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.

Claims

1. 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 (N_{TX, 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 all repetitions of each of the data blocks are to be transmitted contiguously by the wireless device, and 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.

2. The RAN node of claim 1, wherein the access request message further comprises:

an indication (N_{TX, DL}) of a Downlink (DL) coverage class estimated by the wireless device.

3. The RAN node of claim 1, wherein the uplink assignment message further comprises:

an indication (N_{TX, DL}) of a Downlink (DL) coverage class; and

an indication of starting points of the pre-allocated radio blocks that the wireless device is to use to transmit the data blocks subsequent to the first data block that the wireless device intends to transmit to the RAN node.

4. The RAN node of claim 1, wherein the RAN node is further operable to:

receive, from the wireless device, a portion of the number of data blocks in a portion of the pre-allocated radio blocks, and wherein each of the received data blocks has been repeated according to the UL coverage class.

5. 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 (N_{TX, 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,
