Abstract: Aspects relate to measuring interference associated with sidelink communication. A UE that supports full-duplex communication may transmit on a first frequency resource and conduct self-interference measurements on a second frequency resource (e.g., a guard band) adjacent to the first frequency resource. Provisions may be made to ensure that other nearby wireless communication devices do not transmit on the second set of frequency resources when the UE is conducting an interference measurement. In a first resource allocation mode, a base station that allocates full-duplex resources for a first UE may ensure that any UEs that are near the first UE are not scheduled to transmit on a guard band when the UE is conducting an interference measurement. In a second resource allocation mode, a UE may reserve resources that are predefined with a guard band or the UE may reserve resources and use a subset of the resources for interference measurements.

Abstract: An apparatus includes a battery pack with N battery bricks, each with a DC output voltage. The output of each brick is connected in series providing a bus voltage. Each brick includes battery power modules (“BPMs”) connected in parallel and each connected to a battery cell. Each BPM charges/discharges the connected battery cell. Each brick has a battery brick controller that provides a control signal to each brick's BPMs. A control signal of a BPM is derived from a BPM error signal that includes a battery cell current of the battery cell of BPM subtracted from a summation of an average current signal, a local droop current and a balancing current. The balancing current is based on a current SOC of the battery cell connected to the BPM and a desired SOC for the battery cell connected to the BPM. A BMS derives the balancing current for the BPMs.

Abstract: The present technology pertains to a group-based network policy using Segment Routing over an IPv6 dataplane (SRv6). After a source application sends a packet, an ingress node can receive the packet, and if the source node is capable, it can identify an application policy and apply it. The ingress node indicates that the policy has been applied by including policy bits in the packet encapsulation. When the packet is received by the egress node, it can determine whether the policy was already applied, and if so, the packet is forward to the destination application. If the egress node determines that the policy has not be applied the destination application can apply the policy. Both the ingress node and egress nodes can learn of source application groups, destination application groups, and applicable policies through communication with aspects of the segment routing fabric.

Abstract: Methods, systems, and devices for wireless communications are described. A full-duplex device may perform a channel access procedure using multiple threshold values to determine whether self-interference at the full-duplex device is affecting the channel access procedure. For example, if a first amount of energy detected during a first sensing operation of the channel access procedure is determined to be between a first threshold value and a second threshold value, the full-duplex device may perform a self-interference measurement on the shared channel and may transmit on the shared channel if the self-interference measurement exceeds a self-interference threshold value. Additionally or alternatively, if the self-interference measurement does not exceed the self-interference threshold value, the full-duplex device may refrain from transmitting on the shared channel.

Abstract: A user equipment (UE), such as a full-duplex UE, may receive a downlink transmission from a first transmit-receive point (TRP) in a full-duplex multi-TRP configuration. The UE may perform an uplink transmission to a second TRP in the full-duplex multi-TRP configuration based at least in part on a timing advance adjustment associated with the uplink transmission. The UE may apply the timing advance adjustment based at least in part on an indication received from a base station. The indication may be to set a timing advance offset to a value that satisfies a threshold value based at least in part on the downlink transmission and the uplink transmission being associated with two different TRPs. The downlink transmission and the uplink transmission may not be separated by a guard symbol when the downlink transmission and the uplink transmission are associated with the two different TRPs, which may improve a resource utilization.

Abstract: In a wireless network, a user equipment (UE) may skip an uplink transmission associated with a dynamic uplink grant. In such cases, when the UE skips an uplink transmission that would have been concurrent with a downlink transmission, the UE may perform one or more mode-dependent control operations. For example, because the uplink transmission would result in a full-duplex operation if the UE were to perform the uplink transmission, the UE may reset a timer associated with switching from a full-duplex mode to a half-duplex mode and/or perform one or more mode-dependent control operations in the full-duplex mode. Alternatively, because the UE refrains from performing the uplink transmission that would have resulted in a full-duplex operation, the UE may maintain the timer associated with switching from the full-duplex mode to the half-duplex mode and/or perform the one or more mode-dependent control operations in the half-duplex mode.
