Some embodiments include an apparatus, method, and computer program product for facilitating frequency hopping for physical uplink shared channel (PUSCH) communications in 5G wireless communication systems. When inter-slot and/or inter-repetition frequency hopping is used, user equipment (UE) may transmit a first portion of symbols in a first slot using a first transmission frequency indicated by a frequency domain resource allocation. The UE may transmit a second portion of symbols in a second slot using a second offset frequency. When intra-repetition frequency hopping is used and the symbols are segmented, the UE may disable the intra-repetition frequency hopping and transmit the segmented portion of symbols using a particular transmission frequency indicated by the frequency domain resource allocation. When intra-repetition frequency hopping is used and the symbols are non-segmented, the UE may apply frequency hopping to divide a portion of symbols for transmission within a repetition.

Frequency hopping for physical uplink shared channel (PUSCH) communications

Apparatuses, systems, and methods for cancellation and/or replacement of PUSCHs. A user equipment device (UE) may configure a first PUSCH and a second PUSCH, where the first PUSCH may correspond to a configured grant and where the second PUSCH may correspond to a configured grant or scheduled by a PDCCH on a serving cell. The UE may determine that at least one transmission occasion associated with the first PUSCH overlaps in time with at least one transmission occasion associated with the second PUSCH. The UE may drop transmissions scheduled for the second PUSCH, e.g., based on determining that a priority of the first PUSCH is higher than a priority of the second PUSCH, e.g., starting with a first symbol of a repetition of the second PUSCH which overlaps in time with one or more repetitions of the first PUSCH.

Cancellation and replacement of PUSCH

Apparatuses, systems, and methods to enhance system performance (e.g., UL throughput) without impinging on (e.g., tightening) processing timeline for UL-SCH data and/or CSI reporting. A base station may request for a UE to send a CSI report(s) during PDCCH monitoring. The base station may also request the UE to send UL-SCH data. At a first transmit opportunity, the UE may transmit first PUSCH (including UL-SCH data that may be multiplexed onto the first PUSCH). Additionally, at a second (later) transmit opportunity, the UE may transmit second PUSCH (including the CSI report(s) that may be multiplexed onto the second PUSCH). The second transmit opportunity may be identified as a transmit opportunity starting at least a specified number of symbols after a first symbol of the first repetition. The specified number of symbols may be dependent upon at least one of UE uplink processing time capabilities or SCS.

UCI multiplexing enhancements

Embodiments described herein include methods, systems, and apparatuses for allowing a user equipment (UE) that supports dynamic spectrum sharing (DSS) with uplink (UL)-shift to access a cell and barring UEs that do not support DSS with UL-shift. Embodiments may use a cell barring field in a master information block and additional filters to indicate a barring state for a network node.

Methods, systems, and apparatuses for handling dynamic spectrum sharing with uplink subcarrier shift

Indicating repetitions at a UE in an NTN includes decoding a communication indicating a timing relationship value associated with a distance between a serving satellite and a farthest UE in the NTN. A PRACH communication is encoded for transmission. The PRACH communication includes an indication of a number of PRACH repetitions determined based on the timing relationship value. A RAR including an uplink (UL) grant corresponding to the UE and an indication of a number of RAR repetitions is decoded. The number of RAR repetitions is determined based on the timing relationship value. A PUSCH communication including an indication of a number of PUSCH repetitions is encoded. The number of PUSCH repetitions is determined based on the timing relationship value. A content resolution communication including an indication of a number of content resolution repetitions is decoded. The number of content resolution repetitions is determined based on the timing relationship value.

Coverage enhancements in NTN

Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.

