  • Publication number: 20240107439
    Abstract: A system is configured for reconfiguration of a Synchronization Signal Block (SSB) pattern. The system is configured for obtaining data including a configuration for a Synchronization Signal Block (SSB) transmission carrying a physical broadcast channel (PBCH), the configuration specifying, for an SSB of the configuration, resource elements (REs) allocated for transmitting a primary synchronization signal (PSS) to a user equipment (UE) and REs allocated for transmitting a secondary synchronization signal (SSS) to the UE. The system is configured for selecting a set of REs that are unused in the configuration for the SSB transmission, specifying a filling sequence for extending a synchronization signal or an SSB to the set of REs that are unused in the configuration of the SSB transmission, generating data including an enhanced configuration for the SSB transmission that includes the extended synchronization signal or the extended SSBs, and transmitting the SSB transmission using the enhanced configuration.

  • Patent number: 11936588
    Abstract: 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.

  • Publication number: 20240049223
    Abstract: 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.

    Abstract: A user equipment (UE) is configured to receive, from a cell of a network, a system information block (SIB), determine values for scheduling information for the SIB without decoding a Physical Downlink Control Channel (PDCCH) corresponding to the SIB and decode the SIB using the scheduling information. A UE is also configured to receive, from a cell of a network, a message to be decoded, receive, from a source different from the cell, additional information related to a portion of the message, determine the portion of the message using the additional information and decode the message based at least in part on the determined portion of the message.

  • Publication number: 20240031009
    Abstract: Mechanisms are provided for a user equipment (UE) to determine a transmission frequency or a time advance for an uplink transmission from the UE to a base station in a non-terrestrial wireless network (NTN) without global navigation satellite systems (GNSS) information available to the UE. A communication connection between the UE and a base station can be established. The UE can determine that GNSS information is not available, and report to the base station that the GNSS information is not available. The UE can receive, from the base station, an indication of one or more parameters for an uplink transmission from the UE to synchronize the uplink transmission. The UE can determine, based on a current transmission frequency and the received indication of the one or more parameters, a next transmission frequency and transmit the uplink transmission at the determined next transmission frequency.

  • Patent number: 11881942
    Abstract: 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.

  • Publication number: 20230068475
    Abstract: 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.

  • Publication number: 20220417960
    Abstract: 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.
