  • 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.

  • Patent number: 12113617
    Abstract: The disclosure relates in some aspects to information encoding. Information encoding may involve puncturing bits of a codeword or repeating bits of a codeword. The disclosure relates in some aspects to selecting a puncturing or repetition pattern. In some aspects, a puncture pattern for data encoding is selected based on a criterion that the output and the repetition input of an XOR are not erased. In some aspects, a repetition pattern for data encoding is selected based on a criterion that repetition not be applied for the output and the repetition input of an XOR.

  • Patent number: 12068901
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may perform a pre-distortion of a signal on a resource allocation for the signal and using discrete Fourier transform (DFT)-domain processing. For example, the transmitting device may perform a first frequency-domain (FD) to time-domain (TD) transform, which may be an example of an inverse DFT (IDFT), on a first set of FD symbols to obtain a first set of TD samples. A size of the first FD to TD transform may be based on the resource allocation for the signal. The transmitting device may perform a crest factor reduction (CFR) function on the first set of TD samples to pre-distort the signal in the TD (e.g., in the IDFT domain), which may enable the transmitting device to avoid out-of-band (OOB) emission or otherwise have greater control over where the pre-distortion contributes energy.

  • Publication number: 20240236737
    Abstract: This disclosure provides systems, methods and apparatuses that support channel state information (CSI) reporting techniques for secondary cell (SCell) activation. A user equipment (UE) may receive one or more medium access control-control elements (MAC-CEs) that indicate a secondary cell (SCell) activation command, an aperiodic tracking reference signal (AP-TRS) trigger, and an aperiodic channel state information (AP-CSI) report trigger. The network entity may signal the SCell activation command, the AP-TRS trigger, and the AP-CSI report trigger in the same MAC-CE or in separate MAC-CEs. The UE may receive and measure AP-TRS in accordance with the AP-TRS trigger indicated by the one or more MAC-CEs, and may perform measurements via an aperiodic channel measurement resource (AP-CMR) and an aperiodic interference measurement resource (AP-IMR) in accordance with the AP-CSI report trigger indicated by the one or more MAC-CEs. Accordingly, the UE may transmit an AP-CSI report associated with the measurements.

  • Publication number: 20240236726
    Abstract: A UE may attempt, based on a first mode, to identify a first opportunity within a preconfigured time period for a measurement associated with at least one SCC when the at least one SCC is deactivated at the UE and the measurement associated with the at least one SCC is due based on a scheduling. Based on the first mode, a radio of the UE may not be tuned to the at least one SCC when the at least one SCC is deactivated at the UE and no measurement associated with the at least one SCC is being performed at the UE. The UE may perform, if the first opportunity is identified within the preconfigured time period, the measurement associated with the at least one SCC at the identified first opportunity.

  • Publication number: 20240235798
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. Various aspects relate generally to anchor cell management for a synchronization signal block (SSB)-less secondary cell (SCell). In some aspects, an anchor cell in a different frequency band from an SSB-less SCell may be used for downlink beam management of the SSB-less SCell. A UE may report, to a network node, reference signal received power (RSRP) measurements for a plurality of downlink reference signals transmitted via the anchor cell, and the network node may determine a downlink beam for the SSB-less SCell based at least in part on the RSRP measurements. The UE may receive a configuration of the SSB-less SCell, and the configuration may indicate the anchor cell associated with the SSB-less SCell. The UE may receive an activation indication that activates the SSB-less SCell for the UE.

  • Patent number: 12004176
    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: 20240172257
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. A UE capability for a multiple physical downlink shared channel (PDSCH) scheduling may be signaled from a UE to a network entity. A UE capability signaling may indicate whether the UE supports a multiple PDSCH scheduling being associated with a same time domain resource allocation (TDRA) and/or a same frequency domain resource allocation (FDRA). The network node may schedule the multiple PDSCHs, via a multiple user multiple-input multiple-output (MU-MIMO) PDSCH scheduling or a multiple downlink control information (multi-DCI) multiple transmission reception point (mTRP) PDSCH scheduling, based at least in part on the UE capability signaling. The network entity may guarantee that co-scheduled PDSCHs have the same TDRA and/or the same FDRA, which may be based at least in part on the UE capability signaling.
