Abstract: Techniques to detect for DTX frames in a “primary” transmission that may be sent in a non-continuous manner using a “secondary” transmission that is sent during periods of no transmission for the primary transmission. The primary and secondary transmissions may be the ones sent on the F-DCCH and Forward Power Control Subchannel, respectively, in an IS-2000 system. In one method, a determination is first made whether or not a frame received for the primary transmission in a particular frame interval is a good frame (e.g., based on CRC). If the received frame is not a good frame, then a determination is next made whether the received frame is a DTX frame or an erased frame based on a number of metrics determined for the primary and secondary transmissions. The metrics may include symbol error rate of the received frame, secondary transmission (e.g., PC bit) energy, and received frame energy.

Abstract: A method to improve the sending of scheduling information, particularly for Time Division-High-Speed Uplink Packet Access (TD-HSUPA) operation is described. When T-WAIT is configured at a large value which is above a threshold, and when the UE transitions from having a grant to not having a grant, and the TEBS is larger than zero, if the UE does not receive a grant within a time window, the UE may send scheduling information via the E-RUCCH without waiting for the T-WAIT timer to expire.

Abstract: Carrier management in a wireless communication device assigned a set of two or more carriers by a wireless communication network is disclosed. In one aspect, a method of carrier management includes transmitting data over the wireless communication network on one or more carriers forming a subset of active carriers from the set of carriers assigned to the wireless communication device. A first performance metric is determined indicative of operating conditions across the set of carriers assigned to the wireless communication device. A desired number of carriers on which to transmit data based on the first performance metric is determined. The desired number of carriers on which to transmit data is compared with the number of carriers in the subset of active carriers. The subset of active carriers is dynamically adjusted based on the comparison and subsequent data is transmitted over the wireless communication network using the adjusted subset of active carriers.

Abstract: Methods and apparatus are provided for operating in a first RAN at a working frequency, determining a priority of measurement tasks enabled by the first RAN, and dynamically scheduling the tasks according to the priority. For certain aspects, the first RAN may be a TD-SCDMA network. The measurement tasks are intended to measure at least one parameter of a serving cell in the first RAN on a primary frequency, at least one cell in the first RAN on at least one frequency other than the primary frequency, one or more cells in at least one RAN other than the first RAN (e.g., a GSM network) or any combination thereof. This dynamic assignment allows the UE to make scheduling decisions on which frequencies and RANs to measure, as well as how often these frequencies and RANs are measured, thereby providing for more efficient use of idle slots over conventional haphazard scheduling.

Abstract translation: 提供了以工作频率在第一RAN中操作的方法和装置，确定由第一RAN启用的测量任务的优先级，并根据优先级动态地调度任务。 对于某些方面，第一RAN可以是TD-SCDMA网络。 测量任务旨在测量主频率上的第一RAN中的服务小区的至少一个参数，在主频率以外的至少一个频率上的第一RAN中的至少一个小区，至少至少一个或多个小区 除了第一RAN之外的一个RAN（例如，GSM网络）或其任何组合。 该动态分配允许UE对要测量的哪些频率和RAN进行调度决定，以及测量这些频率和RAN的频率，从而提供比常规随机调度更有效地利用空闲时隙。

Abstract: When a user equipment (UE) is communicating wirelessly over a wireless communication network and terminates wireless communication temporarily due to power limit constraints (such as to satisfy a specific absorption rate (SAR) threshold), the UE may maintain its radio access network (RAN) identification (ID) and domain context, in order to quickly resume wireless communication, and avoid upper layer connection setup, once the UE is no longer power limited.
