Definitions
- the downlink subframe n schedules the physical downlink shared channel (PDSCH) of the subframe, and the downlink subframe n schedules the n+k subframe.
- Physical Uplink Shared CHannel (PUSCH) of the frame as shown in Figure 1.
- the physical downlink shared channel (PDSCH) resource is allocated to the to-be-scheduled downlink UE to which the PDCCH resource is allocated, and the physical uplink shared channel PUSCH resource is allocated to the uplink UE to be scheduled to which the PDCCH resource is allocated.
- PDSCH physical downlink shared channel
- the total amount of PDCCH resources required for all downlink user equipment UEs to be scheduled and all required to be scheduled for uplink UEs according to all available physical downlink control channel PDCCH resources are allocated to the downlink UE to be scheduled and the uplink UE to be scheduled, including:
- the total amount of PDCCH resources required for all downlink UEs to be scheduled and all to be processed The total amount of PDCCH resources required for scheduling the uplink UE, and determining the total amount of PDCCH resources allocated to all the to-be-scheduled downlink UEs and the total amount of PDCCH resources allocated to all the to-be-scheduled uplink UEs, respectively;
- a channel resource allocation apparatus provided by an embodiment of the present invention includes:
- a first processor configured to use, according to all available physical downlink control channel PDCCH resources, a total amount of PDCCH resources required for all downlink user equipment UEs to be scheduled, and a total amount of PDCCH resources required for all uplink UEs to be scheduled, respectively, to be scheduled
- the downlink UE and the uplink UE to be scheduled are allocated PDCCH resources; and the physical downlink shared channel PDSCH resource is allocated to the downlink UE to be scheduled with the allocated PDCCH resource, and the physical uplink shared channel is allocated to the uplink UE to be scheduled with the allocated PDCCH resource PUSCH resources.
- the total amount of PDCCH resources required for all downlink user equipment UEs to be scheduled and the total amount of PDCCH resources required for all uplink UEs to be scheduled are respectively
- the scheduled downlink UE and the uplink UE to be scheduled are allocated PDCCH resources; the physical downlink shared channel PDSCH resource is allocated to the downlink UE to be scheduled with the allocated PDCCH resource, and the physical uplink shared is allocated to the uplink UE to be scheduled with the allocated PDCCH resource Channel PUSCH resource.
- the PDSCH resource allocation is performed on the UEs in the queue Q3_UE_dw in sequence. If the PDSCH resource allocation fails, Then the UE cannot be scheduled in this subframe;
- both the PUSCH resource and the PDSCH resource are reserved, and when there are unassigned uplink UEs and downlink UEs, the UEs with small CCE requirements in the heads UEs of the Q1 '_UE_dw and Q1 '_UE_ul are preferentially allocated channel resources;
- a channel resource allocation apparatus includes:
- the computer program instructions can also be stored in a computer readable memory that can direct a computer or other programmable data processing device to operate in a particular manner, such that the instructions stored in the computer readable memory produce an article of manufacture comprising the instruction device.
- the apparatus implements the functions specified in one or more blocks of a flow or a flow and/or block diagram of the flowchart.

Abstract
L'invention porte sur un procédé et un dispositif d'attribution de ressources de canal, pour attribuer raisonnablement des ressources de canal et améliorer l'utilisation des ressources de canal. Le procédé consiste à : en fonction de toutes les ressources de canal de commande de liaison descendante physique (PDCCH) disponibles, du nombre total de toutes les ressources PDCCH requises pour un équipement utilisateur (UE) de liaison descendante à planifier, et du nombre total de toutes les ressources PDCCH requises pour un UE de liaison montante à planifier, attribuer des ressources PDCCH pour l'UE de liaison descendante à planifier et l'UE de liaison montante à planifier respectivement ; et attribuer une ressource de canal partagé de liaison descendante physique (PDSCH) pour l'UE de liaison descendante à planifier auquel la ressource PDCCH a été attribuée, et attribuer une ressource de canal partagé de liaison montante physique (PUSCH) pour l'UE de liaison montante à planifier auquel la ressource PDCCH a été attribuée.
