Abstract

The method of the invention can stop the sending window of the RLC layer and send the non-empty buffer, and during the running period of the t-PollRecransming timer, the RLC layer indicates the MAC layer not to initiate scheduling authorization, thereby promoting the MAC layer to release the empty resource and avoiding invalid authorization and resource waste.
Description
Technical Field
The invention relates to the technical field of communication, in particular to a resource management method.
Background
In a 3G/4G wireless communication system, a Data Packet received by a base station from a core network first passes through a PDCP (Packet Data Convergence Protocol) layer, the PDCP layer is compressed and encrypted by an IP header, and then transferred to an RLC (Radio Link Control) layer, the RLC layer is segmented and concatenated according to a transmission requirement of an MAC (Media Access Control) layer, and then the Data Packet is transferred to the MAC layer, and finally a wireless signal is formed from an air interface connected to the MAC layer and transmitted.
In the prior art, the RLC layer has data transmission modes according to the characteristics and requirements of service transmission, which are: a transmission mode with a connection acknowledgement guarantee mechanism (e.g., AM mode) and a transmission mode without connection acknowledgement guarantee.
For the transmission with connection confirmation guarantee, after the sending end sends a data packet, the receiving end needs to feed back a confirmation packet according to the receiving condition to inform the sending end whether the receiving is correct, and the sending end determines whether retransmission is needed or not according to the result.
Currently, the feedback acknowledgement and retransmission mechanism adopted by the RLC AM mode is briefly described as follows:
a fixed size transmission window (vt (a) -vt (ms)) and a reception window (vr (r) -vr (mr)) are set. As shown in fig. 1, each time a PDU (Protocol Data Unit) is sent by a sending end, the sending end buffers the PDU in the sending window according to a sent sequence number, an initial position vt (a) of the sending window is always updated to a buffer position of a first Data packet to be fed back and confirmed to be successfully received, and only a successful receiving message fed back by a receiving end is continuously received, the corresponding buffer packet is emptied and has an opportunity to be pushed backward. Once the transmission window is full, vt(s) ═ vt (ms), no new data PDUs are transmitted. The RLC AM mode receive window and corresponding state variables are shown in fig. 2. The receiving end also holds the start position vr (r) of the receiving window at the first buffer position where the data packet is not received successfully, and only if the receiving end confirms successful receiving, the receiving end will deliver the data packet to the higher layer, and the receiving end will clear the buffer and have an opportunity to move backward.
An ARQ (Automatic Repeat request) process in RLC AM mode includes retransmission, polling and status reporting, and its trigger mechanism is briefly described as follows:
ARQ retransmission conditions: a) the t-PollRecransingtimer expires; and, b) the transmission buffer and the retransmission buffer are both empty, or, c) the transmission window is stopped.
Polling transmission conditions: a) PDU _ WITHOUT _ POLL > -polPDU or BYTE _ WITHOUT _ POLL > -polByte; or, b) both the transmission buffer and the retransmission buffer are empty; or, c) the transmission window stops. t-PollRecransmitting is started or restarted after initiating a polling report.
Status report triggering conditions: a) after the transmitting side initiates polling, the receiving side meets the condition that the PDU is discarded or SN < VR (MS) or SN > -VR (MR); or b) the receiving side detects the PDU reception failure and the t-Reordering times out.
However, in RLC AM mode, in the scenario that the transmission buffer is not empty and the transmission window is stopped, the transmitting end initiates a polling report, and starts or restarts t-poll retransmission. Before the t-PollRecransmitting timer expires, RLC retransmission cannot occur, the sending window stops, new RLC data transmission cannot occur, and meanwhile, because the sending cache is not empty, the MAC layer cannot release empty resources or still schedules the user, so that empty resources are wasted.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention.
It should be noted that the words "first", "second", "third" and "fourth" are used herein only to distinguish the same names from each other, and do not imply a relationship or order between the names.
At present, when the RLC layer sending buffer and the retransmission buffer are both empty, for an uplink, the terminal MAC layer generates ending BSR and sends the ending BSR to the base station, and for a downlink, the base station MAC layer generates a report that the buffer is empty. And the base station side continuously receives the uplink ending BSR times or counts the number of times of the downlink buffer empty report to exceed the set maximum buffer empty times, and the MAC layer of the base station side releases the air interface wireless resources.
