Problems solved by technology

Unless the WTRU has a relatively large amount of data to transmit, it can be inferred that using shared resources in this manner is a waste

Abstract

A method and apparatus for signaling in a Wireless Transmit Receive Unit (WTRU) are provided. The method includes the WTRU receiving a value for a maximum number of retransmissions and retransmitting data in a plurality of hybrid automatic repeat request (HARQ) processes. The WTRU is configured to receive cell-specific, fixed or absolute grants on a broadcast channel.

Description

technical field [0001] This application relates to wireless communications. Background technique [0002] In most cellular communication systems, access to radio resources is controlled by the radio network. When a wireless transmit / receive unit (WTRU) needs to transmit data to the network, the WTRU obtains radio resource access before transmitting its data payload. To achieve this in a 3rd Generation Partnership Project (3GPP) network, for example, the WTRU must gain access to the Random Access Channel (RACH). Access to the RACH is contentious and there are mechanisms to reduce the likelihood of collisions, ie, when two WTRUs access the resource at the same time. [0003] The procedure for random access includes a preamble phase with power ramp-up, followed by channel acquisition information and message transmission. Due to the contentious nature of RACH, to avoid the WTRU occupying shared radio resources for a long time, and since there is no power control, relatively s...
