Abstract: A first cell transmits a virtual cell identifier and state information associated with the virtual cell identifier over an interface to a second cell. The first cell and one or more third cells use the virtual cell identifier for transmissions to first user equipment. The state information indicates one of a plurality of states that indicate whether the virtual cell identifier is associated with at least one non-virtual reference signal for the first cell, the second cell, or one or more third cells. The second cell receives the virtual cell identifier and the state information and transmits the virtual cell identifier and state information over an air interface to second user equipment served by the second cell. The second user equipment performs interference cancellation or suppression of transmissions to the first user equipment based on the virtual cell identifier and the state information.

Abstract: Embodiments of the present disclosure provide a method for multiple input multiple output (MIMO) communications. For example, scheduling information is received at a terminal device from a network device, the scheduling information at least indicates physical resource blocks shared by a demodulation reference signal (DMRS) of the terminal device and a further DMRS of at least one further terminal device, and different sub-carriers allocated to the DMRS and the further DMRS in each of physical resource blocks, and the number of physical resource blocks is indivisible by a total number of the terminal device and the at least one further terminal device. The DMRS is generated, and a length of the DMRS is determined based on the number of physical resource blocks and the number of at least one further terminal device. The DMRS is transmitted to the network device on the sub-carriers allocated to the DMRS in the physical resource blocks. A corresponding method implemented at a network device such as a base station, and a terminal device and network device capable of implementing the above methods are also disclosed.

Abstract: A resource allocation method for network slicing and an orchestrator, comprising: uniformly incorporating resources originally bundled statically with the base station into a dynamic resource pool; allocating, by an orchestrator, resources from among the dynamic resource pool for the network slicing based on different network slicing requirements. A static corresponding/mapping relationship between the hardware/radio resources and the base station is broken, such that hardware/radio resources (e.g., radio access network Virtual Network Function (RAN VNF), baseband unit (BBU), RRH (Remote Radio Head) as well as antenna) that originally corresponded to different base stations will be organized as an integrated and dynamic hardware/radio resource pool and reported to the orchestrator, such that the orchestrator will centrally manage all hardware/radio resources in this pool and then sufficiently utilize and dynamically orchestrate these hardware/radio resources based different needs from the network slicing.

Abstract: The present disclosure provides a method and apparatus for X2 signaling. The method comprises, in a wireless communication network supporting coordinated multiple point transmission, transmitting load information from a first base station to at least one second base station via X2 signaling, wherein the load information comprises at least one item of i) a relative narrowband beam information element or ii) a relative narrowband scheduling information element. Current X2 signaling is enhanced to support coordinated multiple point transmission with non-ideal backhaul and improve interference coordination.

Abstract: Embodiments of the present disclosure provide a method and apparatus for indicating power allocation in multiuser superposition transmission. The method comprises: transmitting a signaling for indicating a first power parameter and a first power offset to a first UE so that the first UE determines first power allocation information specific to it based on the first power parameter and the first power offset; and transmitting a signaling for indicating a second power parameter and a second power offset to a second UE paired with the first UE so that the second UE determines second power allocation information specific to it based on the second power parameter and the second power offset. Embodiments of the present disclosure enable the near/victim UE of paired UEs to decode an interference signal caused by far/interfering UE based on power allocation information and remove the interference signal caused by far/interfering UE to improve correctness of decoding its own physical downlink shared channel data.

Abstract: The present invention relates to a method and an apparatus for controlling a rank information (RI) report. According to an embodiment of the present invention, a method for controlling an RI report of a User Equipment (UE) in a base station of a Long Term Evolution (LTE) mobile communications network is provided. The method includes the following steps: determining a Channel State Information (CSI) report set for a UE, where the CSI report set includes multiple CSI feedback modes (CSI processes); sending to the UE Radio Resource Control (RRC) signaling indicating the CSI report set; and sending to the UE signaling indicating a precoding codebook subset and/or rank restriction of each CSI feedback mode in the CSI report set. According to the above embodiment, rank selection and high rank transmission are supported for coordinated multi-point (CoMP) transmission in the LTE mobile communications network.

Abstract: The present invention is related to an apparatus and method for signaling information exchanging in CoMP (Coordinated Multi-Point). According to an embodiment of the present invention, in a method for signaling information exchanging, a service TP (Transmission Point) and at least one neighboring TP provide the CoMP to at least one UE (User Equipment). The method comprises receiving by the service TP a precoder feedback from at least one UE, wherein the precoder is specific to one of the least one neighboring TP. The service TP decides if the precoder should be sent to the specific neighboring TP. If affirmative, the service TP compresses an indicator indicating the precoder and sends the compressed indicator to the specific neighboring TP.
