    Abstract: There is provided mechanisms for controlling transmission from an antenna panel. The method is performed by a network apparatus. A method comprises performing time-domain beamformed communication with terminal devices served by the network apparatus using the antenna panel split into N>1 subpanels. Each subpanel has two input ports and is fed, via the input ports, by signals and configured to generate beams by application of antenna element weights to its antenna elements. The subpanels are at least phase-wise synchronized with each other. When one and the same signal is fed into the input ports of all the subpanels, signals as transmitted from the subpanels add up coherently to represent a 1-layer transmission by a time reference being shared between the subpanels. The time-domain beamformed communication is performed by the network apparatus using from 1 to 2N layers per symbol of a transmission time interval according to a mapping between the input ports and the signals as transmitted from the subpanels.

    Abstract: A system may include an access network comprising at least two base stations configured to communicate with a wireless communication device via dynamically steerable or formable beams, a resource manager disposed at a location accessible via the access network or at the wireless communication device, and an experience tester configured to determine a qualitative assessment of capabilities of the access network relative to different categories of services or applications for the wireless communication device via a first beam formed or selected to serve the communication device. The resource manager may be configured to initiate a handover based on both location-based criteria and user experience based criteria. The user experience based criteria may be associated with the qualitative assessment.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of a relaxation criterion associated with one or more reference signals used in performing at least one of radio link monitoring (RLM) or beam failure detection (BFD), wherein the relaxation criterion includes a mobility condition associated with the UE. The UE may perform, based at least in part on satisfying the mobility condition, one or more measurements using one or more of the reference signals and based at least in part on the relaxation criterion. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. A first device, such as a user equipment (UE) or base station, may receive, at a first antenna of a first antenna array, a first set of reference signals. The first device may measure the phase for each of the reference signals and estimate a linear offset between the first antenna array and a second antenna array of a second device that transmitted the reference signals. The first device may adjust an alignment of the first antenna array according to the estimated linear offset. The first device may receive a second set of reference signals, measure the phase for each of the reference signals, and estimate one or more rotational offsets between the first antenna array and the second antenna array. The first device may adjust the alignment of the first antenna array based on the one or more rotational offsets.

    Abstract: There is provided mechanisms for detecting a signal communicated by a backscattering device. A method is performed by a MIMO reader that comprises a first antenna panel and a second antenna panel. The method comprises selecting, for the first antenna panel, first spatial filter coefficients with an object to minimize interference from the first antenna panel towards the second antenna panel over a radio propagation channel. The method comprises transmitting, from the first antenna panel and whilst applying the selected first spatial filter coefficients, a first signal. The method comprises receiving, at the second antenna panel, a backscattered signal component of the first signal as backscattered by the backscattering device. The backscattered signal component comprises the signal communicated by the backscattering device. The MIMO reader thereby detects the signal communicated by the backscattering device.

    Abstract: A method, system and apparatus are disclosed. According to one embodiment, a method implemented in a WD is provided. The WD is configured to communicate with a network node, and is further configured with at least a first and a second TCI state. The first TCI state is the currently active TCI state. The method comprises receiving (S1310) an indication from the network node to switch from the first TCI state to the second TCI state; determining (S1320)whether a condition for the switch from the first TCI state to the second TCI state is met; and in response to the received indication to switch, performing (S1330) the switch to the second TCI state when determining that the condition for the switch is met, and refraining from performing (S1340) the switch to the second TCI state otherwise.Publication:
