Method of controlling aggregate searching dispatching of CDMA communication

Abstract

The present invention relates to a method for the search scheduling of a control set for CDMA communication. The search scheduling depends on the search time of the control channels in the set, the number of control channels in the set and the strength of these channels. A given control channel is usually at several received at time offsets, each offset is associated with a control channel multipath, for each control channel search its range should be a PN offset range (search window), in which all multipaths found in the window The energy is added to form the energy measure of the control channel. The network provides the size of the search window in the system parameter information. SRCH_WIN_A defines the window width of the active set and the candidate set, and SRCH_WIN_N defines the window width of the neighbor set.

Description

Technical field:

[0001] The invention relates to a control set search scheduling method for CDMA communication, which belongs to the field of mobile communication manufacturing. Background technique:

[0002] In the CDMA 1 and CDMA2000 standards, each base station continuously sends non-data-modulated direct-sequence signals in the control channel. This signal is composed of a data block stream (CHIP), and the maximum length of each data block is a PN (pseudo-noise) sequence (the period of each sequence is 2 15 ), the control channel is identified by a length interval of 64 data blocks compared with the 0 offset control (PN) sequence. In addition to providing a reference phase for coherent demodulation, the control signal can also enable the mobile station (terminal) to obtain and maintain the previous To the timing of the data link, and to judge the strength of the base station signal to switch in a timely manner.

[0003] In the above-mentioned CDMA standard, soft / hard h...
