A method and apparatus for performing communication in a wireless communication system are disclosed. In an embodiment of the present disclosure, a method for performing communication by a user equipment (UE) may include receiving, from a base station, configuration information related to at least one time domain resource allocation (TDRA) row including a plurality of start and length indicator values (SLIVs) for a physical downlink shared channel (PDSCH) and receiving, from the base station, first downlink control information (DCI), and the first DCI includes transmission configuration indicator (TCI) state indication information and does not include downlink (DL) assignment information, and a number of SLIVs in a specific TDRA row indicated by the first DCI among the at least one TDRA row is 1.

An object is to provide alternative communication means that does not require establishment of a connection. A communication control device according to the present technology includes: a first communication unit that performs communication by a device designation method that performs signal communication while designating a communication target device; a second communication unit that performs communication by a broadcasting method that performs signal communication without designating the communication target device; and a switching control unit that, when the first communication unit is performing communication with the communication target device, switches a communication system from the device designation method by the first communication unit to the broadcasting method by the second communication unit in accordance with a communication condition of the first communication unit such that the communication with the communication target device is continuously performed by the second communication unit.

A terminal includes a controller configured to identify a resource that is included in a time domain in which a first channel used for transmitting a response related to retransmission control is allocated, and that is included in a frequency domain that is not used for transmitting the first channel; and a transmitter configured to transmit a second channel or a signal by using the resource.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine downlink (DL) channel state information; and transmit a first sounding reference signal (SRS) and a second SRS, wherein the second SRS is precoded based at least in part on the DL channel state information. Numerous other aspects are provided.

A communication method and an apparatus includes a network device sends first information to a terminal device, so that the terminal device can determine a HARQ feedback manner based on the first information, where the HARQ feedback manner includes skipping ACK feedback and/or NACK feedback. In this manner, the network device controls the HARQ feedback manner used by the terminal device, so that the terminal device can be flexibly controlled to use different HARQ feedback manners in different scenarios, to adapt to a service constraint, effectively reduce power consumption of the terminal device, and save air interface resources.

A transmission or reception configuration method includes: executing, according to first transmission or reception configuration information, a target behavior in a time resource configured by the first transmission or reception configuration information. The first transmission or reception configuration information is at least one set of transmission or reception configuration information in N sets of transmission or reception configuration information.

This application provides a communication method and apparatus. One example method includes, obtaining, by a terminal device, a first frequency domain resource and a second frequency domain resource, wherein the first frequency domain resource and the second frequency domain resource are independently configured, and the second frequency domain resource comprises a control-resource set (CORESET) 0 and an initial bandwidth part (BWP); and receiving, by the terminal device, first information, wherein the first information is used to schedule a downlink data channel, the first information comprises frequency domain resource assignment information, wherein the frequency domain resource assignment information indicates a frequency domain resource of the downlink data channel within a range of the first frequency domain resource, and the first information is scrambled by using a group-radio network temporary identifier (G-RNTI) this application.

A communication management system (such as hardware and/or executed software) receives performance information indicating wireless connectivity performance between a communication device and a set of candidate wireless access points. The communication device is initially in communication with a first wireless access point over a wireless link. Based on the performance information, the communication management system selects a candidate wireless access point from the set in which to performance a handoff. The communication management hardware the notifies the communication device to handoff the wireless link from the first wireless access point to the selected candidate wireless access point.

A Multicast-Broadcast over a Single Frequency Network (MBSFN) message may be multicasted to a cluster of network elements. Using multicasting or unicasting based on a number of unacknowledged network elements of the cluster of network elements, the MBSFN message may be retransmitted to unacknowledged network elements in the cluster of network elements, subsequent to a time period to receive an acknowledgement message from a first and a second network element.

Methods and apparatuses are provided for determining a resource for an acknowledgement signal in a wireless communication system. A transceiver of a user equipment (UE) receives a parameter associated with one or more resource blocks (RBs) for periodic transmission of a channel quality indication (CQI) signal in an operating bandwidth. A controller of the UE determines an RB for transmission of the acknowledgement signal, based on the parameter. The transceiver transmits the acknowledgement signal on the determined RB. The RB for the transmission of the acknowledgement signal is not more outer than the one or more RBs for periodic transmission of the CQI signal in the operating bandwidth.
