example 1
[0170] Example 1: Each level sequence needs to carry the level indication information of the multi-level sequence. Taking the two-level sequence in this embodiment as an example, the initial phase of the first-level gold sequence needs to contain 1-bit level index information, such as bit 0, the first level The initial phase of the two-level gold sequence also includes 1-bit initial phase information, such as bit 1. If there are more-level sequences, the number of bits indicating the level index will naturally increase. For example: the maximum number of information bits carried by energy saving (power saving) information is InforNum=24, and the initial phase of the first level (gold) sequence can carry wake up area ID related information (accounting for 10 bits) and wake up ID related information (accounting for 8 bits) bits), the stage index information of the first-level sequence (accounting for 1 bit); the initial phase of the second-level gold sequence can carry wake up ar...
example 2
[0171] Example 2: The subsequent level (gold) sequence needs to carry the level indication information (for example: group index information) carried by the previous level or multi-level (gold) sequence. For example, taking the two-level sequence as an example, the first level gold sequence contains Each specific sequence carries information related to a specific wake up ID. If all possible sequences of the first-level sequence are regarded as a set of sequences, the set of sequences can be grouped to obtain S subgroups. index can be used as a group index information. The second-level gold sequence needs to carry the middle and group index information of the first-level sequence, and the information may be a function of the initial phase of the second-level gold sequence. Since the first-level sequence is grouped, the subgroup index is passed to the second-level sequence. The minimum S value of the subgroup number can be 1, and the maximum S value can be as many as the number ...
Embodiment 1
[0229] An example of power saving signal based on multi-level sequence image 3 As shown, in order to describe a simple period, it is assumed to be a power saving signal composed of a two-level sequence. The first-level sequence generation method is as follows: base station side frequency domain sequence: sequence 1, sequence 2, sequence 3, ... sequence M1 are accumulated, and then IFFT and adding CP operations are performed on the sum sequence and mapped to m1 OFDM symbols in the time domain to obtain The first-level sequence; the second-level sequence generation method is similar to the first-level generation method, frequency domain sequence M1+1, sequence M1+2, sequence M1+3, ... sequence M are accumulated, and then IFFT is performed on the sum sequence and add CP operation to map the m-m1 OFDM symbols in the time domain to obtain a second-level sequence, and the two-level sequences together constitute a power saving signal. The minimum value of the OFDM symbol index in t...
