摘要： A chip rate invariant detector (FIG. 2) is used in a wireless spread spectrum high capacity communications system which can accommodate two or more different chip rates. At a higher chip rate the data blocks are segmented into uniform suitable sizes for the detector which has an increased data block length to prevent loss of information to smearing due to effective overlap of segmented data blocks. The resultant data blocks are cut down to standard size by discarding samples and applied to a matched filter for further standard information processing.

摘要： Paging group identifiers are associated with groups of user equipment (UEs) in a hierarchical manner. A controller, such as a scheduler in an enhanced Node B, may address the groups of UEs using group identifiers over control channels. The controller may select a group identifier for a group of UEs from higher or lower levels of the hierarchy, depending upon the number of UEs to be paged and/or the number of available control channels over which paging resources are dynamically allocated to the UEs. UEs within the addressed groups monitor the corresponding paging channels for paging messages.

摘要： A method of requesting a communication resource by a wireless communication unit operating in a wireless communication system. The wireless communication system provides for uplink and downlink channels. The method includes the steps of: allocating a dedicated communication channel to said wireless communication unit by a wireless communication serving unit; transmitting a communication resource request message (130) on said dedicated uplink channel by said wireless communication unit (110) to said wireless communication serving unit (120); and transmitting an access allocation message (140) to said wireless communication unit (110) from said wireless communication serving unit (120) on said dedicated downlink channel. A communication system and communication unit are also provided.This provides the advantage that a dedicated channel is used for requesting shared resources thereby avoiding various problems, including clashes, associated with using a random access channel.
