摘要： Methods and apparatus are described for adapting wake-up signal monitoring to optimize power saving performance. In one embodiment, a UE can be configured to selectively skip WUS monitoring based on a current UE context. In another embodiment, WUS/PDCCH monitoring and/or other UE procedure can be adapted based on a statistic related to the wake-up signals transmitted by the base station to the UE.

摘要： Methods and apparatuses are disclosed for wireless device (WD)-autonomous physical downlink shared channel (PDSCH) receiver (RX) antenna adaptation. In one embodiment, a method implemented in a WD includes one or more of: estimating an expected number of multiple-input multiple-output (MIMO) layers based at least in part on channel state information (CSI) and/or a sounding reference signal (SRS) configuration; determining a set of antennas of a plurality of antennas to use based at least in part on the estimated expected number of MIMO layers; and/or receiving a MIMO signal using the determined set of antennas. In one embodiment, a method implemented in a network node include receiving a channel state information (CSI) report from the WD; and/or scheduling and/or transmitting a downlink (DL) channel to the WD using a number of multiple-input multiple-output (MIMO) layers, the number of MIMO layers used based at least in part on the received CSI report.

摘要： Embodiments include methods for cell reselection by a user equipment (UE) in a wireless network. Such methods include determining one or more first resources associated with transmission of connected-state reference signals (RS) by the wireless network in the UE's serving cell and/or in one or more neighbor cells while the UE is in a non-connected state. Such methods include using the one or more first resources, performing cell reselection measurements on the connected-state RS transmitted in the serving cell and/or in any of the neighbor cells. Other embodiments include complementary methods for a network node, as well as UEs and network nodes configured to perform

摘要： Embodiments include methods, performed by a user equipment (UE), for uplink (UL) transmission in a wireless network. Such methods include receiving a configuration associated with an UL transmission to a network node in the wireless network. Such methods include, for each of a plurality of combinations of the UE's available antennas and transmitters, determining metrics based on the UE performing the UL transmission using the particular combination. The metrics include a quality metric associated with reception of the UL transmission by the network node, and a UE energy consumption metric. Such methods include selecting one of the plurality of combinations of the available antennas and transmitters based on the respective quality metrics and the respective UE power consumption metrics, and performing the UL transmission according to the configuration and using the selected combination of available antennas and transmitters. Other embodiments include UEs configured to perform such methods.

摘要： One or more network nodes are configured for operation in a wireless communication network and, specifically, are configured to provide for co-existence between radar-scanning operations of a radar-enabled UE and network communications, where the radar transmissions are in a same or overlapping frequency range as regards the network communications. In an example implementation, a radio network node, referred to as an CONFIGURE ONE OR MORE access point or base station supports coexistence between radar sensing and network communications that are subject to interference from the radar sensing.

摘要： A method of beamforming calibration is disclosed for a multi-antenna transceiver configured to communicate with one or more other transceivers. The multi-antenna transceiver has a plurality of transceiver chains connectable to respective antenna elements of the multi-antenna transceiver. Each transceiver chain comprises a transmitter path and a receiver path. The method comprises (for each transceiver chain) feeding an analog signal from the transmitter path to the receiver path via connection circuitry between the transmitter path and the receiver path to provide a digital calibration signal, and determining a beamforming calibration factor for the transceiver chain based on the digital calibration signal. Corresponding apparatus, multi-antenna transceiver, wireless communication node, and computer program product are also disclosed.

摘要： A method is disclosed of paging a user equipment (UE) by a network node. The network node is configured for beam-formed transmission of a plurality of beams, wherein each beam is associated with a corresponding synchronization signal block (SSB), and wherein a physical downlink control channel (PDCCH) paging monitoring occasion (PMO) is associated with a preceding SSB. The method comprises determining (while the UE is in a non-connected mode) a subset of the plurality of beams related to one or more beams previously associated with the UE, transmitting the corresponding SSB for each beam of the plurality of beams, and paging the UE only in PDCCH PMO:s associated with the corresponding SSB:s of the beams of the subset. Corresponding apparatus, network node and computer program product are also disclosed.

摘要： A base station or other network node configures a network transmission in dependence on a directional scanning reception ability of a wireless communication device targeted by the transmission. An example transmission configuration is selecting or restricting which Transmission/Reception Point to use for the transmission or selecting or restricting the beamforming configuration to use for the transmission. The device complements operations in the wireless communication network by indicating its directional scanning reception ability in initial signaling, such as used for random access, or in Radio Resource Control signaling, or both.
