  • 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.

  • Publication number: 20240380514
    Abstract: A method for wireless communication at a transmitting wireless device and related apparatus are provided. In the method, the device determines, based on the first parameter associated with a Forward Error Correction (FEC) process and a second parameter associated with a probabilistic shaping process, the transport block (TB) size for a TB associated with a signal to be transmitted, and performs the probabilistic shaping process on a first set of data bits of the signal on the TB to obtain a second set of transmit bits. The TB cyclic redundancy check (CRC) is inserted into the TB before or after the probabilistic shaping process, and the probabilistic shaping process is applied on the TB level across multiple code blocks (CBs) associated with the TB or on the CB level individually inside each CB of the multiple CBs. The device further transmits the signal using the second set of transmit bits.

  • Publication number: 20240340734
    Abstract: Various aspects of the present disclosure generally relate to wireless communication and more particularly to hybrid measurements and reporting for Layer 1 (L1)/Layer 2 (L2) triggered mobility (LTM). Some aspects more specifically relate to a UE performing filtered measurements of one or more LTM candidate cells. In some aspects, the hybrid measurements and reporting may be associated with measurements using Layer 3 type measurements and reporting using L1 type reports for LTM. In some aspects, one or more cells, from the one or more LTM candidate cells, may be selected (for example, by the UE or by a network node) for L1 measurement or reporting associated with the filtered measurement values. In some aspects, the UE may transmit an L1 measurement report indicating L1 measurement values of the one or more cells. A network node may perform one or more operations in response to the L1 measurement values.

  • Publication number: 20240340898
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) receives physical downlink control channels from transmission and reception points (TRPs). The physical downlink control channels may be jointly decoded to facilitate joint demodulation of physical shared channels. The UE receives a first downlink control information (DCI) over a first downlink control channel associated with a first TRP and a second DCI over a second downlink control channel associated with a second TRP. The first downlink control channel overlaps in time with the second downlink control channel. The first DCI schedules a first downlink shared channel associated with the first TRP and the second DCI schedules a second downlink shared channel associated with the second TRP. The UE receives the first downlink shared channel and the second downlink shared channel that overlap in time. The UE performs joint demodulation of the first and second downlink shared channels.
