  • Publication number: 20240187078
    Abstract: Aspects of the disclosure relate to beam sweeping with controllable reflective surfaces in the presence of co-located base stations of different network operators. A first base station that is co-located at a site with a second base station may perform a first beam sweep. The first beam sweep includes transmitting a plurality of directional beams. The first base station further transmits a control signal to a controllable reflective surface to control the controllable reflective surface to reduce a likelihood of a redirection of a directional beam of a potential second beam sweep by the second base station towards a user equipment associated with the second base station. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 11985524
    Abstract: A configuration for a UE that measures CLI to determine the reception timing of the CLI signal transmitted from a UE in another cell. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of measuring CLI signals by improving the manner in which a wireless device determines the reception timing of a transmitted CLI signal. An apparatus receives a first downlink signal from a first base station. The apparatus receiving a second downlink signal from a second base station. The apparatus determines a CLI signal measurement from a second UE received at the first UE based on a propagation delay difference, the propagation delay difference being based on the first downlink signal and the second downlink signal.

  • Patent number: 11968662
    Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.

  • 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.

  • Patent number: 11943756
    Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time.

  • Patent number: 11943715
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.

  • Publication number: 20240098599
    Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive, from a base station, an indication of a degree of UE loading for at least one of a set of reconfigurable reflective surfaces that are configured to assist in communications between the UE and the base station. The UE may select a reconfigurable reflective surface for use in the communications between the UE and the base station based on the degree of UE loading of the selected reconfigurable reflective surface, and transmit a signal to the base station via the selected reconfigurable reflective surface. In some cases, the UE may receive, from the base station, an indication for the UE to use a different reconfigurable reflective surface than the selected reconfigurable reflective surface, and may transmit a second signal to the base station via a second reconfigurable reflective surface based on the indication.
