摘要： A first network node in a first radio area network (RAN) is configured to communicate with at least a second node in a second RAN. The first node is configured to establish scheduling for a transmission from the first node to a wireless device (WD) based at least in part on scheduling of the second node for another transmission to the WD. The first node may be configured to change scheduling for the first node faster than scheduling for the second node. The first RAN may be based on 3rd Generation Partnership Project (3GPP), New Radio standards, and the second RAN based on 3GPP Long-Term-Evolution standards. The first node may set a timing parameter for a transmission such that a multi-slot time window exists to convey to the first node information about an uplink scheduling decision the second node has made for an uplink slot.

摘要： Methods and apparatus are provided for calibrating an antenna array in a receiver. A training signal for calibrating the antenna array is injected into a data signal received on each receive path to generate combined signals on each receive path. The combined signals are equalized by respective equalizers. The coefficients of the equalizers are determined by comparing a feedback signal for each receive path with the equalized signal to estimate the impairment on each received path. The estimated impairment on each receive path is used to adapt the equalize coefficients for a respective equalizer to compensate for the impairment. After equalization, an estimate of the observed training signal on each receive path is subtracted from the equalized signal for the same receive path to generate estimates of the received data signals for demodulation and decoding.

摘要： Systems and methods are disclosed herein for dynamic switching between legs in Carrier Aggregation (CA). In one embodiment, a method performed by a wireless communication device comprises operating to be configured for CA with a Primary Cell (PCell) and a Secondary Cell (SCell) and to configure a first Data Radio Bearer (DRB) associated to a first logical channel and a second DRB associated to a second logical channel. The method further comprises receiving a first parameter that restricts transmission for the first logical channel to the SCell and a second parameter that restricts transmission for the second logical channel to the PCell. The method further comprises receiving a dynamic indication that the SCell is deactivated, receiving an UL grant for the PCell, selecting data from either the first or second logical channel for transmission using the UL grant, regardless of the first and second parameters, and transmitting the selected data.

摘要： A method and apparatus for calibrating an antenna array are described. Input signals and feedback signals are received, where the feedback signal is a combination of the input signals as captured after having traversed transmit paths and prior to being transmitted at a plurality of sub- arrays. A first interference reduced feedback signals is determined. A current estimation of the impairment function is determined. A second interference reduced feedback signals based on the current estimation of the impairment function, the input signals and the feedback signal. Responsive to determining that the power of the second interference reduced feedback signal satisfies a selection criteria, the current estimation of the impairment function is caused to be used for each one of the plurality of transmit paths for calibration of the antenna array and removing distortion.
