A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes the UE receiving and/or monitoring a first control region via a first link. The method further includes the UE transmitting a first request if the first link fails. The method also includes the UE receiving and/or monitoring a second control region for a response via a second link within a time window associated with the first request. In addition, the method includes the UE receiving and/or monitoring the first control region after the time window associated with the first request is over.

Methods, systems, and devices for wireless communications are described for autonomous block error rate (BLER) threshold determination fur use in beam failure indication (BFI) procedures. A user equipment (UE) that is capable of autonomously determining a BLER threshold value may provide an indication of the capability to a base station. The base station may provide configuration information that enables the UE to perform autonomous BLER threshold determination, and the UE may determine the BLER threshold value based on the configuration information. The UE may determine that a BFI has occurred based on the determined BLER threshold, and thereby enhance beam failure detection procedures to provide more efficient and reliable communications.

A method of transmitting and receiving data in a wireless communication system and a device therefor are disclosed. Specifically, the method performed by a user equipment (UE) may comprise transmitting, to a base station, capability information including (i) first information indicating a decoding level of the UE and (ii) second information indicating whether a machine learning is possible, receiving decoding level information from the base station based on the first information, and receiving the downlink data from the base station based on the decoding level information and the second information.

Systems, methods, and instrumentalities are described herein for supporting CBG-based retransmission with variable CBG size using variable length HARQ-ACK. A WTRU may receive a configuration to use a first table. The first table may be associated with a maximum number of code block groups per transport block (maxCBG/TB). The WTRU may determine a number of HARQ-ACK bits to send for code blocks. The determination may depend on whether an indication is received to switch from the first table to a second table. On a condition that the indication to switch from the first table to the second table is received, the WTRU may send a number of HARQ-ACK bits that is equal to two times the maxCBG/TB. The WTRU may receive a retransmission of a number of code blocks, wherein a code block group size depends on a sent number of HARQ-ACK bits.

This disclosure provides a sidelink power control method and a terminal device. The method is applied to the terminal device, and includes: sending information to a first terminal device in sidelink communication, so that the first terminal device generates power control indication information based on a receiving status of the information; receiving the power control indication information from the first terminal device; and determining an information transmit power of the terminal device in the sidelink communication according to the power control indication information.

A method for pseudo channel hopping in a node of a wireless mesh network is provided that includes scanning each channel of a plurality of channels used for packet transmission by the node, wherein each channel is scanned for a scan dwell time associated with the channel, updating statistics for each channel based on packets received by the node during the scanning of the channel, and selecting a channel of the plurality of channels for scanning based on the statistics when the scan dwell time of a currently scanned channel ends.

Technologies directed to improving power for wireless transceivers are described. One method determines, in a first mode, a first value associated with a wireless link and a second values associated with the wireless link, the first value being indicative of a first metric and the second value being indicative of a second metric different from the first metric. The first value and the second value collectively indicate a category of channel quality for the wireless link. The method determines that the wireless device can operate in a second mode for subsequent data based on the category of channel quality, wherein in the second mode the wireless device consumes less power than in the first power mode. The method receives, in the second mode, second data over the wireless link.

An apparatus for handling an incoming communication data frame containing a plurality of bits is provided. The apparatus may include a plurality of data matchers, each data matcher configured to compare a subset of the plurality of bits of the communication data frame with a predetermined data pattern of a plurality of data patterns and to provide a data matcher output to indicate the result of the data matcher comparison, a plurality of selectors, each selector configured to compare a subset of the data matcher outputs of the plurality of data matchers with a predetermined selection pattern of a plurality of selection patterns and to provide a selector output to indicate the result of the selector comparison, and a frame filter configured to transfer the incoming frame to application logic only if the selector outputs of the plurality of selectors match a predetermined filter pattern, and to also transfer the selector outputs of the plurality of selectors to the application logic.

A method and a system for correcting cyclic redundancy check (CRC) for a frame with last bytes changed are provided. The method includes acquiring a data frame, calculating a CRC of a modified data frame, and determining a corrected CRC for the data frame based on at least the CRC of the modified data frame and a CRC correction field calculated on the bytes to be replaced at the end of the frame. An altered data frame includes the data frame with a number of last bytes of the data frame replaced with new bytes.
