A system and method for selecting a number of cyclic redundancy check bits in a communication system. In one embodiment, an apparatus operating in a communication system is configured to receive scheduling information from the communication system, and determine an information block length (K) and/or code rate (R) for a code block including a sequence of data bits from the scheduling information. The apparatus is further configured to determine a number of cyclic redundancy check (CRC) bits as a function of the information block length (K) and/or code rate (R) for the code block.

Cyclic redundancy check selection

A wireless communication device () replicates, at a Radio Link Control (RLC) layer of a protocol stack of the wireless communication device (), an original packet associated to a particular service to provide one or more replicate packets. Each of the one or more replicate packets is a replication of the original packet. For each packet from among a set of packets consisting of the original packet and at least one of the one or more replicate packets, the wireless communication device () generates a transport block that comprises the packet and transmits the transport block to one or more base stations or transmission/reception points, TRPs, via a physical layer of the protocol stack of the wireless communication device ().

Replication in a wireless communication network

Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

Industrial automation with 5G and beyond

A method for repeating a Transport Block (TB) over multiple transmission occasions. The method includes exchanging specific signaling between a wireless device (e.g., a user equipment) and a network node (e.g., a base station) to repeat same or different redundancy versions of the TB in multiple non-overlapping transmission occasions (e.g., mini-slots) corresponding to multiple Transmission Configuration Indication (TCI) states and having different start positions. More specifically, the network node transmits a Time Domain Resource Allocation (TDRA) to indicate the multiple non-overlapping transmission occasions and the wireless device receives the TDRA indicating the multiple non-overlapping transmission occasions. Accordingly, the wireless device can receive repetition of the TB according to the TDRA. By indicating transmission occasions in the TDRA, it is possible to efficiently schedule multiple transmission occasions over the multiple TCI states, thus helping to improve efficiency, reliability, and coverage in a wireless communications network.

Systems and methods for providing feedback are provided. In some embodiments, a method performed by a wireless device includes: determining a set of occasions for candidate PDSCH receptions taking into account the number of sub-slots in an uplink slot; determining a set of occasions for Semi-Persistent Scheduling (SPS) PDSCH releases taking into account the number of sub-slots; the number of sub-slots is used to scale the number of downlink slots within an uplink slot when determining a set of occasions for candidate PDSCH receptions; and the number of sub-slots is used to scale the number of downlink slots within an uplink slot when determining a set of occasions for SPS PDSCH releases. Some embodiments allow for a full support of Type-1 HARQ-ACK codebook for subslot-based HARQ-ACK. Some embodiments are simple to implement into the specification and preserve the existing behavior for the slot-based Type-1 HARQ-ACK codebook determination.

Systems and methods of the present disclosure are directed to a method performed by a wireless communication device. The method includes receiving, from a network node, information that configures the wireless communication device for a Configured Grant (CG) based Physical Uplink Shared Channel (PUSCH) transmission with PUSCH repetitions towards two or more transmissions/reception points (TRPs). The method includes performing the CG based PUSCH transmission with PUSCH repetitions towards the multiple TRPs in accordance with the received information.

Configured grant based PUSCH transmission to multiple TRPs

A method of producing a set of coded bits from a set of information bits for transmission between a first node and a second node in a wireless communications system, the method comprises generating a codeword vector by encoding the set of information bits with a low-density parity-check code, wherein the codeword vector is composed of systematic bits and parity bits. The method comprises performing circular buffer-based rate matching on the generated codeword vector to produce the coded bits for transmission, wherein the circular buffer-based rate matching comprises puncturing a first plurality of systematic bits.

Rate matching methods for LDPC codes

According to some embodiments, a wireless device is operating in communication with two or more serving cells wherein at least one serving cell of the two or more serving cells is configured for release 16 reporting of physical downlink control channel (PDCCH) monitoring capabilities. The wireless device performs a method comprising transmitting a first parameter representing a release 16 PDCCH monitoring capability of the wireless device to a network node and determining a maximum number of PDCCH candidates and a maximum number of non-overlapped control channel elements (CCEs) based on a maximum number of release 16 capable serving cells, which is determined based on the transmitted first parameter.

A User Equipment (UE) () configured for operation in a wireless communication network () ignores a received preemption indicator responsive to determining that the involved data transmission by the UE () will carry Uplink Control Information (UCI) from the UE (), at least when the UCI is of a certain type or priority. For example, the UE () ignores the preemption indicator if the UCI is of the certain type or priority, and otherwise follows the preemption indicator by skipping the uplink data transmission. Correspondingly, a radio network node () configured for operation in the wireless communication network () determines whether an uplink data transmission by a UE () on certain radio resources will include UCI, and the radio network node () transmits or does not transmit a preemption indicator preempting use by the UE () of the certain radio resources for the uplink data transmission, in dependence on the determination.