Systems and methods for overriding grants for CSI-feedback

Performing UCI multiplexing includes generating PUCCH resources Z at an L1 HP procedure and an L1 LP procedure. The L1 HP procedure and the L1 LP procedure results in a plurality of HP PUCCHs and LP PUCCHs, respectively. A modified procedure for Set Q to resources Z is performed with the plurality of HP PUCCHs and LP PUCCHs as inputs. The plurality of HP PUCCHs according to starting symbols is scanned to identify an earliest starting HP PUCCH. A PUCCH from the plurality of LP PUCCHs or HP PUCCHS that overlaps with the earliest starting HP PUCCH is collected. Inter-L1 priority multiplexing is performed on the earliest starting HP PUCCH and the collected PUCCH, which may result in a new HP PUCCH. The new HP PUCCH is inserted into the Set Q. The modified procedure is repeated until there is no overlap among the HP PUCCHs and the LP PUCCHs.

UCI multiplexing procedure for multiple overlapping channels at different physical layer priorities

A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a physical shared channel based on a number of resource blocks determined by one or more formulas for a transport block size (TBS). In response to determining a result of the one or more formulas based on one or more received parameters a configured action for the physical shared channel can be determined based on the number of resource elements (REs). A radio frequency (RF) interface, is configured to provide, to RF circuitry, data for transmitting a new radio (NR) communication based on the configured action.

Transport block size determination for physical shared channel

A method and apparatus for operating a satellite system including different satellites that may belong to different types of satellite constellations. In some implementations, the satellite system may include a LEO satellite constellation and one or more non-LEO satellite constellations that can be used to increase the forward link capacity of the LEO satellite constellation, for example, by allowing an LEO satellite to offload at least some of its forward link traffic to one of the non-LEO satellites. The user terminals can dynamically switch forward link communications between a LEO satellite and a non-LEO satellite while maintaining a return link connection with the LEO satellite.

Method and apparatus for multiplexing hybrid satellite constellations

Various aspects of the disclosure relate to allocating control signaling resources for multiple carrier scenarios. In an example implementation, N-to-1 mapping is used between forward link control signaling resource allocation indices (e.g., control channel elements) and return link control signaling resources (e.g., for ACK/NACK signaling) indices in each return link component carrier. A collision between forward link control signaling assignments for different user terminals (UTs) may occur when UT-specific search spaces overlap each other. Such a collision may be avoided, for example, by scheduling different UTs on different return link component carriers, scheduling return link grants instead of forward link grants, or scheduling a different forward link control signaling candidate that is associated with a different forward link control signaling resource allocation index.

Feedback resource allocation for multiple carriers

Managing handover procedures of two or more modems from a serving base station to a target base station includes receiving at least one message indicative of at least one measurement report of radio conditions from at least one modem of the two or more modems; determining, based on the at least one message, whether to handover the two or more modems from the serving base station to the target base station; and upon determining to handover the two or more modems from the serving base station to the target base station, indicating to each of the two or more modems to send to the serving base station a measurement report configured to trigger a respective handover procedure from the serving base station to the target base station.

Handover management in air-to-ground wireless communication

Methods, systems, and devices are described for implementing timing advances in which a propagation delay may exceed a time period of a portion of a radio frame. In some examples, a transmitter may identify a timing advance indicating a time to initiate wireless uplink transmission of a subframe. Such a timing advance may compensate for a propagation delay between the transmitter and a receiver of the wireless uplink transmission. The timing advance may be applied as an integer component and a fractional component in relation to a duration of the subframe, to adjust the time to initiate the wireless uplink transmission of the subframe. The integer component may be used to adjust one or more subframe characteristics, and the fractional component that may be used to adjust the time to initiate the wireless uplink transmission of the subframe.

Timing advance techniques for large cells

Methods, systems, and devices are described for transmitting across a broad azimuth using an antenna array. In one example, a method is described that includes forming two subarrays from an antenna array. Beamforming weights are selected for each subarray to cause the radiation patterns to be complementary over a range of the azimuth of a cell. The beamforming weights may be selected according to a recursive relation based on the number of antenna elements in each subarray. Information may be encoded, scrambled, and mapped to modulation symbols. A Space Frequency Block Code (SFBC) such as an Alamouti Code may then be used to form two signals to be transmitted over the two subarrays.
