20120207102 | Prioritizing RACH Message Contents - A network/base station broadcasts an indication to direct a user equipment how to prioritize information for inclusion in an uplink message to be sent on a random access channel RACH. By example one value of the indication directs a user equipment UE to prioritize inter-frequency over intra-frequency neighbor cell measurements for inclusion in the uplink message; and another value (or absence) of the indication directs a UE to prioritize intra-frequency over inter-frequency neighbor cell measurements for inclusion in the uplink message. A UE receiving the broadcast indication constructs the uplink message which includes information that is prioritized in accordance with the indication so as not to exceed a maximum message size. There are also embodiments with second and/or further/third indications in the broadcast system information for more efficiently utilizing the available space in the RACH message, which by example is an RRC Connection Request message in which UE capability information may be prioritized higher or lower than the measurement information. | 2012-08-16 |
20120207103 | Method and System for Transmitting Downlink Control Information - The present invention discloses a method and a system for transmitting downlink control information, wherein when a base station is not configured with a carrier indicator field, the base station transmits a physical downlink control channel bearing the corresponding downlink control information on each downlink component carrier in a user equipment's physical downlink shared channel (PDSCH) carrier set, and the user equipment detects the corresponding downlink control information on each downlink component carrier in the configured PDSCH carrier set. When a base station is configured with a carrier indicator field, the base station transmits the physical downlink control channel bearing the corresponding downlink control information on each downlink component carrier in the configured physical downlink control channel (PDCCH) carrier set, and the user equipment detects the corresponding downlink control information on each downlink component carrier in the PDCCH carrier set. | 2012-08-16 |
