Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for segmenting uplink control information prior for encoding using a polar code prior to transmission. An exemplary method that may be performed by a wireless device generally includes iteratively segmenting a group of K information bits into a plurality of segments, encoding the information bits of each of the plurality of segments using a polar code to generate a plurality of encoded segments, and transmitting the plurality of encoded segments.

This application relates to the field of wireless communications, and in particular, to a communication method, an apparatus, and a system in a wireless communications system. In the method, a network device and a terminal device determine M resource element group bundles in a control resource set. The network device sends a control channel on resources corresponding to the M resource element group bundles. The terminal device detects the control channel on the resources corresponding to the M resource element group bundles, where M is greater than or equal to 1. The control resource set includes B resource element group resource element group bundles. By using the method, resource configuration efficiency in a communications system is improved.

In one exemplary aspect, a method for wireless communication is disclosed. The method can include receiving, at a terminal configured to perform a number of transmission repetitions according to a rule, a first message from a network node, the first message including an indication to modify at least one transmission repetition of the number of transmission repetitions according to the rule. The method can also include modifying, by the terminal, the at least one transmission repetition of the number of transmission repetitions identified in the first message.

Systems, methods, and circuitries are provided for performing sidelink communication. An example method indicates a frequency resource reservation in sidelink control information (SCI). The method includes identifying a transport block (TB) for transmission to a UE; determining a total number of sub-channels (N.sup.SL) in a resource pool for sidelink communication, a number of sub-channels (L.sub.sub) of the TB, a first starting sub-channel index x.sub.1 of a first retransmission of the TB, and a second starting sub-channel index x.sub.2 of a second retransmission of the TB. The method includes determining a frequency resource indication value (FRIV) based on N.sup.SL, L.sub.SUB, x.sub.1, and x.sub.2, wherein the FRIV represents a result of a predetermined function of L.sub.sub, x.sub.1, and x.sub.2 that generates a unique value for possible combinations of L.sub.sub, x.sub.1, and x.sub.2. The FRIV is encoded in SCI and the SCI is transmitted to the UE.

The present invention relates to a method for transmitting a packet in a communication system, the method comprising: generating drop information indicating at least one source packet to be dropped among source packets to be transmitted and whether or not to drop each of the other source packets except the at least one source packet; performing forward error correction (FEC) encoding on the drop information and the other source packets except the at least one source packet; generating a repair packet comprising repair data for restoring the drop information and a repair symbol for restoring the other source packets except the at least one source packet; and transmitting the other source packets except the at least one source packet and the repair packet.

The present disclosure provides an information processing method and apparatus. A terminal device encodes uplink control information (UCI) to obtain coded bits of the UCI, and encodes data to obtain coded bits of the data. The terminal device multiplexes the coded bits of the UCI and the coded bits of the data to obtain a multiplexed bit sequence. The terminal device then transmits the multiplexed bit sequence to a network device via a physical uplink shared channel (PUSCH). A length of a transmission time interval of the UCI is less than or equal to 0.5 millisecond. In this way, data transmission latency can be reduced.

A data processing system may include a memory module; and a controller configured to exchange data with the memory module in response to a request received from a host. The controller divide a first data into a first data group to error correction and a second data group not to error correction in response to the first data and a first data write request received from the host, generates a first meta data for error correction for the first data group, configures a first data chunk that includes the first data and the first meta data, and transmits the first data chunk to the memory module.

The present disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communications. A UE receives first information, the first information being used for indicating M DCI blind decoding(s); monitors a first-type radio signal respectively on each of S sub-band(s) in a first time-domain resource; and performs at most M1 DCI blind decoding(s) of the M DCI blind decoding(s) on the S sub-band(s) in the first time-domain resource. Herein, the first-type radio signal detected on the S sub-band(s) is used for determining the M1 DCI blind decoding(s) out of the M DCI blind decoding(s). The above method allows the base station to make dynamic adjustments to the UE's blind decoding on PDCCH resources according to LBT results, ensuring that sufficient PDCCH resources are available and not too many PDSCH resources are preempted, and that excessive blind decodings can be avoided.

The present disclosure relates to a wireless communication system and, specifically, to a method and a device therefor, the method comprising the steps of: obtaining information on a plurality of search space sets and a plurality of groups including parts of the plurality of search space sets; obtaining information on one group for monitoring a PDCCH from among the plurality of groups; and monitoring the PDCCH on the basis of search space sets which satisfy a pre-defined condition from among search space sets corresponding to the one group, wherein the pre-defined condition includes a condition where the number of PDCCH candidates and the number of non-overlapping control channel elements (CCEs) are less than or equal to specific values.

A method and apparatus for transmitting and receiving sidelink feedback information. The method includes: receiving, by a terminal equipment, DCI with CRC being scrambled by a SL-RNTI or a SL-CS-RNTI; generating first indication information used for indicating that the first sidelink transmission is successful or that a network device is not needed to schedule retransmission, wherein the first sidelink transmission is not performed on the dynamic grant resource scheduled by the DCI, and a priority of the first indication information is preconfigured; and transmitting the first indication information via a first PUCCH indicated by the DCI.
