Abstract: This disclosure relates to techniques for providing control signaling for robust uplink data transmissions in a wireless communication system. A wireless device may be configured to perform an uplink transmission, including performing multiple repetitions of the uplink transmission. The wireless may select a beam for each repetition, and it may be the case that different repetitions are transmitted using different beams.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving PDSCH and PDCCH channels. The UE may use the configuration parameters to receive PDSCH and PCCCH that are coverage enhanced using time repetitions and frequency hopping. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.

Abstract: Interference measurement may include decoding a channel state information (CSI) reporting configuration received from a base station. The CSI reporting configuration may be associated with a set of resources for interference measurement. The first UE may be in communication with at least a first transmission and reception point (TRP) of a plurality of TRPs and at least a second TRP of the plurality of TRPs may also be in communication with a second UE that creates cross-link interference for the first UE. At the first UE, a cross-link interference measurement associated with the second UE may be performed using the CSI reporting configuration.

Abstract: Systems, methods, and circuitries are provided for supporting blind retransmission. In one example, a method includes processing control information that indicates resources for communication of a physical downlink shared channel or a physical uplink shared channel (PDSCH/PUSCH) transmission and timing information for a retransmission of the PDSCH/PUSCH. The method includes configuring operation to: receive the PDSCH/PUSCH transmission based on the resources; and determine that a subsequent PDSCH/PUSCH received at a subsequent time corresponds to the retransmission of the PDSCH/PUSCH when the subsequent time coincides with the indicated timing information for the retransmission and, in response combine the PDSCH/PUSCH with the retransmission in a HARQ buffer for decoding purposes.

Abstract: Precoders are provided for multi-panel uplink (UL) transmission. A codebook may support asymmetric multi-panel UL transmission or super UL transmission where new radio (NR) and long-term evolution (LTE) transmissions may be provided through different antenna panels of a user equipment (UE). Sounding reference signal (SRS) enhancement provides support for multi-panel transmission. The UE transmits an indication of a UE capability based on an antenna structure comprising multiple antenna panels of the UE. Further, the UE determines, at the UE, one or more precoders to use for UL transmissions based at least in part on the UE capability, wherein the one or more precoders include a polarization co-phasing factor, an antenna panel co-phasing factor, and a combining weight for antennas for a same polarization. Additionally, the UE transmits, from the multiple antenna panels, the UL transmissions using the one or more precoders.

Abstract: A user equipment (UE) may establish a connection with a network for transmission of a plurality of data bursts further comprising a plurality of data segments. The UE may transmit, to the network, a first data segment corresponding to a first quality of service flow identifier (QFI) associated with a first quality of service (QoS) flow and a second data segment corresponding to a second QFI associated with a second QoS flow. The UE may be configured to map one or more data segments to one or more QFIs based on at least one of a slice type, a frame type, a modulo operation, and a sequence number. The plurality of data bursts may be transmitted according to at least one of one or more configured grants (CGs), one or more dynamic grants (DGs), and one or more instances of the one or more CGs or one or more DGs.

Abstract: A reduced capacity (redcap) device may perform initial uplink communications, including transmitting a redcap physical uplink control channel (R-PUCCH), over an initial uplink bandwidth part (BWP) shared with a second device, the initial uplink BWP having a bandwidth (BW) larger than a maximum BW supported by the redcap device and smaller than or equal to a maximum BW supported by the second device. Frequency hopping operation for the redcap device may be supported for the R-PUCCH transmission through frequency division multiplexing and/or time division multiplexing settings for the resources used for the R-PUCCH transmission, and for PUCCH transmission by the second device. Restrictions may be implemented to create a gap for redcap devices to perform RF retuning between a physical RACH transmission and a subsequent physical control channel (e.g. PDCCH) monitoring for random access reception when the frequency gap is larger than the maximum BW supported by the redcap device.

Abstract: Methods and devices for a UE to multiplex uplink control information (UCI). The UE establishes a connection with a base station. The UE determines whether to multiplex first UCI by first identifying whether intra-priority timing overlap exists between the timing resources of the first UCI and a PUSCH with the same priority. Subsequently, the UE identifies whether inter-priority timing overlap exists between the timing resources of the first UCI and a second PUCCH with a different priority from the first PUCCH. Finally, the UE identifies whether the timing resources of the first UCI overlap with a second PUSCH with a different priority than the first PUCCH. The UE multiplexes the first UCI based on the determination whether to multiplex the first UCI, and transmits the multiplexed first UCI to the base station.
