Publication number: 20190363818Abstract: A method for allocating and processing sequences in a communication system includes: dividing sequences in a sequence group into multiple sub-groups, each sub-group corresponding to its own mode of occupying time frequency resources; selecting sequences from a candidate sequence collection corresponding to each sub-group to form the sequences in the sub-group by: the sequences in a sub-group i in a sequence group k being composed of n sequences in the candidate sequence collection, the n sequences making a |ri/Ni?ck/Np1| or |(ri/Ni?ck/Np1) modu mk,i| function value the smallest, second smallest, till the nth smallest respectively; allocating the sequence group to cells, users or channels. It prevents the sequences highly correlated with the sequences of a specific length from appearing in other sequence groups.Type: ApplicationFiled: June 10, 2019Publication date: November 28, 2019Applicant: Huawei Technologies Co., Ltd.Inventors: Bingyu QU, Yujuan HE, Xuan FENG

Publication number: 20150327221Abstract: A method of signaling is disclosed. A terminal receives downlink control signaling from a base station and sends an uplink packet to the base station. The uplink packet is sent according to the received downlink control signaling. The downlink control signaling includes a field that includes N bits. The field itself is dynamically indicative of one of a payload size or a redundancy version such that the field itself is indicative of the payload size if a packet that the terminal will send to a base station is an initial transmission and the field itself is indicative of the redundancy version if the packet that the terminal will send to the base station is a retransmission.Type: ApplicationFiled: May 15, 2015Publication date: November 12, 2015Inventors: Xianghua Wang, Xuan Feng
