    摘要: Transmission of certain channels between a User Equipment (UE) and a Node B (NB) in High Speed Packet Access (HSPA) of a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network may be scheduled during a UE's idle intervals. Scheduled transmissions during a UE's idle interval result in lost system resources because the transmissions do not occur. A NB may prevent conflicts between scheduled transmissions and a UE's idle period by prohibiting transfer of certain channels a predetermined number of radio frames before the UE's idle period. Alternatively, the NB may schedule transmission of certain channels with a predetermined delay to prevent the channels from being scheduled during the UE's idle period.

    摘要: Open loop power control in Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) multi-carrier systems is facilitated through the determination of a value for open loop control on a primary carrier frequency which is then used to perform open loop control on at least one secondary carrier frequency in the multi-carrier system. This determined open loop control value may be applied using the value determined on the primary carrier frequency, or may be further adjusted using an estimated difference between received power of the primary carrier frequency and the secondary carrier frequencies, in selected aspects. When the pilot signals in the secondary carrier frequencies are transmitted at different power levels, this open loop control value may be further adjusted with a transmit power level offset.

    摘要: Certain embodiments of the present disclosure provide an adaptive technique to determine size of a ranging back-off window according to a load of ranging channel. By applying an adaptive increase of the back-off window size, a probability of collision between ranging codes within a same transmission opportunity can be alleviated, and the ranging channel load can be decreased more efficiently than in the case of a standard non-adaptive back-off procedure.

    摘要: Post-hard handover processing in a Time Division—Synchronous Code Division Multiple Access (TD-SCDMA) network may be improved to allow operation of High Speed Packet Access (HSPA) in hard handover. For example, uplink synchronization may be completed concurrent with HSPA to quickly resume HSPA operation in hard handovers. User Equipment (UE) may receive downlink data while completing uplink synchronization. In another example, a unique SYNC_UL code may be assigned to a UE for hard handover. The unique SYNC_UL code allows Node Bs of the TD-SCDMA network to know which UE is performing hard handover. When a Node B is receiving the unique SYNC_UL, the Node B may begin to allocate UL data grants. After receiving UL data from the UE, the Node B may resume High Speed Downlink Packet Access (HSDPA).

    摘要: Wireless communication in a radio access network may be implemented where a user equipment (UE) sends a hold signal to a Node B indicating that data transmission to the UE is to be put on hold. The UE may resume data transmission from the Node B by sending a resume signal to the Node B. During the hold in transmission, the UE may measure a GSM network to assist in handover of the UE between a TD-SCDMA network and a GSM network.

    摘要: Wireless communication in a multicarrier radio access network may be implemented where a user equipment (UE) maintains communication with various carrier frequencies in the multicarrier network. The UE will receive an indication from a node B to measure a signal quality on one of a number of carrier frequencies in the network. The UE will then measure the signal quality on the carrier frequency based on measurements using a downlink synchronization code transmitted by the node B on the downlink pilot channel of the carrier frequencies in the multicarrier network. The UE may then report the channel quality back to the node B.
