Problems solved by technology

However, in this case, if the use of resources has been stable, the advantages of scheduling flexibility cannot be taken advantage of, and in typical frequency selective fading channels, there will be a situation in the deep fading interval for a long time, resulting in communication increase in difficulty
[0007] Therefore, it is currently impossible to realize the stability of the service and the frequency diversity gain brought about by frequency hopping

Embodiment 1

[0034] In this embodiment, a method for transmitting frequency hopping signaling based on semi-stable scheduling is provided.

[0035] Such as figure 2 As shown, the method for transmitting frequency hopping signaling according to this embodiment includes: step S202, the base station pre-allocates (predefined) frequency hopping parameters for the user, and the user performs frequency hopping transmission according to the frequency hopping parameters; step S204, when the user requests During scheduling, users use pre-allocated frequency hopping parameters or use new frequency hopping parameters allocated by the base station for frequency hopping transmission.

[0036] Preferably, in figure 2 On the basis of the above processing shown, the following processing may be further included: when the base station detects that the user has no data transmission, or the user requests not to transmit data, the user stops frequency hopping.

[0037] Wherein in step 202, the base station m...

Embodiment 2

[0050] In this embodiment, a frequency hopping mode and a scheduling signaling configuration method are provided.

[0051] The method includes the following processing: when all or part of the frequency hopping users in the system use different frequency bandwidths: the users adopt the group frequency hopping mode, and the scheduling signaling is configured as single-user scheduling signaling; or the users adopt multi-granularity frequency hopping mode, the scheduling signaling is configured as group scheduling signaling; and when all or part of the frequency hopping users in the system use the same frequency bandwidth: the users adopt the single-granularity frequency hopping mode.

[0052] The above various modes will be described in detail below.

[0053] 1. Group frequency hopping mode

[0054] In the group frequency hopping mode, the following processing is performed: (1) put users with different granularities into one or more virtual groups, for example, users whose freq...

Abstract

The invention discloses a method for transmitting frequency hopping signaling, which comprises the following steps: step S202, using a base station to pre-distribute frequency hopping parameters for users, and enabling the users to perform frequency hopping transmission according to the frequency hopping parameters; and step S204, enabling the users to use the pre-distributed frequency hopping parameters when the users request the dispatching, or using the base station to perform the frequency hopping transmission on new frequency hopping parameters distributed by the base station for the users. In addition, the invention further discloses a method for configuring frequency hopping mode and dispatching signaling. By using the invention, all the users in neighborhood can be always kept orthogonal, so that the interference on the users is randomized, bandwidth single granularity and multi-granularity can be retained to always keep the continuity of occupying subcarriers, and the demand of the signaling is reduced.
