  • Patent number: 12250708
    Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives, from a network entity, after transmitting at least a first repetition of a physical uplink control channel (PUCCH) transmission according to a first repetition factor, a dynamic indication of a second repetition factor to apply for transmitting the same PUCCH transmission. The UE determines an application time of the second repetition factor based on at least a timing of a last complete or partial transmission instance of the PUCCH transmission. The UE transmits, to the network entity, one or more additional repetitions of the PUCCH transmission based, at least in part, on the determined application time of the second repetition factor.

  • Publication number: 20250081204
    Abstract: Methods, systems, and devices for wireless communications are described that support overlapping physical downlink control channel (PDCCH) candidate thresholds. In some examples, a user equipment (UE) may determine, for each subcarrier spacing (SCS) configuration of a set of SCS configurations, a threshold number of overlapping PDCCH candidates within a time interval. The UE may receive, from a base station, signaling indicating one or more PDCCH monitoring configurations. In some examples, the UE may monitor the PDCCH for control information according to the one or more PDCCH monitoring configurations and a number of overlapping PDCCH candidates, where the number of overlapping PDCCH candidates may satisfy (e.g., be less than or equal to) the threshold number of overlapping PDCCH candidates.

  • Publication number: 20250080271
    Abstract: A new radio (NR) bit prioritization procedure that may be executed by a UE and a base station is disclosed, resulting in transmission and reception of modulation symbols having prioritized bits. For example, a transmitter may encode a code block using low-density parity-check code to generate a stream of encoded bits. The transmitter may arrange the encoded bits in one or more modulation symbols according to a relative priority of the encoded bits. The highest priority bits may be located in the most significant bits of the modulation symbol, and therefore be less likely to experience errors. A receiver may receive the modulation symbols and reorder the encoded bits according to the coding scheme based on the relative priority prior to decoding the encoded bits. The prioritization of the bits within the modulation symbols may provide improved block error rates over sequential mapping of encoded bits to symbols.

  • Patent number: 12213128
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a codebook type for transmitting hybrid automatic repeat request (HARQ) feedback by the UE to a second device (e.g., a network device, a satellite, or a base station). The indication of the codebook type may indicate a HARQ feedback transmission configuration, such as a static HARQ feedback transmission configuration. The HARQ transmission configuration may be associated with a one bit or two bit HARQ codebook. The UE may receive a scheduled downlink shared channel transmission, and attempt to decode the received downlink shared channel transmission. The UE may transmit (or refrain from transmitting) the HARQ feedback based on the decoding of the scheduled downlink shared channel transmission and in accordance with the feedback mode.

  • Patent number: 12177794
    Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

  • Publication number: 20240422774
    Abstract: Aspects presented herein may enable a base station to perform demodulation reference signal (DMRS)-based channel sounding for a channel between the base station and a UE, such that the base station may configure a more suitable precoding for coherent UL multiple input multiple output (MIMO) transmission(s) of the UE without increasing communication overhead significantly or at all. In one aspect, a base station performs channel sounding for a channel based on a set of physical uplink shared channel (PUSCH) DMRS received from a UE via the channel. The base station selects a precoding to be used by the UE for a subsequent PUSCH transmission via the channel based on the channel sounding. The base station transmits, for the UE via a physical downlink control channel (PDCCH), a transmit precoder matrix indicator (TPMI) indicating the selected precoding, where the PDCCH schedules the subsequent PUSCH transmission for the UE.

  • Publication number: 20240414713
    Abstract: Methods, systems, and devices for wireless communications are described. Some examples of the described techniques provide for time-division multiplexing (TDM) modem envelope enhancements. A user equipment (UE) may receive, from a network entity, a message scheduling a transport block or multiple transport blocks in a downlink slot that immediately precedes one or more non-downlink slots (e.g., uplink (U), special(S), or flexible (F) slots) in a TDD slot configuration. The UE may receive the transport block or the multiple transport blocks in the downlink slot, and may process at least a portion of the transport block or the multiple transport blocks during one or more time intervals that occur after the downlink slot. The transport block may satisfy a per-slot transport block size threshold that is associated with a hybrid automatic repeat request (HARQ) processing timeline.
