摘要:
A method and system for achieving timeframe alignment between a Centralized Base Station Controller (CBSC) (106) and a Base Transceiver Site (BTS) (102) in a network is disclosed. The BTS returns a Forward Sequence Number (FSN) contained in a forward frame and a Packet Arrival Time Error (PATE) to the CBSC. The CBSC computes a Round Trip Time (RTT), using the FSN. The CBSC also computes a forward Coordinated Universal Time (UTC), using the RTT and the PATE. Thereafter, a CBSC transmission time is adjusted to align with the BTS, based on the adjusted UTC.
摘要:
A mobile unit 40 which is in a soft handoff condition 50 with a base station (32) has the power transmitted by the base station (32) on the mobile link (52) controlled. The base station (32) determines (70) when a frame erasure count reaches a particular level N. The base station then places this link in a clamped state (72) at minimum power. When the base station determines that M consecutive good frames have been received (92), the base station restores the link (52) to a normal state (94). A recovery arrangement (100, 110 and 120) prevents clamping by all base stations (32-34) and loss of the link.
摘要:
Technology to process radio link control (RLC) groups is disclosed. In an example, a carrier aggregation (CA) capable user equipment (UE) operable process radio link control (RLC) groups can include a UE radio frequency (RF) transceiver and a processor. The UE RF transceiver can be configured to receive packets from more than one cell via a sending node RF transceiver. The processor can be configured to process service data units (SDU) of the packets in a radio link control (RLC) entity of a protocol stack (PS). Each SDU can be associated with an RLC flow identifier (RFI). The RFI can comprise an RLC group identifier (RGI) indicating the sending node RF transceiver, and a radio bearer identifier (RBID).
