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

Described herein are systems and methods for resource block determination for multicast and broadcast transmissions. According to various embodiments, a unicast physical downlink shared channel (U-PDSCH) transmission and a group common physical downlink shared channel (GC-PDSCH) transmission are received; a resource block (RB) configuration for decoding the U-PDSCH transmission and GC-PDSCH transmission is determined, wherein the RB configuration specifies a mapping of at least one of the U-PDSCH and the GC-PDSCH to one or more RB collections; and the GC-PDSCH within a Common Frequency Resource (CFR) in decoded according to the RB configuration. According to various embodiments, the determined RB configuration includes a specification of size and location for the one or more RB collections which at least one of the U-PDSCH and the GC-PDSCH is mapped to. In various embodiments, RB collection size and location may be determined relative to CRB indexes and/or a CFR.

System and method for resource block determination for mulitcast and broadcast transmissions

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

A system and a method in a wireless communication network are disclosed to reduce a power consumption of a Multicast and Broadcast Services (MBS) device. The device includes an interface to the wireless communication network that receives wireless communications from the wireless communication network, and a controller. The controller controls the interface to receive unicast communications in a bandwidth part (BWP) of the wireless communication network and to receive MBS communications in a common frequency resource (CFR) of the wireless communications. The controller further controls the interface by selectively receiving MBS communications in the CFR to reduce a frequency bandwidth of the interface, or a combination thereof, to reduce a power consumption of the device.

Reducing power consumption for MBS UEs

A system and method for channel access mode selection. In some embodiments, the method includes receiving, by a user equipment (UE), an interference measurement configuration from a network; performing, by the UE, a first interference measurement according to the interference measurement configuration; and implementing a first channel access mode. The implementing of the first channel access mode may include (i) identifying, by the UE, the first channel access mode based on the first interference measurement; or (ii) reporting, by the UE, a result of the first interference measurement, in order for the first channel access mode based on the first interference measurement to be identified.
