Embodiment 1

[0024] The embodiment of the present invention provides a resource allocation method for multiple remote radio units sharing a cell, such as figure 1 As shown, the steps include:

[0025] S101. In a multi-radio remote unit cell, measure test values ​​of reference signals of user equipment in the cell under each radio remote unit.

[0026] S102. Select the remote radio unit with the highest test value as the working remote radio unit of the user equipment.

[0027] It should be noted here that the test value of the reference signal mentioned in step S102 can be any of the following: reference signal received power (RSRP, reference signal receiving power); or the signal-to-interference-plus-noise ratio of the sounding reference signal ( SRS SINR, sounding reference signal; signal to interference plus noise ratio); or demodulation reference signal signal to interference plus noise ratio (DMRS SINR, demodulation reference symbol signal to interference plus noise ratio).

Embodiment 2

[0032] The embodiment of the present invention provides a resource allocation method for multiple remote radio units sharing a cell, such as figure 2 As shown, the steps include:

[0033] S201. In a cell with multiple remote radio units, the base station measures test values ​​of reference signals of user equipment in the cell under each remote radio unit.

[0034] S202. The base station selects the remote radio unit with the highest test value of the reference signal as a working remote radio unit of the user equipment.

[0035] S203. Compare the difference between the reference signal test value of the user equipment under other remote radio units in the cell and the reference signal test value of the user equipment under its working remote radio unit, and if the difference is less than the preset value, simultaneously The other remote radio unit is selected as the working remote radio unit.

[0036] It can be understood that, usually, when the user equipment is the centr...

Embodiment 3

[0046] An embodiment of the present invention provides a resource allocation device for multiple radio remote units sharing a cell, such as Figure 5 As shown, the device includes a reference signal measuring unit 51 and an selecting unit 52 .

[0047] The reference signal measurement unit 51 is used to measure the test value of the reference signal of the user equipment in the cell under each remote radio unit.

[0048] The selection unit 52 is configured to select the remote radio unit with the highest test value measured by the reference signal measurement unit as the working remote radio unit of the user equipment.

[0049] The resource allocation device for multiple remote radio units sharing a cell provided by the embodiment of the present invention can, under the condition that multiple remote radio units share a cell, according to the test value of the reference signal of the user equipment in the cell under each remote radio unit The user equipment selects the corres...

Abstract

The invention provides a method and a device for co-cell resource distribution of multiple remote radio units, relates to the communication field and aims at reducing the waste of channel resources in the co-cell resource distribution of multiple remote radio units in one embodiment. The method for co-cell resource distribution of multiple remote radio units is characterize in that in the cells of the multiple remote radio units, a base station measures the test values of reference signals of user equipment in the cells in each remote radio unit, and the remote radio unit with the highest test value as the working remote radio unit of the user equipment. The method and the device for the co-cell resource distribution of multiple remote radio units are applied to channel resource distribution.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource allocation method and device for a common cell of multiple radio remote units. Background technique [0002] In the scenario where multiple RRUs (radio remote units, remote radio units) share a cell, multiple RRUs under the same indoor baseband processing unit are physically distributed in different sites, but they are logically in the same cell, so each The cell parameters such as the number of carriers, frequencies, and channel configurations of the RRUs are the same. In this case, for the downlink channel, each RRU transmits the same PDSCH / PDCCH (physical downlink shared channel, physical downlink shared channel / physical downlink control channel, physical downlink control channel) signal; for the uplink channel, each RRU jointly receives Or choose to receive a PUCCH / PUSCH (physical uplink control channel, physical uplink shared channel physical uplink shared chann...
