摘要： Congestion in a radio access network (RAN) associated with transporting uplink information originating from one or more mobile terminals is detected. That detected RAN congestion is reduced using any suitable technique (several examples are described) and may be implemented in one or more nodes in the RAN. One advantageous (but non-limiting) application is to a RAN that supports high speed uplink packet access (HSUPA) and/or one or more enhanced uplink dedicated channels (E-DCHs).

摘要： A method and a receiver (mobile station) are described herein for mitigating interference in a radio signal received from a base station and interfered for example by at least one co-channel base station, at least one adjacent channel base station and/or additive white Gaussian noise. The receiver mitigates the interference by using an enhanced reduced-state sequence estimation (RSSE) technique that selects a best set partition which is used to partition a joint signal set that is a function of symbols and channel coefficients associated with the radio signal. The best set partition is selected by exploiting estimated channel responses and/or other channel parameters like rotation and frequency offsets. And, the best set partition describes which signal states of the joint signal set are to be combined together for reduced-state joint demodulation of the radio signal or reduced-state equalization of a multiple-input-multiple-output (MIMO) channel.

摘要： A method is described herein for reducing the number of feedback bits needed to send channel state information over a feedback channel from a receiving unit (102; 104) (e.g., mobile terminal, base station) to a transmitter unit (104; 102) (e.g., base station, mobile terminal) in a wireless communication system (100). In the embodiment, the receiver unit (102; 104) is capable of performing the following steps: receiving a pilot signal from a transmit antenna located at a transmitter unit (104; 102); analyzing a channel tap associated with the transmit antenna (106-1; 106-2 … 106-3) and exploiting the temporal correlations of the channel tap to generate the following (i) a delta-modulated feedback bit indicative of a real part of a complex coefficient of the channel tap associated with the transmit antenna (106-1; 106-2 … 106-3) and (ii) a delta-modulated feedback bit indicative of an imaginary part of the complex coefficient of the channel tap associated with the transmit antenna; and (3) sending the two feedback bits over a feedback channel to the transmitter unit (104; 102) which analyzes the two feedback bits, and other feedback bits corresponding to other channel taps of this and other transmit antennas (106-1; 106-2 … 106-3), to optimize the subsequent transmission of data to the receiver unit (102; 104).

摘要： In a radio communication system that includes multiple service areas, each service area is associated with a predetermined number or amount of radio communication resources. Each radio communication resource can be used for a prescribed period of time corresponding to one or more time units. An operator or other entity identifies a set of service areas to be tested at an increased effective load. A desired test level (e.g., increased traffic load) is determined, and a corresponding number of radio resource time units is determined to achieve the desired test level conditions. Use of radio communication resources in the determined one or more time units is blocked for a test period. Performance by each service area during the test period is determined.

摘要： The present invention relates to a method and apparatus for adjusting a transmit power control process in a mobile radio communication system (SYS1), wherein transmit power (204) is controlled by issuing power control commands (101, 102) indicating whether the transmit power should be increased or decreased in order to adjust towards a transmission quality target (203a-d), and wherein a first transmit power adjustment step (205a, 205b, 205c) is applied in predefined circumstances. Sequences of issued transmit power control commands (101, 102) are registered (301). The first transmit power adjustment step (205a, 205b, 205c) is adjusted (302) according to a predetermined rule based on transmit power control command sequences (101, 102) following previous instances of applying said first transmit power adjustment step (205a, 205b, 205c).

摘要： A radio base station (104) is described herein that uses a delay reference timing (DRT) extension (402) located within a received high-speed downlink shared channel (HS-DSCH) data frame (110) to detect a buffering delay that is caused by large buffer build ups in transport nodes (112 and 114) that are located on a transport link (106) between a radio network controller (102) and the radio base station (104). In addition, the radio base station (104) can correct a problem if the detected buffering delay is too long by reducing the bit rate of a certain high-speed (HS) user flow or by reducing the maximum bit rate for all of the HS traffic which is going to be sent by the radio network controller (102) over the transport link (106) to the radio base station (104).
