more restrictions on lengths and separations, and a minimum time separation requirement, the minimum time separation requirement specifying a minimum time separation between downlink control informations (DCIs). The method may further include generating, by the network, in response to the PDCCH monitoring capability, a first monitoring occasion (MO) pattern.

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.

Abstract: An apparatus and a method. The apparatus includes a receiver to receive a polar codeword of length mj; a processor configured to determine a decoding node tree structure with mj leaf nodes for the received codeword, and receive i indicating a level at which parallelism of order m is applied to the decoding node tree structure, wherein i indicates levels of the decoding node tree structure, and wherein the mj leaf nodes are at level j; and m successive cancellation list decoders (SCLDs) applied to each child node of each node in the decoding node tree structure at level i−1, wherein each of the m SCLDs executes in parallel to determine log likelihood ratios (LLRs) for a codeword of length mj-i, and wherein each of the m SCLDs uses LLRs of an associated parent node without using a hard decision or a soft reliability estimate of any other node of the other m SCLDs.
