Abstract
A radio access network node (e.g., Base Station Subsystem), a wireless device (e.g., a mobile station), and various methods are described herein for improving the allocation of radio resources in wireless communications. In one embodiment, the radio access network node and wireless device implement a fixed uplink allocation technique. In another embodiment, the radio access network node and wireless device implement a flexible downlink allocation technique.
Claims16
A radio access network (RAN) node configured to interact with a core network (CN) node and a wireless device, the RAN node comprising:
- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the RAN node is operable to:
- receive, from the wireless device, one or more repetitions of an access request message, wherein the access request message comprises:
- an indication of a number of data blocks the wireless device intends to transmit to the RAN node;
- and
- transmit, to the wireless device, one or more repetitions of an uplink assignment message, wherein the uplink assignment message comprises:
- an indication of a number of pre-allocated radio blocks on a packet data traffic channel;
- an indication (NTX, UL) of an Uplink (UL) coverage class;
- and
- an indication of a starting point of the pre-allocated radio blocks that the wireless device is to use to transmit a first data block from the data blocks that the wireless device intends to transmit to the RAN node,
- wherein the pre-allocated radio blocks are allocated such that each of the data blocks does not need to be transmitted contiguously with respect to one another by the wireless device.
A method in a radio access network (RAN) node—configured to interact with a core network (CN) node—and a wireless device, the method comprising:
- receiving, from the wireless device, one or more repetitions of an access request message, wherein the access request message comprises:
- an indication of a number of data blocks the wireless device intends to transmit to the RAN node;
- and
- transmitting, to the wireless device, one or more repetitions of an uplink assignment message, wherein the uplink assignment message comprises:
- an indication of a number of pre-allocated radio blocks on a packet data traffic channel;
- an indication (NTX, UL) of an Uplink (UL) coverage class;
- and
- an indication of a starting point of the pre-allocated radio blocks that the wireless device is to use to transmit a first data block from the data blocks that the wireless device intends to transmit to the RAN node,
- wherein the pre-allocated radio blocks are allocated such that each of the data blocks does not need to be transmitted contiguously with respect to one another by the wireless device.
