摘要： Various solutions for enhanced closed access group (CAG) selection in manual network selection mode are described. An apparatus (710, 720) may determine that the apparatus supports CAG and operates in a manual network selection mode. The apparatus (710, 720) may detect a CAG cell associated with a CAG identifier (ID) (113) in an allowed CAG list. The apparatus (710, 720) may indicate to a user whether the CAG ID (113) is authorized based on time validity information associated with the CAG ID (113) in the allowed CAG list.

摘要： A method for signaling an improved receive (Rx) performance report of victim bands includes: configuring a signaling message to indicate the improved Rx performance report, and sending the signaling message. The improved Rx performance report includes information of K improved Rx performance indicators being only a subset of M improved Rx performance indicators of a user equipment (UE), where K and M are positive integers, M is larger than K, and K is not smaller than one.

摘要： A system to operate as a phase locked loop (PLL) includes a frequency synthesizer in a feedback path of the PLL and a delay line arranged to receive an output of the frequency synthesizer. A retimer subsystem is arranged to receive the output of the frequency synthesizer. A digitally controlled delay line (DCDL) is arranged to receive an output of the retimer. A phase detector is arranged to receive an output of the delay line and an output of the DCDL and to provide an error signal indicating a difference in phase of the output of the delay line relative to the output of the DCDL. A controller causes closed loop operation of the PLL during a normal operational mode and open loop operation during a calibration mode during which gain of the DCDL, defining a relationship between a control code and a resulting delay, is calibrated.

摘要： A power-up initialization circuit includes a delay chain circuit and a signal generator circuit. The delay chain circuit receives a power supply voltage, and applies a predetermined delay amount to the power supply voltage for generating a delayed output voltage. The signal generator circuit receives the delayed output voltage from the delay chain circuit, and generates and outputs at least one power-up initialization signal in response to the delayed output voltage.

摘要： Techniques pertaining to narrow bandwidth transmission schemes in next-generation Enhanced Long Range, ELR, wireless local area networks, WLANs, are described. An apparatus, e.g., station, STA, generates a physical-layer protocol data unit, PPDU, comprising a spoofing preamble, an ELR preamble and an ELR data portion (3210). The apparatus transmits the PPDU in an ELR wireless communication such that at least a portion of the ELR preamble is transmitted on at least one narrow-bandwidth subchannel of a wider bandwidth (3220).

摘要： Method and user equipment, UE, are provided for CSI compression based on multi-dimensional MIO RF signature. In one novel aspect, the UE receives CSI-RS (701), estimates a basis matrix and a coefficient matrix of a downlink channel matrix based on the at least one CSI-RS, wherein the basis matrix is an N-dimensional non-orthogonal matrix, with N greater than two, and the coefficient matrix is a linear combination coefficient matrix for the basis matrix (702), and transmits to the network at least one feedback comprising feeding back the basis matrix in a first periodicity and feeding back the coefficient matrix in a second periodicity (703). In one embodiment, the UE compresses the basis matrix and the coefficient matrix to a feedback basis matrix and a feedback coefficient matrix before transmitting.

摘要： The present invention provides a control method of a wireless communication module having a first link and a second link. The control method includes the steps of: obtaining a first timestamp of a first reference point (202) corresponding to a first PPDU, wherein the first PPDU is transmitted on a channel corresponding to the first link; obtaining a second timestamp of a second reference point (206) corresponding to the second link, wherein the second reference point is a slot boundary, a transmission end or a reception end; determining a length of a second PPDU (210) according to the first timestamp and the second timestamp, to make an end of the second PPDU is aligned to an end of the first PPDU; and generating the second PPDU according to the determined length of the second PPDU, and transmitting the second PPDU after the second reference point (212).
