A system and a for dynamic uplink transmitter switching may include configuring, by a user equipment (UE), a first uplink (UL) transmission on one or more carriers out of at least three carriers; configuring, by the UE, a second UL transmission on the one or more carriers out of the at least three carriers; and scheduling, by the UE, an interruption time on one or more of the at least three carriers according to a predetermined criteria based on a state of transmit (Tx) chains for the first UL transmission and a state of Tx chains for the second UL transmission.

Systems and methods for dynamic uplink transmitter switching

A method may include sending a contention resolution message for a random access procedure from a user equipment (UE) through a physical uplink channel in a wireless communication network, and sending a repetition of the contention resolution message from the UE through the physical uplink channel. The physical uplink channel may include a physical uplink shared channel (PUSCH). The method may further include selecting a preamble from a first preamble group corresponding to a capability of the UE to send the repetition of the contention resolution message, and sending the preamble from the UE. Selecting the preamble from the first preamble group may include selecting a preamble from a first preamble sub-group corresponding to the capability of the UE to send the repetition of the contention resolution message.

Methods and apparatus for random access with contention resolution message repetition

An apparatus and method are provided for performing a subband operation for cross division duplex (XDD) technology to enhance coverage in wireless communication systems. A method includes identifying, by a user equipment (UE), an uplink (UL) or downlink (DL) subband configuration provided from a gNB to the UE, and determining a priority between a UL transmission and a DL reception based on whether a collision between DL and UL operations occurs in a time domain, wherein the UE is a half-duplex UE which performs the UL transmission at different times than when the UE performs the DL reception.

Subband operation for cross division duplex technology

A system and a method are disclosed relating to a transport block processing chain for a transmitter. A code block determination circuit may be configured to determine a size of a code block that maps across multiple slots of a wireless physical shared channel according to a Transport Block over Multiple Slots (TBoMS) configuration, and a rate matching circuit may be configured to rate match bits of the code block to a number of bits available in a transport block that spans the predetermined number of slots of the wireless physical shared channel. Additionally, an interleaver may be configured to interleave a continuous output of the rate matching circuit on a slot basis so that a code block that crosses a slot boundary between a first slot and a second slot is interleaved within the first slot and the second slot.

Transport block mapping across slots

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.

Methods for dynamic HARQ-ACK codebook with multiple sub-codebooks

A method for PUSCH repetition or PRACH aggregation. In some embodiments, the method includes transmitting, by a User Equipment (UE), in a first slot, a first Physical Uplink Shared Channel (PUSCH) transmission including a set of coded bits selected from a circular buffer of the UE based on a first redundancy version (RV); determining, by the UE, that a second slot is available for an earliest repetition of the first PUSCH transmission, the second slot being later than the slot immediately following the first slot; determining, by the UE, based on the second slot, a second redundancy version; and transmitting, by the UE, in the second slot, a second PUSCH transmission including a set of coded bits selected from the circular buffer of the UE based on the second redundancy version, the second PUSCH transmission being a repetition of the first PUSCH transmission.

PUSCH and PRACH enhancements

Disclosed is a method of transmitting a demodulation reference signal (DMRS) by a user equipment (UE) using carrier aggregation, including transmitting, over a first component carrier (CC), a first transmission using a first power and a second transmission using a third power; and transmitting, over a second CC and simultaneously with the first transmission and the second transmission over the first CC, a first transmission using a second power and a second transmission using a fourth power, wherein a sum transmission power across the first and second CCs is maintained during an entire DMRS bundling duration.

Demodulation reference signal bundling in carrier aggregation

An system and a method are disclosed for sequence-based physical uplink control channels (PUCCHs). A method includes a UE determining an uplink control information (UCI) payload to be transmitted, determining, based on the UCI payload to be transmitted, a grouping of resource sets and sequences, each sequence corresponding to a resource set, selecting one or more resource sets and one or more sequences from among the determined grouping of resource sets and sequences, according to a mapping operation, for transmitting the UCI payload, and transmitting the selected one or more sequences as part of a UCI payload transmission.

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.
