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.
Claims24
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 CN node, a paging request message associated with the wireless device;
- transmit, to the wireless device, one or more repetitions of a page message;
- receive, from the wireless device, one or more repetitions of an access request message requesting resources for transmitting a page response message;
- 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 block(s) on a packet data traffic channel;
- and
- an indication (NTX, UL) of an Uplink (UL) coverage class;
- and
- receive, from the wireless device, one or more repetitions of a page response message, wherein the page response message comprises:
- uplink payload, wherein the uplink payload is received in the pre-allocated radio block(s), and wherein the page response message is repeated according to the UL coverage class.
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 CN node, a paging request message associated with the wireless device;
- transmitting, to the wireless device, one or more repetitions of a page message;
- receiving, from the wireless device, one or more repetitions of an access request message requesting resources for transmitting a page response message;
- 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 block(s) on a packet data traffic channel;
- and
- an indication (NTX, UL) of an Uplink (UL) coverage class;
- and
- receiving, from the wireless device, one or more repetitions of a page response message, wherein the page response message comprises:
- uplink payload, wherein the uplink payload is received in the pre-allocated radio block(s), and wherein the page response message is repeated according to the UL coverage class.
A wireless device configured to interact with a radio access network (RAN) node, the wireless device 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 wireless device is operable to:
- receive, from the RAN node, one or more repetitions of a page message;
- transmit, to the RAN node, one or more repetitions of an access request message requesting resources for transmitting a page response message;
- receive, from the RAN node, one or more repetitions of an uplink assignment message, wherein the uplink assignment message comprises at least:
- an indication of a number of pre-allocated radio block(s);
- and
- an indication (NTX, UL) of an Uplink (UL) coverage class;
- and
- transmit, to the RAN node, one or more repetitions of a page response message, wherein the page response message comprises:
- uplink payload, wherein the uplink payload is transmitted in the pre-allocated radio block(s), and wherein the page response message is repeated according to the UL coverage class.
A method in a wireless device configured to interact with a radio access network (RAN) node, the method comprising:
- receive, from the RAN node, one or more repetitions of a page message;
- transmit, to the RAN node, one or more repetitions of an access request message requesting resources for transmitting a page response message;
- receive, from the RAN node, one or more repetitions of an uplink assignment message, wherein the uplink assignment message comprises at least:
- an indication of a number of pre-allocated radio block(s);
- and
- an indication (NTX, UL) of an Uplink (UL) coverage class;
- and
- transmit, to the RAN node, one or more repetitions of a page response message, wherein the page response message comprises:
- uplink payload, wherein the uplink payload is transmitted in the pre-allocated radio block(s), and wherein the page response message is repeated according to the UL coverage class.
