Abstract: restrições a um sinal de referência de origem para referência de temporização de quase-colocalização de um sinal de referência de posicionamento. são divulgadas técnicas relacionadas às comunicações sem fio. em um aspecto, uma entidade de rede determina se um sinal de referência de origem transmitido de um primeiro ponto de transmissão-recepção (trp) é uma fonte de quase-colocalização (qcl) de um sinal de referência de destino transmitido de um segundo trp com base, pelo menos em parte, em uma primeira porção de largura de banda (bw) ocupada pelo sinal de referência de origem e uma segunda porção de bw ocupada pelo sinal de referência de destino, a primeira porção de bw tendo uma primeira frequência inicial e um primeiro tamanho de bw e a segunda porção de bw tendo uma segunda frequência inicial e um segundo tamanho de bw, e configura um equipamento de usuário (ue) com o sinal de referência de origem como a fonte de qcl do sinal de referência de destino quando assim determinado.

Abstract: A receiver may train its equalizer using consecutive pilot bursts, divide the traffic between the consecutive pilot bursts into multiple sub-segments, and interpolate the trained equalizer coefficients to obtain the coefficients for equalizing one or more of the sub-segments. The receiver may also determine signal to interference and noise ratio (SINR) values based on each of the consecutive pilot bursts, and interpolate the SINR for decoding one or more of the sub-segments. The receiver may be an access terminal receiver operating in a code division multiple access (CDMA) cellular system.

Abstract: A method for blindly determining positioning reference signals in a wireless communication network determines a positioning reference signal (PRS) network configuration by estimating a PRS energy from predetermined locations of each subframe of an incoming signal. Such a method may also include blindly detecting PRS parameters based on the estimated PRS energy. The PRS energy may be peak energy responses for deep searches or verifications. The PRS energy may be a signal to signal plus noise ratio for shallow searches.

Abstract translation: 用于在无线通信网络中盲定位确定定位参考信号的方法通过估计来自输入信号的每个子帧的预定位置的PRS能量来确定定位参考信号（PRS）网络配置。 这样的方法还可以包括基于估计的PRS能量盲检测PRS参数。 PRS能量可能是深度搜索或验证的峰值能量响应。 对于浅搜索，PRS能量可能是信号与信号加噪声比。
