Method and apparatus for control of enhanced dedicated channel transmissions

摘要

A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. An enhanced uplink medium access control (MAC e/es) entity processes a received scheduling grant to calculate a serving grant. The MAC-e/es entity determines whether both a hybrid automatic repeat (H-ARQ) process for scheduled data and scheduled data are available. If an H-ARQ process for scheduled data and scheduled data are available, the MAC-e/es entity determines whether a serving grant exists. The MAC-e/es entity calculates a remaining power based on maximum allowed power and restricts an E-DCH transport format combination (E-TFC) based on the remaining power. The MAC e/es entity selects an E-TFC using the serving grant and generates a MAC-e protocol data unit. The MAC-e/es entity may process the received scheduled grant is at each transmission time interval or may store the received scheduled grant in a grant list until there is E-DCH data to transmit. 102 108 104 106 E-DCH ) E-DPCCH WTRU E-AGCH 112 NODE-B l RNC E /-114 E-RGCH E-HICH HIGHER LAYER - 202 102 RLC LAYER - 204 MAC LAYER - 206 MAC-d ---- 210 MAC e/es ---- 212 PHYSICAL LAYER -208 FIG. 2 MAC e/es E-TFC SELECTION MULTIPLEXING AND TSN ENTITY SETTING ENTITY SERVING GRANT H-ARQ ENTITY MEMRY PROCESSING ENTITY Q 308 312 314 116 108 110 FIG. 3 AG RG(s) E-HICH E-DCH E-DPCCH
