Abstract

A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. A plurality of primary absolute grants are received, wherein the plurality of primary absolute grants are associated with a TTI. At least one relative grant is received for E-DCH transmission, wherein the at least one relative grant is associated with the TTI. At least one serving grant for E-DCH transmission is determined. A H-ARQ process is identified for use for the TTI. It is determined whether the identified H-ARQ process is available for scheduled data and whether scheduled data is allowed to be transmitted in the TTI based at least on the identified H-ARQ process. On a condition that the identified H-ARQ process is available for scheduled data and scheduled data is allowed to be transmitted in the TTI, scheduled data is allocated for transmission in the TTI.

Dependent claims

A method, implemented by a wireless transmit/receive unit (WTRU), the method comprising:

receiving a plurality of primary absolute grants for enhanced dedicated channel (E-DCH) transmission, wherein the plurality of primary absolute grants are associated with a transmission time interval (TTI);
receiving at least one relative grant for E-DCH transmission, wherein the at least one relative grant is associated with the TTI;
determining at least one serving grant for E-DCH transmission based on at least one primary absolute grant of the plurality of primary absolute grants and the at least one relative grant;
identifying a hybrid automatic repeat request (H-ARQ) process for use for the TTI;
determining whether the identified H-ARQ process is available for scheduled data, wherein only an active H-ARQ process is used for transmission of scheduled data and a non-active H-ARQ process is not used for transmission of scheduled data;
determining whether scheduled data is allowed to be transmitted in the TTI based at least on the identified H-ARQ process;
on a condition that the identified H-ARQ process is available for scheduled data and scheduled data is allowed to be transmitted in the TTI, allocating scheduled data for transmission in the TTI;
calculating a remaining power available for the TTI based on a maximum allowed power for the WTRU;
performing E-DCH transport format combination (E-TFC) restriction based on the remaining power;
selecting an E-TFC from a set of E-TFCs remaining after E-TFC restriction, wherein the E-TFC selection is based at least on the at least one serving grant;
and
transmitting the allocated data in accordance with the identified H-ARQ process.
