Measurement clearance information and use
For inter-frequency measurement, WTRU need carry out traditional FDD and measure.For the RAT measurements of GSM, WTRU for following any or a plurality of purpose as in UMTS, using measurement clearance:
-received signal strength indicator (RSSI) is measured;
-Base transceiver Station Identity Code (BSIC) identification; And
-BSIC heavily confirms.
In LTE, some particular cases, WTRU can be carried out full rate scanning from motion tracking GSM sub-district.
For the RAT measurements of Wideband Code Division Multiple Access (WCDMA) (WCDMA), if WTRU receives UMTS absolute radio frequency channel number (UARFCN) and corresponding Primary Synchronisation Code (PSG) in its adjacent cell list, WTRU will carry out PSC simply and heavily confirm.
For Wideband Code Division Multiple Access (WCDMA) (WCDMA) RAT measurements, if WTRU receives UMTS absolute radio frequency channel number (UARFCN) and do not have corresponding Primary Synchronisation Code in its adjacent cell list, WTRU uses measurement clearance to carry out following three steps:
-carry out synchronously with primary synchronization channel (P-SCH);
-carry out synchronously with secondary synchronization channel (S-SCH);
-from the motion tracking scrambler.
After the sub-district was identified and measures, network was measured the existence of confirming PSC of attaching most importance to by execution on PSC the gap is provided.By using suitable measurement purpose such as PSC heavily to confirm to indicate to WTRU.
Still in LTE, some particular cases, WTRU also may be carried out full rate scanning from motion tracking UMTS sub-district.In this case, the measurement clearance purpose may be following any one or a plurality of:
FDD measures;
Rssi measurement;
BSIC identification;
BSIC heavily confirms;
P-SCH is synchronous;
S-SCH is synchronous;
PSC identification;
PSC heavily confirms;
The scanning of GSM full rate;
The scanning of UMTS full rate;
Time division duplex (TDD)-3.84Mcps; And
·TDD—1.28Mcps。
If network sends absolute radio frequency channel number (ARFCN) and UARFCN with signal, latter two option above then not needing.
Optionally, if PSC is sent with signal in adjacent cell list, perhaps network configuration WTRU is single measurement purpose, to detect and to measure the UMTS sub-district in a gap, configuration WTRU uses another gap to confirm heavily whether PSC exists, and the measurement clearance purpose can be as follows so:
FDD measures;
Rssi measurement;
BSIC identification;
BSIC heavily confirms;
PSC detects
PSC heavily confirms;
The scanning of GSM full rate;
The scanning of UMTS full rate;
TDD-3.84Mcps; And
·TDD—1.28Mcps。
If network sends ARFCN and UARFCN with signal, latter two full rate Scanning Options above then not needing.
Optionally, network can use bitmap to come to send specific measurement purpose with signal.
The behavior of WTRU (behavior) in the particular measurement clearance mode
Provided the behavior of WTRU in the example of some measurement clearance patterns below.
If a plurality of measurement clearance are arranged, if being signaled before finish in gap 1, gap 2 begins to send, then the behavior of WTRU is not defined, if perhaps gap 2 has surpassed the measurement clearance modal length, then the behavior of WTRU is not defined (the perhaps such measurement configuration of WTRU refusal) yet.
If the measurement clearance pattern that takes place to attempt activating identical measurement purpose is as the measurement clearance pattern (MGMP) that is in state of activation, the behavior of WTRU is not defined (the perhaps such measurement configuration of WTRU refusal) so.
If in same sub-district, measurement clearance sends to WTRU more than once, (as once in setting up message, afterwards in switching message), if and two measurement clearance have identical sequence identifier, (being measurement clearance mode sequences identifier (MGPSI)), WTRU uses the last measurement clearance parameter group so, and previous group of the measurement clearance parameter is capped.
If in switching timing information kept and in switching command not the information about the measurement clearance parameter be sent out, the interim deexcitation measurement clearance of WTRU is then suitably calculated in new sub-district or reactivation measurement clearance during indication subframe sequence number.In between frequency, switching, when WTRU enters new sub-district,, need send it to WTRU if adjacent cell list is arranged.If WTRU when entering new sub-district, does not receive adjacent cell list, WTRU is with regard to the measurement configuration of use storage itself.
If the information of in switching, not holding time and in switching command not the information about the measurement clearance parameter be sent out, the interim deexcitation measurement clearance of WTRU then, in new sub-district, calculate the explicit active information that subframe sequence number reactivation measurement clearance or wait come automatic network rightly, with beginning measurement clearance in new sub-district with subframe sequence number.In this case, between frequency, switching, when WTRU enters new sub-district,, need send it to WTRU if adjacent cell list is arranged.If WTRU when entering new sub-district, does not receive adjacent cell list, WTRU is with regard to the measurement configuration of use storage itself.
In switching, if send any configuration or activation parameter in the duration in already present measurement clearance in the switching command, WTRU continue to use old measurement clearance parameter in the new sub-district, unless they in old sub-district by deexcitation.Replacedly, WTRU suppresses measurement clearance temporarily, indication or reactivation measurement clearance when calculating the subframe sequence number rightly in new sub-district.In between frequency, switching, when WTRU enters new sub-district,, need send it to WTRU if adjacent cell list is arranged.If WTRU when entering new sub-district, does not receive adjacent cell list, WTRU is with regard to the measurement configuration of use storage itself.
