  • Patent number: 9020060
    Abstract: The present invention provides a virtual multiple-input multiple-output communication method and device. The method includes: determining a user set to which a user equipment in a sector belongs, where the user set includes a first user set and a second user set, a user equipment in the first user set is in a beam coverage area of a first antenna group in the sector but is not in a beam coverage area of a second antenna group of the sector, and a user equipment in the second user set is in the beam coverage area of the second antenna group but is not in the beam coverage area of the first antenna group (101); and selecting, when a scheduled user equipment belongs to the first user set, an unscheduled user equipment in the second user set for pairing.

  • Publication number: 20150036628
    Abstract: Embodiments of the present invention provide a method and an apparatus for determining a coordinated multi-point transmission/reception CoMP coordination set, which can increase an interference suppression gain during CoMP. The method includes: receiving, by a first cell, CoMP resource block information of a second cell sent by the second cell, where the CoMP resource block information of the second cell indicates a CoMP resource block of the second cell; obtaining, by the first cell, a CoMP coordination set of each CoMP resource block of the first cell according to CoMP resource blocks of the first cell and the CoMP resource blocks of the second cell; and determining, by the first cell, that a union set of CoMP coordination sets of all the CoMP resource blocks of the first cell is a CoMP coordination set of the first cell.

  • Publication number: 20140086148
    Abstract: Embodiments of the present invention disclose a method and a base station for coordinating cell interference. The method includes: receiving each backhaul signal transmitted by each cooperative base station, where the backhaul signal is determined by the cooperative base station according to strength of a signal received from a served user and strength of a signal received by a serving base station from an interfering user in the cooperative base station; and combining, at different stages of baseband processing and according to a type of each backhaul signal, a backhaul signal of a corresponding type and a user signal received from each user. An embodiment of the present invention further provides a base station. According to the embodiments of the present invention, backhaul transmission capacity is maximally utilized, backhaul transmission efficiency is improved, and relatively high performance is obtained.

  • Publication number: 20140087784
    Abstract: A method, a device, and a system for coordinated multi-point transmission/reception are provided. The method includes: obtaining a reference signal received power RSRP of cells in a measurement set of a user equipment UE; determining a coordinated set of the UE according to the RSRPs; obtaining a post-processing SINR of the UE in the coordinated set and a post-processing SINR of the UE in a serving cell; determining that the post-processing SINR of the UE in the coordinated set is greater than the post-processing SINR in the serving cell; and performing coordinated multi-point transmission/reception for the UE. According to the method, the device, and the system provided by the embodiments of the present invention, an impact of an interference suppression gain on CoMP can be suppressed effectively, and the solution complexity can be reduced.

  • Publication number: 20140066081
    Abstract: Embodiments of the present invention provide a coordinated multipoint reception processing method and apparatus, and a base station. The method includes: performing demodulating and decoding an uplink signal received by k collaboration sets of M collaboration sets, to obtain k cyclic redundancy check CRC results, where the uplink signal is sent by a user equipment UE, the collaboration set is a serving sector where the UE is located or a set formed by the serving sector and any one or more collaborative sectors, M?2, and 1?k?M; and if the k CRC results include at least one correct CRC result, performing processing on a signal obtained by a CRC result of the at least one correct CRC result. According to the embodiments of the present invention, in a base station, detection performance is improved under actual channel estimation.
