  • Publication number: 20250112599
    Abstract: Systems, methods, apparatuses, and computer program products for network-assisted signaling for uplink digital pre-distortion (DPD). A gNB may use an uplink reference signal (RS) to measure a user equipment's (UE's) power amplifier (PA) nonlinearity, where the UE may transmit its UE-specific RS with maximum transmit (Tx) power at a PA measurement window in the uplink. The gNB may train an artificial intelligence-based model to approximate the pre-distortion function (with PA parameters). The gNB may signal DPD-related information, and the UE may determine (and adjust) its DPD function based on the gNB signalling.

  • Publication number: 20240089706
    Abstract: A user equipment transmits a request to configure a first network to transmit complementary content associated with multicast or broadcast content received at the user equipment from a second network. In some cases, the request is transmitted in response to the user equipment detecting that a quality of a signal received from the second network is below a threshold. In response to receiving the request, the first network is configured to transmit the complementary content. The complementary content is transmitted from the first network concurrently with transmitting the multicast or broadcast content from the second network. The user equipment combines the complementary content received from the first network with the multicast or broadcast content received from the second network.

  • Publication number: 20240056776
    Abstract: This disclosure presents methods and processes to allow a user equipment (UE) to map a hybrid automatic retransmission request-acknowledgement (HARQ-ACK) feedback to one or more HARQ-ACK sub-codebooks for received services. The one or more HARQ-ACK sub-codebooks can be concatenated into one HARQ-ACK codebook and then communicated to a communication node, when those services use a HARQ-ACK feedback that is scheduled for the same time instance. Various methods can be used for the concatenation order depending on the number of multicast and broadcast services (MBS) for which HARQ feedback is to be provided, and depending on whether HARQ-ACK feedback is to be sent for unicast services at the scheduled time instance. The concatenation order can utilize an increasing order or a decreasing order of the concatenation order parameters.
