  • Publication number: 20240171354
    Abstract: A base station may identify an association between a set of physical cell identifiers (PCIs) identifying different transmission reception points (TRPs) and a set of transmission configuration indicator (TCI) states for a user equipment (UE). The base station may transmit a TCI state and PCI association indication to the UE. The UE may receive a downlink transmission using a receive beam associated with a TCI state, and may identify a PCI of the set of PCIs to use to decode the received downlink transmission. In cases where the TCI state used to receive the downlink transmission is associated with multiple PCIs, the UE may select a default PCI from the multiple PCIs, and may decode the received transmission accordingly. In some examples, the UE may receive reference signals from one or more of the serving TRPs and may identify a PCI to use to decode the received reference signals.

  • Publication number: 20240171220
    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support user equipment (UE) cooperation. When a first UE and second UE are in a cooperative configuration, a base station may use the first UE to request and obtain channel information for the second UE. For example, the base station may transmit a request for channel information to the first UE and the first UE may relay the request to the second UE. The second UE may determine the channel information and transmit a report including the channel information to the first UE, where the first UE may relay the report to the base station. In some examples, the report, the request, or both may be exchanged between devices using medium access control control element (MAC-CE)-based methods or using downlink control information (DCI)-based methods. The DCI-based methods may involve relaxed timings.

  • Patent number: 11991701
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may use a downlink control information (DCI) message to indicate timing resources to a user equipment (UE) for multiple downlink data repetitions in a slot. In a first implementation, the base station may indicate an explicit time domain resource allocation (TDRA) for one repetition in the TDRA field of the DCI, and the UE may determine implicit TDRAs for the other repetitions based on the explicit TDRA. In a second implementation, the base station may indicate a total TDRA for the full set of repetitions in the TDRA field, and the UE may divide the total TDRA into individual TDRAs for the repetitions. The UE may receive the downlink data repetitions based on determining the TDRAs and may transmit a feedback message in response based on a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook.

  • Publication number: 20240161688
    Abstract: A display panel and a display device are disclosed. A first bending part is provided in a middle part of one of first connection parts in the display panel, so that a length of each of the first connection parts can be increased as much as possible within a unit area. As a result, a distribution area of the first connection parts is increased, thereby helping to reduce an amount of light transmission of the display panel. This avoids issues of light leakage and grating effect, thereby improving a display uniformity of the display panel, which is beneficial to improve a display performance.
