Abstract

The invention discloses a method and equipment for processing resource conflict. The method comprises the following steps of: determining whether sending resources of a multicast and broadcast single-frequency network subframe conflict with sending resources of semi-persistent scheduling data or not; and after determining that the sending resources of the multicast and broadcast single-frequency network subframe conflict with the sending resources of the semi-persistent scheduling data, canceling sending the semi-persistent scheduling data on conflicting resources by a base station, and canceling receiving the semi-persistent scheduling data on the conflicting resources by user equipment. Through the method and the equipment, the problems when the multicast and broadcast single-frequency network subframe conflicts with semi-persistent scheduling resources are solved, and users can receive a semi-persistent scheduling service conveniently and also can receive the multicast and broadcast single-frequency network service.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to a resource conflict processing method and equipment. Background technique

[0002] Currently, LTE (Long Term Evolution, Long Term Evolution) uses high-layer signaling to notify UE (User Equipment, User Equipment) of the MBSFN (MBSFN Multicast Broadcast Single Frequency Network, Multicast Broadcast Single Frequency Network) subframe used by the system.

[0003] The description of ASN.1 (Abstract Syntax Notation One, Abstract Syntax Notation 1) for MBSFN in 36.331v8.5.0 is as follows:

[0004] MBSFN-SubframeConfig::=SEQUENCE{

[0005] radioframeAllocationPeriod ENUMERATED {n1, n2, n4, n8, n16,

[0006] n32},

[0007] radioframeAllocationOffset INTEGER(0..7),

[0008] subframeAllocation CHOICE{

[0009] oneFrame BIT STRING(SIZE(6)),

[0010] fourFrames BIT STRING(SIZE(24))

[0011] }

[0012] MBSFN allocation is divided into ...

Examples

Embodiment 1

[0101] The following will be described with specific embodiments. In the specific implementation, the image 3 The conflict situation shown is illustrated as an example. According to the time and resources for PDCCH to activate SPS data transmission, and the period of SPS, SPS has resources on 5, 6, and 7 PRBs of subframe 7 of radio frame 7, and according to the pattern configured by MBSFN, MBSFN subframes are also in radio frame 7 Subframe 7 appears. Then the resources for sending SPS data conflict with the resources for sending MBSFN subframes. At this time, the sending of SPS data is canceled, and the UE also stops receiving SPS resources on PRBs 5, 6, and 7 of subframe 7 of radio frame 7. If the MBMS service is received on the subframe, the MBMS service will still be received on the subframe.

[0102] After steps 402 and 403, the implementation may further include:

[0103] After the base station cancels sending SPS data on conflicting resources, it sends SPS data on d...

Embodiment 2

[0111] The following will be described with specific embodiments. by image 3 The conflict situation shown is illustrated as an example. According to the time and resources for PDCCH to activate SPS data transmission, and the period of SPS, SPS has resources on 5, 6, and 7 PRBs of subframe 7 of radio frame 7, and according to the pattern configured by MBSFN, MBSFN subframes are also in radio frame 7 Subframe 7 appears. Then the resource for sending SPS data conflicts with the resource for sending the MBSFN subframe. At this time, the SPS data is canceled and sent on PRB 5, 6, and 7 of subframe 7 of wireless frame 7, and subframe 9 is judged to be the latest, non-conflicting, and ok. In the downlink subframe where the SPS data is sent, the SPS data that has been canceled is sent on the 5th, 6th, and 7th PRBs of the subframe 9.

[0112] The UE also stops receiving SPS data on PRBs 5, 6, and 7 of subframe 7 of radio frame 7, and receives SPS data on PRBs 5, 6, and 7 of subfram...

Embodiment 3

[0121] The following will be described with specific embodiments.

[0122] First, the base station notifies the UE through signaling that if the resources for sending MBSFN subframes and the resources for sending SPS data conflict, the SPS data will be sent in the next 2 to 3 subframes.

[0123] by image 3 Take the conflict situation as an example to illustrate, according to the time and resources for PDCCH to activate SPS data transmission, and the cycle of SPS, SPS has resources on 5, 6, and 7 PRBs of subframe 7 of radio frame 7, and according to MBSFN configuration pattern, the MBSFN subframe also appears in subframe 7 of radio frame 7. Then the resources for sending SPS data conflict with the resources for sending MBSFN subframes. At this time, the SPS data is canceled and sent on PRBs 5, 6, and 7 of subframe 7 of radio frame 7, and is sent on PRBs 5 and 6 of subframe 0 of radio frame 8. , Send the canceled SPS data on 7PRB.

[0124] The UE also stops receiving SPS dat...
