This application provides a signal sending method, a signal receiving method, and an apparatus. The method includes: receiving, by a terminal device on a first carrier, a narrowband primary synchronization signal (NPSS) sent by a network device according to a first period and a narrowband secondary synchronization signal (NSSS) sent by the network device according to a second period; receiving, by the terminal device on a second carrier, a narrowband physical broadcast channel (NPBCH) sent by the network device according to a third period and a system information block 1-narrowband (SIB1-NB) sent by the network device according to a fourth period; and completing, by the terminal device, downlink synchronization and obtaining system information based on the NPSS, the NSSS, the NPBCH, and the SIB1-NB.

An information transmission method, an information transmission apparatus, an electronic device, and a readable storage medium. The information transmission method includes: determining, by a first centralized unit, resource configuration coordination information; and sending, by the first centralized unit, a first message carrying the resource configuration coordination information to a second centralized unit.

A wireless device receives an identifier of a communication service provider. The wireless device determines to establish a PDU session for a network slice associated with a service of the communication service provider. The wireless device sends to a session management function a first message requesting establishment of the PDU session, the first message comprises a single network slice selection assistance information of the network slice and an identifier of the communication service provider. The wireless device receives from the SMF a second message accepting the establishment of the PDU session.

A base station is partitioned into a part executed on at least one virtualization platform and a plurality of Radio Transceiver Points (R-TPs).

It is established at least one CCord (Central Controller or Central Coordinator) of the base station, internal or external to the at least one virtualization platform, connected with the at least one virtualized part of the base station and to the plurality of R-TPs by at least one control logical interface.

Communications with the User Equipment (UE) implement a protocol split: on each R-TP, at least MAC (Medium Access Control) functions and at least a part of PHY (Physical Layer) functions and on the virtualization platform at least PDCP (Packed Data Convergence Protocol) functions. CCord collects reports from each R-TP, with respect to resource status, and based on the collected reports selects at least one new serving R-TP of the at least one UE.

A method and apparatus are provided for updating a sequence hopping (SH) pattern of an uplink channel during handover from a current cell having a current SH pattern. A method may include receiving, from a base station associated with current cell, a transmission including information indicating a handover command that instructs the WTRU to handover to a target cell. The handover command may include information indicating a SH enablement indication and a SH parameter. The SH enablement indication may indicate that SH is enabled for a physical uplink control channel (PUCCH) transmission. A PUCCH transmission may be sent to a base station associated with the target cell, and the PUCCH transmission may include symbols derived from a sequence that is based on the SH parameter.

The described technology is generally directed towards network slice pre-configuration for cellular communication systems, including 5G and subsequent generation cellular communication systems. Network equipment can be preconfigured to identify whether a network slice identifier included in a network communication belongs to a group of network slice identifiers. If so, the network equipment can process the network communication either according to a network slice rule that corresponds specifically to the network slice identifier, or according to a default group network slice rule for the group to which the network slice identifier belongs. Different groups of network slice identifiers can be associated with different sets of group network slice rules which can be arranged to reduce the work of setting up network slice identifiers in various network slicing scenarios.
