Problems solved by technology

[0026] In the prior art above, the base station and the UE do not have a unified method for determining a relative subset of a TBS, but the E-TFCI reported by the UE carries A relative index value of the TBS in the relative subset, which will cause the TBS finally determined by the base station to be different from the TBS selected by the UE, resulting in data decoding failure, which will cause the entire system to fail to work normally
Moreover, how to determine the metric value of PRRI is not clearly provided in the prior art, and the UE needs an explicit metric value of PRRI to correctly determine the relative subset of TBS, which further makes it difficult for the UE and the base station to determine the same TBS Relative subsets that make the system not work properly

Embodiment 1

[0068] In step 101, the PRRI metric value determined by the base station is: the ratio of the E-PUCH received power scheduled by the base station to the normalized resource unit (that is, a maximum spreading factor code channel) of the interference power, that is, the metric of the PRRI Value contains the value of the power offset. In the first embodiment, the base station determines the metric value PRRI of the PRRI according to the following formula 4:

[0069] PRRI = MIN ( P c P ebase , P RoT P ebase , UPH ) × SF 16 (Equation 4, linear value)

[0070] Among them, the P c is the receiving end power req...

Embodiment 2

[0084] In step 101 of the second embodiment, in the second method, the PRRI metric value determined by the base station is: the received power of the E-PUCH scheduled by the base station is deducted from Δharq_SI and then relative to P ebase The normalized resource unit ratio of , the value of Δharq_SI is not included in the PRRI of the second embodiment, and the base station specifically determines the metric value PRRI of the PRRI according to the following formula 5:

[0085] (Equation 5 linear value)

[0086] Among them, the P c is the receiving end power required by the UE determined by the base station according to the scheduling method, the P c Include the power offset Δharq_SI, which can be: the Δharq power offset corresponding to the highest priority logical channel in the UE’s last reported SI used by the base station for scheduling, or the multiple Δharq power offsets obtained by the base station based on the received E-PUCH The maximum Δharq power offset corre...

Abstract

The invention discloses a selecting method for uplink enhancing transmission format congregation (E-TFC) in the mobile communication, a selecting device and a system thereof. The method comprises the following steps: a basic station determines power resource relative information (PRRI), and transmits the information to user equipment (UE); the basic station and the UE adopt the same determining method to determine a relative sub-congregation in transmission block size (TBS) according to the determined PRRI; the UE selects the TBS from the relative sub-congregation in TBS, and selects the E-TFC according to the selected TBS. The device includes a TBS sub-congregation determining module and an E-TEC determining module which are arranged on the UE. The system further includes a PRRI determining module and a TBS sub-congregation determining module which are arranged on the basic station. By utilizing the method, the device and the system, the accuracy of the data decoding by the basic station by using the uplink enhancing technology can be improved, and the normal operation probability of the mobile communication system can be increased, thus leading the mobile communication system to have more realizability.

Description

technical field [0001] The invention relates to a communication resource control technology in a communication system, in particular to a method, device and system for selecting an uplink enhanced transmission format set (E-TFC) in mobile communication. Background technique [0002] At present, in order to improve the uplink data transmission capability of the communication system, frequency division duplex (FDD) system and time division duplex (TDD) system have successively introduced uplink Enhanced Uplink (Enhanced Uplink) technology further optimizes High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology, and introduces High Speed ​​Packet Access Plus (HSPA+, High Speed ​​Packet Access Plus) in the R7 technology version )technology. [0003] In the existing communication system using HSUPA technology, the use of each channel is as follows: [0004] Transport channels include: Enhanced Transport Channel (E-DCH) and Uplink Enhanced Contro...
