Methods and apparatuses in a wireless communication system. A method of operating a user equipment (UE) includes storing a previous layer 3 (L3) filtered measurement result; receiving L3 filtering configuration information including a first filter coefficient value (k) and a first filtering window value; identifying a generation time instance of the previous L3 filtered measurement result; identifying the first filter coefficient value (k) and the first filtering window value included in the L3 filtering configuration information; in response to receiving a latest measurement result from a lower layer, determining whether the generation time instance of the previous L3 filtered measurement result was obtained within a time window that is a function of a first time instance and a second time instance; and performing an L3 filtering operation to trigger a measurement report based on a result of the determination.

A method for activating a TCI state includes: receiving a first MAC CE signaling, the first MAC CE signaling for activating a first TCI state; and using the first TCI state as TCI states of all serving cells on the same frequency band.

Systems and methods are disclosed herein that relate to frequency domain resource allocation for interlaced transmission. Embodiments of a method performed by a wireless device are disclosed. In one embodiment, a method performed by a wireless device comprises receiving a reserved resource indicator that indicates an uplink reserved resource pattern. The uplink reserved resource pattern defines at least which subset of uplink Physical Resource Blocks (PRBs) from among a set of allocated uplink PRBs are not available for uplink transmission. In this manner, a low overhead, flexible frequency domain resource allocation scheme for partial interlace transmission is provided.

Provided is a method of performing communication by using a plurality of Radio Link Control (RLC) entities in a wireless communication system, the method including: receiving a packet duplication configuration for a radio bearer from a base station (BS) via a Radio Resource Control (RRC) message; configuring a plurality of RLC entities including one primary RLC entity and one or more secondary RLC entities which correspond to a preset Packet Data Convergence Protocol (PDCP) entity, based on the packet duplication configuration; and receiving a Medium Access Control Control Element (MAC CE) for controlling activation or deactivation of the one or more secondary RLC entities from among the plurality of configured RLC entities.

Methods and devices for discontinuous reception signaling for wireless communications systems are described. A base station may determine a semi-persistent scheduling (SPS) configuration and a discontinuous reception configuration (DRX) associated with the semi-persistent scheduling (SPS) configuration for a user equipment (UE). The base station may transmit the SPS configuration to the UE. The SPS configuration may indicate one or more DRX parameters for the DRX configuration. A UE may receive the semi-persistent scheduling configuration from the base station. The UE may identify one or more DRX parameters for the discontinuous reception configuration based on the SPS configuration. The UE may monitor a downlink control channel in accordance with the DRX configuration.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to the present disclosure, a priority relative to data is configured by assigning a priority a MAC CE so that a MAC PDU may be transmitted according to the priority.

Techniques of ensuring that the survival time requirement is fulfilled include applying, by the UE (transmitter), a plurality of different logical channel (LCH) mapping restrictions to the packets on the same data radio bearer (DRB). In some implementations, the LCH mapping restrictions to be applied depend on the SN of the PDCP PDU to be processed. For example, the first LCH mapping restriction may be limited to radio resource with lower reliability (e.g., with the first LCH mapping restriction, the data from this LCH can only be mapped to a CG configuration without repetition and/or high MCS), while the second LCH mapping restriction may be limited to radio resources with extremely high reliability (e.g., with the first LCH mapping restriction, the data from this LCH can only be mapped to a CG configuration with repetitions and/or low MCS).

In a wireless local area network (WLAN) system, a transmission station (STA) may transmit a PPDU including a first data field and a second data field to a reception STA, and the second data field may be generated by duplicating the first data field. The PPDU may include information indicating that the first data and the second data are the same data.

Provided are a communication mode switching method, and an apparatus and a device. The method includes sending a Packet Data Convergence Protocol (PDCP) data transmission status of user equipment in a first communication mode to a second network device, wherein the second network device is configured to use a second communication mode to deliver a service to the user equipment according to the PDCP data transmission status.

A data transmission method and related devices are provided. The method includes the following. A terminal receives a control message transmitted by a network device, where the control message indicates to activate or deactivate a packet data convergence protocol (PDCP) duplication corresponding to a data radio bearer (DRB) and/or indicates a PDCP-duplication activation status corresponding to the DRB, and the DRB is a first DRB or a second DRB. The terminal activates or deactivates the PDCP duplication corresponding to the DRB according to the control message.
