  • Publication number: 20250150316
    Abstract: A computer-readable storage medium stores instructions to configure one or more processors of a Further Reduced Capacity (F-RedCap) UE for operation in a 5G NR network, and to cause the F-RedCap UE to perform operations including decoding a PBCH to obtain a numerology parameter. A maximum resource block (RB) allocation is determined for a bandwidth associated with the numerology parameter. The maximum RB allocation is adjusted based on a reduced bandwidth associated with the F-RedCap UE to obtain an adjusted RB allocation. A maximum data rate is determined based on the numerology parameter and the adjusted RB allocation. Data is encoded for an uplink (UE) transmission to a base station. The UE transmission uses the maximum data rate.

  • Publication number: 20250142566
    Abstract: A UE configured for operating in a 5G NR network may decode signalling that schedules two physical downlink shared channels (PDSCHs) in a same time slot. When the UE is a reduced-bandwidth (RBW) reduced-capacity (RedCap) UE (RBW-RedCap UE), the UE may determine if a total number of allocated PRBs in an OFDM symbol for the two scheduled PDSCHs exceed a predetermined value when the two scheduled PDSCHs either partially or fully overlap in time in non-overlapping PRBs. The UE may also prioritize decoding of one of the two scheduled PDSCHs when the total number of allocated PRBs exceed the predetermined value and when the two scheduled PDSCHs either partially or fully overlap in time in non-overlapping PRBs. If a first of the two scheduled PDSCHs is a unicast PDSCH and a second of the two scheduled PDSCHs is a broadcast PDSCH, the UE may prioritize decoding of the unicast PDSCH.

  • Patent number: 12289732
    Abstract: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.

  • Patent number: 12238029
    Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical downlink control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCII. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

  • Patent number: 12231935
    Abstract: Technology for a user equipment (UE) operable to perform downlink (DL) channel quality measurement reporting is disclosed. The UE can decode a system information block type y bandwidth reduced (SIBy-BR) received from an eNodeB. The SIB1-BR can instruct the UE to include a DL channel quality measurement report in a message 3 (Msg3) transmitted during a random access procedure between the UE and the eNodeB, wherein y is a positive integer greater than or equal to 1. The UE can determine a DL channel quality measurement for a DL channel between the UE and the eNodeB. The UE can encode the Msg3 for delivery over an uplink channel to the eNodeB. The Msg3 can be delivered during the random access procedure and can include the DL channel quality measurement report with the DL channel quality measurement.

  • Publication number: 20250056554
    Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.
