Título: (EN) Signaling resource allocation method for uplink reference signal
(ZH) 上行参考信号的信令资源分配方法
Resumo: front page image
(EN) The invention discloses a signaling resource allocation method for an uplink reference signal, which comprises the following steps that: when a single user transmits a user rank (Rank is equal to 1 or 2), or a plurality of users transmit the user rank (Rank is equal to 1 or 2) with uniform bandwidth allocation, signaling only uses a cyclic shift CS, but not an orthogonal mask code OCC; and when the plurality of users transmit the user rank (Rank is equal to 1 or 2) with nonunifrom bandwidth allocation or transmit the user rank (Rank is equal to 3 or 4) with uniform bandwidth allocation, or the single user transmits the user rank (Rank is equal to 3 or 4), the signaling uses the cyclic shift CS and the orthogonal mask code OCC. The signaling resource allocation method for the uplink reference signal provides an implicit signaling distribution way aiming at introducing the OCC into an LTE-A system reference signal sequence in an uplink situation. By using the technical scheme of the invention, on the premise of ensuring that extra signaling bits are not added, the signaling resource of the uplink reference signal of the user is allocated fully and flexibly, and the system performance is improved.

本发明揭示了一种上行参考信号的信令资源分配方法,当单用户传输、用户的秩Rank=1或2,或者多用户传输等带宽分配、用户的秩Rank=1或2时,信令只使用循环移位CS,不使用正交掩码OCC;当多用户传输非等带宽分配,或者多用户传输等带宽分配、用户的秩Rank=3或4,或者单用户传输用户的秩Rank=3或4时,信令使用循环移位CS及正交掩码OCC。本发明提出的上行参考信号的信令资源分配方法,在上行场景中,针对LTE-A系统参考信号序列中OCC的引入,提供了一种隐式信令分配方式。采用本发明的技术方案,可以保证在不增加额外信令比特的前提下,比较充分且灵活的分配上行各用户的参考信号信令资源,并提高系统性能。
