Abstract: Avoidance of uplink synchronization oscillation in TD-SCDMA systems begins when a user equipment receives a downlink SS command from a Node B. The user equipment obtains a previous uplink timing, which may be from a previous sub-frame associated with the downlink SS command. The user equipment would obtain this previous sub-frame associated with the SS command directly from the Node B as an identification of the Node B's sub-frame delay. The user equipment will then calculate the uplink timing for its next updated uplink signal by combining the previous uplink timing with the synchronization adjustment associated with the SS command. The user equipment then transmits its next uplink signal using the new uplink timing.

Abstract: 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.

Abstract: Certain embodiments of the present disclosure proposes a flexible method for scheduling of an uplink transmission simultaneously considering all active connections of a mobile station. A decision on scheduling priority can be made based on a metric that comprises QoS parameters and current traffic measurements. The weight factors may be applied for every QoS parameter per schedule type providing flexibility of the scheduling algorithm. The proposed scheduling algorithm may be applied to satisfy different QoS requirements for each service provider and application by changing weight factors if required.

Abstract: A mobile device capable of communicating on multiple radio access networks simultaneously may concurrently operate calls of a first call type on a first network and a second call type on the second network. As the mobile device approaches the limits of the service area of the second network it may take measurements to result in the call of the second call type to be serviced by the serving cell of the first network which is serving the mobile device for the first call type. In this manner the mobile device may ensure that when it leaves the service area of the second network, the calls of the first call type and second call type are served by the same serving cell in the first network.

Abstract: Methods and apparatuses are provided that include enhancing decoding of multicast broadcast control communications, which can be of a relatively large size. A configuration message related to a broadcast channel structure can be received in multiple instances and/or segmented data units. A receiver can combine multiple instances and/or accumulate segmented data units to obtain and/or decode a control channel over which the configuration message is communicated. Communicating segmented data units of the configuration message can allow a broadcast station to utilize a lower data rate, more reliable modulation and coding scheme to encode the configuration message.

Abstract: A mobile station (MS) of a wireless communications system monitors the paging messages of a serving base station (BS) as well as paging messages of one or more neighboring BSs with sufficient signal strength or signal quality. The MS monitors for paging messages from a set of BSs including the serving BS and the neighboring BSs, during listening intervals. The MS coordinates the listening intervals with the paging intervals of the paging messages. These and other aspects related to monitoring the paging intervals of multiple BSs may help improve paging success rate.
