摘要： In a capacity region of a multiple access channel which is a theoretical limit, a combination of transmission speeds that are equal between the channels is realized. A wireless communication apparatus receives first to third frames, which are sequentially transmitted. The second frame is transmitted at a head time different from that of the first and third frames, and the second frame receives a first signal which is temporally superposed to both the first and third frames. A replica signal of the first frame is generated based on the result obtained by demodulating the first frame, and a second signal which is obtained by canceling it from the first signal is generated. The second frame is demodulated by using the second signal, and the interference from the first frame in the second frame in the second signal is canceled, and the interference from the third frame remains.

摘要： Techniques for transmitting and detecting for overhead channels and signals in a wireless network are described. In an aspect, a base station may blank (i.e., not transmit) at least one overhead transmission on certain resources in order to detect for the at least one overhead transmission of another base station. In one design, the base station may (i) send the overhead transmission(s) on a first subset of designated resources and (ii) blank the overhead transmission(s) on a second subset of the designated resources. The designated resources may be resources on which the overhead transmission(s) are sent by macro base stations. The base station may detect for the overhead transmission(s) from at least one other base station on the second subset of the designated resources. In another aspect, the base station may transmit the overhead transmission(s) on additional resources different from the designated resources.

摘要： Systems and methods are provided for determining a successive interference cancellation (SIC) decoding ordering in a multiple input multiple output transmission (MIMO) system. Multiple decoding orderings for received codewords are identified. A performance objective, such as total throughput or total probability of decoding, is computed for each one of the orderings based on the position of the codewords in the ordering. A globally optimal ordering is found that maximizes the performance objective over the multiple decoding orderings.

摘要： Devices and methods for scheduling and interference cancellation that consider the interference cancellation capability of user equipment (UEs) are disclosed. Using reduced-rate sub-frame (or resource block) strategies, the transmission data rate to a scheduled user in a given cell may be reduced to ensure effective interference cancellation performance at the receiver of a co-scheduled user in another cell. By taking advantage of interference mitigation at one or more terminals, a scheduler may improve network spectral efficiency compared to existing inter-cell interference cancellation schemes, including almost blank sub-frame (ABS), further enhanced inter-cell interference coordination (FeICIC), and other resource partitioning schemes, such as reduced power sub-frames or frequency domain resource partitioning.

摘要： A first user equipment UE operating in a first/strong transmission mode determines that a second UE is operating in a second/weak mode and is allocated a same radio resource as the first UE. The first UE determines a transport format for transmissions to the second UE and uses that to decode and cancel a transmission received on the radio resource which is directed to the second UE, mitigating interference with a further transmission directed to the first UE. Various examples are given of specific resource allocation signaling used to determine that the second UE is operating in the second mode and is allocated the same radio resource, such as implicitly by a specific downlink control indication format or an explicit indication in a resource allocation directed to the first UE. The first UE can determine the transport format of the second UE from network signaling.

摘要： A first network node (111) and a method therein for controlling load in a first cell (121) of the first network node (111) are provided. The first network node (111) comprises a multi-stage receiver. The first network node (111) computes an interference cancellation gain, at an intermediate stage of the multi-stage receiver. Furthermore, the first network node (111) estimates neighbour cell interference from interfering signals while accounting for a load utilization. The load utilization relates to power transmitted and power granted. The first network node (111) calculates a load measure for stability based on at least the interference cancellation gain and the neighbour cell interference. Next, the first network node (111) controls the load in the first cell (121) based on the load measure for stability.
