  • Publication number: 20240113832
    Abstract: Aspects of the present disclosure allow a UE to request, in an anchor carrier on one frequency band, a base station to configure and transmit A-TRS in an SSB-less secondary carrier on a different frequency band. The UE transmits, in a first cell served by the anchor carrier, a request for A-TRS. Based on the request, the UE receives, in a second cell lacking SSB transmissions served by the secondary carrier, the A-TRS based on the request. The base station may also control transmission of the A-TRS in the SSB-less secondary cell based on a timer derived from the request. Using the A-TRS, the UE may apply AGC and time/frequency tracking loop operations prior to receiving a PDSCH in the SSB-less secondary cell, thereby improving reception performance of downlink data transmissions in the secondary carrier. Thus, network energy savings provided by SSB-less secondary carriers may be obtained in inter-band CA.

  • Patent number: 11949618
    Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

  • Patent number: 11950156
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for cancelling transmissions during handover operations. In one aspect, a user equipment (UE) can cancel at least a portion of a first uplink transmission where the first uplink transmission overlaps with a second uplink transmission scheduled by a target cell in a dual active protocol stack (DAPS)-based handover (HO). In another aspect, a network can receive, from the UE, a capability indicating whether cancelling uplink transmission from a source cell in DAPS-based HO is supported, and the network can schedule an uplink transmission for the UE during the DAPS-based HO to the target cell based on the capability.

  • Publication number: 20240107467
    Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit a set of spatially multiplexed synchronization signals in a same symbol period. The set of spatially multiplexed synchronization signals may indicate a parameter, such as a cell identifier, for the network entity. The network entity may select a sequence for each synchronization signal of the set. A user equipment (UE) may monitor for the set of spatially multiplexed synchronization signals during the same symbol period. The UE may differentiate each synchronization signal based on a respective sequence used to transmit each synchronization signal. The UE may determine that the set of spatially multiplexed synchronization signals were transmitted by the network entity using multiple antenna ports. The UE may determine the parameter for the network entity based on receiving the set of spatially multiplexed synchronization signals.
