Abstract: Methods, systems and devices for wireless communication are described. One example method includes determining, using resources in a wireless network, a schedule of transmissions between the wireless network and one or more user devices, and controlling the transmissions according to the schedule. The resources are distributed between a central unit (CU) and a distributed unit (DU) according to a resource partitioning scheme. The DU is configured to handle a first set of protocol layers of a communication protocol stack implemented in the wireless network according to a layer partitioning scheme and the CU is configured to handle a second set of protocol layers of the communication protocol stack according to the layer partitioning scheme. The first set of protocol layers excludes an upper medium access control (MAC) layer. The second set of protocol layers excludes a physical layer.

Abstract: A base station transmits one or more configuration parameters indicating a single frequency network (SFN) scheme. The base station transmits, via control resource sets (coresets) configured for physical downlink control channel (PDCCH) repetition, repetitions of downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH). The base station transmits the PDSCH based on transmission configuration indicator (TCI) states of the coresets. The PDSCH transmission is in response to: the one or more configuration parameters indicating the SFN scheme; the DCI not comprising a TCI field; and a time offset between the DCI and the PDSCH being equal to or greater than a threshold.

Abstract: Message faults are inevitable in the high-throughput environment of 5G and planned 6G. Retransmissions are costly in time and resources, while generating extra backgrounds and interference. Therefore, methods are disclosed for recovering a faulted message by identifying and correcting each mis-demodulated message element. The faulted message elements generally have substantially lower modulation quality than the correctly demodulated elements, and can be identified by determining the modulation quality of each received message element. If the number of faulted message elements is small, the receiver may correct them using a grid search tested by an associated error-detection code. If the number of faults exceeds a predetermined threshold, the receiver can request a retransmission, and then assemble a merged copy of the message by selecting the message element with the best modulation quality from each version. Substantial time and resources may be saved, and reliable communication may be restored despite poor reception.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The disclosure relates to an operation of a RedCap UE and a base station in a wireless communication system. More specifically, the disclosure relates to an operation method of a RedCap UE considering a switching gap and an apparatus for performing the same. A method performed by a terminal in a communication system includes receiving, from a base station, information indicating positions of SS/PBCH blocks, identifying the positions of the SS/PBCH blocks based on the information, receiving, from the base station, configuration information on PUSCH repetition, identifying available resources for the PUSCH repetition by determining resources overlapped with the positions of the SS/PBCH blocks and switching intervals for the SS/PBCH blocks as unavailable resources for the PUSCH repetition, and repeatedly transmitting, to the base station, UL data on a PUSCH based on the available resources.

Abstract: A retransmission method includes obtaining, by a transmitter, a to-be-coded bit sequence that comprises K to-be-coded bits, where K is a positive integer. The retransmission method further includes performing polar coding on the to-be-coded bit sequence thereby obtaining a coded first bit sequence, and determining an initial transmission version (RV0). A length of the coded first bit sequence is N0. The retransmission method further includes determining a length (E1) of a retransmission version (RV1), determining the RV1 based on an initial transmission bit rate (R0), and sending the RV1.
