A gear shifting technique has been developed in which modulation and equalization are shifted to achieve optional performance. In one form, two or more equalizers, each associated with a demodulator and message decoder, determine if the modulation being used can be increased in complexity in order to increase the channel throughput or determine if the modulation method should be reduced in complexity in order to improve the receiver error performance. The quality metrics can based on which equalizer-demodulator-decoder is set to first detect a valid message. Other factors can be considered with this technique such as a packet-error ratio and a signal-to-noise ratio. In a financial trading system, message erasures can be favored over errored messages by limiting the number of bit or symbol corrections permitted per message to less than the maximum possible for the selected decoding schemes.

A wireless telecommunication system has a base station arranged to communicate messages to one or more terminal devices over a radio interface. The radio interface has a radio frame structure having a plurality of subframes, and a message may be transmitted in accordance with a first transmission scheme or transmitted in accordance with a second transmission scheme. The message may be transmitted in association with an identifier to indicate a terminal device to which the message is addressed. A characteristic for the identifier, for example a value or control region search space for the identifier, is dependent on whether the message is to be transmitted in accordance with the first transmission scheme or the second transmission scheme. A terminal device to which the message is addressed determines the transmission scheme from the characteristic of the identifier and receives the message accordingly.

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.

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.