However, when the transmission window in the RLC AM mode on the base station side or the terminal side is stopped, but the timer is in the running period (that is, neither the buffer nor the retransmission buffer is empty), at this time, the MAC layer on the base station side may not release the air interface resource or may still schedule the user, which results in waste of the air interface resource.
Example one
The embodiment provides a method for resource management by combining an RLC layer and a MAC layer, which includes step a 01:
step A01, when the sending window in the base station side RLC AM mode stops, but the timer is in the running period, the base station side RLC layer sends the indication information that the buffer is empty to the base station side MAC layer, so that the base station side MAC layer interactively releases the air interface wireless resource with the terminal according to the indication information.
The RLC layer and MAC layer joint resource management method of this embodiment improves the utilization efficiency of air interface radio resources through cross-layer information interaction between the RLC layer and the MAC layer on the base station side.
In an alternative implementation, the foregoing method may further include the following step a02 not shown in the figure:
a02, if the base station side RLC layer receives the status report information sent by the opposite terminal RLC layer, sending the indication information of non-empty buffer memory to the base station side MAC layer, so that the base station side MAC layer interacts with the terminal according to the indication information of non-empty buffer memory.
Of course, in other embodiments, step a02 here may also be a 02' not shown in the figure:
a02', if the timer in the base station side RLC layer expires and the retransmission buffer is not empty, sending indication information that the buffer is not empty to the base station side MAC layer, so that the base station side MAC layer interacts with the terminal according to the indication information that the buffer is not empty.
In the method of this embodiment, through cross-layer information interaction between the base station side RLC layer and the base station side MAC layer, the transmission window in the base station side RLC AM mode is stopped, but when the timer is in the running period, the base station side MAC layer can release the air interface resource, thereby improving the utilization efficiency of the air interface radio resource.
Example two
As shown in fig. 3, the present embodiment provides a resource management method combining an RLC layer and a MAC layer, and the specific method includes steps B01 and B02:
b01, the MAC layer at the base station side receives the indication information that the buffer sent by the RLC layer at the base station side is empty; the indication information is sent when a sending window of an RLC layer at a base station side stops in an RLC AM mode but a timer is in a running period;
b02, the MAC layer of the base station side releases the current air interface wireless resource according to the indication information.
Optionally, in practical applications, after the step B02 is executed, the method shown in fig. 3 further includes the following step B03:
b03, the MAC layer of the base station side does not send the scheduling authorization information to the opposite end any more.
That is to say, for the scenario that the sending window of the RLC layer of the base station side stops and the sending buffer is not empty, during the running period of the t-poll retransmission timer, the MAC layer of the base station side does not initiate the scheduling authorization information, so that invalid authorization and resource waste can be effectively avoided.
It is understood that, in the methods of the first and second embodiments, in the RLC AM mode on the base station side, the RLC layer on the base station side initiates a polling report and starts or restarts the t-poll retransmission timer when the transmission window is stopped. During the running period of the t-PollRecransmitting timer, no matter whether the sending buffer of the base station side RLC layer is empty or not, the base station side RLC layer needs to issue a buffer empty indication to the MAC layer, so as to promote the base station side MAC layer to release air interface radio resources, avoid that the base station side MAC layer still assembles TB blocks (transport blocks) and requests the base station side RLC layer for data, and the base station side RLC layer cannot send new data due to the stop of a sending window, thereby causing the invalid utilization of resources.
In another alternative implementation, the method of the second embodiment may further include the following step B04 not shown in the figure:
b04, the MAC layer of the base station side receives the indication information of non-empty buffer memory sent by the RLC layer of the base station side, and interacts with the terminal according to the indication information of non-empty buffer memory;
the buffer non-empty indication information is sent when the base station side RLC layer receives status report information sent by an opposite terminal RLC layer, or the buffer non-empty indication information is sent when the timer in the RLC layer expires and the retransmission buffer is not empty.
That is, the base station side RLC layer sends a "buffer not empty" indication to the MAC layer of the base station side until the base station side RLC layer receives a status report sent by the peer RLC layer, which causes the transmission window to be pushed forward, or the t-poll retransmission timer expires, and the retransmission buffer is not empty, and then performs the subsequent operation according to the flow in the prior art.
