A base station for wireless communication is provided. The base station including communication circuitry configured to, during transmission time slots, transmit downlink data for reception by terminals, and configured to, during reception time slots, receive uplink data transmitted by the terminals. Downlink scheduling circuitry determines, for each transmission time slot, downlink data allocations, each identifying a terminal to which downlink data is to be transmitted, and wireless communication resources to be used by the wireless communication circuitry to transmit the downlink data to the identified terminal. Uplink scheduling circuitry determines a candidate list of uplink data allocations identifying, for reception time slots, terminals to be allocated to transmit uplink data within the reception time slots and, for each identified terminal, the wireless communication resources to be used. Control information generation circuitry generates downlink information identifying downlink data allocations, and uplink information identifying uplink data allocations selected from the candidate list.

A wireless device may receive a DCI comprising scheduling information for a second uplink transmission via a second carrier. A second timing of the second uplink transmission may be after a first timing of a first uplink transmission via a first carrier. The second uplink transmission may result in an uplink TX switching from the first carrier to the second carrier. Based on the DCI, the wireless device may determine whether a location of a switching period, associated with the uplink TX switching, is on the first carrier or on the second carrier. An uplink transmission may be omitted during the switching period.

Methods and apparatuses for sidelink (SL) positioning within network coverage in a wireless communication system. A method of operating a user equipment (UE) includes receiving, via a downlink (DL) interface, configuration information for a sidelink (SL) positioning reference signal (PRS) and determining, based on the configuration information, resources for the SL PRS on a SL interface. The method further includes transmitting, via the SL interface, an indication of the resources for the SL PRS and transmitting the SL PRS on the indicated resources.

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.

A method, apparatus, and a computer-readable storage medium are provided for improved transport block size (TBS) indication and channel quality indicator (CQI) reporting for lower target block error ratios (BLERs). In an example implementation, the method may include a user equipment configuring a plurality of transport block sizes, activating one or more transport block sizes of the plurality of transport block sizes, and determining a first transport block size from an indication received from a network node when more than one transport block sizes of the one or more transport block sizes are activated. The method may further include determining, a second transport block size, the second transport block size determined based at least on the one or more transport block sizes that are activated and the first transport block size, and receiving a downlink transmission from the network node with the second transport block size. In an additional example implementation, the method may include a user equipment determining a channel quality indicator based at least on a physical downlink shared channel received from a network node and transmitting the channel quality indicator to the network node.
