Problems solved by technology

However, when the number of PRB (Physical Resource Block, physical resource block) of the PUCCH resource is more, the number of PRBs that can be used for PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) transmission is smaller, and the number of PRBs used for PUSCH transmission The reduction in the number of PRBs will directly affect the uplink transmission rate
Therefore, it is currently not possible to configure more PUCCH resources in the cell, which also results in the inability to allocate more 1BCS resources to carrier aggregation users.
[0004] Due to the limited number of 1BCS resources, when the 1BCS resources in the cell are exhausted, the newly accessed carrier aggregation users will not be able to perform carrier aggregation, which will affect the experience of carrier aggregation users

Embodiment 1

[0030] Aiming at the problems existing in the prior art, Embodiment 1 of the present invention provides a channel selection resource allocation method based on PUCCH format 1B, such as figure 1 As shown, the method for allocating channel selection resources based on PUCCH format 1B may specifically include the following steps:

[0031] Step 101 , the network side device determines the number of carrier aggregation users that can be allocated by the 1BCS resource in the group by using the multiplexing degree of the 1BCS resource and the number of PUCCH resource pairs in the group.

[0032] In the embodiment of the present invention, the network side device uses the 1BCS resource multiplexing degree and the number of PUCCH resource pairs in the group to determine the number of carrier aggregation users that can be allocated by the 1BCS resources in the group. Specifically, it may include but not limited to the following methods: the network The side device may determine the numb...

Embodiment 2

[0048] Based on the same inventive concept as the above method, the embodiment of the present invention also provides a network side device for selecting resources based on the physical uplink control channel PUCCH format 1B channel, such as image 3 As shown, the network side device specifically includes:

[0049] The determination module 11 is used to select the multiplexing degree of 1BCS resources and the number of PUCCH resource pairs in the group by using the 1B channel, and determine the number of carrier aggregation users that can be allocated by the 1BCS resources in the group;

[0050] An allocation module 12, configured to allocate 1BCS resources in the group to the number of carrier aggregation users of the number of carrier aggregation users;

[0051] A scheduling module 13, configured to schedule the carrier aggregation user by using the 1BCS resource in the group.

[0052] The determination module 11 is also used to determine the total number of 1BCS resources ...

Abstract

The invention discloses a method and device for distributing channel selection resources based on PUCCH format 1B. The method comprises the following steps: the network side device determines the number of the carrier aggregation users that can be distributed with 1B channel selection (1BCS) resources in the group according to a 1BCS resource reusing degree and a PUCCH resource pair number in the group; the network side device distributes the 1BCS resources in the group to the carrier aggregation users, and dispatches the carrier aggregation users according to the 1BCS resources in the group. According to the embodiment of the invention, the number of the carrier aggregation users accessed in a cell is increased through improving the 1BCS resource reusing degree on the premise that the uplink rate of the cell is not affected, so that the number of the carrier aggregation users accessed in the cell can be greatly increased; the problem that the newly accessed carrier aggregation users cannot perform carrier aggregation after the 1BCS resources in the cell are exhausted is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for allocating channel selection resources based on PUCCH format 1B. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, in order to support carrier aggregation users, a new PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) ACK (ACKnowledgment, positive confirmation) / NACK (Negative ACKnowledgment, Negative acknowledgment) feedback method, that is, PUCCH format (format) 1b with channel selection (channel selection) method, this method is referred to as 1BCS (1B Channel Selection, 1B channel selection) method, the 1BCS method uses the 2bit (bit ) information, and select one of several specific PUCCH resources to indicate the ACK / NACK information to be sent. [0003] In the prior art, when a carrier aggregation user accesses, a dedicated 1BCS resource is allocated through an RRC (Radio...
