Methods, systems, and devices for wireless communications are described. Wireless communications systems may support implementation of narrow bandwidth parts (NBWPs). For example, a NBWP may be established over a reduced bandwidth to support user equipment (UEs) with reduced complexity features (e.g., such as UEs with reduced bandwidth capabilities). Wireless communications systems may provide for UE transitioning to a NBWP (e.g., after initial cell search), as well as for UE transitioning amongst NBWPs (e.g., subsequent transitions to other NBWPs after an initial transition to a NBWP after initial cell search). For example, a UE may initially transition to a NBWP (e.g., transition to monitor the NBWP for reference signals or to utilize the NBWP for uplink/downlink communications) to support reduced bandwidth capabilities of the UE. Subsequently, the UE may transition amongst other NBWPs for network load balancing, UE frequency hopping gain, etc.

A method, wireless device and network node are disclosed. According to one aspect, a method for a wireless device includes receiving a configuration of a reference signal resource set from the network node, the reference signal resource set being a set of single-symbol and single antenna port reference signal resources in at least one slot; and based on at least one parameter of the received configuration, determining whether the UE can assume a same antenna port for all reference signal resources of the reference signal resource set.

A wireless communication method and device are provided. The method includes: a network device detecting, on the basis of M candidate time positions of a synchronous signal block, whether a carrier on an unlicensed frequency band is idle, the M candidate time positions being at least part of L candidate time positions of the synchronous signal block, the L candidate time positions being all the candidate time positions within a single transmission period of the synchronous signal block; according to a detection result, the network device sending the synchronous signal block at at least one of the M candidate time positions.

According to certain embodiments, a method performed by a wireless device for paging occasion (PO) allocation is provided. The method includes determining that a PO configured for the wireless device in a Discontinuous Reception (DRX) cycle is problematic. A non-problematic PO is selected based on one or more criteria. One or more paging messages are monitored for during the selected non-problematic PO.

Provided are a method for sending a signal channel, a base station, a storage medium, and an electronic apparatus. The method includes the following steps: a signal channel is configured, where the signal channel is used for cell search, synchronization and measurement; and the signal channel is sent to a terminal.

Various embodiments may provide systems and methods for managing transmit (TX) timing of data transmissions. The methods include applying a plurality of radio frequency (RF) channel factors related to data uplink transmissions by the wireless device to a TX timing model configured to provide as an output a TX timing for a data transmission to a base station and a number of carriers for sending the data transmission, and selecting a TX time and a number of carriers for sending a next data transmission to the base station based in part on the TX timing model output.

Provided are an access method and transmission point. In the embodiments of the present invention, indication information sent by a second transmission point is received by means of a first transmission point and is used for indicating that said second transmission point supports relay functionality, such that said first transmission point is capable of accessing, according to the indication information, the wireless access network on which the second transmission point is located; thus the first transmission point is taken as a relay node and accesses the wireless access network.

The present application provides a time synchronization method and an electronic device. The method includes sending a clock synchronization signal and first real time clock (RTC) information separately; and the clock synchronization signal is configured to measure a delay between a first module and at least one second module, the delay is used for phase compensation performed on the clock synchronization signal received at the side of the at least one second module, and the clock synchronization signal after being subjected to the phase compensation is configured to trigger the at least one second module to update local second RTC information to the first RTC information.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for operating a terminal in a wireless communication system, the method comprises determining a time-frequency structure of a downlink reference signal, and receiving, from a base station, the downlink reference signal according to the time-frequency structure.

A base station may transmit a control channel transmission during a configured discovery reference signal window on a shared spectrum. A user equipment (UE) may detect the control channel transmission from the base station during the configured discovery reference signal window on the shared spectrum. The UE may determine, in response to detecting the control channel transmission, expected synchronization signal block (SSB) positions within a maximum SSB burst length starting from the control channel transmission during the discovery reference signal window. The base station may transmit SSBs at the expected SSB positions within the maximum SSB burst length starting from the control channel transmission during the discovery reference signal window. The UE may measure SSBs at the expected SSB positions. The UE may conserve power by stopping measurements or entering a sleep mode after the expected SSB positions.
