    Abstract: Provided is a rate matching method and device for a Polar code. The method includes: concatenating K information bits and (N−K) frozen bits to generate a bit sequence of N bits, and encoding the bit sequence of N bits by means of a Polar code encoder with a generator matrix of size N×N to generate an initial bit sequence {S0, S1, . . . , SN−1} of bits, where K and N are both positive integers and K is less than or equal to N; dividing a circular buffer into q parts, selecting bits from the initial bit sequence {S0, S1, . . . , SN−1} in a non-repeated manner, and writing the bits into the q parts of the circular buffer according to a predefined rule, where q=1, 2, 3 or 4; and sequentially selecting a bit sequence of a specified length from a predefined starting position in a bit sequence in the circular buffer and taking the bit sequence of the specified length as a bit sequence to be transmitted.

    Abstract: A system and method for coding master information blocks (MIBs) for broadcast are disclosed herein. In one embodiment, a method performed by a communication node includes: identifying time sensitive bits among a master information block; placing the time sensitive bits at predetermined encoding positions, wherein the time sensitive bits at the predetermined encoding positions are encoded with a common property different than other bits of the master information block; encoding the master information block; and transmitting a broadcast message comprising the master information block.

    Abstract: Power saving techniques are described for paging operation. An example wireless communication method includes receiving, by a communication node, a signal-based wake up signal (WUS) that includes L symbols in time domain or a channel-based WUS that is included in a channel, where the signal-based WUS or the channel-based WUS is associated with the communication node or with a group to which the communication node belongs, and where the signal-based WUS or the channel-based WUS includes an indication information that indicates whether the communication node is triggered to monitor a paging occasion, and determining, by the communication node, whether to perform a paging related operation based on the indication information.

    Abstract: Methods, systems, and devices for signaling to reduce power consumption of wireless devices in power saving modes are described. An example method for wireless communication includes transmitting, by a network node to a wireless device in communication with the network node, a control information that is based on the wireless device being in a power-saving state that is different from a power-normal state. Another example method for wireless communication includes receiving, by a wireless device from a network node, a control information that is based on the wireless device being in a power-saving state that is different from a power-normal state.

    Abstract: Provided is a method and an apparatus for encoding CSI, a storage medium, and a processor, where the method includes: placing a first type of information bits of the CSI in a first type of position indexes of the position index set, and determining, from the indexes other than the first type of position indexes determined by the first type of information bits in the position index set, indexes of the second type of information bits of the CSI, indexes of the third type of information bits of the CSI, and indexes of the fourth type of information bits in the position index set; or placing the fourth type of information bits in the fourth type of position indexes of the position index set, and determining indexes of the first type of information bits, indexes of the second type of information bits, and indexes of the third type of information bits of the CSI in the position index set from indexes other than the fourth type of position indexes determined by the fourth type of information bits in the position index set. The present disclosure solves the problem that positions of various types of information in the CSI reporting cannot be reasonably mapped in the related art.
