To support devices with different bandwidth capabilities, a base station configures a first initial bandwidth part (BWP) of a first width within a bandwidth of the first cell (1002) and configures a second initial BWP of a second width, within the bandwidth of the first cell (1004). The base station transmits an indication of the first BWP in the first cell and an indication of the second BWP in the first cell or a second cell, to cause a first user equipment UE having a first bandwidth capability to access the first BWP, and a second UE having a second bandwidth capability to access the second BWP (1006).

Described are embodiments for uplink beam reporting. A wireless device determines an overlap in time between: a first uplink channel resource of a permissible exposure report for a cell and a second uplink channel resource of a channel state information (CSI) report for the cell. Based on the determined overlap in time, the wireless device drops the CSI report scheduled for transmission via the second uplink channel resource, and transmits the permissible exposure report via the first uplink channel resource.

Provided in the present invention are a method performed by user equipment, and user equipment. The method comprises: determining sidelink resource pool configuration information to be first configuration information (S101); receiving, from another user equipment, sidelink control information (SCI) and a corresponding or associated physical sidelink shared channel (PSSCH) (S102); and determining a cyclic shift of a physical sidelink feedback channel (PSFCH) corresponding to the PSSCH.

Embodiments of the present invention provide a communication method and apparatus, for use in improving the transmission performance of an uplink signal. The communication method provided in the embodiments of the present invention comprises: determining information of at least one sub-band in a frequency-domain resource according to a transmission parameter for uplink signal transmission and/or parameter information of the frequency-domain resource. By means of the method, a terminal or a network device can determine the information of the sub-band. Therefore, frequency selective precoding transmission can be performed by using the determined sub-band information, thereby achieving the purpose of improving the transmission performance of the uplink signal.

Disclosed are a communication technique which merges, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. A method for a terminal of a communication system may comprise the steps of: receiving, from a base station, information indicating LBRM; identifying a parameter related to the maximum number of layers for one transport block; identifying the maximum number of layers for the one transport block on the basis of the parameter; identifying a transport block size to which the LBRM is applied, on the basis of the determined maximum number of layers; and transmitting or receiving data to or from the base station on the basis of the transport block size.

Certain aspects of the present disclosure provide techniques that may for configuration of parameters for monitoring for a combination downlink control information (DCI) that schedules data and/or reference signal transmissions in multiple cells. An example method generally includes determining, a blind decode (BD) limit and a control channel element (CCE) limit based on a scaling factor less than one, determining physical downlink control channel (PDCCH) parameters based on the BD limit and the CCE limit for monitoring for a combination downlink control information (DCI) that schedules at least one of data or reference signal (RS) transmissions in multiple cells, and monitoring for the combination DCI based on the determined PDCCH parameters.

A terminal includes a receiving unit that receives, through a first component carrier of a plurality of component carriers forming carrier aggregation, scheduling information for one or more second component carriers of the plurality of component carriers; and a control unit that configures rate matching on the one or more second component carriers, based on configuration information on the rate matching included in the scheduling information.

A wireless device receives one or more configuration parameters indicating a mapping pattern that indicates a cyclical mapping of spatial domain transmission filters to physical uplink shared channel (PUSCH) repetitions. The wireless device receives a downlink control information (DCI) scheduling repetitions of a PUSCH transmission, where the DCI comprises a frequency hopping field set to one and indicates a frequency offset. Based on the frequency hopping field being set to one and the mapping pattern indicating the cyclical mapping, the wireless device sequentially transmits, starting from a first resource block, a first repetition of the PUSCH transmission using a first spatial domain transmission filter and a second repetition using a second spatial domain transmission filter; and sequentially transmits, starting from a second resource block, a third repetition using the first spatial domain transmission filter and a fourth repetition using the second spatial domain transmission filter.

A method and apparatus for autonomous changing for dormant bandwidth part in a wireless communication system is provided. A wireless device configures a cell group including a certain cell on which a PUCCH is configured. A wireless device activates a dormant BWP of the certain cell to be an active BWP of the certain cell, wherein no PDCCH is configured on the dormant BWP. A wireless device switches the active BWP of the certain cell from the dormant BWP to another BWP upon triggering the scheduling request procedure, wherein at least one PDCCH is configured on the other BWP.