According to the method for managing the combined resources of the RLC layer at the base station side and the MAC layer at the base station side, the utilization efficiency of air interface wireless resources is improved and invalid authorization and resource waste are avoided through cross-layer information interaction of the RLC layer at the base station side and the MAC layer at the base station side.
EXAMPLE III
The present embodiment provides a method for resource management by combining an RLC layer and an MAC layer, where the specific method includes step C01:
c01, when the sending window in terminal side RLC AM mode stops, but the timer is in the running period, the terminal side RLC layer sends the indication information that the buffer is empty to the terminal side MAC layer; and enabling the terminal side MAC layer to generate ending BSR information for indicating the base station side MAC layer to release air interface wireless resources according to the indication information.
The RLC layer and MAC layer joint resource management method of this embodiment improves the utilization efficiency of air interface radio resources through cross-layer information interaction between the terminal side RLC and the terminal side MAC. Namely, an ending BSR generation mechanism is optimized, and on the basis that an ending BSR is generated by an original terminal side RLC layer sending buffer being a null terminal side MAC layer, the ending BSR is generated under the condition that a terminal side RLC layer sending window stops and the sending buffer is not null, so that the base station side MAC layer is facilitated to release air interface resources, and invalid utilization of the resources is avoided.
Further, the method of the third embodiment further comprises the following step C02 or C02' which is not shown in the figure:
and C02, if the terminal side RLC layer receives the status report information sent by the opposite terminal RLC layer, sending cache non-empty indication information to the terminal side MAC layer, so that the terminal side MAC layer interacts with the base station according to the cache non-empty indication information.
C02', if the timer in the terminal side RLC layer expires and the retransmission buffer is not empty, sending indication information that the buffer is not empty to the terminal MAC layer, so that the terminal side MAC layer interacts with the terminal according to the indication information that the buffer is not empty.
It can be understood that, until the terminal side RLC layer receives the status report sent by the peer side RLC layer, the sending window is pushed forward, or the retransmission buffer is not empty when the t-poll retransmission timer expires, the terminal side RLC layer issues a "buffer non-empty" indication to the MAC layer of the terminal side, and then performs the subsequent operation according to the prior art procedure.
Example four
The embodiment provides a resource management method combining an RLC layer and a MAC layer, which specifically includes steps D01 and D02:
d01, the MAC layer of the terminal side receives the indication information that the buffer sent by the RLC layer of the terminal side is empty; the indication information is sent when the terminal side RLC layer stops sending windows in a terminal side RLC AM mode but a timer is in a running period;
d02, the terminal side MAC layer generates ending BSR information according to the indication information, and sends the ending BSR information to the base station side MAC layer, so that the base station side MAC layer releases air interface wireless resources according to the ending BSR information.
It should be noted that the method of this embodiment further includes the following step D03:
d03, the terminal side MAC layer does not initiate the scheduling request information to the opposite side MAC layer any more.
In this embodiment, the utilization efficiency of air interface radio resources is improved through the cross-layer information interaction between the terminal side RLC and the terminal side MAC.
Of course, in a specific application, if the terminal-side RLC layer receives status report information sent by the peer-side RLC layer, or if the timer expires and the retransmission buffer is not empty in the terminal-side RLC layer, the terminal MAC layer also receives indication information that the buffer sent by the terminal RLC layer is not empty, so that the terminal-side MAC layer interacts with the base station according to the indication information that the buffer is not empty.
In addition, when the sending buffer and the retransmission buffer of the base station side RLC layer/the terminal side RLC layer are empty or the sending window is stopped, the terminal side MAC layer is triggered to generate an uplink ending BSR or a downlink buffer of the base station side MAC layer is generated to be an empty report, the number of times of continuously generating the uplink ending BSR or the number of times of continuously generating the downlink buffer to be the empty report exceeds the maximum buffer to be the empty number, and the base station side MAC layer releases empty radio resources; and the MAC layer no longer initiates SR or scheduling grant.
It should be noted that, when both the sending buffer and the retransmission buffer of the RLC layer are empty, or the MAC layer receives the buffer empty indication initiated by the RLC layer, the terminal does not initiate the SR any more for the uplink service; for downlink service, the base station does not issue scheduling authorization any more. And until the MAC layer receives a cache non-empty indication sent by the RLC layer, the MAC layer decides to initiate SR or scheduling authorization according to the read RLC sending cache or retransmission cache, and further air interface resources are effectively utilized.
