  • Patent number: 11917591
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for identification of a slot format for a set of slots where at least one slot format of the set is an subband full-duplex slot (e.g., includes uplink and downlink resources separated in a frequency domain). The base station may transmit one or more semi-persistent scheduling configurations to a UE. The UE may identify semi-persistent scheduling occasions for receiving a downlink communication based at least in part on the SPS configurations matching the format of the slot, the periodicity of the slot formats of the set, or other considerations. The UE and the base station may communicate based at least in part on the determined semi-persistent scheduling occasions.

  • Patent number: 11917668
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more communication patterns from a base station. The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross-link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.

  • Patent number: 11916844
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a downlink message via multiple receive antennas including a first group of receive antennas associated with a first antenna panel and a second group of receive antennas associated with a second antenna panel. The UE may generate two or more CSI reports based on receiving the downlink message, where each CSI report is associated with at least one of the first antenna panel or the second antenna panel. The UE may select at least one of the two or more CSI reports to transmit to the base station. In some examples, the UE may receive (e.g., via control signaling) a CSI report configuration and may select the at least one CSI report for transmission based on the CSI report configuration.

  • Publication number: 20240064720
    Abstract: Aspects relate to sub-band full duplex (SBFD) resource allocation. In an aspect, a network entity configures SBFD frequency resources for one or more sub-bands based on a size of the sub-bands and a size of a bandwidth part (BWP) associated with a user equipment (UE), and provides scheduling information to the UE in which the scheduling information includes a configuration of the SBFD frequency resources based on the size of the sub-bands and the size of the BWP associated with the UE. In another aspect, a UE receives scheduling information that includes a configuration of SBFD frequency resources for one or more sub-bands in which the configuration is based on a size of the sub-bands and a size of a BWP associated with the UE. The UE then communicates with a network via the SBFD frequency resources based on the scheduling information.

  • Patent number: 11910357
    Abstract: Aspects of the present disclosure include methods and devices for informing a base station of autonomously selected SL resources to allow the base station to adjust the DL transmission to mitigate the degradation of the reception of a DL transmission due to self-interference that overlaps with a SL transmission. A device may be configured to select resources for a SL transmission and to transmit, in an UL transmission to a base station, an indication of the resources selected for the SL transmission. A base station may be configured to receive, in an UL transmission, an indication of resources selected for a SL transmission from a UE, and to transmit, based on the indication of the resources selected for the SL transmission, at least one DL transmission that overlaps in time with the SL transmission.

  • Patent number: 11910326
    Abstract: During an uplink TDD slot, an UL UE transmits an UL signal that occupies a slot frequency range. Similarly, during a DL TDD slot, a DL UE receives a DL signal that occupies the slot frequency range. But during an SBFD slot, a UL UE transmits a UL signal that occupies only a first sub-band of the slot frequency range. Similarly, a DL UE receives a DL signal during an SBFD slot that occupies only a second sub-band of the slot frequency range. The second sub-band is distinct from the first sub-band. The DL UE may thus mitigate UE-to-UE interference during an SBFD slot by filtering the DL signal to substantially block the second sub-band from being received at the DL UE.

  • Patent number: 11910434
    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a configuration for performing channel sensing. The configuration may include one or more parameters corresponding to a processing time associated with the channel sensing. The UE may adjust the processing time associated with the channel sensing based on the one or more parameters and a full duplex capability of the first UE. The UE may transmit, using a first set of resources, a sidelink message based on the adjusted processing time. In some examples, the UE may transmit a first data message associated with a first priority level and perform channel sensing for a second data message associated with a second priority level that is higher than the first priority level. The UE may drop the first data message, skip an interference cancellation, or a combination thereof.
