Measurement Reporting for Energy Saving State
A wireless device may communicate with a base station for reporting measurements of reference signals associated with one or more beams. The wireless device may use one or more adjusted configuration parameters, for example, if the base station reduces its transmission power. The wireless device may report one or more cell and/or beam measurements based on the one or more adjusted configuration parameters, which may provide improved accuracy of measurement reporting.
METHOD TO DYNAMICALLY ADJUST 4G LTE REFERENCE SIGNAL POWER TO MATCH 5G NR COVERAGE FOOTPRINT TO AVOID VOICE OVER 4G FALLBACK FAILURES FOR 5G SUBSCRIBERS
Systems and methods are provided for dynamically adjusting a 4G LTE reference signal power level to match a 5G New Radio (NR) coverage footprint to avoid voice over 4G fallback failures for 5G subscribers. Initially, a subscriber making a voice call while in NR coverage may be directed to fall back to LTE in a process known as voice over evolved packet system fallback (VoEPSFB). If the LTE signal strength is worse due to non-optimal settings of the LTE reference signal, the subscriber experiences call setup failure. After the call setup failure, the UE transitions back to the gNodeB. Since the gNodeB knows the UE attempted to fall back to LTE (as well as how soon the UE transitioned back to the gNodeB), a notification is triggered that instructs the LTE base station to increase its reference signal power level.
METHOD AND APPARATUS FOR COEXISTENCE BETWEEN LONG TERM EVOLUTION SIDELINK AND NEW RADIO SIDELINK
A method of a first terminal supporting a first radio access technology (RAT) and a second RAT may comprise: determining candidate resources by performing a resource sensing operation based on the first RAT; performing a resource selection operation based on the first RAT with respect to the candidate resources in consideration of information on resources of the second RAT; and performing sidelink (SL) communication based on the first RAT with a second terminal using resources selected by the resource selection operation based on the first RAT.
Channel Occupancy Time Sharing Between Sidelink
A first wireless device may receive, from a second wireless device, a channel occupancy time (COT) sharing indication indicating a COT duration. The first wireless device may transmit, to a third wireless device and within the COT duration, sidelink data based on a first power measurement of a first reference signal (RS) associated with a first sidelink between the first wireless device and the second wireless device, and a second power measurement of a second RS associated with a second sidelink between the first wireless device and the third wireless device.
METHOD AND APPARATUS FOR DEACTIVATING AND ACTIVATING SECONDARY BASE STATION IN WIRELESS COMMUNICATION SYSTEM
The present disclosure relates to: a communication technique for merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure relates to a method performed by a terminal in a wireless communication system, and may comprise the steps of: receiving a deactivation command regarding a secondary cell group (SCG) from a first base station related to a master cell group (MCG); performing measurement on at least one beam related to the SCG, in a deactivated state regarding the SCG; and performing a random access with a second base station related to the SCG, on the basis of a random access preamble related to a downlink beam, when beam failure is detected on the basis of the measurement.
Sidelink Resource Selection for Power Saving
A wireless device may receive one or more configuration parameters for a sidelink resource pool. The one or more configuration parameters may indicate a first resource selection procedure for the sidelink resource pool, a second resource selection procedure for the sidelink resource pool, and a priority threshold below which the second resource selection procedure is allowed. The wireless device may transmit, based on the configuration parameters, a sidelink transport block via one or more transmission resources of the sidelink resource pool.
TERMINAL AND MEASUREMENT METHOD
A terminal includes a receiving unit that receives a reference signal for acquiring a channel state and a control unit that performs measurement related to RSRP (Reference signal received power), based on a result of receiving the reference signal, and subcarrier spacing to be applied to the reference signal.
Resource Allocation Method, Device, and Storage Medium
A resource allocation method, a device, and a storage medium are disclosed. The method includes: A network device obtains a packet concurrency status of a plurality of wireless local area network WLAN devices, where the plurality of WLAN devices correspond to a same channel. The network device allocates channel resource slices to the plurality of WLAN devices from a channel resource in a first time period based on the packet concurrency status.
Beam Selection Method and Communication Apparatus
A beam selection method and a communication apparatus are provided, which relate to the field of communication technologies. The method includes: A terminal receives a downlink reference signal from a third beam of a network device on a first beam and a second beam; then, the terminal performs RSRP measurement and MPE measurement on the first beam and the second beam separately to obtain first RSRP, second RSRP, first back-off power, and second back-off power; and when a difference between the first RSRP and the first back-off power is greater than a difference between the second RSRP and the first back-off power, the terminal sends uplink data by using the first beam. In this technical solution, the terminal may select an uplink working beam with reference to the measured back-off power of the first beam and the measured back-off power of the second beam.
METHODS FOR PATHLOSS REFERENCE SIGNAL ACTIVATION
Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.
