Embodiment 1

[0024] refer to figure 1 , shows a flow chart of steps of a space division multiplexing method according to Embodiment 1 of the present application.

[0025] The space division multiplexing method of the present embodiment comprises the following steps:

[0026] Step S102: When the second service accesses one or more variable-attribute downlink time slots, from which (that is, in the one or more variable-attribute downlink time slots accessed by the second service) can bear the first service In the variable attribute downlink time slot, it is determined that the first service occupies all the time slot resources of the variable attribute downlink time slot as the space division multiplexable time slot.

[0027] Taking the first service as H service and the second service as R4 service as an example, the variable attribute time slot technology supports setting the service time slots of some carriers under the cell as variable attribute time slots, and these time slots can carr...

Embodiment 2

[0033] refer to figure 2 , shows a flow chart of steps of a space division multiplexing method according to Embodiment 2 of the present application.

[0034] In this embodiment, it is assumed that there are three variable attribute downlink time slots TS3, TS4 and TS5.

[0035] The space division multiplexing method of the present embodiment comprises the following steps:

[0036] Step S202: The three variable attribute downlink time slots of the space division carrier currently carry the first service.

[0037] In this embodiment, the first service is set to be the R4 service, and the second service that can be time-slot space-division multiplexed with the first service at this time is the H service. Of course, it is not limited thereto. In practical applications, the first service may also be an H service, and at this time, the second service that can be time-slot space-division multiplexed with the first service may be an R4 service or an H service.

[0038] In this ste...

Embodiment 3

[0052] refer to image 3 , shows a flowchart of steps of a space division multiplexing method according to Embodiment 3 of the present application.

[0053] In this embodiment, an indoor distributed system multi-channel cell (a cell composed of multiple single-channel RRUs or multi-channel RRUs) is set, and a mixed-service HSPA (High-Speed ​​Packet Access, high-speed packet access) cell is configured by default. 2:4 configuration, configure 1 HSPA carrier, TS2 is EPUCH (Enhanced-Physical Uplink Channel, enhanced uplink physical channel), TS3, TS4, TS5 are PDSCH (Physical Downlink Shared Channel, physical downlink shared channel), when the configuration is variable After the slot is switched, all downlink business time slots are HS-PDSCH (High Speed ​​Physical Downlink Shared Channel) resources and DPCH (Dedicated Physical Channel, dedicated physical channel) resource variable attribute time slots. Access sequence: channel A accesses UE1 32 / 128k R4 services, channel B accesses...

Abstract

The invention provides a space division multiplexing method and a space division multiplexing device. The space division multiplexing method comprises the following steps: when one or more variable attribute downlink time slots are accessed to a second service, the time slot whose all time slot resources of the variable attribute downlink time slots are occupied by a first service is determined as a spacable division multiplexing time slot from the variable attribute downlink time slots carrying the first service, and whether the first service and the second service are paired successfully on the confirmed spacable division multiplexing time slot, if the pairing is succeeded, the spacable division multiplexing time slot with succeeded pairing is spaced and multiplexed, so that the first service and the second service can be transmitted synchronously through the spacable division multiplexing time slot. With the adoption of the method and the device, a space division carrier wave resource utilization rate is increased, and the cell downlink access is increased.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a space division multiplexing method and device. Background technique [0002] With the continuous increase of data users and the increasingly strong demand for high-speed data services, the throughput and spectrum efficiency of wireless communication systems such as TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) systems have become constraints The bottleneck of the deep development of data business. For this reason, space division multiplexing came into being. Taking HSDPA (High Speed ​​Downlink Packet Access) space-division multiplexing as an example, HSDPA space-division multiplexing realizes code channel multiplexing through software upgrades without changing the network settings, which greatly improves Effects of TD-SCDMA system data throughput and spectral efficiency. [0003] Existing space division multiplexing utilizes differen...
