Provided are a channel encoding method and a control device. In the channel encoding method, a control device sends configuration information to a controlled device, wherein the configuration information is used for configuring one of the following: a channel encoding manner corresponding to at least one semi-persistent scheduling configuration; a channel encoding manner corresponding to a first transport block, with the number of bits of the first transport block being less than a first threshold value and greater than a second threshold value; and a channel encoding manner corresponding to a first downlink control channel.

A method and a device for performing uplink transmission or reception in a wireless communication system are disclosed. A method for performing uplink transmission by a terminal according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, configuration information including N1 pieces of first infomlation related to unicast SPS transmission and N2 pieces of second information related to multicast SPS transmission; and transmitting, to the base station, first HARQ-ACK information associated with N1 pieces of unicast SPS transmissions and second HARQ-ACK information related to N2 pieces of multicast SPS transmissions, the first and second HARQ-ACK information being multiplexed on a first PUCCH, wherein the first HARQ-ACK information and the second HARQ-ACK information are multiplexed on the first PUCCH on the basis of the ascending order of the indexes of the N1 pieces of first information and the N2 pieces of second information.

Embodiments of this application provide a data transmission method and an apparatus. When a time-frequency resource used by a terminal device for data transmission is unavailable, the terminal device postpones, based on indication information of a network device and/or according to a postponement rule, the data transmission to a time-frequency resource closest to the time-frequency resource. Therefore, a data transmission latency is reduced.

A UE can receive a PDCCH for scheduling a first PDSCH on a serving cell. The UE can receive the first PDSCH from among a plurality of SPS PDSCHs and the first PDSCH on the basis of that i) the first PDSCH overlaps, with respect to time, with the plurality of SPS PDSCHs that are required to be received on the serving cell, and ii) a PDCCH ends at least 14 symbols before the start symbol of the earliest SPS PDSCH from among the plurality of SPS PDSCHs.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) or a base station may be configured to indicate that a transmission occasion is empty while operating in a full-duplex mode. In some examples, the UE may transmit, to the base station, an indication that an uplink transmission occasion (for example, a configured grant transmission occasion) will not be used by the UE for transmitting an uplink communication. In some other examples, the base station may transmit, to the UE, an indication a downlink transmission occasion (for example, semi-persistent scheduling transmission occasion) will not be used by the base station for transmitting a downlink communication. If uplink or downlink transmission occasions are empty, the UE and the base station may each update parameters to operate in a half-duplex mode.

Various aspects include a method for preserving a msg3 transmission. The method may include receiving, by a UE device, from a base station, a CI that overlaps with the msg3 transmission. Responsive to receiving the CI, the msg3 transmission is not canceled. Another method disclosed herein includes continuing an RA procedure. The method may include encoding a first part of the msgB. The method may include encoding a second part of the msgB. The method may include attempting to decode, by the UE device, the first part of the msgB. The method may include attempting to decode, by the UE device, the second part of the msgB. Based on successfully decoding of the first part of the msgB, and unsuccessfully decoding of the second part of the msgB, the method may include continuing the RA procedure.

The present disclosure relates to a method and apparatus for performing grant-free transmission and reception in a wireless communication system, and a grant-free reception method performed by a terminal in a mobile communication system according to an embodiment of the disclosure includes receiving, from a base station, configuration information related to downlink semi-persistent scheduling (SPS) and configuration information related to a data indication signal (DIS), receiving, from the base station, downlink SPS activation indication information, monitoring the DIS based on the configuration information related to the DIS, and when the DIS is detected or when the DIS is detected and monitoring indication information for a downlink data channel is obtained from the DIS, monitoring the downlink data channel based on at least one of the configuration related to downlink SPS and the downlink SPS activation indication information.

A multicarrier scheduling method and apparatus, and a device, are provided. The method includes: receiving DCI sent by a network device, where the DCI is used to indicate to schedule semi-persistent configurations on M carriers, or indicate to schedule semi-persistent configurations on X carriers and schedule dynamic configurations on Y carriers, and the M carriers, the X carriers, and the Y carriers are all carriers in N carriers on which the DCI supports scheduling; and both M and N are integers greater than or equal to 2, both X and Y are positive integers, M is less than or equal to N, and a sum of X and Y is less than or equal to N.

Systems, methods, apparatuses, and computer program products for handover optimization using time sensitive communication assistance information. The method may include, receiving, from a network element, a handover request message or a context message. At least one of the handover request message or the context message may include time sensitive communication assistance information. The method may also include at least one of performing an admission control procedure based on the time sensitive communication assistance information, and scheduling data transmission with a user equipment based on the time sensitive communication assistance information.
