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: 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.

Abstract: In TDD-LTE wireless systems, an additional fourth preamble for the random access channel, called short RACH, may be used. If short RACH signaling is to be used, the random access preamble is transmitted in the uplink pilot time slot (UpPTS) field in the special subframe. The location of the uplink pilot time slot (UpPTS) is next to a downlink subframe. Therefore, interference from neighbor base stations may interfere with the short RACH preamble within the uplink pilot time slot. The interference to the short RACH will prevent the eNodeB from detecting the short RACH preamble and thus prevent the UE from accessing the network. An interference level on an Uplink Pilot Time Slot (UpPTS) may be measured and when the interference level exceeds a threshold value a User Equipment (UE) is instructed to disable short Random Access Channel (RACH) signaling. The UE may then be instructed to enable normal RACH. When the interference level falls below the threshold value the UE is instructed to resume short RACH signaling.

Abstract translation: 在TDD-LTE无线系统中，可以使用称为短RACH的随机接入信道的另外的第四前同步码。 如果要使用短的RACH信令，则在特殊子帧中的上行链路导频时隙（UpPTS）字段中发送随机接入前导码。 上行链路导频时隙（UpPTS）的位置在下行子帧的旁边。 因此，来自相邻基站的干扰可能干扰上行链路导频时隙内的短RACH前导码。 对短RACH的干扰将阻止eNodeB检测短RACH前同步码，从而防止UE接入网络。 可以测量上行链路导频时隙（UpPTS）上的干扰电平，并且当干扰电平超过阈值时，指示用户设备（UE）禁用短随机接入信道（RACH）信令。 然后可以指示UE启用正常的RACH。 当干扰电平低于阈值时，UE被指示恢复短的RACH信令。

Abstract: Allocating transmit power among two or more carriers assigned to a wireless communication device is disclosed. In one aspect, a method of allocating transmit power includes determining a total amount of data transmit power available at the wireless communication device for data transmission over the carriers.

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 translation: 在“主”传输中检测可以以非连续方式发送的DTX帧的技术，使用在主传输的无传输期间发送的“次”传输。 主要和次要传输可以分别是在IS-2000系统中在F-DCCH和前向功率控制子信道上发送的。 在一种方法中，首先确定在特定帧间隔中为主传输接收的帧是否是良好帧（例如，基于CRC）。 如果接收到的帧不是良好的帧，则接着确定接收到的帧是否是基于针对主传输和次传输确定的度量的数目的DTX帧或已擦除的帧。 度量可以包括接收到的帧的符号错误率，二次传输（例如，PC位）能量和接收到的帧能量。
