An error correction system includes M decoding units, each configured to perform decoding on the X first operation codes and the Y second operation codes; the decoding unit includes: a decoder, configured to receive the X first operation codes and output N first decoded signals, each corresponding to a respective one bit of the N data; a first AND gate unit, configured to receive and perform a logical AND operation on Z selected operation codes; an NOR gate unit, configured to receive and perform a logical NOR operation on (Y−Z) unselected operation codes; and N second AND gate units, each having an input terminal connected to an output terminal of the first AND gate unit, an output terminal of the NOR gate unit and one of the first decoded signals.

Methods and systems for reporting Channel State Information (CSI), including ordering of CSI in Uplink Control Information (UCI), are provided herein. According to one embodiment, a method performed in a wireless device for reporting CSI comprises at least one of: receiving an indication of a resource allocation for an UL transmission; determining, from the indication, a maximum container size for a CSI report; mapping the one or more information bits of a CSI report to a bitstream, optionally such that a first CSI subset is mapped to more significant bits than a second CSI subset; and omitting the one or more least significant bits of the bitstream.

A base station may make more efficient use of resources by transmitting data in a control region of a slot in addition to a data region. In order to avoid performance loss, the base station may adjust the data transmission in the control region in comparison to a data transmission in a data region and may signal an indication to a UE to assist the UE in receiving the data transmission in the control region. An apparatus for wireless communication at the UE receives the indication from the base station regarding the data transmission in the control region and uses the indication to perform rate matching or demodulation of the data transmission in the control region. The indication may indicate any of a different MCS/rank/TPR, a reduced MCS/rank/TPR, an MCS/rank/TPR delta, a control span for a group of UEs, and a starting symbol for the data transmission. The indication may also indicate that there is no data transmitted on resources in the control region.

Techniques are described for wireless communication. One method includes determining, based at least in part on a number of downlink component carriers (CCs) scheduled for a user equipment (UE) during a reporting interval, a number of bits to be included in a physical uplink control channel (PUCCH) acknowledgement/non-acknowledgement (ACK/NAK) payload for the reporting interval; and selecting, based at least in part on the determined number of bits, a format of the PUCCH ACK/NAK payload.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may determine a first modulation order for a first layer of a communication and a second modulation order for a second layer of the communication, wherein the first modulation order and the second modulation order are different; interleave bits for one or more of the first layer or the second layer based at least in part on the first modulation order and the second modulation order; and transmit the interleaved bits via the one or more of the first layer or the second layer. Numerous other aspects are provided.

Techniques for signaling varied modulation and coding schemes for wireless communication are discussed. A method of wireless communication may comprise receiving, by a user equipment (UE), an indication to apply a modulation order cap to determine a first modulation and coding scheme for transmission of uplink control information different from a second modulation and coding scheme for transmission of data. The method may further comprise transmitting the uplink control information using the first modulation and coding scheme, wherein the first modulation and coding scheme is determined based, at least in part, on the received indication to apply the modulation order cap.
