Shared spectrum access for broadcast and bi-directional, packet-switched communications
摘要
說明書
In some embodiments, a cellular network is configured to schedule system information such as SIB2 such that it appears early in the DRX Active Time period, in order to allow UEs to quickly acquire SIB2. This may allow UEs to connect within the interval between broadcast frames, for example. Note, in the EUTRA example however, that a UE may first need to acquire the MIB and then SIB1 before acquiring SIB2, so system information scheduling should take this into account to ensure that UEs have sufficient time to acquire those three information blocks sequentially within the same DRX Active Time period.
In some embodiments, the network is configured to set the system information modification period to a large value (e.g., by configuring larger values for modificationPeriodCoeff and defaultPagingCycle (see the RadioResourceConfigCommon information element in Section 6.3.2 of 36.331)) to increase the amount of time over which acquired system information can be considered to remain valid.
In some embodiments, a UE may acquire the system information of the time-division multiplexed EUTRA carrier during one DRX Active Time period before initiating a connection to the EUTRA base station in the next DRX Active Time period, depending upon the actual time length of the DRX Active Time period.
