Abstract: A method and a user equipment (UE) are provided for monitoring physical downlink control channel (PDCCH) candidates by a UE. A reference control resource set (CORESET) having a plurality of transmission configuration indicator (TCI) states is identified. The PDCCH candidates in the reference CORESET and in one or more CORESETs that overlap the reference CORESET in a time domain, are monitored. Each of the one or more CORESETs has a set of one or more TCI states that is either identical to, or a subset of, the plurality of TCI states of the reference CORESET. The monitored PDCCH candidates are received in accordance with a single frequency network (SFN) transmission scheme.

Abstract: A method and a user equipment (UE) are provided for explicitly linking repeated physical downlink control channels (PDCCHs). The UE receives the repeated PDCCHs from a network. Each of the repeated PDCCHs include downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE. The UE links the repeated PDCCHs having common PDCCH candidate numbers across search space (SS) sets of a control resource set (CORESET). The repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission and reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.

Abstract: A system and a method are disclosed for accessing a wireless medium for a NR-U deployed at 60 GHz. A directional CCA sensing is performed on a set of multiple beams in the medium in which each beam is oriented in a different direction. It is determined whether at least one beam of is busy and, if so, a back-off timer is initialized. The back-off timer is decreased by a predetermined amount based on a determination that all beams of the set of multiple beams are idle. The back-off timer is repeatedly decreased the predetermined amount based on a determination that all beams of the set of multiple beams are idle until the back-off timer equals a predetermined amount. Data is transmitted at least one beam of the set of multiple beams based on the back-off timer equaling the predetermined amount.

Abstract: A system and a method are disclosed for beam refinement to enable inactive mode transmission in frequency range 2 for 3GPP RedCap devices. A RedCap device receives system information in a SIB1 from a wireless network in which the SIB1 includes information relating to an indication of resources used to transmit a SIB-x. The device receives the SIB-x, which includes an indication of at least one resource, at least one configuration for a Downlink-Reference Signal (DL-RS) transmission, and information relating to a measurement report relating to the beam-refinement measurement that is to be performed by a device. The device receives the DL-RS transmission from the wireless communication network, performs the beam-refinement measurement, and sends a measurement report to the wireless network. Subsequent to sending the measurement report, the device sends an enhanced transmission to the wireless network based on the measurement report.

Abstract: A method may include multiplexing control information on a physical channel in a communication system, wherein the control information comprises a repeat request acknowledgment portion, and allocating an amount of resources of the physical channel for the repeat request acknowledgment portion based on an amount of a type of acknowledgment included in the acknowledgment portion. The type of acknowledgment may include an acknowledgment for dynamically granted traffic. The amount of resources may include a reserved amount of resources based on the amount of acknowledgment for dynamically granted traffic being less than a threshold. A method may include multiplexing control information on a physical channel in a communication system, wherein the control information may include a repeat request acknowledgment portion, and allocating an amount of resources of the physical channel for the repeat request acknowledgment portion based on a threshold, wherein the threshold is variable.

Abstract: A symmetric interleaver for a Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN) encoder and a circular padding mode are disclosed. The interleaver interleaves elements of an input block to form an output block in which an output neighborhood of elements for each element of the output block is symmetric to an input neighborhood of elements for each element of the input block. A position of an element of the input block is interleaved based on an index i of the position times a parameter δ modulo K in which the parameter δ is relatively prime with K. A test loss function may be used to train the encoder that includes a Binary Cross Entropy (BCE) loss function plus a function that minimizes a number of codeword pairs based on a Euclidean distance. The RNN encoder may be implemented as part of a Turbo Autoencoder (TurboAE) encoder.
